Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a hoop material masking device. More specifically, in a device for masking the hoop material using tape to conceal the untreated part, as a pre-process when plating the hoop material, which is a strip-shaped thin plate, with a hoop material, It is intended to provide a masking device for hoop material that does not impair the quality of the material, can reduce the cost related to the tape, and has high accuracy.

[0002]

2. Description of the Related Art A conventional hoop material masking device is, for example, a device used in the case of strip plating for linearly plating a metal hoop material used for manufacturing electronic parts. As shown in FIG. 7 (a), a film-shaped tape 111 made of a material such as polypropylene and having an adhesive applied to the surface thereof is attached to a preheated hoop material 1
01, and then pressure-bonded to the hoop material 101 by a pressure-bonding roller (not shown).

Then, as shown in FIG. 7 (b), each slit S1 to S4 is made in the tape 111 by a blade (blade) of a slitter for making a cut in the tape 111, and then, in FIG. 7 (c). As shown, the tapes 112-1 and 112-2 at the portions to be plated are peeled off (conventional example 1). Note that, in FIG. 7, the thickness of the hoop material 101 and the tape 111 is exaggerated for convenience of description.

However, according to the conventional example 1, since the cuts S1 to S4 are made in the tape 111 pressed onto the hoop material 101 by the blade, the surface portion of the hoop material 101 may be damaged.

Therefore, in another conventional example, before crimping the tape to the hoop material, the tape is cut by a blade in advance, and then the necessary tape among the narrow tapes formed into several strips is used as the hoop material. Crimping is performed (conventional example 2).

[0006]

However, according to the conventional example 1 described with reference to FIG. 7, as described above, since the cuts S1 to S4 are made by the blade in the tape 111 pressed onto the hoop material 101, There is a problem to be solved that the surface portion of the hoop material 101 may be scratched, and as a result, the quality of the hoop material 101 is impaired.

Further, the tapes 112-1 and 112-2 that have covered the portions to be plated are peeled off as unnecessary and discarded. However, the masking tape 111
Are generally expensive. Therefore, according to the conventional example 1, the yield as the material of the tape 111 is low,
There is also an unsolved problem that the cost of the tape 111 becomes high.

Further, according to the conventional example 1, when the tapes 112-1, 112-2 to be peeled off as unnecessary ones have a narrow width, the tapes 112-1, 112- are peeled off at the time of peeling.
2 may be cut. In that case, there has been a problem to be solved that the operation of the apparatus must be stopped and the workability as the masking apparatus is deteriorated.

In addition, when it is necessary to apply extremely fine strip plating of, for example, about 25 to 35 μm to the hoop material 101, the tape 111 should be cut so that the width becomes 25 to 35 μm. Conventional example 1 has a problem that it cannot be peeled off.

On the other hand, according to the second conventional example, although the hoop material is not scratched, several tapes cut into pieces before the pressure bonding are pressure bonded to the hoop material without any guide. Therefore, there is also a problem to be solved in that the accuracy of about 100 μm cannot be ensured.

Also in this conventional example 2, since the unnecessary portion of the cut tape is discarded as in the conventional example 1, the yield of the tape is low and the cost of the tape is high. Since the unnecessary part is wound by the winding device, the tape is pulled due to this and the accuracy is reduced, and it is peeled as unnecessary.If the width of the tape is narrow, peel it off. There is an unsolved problem that the tape may sometimes break and cannot be used for extremely fine strip plating.

[0012]

The present invention has been made in view of the above problems. Therefore, in the present invention, in a hoop material masking device in which a masking tape coated with an adhesive is pressure-bonded to a hoop material by a pressure roller, a slitter having a blade that divides the supplied tape into several rows is provided. , At least one tape guide that guides the feeding of several tapes separated by a slitter is arranged in the vicinity of the pressure roller, and the several tapes supplied through this tape guide are hooped by the pressure roller. The material was crimped and moved to the winding side.

BEST MODE FOR CARRYING OUT THE INVENTION The configuration of a hoop material masking device according to one embodiment of the present invention will be described with reference to FIG. Here, in FIG. 1, a support tool for supporting each part of the apparatus and an apparatus main body to which each support tool is attached are not shown for simplicity of description.

In FIG. 1, reference numeral 51 designates a freely rotating spindle for supporting a reel wound with a masking tape (not shown in the figure), 61a and 6a.
1b is a guide roller having flanges at both ends for guiding the feeding of the supplied tape, and 1b.
As shown in FIG. 6A, 1 is a slitter for cutting the tape 111 into several tapes having a narrow width. The structure of the slitter 11 is shown in FIG. Here, FIG. 2 is a perspective view showing the configuration of the slitter 11.

In FIG. 2, the slitter 11 is formed in a semi-cylindrical shape, and four blades 12-1 to 12-4 for cutting the tape are erected at predetermined intervals on the peripheral surface portion thereof. Has been done.

The slitter 11 constructed as described above is carried on a carrier 13, and the carrier 13 is supported by support shafts 16a and 16b, both ends of which are supported by supporters 15a and 15b, respectively. It is supported and can swing in the length direction of the tape. The one support shaft 16b has a rotating plate 17 that is rotated by the drive of the motor 18.
It is connected to. Therefore, when the motor 18 is driven, the slitter 11 swings, and in the present embodiment, it swings by plus or minus 15 degrees.

As described above, if the slitter 11 is swung, the number of the blades 12-1 to 12-4 that come into contact with the tape is not limited to one.
The tape comes into contact with the blades 1 to 4 as a whole, and good sharpness of the blades 12-1 to 12-4 can be maintained for a long time. However, each blade 12-1
It is not necessary to swing the slitter 11 unless the durability of ~ -4 is taken into consideration.

When the tape is continuously cut by the blades 12-1 to 12-4 without swinging the slitter 11, the adhesive applied to the tape is applied to the blades 12-1 to 12-4.
Will be attached and deposited on the part of the tape that contacts the tape. However, in such a state, the cutting of the blades 12-1 to 12-4 becomes worse, but if the slitter 11 is swung, the adhesion of the adhesive to the blades 12-1 to 4 is reduced. The effect is obtained.

The respective constituent elements including the swinging slitter 11 are mounted and disposed on a movable plate 14 which is movable, and the movable plate 1 is constructed by using a micrometer head 20.
By moving 4 the position of the slitter 11 can be finely adjusted.

That is, a slider (not shown) attached to the bottom surface of the movable plate 14 is fitted to the guide rail, and the movable plate 14 is compressed by the coil spring acting on the micrometer head. 20
Is biased to the side. Therefore, by rotating the rotating part of the micrometer head 20, the movable plate 1
4 can be moved in one axis direction.

In FIG. 1, 21a and 21b are tape guides for guiding the feeding of narrow tapes divided into several pieces by the slitter 11, and one tape guide 21b is a tape guide. It is arranged in the vicinity of a freely rotating pressure-bonding roller 31 whose peripheral surface is covered with rubber for pressure-bonding to the hoop material. The structure of these tape guides 21a, 21b is shown in FIG. Here, FIG. 3 shows each tape guide 21a,
21b is a perspective view showing the configuration of 21b, for the sake of simplicity of explanation,
Although only the structure of the one tape guide 21a is illustrated, the structure of the other tape guide 21b is also the same.

In FIG. 3, the tape guide 21a is
Each partition plate 23-1 for partitioning and guiding the tape divided into several lines on the base 22 formed in a semi-cylindrical shape
~ -4 are provided. In this tape guide 21a, each tape divided into three sections is divided into each partition plate 23-
It will be sent through between 1 and -4. Note that FIG.
Although not shown in the figure, each tape guide 21a, 21
Similar to the slitter 11, b is movable in the uniaxial direction, and its position can be finely adjusted.

In FIG. 1, reference numerals 71a to 71g designate freely rotating rollers 41a and 41, respectively, for feeding a hoop material (not shown in the figure).
Reference numeral b is a hoop guide for guiding the feeding of the hoop material. These hoop guides 41a, 4
1b is a view taken along the line AA of FIG.
Is shown in Although FIG. 4 shows only the structure of one tape guide 41a, the structure of the other tape guide 41b is also the same.

In FIG. 4, the hoop guide 41a is
It is composed of plate-shaped guide members 42a and 42b provided upright on the support plates 43a and 43b, respectively, and the hoop material is fed through between the guide members 42a and 42b.

The supporting plates 43a and 43b are respectively attached to the carrying plates 44.
It is carried by a and 44b. Then, each carrying plate 44
Sliders 45a and 45b fitted to the guide rail 46 are attached to the bottom surfaces of the a and 44b, respectively. Therefore, each guide member 42a, 42
b is movable in the uniaxial direction, and the distance between the two can be adjusted. This is for coping with this, because in the case of bag-cladding in which the tape is crimped so that the tape protrudes from both ends of the hoop material, the accuracy decreases if the protruding portion is turned up.

That is, the rods 47a and 47b attached to the bottoms of the supporting plates 44a and 44b respectively have coil springs 48a,
48b are respectively connected. Therefore, by rotating the rotating parts of the respective micrometer heads 49a and 49b (support members are not shown), the respective guide members 42 are rotated.
The interval between a and 42b can be finely adjusted as appropriate.

The hoop material to be sent is the support plate 43.
The roller 71d is mounted at a position where the peripheral edge of the roller 71d is slightly higher than the upper surface of each support plate 43a, 43b in order to prevent the roller from contacting the a and 43b and being damaged. This point is that each of the other rollers 71a-c, 7
The same applies to 1e to g.

In FIG. 1, reference numerals 32a and 32b denote winding sides of the hoop material to which the tape is pressure-bonded (left side in the drawing).
It is a pair of rollers having the same structure as the pressure bonding roller 31 for moving and sending to. Here, one roller 32a
Are driven by a driving device (not shown). On the other hand, the other roller 32b is free to rotate and the position in the vertical direction can be adjusted, and the distance between the other roller 32a and the roller 32a can be adjusted freely.

Reference numeral 81 denotes an inhaler for inhaling the debris by driving the blower when the tape is cut by the slitter 11 and both ends of the tape are formed into unnecessary debris.

Reference numeral 72 denotes the roller 7 when the hoop material is fed to the reel for winding the hoop material to which the tape is pressure-bonded.
In order to move the hoop material horizontally up to position 2,
The pressure roller 31 has the same structure as the pressure roller 31.

Next, the operation state when the present apparatus configured as described above is operated is shown in FIGS.
This will be described with reference to FIG. Here, in FIG. 5, for convenience of explanation,
Illustration of the hoop guides 41a and 41b (FIG. 1) is omitted.

In FIG. 5, first, prior to operating the present apparatus, the hoop material 101 wound on the reel is unwound, and the hoop material 1 is fed through a heater (not shown).
01 is heated to a predetermined temperature, and is then passed between the pressure bonding roller 31 and the roller 71f to feed the feed rollers 32a, 32f.
The leading portion of the hoop material 101 is extended to a position near b.

On the other hand, the tape 111 wound on the reel is unwound, and the slitter 11 cuts the tape 111 into several pieces as shown in FIG. The cut tape 111 passes through the guide roller 61b, and then the tape shown in FIG.
As shown in (b), each tape guide 21a, 21b
Of the feed rollers 3 through the partition plates 23-1 to 23-4 and between the pressure bonding roller 31 and the roller 71f.
It is extended to a position near 2a and 32b.

Then, the tape 11 is divided into several pieces.
The head portion of No. 1 is fixed to the hoop material 101 with an adhesive tape or the like by locating the interval between the tapes 111, and then the hoop material 101 is inserted between the feed rollers 32a and 32b.

Then, when the feed roller 32a is driven and the hoop material 101 is fed, a portion having a certain length from the head portion of the hoop material 101 (the tape guide 2 before starting).
The portion up to 1b) does not have the desired accuracy and becomes a defective portion. After that, as shown in FIG. 6A, several tapes 1 cut by the slitter 11 are used.
11 is a tape guide 2 as shown in FIG.
According to the setting made by 1b, the hoop material 101 is pressure-bonded in a desired pattern as shown in FIG. 6 (c).

According to an experiment conducted by the inventor of the present application, according to the present invention, one tape guide 21b is attached to the pressure roller 3
Since the tape 111 is arranged in the vicinity of 1, the accuracy of the crimping position of the tape 111 is about ± 35 μm, which is a good result.

The width of the tape 111 is equal to the width of the hoop material 10.
When the tape 111 is not required to have both ends as shown in FIG.
The unnecessary portion is inhaled by the inhaler 81 (FIG. 1) and collected. This is because the tape 1 is conventionally wound by an unwinding device on an unnecessary portion of the tape 111.
This is in consideration of the fact that 11 is pulled and the accuracy is lowered due to this.

In the above description, the case where the tape 111 is pressure-bonded to the hoop material 101 which has been heated to a predetermined temperature has been described. However, the hoop material 101 is heated only by the pressing force of the pressure-bonding roller 31 without heating the hoop material 101.
The present invention can be applied even when the tape 111 is pressure-bonded to the.

Further, the blade 1 of the slitter 11 (FIG. 1)
2-1 to -4 (FIG. 2) and each tape guide 21a,
The case where the number of the partition plates 23-1 to -4 (FIG. 3) of each of 21b (FIG. 1) is four has been described as an example. But,
The present invention is not limited to this, and the present invention can be applied to other numbers. That is, the number can be set as needed.

Further, each tape guide 21a, 21b
Can be appropriately used with a desired spacing between the partition plates 23-1 to -4. In that case, each partition plate 23-1
If the tape guides 21a and 21b are configured so that the distances can be adjusted freely by changing the positions of ~ -4, it is not necessary to replace the tape guides 21a and 21b. Each tape guide 21a, 2
1b can be used as it is, which is effective in improving workability.

In addition, each of the partition plates 23-1 to 23-4 is used not as one plate member but as two thinner plate members are superposed on each other, and the distance between the two plate members is finely adjusted. If so configured, it is possible to finely adjust the width of the portion to be plated.

On the other hand, if the thickness of each of the partition plates 23-1 to 23-4 in each of the tape guides 21a and 21b is made minute, when the strip plating with a width of about 25 μm is applied to the hoop material. Can also respond.

Further, the support shaft 5 which is a component of the tape
1 (FIG. 1), the guide rollers 61a and 61b, the slitter 11, the tape guides 21a and 21b, and the inhaler 81 are arranged at symmetrical positions with respect to the rollers 71a to 71f, respectively. The present invention can also be applied to the case of double-sided adhesion in which tapes are pressure-bonded to both sides of the material.

In addition to the case where the hoop material is plated, for example, when the hoop material is coated with an insulating material, or when the hoop material is a punched material,
It will be apparent from the above description that the present invention can be applied.

[0045]

As is apparent from the above description, according to the present invention, the tape is cut into several strips by the slitter before the tape is pressure-bonded to the hoop material, so that the surface of the hoop material is scratched. There is no such thing. That is, the quality of the hoop material is not impaired.

Further, since all of the tapes of several lines previously cut by the slitter are used for pressure bonding to the hoop material, there is almost no portion to be discarded as an unnecessary portion.
Therefore, not only the yield as a material of a generally expensive tape is good, but also a tape having a narrower width can be used. As a result, the narrower the width of the masking tape, the lower the cost, and the cost of the tape can be significantly reduced.

Moreover, even if the width of the portion to be plated is narrow, it is not necessary to peel the tape having a narrow width as an unnecessary portion unlike the conventional example, and therefore the tape to be peeled is cut off. There is no need to stop the operation of the device, and good workability as a masking device can be obtained.

Further, since the tape guide for guiding the feeding of the tape divided into several lines is arranged in the vicinity of the pressure bonding roller, not only high accuracy can be obtained as compared with the conventional example, but also the hoop material can be obtained. It is not possible with the conventional example because there is no need to make a cut in the pressure-bonded tape and peel it off.
Very fine strip plating with a width of about 5 μm is possible according to the present invention. Therefore, the effect provided by the present invention is extremely large.
