Description

Technical Field

[0001] The present invention specifically relates to the technical field of stator assembly, in particular to a motor stator assembly production line. Background Art

[0002] With the continuous advancement of science and technology, motors are being used more and more widely in various fields, such as new energy vehicles, industrial automation, and home appliances. The demand for motors in various industries continues to increase, and at the same time, higher requirements are being placed on the performance, quality, and production efficiency of motors. When assembling existing motor stators, smaller stators are usually assembled manually, which easily causes friction between the stator and the housing during the assembly process, and cannot effectively ensure the assembly precision between the stator and the housing, but instead affects the service life of the motor. At present, when assembling larger motor stators, semi-automatic devices are used for assembly, which also requires manual assistance and cannot effectively meet the requirements of large-scale and high-quality production. After searching, Chinese patent publication number CN202010687830.1 discloses a fully automatic motor stator assembly production line; it includes a frame, a carrier plate for carrying a motor housing and a motor stator is slidably connected to the frame, a positioning core shaft for fixing the motor stator is plugged into the carrier plate, and a driving assembly for driving the carrier plate to move is also connected to the frame, and a pre-shaping assembly for pre-shaping the copper wire and the connector of the motor stator, a wire cutting assembly for cutting off excess copper wire, a welding assembly for welding the copper wire and the connector, a core pulling assembly for pulling the positioning core shaft out of the motor stator, a heating assembly for heating the motor housing, a gluing assembly for gluing the motor housing, and an assembly assembly for inserting the motor stator into the motor housing and installing the motor housing and the motor stator together are sequentially arranged in the sliding direction of the carrier plate; the pre-shaping assembly, the wire cutting assembly, the welding assembly, the core pulling assembly, the heating assembly, the gluing assembly and the assembly assembly are all connected to the frame; Although the device in the above patent can effectively achieve the assembly effect when assembling the stator and the housing, the stator and the housing cannot be independently positioned during assembly.

In addition, when placing the housing and the stator, they are placed manually, and manual handling of the large-scale stator and housing is time-consuming and laborious. Summary of the Invention
