Description

Technical Field

[0001] The invention belongs to the technical field of die-cut product inspection tables, and specifically relates to an automatic die-cut product inspection table and a use method thereof. Background Art

[0002] The die-cut product inspection bench is mainly used for quality control and inspection of die-cut products to ensure that the products meet the design requirements and standards. Die-cutting is a process of cutting materials (such as paper, plastic, and metal, etc.) into specific shapes through a die. During the die-cutting process, the material is pressed onto the die in the die-cutting machine and cut by a cutter to form the desired shape. Due to the high requirements for size, shape and quality of die-cut products, strict inspection of die-cut products is required during the production process. Inspection contents include dimensional measurement, appearance inspection, edge processing, etc. Die-cut products have a wide range of applications, including food packaging, electronic product housings, advertising materials, etc. Therefore, the importance of inspection benches in various industries is becoming increasingly prominent.

[0003] Existing die-cut product inspection stations are generally equipped with a variety of inspection tools and equipment, and use manual visual inspection to inspect die-cut products. Workers use inspection tools to measure the size and appearance of die-cut products. However, manual inspection not only consumes a lot of manpower, but also damages the workers' eyes and spirit because they need to concentrate on visually inspecting die-cut products for a long time. In addition, manual inspection is prone to errors. Therefore, it is necessary to design a more automated die-cut product inspection station. Summary of the invention

[0004] Based on the technical problems mentioned in the background technology, the present invention proposes an automatic inspection table for die-cut products and a method for using the same.

[0005] The present invention adopts the following technical solutions: An automatic inspection platform for die-cut products includes a detection platform body, a die-cut product unloading structure and a unloading servo motor are arranged on the left side of the detection platform body, and a die-cut product receiving structure and a receiving servo motor are arranged on the right side of the detection platform body. One end of the die-cut product is rolled on the die-cut product unloading structure, and the other end is rolled on the die-cut product receiving structure. The unloading servo motor is connected to the die-cut product unloading structure by transmission, and the receiving servo motor is connected to the die-cut product receiving structure by transmission. The unloading servo motor and the receiving servo motor drive the die-cut product unloading structure and the die-cut product receiving structure to rotate respectively, so that the die-cut product starts from the die-cut product unloading structure. After passing through the upper surface of the detection table, it reaches the die-cutting product receiving structure. A driving device is installed in the detection table, and the driving device is connected to at least one visual acquisition unit. The visual acquisition unit is used to collect the visual image of the die-cutting product on the upper surface of the detection table. The driving device is used to drive the visual acquisition unit to move, so that the visual acquisition unit can collect different positions on the upper surface of the detection table. A detection controller is installed in the detection table, and the detection controller is connected to the visual acquisition unit and the driving device. The detection controller can receive and analyze the visual image transmitted by the visual acquisition unit, and the detection controller can control the operation of the driving device.

[0006] To optimize the technical solution, further measures are taken: A fill light unit is arranged above the above-mentioned detection platform, and the fill light unit is used to increase the intensity of light irradiated on the surface of the die-cut product.

[0007] A plurality of passive coil guide rollers are arranged on the left and right sides of the above-mentioned detection platform, and the die-cut products are wound around the passive coil guide rollers.

[0008] The above-mentioned die-cut product unloading structure includes a unloading structure shell and a unloading wheel, a rotatable first unloading wheel and a second unloading wheel are installed in the unloading structure shell, a first belt is wound around the first unloading wheel and the second unloading wheel, a rotating shaft of the unloading servo motor is fixedly connected to the axle of the first unloading wheel, axle of the unloading wheel is fixedly connected to the axle of the second unloading wheel, and one end of the die-cut product is rolled on the unloading wheel.

[0009] The above-mentioned die-cut product receiving structure includes a receiving structure shell and a receiving wheel, a rotatable first receiving wheel and a second receiving wheel are installed in the receiving structure shell, a second belt is wound around the first receiving wheel and the second receiving wheel, a rotating shaft of the receiving servo motor is fixedly connected to the axle of the first receiving wheel, axle of the receiving wheel is fixedly connected to the axle of the second receiving wheel, and the other end of the die-cut product is rolled on the receiving wheel.

[0010] The above-mentioned driving device includes a driving motor, a slide rail, a slide seat and a lead screw. The slide rail runs left and right, and is fixedly installed in the detection platform body. The slide seat is slidably installed on the slide rail. The lead screw runs forward and backward, and the slide seat is sleeved on the lead screw. The motor shaft of the driving motor is fixedly connected to the lead screw. When the motor drives the lead screw to rotate, the lead screw can drive the slide seat to slide on the slide rail, and the visual acquisition unit is fixedly installed on the slide seat.

[0011] The above-mentioned detection platform is provided with an opening extending left and right, the slide is connected to the visual collection unit through a connecting rod, the slide is located inside the detection platform, the visual collection unit is located outside the detection platform, and the connecting rod passes through the opening.

[0012] A travel limit block is respectively arranged at the left and right ends of the above-mentioned slide rail, and the travel limit block is connected with the drive motor signal. When the slide seat touches the travel limit block, the drive motor stops operating.

[0013] A display is arranged on the detection platform, and the display is connected with the detection controller signal. The detection controller can amplify the visual image transmitted by the visual acquisition unit and display it on the display.

[0014] A method for using an automatic die-cutting product inspection table, using the automatic die-cutting product inspection table, comprises the following steps: Step 1: Prepare a comparison library of multiple qualified die-cut product images and unqualified die-cut product images in advance and store them in the detection controller. Roll the two ends of the die-cut product to be detected on the unwinding wheel and the receiving wheel respectively. After the die-cut product passes through the passive guide roller of the coil, it passes through the upper surface of the detection table. Step 2: Start the supplementary light unit to ensure that the die-cut products on the upper surface of the inspection platform are adequately illuminated; Step 3: Start the drive motor, which drives the slide to slide rightward on the slide rail. The visual acquisition unit acquires the visual image of the die-cut product on the upper surface of the detection platform from left to right. The slide stops moving when it touches the travel limit block at the right end of the slide rail. The visual acquisition unit sends the visual image to the detection controller. The detection controller compares the visual image with the image in the comparison library to find the comparison library image that is closest to the visual image. Then, the comparison library image is used to determine whether the die-cut product is qualified or unqualified according to whether the comparison library image is a qualified die-cut product image or an unqualified die-cut product image. Step 4: Start the unloading servo motor and the receiving servo motor to move the die-cut products. When the die-cut products on the upper surface of the collection and detection table are completely replaced with new ones, the unloading servo motor and the receiving servo motor stop moving. Step 5. Start the drive motor, which drives the slide to slide to the left on the slide rail. The visual acquisition unit acquires the visual image of the die-cut product on the upper surface of the detection table from right to left. The slide stops moving when it touches the travel limit block at the left end of the slide rail. The visual acquisition unit sends the visual image to the detection controller, which determines whether the die-cut product is qualified in the same way as in step 3, and then starts the unloading servo motor and the receiving servo motor to move the die-cut product. When the die-cut product on the upper surface of the detection table is completely replaced with a new one, the unloading servo motor and the receiving servo motor stop moving. Step 6. Repeat steps 3 to 5 until all die-cut products on the unwinding wheel are transferred to the receiving wheel.

The detection controller is used to control the operation of the driving device and analyze the visual image transmitted by the visual acquisition unit, so that the detection and analysis work is completely responsible for the detection controller, which can greatly reduce labor consumption, and has a high degree of automation and high accuracy.

[0016] The detection controller of the present invention adopts a visual comparison method to determine whether the die-cut product is qualified. Specifically, a plurality of qualified die-cut product pictures and unqualified die-cut product pictures are made into a comparison library in advance and stored in the detection controller. The detection controller compares the visual image with the picture in the comparison library, finds the comparison library picture closest to the visual image, and then determines whether the die-cut product is qualified according to whether the comparison library picture belongs to a qualified die-cut product picture or an unqualified die-cut product picture. This comparison method is fast and has high accuracy. The detection controller can display the visual image of the unqualified die-cut product on the display. Workers only need to perform manual analysis on the unqualified die-cut products without having to stare at the test bench all the time, which can greatly reduce the workers' eyesight and mental loss.
