Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1: An automatic solder ball cleaning device for the surface of a soldering fixture, such as... Figures 1-4As shown, the assembly includes a conveyor belt 2 fixed on a workbench 1. A dust cover 3 is installed on the conveyor belt 2 to prevent solder balls from splashing and contaminating the environment, while also reducing external dust interference with the cleaning process. The dust cover 3 is equipped with a drive assembly and a cleaning assembly, and dust collection assemblies are located on both sides of the dust cover 3. The drive assembly includes a drive motor 4 and a drive roller 9. The drive motor 4 includes a front drive motor and a rear drive motor, both of which drive and connect to the drive roller 9. The drive roller 9 is located at the inlet of the dust cover 3 for stable clamping of the welding fixture. The drive roller 9 is made of rubber to protect the welding fixture. The cleaning assembly includes a cleaning motor 5 that drives a cleaning roller 10 to rotate. The dust collection assembly includes a duct 6 and a dust collection box 7. The duct 6 is connected to the dust collection box 7, and a fan is installed inside the duct 6. The duct 6 is connected to the interior of the dust cover 3.

[0023] Example 2: An automatic solder ball cleaning device for a welding fixture surface. The dust cover 3 has an inlet and an outlet. Guide plates 8 are provided on both sides of the inlet, arranged symmetrically in a V-shape to guide the welding fixture into the inlet of the dust cover 3. There are two front drive motors and two rear drive motors. The two front drive motors are located at the top of the inlet side of the dust cover 3, symmetrically arranged, and rotate in opposite directions. The two rear drive motors are located at the top of the outlet side of the dust cover 3, symmetrically arranged, but rotate in opposite directions.

[0024] The cleaning roller 10 is equipped with a brush made of nylon. The nylon brush combines cleaning power with surface protection to avoid scratching the fixture.

[0025] The dust cover 3 has through holes on both sides, through which the air duct 6 connects to the interior of the dust cover 3. Sealing rings are installed at the through holes to ensure efficient dust collection. There are six air ducts 6, symmetrically arranged on both sides of the dust cover 3, and each air duct 6 connects to the dust collection box 7.
