ABSTRACT:
An automatic plug pulling machine for integrated circuit (IC) tubes is disclosed. Conventionally on a semiconductor manufacturing line, IC tubes are used to transport IC packages such as DIPs, SOPs and SOJs from one processing station to another. Commonly, IC packages inside the tubes are removed by pulling out the plug manually. This can be very time consuming resulting in reduced throughput. With the automatic pulling machine disclosed in the present invention, the tubes are loaded on to a pair of robotic arms with slots and grooves to receive a tube. The arm transports the tube to a platform where the tube is clamped down and positioned relative to two plug pullers. The top plug puller with a finger-like notch, which when lowered to one end of the tube, snugly fits over the head of the plug, and the lower plug puller also fits the bottom profile of the head of the plug. Then the plug pullers are moved horizontally, that is, sideways to move the plug out from the tube automatically. The plug and the unplugged tube are discarded into a trough, and a bin, respectively.
