Description

Technical Field

[0001] The invention relates to the technical field of motor stators, and in particular to a stator lead surface grinding device. Background Art

[0002] In the field of new energy, the stator leads (leads are several lead wires of the stator winding) need to have their surface paint removed before welding. The paint removal is usually done by scraping the leads with a scraper to remove the paint layer.

[0003] The welding quality of stator lead wires is crucial to the performance and reliability of the product. After removing the paint, the lead surface cannot be 100% smooth due to many factors, such as burrs. In addition, since it takes a while to weld the lead wires after removing the paint layer, the lead wires are easily oxidized during storage, forming oxides and impurities. These pollutants will seriously affect the quality of the welded joints, resulting in reduced welding strength and increased welding defect rates.

[0004] Based on the above factors, the lead wires are usually polished before welding. The traditional method is manual polishing. Although manual polishing can remove some oxides, it is inefficient, inconsistent, and difficult to ensure the accuracy and depth of polishing. Therefore, the current task is to develop an efficient and automated polishing system, which is of great significance to improving the welding quality of new energy stator iron wires.
