[0003] Especially during the printing process, traditional fixing components often block the corner parts of the circuit board, making printing in these areas difficult or impossible. In addition, due to the various sizes of integrated circuit boards, traditional fixing components often lack sufficient flexibility and adjustability and cannot adapt to circuit boards of different sizes. In view of this, we propose a four-corner fixing component of an integrated circuit printing device. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0025] The four-corner fixing assembly of the integrated circuit printing device includes a placement board 1 at the lowest position. A clamping assembly 2 is movably installed at each of the four corners of the placement board 1. The clamping assembly 2 includes an L-shaped baffle 20. A guide rail 21 is integrally formed at the corner of the L-shaped baffle 20. An L-shaped movable frame 22 is slidably installed on the guide rail 21. A pressure plate 23 that can move up and down is provided below the L-shaped movable frame 22. An electric telescopic rod 24 for driving the pressure plate 23 to move up and down is installed on the L-shaped movable frame 22. An adjusting assembly 3 is provided between the clamping assembly 2 in the lower left corner and the two adjacent clamping assemblies 2. The adjusting assembly 3 is slidably connected to the top of the placement board 1. By providing the pressure plate 23 that can move along the guide rail 21, during printing, especially at the corners of the printed circuit board, the pressure plate 23 on the corner to be printed can be separated from it without blocking the upper part, facilitating the printing of the corners of the circuit board. At the same time, the adjusting assembly 3 can adjust the relative positions between the clamping assemblies 2 to adapt to integrated circuit boards of different sizes, improving the flexibility and applicability of the device.

[0026] Preferably, in this embodiment, two strip grooves 10 respectively slidably connected to the two adjusting assemblies 3 are opened on the top of the placement board 1. The movement direction of the adjusting assembly 3 can be restricted by the provided strip grooves 10.

[0027] Preferably, at one end of the guide rail 21 away from the L-shaped baffle 20, an extension plate 211 extending upward is integrally formed. An adjusting screw rod 25 threadedly connected to the L-shaped movable frame 22 is rotatably installed on the extension plate 211. A second servo motor 26 for driving the adjusting screw rod 25 to rotate is installed on the outer wall of the extension plate 211. Through the design of the extension plate 211, the adjusting screw rod 25, and the second servo motor 26, the precise movement of the L-shaped movable frame 22 can be realized, and then the position of the pressing plate 23 can be precisely controlled to ensure that it can clamp or disengage from the corner of the circuit board.

[0028] Preferably, a threaded hole 220 threadedly connected to the adjusting screw rod 25 is formed on the L-shaped movable frame 22. A limiting block 221 is integrally formed at the bottom of the adjusting screw rod 25. A limiting groove 210 slidably connected to the limiting block 221 is formed at the top of the guide rail 21. Through the design of the threaded hole 220, the limiting block 221, and the limiting groove 210, it can be ensured that the L-shaped movable frame 22 moves smoothly and accurately on the guide rail 21, preventing it from falling off or shifting.

[0029] Preferably, the adjusting assembly 3 includes a slider 33 slidably connected to the strip-shaped groove 10. Two side plates 34 are symmetrically and fixedly connected to the top of the slider 33. A driving gear 31 and a driven gear 30 that are meshed are rotatably installed between the two side plates 34. A first servo motor 32 for driving the driving gear 31 to rotate is installed on the outer wall of the side plate 34. The design of the adjusting assembly 3 enables it to slide on the strip-shaped groove 10. At the same time, through the meshing of the driving gear 31 and the driven gear 30, and the driving of the first servo motor 32, the precise adjustment of the position of the clamping assembly 2 is realized, further improving the flexibility and precision of the device.

[0030] Preferably, two threaded rods 5 respectively threadedly connected to the L-shaped baffles 20 on both sides of the adjusting assembly 3 are coaxially fixed on the driving gear 31. Through the design of the threaded rods 5, the rotation of the driving gear 31 can be converted into a linear motion of the clamping assembly 2, further realizing the precise control of the position of the clamping assembly 2.

[0031] Preferably, a guide rod 4 is provided between the clamping assembly 2 at the upper right corner and the two adjacent clamping assemblies 2. The guide rod 4 is inserted and connected to the L-shaped baffles 20 at both ends thereof. The design of the guide rod 4 increases the stability between the clamping assemblies 2, prevents them from shifting or twisting during the adjustment process, and ensures the accuracy and stability of clamping.

[0032] Preferably, the thread directions of the two threaded rods 5 installed on the same adjusting assembly 3 are opposite. Such a design can ensure that when the driving gear 31 rotates, the two clamping assemblies 2 can move towards the center or both sides simultaneously, further improving the efficiency and accuracy of the adjustment.

[0033] When the four-corner fixing component of the integrated circuit printing device of the present utility model is in use, first, place the integrated circuit board to be printed on the placement board 1. Then, fix the four corners of the circuit board by adjusting the four clamping components 2.

[0034] Each clamping component 2 is equipped with a movable pressing plate 23, which can move up and down driven by an electric telescopic rod 24. During the printing process, when it is necessary to print the corner of the circuit board, the corresponding pressing plate 23 can be lifted by controlling the electric telescopic rod 24, and the adjusting screw rod 25 is driven to rotate by the second servo motor 26. Since the adjusting screw rod 25 is threadedly connected to the L-shaped movable frame 22, the L-shaped movable frame 22 will move along the guide rail 21, thereby driving the pressing plate 23 to move outward from the circuit board, so that it is separated from the corner of the circuit board and does not cause occlusion to the printing.

[0035] In order to adapt to integrated circuit boards of different sizes, the present utility model is provided with an adjusting component 3 for adjusting the distance between adjacent clamping components 2. The adjusting component 3 slides in the strip-shaped groove 10 through the slider 33, so that its position can be adjusted. At the same time, the meshing of the driving gear 31 and the driven gear 30, and the driving of the first servo motor 32 can accurately adjust the position of the clamping component 2. When the driving gear 31 rotates, it drives the threaded rod 5 to rotate. Since the threaded rod 5 is threadedly connected to the L-shaped baffle 20, the L-shaped baffle 20 will move along the axis direction of the threaded rod 5, thereby changing the position of the clamping component 2.

[0036] In addition, in order to further improve the synchronization of the movement of the clamping component 2, the present utility model is provided with a guide rod 4 between the clamping component 2 in the upper right corner and the two adjacent clamping components 2. The guide rod 4 is inserted and connected to the L-shaped baffle 20, providing a stable guide for the movement of the clamping component 2 and preventing it from shifting or twisting during the movement.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
