Problems solved by technology
Solder mask tape must be pasted manually, which is quite time-consuming and labor-intensive, and if it is not pasted correctly, it may lead to welding failure and produce too many defective products
In addition, aluminum alloy fixtures can easily absorb a large amount of heat from the tin furnace, resulting in poor welding products and seriously affecting the quality of circuit board welding.
Colleagues, the welding jig can only support the welding of one circuit board, and the circuit board is welded and placed for a certain period of time before taking it off, which is convenient for the solidification of the solder and prevents it from falling off later. At this time, the welding personnel can only rest or replace another Set of fixtures, resulting in a lot of waste of manpower and material resources

The invention relates to a circuit board welding fixture, which comprises a fixture frame, base boards and a top board. The top board is installed at the top of the fixture frame, clamping slots are arranged on the base boards, and welding holes are arranged on the top board and distributed corresponding to welding spots arranged on a circuit board of the clamping slots. The circuit board welding fixture further comprises a rotary table, which is installed at the bottom of the fixture frame. A telescopic rod which can move up and down is disposed at the center of the rotary table, at least one base board is arranged fixedly on the rotary table, and protrusions are arranged on both sides of the base boards. The top board and the base boards are of the same size, grooves are arranged on the reverse side of the top board, and the grooves correspond to the protrusions of the base boards. The circuit board welding fixture brings convenience for two persons to work cooperatively and for personnel arrangement and utilization, welding efficiency is improved, excessive accumulation of welding fluxes is avoided, and welding quality of circuits is improved.
Description
technical field [0001] The invention relates to a circuit board welding jig, which belongs to the technical field of circuit board welding jigs. Background technique [0002] With the advancement of science and technology, various electronic products have become an indispensable part of people's life. Among them, the display is an important component of multimedia electronic products, and there are many components to be controlled, as well as a variety of control signals. How to ensure the soldering quality of the display circuit board during the manufacturing process has become an urgent problem to be solved. [0003] However, the traditional soldering fixtures generally use aluminum alloy with a hollowed-out shape in the middle. The advantage lies in the commonality. It can be applied to any circuit board. However, in places where the pins are denser, it is necessary to cooperate with solder mask tape. Use to avoid solder balls or excessive solder sticking. Solder mask t...
