Description

[Detailed Description of the Invention] The industrial application field is the random access method for printed circuit boards.
i, I: (p'j'rlIn a device that mounts one item, it is related to a sub-component supplying device Y that aims to shorten the time for supplying electronic components).

The configuration of the conventional example and its problems The conventional lanotum access method electronic component supply Isoba, the first
As shown in the conceptual diagram in the figure, a printed circuit board 2 is held on a base Y table 1, and a head 3 takes out five electronic components from a component supply section 4 and mounts them on the printed circuit board 2. In the parts supply 77 and iS4, a series of 'Y[+parts, s', σ' are installed, and the parts are fed out one pitch at a time. A provided feed 7 feeds the parts by driving to the ejecting position 8.The parts supply part 4 moves in the input direction and takes out different known electronic parts. 1, 'Ichikosho 1昂7,5゜5', , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

T2 and T3 swing from the cassette 6 to the printed circuit board 2''. From T3 to T4, electronic ↑ goes to printed circuit board 2 for 1s
Implement item 6.

b is the feed timing 8, and the next six electronic components are sent to the take-out position 8 between T2 and T6.

C is rXl! This is the timing when the product supply section can be moved, and it is not possible to move during vacuum suction from 11 to T2 and during feeding from T2 to T5. When the mounting machine's one cycle time T1 to T4 is covered by W, if the component supply section 4 is moved, the movable time will be shortened, and the equipment will become more complex. Furthermore, it requires individual feed timing, which is not practical.

The purpose of the invention is that, in view of the above-mentioned drawbacks, the next electronic component to be mounted is of a different type, and is attached to an adjacent cassette.
) At the timing of vacuum suction, the parts are immediately supplied to the A stand without feeding the adjacent cassettes, and after the vacuum suction is performed, the components are immediately supplied (81S) (it performs hyperactivity and is set longer than the component supply section transfer time). The present invention provides an electronic component supply device that can shorten the mounting cycle of a random access type mounting machine and reduce the influence of component supply section movement time.

Structure of the Invention The electronic component feeding device of the present invention has a ratchet image (11) in the vicinity of the jig cassette, which is provided at equal pitches in the horizontal direction to feed the taped electronic components one pitch at a time.
A plurality of feed portions are provided vertically movable up and down and are provided at equal pitches facing the cassette, and this feed portion is supported by a swinging force of 5T to drive the ratchet mechanism for one pitch feed. A feed lever provided horizontally in the feed portion, a sliding port held in the link Lf, a piston held by the link, and a pneumatic cylinder for driving this piston;
In a random access type mounting machine, the transfer time of the product supply section can be set longer using the feed lever or link mechanism of the screw 1 and the link mechanism. One cycle time of the mounting machine is shortened! l'I is something that can be measured.

DESCRIPTION OF EMBODIMENTS Below, one embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 3 is a schematic diagram of the electronic F and CB product mounting apparatus in the first embodiment of the invention. 1 is an XY table,
2 is a printed circuit board, 4 is a parts supply part, and electronic parts 5 are stocked on tape 9, which has equally pitched sprocket holes and a parts storage part, and 1 pack and cassette 6 or 41iii are stocked therein. . 3 is a head, and a lever 11 is swung around a shaft 10 by a cam (not shown).
There is a hollow shaft 12 that is supported by a cam (W not shown) and swings up and down via a lever, and is connected to a vacuum generator (not shown) through a tube 13.
Vacuum the 5 electronic components using the nostle 1XIj at the lower end of the unit. Reference numeral 14 denotes a chuck, which regulates the posture of the electronic component 5 that has been vacuum-suctioned.

Perform two consecutive downward movements from T2 to T5. d is a case in which six electronic components of the same type are mounted in succession, and the feed lever 18 in FIG. F, r j drive and feed] Perform assistant work. 1'2 to T5 of d is the time during which compression air flows into the cylinder 21 and pushes 22 pistons. The feed levers 1g' and 1d' are at position B, and the filling operation does not occur.

e is the output 1 where the electronic component 5 is vacuum-adsorbed by the Nakasuke 12 when the different ``electronic component 5'' or d'' is mounted next.
Move the feed lever 18' or 1g' to 1°1 to 1'21i1, then move the feed lever 18' or 1g', and then move the part supply 4 of f. . In this case, compared to C in FIG. 2, the feed time T2 to T15 is longer than the moving time.

Effects of the Invention In this way, the present invention provides a random access type mounting machine with a plurality of feed sections provided facing the cassettes, and a feed operation schedule for adjacent cassettes at the timing of vacuum suction. By doing so, the component supply section can be moved immediately after vacuum suction, which lengthens the moving time and shortens the one-cycle time of the mounting machine.
