Description

Technical Field

[0001] This invention relates to the field of automotive parts inspection technology, and in particular to a multi-angle visual inspection device for automotive parts. Background Technology

[0002] Brake discs, steering knuckles, gearbox housings, and new energy motor housings—large and critical safety components in automobiles—directly affect the overall vehicle's driving safety. Industry quality inspection standards require that all outer walls, deep cavities, and undercut areas of these parts undergo thorough appearance and dimensional inspection without omission, and blind spots at clamping contact points are not permitted. These parts often have concave and convex cavities and thick reinforcing ribs; relying solely on single-sided clamping and single-sided imaging results in permanent obstruction of the clamping contact surface, making it impossible to detect fatal defects such as cracks, dents, and pores. To eliminate clamping blind spots, the industry commonly employs flip-type clamping equipment, achieving multi-faceted imaging by changing the workpiece's posture and clamping points, thereby improving the reliability of defect detection.

[0003] An investigation revealed that a Chinese patent discloses an automotive parts appearance visual imaging inspection device (publication number: CN219417255U). The device mainly includes a worktable, a stage, a gantry-type imaging inspection mechanism, and two sets of multi-angle clamping mechanisms arranged symmetrically on the left and right. Each clamping mechanism integrates a vertical adjustment component, a flip adjustment component, a rotation adjustment component, and a telescopic manipulator. Its core implementation method is to alternately release and release the workpiece by the manipulators on both sides and rotate them to switch the workpiece shooting posture by rotating them in place. The device uses a movable CCD camera on the top to collect images of six sides of the parts, thereby realizing the multi-angle appearance defect identification of metal parts.

[0004] Although the aforementioned patent relies on dual-sided mechanical grippers to achieve workpiece flipping and clamping point switching, reducing blind spots in single-sided clamping, this rigid gripper structure has inherent defects: limited clamping and opening stroke, poor adaptability to irregularly shaped parts, contact with the workpiece only in a narrow area, concentrated clamping force, easy slippage during flipping, insufficient stability when using a single gripper, and two-grip gripping will create two detection blind spots. Furthermore, the alternating hand-grip increases the number of processes and extends the cycle time. The hand-turning process can easily scratch the finished surface of the workpiece. Existing single and double rigid gripper solutions cannot meet the requirements of stable clamping, no blind spots, and high-efficiency detection. There is an urgent need for a detection mechanism that can simultaneously complete workpiece displacement and flipping and clamping point misalignment changes without the need for double-grip hand-turning.

[0005] Therefore, this application provides a multi-angle visual inspection device for automotive parts to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a multi-angle visual inspection device for automotive parts, so as to solve the problems of poor rigid gripper fit, gripping slippage, blind spots, inefficient inspection of easily scratched parts.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A multi-angle visual inspection device for automotive parts includes an inspection device body and multiple industrial cameras. A bracket is mounted on the inspection device body, and a mounting frame is mounted on the bracket. The multiple industrial cameras are respectively positioned above and below the mounting frame. Mounting plates are symmetrically fixed on the mounting frame, and mounting shafts are fixedly connected to both sides of the mounting frame. A support plate is connected to the bracket. A clamping assembly is provided within the mounting plate for flexibly clamping the sidewalls of irregularly shaped parts. The clamping assembly includes multiple positioning pins, a flexible metal bushing, and a third spring. An adjustment mechanism is provided between the bracket and the mounting shafts for adjusting the orientation and position of the clamped parts. The adjustment mechanism includes a movable block, two spiral frames, and a strip frame. A feedback mechanism is provided between the support plate and the mounting shafts. The feedback mechanism provides feedback on the rotation of the parts to the support plate, driving the support plate to support the parts and preventing the support plate from obstructing the rotation of the parts. The feedback mechanism includes a metal ball, a metal plate, an insert plate, two partitions, and a guide plate.

[0009] Optionally, the mounting plate has multiple cylindrical cavities, the positioning post is slidably connected in the cylindrical cavity, the third spring is installed in the cylindrical cavity, and the two ends of the third spring are fixedly connected to the positioning post and the inner wall of the cylindrical cavity, respectively. The flexible metal bushing is fixedly installed in the cylindrical cavity, and the positioning post slides through the flexible metal bushing. The cylindrical cavity area where the flexible metal bushing is installed has an oil injection hole.

[0010] Optionally, an annular frame is fixedly connected to the bracket, the mounting shaft is movably connected to the annular frame, two spiral frames and strip frames are alternately arranged and fixedly connected between the annular frames, the spiral frame and the strip frame are connected through the through groove, the movable block is fixedly connected to the side wall of the mounting shaft and movably connected in the through groove between the spiral frame and the strip frame, and a baffle is rotatably connected at the connection between the spiral frame and the strip frame.

[0011] Optionally, a connecting ring is rotatably connected to the mounting shaft, a connecting frame is fixedly connected to the connecting ring, and the connecting frame is slidably connected to the bracket. An mounting cylinder is fixedly connected to the end of the connecting frame, a sliding rod is slidably connected to the mounting cylinder, and a first spring is fixedly connected between the sliding rod and the mounting cylinder. The metal ball is fixedly connected to the sliding rod.

[0012] Optionally, a fixed frame is fixedly connected to the bracket, the metal plate and the two partitions are fixedly connected to the fixed frame, the metal ball abuts against the metal plate, one end of the guide plate is rotatably connected to the partition, and one end of the guide plate abuts against the metal plate.

[0013] Optionally, a mounting block is fixedly connected between the bracket and the fixing frame, one end of the insert plate is slidably connected in the mounting block, and the other end of the insert plate slides through the fixing frame and fits against the metal plate.

[0014] Optionally, an electromagnet is fixedly connected inside the mounting block, and an iron plate is fixedly connected to the insert plate, with the iron plate and the electromagnet being positioned opposite each other. Two round rods are fixedly connected inside the mounting block, and the round rods slide through the ends of the insert plate. A second spring is sleeved on the round rod, and the two ends of the second spring are fixedly connected to the insert plate and the mounting block, respectively.

[0015] Optionally, a mounting rod is rotatably connected to the bracket, the support plate is fixedly connected to the mounting rod, and a first cylinder is rotatably connected between the mounting rod and the bracket.

[0016] Optionally, a second cylinder and a telescopic rod are fixedly connected to the mounting bracket, and the end of the telescopic rod and the output end of the second cylinder are both fixedly connected to the mounting plate.

[0017] Optionally, a hydraulic rod is mounted on the main body of the testing equipment, and the output end of the hydraulic rod is rotatably connected to the mounting shaft.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above solution, the clamping assembly can flexibly clamp irregularly shaped automotive parts. Multiple positioning posts can adaptively conform to the concave and convex contours of the part's sidewall under the elastic force of the third spring. Combined with the sealing protection of the flexible metal bushing, multi-point circumferential flexible positioning is achieved. Compared with the traditional clamping method with narrow contact of rigid jaws, the multi-point uniform contact with the sidewall of the irregular workpiece disperses the force and makes it less prone to slippage during the flipping process. At the same time, it is compatible with various concave and convex irregular parts, solving the problems of limited opening and closing stroke of the original jaws and poor adaptability of clamping irregular parts. A single set of clamping mounting frame is set up, and the workpiece is temporarily supported by the telescopic tray to complete the replacement of the clamping point misalignment. There is no need for two sets of robotic arms to transfer parts between each other, avoiding the two visual blind spots caused by the double jaw clamping. At the same time, the workpiece transfer process is eliminated, the single-piece inspection cycle is shortened, and the workpiece's precision sealing surface is not scratched by the robotic arm during transfer.

[0020] The workpiece is simultaneously moved slightly and rotated 180° by the adjustment mechanism. With the industrial cameras arranged in layers, the bottom surface of the workpiece can be fully imaged after it is flipped. The accuracy of defect identification in deep cavity and undercut area is higher. It can truly realize full-size appearance inspection of the outer wall and cavity of the workpiece without blind spots, meet the stringent quality inspection standards of automotive safety key components, and change the clamping point without disassembly and re-clamping, eliminating clamping blind spots and improving the reliability of defect detection.

[0021] The feedback mechanism can transmit the flip signal to the tray by following the movement of the mounting axis, so that the tray can support the part after the part is flipped, which helps to improve the stability of the part during shooting. During the part flipping process, it automatically retracts to avoid the movement path and will not hinder the normal flipping and positioning of the part. It takes into account the stability of heavy workpiece clamping and support and the need for unobstructed imaging of the bottom camera throughout the process, and takes into account the detection stability and imaging quality.

[0033] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0034] like Figures 1 to 9 As shown, an embodiment of the present invention provides a multi-angle visual inspection device for automotive parts, including an inspection device body 1 and multiple industrial cameras 2. A bracket 3 is mounted on the inspection device body 1, and a mounting frame 4 is mounted on the bracket 3. The multiple industrial cameras 2 are respectively positioned above and below the mounting frame 4. Mounting plates 6 are symmetrically fixed on the mounting frame 4, and mounting shafts 7 are fixedly connected to both sides of the mounting frame 4. A support plate 8 is connected to the bracket 3. A clamping assembly is provided inside the mounting plate 6. The clamping assembly is used to flexibly clamp the sidewalls of irregularly shaped parts. The clamping assembly includes multiple positioning pins 34, a flexible metal bushing 36, and a third spring 35. An adjustment mechanism is provided between the frame 3 and the mounting shaft 7. The adjustment mechanism is used to adjust the orientation and position of the clamped parts. It can simultaneously complete the small feed displacement and 180° flipping of the workpiece. The adjustment mechanism includes a movable block 11, two spiral frames 18 and a strip frame 19. A feedback mechanism is provided between the pallet 8 and the mounting shaft 7. The feedback mechanism feeds back the flipping of the parts to the pallet 8. It is used to drive the pallet 8 to support the parts and prevent the pallet 8 from obstructing the flipping of the parts. The feedback mechanism includes a metal ball 24, a metal plate 25, an insert plate 28, two partitions 26 and a guide plate 27. It realizes the linkage between the clamping action and the rotation of the pallet 8 without the need for an additional timing control module.

[0035] like Figure 7 and Figure 9As shown, the mounting plate 6 has multiple cylindrical cavities. The positioning post 34 is slidably connected in the cylindrical cavity. The third spring 35 is installed in the cylindrical cavity, and its two ends are fixedly connected to the positioning post 34 and the inner wall of the cylindrical cavity, respectively. The flexible metal bushing 36 is fixedly installed in the cylindrical cavity, and the positioning post 34 slides through the flexible metal bushing 36. The cylindrical cavity area where the flexible metal bushing 36 is installed has an oil injection hole. It should be noted that an external oil tank is connected through the oil injection hole, and oil is injected and depressurized by a solenoid valve. The external solenoid valve introduces high-pressure oil through the oil injection hole to squeeze the flexible metal bushing 36 to hold the positioning post 34. The workpiece is locked synchronously at multiple points. Compared with the traditional single-line contact rigid gripper, the clamping force is uniform, and heavy workpieces are less likely to slip when flipped. After depressurization, the positioning post 34 automatically releases, and the clamping and release response speed is fast.

[0036] like Figures 3 to 5 As shown, a ring frame 12 is fixedly connected to the bracket 3, and the mounting shaft 7 is movably connected to the ring frame 12. Two spiral frames 18 and strip frames 19 are alternately arranged and fixedly connected between the ring frames 12. The spiral frames 18 and strip frames 19 are connected through slots. The movable block 11 is fixedly connected to the side wall of the mounting shaft 7 and movably connected in the through slot between the spiral frames 18 and strip frames 19. A baffle 20 is rotatably connected at the connection between the spiral frames 18 and strip frames 19. The baffle 20 restricts the movement direction of the movable block 11. The spiral frames 18 guide the synchronous linkage of translation and rotation, accurately control the workpiece flipping angle and feed distance, and achieve high positioning accuracy with repeated actions. There is no need for two separate sets of drives to control the displacement and flipping.

[0037] like Figure 6 and Figure 8As shown, a connecting ring 21 is rotatably connected to the mounting shaft 7, and a connecting frame 15 is fixedly connected to the connecting ring 21. The connecting frame 15 is slidably connected to the bracket 3. A mounting cylinder 22 is fixedly connected to the end of the connecting frame 15. A sliding rod 23 is slidably connected to the mounting cylinder 22, and a first spring 29 is fixedly connected between the sliding rod 23 and the mounting cylinder 22. A metal ball 24 is fixedly connected to the sliding rod 23. The first spring 29 continuously presses the metal ball 24 against the metal plate 25 to ensure the stability of the normal conductive circuit. A fixing frame 16 is fixedly connected to the bracket 3. The metal plate 25 and two partitions 26 are all fixedly connected to the fixing frame 16. The metal ball 24 abuts against the metal plate 25. One end of the guide plate 27 is rotatably connected to the partition 26, and the other end of the guide plate 27 abuts against the metal plate 25. The partition 26 limits the sliding stroke of the metal ball 24 to prevent conductive contact deviation and circuit breakage. A mounting block 17 is fixedly connected between the bracket 3 and the fixed frame 16. One end of the insert plate 28 is slidably connected inside the mounting block 17, and the other end of the insert plate 28 slides through the fixed frame 16 and fits against the metal plate 25. After the insert plate 28 is inserted, it can reliably cut off the power supply to the first cylinder 9 of the support plate 8, so that the support plate 8 can automatically avoid the clamping. An electromagnet 30 is fixedly connected inside the mounting block 17, and an iron plate 31 is fixedly connected on the insert plate 28. The iron plate 31 and the electromagnet 30 are positioned opposite each other. Two round rods 32 are fixedly connected inside the mounting block 17, and the round rods 32 slide through the ends of the insert plate 28. A second spring 33 is sleeved on the round rod 32, and the two ends of the second spring 33 are fixedly connected to the insert plate 28 and the mounting block 17 respectively. After the power is cut off, the second spring 33 automatically rebounds and pulls out the insert plate 28 so as not to hinder the restoration of the conductive circuit and affect the rotation of the support plate 8 to support the workpiece.

[0038] like Figure 2 and Figure 3 As shown, a mounting rod 10 is rotatably connected to the bracket 3, and the support plate 8 is fixedly connected to the mounting rod 10. A first cylinder 9 is rotatably connected between the mounting rod 10 and the bracket 3. A second cylinder 13 and a telescopic rod 14 are fixedly connected to the mounting frame 4. The end of the telescopic rod 14 and the output end of the second cylinder 13 are both fixedly connected to the mounting plate 6. A hydraulic rod 5 is installed on the main body 1 of the testing equipment. The output end of the hydraulic rod 5 is rotatably connected to the mounting shaft 7. The hydraulic output is stable, and there is no impact or shaking when the heavy load is turned over. The two second cylinders 13 push the mounting plate 6 to move towards each other in sync, ensuring that the positioning columns 34 on both sides are in sync with the workpiece, and there is no one-sided squeezing that causes the part to shift.

[0039] It should be noted that both the first cylinder 9 and the second cylinder 13 are press-fit single-acting cylinders. When air is supplied, the piston rod extends, and when air is cut off, the built-in spring automatically pushes the piston rod back. The structure is simple, and it can automatically reset without an external air source after power failure. The specific model and specifications of the first cylinder 9 and the second cylinder 13 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The working principle of the technical solution provided by this invention is as follows:

[0041] During the operation of this equipment, in the initial standby state, the metal ball 24 and the metal plate 25 are in contact, forming a conductive circuit. The first cylinder 9, which is electrically connected to the metal plate 25, is energized and drives the pallet 8 to rotate upward. The automotive safety component to be tested can be placed on the pallet 8, and the workpiece is initially positioned by relying on the pallet 8.

[0042] After the material is loaded, the second cylinder 13 pushes the two mounting plates 6 to move towards each other. Multiple positioning pins 34 extend and retract autonomously under the elastic force of the third spring 35, adaptively fitting the concave and convex sidewalls of the workpiece to achieve pre-flexible fitting. Then, the external solenoid valve opens and high-pressure oil is introduced into the outer wall of the metal flexible bushing 36 through the oil injection hole. The high-pressure oil squeezes the metal flexible bushing 36, hugs the positioning pins 34 that pass through, restricts positioning retraction, and locks the sidewalls of the workpiece at multiple points simultaneously to complete rigid positioning clamping. The metal flexible bushing 36 relies on high-pressure oil to squeeze and hug the positioning pins 34, and the solenoid valve controls the on and off of oil injection and pressure relief, which is a common existing hydraulic clamping technology.

[0043] The solenoid valve and electromagnet 30 are connected in series synchronously. During the oil supply and clamping stage, electromagnet 30 is energized synchronously. Electromagnet 30 attracts iron plate 31, which drives the insert plate 28 to slide along the round rod 32 and compress the second spring 33. It is inserted between metal ball 24 and metal plate 25, cutting off the conductive path between them. The first cylinder 9 is de-energized synchronously, driving the support plate 8 to rotate downwards and reset. The support plate 8 is completely separated from the bottom surface of the workpiece and no longer supports the clamped part. The bottom is unobstructed, allowing the industrial camera 2 below to capture the bottom surface image of the workpiece. The industrial camera 2 above takes pictures of the upper part of the part's appearance, and the industrial camera 2 below directly takes pictures of the initial exposed bottom surface of the part, completing the first round of multi-angle shooting.

[0044] Then, the hydraulic rod 5 is activated to push the mounting shaft 7 to move along the ring frame 12. At this time, the movable block 11 on the side wall of the mounting shaft 7, under the restriction of the baffle 20, first enters the through slot of the spiral frame 18 through the slot of the strip frame 19. Under the guidance of the spiral frame 18, it rotates and moves until the movable block 11 crosses the spiral frame 18 and enters the through slot of another strip frame 19. At this time, the mounting shaft 7 has driven the mounting frame 4 to complete a 180° rotation. The area that was originally clamped and blocked is fed a certain distance, and the original clamping position moves away from the original area. At the same time, the part is rotated. The upper industrial camera 2 detects the lower half of the part, and the lower industrial camera 2 detects the upper half of the part, so as to avoid the part being affected by light or partial obstruction and thus affecting the detection imaging.

[0045] Furthermore, during the displacement of the movable block 11, as the movable block 11 moves within the screw frame 18, the connecting frame 15 moves synchronously with the mounting shaft 7. The metal ball 24 compresses the first spring 29 via the guide plate 27 and moves onto the partition plate 26. The metal ball 24 and the metal plate 25 remain separated to prevent the upward rotation of the support plate 8 from affecting the rotation of the mounting frame 4. When the movable block 11 moves from the screw frame 18 into the strip frame 19, the metal ball 24 moves out from the end of the partition plate 26. With the reset action of the first spring 29, the metal ball 24 is pushed to contact the metal plate 25. The first cylinder 9 is energized and pushes the support plate 8 to rotate upward to support the parts.

[0046] After the workpiece is flipped into position, the second cylinder 13 drives the mounting plate 6 to reset. The solenoid valve is de-energized and briefly depressurizes, and the electromagnet 30 is simultaneously de-energized, no longer attracting the iron piece 31. Under the reset action of the second spring 33, the insert plate 28 is pushed back. Then, the hydraulic rod 5 drives the clamping assembly on the mounting frame 4 to slightly reset and shift. At this time, the movable block 11 on the mounting shaft 7 moves along the strip frame 19 and no longer drives the mounting shaft 7 to rotate. After resetting, the second cylinder 13 pushes the two mounting plates 6 to move towards each other again, and the multiple positioning pins 34 adaptively fit the concave part of the workpiece. The convex sidewall is pre-flexibly bonded, and then the solenoid valve and electromagnet 30 are energized. High-pressure oil is introduced into the outside of the flexible metal bushing 36 through the oil injection hole to squeeze the sidewall of the flexible metal bushing 36 to hold the positioning post 34 tightly. The electromagnet 30 attracts the iron plate 31, which drives the insert plate 28 to insert between the metal ball 24 and the metal plate 25, cutting off the conductive path between them. This causes the first cylinder 9 to lose power again, and the support plate 8 is reset and retracted downwards, without obstructing the industrial camera 2 below from taking pictures. The repositioned positioning post 34 abuts and clamps the displaced workpiece, changing the position of the clamping point to avoid obstruction.

[0047] The entire process can simultaneously achieve workpiece flipping and clamping point misalignment replacement with a single clamping mechanism, eliminating the need for two robotic arms to handle the workpiece. This prevents scratching the workpiece's precision-machined surface. The multi-point flexible clamping ensures uniform force distribution and prevents slippage during the flipping process. Two industrial cameras arranged vertically can completely capture images of the workpiece's front and back surfaces and cavity defects, meeting the requirement for full-surface, blind-spot-free inspection of safety components.

[0048] In addition, the electromagnet 30 is connected in series with the solenoid valve for synchronous control, realizing the linkage between the clamping action and the retraction action of the pallet 8. No separate timing controller is required, simplifying the electrical control logic of the whole machine. The spiral frame 18 and the strip frame 19 in the adjustment mechanism, together with the baffle 20 and the limiting block 11, can accurately control the workpiece displacement distance and flipping angle, ensuring the repeatability of positioning accuracy for multiple clamping and flipping actions, and is suitable for the detection of various irregular medium and large safety parts such as brake discs and gearbox housings.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
