본 발명은 리튬전지를 제조 생산하는 조립라인 특히 자동화 조립라인에서 리튬전지의 주요구성 요소인 캔과 소자에 고정되어 있는 팁단자간의 용접을 자동으로 실시 할 수 있도록 하는 용접장치에 관한 것이다.The present invention relates to a welding apparatus for automatically performing welding between a tip terminal fixed to a can and a device, which are main components of a lithium battery, in an assembly line for manufacturing and producing a lithium battery, in particular, an automated assembly line.
제1도는 리튬전지(1)의 구조를 보인 단면도이다. 리튬전지(1)는 캔(2)의 내부에 소자(3)를 내장하여 고정시키게 되며 소자(3)에 고정되어 있는 팁단자(3-1)(3-2) 중에서 하측에 있는 팁단자(3-2)를 캔(2)의 저면(2-1)에 용접시키게 되며 대체로 소자(3)와 팁단자(3-2)사이에 절연링(4)을 개입시킨 상태에서 중앙홀(3-3)의 바로 하측인 용접부(5)를 스포트 용접하게 된다.1 is a cross-sectional view showing the structure of the lithium battery 1. Lithium battery 1 is fixed inside the can (2) by the element 3 is fixed inside the tip terminal (3-1) (3-2) that is fixed to the element (3) 3-2) is welded to the bottom surface 2-1 of the can 2, and the center hole (3-) with the insulating ring 4 interposed between the element 3 and the tip terminal 3-2.

이하, 이와 같이 구성된 본 발명에 따른 용접장치(10)의 작동관계를 설명한다.Hereinafter, the operation relationship of the welding device 10 according to the present invention configured as described above.
벨트컨베이어(17)에 의해서 리튬전지(1)가 공급되고 또한 동시에 배출된다. 인덱스테이블(11)은 구동모터(13)에 의해 회전되며, 회전속도는 베이스테이블(12)의 저면에 부착된 인덱스기어박스(14)에 의해 감속된후 단속적으로 회전된다. 인덱스테이블(11)의 회전을 용이하게 할 수 있도록 하기 위하여 베이스 테이블(12)과의 사이에 트러스트베어링(15)이 구비되어 있다.The lithium battery 1 is supplied and discharged at the same time by the belt conveyor 17. The index table 11 is rotated by the drive motor 13, and the rotation speed is intermittently rotated after being decelerated by the index gear box 14 attached to the bottom surface of the base table 12. In order to facilitate the rotation of the index table 11, a thrust bearing 15 is provided between the base table 12 and the base table 12.
벨트컨베이어(17)에 의해 이송되어온 리튬전지(1)가 유입가이드(18)에 의해 안내되어 인덱스테이블(11)의 절연가이드(16)에 안치되면 감지센서(18-1)가 이를 감지하여 일·이차용접장치(30)(31)를 작동시키고, 이후 구동모터(13)의 작동에 의해 인덱스테이블(11)은 90도 회전된다.When the lithium battery 1 transferred by the belt conveyor 17 is guided by the inflow guide 18 and placed in the insulation guide 16 of the index table 11, the detection sensor 18-1 detects this. The secondary welding apparatuses 30 and 31 are operated, and then the index table 11 is rotated by 90 degrees by the operation of the drive motor 13.
유입가이드(18)를 따라 공급되는 리튬전지(1)는 그 하나가 회전되어온 절연가이드(16)에 인입되고, 일차용접장치(30)의 위치에는 리튬전지(1)가 이미 안치되어있는 절연가이드(16)가 회전 이동하게 된다.The lithium battery 1 supplied along the inflow guide 18 is introduced into the insulation guide 16, one of which is rotated, and an insulation guide in which the lithium battery 1 is already placed at the position of the primary welding device 30. 16 rotates.
절연가이드(16)에 안치되어 회전 되어온 리튬전지(1)는 지지봉(25)에 의해 일단의 외주연이 지지되고 실린더(20)가 작동되어 전진되는 압착봉(22)에 의해 타단이 지지되는데, 압착봉(22)이 스프링(23)에 의해 약간 탄발되어지므로 캔(2)의 외주연을 손상시키지 않는 상태로 지지하게 된다.The lithium battery 1, which is rotated by being placed in the insulation guide 16, is supported at one end by a supporting rod 25, and the other end thereof is supported by a crimping rod 22, in which a cylinder 20 is operated and advanced. Since the pressing rod 22 is slightly extended by the spring 23, the pressing rod 22 is supported without damaging the outer periphery of the can 2.
이 상태에서 일차용접장치(30)의 상·하측의 상용접팁작동용실린더(33)와 하용접팁작동용실린더(40)가 동시에 작동되면, 취부브래킷(34)이 LM레일(35)을 따라 하강하므로 상용접팁(29)은 소자(3)의 중앙홀(3-3)을 따라 하향하여 팁단자(3-2)의 상단에 접속되어지고, 하용접팁(41)은 캔(2)의 저면(2-1)에 연접되어진다.In this state, when the upper and lower commercial welding tip operating cylinder 33 and the lower welding tip operating cylinder 40 of the primary welding device 30 are operated at the same time, the mounting bracket 34 opens the LM rail 35. As it descends along, the commercial welding tip 29 is connected to the upper end of the tip terminal 3-2 downward along the central hole 3-3 of the element 3, and the lower welding tip 41 is can 2. Is connected to the bottom face 2-1 of the
상기 상용접팁(29)과 하용접팁(41)은 동일 수직선상에 위치하며 플러그(46)를 통하여 전원이 공급되면 용접장치(45)에 의해 대전류가 흘러 스포트 용접이 실시된다.The commercial welding tip 29 and the lower welding tip 41 are positioned on the same vertical line, and when power is supplied through the plug 46, a large current flows by the welding device 45 to perform spot welding.
상기 스포트 용접방법 및 장치는 통상의 스포트 용접과 동일하게 작동되므로 보다 구체적인 설명은 생략키로 한다.Since the spot welding method and apparatus operates in the same manner as in the conventional spot welding, a detailed description thereof will be omitted.
스포트 용접이 완료된 후 상·하 용접팁작동용실린더(33)(40)가 역으로 작동하여 상용접팁(39)과 하용접팁(41)을 원위치로 복귀시키며, 상·하용접팁(39)(41)이 복귀된 후 구동모터(13)가 작동되어 인덱스테이블(11)을 90도 회전시키면, 유입가이드(18)에서는 새로운 리튬전지(1)가 비어있는 절연가이드(16)에 공급되고 리튬전지(1)가 안치된 절연가이드(16)는 일차용접장치(30)의 위치로 이동되며 일차용접 된 리튬전지(1)는 이차용접장치(31)의 위치로 각각 이동된다.After spot welding is completed, the upper and lower welding tip operating cylinders 33 and 40 operate in reverse to return the commercial welding tip 39 and the lower welding tip 41 to their original positions, and the upper and lower welding tips 39 When the driving motor 13 is operated and the index table 11 is rotated 90 degrees after the return of the (41), the new lithium battery (1) is supplied to the empty insulation guide (16) in the inflow guide (18). The insulation guide 16 in which the lithium battery 1 is placed is moved to the position of the primary welding device 30, and the primary welded lithium battery 1 is moved to the position of the secondary welding device 31, respectively.
감지센서(18-1)가 유입된 리튬전지(1)를 감지함에 따라 일·이차용접장치(30)(31)는 상기 작동과정을 따라 작동되면서 일차용접장치(30)에서는 리튬전지(1)에 일차적으로 스포트 용접을 실시하게되고 이차용접장치(31)에서는 일차용접된 리튬전지(1)를 재차 용접시키게 된다.As the detection sensor 18-1 detects the introduced lithium battery 1, the primary and secondary welding devices 30 and 31 operate according to the above operation process, and the lithium battery 1 in the primary welding device 30. Spot welding is first performed on the secondary welding apparatus 31, and the primary welding lithium battery 1 is again welded.
용접이 완료된 후 구동모터(13)에 의해 인덱스테이블(11)이 90도 회전되면서 유입가이드(18)에서는 리튬전지(1)가 공급되고 배출가이드(19) 측으로는 용접이 완료된 리튬전지(1)가 배출되며, 회전이 완료된 후 일차용접장치(30) 및 이차용접장치(3)는 용접을 실시하게된다.After the welding is completed, the index table 11 is rotated 90 degrees by the driving motor 13, so that the lithium battery 1 is supplied from the inflow guide 18 and the welding is completed to the discharge guide 19. Is discharged, and after the rotation is completed, the primary welding device 30 and the secondary welding device 3 perform welding.
이와같이 인덱스테이블(11)이 90도 회전될때마다 용접이 완료된 리튬전지(1)는 배출가이드(19)를 따라 배출되어지고 용접이 되지 않은 리튬전지(1)는 유입가이드(17)를 통하여 공급되며 회전이 완료된후 일차 및 이차용접이 실시되어지는 것이다.As such, whenever the index table 11 is rotated by 90 degrees, the completed lithium battery 1 is discharged along the discharge guide 19, and the non-welded lithium battery 1 is supplied through the inflow guide 17. After the rotation is completed, the primary and secondary welding is performed.
본 발명은 상기와 같은 과정이 단속적으로 반복 실시되면서 리튬전지(1)를 용접시키게 된다.The present invention welds the lithium battery 1 while the above process is repeatedly performed intermittently.
이상에서와 같이 본 발명에 따르면 리튬전지의 인입과 배출이 자동으로 이루어지고 일차 및 이차용접이 항상 일정하게 실시되므로 품질을 향상시킬 수 있으며, 용접속도가 빨라져 생산성도 향상시킬 수 있다는 것이다.As described above, according to the present invention, the introduction and discharge of the lithium battery is automatically performed, and primary and secondary welding are always performed constantly, so that the quality can be improved, and the welding speed can be improved to improve productivity.
