Abstract

An automatic removal system for automatically removing a tape and a resin exposed to the outside of a battery module includes a removal assembly including a removal device for removing the tape and the resin, and an automatic multi-axis robot coupled to the removal assembly and configured to drive to remove the tape and the resin of the battery module.

First claim

1 . An automatic removal system for automatically removing a tape and a resin exposed to an outside of a battery module, the system comprising:
a removal assembly including a removal device for removing the tape and the resin; and an automatic multi-axis robot coupled to the removal assembly and configured to drive the removal assembly to remove the tape and the resin of the battery module.

2 . The system of claim 1 , wherein the removal device includes a first removal device for removing the tape and the resin attached to the tape.

3 . The system of claim 2 , wherein the removal device further includes a second removal device for removing the resin remaining on the battery module left by the first removal device.

4 . The system of claim 2 , further comprising a transfer module, wherein the transfer module grips the battery module and moves the battery module to a transfer shuttle.

5 . The system of claim 4 , wherein the transfer shuttle includes a pair of transfer rails that are adjacent to each other, and
wherein the battery module is loaded on the pair of transfer rails and moves to an aligner positioned in a front side of the transfer rail.

6 . The system of claim 5 , wherein the aligner includes a stopper, and a pair of pressers respectively installed on outer sides of the pair of transfer rails,
wherein each of the pressers includes a pressing rod that enters an inside of a respective transfer rail or retracts from the respective transfer rail, wherein the pressing rod presses a side surface or a rear surface of the battery module when the pressing rod enters the inside of the respective transfer rail, and wherein the stopper blocks a forward movement of the battery module, so that the battery module is fixed in place.

7 . The system of claim 2 , further comprising spray nozzles arranged to spray high-pressure air,
wherein compressed air discharged from the spray nozzles causes a portion of the tape to be separated from a casing of the battery module and directed in a predetermined direction, so that the first removal device of the removal assembly grips the tape.

8 . The system of claim 3 , further comprising a cleaner configured to contact the second removal device and remove the remaining resin adhered to the second removal device.

9 . The system of claim 2 , further comprising a collector configured to collect the tape attached to the first removal device.

10 . The system of claim 2 , wherein the first removal device includes rods arranged side by side along one side of a base of the removal assembly and each of the rods extending downward, and a gripper integrally formed at a front end of each of the rods.

11 . The system of claim 2 , wherein the first removal device includes blocks arranged along one side of a base of the removal assembly to face a lower surface, and a scraper mounted on a lower surface of the blocks and configured to remove the tape and the resin.

12 . The system of claim 3 , wherein the second removal device includes a support bracket or block formed on a second side of the removal device opposite to a first side in which the first removal device is arranged, and a knife or scraper installed on the support bracket or block to remove the resin.

13 . The system of claim 1 , wherein the automatic multi-axis robot has a multi-joint structure including a body, a first robot arm connected to the body, and a second robot arm connected to the first robot arm,
wherein a pivotable drive arm and a coupling portion for being coupled to a base of the removal assembly are sequentially formed at a front end of the second robot arm.

14 . A method of automatically removing the tape and the resin exposed to the outside of the battery module using the automatic removal system of claim 2 , the method comprising removing the tape and the resin attached to the tape by moving the first removal device along a first direction of the tape attached to the battery module.

15 . The method of claim 14 , further comprising removing the remaining resin by moving the second removal device in a second direction perpendicular to the first direction.
