Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a chip-type electronic component storage magazine that stores chip-type electronic components and is attached to an automatic mounting machine to mount the chip-type electronic components onto a printed circuit board. be.

Conventional configuration and its problems Figure 1 shows the configuration of a conventional chip type electronic component storage magazine.
This will be explained with reference to FIG. FIG. 1 shows a conventional chip-type electronic component storage magazine. Reference numeral 1 indicates a magazine body having a square cross section and a regular quadrangular prism shape with a hollow portion. 2 is a leaf spring attached near the tip of the magazine body 1, and 3 is a chip-shaped electronic component housed in a stacked state in the hollow part of the magazine body 1.

The chip type electronic component storage magazine consisting of the magazine body 1 and the leaf spring 2 is attached to an automatic loading machine, and the chip type electronic components 3 stored in the hollow part of the magazine body 1 are inserted from the bottom of the hollow part of the magazine body 1. It is pushed up with a push rod and attached to the printed circuit board. Fig. 2 is a view of the above-mentioned chip type electronic component storage magazine installed in the automatic mounting machine as seen from the printed circuit board side, and shows 1a, 1b, 1c.
3 is a magazine body, 3a, 3b, and 3c are chip-type electronic components, and 4 is a holder for fixing the magazine.

As shown in FIG. 2, magazine bodies 1a and 1b.

Since 1C has a square cross section, the housed chip-shaped electronic components 3a, 3b, and 3c can be arranged at regular intervals at angles different from each other by 90 degrees.

Therefore, the conductor pattern of the printed circuit board must be designed so that the chip-shaped electronic components 3 are arranged at regular intervals in the same direction or at angles different from each other by 90 degrees.

As described above, when a conventional chip-type electronic component storage magazine is used, the degree of freedom in designing the conductor pattern of the printed circuit board is limited to arranging the chip-type electronic components in the same direction or at most 9
They were only allowed to be arranged in directions that differed by c degrees, which was extremely restrictive.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a chip-type electronic component storage magazine which can eliminate the above-mentioned conventional disadvantages and greatly increase the degree of freedom in designing the conductor pattern of a printed circuit board.

Structure of the Invention The chip-type electronic component storage magazine according to the present invention has a hollow prismatic shape with a regular octagonal to dodecagonal cross section.

Description of examples An embodiment of the present invention will be explained with reference to FIGS. 3 and 4.

Reference numeral 5 denotes a prismatic magazine body made of resin and having a regular octagonal cross section and a hollow portion. Reference numeral 6 denotes a leaf spring attached near the tip of the magazine body 6, which is either made of metal and fixed to the magazine body 5, or made of resin and molded integrally with the magazine body 5. Reference numeral 7 designates chip-type electronic components stored in a stacked state in the hollow portion of the magazine body 6. The chip type electronic component storage magazine consisting of the magazine body 6 and the leaf spring 6 is attached to an automatic mounting machine, and the chip molded parts stored in the hollow part of the magazine body 5 are inserted into the hollow part of the magazine body 5. It is pushed up from the bottom with a push rod and attached to the printed circuit board. In this case, the plate no. 6 is a chip engraving located at the leading edge of the magazine body 5.

The inner wall of the hollow part of the magazine body 6 is pressed while holding down the side surface of the knob-shaped electronic component 7 stored adjacent to the knob-shaped electronic component 7 located at the tip end of the magazine body 6 without holding down the child component 7. The position of the plate spring 6 is set so that it comes into pressure contact with the plate spring 6.

As a result, even when the chip-shaped electronic components 7 housed in the magazine body 6 are pushed up by the push rod, only the chip-shaped electronic components 7 located at the leading edge are always mounted on the printed circuit board, and other chip-shaped electronic components 7 are always mounted on the printed circuit board. The electronic components 7 are prevented from popping out of the magazine body 5 at the same time.

FIG. 4 is a view of the chip type electronic component storage magazine mounted on the automatic mounting machine, viewed from the printed circuit board side. That is, it is a view seen from the tip of the chip-type electronic component storage magazine. 5a, 5b.

5c and 5d are the magazine bodies, 7a and 7b.

7C97d has magazine bodies 5a, 5b, 5c, respectively.
.

It is a chip-shaped electronic component housed in 5d. Further, 8 is a holder having regular octagonal holes provided at equal intervals, and the magazine bodies 5a, 5b, 5c, and 5d are inserted into the holes of the holder 8 and fixed.

Further, the magazine body 5b is rotated 90 degrees counterclockwise with respect to the magazine body 5a and fixed to the holder 8,
The magazine body 5C is rotated 46 degrees counterclockwise with respect to the magazine body 5a and fixed to the holder 8. Further, the magazine body 5d is rotated 45 degrees clockwise with respect to the magazine body 5a and fixed to the holder 8. Therefore, the chip-type electronic components 7b, rC, and 7d can be mounted on the printed circuit board while being rotated 90 degrees counterclockwise and 46 degrees counterclockwise relative to the chip-type electronic component 7a, respectively.

The structure of the present invention is not limited to the embodiment shown in FIG. 2, and the magazine main body may have a hollow prismatic shape with a regular dodecagonal cross section.

Effects of the Invention According to the present invention, the degree of freedom in designing the conductor pattern 7 (7) of a printed circuit board can be greatly increased compared to the conventional method.

When using a conventional chip-shaped electronic component storage magazine with a square cross section, the chip-shaped electronic components are placed at 0 degrees and 9 degrees to each other.
However, according to the present invention, by creating a chip-shaped electronic component storage magazine with a regular octagonal cross section, the chip-shaped electronic components can be mounted on a printed circuit board at six different angles of 0 degrees and 270 degrees. It can be mounted on a printed circuit board at an angle of 0° or a multiple of 45°, and by making it a chip-shaped electronic component storage magazine with a regular dodecagonal cross section,
Can be installed at angles that are multiples of degrees. Therefore, the degree of freedom in designing the conductor pattern of the printed circuit board can be greatly increased compared to the conventional method, and the mounting density of chip-shaped electronic components on the printed circuit board can be greatly improved compared to the conventional method.

Theoretically, if the cross-sectional shape of the magazine body is a regular N-gon with N being a multiple of 4, then it can also be a regular 16-gon, a regular 20-gon, etc.
Although a rectangular shape can be considered, in practical terms, the necessary range for the degree of freedom in the design of the printed circuit board is at most a regular dodecagon, and if the number of squares is made more than a regular hexagon, the insertion angle when inserting the magazine body into the holder will change. Inconveniences such as making mistakes may occur.
