Description

Technical Field

[0001] This utility model relates to the field of visual inspection device technology, and more specifically, to a multi-faceted inverted visual inspection device. Background Technology

[0002] A visual inspection device is an automated inspection device that simulates the function of the human eye using machine vision technology. For example, application number "CN202010880798.9" proposes a machine vision-based weld surface inspection device, comprising: an inspection conveyor, a first gantry, a second gantry, a first light source, an image acquisition unit, and a controller. The first light source and the image acquisition unit are connected to the controller. The first and second gantry span the inspection conveyor. The first light source is mounted on the first gantry, and the image acquisition unit is mounted on the second gantry for acquiring real-time images of the welded object and transmitting these images to the controller. The controller compares the weld surface in the real-time image with the weld surface in a standard image to determine whether the weld surface of the corresponding welded object in the real-time image is qualified. If it is unqualified, an alarm is issued.

[0003] However, the above technical solutions can only inspect a specific side of the welded object and cannot comprehensively inspect multiple sides of the material. In actual production, many product quality problems may occur on different surfaces, and it is difficult to ensure comprehensive control of product quality by only inspecting one side. Therefore, we propose a multi-faceted reverse vision inspection device to solve the above problems. Utility Model Content

The limit frames 6 are movably located at the upper end of the conveyor belt 2, and are relatively parallel to each other. Second cylinders 7 are installed on the front and rear sides of one end of the upper surface of the support platform 1, respectively. The output end of the second cylinder 7 is connected to the limit frame 6. A first guide rod 406 is fixedly installed inside the groove 405 and at the end near the limit frame 6. The rod body of the first guide rod 406 is movably installed through the inside of the clamping frame 409. A second cylinder 7 is movably installed through the inside of the groove 405 and at the end away from the limit frame 6. A forward and reverse lead screw 407 is threadedly installed inside a clamping frame 409. A second motor 408 is installed on the rear side of a connecting block 404, and the output end of the second motor 408 is connected to the forward and reverse lead screw 407. The lower end of the clamping frame 409 has a transmission groove 412. A first rotating shaft 411 is movably installed through the upper end of each transmission groove 412. A second rotating shaft 415 is movably installed through the inner, adjacent ends of each transmission groove 412. The adjacent ends of the second rotating shafts 415 are connected to a clamping plate 410. The first rotating shaft 41... A first helical gear 413 is installed at one end of the transmission groove 412, and a second helical gear 414 is installed at one end of the second rotating shaft 415 inside the transmission groove 412.

[0029] The user first controls the movement of the limiting frame 6 using the second cylinder 7 to adjust the spacing according to the size of the material. After adjustment, the user places the material on the surface of the conveyor belt 2, allowing the conveyor belt 2 to move the material. The limiting frame 6 guides the material, keeping it in the center. The first image acquisition device 5 then begins to capture images of the material's upper surface and front and rear sides. When the material moves to the lower end of the support frame 401, the first cylinder 402 pushes the first motor 403 and connecting block 404 downwards. The connecting block 404 then moves the clamping frame 409 to the front and rear ends of the material. The second motor 408 then drives the positive and negative lead screws 407 to rotate, causing the lead screws 407 to control the movement of the clamping frame 409 via the thread. The clamping frame 409 then moves the clamping plate 410 to clamp the front and rear sides of the material. After the material is clamped, the first cylinder 402 controls the clamping frame 409 to move upwards, temporarily separating the material from the conveyor belt 2. Then, the first motor 403 drives the connecting block 404 to rotate 90°, changing the front and back sides of the material into the left and right sides, and the original left and right sides into the front and back sides. Simultaneously, as the connecting block 404 rotates, the gear 416 first slides along the arc-shaped guide frame 417. Then, when the connecting block 404 rotates nearly 90°, the gear 416 meshes with the teeth 418, allowing the gear 416 to rotate through the teeth 418. The gear 416 then drives the first rotating shaft 411 to rotate. Then, the first rotating shaft 411 can drive the second rotating shaft 415 through the first helical gear 413 and the second helical gear 414. The second rotating shaft 415 can then drive the clamping plate 410 and the material to rotate, so that the lower surface of the material is rotated to the upper side. After the material is reversed, the first cylinder 402 can put the material back on the surface of the conveyor belt 2, so that the conveyor belt 2 can move the material. Then, the image acquisition device 5 can detect the material after it is reversed, so as to realize the all-round detection of the material.

[0030] The working principle of this multi-faceted inverted visual inspection device:

[0031] In use, the user first controls the movement of the limiting frame 6 using the second cylinder 7 to adjust the spacing according to the size of the material. After adjustment, the user places the material on the surface of the conveyor belt 2, allowing the conveyor belt 2 to move the material. The limiting frame 6 guides the material, keeping it in the center. The first image acquisition device 5 then begins to capture images of the material's upper surface and front and rear sides. When the material moves to the lower end of the support frame 401, the first cylinder 402 pushes the first motor 403 and connecting block 404 downwards. The connecting block 404 then moves the clamping frame 409 to the front and rear ends of the material. The second motor 408 then drives the positive and negative lead screws 407 to rotate, causing the lead screws 407 to control the movement of the clamping frame 409 via the thread. The clamping frame 409 then moves the clamping plate 410 to clamp the front and rear sides of the material. After the material is clamped, the first cylinder 402 controls the clamping frame 409 and the material to move upwards, temporarily keeping the material in contact with the conveyor belt 2. After separation, the first motor 403 drives the connecting block 404 to rotate 90°, changing the front and back sides of the material into the left and right sides, and the original left and right sides into the front and back sides. Simultaneously, as the connecting block 404 rotates, the gear 416 first slides along the arc-shaped guide frame 417. Then, when the connecting block 404 rotates nearly 90°, the gear 416 meshes with the teeth 418, allowing the gear 416 to rotate through the teeth 418. The gear 416 then drives the first rotating shaft 411 to rotate. The first rotating shaft 411 then drives the second rotating shaft 415 through the first helical gear 413 and the second helical gear 414. The second rotating shaft 415 then drives the clamping plate 410 and the material to rotate, so that the lower surface of the material is rotated to the upper side. After the material is reversed, the first cylinder 402 can place the material back on the surface of the conveyor belt 2, so that the conveyor belt 2 can move the material. Then, the image acquisition device 5 will detect the material after it is reversed, so as to realize the all-round detection of the material.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
