A tooling fixture for convenient welding of circuit boards

Abstract

The invention discloses a fixture for welding circuit boards, which includes a base, a support cylinder, a slider, a support column, a gas pipe, a valve, a cylinder, a cylinder arm, a placement shell, a placement plate, an air pump, a connecting pipe, and a scale line , purification shell, activated carbon particle layer, filter screen, through hole, clear water layer, drain pipe, drain valve, water injection pipe, fixed plate, T-shaped block, limit block, thread groove, screw, rotating handle, splint, rotating column and pointer. This kind of injection mold that is easy to control the material flow speed has a simple structure, which is convenient for stably fixing the circuit board, improves the fixing effect of the circuit board, and at the same time facilitates the welding process of the surface of the circuit board by workers, reduces the scrap rate of circuit board welding, and is beneficial to workers. For welding operation, under the action of the cylinder driving the cylinder arm, it is convenient to adjust the height of the placement plate, and it is convenient for workers with different needs to weld, and it is easy to use.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a tooling fixture for welding circuit boards, and belongs to the technical field of tooling fixtures for circuit board applications. Background technique [0002] The names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. [0003] When the existing tooling fixtures for circuit boards are used, some existing tooling fixtures have a poor fixing effect on the welded circuit boards, and the circuit boards are prone to slide, w...

AI Technical Summary

Problems solved by technology

[0003] When the existing tooling fixtures for circuit boards are used, some existing tooling fixtures have a poor fixing effect on the welded circuit boards, and the circuit boards are prone to slide, which greatly increases the scrap rate of the circuit boards. During the welding process, the quality of the surrounding working environment is reduced due to the welding fume, which affects the work of the workers and affects the use
