Description

Technical Field

[0001] This utility model relates to the technical field of circuit board processing, specifically to a PCB circuit board pressing device. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board.

[0003] For example, a PCB board pressing device with authorization announcement number "CN219248196U" solves the problem that existing PCB board pressing devices have relatively simple functions and limited practicality. The aforementioned device uses a push plate positioned inside a circular hole. After pressing the circuit board, a return spring pulls the connecting plate back to allow the push plate to move within the circular hole, thus pushing the circuit board upwards for easy removal. However, considering existing PCB board pressing devices, electric equipment may require more training, has more complex operating procedures, and is prone to human error, especially with incorrect parameter settings, which could lead to pressing failure. This increases operational complexity, and electric equipment has more mechanical and electronic components, resulting in higher maintenance requirements. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing PCB board lamination devices, which have more complex operation steps, are prone to human error, and have higher maintenance requirements, and therefore proposes a PCB board lamination device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB circuit board pressing device, comprising a pressure plate and a protrusion, wherein the lower end of the pressure plate is fixedly connected to the protrusion, the upper end of the pressure plate is movably connected to a screw, the outer wall of the screw is threadedly connected to a base frame, and the inner wall of the base frame is machined with a sliding groove, wherein a limit mechanism is connected to the inner wall of the sliding groove.

[0006] Preferably, the limiting mechanism includes a slide bar, the outer wall of which is slidably connected to a slide groove, the upper end of which is fixedly connected to a limiting frame, and the inner wall of the limiting frame is machined with a placement groove.

[0007] Preferably, the inner wall of the base frame is threadedly connected to the fixing bolts, and the end of the base frame is connected to an adjustment mechanism.

[0008] Preferably, the adjustment mechanism includes a connecting plate, the end of which is rotatably connected to the base frame, the inner wall of which abuts against the circular block, and the upper end of which is fixedly connected to the extension plate.

[0009] Preferably, the end of the fixing bolt is threaded to the connecting plate.

[0010] Preferably, the lower end of the base frame is fixedly connected to the rubber anti-slip pad.

[0011] The PCB board pressing device proposed in this utility model has the following advantages: by inserting the circular block at the lower end of the extension board into circular grooves at different distances, the width between the extension board and the connecting board can be adjusted. The slide bar at the lower end of the limiting frame containing the PCB board is slid into the slide groove, and the pressure plate is placed on the upper end of the PCB board. The screw is manually turned and moves downward on the base frame, causing the screw to push the protrusion at the lower end of the pressure plate to press the PCB board. The pressing force is controlled manually, eliminating the need for personnel to adjust the force parameters, reducing human error and maintenance costs. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] Please see Figure 1-6In this embodiment, a PCB circuit board pressing device includes a pressure plate 1 and a bump 2. The bump 2 can be made of kraft paper or silicone, which can prevent uneven pressure during pressing. The lower end of the pressure plate 1 is fixedly connected to the bump 2, and the upper end of the pressure plate 1 is movably connected to the screw 3. The outer wall of the screw 3 is threadedly connected to the base frame 4. The inner wall of the base frame 4 is machined with a groove 5, and the inner wall of the groove 5 is connected to a limit mechanism 6.

[0022] The limiting mechanism 6 includes a slide bar 601, which can slide into the limiting frame 602 through both ends of the PCB circuit board to limit the placement position of the PCB circuit board. The outer wall of the slide bar 601 is slidably connected to the slide groove 5, and the upper end of the slide bar 601 is fixedly connected to the limiting frame 602. The inner wall of the limiting frame 602 is machined with a placement groove 603.

[0023] The inner wall of the base frame 4 is threadedly connected to the fixing bolt 7. The end of the base frame 4 is connected to the adjustment mechanism 8. By inserting the round block 802 at the lower end of the extension plate 803 into the round groove at different distances, the width between the extension plate 803 and the connecting plate 801 can be adjusted. The adjustment mechanism 8 includes the connecting plate 801. The end of the connecting plate 801 is rotatably connected to the base frame 4. The inner wall of the connecting plate 801 abuts against the round block 802. The upper end of the round block 802 is fixedly connected to the extension plate 803.

[0024] Insert the circular block 802 at the lower end of the extension plate 803 into circular grooves at different distances to adjust the width between the extension plate 803 and the connecting plate 801. Slide the slide bar 601 at the lower end of the limiting frame 602 containing the PCB circuit board into the slide groove 5, and place the pressure plate 1 on the upper end of the PCB circuit board. Manually turn the screw 3 to move downward on the base frame 4, so that the screw 3 pushes the protrusion 2 at the lower end of the pressure plate 1 to press the PCB circuit board. The pressing force is controlled by manual pressing, which eliminates the need for personnel to adjust the force parameters, reduces human error, and also reduces maintenance costs.

[0025] The end of the fixing bolt 7 is threaded to the connecting plate 801, and the lower end of the base frame 4 is fixedly connected to the rubber anti-slip pad 9.

[0026] Working principle:

[0027] First, based on the width of the PCB circuit board, insert the circular block 802 at the lower end of the extension board 803 into the circular slots at different distances to adjust the width between the extension board 803 and the connecting board 801. Then, push both sides of the PCB circuit board from the rear end into the placement slot 603 inside the limiting frame 602. At the same time, slide the slider 601 at the lower end of the limiting frame 602 into the sliding groove 5, so that the PCB circuit board on the limiting frame 602 is placed on the base frame 4. Then, place the pressure plate 1 on the upper end of the PCB circuit board. Manually turn the screw 3 to move downward on the base frame 4, so that the screw 3 pushes the protrusion 2 at the lower end of the pressure plate 1 to press the PCB circuit board.

[0028] After ensuring the resin flows and cures in the PCB circuit board during the pressing time, turn the screws 3 on the four angle base frames 4 in the opposite direction to disengage the protrusion 2 at the lower end of the pressure plate 1 from the PCB circuit. Then, move the slide bar 601 at the lower end of the limiting frame 602 out of the slide groove 5 to remove the PCB circuit board pressed by the limiting frame 602. At the same time, manually turn the fixing bolt 7 to disengage the end of the fixing bolt 7 from the connecting plate 801. Manually pry the base frame 4 to make the base frame 4 and the connecting plate 801 level. Turn the fixing bolt 7 again to press the end against the outside of the connecting plate 801 for fixation. The same operation is performed on the extension plate 803 to reduce the space occupied and make the overall layout neater. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
