Description

technical field [0001] The invention relates to the technical field of automatic assembly of motors, in particular to a device for detecting the number of wave gaskets by using force and displacement. Background technique [0002] With the rise of new energy vehicles, the application of motors is becoming more and more widespread. In the design of motors, many motors are equipped with wave gaskets to prevent axial movement of the rotor. Therefore, during the motor assembly process, the wave gasket Quantity testing is extremely important. [0003] At present, many products that are loaded with wave gaskets and need to detect the number of wave gaskets, because the automatic uploading of wave gaskets is difficult and costly, most of them are uploaded manually at present, due to human uncontrollable factors and wave gaskets It is stamped and formed, and there will be burrs and oil stains around it, making it easy to stack the wave gaskets together. In addition, due to the posi...

[0003] At present, many products that are loaded with wave gaskets and need to detect the number of wave gaskets, because the automatic uploading of wave gaskets is difficult and costly, most of them are uploaded manually at present, due to human uncontrollable factors and wave gaskets It is stamped and formed, and there will be burrs and oil stains around it, making it easy to stack the wave gaskets together. In addition, because of the position requirements and process requirements of the wave gaskets in product assembly, conventional vision cameras and distance sensors cannot be completed at all. Therefore, it is necessary to develop a simple, stable and applicable device that uses force and displacement to detect the number of wave gaskets

[0004] Because the wave gasket needs to be placed in the groove of the product, the traditional visual camera can only be detected directly above the groove, so that only the presence or absence of the wave gasket can be judged, and the specific quantity cannot be identified at all.

It is impossible to accurately judge the exact number of wave gaskets by using a separate distance sensor. The main reason is the size difference between the peak and trough of the wave gasket itself, the height tolerance of the gasket itself, and the randomness of the circumferential direction during the placement process. therefore cannot detect
