The invention relates to an automatic
assembly welding device used for
welding an auxiliary material on a workpiece. The automatic
assembly welding device comprises a rotation mechanism, carriers, a material pressure mechanism, a loading
manipulator, a taking and placing
manipulator, a welding
manipulator and a conveying mechanism; the rotation mechanism is composed of a bracket, a first
power component arranged on the bracket and a rotary platform which is connected with the first
power component; the rotary platform is provided with a first work
station and a second work
station which can both correspond to the loading manipulator and the welding manipulator; and the carriers are used for clamping the workpiece and are installed on the first work
station and the second work station. By adopting the automatic
assembly welding device, under the action of the material pressure mechanism, rapid and accurate attaching between the auxiliary material and the workpiece can be realized, and the welding quality of the auxiliary material and the workpiece is improved; and meanwhile, the first
power component drives the rotary platform to rotate, so that the loading manipulator, the taking and placing manipulator, the material pressure mechanism and the welding manipulator are ensured to carry out coordinated and orderly work, the middle wait time is eliminated, and the welding efficiency and quality of the automatic-assembly welding device are improved.
