AI Technical Summary

Technical Problem

Existing length testing equipment is greatly affected by product appearance and environment, resulting in limited testing accuracy, with a maximum of only 0.1mm or 0.05mm, and product compatibility is difficult to adjust.

Method used

It adopts a combination of end-face camera inspection mechanism, rotary wheel fixture, Xinhe grating ruler and PLC main control module. The drive motor drives the transmission pulley group to rotate the rotary wheel body. With the cooperation of multiple inspection cameras and light source board, it can realize multiple inspection data analysis and accurate compensation, and adapt to different product sizes.

Benefits of technology

It achieves a detection accuracy of 0.01mm, automatically adjusts to different product sizes, improves detection flexibility and accuracy, has strong adaptability, and high detection efficiency.
