Abstract:
In a chip reversing device used in a chip mounting apparatus for holding and vertically reversing a chip placed by a bonding nozzle, the chip is held on a chip holding unit disposed in a reversing member and is vertically reversed by turning the reversing member downward on an reversal shaft. After the reversed chip was received by a chip receiving unit, this chip receiving unit is lowered to a retracted position to return the reversing member to an original position. In this state, the chip receiving unit is raised to position the chip at a height level L for a chip transferring action. As a result, the reversing member does not protrude to above the height level for the chip transfer thereby to interfere with another mechanism, so that the chip mounting actions can be made efficient.
Abstract:
While a vicinity of a bottom surface-side region of a pressure-sensitive adhesive sheet (3) corresponding to an adhesion region (R1) of a semiconductor chip (1) are sucked and held, a plurality of protruding portions (30) of a removing member (21) are brought into contact with the bottom surface of the semiconductor chip through the adhesive sheet at the region. Also, the adhesive sheet is sucked in between the respective protruding portions so as to change a surface bonding of the semiconductor chip to the adhesive sheet by adhesion to a point bonding, and further the removing member is moved along the bottom surface of the semiconductor chip so as to change a position of the point bonding and decrease bonding force to the adhesive sheet by the adhesion. Then, the semiconductor chip is removed from the adhesive sheet.
Abstract:
The component suction device includes a suction nozzle (10) for sucking and holding a component (20), a nozzle turning device (25) for holding the suction nozzle and turning the suction nozzle, and a nozzle up-and-down device (26) which is located upward of the nozzle turning device and which is connected to the suction nozzle to serve for moving up and down the suction nozzle along an axial direction of the suction nozzle.
Abstract:
A component mounting apparatus (101) is provided with a board holding device (5, 6) for holding a board (8) at a board holding position (A, B, C and D), a first mounting head (4) for holding and taking out a component (2) fed from a first component feeding position (E) and mounting the component on the board held at the board holding position, a second mounting head (34) for holding and taking out the component fed from a second component feeding position (F) and mounting the component on the held board, and a component feeding device (11) having a wafer holding table (12) for holding a wafer (1) on which the respective components are fed so that the wafer holding table can be moved reciprocationally between the first component feeding position and the second component feeding position.

Abstract:
A device for feeding electronic parts, capable of surely feeding electronic parts in a stable posture to an electronic part mounting machine, stabilizing winding of a peeled-off top tape, and enhancing a mounting speed. When a reel (42) winds a top tape (4), a shutter (34) retreats and a slit (51) formed integral with the shutter (34) also retreats. Revolution of the reel (42) in a tape winding direction is effected by a restoring force of a restoring spring (39). When winding movement of the reel (42) is terminated and the shutter (34) retreats, electronic parts (1) are taken out at an electronic part taking-out position. A stationary roller (31) is provided between the slit (51) and the reel (42), and further a moving roller (32) is provided for keeping a length of the top tape (4) between the slit (51) and the stationary roller (31) substantially constant.
