More specifically, a taper portion 63 is formed on the opening / closing lever 61, and in the standby state shown in FIG. 4, the component holding member is pushed by the taper portion 63 along a guide (not shown). The chip component 3 of the next order is held by the holding pin 65 of 64, and the chip component 3 at the take-out position at the tip is locked by the stopper 66 fixed to the main body of the supply device. Then, when the opening / closing lever 61 swings clockwise through the second transmission lever 31 and the link piece 34 due to the lowering of the actuator arm 11, the engagement between the tapered portion 63 and the holding member 64 is released, and The holding pin 65 is separated from the next-ranked chip component 3 by the spring 67, and the shutter 60 opens the component take-out port.

The component supply device 1 includes a lift-up handle 70 and a lock lever 7 arranged at the rear of the main body of the device.

With the above configuration, the following operation is shown in FIG.
This will be described with reference to the timing chart of No. 0. First, the state shown in FIGS. 1 and 4 is a standby state, that is, the actuator arm 11 of the chip component automatic mounting apparatus is in the ascending limit position, and the chip component 3 at the tip position (component removal position) and the chip component in the next order. Separation from 3 (escape)
The holding pin 65 of the holding member 64 presses and holds the next chip component 3 in the next order, and the chip component 3 at the tip position is locked by the stopper 66.

When the actuator arm 11 of the automatic chip component mounting apparatus descends, the lower end of the arm 11 lowers the actuating lever 15 and swings the first transmission lever 17 counterclockwise about the spindle 16 as a fulcrum. To move. Then, the swing of the first transmission lever 17 causes the pin 21 to swing the alignment lever 20 about the support shaft 22 as a fulcrum,
The actuating member 24 is raised via the spring 23 to rotate and raise the eccentric pin 25, thereby actuating the aligning device 6.

Further, as shown in FIG. 2, when the actuator arm 11 descends by a predetermined distance, the actuating lever 15 also descends and the second transmission lever 31 with the support shaft 32 as a fulcrum.
Also at this time swings clockwise. Therefore, the roller 59 provided on the link piece 34 moved to the front portion on the sending side by the swing of the second transmission lever 31 contacts the opening / closing lever 61 of the shutter 60, and the support shaft 62 serves as a fulcrum to rotate the roller 59 clockwise. The opening / closing lever 61 is rotated. The upper end of the opening / closing lever 61 and the shutter 60 that covers the upper portion of the conveyor belt 42 are integrated, and the shutter 60 moves and takes out when the opening / closing lever 61 rotates clockwise as shown in FIG. The suction nozzle 10 that opens the opening and lowers the chip component 3 that is separated and located at the leading edge (component extraction position)
Is sucked (chucked), taken out from the component supply device 1, and mounted on a printed circuit board (not shown).

Further, as described above, the operating lever 15
When the second transmission lever 31 swings in the clockwise direction due to the downward movement, the link piece 34 moves to the left and the feed lever 3
Since 6 rotates in the clockwise direction, the feed claw 40 also rotates and moves so as to cross the predetermined number of teeth of the feed gear (not shown).

As described above, the leading edge chip component 3 is separated (escape) by the holding pin 65 of the holding member 64.
When the actuator arm 11 and the operating lever 15 are lowered from the standby state held in the opened state, the second transmission lever 31 swings in the clockwise direction to rotate the opening / closing lever 61 in the clockwise direction to release the shutter. 60 is moved to open the take-out opening, and the suction nozzle 10 is lowered.
Is to pick up the chip component 3 by suction (chuck) (see FIGS. 2 and 5).

When the actuator arm 11 starts to move up after the chip component 3 is taken out as shown in FIG. 6, the operating lever 15 also starts to move up.
1 rotates counterclockwise, the link piece 34 moves to the right, the opening / closing lever 61 swings counterclockwise, the shutter 60 is moved to start closing the take-out opening, and the taper portion 63 is held. It abuts the member 64 (see FIG. 7). When the link piece 34 moves to the right, the feed claw 40 rotates the feed gear by rotating the feed lever 36 in the counterclockwise direction, and the pulley 41 rotates in the counterclockwise direction. The chip component 3 starts to be conveyed via the conveyor belt 42 via the pulleys 41, 43, 46, 47 (see FIG. 7).

When the actuator arm 11 further rises, the link piece 34 moves further to the right as shown in FIGS. 3 and 8, and the shutter 60 is taken out by swinging the opening / closing lever 61 in the counterclockwise direction. When the opening is closed and the tapered portion 63 presses the holding member 64, the holding pin 65 abuts and holds the chip component 3 adjacent to the chip component 3 to be taken out next (see FIGS. 3 and 8).

Eventually, by further moving the link piece 34 to the right, the contact of the roller 59 with the opening / closing lever 61 is released, and the holding pin 65 is adjacent to the adjacent chip component 3.
The chip component 3 to be taken out at the front end position is conveyed via the conveyance belt 42 while holding the above (see FIG. 9). At this time, the chip component 3 to be taken out at the tip position is locked to the stopper 66 and is restricted from moving further than that.

After the contact of the roller 59 with the open / close lever 61 is released, the actuator arm 11 further rises and then stops, and the feed lever 36 also stops. Therefore, the conveyance by the conveyance belt 42 is stopped and the initial state is set. It will be restored (see FIG. 4).

Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention can be carried out in various ways without departing from the spirit of the invention. It is intended to cover alternatives, modifications or variations.
