Abstract

PURPOSE:To facilitate the accumulation and extraction of a substrate by fixing a storage part formed out of two surfaces formed out of one plate material which is bent perpendicular, and of an orthogonal floor plate, to a board seat in such a way that the storage part is tilted backward, and by providing a notch for extraction on the floor plate. CONSTITUTION:One plate material is folded at right angles, so as to form back plates 21, 22 perpendicular to each other, and a bottom plate 23 is bonded to the back plates 21, 22 at right angles, so as to form a housing part 2. A long hole 220 is provided on the back plate 22, and the housing condition of a substrate 8 for putting on electronic parts loaded on the housing part 2, is detected by a photocoupler which is not shown in the figure. The bottom plate 23 of the housing part 2 is fixed to a board seat 1 by supporting legs 12, 12' of different lengths, and the housing part 2 is tilted backward by the angle theta, so as to make the long hole 220 faced in the vertical direction. A notch 230 is formed on the bottom plate 23 from the angular part in the diagonal direction. The accumulation or extraction of the substrate 8 can thus be facilitated even when the size of the substrate is different, without using a positioning device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a storage magazine for storing a large number of electronic component mounting boards in a stacked manner.

[Prior art]

Generally, in the manufacturing process of child component mounting boards, a large number of electronic component mounting boards that have undergone a cleaning process and a continuity testing process are temporarily stored in a storage magazine. Then, the storage magazine is sent to the first packing process by hand or by a handling device.

By the way, in a storage magazine for electronic component mounting boards, it is necessary to adjust the width of the storage section in order to accommodate a plurality of types of electronic component mounting boards of different sizes. One example of a storage magazine having such a function is the storage magazine described in Japanese Utility Model Application Publication No. Sho 62-150407.

The storage magazine, as shown in FIG. 7, consists of a base 90 and a storage section 91 provided on the base 90. The storage section 91 has a pair of movable tables 92 that are moved on a base 90 by adjusting bolts 96.

A moving guide plate 93 is erected on both moving tables 92.

Further, a holding guide plate 94 whose interval can be adjusted in a direction orthogonal to the direction of movement is attached to the two-car moving table 92. The holding guide plate 94 is provided with nine long holes 95 for adjusting the spacing.

When in use, preparations such as adjusting the width of the storage section 91 are performed before inserting the electronic component mounting board 8. That is,
As shown in the figure, the distance between the moving guide plate 93 and the holding guide plate 94 is adjusted in advance according to the size of the electronic component mounting board 8. Electronic component mounting board 8
is inputted from the input port 97 provided at the upper part of the storage section 91. At this time, both guide plates 93 and 94 are provided with a slight taper so that the electronic component mounting board 8 can be easily lowered.

[Problem to be Solved] However, in the conventional storage magazine for electronic component mounting boards, it is necessary to make arrangements such as adjusting the width of the storage section to match the size of the child component mounting board.

Then, at the time of loading, it is necessary to precisely align the electronic component mounting board to the loading slot. Also, on the guide plate of the storage section, there is an i! It is necessary to provide a taber to allow the board for mounting electronic components to descend smoothly.

Furthermore, since the width adjustment mechanism of the storage section is required, the structure of the storage magazine becomes complicated, and the manufacturing cost of the storage magazine increases.

SUMMARY OF THE INVENTION In view of these conventional problems, it is an object of the present invention to provide a storage magazine for electronic component mounting boards that has a simple structure and excellent workability.

(Means for solving the problem) The present invention includes a pedestal and a storage section provided on the pedestal,
The storage section is made up of two back plates arranged at right angles and a bottom plate arranged at right angles to the lower parts of the two back plates, and the storage section is tilted backward and fixed to the pedestal. The electronic component mounting board storage magazine is characterized in that the bottom plate is provided with a notch for taking out the stored electronic component mounting board.

What is most noteworthy about the present invention is that the storage section, which consists of a bottom plate having a cutout for taking out and a back plate for alignment, is fixed to the pedestal in a backwardly inclined manner.

In the present invention, the storage magazine is mainly intended for small pieces having a width of 100 mm or less. The electronic component mounting substrates as small pieces include lead frames, printed wiring boards, and the like.

Also, the material of the storage magazine mentioned above is cheap and light.

In addition, it is desirable that the electronic component mounting board used as a storage product not be damaged. Such materials include polyvinyl chloride resin, nylon resin, and the like.

In the present invention, it is desirable that the inclination angle of the storage section is 5 to 30 degrees.

The two back plates of the storage section are arranged in two ways: (1) they are arranged in a substantially V-shape with their end surfaces abutting each other, and (3) they are arranged in a substantially V-shape with a slight gap between the end surfaces. There are cases.

Further, it is preferable that the bottom plate of the storage section is provided with a clamp groove for positioning the clamp of the lifting device (see Examples).

What is the lifting distance of the storage magazine using the lifting device?

Detected by optical sensor etc. There are two types of optical sensors: a transmission type and a reflection type. When using a transmission type optical sensor, it is desirable to provide a long hole for detecting the elevation level in the back plate of the storage section (see Examples).

In this example, in order to smoothly align and store the electronic component mounting boards in the storage part, it is desirable to provide a vibration mechanism in the storage part (see the second embodiment). In addition, it is desirable to provide a mechanism for air blowing in the storage section (3rd section).
(See Examples).

[Function] In the present invention, when electronic component mounting boards are stacked in the storage section, the electronic component mounting boards tilt and slide toward the back plate along the bottom plate. Then, two right-angled sides of the electronic component mounting board come into contact with the back plate. As a result, a large number of electronic component mounting boards stacked in the storage section are naturally aligned.

Further, since the electronic component mounting substrate is aligned by the two right-angled sides of the electronic component mounting substrate in this manner, the electronic component mounting substrate is aligned and stored in the storage portion regardless of its size. Therefore, there is no need for setup time for matching the storage magazine to the size of the electronic component mounting board. Furthermore, it is not necessary to have precision in positioning the board for mounting electronic components into the storage section.

[Effects] Therefore, according to the present invention, it is possible to provide a storage magazine for electronic component mounting boards that has a simple structure and excellent workability.

〔Example〕

First Embodiment A storage magazine for electronic component mounting boards according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The storage magazine of this example is as shown in FIG.

It consists of a pedestal 1 and a storage section 2 provided on the pedestal 1. The storage section 2 consists of two back plates 21.22 arranged at right angles and a bottom plate 23 arranged at right angles to the lower parts of the two back plates 21.22. The storage section 2 is fixed to the base 1 while tilting backward.

In addition, the bottom plate 23 includes a housing board 8 for mounting electronic components.
A notch 230 is provided for taking out the.

The pedestal 1 is as shown in FIGS. 1 to 4.

It consists of a base plate 11 formed into a substantially rectangular plate shape and leg plates 12 erected on the cough base plate 11. The cough table plate 11 has a clamp groove 1.
form 10. A clamp 3 attached to the lifting device is engaged with the clamp groove 11O.

The lifting device is capable of positioning the storage magazine at an accurate height using a ball screw. The elevating device is connected to a controller (shown in the figure) which will be described later. Further, the lifting device is interposed between the continuity testing process and the packaging process.

As shown in FIGS. 2 and 3, the back plates 21 and 22 of the storage section 2 are fixed to the leg plates 12, respectively, by tilting backward at an angle θ. In this example, θ=10
It is set at once.

Further, a long hole 220 for detecting the elevation level of the storage magazine is formed in the back plate 22 so as to extend in the vertical direction. At the front and rear of the back plate 22, with the elongated hole 220 in between,
A transmission type optical sensor 4 is provided. The optical sensor 4 includes a light emitter 41 and a light receiver 42.

The optical sensor 4 is connected to a controller. A control program for the lifting device is input to the controller. The controller receives the output signal of the optical sensor 4 and uses the suction pad 5 attached to the transfer device to adjust the head height S when the electronic component mounting board 8 is placed into the storage section 2.
is always kept at a constant value (for example, 20 m).

The bottom plate 23 is arranged at right angles to the back plate 21,22. Therefore, the bottom plate 23 is also inclined rearward (at an angle of 10 degrees with respect to the horizontal direction) like the back plates 21 and 22.

As shown in FIG. 1, the bottom plate 23 is provided with a notch 230 extending diagonally from its corner. The notch 2
Reference numeral 30 denotes an opening portion into which a finger (illustrated path) of the handling device is inserted.

Since the storage magazine of this example is configured as described above, it exhibits a ninth-order effect.

That is, the electronic component mounting board 8 that has gone through the cleaning process and continuity testing process in the previous process is placed on the suction pad 5 (
(Fig. 2), the sheets are picked up one by one. The number of times of suction at this time is counted by the controller. When the transfer device picks up the sub-component mounting board 8, the second and third
As shown in the figure, the suction pad 5 is moved to the upper part of the storage section 2 of the storage magazine. Then, the suction state by the suction band 5 is released, and the electronic component mounting board 8 is dropped into the storage magazine.

On the other hand, in the storage magazine, the child component mounting board 8
The height is adjusted in advance using a lifting device so that the head difference S is a constant value.

Therefore, the electronic component mounting board 8 that has left the suction pad 5 falls with a constant height S. The electronic component mounting boards 8 that have been lowered are stacked in the storage section 2.

At this time, the electronic component mounting board 8 is mounted on the back plate 21, 22.
While sliding in the direction, its two sides abut against the back plate 21, 22. Therefore, the electronic component mounting board 8 is naturally aligned within the storage section 2. Also.

Since the electronic component mounting board 8 is naturally aligned in this way,
There is no need for positioning accuracy when inserting the electronic component mounting board 8 into the storage section 2.

Furthermore, by stacking the electronic component mounting substrates 8 in the storage section 2, the optical sensor 4 is in a state of being shielded from light by the electronic component mounting substrates 8. As a result, the optical sensor 4
detects that the electronic component mounting boards 8 are stacked and outputs a signal to the controller.

Therefore, the controller receives the above signal and outputs a control signal to the lifting device. The lifting device lowers the clamp 3 in response to the control signal. This causes the entire storage magazine to descend.

Then, when the optical sensor 4 receives light again and sends its output signal to the controller, the controller outputs a control signal to the lifting device to stop the lowering of the clamp 3. As a result, the head difference S from the suction pad 5 to the electronic component mounting board 8 always remains at a constant value.

A certain number of electronic component mounting boards 8 are placed in the storage section 2.
When the electronic component mounting boards 8 were stacked, the controller was counting the number of electronic component mounting boards 8.

Sends a control signal to the handling device.

Therefore, the handling device has a notch 23 in the finger.
Electronic component mounting board 8 stacked in one layer by being inserted into 0
Grip it from above and below. Then, the handling device moves the fingers to the next packing step while holding the electronic component mounting board 8.

Next, a case will be described in which electronic component mounting boards of different sizes are handled. In this case as well, the storage magazine described above is used as is. Since the two sides of the electronic component mounting board are positioned by the two back plates 21 and 22, the electronic component mounting board is aligned and stored in the storage section 2 regardless of the size of the electronic component mounting board. Therefore, there is no need for setup such as width adjustment of the seven storage sections 2 as in the prior art, and no setup time is required.

As described above, according to the two-piece example, the two-way work efficiency is greatly improved in the work of storing the electronic component mounting board in the storage magazine.

Second Embodiment For the storage magazine for the electronic component mounting board of this example, the fifth
This will be explained using figures. The storage magazine of this example is provided with a vibrator 6 for applying vibration to an electronic component mounting board 8.

That is, the pie break 6 is arranged on the back surface of the pedestal 1. The pipe rake 6 is connected to a controller and operates only when the electronic component mounting board 8 is inserted.

The rest is the same as the first embodiment.

Since the storage magazine of this example is configured as described above, when the electronic component mounting board 8 is inserted into the storage section 2, the vibrator 6 vibrates the entire storage magazine.

The vibrations are transmitted to the electronic component mounting board 8 in the storage section 2 via the back plate 21, 22 and the bottom plate 23. Therefore,
The electronic component mounting boards 8 stacked in nine stages in the storage section 2 are aligned with higher precision.

Furthermore, the same effects as in the first embodiment can be obtained.

Third Embodiment For the storage magazine for the electronic component mounting board of this example, the sixth
This will be explained using figures. The storage magazine of this example is provided with an air injection nozzle 7 for blowing air to the position where the electronic component mounting board 8 falls.

That is, in the two examples, the back plates 21 and 22 of the storage magazine
An air injection nozzle 7 is disposed at a drop position R of the electronic component mounting board 8 so as to face the electronic component mounting board 8. The air injection nozzle 7 is
Connect to an air compressor (path shown) via air tube 7I.

Further, a large number of through holes 70 are bored in the back plate 21, 22 of the storage magazine.

The rest is the same as the first embodiment.

The storage magazine of this example is configured as described above, so that when air is blown from the air injection nozzle 7 toward the back plate 2122, the air passes through the through hole 70 to the rear of the back plate 21, 22. There is a gap. Moreover, at this time, an air layer is formed at the drop position R of the child component mounting board 8.

Therefore, when the electronic component mounting board 8 is put into the storage section 2, the air layer acts as a cushion, and the electronic component mounting board 8 falls gently and slides smoothly on the air layer.

It abuts against the back plate 21,22.

Therefore, according to this example, the alignment of the electronic component mounting substrates 8 stacked in two stages can be improved.

Also, by blowing air, the electronic component mounting board 8
Dust attached to the surface of the can be removed. Therefore, the surface of the electronic component mounting board 8 is not scratched.

Further, the same effects as in the first embodiment can be obtained.
