Description

Technical Field

[0001] This utility model relates to the field of brake pad testing, and in particular to a device for testing the flatness of automotive brake pads. Background Technology

[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration.

[0003] During the production of automotive brake pads, it is necessary to test the flatness of the brake pad friction surface to prevent uneven areas from preventing effective contact with the brake disc and thus affecting the braking performance of the vehicle. Existing testing methods are divided into traditional contact measurement and modern automatic non-contact measurement. However, traditional contact measurement is inefficient and the results are easily affected by the operator's experience, so it is no longer used in batch testing processes.

[0004] Existing detection methods are mostly modern automatic non-contact measurement methods such as laser scanning and machine vision. This method involves conveying the brake pads to the bottom of the detection device through a conveyor, and then using detection instruments such as 3D laser scanners or industrial cameras to scan or photograph the brake pads to identify uneven areas on their surface.

[0005] However, when placing brake pads on the conveyor for transport, workers need to manually flip the brake pads with the detection side facing down so that the detection device can effectively identify the brake pads. This method undoubtedly increases the workload of the workers, and the workers are in contact with the working conveyor during the process of flipping the brake pads, which can easily cause injury to the workers due to the influence of the conveyor. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0007] Therefore, one objective of this utility model is to provide a vehicle brake pad flatness detection device. By setting a flipping mechanism on one side of the support frame, the brake pads are all placed with the detection surface facing upwards when they fall onto the transmission component after passing through the flipping mechanism, thereby reducing the workload of the staff and effectively eliminating the risks that may be caused by manual flipping.

[0008] To achieve the above objectives, the first aspect of this utility model provides an automotive brake pad flatness detection device, comprising: a detection structure and a flipping structure, wherein: the detection structure includes a support frame, a transmission component, and a detection mechanism, wherein the transmission component is disposed inside the support frame; the detection mechanism is disposed on the top of the support frame and directly above the transmission component; and the flipping structure is disposed on one side of the support frame.

[0010] Specifically, the transmission assembly includes a conveyor belt, a drive roller, a driven roller, and a first drive device, wherein the conveyor belt is rotatably disposed inside the two conveyor belt frames; the drive roller and the driven roller are respectively rotatably disposed on opposite surfaces of the two conveyor belt frames, and the drive roller and the driven roller are respectively located at both ends inside the conveyor belt; the first drive device is fixedly disposed on the side wall of one of the two conveyor belt frames by a mounting bracket, and the output end of the first drive device is connected to one end of the drive roller.

[0011] Specifically, the detection mechanism is fixedly installed on top of the two conveyor belt frames.

[0012] Specifically, the flipping structure includes: a support frame, a rotating disk, a fixed disk, and a second driving device. The support frame is fixedly installed at one end of the two conveyor belt frames, and an inlet and an outlet are respectively inclinedly arranged on the hollow outer wall inside the support frame. The rotating disk is rotatably installed inside the support frame, and multiple flipping grooves are equally spaced on the rotating disk. A bearing groove is respectively opened on one side of each of the multiple flipping grooves. The fixed disk is concentrically installed inside the support frame, and a discharge groove is inclinedly opened on the fixed disk. The inclined end of the discharge groove is connected to the outlet.

[0013] Compared with the prior art, the present invention has the following advantages: The automotive brake pad flatness detection device of the present invention drives the rotating disk to rotate through the second drive device, so that the brake pads entering through the feed port are discharged from the discharge port onto the transmission component with the detection surface facing upward, thereby reducing the workload of the workers and eliminating the risk of manual rotation of the brake pads.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following describes an embodiment of the automotive brake pad flatness detection device with reference to the accompanying drawings.

[0019] like Figures 1-4 As shown, the automobile brake pad flatness detection device of this utility model embodiment may include: detection structure 1 and flipping structure 2.

[0020] The detection structure 1 includes a support frame 11, a transmission component 12, and a detection mechanism 13.

[0021] It should be noted that the detection mechanism 13 described in this embodiment can be a non-contact measurement device such as a 3D laser scanner.

[0022] The transmission component 12 is located inside the support frame 11, and the detection mechanism 13 is located on top of the support frame 11 and directly above the transmission component 12.

[0023] The flipping structure 2 is located on one side of the support frame 11.

[0024] It should be noted that the detection mechanism 13 described in this embodiment is fixedly installed on the top of the two conveyor belt frames 111.

[0025] Specifically, when it is necessary to test the flatness of brake pads in batches, the staff will activate the transmission component 12, the testing mechanism 13 and the flipping structure 2 respectively.

[0026] At this time, the staff only needs to continuously put the brake pads that need to be tested into the flipping structure 2. Through the continuous operation of the flipping structure 2, the brake pads will eventually be flipped so that the test surface is facing up and placed on the transmission component 12. Finally, the brake pads are transmitted to the testing mechanism 13 for testing through the transmission component 12.

[0027] like Figure 2 As shown, the automobile brake pad flatness detection device of this utility model embodiment includes: a support frame 11 including two conveyor belt frames 111 and four support legs 112.

[0028] Two conveyor belt frames 111 are respectively arranged on both sides of the transmission component 12, and four support legs 112 are respectively mirrored in pairs at the bottom of the two conveyor belt frames 111.

[0029] The transmission assembly 12 includes a conveyor belt 121, a drive roller 122, a driven roller 123, and a first drive device 124.

[0030] The conveyor belt 121 is rotatably disposed inside the two conveyor belt frames 111. The driving roller 122 and the driven roller 123 are rotatably disposed on the opposite surfaces of the two conveyor belt frames 111, and the driving roller 122 and the driven roller 123 are respectively located at both ends inside the conveyor belt 121. The first drive device 124 is fixedly disposed on the side wall of one of the conveyor belt frames 111 by a mounting bracket, and the output end of the first drive device 124 is connected to one end of the driving roller 122.

[0031] It should be noted that the transmission component 12 described in this embodiment can be replaced by a chain conveyor belt or other devices capable of stable transmission.

[0032] It should be further noted that the first driving device 124 described in this embodiment can be an electric motor.

[0033] Specifically, the first drive device 124 is activated to drive the active roller 122 to rotate, thereby driving the conveyor belt 121 and the driven roller 123 to rotate respectively through the rotating active roller 122, so that when the brake pad is at the top of the conveyor belt 121, it will move together with the rotating conveyor belt 121.

[0034] like Figure 3 Figure 4 As shown, the automobile brake pad flatness detection device of this utility model embodiment may include: a flipping structure 2 including: a support frame 21, a rotating disk 22, a fixed disk 23, and a second driving device 24.

[0035] The support frame 21 is fixedly installed at one end of the two conveyor belt frames 111. The inner hollow outer wall of the support frame 21 is provided with an inlet 211 and an outlet 212 respectively. The rotating disk 22 is rotatably installed inside the support frame 21. The rotating disk 22 is provided with four equidistant turning grooves 221. Each of the four turning grooves 221 is provided with a bearing groove 2211 on one side. The fixed disk 23 is concentrically installed inside the support frame 21. The fixed disk 23 is provided with an inclined feeding groove 231. The inclined end of the feeding groove 231 is connected to the outlet 212.

[0036] It should be noted that the heights of the tilting groove 221 and the feeding groove 231 described in this embodiment are equal to the width of the brake pad, and the width of the tilting groove 221 is equal to the length of the brake pad.

[0037] Specifically, when the second drive device 24 is started, it will drive the rotating disk 22 to rotate clockwise, so that the brake pads entering through the feed port 211 will fall into the four tilting slots 221 one by one.

[0038] When the brake pad detection surface inside the flip groove 221 faces the bearing groove 2211, it will fall into the bearing groove 2211 as the rotating disk 22 rotates (e.g., Figure 4 As shown in the figure, when the brake pad inside the bearing groove 2211 moves to the discharge port 212 via the rotating disk 22, the brake pad will fall out of the bearing groove 2211 due to gravity and slide out through the discharge port 212, at which time the detection surface of the brake pad is facing upward.

[0039] When the brake pad detection surface inside the flipping groove 221 and the bearing groove 2211 are in the same direction, when the brake pad moves to the feeding groove 231 along with the rotating disk 22, the brake pad will slide along the feeding groove 231 into the discharge port 212 and slide out through the discharge port 212. At this time, the brake pad detection surface is facing upward.

[0040] In summary, the automotive brake pad flatness detection device of this utility model drives the rotating disk to rotate through the second drive device, so that the brake pads entering through the feed port are discharged from the discharge port onto the transmission component with the detection surface facing upwards, thereby reducing the workload of the workers and eliminating the potential risks of manual rotation of the brake pads.
