Therefore, we need to design an auxiliary positioning device for circuit board inkjet printers, which adopts a counter-moving structure to clamp and fix the circuit board on both sides. It can adapt to the clamping of circuit boards of different sizes, fix the circuit board in the correct position, avoid blurry or incorrect printing due to positional deviation, prevent the circuit board from moving during the printing process, increase the printing accuracy, and improve the versatility and printing quality of the inkjet printer.

[0024] In the following description, embodiments of the auxiliary positioning device for circuit board inkjet printers of the present invention will be described with reference to the accompanying drawings.
[0025] Figure 1-5This invention illustrates an auxiliary positioning device for a circuit board inkjet printer according to an embodiment of the present invention. It includes a worktable 2 mounted on the bottom of an inkjet printing structure 1. A support plate 3 is fixedly connected to the central axis of the inner cavity of the worktable 2. A U-shaped frame 4 is fixedly connected to the top of the support plate 3. A bidirectional threaded rod 5 is rotatably connected to the central axis of the inner cavity of the U-shaped frame 4. Two opposing movable plates 7 are threadedly connected to the surface of the bidirectional threaded rod 5. Sliding blocks 8 are fixedly connected to the bottom of each movable plate 7. Guide rods 6 are provided on both sides of the front of the bidirectional threaded rod 5. The two ends of the guide rods 6 are fixedly connected to the U-shaped frame 4, and the guide rods 6 are slidably connected to the movable plates 7. The guide rods 6 allow the movable plates 7 to slide smoothly. During the sliding process of the moving plate 7 and the clamping plate 16, the guide rod 6 guides the moving plate 7, ensuring that the moving plate 7 does not shift when it drives the clamping plate 16 to slide, thus improving the stability of the clamping plate 16 during use. A track 9 is fixedly connected to the top of the inner cavity of the U-shaped frame 4, and the sliding block 8 is slidably connected to the inner wall of the track 9. A rotatable rotating rod 10 is installed through the right side surface of the U-shaped frame 4. A support block 11 is fixedly connected to the right side of the inner cavity of the U-shaped frame 4, and the motor 12 is fixedly mounted on the top of the support block 11. The support block 11 provides support for the motor 12 during use. This design prevents the motor 12 from falling off during use, improving its stability. The motor 12 is installed on the right side of the U-shaped frame 4's inner cavity. The output shaft of the motor 12 is fixedly connected to the rotating rod 10. A pulley 13 is fixedly connected to the right side of the rotating rod 10. A double-threaded rod 5 passes through the right side of the U-shaped frame 4 and is fixedly connected to a pulley 14. A belt 15 connects the pulley 13 and pulley 14. A clamping plate 16 is fixedly connected to the top of the two moving plates 7. The clamping plate 16 passes through the top of the worktable 2 and is slidably connected to the worktable 2. A support disc 17 is fixedly connected to the central axis at the top of the worktable 2. Connecting blocks 18 are fixedly connected to both the front and rear sides of the inner cavity of the U-shaped frame 4. The two connecting blocks 18 are slidably connected to the front and rear sides of the moving plate 7. Through the setting of the support disc 17, the support disc 17 provides a flat and stable support surface for the circuit board. During the inkjet printing process, the circuit board needs to remain stable to ensure the accuracy and clarity of the inkjet printing. The support disc 17 can prevent the circuit board from shaking or tilting, keeping it in the correct position and improving the accuracy of the inkjet printing position. The top of the worktable 2 is provided with a square groove for the clamping plate 16 to slide. The circuit board is placed on the top of the support disc 17, and the two clamping plates 16 are tightly attached to the circuit board.
[0026] Working Principle: When using this invention, the user places the circuit board on top of the support disc 17. Because the circuit board is placed on top of the support disc 17, the stable support prevents the printing from becoming blurry or misaligned due to the circuit board shaking. Then, the motor 12 on top of the support block 11 is turned on. The motor 12 drives the rotating rod 10 to rotate, which in turn drives the pulley 13 to rotate. The pulley 13, via the belt 15, drives the pulley 14 to rotate, causing the pulley 14 to drive the bidirectional threaded rod 5 to rotate within the U-shaped frame 4, thereby causing the bidirectional threaded rod 5 to rotate. The movable plate 7 on the surface of the textured rod 5 will move towards each other in the inner cavity of the U-shaped frame 4. At the same time, the movable plate 7 slides towards each other on the surface of the guide rod 6. The connecting block 18 limits the movable plate 7 to ensure that the movable plate 7 will not deviate when sliding. The movable plate 7 will drive the sliding block 8 to slide on the inner wall of the track 9. Then the movable plate 7 will drive the clamping plate 16 to slide towards each other on the top of the worktable 2. The clamping plate 16 clamps the two sides of the circuit board placed on the top of the support disc 17. Then the motor 12 is turned off. At this time, the circuit board is fixed. Finally, the inkjet printing structure 1 will print ink on the circuit board.
[0027] In summary, this circuit board inkjet printer uses an auxiliary positioning device. By placing the circuit board on top of the clamping plate 16, and then through the cooperation of the bidirectional threaded rod 5, pulley 13, and belt 15, the two moving plates 7 drive the two clamping plates 16 to clamp the two sides of the circuit board, thus fixing the circuit board. Subsequently, the worktable 2 inkjet prints on the circuit board. This achieves the goal of using a counter-moving structure to clamp and fix the two sides of the circuit board, which can accommodate circuit boards of different sizes, fix the circuit board in the correct position, avoid blurry or incorrect inkjet printing due to positional deviation, prevent the circuit board from moving during the inkjet printing process, increase inkjet printing accuracy, and improve the versatility and quality of the inkjet printer.
