Description

Technical Field

[0001] This utility model relates to the field of brake disc testing technology, and in particular to a brake disc ventilation duct testing device. Background Technology

[0002] In automotive braking systems, the brake disc, as a core load-bearing component, directly determines the heat dissipation efficiency during braking through the structural integrity and unobstructed flow of its ventilation channels, thus affecting the stability and lifespan of the braking system. When the brake disc ventilation channels are blocked, deformed, cracked, or have dimensional deviations during manufacturing, heat cannot be dissipated in time during braking, leading to brake fade. In severe cases, this can cause brake failure, posing a significant threat to driving safety. Therefore, quality inspection of the ventilation channels is a crucial step in the brake disc manufacturing process, ensuring that every brake disc leaving the factory meets the design standards and usage requirements for its ventilation channels. Currently, the industry relies heavily on manual visual inspection or simple tooling for the inspection of brake disc ventilation channels. Manual visual inspection requires personnel to examine the internal condition of each ventilation channel, which is not only labor-intensive but also inefficient, making it unsuitable for the high-speed mass production demands of modern production lines. Furthermore, manual inspection is susceptible to subjective judgment and visual fatigue, compromising the consistency and accuracy of results and leading to missed or false positives. While some simple tooling-assisted inspection methods reduce reliance on manual labor to some extent, they often only inspect certain dimensions or surface conditions of the ventilation channels, failing to provide comprehensive image information for detailed analysis. Additionally, manual assistance in positioning and adjusting the brake disc is required during the inspection process, resulting in low automation and making it difficult to meet the needs of inspecting large volumes of brake disc ventilation channels. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a brake disc ventilation duct testing device that can automate the testing of brake disc ventilation ducts and meet the testing needs of large-volume brake disc ventilation ducts.

[0004] This utility model is achieved through the following technical solution: A brake disc ventilation duct detection device, comprising: A feeding conveyor line, which is used to transport the brake disc to be tested; The detection component includes a frame, a motor, a rotating platform, and an industrial camera. The rotating platform and the industrial camera are respectively mounted on the frame. The brake disc is placed on the rotating platform. The motor drives the rotating platform to rotate, thereby causing the brake disc to rotate synchronously. The industrial camera is used to collect image information of the ventilation duct of the brake disc. A feeding conveyor line, which is used to transport the brake disc after testing; A transport assembly for gripping the brake disc of the loading conveyor and delivering it to the rotating platform, and for gripping the brake disc of the rotating platform and delivering it to the unloading conveyor; A control system is electrically connected to the motor, industrial camera, and transport component, respectively.

[0005] Furthermore, the detection component also includes a single-axis motion module, which is electrically connected to the control system, and a mounting bracket is fixed on the sliding block of the single-axis motion module, and the industrial camera is fixed on the mounting bracket.

[0006] Furthermore, the detection component also includes an illumination source, which is fixed on the mounting bracket and located between the industrial camera and the rotating platform.

[0007] Furthermore, it also includes a supplementary light source. The center of the rotating platform has a through-hole first opening, and the center of the brake disc has a through-hole second opening. The supplementary light source passes through the first opening and the second opening to provide supplementary lighting for the ventilation duct.

[0008] Furthermore, it also includes a mounting base, which is fixed on the frame, and the supplementary light source is fixed on the mounting base.

[0009] Furthermore, a light-blocking plate is fixed on the frame, the light-blocking plate surrounds the outer periphery of the rotating platform, and a shooting port is opened on the side of the light-blocking plate near the industrial camera.

[0010] Furthermore, the transport component includes a three-axis motion module and a suction cup, the three-axis motion module being used to drive the suction cup to move, and the suction cup being used to grip the brake disc.

[0011] Furthermore, both the loading conveyor line and the unloading conveyor line are equipped with multiple rollers for transporting the brake disc.

[0012] Furthermore, baffles are respectively provided on the feeding conveyor line and the unloading conveyor line, and the baffles are used to limit the brake disc.

[0013] Furthermore, the feeding conveyor and the unloading conveyor are respectively inclined to the horizontal plane, so that the brake disc moves by itself from the feeding end of the feeding conveyor / the unloading conveyor to the unloading end of the feeding conveyor / the unloading conveyor under the action of gravity.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. Through the coordination of the feeding conveyor line, transportation components, inspection components, unloading conveyor line and control system, the brake disc is fully automated and continuously operated from conveying, grabbing and transferring, inspection to unloading, which greatly reduces manual intervention, avoids the uncertainty of manual operation, shortens the inspection time of a single disc, meets the inspection needs of large batches of brake discs, and improves the overall production efficiency.

[0015] 2. By moving the lighting source synchronously with the industrial camera, stable and uniform light is provided, eliminating shadows and reflections. Secondly, by using a supplementary light source to illuminate from the center of the brake disc outwards, the internal details of the ventilation duct are fully revealed, enhancing the defect identification capability. Furthermore, a light-blocking plate is set up to isolate external stray light, ensuring image contrast and clarity. The combination of these three factors significantly improves the image quality captured by the industrial camera, effectively reducing missed and false detections, and improving the accuracy of identifying ventilation duct blockages, cracks, and casting defects.

In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. 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.

[0019] like Figures 1-5As shown, an embodiment of the present invention provides a brake disc ventilation duct testing device, comprising a feeding conveyor line 100, a testing component 200, a discharging conveyor line 300, a transport component 400, and a control system. The feeding conveyor line 100 is used to transport the brake disc 1 to be tested. The testing component 200 includes a frame 210, a motor 220, a rotating platform 230, and an industrial camera 240. The rotating platform 230 and the industrial camera 240 are respectively mounted on the frame 210. The brake disc 1 is placed on the rotating platform 230. The motor 210... 20 is used to drive the rotating platform 230 to rotate, thereby driving the brake disc 1 to rotate synchronously. The industrial camera 240 is used to collect image information of the ventilation duct 10 of the brake disc 1. The unloading conveyor line 300 is used to transport the brake disc 1 after inspection. The transport component 400 is used to grab the brake disc 1 on the loading conveyor line 100 and send it to the rotating platform 230, and grab the brake disc 1 on the rotating platform 230 and send it to the unloading conveyor line 300. The control system is electrically connected to the motor 220, the industrial camera 240 and the transport component 400 respectively. During operation, the brake disc 1 to be inspected is first smoothly conveyed to the designated gripping position by the feeding conveyor line 100. The control system drives the transport component 400 to accurately grip the brake disc 1 on the feeding conveyor line 100 and place it smoothly on the rotating platform 230 of the inspection component 200. Then, the control system controls the motor 220 to start, and the motor 220 drives the rotating platform 230 to rotate at a constant speed. The brake disc 1 rotates synchronously with the rotating platform 230. At this time, the industrial camera 240 starts working under the coordination of the control system, continuously collecting all-round image information of the ventilation duct 10 of the brake disc 1. The image information can be displayed in real time. The data is transmitted to the control system for analysis and judgment. After the inspection is completed, the control system drives the transport component 400 again to grab the inspected brake disc 1 from the rotating platform 230 and send it to the unloading conveyor line 300. The unloading conveyor line 300 then transports it to the subsequent process. The whole process realizes the automated continuous operation of brake disc ventilation channel inspection, which not only greatly reduces manual intervention and avoids the subjective error of manual inspection, but also improves the inspection accuracy. Furthermore, the efficient collaboration of each component shortens the inspection time of a single disc, significantly improves the overall inspection efficiency, and meets the inspection needs of large batches of brake disc ventilation channels.

[0020] In this embodiment, since the brake disc 1 has a certain weight and the rotating platform 230 rotates at a relatively slow speed, there is no need to set up an additional fixing device to lock or limit the brake disc 1. The brake disc 1 can rotate stably and synchronously with the rotating platform 230 by its own weight. This simplifies the structure, reduces the manufacturing cost and maintenance difficulty of the equipment, and avoids the risk of deformation or damage to the brake disc 1 caused by uneven clamping force.

[0021] like Figure 3As shown, the detection component 200 also includes a single-axis motion module 250, which is electrically connected to the control system. A mounting bracket 252 is fixed on the sliding block 251 of the single-axis motion module 250, and the industrial camera 240 is fixed on the mounting bracket 252.

[0022] The detection assembly 200 also includes an illumination source 260, which is fixed on the mounting bracket 252 and located between the industrial camera 240 and the rotating platform 230. The illumination source 260 moves synchronously with the industrial camera 240, providing a stable and uniform lighting environment for the brake disc ventilation duct 10 during the detection process, effectively eliminating shadows and reflections, and further improving image acquisition quality.

[0023] like Figure 5 As shown, the brake disc ventilation duct detection device also includes a supplementary light source 270 and a mounting base 280. In this embodiment, the rotating platform 230 is a hollow rotating platform, which is an existing structure, and its specific structure will not be described in detail. The rotating platform 230 has a through-hole first opening 231 at its center, and the brake disc 1 has a through-hole second opening 11 at its center. The supplementary light source 270 passes through the first opening 231 and the second opening 11 to provide supplementary lighting for the ventilation duct 10. The mounting base 280 is fixed on the frame 210, and the supplementary light source 270 is fixed on the mounting base 280. The supplementary light source 270 illuminates outward from the center of the brake disc, and the light is scattered along the inner wall of the ventilation duct, making the clear details of the internal structure of the ventilation duct fully visible, effectively enhancing the industrial camera 240's ability to identify blockages, cracks, and casting defects inside the ventilation duct.

[0024] like Figure 3 As shown, a light-blocking plate 211 is fixed on the frame 210. The light-blocking plate 211 surrounds the outer periphery of the rotating platform 230, and a shooting port 2110 is opened on the side of the light-blocking plate 211 closest to the industrial camera 240. The light-blocking plate 211 can effectively isolate external ambient light interference, prevent stray light from entering the field of view of the industrial camera 240, and ensure the contrast and clarity of image acquisition.

[0025] like Figure 1 As shown, the transport assembly 400 includes a three-axis motion module 410 and a suction cup 420. The three-axis motion module 410 drives the suction cup 420 to move, and the suction cup 420 grips the brake disc 1. Under the command of the control system, the three-axis motion module 410 precisely executes the X, Y, and Z axis linkage to position the suction cup 420 to a designated position. In this embodiment, the suction cup is an electromagnetic suction cup, which uses electromagnetic force to attract the brake disc, avoiding damage to the workpiece caused by contact gripping.

[0026] like Figure 2 As shown, both the feeding conveyor line 100 and the unloading conveyor line 300 are equipped with multiple rollers 110 for transporting the brake disc 1.

[0027] like Figure 2 As shown, baffles 120 are respectively installed on the loading conveyor line 100 and the unloading conveyor line 300. The baffles 120 are used to limit the brake disc 1. The baffles 120 can prevent the brake disc from shifting or tipping over during the conveying process, ensuring that the loading and unloading process is stable and reliable.

[0028] The loading conveyor line 100 and the unloading conveyor line 300 are respectively inclined to the horizontal plane, so that the brake disc 1 moves automatically from the loading end of the loading conveyor line 100 / unloading conveyor line 300 to the unloading end of the loading conveyor line 100 / unloading conveyor line 300 under the action of gravity. The inclined conveyor lines, combined with the auxiliary rolling of the roller 110, effectively improve the transmission efficiency and stability of the brake disc 1 during the loading and unloading process, and can achieve automatic sliding without additional power drive, thus reducing energy consumption.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
