专利汇可以提供Wafer basket transfer apparatus专利检索,专利查询,专利分析的服务。并且A wafer basket transfer apparatus particularly useful for transferring baskets of wafers in the semi-conductor processing industry from one processing bath to an adjacent bath. The apparatus includes a stationary frame plate to which is slideably mounted for vertical movement a slide plate. A lifting arm with a basket lifting hook at one end is rotatably driven at its other end by a motor. A cam and cam follower are respectively mounted on the slide and the frame plates, the cam rotating with the arm and having a cam edge non-symmetrical with respect to the axis of rotation of the arm. As the arm rotates with respect to the motor, the cam edge engages the cam follower to raise and lower the slide plate with respect to the frame plate, the freeswinging basket lifting hook describing a curved, vertically elongated closed path. The apparatus of the invention lifts a basket containing semi-conductor wafers substantially vertically upwardly from one processing bath to a substantial height, and then deposits the basket substantially vertically downward into an adjacent bath.,下面是Wafer basket transfer apparatus专利的具体信息内容。
