[0002] In the manufacturing process of brake pads, after the surface of the brake pads is polished by a grinder, the next step is to spray plastic powder on the steel back of the brake pads. This step involves spraying the plastic powder evenly on the back of the brake pads, followed by heating and curing to ensure that the plastic powder is firmly attached to the brake pads. In the prior art, when the brake pads are sprayed with powder, some plastic powder will remain on the conveying device, causing waste of plastic powder and affecting the operation of the conveying device. Therefore, it is necessary to use a brush to clean the plastic powder on it. However, after the brush is used for a long time, the plastic powder will remain on the brush, which reduces the subsequent cleaning effect of the brush. Therefore, the above problem needs to be solved. Summary of the invention

[0025] like Figure 1-8 As shown, the present invention provides a brake pad powder spraying treatment device, including a box body 1, an electrostatic spray gun 3, a conveying mechanism 2 and a cleaning mechanism 4, wherein the box body 1 is arranged on the conveying mechanism 2, and the electrostatic spray gun 3 is symmetrically arranged on the inner top wall of the box body 1, the conveying mechanism 2 is used to transport the brake pad to be powder sprayed, and the cleaning mechanism 4 is arranged on the side of the conveying mechanism 2 and is used to clean the conveyor belt 21 on the conveying mechanism 2.

[0026] It should be noted that the conveying mechanism 2 also includes a frame 422, a driving roller 23, a driven roller 24 and a right-angle motor 25. The two sides of the frame 422 are rotatably connected with the driving roller 23 and the driven roller 24 respectively. The driving roller 23 and the driven roller 24 are connected with the conveyor belt 21. The right-angle motor 25 is installed on the frame 422 and its output shaft is connected to the driving roller 23.

[0027] In addition, the cleaning mechanism 4 includes a brush 41, a sleeve 43, and a driving disk 44. The two ends of the brush 41 are rotatably connected to the fixed plates 42 on both sides of the frame 422, respectively. The sleeve 43 is sleeved on one end of the brush 41 and is rotatably connected to the fixed plate 42. The side of the sleeve 43 is symmetrically provided with a support plate 1 431 and a support plate 2 432. The side of the support plate 1 431 is vertically symmetrically provided with two levers 433. The lever 433 located on the upper side is provided with an elastic pressure plate 48. The elastic pressure plate 48 is an inverted "V"-shaped structure. When in contact with the conveyor belt 21, the elastic pressure plate 48 is deformed. , so that the plastic powder on the conveyor belt 21 is squeezed toward both sides to facilitate the shedding of the plastic powder. The driving disk 44 is arranged on the active roller 23 and is provided with a driving groove 441. The driving groove 441 includes an outer convex groove 442 and an inner groove 443. Two adjacent outer convex grooves 442 are connected through the inner groove 443. The driving groove 441 is provided to drive the lever 433 to reciprocate. The side of the support plate 432 is vertically provided with an insertion rod 434 inserted into the driving groove 441. The pulley 1 45 installed on the active roller 23 is connected to the pulley 2 47 installed on the brush 41 through a driving belt 46.

[0028] In addition, a material holding box 5 is provided on the outer side of the frame 422, so as to facilitate the collection and processing of the plastic powder that falls off.

[0029] Specific implementation and principle:

[0030] During operation, the brake pad to be powder-sprayed is placed on the conveyor belt 21, and the output shaft of the right-angle motor 25 of the conveying mechanism 2 drives the active roller 23 to rotate, so that the conveyor belt 21 rotates and drives the brake pad to move into the box 1, and the brake pad is powder-sprayed by two electrostatic spray guns 3 in the box 1. At the same time, the pulley 1 45 on the rotating active roller 23 drives the brush 41 and the pulley 2 47 to rotate through the driving belt 46, and the plastic powder remaining on the conveyor belt 21 is cleaned into the material box 5 by the rotating brush 41, and the active roller 2 The driving disc 44 on the 3 drives the support plate 2 432 to rotate through the driving groove 441 thereon, so that the sleeve 43 and the support plate 1 431 rotate, and the lever 433 on the side of the support plate 1 431 moves the brush 41 to shake off the plastic powder attached to the brush 41. When the elastic pressure plate 48 on the lever 433 contacts the conveyor belt 21, the plastic powder attached to the conveyor belt 21 is squeezed toward both sides, which accelerates the falling of the plastic powder and improves the cleaning effect of the conveyor belt 21. Finally, the brake pad after the powder spraying treatment is transferred to the next station by the industrial robot.

[0031] To summarize, in the present application, the brake pads to be powder-sprayed are transported to the box body 1 through the conveying mechanism 2, and the brake pads are powder-sprayed through the electrostatic spray gun 3. When the conveyor belt 21 rotates, the driving disk 44 is driven to rotate, and the driving slot 441 thereon drives the lever 433 to rotate. The plastic powder remaining on the conveyor belt 21 is pressed toward both sides by the elastic pressure plate 48 on the lever 433 to make the plastic powder fall off. At the same time, the conveyor belt 21 is brushed by the rotating brush 41 to make the plastic powder fall off. The lever 433 swings back and forth while moving the brush 41 to make the plastic powder remaining thereon fall off, thereby improving the cleaning effect of the brush 41.

[0032] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
