Tooling jig facilitating welding of circuit board

Abstract

The invention discloses a tooling jig facilitating welding of a circuit board. The tooling jig comprises a base, a support cylinder, a slide block, a support column, a gas pipe, a valve, an air cylinder, an cylinder arm, a placement shell, a placement plate, an air pump, a connecting pipe, a calibration line, a purification shell, an activated carbon granular layer, a filter screen, a through hole, a water layer, a drainage pipe, a drainage valve, a water injection pipe, a fixing plate, a T-shaped block, a limit block, and a thread groove, a screw rod, a rotating handle, a clamping plate, a rotating column and a pointer. An injection mould with material flow speed easy to control is simple in structure, and can easily stably fix the circuit board, so that the fixing effect of the circuit board is improved; at the same time, it is easy for workers to perform the process of welding the surface of the circuit board, so that the rejection rate of the circuit board welding is reduced, and the injection mould is convenient for the workers to carry out welding operation; and the placement height of the placement plate is convenient to adjust under the action of the air cylinder arm drivenby the air cylinder, so that the injection mould is convenient to weld for the workers with the heights of different requirements, and is convenient 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.

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
