Disclosure of Invention
The invention aims to solve the technical problems of providing an auxiliary clamp and a method for welding a holder circuit board, and solving the problems that the existing circuit board clamp is unstable in clamping, the circuit board cannot be overturned in the welding process, and direct-insertion electronic elements cannot be fixed.
In order to solve the above problems, the technical solution to be solved by the present invention is:
the utility model provides a cloud platform circuit board welding is with supplementary anchor clamps, includes the bottom plate, and bottom plate middle part articulates there is the U-shaped support frame, and it has the installing frame to articulate in the support frame, is equipped with the slide bar on the installing frame, and threaded connection has first jackscrew on the slide bar, many first guide arms of fixedly connected with on the installing frame, and the clamp plate assembly is on each first guide arm, and threaded connection has many the second jackscrews that are the same as with the clamp plate on fixed to first guide arm on the clamp plate, is connected with flexible kicking block on the clamp plate.
A method for welding a circuit board by using an auxiliary fixture for welding a holder circuit board comprises the steps of fixing the circuit board to be welded on a mounting frame, enabling a direct-insertion electronic element on the circuit board to abut against a flexible top block, and supporting the electronic element by using the flexible top block; after the inclination angle and the direction of the mounting frame are adjusted, the inserted electronic element is welded.
The invention has the technical effects that: the stress of the circuit board can be uniform during clamping, and the stability of the circuit board in the welding process is improved; the design similar to a tripod head is adopted, so that the circuit board can rotate 360 degrees in the axial direction and the radial direction after being clamped stably; and the auxiliary clamp is provided with an element pressing plate made of flexible materials and used for fixing the direct-insertion type elements at one time, so that all welding processes of the circuit board can be completed through one-time clamping, and the welding efficiency is improved.
