PURPOSE:To perform high-speed spot welding at a prescribed position only by setting electronic parts by constituting a table having a rack and a rotatable shaft at a position corresponding to the cam of a rotary part. CONSTITUTION:When a shaft 6 is rotated, a fixed cam 13 engages the groove of a rack 36 with a play to rotate. Then when the peak and a bearing 41 come into contact with each other, the upper electrode 50 of a spot welder 14 is lowered through levers 40 and 45, etc., to spot-weld electronic parts on the top surface of the lower electrode 29. When it is further rotate, a moving cam 16 separates from the rack 36 and a cam 16 comes into contact with a cam 13 through the operation of a spring 17. When it is further rotated, the rack 36 moves to move electronic parts set on a table 22 through a jig 26 at the same pitch with the rack 36, and the electronic parts are spot-welded at a next spot position by the cam 25 similarly. |
