Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts manufacturing, specifically an automated production line for brake pad hot pressing. Background Technology

[0002] Currently, brake pad production relies on a combination of manual labor and semi-automated equipment, resulting in low overall production efficiency. Furthermore, the manufacturing process primarily involves pressing friction powder and a steel backing under high temperature and pressure. Workers producing brake pads under these conditions inevitably operate in a hot and dusty environment, significantly threatening their physical and mental health.

[0003] In addition, brake pad production requires multiple processes, including weighing, feeding, pre-pressing, cleaning the mold, spraying release agent, placing the steel backing, pressing, demolding, and finishing. Without fully automated production of brake pads, real-time human intervention is required, which affects the efficiency, cost, and reliability of the entire production process.

[0004] Therefore, improving the full automation of brake pad production lines and reducing the labor intensity of workers has become an urgent technical problem to be solved. Summary of the Invention

[0005] This utility model addresses the above-mentioned technical problems by providing an automated production line for brake pad hot presses. Through modular collaborative design, it enables unmanned production of multiple hot presses throughout the entire process, supports the parallel production of multiple brake pad models, eliminates dust hazards in the production process, solves the problem of brake pad density consistency, improves product quality, and significantly increases production capacity while reducing product costs.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An automated production line for brake pad hot pressing machines includes two sets of hot pressing host units arranged opposite to each other, and each set of hot pressing host units is provided with several hot pressing hosts arranged in parallel.

[0008] A robot with a raw material gripper is installed at the middle position between the two sets of hot press main units;

[0009] Each set of hot press main units is equipped with a feeding machine and a feeding machine at one end, and a finished product unloading platform at the other end. A main truss is provided on the upper part. The main truss is equipped with a finished product gripper and a cleaning mechanism that can move horizontally and vertically between the hot press main units. A steel back feeding platform is provided between the two finished product unloading platforms.

[0010] The feeder automatically weighs the friction material and outputs it to the feeder; after receiving the friction material, the feeder performs vibration and flattening processes before providing it to the robot for gripping.

[0011] The robot uses its raw material gripper to pick up the steel back from the steel back feeding platform and place it onto the mold of the hot press host. Then, the raw material gripper throws the friction material provided by the feeder into the mold cavity of the hot press host. The hot press host presses the steel back and friction material into a brake pad.

[0012] The finished product gripper moves the pressed brake pads to the finished product unloading platform, the finished product unloading platform sorts and buffers the brake pads, and the cleaning mechanism cleans the mold from which the brake pads have been removed.

[0013] The automated production line for brake pad hot presses uses two sets of hot press main units. Each hot press main unit is supplied with raw materials by a robot, which automatically provides the steel backing and friction material. The finished product is then output through the finished product gripper on the main truss. Finally, the pressed brake pads are sorted and buffered on the finished product unloading platform. The cleaning mechanism on the main truss cleans the mold and continues the next round of product pressing.

[0014] This automated production line achieves fully unmanned production of multiple hot presses through modular collaborative design of robots and main trusses, supporting the parallel production of multiple models of brake pads; the cleaning mechanism eliminates dust hazards in the production process, making the working environment environmentally friendly and pollution-free; multiple hot presses continuously press products, significantly increasing production capacity, improving work efficiency, reducing product costs, and alleviating the labor intensity of workers.

[0015] A further optimized solution includes a hydraulic station platform that supplies oil to the hot press host, located between the two feeders. This placement of the hydraulic station platform between the two feeders results in a compact production line structure and efficient use of space.

[0016] In a further optimized design, the feeding machine is equipped with two automatic feeding hoppers, which respectively hold the outer and inner materials of the friction material;

[0017] The two hopper mechanisms weigh the fabric and base material according to product requirements and output them to the first discharge hopper group and the second discharge hopper group.

[0018] The hopper mechanism weighs the corresponding weight of fabric and base material according to the steel backing model in the mold on the hot press host. The feeding machine weighs the fabric and base material separately through dual hoppers, and accurately feeds them to the feeding machine through the first and second discharge hopper groups.

[0019] The further optimized solution includes a small truss mechanism, a receiving and vibrating mechanism, a turntable mechanism, several material transfer devices and several pre-pressing heads. The receiving and vibrating mechanism and the turntable mechanism are arranged side by side, and the small truss mechanism is located above the two and extends along the side by side.

[0020] The material transfer device corresponds one-to-one with the pre-pressing head; the material transfer device is provided with multiple conforming material boxes for loading friction material, and the pre-pressing head is provided with conforming pressure plates corresponding to the conforming material boxes, and the conforming pressure plates flatten the friction material in the conforming material boxes;

[0021] The material receiving and leveling mechanism is equipped with a material transfer device to receive friction material from the first and second discharge hopper groups and to level the friction material inside.

[0022] The turntable mechanism is divided into several stations, each where the transfer device and the pre-pressing head are placed, with the pre-pressing head located below the transfer device;

[0023] The small truss mechanism is equipped with a material transfer gripper and a pre-pressing head gripper; the material transfer gripper moves the material transferper back and forth between the turntable mechanism and the receiving and vibrating mechanism; the pre-pressing head gripper moves the pre-pressing head on the turntable mechanism to the conformal material box on the receiving and vibrating mechanism, and flattens the friction material inside, and then returns it to the turntable mechanism.

[0024] The material box of the transfer device and the pressure plate of the pre-pressing head are matched with the mold cavity respectively. The fabric and the base material are vibrated and pre-pressed to form a flat and layered material.

[0025] In a further optimized design, the hydraulic station platform includes two hydraulic stations mounted on a frame. Each of the two hydraulic stations corresponds to its respective hot press host unit, and the hydraulic stations supply oil to the hot press host unit via servo motor control.

[0026] The two hydraulic stations are mounted on an overhead frame. The space beneath the hydraulic station platform can be used for equipment maintenance and turntable changing, making full use of the floor space. Oil supply to the hot press is controlled by a servo motor, resulting in energy savings, environmental friendliness, and low noise.

[0027] In a further optimized design, the main truss is equipped with two movable Z-axis mechanisms, which can move between the hot press hosts and can be raised and lowered.

[0028] The finished product gripper and cleaning mechanism are respectively installed on the two moving Z-axis mechanisms.

[0029] Two moving Z-axis mechanisms drive the finished product gripper and cleaning mechanism to switch and move between various hot press hosts, realizing their corresponding functions.

[0030] The cleaning mechanism is further optimized to include a cleaning component, a moving component, a negative pressure dust removal component, and a spraying component.

[0031] The cleaning assembly includes a sealed dust collection hood, a dust collection pipe, a motor, and at least one cleaning brush. The dust collection pipe is connected to the inside of the sealed dust collection hood, the motor is located outside the sealed dust collection hood, and the cleaning brush is located inside the sealed dust collection hood. The motor drives the cleaning brush to rotate.

[0032] The moving component is provided with a guide rail slider and a driving component. The cleaning component is connected to the slider of the guide rail slider. The driving component drives the cleaning component to translate along the guide rail of the guide rail slider on the mold surface.

[0033] The negative pressure dust removal component is fixedly installed around the mold. It is equipped with a dust collection seat and a dust collection switch. When working, the dust collection pipe automatically seals and connects to the dust collection seat and triggers the dust collection switch.

[0034] The spraying assembly includes an automatic spray head disposed on the side of the cleaning assembly, the automatic spray head spraying a release agent into the mold cavity.

[0035] This cleaning mechanism simultaneously performs vacuuming, sweeping, and spraying operations through sweeping components, negative pressure dust removal components, and spraying components, shortening the process cycle time; and expands the cleaning coverage area of ​​the mold through moving components. The motor-driven sweeping brush cleans reactant residues and friction materials on the mold in a relatively sealed negative pressure environment, achieving simultaneous sweeping and dust removal and avoiding dust generation. Automatic nozzles spray release agent into the mold cavity, ensuring that the brake pads can be smoothly and easily removed from the mold without damage after pressing.

[0036] In a further optimized design, the cleaning mechanism also includes an auxiliary cleaning component. The auxiliary cleaning component is equipped with a brush to sweep the uncollected waste into a waste collection device on the side of the mold. The brush is located on the outside of the sealed dust collection cover.

[0037] After the cleaning component removes the main friction powder and reactants, some waste materials that are too large to be removed are swept by the brush of the auxiliary cleaning component into the waste collection device on the side of the mold.

[0038] The solution is further optimized so that the finished product gripper includes a rotary cylinder and several steel back suction positions. The spacing between the several steel back suction positions is consistent with the spacing between the mold cavities and is connected to the rotary cylinder, which drives the gripper to rotate.

[0039] The finished product gripper places the pressed brake pads onto the finished product unloading platform.

[0040] In a further optimized version, the finished product unloading platform includes a linear module, a receiving mechanism, and several parallel conveyor belts. The linear module drives the receiving mechanism to move between the receiving position and the corresponding conveyor belt buffer position.

[0041] The receiving mechanism is provided with a first receiving position, a second receiving position, and a material transfer pusher. The first receiving position and the second receiving position are arranged side by side, with the first receiving position being closer to the conveyor belt. When there is no product at the first receiving position, the material transfer pusher pushes the product from the second receiving position to the first receiving position.

[0042] The first receiving position is equipped with a flipping mechanism and a pushing mechanism. The flipping mechanism drives the first receiving position to rotate 90° to place the product vertically, and the pushing mechanism pushes the vertically placed product to the belt buffer.

[0043] Each conveyor belt on the finished product unloading platform is responsible for buffering brake pads produced by one hot press host. The linear module drives the receiving mechanism to receive the finished brake pads from the finished product gripper and sort them into the corresponding conveyor belts according to their model.

[0044] The brake pads at the first receiving position are flipped 90° by the flipping mechanism and then pushed onto the conveyor belt by the pushing mechanism. After the brake pads are flipped 90°, they are placed vertically to save buffer space.

[0045] The design has been further optimized, and the steel back feeding platform is equipped with a steel back gripping mechanism, a steel back positioning mechanism, and two turntables.

[0046] Each of the turntables is equipped with several steel backing bins and a lifting mechanism. The steel backing bins contain steel backings of the corresponding model. The turntable rotates to select the required steel backing bin, and the lifting mechanism lifts the selected steel backing bin to facilitate the gripping of the steel backing.

[0047] The steel back positioning mechanism has several steel back placement positions, and the spacing between them matches the spacing of the robot's raw material gripper.

[0048] The steel back gripping mechanism grabs the steel back in the steel back hopper and moves it to the steel back placement position. After several steel back placement positions are filled and the steel back positioning mechanism performs secondary positioning, the raw material gripper waits for the raw material to be grabbed into the mold of the hot press host.

[0049] The scheme is further optimized so that each hot press host includes several molds and hot press main cylinders; the molds correspond one-to-one with the hot press main cylinders, the brake pads are pressed in the molds, and the several hot press main cylinders are interconnected during the pressing process;

[0050] Each of the hot press main units is equipped with a synchronous motor and a mold changing guide rail. The synchronous motor controls several hot press main cylinders to exhaust gas synchronously, and the mold changing guide rail allows for mold replacement without stopping the entire production line.

[0051] During the brake pad pressing process, each hot press master cylinder is connected together. When connected, the pressing force on each mold product is the same. This ensures that when the weight of the material added to the four molds is slightly different, the compression amount of the product corresponding to each mold in each master cylinder is also different, thus ensuring that the density of each mold product is consistent.

[0052] The mold-changing guide rail allows for mold replacement without stopping the entire production line, enabling rapid mold changeover production.

[0053] The scheme is further optimized so that each of the hot press hosts includes four molds, and each group of hot press hosts includes four hot press hosts;

[0054] The robot's raw material gripper has four gripping positions, and the spacing between the four gripping positions is the same as the spacing between the four molds.

[0055] This automated production line for brake pad hot pressing can simultaneously produce up to eight different models of brake pads, greatly improving the flexibility of production scheduling and production efficiency.

[0056] This utility model has the following technical advantages compared with the prior art:

[0057] 1. This automated production line for brake pad hot presses uses a single robot to feed friction material and steel backing to all hot presses, resulting in high production efficiency and reliability.

[0058] 2. The mold cleaning adopts negative pressure dust collection, which improves the environmental quality of the production line and reduces the impact of dust on workers' health;

[0059] 3. The hydraulic station's oil supply is driven by a servo motor, which is low in noise and energy-saving;

[0060] 4. The hot press host adopts a mold changing guide rail for quick mold replacement, enabling rapid mold change production without stopping the production line;

[0061] 5. All hot press main units are equipped with corresponding steel backing feeding, friction material feeding and finished product unloading mechanisms, which can meet the production line's requirement to produce up to eight different models of brake pads simultaneously, greatly improving the flexibility of production scheduling and production efficiency.

[0062] 6. Friction material is pre-prepared in the material box by the feeder, and the base material and the surface material are processed in layers, which greatly reduces the auxiliary machine operation time of the hot press host and improves the performance and quality of the product.

[0063] 7. The entire production line is fully automated, requiring no manual intervention and saving labor costs.

[0064] 8. Each main unit has four hot press cylinders that independently press the mold products. During pressing, the oil inlets of the hot press cylinders can be connected to form a proportional pressing, ensuring consistent product density and improving product quality.

[0095] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0096] like Figures 1 to 19 As shown, this invention relates to a specific embodiment of an automated production line for brake pad hot pressing.

[0097] like Figure 1 , Figure 2 and Figure 4 As shown, the automated production line for brake pad hot press in this embodiment includes two sets of hot press host groups 10 arranged opposite to each other, and each set of hot press host groups 10 is provided with four parallel hot press hosts 100.

[0098] A robot 200 is installed in the middle position between the two sets of hot press main units 10. The robot 200 has a raw material gripper 210.

[0099] Each hot press host unit 10 is equipped with a feeding machine 300 and a feeding machine 400 at one end, and a finished product unloading platform 500 at the other end. A main truss 600 is provided on the upper part. A finished product gripper 700 and a cleaning mechanism 800 are provided on the main truss 600, which can move horizontally and rise and fall between the hot press host units 100. A steel back feeding platform 900 is provided between the two finished product unloading platforms 500.

[0100] The feeder 300 automatically weighs the friction material and outputs it to the feeder 400; after receiving the friction material, the feeder 400 vibrates and flattens it before providing it to the robot 200 for gripping.

[0101] The robot 200 uses its raw material gripper 210 to pick up the steel back from the steel back feeding platform 900 and place it onto the mold 110 of the hot press host 100. Then, the raw material gripper 210 throws the friction material provided by the feeder 400 into the cavity of the mold 110 of the hot press host 100. The hot press host 100 presses the steel back and friction material into a brake pad.

[0102] The finished product gripper 700 moves the pressed brake pads to the finished product unloading platform 500, where the brake pads are sorted and buffered. The cleaning mechanism 800 cleans the mold 110 from which the brake pads have been removed.

[0103] The two finished product unloading platforms 500 are equipped with main electrical boxes B00 on their sides. The main electrical boxes B00 contain a control system to control the automated operation of each piece of equipment on the production line.

[0104] The two sets of hot pressing main units 10 of the brake pad hot pressing automated production line are supplied with raw materials by robots 200, which automatically provide steel backing and friction materials; the finished products are output by the finished product gripper 700 on the main truss 600, and the brake pads are finally sorted and buffered on the finished product unloading platform 500; the cleaning mechanism 800 on the main truss 600 cleans the mold 110 and continues to the next round of product pressing.

[0105] This automated production line achieves fully unmanned production of multiple hot presses through modular collaborative design of robots 200 and main trusses 600, supporting the parallel production of multiple models of brake pads; the cleaning mechanism 800 eliminates dust hazards in the production process, making the working environment environmentally friendly and pollution-free; multiple hot presses 100 continuously press products, significantly increasing production capacity, improving work efficiency, reducing product costs, and alleviating the labor intensity of workers.

[0106] like Figure 1 and Figure 3 As shown, the automated production line for brake pad hot press also includes a hydraulic station platform A00, which supplies oil to the hot press host 100. The hydraulic station platform A00 is located between the two feeders 300. The location of the hydraulic station platform A00 between the two feeders 300 makes the entire production line structure compact and makes reasonable use of the floor space.

[0107] like Figure 5 As shown, the feeder 300 is equipped with two automatic feeding bins 310, which respectively hold the outer material and the inner material of the friction material;

[0108] The two hopper mechanisms 310 weigh the fabric and base material according to product requirements and output them to the first discharge hopper group 320 and the second discharge hopper group 330.

[0109] The material hopper mechanism 310 weighs the corresponding weight of fabric and base material according to the steel back model in the upper mold 111 of the hot press host 100. The feeding machine 300 weighs the fabric and base material separately through the dual material hoppers, and accurately feeds them to the feeding machine 400 through the first discharge hopper group 320 and the second discharge hopper group 330.

[0110] like Figure 6As shown, the feeder 400 includes a small truss mechanism 410, a receiving and vibrating mechanism 420, a turntable mechanism 430, four material transfer devices 440 and four pre-pressing heads 450. The receiving and vibrating mechanism 420 and the turntable mechanism 430 are arranged side by side, and the small truss mechanism 410 is located above the two and extends along the side by side.

[0111] The transfer device 440 corresponds one-to-one with the pre-pressing head 450; the transfer device 440 is provided with four contoured material boxes 441 for loading friction material, and the pre-pressing head 450 is provided with contoured pressure plates corresponding to the contoured material boxes 441, which flatten the friction material in the contoured material boxes 441.

[0112] A transfer device 440 is placed on the receiving and leveling mechanism 420 to receive friction material from the first discharge hopper group 320 and the second discharge hopper group 330, and level the friction material inside.

[0113] The turntable mechanism 430 is divided into four stations, each containing a transfer device 440 and a pre-pressing head 450. The pre-pressing head 450 is located below the transfer device 440.

[0114] The small truss mechanism 410 is equipped with a material transfer gripper 411 and a pre-pressing head gripper 412. The material transfer gripper 411 moves the material transferer 440 back and forth between the turntable mechanism 430 and the receiving and vibrating mechanism 420. The pre-pressing head gripper 412 moves the pre-pressing head 450 on the turntable mechanism 430 to the conformal material box 441 on the receiving and vibrating mechanism 420, and flattens the friction material inside, and then returns it to the turntable mechanism 430.

[0115] The conforming material box 441 of the transfer device 440 and the conforming pressure plate of the pre-pressing head 450 are respectively matched with the cavity of the mold 110, and the fabric and the base material are vibrated and pre-pressed to form a flat layered material.

[0116] like Figure 7 As shown, the hydraulic station platform A00 includes two hydraulic stations A20 mounted on the frame A10. The two hydraulic stations A20 correspond to their respective hot press host units 10. The hydraulic stations A20 supply oil to the hot press host units 100 through the control of the servo motor 813.

[0117] Two hydraulic stations A20 are mounted overhead via frame A10. The space below the hydraulic station platform A00 can be used as a maintenance area and a changeover passage for the turntable 930, making full use of the floor space. Oil supply to the hot press host 100 is controlled by a servo motor 813, which is energy-saving, environmentally friendly, and produces low noise.

[0118] like Figure 8 As shown, the main truss 600 is equipped with two movable Z-axis mechanisms 610, which can move between the hot press host 100 and can be raised and lowered.

[0119] The finished gripper 700 and the cleaning mechanism 800 are respectively installed on two moving Z-axis mechanisms 610.

[0120] Two movable Z-axis mechanisms 610 respectively drive the finished product gripper 700 and the cleaning mechanism 800 to switch and move between each hot press host 100, so as to realize their corresponding functions.

[0121] like Figure 10 and Figure 11 As shown, the cleaning mechanism 800 includes a cleaning component 810, a moving component 820, a negative pressure dust removal component 830, and a spraying component 840;

[0122] The cleaning assembly 810 includes a sealed dust suction cover 811, a dust suction pipe 812, a motor 813, and two cleaning brushes 814. The dust suction pipe 812 is connected to the inside of the sealed dust suction cover 811, the motor 813 is located outside the sealed dust suction cover 811, and the cleaning brushes 814 are located inside the sealed dust suction cover 811. The motor 813 drives the two cleaning brushes 814 to rotate through a synchronous belt and synchronous pulley mechanism.

[0123] The moving component 820 is provided with a guide rail slider 821 and a driving component 822. The cleaning component 810 is connected to the slider of the guide rail slider 821. The driving component 822 drives the cleaning component 810 to translate along the guide rail 912 of the guide rail slider 821 on the surface of the mold 110.

[0124] The negative pressure dust removal component 830 is fixedly installed around the mold 110. It is equipped with a dust collection seat 831 and a dust collection switch 832. When working, the dust collection pipe 812 automatically seals and connects to the dust collection seat 831 and triggers the dust collection switch 832.

[0125] The spraying assembly 840 includes an automatic spray head 841 disposed on the side of the cleaning assembly 810, which sprays a release agent into the cavity of the mold 110.

[0126] The cleaning mechanism 800 simultaneously performs vacuuming, cleaning, and spraying operations through the cleaning component 810, negative pressure dust removal component 830, and spraying component 840, shortening the cycle time. The moving component 820 expands the cleaning coverage area of ​​the mold 110. The motor 813 drives the cleaning brush 814 to clean reactant residues and friction materials on the mold 110 in a relatively sealed negative pressure environment, achieving simultaneous cleaning and dust removal to avoid dust generation. The automatic spray head 841 sprays a release agent onto the cavity of the mold 110, ensuring that the brake pads can be easily and undamagedly removed from the mold 110 after pressing.

[0127] like Figure 10 and Figure 11As shown, the cleaning mechanism 800 also includes an auxiliary cleaning component 850. The auxiliary cleaning component 850 is equipped with a brush 851 to sweep the uncollected waste into the waste collection device on the side of the mold 110. The brush 851 is located on the outside of the sealed dust collection cover 811.

[0128] After the cleaning component 810 sucks away the main friction powder and reactants, some waste materials that are too large to be sucked away are swept into the waste collection device on the side of the mold 110 by the brush 851 of the auxiliary cleaning component 850.

[0129] like Figure 9 As shown, the finished product gripper 700 includes a rotary cylinder 710 and four steel back suction positions 720. The spacing between the four steel back suction positions 720 is consistent with the cavity spacing of the mold 110, and they are connected to the rotary cylinder 710 and rotated by the rotary cylinder 710. Each steel back suction position 720 consists of six electromagnets, and each electromagnet is equipped with a buffer spring to accommodate steel backs with different protrusion positions. The finished product gripper 700 places the pressed brake pads onto the finished product unloading platform 500.

[0130] like Figure 12 and Figure 13 As shown, the finished product unloading platform 500 includes a linear module 510, a receiving mechanism 520, and four parallel conveyor belts 530. The linear module 510 drives the receiving mechanism 520 to move between the receiving position and the corresponding buffer position of the conveyor belt 530.

[0131] The receiving mechanism 520 is provided with a first receiving position 521, a second receiving position 522 and a material transfer push rod 523. The first receiving position 521 and the second receiving position 522 are arranged side by side, with the first receiving position 521 being closer to the belt conveyor 530. When there is no product at the first receiving position 521, the material transfer push rod 523 pushes the product from the second receiving position 522 to the first receiving position 521.

[0132] The first receiving position 521 is equipped with a flipping mechanism 524 and a pushing mechanism 525. The flipping mechanism 524 drives the first receiving position 521 to rotate 90° to place the product vertically, and the pushing mechanism 525 pushes the vertically placed product to the belt line 530 for buffering.

[0133] The flipping mechanism 524 includes a flipping cylinder 524a and two flipping bearings 524b. The two ends of the first receiving position 521 are respectively connected to the flipping bearings 524b. The flipping cylinder 524a drives the first receiving position 521 to rotate 90° around the flipping bearings 524b.

[0134] The pushing mechanism 525 includes a pushing cylinder 525a and a support plate 525b. The support plate 525b is located at the end of the first receiving position 521. It limits and supports the product during the product flipping process to prevent the product from falling. The pushing cylinder 525a pushes the vertically placed product to the belt conveyor 530.

[0135] The receiving mechanism 520 is also equipped with a rodless cylinder 526, which drives the material transfer push rod 523 to move back and forth.

[0136] Each belt conveyor 530 of the finished product unloading platform 500 is responsible for buffering brake pads produced by a hot press host 100. The linear module 510 drives the receiving mechanism 520 to receive the finished brake pads from the finished product gripper 700 and sort them onto the corresponding belt conveyor 530 according to their model for buffering.

[0137] The brake pads at the first receiving position 521 are flipped 90° by the flipping mechanism 524 and then pushed onto the belt line 530 by the pushing mechanism 525. After the brake pads are flipped 90°, they are placed vertically to save buffer space.

[0138] like Figure 1 and Figure 14 As shown, the steel back feeding platform 900 is equipped with a steel back gripping mechanism 910, a steel back positioning mechanism 920, and two turntables 930;

[0139] Each turntable 930 is equipped with several steel backing bins 931 and a lifting mechanism 932. The steel backing bins 931 contain steel backings of the corresponding model. The turntable 930 rotates to select the required steel backing bin 931, and the lifting mechanism 932 lifts the selected steel backing bin 931 to facilitate the gripping of the steel backing.

[0140] The steel back positioning mechanism 920 has four steel back placement positions 921, and the spacing between them matches the spacing of the raw material grippers 210 of the robot 200.

[0141] The steel back gripping mechanism 910 grips the steel back in the steel back hopper 931 and moves it to the steel back placement position 921. After the four steel back placement positions 921 are filled and the steel back positioning mechanism 920 performs secondary positioning, it waits for the raw material gripper 210 to grip it into the mold 110 of the hot press host 100.

[0142] like Figure 15 and Figure 16 As shown, the steel back gripping mechanism 910 includes a gripper fixing seat 911, a guide rail 912 is provided below the gripper fixing seat 911, a first slider 913 and a second slider 914 are provided on the guide rail 912, the first slider 913 is provided with a first suction position 915, and the second slider 914 is provided with a second suction position 916.

[0143] The gripper fixing base 911 is provided with a driving element 917 that connects to the first slider 913 and drives it to move back and forth along the guide rail 912;

[0144] The first slider 913 is provided with a middle push block 918 and a middle pull rod 919, and the second slider 914 is provided with a movable pull plate 91a; the middle pull rod 919 moves through the movable pull plate 91a, and the end of the middle pull rod 919 is limited by the movable pull plate 91a.

[0145] The gripper fixing seat 911 is provided with an intermediate limiting mechanism 91b in the middle to limit the movement of the second slider 914;

[0146] The first slider 913 moves in one direction and pushes the second slider 914 to a terminal position via the intermediate push block 918 to locate the minimum distance between the two; the first slider 913 moves in the opposite direction and pulls the second slider 914 to another terminal position via the moving pull plate 91a to locate the maximum distance between the two, and the intermediate limiting mechanism 91b positions the second slider 914.

[0147] like Figure 15 As shown, the drive element 917 is a rodless cylinder. Rodless cylinders are small in size and easy to install and use.

[0148] This steel back gripper mechanism can grab two steel backs from the steel back hopper 931 at a small distance within the steel back hopper 931 of the turntable 930, then increase the distance to the required distance and place them into the steel back positioning mechanism 920. The servo motor in the steel back positioning mechanism 920 drives the V-shaped clamp to limit the position and complete the secondary positioning. This achieves the purpose of grabbing various types of steel backs into the positioning mechanism according to the requirements with a simple structure and low cost.

[0149] The minimum distance between the first slider 913 and the second slider 914 of the steel back gripper mechanism is the distance between the two steel backs gripped from the steel back hopper 931. The maximum distance between the first slider 913 and the second slider 914 is the distance in the steel back positioning mechanism 920. The distance between the two steel backs in the positioning mechanism is matched by controlling the length of the intermediate pull rod 919 and adjusting the position of the intermediate limit mechanism 91b. The structure is simple, the cost is low, and the positioning accuracy is high.

[0150] like Figure 16 As shown, the steel-backed gripper mechanism also includes a lifting assembly 91c, which is connected to the gripper fixing seat 911. The lifting assembly 91c drives the gripper fixing seat 911 to move up and down. The lifting assembly 91c includes a cylinder, and the gripper fixing seat 911 is connected to the piston rod end of the cylinder. The up and down movement of the gripper fixing seat 911 is achieved by the cylinder, which has a simple structure and is convenient for installation and use.

[0151] like Figure 17As shown, the robot 200 has a raw material gripper 210. One end of the raw material gripper 210 grips four steel backs on the steel back positioning mechanism 920 of the steel back feeding platform 900 and puts them into the mold 110 of the hot press host 100. The other end of the raw material gripper 210 grips the transfer device 440 with friction material already loaded in the turntable mechanism 430 of the feeder 400 and puts the friction material therein into the cavity of the mold 110 of the hot press host 100.

[0152] like Figure 18 and Figure 19 As shown, each hot press host 100 includes four molds 110 and a hot press main cylinder 120; the molds 110 and the hot press main cylinders 120 correspond one-to-one, the brake pads are pressed in the molds 110, and the four hot press main cylinders 120 are interconnected during the pressing process.

[0153] The mold 110 is divided into an upper mold 111, a middle mold 112 and a mold core 123, each equipped with a heating module 150;

[0154] Each hot press host 100 is equipped with a synchronous motor 130 and a mold changing guide rail 140. The synchronous motor 130 controls the four hot press main cylinders 120 to exhaust air synchronously. The mold 110 can be changed without stopping the entire line by using the mold changing guide rail 140.

[0155] Each hot press 100 also includes a mold moving cylinder 160, a mold demolding cylinder 170, and two mold sealing cylinders 180.

[0156] During the brake pad pressing process, each hot press master cylinder 120 is connected together. When connected, the pressing force on each mold 110 product is the same. This ensures that when the weight of the material added to the four molds 110 is slightly different, the compression amount of the product corresponding to each master cylinder mold 110 is also different, thus ensuring that the density of each mold product is consistent.

[0157] The mold changing guide rail 140 allows for the replacement of mold 110 without stopping the entire production line, enabling rapid mold changeover production.

[0158] like Figure 17 and Figure 18 As shown, the raw material gripper 210 of the robot 200 has four gripping positions, and the spacing between the four gripping positions is the same as the spacing between the four molds 110.

[0159] This automated production line for brake pad hot pressing can simultaneously produce up to eight different models of brake pads, greatly improving the flexibility of production scheduling and production efficiency.

[0160] The working process of this automated production line for brake pad hot pressing is as follows:

[0161] When production begins, the hot press 100 first moves the middle mold 112 and the mold core 123 outside the hot press 100 and heats all molds 110 to the temperature required for production.

[0162] According to the brake pad model in the production schedule, the feeder 300 adjusts the corresponding friction material formula, weighs the fabric and the base material and puts them into the first discharge hopper group 320 and the second discharge group respectively;

[0163] Meanwhile, the small truss mechanism 410 on the feeder 400 lifts the transferor 440 onto the receiving and leveling mechanism 420 via the transferor gripper 411. The transferor 440 receives the friction material from the discharge hopper group of the feeder 300. The small truss mechanism 410 then lifts the pre-pressing head 450 via the pre-pressing head gripper 412. After the transferor 440 receives the fabric material from the friction material and levels it, the pre-pressing head 450 flattens the fabric material in the transferor 440. Then the transferor 440 receives the bottom material and levels it, and then the pre-pressing head 450 flattens it again. This ensures that the fabric and bottom material in the friction material are in a flat and layered state in the conformal material box 441.

[0164] Once the friction material has been received, the small truss mechanism 410 will place the transfer device 440 and the pre-compression head 450 back onto the turntable mechanism 430, waiting for the robot 200 to grab them.

[0165] Simultaneously operating is the steel back feeding platform 900. According to the production schedule, the steel back gripper mechanism picks up the steel back from the steel back hopper 931 on the turntable 930, first detects the color, and then places it into the steel back positioning mechanism 920. The steel back positioning mechanism 920 performs precise secondary positioning of the steel back so that the robot 200 can pick it up.

[0166] Once the steel back of the steel back feeding platform 900 is positioned and the transfer device 440 of the turntable mechanism 430 on the feeder 400 is ready with the friction material, the robot 200 uses the raw material gripper 210 to first pick up the steel back, then pick up the transfer device 440, and move it to the mold 110 of the hot press host 100 responsible for producing the corresponding model of brake pads.

[0167] If the mold 110 has a steel backing from the previous production run, it is picked up by the finished product gripper 700 and sorted and buffered by the finished product unloading platform 500. Then, the cleaning mechanism 800 cleans the mold 110 on the hot press host 100. After all this is done, the robot 200 can put the friction material in the transfer device 440 into the cavity of the mold 112 in the mold 110. After the material is put in, the transfer device 440 is put back onto the turntable mechanism 430 of the feeder 400.

[0168] While the robot 200 returns the transfer device 440, the cleaning mechanism 800 cleans up the friction material that may have been spilled on the upper surface of the middle mold 112 during the feeding process. Finally, the robot 200 places the steel back on the middle mold 112 and checks its position to ensure that the steel back is placed correctly.

[0169] At this point, robot 200 has completed its task and returned to its original position.

[0170] After ensuring that the friction material and steel backing are properly placed in mold 110, the mold-moving cylinder 160 of the hot press host 100 moves the middle mold 112 and mold core 123 into the hot press host 100, and the mold-sealing cylinder 180 then attaches them together with the upper mold 111. The hot press main cylinder 120 pushes the mold core 123 to pressurize and maintain pressure on both the friction material and the steel backing, and during this process, venting is performed according to the production process requirements of this brake pad.

[0171] After the pressure is maintained for the set time, the hot pressing main cylinder 120 and the demolding cylinder 170 retract, and the mold moving cylinder 160 pushes the middle mold 112, mold core 123 and the product out of the hot pressing main unit 100. After being pushed out to the position, the demolding cylinder 170 lifts the mold core 123, and removes the finished brake pad from the mold 110, and then waits for the next round of production.

[0172] This automated production line for brake pad hot presses achieves fully unmanned production across multiple hot presses through modular collaborative design, supports parallel production of multiple brake pad models, eliminates dust hazards in the production process, solves the problem of brake pad density consistency, improves product quality, and significantly increases production capacity while reducing product costs.

[0173] In summary, as described in the specification and figures, this utility model has been manufactured into actual samples and subjected to multiple use tests. The test results demonstrate that this utility model achieves its intended purpose, and its practicality is beyond doubt. The embodiments described above are merely for illustrative purposes and are not intended to limit the scope of this utility model.
