Wireless signal transmission in a pick-and-place apparatus

A pick-and-place apparatus comprising:

• 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 mounted on the rotary turret, and an air gap between the transmission stator and the transmission rotor such that the transmission rotor is rotatable relative to the transmission stator;
• and
• at least one motor for actuating at least one pick arm during the pick and place operations, the at least one motor and the at least one pick arm being operatively coupled to the transmission rotor;
• wherein 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.
