[0003] Laser welding is an efficient, fast and advanced welding method. It uses a high-energy-density laser beam to melt metal materials and form a metallurgical welded joint. It has been widely used in recent years. If aluminum handrails can be mass-produced by laser welding, production efficiency will be greatly improved.

Specifically, by operating the operating button 23 on the left frame 1202, the front mold 101 is moved to a place where the frame 1202 is away from the rear mold 102 under the action of the first cylinder 104, and the front and rear side parts of the aluminum handrail are respectively placed in the V-grooves 105 of the front and rear molds 102, and the suction cups are used to fix the parts. 106, the parts are attached to the surface of the V-groove 105, and then the second clamping block 202 is moved into the V-groove 105 of the rear mold 102 under the second cylinder 203 by operating the operating button 23 on the left frame 1202, so as to clamp and fix the rear parts. At the same time, the first clamping block 201 is moved into the V-groove 105 of the front mold 101 under the action of the second cylinder 203, so as to clamp and fix the front parts. The front mold 101 is moved toward the rear mold 102 under the action of the first cylinder 104 by operating the operating button 23 on the left frame 1202, so that a welding seam is left at the upper and lower parts of the front mold 101 and the rear mold 102 when the molds are closed, and the connection seams of the front and rear parts of the aluminum handrail are exposed through the welding seams;Next, formal welding begins. The control button 29 is operated to start and control the welding assembly to move according to the pre-input working parameters under the action of the adjustment assembly, so that the first laser welding gun 302 moves to the position directly above the welding seam on the upper side of the front and rear molds 102. The first laser welding gun 302 moves along the horizontal x-axis direction while emitting a laser and passing the laser through the welding seam to weld the upper connecting seam of the aluminum handrail part. The second laser welding gun 402 moves to the position directly below the welding seam on the lower side of the front and rear molds 102. The second laser welding gun 402 moves along the horizontal x-axis direction while emitting a laser and passing the laser through the welding seam to weld the lower connecting seam of the aluminum handrail part, thereby completing the welding of an aluminum handrail part. At the same time, the operator places another aluminum handrail part to be welded into the right frame 1202 through the operation button 23 on the right frame 1202. Finally, the first The welding assembly 3 and the second welding assembly 4 are automatically transferred to another frame 1202 for work. Specifically, the first laser welding gun 302 and the second laser welding gun 402 are moved to the top of the right frame 1202 to weld another aluminum handrail part to be welded according to the pre-input working parameters. At the same time, the operator operates the operation button 23 on the left frame 1202 to move the front mold 101 to a place of the frame 1202 away from the rear mold 102 under the action of the first cylinder 104, and removes the welded aluminum handrail part from the left frame 1202, and collects the picture of the aluminum handrail part through the CCD camera 30 to monitor its quality, and then puts the new aluminum handrail part to be welded into the left frame 1202 for fixing and waiting for welding, thereby realizing the cyclic welding operation of the aluminum handrail parts between the two frames 1202 and realizing the uninterrupted welding production of aluminum handrail parts. ;
