The preferred embodiments of the utility model are shown in the drawings. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein.

[0045] As Figures 1 to 10 Indicated, the present embodiment provides a kind of rubberizing device of electric core, for the double-sided adhesive tape of electric core sticking, including:

[0048] Tensioning unit 3, is located in rack 1 and is below unwinding unit 2, for the double-sided adhesive tape of unwinding unit 2 is pulled out;

[0049] Die cutting unit 4, is located above die cutting table 11, for the double-sided adhesive tape of pulling out is cut;

[0050] The adhesive assembly 5 is used for attaching the cut double-sided adhesive on the battery cell, and the adhesive assembly 5 comprises an adhesive driving unit (not shown in the figure) and an adsorption unit 51 corresponding to each unwinding unit 2 for adsorbing the cut double-sided adhesive. The adsorption unit 51 is located above the die cutting table 11, and the adhesive driving unit can drive the adsorption unit 51 to lower and translate to adsorb the cut double-sided adhesive, so as to separate the cut double-sided adhesive from the release paper. In this embodiment, two adsorption units 51 are provided, corresponding to two unwinding units 2, and the die cutting unit 4 simultaneously cuts two groups of double-sided adhesive. The adsorption unit 51 simultaneously adsorbs the two double-sided adhesive and moves to the position of the battery cell for adhesive attachment. Alternatively, the adhesive driving unit can be of the prior art, which can be a horizontal moving module or a mechanical arm, as long as it can realize horizontal and vertical movement.

[0051] The distribution unit 6 is arranged adjacent to the end of the die cutting table 11 away from the die cutting unit 4, and a passage for the release paper to pass through is formed between the distribution unit 6 and the die cutting table 11. The distribution unit 6 is used to separate the double-sided adhesive of the front and rear sections of the cut double-sided adhesive.

[0052] The battery cell adhesive device of the embodiment can be movably arranged beside the battery cell conveying line. After the double-sided adhesive is adsorbed by the adsorption unit 51, it is moved to the upper side of the battery cell to be attached with adhesive, and then the double-sided adhesive is pressed and attached on the battery cell. Specifically, the release paper of the two groups of double-sided adhesive is pulled by the pulling unit 3 at the same time, and a fixed length of double-sided adhesive is pulled out from the unwinding unit 2 each time. The cut double-sided adhesive is laid on the die cutting table 11, and the side with the release paper is attached to the die cutting table 11. The die cutting unit 4 cuts the fixed length of double-sided adhesive, and the release paper is not cut off. Then, the adsorption unit 51 is driven by the adhesive driving unit to move to the upper side of the double-sided adhesive, and then lower to adsorb the double-sided adhesive.
