and a roller unit continuously moving in at least one direction of the accommodating portion and the sealing portion and adhering the adhesive member supported by the support unit to the secondary battery cell. ## Claims ### Claim 1 A taping apparatus for a secondary battery, configured to adhere an adhesive member cut and provided as a single sheet to a secondary battery cell including an accommodating portion in which an electrode assembly is accommodated and a sealing portion folded in a direction of the accommodating portion and sealing an edge of the accommodating portion, comprising: a support unit supporting a portion of the adhesive member; and a roller unit continuously moving in at least one direction of the accommodating portion and the sealing portion and adhering the adhesive member supported by the support unit to the secondary battery cell, wherein the support unit comprises: an adsorption temporary adhering unit adsorbing the adhesive member to move in a direction of the secondary battery cell, and adhering a portion of the adhesive member to the secondary battery cell; wherein the adsorption temporary adhering unit comprises: a temporary adhering head having a negative pressure flow path formed on one surface of the adhesive member and connected to an external negative pressure forming portion; wherein the negative pressure flow path is formed on one surface of the temporary adhering head contacting the adhesive member, formed to have a radial shape, and formed to communicate with each other, wherein the radial shape is formed by lines on the one surface of the temporary adhering head, and wherein the temporary adhering head is formed to have a concave shape on the one surface of the temporary adhering head. ### Claim 2 (depends on 1) The taping apparatus of claim 1, wherein the roller unit comprises: a first multi-roller moving while closely pressing the adhesive member in a direction of one surface of the accommodating portion; and a second multi-roller moving while closely pressing the adhesive member in a direction of the other surface of the accommodating portion. ### Claim 3 (depends on 1) The taping apparatus of claim 1, wherein the roller unit comprises a single roller moving while closely pressing the adhesive member adhered to and supported on one surface of the accommodating portion by the support unit, in a direction of the sealing portion and in a direction of the other surface of the accommodating portion. ### Claim 4 (depends on 1) The taping apparatus of claim 1, wherein the support unit comprises: a fully adhering supporter disposed to be spaced apart from the adsorption temporary adhering unit by a predetermined distance and provided adjacent to the roller unit. ### Claim 5 (depends on 4) The taping apparatus of claim 4, wherein the adsorption temporary adhering unit comprises: a temporary adhering cylinder coupled to the temporary adhering head and moving the temporary adhering head in a direction of the secondary battery cell. ### Claim 6 (depends on 5) The taping apparatus of claim 5, wherein the temporary adhering head comprises a discharge terminal connected to a ground and provided on the one surface of the temporary adhering head with which the adhesive member is in contact, to discharge electrostatic charges of the adhesive member to the ground. ### Claim 7 (depends on 5) The taping apparatus of claim 5, wherein the temporary adhering cylinder elastically pressurizes the temporary adhering head in the direction of the secondary battery cell. ### Claim 8 (depends on 4) The taping apparatus of claim 4, wherein the fully adhering supporter comprises: a support head in close contact with a portion of the adhesive member attached to the secondary battery cell by the adsorption temporary adhering unit; and a support cylinder coupled to the support head and pressurizing the support head in the direction of the secondary battery cell. ### Claim 9 (depends on 8) The taping apparatus of claim 8, wherein the support cylinder elastically pressurizes the support head in the direction of the secondary battery cell. ### Claim 10 (depends on 8) The taping apparatus of claim 8, wherein the support head comprises a support block formed of a urethane material or a sponge material. ### Claim 11 (depends on 8) The taping apparatus of claim 8, wherein the support head comprises: a support frame coupled to the support cylinder; and a plurality of support fingers provided on the support frame and elastically pressurized in an outward direction. ### Claim 12 (depends on 1) The taping apparatus of claim 1, wherein the support unit comprises an adsorption supporter adsorbing the adhesive member to move in a direction of the secondary battery cell, and supporting in a state in which a portion of the adhesive member is pressurized in the direction of the secondary battery cell to be adhered to the secondary battery cell, while the roller unit closely presses the adhesive member against the secondary battery cell.
