When the pickup robot 363 raises the cell body 1, both sides of the label sheet 41 of the cell body 1 are bent downward by contacting the pair of attachment rollers 351 as shown in FIG. 10A. do. In this case, the pair of attachment rollers 351 presses both sides of the cell body 1 by the elastic force of the elastic member 352. Thus, the label sheet 41 is attached to the side of the label sheet 1 while being pulled to both sides of the cell body (1). At the same time, both side portions of the label sheet 41 are bent downward.

When the label sheet attachment robot 360 is transported to one side (left side) along the Z-axis direction as shown in FIG. 10B, the bent one side portion of the label sheet 41 is pressed by one attachment roller 351. Accordingly attached to the cell body (1). In addition, when the label sheet attachment robot 360 is transferred to the other side (right side) along the Z direction as shown in FIG. 10C, the bent other side portion of the label sheet 41 is pressed by the remaining attachment roller 351. It is attached to the cell body (1). At this time, the bent portion of the label sheet 41 is attached to the central side from both sides of the cell body 1, the adhesion of the label sheet 41 is improved and the surface is smooth. By this process, the label sheet 41 is entirely attached to the outer surface of the cell body 1.

Referring to FIG. 11, when the attachment of the label sheet 41 is completed, the label sheet attachment robot 360 is transferred to one side along the Z-axis direction. In addition, the bot 360 attaches the cell body 1 to the seating panel 431 of the second transfer module 430.

The seating panel 431 is transferred in the Z-axis direction by the pneumatic cylinder 432 of the second transfer module 430. At this time, the function test unit 440 is to test the function of the cell body (1). The seating panel 431 is transferred in the Z-axis direction until reaching the submerged sheet attachment module 500.

12 and 13, when the seating panel 431 reaches the submerged sheet attachment module 500, the pickup device 510 descends to pick up the cell body 1 of the seating panel and then rise. do. In addition, the transfer device 520 receives the cell body 1 of the pickup device 510 by a finger 521. The transfer device 520 is reversely transferred along the X-axis direction. The transfer device 520 is stopped when facing the attachment robot 530.

The attachment robot 530 is rotated downward by approximately 45 ° in a state of being disposed below the transport device 520, as shown by a dotted line of FIG. 13, so as to face the bottom surface of the transport device 520. At this time, the transfer device 520 is lowered to transfer the cell body 1 to the attachment robot 530.

Then, the attachment robot 530 is rotated again 45 degrees, as shown in the solid line of Figure 13 to return to the original position. At this time, the cell body 1 of the attachment robot 530 maintains an inclined state of about 45 degrees.

In addition, the rotation member 540 of the submerged sheet attachment unit 502 is rotated so that the suction port 551 is directed downward. In addition, the suction port 551 of the shuttle member 550 picks up the submerged sheet 42 separated from the submerged sheet feeder 560.

The rotary member 540 of the submerged sheet attachment unit 502 is rotated such that the suction port 141 faces the surface of the cell body 1. The shuttle member 550 moves to the cell body 1 side. The suction port 551 of the shuttle member 550 attaches the submerged sheet 42 to the surface of the cell body 1.

Subsequently, the attachment robot 530 is rotated downward by approximately 45 ° again. At this time, the cell body 1 of the attachment robot 530 is disposed below the transfer device 520. The transfer device 520 descends to receive the cell body 1 from the attachment robot 530. At this time, the finger 521 of the transfer device 520 grasps both sides of the cell body (1).

The transfer device 520 is transferred along the X axis direction. Then, the transfer device 520 is lowered and transported to perform the next process, and if it is defective loads the cell body (1) to the discharge conveyor (610). The discharge conveyor 610 discharges the cell body (1).

According to the embodiment of the present invention as described above, the label sheet and the submerged sheet can be automatically attached by the battery pack manufacturing apparatus. In addition, the functional inspection can determine the good quality and defects, and prevent the worker from being exposed to harmful components when manufacturing the battery pack. In addition, the battery pack may be mass produced in a uniform quality.
