Detailed Description of the Invention

[0022] The following is combined with the attached Figures 1 - 3A further detailed description of the present application is provided.

[0023] An embodiment of the present application discloses a stamping detection device for a luggage case cover. Referring to Figures 1 - 3 , a stamping detection device for a luggage case cover includes a frame 1. Cover fixing components 2 are installed on both opposite sides of the frame 1. The cover fixing component 2 includes two brackets 202 that move along the X-axis. A clamp 204 is rotatably installed on the bracket 202. The automotive luggage case cover is clamped by the clamp 204, and the power is used to drive the clamp 204 to drive the luggage case cover to rotate, realizing multi-faceted flipping detection. An adjustment component 3 is installed on the top of the frame 1. The adjustment component 3 includes an electric guide rail 302 rotatably installed at the lower end of the frame 1. An electric slider 303 is installed on the electric guide rail 302. A three-axis parallel robot 4 is installed at the lower end of the electric slider 303. By the horizontal rotation of the electric guide rail 302, the horizontal direction of the electric slider 303 can be adjusted. Cooperating with the movement of the electric slider 303 along the electric guide rail 302, the position of the three-axis parallel robot 4 can be adjusted arbitrarily in the radial direction. An image acquisition device 5 is installed at the output end of the three-axis parallel robot 4. The three-axis parallel robot 4 can freely adjust the detection angle of the image acquisition device 5 as needed, realizing the detection of the automotive luggage case cover at different angles and different positions.

[0024] Referring to Figure 2 , a driving motor 203 is installed on the bracket 202. The output end of the driving motor 203 is in transmission connection with the clamp 204. Telescopic cylinders 201 are installed on both sides of the driving motor 203 on the bracket 202. The fixed end of the telescopic cylinder 201 is fixedly connected to the frame 1 by bolts. By controlling the telescopic movement of the telescopic cylinder 201, the distance between the two clamps 204 is adjusted to adapt to the luggage case covers of different models of automobiles. By driving the clamp 204 to rotate with the luggage case cover by the driving motor 203, the operation of changing the surface of the luggage case cover is realized, facilitating the multi-faceted detection of the luggage case cover by the image acquisition device 5.

[0025] Referring to Figure 1 , the clamp 204 includes a U-shaped frame 2041 rotatably installed on the bracket 202. The U-shaped frame 2041 is connected to the driving motor 203 through a coupling. Threaded rods 2042 are installed on both sides of the U-shaped frame 2041. Clamping blocks 2043 are connected to the mutually approaching ends of the two threaded rods 2042. A flexible pad is installed on the clamping block 2043. By screwing the threaded rods 2042, the two clamping blocks 2043 are pushed to press the flexible pad against the luggage case cover for clamping. By the flexible contact between the flexible pad and the luggage case cover, the luggage case cover is prevented from being damaged, and at the same time, the friction force is increased to ensure the stability of clamping.

[0026] Referring to Figure 3, a rotary motor 301 is installed on the frame 1. The output end of the rotary motor 301 is connected to one end of the electric guide rail 302 through a coupling. The electric guide rail 302 is driven by the rotary motor 301 to rotate circumferentially. An electric linear module is formed by the electric guide rail 302 and the electric guide rail 302, and the electric linear module is customized according to the detection requirements.

[0027] Refer to Figure 3 , the three-axis parallel robot 4 includes a stationary platform 401 and a moving platform 402. Three servo motors 403 are annularly distributed on the stationary platform 401. The output ends of the servo motors 403 are all connected with swing arms 404 through couplings. The ends of the swing arms 404 are connected with two pull rods 405 in a ball hinge manner. The pull rods 405 and the moving platform 402 are connected in a ball hinge manner. By rotating the servo motors 403, the rotation of the swing arms 404 is driven to adjust the swinging position of the pull rods 405 and the detection angle and position of the image acquisition device 5.

[0028] Refer to Figure 1 , the image acquisition device 5 is composed of a high-resolution industrial camera, a light source system, an image processing module, a data analysis module and an automatic output module. The high-resolution industrial camera is used to accurately photograph the trunk lid to obtain the image data on the lid surface. The collected images are preprocessed, edge detected and feature extracted by the image processing module to identify the contour and key dimensions of the lid. The extracted features are compared with the preset standard values by the data analysis module, and whether the stamping quality of the lid is qualified is judged by algorithm analysis; according to the data analysis result, a detection report is automatically output.

[0029] The implementation principle of a trunk lid stamping detection device according to an embodiment of the present application is as follows:

[0030] Control the telescopic cylinder 201 to work. The telescopic cylinder 201 expands and contracts according to the size of the trunk lid, adjusts the distance between the two clamps 204, and positions the trunk lid in the middle of the clamps 204. Then turn the threaded rod 2042 to make the clamping block 2043 push the flexible pad to clamp the trunk lid, ensuring that it is stably fixed on the clamp 204. When it is necessary to detect different surfaces of the trunk lid, the drive motor 203 is started again to drive the clamp 204 and the trunk lid to rotate together, realizing the operation of changing the surface of the trunk lid. During the detection process, the rotary motor 301 drives the electric guide rail 302 to rotate in a circle to adjust the position of the electric slider 303 and the three-axis parallel robot 4 thereon in the horizontal direction. Then, combined with the movement of the electric slider 303 along the electric guide rail 302, the position adjustment of the three-axis parallel robot 4 in any radial direction is realized. Then control the servo motor 403 to drive the swing arm 404 and the pull rod 405 to rotate, and adjust the detection angle and position of the image acquisition device 5 according to the detection requirements. Take a precise photo of the trunk lid to obtain the image data on the surface of the lid, and judge whether the stamping quality of the lid is qualified.
