摘要： The present invention provides a laser welding device, which performs welding of an electrode lead and an electrode tab by irradiating laser so that the laser sequentially passes through an opening hole of a base plate and an opening hole of an upper mask when the electrode lead and the electrode tab are seated on a lower mask in a state in which a laser irradiator, the base plate, and the upper mask are coupled to each other, the laser welding device including: the base plate provided with a coupling tool that protrudes from one surface thereof; and the upper mask provided with a coupling hole through which the coupling tool enters and coupled to the base plate by coupling the coupling tool to the coupling hole, wherein the coupling tool comprises a cylinder which has a hollow shape therein in a longitudinal direction and in which an air hole is punched, a piston which is capable of being slid inside the cylinder in a state of being coupled to a spring and has a section of which a diameter is reduced toward one side thereof, and a ball coupled to the cylinder, and wherein, when the coupling tool enters the inside of the coupling hole, the ball enters a groove formed in an inner circumferential surface of the coupling hole by the piston so as to be prevented from being separated, and when air is injected into the air hole, the piston is slid to separate the ball from the groove.
