  • Patent number: 11400605
    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 locking mechanism for a press head, and an electronic device testing apparatus comprising the same, wherein a slider and a locking pin are disposed on the press head and a test socket substrate, respectively. When the press head is moved and engaged with the test socket substrate, an actuator drives the slider to secure the locking pin, so as to secure the press head and the test socket substrate and prevent the press head and the test socket substrate from being separated from each other. The mechanism is simple in construction, easy to install and maintain, reliable, and can be integrated into the support arms, and occupies a relatively small space. Energy is consumed only when the actuator is actuated to effect locking or unlocking. That is, only when the slider is driven and moved, energy is consumed.
