[0002] With the rapid development of the assembly and manufacturing industries and the continuous improvement of living standards, people's expectations for product quality are constantly increasing, placing higher demands on processed and assembled products. Traditional methods of assembling connecting plates rely primarily on manual assembly. Because connecting plates are plastic parts with internal snaps, assembly efficiency is low, quality consistency is poor, and even connecting plates may be damaged. There is no convenient and reliable dedicated assembly equipment to meet market demands. Therefore, the development of a professional assembly mechanism that is simple to operate, highly efficient, and provides stable quality is urgent. Summary of the Invention
[0003] The present invention proposes a block motor stator connecting plate assembly mechanism, which aims to solve the problems of low efficiency, poor quality consistency, and easy damage of products in the above-mentioned prior art. A block motor stator connecting plate assembly mechanism is proposed, which has the characteristics of simple and safe operation, high efficiency, high quality and stability.
