Abstract
본 발명은 가이드 레일이 리드 프레임 스트립의 사이드 레일이 놓여지는 하부 가이드 레일과, 상기 하부 가이드 레일과 소정의 간격을 이루며 상부에 형성된 상부 가이드 레일과, 상기 상부 가이드 레일과 상기 하부 가이드 레일의 사이에 상하로 유동이 가능하도록 형성된 가이드 피더와, 상기 가이드 피더의 상부에 있는 상기 상부 가이드 레일에 형성된 가압 수단을 포함하며, 상기 가이드 레일이 리드 프레임 스트립이 공급될 방향으로 유동이 가능하도록 유동 수단을 구비하는 리드 프레임 스트립을 공급하기 위한 가이드 레일을 갖는 절단/굴곡 장치를 제공함으로써, 리드 프레임 스트립의 피치 및 프레임당 제품 수에 관계없이 작동이 가능하며 피딩 암에 의한 리드 프레임 스트립의 손상 및 문제가 감소될 수 있으며 절단/굴곡 장치의 크기를 축소하는 효과를 나타낸다.According to the present invention, a guide rail includes a lower guide rail on which a side rail of a lead frame strip is placed, an upper guide rail formed at a predetermined distance from the lower guide rail, and between the upper guide rail and the lower guide rail. A guide feeder formed to be able to flow up and down, and pressing means formed on the upper guide rail above the guide feeder, the guide rail being provided to flow in a direction in which the lead frame strip is to be supplied. By providing a cutting / bending device having guide rails for supplying lead frame strips, the operation is possible regardless of the pitch of the lead frame strips and the number of products per frame, reducing damage and problems of the lead frame strips by the feeding arm. Can be reduced size of cutting / bending device It shows the effect.
