Thus, the opening part of the head 34b is located at the top, arranges a plurality of battery packs 34, injects electrolyte into the open part of the head 34b, and then simply glues the open part with a jig to seal the finished product. Got.

However, in the battery pack as described above, although the electrolyte injected into the precursor 34b is a substance that is easily vaporized at room temperature, a certain amount of electrolyte is injected into the precursor 34b of the battery pack 34 in the ambient temperature. Since the open portion is simply pressed or welded using a jig, there is a problem in that the electrolyte solution in the precursor 34b is easily evaporated or air is penetrated into the electrolyte until the electrolyte solution in the precursor 34b is injected and completely sealed.

The battery pack 34 of the finished product obtained by sealing the roll 34b in a state in which air is penetrated into the electrolyte inside the roll 34b is fatal in that air acts as a foreign material in the electrolyte and degrades the performance or life of the battery. There was a problem.

The present invention is to solve the above problems, the object is to remove the air bubbles in the electrolyte by performing the sealing operation of the precursor in the chamber of the vacuum state, thereby extending the performance and life of the battery as well as the adhesion of the precursor A part also provides an adhesive device for a battery pack that is securely bonded.

On the upper surface of the plate material 31 of the lifting slider 30, a jig 33 capable of arranging and seating a plurality of battery packs 34 in at least one row is mounted.

The transfer device 40 has a forward / reverse rotation motor 41 mounted on the upper end of the chamber 20 and a screw 42 connected to the output rotation shaft thereof. The screw 42 has a center line direction according to the rotation direction thereof. The conveying bracket 43 which is conveyed by the is installed. The conveying bracket 43 is provided with a lifting body 45 through the adjusting screw 44 to enable height adjustment, and the lifting body 45 has a jaw operating part 46 for operating the bonding jaw 46a. Is installed.

The jaw operating part 46 is equipped with a cylinder 47 having a second rack 48 at the piston rod end and a second pinion 49 engaged with both sides of the second rack 48 of the cylinder 47. In the lower portion of the second pinion 49, a horizontal slider 50 is installed to move horizontally along the horizontal guide 51 by the third rack engaged with the horizontal pin 50, and the horizontal slider 50 has a heater 53. An adhesive jaw 46a is mounted.

The chamber 20 is provided with a vacuum generation line 60 for generating the inside of the vacuum to the vacuum generation line 60, the first valve through the suction line 61 to be distributed with the inside of the chamber 20 (62), the rapid vacuum pump 63 and the vacuum pump 64 is connected to the suction line 61 and the suction line 61 and the inlet position of the first valve 62 and the rapid vacuum pump 63 and the circulation The second valve 66 and the valve controller 67 are installed through the branch line 65 branched as much as possible.

In addition, one side of the chamber 20 is provided with a vacuum release line 70 for releasing the vacuum generated therein, the vacuum release line 70 is a third valve (71) to be distributed with the interior of the chamber 20 ) And a diffusion preventing device (72).

The diffusion preventer 72 is to form a myriad of fine holes to prevent the diffusion of air by delaying the release of the air suddenly when the external air is supplied to the chamber 20 in a vacuum state to prevent the generation of noise.

Although the vacuum release line 70 is illustrated and described as being installed in the chamber 20, the vacuum release line 70 may be installed in the slider 30.

The adhesive device of the battery pack according to the present invention configured as described above will be described with reference.

First, the power switch installed in the control unit 11 on the main body 20 is turned on and the vacuum pump 64 and the vacuum rapid pump 63 are operated, and at the same time, various devices such as the transfer device 40 Power is also applied to the heater 53 and the like.

In this state, a plurality of battery packs 34 seated on the jig 33 in the electrolyte charger are respectively seated on the plate 31 to which a certain amount of electrolyte is filled and transported, and then the driving motor 37 of the lifting mechanism. As it is driven while being raised to be in contact with the bottom of the chamber 20 is sealed. At this time, the lifting slider 30 is also stopped because the driving motor 37 of the lifting mechanism is stopped due to the signal of the upper limit sensor 38a mounted on one of the upright guides 32 of the lifting slider 30.

After the lower end of the chamber 20 is closed, the first valve 62 on the vacuum generation line 60 and the third valve 71 on the vacuum release line 70 are closed by the control unit 11. In addition to opening the second valve 66, the vacuum pump 64 and the vacuum rapid pump 63 are driven, thereby sucking the air in the chamber 20, and the inside thereof rapidly becomes a vacuum state. At this time, the vacuum pressure inside the chamber 20 is -550 to -750 mmHg and its internal temperature is 35 to 45 ° C.

As such, when the vacuum state is achieved, the first valve 62 is closed by the control unit 11 and only the second valve 66 is kept open, and the first valve 62 is opened by the valve controller 67 on the branch line 65. The opening and closing degree of the two valves 66 is controlled to maintain the inside of the chamber 20 at a predetermined vacuum pressure (-550 to -650 mmHg).

As such, as the inside of the chamber 20 is maintained at a predetermined vacuum pressure, bubbles in the electrolyte filled in the precursor 34b of the battery pack 34 are also removed. The feed bracket 43 is moved by starting to drive the reverse rotation motor 41 and rotating the screw 42 connected to the output rotation shaft of the forward / reverse rotation motor 41. In this way, the transfer bracket 43 starts to be transferred, and the adhesive jaw 46a thereof is stopped while coinciding with the battery pack 34 at one end of the battery pack 34 on the jig 33. That is, when the battery pack 34 is matched with the edge of the jig 33, the forward / reverse rotation motor 41 is stopped.

After the transfer bracket 43 is stopped in this manner, the cylinder 47 is operated to extend the piston rod and the second pinions 49 engaged with the second rack 48 at the end of the piston rod are interlocked and rotated. It is guided along the horizontal guide 51 by the third rack of the horizontal slider 50 engaged with the two pinions 49 and starts to move closer to each other.

As such, when the adhesive jaw 46a of the horizontal slider 50 moves close to each other and comes into contact with each other, the upper end portion of the head 34b of the battery pack 34 is positioned between the pair of bonding jaws 46a. Pressure and heat of the heater 53 inside the bonding jaw 46a are applied, and thus, the roll 34b, which is an open portion on the top of the battery pack 34, is reliably bonded.

After the precursor 34b of the battery pack 34 is adhered, the cylinder 47 is operated again and the piston rod is returned to its original position, so that the second pinions 49 are rotated in opposite directions. The bonding jaw 46a is also returned to the original position.

In this way, after the adhesion to one battery pack 34 is completed, the forward / reverse rotation motor 41 of the transfer device 40 is operated to move in the initial transfer direction by the interval of the battery pack 34 on the jig 33. And then stop. That is, from the battery pack 34 at the initial position where the bonding is completed, the battery pack 34 is moved from the battery pack 34 on the jig 33 adjacent to one side thereof.

As described above, the transfer device 40 is moved and the process of bonding the precursor 34b of the battery pack 34 is repeated several times to complete bonding to the battery pack 34 positioned at the edge on the jig 33. As the forward / reverse rotation motor 41 of the transfer device 40 is reversely rotated, the jaw operating unit 46 of the transfer device 40 is returned to its original position by the screw 42 which is rotated together with the output rotation shaft. .

When the battery pack 34 on the jig 33 positioned in the chamber 20 is bonded as described above, the vacuum is released while both the first valve 62 and the second valve 66 on the vacuum generation line 60 are locked. The vacuum in the chamber 20 is released by opening the third valve 71 on the line 70. At this time, the diffusion preventing device 72 of the vacuum release line 70 delays the vacuum in the chamber 20 to be suddenly released by a plurality of minute holes and prevents the rapid diffusion of air to release the vacuum without noise.

After the vacuum in the chamber 20 is released, the drive motor 37 constituting the lifting mechanism under the main body 10 is driven again, and the rack 35 engaged with the first pinion 36 on the drive motor 37 side is again driven. As) is lowered, the plate 31 of the lifting slider 30 is also lowered. At this time, the plate 31 of the lifting slider 30 is lowered along the upright guide 32 and lowered until the driving motor 37 is stopped by the lower limit sensor 38b.

After the plate 31 of the lifting slider 30 is lowered, the jig 33 on which the bonding operation of the battery pack 34 is completed is lifted and the new jig 33 on which the battery pack 34 to be worked is lifted. If the work is performed in the above-described order on the plate 31 of the slider 30, the continuous work is made.

As described in detail above, unlike the conventional art of gluing a battery pack's precursor by hand with a jig in a room temperature atmosphere, the bonding apparatus of the battery pack according to the present invention performs the sealing operation of the precursor in a vacuum chamber. Thus, bubbles in the electrolyte are completely removed, thereby extending the performance and life of the battery, as well as having a unique effect of reliably bonding the adhesive part of the precursor.
