Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a magazine case for chip-shaped electronic components (hereinafter referred to as "chip components"), which stores chip components in a form that is easy to automatically mount. This relates to magazine cases.

Conventional configurations and their problems In recent years, chip components have come into widespread use due to the miniaturization of electronic devices and advances in automatic mounting technology.

A magazine case for chip components consists of a cylindrical magazine case body that stores a large number of stacked chip components, a stopper that is movable within the magazine case body to prevent chip components from falling out, and a chip mounted at the tip of the magazine case body. It is composed of a leaf spring that presses the component against the inner wall of the magazine case body to prevent the chip component from falling off.

After screwing into the automatic mounting machine, push the stopper with a push rod linked to the automatic mounting machine, push up the chip parts one by one, and automatically mount them at the specified position on the printed circuit board. be.

Hereinafter, a conventional magazine case for chip components as described above will be explained with reference to the drawings.

FIG. 1 shows a conventional magazine case for storing chip components. In FIG. 1, reference numeral 1 denotes a magazine case body, and 2 denotes a leaf spring that presses the chip components against the inner wall of the magazine case body to prevent the chip components from falling off.

Figure 2 shows a cross section of a magazine case in which a large number of chip parts are stacked and housed.
3゜3a and 3b are chip components, 4 is a stopper that is movable within the magazine case body to prevent the chip components from falling off, and 1a is a chip component removal 1]. After setting it in the automatic mounting machine, a push rod linked to the automatic mounting machine pushes up the stopper 4, and the chip part 3a is pushed up against the leaf spring 2.
The structure is such that the pieces are sent out one by one from the outlet 1a.

However, in the above configuration, a phenomenon occurs in which the chip components 3 come into close contact with each other due to the load when pushing up the chip components 3. Outlet port 1ajt),
One piece at a time is sent out reliably (B-j'- There are cases where two or more pieces are sent out at the same time, which causes a problem in mounting abnormalities.

Purpose of the Invention In view of the above-mentioned drawbacks of the conventional art, the present invention provides a method for removing chip parts one by one from the magazine case outlet. The present invention provides a magazine case for chip components that can be accurately and reliably fed out and automatically loaded.

Structure of the Invention The magazine case for chip components of the present invention has one or more elastic protrusions formed in the chip component take-out portion of the magazine case, and when the chip components pass through the protrusions, the chip components are removed. The close contact between them is forcibly removed, and 1
It can be reliably sent out one by one.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

Figure d shows a magazine case for a Chippa IX product according to an embodiment of the present invention, and Figure 4 is a partial cross-sectional view of the same embodiment with chip components stored in the magazine case. It is.

In FIGS. 3 and 4, 1 is the magazine case body, 2 is the plate spring, 3, 3a and 3b are the chip parts, 4 is the stopper, and 1a is the take-out 1.

The above configuration is the same as the configuration of the conventional 1/0 shown in FIGS. 1 and 2. Numerals 6 and 6 are resilient protrusions provided perpendicular to the leaf spring 2, which forcibly separate the chip components 3 in close contact with each other. A push rod interlocked with the mounting machine pushes up the tool 4, and the chip component 3 is pushed up to the ejector 111a. At this time, when the chip component 3a passes through the elastic protrusions 6 and 6, it is forcibly separated from the chip component 3b, and the chip component 3a is forcibly separated from the chip component 3b.
will be sent to.

In this embodiment, the elastic protrusions 5 and 6 are integrally formed with the magazine case body and are provided at two locations, but the suspended matter may be different from the magazine case body, for example, metal, brass, or resin. , rubber may be used.

There is no doubt that the number and shape of the grooves and protrusions are not limited to those in this embodiment.0 As described above, the present invention provides elasticity at the ejection portion of the magazine case for chip components. Providing the protrusion 171S having a diameter can reliably prevent two or more chip components from being sent out at the same time due to the close contact between conventional chip components, and significantly reduce the mounting rate during mounting.
It becomes possible to do 1.

Its practical effect is that of a dog.
