It should be noted that the present embodiment further provides an automatic belt splicing device 20, please refer to fig. 5, and fig. 5 shows a specific structure of the automatic belt splicing device 20.
Compared with the automatic tape splicing device 10, the automatic tape splicing device 20 further comprises a first unwinding mechanism 21, a second unwinding mechanism 22 and the automatic tape splicing device 10 provided above. The first unwinding mechanism 21 and the second unwinding mechanism 22 are respectively disposed on the mounting plate 11.
Fig. 5 shows the new tape 20a and the old tape 20b, and also shows the new tape 20a and the old tape 20b, and the way the tapes are threaded after splicing.
After the first unwinding mechanism 21 and the second unwinding mechanism 22 are installed on the mounting plate 11, the new material belt 20a or the old material belt 20b can be unwound respectively, the new material belt 20a and the old material belt 20b are threaded through the first roller set 15 and the second roller set, the front end of the new material belt 20a is clamped to the new material clamping mechanism 14 (here, the action is not shown in fig. 4), and the free end of the new material belt 20a is cut by the cutter 90 in the new material clamping mechanism 14. The new and old material strips 20b are heat-fused at the heat-fusing mechanism 12. The old material cutting mechanism 13 then cuts the old material tape 20b, completing splicing.
It should be noted that the first unwinding mechanism 21 and the second unwinding mechanism 22 are both unwinding devices for unwinding, and each unwinding device includes an unwinding shaft, a motor for driving the unwinding shaft to rotate, and an expansion structure for clamping the material tape, and the expansion mechanism is driven by an air cylinder to expand or retract to clamp or separate the material tape.
Based on the automatic tape splicing device 10, the automatic tape splicing device 20 can solve the problems that when the existing automatic tape splicing mechanism carries out new and old material roll splicing, the efficiency of a machine is reduced, the labor cost is increased and the quality of a battery cell is influenced due to manual glue preparation.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
