The two ends of the suction mechanism 3 are liftable along a third direction 8 to press the edges of the workpieces, and a gluing mechanism 5 which is arranged at the top of the other end of the rotating mechanism 2 and is movable along the first direction 6 and the second direction 7 and liftable along the third direction 8 to glue the workpieces on the suction mechanism 3.

[0066] The workpiece to be cut is placed on the suction mechanism 3 below the cutting mechanism 4 by manual operation, and then the suction mechanism 3 can suction the workpiece, and the two ends of the suction mechanism 3 can press the edges of the workpiece to assist in fixing. Then, the cutting mechanism 4 can be moved along the first direction 6 or the second direction 7 to cut the workpiece into a required shape. After cutting, the rotating mechanism 2 rotates the suction mechanism 3 below the cutting mechanism 4 to below the gluing mechanism 5, and the suction mechanism 3 originally below the gluing mechanism 5 is rotated to below the cutting mechanism 4, and the above steps can be repeated.

[0067] When the cut workpiece is rotated to below the gluing mechanism 5, the gluing mechanism 5 can be moved or lifted along the first direction 6, the second direction 7 or the third direction 8 to glue the cut workpiece on the suction mechanism 3. The glued workpiece can be taken out by manual operation or external equipment.

[0068] The rotating mechanism 2 and the double suction mechanism 3 can be designed to simultaneously perform the tab cutting and gluing processes, and no repositioning is required when the rotating position is switched, which greatly shortens the processing cycle and improves the production efficiency. The suction mechanism 3 can be lifted along the third direction 8 to press the workpiece, and the cutting mechanism 4 and the gluing mechanism 5 can be moved along the first direction 6 and the second direction 7 (such as X / Y axes) to realize multi-dimensional precise positioning of the tabs, ensure the cutting size accuracy and the gluing trajectory consistency, and reduce the manual intervention error. The cutting and gluing function modules are integrated in the same workbench 1, which is compact in structure, reduces the equipment floor area and material transfer links, and reduces the production cost.

[0069] In the embodiment, the middle part of the workbench 1 is provided with a sliding groove 201 which is arranged in a ring shape. The rotating mechanism 2 is slidably arranged on the sliding groove 201 and moves in a ring shape along the sliding groove 201.

When the two adsorption mechanisms 3 need to exchange positions, the rotating shaft 204 can be driven to rotate by motor 203. When the rotating shaft 204 rotates, it drives fixed plate 206 to rotate, and multiple sliding columns 207 also move in slide groove 201. Multiple sliding columns 207 play an auxiliary stabilizing role to ensure that fixed plate 206 does not shift when rotating.

[0071] In this embodiment, the adsorption mechanism 3 includes: a vacuum adsorption plate 301, which is disposed at one end of the fixed plate 206 and can be externally connected to a vacuum pump; two first air rods 302, which are vertically disposed on the fixed plate 206 and spaced apart on one side of the vacuum adsorption plate 301; two first pressure blocks 303, which are respectively disposed on the two first air rods 302; and two second air rods 304, which are vertically disposed on the fixed plate 206 and spaced apart on the other side of the vacuum adsorption plate 301. The two second air rods 304 are spaced apart; the two second pressure blocks 305 are respectively located on the two second air rods 304; when it is necessary to cut the workpiece, the worker or external equipment can place a whole plate of workpiece on the vacuum adsorption plate 301.

[0072] During the cutting process, a whole plate of workpieces can be cut into multiple small workpieces, and the vacuum adsorption plate 301 can adsorb and fix the cut small workpieces through its own tiny adsorption holes.

[0073] After the cutting is completed, the workpiece is rotated to below the gluing mechanism 5, and after the gluing mechanism 5 completes gluing of the workpiece, the vacuum pump stops working, and the two first air rods 302 and the two second air cylinders respectively drive the two first pressing blocks 303 and the two second pressing blocks 305 to rise in the third direction 8, so as to facilitate the staff or external equipment to take away the workpiece after the gluing is completed.
