Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for attaching an insulating tape to an end of a battery cell, and more particularly to an apparatus for attaching an insulating tape to an end of a battery cell, To an attachment device.

In general, a process of attaching an insulating tape to an end of a battery cell is performed before the battery cell case is fully assembled after completing an electrode welding operation on a battery in a line for manufacturing an electric vehicle battery cell.

That is, a battery to be applied to an electric vehicle must have a large capacity, so that a plurality of battery cells are assembled into a single module form, so that a module shape requires insulation between the end portions of the battery cells in which the electrode leads are exposed, It is necessary to attach an insulating tape to the outside of the end portion of the battery cell in order to insulate between the end portions.

The work of attaching the protective insulating tape to the upper and lower surfaces of the electrode lead welded to the battery cell and exposed to the one end is manually performed by the operator manually after welding the electrode lead to the battery cell in the battery cell manufacturing line Process.

The operator cuts a predetermined size of the insulating tape from the insulating tape supply device, attaches the supplied insulating tape to the upper surface of the end portion of the battery cell, manually attaches the insulating tape to the lower surface of the battery cell, and completes the process of attaching the insulating tape.

However, since the operation of attaching the insulating tape to the battery cell in the related art is performed manually by an operator, there is a high possibility that the insulating tape adhered to both sides of the battery cell is weakened and dropped, Respectively.

In addition, since the attaching process is performed manually by the operator, the work time is relatively long compared to the welding of the electrode leads, so that the work productivity is lowered and the work load of the worker is increased.
