  • Patent number: 4993588
    Abstract: An apparatus for separating objects of the same kind, in particular electronic components such as integrated circuits (IC's), that are delivered in succession in a sloping delivery passage, the apparatus having a stop member arranged in the region of the delivery passage that is displaced substantially transverse to the direction of delivery so that it holds back or holds fast the respective foremost object, and having a control circuit (P) that cyclically controls the displacing movement of the stop member, is to be designed so that while ensuring a relatively long service life it is suitable for use for different components, in particular with regard to their length.
    Type: Grant

  • Patent number: 4908126
    Abstract: An apparatus for testing and sorting electronic components (33), in particular IC's, is directly mounted on the mounting (2a, 2b to 10a, 10b), preferably forming part of a manipulator, for a test computer. In order to convey the components (33) between an input magazine (16), a testing head (20) and an output magazine (17) a suction head (20) is provided which is movable on a carriage guide (15) and which may be lowered. The mounting forming part of the manipulator permits the test computer (1) and the whole apparatus arranged on a slope so that the components (33) in the magazine rods (26) of the input magazine (16) and the output magazine (17) slide forwards under gravity.

  • Patent number: 4857838
    Abstract: An apparatus for testing electronic components, on which a testing device can be mounted, provided with a connecting plug for electrical connection of the electrical leads and couplings. Each coupling is provided with a fixed and movable coupling member for mechanical connection, with the couplings securing the testing device in the apparatus in a centered position by the inclined plane method. Stable coupling of the test device to the apparatus is desirable and is achieved by arranging at least three couplings in the form of a star on the appropriate attachment side.

  • Patent number: 4724965
    Abstract: An apparatus for testing and sorting electronic components comprises a testing device (4), an output magazine (3) having several parallel receiving ducts (34) for receiving tested components (8) and a component conveyor device (7) including a carriage (36) arranged between the testing device (4) and the output magazine (3) to move transversely to the receiving ducts (34) along a support rod (37) and an eccentric rod (38). The carriage is so engaged with the eccentric rod (38) that when the eccentric rod (38) is rotated at any position of the carriage (36) along the receiving ducts (34) the carriage swivels about the support rod (37) from a stop position to a release position to release a component (8) carried thereby to the adjacent receiving duct (34).
