The laser welding tool comprises a linear drive (12) by which laser radiation is movable along a welding seam, where the laser is a fiber laser that comprises a fiber (8) for lighting wire, an optics for coupling the laser beam, a radiation source in the fiber, and a collimator (9) connected with the fiber for focusing the progression of the laser radiation. The collimator is arranged on the linear drive that enables a movement of the collimator along a predetermined movement line (13). The linear drive is arranged with the collimator in a housing having an outlet slit (17). The laser welding tool comprises a linear drive (12) by which laser radiation is movable along a welding seam, where the laser is a fiber laser that comprises a fiber (8) for lighting wire, an optics for coupling the laser beam, a radiation source in the fiber, and a collimator (9) connected with the fiber for focusing the progression of the laser radiation. The collimator is arranged on the linear drive that enables a movement of the collimator along a predetermined movement line (13). The linear drive is arranged with the collimator in a housing having an outlet slit (17) for the laser radiation. The movement line of the collimator passes parallel to the outlet slit and the collimator is aligned so that the laser radiation is escaped through the outlet slit from the housing. The fiber laser is activatable, when the outlet slit of the housing resets on one of the workpiece. The housing rejuvenates itself toward the outlet slit in funnel-shaped manner. The laser welding tool is arranged as welding tongs with a tong frame, a lower tool arranged on the tong frame, and a displacement unit moving the housing against the tong frame. A pressure piece exists itself at the free end of the lower tool. The pressure piece and the aligned outlet opening are movable by the processing unit. The pressure piece corresponds to the form of the outlet slit. The processing unit comprises a positioning drive held on the tong frame, a housing reception and/or a linear guidance for the housing reception. The linear drive comprises a linear sled for the collimator, where the linear sled is connected with a positioning drive. A switching element is arranged on the housing and activates an energy supply of the fiber laser on one of the workpiece during resting the outlet slit. The balancing module comprises a balancing base framework for mounting on the robot arm. A linear guidance is arranged for the tong frame with movement direction like the linear guidance on the balancing base framework. The balancing module comprises a short stroke linear drive acting on the tong frame, where the flux of the linear drive is turned to a spring pressure. A weaving generator is arranged between the collimator and the carrier element of the linear drive guiding along the pre-determined moving line. |
