Abstract: A rotatable cushioning pick-and-place device primarily comprises a motor, a body, a cushioning module and a pick-and-place module. The cushioning module is disposed in a first chamber of the body and comprises a rotary bearing which is connected to a drive shaft of the motor, and coupled to a driven shaft sleeve through a rotary follower. The rotary follower is driven by the rotary bearing to drive the driven shaft sleeve to rotate, thereby allowing the rotary bearing to displace relative to the driven shaft sleeve axially. The cushioning spring is arranged between the rotary bearing and the driven shaft sleeve. A first sealing ring and a second sealing ring of the pick-and-place module are fixed on the body to cooperatively and air-tightly seal the second chamber.

Abstract: The present invention relates to a quick release assembly for a pressing head and an electronic device testing apparatus having the same. The quick release assembly comprises an upper base, an actuator and a lower base. When the lower base is to be mounted on the upper base, the actuator drives a movable head to a first position; the movable head passes through an open slot of the lower base; then, the actuator drives the movable head to a second position so that the lower base is retained by the movable head. The open slot of the lower base is firstly fitted on the movable head of the actuator located on the upper base. At this time, the actuator is controlled to drive the movable head to the second position from the first position.
