[0002] The stator is a major part of the motor. It usually contains a set of coils that generate a magnetic field when the motor is running. The lamination refers to the construction method of the stator core, which is composed of many thin iron sheets stacked together. It can reduce eddy current losses and improve the efficiency of the motor. During the production process, the stator laminations need to be inspected to improve the quality of the product.

[0003] Existing stator lamination detection devices, such as a stator lamination detection device disclosed in application number CN202221809658.3, can realize synchronous movement of multiple moving blocks through an adjustment component, facilitate the horizontal detection component on the moving block to detect the stator laminations, facilitate position detection of multiple stator laminations, and facilitate detection of whether the edges of multiple stator laminations are neat; the vertical detection component can facilitate the adjustment of the height of the stator laminations, facilitate detection of whether multiple stator laminations are horizontal, and facilitate use.
