Description

Technical Field

[0001] This utility model belongs to the field of automotive stamping parts inspection, specifically, it relates to an automotive stamping parts inspection device. Background Technology

[0002] As a core component of the vehicle body structure, chassis system, and interior components, automotive stamping parts directly determine the vehicle's assembly compatibility, driving safety, and appearance quality through their dimensional accuracy and surface quality. Statistics show that a single passenger car uses thousands of stamping parts, covering various types such as engine hoods, door panels, anti-collision beams, and chassis crossbeams. During the stamping process, these parts are highly susceptible to defects such as dimensional deviations, surface dents, cracks, and missing punches due to factors like die wear, pressure parameter fluctuations, and sheet metal springback. Therefore, efficient and accurate inspection is crucial for ensuring product quality and reducing rework costs in stamping parts production lines. However, existing inspection equipment requires manual flipping of the stamping parts after inspecting the upper surface (top surface) before inspecting the lower surface (bottom surface). This manual flipping increases the workload and labor costs for operators.

[0003] Chinese patent publication number CN222598851U discloses an inspection device for automotive stamping parts. The device uses a clamping mechanism to clamp the automotive stamping parts on both sides and a support mechanism on both sides to support the bottom surface of the automotive stamping parts. By driving a rotating gear to rotate, the clamping mechanism drives the automotive stamping parts to rotate, thereby achieving the flipping of the automotive stamping parts. However, when using this device, the stamping parts need to be transported onto the device for inspection. The overall operation process is cumbersome, resulting in a reduction in overall inspection efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] Please see Figure 1-7As shown, this embodiment provides an automotive stamping part inspection device, including two sets of conveyor belt mechanisms 1 and a flipping component 5, which is disposed between the two sets of conveyor belt mechanisms 1. The two sets of conveyor belt mechanisms 1 are each provided with a cleaning component 4 and an inspection device 3 in sequence along their conveying direction. The flipping component 5 includes two fixed plates 51, which are symmetrically fixedly installed between the two sets of conveyor belt mechanisms 1. A rotating shaft 55 is rotatably provided on the two fixed plates 51. A clamping component 56 for clamping the stamping part is provided on the rotating shaft 55. A first gear 53 and a first cylinder 54 are sleeved and fixedly installed on the rotating shaft 55 and are fixedly installed on the conveyor belt mechanism 1. A first rack 52 is fixedly installed on the telescopic end of the first cylinder 54. The first rack 52 meshes with the first gear 53 and is slidably disposed on the fixed plate 51.

[0040] Specifically, when the stamped part moves to the bottom of the cleaning component 4, the external control device controls the cleaning component 4 to clean the surface of the stamped part. Then, as the conveyor belt mechanism 1 continues to convey the part, it moves to the bottom of the detection device 3, where the surface of the stamped part is detected. Afterwards, the conveyor belt mechanism 1 moves the stamped part into the clamping component 56 of the flipping component 5. The external control device controls the two sets of conveyor belt mechanisms 1 to achieve continuous conveying of the stamped part. The flipping component 5 is installed between the two sets of conveyor belts to flip the stamped part. When the stamped part is conveyed from the first set of conveyor belts to the position of the flipping component 5, the external control device controls the clamping component 56 to clamp the stamped part, and then controls... The first cylinder 54 of the equipment extends and retracts to drive the first rack 52 to slide. Through the meshing transmission between the first rack 52 and the first gear 53, the rotating shaft 55 is driven to rotate, realizing the 180° flipping of the stamped part. After the flipping is completed, the clamping assembly 56 is released, and the stamped part is conveyed to the second set of conveyor belts. At the same time, the two sets of conveyor belts are sequentially equipped with cleaning components 4 and inspection equipment 3 along the conveying direction to clean and inspect the surface of the stamped part. The overall structure has a high degree of automation. The flipping assembly 5 realizes the automatic switching between the front and back sides of the stamped part. With the inspection equipment 3 of the two sets of conveyor belts, the double-sided inspection of the stamped part can be completed at one time without manual flipping, reducing manual intervention, reducing labor intensity, and improving inspection efficiency.

[0041] It should be noted that in this embodiment, the two sets of conveyor belt mechanisms 1 are arranged opposite to each other along the flipping component 5 and are arranged adjacent to each other. Their working principle and structure are existing technologies. Furthermore, in order to ensure the automated detection of the stamped parts on the conveyor belt mechanism 1 by the flipping component 5, the detection device 3 and the cleaning component 4, multiple sets of photoelectric sensors can be set on the conveyor belt mechanism 1. The multiple sets of photoelectric sensors are arranged along the length direction of the conveyor belt mechanism 1 and are connected to the signal of the external control device.

[0042] In this embodiment, as Figure 1 , Figure 2 and Figure 7As shown, the clamping assembly 56 includes a mounting box 566, which is fixedly mounted on the rotating shaft 55. Two fixing sleeves 565 are symmetrically fixedly mounted on the mounting box 566. Guide rods 564 are movably installed through and within each fixing sleeve 565. Two rotating plates 561 are arranged opposite to each other along the mounting box 566. Clamping plates 562 are fixedly mounted on the ends of the two rotating plates 561 opposite to the mounting box 566. The two rotating plates 561 are respectively connected to the guide rods 564 within the two fixing sleeves 565. A fixed connection is provided within the mounting box 566, which houses a drive mechanism 563 for driving the two rotating plates 561 to move relative to each other. The drive mechanism 563 includes two second racks 5632, which pass through and are movably mounted within the mounting box 566. The two second racks 5632 are arranged opposite to each other within the mounting box 566. A second gear 5633, meshing with the two second racks 5632, is rotatably mounted within the mounting box 566. The ends of the two second racks 5632 facing away from the second gear 5633 are respectively engaged with the two rotating plates 561. A rotating plate 561 is fixedly connected to a second cylinder 5631, which is fixedly installed inside the mounting box 566. The telescopic end of the second cylinder 5631 extends to the outside of the mounting box 566 and is fixedly connected to one of the rotating plates 561. Specifically, when it is necessary to clamp the stamped part, the second cylinder 5631 directly pushes one of the rotating plates 561 to move when it telescopically extends. The rotating plate 561 drives the second rack 5632 connected to it to slide. Through the meshing of the second rack 5632 and the second gear 5633, the other second rack 5632 is driven to slide in the opposite direction, thereby driving the other rotating plate 561 to move in the opposite direction synchronously, realizing the synchronous opening and closing of the two clamping plates 562, realizing the clamping and releasing of the stamped part. The cooperation between the guide rod 564 and the fixed sleeve 565 ensures that the rotating plate 561 moves smoothly, avoids the stamped part from shifting during the clamping process, and improves the clamping stability. At the same time, it can be adapted to stamped parts of different sizes (such as small brackets to large cover parts), enhancing the versatility of the device.

[0043] In this embodiment, as Figure 7 As shown, an anti-slip pad 6 is fixedly installed on the clamping plate 562, and a limit plate 7 is fixedly installed on the end of the guide rod 564 away from the rotating plate 561. Specifically, the anti-slip pad 6 on the clamping plate 562 is made of rubber or silicone. When clamping the stamping part, it increases the friction to prevent the stamping part from slipping and falling off during the flipping or conveying process.

[0044] In this embodiment, as Figures 1 to 5As shown, the cleaning component 4 includes two support plates 8, which are symmetrically fixedly installed on the conveyor belt mechanism 1. Each support plate 8 is provided with a mounting plate 45, and a dust collection cylinder 41 is fixedly installed between the two mounting plates 45. A vacuum cleaner 46 is fixedly installed on the conveyor belt mechanism 1, and the vacuum cleaner 46 is connected to the dust collection cylinder 41 via a pipe. A rotating rod 42 is rotatably mounted between the two mounting plates 45. A motor 44 for driving the rotating rod 42 is fixedly installed on the mounting plate 45. Multiple flexible bristles 43 are fixedly installed on the rotating rod 42 circumferentially. Specifically, when the stamping part moves to the bottom of the cleaning component 4 along the conveyor belt mechanism 1, the flexible bristles 43 abut against the top of the stamping part, and the motor 44 is driven by an external control device. The rotating rod 42 rotates, driving multiple flexible bristles 43 to sweep away dust and debris from the surface of the stamped parts. At the same time, the dust collection device 46 sucks the dust raised by the bristles into the dust collection cylinder 41 through the pipe and into the dust collection device 46. The cleaning component 4 pre-treats and removes impurities from the surface of the stamped parts, avoiding dust interference with the recognition accuracy of the detection device 3 (such as the industrial camera 32) and reducing the false judgment rate. The flexible bristles 43 can adapt to the curved or uneven structure of the stamped parts, cleaning without dead corners and without damaging the surface of the workpiece. The dust collection function prevents dust from spreading to the workshop environment, balancing cleaning effect and production environment cleanliness. It should be noted that in this embodiment, the structure of the dust collection device 46 is the prior art. For details, please refer to the structure and working principle of the vacuum cleaner in the prior art.

[0045] In this embodiment, as Figures 1 to 5 As shown, both support plates 8 are equipped with adjustment components 9 for adjusting the position of the mounting plate 45 on them. The adjustment component 9 includes an adjustment screw 92 and two movable rods 91. The adjustment screw 92 passes through and is threadedly connected to the mounting plate 45. The adjustment screw 92 is rotatably mounted on the support plate 8. The two movable rods 91 are fixedly mounted on the support plate 8 along the adjustment screw 92. The two movable rods 91 pass through and are movably mounted on the mounting plate 45. A baffle 2 is fixedly installed at the end of each movable rod 91 away from the support plate 8. Specifically, by rotating the adjustment screw 92, the mounting plate 45 can be driven to move up and down along the two movable rods 91 (because the adjustment screw 92 is threadedly connected to the mounting plate 45, the movable rods 91 play a guiding role), thereby adjusting the distance between the cleaning component 4 and the conveyor belt to adapt to stamped parts of different thicknesses, thereby flexibly adjusting the cleaning height, ensuring that the bristles are tightly attached to the surface of the stamped parts, and improving the cleaning effect.

[0046] In this embodiment, as Figures 1 to 6As shown, the inspection equipment 3 includes a fixed frame 31 fixedly mounted on the conveyor belt mechanism 1, and multiple sets of industrial cameras 32 and supplementary lights 33 fixedly mounted on the fixed frame 31. Specifically, the inspection equipment 3 is equipped with multiple sets of industrial cameras 32 (including 2D / 3D cameras) and supplementary lights 33 through the fixed frame 31. The supplementary lights 33 provide uniform illumination. The industrial cameras 32 capture images of the stamped parts from different angles. The image processing algorithm identifies surface defects (such as scratches and dents) and dimensional deviations (such as aperture and contour). Multiple cameras capture images from multiple angles to achieve full surface coverage inspection of the stamped parts, avoid blind spots, and improve the defect detection rate. The supplementary lights 33 eliminate ambient light interference, ensure image clarity, and provide high-quality data for algorithm recognition. The industrial cameras 32 have a fast response speed (millisecond level) to meet the high-speed inspection requirements of the production line.

[0047] Working principle:

[0048] When the stamped part moves to the bottom of the cleaning component 4, the external control device controls the cleaning component 4 to clean the surface of the stamped part. Then, as the conveyor belt mechanism 1 continues to convey the part, it moves to the bottom of the detection device 3, where the surface of the stamped part is inspected. Afterwards, the conveyor belt mechanism 1 moves the stamped part into the clamping component 56 of the flipping component 5. The external control device controls the two sets of conveyor belt mechanisms 1 to achieve continuous conveying of the stamped part. The flipping component 5 is installed between the two sets of conveyor belts to flip the stamped part. When the stamped part is conveyed from the first set of conveyor belts to the position of the flipping component 5, the external control device controls the clamping component 56 to clamp the stamped part, and then the control device... The first cylinder 54 extends and retracts to drive the first rack 52 to slide. Through the meshing transmission between the first rack 52 and the first gear 53, the rotating shaft 55 is driven to rotate, realizing the 180° flipping of the stamped part. After the flipping is completed, the clamping assembly 56 is released, and the stamped part is conveyed to the second set of conveyor belts. At the same time, the two sets of conveyor belts are sequentially equipped with cleaning components 4 and inspection equipment 3 along the conveying direction to clean and inspect the surface of the stamped part. The overall structure has a high degree of automation. The flipping assembly 5 realizes the automatic switching between the front and back sides of the stamped part. With the cooperation of the inspection equipment 3 of the two sets of conveyor belts, the double-sided inspection of the stamped part can be completed at one time without manual flipping, reducing manual intervention, reducing labor intensity, and improving inspection efficiency.
