Abstract

The invention discloses welding equipment for tin ball welding. The welding equipment comprises a spraying cavity, a laser module, a pneumatic module, a feeding module and a seal device. A tin ball fixing position is formed in the spraying cavity. A laser emitting port of the laser module is opposite to the tin ball fixing position and is used for heating a tin ball located at the tin ball fixingposition. An air outlet of the pneumatic module communicates with the spraying cavity and is used for spraying the machined tin ball. A conveying runner is formed in the feeding module and provided with a feeding port and a discharging port, and the discharging port communicates with the spraying cavity and is used for conveying the tin ball to the tin ball fixing position. The seal device is movably arranged on the feeding module so as to open or seal the feeding port. According to the purpose, the problems that in the laser tin welding process, spraying power control is poor, and the weldingprecision is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding equipment. Background technique [0002] Today's electronic products are becoming more and more sophisticated, the process is becoming more and more complicated, and the welding conditions are very harsh. For example, the solder joints are very small, the components cannot be passed through the furnace, and they cannot be close to the Luotie head with heat radiation. Traditional welding technology has been unable to solve these problems. , laser welding technology must be used, and laser spray tin welding is an important welding method in laser welding technology. It uses mechanical movement to transport a single tin ball to a designated injection point, and uses a laser to melt the tin ball. Then the molten tin balls are sprayed to the designated position by a certain pressure, but in the welding process, the welding accuracy and welding quality are often ser...
