Pick and place apparatus for electronic device inspection equipment

摘要

A technology related to a pick-and-place apparatus for electronic device inspection equipment is provided. The pick-and-place apparatus includes the guiding unit that can interact with a loading element and can guide the picker to load the electronic devices at a correct position on the loading element. Therefore, the pick-and-place apparatus can allow the electronic devices, for example, semiconductor devices having a ball type of electrical contact lead (BGA, FBGA, etc.), to electrically contact the tester in a stable manner when the tester inspects the electronic devices.

主权项

1. A pick-and-place apparatus for electronic device inspection equipment, the apparatus comprising:
a carrier board having a plurality of inserts in which electronic parts are seated and held; an opener located at a lower side of the carrier board to release a holding state of holding units which can hold the electronic parts of the inserts while rising; a guide rail which serves to prevent the carrier board having the inserts from being separated beyond a predetermined interval in an upper direction while the opener rises; a plurality of picking apparatuses that pick up electronic devices loaded on a first loading element, that move the electronic devices, and that unload the electronic devices onto a second loading element; and a module-forming block that joins the plurality of picking apparatuses in one module, wherein each of the picking apparatuses 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; anda 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 guiding member joined to the body and having position setting pins for setting positions between the picker and the second loading element by being inserted into position setting holes formed in the second loading element, wherein the guiding member comprises a stopper disposed at a lower portion of the guiding unit, and spaced apart from the body to prevent the body from being lowered further after the body has been lowered to a certain distance while the body is being lowered by an operation of the module-forming block in a state where a lower surface of the stopper gets in contact with an upper surface of an insert of the plurality of inserts, and wherein the guiding unit further comprises a first elastic member for pressurizing the electronic parts of the inserts which are in a released state in a downward direction by being contracted until the body cannot lower further because an upper surface of the stopper comes into contact with a lower surface of the body within a preset range of movement distance with respect to the body, when the body lowers in a state where the lower surface of the stopper gets in contact with the upper surface of the insert while the picking units of the picking apparatuses downwardly operate the electronic parts of the inserts which are in the released state to downwardly pressurize the electronic parts of the inserts which are in the released state, after the opener rises to release the holding state of the holding units of the inserts of the carrier board and the carrier board rises to a predetermined distance and after the module-forming block lowers such that the position setting pins of the picking apparatuses are inserted into the position setting holes so as to set a position between the picker and the second loading element.
