Description

For different welding products, the location of the soldering point and the fixing fixture will affect the accurate delivery of the tin wire. How to solve this problem is a difficult problem in automatic soldering of tin wire. At present, the laser automatic soldering machine uses a rotating mechanism to drive the tin feeding head to rotate to improve the welding accuracy.
[0003] There are two commonly used rotating mechanisms in laser automatic soldering machines on the market: one is that the tin wire head adjustment part and the laser welding device are installed together, and the whole is installed on a rotating shaft for rotation; the other is that the tin wire head adjustment part is installed on the laser output head, but during the welding process, it needs to be manually adjusted for rotation.
