IC punching formation equipment

Abstract

The IC punching formation equipment includes one feeder, one separator and one discharger. On the frame, there are cam shaft with fixed separation detecting cam, separating cam, vertical discharge cam and horizontal discharge cam; and oscillating arm shaft fixed to the cam shaft and with connected separation detecting oscillating arm, separating oscillating arm, vertical discharge oscillating arm and horizontal discharge oscillating arm. All the cams and all the oscillating arms cooperate to complete the separation detection, separation, discharge elevation and horizontal discharge moving of the lead frame separately. The present invention uses only one power source, and has high punching speed, high capacity and stable running.

Description

technical field [0001] The invention relates to a punching and forming equipment for separating integrated circuit lead frames. Background technique [0002] In the production of integrated circuits, as shown in Figure 1, the lead frame 80 is separated into products 81 and waste materials 82 on the punching and forming equipment. The action process generally includes separation detection, separation and discharge, and the discharge action includes the lifting and lowering of the adsorption device. Move back and forth for two actions. Separation generally uses a cylinder as a power to guide the separation mold to separate the product. Before separation, it is necessary to detect whether the lead frame is in place in the separation mold. Therefore, the separation mold needs to have two actions of separation detection and separation of the position of the lead frame. Independent cylinders are used as power to complete the action. The existing integrated circuit punching and f...

Problems solved by technology

[0005] The advantage of this kind of integrated circuit punching and forming equipment is that the structure is simple, but its disadvantage is that the four actions of separation detection, separation, adsorption device lifting and forward and backward movement are related in time sequence, and four different power sources are used. To drive, because the reaction time of the cylinder action is long, for the sake of safety, each action has a certain safety time. When the speed increases, the safety time of each independent action is reduced, and the reliability of the entire equipment is reduced. Therefore, the overall system It is difficult to increase the speed. At the same time, the action is completed under the cooperation of multiple power sources, which brings great difficulties to adjustment and control. Its stability and reliability are low, which seriously affects the improvement of production capacity.
