Abstract: Aiming at the problems of the padlocks assembly may failed because lacking pins or using wrong pins in manual assembly, the research was applied on the pins assembling processing including separating, direction selecting and sorting. An automatic separating and direction selecting feeding device for padlocks pins assembly was designed for the pins assembly. This device was mainly divided into separation mechanism, the direction selection mechanism and the sorting mechanism. The characteristic of the pins were used in the structure design of the device, and the PLC was used in the control system of the device. Last, the device was used in the factory to verify stability and feasibility. The results indicate that this device can completely replace the pins separating, direction selecting and sorting artificially which making the efficiency of pins assembly increase by about 33% and the error rate reduce by about 73%. This device provides adequate preparation for padlocks pins assembly in the padlock assembly.
