Description

Technical Field

[0001] This utility model relates to the field of optical inspection equipment, and in particular to an automated color difference detection device. Background Technology

[0002] In industrial production, the color of some metal exterior components is often directly related to the surface treatment process. However, mass-produced metal exterior components are susceptible to variations due to raw material batches, process parameters, and environmental factors, leading to color deviations between different batches and even within the same batch, thus failing to meet aesthetic requirements. For example, in the consumer electronics field, the metal lens cover of a mobile phone is a protective and auxiliary component covering the camera module, playing a crucial role in protection, optical assistance, and aesthetic decoration. If color deviations occur in the metal lens covers of the same model of mobile phone produced in batches, the color of the lens cover will not match the color of the phone body, failing to guarantee visual consistency and not meeting consumers' demands for a refined look in electronic products.

[0003] Currently, the traditional method for color difference detection of metal exterior components such as metal cover plates for mobile phone lenses is manual visual comparison. Operators place the product to be tested side by side with a standard color swatch and repeatedly compare them to determine whether the product's color matches the standard color swatch. This detection method relies on the operator's visual judgment and experience, which is subject to subjective bias. Moreover, manual inspection is inefficient and cannot meet the needs of testing large-volume products. Therefore, there is an urgent need to provide an automated color difference detection device. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automated color difference detection device with higher detection accuracy and efficiency, which can meet the detection needs of large-volume products.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automated color difference detection device includes a frame and, mounted on the frame, a good product belt conveyor, a defective product belt conveyor, a barcode scanning component, a color difference detection component, a first blocking component, a transfer adsorption component, and a second blocking component. Both the good product belt conveyor and the defective product belt conveyor extend along the Y-axis and are arranged side-by-side. The inlet end of the defective product belt conveyor is aligned with the middle of the good product belt conveyor, and the outlet end is collinearly aligned with the outlet end of the good product belt conveyor. The barcode scanning component is located above the front section of the good product belt conveyor and is used to read the two codes of the products on the good product belt conveyor. The system consists of a QR code scanner and a color difference detection component located behind the QR code scanner. This component detects color differences in products on the good-quality conveyor belt. A first blocking component is located behind the color difference detection component, blocking products on the good-quality conveyor belt that are within the detection area of ​​the color difference detection component. A transfer adsorption component is located behind the first blocking component, picking up products that have failed the color difference detection from the good-quality conveyor belt and transferring them to the defective product conveyor belt. A second blocking component is located behind the transfer adsorption component, blocking products on the good-quality conveyor belt that are within the suction area of ​​the transfer adsorption component.

[0006] Compared with the prior art, this utility model achieves at least the following beneficial effects: Operators feed the products to be inspected onto the feed end of the good-quality belt conveyor. The good-quality belt conveyor automatically transports the products to be inspected, which then pass through a barcode scanning component and a color difference detection component in sequence. The barcode scanning component reads the QR code on the product to be inspected on the good-quality belt conveyor, and the color difference detection component automatically detects the color difference of the product to be inspected. If the product is deemed good, it continues to be transported. If the product is deemed defective, it is picked up by a subsequent transfer and adsorption component and transferred to the defective product belt conveyor. This invention can automatically detect the color difference of metal exterior parts. Compared with manual inspection, it has higher detection accuracy and efficiency, and can meet the inspection needs of large-volume products. Attached Figure Description

[0011] like Figs. 1-7 As shown, the automated color difference detection equipment provided in this application embodiment includes a frame 1 and a good product belt conveyor 2, a defective product belt conveyor 3, a barcode scanning component 4, a color difference detection component 5, a first blocking component 6, a transfer adsorption component 7, and a second blocking component 8, all mounted on the frame 1.

[0012] Both the good product conveyor belt 2 and the defective product conveyor belt 3 extend along the Y-axis and are arranged side by side. The feed end of the defective product conveyor belt 3 is aligned with the middle of the good product conveyor belt 2, and the discharge end is collinearly aligned with the discharge end of the good product conveyor belt 2. Both conveyor belts 2 and 3 consist of a belt support, conveyor belt, rollers, belt support plates, and drive motor. These are existing technologies and will not be described in detail here. Operators feed the product 20 to be inspected onto the feed end of the good product conveyor belt 2. The good product conveyor belt 2 automatically conveys the product 20. After being inspected by the color difference detection component 5, the product 20 is determined to be good and continues conveying; products determined to be defective are transferred to the defective product conveyor belt 3 by the transfer adsorption component 7. The barcode scanning component 4 is located above the front section of the good product conveyor belt 2 and is used to read the QR code on the product 20 on the good product conveyor belt 2. The color difference detection component 5 is located behind the barcode scanning component 4. It is used to detect the color difference of the product 20 on the good product conveyor belt 2 and outputs the real-time detection data to the equipment control system. The equipment control system presets a qualified color difference range and compares the real-time detection data with the preset threshold to determine whether the product 20 is a good or defective product. The first blocking component 6 is located behind the color difference detection component 5. It is used to block the product 20 on the good product conveyor belt 2 that is located in the detection area of ​​the color difference detection component 5, preventing the product 20 in the detection area from continuing to be conveyed, and ensuring that the color difference detection component 5 can successfully complete the detection of the product 20. The transfer adsorption component 7 is located behind the first blocking component 6. After the color difference detection component 5 detects the product 20, when it is determined to be a defective product, the control system sends positioning coordinates and pick-up / placement instructions to the transfer adsorption component 7. The transfer adsorption component 7 moves to the position of the defective product 20 according to the preset path, picks up the defective product 20, and transfers it to the defective product conveyor belt 3. The second blocking component 8 is located behind the transfer adsorption component 7. It is used to block the product 20 on the good product belt conveyor 2 that is located in the suction area of ​​the transfer adsorption component 7, to prevent the product 20 in the suction area from continuing to be conveyed backward, and to ensure that the transfer adsorption component 7 can successfully complete the suction action of the product 20.

[0013] In this embodiment, the barcode scanning component 4 includes a barcode scanner bracket 41 and a barcode scanner 42. The barcode scanner bracket 41 is vertically fixed to the frame 1 and located above the front section of the good-quality product belt conveyor 2. The barcode scanner 42 is mounted on the barcode scanner bracket 41. The metal appearance component product 20 is pre-marked with a QR code using processes such as laser engraving. The working surface of the barcode scanner 42 faces the conveyor belt on the good-quality product belt conveyor 2. Before the product 20 enters the color difference detection station, the barcode scanner 42 quickly reads the QR code. The QR code contains information such as the model and production batch of the metal appearance component product 20, completing the binding of the product 20's identity with the detection system and ensuring that the color difference detection standard accurately matches the product 20's model. This application does not limit the model of the barcode scanner 42.

The slide 532 is slidably connected to the dovetail guide rail 5311. The adjustment knob 533 is connected to the slide 532. Rotating the adjustment knob 533 drives the slide 532 to move up and down along the Z-axis on the dovetail guide rail 5311, thereby adjusting the vertical position of the slide 532 and the colorimeter 54. The manual dovetail precision slide 53 is prior art and will not be described in detail here.

[0017] Furthermore, the connecting frame 75 includes two Y-axis connecting plates 751 arranged side by side and two X-axis connecting plates 752 arranged side by side.

Both Y-axis connecting plates 751 are provided with a first oblong hole 7511 along the length direction. Both X-axis connecting plates 752 are provided with a second oblong hole 7521 along the length direction. A connecting screw hole 7522 adapted to the first oblong hole 7511 is also provided. A screw threadedly connected to the connecting screw hole 7522 passes through the first oblong hole 7511. Four vacuum suction cups 76 are provided. Two vacuum suction cups 76 are installed on the second oblong hole 7521 of one X-axis connecting plate 752, and the other two vacuum suction cups 76 are installed on the second oblong hole 7521 of another X-axis connecting plate 752. Because of the first oblong hole 7511, the distance between the two X-axis connecting plates 752 can be flexibly adjusted by loosening the screws that are threaded to the connecting screw hole 7522. Because of the second oblong hole 7521, the position of the vacuum suction cup 76 on the two X-axis connecting plates 752 can be flexibly adjusted, so that the vacuum suction cup 76 can adapt to the size of the product 20.

[0018] Furthermore, the vacuum suction cup 76 includes a suction cup hardware bracket 761 and a suction cup body 762 installed at the lower end of the suction cup hardware bracket 761.

The upper end of the suction cup hardware bracket 761 is provided with an air pipe connector.

[0019] In this embodiment, the second blocking component 8 includes a gantry bracket 81, a third Z-axis cylinder 82, and a second stop 83.

The second stop 83 is horizontally arranged and fixedly connected to the piston rod output end of the third Z-axis cylinder 82. The third Z-axis cylinder 82 is used to drive the second stop 83 to move up and down along the Z-axis direction. The second stop 83 is used to block the product 20 located behind the material suction area of ​​the transfer adsorption component 7.

[0020] In this embodiment, the discharge ends of the good product belt conveyor 2 and the defective product belt conveyor 3 are respectively provided with a first baffle 21 and a second baffle 31. The first baffle 21 and the second baffle 31 are respectively used to block the product 20 at the discharge ends of the good product belt conveyor 2 and the defective product belt conveyor 3.

[0021] In this embodiment, a first displacement sensor 9 is installed on one side of the color difference detection component 5 on the good product belt conveyor 2, and a second displacement sensor 10 is installed on one side of the transfer adsorption component 7. The first displacement sensor 9 is used to determine whether the product 20 enters the detection area of ​​the color difference detection component 5, and the second displacement sensor 10 is used to determine whether the product 20 enters the suction area of ​​the transfer adsorption component 7. On the good-quality belt conveyor 2, due to the height difference between the product 20 and the belt surface, the first displacement sensor 9 and the second displacement sensor 10 are fixedly installed on the side of the good-quality belt conveyor 2 to continuously measure the distance from the sensor to the measured surface (belt surface). When there is no product 20, the distance measured by the first displacement sensor 9 and the second displacement sensor 10 is a fixed value H0 from the sensor to the belt surface. When there is a product 20, the distance measured by the first displacement sensor 9 and the second displacement sensor 10 is the distance H1 from the sensor to the surface of the product 20. Since the product 20 has a height, H1 < H0. The first displacement sensor 9 and the second displacement sensor 10 convert the distance signal into an analog quantity and output it to the equipment control system. The control system recognizes the signal jump from H0 to H1, determines that the product 20 has entered the sensor detection area, and controls the corresponding color difference detection component 5 and transfer adsorption component 7 to work.

[0022] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
