At the request of a torque equipment manufacturer, we inspected the feasibility of confirming the positions for tightening bolts. The term "torque" generally refers to "twisting moment" or "rotational moment." There was a request to use a 180-degree web camera, and the camera was sent along with the sample product. The tightness of bolts is considered important across various industries. We hope to contribute to safer product shipments by utilizing image inspection. 【Inspection Settings and Results】 By using EasyInspector's "Color Comparison Inspection and Presence of Specified Color Inspection" function, we were able to detect the tightening positions of two bolts and check whether the bolts had been tightened more than twice. The bolts at the corners were detected by identifying the characteristic colors at each position, allowing us to specify which part was the torque wrench tightening position. To identify the bolt positions located at the top, bottom, left, and right, changes and additions to the inspection conditions are necessary. Additional software or similar tools are required to identify the current bolt positions based on the combinations of pass/fail judgment results.

We have received a request for a simple verification from a manufacturer of metal parts for automobiles. There is a workpiece with a φ8.5 hole, and the areas we want to measure this time are the widths of the flat surfaces on both sides of this φ8.5 hole. First, we will confirm that the φ8.5 hole is correctly made, and then we will check whether the flat surfaces on both sides are each 2.75 mm or more, which will be done through image inspection. Using this hole, we will verify whether the area that serves as the seating surface for the bolt head is φ14 or more. 【Inspection Settings and Results】 The seating surface is completely flat, and it seems that other hole chamfers have an inclination of more than 30 degrees, so I believe we can capture a clear image using coaxial illumination. We took images using a metal plate we had in our company, and I would appreciate it if you could check the materials. This time, we used a 1.3-megapixel camera with a 35mm lens. The total cost for the camera and lens is about 80,000 yen. We used the "Dimension Angle Inspection" function of EasyInspector, and it was possible to conduct the inspection in 0.15 seconds.

We reported on the re-evaluation conducted with DeepSky, which was just released in 2020, using the sample images that you previously inquired about from the comprehensive manufacturer of containers and packaging materials. The inspection was performed using software that employs AI (Deep Learning). By training the software on the areas we want to detect, it can adjust its own setting parameters and recognize them. In actual operations, various patterns of defects (size and characteristics) are expected, so it is necessary to increase the number of training images. [Inspection Settings and Results] "DeepSky" significantly differs from conventional software and detection methods, allowing for the detection of pre-trained feature areas from the screen. I thought that "DeepSky" could be utilized for the inspection of coating amounts of the coating agent that you previously inquired about. Unlike before, it is no longer necessary to increase the number of inspection frames for certain settings. However, it is necessary to prepare multiple images in advance for cases of failure, but since September 2021, it has become possible to augment training images. The function to augment a single defective image into up to 36 images by adjusting brightness, orientation, angle, and noise has been implemented, making it more convenient to use.

If there are chips on the substrate, they are treated as defective products. Electronic component manufacturers pay close attention to the handling of parts, but inevitably, a few defective items do occur. The defect in this case was a chip on the side of the substrate. During visual inspection, it was difficult to distinguish between the chipped area and the substrate pattern, making the inspection challenging. The goal was to supplement this difficulty with image recognition to inspect efficiently and accurately. 【Inspection Settings and Results】 Using the "Scratch Inspection" feature of EasyInspector, we inspected the chips on the side of the substrate. By tilting the substrate slightly, the chips became easier to see. When we set the detection sensitivity (luminance difference) to a strict level (10), we were able to detect the chipped area, but the substrate pattern was also detected. After further inspection, we loosened the detection sensitivity (to 20), which successfully allowed us to detect only the chips without detecting the substrate pattern. 【Software and Equipment Used】 Software Used: EasyInspector310 Minimum Size of Inspection Target: Approximately 3-5mm Number of Inspection Points: 4 Camera Resolution: EI-Scan Current inspections can be performed with the 'EasyInspector2' color package [Scratch and Object Detection].

The metal parts used by automobile manufacturers may sometimes be shipped with defects such as dents or black spots, but if the dimensions are incorrect, it is pointless. This led us to use our software to inspect those dimensions. 【Inspection Settings and Results】 Using the "Dimension Angle Inspection" feature of EasyInspector, we measured three different areas with varying lengths. First, to clearly define the edges, we used backlighting; however, when the inspection object was placed directly on the backlight, the light reflected irregularly, causing the edges to appear blurred. Therefore, we took the photos at a distance of about 40mm from the backlight, placing the object on a glass surface. Since the inspection object appeared dark, we detected the bright and dark areas from top to bottom to measure the dimensions.

It is common in any industry to manufacture seemingly similar products on a single line. Even in audio equipment manufacturing, there have been incidents where the rear display of Blu-ray recorders of the same shape was mistakenly swapped, or defects occurred where the printing was smudged and unreadable. 【Inspection Settings and Results】 By using EasyInspector's "Comparison with Master Image" function, we were able to detect six printing discrepancies and determine visually similar counterfeit products (different items) in 0.36 seconds. Since a printing deviation of approximately ±1mm is considered acceptable, it would be deemed unacceptable under the current inspection settings, necessitating some adjustments. For example, one could set the verification level to a larger value or set the deviation correction for each inspection frame to "automatic" to perform corrections at various points, while conducting separate dimensional angle inspections for positional deviations. 【Software and Equipment Used】 Software Used: EasyInspector310 Field of View: Approximately 200 x 130mm Minimum Size of Inspection Target: 2mm Number of Inspection Points: 6 Camera Resolution: 3 million pixels Lens Focal Length: 12mm Distance from Lens to Product: 280mm Lighting: Indoor fluorescent lights

Metal welded parts, such as automotive components, often have defects like bead misalignment, blowholes, and tears due to specification differences, which have been common inquiries for a long time. Previously, inspections were conducted using EasyInspector with fixed positioning, but with the inspection capabilities of DeepSky released in 2020, it has become easy to set up inspections without fixed positioning. 【Inspection Settings and Results】 The target areas to be detected were enclosed in frames and labeled by type. A total of 14 images were used as training data, consisting of 8 OK images and 6 NG images. The learning process was executed for 2,000 steps, and the graph converged in about 16 minutes. The time may vary depending on the specifications of the PC used. In this inspection, since we are detecting the defective areas that were trained, it was set so that if even one defect is detected, it would be considered NG (only OK when the count is from 0 to 0), allowing for the detection of welding defects.

In the manufacturing of metal press products such as automotive parts, there is often a process for attaching eyelets. This time, we will conduct inspections for the presence or absence of eyelets and rubber parts. We received good products and defective products that do not have all the parts attached. 【Inspection Settings and Results】 Using DeepSky's inspection function, we were able to classify good products and defective products without all the parts as negative by using them as teachers and marking random positions where eyelets are missing. It is set to pass only when the correct quantity of eyelets (and rubber parts) is detected. If even one eyelet is missing, it will be marked as negative due to quantity mismatch. If you want to check "which eyelet is missing," it is possible to use the area specification function, but for now, we conducted the inspection with settings to determine only OK or NG. The left image shows the work of enclosing the parts we want to teach, called "annotation." The right image is the detection frame image, where the numbers represent the AI's confidence level percentage, referred to as "recognition points."

We will verify whether we can detect "dents on the ball," "dents on the tapered section," and "indentations on the tapered section" based on a request from an industrial equipment manufacturer. By creating a striped pattern on the reflective part of the ball, it becomes easier to identify the dented areas due to the resulting step difference. 【Inspection Settings and Results】 We inspected 25 images, including 10 images of "dents on the ball," 5 images of "dents on the tapered section," 5 images of "indentations on the tapered section," and 5 images of "good products." Out of the 25 images, 22 were correctly identified as either good products or defective parts. The three images of "dents on the tapered section" could not be recognized as defective parts; however, considering that in actual operation, multiple shots (around 3 times) are expected to be taken during one full rotation, it does not necessarily mean that the defective parts that were not recognized in the verification will always go unrecognized.

This is a verification to distinguish the defects of "scratches," "bleeding," and "spots" on metal painted products at the request of an industrial machinery manufacturer. We decided to photograph and verify by changing the orientation and position of a single defective sample. 【Inspection Settings and Results】 This time, we were able to make judgments by creatively adjusting the lighting during photography. Due to the size of the coaxial illumination we own, we could not capture the entire workpiece, so we focused on the damaged areas for imaging. Normally, inspections are conducted by capturing a field of view approximately 1.5 times the size with appropriately sized coaxial illumination, but we believe that the detection accuracy will be equivalent to that of this case based on the size of the damaged areas. To improve detection accuracy, we can use photos of misjudgments as training images for further learning. The left image is the "annotation" used to set parameters by enclosing the defective areas we want to detect. The right image is the "frame" detecting defects after learning and parameter setting.

It seems that manufacturers are struggling with various defect detections for saw blades, just like with other metal products, including issues such as unprocessed areas, dents, compression marks, chips, and foreign objects. For image inspection of shiny metal workpieces, please contact our company. This time, we are detecting wear on saw blades based on a verification request from a trading company we have been dealing with for some time. 【Inspection Settings and Results】 The judgment was made based on the NG images provided. Although we were unable to make sufficient settings due to difficulties in comparing with good products, we were still able to make some judgments, though some were misjudged. We report this as one result. The images show the defective areas that were successfully detected, highlighted with a light blue frame. The numbers indicate the confidence percentage (number of recognition points) from the inspection software. 【Software Used】 Software used: DeepSky Learning Edition Number of inspection points: 1 location (finding the worn area from the entire screen)

We received a request for inspection of cast precision parts from a manufacturer of production equipment design and fabrication. "Porosity" has been a frequently inquired case for some time. With DeepSky, released in 2020, it is easy to set up, does not require fixed positioning, can detect various defects with unstable shapes, and is also skilled at detecting defects in glossy workpieces. We have reported numerous evaluations of "porosity" inspections. [Inspection Setup and Results] This time, since the size of the defects was small, we narrowed the field of view to about 50mm, and DeepSky was able to recognize it well. Even if the patterns of defects to be detected increase, it seems likely that detection can still be achieved as long as the field of view is set appropriately. Our inspection software is also helpful for detecting fine defects in precision parts. [Software Used] Software Used: DeepSky Learning Edition Field of View: 50 x 40mm Minimum Size of Inspection Target: 0.5mm Number of Inspection Points: 1 (finding porosity from the entire screen)

This is an inquiry from a manufacturer engaged in a wide variety of businesses, including iron gear processing, processing of irregular iron products, aluminum casting, aluminum processing, and assembly. I believe that many manufacturers, not just the customer in this inquiry, are still struggling with issues such as unprocessed materials, dents, pressure casting, and the detection of casting defects in aluminum cast products. Even if it is a work that was previously given up on, we welcome inquiries to our company. 【Inspection Settings and Results】 Using a software called DeepSky, which employs AI (Deep Learning), we were able to detect foreign objects in metal products. This software was released in 2020. By training the software on the areas we want to detect, it adjusts its own setting parameters and learns to recognize them. The image shows the detection frame, and the numbers indicate the AI's confidence level percentage and the "number of recognition points." 【Software Used】 Software used: DeepSky Learning Version Number of inspection points: 1 (to find foreign objects from the entire screen)

We received a request for evaluation from a manufacturer of production equipment. This pertains to the judgment of defects caused by metal chips adhering to the workpiece. The DeepSky system released in 2020 is known for its ease of setup, the elimination of the need for fixed positioning, its ability to detect various shapes of defects, and its proficiency in detecting defects in shiny metal products, leading to numerous evaluations of metal product inspections. 【Inspection Setup and Results】 To determine the "metal chips inside the workpiece's hole," we made adjustments to the lighting. We attempted an inspection that captures images inside the hole, and this time, the bottom of the hole was clearly visible, allowing for accurate judgment. The initial evaluation is a report on whether simple detection is possible; however, depending on the position and shape of the defects, there may be instances where detection is challenging. After our free evaluation, we would like customers to directly experience the accuracy and setup methods before implementation, so we kindly ask you to utilize our free demo unit lending service. 【Software Used】 Software Used: DeepSky Learning Edition Minimum Size of Inspection Target: 2mm Number of Inspection Points: 1 (finding defects from the entire screen) Lighting: Coaxial Illumination

We received an inspection request from a manufacturer of production equipment. The inspection is for determining the chipping of a metal product, specifically a "gear." They sent us images of 20 defective items and 5 acceptable items. For some workpieces that are difficult to send as samples, verification can sometimes be done through photographs. 【Inspection Settings and Results】 Using DeepSky's inspection function, we were able to accurately determine the chipping of the metal workpiece (gear). The process of setting up the areas to be detected by enclosing them in rectangles is called annotation; in this case, we only enclosed the defective parts for training. The images show the detection frames. The numbers indicate the AI's confidence level percentage (number of recognition points). If the number of recognition points is low or if there are misjudgments, further training can be conducted. DeepSky, released in 2020, is easy to set up, does not require fixed positioning, can detect various types of defects in shapes, and is particularly good at detecting defects in shiny workpieces like metal products. We have reported numerous evaluations of metal product inspections. 【Software Used】 Software Used: DeepSky Learning Version Number of Inspection Points: 1 (detecting defects from the entire screen)
