시임용접기{Seam welder}Seam welder

본 발명은 시임용접기에 관한 것으로, 특히 롤러와 일체로 형성된 샤프트를 완충기능을 갖는 액체형상의 통전매체로 감싸지지 함으로써 감싸여진 샤프트 부분이 본체 구멍에 직접접촉되지 않아 마모현상이 방지되어 용접전류를 일정하게 통전할 수 있도록 하는 것이다.The present invention relates to a seam welder, and in particular, the shaft formed integrally with the roller is wrapped with a liquid-type conducting medium having a buffer function so that the wrapped shaft portion is not in direct contact with the body hole, thereby preventing wear and preventing welding current. It is to allow constant electricity.

시임용접기는 회전롤러 형상을 갖는 전극을 사용하여 용접전류를 공급하면서 전극을 용접소재와 접촉되게 회전시켜 전기적인 저항열을 이용하여 박판을 용접하는 것으로, 접합부의 내밀성(內密性)을 필요로 하는 곳에 사용된다.The seam welding machine uses a electrode having a rotating roller shape to supply a welding current while rotating the electrode to be in contact with the welding material to weld the thin plate using electrical resistance heat. Used where

따라서 이러한 시임용접기는 여러 산업분야에서 적용되고 있는데, 그 사용예를 들면 휴대폰용 배터리(battery) 몸체를 박판의 플레이트로 감싸고정할 때 플레이트를 용접하거나 또는 휴대폰에서 노이즈를 제거하는 쇼필터(Saw filter), 즉 노이즈를 제거하는 칩에 플레이트를 감싸아 용접할 때 사용된다.Therefore, the seam welding machine has been applied in various industries. For example, a saw filter for welding a plate or removing noise from a mobile phone when the battery body for a mobile phone is wrapped in a thin plate is fixed. That is, it is used when welding the plate wrapped on the chip to remove noise.

도 1 은 종래에 가장 일반적으로 사용되는 시임용접기(1)를 타나내고 있다. 이 도면에서와 시임용접기(1)는 한 쌍의 회전롤러(2) 회전시켜 그 사이에서 이송되는 용접소재(3)를 전기적인 저항열로 용접하는 것이다. 더 자세하게 설명하면 본체(4)의 구멍(5)에 회전롤러(2)를 갖는 샤프트(6)가 회전가능하게 장착되어, 상기 샤프트(6)의 회전에 따라 회전롤러(2)가 박판의 용접소재(3) 일측면과 접촉된 상태로 회전하고, 이와 동시에 상기 용접소재(3)의 타측면과 접촉된 상태로 회전하는 타측 시임용접기(1)의 회전롤러(2) 사이에 용접전류가 통전될 때 용접소재(3)에 전기적인 저항열을 발생시켜 그 용접소재(3)를 용접하게 된다.Figure 1 shows a seam welder 1 most commonly used in the prior art. In this drawing, the seam welder 1 rotates a pair of rotary rollers 2 to weld the welding material 3 conveyed therebetween by electric resistance heat. In more detail, the shaft 6 having the rotary roller 2 is rotatably mounted in the hole 5 of the main body 4 so that the rotary roller 2 is welded to the thin plate according to the rotation of the shaft 6. The welding current is energized between the rotating rollers 2 of the other seam welding machine 1 which rotates in contact with one side of the material 3 and simultaneously rotates in contact with the other side of the welding material 3. When the electric resistance heat is generated in the welding material (3) to weld the welding material (3).

그런데 이와 같이 구성되는 종래 시임용접기(1)는 회전롤러(2)가 용접소재(3)를 가압한 상태에서 회전하게 되므로 상기 샤프트(6)는 회전롤러(2)측에 가까운 단부가 도 1 의 화살표 방향과 같이 용접소재(3) 반대방향, 즉 상방향으로 치우치게 되고 반대방향 단부는 하향으로 치우치게 된다. 따라서 이러한 상태로장시간 용접을 수행하게 되면 샤프트(6)와 구멍(5) 사이의 접촉부에는 마찰이 발생하여 그 부분이 점차 마모되어 샤프트(6)는 편심된 상태로 회전하게 된다.However, the conventional seam welder 1 configured as described above is rotated while the rotating roller 2 pressurizes the welding material 3, so that the shaft 6 has an end close to the rotating roller 2 side of FIG. As shown by the arrow direction, the welding material 3 is biased in the opposite direction, that is, upward, and the opposite end is biased downward. Therefore, when the welding is performed for a long time in such a state, friction occurs at the contact portion between the shaft 6 and the hole 5, and the part is gradually worn out, and the shaft 6 rotates in an eccentric state.

이와 같이 샤프트(6)와 구멍(5)의 접촉부가 마모되면 이들 사이에 접촉부분이 일정하지 않아 본체(4)의 터미널로부터 공급되는 용접전류가 용접소재(3)에 일정한 상태로 공급되지 않아 통전에 문제가 있었기 때문에 용접이 불안정하게 되었다.As such, when the contact portion between the shaft 6 and the hole 5 is worn out, the contact portion is not constant between them, so that the welding current supplied from the terminal of the main body 4 is not supplied to the welding material 3 in a constant state and is energized. Because of the problem, the welding became unstable.

또한, 상기 샤프트(6)가 편심된 상태로 회전하여 샤프트(6)의 회전이 원활하지 않게 되고, 편심된 접촉부에 마찰로 인한 열이 발생되어 샤프트(6)가 파손되거는 등 용접기 수명이 짧아지는 단점이 있었다.In addition, the shaft 6 is rotated in an eccentric state, the rotation of the shaft 6 is not smooth, heat generated by friction generated in the eccentric contact portion is shortened the welder life, such as damage to the shaft 6 There was a downside to losing.

이에 본 발명은 상술한 바와 같은 제반 문제점을 해결하기 위한 것으로, 그 목적은 롤러와 일체로 형성된 샤프트를 완충기능을 갖는 액체형상의 통전매체로 감싸지지하여 감싸여진 샤프트 부분이 본체 구멍에 직접접촉되지 않도록 하여 마모현상을 방지함으로써 용접전류를 일정하게 통전할 수 있도록 하는 시임용접기를 제공함에 있다.Accordingly, the present invention is to solve the above-mentioned problems, the object is that the shaft formed integrally with the roller is wrapped in a liquid conductive medium having a buffer function so that the wrapped shaft portion is not in direct contact with the body hole It is to provide a seam welder to prevent the wear phenomenon to ensure a constant current through the welding current.

이하, 첨부된 도면에 의거하여 본 발명 일 실시예 구성을 상세히 설명한다. 본 발명의 시임용접기(10)는 통상과 같이 본체(11)의 구멍(12)에 회전롤러(13)를 갖는 샤프트(14)가 회전가능하게 고정되는데, 상기 본체(11)의 외부 소정위치에는 전원공급을 위한 터미널(15)이 고정되고, 구멍(12) 내부 양측에는 상기 샤프트(14)를 지지하기 위한 베어링(16)이 설치된다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the seam welder 10 of the present invention, the shaft 14 having the rotary roller 13 is fixed to the hole 12 of the main body 11 so as to be rotatable, and at a predetermined position outside the main body 11. The terminal 15 for power supply is fixed, and bearings 16 for supporting the shaft 14 are installed at both sides of the hole 12.

이러한 시임용접기에 있어서, 본 발명의 시임용접기(10)는 도 2 내지 도 4 와 같이 본체(11)에 형성된 구멍(12) 길이방향 내주벽 둘레에 일정구간 수용실(17)이 형성되고, 이 수용실(17)에 전기전도율이 우수한 통전용 통전매체(18)가 수용되어 상기 샤프트(14)를 감싸지지하게 구성된다. 그리고 상기 본체(11)의 소정위치에는 상기 수용실(17)에 통전매체(18)를 공급할 수 있도록 상기 수용실(17)에 연통되게 공급유로(19)가 형성되고, 상기 공급유로(19)상에는 공급된 통전매체(18)가 역류되는 현상을 방지하는 역류방지수단(20)이 설치된다.In this seam welding machine, the seam welding machine 10 of the present invention has a predetermined section accommodation chamber 17 is formed around the inner circumferential wall of the hole 12 formed in the main body 11 as shown in Figs. The conduction medium 18 having excellent electrical conductivity is accommodated in the accommodation chamber 17 so as to surround the shaft 14. In addition, a supply passage 19 is formed at a predetermined position of the main body 11 so as to communicate with the accommodation chamber 17 so as to supply the conducting medium 18 to the accommodation chamber 17, and the supply passage 19 is provided. The reverse flow prevention means 20 is installed in the upper part to prevent the supplied conducting medium 18 from flowing backward.

상기 수용실(17)은 본체(11)에 형성된 구멍(12)의 내주벽에 둘레에 소정깊이 요입되는데, 내주벽에 전면적으로 요입될 수도 있고 부분적으로 요입될 수 있으나 통전매체(18)의 원활한 공급을 위해 전면적으로 요입되는 것이 바람직할 것이다. 또한 상기 수용실(17)의 길이는 상기 샤프트(14)를 충분히 지지할 수 있는 길이를 가져야 한다. 따라서 도면에서와 같이 양측 베어링(16) 사이에 전체적으로 요입되는 것이 좋다.The accommodating chamber 17 is recessed a predetermined depth in the circumference of the inner circumferential wall of the hole 12 formed in the main body 11, may be recessed entirely on the inner circumferential wall or partially recessed, but the smoothing of the conducting medium 18 may be performed. It would be desirable to infiltrate fully for supply. In addition, the length of the accommodation chamber 17 should have a length sufficient to support the shaft (14). Therefore, as shown in the figure, it is better to be entirely confined between the bearings 16 on both sides.

상기 통전매체(18)는 샤프트(14)를 감싸아 완충역할을 함과 동시에 본체(11)에서 공급되는 용접전류를 회전롤러(13)를 통해 용접소재에 전달해야 하므로 도전성이 우수한 재질로 구성되어야 하고, 또한 상기 수용실(17)에 원활한 공급을 위해 액체형상으로 구성되어야 한다. 이러한 조건을 만족하기 위한 일 실시예로써 금속이면서 상온에서 액체상태인 수은이 적합할 것이다. 상기 수은 이외에도 도전성을 가지며 액체 또는 겔상태의 물질이면 적용될 수 있을 것이다.The conducting medium 18 should be made of a material having excellent conductivity because it must surround the shaft 14 to act as a buffer and transfer the welding current supplied from the main body 11 to the welding material through the rotary roller 13. In addition, it must be configured in a liquid form for smooth supply to the accommodation chamber (17). Mercury, which is metallic and liquid at room temperature, may be suitable as an embodiment for satisfying such conditions. In addition to the mercury it may be applied if it is conductive and liquid or gel material.

상기 공급유로(19)는 통전매체(18)를 수용실(17)에 공급하기 위한 것으로, 본체(11) 적당위치에 수용실(17)과 연통되게 형성된다.The supply passage 19 is for supplying the conducting medium 18 to the storage chamber 17, and is formed in communication with the storage chamber 17 at an appropriate position of the main body 11.

상기 공급유로(19)상에 설치된 역류방지수단(20)은 수용실(17)에 공급된 통전매체(18)가 공급유로(19)를 통해 배출되지 않도록 하기 위한 것으로, 통상의 체크밸브를 사용할 수 있을 것이다.The reverse flow prevention means 20 installed on the supply passage 19 is for preventing the conducting medium 18 supplied to the accommodation chamber 17 from being discharged through the supply passage 19, and using a conventional check valve. Could be.

한편, 상기 샤프트(14)는 회전롤러(13)가 용접소재에 접촉되어 회전하면서 용접소재를 용접할 때 발생되는 전기적인 저항열에 의해 과열되지 않도록 상기 샤프트(14) 일측단부에서 축방향으로 소정깊이 냉각수를 저장하는 저장실(14a)이 더 형성된다. 그리고 상기 저장실(14a)에 입구에는 별도의 공급용 파이프(P)가 연결되어 상기 저장실(14a)에 냉각수를 연속적으로 공급하게 된다.On the other hand, the shaft 14 is a predetermined depth in the axial direction at one end of the shaft 14 so that the rotating roller 13 is in contact with the welding material and is not overheated by the electrical resistance heat generated when welding the welding material while rotating. A storage chamber 14a for storing the coolant is further formed. In addition, a separate supply pipe P is connected to an inlet of the storage chamber 14a to continuously supply cooling water to the storage chamber 14a.

다음은 첨부된 도면을 참조하여 본 발명의 사용상태를 설명한다.The following describes the use state of the present invention with reference to the accompanying drawings.

본체(11)의 구멍(12)에 샤프트(14)를 조립하게 되면, 상기 사프트(14)와 본체(11) 구멍(12) 사이에 수용실(17)에 형성된다. 이와 같이 샤프트(14)가 조립된 상태에서 상기 공급유로(19)를 통해 통전매체(18)를 상기 수용실(17)에 공급하게되면 액체의 통전매체(18)는 수용실(17) 내부로 흘러들어가 균일하게 채워지게 되며, 이후 상기 역류방지수단(20)을 이용하여 공급유로(19)를 차단하게 된다. 여기서, 상기 역류방지수단(20)이 체크밸브일 경우 통전매체(18) 공급후 자동적으로 차단된다.When the shaft 14 is assembled into the hole 12 of the main body 11, it is formed in the storage chamber 17 between the shaft 14 and the main body 11 hole 12. When the energization medium 18 is supplied to the accommodation chamber 17 through the supply passage 19 in the state in which the shaft 14 is assembled as described above, the fluid communication medium 18 of the liquid moves into the accommodation chamber 17. The flow is uniformly filled, and then to block the supply passage 19 by using the backflow prevention means (20). In this case, when the non-return means 20 is a check valve, the supply of the energizing medium 18 is automatically shut off.

도 2 는 샤프트(14)가 본체(11)에 조립된 상태인데, 수용실(17) 수용된 통전매체(18)는 상기 샤프트(14)를 감싸 지지하게 된다.2 illustrates a state in which the shaft 14 is assembled to the main body 11, and the energizing medium 18 accommodated in the accommodation chamber 17 surrounds and supports the shaft 14.

이와 같이 샤프트(14)를 감싸는 통전매체(18)는 도전성 소재이면서 액체이므로 샤프트(14)를 감싸아 완충작용을 하게 되므로, 상기 샤프트(14) 단부에 형성된 회전롤러(13)가 소재와 접촉된 상태로 회전하여 샤프트(14) 단부가 어느 일측으로 치우치더라도 샤프트(14)는 본체(11)의 구멍(12) 내주벽과 접촉되지 않아 마모현상이 발생되지 않는다. 이 때 샤프트(14)의 이동으로 압축되는 통전매체(18)는 압축률이 아주 작기 때문에 샤프트(14)를 안정되게 지지하면서 완충작용을 하게 된다.As such, the conductive medium 18 surrounding the shaft 14 is a conductive material and a liquid, so that the conductive medium 18 surrounds the shaft 14 to cushion the shaft 14. Thus, the rotating roller 13 formed at the end of the shaft 14 is in contact with the material. Even if the shaft 14 is rotated in the state, the shaft 14 does not come into contact with the inner circumferential wall of the hole 12 of the main body 11 so that wear does not occur. At this time, the energizing medium 18 compressed by the movement of the shaft 14 has a very small compression ratio, thereby buffering the shaft 14 while stably supporting it.

그리고 이와 같이 샤프트(14)를 지지하는 상기 통전매체(18)는 상기 샤프트(14)의 외주면에 전면적으로 접촉된 상태를 유지하게 되므로 공급되는 용접전류를 일정하게 통전시키게 된다.In this way, the energization medium 18 supporting the shaft 14 maintains the state of being in full contact with the outer circumferential surface of the shaft 14, thereby uniformly energizing the supplied welding current.

이와 같이 상기 통전매체(18)에 의해 지지되어 회전하는 샤프트(14)에 의해 회전롤러(13)가 회전하면서 박판의 용접소재를 용접하게 될 때 상기 샤프트(14)에 전기적인 저항열이 발생되더라도 저장실(14a)의 냉각수에 의해 샤프트(14)는 과열되지 않게 된다.In this way, even when electrical resistance heat is generated in the shaft 14 when the rotating roller 13 is welded by the shaft 14 that is supported by the energizing medium 18 and rotates, the welding material of the thin plate is welded. The cooling water in the storage chamber 14a prevents the shaft 14 from overheating.

이상과 같이 구성되는 본 발명은 수용실에 통전매체가 저장되어 있어, 회전롤러가 용접소재와 접촉되어 그와 일체로 형성된 샤프트가 어느 일측으로 이동하더라도 상기 통전매체가 완충역할을 하여 샤프트를 안정되게 지지하여 샤프트가 편심되더라도 구멍 외벽에 접촉되지 않게 하여 마모현상을 방지할 수 있게 된다. 그리고 상기 통전매체는 상기 샤프트가 편심될 때도 샤프트에 전체적으로 접촉되어 통전량을 일정하게 하는 장점을 가진다.According to the present invention configured as described above, the conductive medium is stored in the receiving chamber, so that the rotating medium is in contact with the welding material and the shaft formed integrally therewith moves to one side of the shaft to stabilize the shaft. Even if the shaft is eccentric to support, it is possible to prevent abrasion by not contacting the outer wall of the hole. In addition, the energizing medium has an advantage of constant contact with the entire shaft even when the shaft is eccentric.
