  • Patent number: 7591495
    Abstract: A pick-and-place head device with a pushing mechanism for handling electronic components is disclosed in this invention. The pick-and-place head device includes a fixing base connected to a robot arm and a cylinder member disposed on the fixing base, the cylinder member has a first pressure passage, one end of the first pressure passage is connected to a suction member and another end of the first pressure passage is connected to a first pressure source, and the cylinder member is connected to a second pressure source so as to push at least one pushing tip. One of the first pressure source and the second pressure source is controllably selected by a pressure controller at a given time to have a pressure operation so as to enable the suction member to pick up an electronic component or to enable the pushing tip to push the electronic component.

  • Patent number: 7454885
    Abstract: A tray to tube manual exchanger is disclosed herein. The manual exchanger includes a tray-fastening module and a bi-axle-rotating module. The tray-fastening module includes a tray-fastening member, a buffer-rail substrate, and a tube-inserting member. The buffer-rail substrate having a plurality of rails is disposed under the tray-fastening member, and the tube-inserting member is disposed at the outlets of the plurality of rails for respectively receiving tubes. The bi-axle-rotating module is pivotally connected to the tray-fastening module. The tray-fastening module clips a tray carrying a plurality of packaged semiconductor devices at a horizontal position, followed by rotating 180 degrees around a second rotating axle of the bi-axle-rotating module, thereby falling the packaged semiconductor devices of each row of the tray onto each rail.
