A tray-positioning device comprises a driving unit and a positioning unit, wherein the positioning unit provides a plurality of sidewalls that correspond to a plurality of upper sidewalls of a tray. By allowing the driving unit to move the positioning unit toward the tray or vice versa that said individual upper sidewalls are in close contact with the corresponding sidewalls, the tray-positioning device is capable of providing precise positioning for the tray.

An air-suspended die sorter is disclosed, in particular an air-suspended die sorter capable of performing die sorting, die attaching and die pick-up in the semiconductor industry. The present invention provides an air-suspended die sorter capable of eliminating spring preload, and lowering mechanical friction so as to lift die sorting precision and elevate the success rate, and has a cylinder unit, a piston unit and a pressure unit. The piston type design and a precise control of pressure on top and on bottom of the piston, respectively, enables the present invention to offer an air-suspended state that has done away with stress problems associated with the use of springs. The present invention further provides a novel buffer design for reducing friction and die impact often encountered in prior art applications.

The invention is a device for fast taking out and putting in, especially the device can fast take out a chip from a wafer to put in another chip receptacle, wherein, the invention includes a gear set, which consists of a first big gear, a second big gear and a small gear; at least two driving device, which consists a first driving device and a second driving device; a link mechanism, which cooperates with the gear set to proceed that the link mechanism moves forth toward a non-horizontal direction and back toward the reverse direction, and moves down toward a non-vertical direction and up toward the reverse direction as well; a lift mechanism, which is driven by the first driving device, and a mold plate with gear set and link mechanism is then driven either to complete the actions of moving down toward a non-vertical direction and up toward the reverse direction as mentioned above. The second driving device drives gear set, which utilizes the rotation of gear set to complete the actions of moving forth toward a non-horizontal direction and back toward the reverse direction as mentioned above.

Device for fast taking out and putting in

A lead frame magazine handling device is disclosed which includes a magazine loading assembly, a magazine unloading assembly, two sets of receiving jaw mechanisms, a guided elevating assembly, and a programmable controller. The empty magazines are moved to the receiving jaw mechanism using the magazine loading assembly. At the same time, with the inner and outer sets of the receiving jaws in conjunction with the guided elevating assembly, one can alternately move the empty magazines and loads them to the lead frame receiving station to carry out the tasks of receiving and storing lead frames, and then, move to the magazine unloading assembly to unload the magazines which are fully loaded with lead frames so as to carry out the next operation.
