Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a quality testing device for brake pads of new energy vehicles. Background Technology
[0002] Brake pads, also known as brake linings, are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads; therefore, good brake pads are considered the guardian angels of both people and vehicles. Brake pads generally consist of a steel plate, an adhesive heat-insulating layer, and friction blocks. During the manufacturing process, brake pads require testing equipment to inspect their thickness and for internal cracks.
[0003] Existing testing equipment typically uses a conveyor mechanism to transport brake pads to the bottom of the testing device for evaluation. However, because there are no limiting positions during transport, the brake pads are prone to displacement during testing, resulting in poor performance. Furthermore, after testing, workers need to manually separate the qualified and unqualified brake pads, which is cumbersome and also leads to poor performance. Therefore, we propose a new quality testing device for brake pads in new energy vehicles. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a quality assessment device for brake pads in new energy vehicles.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quality inspection device for brake pads of new energy vehicles is designed, including a base, two first strip-shaped mounting plates are symmetrically installed on the top of the base, and a conveying mechanism is provided between the two first strip-shaped mounting plates; The top of the base is equipped with a U-shaped frame with the opening facing downwards. Fixing plates are symmetrically installed on both sides of the top of the U-shaped frame. A laser rangefinder is connected to the bottom of one fixing plate via a bracket, and a flaw detection probe is connected to the bottom of the other fixing plate via a bracket. Inside the U-shaped frame, there is a movable plate. The top of the movable plate is connected to the U-shaped frame through a first telescopic mechanism. At least one second connecting rod is rotatably connected to both sides of the bottom of the movable plate. Inside the U-shaped frame, there are also two symmetrically arranged limiting baffles. The top of each limiting baffle is equipped with a second strip mounting plate. The top of each second strip mounting plate is rotatably connected to the corresponding second connecting rod. Several support legs are installed on the bottom edge of the base. A shelf is provided at one end of the bottom of the base. One end of the shelf is fixed to the side of the support leg, and two collection boxes with upward openings are installed on the top of the shelf. The top of the base has an opening slot, and a strip connecting block is installed inside the opening slot. A first guide plate is installed at one end of the strip connecting block. The first guide plate is inclined and one end of the first guide plate extends below the conveying mechanism, while the other end of the first guide plate extends above one of the collection boxes. A second guide plate is slidably connected to the bottom of the first guide plate. A second support plate is installed at one bottom end of the second guide plate. A second telescopic mechanism is installed on one side of the second support plate. The other end of the second telescopic mechanism is fixed to the bottom of the strip connecting block through the first support plate. When the second telescopic mechanism extends, the end of the second guide plate away from the first guide plate extends to the top of another collection box.
[0006] Preferably, the conveying mechanism includes a plurality of support rollers disposed between two first strip mounting plates, with both ends of each support roller rotatably connected to the side of the first strip mounting plate, and the support rollers are connected to each other by a conveyor belt. The support roller at one end is connected to a drive motor, which is fixed to the first strip mounting plate.
[0007] Preferably, one end of each of the two limiting baffles is inclined outward, forming a funnel-shaped opening between the ends.
[0008] Preferably, through slots are provided on both sides of the top of the U-shaped frame, and a guide rod is installed inside each through slot. A first connecting rod is vertically installed on the top of each limiting baffle, and the top of each first connecting rod extends into the corresponding through slot and slides onto the corresponding guide rod.
[0009] Preferably, strip baffles are installed on both sides of the top of the first guide plate, and strip limiting plates are installed on both sides of the top of the second guide plate, with the top of each strip limiting plate extending to the side of the strip baffle located on the same side.
[0010] Preferably, strip guide plates are installed on the adjacent surfaces of the two strip limit plates, and each strip baffle has a limit groove on the side near the strip limit plate. One side of each strip guide plate extends into the corresponding limit groove and is slidably connected to the limit groove.
[0011] Preferably, a control cabinet is installed on the bottom edge of the base. The controller inside the control cabinet is connected to the first telescopic mechanism, the second telescopic mechanism and the drive motor respectively through wires. The controller is also connected to the laser rangefinder and the flaw detection probe respectively through wires.
[0012] The design scheme proposed in this utility model has the following beneficial effects in application: 1. The first telescopic mechanism can drive the moving plate to rise and fall, and then, under the action of the first and second connecting rods, it can drive the two limit baffles to move synchronously relative to each other. The limit baffles can limit the brake pads, prevent the brake pads from shifting position during transportation, and improve the performance.
[0013] 2. The second telescopic mechanism can drive the second guide plate to move along the first guide plate. When the brake pads are qualified, one end of the second guide plate extends out of the first guide plate. When the brake pads are unqualified, the second guide plate moves completely under the first guide plate. This allows the inspected brake pads to be classified and the qualified and unqualified brake pads to be guided into different collection boxes, thus improving the efficiency of use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figures 1-6A quality inspection device for brake pads of new energy vehicles includes a base 1, a control cabinet 29 installed on the bottom edge of the base 1, and a controller inside the control cabinet 29. The controller is one of a control motherboard, a host, or a PLC logic controller.
[0018] like Figure 1 and Figure 5 As shown, two first strip mounting plates 2 are symmetrically installed on the top of the base 1. A conveying mechanism is provided between the two first strip mounting plates 2. The specific structure of the conveying mechanism is as follows: the conveying mechanism includes several support rollers 16 arranged between the two first strip mounting plates 2. Both ends of each support roller 16 are rotatably connected to the side of the first strip mounting plate 2, and the support rollers 16 are connected to each other by a conveyor belt 3. The end of one support roller 16 is connected to a drive motor 30, which is fixed on the first strip mounting plate 2. The drive motor 30 is connected to a controller through a wire. In actual use, the operator places the brake pads on the conveyor belt 3, and then the drive motor 30 can drive the conveyor belt 3 to move under the action of the support rollers 16 to convey the brake pads.
[0019] like Figure 2 and Figure 5 As shown, a U-shaped frame 9 with an opening facing downwards is installed on the top. Fixing plates 12 are symmetrically installed on both sides of the top of the U-shaped frame 9. A laser rangefinder 5 is connected to the bottom of one fixing plate 12 via a bracket, and a flaw detector 13 is connected to the bottom of the other fixing plate 12 via a bracket. Both the laser rangefinder 5 and the flaw detector 13 are connected to the controller via wires. In actual use, when the conveyor belt 3 transports the brake pads to below the laser rangefinder 5, the laser emitted by the laser rangefinder 5 detects the thickness of the brake pads and transmits the detected data to the controller for processing. Then, when the brake pads are transported to below the flaw detector 13, the X-rays emitted by the flaw detector 13 can detect internal cracks in the brake pads and transmit the detected data to the controller for processing.
[0020] like Figure 2 and Figure 4As shown, a movable plate 14 is provided inside the U-shaped frame 9. The top of the movable plate 14 is connected to the U-shaped frame 9 through a first telescopic mechanism 6. The first telescopic mechanism 6 is one of an electric push rod, a cylinder, or a hydraulic rod, and is connected to a controller through a wire. At least one second connecting rod 15 is rotatably connected to both sides of the bottom of the movable plate 14. Two limiting baffles 4 are also symmetrically provided inside the U-shaped frame 9. A second strip mounting plate 10 is installed on the top of each limiting baffle 4. The top of each second strip mounting plate 10 is rotatably connected to the corresponding second connecting rod 15. In actual use, the movable plate 14 can be raised and lowered by the extension and retraction of the first telescopic mechanism 6, which in turn controls the rotation of the second connecting rod 15. The second connecting rod 15 can synchronously drive the two limiting baffles 4 to move relative to each other, limiting the brake pads on the conveyor belt 3 and preventing the brake pads from shifting position and affecting the inspection.
[0021] like Figure 2 and Figure 4 As shown, through slots 7 are provided on both sides of the top of the U-shaped frame 9. A guide rod 8 is installed inside each through slot 7. A first connecting rod 11 is vertically installed on the top of each limiting baffle 4. The top of each first connecting rod 11 extends into the corresponding through slot 7 and slides onto the corresponding guide rod 8. In actual use, the limiting baffle 4 can be limited by the cooperation of the first connecting rod 11 and the guide rod 8, so as to prevent the limiting baffle 4 from rising and falling with the moving plate 14.
[0022] like Figure 1 and Figure 5 As shown, several support legs 24 are installed on the bottom edge of the base 1. A shelf 23 is provided at one end of the bottom of the base 1. One end of the shelf 23 is fixed to the side of the support leg 24. Two collection boxes 22 with upward openings are installed on the top of the shelf 23. In actual use, the brake pads after testing are all transported to the collection box 22 by the conveyor belt 3 for collection.
[0023] like Figure 1 and Figure 6As shown, the top end of the base 1 has an opening slot 17, inside which a strip connecting block 25 is installed. A first guide plate 18 is installed at one end of the strip connecting block 25. The first guide plate 18 is inclined, with one end extending below the conveying mechanism and the other end extending above one of the collection boxes 22. A second guide plate 19 is slidably connected to the bottom of the first guide plate 18. A second support plate 28 is installed at one bottom end of the second guide plate 19. A second telescopic mechanism 26 is installed on one side of the second support plate 28. The other end of the second telescopic mechanism 26 is fixed to the bottom of the strip connecting block 25 via the first support plate 27. The second telescopic mechanism 26 is one of an electric push rod, a cylinder, or a hydraulic rod. The second telescopic mechanism 26 is connected to a controller via a wire, and when the second telescopic mechanism... When the second guide plate 19 extends, the end of the second guide plate 19 away from the first guide plate 18 extends above the other collection box 22. In actual use, after receiving data from the laser rangefinder 5 and the flaw detection probe 13, the controller can control the second telescopic mechanism 26 to extend and retract. When a qualified brake pad falls from the conveyor belt 3 onto the first guide plate 18, the second telescopic mechanism 26 retracts, moving the second guide plate 19 to the bottom of the first guide plate 18. In this way, the qualified brake pad can fall into one of the collection boxes 22 through the first guide plate 18. When an unqualified brake pad falls from the conveyor belt 3 onto the first guide plate 18, the second telescopic mechanism 26 extends, moving the end of the second guide plate 19 above the other collection box 22. The unqualified brake pad can fall into the other collection box 22 through the second guide plate 19, completing the separation.
[0024] It should be noted that, as Figure 3 As shown, strip baffles 20 are installed on both sides of the top of the first guide plate 18, and strip limiting plates 21 are installed on both sides of the top of the second guide plate 19. The top of each strip limiting plate 21 extends to the side of the strip baffle 20 located on the same side. The strip baffles 20 can block the sides of the first guide plate 18 to prevent the brake pads from falling off the sides of the first guide plate 18 when moving along the first guide plate 18. The strip limiting plates 21 can also block the sides of the second guide plate 19 to prevent the brake pads from falling off the sides of the second guide plate 19.
[0025] like Figure 3 As shown, strip guide plates 31 are installed on the adjacent surfaces of the two strip limit plates 21. Each strip baffle 20 has a limit groove 32 on the side near the strip limit plate 21. One side of the strip guide plate 31 extends into the corresponding limit groove 32 and slides in connection with the limit groove 32. The second guide plate 19 can be limited by the cooperation of the limit groove 32 and the strip guide plate 31, so that the second guide plate 19 and the first guide plate 18 remain stable.
[0026] Specifically, in use, the operator places the brake pad to be tested on the conveyor belt 3, and then controls the drive motor 30 to work through the controller. The drive motor 30 drives the conveyor belt 3 to move through the support roller 16, conveying the brake pad towards the U-shaped frame 9. During the conveying process, the controller controls the first telescopic mechanism 6 to extend, which pushes the moving plate 14 to move in detail. Under the action of the second connecting rod 15, the moving plate 14 synchronously drives the two limiting baffles 4 to move horizontally relative to each other. When the distance between the two limiting baffles 4 reaches the preset distance, the first telescopic mechanism 6 stops extending, and the brake pad conveyed by the conveyor belt 3 can move along the two limiting baffles 4. When the brake pad moves below the laser rangefinder 5, the laser rangefinder 5 can detect the distance between the top of the brake pad and the top of the conveyor belt 3, thus measuring the thickness of the brake pad and transmitting the detection data to... In the controller, the brake pads continue to move along the conveyor belt 3. When the brake pads move below the flaw detection probe 13, the X-rays emitted by the flaw detection probe 13 detect the internal cracks of the brake pads and transmit the detection data to the controller. Then, the brake pads are conveyed to the first guide plate 18 by the conveyor belt 3. If the brake pads are qualified, the controller controls the second telescopic mechanism 26 to retract, moving the second guide plate 19 below the first guide plate 18. The brake pads fall into the collection box 22 below under the action of the first guide plate 18 for collection. If the brake pads falling on the first guide plate 18 are unqualified, the controller controls the second telescopic mechanism 26 to extend, pushing the second guide plate 19 out from the bottom of the first guide plate 18. The brake pads falling on the first guide plate 18 can fall along the first guide plate 18 and the second guide plate 19 into another collection box 22 for collection, completing the separation.
[0027] Furthermore, such as Figure 4 As shown, one end of each of the two limiting baffles 4 is tilted outward, forming a flared opening between the ends. This prevents the brake pads from being blocked by the ends of the limiting baffles 4, thus avoiding affecting the detection.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
