Problems solved by technology

[0002] Traditional wire welding directly uses an electric soldering iron to solder the tin wire to the solder joint between the wire rod and the connecting terminal. The solder joint is not firmly connected, which may easily cause a short circuit or solder drop, which will affect the normal use of the wire end. Tin wire welding It can't completely cover the thread end, it is easy to break and fall off, and the service life is not long
Directly using ordinary tin wire will cause uneven melting of tin at the soldering point, and the shape is irregular, which will affect the appearance
At present, most manufacturers still use the traditional welding process, mostly using manual or semi-automatic step-by-step welding, which causes a lot of waste of manpower and material resources, and the work efficiency is not high, and the product quality is uneven, which affects product quality. Therefore, the market urgently needs A process method that can complete the welding process fully automatically and has good soldering effect

Abstract

The invention relates to the technical field of power source DC line welding, in particular to power source DC line welding and tin soldering processes. The power source DC line welding process comprises the steps of performing heating to reach 280-400 DEG C and obtain liquid tin; performing visual detection and identification to obtain a PCB; carrying out secondary positioning identification on the PCB; spraying a soldering flux material; inserting a DC line; performing tin soldering process processing on a position where tin is to be soldered and the DC line is already inserted; visually detecting whether the soldering result is qualified or not; and performing next processing on the PCB which is judged to be qualified, wherein the tin soldering effect is excellent according to parameters and steps in the tin soldering process, and the condition that tin soldering is carried out through a soldering iron does not happen. Because tin wires contain rosin, exploding tin beads can form easily and be attached to the PCB during welding, solder balls fall off from packaged products after long time, abnormal sounds are generated when products are shaken, and batch reworking of products iscaused. The product quality and the production efficiency are improved.
