[0025] Embodiment 1

[0026] A high-precision vision detection device, as Figures 1-4 shown, includes a protective box 1. The outer walls on both sides of the protective box 1 are fixed with a top cover 10. A group of sliding plates 6 are respectively slidably connected to the outer walls on both sides of the top cover 10. The outer walls of the sliding plates 6 are fixed with a rack plate 7 and a sealing door 5. A group of motors 9 are fixed to the outer wall of the top of the top cover 10. The output shaft of the motor 9 is fixed with a gear 8. The gear 8 is meshed with the rack plate 7. A shooting mechanism is arranged on the outer wall of the top of the protective box 1. A conveyor belt 3 is arranged on the inner wall of the bottom of the protective box 1; a control panel 11 is fixed to the outer wall of one side of the protective box 1. The conveyor belt 3 and the motor 9 are respectively electrically connected to the control panel 11.

[0027] The staff sequentially place the products to be detected on the conveyor belt 3, and then control the conveyor belt 3 to drive the products forward through the control panel 11. When the products move into the protective box 1, the control panel 11 controls the conveyor belt 3 to stop running, and at the same time controls the motor 9 to drive the gear 8 to rotate in the corresponding direction, so as to drive the two sealing doors 5 to move relatively through the rotating gear 8 until the two sealing doors 5 are attached to each other, thereby shielding the surroundings of the products through the protective box 1 and the sealing doors 5, avoiding the influence of the surrounding environment and light of the detection device on the vision detection of the products by the shooting mechanism, and improving the accuracy of vision detection;

[0028] After the visual inspection is completed, the control panel 11 controls the conveyor belt 3 to run again. At the same time, it controls the corresponding motor 9 to drive the gear 8 to rotate in the reverse direction for the corresponding number of turns, opens the sealing doors 5 on both sides of the protective box 1, allows the inspected products to be conveyed out through the conveyor belt 3, and at the same time moves the new products into the protective box 1 through the conveyor belt 3, so as to continue the inspection of subsequent products.

[0029] As Figures 2-3 shown, the photographing mechanism includes a first electric slide rail 16, a movable block 15, an electric telescopic rod 13, and a camera 19. The first electric slide rail 16 is slidably connected to the top outer wall of the protective box 1. The movable block 15 is slidably connected to the inner wall of the first electric slide rail 16. The electric telescopic rod 13 is fixed to the outer wall of one side of the movable block 15. The camera 19 is fixed to the output shaft of the electric telescopic rod 13. The camera 19, the electric telescopic rod 13, and the first electric slide rail 16 are respectively electrically connected to the control panel 11. The control panel 11 can drive the camera 19 to move up, down, left, and right by controlling the first electric slide rail 16 and the electric telescopic rod 13, so that the camera 19 can perform visual inspection on the product surface from different angles.

[0030] As Figure 2 shown, a second electric slide rail 18 and a guide plate 12 are fixed to the top outer wall of the protective box 1. The first electric slide rail 16 is slidably connected to the second electric slide rail 18 and the guide plate 12. The second electric slide rail 18 is electrically connected to the control panel 11. The control panel 11 can drive the first electric slide rail 16 to move back and forth as a whole by controlling the second electric slide rail 18, thereby driving the camera 19 to move back and forth as a whole, and cooperating with the first electric slide rail 16 and the electric telescopic rod 13 to flexibly adjust the position of the camera 19.

[0031] As Figure 3 shown, a slide plate 14 is fixed to the outer wall of the electric telescopic rod 13. The slide plate 14 is slidably connected to the bottom outer wall of the top cover 10. When the second electric slide rail 18 and the first electric slide rail 16 drive the electric telescopic rod 13 to move back and forth, left and right inside the protective box 1, the slide plate 14 located on the outer wall of the electric telescopic rod 13 will also slide on the bottom outer wall of the top cover 10, thereby guiding the moving electric telescopic rod 13 and improving the stability of the electric telescopic rod 13 during movement.

[0032] As Figure 2 shown, an infrared detection radar 17 is fixed to one inner wall of the protective box 1. The infrared detection radar 17 is electrically connected to the control panel 11. When the product moves into the protective box 1 driven by the conveyor belt 3, the infrared detection radar 17 on the inner wall of the protective box 1 will sense the approach of the product, and thus send an electrical signal to the control panel 11, enabling the control panel 11 to promptly control the conveyor belt 3 to stop running and at the same time promptly control the motor 9 to run to drive the sealing door 5 to close.

[0033] As shown Figure 3 in the figure, a lighting lamp 20 is fixedly installed on the outer wall of the bottom of the movable block 15, and the lighting lamp 20 is electrically connected to the control panel 11. The control panel 11 can control the lighting lamp 20 to be turned on to illuminate the product, thereby improving the detection accuracy of the surface details of the product by the camera 19.

[0034] Working principle: The staff sequentially place the products to be detected on the conveyor belt 3, and then control the conveyor belt 3 to drive the products forward through the control panel 11. When the products move into the protection box 1, the control panel 11 controls the conveyor belt 3 to stop running, and at the same time controls the motor 9 to drive the gear 8 to rotate in the corresponding direction, so that the two sealing doors 5 are driven to move relatively by the rotating gear 8 until the two sealing doors 5 are attached together, thereby shielding the surroundings of the product through the protection box 1 and the sealing doors 5, and avoiding the influence of the surrounding environment and light of the detection device on the visual detection of the product by the shooting mechanism.

[0035] After the visual detection is completed, the control panel 11 controls the conveyor belt 3 to run again, and at the same time controls the corresponding motor 9 to drive the gear 8 to rotate in the reverse direction for the corresponding number of turns, opens the sealing doors 5 blocking both sides of the protection box 1, allows the detected products to be conveyed out through the conveyor belt 3, and at the same time moves the new products into the protection box 1 through the conveyor belt 3, so as to continue to detect the subsequent products.
