Description

[Detailed description of the invention] This invention is an electronic component series cutting method that selects and separates a desired electronic component series from a plurality of electronic component series in an automatic insertion device etc. that inserts electronic components into a printed circuit board. This invention relates to an electronic component transfer device that holds pieces on a pallet and transfers them to a chuck or the like that holds the electronic components.

The present applicant has previously proposed an electronic component transfer device that transports a pallet holding continuous cut pieces of electronic components by running it in a horizontal plane using an endless belt mechanism such as a chain. In this case, the supply unit cuts the series of electronic components with a cutter to create continuous pieces of electronic parts so as to have one electronic component, and supplies the continuous pieces of electronic parts to the pallet. It is arranged so as to face the straight running part of the road.

By the way, in the conventional apparatus, the cutter of the supply section is configured to always operate at a constant timing regardless of whether or not it is necessary to create continuous cut pieces of electronic components. However, when the number of electronic component series increases and the number of supply units increases correspondingly, the number of supply units selected in one supply operation is one on average, and the selected supply unit Only the continuous cut pieces of electronic components are supplied to the opposing pallet, and the cutters in the remaining supply section perform an idle operation. For this reason, unnecessary swinging motion of the cutter causes wear problems, making maintenance of the cutter difficult.

In view of the above points, the present invention provides a supply section that is movable between a first position where continuous cut pieces of electronic components can be supplied to the pallet and a second position where the supply section is separated from the pallet. To provide an electronic component transfer device that eliminates wasteful swinging motion of the cutter and facilitates maintenance of the cutter by making the cutter of the supply section operable only when the supply section is in the first position. It is something.

Embodiments of the electronic component transfer device according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show the overall configuration of the embodiment, and show the state in which it is incorporated into an automatic insertion device. In these figures, the electronic component transfer device 1 has an intermittent running endless belt mechanism in which a chain 3 is stretched between sprockets 2A to 2D, and pallets 4 are fixed on this chain 3 at equal intervals. . Each pallet 4 holds a series of electronic component pieces obtained by cutting the series of electronic components 7 into pieces each containing one electronic component. Along the linear running portion of the chain 3, that is, the straight running portion of the pallet 4, supply sections 5 are arranged at equal intervals with the pallet 4, and each supply section 5 is capable of rotating a reel around which a series of electronic components 7 is wound. A series of electronic components pulled out from the package 6 housed in the housing are connected. In this case, the packages 6 are also arranged at the same intervals as the supply section 5, and the electronic component series 7 pulled out from the package 6 are drawn out to the supply section 5 as they are without twisting or the like. At this time, the drawer length of the electronic component series 7 is the same for each package 6.

The automatic insertion device includes, in addition to the electronic component transfer device 1, a chuck 10 that clamps the electronic components of the electronic component serial cut pieces transferred by the electronic component transfer device 1, a rotary disk 11 on which the chucks 10 are provided at equal intervals, and a chuck 10. It is provided with an insertion section 13 for inserting the lead wire of the electronic component selected in the above into the printed circuit board on the XY table 12.

Details of the pallet 4 and supply section 5 in the electronic component transfer device 1 are shown in FIGS. 3, 4, and 5. In these figures, the pallet 4 is fixed to the chain 3 at the pallet body 20, and a component holding portion 22 is pivotally attached to a hinge portion 21 projecting laterally of the pallet body 20 by a pin 23. The component holding section 22 is provided with a holding claw 24, and the holding claw 24 is urged by a spring 25 so as to come into pressure contact with the upper surface of the component holding section 22. In addition, the pallet body 20 can be moved to the slide bar 26.
is slidably penetrated through the slide bar 26.
A pin 28 protruding from the lower surface of the component holding portion 22 is adapted to engage with the groove 27 at the tip. An extension spring 30 is provided between the pin 29 at the rear end of the slide bar 26 and the pallet body 20, and as a result, the slide bar 26 is in a state of protruding forward, that is, the component holding portion 22 is not attached to the pallet body 20. remain parallel. In this state, the supplying section 5 performs an operation of cutting the electronic component series 7 into one electronic component and supplying the electronic component series cut pieces 40 onto the component holding section 22 .

The supply unit 5 includes a pitch feeder 50 that intermittently delivers a fixed amount of electronic component series 7, and a cutter 5 that cuts the electronic component series 7 to create electronic component series cut pieces 40.
1. The pitch feed wheel 50 is pivotally supported by the supply section frame 52 and has a ratchet mechanism, and rotates by a certain amount with one extension movement of the cylinder 53. The cutter 51 has a tip block 54 fixed to the supply section frame 52 which is pivotally mounted, and performs a cutting operation between the cutter 51 and a fixed blade 55 fixed to the tip surface of the tip block 54. The height of the fixed blade 55 is set to match the height of the component holding section 22 of the pallet 4. The supply section frame 52 in which the pitch feed wheel 50, cutter 51, etc. are assembled in this manner is integrally connected to a driven rotation member 58 which is pivotally connected to the main body frame 56 by a pin 57. An extension spring 59 is provided between the supply section frame 52 and the main body frame 56, and the direction in which the supply section frame 52 is closely opposed to the pallet 4, that is, the direction in which the continuous cut pieces 40 of electronic components can be supplied to the pallet 4 is adjusted. It is biased in the direction of position 1 (the position shown in FIG. 4). In addition, the driven rotation member 5
A contact block 60 is fixed to the cylinder 8, and a cylinder 62 having a shaft 61 that can be engaged with the contact block 60 is fixed to the main body frame 56 side. This cylinder 62
is a single-acting cylinder that retracts only when it is in operation, and when it is not in operation, the shaft 61 is extended and engages with the abutment block 60 as shown in FIG. 2 position state.

On the other hand, a plate-shaped driving rotation member 70 is pivotally attached to the main body frame 56 with a pin 71 in common proximity to the driven rotation member 58 of each supply section 5 . This drive rotation member 70 is connected to one end of a lever 73 via a link 72, and the other end of the lever 73 is connected to the main body frame 5.
The pin 75 is engaged with a pin 75 erected on a slide shaft 74 that is slidable on the slide shaft 74 . Therefore, the slide shaft 74
The driving rotating member 70 rotates due to the sliding movement of the pallet 4, and during the traveling period of the pallet 4, the driven rotating member 58 of each supply section 5 is tilted to the right as shown in FIG. Set it to the second position where it left off.

A cutter operating bar 80 is disposed in common with the cutter 51 of each supply section 5, and a long pin 81 and a short pin 82 are fixed to the cutter operating bar 80 as shown in FIGS. 6 to 9. A stopper pin 83 is fixed to the side.

Next, the operation of the above embodiment will be explained. The pallet 4 executes an intermittent running operation due to the intermittent rotational movement of the sprockets 2A to 2D. When the pallet 4 is at the stop position facing the supply section 5, the supply section 5 to which the electronic component series 7 of a predetermined type is connected is selected. This selection operation is performed by actuating the cylinder 62 of the selected supply section 5. That is, while the pallet 4 is stopped, the drive rotation member 70 is in a position rotated to the left and does not interfere with the movement of the driven rotation member 58, so the cylinder 62 operates and its shaft 61 is rotated. When retracted, the abutment block 6 of the driven rotation member 58
0 and the supply frame 52 is disengaged from the fourth
As shown in the figure, it is closely opposed to the pallet 4. In this way, the supply section 5 supplies the electronic component continuous cut pieces 4 to the pallet 4.
When the pitch reaches the first position where 0 can be supplied, the cylinder 53 is actuated to rotate the pitch feed wheel 50 by a certain amount via the ratchet mechanism, thereby cutting the electronic component chain 7 into a length corresponding to the electronic component continuous cut piece 40. The pieces are fed into the parts holding section 22 of the pallet 4. At this time, the lower end of the cutter 51 is sandwiched and engaged with the long pin 81 and the short pin 82 at the positions indicated by the dashed lines in FIGS. 7 and 8, so that the cutter operating bar 80
By moving to the left, the long pin 81 and the short pin 8
2 moves to the position shown by the solid line, the cutter 51 rotates and closes as shown in FIG. In this case, the electronic component series 7 are supplied to the pallet 4 in the order in which they are inserted into the printed circuit board.
The electronic component continuous cut pieces 40 are arranged on top. The electronic component continuous cut pieces 40 are held on the component holding portion 22 by being pressed by the holding claws 24.

On the other hand, in the remaining supply units 5 that are not selected,
The shaft 61 of the cylinder 62 remains engaged with the abutment block 60, and the feed section 5 is maintained in its second position separated from the pallet 4, as shown in FIG.
In this case, the positional relationship among the long pin 81, short pin 82, and stopper pin 83 is as shown in FIG. Since the engagement of the cutter 51 is disengaged, the cutter 51 maintains the open state shown in FIG.

The electronic component continuous pieces 40 held by the component holding section 22 of the pallet 4 are sequentially transferred toward the chuck 10 as the chain 3 runs intermittently.

As explained above, according to the electronic component transfer device of the present invention, an endless belt mechanism that travels intermittently, a plurality of pallets provided on the endless belt mechanism, and continuous cut pieces of electronic components are supplied to the pallets. and a plurality of supply sections, in the case where the continuous cut pieces of electronic components are held and transferred by the pallet, the supply section is arranged between a first position where the continuous cut pieces of electronic components can be supplied to the pallet and a position where the continuous cut pieces of electronic components can be supplied to the pallet. By making the cutter of the supply section operable only when the supply section is in the first position, unnecessary swinging motion of the cutter can be eliminated. , maintenance of the cutter is facilitated, and reliability can be improved.
