Based on workbench simulation to research the influence of different pin structures on the assembly of silicone rubber buttons and PCB

At present, one silicone rubber button and no pins nozzle structure that can be used for automatic sticking group have been developed, but the pin's structure of the silicone button greatly affects the success rate of the sticking group and the stability after the sticking group is completed. Therefore, it is very important to research the assembly process of silicone rubber buttons with different pin structures and PCB, which has great research significance. In this paper, we used Solidworks to create three silicone rubber buttons with conical, arc, and cylindrical node pin structures respectively, used workbench to simulate the process of button pins and PCB assembly. By comparing the pressure changes of different pin structures in the process of fitting and analyzing the influence of different pin structures on the assembly process. It is concluded that the arc node pin structure is more effective.
