New type fully automatic double-end terminal optimization research-precision

Terminals Hardware Terminals New fully automatic double-ended terminals / electrical connectors have been used more and more widely in the fields of electronics, aviation, aerospace and communications. Some electrical connectors in my country have reached the advanced level of developed countries. However, due to the late start of the domestic electrical connector industry, there is still a big gap between the processing technology of key parts of its processing equipment, the speed and stability of the equipment, and the advanced foreign technology. Even if the same type of electrical connector is produced, there is still a significant gap between the production efficiency and quality of the same type of electrical connector abroad. Therefore, a new type of efficient and stable automatic terminal crimping equipment is the demand of the mainstream domestic market in the future. In order to design an efficient and stable automatic terminal crimping equipment, the existing domestic fully automatic terminal crimping equipment (double-ended) was studied, and it was found that the cam transmission structure ensures the stability of the equipment, but the production capacity of the equipment is lower. The new equipment optimizes and integrates the actions of existing equipment, especially those that rely on mechanical cams to complete, and proposes a new action plan (changing swing to linear motion), which fundamentally improves efficiency. In terms of mechanical structure design, the straightening mechanism of the wire rod was studied, the advantages and disadvantages of the wire feeding and straightening mechanism of the existing equipment were analyzed, and a new type of wire feeding and straightening mechanism was designed for the purpose of ensuring the straightening effect and speed; The movement mechanism of the scrap cutting mechanism has made a dynamic selection for the new scrap cutting mechanism; the theory has proved the reason for the insufficient clamping force of the existing equipment, and a new design mechanism has been proposed; the working principle of the terminal intermittent feed has been analyzed and designed The corresponding mechanical mechanism. In the control system, the main power components required by the equipment were analyzed first, the distribution of I/O points and the selection of related PLC and servo motors were made, and the subroutines of each mechanism were designed. Based on the finite element analysis software ABAQUS, the process of crimping the terminal was simulated and analyzed, focusing on the impact of the various parameters of the stamping die (the height of the separation tip of the stamping die, the inclination angle, and the speed) on the terminal insulation crimping, and the stamping die with the best parameters was obtained. On this basis, the crimping mechanism of the equipment is optimized. Committed to becoming the world's most professional supplier of electronic stamping parts.
