Technical Field

[0001] The utility model relates to the technical field of PCB board welding clamping, in particular to a high-stability PCB board welding clamping device. Background Technique

[0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board and printed wiring board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Since it is made by electronic printing technology, it is called a "printed" circuit board. When existing PCB boards are welded in non-batch, individuals need to clamp and weld the PCB boards. The existing clamping and loading has the following problems. First, the fixture itself is small, so it is light in weight and unstable during welding, and the possibility of tipping over and other situations is relatively large. Second, the existing fixtures often clamp the two sides of the PCB board in a suspended manner by extrusion. This clamping method may cause the pressure on the PCB board to be too large during welding, resulting in the PCB board breaking. For this reason, we propose a high-stability PCB board welding clamping device to solve the above problems. Content of the Utility Model

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 work shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present invention: a high-stability PCB board welding clamping device, including a mounting bracket 1, a first fixing block 2 is fixedly installed on the right side of the mounting bracket 1, a movable block 3 is movably arranged on the left side of the mounting bracket 1, a rubber clamping block 4 is movably arranged at the upper end of the relative side of the movable block 3 and the first fixing block 2, a third fixing block 19 is fixedly installed on the movable block 3, a supporting disc 5 is movably arranged on the third fixing block 19, a positioning mechanism is arranged at the lower end of the movable block 3, and a supporting mechanism is arranged on the lower side of the mounting bracket 1. This structure enables the center position of the PCB board to be supported by the supporting disc 5 that can additionally support the PCB board, increasing the stability during device use. A supporting mechanism is also provided to reinforce the device body, further increasing the stability during device use;

[0021] Furthermore, the supporting mechanism includes a supporting block 6, the supporting block 6 is rotatably installed at the central position on the lower side of the mounting bracket 1, and the lower end of the supporting block 6 is flush with the lower end of the mounting bracket 1. This structure enables the device to achieve vertical support by rotating out the supporting block 6, increasing the stability during device use, and the device can be retracted into the mounting bracket 1 when not in use, increasing the convenience during device use.

[0022] Furthermore, placing grooves 7 are opened on both the left and right sides of the supporting block 6, and the distance between the two groups of placing grooves 7 is greater than the width of the mounting bracket 1. This structure enables the placing grooves 7 to provide the function of placing welding equipment or materials, further increasing the functionality during device use.

[0023] Furthermore, movable grooves 8 are provided at the upper ends of the first fixing block 2 and the movable block 3. Springs 9 are arranged in the movable grooves 8. Movable rods 10 are movably inserted into the movable grooves 8. One end of each movable rod 10 abuts against a spring 9. The movable rods 10 are fixedly installed on one side of the rubber clamping block 4. This structure enables the rubber clamping block 4 to expand and contract, thereby realizing the lateral extrusion and fixation of the rubber clamping block 4 on the PCB board to a certain extent.

[0024] Furthermore, the positioning mechanism includes sliders 11. Two groups of sliders 11 are fixedly installed on the lower side of the movable block 3. Sliding grooves 12 are provided on the mounting frame 1. The sliders 11 slide in the sliding grooves 12. A second fixing block 13 is fixedly installed at the lower end of the movable block 3. Two inserting holes 14 are provided in the second fixing block 13. Inserting blocks 15 are inserted into the inserting holes 14. A first screw sleeve 16 is fixedly installed at the central position of the upper end of each inserting block 15. A first screw rod 17 is rotatably installed at the central position of the second fixing block 13. The first screw sleeve 16 is threadedly sleeved on the first screw rod 17. This structure enables the movable block 3 to move, and fixes the displacement of the movable block 3 by pressing down the inserting blocks 15, increasing the adaptability and stability of the equipment during use.

[0025] Furthermore, a second screw sleeve 20 is fixedly installed on one side of the third fixing block 19. The second screw sleeve 20 is threadedly sleeved on a second screw rod 21. A support disc 5 is fixedly installed at the upper end of the second screw rod 21. This structure enables the position of the support disc 5 to be adjusted, thereby realizing the height adaptation to some electrical components on the back of the PCB board and increasing the adaptability of the equipment during use.

[0026] Furthermore, two rubber strips 18 are provided on the mounting frame 1. The positions of the rubber strips 18 are opposite to the positions of the inserting blocks 15. This structure increases the friction when the inserting blocks 15 are pressed against the mounting frame 1 and increases the stability of the equipment during use.

[0027] Furthermore, the left side of the third fixing block 19 is a triangular body, and a weight-reducing groove is provided on the left side of the third fixing block 19. This structure increases the support of the third fixing block 19.

[0028] Working principle: When in use, insert the PCB board between two groups of rubber clamping blocks 4, and then move the movable block 3 so that the rubber clamping blocks 4 squeeze the PCB board, thereby enabling the rubber clamping blocks 4 to fix the PCB board and causing the spring 9 to be squeezed by the movable rod 10. Then rotate the first screw rod 17 so that the first screw rod 17 makes the inserting block 15 descend and squeeze the rubber strip 18 through the threaded action with the first screw sleeve 16, thereby realizing the fixation of the movable block 3. Then rotate the second screw rod 21, and through the threaded action with the second screw sleeve 20, make the supporting disc 5 abut against the lower side of the PCB board, realizing the support for the PCB board body. Then turn out the supporting block 6 so that the supporting block 6 is perpendicular to the mounting frame 1 to form a stable support. The above is all the working principle of the present utility model.
