[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a printing apparatus for circuit board processing and forming, comprising:

[0022] Base 1 and printing press 2 mounted on base 1;

[0023] The circuit board conveying mechanism includes two rotating columns 3 mounted on a base 1. A cam divider 4 is installed on the base 1. One rotating column 3 is fixedly connected to the output shaft of the cam divider 4, while the other rotating column 3 is rotatably mounted on the base 1. The cam divider 4 has a high-precision indexing function, which can ensure that the rotation angle of each rotating column 3 is accurate, thereby ensuring the accuracy of the circuit board conveying position, that is, conveying it to the bottom of the printing press 2.

[0024] Each of the two rotating columns 3 is equipped with two sprockets 8, which are horizontally opposite each other and connected by chains 9. Multiple guide rods 10 are mounted on the two chains 9, and the multiple rods 10 are evenly distributed on the chains 9. The evenly distributed rods 10 ensure uniform intervals in the circuit board conveying process, which facilitates precise printing by the printing press 2.

[0025] The base 1 is equipped with a guide plate 14 that matches the shape of the chain 9. The guide plate 14 has a T-slot 11, within which a T-block 12 is slidably connected. The T-block 12 is fixedly connected to the vertical rod 10. This structure ensures that the vertical rod 10 remains stable during movement and does not shift, thus ensuring smooth transport of the circuit board on the placement tray 7. A bracket (not shown in the diagram, but its shape and number can be customized according to actual needs) can be installed at the bottom of the guide plate 14. The bracket can be made of high-strength aluminum alloy, ensuring both support stability and reducing the overall weight of the device.

[0026] A support plate 13 is welded to the upper end of the vertical rod 10, and the placement tray 7 is fixed to the support plate 13 by bolts, so that different sizes of placement tray 7 can be replaced according to different specifications of circuit boards.

[0027] The upper end of the placement tray 7 is provided with a circuit board placement slot 5. The size of the circuit board placement slot 5 is designed according to common circuit board specifications, and the inner wall of the slot is lined with an anti-static rubber pad to prevent the circuit boards from attracting dust or shifting due to static electricity during transportation. The drive wheel 8 rotates, driving the chain 9 to rotate, which can transport the circuit boards in the placement slot 5 one by one to the bottom of the printing machine 2.

[0028] One end of the placement tray 7 has a notch 6, which connects to the circuit board placement slot 5, facilitating manual removal of the printed circuit board. When the circuit board needs to be removed, the operator's fingers contact the circuit board through the notch 6, thus providing the operator with more operating space and making it easier to remove the circuit board.

[0029] Printing press 2 employs high-precision inkjet printing technology. The printhead features an automatic cleaning function, periodically cleaning the printhead to prevent clogging and ensure print quality. Above the printing area of ​​printing press 2, an adjustable light shield made of opaque material effectively blocks external light interference, ensuring the clarity and color accuracy of the printed pattern. The light shield is mounted on the frame of printing press 2 via slide rails and its position and angle can be adjusted as needed, a feature of existing technology.

[0030] In addition, an infrared positioning device (not shown in the figure) can be installed below the printing press 2. The infrared positioning device can emit infrared rays. When the placement tray 7 is transported to the printing position, the infrared rays illuminate a specific position in the circuit board placement slot 5, providing the operator with a precise positioning reference, ensuring the accurate placement of the circuit board, and further improving the printing accuracy.

[0031] According to the specifications of the circuit board to be printed, select a suitable placement tray 7 and fix it to the support plate 13 at the upper end of the vertical rod 10 with bolts. Ensure that the placement tray 7 is firmly installed and the circuit board placement slot 5 is oriented correctly. The circuit board placement operator carefully places the circuit board to be printed into the circuit board placement slot 5 on the placement tray 7. Since the dimensions of the circuit board placement slot 5 are designed according to common circuit board specifications, and the inner wall of the slot is lined with anti-static rubber pads, it can effectively prevent the circuit board from attracting dust or shifting due to static electricity during transportation, ensuring the stability of the circuit board placement.

[0032] The cam divider 4 starts working, driving the rotating column 3, which is fixedly connected to its output shaft, to rotate. Since two sprockets 8 are installed on each of the two rotating columns 3, and the two horizontally opposite sprockets 8 are connected by a chain 9, the rotation of one rotating column 3 will drive the other rotating column 3 to rotate synchronously, thereby causing the chain 9 to start moving.

[0033] Multiple vertical rods 10 are mounted on a chain 9 and are evenly distributed. As the chain 9 moves, the vertical rods 10 slide in the T-slots 11 within the guide plate 14. The T-blocks 12 are fixedly connected to the vertical rods 10, ensuring that the vertical rods 10 remain stable and do not shift during movement. The movement of the vertical rods 10 causes the support plate 13 and the placement tray 7 at their upper ends to move synchronously, conveying the circuit board placement slots 5 one by one to the bottom of the printing press 2.

[0034] Infrared positioning: When the placement tray 7 is conveyed to the printing position, the infrared positioning device installed below the printing machine 2 emits infrared rays, which illuminate a specific position within the circuit board placement slot 5. The operator then fine-tunes the position of the circuit board based on the infrared illumination position to ensure accurate placement and guarantee precise printing in the future.

[0035] Start printing press 2. Printing press 2 uses high-precision inkjet printing technology to accurately print the preset marking pattern onto the circuit board. After the circuit board printing is completed, the circuit board conveying mechanism continues to operate, transporting the printed circuit board to a position accessible to the operator.

[0036] The operator's fingers contact the circuit board through the notch 6 at one end of the placement tray 7. The notch 6 is connected to the circuit board placement slot 5, providing the operator with more operating space and making it easier for the operator to easily remove the printed circuit board from the circuit board placement slot 5 and then place a new circuit board.

[0037] Through the above working process, the printing device of this utility model embodiment can efficiently and accurately complete the inkjet printing of circuit boards, meeting the requirements of circuit board processing and forming.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
