Abstract

The invention relates to a laser welding machine. The invention discloses a double-light path fiber laser welding machine used for a plate solar heat absorber which includes a laser, a fiber and a focusing system. The laser is connected with the focusing system by the fiber. The invention also includes a base device and a goal-post device; wherein, the goal-post device is arranged on the base device; the focusing device is arranged on the goal-post device for inducing the laser emitted by the laser between the goal-post device and the base device. Aiming at the position of a workpiece to be welded, the focusing system can move along the three directions of X, Y and Z; wherein, X and Y refer to a horizontal direction parallel to the ground; Z refers to a direction vertical to the ground. The welding machine solves the welding difficulty between a copper tube and an aluminum plate and changes the manufacturing technique flow of a solar heat absorber, thus leading the quality of the solar heat absorber to be greatly improved.

Description

technical field [0001] The invention relates to a laser welding machine, in particular to a dual optical path fiber laser welding machine for a plate type solar heat absorber used for laser welding. Background technique [0002] Before the present invention was made, solar heat absorbers were all vacuum tube type. Since the vacuum tube is made of glass, this kind of heat absorber is difficult to process, has a short service life and is easily damaged. The solar heat absorber welded by copper tube and aluminum plate has the advantages of high energy conductivity, good mechanical strength, good reliability and repeatability, and long service life. It is widely used by foreign solar heat absorber manufacturers and is an updated product of solar heat absorbers. However, it is difficult to weld, and it is prone to problems such as missing welding, virtual welding, and easy corrosion. Moreover, welding is labor-intensive and time-consuming, which increases the cost of the product...
