Specifically, the magazine 5 of the present application is used for placing IPM modules, and multiple layers may be disposed on the magazine 5, and each layer may be used for placing an IPM module. During loading, the transfer jig 33 takes out the material from the magazine 5 layer by layer, the material taking is that the magazine 5 is moved up and down, so that the transfer jig 33 can obtain IPM modules on layers with different heights in the magazine 5.

In the use process of the IPM module detection device, the transfer fixture 33 sends the IPM module in the magazine 5 to the detection mechanism 2 for the image acquisition device 22 to shoot an image, so as to realize automatic detection of the IPM module. According to the detection device, the links of manual participation can be greatly reduced through automatic feeding, detection and material transfer processes, so that the production efficiency is remarkably improved. The automatic detection mode can run continuously and efficiently, is beneficial to shortening the production period of the IPM module and reducing the production cost. In addition, the detection device can accurately and rapidly identify and detect the IPM module through accurate mechanical control and image processing technology, automatic detection is realized, and error probability in the detection process is greatly reduced. The defect that the manual detection mode is easily influenced by human factors, such as fatigue, negligence and the like, and errors in the detection process are overcome.

The balls 322 reduce the direct contact of the module with the carrier 321, thereby reducing the risk of scratching or abrasion of the module surface and ensuring the quality and appearance of the module. Due to the reduction of friction resistance, the transfer jig 33 operates more smoothly when picking and placing the IPM module, which reduces jamming and delay and improves production efficiency.
