Description

Technical Field

[0001] This utility model relates to the field of hot pressing production equipment technology, and in particular to an automated brake pad production equipment. Background Technology

[0002] Brake pads are an important component of the automotive braking system, playing a crucial role in the vehicle's braking performance. Brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and friction blocks. The heat insulation layer is made of a non-heat-conducting material and is used for heat insulation. The friction blocks are composed of friction materials and adhesives, and are pressed against the brake disc and brake drum during braking to generate friction, thereby achieving the purpose of decelerating and braking the vehicle.

[0003] Brake pads typically require multiple processes during production, including material preparation, feeding, pressing, and unloading. This process is quite complex and requires various equipment for each step. The pressing process generally employs a hot pressing technique, where the mold on the press is heated. During pressing, the powder in the mold is melted and extruded into shape. However, when changing product models, the mold needs to be replaced and reheated, which takes time and delays production, leading to slower production speed and reduced efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] like Figure 1 and Figure 2As shown, an automated brake pad production equipment includes a batching mechanism 58, a hot press 1, a preheating mechanism, a mold conveyor 2, a conveyor frame 3, and a steel backing feeding mechanism. The batching mechanism 58 is a powder weighing and dispensing device, capable of mixing, weighing, and dispensing friction materials. The powder weighing and dispensing device is existing technology and uses commercially available equipment, so it will not be described in detail. Multiple hot presses 1 are arranged in a straight line, capable of simultaneously pressing brake pads of different specifications and models. The four sides of each hot press 1 are the front, rear, left, and right sides. Each hot press 1 is equipped with a replaceable hot press mold. Friction materials, adhesives, and steel backings are placed in the mold cavity of the hot press mold for pressing. The batching mechanism 58 is located on the left side of the hot press 1. The preheating mechanism is located on the right side of the hot press 1 and can preheat the hot press mold. Preheating raises the temperature of the hot press mold, allowing it to be directly replaced on the hot press 1. After replacement, the brake pads can be pressed. The mold conveyor 2, located behind the hot press 1, transports the preheated hot press mold to the corresponding hot press 1 for replacement. The conveyor frame 3, fixedly positioned at the front of the hot press 1, includes multiple vertically arranged uprights and horizontal crossbars at the top of the uprights. A feeding device, a stirring device, and a picking device are horizontally slidably mounted on the crossbars of the conveyor frame 3, used for feeding friction materials, stirring, and picking up brake pads, respectively. The steel backing feeding mechanism is located at the front of the hot press 1, with the conveyor frame 3 positioned between the steel backing feeding mechanism and the hot press 1. The steel backing feeding mechanism stores the steel backing and places it on the hot press mold of the hot press 1.

[0043] In this invention, friction material is placed in the feeding mechanism 58 for feeding and unloading. The unloading device slides along the conveyor frame 3 to the feeding mechanism 58, and the feeding mechanism 58 can quantitatively transport the prepared powder to the unloading device. The unloading device slides along the conveyor frame 3 to the front of the hot press 1, and the unloading device transports the powder to the mold cavity of the hot press mold. Then, the stirring device slides on the conveyor frame 3 and moves to the mold cavity of the hot press mold to stir and flatten the powder in the mold cavity. Subsequently, the steel back feeding mechanism can grab the stored steel back and place it in the mold cavity of the hot press mold. The hot press 1 presses the brake pad to form a shape. The formed brake pad can be grabbed by the picking device that is slidably set on the conveyor frame 3.

[0044] It should be noted that the hot press mold is provided with oil channels for heating. The oil channels of the hot press mold placed on the hot press 1 are connected to the external hot oil pipeline. The hot oil in the hot oil pipeline can circulate through the oil channels, so that the hot press mold always maintains a high temperature, which is convenient for pressing the brake pads.

[0045] In another embodiment, such as Figure 3As shown, the preheating mechanism includes a fixed frame 4 fixedly mounted on the right side of the hot press 1. A preheating box 5 is fixedly mounted on the upper end of the fixed frame 4. A preheating cavity with a front-to-back through-hole is opened on the preheating box 5. A heating tube is inserted into the preheating box 5 to raise the temperature inside the preheating cavity. Sealing plates 6 are hinged to the front and rear sides of the preheating box 5 to seal the openings at both ends of the preheating cavity. A push rod 7 is horizontally slidably mounted on the fixed frame 4. The push rod 7 is located on the front side of the preheating box 5. The mold conveyor 2 is located on the rear side of the preheating box 5. An installation frame 8 is fixedly mounted on the mold conveyor 2. A pull rod 9 is horizontally slidably mounted on the installation frame 8. A mold take-up plate 10 is fixedly mounted on the end of the pull rod 9 near the preheating box 5. The mold take-up plate 10 is located between the preheating box 5 and the installation frame 8. A mold electromagnet 11 is fixedly mounted on the mold take-up plate 10. In this embodiment, the hot press mold to be heated is placed on the fixed frame 4 on the front side of the preheating box 5. The push rod 7 and the preheating box 5 are located on the front and rear sides of the hot press mold, respectively. The sealing plate 6 located on the front side of the preheating box 5 is opened, and the push rod 7 slides towards the side closer to the preheating box 5, which can push the hot press mold into the preheating cavity of the preheating box 5. Then the sealing plate 6 closes the preheating cavity, and the preheating box 5 can heat the hot press mold. After heating to a certain temperature, the sealing plate 6 located on the rear side of the preheating box 5 is opened, and the pull rod 9 drives the mold picking plate 10 to move towards the side closer to the preheating box 5 until the mold electromagnet 11 contacts the hot press mold and picks it up. The pull rod 9 moves backward to pull the hot press mold out of the preheating box 5 to the mold conveyor 2. Finally, the mold conveyor 2 conveys the hot press mold to the hot press machine 1 where the hot press mold needs to be replaced for replacement. The replaced hot press mold has a certain temperature and can be pressed without reheating, reducing waiting time, speeding up the pressing speed, and improving production efficiency.

[0046] Furthermore, the preheating box 5 is equipped with opening and closing cylinders on the left and right sides. The cylinder barrel of the opening and closing cylinder is hinged to the side wall of the preheating box 5, and the piston rod of the opening and closing cylinder is hinged to the sealing plate 6. The upper end of the sealing plate 6 is hinged to the preheating box 5. Therefore, the sealing plate 6 can be opened or closed by extending and retracting the piston rod of the opening and closing cylinder.

[0047] Furthermore, a push-in cylinder is fixedly installed at the bottom of the fixed frame 4. The piston rod of the push-in cylinder is fixedly connected to the lower end of the push rod. The extension and retraction of the piston rod of the push-in cylinder can drive the push rod 7 to slide. A sliding groove is provided on the fixed frame 4, and the push rod 7 is slidably installed in the sliding groove so that the push rod 7 can slide normally. A discharge cylinder is fixedly installed on the mounting frame 8. The piston rod of the discharge cylinder is fixedly connected to the mold taking plate 10. The extension and retraction of the piston rod of the discharge cylinder can drive the mold taking plate 10 to slide, thereby pulling the hot pressing mold out of the preheating box 5.

[0048] Furthermore, a slide rail is fixedly installed at the lower part of the fixed frame 4, and a slider is fixedly installed at the bottom of the push rod 7. The slider is slidably mounted on the slide rail, which makes the push rod 7 more stable during the sliding process.

[0049] Furthermore, a top block is fixedly installed on the upper end of the push rod 7 near the preheating box 5. The top block abuts against the side of the hot pressing mold. When the push rod 7 pushes the hot pressing mold into the preheating box 5, after the push rod 7 abuts against the side of the preheating box 5, the top block can continue to send the hot pressing mold into the preheating box 5 to a certain depth. After the sealing plate 6 closes the preheating box 5, a certain distance is left between the hot pressing mold and the sealing plate 6, which can better heat the hot pressing mold.

[0050] Furthermore, a fixing plate 12 is fixedly installed on the fixing frame 4. The fixing plate 12 is vertically arranged, and there are two fixing plates 12, which are located on both sides of the slide groove. The fixing plate 12 and the push rod 7 are located on the same side of the preheating box 5. Multiple rollers 13 are rotatably arranged on the upper end surface of the fixing plate 12. The highest point of the rollers 13 is higher than or equal to the bottom surface of the preheating chamber. The rollers 13 are in rolling contact with the hot pressing mold, so the hot pressing mold can be directly sent into the preheating box 5. In this embodiment, the hot pressing mold to be heated is placed on the rollers 13 of the fixing plate 12. When the hot pressing mold is sent into the preheating box 5, the sliding push rod 7 pushes the hot pressing mold to one side of the preheating box 5. The hot pressing mold is in rolling contact with the rollers 13, so the pushing force used to push the hot pressing mold can be reduced, and the bottom of the hot pressing mold can be avoided from being rubbed.

[0051] Furthermore, a limiting plate 62 is fixedly installed on the fixing frame 4. The limiting plate 62 is located on the front side of the preheating box 5. The limiting plate 62 is parallel to the fixing plate 12 and is located on one side of the fixing plate 12. The position of the limiting plate 62 corresponds to the position of the preheating cavity in the preheating box 5. After the hot pressing mold is placed on the roller 13 of the fixing plate 12, one side of the hot pressing mold abuts against the limiting plate 62. The limiting plate 62 can limit the position of the hot pressing mold so that the hot pressing mold will not collide with the preheating box 5 when it is pushed into the preheating box 5.

[0052] Furthermore, such as Figure 3 As shown, the mold conveyor 2 includes a frame located behind the preheating box 5 and the hot press 1. A chain is rotatably mounted on the frame along its length. The chain is driven to rotate by a sprocket mounted on the frame. A movable plate is fixedly mounted on the chain and can slide horizontally along the frame. When the movable plate slides to the rear of the preheating box 5, the mold taking plate 10 takes the hot press mold out of the preheating box 5 and places it on the movable plate. Then, the movable plate slides on the frame to the rear of the hot press 1 where the mold needs to be replaced, and then pushes the heated hot press mold from the movable plate onto the hot press 1.

[0053] It should be noted that a feeding cylinder 63 is fixedly installed on the frame of the mold conveyor 2. The number of feeding cylinders 63 is the same as the number of hot presses 1. The position of the feeding cylinders 63 corresponds one-to-one with the position of the hot presses 1 and is located on the rear side of the hot presses 1. A pusher plate is fixedly installed on the piston rod of the feeding cylinder 63. When the moving plate drives the hot press mold to move to the rear side of the hot presses 1, the piston rod of the feeding cylinder 63 extends and can push the hot press mold into the hot presses 1 to complete the replacement of the hot press mold.

[0054] Furthermore, such as Figure 4 As shown, the hot press 1 includes a hydraulic press body 14, on which a support plate 15 is fixedly mounted. One end of the support plate 15 extends to the front side of the hydraulic press body 14. The support plate 15 extending to the front side of the hydraulic press body 14 is located below the feeding device. The hot press mold is slidably mounted on the support plate 15. In this embodiment, the hot press mold can slide on the support plate 15. When the hot press mold slides to the front of the hydraulic press body 14, the feeding device can add powder into the mold cavity of the hot press mold. At the same time, the stirring device can stir and flatten the powder. Then, the steel back feeding mechanism places the steel back into the mold cavity. Subsequently, the hot press mold slides on the support plate 15 to the inside of the hydraulic press body 14, and the hydraulic press body 14 presses and shapes it. After the brake pad is pressed and shaped, the hot press mold slides on the support plate 15 to the outside of the hydraulic press body 14. The material taking device takes out the pressed brake pad and places it in the storage box located on the right side of the preheating mechanism for centralized storage. The hydraulic press body 14 is a commercially available hydraulic press, which is a conventional technology and will not be described in detail here.

[0055] Furthermore, such as Figure 14 As shown, in another embodiment, a dust collection box 64 is fixedly installed on the hydraulic press body 14. The dust collection box 64 is located on the front side of the hydraulic press body 14 and on both sides of the support plate 15. The dust collection box 64 has a dust collection hole on the side near the support plate 15. The dust collection box 64 is connected to an external dust removal device. The dust removal device and the connection method between the dust removal device and the dust collection box 64 are in the prior art and will not be described in detail here. During the feeding process, the hot press mold slides along the support plate 15 to the front side of the hydraulic press body 14. During the process of adding powder to the hot press mold, in order to avoid dust scattering, the dust removal device is started, and the dust collection box 64 generates suction force, which can suck the scattered dust into the dust collection box 64 through the dust collection hole, and finally enter the dust removal device for processing.

[0056] Furthermore, such as Figure 5As shown, a first connecting plate 16 and a second connecting plate 17 are horizontally slidably arranged on the conveyor frame 3. A driving assembly is provided between the transmission frame 3 and the first connecting plate 16, as well as between the transmission frame 3 and the second connecting plate 17, for driving the first connecting plate 16 and the second connecting plate 17 to slide on the connecting frame 3. The first connecting plate 16 and the second connecting plate 17 are both horizontally slidably arranged on the crossbar at the upper part of the conveyor frame 3. The feeding device and the stirring device are arranged on the first connecting plate 16, and the picking device is arranged on the second connecting plate 17.

[0057] Specifically, the drive assembly includes a helical rack and a slide rail fixedly mounted on a crossbar on the upper part of the conveyor frame 3 along the length direction. The slide rail and the helical rack are arranged in parallel. A slider is fixedly mounted on both the first connecting plate 16 and the second connecting plate 17. The slider is slidably mounted on the slide rail. A drive motor is fixedly mounted on both the first connecting plate 16 and the second connecting plate 17. A drive gear is fixedly connected to the output shaft of the drive motor. The drive gear meshes with the helical rack mounted on the conveyor frame 3. By driving the drive gear to rotate through the drive motor, the first connecting plate 16 and the second connecting plate 17 can slide horizontally on the conveyor frame 3, thereby moving the feeding device, the mixing device, and the picking device in the horizontal direction.

[0058] In another embodiment, the drive assembly may also include a lead screw rotatably mounted on the upper crossbar of the conveyor frame 3. One end of the lead screw is connected to a drive motor, which is fixedly mounted on the conveyor frame 3. Lead screw nuts are provided on both the first connecting plate 16 and the second connecting plate 17. The lead screw nuts are threadedly connected to the lead screw. The rotation of the lead screw can drive the first connecting plate 16 and the second connecting plate 17 to slide horizontally on the conveyor frame 3.

[0059] Furthermore, such as Figure 6 As shown, the feeding device includes a first support frame 18, which is fixedly mounted on a first connecting plate 16. A first sliding rod 19 is vertically slidable on the first support frame 18, and a connecting frame 20 is provided at the lower end of the first sliding rod 19. A feeding component is provided on the connecting frame 20. In this embodiment, the feeding device can slide horizontally on the conveyor frame 3 following the first connecting plate 16. During the brake pad production process, the feeding device can be moved to the batching mechanism 58. The batching mechanism 58 conveys the prepared powder to the unloading component in the feeding device for storage. Then, the feeding device slides to the hot press 1 following the first connecting plate 16. The hot press mold on the hot press 1 slides to the outside of the hot press body 14. At this time, the unloading component is located directly above the hot press mold. Therefore, the powder stored in the unloading component can be conveyed to the mold cavity of the hot press mold for pressing. The first sliding rod 19 slides up and down on the first support frame 18 to adjust the height of the unloading component to adapt to the height of the hot press 1 and the batching mechanism 58. By continuously repeating the above steps, continuous production can be achieved.

[0060] Specifically, in order to drive the first sliding rod 19 to slide on the first support frame 18, a rack is fixedly provided on the side wall of the first sliding rod 19, a motor is fixedly provided on the first support frame 18, and a gear is fixedly provided on the output shaft of the motor. The gear meshes with the rack, and the first sliding rod 19 can slide on the first support frame 18 by rotating the gear driven by the motor.

[0061] Furthermore, such as Figure 6 As shown, the material feeding assembly includes a material feeding frame 21, which includes a top plate and a bottom plate arranged in parallel. A material feeding cylinder 22 is fixedly mounted on the material feeding frame 21. The material feeding cylinder 22 is a straight cylindrical structure with both ends extending through it. The material feeding cylinder 22 is located between the top plate and the bottom plate, and its upper and lower ends are fixedly connected to the top plate and the bottom plate, respectively. The top plate and the bottom plate are provided with holes communicating with the material feeding cylinder 22, allowing powder to flow from the material feeding cylinder 22. The material falls from the top of the feeding frame 21. The feeding box 23 is fixedly installed on the top of the feeding frame 21. The feeding box 23 has a funnel-shaped structure and is connected to the feeding cylinder 22. A baffle 24 is also horizontally slidably installed on the feeding frame 21. The baffle 24 has a feeding hole that matches the feeding cylinder 22. When the feeding hole is connected to the feeding cylinder 22, the powder can fall normally. When the feeding hole is separated from the feeding cylinder 22, the baffle 24 can block the feeding cylinder 22. In this embodiment, when the feeding device moves to the feeding mechanism 58 to pick up material, the sliding baffle 24 separates the feeding hole from the feeding cylinder 22. The baffle 24 can close the feeding cylinder 22, and the powder in the feeding mechanism 58 can fall into the feeding box 23 and fall from the feeding box 23 into the feeding cylinder 22. The powder will not fall after falling into the feeding cylinder 22. Then the feeding device moves to the top of the hot press mold on the hot press 1, and the sliding baffle 24 makes the feeding hole coincide with the opening end of the feeding cylinder 22. The powder in the feeding cylinder 22 can fall from the feeding cylinder 22 into the hot press mold.

[0062] It should be noted that an ejector cylinder is fixedly installed on the unloading rack 21. The piston rod of the ejector cylinder is fixedly connected to one end of the baffle 24. The sliding of the baffle 24 on the unloading rack 21 can be driven by the extension and retraction of the piston rod of the ejector cylinder.

[0063] Furthermore, there are two baffles 24, which are slidably disposed on the top plate and bottom plate of the unloading rack 21, respectively. Specifically, the top plate and bottom plate of the unloading rack 21 are provided with horizontal slots, and the baffles 24 are inserted into the slots and can slide horizontally within the slots.

[0064] Furthermore, a vibration motor is also installed on the material feeding rack 21. When material accumulates in the material feeding cylinder 22 or the powder falls slowly, the vibration of the vibration motor can make the powder fall quickly into the mold cavity of the hot press mold to prevent material accumulation.

[0065] Furthermore, such as Figure 7 As shown, the stirring device includes a second support frame 25, which is fixedly mounted on the first connecting plate 16. A second sliding rod 26 slides vertically on the second support frame 25. A stirring plate 27 is fixedly mounted at the lower end of the second sliding rod 26. The stirring plate 27 is horizontally mounted. A plurality of stirring rods 28 are fixedly mounted at the lower end of the stirring plate 27. The positions of the stirring rods 28 correspond one-to-one with the positions of the mold cavities on the hot press mold. In this embodiment, after the feeding assembly conveys the powder into the hot press mold, the first connecting plate 16 slides on the conveyor frame 3 and conveys the stirring device to the top of the hot press mold. The stirring rod 28 is located above the mold cavity of the hot press mold. Then, the second sliding rod 26 slides downward on the second support frame 25, so that the stirring rod 28 is inserted into the powder in the mold cavity of the hot press mold. The first connecting plate 16 moves slightly left and right on the conveyor frame 3, so that the stirring rod 28 can sway left and right in the mold cavity, thereby stirring the powder and making the powder in the mold cavity evenly mixed. At the same time, the powder can also be flattened. After the stirring is completed, the second sliding rod 26 slides upward to separate the stirring rod 28 from the mold cavity, and then the steel back can be grabbed into the mold cavity for pressing.

[0066] Specifically, in order to drive the second sliding rod 26 to slide on the second support frame 25, a rack is fixedly installed on the side wall of the second sliding rod 26, a motor is fixedly installed on the second support frame 25, and a gear is fixedly installed on the output shaft of the motor. The gear and the rack mesh with each other, and the second sliding rod 26 can slide up and down on the second support frame 25 by the motor driving the gear to rotate.

[0067] Furthermore, such as Figure 8 As shown, the material handling device includes a third support frame 29, which is fixedly mounted on the second connecting plate 17. A third sliding rod 30 slides vertically on the third support frame 29. A finished product handling plate 31 is fixedly mounted at the lower end of the third sliding rod 30. The finished product handling plate 31 is horizontally mounted. Multiple finished product electromagnets 32 are provided on the lower end face of the finished product handling plate 31. Each finished product electromagnet 32 ​​corresponds to a mold cavity on the hot pressing mold. In this embodiment, after the brake pads are pressed, the hot press mold on the hot press body 14 slides to the outside of the hot press body 14. By sliding the second connecting plate 17, the material taking device can be moved to the top of the hot press mold. Then, the third sliding rod 30 slides down on the third support frame 29, so that the finished product electromagnet 32 ​​contacts the pressed brake pads. After the finished product electromagnet 32 ​​is energized, it can pick up the brake pads. Then, the second connecting plate 17 slides on the conveyor frame 3, moving the material taking device to the storage box located on the right side of the preheating mechanism. After the finished product electromagnet 32 ​​is de-energized, the brake pads can fall into the storage box for centralized storage.

[0068] Specifically, in order to drive the third sliding rod 30 to slide on the third support frame 29, a rack is fixedly installed on the side wall of the third sliding rod 30, a motor is fixedly installed on the third support frame 29, and a gear is fixedly installed on the output shaft of the motor. The gear and the rack mesh with each other, and the third sliding rod 30 can slide up and down on the third support frame 29 by the motor driving the gear to rotate.

[0069] Furthermore, such as Figure 8 As shown, a cleaning device is also provided on the second connecting plate 17. The cleaning device includes a fourth support frame 36, which is fixedly mounted on the second connecting plate 17. A fourth sliding rod 37 slides vertically on the fourth support frame 36. A cleaning box 38 is fixedly mounted at the lower end of the fourth sliding rod 37. The cleaning box 38 is a box-shaped structure with an open bottom. A brush is provided inside the cleaning box 38. The lower end surface of the brush is flush with the lower end surface of the cleaning box 38 or the lower end surface of the brush is lower than the lower end surface of the cleaning box 38. In this embodiment, after the powder in the hot press mold cavity is stirred evenly and spread out, in order to avoid powder residue on the upper end of the hot press mold, the cleaning device moves above the hot press mold when the second connecting plate 17 moves on the conveyor frame 3, and the fourth sliding rod 37 slides downward on the second support frame. The lower end face of the cleaning box 38 abuts against the upper end face of the hot press mold. Through the sliding action of the second connecting plate 17 on the conveyor frame 3, the brush in the cleaning box 38 can clean the powder residue on the upper end face of the hot press mold. After cleaning, the second connecting plate 17 slides on the conveyor frame 3 to separate the cleaning device from the hot press mold.

[0070] Specifically, in order to drive the fourth sliding rod 37 to slide on the fourth support frame 36, a rack is fixedly installed on the side wall of the fourth sliding rod 37, a motor is fixedly installed on the fourth support frame 36, and a gear is fixedly installed on the output shaft of the motor. The gear and the rack mesh with each other, and the fourth sliding rod 37 can slide up and down on the fourth support frame 36 by the motor driving the gear to rotate.

[0071] Furthermore, such as Figure 9As shown, the steel backing feeding mechanism includes a ground rail 33, which is fixedly installed on one side of the hot press 1. A base 34 is slidably installed on the ground rail 33. A feeding component 59 is rotatably installed on the base 34 for placing the steel backing. A positioning component 60 is also installed on the base 34 for positioning the steel backing. A picking component 61 is provided between the feeding component 59 and the positioning component 60. A robot arm 35 is also installed on the base 34 for placing the steel backing onto the hot press mold. In this embodiment, after adding powder to the cavity of the hot press mold, stirring, spreading, and cleaning, the base 34 on the ground rail 33 slides along the ground rail 33, so that the base 34 moves to the hot press machine 1 relative to the hot press mold after cleaning. The material picking component 61 picks up the steel back stored on the feeding component 59 and places it on the positioning component 60 for repositioning. After positioning, the robot arm 35 picks up the steel back on the positioning component 60 and places it in the cavity of the hot press mold. The steel back is above the powder. Then the hot press machine 1 presses it so that the powder and the steel back are pressed together. After pressing, the material picking device on the conveyor frame 3 picks up the steel back and transfers it to the storage box.

[0072] It should be noted that a helical rack is fixedly installed on the ground rail 33 along the length direction, a drive motor is fixedly installed on the base 34, and a drive gear is fixedly installed on the output shaft of the drive motor. The drive gear meshes with the helical rack. After the drive motor starts, it drives the drive gear to rotate, thereby enabling the base 34 to slide on the ground rail 33.

[0073] In another embodiment, a lead screw can be rotatably mounted on the ground rail 33. One end of the lead screw is connected to a motor, which is fixedly mounted on the ground rail 33. A lead screw nut is mounted on the base 34. The lead screw nut is threadedly connected to the lead screw on the ground rail 33. The rotation of the lead screw can drive the lead screw nut and the base 34 to slide on the ground rail 33.

[0074] Furthermore, such as Figure 10As shown, the feeding assembly 59 includes a rotating plate 39, and a motor is fixedly mounted on the base 34. The output shaft of the motor is fixedly connected to the center of the rotating plate 39. After the motor starts, the output shaft rotates, which can drive the rotating plate 39 to rotate on the base 34. The motor is a servo motor, thereby precisely controlling the rotation angle. Multiple storage plates 40 are also provided at the edge of the rotating plate 39. The multiple storage plates 40 are evenly arranged along the circumference and are used to store stacked steel backs. Multiple side plates 4 are evenly arranged along the circumference on the rotating plate 39. 1. The side plates 41 are vertically or inclined towards the center of the rotating plate 39. The number of side plates 41 is the same as the number of shelf plates 40, and the side plates 41 and shelf plates 40 correspond one-to-one. The side edge of the shelf plate 40 abuts against the side plate 41. Two clamping plates 42 are also slidably arranged on each side plate 41. The two clamping plates 42 are located on both sides of the shelf plate 40. The two clamping plates 42 can slide towards each other or away from each other, thereby clamping the steel back stacked on the shelf plate 40, and can accommodate more models of steel back. In this embodiment, since there are multiple hot presses 1, multiple hot presses 1 can work simultaneously to produce brake pads. Multiple hot presses 1 can press brake pads of various specifications and models. During the pressing process, the steel backing needs to be transported to the hot press mold of the hot press 1. The feeding assembly 59 is equipped with multiple placement plates 40, each of which can hold a steel backing of a specific specification and model. During the pressing process, the base 34 slides on the ground rail 33. When the base 34 slides to the corresponding hot press 1, the rotating plate 39 rotates, causing the placement plate 40 holding the corresponding steel backing to rotate to the material picking assembly 61. The material picking assembly 61 removes the steel backing and places it at the positioning assembly 60 for positioning. After positioning, the robot can remove the steel backing and place it on the hot press mold for pressing. By continuously sliding the base 34 on the ground rail 33 for position adjustment and by rotating the rotating plate 39 on the base 34, multiple hot presses 1 can be supplied with steel backing, enabling them to work simultaneously.

[0075] It should be noted that multiple bidirectional screws 43 are rotatably arranged on the rotating plate 39. Two sets of external threads with different directions are symmetrically arranged on the bidirectional screws 43. The multiple bidirectional screws 43 are evenly arranged along the circumferential direction. The positions of the bidirectional screws 43 and the clamping plates 42 are opposite. A handwheel is fixedly arranged at one end of the bidirectional screws 43. Two connecting blocks 44 are threadedly connected to the bidirectional screws 43. The two connecting blocks 44 are located at the two sets of external threads of the bidirectional screws 43, and the two connecting blocks 44 are fixedly connected to the two clamping plates 42 located on the same side plate 41. Therefore, when the bidirectional screws 43 are rotated, the two clamping plates 42 on the same side plate 41 can be driven to move in the same or opposite directions to clamp the steel back on the shelf 40.

[0076] Furthermore, such as Figure 12As shown, a lifting assembly is also provided on the base 34 to drive the storage plate 40 to rise and fall on the side plate 41. The lifting assembly includes a stand 50 fixedly mounted on the base 34. A screw is rotatably mounted on the stand 50 in the vertical direction. A lifting plate 51 slides vertically on the stand 50. The lifting plate 51 is located below the storage plate 40. A screw nut is provided on the lifting plate 51. The screw nut is threadedly connected to the screw on the stand 50. During the rotation of the screw, it can drive the screw nut and the lifting plate 51 connected to the screw nut to rise or fall. Since the lifting plate 51 is located below the storage plate 40, it can also drive the storage plate 40 to rise or fall. The steel back stacked on the storage plate 40 will decrease in height as it is continuously removed. When it decreases to a certain height, the material picking assembly 61 cannot pick up the material. Therefore, by raising the lifting plate 51, the storage plate 40 is raised, thereby increasing the height of the steel back and enabling the material picking assembly 61 to pick up the material normally.

[0077] It should be noted that a slot is provided at the edge of the base plate 34, and a block is fixedly provided at the bottom of the shelf 40. When the shelf 40 is at its lowest position, the block is inserted into the slot, so that the shelf 40 can be fixedly placed on the base plate. When the lifting plate 51 drives the shelf 40 to rise, the block can disengage from the slot and will not hinder the rise of the shelf 40.

[0078] Furthermore, such as Figure 11 As shown, the material picking assembly 61 includes a picking frame 45 fixedly mounted on the base 34. The picking frame 45 is located above the lifting assembly. A moving frame 46 slides horizontally on the picking frame 45, and a connecting rod 47 slides vertically on the moving frame 46. A steel back picking plate 48 is fixedly mounted at the bottom of the connecting rod 47, and a steel back electromagnet 49 is mounted at the bottom of the steel back picking plate 48. When the picking assembly 61 picks up the steel back from the feeding assembly 59, the moving frame 46 first slides horizontally to the top of the steel back in the feeding assembly 59. Then, the connecting rod 47 slides downward to make the steel back electromagnet 49 contact the steel back. After the steel back electromagnet 49 is energized, it can pick up the steel back. Then, the connecting rod 47 slides upward to pick up the steel back. Finally, the moving frame 46 slides horizontally to transfer the steel back to the positioning assembly 60. After the steel back electromagnet 49 is de-energized, the steel back falls onto the positioning assembly 60 for positioning.

[0079] Specifically, in order to make the movable frame 46 slide on the picking frame 45, a drive wheel and a driven wheel are rotatably provided on the picking frame 45. A motor is also fixedly provided on the picking frame 45. The motor is connected to the drive wheel for transmission. The center line connecting the drive wheel and the driven wheel is horizontal. A synchronous belt is wound between the drive wheel and the driven wheel. The movable frame 46 is fixedly connected to the synchronous belt. When the synchronous belt rotates on the drive wheel and the driven wheel, it can drive the movable frame 46 to slide horizontally.

[0080] Similarly, in order to make the connecting rod 47 slide vertically on the movable frame 46, a drive wheel and a driven wheel are rotatably provided on the movable frame 46. A motor is fixedly provided on the movable frame 46, and the motor is connected to the drive wheel for transmission. The center line connecting the drive wheel and the driven wheel is vertical. A synchronous belt is wound between the drive wheel and the driven wheel. The synchronous belt is fixedly connected to the connecting rod 47. When the synchronous belt rotates, it can drive the connecting rod 47 to slide in the vertical direction.

[0081] Furthermore, such as Figure 13 As shown, the positioning assembly 60 includes a positioning frame 52 fixedly mounted on the base 34, and a positioning plate 53 mounted on the positioning frame 52. A first positioning strip 54 and a second positioning strip 55 are fixedly mounted on the upper surface of the positioning plate 53. The first positioning strip 54 and the second positioning strip 55 are vertically mounted at the edge of the positioning plate 53. A first clamping strip 56 and a second clamping strip 57 are also slidably mounted on the positioning plate 53. The first clamping strip 56 is parallel to the first positioning strip 54, and the second clamping strip 57 is parallel to the second positioning strip 55. When the material handling assembly 61 picks up the material... After the steel back is gripped on the feeding assembly 59, the material handling assembly places the steel back on the positioning plate 53. The first clamping bar 56 and the second clamping bar 57 slide towards the steel back. The first clamping bar 56, the second clamping bar 57, the first positioning bar 54, and the second positioning bar 55 clamp the four sides of the steel back, which can play a positioning role. After positioning is completed, the first clamping bar 56 and the second clamping bar 57 reset. The robot arm 35 grips the positioned steel back and places it in the hot press mold of the hot press machine 1 for pressing. The robot arm 35 is a SCARA robot arm.

[0082] More specifically, the bottom of the positioning plate 53 is provided with two sets of power components for driving the first clamping bar 56 and the second clamping bar 57 to slide on the positioning plate 53. The power components include a drive wheel and a driven wheel that are rotatably arranged. The drive wheel is driven to rotate by a motor that is fixedly arranged on the positioning plate 53. A belt is wound between the drive wheel and the driven wheel. A connecting piece is fixedly arranged on the belt. The two connecting pieces are fixedly connected to the first clamping bar 56 and the second clamping bar 57 respectively. The first clamping bar 56 and the second clamping bar 57 can be driven to slide on the positioning plate 53 by the belt rotating between the drive wheel and the driven wheel.
