1, and 104 is a position adjustment claw that adjusts the position of the chip component 101 at the center of the nozzle 103.

Reference numeral 105 denotes a transfer section that includes the nozzle 103 and is supported so as to be movable up and down and back and forth.

106 is a board on which the chip component 101 is mounted, and 107 is a support stand that supports the board 106.

In the above configuration, the chip parts 101 that are aligned and fed by the vibrating feeder 102 are attracted to the tip suction surface of the nozzle 103 by the suction operation of the nozzle 103, and while the transfer section 105 moves to the mounting position of the substrate 106, The position is regulated by a position regulating claw 104.

However, in the conventional example described above, it is possible to adjust the position during the transfer operation of the chip component 101, but it is necessary to check whether the position adjustment is performed correctly or to check whether the chip component 101 has a predetermined shape. It also has the disadvantage that it is not possible to simultaneously detect whether the chip component 101 has unique electrical characteristics.Also, it is conceivable to provide an inspection station in the middle, but there is a problem that it cannot be applied to electronic components of various shapes. It had

The present invention solves the above-mentioned conventional drawbacks,
The embodiment will be described below based on FIGS. 2 and 3.

1 is a chip part; 2 is the chip part 1;
It is a vibratory feeder that aligns and feeds. 3 supports the plurality of vibrating feeders 2, and a threaded rod 4
Vibrating feeder 2 is a table that can be moved horizontally in the direction of arrow E in FIG. 3 by a drive motor 5.
Together, they form a parts supply section.

7a, the chip component 1 is suctioned and taken out from the chip component supply position A-A, and the chip component 1 is taken out from the chip component regulation position B-B.
7b is a nozzle for transferring the chip component 1 from the chip component regulation position BB to the device position CC. Chip parts supply position A-A and chip parts regulation position B-B
The distance between the chip component regulation position BB and the chip component device position CC are equal.

8 supports the nozzles 7a and 7b at a pitch equal to the distance between the chip component supply position A-A and the chip component regulation position B-B, and
This is a transfer unit that moves back and forth and up and down in the order of →J→K→L→M→L→K. Here K is the initial position,
J is the supply position and M is the mounting position.

Reference numeral 9 positions the chip component 1 that has been suctioned and transferred from the vibration feeder 2 by the nozzle 7 in the mounting direction, molds the lead into a mini-mold type transistor chip component, etc., and further molds the chip component 1's unique characteristics. This is an intermediate station that simultaneously checks the electrical characteristics of both.

Reference numeral 10 denotes a regulating block for positioning, molding, and checking electrical characteristics of the chip component 1.
Reference numeral 11 denotes a rotary plate for rotating the regulated chip component 1 in the mounting direction, and the rotary plate 11 is rotated by a predetermined angle by a servo motor 13 via a belt 12.

As shown in FIG. 3, a rotary plate equipped with a regulating block 10 constitutes a means for regulating the position of electronic components in the present invention.

Reference numeral 14 denotes a TV camera, which displays the positioning status of the chip component 1 on a monitor television 15, and uses pattern recognition to reconfirm and correct the positioning accuracy.

Reference numeral 16 is a hole that can be opened and closed, and if a defective product with misalignment or poor characteristics is found again through pattern recognition, the defective chip part 1 is inserted into the hole 16.
drop it down.

Reference numeral 17 denotes a movable table, which is movable in the direction of arrow F in FIG. 3 to enable selection of a plurality of rotary plates 11a, 11b, which are position regulating means, according to the shape of the chip component 1.

18 is a threaded rod for horizontally moving the moving table 17 in the direction of arrow F, and 19 is a drive motor connected to the threaded rod 18.

Reference numeral 20 denotes a table that supports the substrate 6 and relatively changes the mounting positional relationship with the nozzle 7b, and is capable of horizontal movement simultaneously in the direction of arrow G and the direction of arrow H in FIG. 3, and constitutes a substrate support section. are doing.

Next, the operation will be explained.

The chip parts 1 that are aligned and fed by the vibrating feeder 2 are sucked by the nozzle 7a at the chip part supply position A-A of the vibrating feeder 2, and are sucked by the nozzle 7a by the vertical movement and back-and-forth movement of the moving part 8.
It is placed at the center of a rotary plate 11a provided on the intermediate station 9. In synchronization with this operation, the chip component 1, which has already been positioned and checked for characteristics at the intermediate station 9, is sucked by the nozzle 7b and mounted to a predetermined mounting position on the board 6. The intermediate station 9 is provided with a plurality of rotary plates 11a and 11b so as to enable positioning and characteristic checking of chip parts 1 of a plurality of shapes. This is done during the transfer operation.

By performing the above basic movements continuously,
Positioning, molding, and characteristic checking of the chip part 1 can be performed within the time of the mounting operation.

As described above, according to the present invention, an intermediate station is provided between the chip component supply unit and the mounting board, and by moving two nozzles between the front and back, the position of the chip component can be adjusted at the intermediate station. It can be done without wasting time.

In addition, the intermediate station is provided with a plurality of regulating parts so that the positions of chip parts having different shapes can be simultaneously adjusted.
You can check the unique electrical characteristics and set the mounting angle at the same time.
