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.

Main Features ■ Quality Improvement Early detection of assembly errors 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, and waste loss. By discovering defects at intermediate stages rather than after assembly is complete, rework tasks 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 storing images and inspection results during inspections, they can be utilized as quality records and traceability materials. In the event of a defect, this aids in cause tracking and quality certification. *For more details, please feel free to contact us.
