Description

Technical Field

[0001] The utility model relates to the technical field of new energy motor production, in particular to a buffer mechanism with a turnover function for a new type of straight section. Background Technique

[0002] In the manufacturing process of traditional hair-pin motors, before the flat copper wire is formed, it needs to pass through a hair-pin forming machine. After the production of the straight section is completed, a set of transfer devices are required to transport the copper wire to the forming device respectively, and a set of turnover devices to turn over the copper wire. This production process has the following characteristics of background technology: multi-step operation: the copper wire needs to go through multiple steps from straight section production to forming, including transportation and turnover. These steps are usually carried out separately, and the transportation and turnover actions are usually independently completed by different devices. Since transportation and turnover cannot be carried out synchronously, the copper wire needs to be transferred between different devices during the production process, resulting in a long beat time and thus increasing the production cycle time. Due to the separation of transportation and turnover actions, the production efficiency is limited. Especially under high production volume requirements, this separated operation may lead to production bottlenecks; and during transportation and turnover, the copper wire may be damaged or deformed, affecting the quality of the final formed product; in addition, traditional transportation and turnover devices usually require additional space, thus restricting the compactness of the production line and the space utilization efficiency, and at the same time resulting in an insufficiently optimized production process.
