Abstract: The present invention discloses an exchanger for a tray feeder for transferring and exchanging a tray plate comprising: first and second support frames; a guide support unit including a support frame installed between the first and second support frames; a vacuum generator provided with a side of the first support frame; a nozzle support unit including a pitting unit for transferring a vacuum suction force by connecting it to the vacuum generator, a plurality of vacuum pad for performing a grasp of the tray plate with the vacuum suction force transferred from the pitting unit, and a plurality of stopper capable of supporting the tray plate; a head block connected to a side of the nozzle support unit; a guide block installed to a second belt as a state connected to the head block, thereby capable of guiding the nozzle support unit; a transfer means for transferring the guide block; a driving means for driving the transfer means.

Abstract: The present invention discloses a transfer for a tray feeder comprising: a base frame; a support frame installed at both sides of the base frame; first and second linear motion guiders installed oppositely and longitudinally to the inside of the support frame and having a plurality of first and second linear motion guide rails; first and second plates installed to an upper portion of the first and second linear guides and having a cylinder block capable of supporting a side of the tray received an electronic parts and the like; and a driving unit installed to a side portion of the support frame and for making the movement of the first and second plates; wherein the first and second plates can move along the first and second guide rails, crossing with each other.

Abstract: An elevation apparatus for a handler used for loading/unloading integrated circuit devices into/from a test tray is provide that includes an up/down block slidably mounted to be vertically displaceable with respect to a base plate. A nozzle block is affixed to the up/down block for displacement therewith. An aligner assembly is disposed above the nozzle block and supported by a pair of upper base blocks that are slidably mounted for displacement relative to the base plate. An elastically coupling assembly couples the pair of upper base blocks to the up/down block, the elastic coupling assembly upwardly displacing the pair of upper base blocks responsive to a corresponding upward displacement of the up/down block. The apparatus also includes a drive assembly secured to the base plate and coupled to the up/down block for vertically displacing the up/down block.
