    • A lead frame unloading apparatus includes a pair of opposing plate members, one of which has a long horizontal slit. The opposing plate members define a central space where one or more sliding blocks are located, each of the sliding blocks having a vertical through hole at its center. A picker penetrates through the vertical hole within each respective sliding block, each picker is immobilized when it contacts a lead frame for pickup thereby allowing the sliding block to move vertically up and down on the immobilized pickers, each of the pickers having a vacuum suction device at one end thereof, and a vacuum screw at the other end thereof. The vacuum screw has a hollow projection connected to a vacuum supplier. A spring is disposed beneath respective of the one or more sliding blocks, with the spring being fitted to an outside of the vacuum suction device. Spring stoppers support the springs and fastening devices fasten the one or more sliding blocks to the opposing plate members. The one or more sliding blocks are horizontally movable within the central space between the two opposing plate members by loosening the fastening devices.
    • 引线框卸载装置包括一对相对的板构件,其中一个具有长的水平狭缝。 相对的板构件限定了一个或多个滑动块所在的中心空间,每个滑块在其中心具有垂直通孔。 拾取器穿过每个相应的滑动块内的垂直孔,当接触引导框架进行拾取时,每个拾取器被固定,从而允许滑块在固定的拾取器上上下垂直地移动,每个拾取器具有一个真空抽吸装置 一端,另一端为真空螺丝。 真空螺杆具有连接到真空供应器的中空突起。 弹簧设置在一个或多个滑动块的相应的下方,弹簧装配到真空抽吸装置的外部。 弹簧止动器支撑弹簧和紧固装置将一个或多个滑动块紧固到相对的板构件。 一个或多个滑动块通过松开紧固装置在两个相对的板构件之间的中心空间内可水平移动。
