Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, specifically to an automatic PCB identification and error prevention device. Background Technology

[0002] PCB, short for Printed Circuit Board, is an indispensable and crucial component of electronic devices. It primarily supports and connects various electronic components, such as resistors, capacitors, transistors, and integrated circuits, linking them together through conductive paths to form complete circuits. PCB design and manufacturing involve multiple fields, including electronic engineering, materials science, and computer-aided design (CAD). Automatic PCB identification and error-proofing devices are quality control equipment used in the electronic manufacturing process. Their main purpose is to automatically detect errors or defects on the PCB during production to ensure the quality and reliability of the final product.

[0003] In existing technologies, automatic PCB identification and error prevention usually requires visual inspection of the PCB surface and scanning of QR codes on the PCB surface to facilitate refined management and traceability. However, the existing technologies mostly involve multiple steps in the above operations. Such identification methods have low efficiency due to their continuous identification, which may lead to a decrease in identification efficiency and cannot complete the automatic loading and unloading process. Therefore, we propose an automatic PCB identification and error prevention device. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3This utility model provides a technical solution: an automatic PCB identification and error prevention device, including a work frame 1, a feeding frame 6 and a discharging frame 7 are provided through the work frame 1, a feeding mechanism 9 and a discharging mechanism 10 are fixedly installed at the bottom of the work frame 1 and at the positions corresponding to the feeding frame 6 and the discharging frame 7, respectively, a bearing detection frame 8 is provided at the top of the work frame 1, a barcode detection mechanism 4 for detecting barcodes on the PCB board is provided at the top of the work frame 1 and at the position corresponding to the barcode detection mechanism 4, a visual inspection mechanism 5 for visual inspection of the PCB board is provided at the top of the work frame 1 and at the position corresponding to the discharging frame 7, and a telescopic mechanism 2 for moving the PCB board up and down is provided on the work frame 1, and a picking mechanism 3 for rotating the PCB board is fixedly installed on the telescopic mechanism 2.

[0018] The feeding frame 6, unloading frame 7, and load-bearing detection frame 8 can continuously identify and detect the PCB at different positions. The feeding mechanism 9 and unloading mechanism 10 can realize the automatic feeding and receiving process of the PCB. The telescopic mechanism 2 and the picking mechanism 3 work together to make the PCB move back and forth along the feeding frame 6, unloading frame 7, and load-bearing detection frame 8. Thus, the barcode detection mechanism 4 and the vision inspection mechanism 5 can quickly detect the PCB. This automatic identification and error prevention has a high degree of automation and improves the processing efficiency to a certain extent.

[0019] Please see Figure 1 and Figure 2 The telescopic mechanism 2 includes a fixed plate 11, a hollow tube 12, a telescopic rod 13, a telescopic plate 14, and a drive cylinder 16. The fixed plate 11 is fixedly installed on the working frame 1. Multiple sets of hollow tubes 12 are fixedly installed on the top of the fixed plate 11. The telescopic rod 13 is slidably connected inside the hollow tube 12. The telescopic plate 14 is fixedly installed on the top of the telescopic rod 13. The fixed frame 15 is fixedly installed on the bottom of the telescopic plate 14. The drive cylinder 16 is fixedly installed on the bottom of the fixed plate 11. The output end of the drive cylinder 16 is fixedly connected to the fixed frame 15.

[0020] When the material handling mechanism 3 is needed to rotate the PCB for material handling, the drive cylinder 16 operates, causing the telescopic plate 14 and telescopic rod 13 to move up and down along the hollow tube 12, thus enabling the material handling mechanism 3 to perform the up and down material handling steps.

[0021] Please see Figure 1 , Figure 2 and Figure 3The material handling mechanism 3 includes a first drive motor 17, a rotating disk 18, a material handling frame 19, a connecting pipe 20, and a suction head 21. The first drive motor 17 is fixedly installed at the bottom of the telescopic plate 14. The output end of the first drive motor 17 is fixedly connected to the rotating disk 18. The material handling frame 19 is fixedly installed on the outside of the rotating disk 18 at positions corresponding to the feeding frame 6, the unloading frame 7, and the load detection frame 8. Two sets of connecting pipes 20 are provided through the material handling frame 19, and the suction head 21 is provided through the bottom of the connecting pipe 20.

[0022] When the telescopic mechanism 2 drives the material-picking mechanism 3 to move up and down, the connecting pipe 20 is connected to the external air pump, so the suction head 21 can be used to adsorb the PCB. Then the telescopic mechanism 2 drives the material-picking mechanism 3 to move up. At this time, the first drive motor 17 drives the rotating disk 18 and the material-picking rack 19 to rotate. After the PCB board has moved, the telescopic mechanism 2 can drive the material-picking mechanism 3 to descend and place the material.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The feeding mechanism 9 and the discharging mechanism 10 have the same structure and both include a first fixed plate 22, a bearing plate 25, a threaded rod 26, a threaded sleeve 27, and a second drive motor 28. The bottom of the working frame 1 is fixedly installed with an "L"-shaped first fixed plate 22. Two sets of slide rails 23 are fixedly installed on one side of the first fixed plate 22. The bearing plate 25 is slidably connected to the slide rails 23 through a slider 24. The bottom of the working frame 1 is rotatably connected to the first fixed plate 22 with a threaded rod 26. The threaded sleeve 27 is threadedly connected to the outside of the threaded rod 26. One end of the threaded sleeve 27 is fixedly connected to the bearing plate 25. The second drive motor 28 is fixedly installed on the first fixed plate 22. The output end of the second drive motor 28 is fixedly connected to the threaded rod 26.

[0024] During the material feeding process, the second drive motor 28 operates, driving the threaded rod 26 to rotate. The rotating threaded rod 26 then drives the threaded sleeve 27 and the support plate 25 to move up and down, thus completing the PCB feeding and unloading steps. When the support plate 25 moves up and down, it can be limited by the slide rail 23 and the slider 24 to prevent deviation.

[0025] Please see Figure 1The visual inspection mechanism 5 includes a second fixing plate 29, a first mounting plate 30, and a visual inspection camera 31. The first mounting plate 30 is fixedly installed on the work frame 1 at the position corresponding to the unloading frame 7 via the second fixing plate 29. The visual inspection camera 31 is fixedly installed at the bottom of the first mounting plate 30. The barcode inspection mechanism 4 includes a third fixing plate 32, a second mounting plate 33, and a barcode scanner 34. The second mounting plate 33 is fixedly installed on the work frame 1 at the position corresponding to the carrying inspection frame 8 via the third fixing plate 32. The barcode scanner 34 is fixedly installed at the bottom of the second mounting plate 33.

[0026] When the PCB moves to the area below the vision inspection mechanism 5 and the barcode inspection mechanism 4, the barcode scanner 34 can scan the QR code on the PCB surface, which helps to achieve refined management and traceability. Meanwhile, the vision inspection camera 31 can quickly detect the soldering position and whether the components are missing on the PCB surface.

[0027] In use, the feeding frame 6, unloading frame 7, and load-bearing detection frame 8 can continuously identify and detect the PCB at different positions. The feeding mechanism 9 and unloading mechanism 10 can realize the automatic feeding and receiving process of the PCB. The telescopic mechanism 2 and the picking mechanism 3 work together to make the PCB move back and forth along the feeding frame 6, unloading frame 7, and load-bearing detection frame 8, so that the barcode detection mechanism 4 and vision inspection mechanism 5 can quickly detect the PCB. This automatic identification and error prevention has a high degree of automation and improves processing efficiency to a certain extent. When the picking mechanism 3 is needed to drive the PCB to rotate and pick it up, the drive cylinder 16 operates, driving the telescopic plate 14 and telescopic rod 13 to move up and down along the hollow tube 12, thus driving the picking mechanism 3 to perform the up and down picking steps. When the telescopic mechanism 2 drives the picking mechanism 3 to move up and down, the connecting pipe 20 is connected to the external air pump, so the suction head 21 can be used to pick up the PCB. B is adsorbed, and then the telescopic mechanism 2 drives the picking mechanism 3 to move upward. At this time, the first drive motor 17 drives the rotating disk 18 and the picking rack 19 to rotate. After the PCB board is moved, the telescopic mechanism 2 can drive the picking mechanism 3 to descend and place the material. When picking up and feeding, the second drive motor 28 operates and drives the threaded rod 26 to rotate. Then the rotating threaded rod 26 can drive the threaded sleeve 27 and the carrier plate 25 to move up and down. This completes the PCB feeding and discharging steps. When the carrier plate 25 moves up and down, it can be limited by the slide rail 23 and the slider 24 to prevent deviation. When the PCB moves to the bottom of the vision inspection mechanism 5 and the barcode inspection mechanism 4, the barcode scanner 34 can scan the QR code on the PCB surface, which helps to achieve refined management and traceability. The vision inspection camera 31 can quickly detect the soldering position and whether the components are missing on the PCB surface.
