Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be discussed further in subsequent figures.

As shown in fig. 1 to 4, the cell adhesive paper activation jig of the present embodiment includes: a base 10, a first roller 20, a carriage 30, a second roller 40 and a tensioning structure 50. Wherein, the first roller 20 is rotatably arranged on the base 10, and the axis of the first roller 20 is fixed relative to the base 10; the carriage 30 is slidably disposed on the base 10; the second roller 40 is rotatably arranged on the sliding frame 30, and the axis of the second roller 40 is parallel to the axis of the first roller 20; a tensioning arrangement 50 is connected between the base 10 and the carriage 30 to return the second roller 40 to an initial position adjacent the first roller 20.

By applying the technical scheme of the embodiment, the battery cell gummed paper activation jig comprises a base 10, and a first roller 20 and a second roller 40 which are arranged on the base 10, wherein the first roller 20 is rotatably arranged on the base 10, and the axis of the first roller 20 is fixed relative to the base 10; the second roller 40 is rotatably disposed on the sliding frame 30 capable of sliding relative to the base 10, and the position of the axis of the second roller 40 relative to the sliding frame 30 is fixed, i.e., the second roller 40 is slidably disposed relative to the first roller 20. The tensioning structure 50 is connected between the base 10 and the carriage 30 to apply a tensioning force to the carriage 30, and the carriage 30 and the second roller 40 disposed on the carriage 30 are maintained at an initial position close to the first roller 20 under the tensioning force of the tensioning structure 50 in the absence of an external force. When the adhesive tape is activated, an operator only needs to push the battery cell between the first roller 20 and the second roller 40, and the battery cell applies ejection force to the first roller 20 and the second roller 40 and overcomes the tension force of the tension structure 50 to move the second roller 40 in a direction away from the first roller 20, so that the battery cell is clamped between the first roller 20 and the second roller. With the continuous advance of the battery cell, the acting force (i.e. the pressure for activating the adhesive tape) of the first roller 20 and the second roller 40 on the surface of the battery cell is kept unchanged, the acting force mainly depends on the magnitude of the tension force, the operator can adjust the acting force in advance, and the acting force uniformly acts on the adhesive tape when activating the adhesive tape subsequently, so that the adhesive property of the adhesive tape can be effectively activated.

The connecting film 60 is arranged on the outer sides of the first roller 20 and the second roller 40, and when the adhesive tape is activated, the connecting film 60 is in contact with the outer surface of the adhesive tape, so that the adhesive tape can be isolated from the outer surfaces of the first roller 20 and the second roller 40, and the adhesive tape is prevented from being scratched. Specifically, in the present embodiment, the connection film 60 is made of teflon, and the surface thereof is smooth, so that the connection film can adapt to different adhesive paper surfaces, and effectively prevent the adhesive paper surfaces from being scratched during the pressing process to leave scratches. Meanwhile, the connection film 60 is always supported below the battery cell, and the battery cell can be prevented from falling below the first roller 20 and the second roller 40.

When pasting the adhesive tape, glue the adhesive tape at the front, the back and the side position of electric core respectively, because the adhesive tape that is located electric core side position department is less with the overlapping area who is located electric core front and back adhesive tape, it is also especially important to activate the adhesive tape that is located electric core side position. The activation method in the related art cannot effectively activate the gummed paper at the round corner of the side edge position of the battery core. The battery core gummed paper activation jig of this embodiment can also activate the gummed paper that is located battery core side fillet position department effectively, specifically, when impelling between first cylinder 20 and second cylinder 40 with battery core, first cylinder 20 and second cylinder 40 can be at first to the side of battery core and the pressurization of battery core side fillet position department, along with impelling deepening to the front and back surface pressurization of battery core again.
