Publication number: 20040197183Abstract: An exchanger for a tray feeder is provided which can easily and stably grasp and move a tray plate loaded with electronic parts using a suction force. A plurality of vacuum pads are provided on a moveable nozzle support unit of the exchanger. The vacuum pads are mounted on a plurality of suction nozzles along the surface of the nozzle support unit. A plurality of stoppers are interspersed between pairs of adjacent suction nozzles. These stoppers stably and precisely position the tray plate while it is grasped by the suction nozzles and moved through the action of the nozzle support unit.Type: ApplicationFiled: March 9, 2004Publication date: October 7, 2004Inventors: Jae Hyuk Cho, Sang Won Lee, Dong Suh Lee

Patent number: 6695546Abstract: 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.Type: GrantFiled: March 11, 2002Date of Patent: February 24, 2004Assignee: Mirae CorporationInventor: Dong Suh Lee
