Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive stamping parts inspection technology, and in particular to an auxiliary device for visual inspection of surface defects in automotive stamping parts. Background Technology
[0002] The purpose of visual inspection of surface defects in automotive stamping parts is to ensure that, under the premise of controllable cost, the stamping parts and their final components, the body-in-white and the complete vehicle, meet the design requirements for quality, safety, performance and consistency.
[0003] However, existing technologies and traditional inspection systems typically rely on cameras positioned in fixed locations for inspection, resulting in limited inspection angles and fields of view, which can easily lead to missed or false detections, especially when the stamped parts have many surface details or complex shapes. Furthermore, most existing equipment requires manual intervention to adjust the camera position and angle, which not only increases operational complexity but also reduces the automation level and inspection efficiency of the production line. Manual adjustment is prone to introducing human error and cannot meet the demands of high-frequency production in a short period. Utility Model Content
[0004] The purpose of this invention is to solve the problem that traditional detection systems in the prior art usually rely on cameras in fixed positions for detection, which leads to limited detection angles and fields of view, and is prone to missed or false detections. Therefore, this invention proposes a visual inspection auxiliary device for surface defects of automotive stamping parts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a visual inspection auxiliary device for surface defects of automotive stamping parts, including a support platform, a rotating mechanism installed on the top of the support platform, and an inspection mechanism installed on one side of the top of the support platform; The testing mechanism includes a support frame, with sliding rods fixedly connected to both sides of the support frame. A lifting frame is slidably connected to the outer surface of the sliding rods. A first rotating frame is rotatably connected to the inner wall of one end of the lifting frame, and a second rotating frame is rotatably connected to the other end of the lifting frame. A first sliding block is slidably connected to the inner side of the first rotating frame, and a second sliding block is slidably connected to the inner side of the second rotating frame. The first and second sliding blocks are fixedly connected. A camera is fixedly installed on the inner wall of the first sliding block. A cylinder is installed at the center of the bottom of the support frame, and the output end of the cylinder is fixedly connected to the middle of the lifting frame.
[0006] Preferably, a first servo motor is installed on one side wall of the lifting frame, and a second servo motor is installed on the other side wall of the lifting frame.
[0007] Preferably, the output end of the first servo motor is fixedly connected to the second rotating frame, and the output end of the second servo motor is fixedly connected to the first rotating frame.
[0008] Preferably, the rotating mechanism includes a central column rotatably connected to the support platform, and a rotating plate is fixedly connected to the top of the central column.
[0009] Preferably, a limiting groove is formed on the outer surface of the rotating plate, and a limiting rod is slidably connected inside the limiting groove.
[0010] Preferably, the bottom of the limiting rod is fixedly connected to the support platform, and a third servo motor is installed at the top of the inner cavity of the support platform.
[0011] Preferably, the output end of the third servo motor is fixedly connected to a drive gear, and a driven gear fixedly connected to the central column is meshed on one side of the drive gear.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, during the defect detection process of automotive stamping parts, the first rotating frame serves as the main support structure. The first sliding block drives the second sliding block to slide, thereby adjusting the position of the camera mounted on the second rotating frame to achieve visual monitoring of different areas on the surface of the stamping part. When the second rotating frame rotates, the second sliding block acts in the opposite direction on the first sliding block, ensuring the optimization of the camera's lens angle and field of view, expanding its range of motion, and covering more detection areas. The movement of the camera is combined with a pneumatic drive system. The cylinder, through the cooperation of the lifting frame and the slide rod, enables the lifting frame to slide smoothly, avoiding image distortion or false detection caused by equipment vibration. The camera position can be flexibly adjusted according to the size and shape of the stamping part to ensure clear capture of the surface details of each stamping part. 2. In this utility model, the drive system of the third servo motor precisely controls the rotation of the active gear, thereby transmitting the meshing force to the driven gear, ensuring smooth force transmission and minimizing errors. The transmitted mechanical force then causes the central column to rotate, driving the rotating plate to perform precise circular motion. The movement of the rotating plate can be adjusted by controlling the trajectory and angle to precisely adjust the position of the stamped part, achieving comprehensive inspection. The multi-dimensional adjustment of the rotating plate allows for precise adjustment of the position of the stamped part, enabling all-round inspection from different angles. This control method improves the flexibility and adjustability of the inspection, avoids the problem of traditional inspection being limited by the viewing angle, and ensures the comprehensiveness and accuracy of the inspection.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0017] Example 1: As Figures 1-4 As shown, this utility model provides a visual inspection auxiliary device for surface defects of automotive stamping parts, including a support platform 1, a rotating mechanism 3 installed on the top of the support platform 1, and an inspection mechanism 2 installed on one side of the top of the support platform 1. The testing mechanism 2 includes a support frame 21, with slide rods 22 fixedly connected to both sides of the support frame 21. A lifting frame 23 is slidably connected to the outer surface of the slide rods 22. A first rotating frame 26 is rotatably connected to the inner wall of one end of the lifting frame 23, and a second rotating frame 27 is rotatably connected to the other end of the lifting frame 23. A first sliding block 261 is slidably connected to the inner side of the first rotating frame 26, and a second sliding block 271 is slidably connected to the inner side of the second rotating frame 27. The first sliding block 261 and the second sliding block 271 are fixedly connected. A camera 28 is fixedly installed on the inner wall of the first sliding block 261. A cylinder 29 is installed at the center of the bottom of the support frame 21, and the output end of the cylinder 29 is fixedly connected to the middle of the lifting frame 23.
[0018] A first servo motor 24 is installed on one side wall of the lifting frame 23, and a second servo motor 25 is installed on the other side wall of the lifting frame 23. The output end of the first servo motor 24 is fixedly connected to the second rotating frame 27, and the output end of the second servo motor 25 is fixedly connected to the first rotating frame 26.
[0019] The specific setup and function of this embodiment will be described in detail below. When inspecting defects in automotive stamped parts, the first rotating frame 26 serves as the main support structure. During rotation, it drives the movement of the second sliding block 271 via the first sliding block 261. Through a mechanical connection with the second sliding block 271, the first sliding block 261 can cause the second sliding block 271 to slide along the interior of the second rotating frame 27. This movement allows the camera 28 mounted on the second rotating frame 27 to adjust its position, thereby enabling visual inspection of different areas on the surface of the stamped part.
[0020] When the second rotating frame 27 begins to rotate, the second sliding block 271 acts in the opposite direction on the first sliding block 261, causing it to slide inside the first rotating frame 26. This opposing force ensures that the system can make precise lens adjustments, thereby optimizing the detection angle and field of view of the camera 28. Through this interaction, the range of motion of the camera 28 is expanded, thus covering more detection areas and achieving comprehensive detection of surface defects on stamped parts. In this process, the movement of the camera 28 is not simply mechanical, but is combined with a pneumatic drive system to stabilize the movement. Specifically, the cylinder 29 is driven by the cooperation of the lifting frame 23 and the slide bar 22, enabling the lifting frame 23 to slide smoothly along the surface of the slide bar 22. The force exerted by the cylinder 29 on the lifting frame 23 ensures that the entire device remains stable during the detection process, thereby avoiding image distortion or false detections caused by equipment vibration or instability. The precise lifting of the lifting frame 23 not only provides a stable working environment for the camera 28, but also allows for flexible adjustment of the position and angle of the camera 28 according to the different sizes and shapes of the stamped parts, ensuring that every detail on the surface of each stamped part can be clearly captured. This design enables rapid and accurate defect detection, ensuring quality control on efficient production lines.
[0021] Example 2: Figure 2 and Figure 4 As shown, the rotating mechanism 3 includes a central column 34 rotatably connected to the support platform 1, and a rotating plate 33 fixedly connected to the top of the central column 34. A limit groove 331 is formed on the outer surface of the rotating plate 33, and a limit rod 32 is slidably connected to the inner side of the limit groove 331. The bottom of the limit rod 32 is fixedly connected to the support platform 1, and a third servo motor 31 is installed at the top of the inner cavity of the support platform 1. A drive gear 35 is fixedly connected to the output end of the third servo motor 31, and a driven gear 36 fixedly connected to the central column 34 is meshed on one side of the drive gear 35.
[0022] The overall effect of this embodiment is that, during the detection process, the drive system of the third servo motor 31, through precise control, enables the drive gear 35 to achieve efficient and smooth rotation. As the drive gear 35 rotates, the meshing force between the gears is transmitted to the driven gear 36, causing the driven gear 36 to also begin to rotate. This process, through the high-precision matching of the transmission system, ensures the smooth transmission of force and minimizes errors in the mechanical transmission process.
[0023] As the driven gear 36 rotates, mechanical force is transmitted to the central column 34, causing it to begin rotating. At this point, the rotation of the central column 34 is not merely a simple rotation; it also drives the rotating plate 33 to perform precise circular motion through its connecting mechanism. During this circular motion, the relative position of the stamped part can be precisely changed by precisely controlling its trajectory and angle, thereby achieving precise adjustment of the stamped part.
[0024] This control method greatly improves the flexibility and adjustability of stamped parts during the inspection process, allowing for precise adjustment of the stamped parts' position to facilitate comprehensive inspection from multiple angles. Because the rotating plate 33 can be adjusted in multiple dimensions, the inspection system can avoid the problem of traditional inspection methods that limit omnidirectional inspection due to viewing angle restrictions, thereby improving the comprehensiveness and accuracy of the inspection.
[0025] In addition, the design of linking the central column 34 with the rotating plate 33 not only ensures the precise adjustment of the stamped part's position, but also allows for flexible changes in the inspection angle as needed during the inspection process, ensuring multi-angle and all-round inspection of the stamped part from different perspectives.
[0026] The device's operation and working principle are as follows: During the defect detection of automotive stamping parts, the rotation of the first rotating frame 26 drives the first sliding block 261 to move the second sliding block 271, causing the second sliding block 271 to slide along the inside of the second rotating frame 27, thereby adjusting the position of the camera 28. Simultaneously, when the second rotating frame 27 rotates, it acts in the opposite direction on the first sliding block 261 through the second sliding block 271, causing it to slide inside the first rotating frame 26. Through the linkage between the first sliding block 261 and the second sliding block 271, the position of the camera 28 can be quickly adjusted, achieving efficient visual inspection of the stamping part surface.
[0027] During the inspection process, cylinder 29 drives lifting frame 23 to slide up and down along slide bar 22 to ensure stable lifting process and facilitate flexible adjustment of camera 28 according to the position of stamped part.
[0028] Furthermore, the third servo motor 31 drives the drive gear 35 to rotate, which in turn rotates the central column 34 through meshing with the driven gear 36, thereby causing the rotating plate 33 to perform circumferential motion to adjust the position of the stamped part. This structure helps to achieve multi-angle inspection and improves the inspection effect and quality.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
