A pair of racks 9 are both meshed and connected to the gear 12. The driving assembly 7 includes a second servo motor 71 and a rotating rod 72. The rotating rod 72 is rotatably connected to the top of the base 6. The second servo motor 71 is installed on the base 6, and the output end of the second servo motor 71 is fixedly connected to the rotating rod 72. A pair of first pulleys 73 are fixedly connected to the outer end of the rotating rod 72, and a belt 74 is installed at the outer end of the first pulley 73. The outer ends of the pair of rotating wheels 8 are both fixedly connected to the second pulley 13, and the second pulley 13 is transmission-connected to the first pulley 73 through the belt 74.

[0028] In plastic injection molding production, appearance quality is usually an important indicator. The existing technology generally performs appearance inspection on injection molded products through an appearance inspection line. For some products or specific appearance defects, it may be necessary to flip the product in order to comprehensively inspect all parts of the product. The flipping mechanism on the existing inspection line is mostly a robotic arm. The robotic arm can be controlled in a programmed manner to flip the product by grasping. However, the robotic arm has the problem of high cost, and for products of different sizes, the grasping program of the robotic arm needs to be re-debugged, which brings inconvenience to use.

[0029] In this solution, the product 4 is sequentially transported through the first conveyor belt 1, the transfer conveyor belt 3, and the second conveyor belt 2. A camera for detecting surface quality is installed on the inner side of a pair of detection gates 5. When the product 4 is transported on the first conveyor belt 1, it will pass through the inner side of one of the detection gates 5. The camera inside the detection gate 5 will take a picture of one surface of the product 4 and upload it. The computer will inspect the picture to determine whether it is qualified. When the product 4 is transported on the second conveyor belt 2, it will pass through the inner side of the other detection gate 5, and the camera inside the detection gate 5 will take another surface of the product 4. The product 4 is flipped on the transfer conveyor belt 3. The specific process is as follows: when the product 4 comes from the first conveyor belt 1 to the transfer conveyor belt 3, the transfer conveyor belt 3 will temporarily stop running. The width of the transfer conveyor belt 3 is smaller than the first conveyor belt 1 and the second conveyor belt 2. Therefore, when the product 4 stays on the transfer conveyor belt 3, the two ends of the product 4 extend out of the edge position of the transfer conveyor belt 3. A pair of clamping plates 10 located on the lower side will be on the lower side of the two ends of the product 4. At this time, the user starts a pair of first servo motors 11 to run synchronously, thereby driving a pair of gears 12 to rotate synchronously. The rotation of the gear 12 will drive a pair of racks 9 to slide on the rotating wheel 8, and then drive a pair of clamping plates 10 to move in a direction close to each other. The clamping plate 10 located on the lower side will lift the product 4 to make the product 4 separate from the transfer conveyor belt 3 until the pair of clamping plates 10 clamp the product 4. At this time, the user starts the second servo motor 71 to drive the rotating rod 72 to rotate, and the rotating rod 72 drives a pair of first pulleys 73 to rotate, and then drives a pair of second pulleys 13 to rotate through the belt 74, thereby driving the rotating wheel 8 to rotate 180°. Since the first servo motor 11 is installed on the rotating wheel 8, the rotating rod 72 drives a pair of first pulleys 73 to rotate, and then drives a pair of second pulleys 13 to rotate through the belt 74, thereby driving the rotating wheel 8 to rotate 180°. On the moving wheel 8, the first servo motor 11 and the gear 12 will rotate with the rotating wheel 8, thereby driving a pair of racks 9 and a pair of clamping plates 10 to rotate, thereby forcing the product 4 to rotate 180° to achieve flipping. After the flipping is completed, the user starts the pair of first servo motors 11 again to drive the pair of gears 12 to rotate in the opposite direction, thereby forcing the pair of clamping plates 10 to move away from each other. At this time, the clamping plate 10 on the lower side will carry the product 4 back to the transfer conveyor belt 3, and then the user starts the transfer conveyor belt 3 again to transport the flipped transfer conveyor belt 3 to the second conveyor belt 2.

[0030] The upper surfaces of the first conveyor belt 1, the second conveyor belt 2 and the transfer conveyor belt 3 are all arranged at the same horizontal position.

[0031] In this solution, the upper surfaces of the first conveyor belt 1 , the second conveyor belt 2 and the transfer conveyor belt 3 are all arranged at the same horizontal position, so that the product 4 can be stably transmitted between the first conveyor belt 1 , the second conveyor belt 2 and the transfer conveyor belt 3 .

[0032] The upper surface of the clamping plate 10 located at the lower side is lower than the upper surface of the transfer conveyor belt 3 .

[0033] In this solution, the upper surface of the clamping plate 10 located on the lower side is lower than the upper surface of the transfer conveyor belt 3. This arrangement can ensure that after the product 4 reaches the upper end of the transfer conveyor belt 3, a pair of clamping plates 10 located on the lower side can be exactly on both sides of the lower end of the product 4, ensuring that the pair of clamping plates 10 can smoothly lift the product 4.

[0034] A rubber pad is installed on one end of a pair of clamping plates 10 close to each other.

[0035] In this solution, the rubber pad installed on the clamping plate 10 can enhance the friction between the clamping plate 10 and the product 4, thereby improving the stability of the clamping plate 10 clamping the product 4 and preventing the product 4 from falling off during the flipping process.

[0036] like Figure 5 As shown, a slide groove 14 is provided at the outer end of the rack 9, a slider is fixedly connected to one end of the clamping plate 10, the slider is slidably connected to the slide groove 14, a spring 15 is provided inside the slide groove 14, and both ends of the spring 15 are fixedly connected to the inner wall of the slide groove 14 and the slider respectively.

[0037] After the pair of clamping plates 10 clamp the product 4, the pair of racks 9 can continue to move towards each other. At this time, the pair of clamping plates 10 will slide in the slide groove 14 through the slider and stretch the spring 15. This arrangement can improve the applicability of the device. When the number of rotations of the gear 12 remains unchanged, the pair of clamping plates 10 can stably clamp products 4 of various sizes.

[0038] Working principle:

[0039] The product 4 is sequentially transmitted through the first conveyor belt 1, the transfer conveyor belt 3 and the second conveyor belt 2. When the product 4 is transmitted on the first conveyor belt 1, it will pass through the inside of one of the inspection gates 5. The camera inside the inspection gate 5 will take a picture of a surface of the product 4 and upload it. The computer will detect the picture to determine whether it is qualified. When the product 4 comes from the first conveyor belt 1 to the transfer conveyor belt 3, the transfer conveyor belt 3 will temporarily stop running. At this time, the user starts a pair of first servo motors 11 to run synchronously, thereby driving a pair of gears 12 to rotate synchronously. The rotation of the gears 12 will drive a pair of racks 9 to slide on the rotating wheel 8, thereby driving a pair of clamping plates 10 to move in a direction close to each other. The clamping plate 10 on the lower side will lift the product 4 to make the product 4 leave the transfer conveyor belt 3 until the pair of clamping plates 10 clamp the product 4. At this time, the user starts the second servo motor 71 drives the rotating rod 72 to rotate, the rotating rod 72 drives a pair of first pulleys 73 to rotate, and then drives a pair of second pulleys 13 to rotate through the belt 74, thereby driving the rotating wheel 8 to rotate 180°, and the rotating wheel 8 drives a pair of racks 9 and a pair of clamping plates 10 to rotate, thereby forcing the product 4 to rotate 180° to achieve flipping. After the flipping is completed, the user starts the pair of first servo motors 11 again to drive the pair of gears 12 to rotate in the opposite direction, thereby forcing the pair of clamping plates 10 to move away from each other. At this time, the clamping plate 10 on the lower side will carry the product 4 back to the transfer conveyor belt 3, and then the user starts the transfer conveyor belt 3 again to transport the flipped transfer conveyor belt 3 to the second conveyor belt 2. When the product 4 is transmitted on the second conveyor belt 2, it will pass through the inside of another detection gate 5, and the camera inside the detection gate 5 will take a picture of the other surface of the product 4.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
