Description

Technical Field

[0001] The invention relates to the technical field of motor stator and rotor core manufacturing technology, and in particular to a motor stator and rotor stamping die set with a visual detection function. Background Art

[0002] The stator and rotor cores of the motor include the stator core and the rotor core, both of which are made of stacked silicon steel sheets (punching sheets). Silicon steel sheets are usually punched into loose sheets on a punch press using a stamping die set. In order to avoid stacking through tooling and manual arrangement, the stacking and fixing of loose sheets is performed by gluing in the prior art. The specific implementation method is to set a glue dispensing station on the stamping progressive die, and a glue dispensing device is set on the glue dispensing station. The glue dispensing device includes multiple glue supply nozzles. When the material strip passes through the glue dispensing station, glue is applied to one side of the material strip through the glue supply nozzle; when the material is dropped, the core punching sheet enters the tightening ring, and the two adjacent core punching sheets are fixed together by glue.

[0003] However, the above-mentioned prior art glue dispensing lamination technology still has some shortcomings. The first point is that the glue inlet channel and nozzle (glue dispensing outlet) on the glue dispensing device are easily blocked or contaminated during use. When cleaning after blockage or contamination, the device needs to be shut down and the entire device needs to be moved, which makes maintenance more troublesome and affects the efficiency of stamping production. The second point is that when dispensing glue on the iron core, there is a lack of a detection device for the glue points. If the nozzle part is blocked or the glue supply is insufficient, it is easy to cause uneven glue dispensing on the iron core, resulting in loose bonding of the iron core, affecting the assembly and use of the iron core, and to a certain extent affecting the magnetic properties of the iron core. Summary of the invention
