Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printed circuit board dividing apparatus for dividing a printed circuit board.
[0002]
[Prior art]
Conventionally, in a multi-sided printed board (hereinafter referred to as “multi-sided board”), long holes (so-called perforations) are intermittently provided at the boundary portion of each printed board (hereinafter referred to as “individual board”). It is often used to divide a multi-sided substrate by cutting a connecting portion located between the eye and the perforation.
[0003]
Here, for example, in Patent Document 1, a lifting table is provided above the multi-sided substrate, and a plurality of cutters corresponding to the connecting portions are disposed on the back surface of the lifting table.
[0004]
On the other hand, a substrate receiver is provided on the back surface of the multi-sided substrate so as to correspond to the cutter, and when the cutter is pressed against the multi-sided substrate, stress is concentrated on the connecting portion to facilitate cutting the connecting portion. However, this requires a lifting table and a substrate holder that match the shape of the multi-sided substrate, and costs increase.
[0005]
For this reason, in Patent Document 2, as shown in FIG. 6, the multi-sided substrate 102 is horizontally moved using the actuator 100. Accordingly, it becomes possible to cut the connecting portion 102B located between the perforation 102A and the perforation 102A formed on the multi-surface substrate 102 shown in FIG. Costs can be reduced because there is no need to make individual substrate holders.

[Problems to be solved by the invention]
However, in the case of a multi-sided substrate, at the boundary portion between adjacent individual substrates (hereinafter referred to as “the center side of the multi-sided substrate”), unless the cutting portion is cut with a blade portion having an outer diameter substantially the same as the width of the perforation, A convex portion is formed on the end face of the divided individual substrate, and when the individual substrate is incorporated into a product, the convex portion may become an obstacle and cannot be incorporated into the product.
[0008]
On the other hand, since the outer edge side of the multi-sided substrate becomes a discarded substrate, the end surface of the multi-sided substrate can be made a flat surface without unevenness by cutting the connecting portion along the inside of the perforation.
[0009]
Here, when cutting a multi-sided substrate, the cutting time is substantially proportional to the cutting area, so that the working area is better when the cutting area is smaller. For this reason, in the connection part of the outer edge side of a multi-sided board | substrate, while cutting along the inner side of a perforation, it is better to narrow the width | variety for cut | disconnecting.
[0010]
However, on the central side of the multi-sided substrate, it is necessary to prevent the projections from being formed on the end surfaces of the divided individual substrates, and it takes time to replace the blades. For this reason, the blade portion is selected in accordance with the width of the perforation at the boundary portion, and the multi-sided substrate is cut without distinguishing the blade portion between the outer edge side connecting portion and the central side connecting portion.
[0011]
Therefore, the connecting portion on the outer edge side of the multi-sided substrate must be cut with a width substantially the same as the width of the perforation, although it may be cut with a width narrower than the width of the perforation. Not only will it take a long time to cut, but it will also shorten the life of the blade.
[0012]
In consideration of the above-described facts, the present invention has an object to obtain a printed circuit board dividing device that can be cut without changing the substrate holder depending on the shape of the printed circuit board, reduces the cutting time, and extends the life of the blade portion. And
[0013]
[Means for Solving the Problems]
The invention according to claim 1 is a cutting member capable of cutting a printed circuit board, a mounting table disposed below the cutting member and formed with a blade portion receiving portion into which a blade portion of the cutting member enters, and the print And a moving means for horizontally moving the substrate on the mounting table, wherein the blade portion has a stepped shape of a small diameter blade and a large diameter blade having different outer diameters, and the blade portion The receiving portion includes a small-diameter blade entry portion into which the small-diameter blade enters and a large-diameter blade entry portion into which the large-diameter blade enters, and corresponds to the small-diameter blade or the large-diameter blade. A switching means for switching to the diameter blade entry portion is provided.
[0014]
In the first aspect of the invention, the blade portion of the cutting member capable of cutting the printed circuit board has a stepped shape of a small diameter blade and a large diameter blade having different outer diameters. For example, in the case of a multi-sided printed circuit board (multi-sided board), a long hole part (perforation) is usually formed intermittently at the boundary part of each printed circuit board (individual board), and between the long hole part and the long hole part The connecting portion located at is cut into individual substrates.
[0015]
Here, in the boundary part of the adjacent individual substrates of the multi-sided substrate (the center side of the multi-sided substrate), unless the connecting part is cut with the blade part having the substantially same width as the perforation, the end face of the divided individual board In this case, a convex portion is formed, and there is a risk that the convex portion becomes an obstacle when the individual substrate is incorporated into the product, and cannot be incorporated into the product.
[0016]
On the other hand, since the connecting portion on the outer edge side of the multi-sided substrate becomes a discarded substrate, the end surface of the multi-sided substrate can be made a flat surface without unevenness by cutting the connecting portion along the inside of the perforation.
[0017]
By the way, when cutting a multi-sided substrate, the cutting time is substantially proportional to the cutting area, and therefore the working efficiency is better when the cutting area is smaller. For this reason, in the connection part of the outer edge side of a multi-surface board | substrate, while cutting along the inner side of a perforation, a multi-surface board | substrate is cut | disconnected using a small diameter blade as a blade part of a cutting member. On the other hand, since it is necessary to cut with a width substantially the same as the width of the perforation at the connecting portion on the center side of the multi-sided substrate, a large-diameter blade is used as the blade portion.
[0018]
That is, the connecting portion on the outer edge side of the multi-sided substrate is cut with a small diameter blade, and the connecting portion on the center side of the multi-sided substrate is cut with a large diameter blade. Thereby, the cutting time can be reduced as compared with the case where the outer edge side connecting portion of the multi-sided substrate and the central side connecting portion of the multi-sided substrate are cut with a large-diameter blade. Moreover, the lifetime of the blade part of a cutting member can be lengthened by forming a large diameter blade and a small diameter blade in one cutting member, and switching a large diameter blade and a small diameter blade according to a cutting location.
[0019]
On the other hand, a mounting table is disposed below the cutting member, and a blade portion receiving portion into which the blade portion of the cutting member enters is provided. The blade receiving portion is constituted by a small-diameter blade entry portion into which a small-diameter blade enters and a large-diameter blade entry portion into which a large-diameter blade enters. Then, the switching means switches to the small diameter blade entry portion or the large diameter blade entry portion of the mounting table corresponding to the small diameter blade or the large diameter blade of the cutting member.
[0020]
Here, moving means for horizontally moving the multi-sided substrate on the mounting table is provided. As a result, the cutting position of the multi-sided substrate can be moved on the mounting table, so that it is not necessary to provide a mounting table individually according to the shape of the multi-sided substrate, and a plurality of multi-sided substrates having different shapes on one mounting table. Can be cut. For this reason, cost reduction can be aimed at.
[0021]
Further, the mounting table is provided with a small diameter blade entry portion or a large diameter blade entry portion corresponding to the small diameter blade or the large diameter blade, and is switched to the small diameter blade entry portion or the large diameter blade entry portion by the switching means. That is, the width of the blade receiving portion is changed in accordance with the width to be cut. Thereby, stress can be concentrated on the connection part located between perforations, and a multi-sided board can be cut efficiently.
[0022]
The invention described in claim 2 is characterized in that the switching means is a rotating means for rotating the mounting table by a predetermined angle. In the second aspect of the invention, the mounting table is rotated by a predetermined angle by the rotating means, and is switched to the small diameter blade entry portion or the large diameter blade entry portion. Thus, since the blade portion receiving portion is switched by rotating the mounting table, the mechanism is simple and the necessary space can be minimized.
[0023]
According to a third aspect of the present invention, a dust collector is provided below the cutting member to suck the chips generated when the printed circuit board is cut through the small-diameter blade entry portion or the large-diameter blade entry portion. It is characterized by that.
[0024]
In a third aspect of the present invention, a dust collecting device is provided below the cutting member to suck the chips generated when cutting the multi-sided substrate through the small-diameter blade entry portion or the large-diameter blade entry portion. Thus, the suction pipe can be made to the minimum size by sucking the chips generated when cutting the multi-sided substrate through the small diameter blade entry portion or the large diameter blade entry portion, and the dust collector Can be made compact.
[0025]

[0035]
The motor 36 is capable of forward and reverse rotation. When the motor 36 is operated, the ball screw 34 rotates, and the clamp member 30 slides in the direction of arrow B along the ball screw 34 via the nut portion 32.
[0036]
Here, the contact portion 30 </ b> A and the slider 28 are smooth surfaces having a small surface friction coefficient, and the contact portion 30 </ b> A slides smoothly on the slider 28. Further, the contact portion 30A is provided with a long hole portion 38 along the ball screw 34, and the slider 28 is provided with a pin 28A that engages with the long hole portion 38.

If the connecting portion 58 of 22 is not cut, a convex portion 55 (see FIG. 5A) will be formed on the end face of the divided individual substrate 54, and the convex portion 55 is projected when the individual substrate 54 is incorporated into the product. There is a possibility that the part 55 may be in the way and cannot be incorporated into the product.
[0049]
On the other hand, since the connecting portion 58 on the outer edge side of the multi-sided substrate 22 becomes the discarded substrate 57, the connecting portion 58 is cut along the inner side of the perforation 56 as shown in FIG. The end surface of the substrate 22 can be a flat surface without unevenness.
[0050]
By the way, when cutting the connecting portion 58, the cutting time is substantially proportional to the cutting area, so that the working area is better when the cutting area is smaller. For this reason, the connecting portion 58 on the outer edge side of the multi-sided substrate 22 may be cut along the perforation 56, and the multi-sided substrate 22 is cut using the small-diameter blade 20 </ b> A as the blade portion 20. On the other hand, in the connecting portion 58 on the center side of the multi-sided substrate 22, it is necessary to cut with a width substantially the same as the width of the perforation 56.
[0051]
That is, the connecting portion 58 on the outer edge side of the multi-sided substrate 22 is cut with the small diameter blade 20A, and the connecting portion 58 on the center side of the multi-sided substrate 22 is cut with the large-diameter blade 20B. Thereby, the cutting time can be reduced as compared with the case where the outer peripheral side connecting portion 58 of the multi-sided substrate 22 and the central side connecting portion 58 of the multi-sided substrate 22 are cut with the large-diameter blade 20B.
[0052]
Moreover, the long diameter blade 20B and the small diameter blade 20A are formed in one router bit 18, and the life of the blade portion 20 of the router bit 18 is extended by switching the large diameter blade 20B and the small diameter blade 20A according to the cutting location. be able to.

The blade receiving portion 24 is configured by a small-diameter blade entry hole 24A through which a small-diameter blade enters and a large-diameter blade entry hole 24B through which a large-diameter blade enters.
[0054]
Then, corresponding to the small diameter blade 20A or the large diameter blade 20B of the router bit 18, the stepping motor 12 is operated to switch to the small diameter blade entry hole 24A or the large diameter blade entry hole 24B of the mounting table 16. Yes.
[0055]
Here, the cutting position of the multi-sided substrate 22 is moved on the mounting table 16 by horizontally moving the multi-sided substrate 22 on the mounting table 16 by the motors 36 and 48, the ball screws 34 and 50, the nut portions 32 and 52, and the like. Therefore, the motors 36 and 48 are operated to position the cut portion of the multi-sided substrate 22.
[0056]
When the cutting portion is the connecting portion 58 on the outer edge side of the multi-sided substrate 22, the stepping motor 12 is operated so that the small diameter blade entry hole 24 </ b> A of the blade portion receiving portion 24 of the mounting table 16 faces the router bit 18.
[0057]
Then, the small-diameter blade 20A of the router bit 18 is disposed inside the perforation 56 by the lifting device, the router bit 18 is operated, and the multi-sided substrate 22 is slid in the direction opposite to the cutting direction by the motor 36 or the motor 48. The connecting portion 58 of the substrate 22 is cut.
[0058]
On the other hand, when the cut portion is the connecting portion 58 on the center side of the multi-sided substrate 22, the stepping motor 12 is operated so that the large-diameter blade entry hole 24 </ b> B of the blade receiving portion 24 of the mounting table 16 faces the router bit 18. To do.
[0059]
Then, the large-diameter blade 20B of the router bit 18 is arranged in the perforation 56 by the lifting device, the router bit 18 is operated, and the multi-sided substrate 22 is slid in the direction opposite to the cutting direction by the motor 36 or the motor 48. The connecting portion 58 of the substrate 22 is cut.
[0060]
As described above, the multi-surface substrate 22 is horizontally moved on the mounting table 16, and the cutting position of the multi-surface substrate 22 is moved on the mounting table 16, so that the mounting table 16 is individually provided according to the shape of the multi-surface substrate 22. There is no need, and a single mounting table 16 can cut a plurality of multi-sided substrates 22 having different shapes. For this reason, cost reduction can be aimed at.
[0061]
Also, here, the mounting table 16 is provided with a small diameter blade entry hole 24A or a large diameter blade entry hole 24B corresponding to the small diameter blade 20A or the large diameter blade 20B, and the mounting table 16 is rotated 90 degrees by the stepping motor 12. The small diameter blade entry hole 24A or the large diameter blade entry hole 24B is switched.
[0062]
That is, by changing the width of the blade portion receiving portion 24 according to the width to be cut, stress can be concentrated on the connecting portion 58 located between the perforations 56 and the multi-sided substrate 22 can be efficiently formed. Can be cut.
[0063]
Further, since the blade receiving portion 24 is switched by rotating the mounting table 16 by the stepping motor 12, the mechanism is simple and the necessary space can be minimized.
[0064]
Further, a dust collecting device 60 is provided below the mounting table 16, and the suction pipe 62 of the dust collecting device 60 is substantially brought into contact with the back surface of the mounting table 16, so that chips generated when cutting the multi-sided substrate 22 are for small diameter blades. By suctioning through the entry hole 24A or the large-diameter blade entry hole 24B, the suction pipe can be minimized, and the dust collecting device 60 can be made compact.
[0065]
In this example, the motors 36 and 48, the ball screws 34 and 50, and the nut portions 32 and 52 are used as means for horizontally moving the multi-sided board 22. However, it is sufficient that the multi-sided board 22 can be horizontally moved. Therefore, the mechanism is not limited to this, and a mechanism using a pinion, a rack, or the like may be used.
[0066]
Further, although the mounting table 16 is provided with the small-diameter blade entry holes 24A or the large-diameter blade entry holes 24B alternately every 90 degrees, the present invention is not limited to this. For example, a plurality of blade portions having different sizes of the large diameter blade and the small diameter portion are used, and the blade portion of the router bit is exchanged according to the multi-sided substrate. In this case, since it is necessary to form the entrance holes having different sizes according to the size of the blade portion on the mounting table, the pitch of the entrance holes along the circumferential direction of the mounting table is narrowed.
