[0036] Embodiment three:

[0037] Based on Example 2, Figure 4-5 and Figure 7-11As shown, the vacuum conveying mechanism 8 includes a first roller 801 that is vertically rotatably connected to the lower surface of the support plate 701; the first roller 801 is arranged between the first guide roller 5 and the second guide roller 6; a second roller 803 is vertically arranged on the side of the first roller 801 close to the mounting strip 702; the upper end of the second roller 803 is rotatably connected to the lower surface of the support plate 701; the lower end of the second roller 803 is coaxially fixed to the output shaft of a servo motor 803; the servo motor 803 is vertically bolted to the workbench 1; a third roller 804 is vertically arranged on the side of the second roller 803 close to the side support beam 201; the upper end of the third roller 804 is rotatably connected to the lower surface of the support plate 701; the first roller 801, the second roller 803 and the third roller 804 are connected through the conveying The conveyor belt 805 is connected by transmission; the part of the conveyor belt 805 located between the first roller 801 and the third roller 804 is arranged parallel to the peeling sheet 9; a plurality of negative pressure holes 806 are evenly distributed on the outer surface of the conveyor belt 805; a pair of baffles 807 are horizontally arranged on the inner side of the conveyor belt 805 from top to bottom; three accommodating notches 808 are opened at the edges of the two baffles 807, and the three accommodating notches 808 on each baffle 807 are respectively slidably matched with the circumferential side wall of the first roller 801, the circumferential side wall of the second roller 803 and the circumferential side wall of the third roller 804; a negative pressure chamber is formed between the two baffles 807 and the conveyor belt 805; the two baffles 807 are connected by a plurality of mounting rods 809; and the plurality of mounting rods 809 are vertically bolted to the support plate 701. When in use, a negative pressure chamber is formed between the two baffles 807 and the conveyor belt 805.
