Background In the production of computer power modules, it is a critical process to precisely assemble the power module assembly (e.g., a module with a PCB board) into the internal slot of the power housing. The traditional assembly mode mostly adopts rigid press fitting or simple pneumatic manipulator clamping and positioning. However, as power supply products are advanced toward high integration and miniaturization, the precision of the fitting between the internal slot and the connector is more and more required, and there is often a tolerance stack-up between the component and the housing. When the existing automatic assembly equipment processes such precise plug-in mounting, the following technical problems mainly exist: 1. in the rigid press fitting process, due to inaccurate positioning or tolerance accumulation, the connector is easy to insert obliquely, block or damage pins, and the product is scrapped; 2. The final compression confirmation of the connector in place is lacking in the assembly process, so that the phenomenon of virtual insertion or rebound easily occurs, and the reliability of electrical connection is affected; 3. the slots cannot be pretreated before assembly, and in the long-term use process, the connection parts are easy to cause poor contact due to oxidation or fretting wear.
