Description

Technical Field

[0001] The invention relates to the field of automobile brake pad processing, in particular to an environmentally friendly automobile brake pad surface spraying equipment. Background Art

[0002] With the increasing global awareness of environmental protection, the automotive industry is facing huge challenges and opportunities. The traditional automobile brake pad surface painting process is often accompanied by a large amount of volatile organic compound emissions, which causes serious pollution to the environment. Therefore, the development and application of environmentally friendly automobile brake pad surface painting equipment has become an urgent need in the industry. As an important part of the automobile safety system, the surface painting process of automobile brake pads has special requirements. On the one hand, the paint layer needs to have good adhesion and wear resistance to ensure that the brake pads will not fall off or wear due to friction during use; on the other hand, the paint layer also needs to have certain anti-corrosion properties to extend the service life of the brake pads. In the current automobile brake pad painting process, the brake pad is usually placed on a bracket. Subsequently, the side of the brake pad is automatically painted through an inclined nozzle. Since the brake pad is placed flat on the bracket, its side is perpendicular to the bracket. When the inclined nozzle is used to spray paint the side of the brake pad, the angle between the nozzle's spray trajectory and the side of the brake pad is small, so the nozzle can only operate in an oblique spraying manner, which makes it difficult for the sprayed paint to adhere evenly to the side of the brake pad, thereby affecting the painting quality of the brake pad to a certain extent. Summary of the invention

The sealing plate 2 42 moves away from the manifold 29 due to the air pressure difference, which makes the originally inhaled gas and the escaped paint particles enter the recovery box 32 through the gap between the sealing plate 2 42 and the enclosure plate 2 37, thereby completing the paint recovery operation. ;

[0031] Working principle: before the painting process, the door panel at the front end of the paint spray box 1 is opened, and then the brake pad to be painted is placed on the top of the rotating block 16, and the friction block at the bottom of the brake pad is located in the groove at the top of the rotating block 16, and then the door panel is closed; the external controller controls the motor 3 to run, and the motor 3 drives the gear ring 6 to rotate through the gear 4, and the gear ring 6 drives the mounting frame 7, the sliding rod 8, the vertical rod 9 and the top block 10 to move. Since the vertical rod 9 is slidably arranged on the inner side of the limit ring 11, this makes the vertical rod 9 and the top block 10 move along the trajectory of the limit ring 11 while following the movement of the gear ring 6; when the top block 10 When the top block 10 moves along the track of the limiting ring 11 to the bottom side of the storage plate 15, one side of the storage plate 15 will be lifted up, which increases the angle between the spray track of the nozzle 46 and the side of the brake pad, thereby switching the spray mode of the nozzle 46 from oblique spraying to a near-direct spraying mode. The near-direct spraying mode after switching is more convenient for the paint to adhere evenly to the side of the brake pad. In addition, the top block 10 that moves cyclically along the limiting ring 11 can lift the storage plate 15 from multiple angles, and then cooperate with the rotating nozzle 46 to perform the same spraying operation on multiple groups of brake pads on the storage plate 15, which enhances the spraying effect of the brake pad to a certain extent.

[0033] In addition, when the top block 10 lifts up one side of the storage plate 15, the abutment rod 17 located at the bottom of the lifted side of the storage plate 15 moves upward under the action of the abutment spring 19, and the volume of the enclosed space surrounded by the corresponding abutment rod 17, sealing plate 1 39 and sealing plate 2 42 increases due to the upward movement of the abutment rod 17. The set sealing plate 1 39 moves in the direction away from the collecting pipe 29 due to the effect of the air pressure difference, which makes the gas in the internal space of the paint spray box 1 and the escaped paint particles pass through the air hole 1 26, the air hole 27, the air hole 3 28 and the pipe 1 12 in turn into the inner cavity of the collecting pipe 29, and then enter the inner cavity of the return pipe 30 through the gap between the collecting pipe 29 and the sealing plate 1 39 and the enclosure plate 2 37. In the space surrounded by the middle abutment rod 17, sealing plate one 39 and sealing plate two 42; when the top block 10 moves out of the bottom of the storage plate 15, the storage plate 15 is restored to a horizontal state under the action of a plurality of abutment rods 17 and abutment springs 19, and the corresponding abutment rod 17 that originally moved upward is simultaneously moved downward, which increases and decreases the volume of the enclosed space surrounded by the abutment rod 17, sealing plate one 39 and sealing plate two 42, and the sealing plate two 42 moves away from the collecting pipe 29 due to the air pressure difference, which allows the originally inhaled gas and the escaped paint particles to enter the recovery box 32 through the gap between the sealing plate two 42 and the enclosure plate two 37, thereby completing the paint recovery operation and reducing the loss of raw materials.
