Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, and more specifically to a stator terminal installation device. Background Art

[0002] The motor stator is a major component of the motor, usually composed of a stator core and windings. The stator core is made of laminated silicon steel sheets and is used to fix the windings and provide a magnetic circuit, while the windings are wound with insulated wires to generate an electromagnetic field. The terminal is the interface that connects the windings to the external circuit and is usually installed on one side of the stator.

[0003] The terminal is usually fixed on the stator by welding or crimping, and is used to connect the stator winding wires with external circuits, such as power lines, control lines, etc. The function of the terminal is to connect the stator winding with the external circuit so that the motor can work normally. Through the terminal, you can easily connect the power supply, control signal, etc. to start, stop and control the motor.

[0004] The existing stator terminal installation equipment still has the following problems: when installing terminals on the existing stator, a terminal insertion machine is often used to insert the terminals into the terminal slots respectively. However, in the actual production site, there may be dust, fine particles or other pollutants in the air. These substances will flow into the terminal insertion slots of the motor stator with the air flow. Dust and debris may also enter the terminal insertion slots due to improper operation or negligence of workers. The existing stator terminal installation equipment lacks certain dust removal components in the process of installing terminals for stators of various sizes. If these impurities are not cleaned in time, it may affect the insertion and contact of the terminals, thereby affecting the normal operation of the motor;

[0005] In addition, the existing stator terminal installation equipment often needs to cut the excess copper wire after the terminal is inserted, and the existing cutting knives are mostly fixed with bolts, which results in a lot of time spent every time the cutting knives need to be replaced, which not only reduces work efficiency, but also causes a great labor burden on personnel and brings many inconveniences to use.

[0006] In view of this, we propose a stator terminal installation device. Utility Model Content
