With the development of surface mount technology, mounting precision and working efficiency of electronic component mounting equipment are everincreasing. However, the attached object is relatively simple. The extension of the object scope of the device is one of the hot issues in the surface mount industry. In view of this demand, this paper designs a parallel clamping type stick plug. This paper discusses the working principle and structure of the plug. The dynamic model of the plug clamping mechanism was established, and the dynamic simulation was carried out. The simulation results were ve...
