[0002] The silicon steel sheet bidirectional positioning mechanism with anti-overflow glue is a device used for processing and positioning the core components of motors and transformers. This mechanism ensures that the silicon steel sheet maintains precise position and direction during processing through precise guide bearings, positioning pins, fixtures and adjustable mechanical structures. The anti-overflow glue forms a layer of glue on the edge or surface of the silicon steel sheet, controlling the magnetic flux density and reducing energy loss, thereby optimizing the performance of power equipment.

[0003] Since silicon steel sheets require high-precision positioning during the processing, the existing bidirectional positioning mechanism may not provide sufficient stability and accuracy, resulting in reduced processing accuracy or glue overflow. In addition, the existing mechanism design may be too complicated, resulting in difficulties in assembly and maintenance, while increasing production costs and time costs.

Therefore, according to the use requirements, a mechanism with a simple structure and easy operation is needed to perform bidirectional positioning of the silicon steel sheet and prevent glue overflow from the silicon steel sheet.
