Patent ID: 8496426

Claim:
A pick-and-place apparatus for electronic device inspection equipment, the apparatus comprising: a plurality of picking apparatuses that pick up electronic devices loaded on a first loading element, move the electronic devices, and unloads the electronic devices onto a second loading element; and a module-forming block that joins the plurality of picking apparatuses in one module, wherein at least one picking apparatus comprises: a body fixed to the module-forming block; a picker having a picking unit, coupled to the body, for picking up an electronic device or releasing the picked electronic device; and a guiding unit for interacting with the second loading element and for guiding the picker to load the electronic devices at a correct position on the second loading element, wherein the guiding unit comprises a stopper at a lower portion of the guiding unit, the stopper formed around the picking unit, wherein the guiding unit comprises a guiding member having position setting pins, joined to the body, for setting positions between the picker and the second loading element by being inserted into position setting holes formed in the second loading element until a lower surface of the stopper contacts an upper surface of the second loading element and wherein the second loading element comprises a plurality of holding apparatuses to adjustably hold the electronic devices, wherein the guiding member is joined to the body so that it can be relatively moved within a preset range of movement distance with respect to the body in the direction of the second loading element or opposite thereto, and the guiding unit further comprises a first elastic member exerting an elastic force on the guiding member toward the second loading element, and wherein at least one picking apparatus further comprises a second elastic member for maintaining an elastic force with respect to the module-forming block, the second elastic member being joined so that it can be relatively moved within a preset range of movement distance with respect to the module-forming block in the direction toward the second loading element or opposite thereto, and the second elastic member has a greater elastic coefficient than the first elastic member does.
