This is a non-contact density measurement sensor using microwaves. Microwaves are electromagnetic waves with frequencies ranging from 3 to 30 GHz, characterized by strong directivity and the ability to penetrate materials. When passing through a material, a phase change occurs depending on the physical properties of that material. Utilizing this characteristic, we have developed a sensor that measures the density and mass of objects non-contactly. The object to be inspected is passed through the opening in the center of the sensor, and the phase of the microwaves corresponding to its physical properties is measured. In areas where the density or mass differs, a change in phase occurs. We capture this phase change to perform measurements. Potential applications include measuring the density and mass of granular products such as supplements, and adapting to defect inspection of extruded products (such as tubes). If you have products that undergo destructive sampling tests, please feel free to consult us first. 【Features】 ■ Non-destructive, non-contact density measurement ■ High-speed processing with 1,000 points per minute sampling

This is a sensor that measures distortion using a uniquely developed MR method (Mesh Reflection). It projects slit illumination onto the measurement target and calculates curvature from the amount of distortion in the illumination. This method allows for high-precision measurement compared to pattern projection-type 3D measurement devices, as it amplifies distortion using the principle of optical leverage. 【AI that finds "something different"】 We have now made it possible to add AI judgment functionality. This AI learns the range of acceptable data from a small amount of OK data and determines anything outside the learned range as NG. Generally, AI needs to learn both OK and NG data. However, in factory production lines, the occurrence of NG is infrequent, and it takes time to accumulate sufficient NG data. On the other hand, our AI can learn with just a small amount of OK data, allowing for immediate operation right after the equipment is introduced. Additionally, as it operates for a while, NG data will accumulate. Our AI model is also equipped to learn from this NG data, enabling further improvements in detection accuracy.

This is a proposal case that achieves productivity improvement and labor reduction by automating a series of processes in the shipping and packing operations at the factory, from cardboard manufacturing, product picking, and packing to label application and sorting and stacking of cardboard. By combining robots, vision systems, and barcode readers, significant efficiency gains can be realized through optimal control. The current process requires a lot of manual labor, and there have been instances of sorting errors and the heavy labor of transporting packed cardboard boxes. Each line has three operators stationed to perform all tasks from cardboard assembly to stacking on shipping pallets manually, which occasionally leads to human errors. By automating this series of tasks, we can minimize the human involvement until shipping and reduce human errors. Furthermore, we can also build a data management system that can comprehensively manage everything from receiving to traceability, production, and shipping. We will provide an initial proposal for such automation within two weeks of receiving your inquiry.

This is an automatic inspection system that embodies the customer's desire for a compact device capable of conducting a full inspection of multiple inspection items that were previously performed manually, quickly and with simple operations. We adopted an indexing method where the workpiece is set on a rotary table and progresses through each inspection process. By setting the workpiece on a rotary indexing table and advancing through the processes, we minimized the picking of workpieces and achieved high-speed transfer to subsequent processes, while keeping the device size compact. The operability is designed so that after setting the workpiece, inspection can be started simply by blocking the sensor, creating a user-friendly interface for operators. The process that previously required multiple operators to perform several inspection items is now streamlined to just one operator setting the workpiece, contributing to cost reduction. Since inspection errors are eliminated regardless of operator fatigue or skill level, quality is guaranteed through full inspection, leading to improved evaluations from clients and increased sales. Additionally, the ability to conduct high-speed inspections at 1,200 units per hour has contributed to increased productivity and improved profitability. The automatic visual inspection device for micro electronic parts, born from these customer requests, can be viewed in the video below.

The "Surface Distortion Scanning Sensor STRIPER" from Hachiko Automation Co., Ltd. calculates curvature from the amount of change (displacement) in the stripe pattern and measures/evaluates the distortion of the object's surface. Why "curvature" instead of "displacement"? When trying to evaluate micro-distortion of a few micrometers as "displacement," it becomes buried within the displacement of the measurement surface, making it difficult to distinguish and extract the distorted areas. When evaluating micro-distortion as "curvature," the gentle changes and slopes of the measurement surface result in a large curvature radius, making the curvature almost "0," while the distorted areas have a small curvature radius, leading to significant changes in curvature that are easy to distinguish.

During the painting process of the product, there are rare occasions when the surface of the paint exhibits strong orange peel, resulting in appearance defects, so we would like to evaluate the orange peel in real-time during painting. In such cases, the surface distortion scanning sensor 'SPHYRNA' can be applied to evaluate the 'orange peel.' The phenomenon where the paint surface becomes uneven like the surface of an orange is referred to as 'orange peel.' The surface distortion scanning sensor 'SPHYRNA' inspects the minute unevenness of the object's surface, and by utilizing the 'tilt' data generated during the measurement process, it is possible to evaluate the degree of orange peel.

For example, if you want to inspect products with textured patterns like fiber sheets (geometric patterns) for scratches or foreign substances, even if you take pictures of the defective areas with a general visible light camera, the defects can be buried within the complex texture patterns, making it difficult to extract just the defects. Additionally, defects such as bubbles that occur inside the product cannot be seen with a visible light camera because they are internal. In such cases, by using a camera with a special imaging method, it is possible to visualize defects buried within patterns that were previously not visible and defects inside the product.

We propose a reading system for cast characters, mold characters, and engraved characters using a 2D laser displacement meter. 【Current Situation】 The embossed characters, such as part numbers on cast products, are the same color as the background, and there may be protrusions around the characters or the characters may be engraved on curved surfaces, making it difficult to cut out the characters. Standard optical systems cannot read these characters. 【Proposal】 "Embossed Character Recognition System Using 2D Laser Displacement Meter" By stably extracting embossed characters through 3D measurement that traces the surface shape of the object, we achieve a high character reading rate. Additionally, it supports inline measurement without contact. For more details, please refer to the catalog or feel free to contact us.

This device is an automatic wire processing machine that combines commercially available devices. Originally, it consists of two types of commercially available devices, the "mark tube printer" and the "wire cutter," which are from different manufacturers. By automating the transfer section of the mark tube, it operates like a single "automatic wire processing machine." Although there is only a slight clearance between the mark tube and the wire, we have achieved the automation of delicate tasks by utilizing our control technology. With the operation of the automatic wire processing machine, operators can engage in other higher value-added tasks, and since the automatic device works continuously even at night, work efficiency is significantly improved.
