  • Patent number: 11622485
    Abstract: A pick arm for a pick and place apparatus for electronic devices has a main body having a proximal end whereat the pick arm is mountable onto a pick arm support, and a distal end at which a collet is mounted for holding an electronic device. A first rigid body is located adjacent to the proximal end of the pick arm and a second rigid body is located adjacent to the distal end of the pick arm. The first and second flexures connect the first rigid body to the second rigid body. Moreover, the first flexure is spaced from the second flexure, and the first and second flexures have opposing faces that are arranged substantially parallel to each other. An actuator is operative to apply a biasing force onto the second rigid body so as to bend the first and second flexures relative to the first rigid body for biasing the collet of the pick arm to move.

  • Patent number: 10093491
    Abstract: A pick-and-place apparatus has a rotary turret and a plurality of pick arms arranged on the rotary turret for picking up and placing electronic devices during pick and place operations. A transmission stator and a transmission rotor are mounted on the rotary turret with an air gap between the transmission stator and the transmission rotor such that the transmission rotor is rotatable relative to the transmission stator. At least one motor for actuating at least one pick arm during the pick and place operations is operatively coupled to the transmission rotor. The transmission stator and the transmission rotor are configured to transmit data signals wirelessly across the air gap for driving the at least one motor to actuate the at least one pick arm.

  • Patent number: 8910775
    Abstract: A transfer apparatus has a conveying track for electronic devices in a row, two vacuum passages to create vacuum forces to hold electronic devices against the conveying track at first and second positions respectively preventing overlapping of electronic devices; and sensors arranged with respect to the conveying track, the first sensor detects presence or absence of the leading electronic device at the first position for removal of the leading electronic device from the conveying track, and the second sensor detects presence or absence of the leading electronic device at a sensor position between the first and second positions as the leading electronic device is conveyed along the conveying track from the second to the first vacuum passage.
