AI Technical Summary
In existing technologies, during the automated loading and unloading process of power module intermediate testing, the basket is placed backwards due to incorrect orientation identification by manual identification, which leads to test failures and equipment downtime, and also wastes time.
The system employs a coordinated approach between sensors and the basket structure. By installing multiple sensors on the conveyor belt device, the system automatically detects and determines the placement direction of the basket. These sensors include a first sensor, a second sensor, and a third sensor, which perform multiple detections at the loading end, the middle section, and the unloading end to ensure the correct basket orientation.
It significantly improves the accuracy and reliability of testing, reduces test failures and equipment downtime caused by incorrect orientation, and improves testing efficiency and production automation.
