Description

Technical Field

[0001] This utility model relates to the field of die-cut product inspection, and in particular to a diversion inspection device suitable for multi-hole die-cut products. Background Technology

[0002] Currently, a certain die-cut product has hundreds of small holes, such as Figure 3 As shown, during the die-cutting process, it is impossible to completely remove the die-cutting waste from the small holes, which can easily lead to clogging. This requires personnel to manually inspect each die-cut product. After inspecting more than a certain number of products per day, visual fatigue will occur, which will significantly increase the risk of clogging die-cut products flowing out. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a diversion inspection device suitable for multi-hole die-cut products, so as to save labor and reduce the risk of die-cut products with blocked holes flowing out.

[0004] The technical solution of this utility model is as follows: A sorting and inspection device suitable for multi-hole die-cut products, including: A glass plate, used to support products to be inspected; There are two CCD cameras, one above and one below the glass plate. The two CCD cameras are used to photograph the product to be inspected on the glass plate. The discharge conveyor belt is used to receive and sort the inspected products. A robotic arm is used to move inspected products from a glass plate onto a discharge conveyor belt. The controller receives images captured by two CCD cameras and controls the robotic arm and material conveyor belt based on these images.

[0005] As a preferred embodiment of this invention, it also includes a feeding conveyor belt, which is used to transport the product to be inspected onto the glass plate.

[0006] As a preferred embodiment of this invention, the glass plate is supported by a bracket, and the two CCD cameras and the robotic arm are connected to the bracket.

[0007] To better separate qualified and unqualified products, the discharge conveyor belt is a semi-circular conveyor belt. When the semi-circular conveyor belt moves clockwise, it is used to transport qualified products after inspection, and when it moves counterclockwise, it is used to transport unqualified products after inspection, so that qualified and unqualified products flow in different directions.

[0008] To facilitate the collection of qualified and unqualified products, qualified product receiving boxes and unqualified product receiving boxes are respectively installed at the bottom of both ends of the semi-circular conveyor belt.

[0009] To facilitate the products sliding into different receiving boxes, downward-sloping guide plates are installed at both ends of the semi-circular conveyor belt.

[0010] As a preferred embodiment of this invention, it also includes a photoelectric sensor electrically connected to the controller. The photoelectric sensor is used to detect whether there is a product to be inspected on the glass plate, and the controller controls the two CCD cameras to work based on the output signal of the photoelectric sensor.

[0011] The advantages of this utility model are: A CCD camera is used to inspect multi-hole die-cut products once. Then, a semi-circular conveyor belt is used to separate qualified and unqualified products from the first inspection. NG products (unqualified products) detected in the first inspection are then manually inspected and processed a second time. This significantly reduces the number of manual inspections, saves labor, reduces the labor intensity of workers, and reduces the risk of die-cut products with blocked holes flowing out.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 and Figure 2As shown, this embodiment is a sorting and inspection device suitable for multi-hole die-cut products, including a glass plate 1, two CCD cameras 2, a discharge conveyor belt, a robotic arm 3, and a controller. The glass plate 1 is supported by a bracket 11 and is used to carry the products to be inspected. The two CCD cameras 2 are connected to the bracket 11 and are located above and below the glass plate 1, respectively. The two CCD cameras 2 are used to photograph the products to be inspected carried on the glass plate 1. The discharge conveyor belt can receive the inspected products and sort them. The robotic arm 3 is connected to the bracket 11 and is used to move the inspected products from the glass plate 1 onto the discharge conveyor belt. The way the robotic arm 3 moves the products can avoid the risk of traditional suction-type robotic arms sucking out air bubbles. The controller receives the images captured by the two CCD cameras 2 and controls the operation of the robotic arm 3 and the discharge conveyor belt according to the images.

[0016] This embodiment also includes a feeding conveyor belt 4 and a photoelectric sensor 5 electrically connected to the controller. The feeding conveyor belt 4 is used to transport the product to be inspected to the glass plate 1. The photoelectric sensor 5 is used to detect whether there is a product to be inspected on the glass plate 1. The controller controls the two CCD cameras 2 to work according to the output signal of the photoelectric sensor 5. In this embodiment, the controller adopts a C8051F020 microcontroller and the CCD camera adopts Keyence 3D Vision series products.

[0017] In this embodiment, to better separate qualified and unqualified products, the discharge conveyor belt is a semi-circular conveyor belt 6. When the semi-circular conveyor belt 6 moves clockwise, it is used to transport qualified products after inspection, and when it moves counterclockwise, it is used to transport unqualified products after inspection, so that qualified and unqualified products flow in different directions. In order to facilitate the collection of qualified and unqualified products, this embodiment provides qualified product receiving boxes 7 and unqualified product receiving boxes 8 at the bottom of both ends of the semi-circular conveyor belt 6, respectively. In order to facilitate the products sliding into different receiving boxes, this embodiment provides downward inclined guide plates 9 at both ends of the semi-circular conveyor belt 6, respectively.

[0018] The working process of this embodiment is as follows: The product to be inspected is conveyed to the glass plate 1 by the feeding conveyor belt 4. After the photoelectric sensor 5 detects the product to be inspected on the glass plate 1, it outputs a signal to the controller. The controller controls the two CCD cameras 2 to work. The two CCD cameras 2 respectively capture the upper and lower surfaces of the product to be inspected on the glass plate 1. The images captured by the two CCD cameras 2 are sent to the controller. The controller compares the captured images with preset standard images, and then controls the robotic arm 3 to work based on the image comparison results. The actuator of the robotic arm 3 moves the inspected product from the glass plate 1 to the semi-circular conveyor belt 6. The controller then controls the semi-circular conveyor belt 6 to work. When the product is OK (qualified), the controller controls the semi-circular conveyor belt 6 to move clockwise, and the OK product finally falls into the qualified product receiving box 7. When the product is NG (unqualified), the controller controls the semi-circular conveyor belt 6 to move counterclockwise, and the NG product finally falls into the unqualified product receiving box 8. NG products are subject to secondary inspection and processing by humans, thereby significantly reducing the number of manual inspections, saving labor, reducing the labor intensity of workers, and reducing the risk of die-cut products with blocked holes flowing out.
