Description

Technical Field

[0001] This invention relates to the field of brake pad thickness measurement technology, specifically to a processing device for automotive brake pads. Background Technology

[0002] In the automotive brake pad manufacturing process, the uniformity of brake pad thickness after demolding is a core indicator that determines braking stability, fit accuracy, and service life, making it an indispensable key process. Currently, in small-batch production and on-site processing scenarios within the industry, the common method for inspection is to manually use calipers to measure point by point.

[0003] In standard operation, disc brake pads are manually measured at 3-5 points. The pad is positioned manually, and caliper readings are used to determine if the thickness meets the standard. This method has significant technical shortcomings: Firstly, the limited number of measurement points and reliance on manual placement make it easy to overlook thickness protrusions or deviations at edges and corners, resulting in insufficient representativeness of the measurement results. Furthermore, the lack of a unified benchmark for manual handling and placement makes it easy for hand shaking to cause deviations in caliper fit, directly affecting the accuracy of thickness measurement and failing to meet the requirements of high-precision processing. Secondly, if abnormal protrusions are found during the measurement process, they cannot be marked immediately. In the subsequent grinding process, they cannot be quickly targeted and processed, which will reduce the production efficiency of automotive brake pads.

[0004] Existing methods of manually measuring thickness with calipers suffer from low accuracy, poor efficiency, and vague positioning of thickness defects, making them unsuitable for the stringent requirements of thickness uniformity in brake pad manufacturing. Therefore, there is an urgent need for a processing device adapted to post-molding processing scenarios, capable of improving thickness measurement accuracy, increasing the number of measurement points, and achieving precise positioning of protrusion defects, thus overcoming the technical bottlenecks of existing manual measurement processes.

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.

[0017] Please see Figures 1-7 The present invention provides a processing device for automobile brake pads, comprising a support frame 1, a control box 7 at the upper end of the support frame 1, characterized in that: the support frame 1 is provided with a bearing component and a first driving component for driving it to move back and forth, a measuring component and a second driving component for driving it to move left and right are provided above the bearing component, and a first lifting component 19 for driving the measuring component to move up and down is provided below the support frame 1. The bearing assembly is equipped with a discharge assembly; The measuring assembly includes a top base 21, a control module 24, a laser rangefinder 25, an annular base 28, and a cylindrical scale stone 35. The control module 24 is installed on the upper end of the top base 21, and the laser rangefinder 25 is installed on the lower end of the top base 21. Its detection end is equipped with a detection probe 26. The lower end of the top seat 21 is fixedly provided with a ring frame 27, and the ring seat 28 is located in the inner circle of the ring frame 27 and is rotatably connected to it. The top seat 21 is provided with a third drive assembly that drives the ring seat 28 to rotate. The laser rangefinder 25 is located at the center of the inner ring of the ring seat 28. A horizontal plate 32 is fixedly installed in the inner ring of the ring seat 28. A vertical tube 33 is vertically installed at one end of the horizontal plate 32. A first cavity 42 is provided inside the vertical tube 33. A cylindrical graduated stone 35 is inserted into the first cavity 42. A cylindrical block 36 is provided at the upper end of the vertical tube 33, which is located inside the first cavity 42 and slides with the vertical tube 33. A bottom cap 34 is provided at the lower end of the vertical tube 33 to limit the position of the cylindrical block 36. The upper end of the vertical tube 33 is provided with a second cavity 38 that passes through the horizontal plate 32 and communicates with the first cavity 42. The first cavity 42 is provided with a compression spring 43 located at the upper end of the cylindrical block 36. The measuring component also includes a second lifting component 37, which is installed on the upper end of the horizontal plate 32. Its output end is provided with a pressure block 39 that penetrates the second cavity 38. A pressure sensor 40 is fixedly installed at the lower end of the pressure block 39. The detection end of the pressure sensor 40 is provided with a pressure plate 41 located below the pressure block 39.

[0018] Initial preparation: Before loading, the support platform 3 and the top seat 21 are in their preset initial positions to ensure that there is no interference between the components. The demolded brake pad is placed in the limiting groove 10 of the bearing component. The two limiting blocks 9 fit tightly against the contours of the brake pad on both sides to precisely limit the brake pad and keep it in a stable position on the bearing component, laying the benchmark for subsequent measurement work.

[0019] Precise displacement and positioning: Control signals are sent from the control chassis 7 to the first drive assembly and the second drive assembly to start the first motor 5 and the second motor 22. After the first motor 5 starts, it drives the first threaded rod 6 to rotate. Since the first threaded rod 6 is threadedly connected to the support platform 3, and the support platform 3 is tightly attached to the support plate 2 through the bottom groove 4, the support platform 3 is driven to slide smoothly back and forth on the support plate 2 along the first threaded rod 6. At the same time, after the second motor 22 starts, it drives the second threaded rod 23 to rotate. The top seat 21 is threadedly connected to the second threaded rod 23 and is limited by the two guide rods 18. Therefore, the top seat 21 slides smoothly left and right along the second threaded rod 23 on the guide rods 18.

[0020] By coordinating the forward and backward movement of the support platform 3 and the left and right movement of the top seat 21, the laser rangefinder 25 of the measuring component is driven to move and position multiple points on the surface of the brake pad in sequence, thereby achieving multi-point coverage measurement of the entire surface of the brake pad.

[0021] Thickness detection and defect judgment: The laser rangefinder 25 detects the distance between itself and various points on the surface of the brake pad in real time through the detection probe 26, and then calculates the thickness of the corresponding points of the brake pad. The detection data is transmitted to the control module 24 in real time, and then fed back to the control box 7 by the control module 24. The display screen on the control box 7 displays the measurement results synchronously, intuitively showing whether the brake pad thickness meets the standard.

[0022] During the measurement process, the control module 24 continuously compares the test data with the rated range of brake pad thickness to determine whether there are protrusions or depressions at the corresponding points of the brake pad.

[0023] Precise defect marking: When a bulge or depression is detected at a certain point and the value exceeds the rated range of brake pad thickness, the control box 7 immediately activates the first lifting component 19.

[0024] The first lifting assembly 19 drives the bottom rod 20 to rise and fall via the drive rod. The vertical rods 16 at both ends of the bottom rod 20 slide and engage with the support frame 1, thereby driving the two L-shaped positioning frames 17 to descend synchronously. The L-shaped positioning frames 17 drive the top seat 21 and the entire measuring assembly to descend together, so that the vertical tube 33 drives the cylindrical scale stone 35 to descend synchronously.

[0025] The top seat 21 is lowered to the designated position. When the vertical tube 33 is lowered to the designated position, the lower end of the cylindrical scale stone 35 contacts the defect point surface of the brake pad. During the descent of the vertical tube 33, the cylindrical block 36 slides upward in the first cavity 42 and compresses the compression spring 43. The compression spring 43 always applies a downward elastic force to the cylindrical block 36 to ensure that the lower end of the cylindrical scale stone 35 can fit tightly against the surface of the brake pad. During this process, the pressure plate 41 will not contact the cylindrical block 36.

[0026] Subsequently, the control box 7 activates the second lifting assembly 37. The output end of the second lifting assembly 37 drives the pressure block 39 to move downward. After the pressure block 39 passes through the second cavity 38, the pressure sensor 40 at its lower end drives the pressure plate 41 to press down on the cylindrical block 36. The pressure sensor 40 detects the pressing pressure in real time and feeds it back to the control box 7. The control box 7 adjusts the output pressure of the second lifting assembly 37 according to the protrusion height or depression depth of the defect, so that the pressure at the cylindrical block 36 is kept within the specified range during the subsequent rotation of the cylindrical scale stone 35.

[0027] Simultaneously, the control unit 7 starts the third motor 30, which causes the drive shaft to rotate, driving the gear 31 to rotate synchronously. The gear 31 meshes with the gear ring 29 on the outer ring of the ring seat 28, thereby driving the ring seat 28 to rotate around the central axis of the laser rangefinder 25 within the ring frame 27. The ring seat 28 drives the horizontal plate 32, the vertical tube 33, and the cylindrical graduated stone 35 to rotate together. The cylindrical graduated stone 35 marks the defect points of the brake pads with circular marks. The severity of the defects is distinguished by the depth of the marks, which facilitates subsequent precise processing.

[0028] The bottom cap 34 is fastened to the lower end of the vertical tube 33 and is threaded into the vertical tube 33, which serves to limit the position of the cylindrical block 36. At the same time, the cylindrical graduated stone 35 passes through the bottom cap 34 and the two slide together to ensure the stability of the cylindrical graduated stone 35 during the rotation marking process.

[0029] Reset and unloading: After the defect marking is completed, the control box 7 controls the second lifting component 37, the third motor 30 and the first lifting component 19 to reset in sequence. At this time, the top seat 21 rises and resets, and subsequent measurements are carried out. After the top seat 21 rises, the compression spring 43 gradually extends, and the cylindrical block 36 will contact the bottom cap 34.

[0030] After all the preset points on the brake pads have been measured, the control box 7 starts the fourth motor 15. The fourth motor 15 drives the rotating shaft 13 to rotate, which in turn drives the cam block 14 to rotate in the second slot 12. During the rotation, the cam block 14 pushes upward, passes through the second slot 12 and the first slot 11, and then pushes up the brake pad in the limiting slot 10, so that the brake pad is separated from the base plate 8. This prevents the lower surface of the brake pad from sticking to the base plate 8, making it easier to pick up and put down the brake pads for the workers to proceed to the subsequent processing steps.

[0031] Component maintenance: When the cylindrical graduated stone 35 is severely worn or damaged, unscrew the bottom cap 34 that is threaded with the vertical tube 33, remove the old cylindrical graduated stone 35 and cylindrical block 36, replace the new cylindrical graduated stone 35, and then re-fasten and tighten the bottom cap 34 to complete the replacement of the cylindrical graduated stone 35. The operation is convenient and efficient.

[0032] This device effectively solves the technical bottlenecks of low accuracy, poor efficiency, and ambiguous defect location in the existing technology of manually measuring brake pad thickness with calipers through the coordinated cooperation of its various components. Combining the functional characteristics of all parts of the device, it brings the following significant benefits, and each part fully plays its role, ensuring the overall performance of the device is stable and practical.

[0033] Addressing the pain points of low efficiency and high labor intensity of manual point-by-point measurement, this system automates the entire thickness measurement process. Through the control chassis 7, all components work together to automatically complete brake pad thickness measurement and defect marking without manual intervention. It replaces the traditional manual caliper measurement method, avoiding errors from manual readings and fatigue, significantly improving thickness inspection efficiency, and is suitable for small-batch production and on-site processing scenarios, while reducing labor costs.

[0034] To address the drawback of poor adaptability of manual inspection, the device can adapt to the thickness measurement requirements of brake pads of different specifications after demolding by replacing the base plate 8 (different base plates 8 have different specifications of limiting grooves 10, and regardless of the specification of the limiting groove 10, the positions of the first empty groove 11 and the second empty groove 12 are all at the bottom of the limiting groove 10). At the same time, the detection parameters can be adjusted by controlling the control box 7 to adapt to the processing of brake pads of different thickness standards. It has a wide range of applications and strong practicality.

[0035] To address the pain point of large fluctuations in accuracy during manual inspection, the structure of thickness detection components has been optimized. The laser rangefinder 25 ensures stable detection, and the cylindrical scale stone 35 fits tightly with related components, ensuring smooth rotation of the marker. All drive and support components operate smoothly, reducing wear. The pressure sensor 40 regulates the marker pressure in real time to prevent damage to detection components or affecting detection results, ensuring long-term stability of thickness detection and extending the device's service life.

[0036] Both the first threaded rod 6 and the second threaded rod 23 are stably supported by bearing seats and are precisely threaded with corresponding components.
