Description

Technical Field

[0001] The present application relates to the technical field of brake pad production, and specifically to a brake pad production line. Background Art

[0002] Brake pads, also known as brake leather, are one of the most important safety components in a car's braking system. Brake pads convert the vehicle's kinetic energy into heat energy by generating friction with the brake disc or drum, thereby slowing or stopping the vehicle and ensuring the safety of the vehicle and its passengers. Brake pads are generally composed of friction blocks and backing plates. The friction blocks are the part that directly contacts the brake disc or drum, generating friction, and are typically made of a variety of friction materials. The backing plate supports and secures the friction blocks and is typically made of metal. The brake pad production process includes a series of processes such as heat treatment, cutting, grinding, and drilling. Through precise processing, the brake pad is shaped into a structure and size that meets the installation requirements of the vehicle braking system. Specifically, heat treatment improves the material properties of the brake pad, cutting determines its basic contour, grinding ensures surface flatness, and drilling creates the conditions for subsequent installation and fixation. During laser cutting of brake pads, laser energy is highly concentrated on a small area, rapidly melting and vaporizing the material. A high-speed assist gas ejected from a nozzle is directed toward the cutting area, attempting to remove this melted and vaporized material, creating a neat cut seam. However, due to factors such as laser parameters, gas characteristics, cutting head position, and material properties, some of the melt can solidify rapidly after cutting and adhere to the edges of the cut, forming dross. This not only reduces the cut surface quality and affects workpiece precision, but also negatively impacts subsequent processing and performance. Therefore, it is necessary to provide a brake pad production line to address these issues.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0020] Example 1: Figures 1-10 As shown, the present application provides a brake pad production line, comprising an oven 1 for heat treating the brake pad, a laser cutting assembly 2, a drilling assembly 3, a scraping assembly 4, and a clamping assembly 5; The laser cutting assembly 2 includes a first workbench 21, which has a chamber 22. A first moving unit is installed on the first workbench 21, and the first moving unit is suitable for realizing movement in the Y-axis direction. The first moving unit includes a guide rail 214 fixedly installed on the first workbench 21 near both sides, and a first slider 215 is slidably installed on the guide rail 214, and the first slider 215 is suitable for sliding along the linear direction of the guide rail 214. A support seat 220 is installed on the first slider 215, and two groups of support plates 216 are fixedly installed on the first workbench 21 at one side of the guide rail 214 at the same time, and a first screw rod 217 is installed on a bearing between the two groups of support plates 216, and a sliding seat 218 is threadedly connected to the first screw rod 217, and the top of the sliding seat 218 is connected to the support seat 220, and a motor 219 is fixedly installed on the support plate 216, and the output end of the motor 219 is connected to one end of the first screw rod 217; When the motor 219 is started, its output shaft drives the first screw 217 to rotate on the bearings between the two sets of support plates 216. The screw's rotational motion is converted into linear motion of the sliding seat 218 along the screw's axis. At the same time, the guide rails 214 on both sides and the first slider 215 form a stable sliding guide structure. The first slider 215 can slide smoothly along the Y-axis on the guide rails 214, providing precise guidance for the movement of the support seat 220 and preventing it from deflecting or shaking during movement. The top of the sliding seat 218 is fixedly connected to the support seat 220, so that the linear motion of the sliding seat 218 can synchronously drive the support seat 220 to translate along the Y-axis. like Figure 7-Figure 8As shown, a scraper assembly 4 is installed on the two sets of guide rails 214, and the scraper assembly 4 includes two sets of mounting seats 41 fixedly mounted on the side of one set of guide rails 214, and a second screw rod 42 is mounted on a bearing between the two sets of mounting seats 41, and a driving member 44 is fixedly mounted on the side of one set of mounting seats 41, and the output end of the driving member 44 is connected to the second screw rod 42, and a screw rod seat 43 is threadedly connected to the second screw rod 42. At the same time, two sets of assembly seats 45 are fixedly mounted on the side of the other set of guide rails 214, and a guide rod 46 is fixedly mounted between the two sets of assembly seats 45. A limiting block 47 is slidably mounted on the two sets of guide rods 46, and a scraper unit is connected between the screw rod seat 43 and the limiting block 47; The scraping unit includes a connecting rod 414 connected between the screw seat 43 and the limiting block 47, and a scraper 420 is movably mounted on the connecting rod 414. The scraper 420 is suitable for contacting the surface of the brake pad to scrape off the slag on the surface of the brake pad. A flushing unit is connected between the screw seat 43 and the limiting block 47, and the flushing unit includes a support rod 48 fixedly mounted on the screw seat 43 and the limiting block 47, one end of the support rod 48 is mounted with a gear 49 on a bearing, and a movable tube 410 is fixedly mounted on the mutually adjacent sides of the two sets of gears 49, and two sets of nozzles 411 are connected and mounted on the movable tube 410, and the nozzles 411 are tilted, and a fixed tube 412 is movably mounted between the two sets of movable tubes 410, and the fixed tube 412 extends into the two sets of movable tubes 410, and a torsion spring 413 is connected between the fixed tube 412 and one end of the two sets of movable tubes 410, and the torsion spring 413 makes the nozzles 411 on the movable tube 410 be in a vertical setting state in the initial state; A through-hole is provided at the position where the fixed tube 412 extends into the movable tube 410. The through-hole is adapted to connect to the connection between the nozzle 411 and the movable tube 410. Furthermore, a hose 424 is connected to the fixed tube 412. The hose 424 is adapted to connect to an external water supply device to supply water to the nozzle 411 through the through-hole to clean the slag attached to the surface of the scraper 420. It should be noted that the scraper assembly 4 is located on the guide rail 214 near the driving member 44. At the same time, a rack 423 is fixedly installed on the guide rail 214 away from the driving member 44. The rack 423 is suitable for driving the gear 49 to rotate. The number of teeth on the rack 423 allows the movable tube 410 to rotate only 30 degrees toward the scraper 420, so that the through hole is suitable for docking with the connection between the nozzle 411 and the movable tube 410. When the drive member 44 is powered on and started, its output shaft drives the second screw 42 to rotate around the bearing, and the circular motion of the second screw 42 is converted into linear movement of the screw seat 43 along the axial direction. During this process, the limiting block 47 slides synchronously on the guide rod 46. The fixed structure composed of the guide rod 46 and the assembly seat 45 provides a stable linear guide for the limiting block 47, ensuring that the screw seat 43 and the limiting block 47 maintain parallel movement. The two are rigidly connected by the connecting rod 414, driving the scraper 420 installed thereon to perform reciprocating linear motion along the guide rail 214. The scraper 420 maintains moderate contact with the surface of the brake pad, and uses the cutting edge to scrape off residual slag during movement to complete the initial cleaning operation.

[0021] While scraper 420 is scraping debris, the flushing unit simultaneously prepares for operation. A torsion spring 413 provides preload force, maintaining the nozzle 411 on movable tube 410 in a vertical position in its initial state. At this point, nozzle 411 is misaligned with the through-hole in fixed tube 412, preventing water from flowing through. As the scraping unit moves along guide rail 214 with screw holder 43 to a position near rack 423, gear 49 mounted on support rod 48 begins to engage with rack 423. Rack 423 is fixedly mounted at the end of guide rail 214, and its tooth profile precisely matches that of gear 49.

[0022] As the scraping unit continues to move, the meshing teeth of rack 423 drive gear 49, which in turn drives the coaxially mounted movable tube 410 to rotate synchronously. Due to the design of the number and length of teeth on rack 423, when gear 49 rotates to 30 degrees, the nozzle 411 on movable tube 410 rotates to a position tilted toward scraper 420. At this point, the connection between nozzle 411 and movable tube 410 perfectly aligns with the through-hole in fixed tube 412. The high-pressure water flow delivered by the external water supply equipment through the hose 424 passes through the internal channels of the fixed tube 412 and the movable tube 410, and is finally ejected from the nozzle 411 at an inclined angle to flush the slag particles remaining on the surface of the scraper 420, thereby realizing automatic cleaning of the scraper 420 and ensuring that it continues to maintain efficient scraping performance. After the flushing is completed, the scraping unit continues to move, the gear 49 disengages from the rack 423, and under the reset action of the torsion spring 413, the movable tube 410 and the nozzle 411 return to their initial vertical state, ready for the next cleaning cycle.

[0023] like Figure 2-Figure 3 and Figure 6 As shown, specifically, a leak hole 23 is opened on the first workbench 21, and the leak hole 23 is suitable for collecting the flushing water. A collecting hopper 24 is fixedly installed on the bottom surface of the first workbench 21, and the collecting hopper 24 extends into the chamber 22. The collecting hopper 24 is suitable for guiding the flushing water, and a valve is provided at one end opening of the collecting hopper 24, and the valve is suitable for discharging the flushing water collected by the collecting hopper 24; During the cleaning process after laser cutting, the water flow ejected from the nozzle 411 of the flushing unit carries slag particles and scatters on the surface of the first workbench 21 after cleaning the scraper 420. Since the leakage hole 23 opened on the first workbench 21 is aligned with the direction of water flow, the flushing water naturally falls through the leakage hole 23 under the action of gravity. The collecting hopper 24 fixedly installed on the bottom surface of the first workbench 21 has a funnel-shaped structure, which accurately receives the flushing water falling from the leakage hole 23, and uses its inclined inner wall to guide the water flow into the inside of the hopper body, and finally merges into the chamber 22 of the first workbench 21 for temporary storage. When the flushing water in the collecting hopper 24 reaches a certain amount or needs to be cleaned, the operator can open the valve at the opening of the collecting hopper 24, and the flushing water is discharged from the opening driven by gravity for subsequent wastewater treatment.

[0024] like Figure 2-Figure 5 As shown, specifically, a second mobile unit 221 is connected between the two groups of support seats 220. The second mobile unit 221 has a similar structure to the first mobile unit, and the second mobile unit 221 is suitable for achieving movement in the X-axis direction. By driving the screw to rotate, the circular motion is converted into the X-axis linear motion of the sliding seat 218, cooperating with the stable sliding of the slider along the guide rail 214, and the first slider 215 of the second mobile unit 221 is defined as the second slider here. A third moving unit 222 is mounted on the second slider. The third moving unit 222 has a similar structure to the first moving unit and is suitable for achieving movement in the Z-axis direction. The first slider 215 of the third moving unit 222 is defined as the third slider, and a laser cutting head 223 is fixedly mounted on the third slider. The third moving unit 222 drives the laser cutting head 223 on the third slider to rise and fall along the Z-axis. The three units work together to achieve precise positioning and movement of the laser cutting head 223 in three-dimensional space. Two sets of fixing units for clamping the brake pads are installed on the first workbench 21. The fixing units include a fixing platform 26 fixedly installed on the first workbench 21, and a first protrusion 27 is provided at one end of the fixing platform 26. A second protrusion 28 is provided at the other end of the first protrusion 27. A hinge seat 29 is movably connected to the second protrusion 28. The hinge seat 29 has a handle 210. The handle 210 is suitable for driving the hinge seat 29 to rotate along the hinge with the second protrusion 28. A connecting rod 211 is movably connected to the hinge seat 29, and one end of the connecting rod 211 is movably connected to a linkage rod 213. The linkage rod 213 movably passes through the first protrusion 27. The linkage rod 213 is suitable for horizontal movement left and right on the first protrusion 27, and a clamping plate 212 is fixedly installed on one end of the linkage rod 213. A mounting platform 25 is also fixedly mounted on the first workbench 21. This platform is suitable for placing brake pads. The laser cutting assembly 2 utilizes mechanical linkage and lever transmission to achieve stable clamping and precise positioning of the brake pads. During operation, the operator first places the brake pad flat on the mounting platform 25 of the first workbench 21 to complete the initial positioning. Then, by applying external force through the handle 210, the articulated seat 29 rotates about the hinge point of the second protrusion 28. This rotational motion is converted into traction on the connecting rod 213 through the movable connection between the articulated seat 29 and the connecting rod 211. Because the connecting rod 213 passes through the first protrusion 27 and is guided by it, it can only move horizontally left and right when pulled by the connecting rod 211. As the connecting rod 213 moves, the clamping plate 212 fixed to one end of it moves synchronously. The clamping plates 212 of the two fixed units move toward each other under the action of the lever, firmly clamping the brake pads placed on the placement platform 25. like Figure 1 and Figure 9-10 As shown, specifically, the drilling assembly 3 includes a second workbench 31, and a protective cover 32 is fixedly installed on the second workbench 31, and a base 35 is fixedly installed on the second workbench 31, and a sliding platform 36 is slidably installed on the base 35. At the same time, fixed seats 33 are fixedly installed on both sides of the second workbench 31 at the same time. A third screw rod is installed on a bearing between the two groups of fixed seats 33, and a motor 34 is fixedly installed on the side of one group of fixed seats 33, and the output end of the motor 34 is connected to the third screw rod; When motor 34 is started, its output shaft rotates the third screw, supported by the bearings of fixed base 33. The threaded pair between the third screw and sliding platform 36 converts the screw's circular motion into linear translation of sliding platform 36 along base 35. Base 35 provides guidance for sliding platform 36, ensuring its linear motion along a predetermined path and preventing lateral deviation. By controlling the direction, speed, and operating time of motor 34, the direction, speed, and displacement of sliding platform 36 can be adjusted. A drilling unit 38 is fixedly mounted on the top of the inner wall of the protective cover 32. The drilling unit 38 is a prior art and will not be described in detail here. The drilling unit 38 is suitable for drilling holes in the brake pads. When the motor 34 is started, its output shaft drives the third screw to rotate under the support of the bearing of the fixed seat 33. Through the threaded pair transmission between the screw and the sliding platform 36, the circular motion of the screw is converted into a linear translation of the sliding platform 36 along the base 35, which can realize the flexible adjustment of the moving direction, speed and displacement of the sliding platform 36, so as to accurately position the brake pad to be processed in the processing area of ​​the drilling unit 38.

[0025] A drilling unit 38, fixed to the top of the inner wall of the protective cover 32, serves as the actuator. Its high-speed rotating drill bit cooperates with the linear motion of the sliding platform 36 to drill holes in the positioned brake pads. The drilling unit 38's built-in pressure sensing and depth control system monitors the drilling process in real time, automatically adjusting the drill feed speed and depth according to preset parameters to ensure consistent drilling quality. The protective cover 32 provides safety protection and debris collection during the process, preventing flying metal chips from injuring the operator. The entire system achieves brake pad drilling through the seamless integration of mechanical transmission and electrical control.

[0026] like Figure 1 and Figure 7-Figure 8 As shown, specifically, a buffer unit is movably provided on the connecting rod 414, and the buffer unit includes two sets of movable sleeves 415 connected to the connecting rod 414 by bearings. The two sets of movable sleeves 415 are located on both sides of the scraper 420, and a support plate 416 is provided on the side close to each other of the two sets of movable sleeves 415. The scraper 420 is connected between the two sets of support plates 416, and an extension rod 421 is fixedly installed on the movable sleeve 415. At the same time, a protrusion 417 is fixedly installed on the side of the support plate 416, and a limiting rod 418 is obliquely fixedly installed on the protrusion 417. The limiting rod 418 passes through the extension rod 421, and a waist groove 422 for the displacement of the limiting rod 418 is opened on the extension rod 421, and a spring 419 is sleeved on the limiting rod 418. At the same time, a limiting portion is provided at one end of the limiting rod 418, one end of the spring 419 is connected to the limiting portion, and the other end of the spring 419 abuts against the side of the extension rod 421. It should be noted that there is a certain gap between the scraper 420 and the connecting rod 414, and the scraper 420 is adapted to be vertically arranged under the action of the spring 419 through the two sets of movable sleeves 415. When the scraper 420 contacts the slag on the brake pad, the scraper 420 is adapted to rotate a certain angle along the axis of the connecting rod 414 to avoid hard contact with the slag. The working principle of the buffer unit is based on the elastic buffer of spring 419 and the mechanical limit mechanism, which ensures that the scraper 420 has both flexible contact capabilities and can maintain a stable working posture when cleaning slag. In the initial state, the spring 419 is mounted on the limiting rod 418, with one end resting on the limiting part and the other end contacting the side of the extension rod 421. The elastic force maintains the movable sleeve 415 and the connected scraper 420 in a vertical state. When the scraper 420 contacts the slag on the surface of the brake pad, the force exerted by the slag on the scraper 420 causes the scraper 420 to be tilted, driving the movable sleeve 415 to rotate around the connecting rod 414; At this point, extension rod 421 slides along limiting rod 418 within waist groove 422, compressing spring 419. Spring 419, through its own elastic deformation, absorbs the impact force on scraper 420, preventing a hard collision between scraper 420 and the slag and reducing wear. The limiting structure formed by limiting rod 418 and waist groove 422 controls the rotation angle of scraper 420, ensuring that its posture is adjusted within a reasonable range. This ensures effective slag removal while preventing excessive rotation that could lead to cleaning failure. When the slag resistance disappears, spring 419 resumes its elastic deformation, pushing extension rod 421 back into position, returning scraper 420 to a vertical position and preparing for subsequent cleaning operations.

[0027] like Figure 1 and Figure 9-10 As shown, specifically, a fixed platform 37 is fixedly mounted on the sliding platform 36, and a clamping assembly 5 is mounted on the fixed platform 37. The clamping assembly 5 is used to clamp the brake pad, and the clamping assembly 5 includes two sets of mounting angle seats 51 fixedly mounted on the fixed platform 37. A cylinder 52 is fixedly mounted on the mounting angle seat 51. The telescopic end of the cylinder 52 passes through the mounting angle seat 51, and a clamping plate 53 is fixedly mounted on the telescopic end of the cylinder 52. The clamping plate 53 is suitable for moving closer to or farther away from each other as the telescopic end of the cylinder 52 moves, so as to clamp the brake pad. Two sets of slide rails 54 are fixedly mounted on the fixed platform 37, and slide blocks 55 are slidably mounted on the slide rails 54. A support platform 56 is connected between the two sets of slide rails 54, and the support platform 56 is suitable for placing a pair of brake pads. Before drilling, the operator places the brake pad flat on a support platform 56, which is supported by a sliding block 55 between two sets of slide rails 54 to ensure stability and fine-tuning of its position. Subsequently, the cylinder 52 on the mounting angle seat 51 is activated. The cylinder 52 uses compressed air as a power source to push its telescopic end to perform linear reciprocating motion. Because the clamping plate 53 is fixed to the telescopic end of the cylinder 52, and the telescopic end passes through the mounting angle seat 51, when the cylinder 52 extends, the two sets of clamping plates 53, guided by the mounting angle seat 51, move synchronously toward the brake pad on the support platform 56; when the cylinder 52 contracts, the clamping plates 53 move away from each other. By controlling the extension and contraction of the cylinder 52, adaptive clamping of brake pads of different sizes can be achieved, ensuring that they maintain a fixed posture during the drilling process and avoiding processing errors caused by shaking.

[0028] At the same time, the sliding structure formed by the slide rail 54 and the sliding block 55 provides flexible fine-tuning space for the support platform 56. The operator can manually adjust the position of the support platform 56 on the slide rail 54 according to actual needs to ensure that the relative positions of the brake pad and the drilling unit 38 are accurately matched.

[0029] To summarize: the brake pads first enter oven 1 for heat treatment. By controlling the temperature and time, the physical and chemical properties of the brake pad material are changed, improving its mechanical properties such as hardness and wear resistance, laying the foundation for subsequent processing.

[0030] The heat-treated brake pad is placed on the placement platform 25 of the first workbench 21. The operator holds the handle 210 to drive the hinge seat 29 to rotate around the second protrusion 28, and pulls the connecting rod 213 through the connecting rod 211 to move the two sets of clamps 212 toward each other to firmly clamp the brake pad.

[0031] The first, second, and third mobile units 221 and 222 work in tandem. The motor 219 rotates the first screw 217, which, through threaded motion, moves the slide 218 along the screw's axis, driving the support 220 to translate along the Y-axis. The second mobile unit 221 operates in a similar manner, achieving movement along the X-axis. The third mobile unit 222 drives the laser cutting head 223 up and down along the Z-axis. These three units work together to precisely position the laser cutting head 223 in three dimensions, allowing it to cut the brake pads.

[0032] The driver 44 rotates the second screw 42, causing the screw seat 43 to move axially. The limiting block 47 slides synchronously on the guide rod 46. Together, the two components drive the scraper 420 to reciprocate along the guide rail 214 via the connecting rod 414. The spring 419 and the limiting structure in the buffer unit ensure that the scraper 420 flexibly contacts the brake pad surface, removing any residual slag.

[0033] When scraper 420 reaches a specific position, rack 423 meshes with gear 49, driving movable tube 410 to rotate 30 degrees, allowing nozzle 411 to mate with the through-hole of fixed tube 412. An external water supply system supplies water through hose 424. High-pressure water flows through nozzle 411 and sprays it at an angle, flushing away slag from the surface of scraper 420. Once the flushing is complete, torsion spring 413 resets movable tube 410 and nozzle 411.

[0034] The flushing water carries the slag through the leak hole 23 of the first workbench 21 and falls into the collection bucket 24, flows into the chamber 22 for temporary storage, and is discharged through the valve for treatment.

[0035] The cleaned brake pad is placed on the support platform 56 of the fixed platform 37 in the drilling assembly 3. The platform is supported by the slide rail 54 and the slide block 55, which can be fine-tuned. The cylinder 52 is started, and its telescopic end drives the clamping plate 53 to move, clamping the brake pad.

[0036] Motor 34 rotates the third screw, which in turn translates the sliding platform 36 linearly along the base 35, precisely positioning the brake pad under the drilling unit 38. The drill bit of drilling unit 38 rotates at high speed, coordinating with the movement of sliding platform 36 to complete the drilling operation. A built-in system monitors and adjusts drilling parameters in real time to ensure quality, while protective cover 32 simultaneously protects and collects debris.

[0037] To address the problem of dross formation after laser cutting, the slag scraper assembly 4 effectively removes molten material adhering to the edge of the brake pad cut by combining a scraper unit and a flushing unit. The scraper blade 420 of the scraper unit flexibly contacts the molten material, preventing damage to the brake pad surface. Simultaneously, the flushing unit uses high-pressure water to promptly clean the scraper blade 420, preventing secondary contamination and improving the cut surface quality. It also reduces surface unevenness and precision deviations caused by dross, ensuring a clean cut edge.

[0038] The laser cutting assembly 2 and drilling assembly 3 utilize a screw drive mechanism, combined with precise control by an electrical control system, to achieve high-precision positioning and stable operation of the moving parts. During the cutting and drilling processes, positioning errors caused by slag can be effectively overcome, ensuring that the brake pad's dimensional accuracy and hole position precision meet requirements, thus preventing performance issues caused by insufficient precision.

[0039] At the same time, the buffer unit reduces the hard collision between the scraper 420 and the slag, and the flushing unit cleans the equipment residue in time, effectively reducing equipment wear, extending the service life of key components such as the laser cutting head 223, the scraper 420, and the drilling unit 38, reducing equipment maintenance costs and downtime, and ensuring the stable operation of the production line.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
