Process of doing; Taking a battery pack from a carrier jig; And enclosing the outer surface of the battery pack with an outer film having a barcode printed on the outer surface, wherein the battery cell moving device comprises a carrier jig and a die having grooves formed on one outer surface thereof. It is about.

With the development of technology and increasing demand for mobile devices, the demand for secondary batteries is also rapidly increasing. Among them, lithium secondary batteries with high energy density, high operating voltage, and excellent storage and life characteristics are used for various mobile devices as well as various electronic products. It is widely used as an energy source.

However, the lithium secondary battery contains various combustible materials, and there is a danger of overheating or explosion due to overcharging, overcurrent, other physical external impact, etc., and thus has a serious safety drawback. Therefore, a lithium secondary battery is a safety device capable of effectively controlling abnormal conditions such as overcharge and overcurrent, such that a PTC (Positive Temperature Coefficient) element and a protection circuit module (PCM) are connected to the battery cell. It is mounted.

In general, PCM and the like are connected to the battery cell by a welding method via a conductive nickel plate. In other words, the nickel plate is welded to the electrode tab of the PCM, and then the nickel plate is connected to the electrode terminal of the battery cell, respectively, to connect the PCM to the battery cell to manufacture a battery pack.

These safety devices, including PCM, must maintain electrical connection with the electrode terminals while maintaining electrical isolation from other parts of the battery cell.

On the other hand, the operation of coupling a component such as a protective circuit member such as PCM to the top of the battery cell is performed in the battery pack assembly line. The configuration of the assembly line may vary depending on necessity, but is generally composed of a line that sequentially performs the mounting process of the metal clad, insulating mounting member, protective circuit module, and the insulating top cap.

However, since many of the above processes are performed manually, a large number of workers are required, and thus, a manufacturing cost of the battery is increased. Therefore, as a more advanced method, a method of performing a welding operation by mounting a plurality of battery cells in a predetermined device and then moving it to a welding device has been developed.

However, in order to sequentially perform a welding operation on a plurality of battery cells mounted in the apparatus, an operator needs to move the battery cell mounting apparatus at regular intervals, and therefore, there is a problem that skilled skills are required. Is one of the major constraints in automating the manufacturing process. On the other hand, a method of automating the sequential transfer of the battery cell to the welding device by a step motor, etc. can also be considered. In this case, there is a problem in that an expensive device for automation is provided.

In addition, although the process of applying the adhesive when the insulating mounting member and the battery cell top surface and the insulating top cap and the battery cell are combined is an important process for assembly quality, the work is performed by manual, There is a problem that a lot of assembly failure due to the deviation.

Therefore, there is a high need for a technology that can solve the above problems, and configure a simple and easy assembly line to improve the manufacturing processability and productivity of the battery pack.

The present invention aims to solve the above-mentioned problems of the prior art and technical problems that have been requested from the past.

Specifically, an object of the present invention is to provide a battery pack manufacturing method capable of automating adhesive coating, exterior film attachment, and the pressing process so that the assembly quality of the battery pack is improved.

Still another object of the present invention is to provide a battery pack manufacturing method using a battery cell moving device having a structure capable of performing a predetermined continuous operation by forming a carrier jig and a die in a specific structure.

Method for manufacturing a battery pack according to the present invention for achieving this object, as a method for manufacturing a battery pack in a continuous operation for a plurality of battery cells using a battery cell moving device,

(a) mounting an insulating bottom cap on the bottom surface of the battery cell and mounting it on a carrier jig of the battery cell moving device;

(b) placing the metal clad on the top surface of the battery cell, and then joining the metal clad and the top surface of the battery cell by welding;

(c) Applying an adhesive to the lower surface of the insulating mounting member or the upper surface of the battery cell and placing the insulating mounting member on the upper surface of the battery cell, and then press the upper end of the insulating mounting member with a pressure device, the insulating mounting member and Combining the top surface of the battery cell;

(d) placing the protective circuit module on the upper surface of the insulating mounting member and then welding the protective circuit module and the battery cell with a welding device to make an electrical connection;

(e) Apply adhesive to the upper surface of the protective circuit module or the inner surface of the insulating upper cap, place the insulating upper cap on the upper part of the protective circuit module, and press the upper end of the insulating upper cap with a pressure device to insulate the insulating upper cap and the battery. Joining cells;

(f) taking the battery pack from the carrier jig; And

(g) a process of wrapping the outer surface of the battery pack with an outer film having a barcode printed on the outer surface thereof;

To include, the battery cell moving device,

It has a rectangular structure with an open top, and has mounting grooves formed on an inner surface thereof so that a plurality of battery cells can be mounted upright at regular intervals with an electrode terminal exposed to the upper side, and one side at the battery cell mounting intervals. A carrier jig having grooves formed on an outer surface thereof; And an elastic pressing member for elastically pressing the opposite surface of the outer surface on which the groove of the carrier jig is formed, and a series of coupling grooves are formed on a surface corresponding to the groove so that the groove of the carrier jig can be elastically engaged. The die consisting of an elastic coupling member;

Therefore, the battery pack manufacturing method according to the present invention, since the bonding of the insulating mounting member and the top surface of the battery cell, and the bonding of the insulating top cap and the battery cell after applying the adhesive and press the pressure device to combine the respective members, By assembling each other, the assembly quality of the battery pack can be greatly improved.

In addition, since the battery cell moving device according to the present invention can continuously perform welding or mechanical fastening for joining parts on the upper part of the battery cell using a carrier jig, a continuous process by automation or semi-automation is possible. . In particular, in order to lower the manufacturing cost, an automation system composed of a small investment cost can be preferably used for the manufacture of a battery pack.

For reference, the process (b) of joining the upper surface of the metal clad and the battery cell by welding may be selectively used as necessary, so that the process (b) may be excluded from the battery pack manufacturing method according to the present invention. .

When the insulating mounting member and the top surface of the battery cell are coupled, and the adhesive is applied when the insulating top cap is coupled with the battery cell, the pressing and mounting of the respective members are processes that generate a lot of defects, as mentioned above. In addition, it is an important process in securing assembly quality of battery pack. Therefore, it is desirable to automate the adhesive application and compression process in order to ensure the excellent quality of the battery pack.

In one preferred example, the adhesive can be configured to be applied automatically by an automatic bonding dispenser, so that the bonding operation can be carried out continuously and precisely, which can improve productivity and quality by automation. Existing battery pack manufacturing line has a difficulty in automating the overall manufacturing process of the battery pack by not using the automatic bonding dispenser.

This automatic bonding dispenser enables the application of the adhesive to a large number of areas automatically when applying the adhesive to a predetermined site, and thus is effective in manufacturing lines requiring precision and mass production, such as battery pack manufacturing lines. .

In addition, in the case of using the automatic bonding dispenser, it is possible to enhance the adhesive strength by varying the application method according to the characteristics of the member to be bonded, for example, in the bonding operation of the insulating mounting member by applying an adhesive through a point attachment method The bonding operation of the insulating top cap may be configured to apply an adhesive by applying a line attachment method.

The pressing process is an important process for improving the assembly quality of the battery pack together with the adhesive coating process as mentioned above. That is, when the crimping operation is performed for a time shorter than a predetermined time according to the battery pack manufacturing specifications, it may be difficult to secure the desired bonding force, and when the time is performed for longer than the predetermined time, the efficiency of the process may be reduced and the possibility of leakage of the adhesive may be reduced. Therefore, it is not preferable. Therefore, the pressurizing device may have a structure in which a timer is mounted to perform the pressing for a predetermined time.

The crimping process may be performed for each battery cell using a plurality of pressurizing devices, but performing a process for a plurality of battery cells using a single pressurizing device reduces manufacturing lead time. More preferred.

For example, in the crimping process, the crimping unit may be installed by setting an optimal crimping time after bonding of the insulating mounting member and bonding of the upper cap of the insulator phase, which affect the adhesion and the overall dimensions, and a timer in the crimping unit. It can be configured to automatically discharge after pressing for a predetermined time by installing.

When the battery cell moving device presses the carrier jig in the advancing direction while the carrier jig is mounted between the elastic pressing member and the elastic coupling member of the die, the carrier jig is elastically pressed by the elastic pressing member of the die. While moving by one step along the elastic coupling member at intervals of groove formation, it is possible to continuously perform a predetermined operation on the battery cells mounted on the carrier jig.

Therefore, the battery cell moving device has a structure in which the battery cells are continuously moved in the advancing direction by one step while the battery cells are mounted on the carrier jig, and thus, the battery cell moving device can be operated at a lower cost than when an automatic transfer device such as a step motor is used. The automation line can be easily implemented, and the manufacturing cost of the battery can be greatly reduced.

As one example, the carrier jig may have a structure in which at least one side of four sides of the side surface is detachable to facilitate mounting of the battery cells to the carrier jig.

This structure allows the battery cells to be mounted in the mounting grooves of the carrier jig in the lateral direction with one side of the carrier jig removed, so that when the battery cells are mounted in the mounting grooves of the carrier jig downwards from the top of the carrier jig. In comparison, the mounting time can be greatly reduced.

In addition, the detachable structure of the carrier jig can be used in a state in which one side of the carrier jig is selectively opened or closed as necessary, which is also preferable in terms of maintenance to repair or repair the inside of the carrier jig.

In the above structure, the carrier jig may be formed of a carrier jig main body having one side open and a detachable member detachable to one open side of the carrier jig main body.

Therefore, a magnetic force member such as a magnet is installed at the detachable portion of the carrier jig, so that at least one side of the carrier jig can be more easily separated and combined with the remaining sides.

On the other hand, the elastic pressing member is preferably equipped with a compression spring, while providing a resilient pressing force to the carrier jig, the carrier jig mounted between the elastic pressing member and the elastic coupling member is in place by an external force such as vibration. Deviation from can be prevented.

As another example, the carrier jig may be moved automatically, semi-automatically or manually in the direction of progress for the continuous operation, and may be selectively set as required.

That is, the carrier jig is configured to move by being pressed by the cylinder, it can move automatically or semi-automatically in the advancing direction. The cylinder may be classified into an air cylinder and a hydraulic cylinder according to the type of fluid. In general, the cylinder is preferable because the air cylinder is inexpensive compared to the hydraulic cylinder.

For example, when the air cylinder applies a constant pressure in the direction of travel of the carrier jig, as mentioned above, the carrier jig has a resilient pressing force of the elastic pressing member, interfacial friction force of the groove and the engaging groove, and pressure of the air cylinder. And so by physical interaction, it is possible to continuously move by one step in the advancing direction along the elastic coupling member at the groove formation intervals.

On the other hand, the continuous operation is a welding operation for attaching the metal clad on the top surface of the battery cell, bonding and pressing operation for coupling the insulating mounting member to the electrode terminal of the battery cell, the insulating mounting member is coupled to the top of the battery cell Welding to electrically connect the protection circuit module to the battery cell, and bonding and crimping to combine the protection circuit module and the insulating top cap while the protection circuit module is coupled to the insulating mounting member on the top of the battery cell. It may consist of one task selected from the group.

That is, the continuous operation is not particularly limited as long as the operation is performed on the battery cell, and may be performed in various kinds of operations, and may be one of several operations for coupling a part to the upper part of the battery cell. In the above operation, the coupling may be performed by various methods such as bonding, fitting, fastening, welding, and the like.

(a2) attaching a double-sided tape to the bottom surface of the battery cell;

(a3) attaching the battery cell to the carrier jig with the electrode terminal exposed in an upward direction to couple the bottom surface of the battery cell to the insulating bottom cap; And

(a4) repeating steps (a1) to (a3) by moving the carrier jig one step forward (or backward);

Can be made.

 In other words, after attaching the insulating lower cap of the battery cell to the mounting groove of the carrier jig, attach double-sided tape to the lower surface of the insulating phase, and mount the battery cells in the carrier jig with the electrode terminal exposed in the upper direction, the battery cell After the bottom surface and the insulating bottom cap is coupled, the coupling of the insulating bottom cap and the bottom surface of the battery cell can be continuously achieved while moving the carrier jig in one direction.

In a specific example, the process (b),

(b1) attaching a metal clad mounting cover having a plurality of through holes formed on the upper end of the carrier jig;

(b2) placing the metal clad on the top surface of the battery cell electrode terminal through the through hole of the metal clad mounting cover;

(b3) welding the metal clad downwardly from the top by a welding device to couple the metal clad to the battery cell electrode terminals; And

(b4) repeating step (b3) by moving the carrier jig one step forward (or backward);

Can be made.

That is, in the welding operation of the metal clad as described above, the metal clad mounting cover is additionally mounted on the upper part of the carrier jig, and the metal clad mounting cover is welded to the upper end of the metal clad mounted on the battery cells. Through holes may be formed that are exposed toward the welding device.

Specifically, a metal clad mounting cover having a plurality of through holes formed thereon is mounted on an upper end of a carrier jig, and a metal clad is placed on an upper end surface of a battery cell electrode terminal through the through hole, and then a welding device is attached to the welding device. The metal clad is welded downward from the top to thereby couple the metal clad to the battery cell electrode terminal, and the carrier jig is moved in the advancing direction step by step, thereby continuously welding the metal clad and the battery cell electrode terminal. have.

Therefore, with the structure in which the through holes are formed in the metal clad mounting cover as described above, the welding device can weld the upper welding portion of the metal clad through the through hole from the top of the metal clad mounting cover, and the welding device is made of metal. It can be accurately guided to the upper welding portion of the clad, it is possible to fundamentally prevent the possibility of damage to other parts during the welding process of the battery cell electrode terminal and the metal clad. For example, a welding operation for mutually coupling the metal clad and the electrode terminal located on the top surface of the battery cell may be accomplished by spot welding.

In a specific example, the process (c),

(c1) removing the metal clad mounting cover from the carrier jig and mounting the insulating mounting member mounting cover on the upper end of the carrier jig in which a plurality of through holes corresponding to the outer circumferential shape of the insulating mounting member are formed;

(c2) applying an adhesive to the top surface of the battery cell or the bottom surface of the insulating mounting member in a point-adhesive manner;

 (c3) placing the insulating mounting member in the through hole of the cover for mounting the insulating mounting member;

 (c4) pressing the insulating mounting member downward by a pressing device to couple the insulating mounting member to the top of the battery cell; And

(c5) repeating the step (c4) by moving the carrier jig one step forward (or backward);

It may be configured as.

In this manner, an insulating mounting member mounting cover may be additionally mounted on an upper portion of the carrier jig, and through holes corresponding to the outer circumferential surface shape of the insulating mounting member may be formed in the insulating mounting member mounting cover.

Apply with Thereafter, the insulating mounting member may be inserted into the through holes, and the upper portion of the insulating mounting member may be pressed downward by the pressing device, thereby firmly coupling the upper end of the battery cell and the insulating mounting member. Thereafter, while the carrier jig is moved in the advancing direction by one step, the coupling between the top surface of the battery cell and the bottom surface of the insulating mounting member may be continuously achieved.

The through holes are formed in a structure corresponding to the outer circumferential surface of the insulating mounting member, and thus can prevent the insulated mounting member from being displaced in position during the coupling process between the insulating mounting member and the top cap of the battery cell.

In addition, the process of coupling the lower surface of the insulating mounting member and the upper surface of the battery cell may be selectively applied according to the bonding method, it is preferable to apply by applying a point attachment method. Therefore, the bonding operation for coupling the insulating mounting member and the top surface of the battery cell can be carried out accurately and safely, and the adhesion of the adhesive can be improved, and the bonding can be performed with enhanced adhesive force.

In a specific example, the process (d),

(d1) removing the insulating mounting member mounting cover from the carrier jig, and mounting the protective circuit module mounting cover on the upper end of the carrier jig in which a plurality of through holes corresponding to the outer circumferential surface of the protective circuit module are formed;

By welding to the connection terminal of the protective circuit module through the mutual coupling can be easily achieved. In addition, the coupling of the insulating mounting member and the protective circuit module can be continuously achieved while moving the carrier jig step by step in the advancing direction.

Since the through holes have a structure corresponding to the shape of the outer circumferential surface of the protective circuit module, the through holes may be prevented from being displaced from the protective circuit module in a correct position which may occur during the coupling process between the insulating mounting member and the protective circuit module.

In a specific example, the process (e),

(e1) removing the protective circuit module mounting cover from the carrier jig, and mounting the insulating top cap mounting cover having a plurality of through holes corresponding to the outer circumferential shape of the insulating top cap on the carrier jig;
