Description

Technical Field

[0001] The utility model relates to the technical field of brake pad steel back processing, in particular to an automatic cleaning device for the steel back surface of a brake pad before spraying. Background Art

[0002] Brake pads are also called brake pads. In the car's braking system, brake pads are the most critical safety parts. The quality of all braking effects is determined by brake pads. After the brake pads are formed, they need to be sprayed with a coating. In order to improve the adhesion of the coating, the steel back of the brake pads needs to be cleaned.

[0003] Most of the existing brake pad steel backs are cleaned manually, which is too inefficient. Therefore, some people have come up with the idea of ​​designing a device that uses a motor to drive a brush to clean the steel back. For example, announcement number CN217748230U specifically discloses an automatic cleaning device for the steel back surface of a brake pad before spraying.

[0004] However, in actual use of the above-mentioned automatic cleaning device for the steel back surface before spraying of brake pads, people will find that the steel back is not restricted when the device is cleaning the steel back, which leads to the phenomenon that the steel back is easily displaced during the actual cleaning process, greatly reducing its cleaning effect.
