[0022] like Figure 2-Figure 4 As shown, a plurality of balls 12 are rotatably mounted on the supporting plate 5. The supporting plate 5 equipped with the plurality of balls 12 can facilitate the movement of the thin plate. A plurality of reinforcing plates 15 are fixedly connected between the side plate 6 and the supporting plate 5, wherein two reinforcing plates 15 are respectively threadedly connected with fixing screws 16. Two insertion holes 13 are provided in the side plate 6, and a positioning rod 14 is inserted into the insertion hole 13. A card slot 17 is provided at one end of the positioning rod 14, and an angle block 18 is also provided at one end of the positioning rod 14. A card block 19 is fixedly mounted on the angle block 18 relative to one end of the positioning rod 14. The transverse cross-section of the card block 19 is T-shaped, and the card block 19 is inserted into the card slot 17. With the help of the adjustable positioning rod 14 and the replaceable angle block 18, a correction positioning can be performed for thin plates with different bevels, thereby ensuring the alignment of the connection between the two thin plates.

[0023] like Figure 2 、 Figure 5 As shown, a crossbeam 20 is fixedly installed on the side of the side panel 6 away from the reinforcing plate 15, and two axle seats 21 are fixedly installed at the bottom of the crossbeam 20. Two guide rods 22 are fixedly connected between the two axle seats 21.

Then, the two sliders 9 respectively cooperate with the electric telescopic cylinder 10, the pressure rod 11, and the pressure block 23 to drive the two thin plates to move relative to each other on the corresponding support plate 5, so that when the pressure block 23 drags the thin plate to move, the thin plate will not rotate. Then, the slide 3 can be started by the controller to move on the two guide rails 2, and the laser generator 4 can be used to weld the connection between the two thin plates.
