Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board welding, and more specifically, particularly relates to a circuit board welding clamping device. Background Art

[0002] During the repair or processing and production of circuit boards, welding operations need to be performed on the internal electronic components of the circuit board. When welding the circuit board, it is necessary to ensure that the circuit board remains stable during the welding process to prevent movement or tilting, thereby improving the welding quality. Therefore, a circuit board welding clamping device is required. Most of the existing circuit board welding clamping devices use manual, pneumatic, electric and other methods for clamping: manual clamping is achieved by manual operation (such as rotating a handle, pushing a slider, etc.) to clamp the circuit board; pneumatic clamping uses gases such as compressed air or nitrogen as the power source, and realizes the clamping of the circuit board through components such as cylinders or air valves; electric clamping realizes the clamping of the circuit board by driving transmission mechanisms such as lead screws and gears through a motor.

[0003] The existing application number CN202322867438.7 discloses a positioning fixture for circuit board welding, which relates to the field of circuit board welding positioning fixtures, including a board surface. Both sides of the upper end of the board surface are fixedly connected with support plates. The opposite sides of the support plates are fixedly connected with an adjustment component. The upper end of the adjustment component is fixedly connected with a push block. The upper end of the push block is provided with a fixing component. The lower end of the board surface is fixedly connected with a fastening component. The fastening component includes a housing arranged at the lower end of the board surface. With the above structure of the utility model, during the movement of the rubber pad, the air pressure at the bottom of the rubber pad becomes smaller, thereby generating suction, so that the device can be firmly fixed. The principle of this structure is similar to that of a suction cup, which is fixed by air pressure. When it is necessary to disassemble the fastening component, the device can be disassembled by controlling the electric push rod to rise so that the rubber pad is away from the housing, thus further increasing the practicability of the device by achieving convenient disassembly and assembly.

[0004] Based on the above, when the existing circuit board welding clamping device needs to perform welding operations on both sides of the circuit board, most of them need to first clamp and weld one side, then loosen the circuit board and clamp and weld the other side. Positioning is also required when re-clamping, and the operation is too cumbersome, affecting the welding efficiency of the circuit board. Moreover, a large amount of irritating gas is generated during the welding process, which has an impact on the staff. Summary of the Utility Model

[0005] To solve the above technical problems, the present utility model provides a circuit board welding clamping device to solve the problems that in the existing circuit board welding clamping devices, when two-sided welding operations need to be performed on a circuit board, it is mostly necessary to first clamp and weld one side, then loosen the circuit board and clamp and weld the other side.
