The handling device 300 includes a top base 310 and a mechanical arm 320, the mechanical arm 320 is disposed on the frame 100, the top base 310 is disposed at an execution end of the mechanical arm 320, the top base 310 is provided with a suction head 340 for sucking the upper plate 20, the mechanical arm 320 is used for driving the top base 310 to butt against the base 210, so that the lower plate 10 is attached to the upper plate 20, and the orientation of the lower through hole 11 is opposite to the orientation of the upper through hole 21. The laser device 400 is disposed on the frame 100, the top base 310 is provided with a light-passing hole 314 aligned with the upper through hole 21, and the laser device 400 emits laser to the butt joint position of the lower through hole 11 and the upper through hole 21 through the light-passing hole 314, so that the lower plate 10 and the upper plate 20 are welded and connected at the butt joint position of the lower through hole 11 and the upper through hole 21. Wherein, each positioning element 220 has a mating surface 221, and the top base 310 is provided with a plurality of driving surfaces 313 to be matched with each mating surface 221 one by one; in the process of docking the top base 310 with the base 210, the driving surface 313 and the mating surface 221 slide relatively to push the positioning member 220 to move toward the preset position 211.
Specifically, an external robot places the lower plate 10 at a predetermined position 211 on the base 210 and between the respective positioning members 220. It should be noted that, when the lower plate 10 is placed, there may be a slight deviation between the placement position of the lower plate 10 and the preset position 211. At the same time, the mechanical arm 320 controls the top base 310 to move to the material taking position, the top base 310 sucks the upper plate 20 with the suction head 340, and the upper through hole 21 of the upper plate 20 is just aligned with the light passing hole 314.

In addition, the top base 310 shields the upper surface of the upper plate 20, thereby preventing the laser from being irradiated to the upper surface of the upper plate 20, and further preventing the upper plate 20 from being scrapped.
To sum up, in order to achieve the positioning of the components, a plurality of driving structures are generally used to control the positioning members 220 to move towards each other, and the positioning members 220 cooperate to clamp the components, so as to maintain the positions of the components, so as to perform subsequent processing, such as laser welding, on the components. In the present disclosure, during the process of docking with the base 210, the top base 310 may be utilized to slide relatively with the mating surface 221 of the positioning element 220 through the driving surface 313, so as to push each positioning element 220 to move toward the preset position 211, thereby correcting and maintaining the position of the lower plate 10, and further ensuring that the laser device 400 can accurately perform laser welding on the lower plate 10 and the upper plate 20.
