An automatic laser welding arm

Abstract

The invention discloses an automatic laser welding arm, which relates to the technical field of laser welding arms. In the invention, a laser welding head is connected to a support arm by a welding oscillation mechanism, and a protective gas injection head is connected to the support arm by a swing mechanism. In this way, when the laser welding head is welding, the controller controls the welding oscillating mechanism to drive the laser welding head to reciprocate in the width direction of the weld; and the controller also controls the laser welding head to move along the The laser welding head swings in the direction of welding feed, so that the uniformity of welding can be improved. Even if the weld is large, it can effectively make all the positions of the weld be heated evenly, and the uniformity of thermal fusion can be improved. Ensure the reliability and stability of welding, improve the uniformity of welding, solve the problem of overheating and melting at the center of the welding head only to increase the welding power, and cracks are prone to appear at the joint of the weld, and improve the firmness of welding.

Description

technical field [0001] The invention relates to the technical field of laser welding arms, in particular to an automatic laser welding arm. Background technique [0002] Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding. When performing laser welding It is necessary to utilize the welding arm, which can effectively weld the workpiece effectively. [0003] However, when the current welding arm is welding the workpiece, especially when the weld seam is wide, it is difficult for ordinary power welding equipment to perform effective welding, and if only the welding power is increased, then for large weld seams It is easy to cause local overheating and unreliable edge welding fusion, resulting in cracks in the edge welding, which makes it d...

Problems solved by technology

[0003] However, when the current welding arm is welding the workpiece, especially when the weld seam is wide, it is difficult for ordinary power welding equipment to perform effective welding. It is easy to cause local overheating and unreliable edge welding fusion, resulting in cracks in the edge welding, which is difficult to meet the reliability and safety of welding

Moreover, during long-term use of the welding arm, it is easy to cause dust, and the dust enters the welding arm and causes damage, which affects the life of the welding arm
