LASER WELDING MACHINE AND LASER WELDING METHOD USING THE SAME

摘要

A laser welding machine includes: an elevator that is capable of sliding an elevating platform; a pressing actuator that is fixed to the elevating platform at a base part of the pressing actuator and has a tip slidably connected to the base part and pressing a conductive upper terminal toward a conductive lower terminal; a laser oscillator; a machining optical device that is fixed to the elevating platform and has a lens to focus the laser light emitted from the laser oscillator; a position detector that detects a vertical positioning of the pressing actuator; a counter that receives an output of the position detector and delivers position information; and a control circuit that controls, based on the received signal from the counter, the elevator, the pressing actuator, and the machining optical device, and controls operation of the laser oscillator.
