Description

Technical Field

[0001] This utility model relates to the field of plastic product printing technology, specifically to an automatic defect removal robotic arm for plastic product printing. Background Technology

[0002] After color printing is completed, the quality of the printed products needs to be inspected. Currently, this is mostly done by taking images of the printed products with a camera and then comparing them with a standard image of the printed products on a computer. If the difference exceeds the tolerance range, the products are judged as unqualified and need to be removed. Therefore, an automatic defect removal robotic arm is needed.

[0003] The existing patent, CN222491097U, entitled "An Automatic Detection Device for Defects in Color Printed Materials," relates to the field of printed material inspection technology, specifically an automatic detection device for defects in color printed materials. It includes a main body (body 1) with a production line fixedly connected to it. A second body (body 2) is fixedly connected to the side of the production line away from the main body (body 1). A drive motor is fixedly connected to the production line, and a conveyor belt is rotatably connected to the output end of the drive motor. A control panel is fixedly connected to the main body (body 1) and electrically connected to the drive motor. A detection camera is installed between the main body (body 1) and the second body (body 2), and is electrically connected to the control panel. By activating a telescopic cylinder through the control panel, the device drives a feeding plate to push defective printed materials on the conveyor belt towards a collection frame. This allows the device to maintain a good rejection effect when rejecting different types of printed materials, reducing the impact of the material weight of the printed materials on the rejection effect. Therefore, the device can automatically reject various types of printed materials, improving its versatility.

[0004] The aforementioned device has a detection camera installed between body one and body two. The detection camera is electrically connected to the control panel. However, when inspecting products, the products move on the assembly line and their posture and position are not fixed, resulting in poor image acquisition and failing to meet user needs. To address this issue, technological innovation is being carried out based on the existing automatic defect removal robotic arm. Utility Model Content

[0005] The purpose of this invention is to provide an automatic defect removal robotic arm for printing plastic products, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic defect removal robotic arm for printing plastic products, comprising a conveyor belt and a side column. A second conveyor belt is provided on the left side of the first conveyor belt, and the side column is installed on the right side of the first conveyor belt. A lifting rail is installed above the side column. A lifting block is slidably connected inside the lifting rail, and a lead screw is threadedly connected inside the lifting block. A servo motor is installed above the lead screw. The servo motor drives the lead screw to rotate, causing the lifting block to descend in the lifting rail.

[0007] Furthermore, a suspension is installed on the left side of the lifting block, and a sliding rod assembly is installed below the suspension. The suspension extends above the second conveyor belt, facilitating the movement of the product above the second conveyor belt.

[0008] Furthermore, a sliding block is slidably connected to the periphery of the slide bar assembly, and a clamping rail is installed below the sliding block. The clamping blocks move towards each other in the clamping rail to clamp the defective products below.

[0009] Furthermore, the clamping rail is internally slidably connected with a clamping block, and the product is disposed on the inner side below the clamping block. An anti-slip pad is attached to the inner side of the clamping block to prevent the product from falling off.

[0010] Furthermore, the clamping block is internally threaded with a lead screw 2, and a dual-axis motor is installed at one end of the lead screw 2. The dual-axis motor drives the two lead screw 2s with opposite threads to rotate, and the clamping block moves towards each other in the clamping rail to clamp the defective product below.

[0011] Furthermore, an adjustment component is provided above the first conveyor belt, and the adjustment component is connected to the support at the bottom of the first conveyor belt.

[0012] Furthermore, the adjustment assembly includes an adjustment frame, a screw, and a limiting plate. The screw is internally threaded onto the adjustment frame, and one end of the screw is rotatably connected to the limiting plate. The screw moves within the adjustment frame, thereby causing the limiting plate to move above the conveyor belt. The two limiting plates restrict the movement position of the product.

[0013] Furthermore, side frames are installed on the front and rear sides of the side column, and a ball joint is installed at one end of the side frame. A camera is installed on one side of the ball joint. The camera can be rotated and its orientation adjusted by the ball joint. The cameras on the two side frames can collect real-time images of the front and rear printed parts of the product.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotating screw moves in the adjusting frame, thereby driving the limiting plate to move above the first conveyor belt. The two limiting plates restrict the movement position of the product. The camera adjusts its orientation by rotating the ball joint. The cameras on the two side frames collect real-time images of the front and rear printed parts of the product. The servo motor drives the lead screw to rotate, causing the lifting block to descend in the lifting rail. The clamping blocks move towards each other in the clamping rail to clamp the defective product below. The servo motor reverses, driving the product to rise and detach from the first conveyor belt. The clamping rail slides on the slide block group through the moving block. The servo motor lowers the suspension, and the product is placed on the second conveyor belt. The clamping blocks are released, and the defective product is transported to the subsequent processing area through the second conveyor belt.

[0015] 1. After the defective product is identified, the servo motor drives the lead screw to rotate, causing the lifting block to descend in the lifting rail. The dual-axis motor drives the two lead screws with opposite threads to rotate. The clamping blocks move towards each other in the clamping rail to clamp the defective product below. The servo motor reverses, causing the product to rise and detach from the first conveyor belt. The clamping rail slides on the slide bar assembly through the moving block. The suspension extends above the second conveyor belt, facilitating the movement of the product above the second conveyor belt. The servo motor lowers the suspension, and the product is placed on the second conveyor belt. The clamping blocks are released, and the defective product is transported to the subsequent processing area via the second conveyor belt for convenient processing.

[0016] 2. This utility model features a rotating screw that moves within an adjusting frame, thereby causing a limiting plate to move above the conveyor belt. The two limiting plates restrict the movement of the product. The camera adjusts its orientation via a spherical joint. Cameras on the two side frames capture real-time images of the front and rear printed areas of the product. Combined with AI algorithms, this enables rapid identification of defective products, facilitating accurate identification of defective products. Attached Figure Description

A second lead screw 2 is threadedly connected inside the clamping block 13. 14. A dual-axis motor 15 is installed at one end of the lead screw 14. After the defective product is identified, the servo motor 7 drives the lead screw 6 to rotate, causing the lifting block 8 to descend in the lifting rail 5. The dual-axis motor 15 drives the two lead screws 14 with opposite threads to rotate. The clamping block 13 moves towards each other in the clamping rail 12 to clamp the defective product 16 below. The servo motor 7 reverses, causing the product 16 to rise and detach from the conveyor belt 11. The clamping rail 12 slides on the slide block group 10 through the moving block 11. The suspension 9 extends above the conveyor belt 2, facilitating the movement of the product 16 above the conveyor belt 2. The servo motor 7 lowers the suspension 9, and the product 16 is placed on the conveyor belt 2. The clamping block 13 is released, and the defective product is transported to the subsequent processing area via the conveyor belt 2 for convenient processing.

[0022] like Figure 1 and Figure 3 As shown, an adjustment component 3 is provided above the conveyor belt 1, and the adjustment component 3 is connected to the support at the bottom of the conveyor belt 1.

Side frames 17 are installed on the front and rear sides of the side column 4, and a ball joint 18 is installed on one end of the side frame 17. A camera 19 is installed on one side of the ball joint 18. By rotating the screw 302, the screw 302 moves in the adjustment frame 301, thereby driving the limiting plate 303 to move above the conveyor belt 1. The two limiting plates 303 restrict the movement position of the product 16. The camera 19 adjusts its orientation by rotating the ball joint 18. The cameras 19 on the two side frames 17 collect real-time images of the front and rear printed parts of the product 16.

[0023] Working principle: When using the automatic defect removal robot arm for printing plastic products, firstly, the screw 302 is rotated, and the screw 302 moves in the adjusting frame 301, thereby driving the limiting plate 303 to move above the conveyor belt 1. The two limiting plates 303 restrict the movement position of the product 16. The camera 19 rotates and adjusts its orientation through the ball joint 18. The cameras 19 on the two side frames 17 collect real-time images of the front and rear printed parts of the product 16. Combined with AI algorithms, it realizes rapid identification of defective products, which is convenient and accurate.

The servo motor 7 reverses, driving the product 16 to rise and detach from the first conveyor belt 1. The clamping rail 12 slides on the slide bar group 10 through the moving block 11. The suspension 9 extends above the second conveyor belt 2 to facilitate the movement of the product 16 above the second conveyor belt 2. The servo motor 7 lowers the suspension 9, and the product 16 is placed on the second conveyor belt 2. The clamping block 13 is released, and the defective product is transported to the subsequent processing area through the second conveyor belt 2 for convenient processing.
