본 고안은 몰딩완료된 리드프레임을 스트립(Strip)단위로 마킹하는 장비에서 자동으로 1개씩 공급하는 장치에 관한 것으로써, 좀더 구체적으로는 메가진내에 스트립을 적재시킨 상태에서 장비내에 장착하면 메가진내의 스트립이 순차적으로 마킹장비내로 공급될 수 있도록 한 것이다.The present invention relates to a device for automatically supplying a molded lead frame in a strip unit in a unit of strips, and more specifically, when the strip is loaded in a magazine and installed in the device, The strips can be fed into the marking equipment sequentially.

첨부도면 제1도는 종래장치를 나타낸 정면도로써, 설치판(1)에 메가진로더(2)를 회동시켜 주는 실린더(3)가 설치되어 있고 상기 설치판(1)의 하부에는 메가진로더(2)에 장착된 메가진(4)내의 스트립(5)을 순차적으로 1개씩 상승시키는 스탭모터(6)가 설치되어 있으며 상기 설치판(1)의 일측에는 메가진내의 최상부에 위치된 스트립(5)을 핑거(7)로 픽업한 다음 레일(8)의 상부에 올려 놓는 X,Y실린더(9)(10)가 설치되어 있다.1 is a front view showing a conventional apparatus, in which a cylinder 3 for rotating a mega loader 2 is installed on an installation plate 1, and a mega loader 2 is installed below the installation plate 1. Step motor (6) is provided to sequentially raise the strip (5) in the mega (4) mounted on the one side and the strip (5) located at the top of the mega on one side of the mounting plate (1) X and Y cylinders (9) and (10) are installed for picking up with the fingers (7) and then placing them on top of the rails (8).

따라서 실린더(2)의 구동으로 스트립(5)이 가득 차여진 메가진(4)을 메가진로더(2)에 장착한 다음 스탭모터(6)를 구동시키면 스탭모터(6)의 구동으로 메가진(4)내의 스트립(5)이 1스탭 상승된다.Therefore, if the mega (4) filled with the strip (5) by the driving of the cylinder (2) to the mega loader (2) and then drive the step motor (6) to drive the mega The strip 5 in (4) is raised by one step.

이와같이 메가진(4)내의 스트립(5)이 1스탭 상승하고 나면 X,Y실린더(9)(10)가 구동하게 되므로 핑거(7)가 스트립(5)의 상부로 이송되어와 최상부에 위치된 스트립을 파지하게 된다.As the strip 5 in the magazine 4 rises by one step, the X and Y cylinders 9 and 10 are driven so that the finger 7 is transferred to the top of the strip 5 and positioned at the top. Gripping the strip.

그후, X,Y실린더(9)(10)가 구동하여 핑거(7)를 레일(8)의 직상부로 이송된 다음 파지하고 있던 스트립(5)의 파지상태를 해제하면 스트립(5)은 자중에 의해 레일(8)의 상부에 얹혀지게 된다.After that, the X and Y cylinders 9 and 10 are driven to transfer the finger 7 to the upper portion of the rail 8, and then release the holding state of the holding strip 5 so that the strip 5 is self-weighting. It is placed on the upper portion of the rail (8).

이와같이 1개의 스트립(5)이 레일(8)에 얹혀짐을 별도의 센서가 감지하면 푸셔(도시는 생략함)가 동작하여 레일(8)에 얹혀져 있던 스트립(5)의 위치를 정확히 인덱싱한 후 아암 또는 벨트등의 이송수단에 의해 가공하고자 하는 다음 공정으로 이송시키게 된다.When a separate sensor detects that one strip 5 is placed on the rail 8 as described above, a pusher (not shown) operates to accurately index the position of the strip 5 placed on the rail 8, and then the arm Or it is transferred to the next process to be processed by a conveying means, such as a belt.

그러나 이러한 종래의 장치는 메가진의 최상부에 위치된 스트립을 X,Y실린더의 구동에 따라 핑거가 파지하여 레일의 상부에 얹어 놓도록 되어 있으므로 스트립의 이송중 동작불량으로 핑거에서 이송중인 스트립이 떨어져 쨈(jam)이 발생되는 경우가 종종 발생되었음은 물론 실린더 및 X,Y실린더의 순차동작으로 스트립을 상승시킨 다음 최상부에 위치된 스트립을 핑거가 파지하여 레일의 상부에 얹어 놓게 되므로 순차 동작에 의한 싸이클타임(Cycle time)이 길어져 생산성이 저하되는 문제점이 있었다.However, such a conventional device is to hold the strip located at the top of the mega to the top of the rail by gripping the finger in accordance with the X, Y cylinder drive, so the strip being transferred from the finger falls off due to a malfunction during the transfer of the strip. (jam) often occurred, as well as the sequential movement of the cylinder and the X, Y cylinders, and then the strip is raised, and the finger located on the top of the rail is held on the top of the rail by the fingers located on the upper strip. There was a problem in that productivity was reduced due to a long time (Cycle time).

본 고안은 종래의 이와같은 문제점을 해결하기 위해 안출한 것으로써, 레일의 직상부에 스트립이 담겨진 메가진을 장착시킨 상태에서 기어의 회전에 의해 최하방에 위치된 스트립을 순차적으로 레일의 상부로 공급할 수 있도록 하는데 그 목적이 있다.The present invention has been devised to solve such a problem in the prior art, and the strip located at the lowermost part by the rotation of the gear is sequentially moved to the upper part of the rail while the mega magazine containing the strip is mounted on the upper part of the rail. The purpose is to be able to supply.

상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 설치판의 상부로 노출되게 메가진이 장착되는 로더를 설치하고 상기 로더의 직하방에는 메가진내의 최하방에 위치되는 스트립이 얹혀지는 레일을 설치함과 동시에 레일의 사이에 스트립을 다음 공정으로 이송시키는 벨트를 설치하며 레일의 상부 양측에는 스탭모터의 구동으로 회전하면서 메가진에서 자유낙하하는 스트립을 1스탭씩 하강시키는 피딩로울러를 설치하여서 된 몰딩완료된 리드프레임의 자동공급장치가 제공된다.According to a form of the present invention for achieving the above object, to install a loader to be equipped with a magazine to be exposed to the upper portion of the mounting plate and to install a rail on which the strip is placed on the lowermost side in the magazine directly below At the same time, a belt is installed between the rails to transfer the strip to the next process.The molding is completed by installing a feeding roller that lowers the strip falling freely from the mega by one step while rotating by the step motor on both sides of the rail. An automatic supply of lead frames is provided.

이하, 본 고안을 일 실시예로 도시한 첨부된 도면 제2도를 참고로 하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, Figure 2 shows an embodiment of the present invention in more detail as follows.

첨부도면 제2도는 본 고안 장치를 나타낸 사시도이고 제3도는 본 고안의 동력전달 상태를 설명하기 위한 사시도로써, 본 고안은 설치판(11)의 상부로 노출되게 메가진(12)이 장착되는 로더(13)가 설치되어 있고 상기 로더의 직하방에는 스트립(14)이 얹혀지는 레일(15)이 설치되어 있으며 상기 레일(15)의 사이에는 스트립(14)을 다음 공정으로 이송시키는 벨트(16)가 설치되어 있으며 레일(15)의 양측에는 스탭모터(17)의 구동으로 회전하면서 메가진(12)에서 자유낙하하는 스트립(14)을 1스탭씩 하강시키는 피딩로울러(18)가 설치되어 있다.2 is a perspective view illustrating a device of the present invention and FIG. 3 is a perspective view for explaining a power transmission state of the present invention, and the present invention is a loader in which a mega 12 is mounted to be exposed to an upper portion of the installation plate 11. (13) is provided, and a rail (15) on which the strip (14) is placed is directly below the loader, and the belt (16) for transferring the strip (14) to the next process between the rails (15). And a feeding roller 18 is provided on both sides of the rail 15 to lower the strip 14 freely falling from the magazine 12 by one step while rotating by the driving of the step motor 17.

상기 스탭모터(17)의 구동으로 상호 반대방향으로 회전되는 피딩로울러(18)는 워엄(19)이 형성되어 있고 스탭모터(17)의 축(20)에는 나사산의 방향이 상호 반대인 워엄기어(21)가 형성되어 있어 스탭모터(17)의 구동에 따라 상기 피딩로울러(18)가 상호 반대방향으로 회전되면서 스트립(14)을 순차적으로 1개씩 하강시키게 된다.Feeding rollers 18 that are rotated in opposite directions by the driving of the step motor 17 are formed with worms 19 and worm gears having opposite directions of threads on the shaft 20 of the step motor 17 ( 21 is formed so that the feeding roller 18 is rotated in opposite directions as the step motor 17 is driven to lower the strips 14 one by one.

이와같이 구성된 본 고안의 작용, 효과를 설명하면 다음과 같다.Referring to the operation, effects of the present invention configured as described above are as follows.

먼저 로더(13)의 내부에 스트립(14)이 내장된 메가진(12)을 장착한 상태에서 스탭모터(17)의 구동에 따라 피딩로울러(18)를 1스탭씩 회전시키면 상기 피딩로울러(18)에 형성된 기어의 내부에 스트립(14)이 1개씩 삽입되어 하강되므로 스트립이 순차적으로 레일(15)에 얹혀지게 된다.First, when the feeding roller 18 is rotated by one step in response to the operation of the step motor 17 while the mega 12 having the strip 14 embedded therein is mounted in the loader 13, the feeding roller 18 Since the strips 14 are inserted and lowered one by one in the gear formed in the), the strips are sequentially placed on the rails 15.

이에따라 메가진(12)의 최하방에서 분리되는 스트립(14)은 레일(15)사이에 위치된 벨트(16)에 얹혀지게 되므로 다음 공정으로 이송되어 후공정을 거치게 된다.Accordingly, the strip 14 separated from the bottom of the mega 12 is placed on the belt 16 located between the rails 15, and thus, the strip 14 is transferred to the next process to undergo a later process.

이와같이 메가진(12)내의 스트립(14)이 1피치 하강되어 벨트(16)의 회전으로 다음 공정을 이송되면 메가진(12)내의 또 다른 스트립(14)이 하강되어 전술한 바와 같이 레일(15)사이의 벨트(16)에 얹혀지게 되므로 순차적인 공정이 수행되는 것이다.As such, when the strip 14 in the magazine 12 is lowered by one pitch and transferred to the next process by the rotation of the belt 16, another strip 14 in the magazine 12 is lowered and the rail 15 as described above. Since the belt 16 is placed between the sequential process is performed.

상기한 바와 같은 공정시 피딩로울러(18)의 구동은 별도의 제어수단(도시는 생략함)에 의해 스탭모터의 구동을 제어함으로써 가능해지게 되는 것이다.In the process as described above, the driving of the feeding roller 18 is made possible by controlling the driving of the step motor by a separate control means (not shown).

이상에서와 같이 본 고안 장치는 메가진내의 스트립을 피딩로울러의 회전에 따라 1스탭씩 하강시키면서 다음 공정으로 순차 이송시키게 되므로 픽업수단의 설치에 따른 공간점유율을 최소화하게 됨은 물론 스트립의 이송시에 스트립의 파지불량에 따른 쨈의 발생을 미연에 방지하게 되므로 싸이클 타임을 줄이게 되는 효과를 얻게 된다.As described above, the device of the present invention sequentially transfers the strip in the magazine to the next step while descending by one step according to the rotation of the feeding roller, thereby minimizing the space occupancy according to the installation of the pickup means, and of course, the strip during transportation of the strip. This prevents the occurrence of 쨈 due to poor gripping, thus reducing the cycle time.
