Description

[Detailed description of the invention] This invention relates to a container for chip-type electronic components such as multilayer capacitor chips, resistor chips, jumper wire chips, transistor chips, etc., and is particularly suitable for automatic mounting on printed circuit boards. The present invention relates to an improved structure of a storage body to realize a feeding form.

In the automatic mounting method, conventional methods for supplying chip-type electronic components include those using a vibrating parts feeder, those using a flat magazine, and the tape method.
In the case of a vibrating parts feeder, only 111 ffl of chips can be supplied by one parts feeder, so there is a capacity limit.

Also, it takes up a lot of space.

Also, the reliability or reliability of chip supply is poor.

Furthermore, there is a drawback that if a small amount of chips remain in the parts feeder, it becomes impossible to supply the chips.

FIG. 1 is a perspective view of a conventional magazine.

The magazine 1 shown here is a flat type, made of aluminum or plastic, and has a fixed length.

In this magazine 1, a plurality of chip type electronic components 2 are stored in a two-dimensional arrangement.

The machining method using such a magazine 1 is inefficient because it is necessary to determine the positional relationship between the magazine 1 and the printed circuit board or the like to be mounted.

There is also a method in which a plurality of magazines 1 are set in advance at fixed positions on a predetermined plane, but the setting work is complicated.

Furthermore, since the magazine 1 is of a flat type, it has the disadvantage that it occupies a large amount of space.

FIG. 2 is an illustrative diagram of a conventional tape system.

A plurality of chip-type electronic components 2 are temporarily held on a tape 3 at equal intervals.

Then, the chip type electronic component 2 is placed on the printed circuit board 4.
is supplied together with the tape 3. Chip type electronic components 2 are mounted one by one on a printed circuit board 4.

This method has the disadvantage of being limited in capacity and having poor work efficiency since only one chip type electronic component 2 is supplied.

Further, in the three methods described above, when the board type (circuit) is changed, it is necessary to change the supply unit for each chip or change the sequence using an expensive device such as a numerical control device.

Therefore, the main purpose of this invention is to provide a housing for chip-type electronic components suitable for automatic mounting.

Another object of this invention is to provide a storage body for chip-type electronic components that can be applied to an automatic mounting method in the form of shipment from a component manufacturer and can realize such a shipping condition.

Other objects and features of this invention will become clearer from the detailed description given below with reference to the drawings.

FIG. 3 is a perspective view of a state in which parts are being supplied using a storage body according to an embodiment of this invention.

FIG. 4 is a plan view showing a magazine advantageously used in the storage body of FIG. 3.

The storage body 10 includes an outer case 11 having a square cylindrical shape, for example.

The upper end surface of the outer case 11 is an opening.

The outer case 11 is provided with partition walls 12 arranged in a grid pattern, thereby forming a plurality of partition walls 13.

The compartment 13 has, for example, a square cross section, and is formed to extend from the upper end opening to the lower end of the outer case 11.

Such an outer case 11 is made of, for example, an aluminum alloy.

A magazine 14 is housed in the compartment 13 described above.

The magazine 14 is formed with an H-shaped cross section, and can be used, for example, for drawing aluminum alloy, molding or cutting plastic, etc.
Obtained by cutting or machining iron.

As shown in FIG. 4, the magazine 14 has a square cross-sectional dimension, with the length a and the width being equal.

brought about by the H-shaped cross section of the magazine 14.
A housing portion 15 that matches the dimensions of the chip-type electronic component 2 is formed in the recess.

The storage section 15 can have any size and position within the range of the external dimensions a and b of the magazine 14.

Therefore, various magazines 1 having the same external dimensions asb
4 can accommodate and position chip-type electronic components 2 of various sizes.

The chip type electronic component 2 is stored in the storage section 15 of the magazine 14.
Multiple pieces are stored in a stacked state in the longitudinal direction.

It should be noted that electrodes serving as external terminals are formed at appropriate positions on the power tip type electronic component 2 (not shown).

The magazine 14 containing a plurality of chip-type electronic components 2 as described above is inserted in the longitudinal direction from the upper end opening of the external case 11 and housed in the compartment 13, as shown in FIG.

In order to maintain the stored state of the magazine 14, an appropriate locking means (not shown) is provided at the lower end of the outer case 11, so that at least a push-up pin 20o, which will be described later, can be inserted. ing.

As described above, the magazine 14 is housed in the compartment 13, so that it can be positioned in rows and columns within the external case 11, and chip-type electronic components 3 housed in the magazine 14 can be prevented from falling off in the lateral direction. can be prevented.

Since the cross-sectional shape of the magazine 14 is square,
The direction can be changed by 90° relative to the compartment 13.

This means changing the direction of the six-chip electronic component 2.

The automatic mounting process will be described with reference to FIG.

First, the chip type electronic component 2 is selected according to the circuit design, and the magazine 14 is prepared accordingly.

Then, the magazine 14 is inserted into a desired compartment 13 of the outer case 11 and stored in a desired direction.

Then, this outer case 11 is positioned on the push-up pin 20 that presses a part of the supply device.

These push-up pins 20 push up the chip-type electronic components 2 in the magazines 14 housed in the compartments 13 from below, and a plurality of push-up pins are provided corresponding to each compartment 13.

The push-up pins 20 are planted in a row on the push-up plate 21.

A rack 22 is provided on the lower surface of the push-up plate 21,
This rack is guided by guide rollers 23 and moved up and down by a pinion 24 which is rotationally driven σ.

In this way, as the rack 22 moves upward, the push-up pin 20 moves upward via the push-up plate 21.

In response to this, the chip-type electronic components 2 in the magazine 14 rise one by one.

At this time, the chip type electronic component 2 located at the uppermost position is
For example, they are each chucked by a pickup unit (not shown) using a vacuum, carried to a position on a printed circuit board (not shown) that has been finger-pressed in advance, and mounted.

In the above embodiment, since the compartment 13 and the magazine 14 have a square cross-sectional shape, the storage direction of the magazine 14 can be changed by 900 degrees.

Therefore, there is an advantage that the direction of the chip-type electronic component can be changed as well.

However, even if the cross-sectional shapes of the compartment and magazine are made rectangular, for example, by changing the shape of the magazine (including the shape of the storage section 15), the position of the chip-type electronic components to be stored, as well as the Since the storage direction can be changed, the cross-sectional shapes of the compartment and magazine are not limited to square shapes.

Incidentally, magazines suitable for chip-type electronic components of various sizes have been prepared, but if the dimensions of chip-type electronic components are standardized, only one type of magazine will be needed, and costs can be reduced.

In addition, as shown in FIG. 3, when a plurality of push-up pins 20 are held on one push-up plate 21 and push up the chip-type electronic component 2 at the same time, the thickness dimension of the chip-type electronic component It is best to aim for a standard rate.

However, if the configuration is such that the individual push-up pins 20 can be driven separately, this is not necessary.

For example, in the external case 11 shown in Fig. 3, the partition walls 12 are formed at equal pitches, but if you want to arrange magazines at different pitches using such an external case 11, you need to change the cross-sectional dimensions of the magazines. Additionally, the magazine may be positioned by inserting an appropriate spacer.

In this case, the push-up pins may also be converted accordingly.

As described above, according to this invention, a housing for chip-type electronic components suitable for automatic mounting can be obtained.

According to this container, it is possible to mount multiple chip-type electronic components of different types at the same time, and if such a container is prepared in advance with electronic components stored in it, it will be easier to replace the product type. Even if there is, the process can be carried out efficiently by replacing the storage body with a single touch and also replacing the pick-up unit's pick-up head in the same way.

In addition, this storage body can also be used when shipping from a parts manufacturer, and if chip-type electronic components are appropriately stored in consideration of the subsequent mounting process, it can be applied to the automatic mounting process. can do.

In addition, automatic mounting has been realized that is suitable for medium-sized mass-produced products such as this storage body &-3 consumer radio, and it is possible to reduce the cost of mounting, as well as reduce the cost of parts and make the storage state smaller. It's useful.

Usually, the magazine has an H-shaped cross section, and therefore the storage section formed therein has a wide opening, so that during the process of preparing the magazine to be stored in the external case, Insertion of multiple electronic components into the magazine can be easily performed.

And, Tonoyo 5. When storing chip-type electronic components, each chip-type electronic component can be carried to its storage position in the magazine while maintaining its storage orientation, so that multiple chip-type electronic components can be stored in one place in the magazine. There is no room for misalignment of stacking of electronic components, and if necessary, the stacking status of multiple electronic components in the magazine can be visually confirmed, which completely prevents the occurrence of undesirable stacking status. It has the effect of preventing

Furthermore, if the magazine L has an H-shaped cross section, the recess created by this H-shaped cross section is ■1! Two pieces will be formed for magazine I.

Therefore, by changing the size and shape of the two-barreled recess, it is possible to have two types of storage compartments for a li-rig magazine, and an 11-bar magazine can be
It can be used to store various types of chip-type electronic components.

Furthermore, it is also possible to use an 11-piece magazine to store two types of chip-type electronic components at the same time.
