Description

A motor winding skeleton automatic pin insertion device and its detection system

technical field

The invention belongs to the technical field of motors, and in particular relates to an automatic pin insertion device for a winding skeleton of a motor and a detection system thereof.

Background technique

The motor winding skeleton is mainly composed of pins and the skeleton body. The shape of this motor winding skeleton usually presents an arc structure, and then coils are wound on the outside of it and located on the outside of the motor. Generally, the skeleton body is made of plastic, and the pins are made of metal. In the current processing, a single pin is inserted into the skeleton body, and the pins are inserted into the skeleton body one by one.

The Chinese patent application number CN202022354679.8 discloses a fully automatic motor winding skeleton pin insertion machine, which includes a frame, a skeleton conveying mechanism, a pin supply processing unit, and a detection mechanism. The pin supply processing unit is used for inserting the pins. The needle thread is processed from top to bottom and sent to the skeleton that needs to be inserted into the lower skeleton conveying mechanism. In this structure, the needle thread is inserted into the front end of the skeleton one by one when the needle is inserted. Due to the position of the needle thread during the insertion process It is always the same, and the skeleton moves with the conveying device at the bottom. Due to the deviation of the conveying device itself, the position of the pins is deviated, that is, the distance between the two groups of pins on the same product is quite different, and the pass rate is higher. Low, when the conveyor belt runs for a period of time, it needs to be adjusted in time to avoid greater errors.
