Intelligent automatic positioning laser welding equipment

The invention discloses intelligent automatic positioning laser welding equipment and relates to the technical field of laser welding, the intelligent automatic positioning laser welding equipment comprises a rack and a turn-over assembly, electric lifting rods are arranged at the left end and the right end of the rack, a lifting frame is connected to the tops of the electric lifting rods, and the turn-over assembly is arranged at the bottom of the lifting frame; the turn-over assembly comprises a toothed plate, a reset spring, a ratchet wheel, a worm, a fixing frame, a pawl, a worm gear, a rotating shaft and a connecting base. When the bottom of a workpiece needs to be welded after the top of the workpiece is welded, the electric lifting rod only needs to drive the lifting frame to move upwards, the workpiece is prevented from colliding with the welding machine head when turned over, and after the lifting frame moves upwards by a certain amplitude, the tooth part of the toothed plate can be attached to the r
