[0002] At present, with the rapid development of the automobile industry, the quality inspection technology of automobile parts is also constantly improving. As an important external component of the vehicle, the automobile bumper not only protects the vehicle body, but also directly affects the overall appearance and safety of the vehicle. Therefore, higher requirements are put forward for the appearance inspection technology of the bumper. In the related technology, a phase segregation method visual system is usually used to inspect the appearance of the bumper. Specifically, the bumper to be inspected is first fixed on the inspection device, and then the inspection module with integrated light source and camera group is driven by a robotic arm to perform mobile inspection on the bumper.

[0003] Regarding the above-mentioned related technologies: Since the bumper has a curved structure, it is easy to complicate the movement trajectory of the robot arm, and after the inspection is completed, the bumper needs to be removed from the inspection device and transported to the next workstation. The overall operation steps are complicated, which can easily lead to reduced inspection efficiency. Summary of the invention

[0004] In order to improve detection efficiency, the present application provides a bumper 3D scanning detection device.

[0005] The present application provides a 3D scanning and detection device for a bumper, which adopts the following technical solution: A bumper 3D scanning detection device, comprising: Conveying mechanism; The detection mechanism includes a bracket, a guide component and an imaging module. The bracket is arranged close to the conveying mechanism, the guide component is arranged on the bracket, and the imaging module is arranged on the guide component and located above the conveying mechanism. When the conveying mechanism conveys the bumper, the guide component is used to guide the imaging module to move following the change of the curvature of the bumper surface.

[0006] By adopting the above technical solution, the conveying mechanism can stably convey the bumper to the detection position and continuously convey the bumper to ensure the continuity and stability of the detection process. During this process, the bracket and the guide assembly work together to enable the imaging module to always maintain an accurate positional relationship when the curvature of the bumper surface changes, so that the imaging module can shoot at different angles and positions, further improving the comprehensiveness of the detection and ensuring that problems such as appearance particle size, color differences, and fastener missing can be discovered and handled in a timely manner. This design not only improves the detection accuracy, but also reduces the time required to transport and position the bumper, allowing the bumper to enter the detection area continuously and stably without the need to use manual or robotic arms to place the bumper one by one at the detection position, thereby greatly improving the continuity and efficiency of the detection.

[0007] Optionally, the guide assembly includes an arc-shaped rack, a gear, a guide drive and a mounting seat, the arc-shaped rack is arranged on the bracket and along the conveying direction of the conveying mechanism, the mounting seat is slidably arranged on the bracket, the guide drive and the imaging module are respectively arranged on the mounting seat, and the gear is arranged on the output end of the guide drive and meshes with the arc-shaped rack.

[0008] By adopting the above technical solution, when the conveying mechanism drives the bumper through the bracket, the guide drive member works to drive the gear to rotate, and the gear and the arc-shaped rack mesh with each other, so that the gear drives the mounting seat and the imaging module to move smoothly along the predetermined trajectory through the guide drive member, thereby facilitating the imaging module to perform a comprehensive scan of the bumper to avoid the scanning blind area caused by the fixed position. At the same time, the meshing action of the gear and the arc-shaped rack ensures high-precision position control and improves the adaptability and detection accuracy of the imaging module to different parts of the bumper. This design not only improves the detection efficiency, but also effectively reduces the false detection and missed detection caused by human factors, thereby ensuring the consistency of product quality.

[0009] Optionally, the imaging module includes a first detection camera and a stripe light source, the first detection camera and the stripe light source are respectively arranged on the mounting seat, and the first detection camera is used to detect the front side of the bumper.

[0010] By adopting the above technical solution, the first detection camera is used to detect the front of the bumper, and the first detection camera can move with the movement of the mounting base, so that the first detection camera can fully capture the surface image of the bumper at different angles and positions, ensuring that all key areas are covered, especially complex corners. This can more accurately identify problems such as particle size and color differences on the surface of the bumper, improve detection accuracy and reliability, and effectively prevent defective products from flowing into the client. At the same time, multi-angle light source illumination can also reduce the impact of shadows and reflections, further improving the detection effect.

[0014] By adopting the above technical solution, the driving component can drive the turntable to rotate, so that the multiple sets of sliding assemblies set on the turntable can sequentially transfer the bumper to be inspected from the first conveying assembly to the second conveying assembly. This design not only improves production efficiency, but also ensures the stability and safety of the bumper during transportation. At the same time, the grabbing assembly on each set of sliding assemblies can accurately grab the bumper, avoiding damage or position displacement caused by improper operation. In addition, the design of multiple sets of sliding assemblies can also achieve continuous operation, further improving the overall operation efficiency and reliability of the production line.

[0015] Optionally, both the first conveying assembly and the second conveying assembly are provided with a clearance groove, and the sliding assembly can drive the grabbing assembly to be inserted into the clearance groove; The grabbing assembly includes a lifting drive member, a support block and a magnetic member. The lifting drive member is arranged on the sliding assembly, the support block is arranged on the lifting drive member, the magnetic member is arranged on the support block, and the magnetic member is used to adsorb the bumper.

[0016] By adopting the above technical solution, when the bumper needs to be transported, the sliding assembly drives the lifting drive member to be inserted into the clearance groove. At this time, the support block is located below the bumper, and then the lifting drive member is used to drive the support block to move, so that the magnetic suction member can adsorb the bumper, thereby facilitating the bumper to be removed from the first conveying assembly and transported to the turntable. Then, the turntable is rotated so that the bumper is transported to the second conveying assembly, thereby facilitating the transportation of the bumper. In this process, the lifting drive member can adjust the height of the support block to ensure that the magnetic suction member can accurately contact and adsorb the bumper to prevent the bumper from moving or falling off during transportation and inspection.

And when the support block lifts the bumper, the support block can make the bumper and the second detection camera at the best detection distance, so that the second detection camera can effectively identify structural defects on the back of the bumper, such as whether fasteners such as fastening screws and springs are missing, etc., which is conducive to improving detection accuracy and reliability, reducing the flow of defective products into the market, and reducing the risk of customer complaints.

In this embodiment, the driving component 32 is a motor, so that the driving component 32 is used to drive the turntable 33 to rotate.

[0039] Two sets of sliding assemblies 34 are provided on the turntable 33, and each set of sliding assemblies 34 is provided with a grabbing assembly 35, and the sliding assemblies 34 can drive the grabbing assembly 35 to be inserted into the clearance groove 13, so as to facilitate the use of the grabbing assembly 35 to grab the bumper 4, so as to transfer the bumper 4 to the turntable 33 for temporary storage. In other embodiments, multiple sets of sliding assemblies 34 can also be provided, and the multiple sets of sliding assemblies 34 are evenly distributed on the turntable 33 to improve the caching capacity of the cache mechanism 3.

[0040] The sliding assembly 34 includes a sliding drive member 341 and a sliding seat 342. The sliding drive member 341 is mounted on the rotating disk 33, the sliding seat 342 is slidingly arranged on the rotating disk 33 and is fixedly connected to the sliding drive member 341, and the grab assembly 35 is arranged on the sliding seat 342, and the sliding seat 342 can be inserted into the clearance groove 13. In this embodiment, the sliding drive member 341 is a cylinder, so that the sliding drive member 341 can be used to drive the sliding seat 342 to approach or move away from the rotating disk 33.

[0041] Reference Figure 3 The grab assembly 35 includes a lifting drive member 351, a support block 352 and a magnetic member 353. The lifting drive member 351 is mounted on the sliding seat 342, and the support block 352 is fixedly connected to the lifting drive member 351. In this embodiment, the lifting drive member 351 is a cylinder, so that the lifting drive member 351 is used to drive the support block 352 to rise and fall.

[0042] Reference Figure 1 and Figure 3 , there are two support blocks 352, the two support blocks 352 are respectively fixedly connected to the lifting drive member 351, and the two support blocks 352 are spaced apart from each other. The number of magnetic suction members 353 is equal to the number of support blocks 352, and one magnetic suction member 353 is fixedly connected to one support block 352. In this embodiment, the magnetic suction member 353 is an electromagnet, so that the bumper 4 can be easily adsorbed by the magnetic suction member 353.

[0043] When the bumper 4 needs to be transferred to the turntable 33, the sliding drive 341 is first started, and the sliding drive 341 drives the sliding seat 342 to be inserted into the clearance groove 13 on the first conveying assembly 11, and the sliding seat 342 drives the lifting drive 351, the support block 352 and the magnetic member 353 to move, so that the support block 352 and the magnetic member 353 are located below the bumper 4 to be transferred, and then the lifting drive 351 is started, and the lifting drive 351 drives the support block 352 to rise, so that the support block 352 is attached to the back of the bumper 4, and the magnetic member 353 absorbs the bumper 4, so as to facilitate the removal of the bumper 4 from the first conveying assembly 11. Then, the sliding drive 341 works in the reverse direction to transfer the bumper 4 to the turntable 33, so as to facilitate the temporary storage of the bumper 4 on the turntable 33.

[0044] When the bumper 4 needs to be transferred to the second conveyor assembly 12, the driving component 32 works to drive the turntable 33 to rotate, and the turntable 33 drives the bumper 4 to rotate, so that the bumper 4 to be inspected is close to the second conveyor assembly 12. Then the sliding driving member 341 is started to insert the sliding seat 342 into the clearance groove 13 on the second conveyor assembly 12, so as to facilitate the transfer of the bumper 4 to the second conveyor assembly 12.

[0045] Reference Figure 1and Figure 3 The support block 352 is provided with an anti-skid pad 354, which can increase the friction between the support block 352 and the bumper 4, prevent the bumper 4 from shifting or falling due to sliding during the grasping process, and ensure the stability and reliability of the detection process. At the same time, the anti-skid pad 354 can also reduce the risk of scratching the surface of the bumper 4, and protect the quality and appearance integrity of the bumper 4.

[0046] In another preferred embodiment, the buffer mechanism 3 may not be provided, and the bumper 4 may be directly transported to the detection mechanism 2 for detection by the transport mechanism 1 .

[0047] Reference Figure 4 and Figure 5 The detection mechanism 2 includes a bracket 21, a guide assembly 22 and an imaging module 23. The bracket 21 is arranged close to the second conveying assembly 12, the guide assembly 22 is arranged on the bracket 21, and the imaging module 23 is arranged on the guide assembly 22 and located above the second conveying assembly 12.

[0048] The bracket 21 is made of a metal frame to provide a stable support base. The guide assembly 22 includes an arc-shaped rack 221, a gear 222, a guide drive 223 and a mounting seat 224. The arc-shaped rack 221 is mounted on the bracket 21 and arranged along the conveying direction of the second conveying assembly 12, and the arc-shaped rack 221 is made of stainless steel and has strong corrosion resistance.

[0049] The mounting seat 224 is slidably disposed on the bracket 21, and the sliding direction of the mounting seat 224 is the same as the length direction of the arc-shaped rack 221. The guide drive 223 and the imaging module 23 are respectively mounted on the mounting seat 224, the gear 222 is fixedly connected to the output end of the guide drive 223, and the gear 222 and the arc-shaped rack 221 are meshed with each other. In this embodiment, the guide drive 223 is a servo motor, so that the guide drive 223 can be used to drive the gear 222 to rotate, thereby facilitating the driving of the mounting seat 224 to slide, so as to accurately control the moving speed and position of the imaging module 23.

[0050] Reference Figure 1 and Figure 5 The imaging module 23 includes a first detection camera 231 and a stripe light source 232. The first detection camera 231 and the stripe light source 232 are respectively mounted on the mounting seat 224, and when the first detection camera 231 and the stripe light source 232 are located at the initial position, the first detection camera 231 and the stripe light source 232 can correspond to the corner position of the bumper 4.

[0051] When the stripe light source 232 is on, the stripe light source 232 can form a stripe light field, so that the surface defects of the bumper 4 in the stripe light field appear more obvious, so that the first detection camera 231 can accurately detect the bumper 4 .

[0052] When the bumper 4 passes through the bracket 21 (refer to Figure 4 ), the guide driving member 223 works to drive the mounting base 224 to move smoothly along a predetermined trajectory, and the mounting base 224 drives the first detection camera 231 and the stripe light source 232 to move, thereby facilitating the first detection camera 231 to adapt to the change of the surface curvature of the bumper 4 to accurately detect the front and corner positions of the bumper 4.

[0053] After inspecting one bumper 4, the guide driving member 223 works in the reverse direction to drive the first inspection camera 231 to reset. During this process, the turntable 33 drives another bumper 4 to be inspected to rotate toward the second conveying assembly 12 to prepare for the next inspection, thereby reducing production stagnation caused by waiting time, avoiding mechanical wear and increased energy consumption caused by frequent start and stop of the conveying mechanism 1, and thus improving inspection efficiency.

[0054] In addition, when the production demand of bumpers 4 increases, the inspection demand of bumpers 4 in the same time also increases. At this time, bumpers 4 that cannot be inspected in time within a unit time can be temporarily stored on the turntable 33 to avoid multiple bumpers 4 being blocked on the first conveying assembly 11, further reducing the possibility of production stagnation.

[0055] Reference Figure 1 A second detection camera 36 is installed on the sliding seat 342. The second detection camera 36 is located below the support block 352, and the second detection camera 36 is located between the two support blocks 352, so that the support block 352 is not easy to interfere with the second detection camera 36. Therefore, the second detection camera 36 can be used to accurately detect the back structure of the bumper 4 without affecting the grasping, thereby improving the detection accuracy and reliability.

[0056] It should be noted that in the embodiment of the present application, the first detection camera 231 can accurately detect the appearance defects, color differences, mixed or missing colors of decorative strips and skins of the bumper 4, and the second detection camera 36 can accurately detect the missing of fasteners such as fastening screws or spring leaves on the back of the bumper 4, so as to achieve a comprehensive inspection of the bumper 4.

[0057] The implementation principle of the bumper 3D scanning detection device of the embodiment of the present application is as follows: when the bumper 4 needs to be detected, the first conveying assembly 11 conveys the bumper 4 to be detected to the turntable 33. At the same time, the sliding drive member 341 works to drive the sliding seat 342 to be inserted into the corresponding clearance groove 13, so that the support block 352 is located below the bumper 4 to be detected, and then the lifting drive member 351 is started to make the support block 352 fit on the back of the bumper 4, and the magnetic suction member 353 absorbs the bumper 4.

[0058] Next, the sliding drive member 341 works in reverse to transfer the bumper 4 to the turntable 33. At the same time, the second detection camera 36 detects the back of the bumper 4. The sliding drive member 341 is started again, and the sliding drive member 341 drives the sliding seat 342 to be inserted into the clearance groove 13 of the second conveying assembly 12 to transfer the bumper 4 to the second conveying assembly 12, and the second conveying assembly 12 conveys the bumper 4 to the next process. In this process, the guide drive member 223 works to drive the mounting seat 224 to move, and the mounting seat 224 drives the first detection camera 231 and the stripe light source 232 to move, so as to facilitate the use of the first detection camera 231 to detect the front appearance of the bumper 4.

[0059] Finally, after the inspection is completed, the second conveying assembly 12 conveys the bumper 4 to the next process to classify the bumper 4 according to the inspection result, thereby completing the inspection process of the bumper 4 .

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
