Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, and in particular to a spraying equipment for brake pad coating of automotive braking systems. Background Technology

[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks withstand external pressure, generating friction to slow the vehicle down. Automotive brake pads generally consist of a steel plate, an adhesive heat-insulating layer, and friction blocks. The steel plate is coated to prevent rust.

[0003] During the backplate painting process, care must be taken to avoid painting the friction blocks, as the paint is applied to the contact surface between the friction blocks and the brake disc; otherwise, a safety hazard may occur. The backplate painting also serves a rust-preventing function, so the sides of the backplate also need to be painted. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a brake pad coating spraying device for automotive braking systems, comprising a support frame. Conveyor rollers are rotatably mounted on both sides of the upper end of the support frame. Several conveyor belts are wound around the conveyor rollers. Paint tubes are arranged side-by-side above the center of each conveyor belt. Several nozzles are evenly spaced on each paint tube, with the nozzles on two paint tubes angled downwards at a 90° angle. When brake pads are placed on the conveyor belts, they are conveyed by the conveyor table, passing under the nozzles, and their back surfaces are sprayed with paint. The angled nozzles ensure that the sidewalls of the backing plate can also be sprayed.

[0005] The equipment also includes a fixing fixture, which comprises a rod with several fixing holes evenly spaced on the rod. These fixing holes are fan-shaped and are used to fit and fix the friction pads of the brake pads. Because the brake pads are relatively small and it is necessary to prevent them from being painted, the fixing fixture is provided. This ensures that the brake pads are evenly distributed on the fixture, allowing for batch painting and ensuring a neat arrangement of the brake pads.

[0006] Preferably, a cuboid paint container is positioned above the support, and a conveyor belt passes through the paint container, which is fixedly connected to the support. Furthermore, the nozzle is located inside the paint container, preventing paint from dispersing into the air during the spraying process and reducing air pollution.

[0007] Preferably, an exhaust pipe is fixedly connected to the upper end of the paint spray container, and a fan is fixedly connected inside the exhaust pipe. When the fan is turned on, a negative pressure is generated in the paint spray container, which then draws out the diffused paint. It is important to control the magnitude of the negative pressure in the paint spray container to avoid affecting the quality of the paint spraying during the suction process.

[0008] Preferably, a plurality of limiting rods are fixedly connected at equal intervals to the outer side of the conveyor belt on the conveyor roller. Each rod has a limiting hole at both ends, and the limiting holes and limiting rods cooperate with each other. The limiting rods and limiting holes ensure that the fixture is fixed, guaranteeing that the brake pads are secured during conveyor belt operation, which facilitates uniform painting.

[0009] Preferably, a paint container is disposed below the bracket, and a pump is disposed inside the paint container, with the pump's output end fixedly connected to a paint pipe. When the pump operates, it draws paint from the paint container and delivers it through a nozzle, thereby realizing the spraying operation.

[0010] Preferably, a drive motor is fixedly connected to the bracket, and the output end of the drive motor is fixedly connected to the end of one of the conveyor rollers. When the drive motor is started, the conveyor roller rotates, thereby realizing the operation of the conveyor belt.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. A fixed fixture is provided to neatly fix the brake pads on it, while the friction block is fastened in the fixing hole. This not only achieves fixation but also covers the friction block, preventing paint from being sprayed onto it. In addition, the fixed fixture allows for batch painting, which is convenient for transfer and then drying / baking the paint.

[0013] 2. It is equipped with two sets of nozzles, and the two sets of nozzles are tilted at an angle of 90° to ensure that the edges on the back side can also be sprayed, thus ensuring the quality of the spraying. Attached Figure Description

[0021] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figures 1 to 4 As shown, a brake pad coating spraying device for an automotive braking system includes a support 1, which includes several vertical and horizontal bars. Conveyor rollers 2 are rotatably mounted on both sides of the upper end of the support 1. Several conveyor belts 3 are wound around the conveyor rollers 2, and are evenly spaced. Paint tubes 10 are arranged side-by-side above the middle of the conveyor belts 3, and several nozzles 12 are evenly spaced on the paint tubes 10. The nozzles 12 deliver paint to spray onto the surface of the brake pads. The nozzles 12 on the two paint tubes 10 are inclined downwards at an angle of 90°. This device is used to improve the rust resistance of the brake pad backing plate; therefore, the sides of the backing plate also need to be sprayed. If the nozzles are vertically downwards, the spraying effect on the sides will be poor. Here, the inclined nozzles 12 are used to ensure that the sides of the backing plate can also be sprayed.

[0023] The equipment also includes a fixing fixture 7, which is used to support and fix the brake pads to achieve batch spraying. The fixing fixture 7 includes a rod 71, on which a number of fixing holes 73 are set at equal intervals. The fixing holes 73 are fan-shaped and fit and fix the friction pads of the brake pads. That is, the friction pads are fastened in the fixing holes 73, which not only fixes the brake pads, but also shields the friction blocks to prevent them from being sprayed with paint and causing safety hazards.

[0024] A rectangular paint container 4 is installed above the support 1, and the nozzle 12 is also housed in the paint container 4 to reduce paint leakage and pollution. The conveyor belt 3 located above passes through the paint container 4, and the paint container 4 is fixedly connected to the support 1. Specifically, a connector is provided between the paint container 4 and the support 1 to achieve a fixed connection between the two.

[0025] An exhaust pipe 5 is fixedly connected to the upper end of the paint spray container 4. The exhaust pipe 5 draws out the air from the paint spray container 4. A fan 6 is fixedly connected inside the exhaust pipe 5. When the fan 6 is turned on, a negative pressure is generated inside the paint spray container 4, which extracts the gas inside the paint spray container 4. It is important to control the magnitude of the negative pressure in the paint spray container 4 to avoid the negative pressure affecting the quality of the spraying.

[0026] Several limiting rods 8 are fixedly connected at equal intervals to the outer side of the conveyor belt 3 on the conveyor roller 2. Both ends of the rod 71 are provided with limiting holes 72, and the limiting holes 72 and the limiting rods 8 cooperate to fix the fixing fixture 7 on the conveyor belt 3.

[0027] A paint container 9 is provided below the bracket 1. The paint container 9 is used to store paint. A pump is installed inside the paint container 9, and the output end of the pump is fixedly connected to the paint pipe 10. The pump tooling pumps the paint and then sends it out from the nozzle 12 to spray it onto the back plate.

[0028] A drive motor 11 is fixedly connected to the bracket 1. The output end of the drive motor 11 is fixedly connected to the end of one of the conveyor rollers 2. When the drive motor 11 is started, the conveyor roller 2 rotates, thereby the conveyor belt 3 runs and sends the brake pads to the bottom of the nozzle 12 for spraying.

[0029] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
