Description

Technical Field

[0001] The utility model relates to the technical field of stator welding, in particular to a stator wire welding fixture disassembly device. Background Art

[0002] Since the new X-Pin winding stator can achieve higher power density and electric drive efficiency, many domestic manufacturers have begun to study X-Pin winding technology. The core difficulty lies in how to shorten the solder joint height during Pin wire welding and how to avoid overheating and burns of the paint film by laser welding energy in a very small space. At the same time, sufficient welding strength must be maintained to ensure the reliability of the solder joint. Therefore, the positioning jig tooling during welding is particularly important. After positioning, welding production can be carried out accurately, and the positioning fixture needs to be removed after production. The positioning fixture is relatively heavy and the entire production line is produced. Therefore, a robotic arm or other disassembly equipment is needed to adapt to the rhythm production. Therefore, a special disassembly device is designed in combination with production needs to improve production efficiency. Utility Model Content

[0017] The present invention will be described below based on the embodiments in conjunction with the drawings in the embodiments of the present invention. However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.

[0018] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn to scale.

[0019] At the same time, unless the context clearly requires otherwise, words such as "include", "comprising" and the like throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, as "including but not limited to".
