An auto and motorcycle parts industrial park has introduced an intelligent inspection system, equipping its motorcycle main and countershaft production with "smart eyes." This system integrates machine vision, laser ranging, and other technologies to comprehensively inspect key indicators such as dimensional accuracy, tooth surface finish, and hardness of the main and countershafts. Inspection efficiency is increased by 5 times compared to manual inspection, and the inspection error is reduced to 0.005mm, effectively solving the problems of missed and false inspections in traditional manual inspection. Based on this, the production workshop has achieved closed-loop management of "inspection-feedback-adjustment." When a defective product is detected, the system can automatically trigger adjustments to production equipment parameters to ensure stable quality of subsequent products. Currently, the product qualification rate of the main and countershaft production line in the park has increased from 98.2% to 99.8%, and the production cycle has been shortened by 15%. The park's负责人 stated that the next step is to promote the deep integration of intelligent inspection technology with the entire production process, creating a benchmark base for intelligent production of motorcycle main and countershafts.
