Description

Technical Field

[0001] This application relates to the field of motor processing equipment, and particularly to a pin inserting machine for motor winding skeletons. Background Art

[0002] A pin inserting machine for motor winding skeletons is an automated device dedicated to the motor manufacturing industry, mainly used for inserting pins (PINs) or pin feet into motor winding skeletons to complete the assembly and connection of motors.

[0003] The utility model patent with the authorization publication number CN213151854U discloses a full-automatic pin inserting machine for motor winding skeletons, including a frame, a skeleton conveying mechanism, a pin supply and processing unit, and a detection mechanism. The skeleton conveying mechanism is arranged above the frame and conveys the skeletons from one side of the frame to the other side. The pin supply and processing unit is located above the skeleton conveying mechanism. The pin supply and processing unit is used to process the pin wires from top to bottom and convey them to the skeletons that need to be inserted with pins on the skeleton conveying mechanism below, and is a unit for straightening, cutting, and marking the pin wires. At a position on the skeleton moving assembly line, on the right side of the pin supply and processing unit and not reaching the end port of the skeleton moving assembly line, there is a detection mechanism for detecting the skeletons that have completed pin insertion. Such a structural setting realizes a series of operations such as automatic needle feeding, pin insertion, marking, needle cutting, and product qualification detection for the skeletons, thereby improving the production efficiency of the skeletons and reducing the production cost.

[0004] However, in this structure, when inserting pins, the pin wires are inserted into the front end positions of the skeletons one by one. During the insertion process, the positions of the pin wires remain unchanged, while the distribution of the skeletons on the conveying device may be uneven, resulting in deviation of the insertion positions and a low qualification rate. When the conveyor belt runs for a period of time, it needs to be adjusted in a timely manner to avoid greater errors. Utility Model Content
