Object supplying apparatus

A method of causing a wound-on member to contact a printed wiring board and conveying the printed wiring board by utilizing a frictional force produced between the wound-on member and the printed wiring board, the method including the steps of providing two conveying units each of which includes a wound-on member and two rotatable wheels on which the wound-on member is wound to have a straightly extending portion which straightly extends between the two rotatable wheels, such that the two conveying units are spaced from each other in a direction parallel to a printed wiring board, and such that the respective straightly extending portions of the two wound-on members of the two conveying units cooperate with each other to sandwich the printed wiring board in a direction substantially parallel to the printed wiring board, and conveying the printed wiring board by rotating the rotatable wheels of the two conveying units, and thereby moving the two wound-on members, while utilizing a frictional force produced between each of the two wound-on members and the printed wiring board.

Printed-wiring-board conveying method and printed-wiring-board conveyor

A mounting head, a mounting apparatus, and a mounting method which are capable of contacting an electronic component with a substrate with a small contact load and mounting the component on the substrate, are provided. A suction device 120 is fit on a splined axis portion 118 of a support shaft 84 via a ball spline 126, is biased downward by a first spring 130, and is biased upward by a second spring 134. A suction nozzle 124 is attached to a nozzle holder 122 by engaging engagement ridges 172 of sheet springs 166 fixed to the suction nozzle 124 with engagement grooves 144 of the nozzle holder 122, respectively. Prior to the mounting of electronic components 178, a relationship between contact load and position of lift 28 is obtained, and a position to which the lift 28 is moved downward for mounting each electronic component 178 is pre-determined. Thus, each component 178 is contacted with a printed circuit board with an appropriate load. Each component 178 is contacted with the circuit board with a small load, by removing the self weight of the suction device 120 owing to the biasing action of the second spring 134 and reducing the frictional resistance produced between the suction device 120 and the axis member 84 owing to the provision of the ball spline 126.

Transfer type circuit board fabricating system

Method and apparatus for holding an electronic component prior to its placement on a circuit substrate. The component sucked by a sucker is first centered in one direction by closing movements of a first pair of opposed positioning members toward the component, and then centered in another direction normal to the above one direction by closing movements of a second pair of opposed positioning members which occur only after the first pair of positioning members are opened. The first pair of positioning members are provided on an assembly holding the sucker, and the second pair of positioning members are provided on the sucker holder assembly or separately from the sucker holder assembly. In the latter instance, the assembly holding the sucker and the first pair of positioning members are adapted to be movable relative to the separately provided second pair for alignment of the sucker with the separate second pair.
