Abstract: An overhead traveling camera inspection system for inspecting the condition of electronic semiconductor devices after being handled by a pick and place mechanism, and for automatically determining and calibrating the precise location of modules serviced by the pick and place mechanism for more accurate picking and placing of semiconductor devices.

Abstract: A high-speed tray transfer system for trays of semiconductor devices for increasing the rate at which trays are delivered to, and advanced through, a pick and place that moves orthogonal to the tray movement, so as to increase the overall throughput speed of a semiconductor handling machine. The invention utilizes two or more platens that carry trays. The platens can pass over, under or otherwise around each other so that while one platen is under and servicing the pick and place, another platen is cycling around and preparing another tray of electronic devices for the pick and place.

Abstract: A high-speed linear pick-and-place for increasing the speed of transfer of semiconductor electronic devices with accommodation for automated inspection or test. The invention includes two or more linear pick-and-place assemblies, each having two or more independently positionable pick-and-place nozzles. These assemblies are aligned such that the 4 or more nozzles can all pick and place to common shared locations. The 4 or more nozzles are operated so that they can pass by each other on their return stroke, except that nozzles sharing a rail cannot pass each other.

Abstract: A vibrator module adapted for use in a taper apparatus for advancing carrier tape having a plurality of compartments and for placing parts in the compartments. The vibrator module includes a motor that includes an output shaft that rotates in response to operation of the motor. The vibrator module also includes an eccentric weight mounted to and rotatable with the output shaft. The eccentric weight causes the motor to vibrate in response to rotation of the output shaft and eccentric weight. The vibrator module further includes a vibration transferring member interconnected with the motor and operable to transfer vibrations from the motor to the carrier tape to cause the parts to settle into the bottoms of the compartments.

Abstract: A method and apparatus for packaging parts in compartments of a carrier tape and affixing a cover tape over the carrier tape to trap the parts in the compartments. The method and apparatus provide for deflecting a flange of the carrier tape and sealing the cover tape to the deflected flange. The cover tape is tightened across the carrier tape when the carrier tape flange returns to its undeflected condition.

Abstract: Method and apparatus for sealing cover tape. A sealing mechanism is connected to an actuator that moves the mechanism toward an adhesively backed cover tape and a carrier tape. The sealing mechanism applies heat and/or pressure to the cover tape to activate and bond the cover tape to the carrier tape. A biasing member biases the mechanism away from the cover and carrier tapes. The actuator is actuable to overcome the biasing force of the biasing member and to initiate contact between the sealing mechanism and the cover tape. When the actuator is disengaged, the biasing member moves the sealing mechanism away from the cover tape.

Abstract: An apparatus including a pick-and-place apparatus and methods of operating a pick-and-place apparatus. The pick-and-place apparatus includes a frame, a plurality of vacuum rails movable in the frame, a row of vacuum nozzles on each vacuum rail, a plurality of stop members, a first mechanism for biasing the vacuum rails apart, toward, and into engagement with the stop members, and a second mechanism for biasing the vacuum rails together. The vacuum rails have a maximum pitch, in which the vacuum rails are biased apart by the first mechanism and engage the stop members, and a minimum pitch, in which the second mechanism overcomes the bias of the first mechanism and biases the vacuum rails together. The pick-and-place apparatus can pick up a two dimensional array of electrical parts, change spacing between the electrical parts, rotate the two-dimension array of electrical parts and place the parts in carrier tape.

Abstract: A drive for a carrier tape used in conjunction with a pick and place module of a machine for inspecting and handling advances the carrier tape to its desired position in two steps. Using the number of sprocket holes between compartments in the tape (n holes), the first step is n−1 sprocket holes. The second step takes the carrier tape the remaining distance to complete the advance to the distance equal to n sprocket holes. The tape is driven by friction rollers not by the use of the sprocket holes. The presence of a device in a compartment and its proper positioning in the compartment is also inspected.

Abstract: A method and apparatus for flattening cover tape prior to the cover tape being sealed to a carrier tape. The apparatus includes a cover tape flattener with a leading edge angled in the direction of the moving carrier tape and cover tape. The method and apparatus provide for smoothing the cover tape and sealing the cover tape to the carrier tape.

Abstract: The present invention provides a multiple output reel module (“MROM”) for use with a taper machine or any other machine outputting flexible media. The MROM includes an upper spindle shaft supporting a plurality of output reels, a lower spindle shaft supporting a plurality of output reels, a tape insertion assembly that positions the flexible media adjacent a hub of one of the output reels along a loading plane, a finger assembly that holds the flexible media against the hub, a cutting assembly for cutting the flexible media, and a reel moving mechanism operable to move the output reels into and out of alignment with the loading plane. The MROM also includes a reel support structure along which the upper and lower spindle shafts are moveable in a linear direction. The flexible media may be held against the hub of the output reels with a finger assembly or a length of adhesive tape.
