DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in conjunction with an automatic electronic component mounting apparatus for mounting chip-type electronic components on a printed circuit board. The present invention relates to a chip-type electronic component supply device for supplying chip-type electronic components one by one.

[0002]

2. Description of the Related Art A conventional chip-type electronic component supply apparatus of this type will be described with reference to the drawings.

FIG. 11 is a perspective view of a main part showing a storage case 30 mounted on a conventional chip-type electronic component supply device and a detachable portion thereof. The storage case 30 is 36 mm wide × 12 mm thick × high according to the EIAJ standard. The bottom 35 is provided with a discharge port 36 for discharging chip-type electronic components, and a shutter 31 for closing the discharge port 36, and a portion of the bottom 35. A recess 32 and a slide rail 33 are formed in the recess.

The chip type electronic component supply device in which the storage case 30 is mounted is provided with a slide groove 37 that engages with a slide rail portion 33 provided in the storage case 30. The storage case 30 is joined by inserting the slide rail portion 33 in the direction of the arrow in the figure.

[0005]

However, in the above-described conventional chip-type electronic component supply device, when handling large-size chip-type electronic components, the storage capacity of the storage case 30 mounted on the device is reduced. Since the number of replacements of the chip-type electronic component supply device or the storage case 30 is increased and the chip-type electronic components cannot be supplied continuously for a long time, a large-sized storage case having an increased storage capacity of the chip-type electronic components is required. There was a problem that it was necessary.

In the case where a plurality of chip-type electronic component supply devices equipped with the conventional storage case 30 are arranged adjacent to the supply unit of the electronic component automatic mounting device, the storage case is small when the arrangement pitch is small (for example, 16 mm). Since there is only a 4 mm gap between adjacent 30s, and to take out only the storage case 30, it is necessary to lower the hand from above and grab the narrow (12 mm wide) surface of the storage case 30 and take it out. There is a problem that the provided slide rail portion 33 is difficult to remove because it is pryed by the groove 37 of the chip-type electronic component supply device.

Further, when the above-mentioned large storage case is required, the width of the storage case is increased, and the space between the storage case and the adjacent storage case is reduced, so that the storage case can be easily attached and detached. As a result, there has been a problem that the downtime of the chip-type electronic component supply device is extended, and the productivity is significantly reduced.

[0008]

In order to solve the above-mentioned problems, a chip-type electronic component supply device according to the present invention is provided so as to face a side surface of a storage case in which a plurality of chip-type electronic components are stored in a loose state. A storage case holding portion that fits into the recess to hold the storage case, a swinging automatic storage case extraction lever that has one end engaged with a concave engagement portion provided on the bottom surface of the storage case, and the storage case A first conveying means for aligning and conveying the chip-shaped electronic components one by one in communication with the opening provided in the first conveying means, and a second conveying means for conveying the chip-shaped electronic components conveyed by the first conveying means to the take-out section It is a structure which consists of.

According to the present invention, even if the conventional storage case is enlarged and the space between the arrangements of the chip-type electronic component supply devices is narrowed, the storage case can be moved to the chip-type electronic component supply device by using the storage case take-out lever. Since attachment and detachment can be easily performed, the stop time of the chip-type electronic component supply device can be reduced, and productivity can be improved.
