PURPOSE: A laser welding system is provided to save cost by semi-eternally using a transmission unit after extending the life span of the transmission unit. CONSTITUTION: A transmission unit of a laser welding system is composed of a first cam(70), a lever(72) rotated by the first cam, a first shaft(74) moved right and left by a lever(72), an absorbing unit(76) installed on an end of the first shaft, a second cam(78) coaxially rotated with the first cam, a second shaft(80) moved up and down by the second cam and a guide block(82) for connecting the second shaft with the first shaft. Herein, if the first and second shafts are elevated upward by the second cam and reach a certain height, the lever is rotated by the first cam, and at the same time, the first shaft is elastically backed up to the original state. In addition, the lever reaches a position to absorb a product since the first and second shafts are dropped. |
