[0031] In order to facilitate the person skilled in the art to understand the working principle of the embodiment of the present scheme, the working principle of the embodiment of the present scheme is described in combination with a specific application scenario:

[0032] After the brake pad is hot formed, cooled and washed, it will be stored in the area to be polished. When the brake pad needs to be polished and grooved, the conveying mechanism 2 can be started to place the brake pad in the bearing groove 302 one by one. The bearing groove 302 limits the brake pad, and the rear transmission belt assembly 201 moves to drive the bearing plate 301 and the brake pad to move.
