Description

Technical Field

[0001] This application relates to the field of brake pad manufacturing technology, and in particular to a brake pad surface polishing device. Background Technology

[0002] Brake pads are one of the most critical safety components in a car. They typically consist of a steel plate, an adhesive heat-insulating layer, and friction blocks. During the manufacturing process, because the friction blocks are primarily bonded to the steel plate using a mold casting method, irregular particles and even some steel fibers may protrude from the surface of the formed friction blocks. If these irregular particles and protruding steel fibers are not treated, they can prevent the brake pads from achieving full contact with the brake disc during use, leading to uneven braking force and posing a safety hazard during vehicle operation.

[0003] A Chinese patent with publication number CN114310496A discloses a polishing process for automotive brake pads. Specifically, it discloses a transmission track, an adsorption mechanism, and a belt sander. During transmission, the brake pads are adsorbed by the adsorption mechanism and carried to the belt sander for polishing, thereby cleaning the burrs on the surface of the brake pads.

[0004] Regarding the aforementioned technologies, the sides of brake pads may also have defects such as protrusions and burrs during the molding process, which will affect the packaging, transportation, and installation of brake pads. Furthermore, the aforementioned polishing process is not suitable for polishing the sides of brake pads. Summary of the Invention

[0005] To facilitate the polishing of the sides of brake pads, this application provides a brake pad surface polishing device.

[0006] This application provides a brake pad surface polishing device, which adopts the following technical solution:

[0007] A brake pad surface polishing device includes a first belt sander, a conveyor belt, a fixing mechanism, and a rectangular polishing box. Multiple fixing mechanisms are provided on the conveyor belt for fixing the brake pads to be polished. The first belt sander is located on one side of the conveyor belt and contacts the surface of the brake pad. The polishing box is located behind the first belt sander in the conveying direction of the conveyor belt. The conveyor belt passes through the polishing box, and a polishing mechanism for polishing the sides of the brake pads is provided inside the polishing box.

[0008] By adopting the above technical solution, when polishing the formed brake pads, the brake pads are fixedly installed on the conveyor belt by a fixing mechanism. The conveyor belt drives the brake pads to pass through the first belt sander and the polishing box in sequence. The first belt sander grinds and polishes the surface of the brake pads. After the brake pads enter the polishing box, the polishing mechanism polishes the sides of the brake pads. Thus, while polishing the surface of the brake pads, it is also convenient to polish the sides of the brake pads.

[0009] Optionally, the fixing mechanism includes a base fixedly mounted on the conveyor belt and multiple suction cups vertically mounted on the base.

[0010] By adopting the above technical solution, the base is fixedly installed on the conveyor belt, and multiple suction cups are fixedly installed on the base. The brake pads are placed on the multiple suction cups, and the suction cups are activated to adsorb and fix the brake pads on the suction cups, thereby achieving the effect of fixing the brake pads on the conveyor belt.

[0011] Optionally, the polishing mechanism includes a second belt sander and a lifting component. The second belt sander is disposed inside the polishing box and above the conveyor belt. The lifting component is disposed inside the polishing box and connected to the second belt sander. The lifting component is used to drive the second belt sander to move in the vertical direction. A flip plate is provided on the base, and a suction cup is disposed on the flip plate. One side of the flip plate extends outside the base. The flip plate is hinged to the edge of the base located below the flip plate. A driving component for driving the flip plate to rotate is also provided on the base.

[0012] By adopting the above technical solution, when the base moves on the conveyor belt into the polishing box, the drive unit drives the flip plate to rotate. The flip plate rotates until it is in contact with the side wall of the base. At this time, the flip plate and the suction cup on the flip plate are rotated 90°. The brake pad on the suction cup is also rotated to be perpendicular to the ground. At this time, the upper surface of the brake pad is one side of the brake pad. The lifting unit drives the second belt sander to approach the brake pad. The second belt sander polishes the side of the brake pad located at the top. By changing the installation position of the brake pad on the base, different sides of the brake pad can be polished, thereby achieving the effect of facilitating the polishing of the side of the brake pad.

[0013] Optionally, the driving component includes a cylinder, the base is hollow, the cylinder body is hinged to the inner wall of the base, and the piston rod of the cylinder extends toward the flap and is hinged to the lower surface of the flap.

[0014] By adopting the above technical solution, the cylinder is activated, and the piston rod of the cylinder retracts. At this time, the cylinder drives the flap to move. When the piston rod of the cylinder is fully retracted into the base, the flap moves to the side of the base and then rotates 90°. When the piston rod of the driving cylinder extends, the flap flips upward until it touches the upper surface of the base, thereby achieving the effect of facilitating the flipping of the flap.

[0015] Optionally, the lifting component includes a mounting base and a hydraulic cylinder. Multiple guide rods are vertically arranged inside the polishing box. A mounting base is provided outside the second belt sander. The mounting base slides through the multiple guide rods. Multiple hydraulic cylinders are provided inside the polishing box. The piston rod of the hydraulic cylinder extends vertically upward and is connected to the mounting base.

[0016] By adopting the above technical solution, multiple hydraulic cylinders are started simultaneously. The piston rods of the hydraulic cylinders extend or retract, driving the mounting base to move vertically along the guide rod, thereby facilitating the movement of the second belt sander in the vertical direction.

[0017] Optionally, the flip plate is also provided with a turntable and a rotating component for driving the turntable to rotate, and a plurality of suction cups are provided on the turntable.

[0018] By adopting the above technical solution, when the brake pad rotates to be perpendicular to the ground, the rotating component drives the turntable to rotate, which in turn drives the brake pad mounted on the turntable to rotate, thereby rotating multiple sides of the brake pad to the top in sequence, so that the second belt sander can grind and polish the multiple sides of the brake pad.

[0019] Optionally, the rotating component includes a rotating shaft, a drive motor, a grooved wheel, and a dial. The dial is rotatably mounted on the flip plate via the rotating shaft. The grooved wheel is coaxially mounted on the rotating shaft. The drive motor is mounted on the flip plate and located on one side of the rotating shaft. The dial is coaxially fixed on the output shaft of the drive motor. The dial is provided with a lever. The edge of the grooved wheel has four arc-shaped grooves that fit with the edge of the dial. The grooved wheel has a locking groove between two adjacent arc-shaped grooves for locking the lever.

[0020] By adopting the above technical solution, the drive motor drives the dial to rotate. When the dial rotates until the lever is engaged in the engagement slot, the dial rotates and drives the grooved wheel to rotate. When the dial rotates until the lever disengages from the engagement slot, the dial rotates while the grooved wheel remains stationary. The grooved wheel has four arc-shaped grooves and four engagement slots, so that for every one rotation of the dial, the grooved wheel rotates a quarter rotation, thereby rotating the four sides of the brake pad to the top in sequence, which facilitates the grinding and polishing of the four sides of the brake pad.

[0021] Optionally, the inner wall of the hopper is covered with a polytetrafluoroethylene layer.

[0022] By adopting the above technical solution, the friction coefficient of polytetrafluoroethylene is improved, which facilitates the dust generated during the polishing process to slide down the collection hopper into the collection box, thus achieving the effect of easy dust collection.

[0023] Optionally, a material collection hopper is provided below both the first belt sander and the polishing box, and a collection box is connected below the material collection hopper. A filter screen is laid inside the collection box, and an air pump is connected to the top of the collection box.

[0024] By adopting the above technical solution, the first belt sander and the second belt sander grind and polish the brake pads. The dust and debris generated during the grinding of the brake pads fall into the collection hopper and enter the collection box along the collection hopper. The air pump draws air from the collection box, thereby drawing the dust into the collection box. The dust is blocked by the filter screen and collected in the collection box, thus preventing the dust from spreading and affecting the environment.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When polishing the formed brake pads, the brake pads are fixedly installed on the conveyor belt by a fixing mechanism. The conveyor belt drives the brake pads to pass through the first belt sander and the polishing box in sequence. The first belt sander grinds and polishes the surface of the brake pads. After the brake pads enter the polishing box, the polishing mechanism polishes the sides of the brake pads. Thus, while polishing the surface of the brake pads, it is also convenient to polish the sides of the brake pads.

[0027] 2. When the base moves on the conveyor belt into the polishing box, the drive unit drives the flap to rotate. The flap rotates until it is in contact with the side wall of the base. At this time, the flap and the suction cup on the flap rotate 90°, so that the brake pad on the suction cup also rotates to be perpendicular to the ground. At this time, the upper surface of the brake pad is one side of the brake pad. The lifting unit drives the second belt sander to approach the brake pad. The second belt sander grinds and polishes the side of the brake pad located at the top. By changing the installation position of the brake pad on the base, different sides of the brake pad can be ground and polished, thereby achieving the effect of facilitating the grinding and polishing of the side of the brake pad.

[0028] 3. When the brake pad rotates to be perpendicular to the ground, the rotating component drives the turntable to rotate, which in turn drives the brake pad mounted on the turntable to rotate, thereby rotating multiple sides of the brake pad to the top in sequence, so that the second belt sander can grind and polish the multiple sides of the brake pad.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a brake pad surface polishing device, referring to... Figure 1 and Figure 2 A brake pad surface polishing device includes an annular conveyor belt 2. A first belt sander 1 is fixedly installed on one side of the conveyor belt 2 via a support frame. The length direction of the first belt sander 1 is consistent with the length direction of the conveyor belt 2 and is located directly above the conveyor belt 2. It also includes a fixing mechanism 3 and a rectangular polishing box 4. Multiple fixing mechanisms 3 are installed at equal intervals on the conveyor belt 2 to fix the brake pads to be polished. The lower sanding belt of the first belt sander 1 abuts against the upper surface of the brake pads mounted on the fixing mechanism 3. The polishing box 4 is installed on the conveyor belt 2 and is located behind the first belt sander 1 in the conveying direction of the conveyor belt 2; that is, the fixing mechanism 3 with the brake pads installed passes through the first belt sander 1 before passing through the polishing box 4. Inlets and outlets are provided at both ends of the polishing box 4. The conveyor belt 2 passes through the inlets and outlets through the polishing box 4. A polishing mechanism for polishing the sides of the brake pads is installed inside the polishing box 4.

[0038] When polishing brake pads, the operator first installs the brake pads sequentially on the fixing mechanism 3, ensuring that the multiple brake pads are aligned. The conveyor belt 2 drives the fixing mechanism 3 sequentially through the first belt sander 1 and the polishing box 4. When the fixing mechanism 3 and the brake pads on it pass through the first belt sander 1, the first belt sander 1 grinds and polishes the surface of the brake pads; when the fixing mechanism 3 and the brake pads on it pass through the polishing box 4, the polishing mechanism polishes the sides of the brake pads; thus, not only the surface of the brake pads is polished, but also multiple sides of the brake pads are polished.

[0039] Reference Figure 3 and Figure 4 The fixing mechanism 3 includes a base 31 fixedly installed on the conveyor belt 2, and multiple suction cups 32 vertically installed on the top of the base 31. When fixing the brake pads, the brake pads are placed on the multiple suction cups 32, and the suction cups 32 are activated to adsorb and fix the brake pads.

[0040] Reference Figures 3-5 The polishing mechanism includes a second belt sander 51 and a lifting component 52. The second belt sander 51 is installed inside the polishing box 4, with its length along the length of the conveyor belt 2 and located directly above the conveyor belt 2. The lifting component 52 is installed inside the polishing box 4 and connected to the second belt sander 51. The lifting component 52 drives the second belt sander 51 to move vertically, allowing it to move closer to or away from the conveyor belt 2. The base 31 is a rectangular block, on which a flap 33 is installed. A suction cup 32 is installed on the top of the flap 33. The flap 33 extends beyond the base 31 to the side facing inwards from the conveyor belt 2. A hinge is installed on the edge of the base 31 below the flap 33, and the base 31 and the flap 33 are rotatably connected by the hinge. When the flap 33 is rotated to a horizontal position, it fits against the upper surface of the base 31. When the base 31 is rotated to a vertical position, it fits against the side wall of the base 31 facing inwards from the inner ring of the conveyor belt 2. The base 31 is also equipped with a drive component 6 for driving the flap 33 to rotate.

[0041] When the flap 33 is outside the polishing box 4, it is in a horizontal state. When the base 31 and the brake pads on it move into the polishing box 4, the drive unit 6 drives the flap 33 to rotate to a vertical state. At this time, the brake pads mounted on the flap 33 via the suction cup 32 also flip to a vertical state, and the top surface of the brake pads is one side. The lifting unit 52 drives the second belt sander 51 to move to fit against the top side of the brake pads and polish the side of the brake pads. By changing the installation position of the brake pads on the base 31, the multiple sides of the brake pads can be positioned sequentially at the top, thereby polishing the multiple sides of the brake pads.

[0042] Reference Figure 3The driving component 6 includes a cylinder 61, a hollow base 31 with an opening facing the inner ring of the conveyor belt 2, a multi-stage cylinder, the end of the cylinder body of the cylinder 61 being hinged to the inner wall of the base 31 on the outer ring side of the conveyor belt 2, the piston rod of the cylinder 61 extending obliquely toward the flap 33 through the opening of the base 31, and the end of the piston rod of the cylinder 61 being hinged to the lower surface of the flap 33.

[0043] When cylinder 61 is activated, its piston rod extends or retracts. When the piston rod extends, cylinder 61 drives the flap 33 to rotate until it is in contact with the upper surface of the base 31. At this time, the flap 33 is in a horizontal state, and the brake pads on the flap 33 are also in a horizontal state, which facilitates the first belt sander 1 to polish the surface of the brake pads. When the piston rod retracts, cylinder 61 drives the flap 33 to rotate until it is in contact with the side of the base 31. At this time, the flap 33 is in a vertical state, and the brake pads on the flap 33 are also in a vertical state, thereby flipping the side of the brake pads to the top, which facilitates the second belt sander 51 to grind and polish the side of the brake pads.

[0044] Reference Figure 3 and Figure 4 The flip plate 33 is also horizontally mounted with a turntable 331 and a rotating component 7 for driving the turntable 331 to rotate. Multiple suction cups 32 are mounted on the upper surface of the turntable 331. When the flip plate 33 is flipped to the vertical position, the rotating component 7 drives the turntable 331 to rotate, thereby rotating multiple sides of the brake pad to the top in sequence, and then polishing them by the second belt sander 51.

[0045] Reference Figure 4 The rotating component 7 includes a rotating shaft 71, a drive motor 72, a grooved wheel 73, and a dial 74. The rotating shaft 71 is vertically rotatably mounted in the center of the flap 33, and the turntable 331 is horizontally fixedly mounted on its top. The turntable 331 is rotatably mounted on the flap 33 via the rotating shaft 71. The grooved wheel 73 is coaxially fixedly mounted in the middle of the rotating shaft 71. The drive motor 72 is fixedly mounted on the flap 33 and located on one side of the rotating shaft 71, with its output shaft extending vertically upwards. The dial 74 is coaxially fixedly mounted on the output shaft of the drive motor 72. The dial 74 is circular and is located on the same horizontal plane as the grooved wheel 73. Four arc-shaped grooves 731, which fit against the edges of the dial 74, are equally spaced along the edge of the grooved wheel 73. A locking groove 732 is formed on the grooved wheel 73 between adjacent arc-shaped grooves 731, extending along the diameter of the grooved wheel 73. A connecting rod is fixedly installed at the bottom of the dial 74. The connecting rod coincides with one of the radii of the dial 74. A vertically extending lever 741 is installed at the end of the connecting rod. The lever 741 is adapted to the locking groove 732. An arc-shaped groove is opened on the dial 74 at the location of the connecting rod.

[0046] The drive motor 72 is started, driving the dial 74 to rotate. When the edge of the dial 74 engages with the arc-shaped groove 731 of the grooved wheel 73, the dial 74 rotates while the grooved wheel 73 remains stationary. When the dial 74 rotates until the lever 741 is in the locking groove 732, the dial 74 rotates, driving the grooved wheel 73 to rotate. When the grooved wheel 73 has rotated a quarter turn, the lever 741 disengages from the locking groove 732. At this point, the dial 74 continues to rotate, while the grooved wheel 73 remains stationary. After the dial 74 has rotated one full turn, the lever 741 engages with the locking groove 732 again, driving the grooved wheel 73 to rotate a quarter turn. This drives the turntable 331 to rotate intermittently, rotating a quarter turn each time, thereby sequentially rotating the four sides of the brake pad on the turntable 331 to the top, achieving sequential polishing and grinding of the four sides of the brake pad.

[0047] Reference Figure 5 The lifting component 52 includes a mounting base 521 and hydraulic cylinders 522. Cylindrical guide rods 523 are vertically installed at the four corners inside the polishing box 4. The mounting base 521, a rectangular frame, is installed outside the second belt sander 51. Through holes are provided at each of the four corners of the mounting base 521, and the mounting base 521 slides along the four guide rods 523. Multiple hydraulic cylinders 522 are installed inside the polishing box 4. The piston rods of all hydraulic cylinders 522 extend vertically upwards, and the ends of the piston rods of all hydraulic cylinders 522 are connected to the mounting base 521.

[0048] The flip plate 33 and the brake pads on it are flipped to a vertical position inside the polishing box 4. At this time, the multiple sides of the brake pads are driven to rotate sequentially to the top by the rotating component 7. When the brake pads rotate to different positions, the height of the top surface of the brake pads is inconsistent. At this time, the hydraulic cylinder 522 needs to be activated. By extending or retracting the piston rod of the hydraulic cylinder 522, the height of the second belt sander 51 is adjusted so that the brake pads can rotate normally, and the second belt sander 51 is adjusted to be in contact with the top surface of the brake pads to achieve polishing of the sides of the brake pads.

[0049] Reference Figure 2 and Figure 5 Below both the first belt sander 1 and the polishing box 4, there are material collection hoppers 8, with their openings facing downwards. A collection box 81 is installed at the bottom of the material collection hopper 8, and a feed inlet is located at the top of the collection box 81. The material collection hopper 8 is connected to the collection box 81 through the feed inlet. The inner wall of the material collection hopper 8 is covered with a polytetrafluoroethylene (PTFE) layer. PTFE has an extremely low coefficient of friction, so the dust generated during brake pad polishing experiences very little friction when it falls onto the material collection hopper 8, making it easy for the dust to slide down the material collection hopper 8 into the collection box 81. A filter screen 82 is installed inside the collection box 81 to block the dust generated during polishing. Figure 1An air pump 83 is installed between the two collection boxes 81 via an air supply pipe. Both collection boxes 81 are connected to the input end of the air pump 83, and the output end of the air pump 83 is connected to the external environment. When the air pump 83 is started, it sucks up the dust on the collection hopper 8, further improving the efficiency of dust falling into the collection hopper 8. At the same time, the dust is blocked by the filter screen 82 in the collection box 81, and the dust is stored and collected in the collection box 81.

[0050] Reference Figure 5 A blower 9 is installed on the top of the polishing box 4. The input end of the blower 9 is connected to the external environment, and the output end of the blower 9 is connected to an air supply pipe. The air supply pipe extends into the polishing box 4 and towards the base 31. An air jet nozzle 91 is installed at the end of the air supply pipe. When the blower 9 is started, it sprays air through the air jet nozzle 91 towards the base 31, blowing off the dust adhering to the base 31 and brake pads. The blown-off dust falls into the collection hopper 8 below, facilitating the cleaning of dust on the base 31 and brake pads. When the first belt sander 1 and the second belt sander 51 are working, some dust will also fall onto the conveyor belt 2, and the air jet nozzle 91 can also clean the dust on the conveyor belt 2.

[0051] It should be noted that multiple bases 31 can exist simultaneously beneath the first belt sander 1 and the second belt sander 51, allowing multiple brake pads to be polished simultaneously using both machines. When multiple brake pads are present in the polishing box 4, their positions change synchronously to ensure that the second belt sander 51 can polish the sides of multiple brake pads simultaneously. Meanwhile, the conveyor belt 2 operates intermittently. When the base 31 and the brake pads on it move into the polishing box 4, the conveyor belt 2 stops. After the brake pads have rotated sequentially and all four sides have been polished, the conveyor belt 2 resumes operation, transporting the next batch of brake pads to the polishing box 4 for polishing.

[0052] The implementation principle of the brake pad surface polishing equipment in Embodiment 1 of this application is as follows: brake pads are placed sequentially and aligned on the base 31. The brake pads are fixed on the base 31 by suction cups 32. The conveyor belt 2 drives the base 31 to pass sequentially through the first sander 1 and the polishing box 4. The first sander 1 polishes the upper surface of the brake pads. The brake pads are flipped in the polishing box 4 to be perpendicular to the ground. The top side of the brake pads is polished by the second sander 51. The rotating part 7 drives the brake pads to rotate multiple sides sequentially to the top, thereby polishing multiple sides of the brake pads.

[0053] Finally, it should be noted that in the description of this application, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
