Description

Automated Finishing Process Apparatus for Battery Cell}

The present invention relates to an automated battery cell finishing process device.

Recently, secondary batteries capable of charging and discharging have been widely used as an energy source for wireless mobile devices.

The secondary battery may be used in the form of a single battery or a battery pack in which a plurality of unit cells are electrically connected depending on the type of external device used. For example, a small device such as a mobile phone can operate for a predetermined period of time with the output and capacity of one battery, while a medium sized device such as a notebook computer, portable DVD, small PC, electric vehicle, hybrid electric vehicle, etc. Large devices require the use of battery packs due to issues of output and capacity.

On the outer surface of the battery cell and the inner or outer surface of the battery pack, various information such as manufacturer, model name, product number, various standards or quality indications, and precautions for use are displayed in the form of letters or marks. Such information may be displayed in a pre-printed form on the external case of the battery, but when the battery pack is mounted on an external device such as a mobile phone or notebook computer, a label sticker printed with this information is attached to the outer surface of the completed battery pack. In some cases, an adhesive tape is used to attach the label sticker.

In addition, when one protective circuit member is mounted for a plurality of combined battery cells to form one battery pack, battery cells having substantially the same structure and shape are closely attached to each other, and the battery cells As a method of bonding the liver, a double-sided adhesive tape may be used.

In addition, when a battery pack is manufactured using one battery cell, a battery pack is formed by stably fixing the battery cell on one side or using an adhesive tape when attaching the battery cell to the pack case.

In this regard, referring to FIG. 1, the battery pack includes a pouch-type battery body 10 in which an electrode assembly of a positive electrode, a negative electrode, and a separator, and an electrolyte are sealed, and an internal space capable of accommodating the battery body 10. It is composed of a lower case 20 having the battery body 10 and an upper case 30 which is coupled to the lower case 20 in which the battery body 10 is accommodated to seal the battery body 10. In addition, a double-sided adhesive tape 40 is interposed between the battery body 10 and the upper and lower cases 20 and 30 so that the battery body 10 may be stably fixed to the inner space of the cases 20 and 30.

Moreover, the adhesive tape is also used when an insulating lower cap is additionally mounted by attaching a double-sided adhesive tape to the lower end of the battery cell.

In order to attach such a tape to the outer surface of the battery cell or the outer surface or the inner surface of the battery pack case, it takes a lot of work time and personnel to attach the tape cut to a certain size by directly peeling it from the release paper and attaching it to the corresponding part. Moreover, in the case of attempting to peel off a thin tape of 50 μm or less, there is a problem that it cannot be peeled off by a method using a commonly used peeling knife.

Therefore, even a very thin tape can be peeled off and attached with an automated device, and there is a high need for a tape attaching device with improved productivity and improved cost reduction by reducing work time and adhesion failure through the automated device.

An object of the present invention is to solve the problems of the prior art and technical problems that have been requested from the past.

Specifically, it is an object of the present invention to provide a battery cell finishing process apparatus capable of automating the entire battery cell finishing process such as tape attachment.

The process apparatus according to the present invention for achieving this object,

As a process device for closing the manufactured battery cells in a shipping state,

A cell handling unit configured to adsorb and fix the battery cells in close contact with the surface of the battery cells, and move the fixed battery cells up and down and left and right; And

A supply unit for supplying the insulating finishing material to a location of the battery cell fixed to the cell handling unit so that the insulating finishing material is added to the surface of the battery cell;

Contains,

The supply unit supplies an insulating finishing material to face the battery cell,

In a state in which the insulating finishing material and the battery cell face each other, the cell handling unit is moved so that the battery cell is in close contact with the insulating finishing material while operating to add the insulating finishing material to the surface of the battery cell.

That is, the process apparatus according to the present invention is configured to operate organically in the supply unit and the cell handling unit to automatically add the finishing material to the surface of the battery cell, so that the manpower input to the finishing process can be minimized, and accordingly Process efficiency can be provided.

Hereinafter, a specific structure of the process apparatus according to the present invention will be described in more detail through non-limiting examples.

In one specific example, the supply unit,

A sheet supply unit for continuously supplying an insulating finishing material sheet attached together with an adhesive on the release paper;

A cutting jig for cutting only the insulating finishing material excluding the release paper from the finishing material sheet to a predetermined size; And

Includes; a release paper winding unit for winding only the release paper remaining while the cut insulating finishing material is added to the battery cell,

When the cell handling part is in close contact with the cut insulating finishing material, the insulating finishing material is attached to the surface of the battery cell together with an adhesive and the insulating finishing material is separated from the release paper.

Here, the supply unit may operate to continuously supply the cut insulating finishing materials to a portion adjacent to the battery cell when the finishing material sheet moves from the sheet supply unit toward the release paper winding unit.

In connection with this, when the insulating finishing materials are positioned adjacent to the battery cell, the cell handling unit may add the insulating finishing material to the surface of the battery cell while moving so that the battery cell is in close contact with the insulating finishing material.

Accordingly, in the process apparatus according to the present invention, in attaching the finishing material sheet to the outer surface of the battery cell, it is possible to improve an inefficient method in which the operator directly peels and attaches the tape from the release paper as in the prior art.

In addition, compared to the manpower, uniformity of the attachment area of the finishing material sheet can be achieved through a series of processes by the supply unit, and the finishing treatment near the bonding boundary can be improved, thus reducing adhesion failures to improve productivity, and manufacturing The cost can be greatly reduced.

In the present invention, the insulating finish sheet may have a structure in which a pressure-sensitive adhesive is added to one surface facing the release paper and an opposite surface opposite to the one surface.

The insulating finish is an insulating pad having a thickness of 1 to 30 millimeters, or an insulating film having a thickness of 10 to 999 micrometers;

The insulating pad or film may be a double-sided adhesive member to which an adhesive is added to both sides.

According to the inventors of the present invention, when the compression film was not added, the battery cell was separated from the adsorption part in the process of moving the battery cell, and accordingly, it was confirmed that the compressed film was essential to move the battery cell in various directions. .

This is because the compressed film provides a higher frictional force between the vacuum pad and the surface of the battery cell, enabling close contact between them and preventing the sliding of the battery cell, thereby preventing the inertia or gravity applied during the movement of the battery cell from the adsorption unit. It can be understood that the battery cell is prevented from being separated.
