Description

Technical Field

[0001] This application relates to the technical field of brake disc manufacturing, and in particular to brake disc cleaning and coating lines. Background Technology

[0002] Brake discs, also known as brake pads, are an important component of the braking systems used in automobiles, motorcycles, and other vehicles. They are disc-shaped metal parts, typically made of cast iron, steel, or composite materials.

[0003] Cleaning, drying, and spraying are key processes in brake disc production. Currently, although there are various brake disc cleaning and spraying equipment, these devices are often scattered, resulting in a cumbersome and inefficient process. Therefore, it is necessary to integrate the multiple processes of cleaning, drying, and spraying into a single production line to improve processing efficiency.

[0004] During the cleaning and coating process, multiple brake discs are laid out on the production line. The brake discs are arranged in multiple rows along the conveyor direction, and each row of brake discs is spaced out with multiple discs perpendicular to the conveyor direction. When the conveyor is not in a consistent manner or when the brake discs are not placed at a certain distance, the numerous brake discs are prone to colliding together. This can result in some parts of the brake discs not being cleaned, dried, and coated, thus reducing the cleaning and coating effect of the brakes. Moreover, the collision between the brake discs can also easily cause damage to the brake discs, all of which lead to a decrease in the quality of the brake discs. Summary of the Invention

[0005] To improve the quality of brake discs, this application provides a brake disc cleaning and spraying line.

[0006] The brake disc cleaning and coating line provided in this application adopts the following technical solution: A brake disc cleaning and coating line includes a frame, a conveyor line, a cleaning device, a drying device, and a coating device. The frame is also equipped with an arrangement device to neatly arrange the brake discs. Multiple arrangement devices are arranged in front of the cleaning device and between the drying device and the coating device. The arrangement device includes: A rotating shaft is rotatably mounted on the frame, and its axis is perpendicular to the conveying direction of the conveyor line. Multiple push rings are spaced apart on the rotating shaft along the axis of rotation and are used to push adjacent brake discs in the same row away from each other and to maintain a certain space between two adjacent brake discs. The push plate is mounted on the frame and slides up and down to push two adjacent batches of brake discs away from each other and to maintain a certain space between two adjacent rows of brake discs. The drive mechanism is used to drive the rotating shaft to rotate and simultaneously drive the push plate to move.

[0007] By adopting the above technical solution, multiple brake discs are placed on a conveyor line for transport. The drive mechanism drives the rotating shaft to rotate, which in turn drives multiple push rings to rotate. The push rings are used to push the multiple brake discs in the same row away from each other, so that a certain space is maintained between adjacent brake discs. At the same time, the drive mechanism drives the push plate to move vertically. When the two rows of brake discs move so that the push plate is between the two rows of brake discs, the push plate moves down and inserts between the two rows of brake discs. The brake discs in front of the push plate move forward normally, while the push plate blocks the movement of the next batch of brake discs. Then the push plate moves up, thus maintaining a certain space between multiple brake discs. This space facilitates subsequent cleaning and drying. After drying, the brake discs are arranged by the arranging device to facilitate subsequent spraying. Therefore, the cleaning, drying and spraying effect of the brake discs is greatly improved, and the probability of brake discs colliding with each other is reduced, thus improving the quality of the brake discs.

[0008] Optionally, the drive mechanism includes: Drive components are used to drive the rotating shaft to rotate; The drive disc is rotatably mounted on the frame and connected to the rotating shaft via a linkage assembly. The drive shaft is eccentrically mounted on the drive disc. The spring is connected at both ends to the drive shaft and the push plate, respectively.

[0009] By adopting the above technical solution, the driving component drives the rotating shaft to rotate, the rotating shaft drives the driving disc to rotate through the linkage component, the driving disc rotates and drives the driving shaft to rotate around the axis of the driving disc, the driving shaft rotates and the spring causes the push plate to move up and down. When the push plate moves down and is not between the two rows of brake discs, the push plate presses against the brake disc under the action of gravity. At this time, the spring tension can overcome part of the weight of the push plate, reducing the damage of the push plate to the brake disc, and also reducing the resistance generated when the brake disc moves. When the brake disc moves forward and the push plate is between the two rows of brake discs, the push plate moves down under the action of gravity, thereby blocking the movement of the next row of brake discs. Then the driving plate continues to move up under the spring tension, and the next batch of brake discs continues to move. In this way, a certain space is maintained between the two adjacent batches of brake discs while reducing the damage to the brake discs.

[0010] Optionally, the linkage component includes: The main gear is mounted on the rotating shaft; The secondary gear is mounted on the drive disc and meshes with the main gear.

[0011] By adopting the above technical solution, the rotation of the rotating shaft drives the main gear to rotate, and the rotation of the main gear drives the secondary gear and the drive disk to rotate.

[0012] Optionally, the lower surface of the push plate is provided with a guide angle to facilitate insertion between two adjacent rows of brake discs.

[0013] By adopting the above technical solution, when the guide angle is inserted between the two rows of brake discs, the guide angle pushes the front row of brake discs forward and the rear row of brake discs backward until the push plate extends between the two rows of brake discs, thereby enabling a certain space to be maintained between adjacent batches of brake discs more quickly.

[0014] Optionally, the push ring is slidably sleeved on the rotating shaft and threadedly connected to a positioning screw that presses against the rotating shaft for positioning.

[0015] By adopting the above technical solution, the push ring can be replaced, and it can also adapt to the arrangement of brake discs of different sizes and numbers, thus improving the adaptability of the structure.

[0016] Optionally, multiple cleaning devices are spaced apart, and a scrubbing mechanism is provided on the frame and located between the multiple cleaning devices. The scrubbing mechanism includes: Two movable blocks are slidably mounted on the frame along the axis of rotation and located on the upper and lower sides of the brake disc; Two brushing rollers are rotatably mounted on the frame with their axes parallel to the axis of rotation. The two brushing rollers are located on the upper and lower sides of the brake disc and work together to brush the brake disc. A pusher assembly, mounted on a rack, is used to push two moving blocks closer together or further apart. A rotating assembly, mounted on the frame, is used to drive the two scrubbing rollers to rotate.

[0017] By adopting the above technical solution, impurities are prone to adhering to the brake disc. It is difficult to remove the impurities by spraying alone, which reduces the spraying effect. Extending the time can improve the spraying effect, but it reduces the spraying efficiency, making it impossible to achieve both. The rotating component drives two brush rollers to rotate, while simultaneously pushing the component to move two moving blocks closer or further apart. This allows the two brush rollers to rotate and move closer or further apart simultaneously, brushing the upper and lower surfaces of the brake disc during their movement. Furthermore, the cleaning device first cleans the brake disc, then it is brushed by the brush rollers, and finally sprayed clean. This significantly reduces the probability of impurities adhering to the brake disc, improving the cleaning effect. The closer or further apart the brush rollers cause the brushing forces on the upper and lower brake discs to cancel each other out, reducing the probability of the brush rollers colliding with or interfering with subsequent drying, thus further improving the quality of the brake disc.

[0018] Optionally, the pushing component includes: A fixed block is set on the frame and has a rotating groove. An annular moving groove is set on the rotating groove. When the brushing roller is rotated on the rotating groove, a moving column is slidably set on the moving groove. The rotation of the brushing roller drives the moving column to move in the moving groove and drives the brushing roller and the moving column to move back and forth. The swing arm is rotatably mounted on the frame and extends to two moving blocks at both ends, with waist-shaped swing holes. Two swing columns are respectively set on two moving blocks and slidably mounted on two swing holes.

[0019] By adopting the above technical solution, the rotation of the scrubbing roller drives the rotation of the moving column, and the moving column moves in the moving groove, thereby driving the scrubbing roller and the moving block to move. At the same time, the movement of one moving block drives the other moving block to move in the opposite direction through the swing rod, so that the two scrubbing rollers rotate and move closer or further away from each other.

[0020] Optionally, the rotating assembly includes: Two rotating gears are respectively mounted on two washing rollers and mesh with each other; A rotating component is mounted on the frame and is slidably connected to one of the scrubbing rollers via a sliding assembly, thereby driving the scrubbing roller to rotate.

[0021] By adopting the above technical solution, the driving component drives one brush roller to rotate through the sliding assembly, and the rotation of the brush roller drives another brush roller to rotate through two rotating gears, thereby realizing the rotation of the two brush rollers to brush the brake disc; at the same time, the sliding assembly facilitates the movement of the brush rollers, so that the driving component does not need to move but the brush rollers can be moved.

[0022] Optionally, the sliding component includes: A sliding sleeve is used to connect with rotating parts and is slidably fitted onto the scrubbing roller; A sliding block is set on a sliding sleeve and slidably mounted on a scrubbing roller, so that the sliding sleeve and the scrubbing roller rotate simultaneously.

[0023] By adopting the above technical solution, the driving component drives the sliding sleeve to rotate, the rotation of the sliding sleeve drives the sliding block and the brushing roller to rotate, and the movement of the brushing roller drives the sliding block to move on the sliding sleeve, thereby enabling the driving component to drive the brushing roller to rotate without moving.

[0024] Optionally, a filter frame for filtration is placed on the frame and below the two washing rollers.

[0025] By adopting the above technical solution, the filter frame is used to filter impurities, thereby improving the cleaning effect on the brake disc.

[0026] In summary, this application includes at least one of the following beneficial technical effects: Multiple push rings are used to push multiple brake discs in the same row away from each other, so that a certain space is maintained between adjacent brake discs. At the same time, the drive mechanism drives the push plate to move vertically. When the two rows of brake discs move so that the push plate is between the two rows of brake discs, the push plate moves down and inserts between the two rows of brake discs, so that a certain space is maintained between multiple brake discs. This space is for subsequent cleaning and drying. Then, the dried brake discs are arranged by the arranging device to facilitate subsequent spraying. Therefore, the cleaning, drying and spraying effect of brake discs is greatly improved, and the probability of brake discs colliding with each other is reduced, thus improving the quality of brake discs.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a brake disc cleaning and spraying line.

[0031] Reference Figure 1The brake disc cleaning and coating line includes a frame, a conveyor line 11, a cleaning device 2, a drying device 13, and a coating device 14. The conveyor line 11 is used to transport brake discs. The cleaning device 2, the drying device 13, and the coating device 14 are arranged at intervals along the conveyor line 11 and are used to clean, dry, and coat the brake discs, respectively. Two coating devices 14 are also arranged at intervals. The brake discs transported by the conveyor line 11 are cleaned and baked in sequence, then divided into two batches, and finally coated by the two coating devices 14. Arrangement devices 3 are installed on the frame, in front of the cleaning device 2 and between the drying device 13 and the coating device 14. The arrangement devices 3 are used to arrange multiple brake discs neatly and maintain a certain space between adjacent brake discs, thereby facilitating the cleaning, drying, and coating of the brake discs.

[0032] Reference Figure 1 and Figure 2 The cleaning device 2 includes a cleaning tank 21, a cleaning pump, and spray pipes 22. The cleaning tank 21 is located below the conveyor line 11 and contains cleaning fluid. The cleaning pump is fixedly installed inside the cleaning tank 21. Two sets of spray pipes 22 are arranged at intervals along the conveyor line 11, and each set of spray pipes 22 has multiple spray pipes arranged at intervals along the conveyor line 11. All spray pipes 22 are connected to the spray pump. Spray pipes 22 are also arranged on both the upper and lower sides of the conveyor line 11, and the spray pipes 22 spray and clean both the upper and lower surfaces of the brake disc simultaneously. The drying device 13 adopts an existing hot air drying system, and the spraying device 14 also adopts an existing spraying system, which will not be described in detail here.

[0033] The following explanation uses the arrangement device 3 located in front of the cleaning device 2 as an example. The conveyor line 11 is formed by the cooperation of multiple rotating conveyor rollers 12. The conveyor rollers 12 are horizontal and their axes are perpendicular to the conveying direction of the conveyor line 11. The arrangement device 3 includes a rotating shaft 31, multiple push rings 32, a push plate 33 and a drive mechanism 4. The rotating shaft 31 is rotatably mounted on the frame and located above the conveyor line 11. The axes of the rotating shaft 31 and the conveyor rollers 12 are parallel, that is, the axis of the rotating shaft 31 is perpendicular to the conveying direction of the conveyor line 11.

[0034] Reference Figure 2 and Figure 3 The push ring 32 is coaxially slidably sleeved on the rotating shaft 31, and a positioning screw is threaded onto the push ring 32 to abut against the rotating shaft 31 and position the push ring 32. The push ring 32 is located between two adjacent brake discs. The rotation of the rotating shaft 31 drives multiple push rings 32 to rotate, and the multiple push rings 32 push multiple brake discs in the same row away from each other, so that a certain space is formed between two adjacent brake discs.

[0035] The push plate 33 is vertically slidably mounted on the frame, and the push plate 33 is located on the side of the rotating shaft 31 near the brake disc input. At the same time, the push plate 33 is located above the conveyor line 11, and the length direction of the push plate 33 is parallel to the axis of the conveyor roller 12. The drive mechanism 4 is used to drive the rotating shaft 31 to rotate and the push plate 33 to move vertically. The drive mechanism 4 includes a drive component 41, a drive disc 42, a drive shaft 43 and a spring 44. The drive component 41 is a servo motor. The drive component 41 is fixedly mounted on the frame and its output shaft is connected to the rotating shaft 31 to drive the rotating shaft 31 to rotate.

[0036] The drive disk 42 is rotatably mounted on the frame and located above the push plate 33. There are two drive disks 42 located at both ends of the push plate 33. The rotation axis of the drive disk 42 is parallel to the axis of the conveying roller 12. There are two drive shafts 43 eccentrically mounted on the side walls of the two drive disks 42. The axis of the drive shaft 43 is parallel to the rotation axis of the drive disk 42. There are two springs 44, which correspond one-to-one with the two drive shafts 43. A fixing ring 45 is fixedly mounted on the upper surface of both ends of the push plate 33. The two ends of the springs 44 are hooked onto the drive shafts 43 and the fixing rings 45.

[0037] The drive disk 42 is connected to the rotating shaft 31 via a linkage assembly 5. The linkage assembly 5 includes a main gear 51 and a secondary gear 52. The main gear 51 is keyed to the rotating shaft 31, and the secondary gear 52 is keyed to the drive disk 42 and meshes with the main gear 51. The drive component 41 drives the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the drive disk 42 to rotate via the main gear 51 and the secondary gear 52. The rotation of the drive disk 42 drives the drive shaft 43 to rotate around the axis of the drive disk 42. The rotation of the drive shaft 43 pulls the push plate 33 up and down via the spring 44.

[0038] The push plate 33 moves according to a set time, which is determined by the speed of the brake disc movement. When the two rows of brake discs move and the push plate 33 moves between the two rows of brake discs, the push plate 33 moves down and extends between the two rows of brake discs, thereby maintaining a certain space between the two rows of brake discs. Then the push plate 33 moves up above the brake discs. Therefore, the push plate 33 and the push ring 32 cooperate to maintain a certain space between adjacent brake discs. A guide angle 34 is provided on the lower surface of the push plate 33 to facilitate insertion between the two rows of brake discs.

[0039] Reference Figure 2 and Figure 4A brushing mechanism 6 is installed on the frame and between the two sets of spray pipes 22 to brush the upper and lower surfaces of the brake disc. The brushing mechanism 6 includes two moving blocks 61, two brushing rollers 62, a pushing component 63 and a rotating component 7. The two moving blocks 61 are slidably mounted on the frame along the axis of the conveying roller 12 and are located on the upper and lower sides of the brake disc. The two moving blocks 61 slide in opposite directions. One end of each of the two brushing rollers 62 is rotatably mounted on the two moving blocks 61, and the axes of the two brushing rollers 62 are parallel to the axis of the conveying roller 12 and cooperate to brush the upper and lower surfaces of the brake disc.

[0040] The pushing component 63 is mounted on the frame and is used to push the two moving blocks 61 closer to each other or further apart. The pushing component 63 includes a fixed block 64, a swing rod 65 and two swing columns 66. The fixed block 64 is fixedly mounted on the frame and has a rotating groove 67 that coincides with the axis of the brushing roller 62. The brushing roller 62, located above the brake disc, is rotatably mounted on the rotating groove 67. A ring-shaped and inclined moving groove 68 is coaxially provided on the rotating groove 67. A moving column 69 is fixedly mounted on the brushing roller 62 and slidably mounted on the moving groove 68. The rotation of the brushing roller 62 drives the moving column 69 to move on the moving groove 68. The rotation of the brushing roller 62 and the cooperation of the moving groove 68 and the moving column 69 realize the reciprocating movement of the brushing roller 62.

[0041] The swing rod 65 is rotatably mounted on the frame and extends to the two moving blocks 61 at both ends. Swing holes 651 are opened along the length of the swing rod 65. Two swing columns 66 are fixedly mounted on the two moving blocks 61 and are slidably mounted on the two swing holes 651 respectively. The brush roller 62 connected to the fixed block 64 reciprocates and drives another brush roller 62 to reciprocate and move back and forth through the swing rod 65. The two brush rollers 62 rotate and reciprocate and move back and forth at the same time, so that the two move in opposite directions.

[0042] The rotating assembly 7 is mounted on the frame and is used to drive the two washing rollers 62 to rotate. The rotating assembly 7 includes two rotating gears 71 and a rotating component 72. The two rotating gears 71 are respectively keyed to one end of the two washing rollers 62 near the fixed block 64 and mesh with each other. The rotating component 72 is a rotating motor. The rotating component 72 is fixedly mounted on the frame, and the output shaft of the rotating component 72 coincides with the axis of the washing roller 62 located below the brake disc. At the same time, the output shaft of the rotating component 72 is slidably connected to the washing roller 62 through the sliding assembly 8 and is used to drive the washing roller 62 to rotate. A filter frame for filtration is fixedly mounted on the frame and located below the two washing rollers 62.

[0043] The sliding assembly 8 includes a sliding sleeve 81 and a sliding block 82. The sliding sleeve 81 is coaxially fixedly mounted on the output shaft of the rotating component 72, and the brushing roller 62 is rotatably sleeved inside the sliding sleeve 81, with the brushing roller 62 slidably connected to the sliding sleeve 81. The sliding block 82 is fixedly mounted on the sliding sleeve 81 and slidably mounted on the brushing roller 62, so that the rotating component 72 drives the sliding sleeve 81 to rotate, and the sliding sleeve 81 drives the sliding block 82 and the brushing roller 62 to rotate. At the same time, the rotation of the brushing roller 62 drives the other brushing roller 62 to rotate through two rotating gears 71, and when the brushing roller 62 moves, the sliding block 82 cooperates with the sliding sleeve 81 to avoid positioning.

[0044] The working principle of this application embodiment is as follows: The conveyor line 11 moves the brake discs. The drive unit 41 drives the rotating shaft 31 and multiple push rings 32 to rotate. The multiple push rings 32 push two adjacent brake discs away from each other. The rotating shaft 31 drives the push plate 33 to move up and down. When the push plate 33 is between two rows of brake discs, the push plate 33 moves down between the two rows of brake discs, so that a certain space is formed between the two rows of brake discs. Then the push plate 33 moves up above the brake discs. Therefore, the push plate 33 and the push rings 32 work together to form a certain space between two adjacent brake discs, so that multiple brake discs are arranged neatly, which facilitates subsequent cleaning, drying and spraying.

[0045] The spray pipe 22 sprays and washes the upper and lower surfaces of multiple neatly arranged brake discs. Then the brake discs are moved to the brush rollers 62. The rotating part 72 drives the two brush rollers 62 to rotate and move back and forth. The two brush rollers 62 work together to brush and wash the brake discs. Then the brake discs continue to be moved to the spray pipe 22 for spraying. Then the brake discs are dried and coated in sequence through the drying device 13 and the spraying device 14, thereby improving the quality of the brake discs.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
