DUPLODEC

Detects forgotten tightening of screws and forgotten attachment of parts during assembly. Achieves in-process inspection to prevent defects from flowing to the next process.

■ Do you have any of these troubles? - Forgetting to tighten screws or attach parts - Relying on visual inspections, leading to variations among workers - Discovering defects after assembly, resulting in rework and returns - Taking time to identify the cause of defects, with no evidence left - Wanting to maintain quality but lacking inspection man-hours and manpower The solution to these challenges is the "Assembly Inspection Device," which detects mistakes during the assembly process. The Assembly Inspection Device checks for the presence of parts, forgotten screw tightening, incorrect parts, and label application through image inspection, allowing for early detection of assembly mistakes. By conducting inspections during the assembly process rather than after completion, it reduces the need for rework and returns of defective products, contributing to improved efficiency and quality on the production line. Additionally, by saving images taken during inspections, it can be used as evidence of quality and for traceability. We will propose the optimal inspection methods and system configurations tailored to your assembly process and inspection requirements. *For more details, please feel free to contact us.

basic information

Main Features ■ Quality Improvement Early detection of assembly mistakes to prevent defective products from being released. By detecting the presence or absence of parts and forgotten screws during assembly, corrections can be made before defective products move to the next process. This achieves stable quality through in-process inspections, rather than relying solely on final inspections. ■ Cost Reduction Reduction of rework, redoing tasks, and waste loss. By discovering defects during the assembly process rather than after completion, rework such as disassembly and reassembly can be minimized. This leads to reductions in material costs and labor hours, contributing to lower manufacturing costs. ■ Productivity Improvement Smooth production without stopping the line. Problems can be identified and corrected on the spot, preventing troubles and line stoppages in subsequent processes. This supports stable operation of the production line without interrupting the flow of the assembly process. ■ Evidence and Traceability Saving inspection images to leave proof of quality. By saving images and inspection results during inspections, they can be utilized as quality records and traceability documents. In the event of a defect, this aids in cause tracking and quality certification. *Currently under development, please feel free to contact us for more details.

Applications/Examples of results

In the assembly process of electronic devices and mechanical parts, it addresses applications such as confirming the number of screws, checking the presence of parts, verifying connector connections, confirming label attachments, and checking the orientation of parts. By replacing processes that relied on visual inspection and operator judgment with image inspection, it prevents variations in inspection, achieves human error prevention, and stabilizes quality. It is compatible with both cell production and line production.
