Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding, in particular to a kind of semi-automatic threading welding method. BACKGROUND

[0002] In product design, two square printed boards need to be soldered on the rectangular printed board side by side. It is required that all pads of the upper and lower printed boards should be overlapped, and the pad holes should be concentric. The distance between the pads on the printed board is very small, and if the pads are skewed, short circuit will be caused with the surrounding pads. Silver-plated wire is used to fix and solder by threading through the upper and lower overlapped pad holes, but the silver-plated wire cannot be fixed in position and length after being vertically inserted into the pad hole, and the operation difficulty is very large when all pads are threaded and soldered. The product has a large flat area, and the operator can only operate on the product. If the length of the silver-plated wire is cut on the product, there is a risk of bringing in metal wires and other excess materials.

[0003] A threading limiting welding tool is designed in the early stage, which solves the above problems and guarantees production efficiency and product quality. However, this tool can only be used by one operator to complete the steps of fixing, threading and soldering of a group of printed boards on the product at one time, which is a serial work mode and is not conducive to the production schedule. Therefore, a split type welding device is needed to improve production efficiency and guarantee welding quality. SUMMARY
