Description

Technical Field

[0001] This invention belongs to the field of automotive brake spring impregnation technology, and in particular relates to a coating impregnation device for automotive brake springs. Background Technology

[0002] Automotive brake springs, also known as brake springs, are elastic elements installed on automotive brake pads and brake gears. Automotive brake springs are generally installed in automotive calipers to maintain the correct position of the brake pads within the calipers. Since the performance of the springs directly affects whether the automotive calipers can sensitively and quickly clamp the brake discs to decelerate the vehicle, the quality of automotive brake springs is particularly important.

[0003] Because automotive brake spring pads are prone to scratches and wear after long-term use, they suffer from poor impact resistance, short service life, and potential safety hazards. Therefore, a coating process is necessary. However, existing methods cannot coat the spring pads at the clamping points, resulting in incomplete coating coverage and requiring rework. This leads to low production efficiency and reduced quality. Summary of the Invention

[0004] In order to overcome the shortcomings of existing spring sheet coatings that result in incomplete coating, leading to low production efficiency and poor spring sheet quality, the purpose of this invention is to provide a coating impregnation device for automotive brake spring sheets that can achieve complete coating, high production efficiency, and good quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a coating impregnation device for automotive brake spring pads, comprising a reservoir, a feeding rack, and a cylinder. The feeding rack is connected to the reservoir, and the cylinder is mounted on the feeding rack. The device also includes a fixed frame, a rotating frame, a torsion spring, a limiting plate, a mesh frame, a conveying pipe, an airbag, an extrusion block, a rotating assembly, and a fixed assembly. The fixed frame is connected to the lifting rod of the cylinder. Rotating frames are rotatably connected to both sides of the fixed frame. Torsion springs are connected between the rotating frames and the fixed frame. Several extrusion blocks are connected to the rotating frames. Limiting plates are rotatably connected to the opposite side of each rotating frame. Mesh frames for placing automotive brake spring pads are rotatably connected to each rotating frame. An airbag equal in number to the extrusion blocks is mounted on the upper part of the reservoir. A liquid pump is mounted on the reservoir. A conveying pipe is connected between the airbags and the liquid pump. The upward movement of the extrusion blocks extrudes the airbags. A rotating assembly is provided on the reservoir, and a fixed assembly is provided on the rotating frame.

[0006] Furthermore, the rotating assembly includes a full gear and a rack. Both sides of the rotating frame are rotatably connected to the full gear that drives the mesh frame to rotate. Both sides of the mesh frame pass through the rotating frame and are connected to the full gear. Both sides of the liquid storage tank are connected to two racks. When the full gear moves upward, it meshes with the adjacent rack.

[0007] Furthermore, the fixing component includes a return spring and a sliding block. Two grooves are opened on both sides of the grid frame, and two sliding blocks that limit the grid frame are slidably connected on both sides of the rotating frame. The sliding blocks are located in adjacent grooves, and a return spring is connected between the sliding blocks and the rotating frame.

[0008] Furthermore, it also includes a support frame and blowers. The support frame is connected to the unloading rack, and several blowers are installed on the support frame.

[0009] Furthermore, it also includes limit frames and fixing blocks. Limit frames are connected to both sides of the unloading frame, and two pairs of fixing blocks for the extrusion rotating frame are connected to the unloading frame.

[0010] Furthermore, it also includes vibrators, with vibrators installed on both sides of the mounting bracket.

[0011] Furthermore, the unloading rack is arranged in a Z-shape, which allows for better unloading of the coated automotive brake spring pads.

[0012] Furthermore, the airbag has several spray holes, which allows the coating liquid to be evenly sprayed onto the car brake spring pads within the grid frame.

[0013] Furthermore, the airbags are all tilted on the reservoir, which allows the coating liquid to be sprayed more evenly and comprehensively onto the car brake spring pads within the grid frame through the spray holes.

[0014] Furthermore, the sliders are all rounded on the side closest to the adjacent grid frame.

[0015] The beneficial effects of this invention are as follows: 1. This invention uses the rotation of the gears to rotate the impregnated car brake spring pads 180 degrees, and then uses the upward movement of the extrusion block to extrude the air bladder, so that the coating liquid in the air bladder is sprayed from the spray hole to the bottom of the car brake spring pads for secondary coating, thereby making the car brake spring pads completely coated, thus improving the quality of the car brake spring pads, and at the same time avoiding the rework of the car brake spring pads, thereby improving the production efficiency of car brake spring pads.

[0016] 2. This invention controls a blower to quickly dry automotive brake spring pads, thereby preventing the brake spring pads from turning and wearing out, and also shortening the drying time of the automotive brake spring pads; then, by pressing the rotating frame with a fixed block, the rotating frame is rotated, thereby causing the automotive brake spring pads to automatically slide into the unloading rack, eliminating the need for manual collection, saving time and effort.

[0017] 3. This invention controls a vibrator to cause the impregnated automotive brake spring pads within the mesh frame to vibrate, thereby preventing the accumulation of coating fluid on the automotive brake spring pads and ensuring the coating quality of the automotive brake spring pads.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: A coating impregnation device for automotive brake spring pads, please refer to... Figures 1-14The system includes a storage tank 1, a feeding rack 2, a cylinder 3, a fixed frame 4, a rotating frame 5, a torsion spring 6, a limiting plate 7, a mesh frame 8, a conveying pipe 9, an airbag 10, an extrusion block 11, a rotating assembly, and a fixed assembly. The feeding rack 2 is fixedly connected to the upper part of the storage tank 1. The feeding rack 2 is arranged in a Z-shape to facilitate better feeding of the coated automotive brake spring pads. A cylinder 3 is bolted to the upper part of the feeding rack 2. A fixed frame 4 is fixedly connected to the lifting rod of the cylinder 3. Rotating frames 5 are rotatably connected to both sides of the fixed frame 4. Torsion springs 6 are fixedly connected between the rotating frame 5 and the fixed frame 4. Extrusion blocks 11 are fixedly connected to the four corners of the rotating frame 5. The rotating frames 5 are far apart from each other. Each side is rotatably connected to a limiting plate 7, and each rotating frame 5 is rotatably connected to a grid frame 8. Four airbags 10 are installed on the upper part of the liquid storage tank 1. Each airbag 10 has several spray holes 101, and the airbags 10 are all tilted on the liquid storage tank 1, so that the coating liquid can be sprayed more evenly and comprehensively onto the car brake spring pads in the grid frame 8 through the spray holes 101, thereby ensuring that the car brake spring pads are fully coated. A liquid pump is installed at the lower part of the liquid storage tank 1, and a delivery pipe 9 is fixedly connected between the airbags 10 and the liquid pump. When the squeezing block 11 moves upward, it will squeeze the airbags 10. A rotating component is provided on the liquid storage tank 1, and a fixing component is provided on the rotating frame 5.

[0041] Please see Figures 8-10 The rotating assembly includes a full gear 121 and a rack 122. The full gear 121 is rotatably connected to both the front and rear of the rotating frame 5. The mesh frame 8 passes through the rotating frame 5 and is connected to the full gear 121. Two racks 122 are fixed to the front and rear of the inner wall of the liquid storage tank 1. When the full gear 121 moves upward, it will mesh with the adjacent rack 122.

[0042] Please see Figure 10 and Figure 11 The fixing component includes a return spring 131 and a sliding block 132. The grid frame 8 has two grooves 130 on both the front and back. The upper part of the rotating frame 5 is slidably connected to two sliding blocks 132 on both the front and back. The side of the sliding block 132 closest to the adjacent grid frame 8 is arc-shaped. The rotation of the grid frame 8 can better compress the sliding block 132. The sliding blocks 132 are all located in the adjacent grooves 130. The return spring 131 is fixed between the sliding block 132 and the rotating frame 5.

[0043] First, control cylinder 3 to move its lifting rod upwards. This upward movement of the lifting rod drives the fixed frame 4 upwards, which in turn drives the rotating frame 5 and the mesh frame 8 upwards together. The upward movement of the rotating frame 5 drives the full gear 121 upwards, causing it to roll on the rack 122, thus rotating the full gear 121. This rotation of the full gear 121 drives the mesh frame 8 to rotate, which in turn compresses the sliding block 132. Since the sliding block 132 is rounded on the side closest to the adjacent mesh frame 8, it moves closer to the rotating frame 5, compressing the return spring 131. As the mesh frame 8 continues to rotate, it separates from the sliding block 132, and the mesh frame 8 no longer compresses the sliding block. The moving block 132 and the return spring 131 return to their original positions, causing the sliding block 132 to move away from the rotating frame 5 and back to its original position. After the grid frame 8 rotates 180 degrees, it will press the sliding block 132 again. Similarly, the sliding block 132 moves closer to the rotating frame 5, and the return spring 131 is compressed. When the sliding block 132 meets the adjacent groove 130, the return spring 131 returns to its original positions, causing the sliding block 132 to move away from the rotating frame 5 and back to its original position. The sliding block 132 will then be inserted into the adjacent groove 130, thereby fixing the grid frame 8. The grid frame 8 moves upward and separates from the reservoir 1. Then, the automotive brake spring pads that need to be coated and impregnated are placed in the grid frame 8. After the automotive brake spring pads are placed, the air is controlled... Cylinder 3 causes its lifting rod to move downwards, which in turn moves the fixed frame 4, rotating frame 5, limiting plate 7, and mesh frame 8 downwards together. The limiting plate 7, moving downwards, is squeezed by the inner wall of the reservoir 1, causing it to rotate 90 degrees and then stop rotating. The limiting plate 7 thus limits the rotating frame 5, preventing it from rotating under the weight of the brake spring pads. This allows the brake spring pads in the mesh frame 8 to reach the bottom of the reservoir 1 relatively stationary for coating impregnation. After coating impregnation, cylinder 3 is controlled again, causing its lifting rod to move the rotating frame 5, gear 121, mesh frame 8, and brake spring pads upwards together. The upward movement of gear 121 interacts with rack 122. Similarly, the grid frame 8 is flipped so that the lower part of the brake spring pad inside the grid frame 8 faces upward. The pump is controlled to deliver the coating liquid from the delivery pipe 9 to the airbag 10. As the rotating frame 5 moves upward, it also drives the squeezing block 11 to move upward. The upward movement of the squeezing block 11 squeezes the airbag 10, causing it to compress. This allows the coating liquid in the airbag 10 to be sprayed from the spray hole 101 onto the brake spring pad inside the grid frame 8, thus supplementing the coating on the lower part of the brake spring pad inside the grid frame 8 that was previously covered by the grid. Since the airbags 10 are all tilted on the reservoir 1, the coating liquid can be applied to all parts of the brake spring pad through the spray hole 101, resulting in uniform coating of the brake spring pad.This improves the quality of automotive brake springs and avoids rework, thereby increasing production efficiency. When the rotating frame 5 moves upwards and separates from the reservoir 1, the limiting plate 7 is manually rotated until it is flush with the rotating frame 5, allowing the impregnated automotive brake springs to be removed from the mesh frame 8.

[0044] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 12 It also includes a support frame 141 and a blower 142. The support frame 141 is fixedly connected to the unloading frame 2, and four blowers 142 are installed on the support frame 141.

[0045] When the brake spring pads in the grid frame 8 are soaked and move upwards, the blower 142 is controlled to blow air onto the brake spring pads in the grid frame 8, thereby drying the brake spring pads. This ensures that the upper part of the brake spring pads is fully dried before flipping, thus preventing flipping from reducing the quality of the brake spring pads. At the same time, after the bottom of the brake spring pads is re-sprayed, the bottom of the brake spring pads can also be dried, allowing the brake spring pads to dry quickly and thus improving the production efficiency of the brake spring pads.

[0046] Please see Figure 1 and Figure 13 It also includes a limit frame 151 and a fixing block 152. The left and right sides of the unloading frame 2 are fixed with limit frames 151. Two pairs of fixing blocks 152 are fixed on the unloading frame 2. When the rotating frame 5 moves upward, it will be squeezed by a pair of fixing blocks 152.

[0047] As the car brake spring pads in the grid frame 8 are immersed and move upward, the fixing block 152 will squeeze the rotating frame 5, causing the rotating frame 5 to rotate downward. The torsion spring 6 is compressed. Since the unloading rack 2 is arranged in a Z-shape, the car brake spring pads that have been immersed in the coating move to both sides of the unloading rack 2, so that the car brake spring pads in the grid frame 8 can automatically slide into the unloading rack 2. And since the limiting frame 151 limits the car brake spring pads, the car brake spring pads are piled on the unloading rack 2 for collection, so that no manual collection is required, reducing the amount of manual labor and saving time and effort.

[0048] Please see Figure 14It also includes a vibrator 161, with vibrators 161 installed at both the front and rear of the mounting bracket 4. When the car brake spring pads in the mesh frame 8 are soaked and move upwards, the vibrator 161 is controlled to drive the mounting bracket 4 to vibrate, thereby causing the rotating frame 5 and the mesh frame 8 to vibrate together. This can shake off the residual coating liquid on the car brake spring pads, thus preventing the coating liquid from accumulating on the car brake spring pads and ensuring the coating quality of the car brake spring pads.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
