Description

Technical Field

[0001] This invention relates to the field of brake pad manufacturing technology, specifically to an automatic brake pad pressing device. Background Technology

[0002] Brake pads, also called brake discs, consist of a cast steel backing component and a friction pad pressed onto it. They are connected to the hydraulic system through pin holes in the backing component. The braking effect is achieved by controlling the action of the brake pads against the brake disc on the wheel hub through the hydraulic system.

[0003] In the brake pad pressing process, granular or powdered lining material is combined with a backing steel and pressed into a unified whole through heating and pressure. However, traditional equipment used to produce brake pads has a low degree of automation and requires manual operation by workers. It is difficult to achieve stable and precise feeding of the backing steel and lining material, and it is difficult to quickly complete the heating and pressing of the backing steel and lining material according to the processing flow, as well as the heat dissipation, inspection, and unloading of the finished product. This results in limited brake pad production efficiency. Since each process requires manual operation, there is a large operational error, making it difficult to guarantee the production accuracy of brake pads. Summary of the Invention

[0004] To address the aforementioned shortcomings in existing technologies, the present invention aims to provide an automatic feeding brake pad pressing device that can effectively improve the automation level of brake pad pressing production, thereby increasing brake pad production efficiency. It can achieve automatic feeding of various materials, thus replacing manual feeding by workers and effectively improving brake pad production efficiency and precision.

[0005] The technical solution adopted by the present invention to achieve the above objectives is as follows: an automatic brake pad pressing device, comprising a worktable and a six-position indexing plate and a three-position indexing plate mounted on the worktable. The six-position indexing plate is cyclically arranged with a back steel feeding station, a back steel heating station, an upper pressing station, a heat dissipation station, an inspection station, and a finished product unloading station. A back steel feeding mechanism is installed at the back steel feeding station, a back steel heating mechanism is installed at the back steel heating station, an upper pressing mechanism is installed at the upper pressing station, a heat dissipation mechanism is installed at the heat dissipation station, and a heat dissipation mechanism is installed at the inspection station. Equipped with an optical inspection mechanism, the finished product unloading station is equipped with a finished product unloading mechanism; the three-station indexing plate and the six-station indexing plate are linked through a transmission mechanism. The three-station indexing plate is cyclically arranged with a lining material feeding station, a lining material heating station, and a lower layer pressing station. The upper layer pressing station and the lower layer pressing station are arranged in the same vertical direction. The lining material feeding station is equipped with a quantitative feeding box, the lining material heating station is equipped with a lining material heating mechanism, and the lower layer pressing station is equipped with a lower layer pressing mechanism.

[0006] When processing brake pads, the steel backing is fed to the six-position indexing plate through the back steel feeding mechanism, and powdered and granular lining material is fed to the three-position indexing plate through the quantitative feeding box.

[0007] Control the six-position indexing plate to rotate 1 / 6 of a circle, and control the three-position indexing plate to rotate 1 / 3 of a circle, so that the steel backing and lining material are rotated to the steel backing heating station and the lining material heating station respectively for heating.

[0008] The six-position indexing plate is rotated by 1 / 6 of a circle, and the three-position indexing plate is rotated by 1 / 3 of a circle. The heated steel backing and lining are rotated to the upper and lower pressing positions respectively, and kept vertically opposite each other. With the cooperation of the upper and lower pressing mechanisms, the steel backing and lining are pressed together to form a brake pad.

[0009] Then, the six-position indexing plate is rotated by 1 / 6 of a circle, so that the pressed brake pads are cooled by the heat dissipation mechanism and their temperature is reduced to room temperature.

[0010] The six-position indexing plate is rotated 1 / 6 of a circle again, and the optical inspection mechanism performs optical inspection on the cooled brake pads to determine whether they are qualified.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figure 1-16 The operating principle of the present invention and the specific structure of each component will be explained in conjunction with the following embodiments.

[0051] Example 1

[0052] An automatic brake pad pressing device includes a worktable 1 and a six-position indexing plate 2 and a three-position indexing plate 3 mounted on the worktable 1. The six-position indexing plate 2 has a cyclically arranged back steel feeding station, a back steel heating station, an upper pressing station, a heat dissipation station, an inspection station, and a finished product unloading station. A back steel feeding mechanism 4 is installed at the back steel feeding station, a back steel heating mechanism 5 is installed at the back steel heating station, an upper pressing mechanism 6 is installed at the upper pressing station, a heat dissipation mechanism 7 is installed at the heat dissipation station, and an optical inspection mechanism 8 is installed at the inspection station. The finished product unloading station... The material feeding station is equipped with a finished product unloading mechanism 9; the three-station indexing plate 3 and the six-station indexing plate 2 are linked through a transmission mechanism. The three-station indexing plate 3 is cyclically arranged with a lining material feeding station, a lining material heating station, and a lower layer pressing station. The upper layer pressing station and the lower layer pressing station are arranged in the same vertical direction. The lining material feeding station is equipped with a quantitative feeding box 10. The lining material heating station is equipped with a lining material heating mechanism 11. The lower layer pressing station is equipped with a lower layer pressing mechanism 12. The lower layer pressing mechanism 12 and the upper layer pressing mechanism 6 work together to achieve the pressing and forming function of the back steel and the lining material.

[0053] When processing brake pads, the steel backing 13 is conveyed to the six-position indexing plate 2 through the backing steel feeding mechanism 4, and powdered and granular lining material is conveyed to the three-position indexing plate 3 through the quantitative feeding box 10.

[0054] Control the six-position indexing plate 2 to rotate 1 / 6 of a circle, and control the three-position indexing plate 3 to rotate 1 / 3 of a circle, so that the steel backing 13 and the lining material are rotated to the steel backing heating station and the lining material heating station respectively for heating.

[0055] The six-position indexing plate 2 is rotated by 1 / 6 of a circle, and the three-position indexing plate 3 is rotated by 1 / 3 of a circle. The heated steel back 13 and the lining are rotated to the upper pressing station and the lower pressing station, respectively, and kept vertically opposite each other. With the cooperation of the upper pressing mechanism 6 and the lower pressing mechanism 12, the steel back 13 and the lining are pressed together to form a brake pad.

[0056] Then, the six-position indexing plate 2 is rotated by 1 / 6 of a circle, so that the pressed brake pads are cooled by the heat dissipation mechanism 7, and their temperature is reduced to room temperature.

[0057] The six-position indexing plate 2 is rotated by 1 / 6 of a circle again, and the optical inspection mechanism 8 performs optical inspection on the cooled brake pads to determine whether they are qualified. Finally, the six-position indexing plate 2 is rotated by 1 / 6 of a circle, and the finished product unloading mechanism 9 outputs the inspected brake pads.

[0058] By continuing to operate according to the above scheme, brake pads can be produced quickly and with high efficiency and automation.

[0059] Example 2

[0060] Based on Example 1, the following description is made of the six-station indexing plate 2, the three-station indexing plate 3 and their linkage relationship to ensure that their normal operation can realize each processing step.

[0061] In some implementations, in order to ensure the stable operation of the six-station indexing plate 2 and thus complete the sequential feeding and heating of the steel backing 13, the pressing and molding of the steel backing 13 and the lining 14, the heat dissipation of the finished product, the optical inspection of the finished product, and the unloading and output of the finished product, the following technical solutions for the six-station indexing plate 2 are provided.

[0062] The six-station indexing plate 2 includes a first fixed plate 15, a first turntable 16, a first rotating sleeve 17, a first fixed shaft 18, and a first motor 19. The first fixed shaft 18 is fixedly connected to the worktable 1 and arranged vertically. The first rotating sleeve 17 is rotatably installed around the first fixed shaft 18, and the first motor 19 is poweredly connected to the first rotating sleeve 17. The shafts of the first fixed plate 15 and the first turntable 16 are fixedly connected to the top ends of the first fixed shaft 18 and the first rotating sleeve 17, respectively. The first fixed plate 15 is arranged above the first turntable 16. Six sets of first processing seats 20 are evenly fixed on the first turntable 16 and arranged around the first fixed plate 15. The first processing seat 20 is provided with a first processing groove 21. The back steel heating mechanism 5, the upper pressing mechanism 6, and the optical inspection mechanism 8 are installed on the first fixed plate 15.

[0063] The first processing groove 21 in each group of first processing seats 20 has a through hole structure, that is, both the upper and lower ends of the first processing groove 21 are connected to the external environment. In order to ensure that the steel back 13 can be placed in the first processing groove 21 and stably pressed into a complete brake pad, the internal size of the upper half of the first processing groove 21 is designed to be slightly larger than the internal size of the lower half. That is, the inner side wall of the upper half of the first processing groove 21 is nested and matched with the outer side wall of the steel back 13 of the brake pad, and the lower half of the first processing groove 21 abuts against the edge of the steel back 13. At the same time, the lower half of the first processing part can ensure that the lower pressing mechanism 12 extends into it and stably presses the lining part 14 onto the steel back 13.

[0064] To ensure that the first rotating sleeve 17 and the first turntable 16 can rotate stably driven by the first motor 19, so that the back steel loading station, the back steel heating station, the upper layer pressing station, the heat dissipation station, the inspection station, and the finished product unloading station can be sequentially passed through the specific first processing groove 21, thereby realizing various processing functions, a transmission gear 22 is fixedly connected to the periphery of the first rotating sleeve 17, and the first motor 19 is fixedly installed on the worktable 1, and a drive gear 23 that meshes with the transmission gear 22 is fixedly connected to the rotating shaft of the first motor 19.

[0065] When the first motor 19 drives the drive gear 23 to rotate, it can drive the transmission gear 22 and the first rotating sleeve 17 and the first turntable 16 fixed to the transmission gear 22 to rotate stably, thereby enabling each first processing seat 20 on the first turntable 16 to sequentially pass through the back steel feeding mechanism 4, the back steel heating mechanism 5, the upper layer pressing mechanism 6, the heat dissipation mechanism 7, the optical inspection mechanism 8, and the finished product unloading mechanism 9 to complete the corresponding process steps.

[0066] To ensure that the first motor 19 can be stably installed on the workbench 1 without interfering with the normal operation of the six-position indexing plate 2, the first motor 19 is arranged horizontally on the lower side of the first turntable 16. Therefore, the drive gear 23 and the transmission gear 22 are both bevel gears and are vertically distributed.

[0067] Based on the above technical solution for the six-station indexing plate 2, in order to ensure the stable operation of the three-station indexing plate 3, and to complete the quantitative feeding and heating of the lining material, and the pressing and molding of the lining material 14 and the steel backing 13, the following technical solution for the three-station indexing plate 3 and the transmission mechanism is provided.

[0068] The three-station indexing plate 3 includes a second fixed plate 24, a second turntable 25, a second rotating sleeve 26, and a second fixed shaft 27. The second fixed shaft 27 is fixedly connected to the worktable 1 and arranged vertically. The second rotating sleeve 26 is rotatably installed around the second fixed shaft 27. The axes of the second fixed plate 24 and the second turntable 25 are fixedly connected to the top ends of the second fixed shaft 27 and the second rotating sleeve 26, respectively. The second fixed plate 24 is arranged above the second turntable 25. Three sets of second processing seats 28 arranged around the second fixed plate 24 are evenly fixedly connected to the second turntable 25. Each second processing seat 28 has two sets of symmetrically arranged second processing grooves 29. A sliding pad 30 is slidably installed in the second processing groove 29. A lining heating mechanism 11 is installed on the second fixed plate 24.

[0069] The second processing groove 29 has a through-hole structure design, that is, the upper and lower ends of the second processing groove 29 are connected to the external environment, which allows the lining heating mechanism 11 to extend into the second processing groove 29 from the top to heat the lining, and allows the lower layer pressing mechanism 12 to extend into the second processing groove 29 from the bottom, and press the lining with the help of the sliding pad 30, and realize the combination of the lining part 14 and the steel back 13 at the lower layer pressing station and the upper layer pressing station.

[0070] The bottom opening of each group of second processing tanks 29 is designed to be narrow, which can ensure that the sliding pad 30 is stably installed in it and will not slip off the bottom of the second processing tank 29. Powder or granular lining material is added to the two groups of second processing tanks 29 opened in each group of second processing seats 28, and the bottom of the second processing tank 29 is supported by the sliding pad 30, which can prevent the lining material from spilling out of the second processing tank 29.

[0071] The second turntable 25 drives each group of second processing seats 28 to pass sequentially through the quantitative feeding box 10, the lining heating mechanism 11, and the lower pressing mechanism 12 to complete various processes such as quantitative input of lining material, heating of lining material 14, and pressing of lining material and steel backing 13 to form a complete brake pad.

[0072] The transmission mechanism includes a first synchronous pulley 31, a second synchronous pulley 32, and a synchronous belt. The first synchronous pulley 31 is fixed to the first rotating sleeve 17, the second synchronous pulley 32 is fixed to the second rotating sleeve 26, and the synchronous belt is wound between the first synchronous pulley 31 and the second synchronous pulley 32 and is in a taut state.

[0073] When the first motor 19 drives the first rotating sleeve 17 to rotate, the combination of the first synchronous pulley 31, the second synchronous pulley 32 and the synchronous belt can drive the second rotating sleeve 26 to rotate, thereby driving the second turntable 25 fixed to the second rotating sleeve 26 and each of the second processing seats 28 on the second turntable 25 to rotate stably, realizing the linkage operation of the six-position indexing plate 2 and the three-position indexing plate 3.

[0074] Since the six-position indexing plate 2 has six sets of processing stations and the three-position indexing plate 3 has three sets of processing stations, in order to ensure that when the six-position indexing plate 2 rotates by 1 / 6 of a circumference and the first processing seat 20 on the upstream side moves to the upper pressing station, the three-position indexing plate 3 rotates by 1 / 3 of a circumference and the second processing seat 28 on the upstream side moves to the lower pressing station, so that the corresponding first processing seat 20 and second processing seat 28 are vertically aligned, and the upper pressing mechanism 6 and the lower pressing mechanism 12 work together to press out the finished brake pads, the transmission ratio of the first synchronous belt and the second synchronous belt is designed to be 2:1 so that the six-position indexing plate 2 and the three-position indexing plate 3 can achieve stable operation with an angular velocity ratio of 2:1.

[0075] Since the quantitative feeding box 10 and the lower pressing mechanism 12 are installed on the workbench 1, in order to avoid spatial interference between the synchronous belt and the quantitative feeding box 10 and the lower pressing mechanism 12, a guide wheel 33 is also rotatably installed on the workbench 1. The synchronous belt can avoid interference during operation by passing around the guide wheel 33 and keeping it taut.

[0076] Example 3

[0077] Based on Example 1, the back steel feeding mechanism 4 and its operating principle are described below. An implementation method for applying the back steel feeding mechanism 4 to the six-station indexing plate 2 is also provided. The structural form and operating principle of the finished product unloading mechanism 9 are also provided. The quantitative feeding box 10 and its operating principle are described below. An implementation method for applying the quantitative feeding box 10 to the three-station indexing plate 3 is also provided.

[0078] In some implementations, to ensure that the steel backing feeding mechanism 4 can stably transport the steel backing 13 to the steel backing feeding station on the six-station indexing plate 2, the following technical solution for the steel backing feeding mechanism 4 is provided.

[0079] The steel backing feeding mechanism 4 includes a belt feeding module, a linear travel module, and a first clamping assembly. The belt feeding module is installed on the workbench 1, and a hopper plate 34 is installed on the belt feeding module. Storage slots 35 are evenly opened on the hopper plate 34. The linear travel module is installed between the belt feeding module and the steel backing feeding mechanism 4, and the linear travel module and the belt feeding module are arranged perpendicularly. The first clamping assembly is installed on the movable part of the linear travel module.

[0080] The belt feeding module includes a drive roller 36, a driven roller 37, a transmission belt 38, and a second motor 39. The drive roller 36 and the driven roller 37 are arranged on the same horizontal plane. The transmission belt 38 is wound around the drive roller 36 and the driven roller 37 and is arranged in a taut state. The second motor 39 is powered by the drive roller 36 and drives the drive roller 36 to rotate stably. The transmission belt, the drive roller 36, and the driven roller 37 are all provided with intermeshing teeth, which can prevent the drive roller 36, the driven roller 37, and the transmission belt 38 from slipping during operation and ensure the accuracy of transmission by the transmission belt 38.

[0081] To ensure the stability of the belt feeding module installation, a mounting frame is installed on the workbench 1. The drive roller 36 and the driven roller 37 are both rotatably mounted on the mounting frame. The second motor 39 is fixedly mounted on the mounting frame, and a drive sprocket is fixedly connected to the shaft of the second motor 39. A transmission sprocket is fixedly connected to the shaft of the drive roller 36. The drive sprocket and the transmission sprocket are connected to a chain for chain drive. When the second motor 39 is working, the combination of the drive sprocket and the transmission sprocket drives the drive roller 36 to rotate stably, which in turn drives the transmission belt 38 to run stably in conjunction with the driven roller 37.

[0082] The hopper plate 34 is fixedly installed on the upper surface of the transmission belt 38. By controlling the forward and reverse rotation of the second motor 39, the position of each storage slot 35 on the hopper plate 34 can be adjusted. The steel back 13 is nested in the storage slot 35. The steel back 13 in the storage slot 35 at a specific position is clamped by the linear travel module and the first clamping assembly on it and transported along the linear module to the steel back loading station on the six-position indexing plate 2.

[0083] Since the belt feeding module and the linear travel module are vertically distributed and work together, the position of each steel back 13 on the hopper plate 34 can be adjusted so that it can be stably clamped by the first clamping assembly.

[0084] The linear travel module includes a linear slide 40, a slide block 41, a lead screw 42, and a third motor 43. The lead screw 42 is rotatably mounted in the linear slide 40. The third motor 43 is fixedly mounted at the end of the linear slide 40, and the shaft of the third motor 43 is fixedly connected to the end of the lead screw 42. The slide block 41 is slidably mounted on the linear slide and is screwed to the lead screw 42. When the third motor 43 drives the lead screw 42 to rotate, it can drive the slide block 41 to move linearly along the linear slide 40, thereby driving the first clamping assembly mounted on the slide block 41 to move, so as to transport the clamped steel back 13.

[0085] In some embodiments, in order to ensure that the finished product unloading mechanism 9 can stably output the pressed brake pad finished product, the same components as the back steel feeding mechanism 4 can be used to realize the finished product unloading function. That is, the finished product unloading mechanism 9 includes at least a linear travel module and a first clamping assembly, and one end of the linear travel module is mounted at the finished product unloading station. The first clamping assembly clamps one side of the produced brake pad steel back 13 and drives it to be output through the linear travel module.

[0086] Based on the above implementation method, in order to ensure that the linear travel module involved in the steel backing feeding mechanism 4 and the finished product unloading mechanism 9 is erected at a specific height so that the first clamping assembly can stably transport the steel backing 13 or the finished brake pad, a support frame is erected on the workbench 1, and the linear travel module is fixedly installed on the support frame.

[0087] The first clamping assembly includes a first telescopic cylinder 44, a lifting seat 45, a bonding plate 46, and a lifting plate 47. The first telescopic cylinder 44 is vertically fixed to the movable part of the linear travel module. The lifting seat 45 is fixed to the movable part of the first telescopic cylinder 44. The bonding plate 46 is fixedly connected to the lower side of the lifting seat 45. The lifting plate 47 is arranged between the lifting seat 45 and the bonding plate 46, and the lifting plate 47 is connected to the bonding plate 46 through a linear motor 48. The bonding plate 46 has multiple sets of telescopic through holes, and the lifting plate 47 is fixedly installed with multiple sets of electromagnets 49 that pass through the telescopic through holes.

[0088] The first telescopic cylinder 44 is fixedly installed on the lower surface of the slide block 41. In order to ensure that the lifting seat 45 is driven to rise and fall stably by the first telescopic cylinder 44, a vertically arranged guide column is fixedly connected to the slide block 41, and the guide column is slidably inserted into the lifting seat 45.

[0089] The bonding plate 46 is designed to fit against the outer surface of the steel backing 13. A pin hole 50 is provided on the steel backing 13. The telescopic through-hole on the bonding plate 46 is arranged opposite to the pin hole 50. When the linear motor 48 drives the lifting plate 47 to descend, it drives each electromagnet 49 to extend out of the telescopic through-hole and insert into the pin hole 50 of the steel backing 13, thus lifting the steel backing 13 and achieving a fixed clamping effect. To ensure that the lifting plate 47 can be stably arranged between the lifting seat 45 and the bonding plate 46 without affecting the lifting movement of the lifting plate 47, the lifting seat 45 and the bonding plate 46 are fixedly connected by connecting columns.

[0090] When the first clamping assembly cancels the clamping effect on the steel back 13, the control lifting plate 47 drives the electromagnet 49 to move upward and retract into the telescopic through hole, and at the same time cancels the power supply to the electromagnet 49, thereby canceling the clamping effect on the steel back 13.

[0091] When the first clamping assembly in the steel backing feeding mechanism 4 clamps the steel backing 13 and moves it to the steel backing feeding station on the six-station indexing plate 2, the first telescopic cylinder 44 drives the bonding plate 46 and the steel backing 13 fixed below the bonding plate 46 to move down and install it in the first processing groove 21. When the finished product unloading mechanism 9 takes out the finished product that has been pressed at the finished product unloading station, the unloading process is completed by using the reverse operation process of the steel backing feeding mechanism 4.

[0092] Based on the above technical solution for the three-station indexing plate 3, the following technical solution for the quantitative feeding box 10 is provided to input equal amounts of granular or powdered lining material into the two sets of second processing slots 29 on the second processing seat 28.

[0093] The quantitative feeding box 10 includes a storage box 51, a feeding pipe 52, a flow meter 53, and a switch valve 54. The quantitative feeding box 10 is installed on the upper side of the second turntable 25. The feeding pipe 52 includes two sets arranged vertically side by side, and the two sets of feeding pipes 52 are connected to the bottom of the storage box 51. The flow meter 53 and the switch valve 54 are installed on each set of feeding pipes 52.

[0094] To ensure that the storage box 51 can be stably installed on the workbench 1, the bottom of the processing box is fixedly installed on the workbench 1 by support legs. When the second processing seat 28 and the second processing groove 29 therein are rotated to the lining feeding position, the bottom ends of the two sets of feeding pipes 52 are vertically opposite to the two sets of second processing grooves 29 respectively. The flow meter 53 is a solid powder flow meter 53, and the switch valve 54 is an electromagnetic switch valve 54. The flow meter 53 detects the flow rate of the granular and powdered lining material output from the corresponding feeding pipe 52. When the flow rate reaches the set level, the switch valve 54 is closed, which can input a certain amount of lining material into the second processing groove 29.

[0095] Example 4

[0096] Based on Examples 1-2, the first heating mechanism, the second heating mechanism and their operating principles are described below, and implementation methods for their operation in conjunction with the six-position indexing plate 2 and the three-position indexing plate 3 are provided.

[0097] Based on the above technical solutions regarding the six-station distribution plate and the three-station indexing plate 3, the following technical solutions are provided regarding the back steel heating mechanism 5 and the lining heating mechanism 11 to ensure stable heating of the steel back 13 and the lining part 14 to be pressed and formed.

[0098] The back steel heating mechanism 5 includes a first lifting module and a first heating seat 55. The first lifting module is fixedly installed on the first fixed plate 15, and the first heating seat 55 is fixedly installed on the movable part of the first lifting module. The first heating seat 55 is nested and matched with the first processing groove 21. The lining heating mechanism 11 includes a second lifting module and a second heating seat 56. The second lifting module is fixedly installed on the second fixed plate 24. The second heating seat 56 includes two symmetrically arranged sets, and the two sets of second heating seats 56 are fixedly installed on the movable part of the second lifting module. The second heating seat 56 is nested and matched with the second processing groove 29.

[0099] When the steel back 13 is installed in the first processing groove 21 at the steel back loading station by the steel back loading mechanism 4, the six-station indexing plate 2 rotates by 1 / 6 of a circumference angle so that the steel back 13 moves to the steel back heating station. The first lifting module drives the first heating seat 55 to move down so that the first heating seat 55 extends into the corresponding first processing groove 21 and heats the steel back 13 therein.

[0100] When a specific amount of granular or powdered lining material is fed into the two sets of second processing slots 29 at the lining material feeding station by the quantitative feeding box 10, the three-station indexing plate 3 rotates by 1 / 3 of a circumference angle so that the lining material moves to the lining material heating station. The second lifting module drives the second heating seat 56 to move downward, so that the two sets of second heating seats extend into the two corresponding sets of second processing slots 29 respectively, and heat the lining material therein.

[0101] The first and second lifting modules can be products with identical structures. Both include a mounting pad 57, a second telescopic cylinder 58, a lifting top seat 59, and a mounting base 60. The mounting pad 57 is fixedly mounted on the first fixed plate 15 or the second fixed plate 24. The second telescopic cylinder 58 is fixedly mounted on the mounting pad 57 and arranged vertically. The lifting top seat 59 is fixedly connected to the movable end of the second telescopic cylinder 58. During the telescopic movement of the second telescopic cylinder 58, it can drive the lifting top seat 59 to rise and fall synchronously. To ensure that the lifting top seat 59 rises and falls stably in the vertical direction, a guide rod is fixedly connected to the mounting pad 57 and slidably inserted into the lifting top seat 59. The mounting base 60 is arranged below the lifting top seat 59 and is fixedly connected to the lifting top seat 59 through a connecting rod. The first heating seat 55 or the second heating seat 56 is fixedly mounted on the lower surface of the mounting base 60.

[0102] When the second telescopic cylinder 58 extends or retracts, it can drive the mounting base 60 and the first heating seat 55 and the second heating seat 56 fixed thereon to rise and fall synchronously. Both the first heating seat 55 and the second heating seat 56 are equipped with electric heating tubes. By energizing the electric heating tubes, they are heated, and then the first heating seat 55 or the second heating seat 56 heats the steel back 13 or the lining 14, thereby facilitating the pressure bonding of the lining 14 and the steel back 13.

[0103] Example 5

[0104] Based on Examples 1-2, the upper pressing mechanism 6, the lower pressing mechanism 12 and their operating principles are described below, and implementation methods for their operation in conjunction with the six-station indexing plate 2 and the three-station indexing plate 3 are provided.

[0105] Based on the above technical solutions for the six-position indexing plate 2 and the three-position indexing plate 3, in order to ensure that the upper pressing mechanism 6 and the lower pressing mechanism 12 work together to press the steel back 13 and the lining material 14 after being heated by the upper heating mechanism and the lower heating mechanism into a finished brake pad, the following technical solutions for the upper pressing mechanism 6 and the lower pressing mechanism 12 are provided.

[0106] The upper pressing mechanism 6 includes a third lifting module and a pressing pad 61. The third lifting module is fixedly installed on the first fixed plate 15, and the pressing pad 61 is fixedly installed on the movable part of the third lifting module.

[0107] As one implementation, the third lifting module has the same structure as the first lifting module and the second lifting module involved in embodiment 4. Based on this technology, the pressing pad 61 is fixedly installed on the lower surface of the corresponding mounting base 60, and the pressing pad 61 is nested with the first processing groove 21 and applies downward pressure to the steel back 13 therein.

[0108] The lower pressing mechanism 12 includes a fourth lifting module and a lifting column 62. The fourth lifting module is fixedly installed on the workbench 1 and arranged below the second turntable 25. The lifting column 62 includes two sets arranged side by side, and both sets of lifting columns 62 are fixedly installed on the movable parts of the fourth lifting module.

[0109] As one implementation of the lower pressing mechanism 12, the fourth lifting module includes a mounting pad 63, a third telescopic cylinder 64, a lifting top plate 65, a connecting plate 66, a fourth telescopic cylinder 67, and a mounting top plate 68. The mounting pad 63 is fixedly installed on the workbench 1. The third telescopic cylinder 64 is vertically arranged and its fixed end is fixedly connected to the mounting pad 63. The lifting top plate 65 is fixedly installed on the movable end of the third telescopic cylinder 64 and is driven to move up and down by the third telescopic cylinder 64. To ensure the operational stability of the lifting top plate 65, as described in Embodiment 4, the first lifting module and the second lifting top plate 68 are used. Similar to the lowering module, a guide rod is fixedly connected to the mounting plate 63, which is vertically arranged and slidably inserted into the lifting top plate 65. The connecting plate 66 is fixedly connected to the lower side of the lifting top plate 65 through the connecting rod. An installation opening is provided at the center of the lifting top plate 65. The fixed end of the fourth telescopic cylinder 67 is fixedly connected to the connecting plate 66, and the fourth telescopic cylinder 67 is vertically arranged through the installation opening. The mounting top plate 68 is horizontally fixed to the movable end of the fourth telescopic cylinder 67. Two sets of lifting columns 62 are fixedly installed on the mounting top plate 68 and abut against the lower surface of the two sets of sliding pads 30 at the lower pressing station.

[0110] When the lower pressing mechanism 12 drives the sliding pad 30 and the heated lining material on it to move upward, and combines the lining material with the steel backing 13 to form a molded brake pad, firstly, the fourth telescopic cylinder 67 is controlled to extend and drive the two sets of lifting columns 62 to extend into the second processing groove 29 to abut against the lower surface of the sliding pad 30. Then, the third telescopic cylinder 64 is controlled to drive the lifting top plate 65 and the components connected to the lifting top plate 65 to move upward synchronously. Then, the lifting columns 62 are controlled to move upward again to lift the sliding pad 30 and the lining material upward. With the upper pressing mechanism 6 applying a reverse force, the molded part and the steel backing 13 are pressed into a whole.

[0111] Example 6

[0112] Based on Examples 1-2, the heat dissipation mechanism 7, the optical detection mechanism 8 and their operating principles are described below, and an implementation method for their operation in conjunction with the six-position indexing plate 2 is provided.

[0113] Based on the above technical solution for the six-station indexing plate 2, in order to ensure high-speed heat dissipation of the molded product after pressing the steel back 13 and the lining part 14 into brake pads, the following technical solution for the heat dissipation mechanism 7 is provided.

[0114] The heat dissipation mechanism 7 includes a connecting frame plate 69, an upper air jet path 70, a lower air jet path 71, and an air supply pump 72. The connecting frame plate 69 is fixedly installed on the workbench 1. The upper air jet path 70 and the lower air jet path 71 are both fixedly installed on the connecting frame plate 69. The upper air jet path 70 and the lower air jet path 71 are respectively arranged on the upper and lower sides of the first turntable 16. The upper air jet path 70 has vertically downward air jets evenly distributed, and the lower air jet path 71 has vertically upward air jets evenly distributed. The air supply pump 72 is connected to the upper air jet path 70 and the lower air jet path 71 through an air supply pipe 73.

[0115] The connecting frame plate 69 includes a mounting longitudinal plate and an upper horizontal plate, a lower horizontal plate, and a base plate fixed to the mounting longitudinal plate. The base plate is fixedly connected to the worktable 1. The upper air jet path 70 is fixedly installed on the lower surface of the upper horizontal plate and arranged towards the first processing groove 21 at the corresponding position. The lower air jet path 71 is fixedly installed on the upper surface of the lower horizontal plate and arranged towards the first processing groove 21 at the corresponding position. The air supply pump 72 is fixedly installed on the base plate.

[0116] After the upper pressing mechanism 6 and the lower pressing mechanism 12 work together to form the brake pad, the brake pad is installed in the first processing groove 21 at the corresponding position. By controlling the six-position indexing plate 2 to rotate, it is rotated to the heat dissipation position. By controlling the air supply pump 72 to work, cold air is sprayed from the upper air jet path 70 and the lower air jet path 71 to the steel back 13 side and the lining part 14 side of the brake pad, respectively, so as to quickly cool the brake pad in the first processing groove 21 to the room temperature, which facilitates the clamping, transfer and output of the formed brake pad.

[0117] Based on the above technical solution for the six-position indexing plate 2, in order to ensure that the brake discs that have been pressed and cooled are subjected to optical inspection in order to determine whether the brake pads meet the specifications required for processing, the following technical solution for the optical inspection mechanism 8 is provided.

[0118] The optical inspection mechanism 8 includes a mounting plate 74, a second clamping assembly, a transverse inspector 75, and a longitudinal inspector 76. The mounting plate 74 is fixedly mounted on the first fixed plate 15. The second clamping assembly is mounted on the mounting plate 74 and arranged vertically downward toward the first processing groove 21. The transverse inspector 75 is fixedly mounted on the mounting plate 74 and arranged horizontally. The longitudinal inspector 76 is fixedly mounted on the worktable 1 and arranged vertically upward.

[0119] In one embodiment, the second clamping assembly has the same structure as the first clamping assembly involved in embodiment 3. The fixed end of the first telescopic cylinder 44 is fixedly installed on the mounting plate and arranged vertically downward. The brake pads in the corresponding first processing groove 21 are clamped by the joint action of the bonding plate 46, the lifting plate 47, and the electromagnet 49, and are driven by the first telescopic cylinder 44 to extend out of the first mounting groove.

[0120] Since the quality of the brake pads after molding is mainly determined by the thickness of the lining part 14 and whether it is missing, both the transverse detector 75 and the longitudinal detector 76 use CCD detectors and are equipped with external covers. The transverse detector 75 can detect the thickness of the lining part 14, and the longitudinal detector 76 monitors vertically upward from the corresponding first processing groove 21 to detect whether the lining part 14 is missing. After the inspection is completed, the brake pads are put back into the first processing groove 21 by the second clamping assembly so that they can be transported to the finished product unloading station by the six-station indexing plate 2 for unloading.

[0121] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0122] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
