DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an electrophotographic copying machine,
The present invention relates to a film-shaped electrode used for arranging electrodes of an electrodeless lamp used in OA equipment such as an image scanner, a fax machine, and a digital PPC, a method of manufacturing the same, a manufacturing apparatus thereof, and an electrodeless lamp using the film-shaped electrode. is there.

[0002]

2. Description of the Related Art Conventionally, a cold cathode discharge lamp has been used as a light source for OA equipment. However, since the cold cathode discharge lamp has a low luminous efficiency and a low luminous speed, an electrodeless lamp in which these are improved has recently been awarded in OA equipment which requires high performance.

[0003] As shown in FIG.
Two rectangular aluminum electrodes 2 are disposed on the outer periphery of a cylindrical glass tube 1 so as to face each other, and a rare gas such as xenon is sealed in the hollow of the cylindrical glass tube 1. This electrodeless lamp applies an AC voltage (about 2.6 KV) to the strip-shaped aluminum electrode 2,
By passing a current between the opposing strip-shaped aluminum electrodes 2, a rare gas sealed in the cylindrical glass tube 1 is excited, and the phosphor emits light with the energy to be used as a light source. .

[0004] However, although the above electrodeless lamp has an excellent function as a light source, in the manufacturing process thereof, the strip-shaped aluminum electrode 2 is arranged on the outer peripheral surface of the cylindrical glass tube 1 by hand. And there is a problem that manufacturing efficiency is poor.

Therefore, the applicant of the present invention has proposed a technique as shown in FIG.
An electrode member 6 having a configuration in which a strip-shaped aluminum electrode 2 is provided on one surface of a polyethylene terephthalate film (hereinafter referred to as “PET film”) via a film-side acrylic pressure-sensitive adhesive layer 5 is devised. An adhesive layer 7 for attaching an electrode is provided on the exposed surface of the aluminum electrode 2, and a film-like electrode on which a separator 8 is attached by utilizing the adhesive strength of the acrylic adhesive layer 5 on the film side and the adhesive layer 7 for attaching an electrode. I got According to this, the electrode member 6 can be easily attached to the cylindrical glass tube 1 simply by peeling off the separator 8.

[0006]

However, when a lighting test is repeatedly performed on the electrodeless lamp in which the electrode member 6 is wound around the cylindrical glass tube 1 under a condition of high temperature and high humidity (60 ° C. × 90 RH%), Strip-shaped aluminum electrode 2
It has been found that there is a possibility that a hole will be formed in the PET film 4 near the edge of. That is, when the above-mentioned electrode member 6 is wound around the glass tube 1, as shown in FIG. 10, on the outer periphery of the glass tube 1, a convex portion caused by the thickness of the above-mentioned strip-shaped aluminum electrode 2 and the pressure-sensitive adhesive layer 7 is attached. It is formed. Therefore, a gap 9 is formed between the end face of the strip-shaped aluminum electrode 2 and the film-side acrylic pressure-sensitive adhesive layer 5, and the film-side acrylic pressure-sensitive adhesive layer 5 near the edge of the strip-shaped aluminum electrode 2 Relatively thin. Therefore, when an AC voltage is applied to such an electrode member 6 to turn on the electrodeless lamp, the phase of the voltage always changes, so that an electric shock is repeatedly applied to the edge of the strip-shaped aluminum electrode 2. Therefore, the film-side acrylic pressure-sensitive adhesive layer 5 is damaged, and the PET film 4 is eventually deteriorated. On the other hand, since the acrylic pressure-sensitive adhesive used for the film-side acrylic pressure-sensitive adhesive layer 5 has water absorbability, moisture stays in the film-side acrylic pressure-sensitive adhesive layer 5 under high humidity conditions. As a result, the polyethylene terephthalate molecular chain of the PET film 4 is hydrolyzed and cut. Therefore, there is a problem that a hole is formed in the PET film 4. When such holes are formed, insulation failure occurs and the reliability of the electrodeless lamp is impaired.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a film-like electrode which does not cause a hole in a PET film even when an electrodeless lamp is turned on, and a film-like electrode. It is an object of the present invention to provide a manufacturing method that can be performed, a manufacturing apparatus thereof, and an electrodeless lamp using the film-shaped electrode.

[0008]

In order to achieve the above object, the present invention provides a two-piece strip having a connection terminal at one end on one side of a PET film via a film-side adhesive layer. An electrode member is formed by juxtaposing aluminum electrodes, an adhesive layer for electrode attachment is formed on an exposed surface of the strip-shaped aluminum electrode, and the film-side adhesive layer and the adhesive layer for electrode attachment are used. The electrode member is a film-shaped electrode that is detachably attached to one surface of the separator, and the film-side pressure-sensitive adhesive layer is a film-shaped electrode formed of a material containing a silicone-based pressure-sensitive adhesive. This is the first gist. Further, on one surface of the PET film, a pair of strip-shaped aluminum electrodes each having a connection terminal at an end is arranged side by side via a film-side pressure-sensitive adhesive layer to constitute an electrode member. A pressure-sensitive adhesive layer for electrode attachment is formed on the exposed surface of the electrode, and a plurality of the electrode members are arranged in parallel using the film-side pressure-sensitive adhesive layer and the pressure-sensitive adhesive layer for electrode attachment. A second aspect is a film-like electrode which is detachably attached to one surface of the film-like electrode, wherein the film-side pressure-sensitive adhesive layer is formed of a material containing a silicone-based pressure-sensitive adhesive. Further, on one surface of the strip-shaped separator, a large number of strip-shaped aluminum electrodes are arranged in pairs, and the electrodes are arranged side by side in a state orthogonal to the longitudinal direction of the strip-shaped separator via an adhesive layer for electrode attachment. A step of preparing a film, a step of preparing a laminated film in which a film-side pressure-sensitive adhesive layer is formed on one surface of a strip-shaped PET film, and a film of the laminated film with the strip-shaped aluminum electrodes arranged on the electrode-equipped film. Bonding the two side surfaces together with the side pressure-sensitive adhesive layer forming surface, and forming a belt-shaped PET between one set of strip-shaped aluminum electrodes and another set of strip-shaped aluminum electrodes adjacent thereto in the integrated body. A slit is made in the film part or at least a part is cut out, and the above-mentioned strip-shaped aluminum electrodes are individually covered with the remaining PET film for each set. And a step of attaching a connection terminal to one end of the strip-shaped aluminum electrode, wherein the film-side pressure-sensitive adhesive layer contains a silicone-based pressure-sensitive adhesive. A third aspect of the present invention is a method of manufacturing a film-shaped electrode formed of a material. Then, a method for producing a film-shaped electrode including a step of preparing a film-shaped electrode having a plurality of electrode members and a step of cutting the strip-shaped separator of the film-shaped electrode into two pairs of strip-shaped aluminum electrodes is described. This is the gist of 4. A moving means for relatively moving a strip-shaped separator having an aluminum sheet adhered to one surface thereof, and a rotary cutter disposed in opposition to the aluminum sheet; A rotary cutter for half-cutting at predetermined intervals in a direction orthogonal to the direction,
An unnecessary portion between the electrode forming portion of the aluminum thin plate having undergone the half-cut and another electrode forming portion adjacent thereto is removed, and a plurality of strip-shaped aluminum electrodes are arranged on one surface of the strip-shaped separator in a state perpendicular to the longitudinal direction thereof. A means for providing a laminated film having a strip-shaped PET film on one surface and a film-side pressure-sensitive adhesive layer formed on a surface of the separator obtained by the rotary cutter, on which the strip-shaped aluminum electrodes are provided; A set of strip-shaped aluminum electrodes, and slit or cut out at least a part of the strip-shaped PET film between this set and another set adjacent thereto, and the above-mentioned strip-shaped aluminum electrodes are Means for individually covering with a residual PET film, and a connection terminal at one end of the strip-shaped aluminum electrode An apparatus for producing a film-like electrodes and means for mounting said film side adhesive layer, a method of film-like electrodes formed by forming a material containing a silicone-based adhesive and the fifth aspect. further,
On the outer peripheral surface of a transparent tubular body whose both ends are closed and a rare gas is sealed therein, a pair of strip-shaped aluminum electrodes having connection terminals in the film-shaped electrode are arranged in parallel. With the electrode member, with both connection terminals positioned at one end of the tubular body, the two strip-shaped aluminum electrodes are disposed inside, and the electrodeless lamp is adhered so as to face each other. This is the sixth gist.

In other words, in order to prevent holes from being formed in the PET film, the present inventors formed an electrically and chemically reinforced layer instead of the film-side acrylic pressure-sensitive adhesive layer. I remembered that it was good and repeated various studies on it. As a result, if the layer formed on the PET film side is a layer formed of a material containing a silicone-based pressure-sensitive adhesive, the properties peculiar to the silicone-based pressure-sensitive adhesive, that is, the electrical properties are excellent (volume resistivity and dielectric breakdown). High voltage) and chemically stable (excellent in water repellency, heat resistance and chemical resistance), and found that no holes were formed in the PET film. Issued. And if this film-shaped electrode is used, when the obtained electrodeless lamp is lit under high-temperature and high-humidity conditions, even if it is discharged in the gap, the film-side adhesive layer is not damaged, and Since water does not stay, the polyethylene terephthalate does not hydrolyze, so that no hole is formed in the PET film. Therefore, there is an advantage that a highly reliable electrodeless lamp can be obtained. In addition, when attaching a strip-shaped aluminum electrode to a transparent tubular body such as a cylindrical glass tube, simply peel off the separator from the film-shaped electrode and wind the electrode member around the outer periphery of the tubular body, and easily mount the electrodeless lamp. It has the advantage that it can be produced. Furthermore, a film-like electrode in which a plurality of electrode members are bonded to the band-shaped separator is supplied to the production line of the electrodeless lamp in that state, and the electrode member is mechanically peeled off from the band-shaped separator.
It has the advantage that it can be attached to a cylindrical body and can be continuously and automatically produced.

According to the method for producing a film-shaped electrode of the present invention, for example, a film with an electrode and a laminated film are simultaneously prepared in parallel, and then both are laminated to cut out a predetermined portion of the laminated film, and a connection terminal is formed. By simply attaching, a film-shaped electrode having a plurality of electrode members can be easily obtained. In addition, according to this manufacturing method, it is possible to provide a manufacturing process of the electrodeless lamp after the manufacturing process, and thus there is an advantage that continuous automatic production of the electrodeless lamp becomes possible. Furthermore, following the manufacturing process of the manufacturing method of obtaining the film-shaped electrode having the plurality of electrode members, if the band-shaped separator is cut so as to be one set of strip-shaped aluminum electrodes, the film-shaped electrode of another embodiment can be easily obtained. An electrode can be obtained.

[0011] In particular, in the above-mentioned production method, the step of preparing the electrode-attached film is performed by half-cutting a thin aluminum plate adhered to one surface of the strip-shaped separator at a predetermined interval in a direction orthogonal to the longitudinal direction thereof, and forming an electrode-formed portion adjacent to the electrode-formed portion. In the case where a plurality of strip-shaped aluminum electrodes are arranged side by side in a state perpendicular to the longitudinal direction on one surface of the strip-shaped separator by removing an unnecessary portion between This is advantageous from the viewpoint of sex. Also, when the above half cut is performed by a rotary cutter,
It is further advantageous from the viewpoint of productivity.

Further, according to the film-shaped electrode manufacturing apparatus of the present invention, a series of steps up to commercialization can be continuously performed in manufacturing the film-shaped electrode, which is advantageous in terms of cost in mass production. . In particular, when the manufacturing apparatus is provided with a means for cutting the strip-shaped separator for each set of two strip-shaped aluminum electrodes, it is advantageous since each set of film-shaped electrodes can be continuously manufactured.

According to the electrodeless lamp of the present invention, the luminous efficiency is higher and the luminous speed is higher than that of the cold cathode discharge tube lamp. It is.

In the present invention, "half cut"
The term “cut” refers to a cutting in which a laminate of two or more layers is not completely cut in the stacking direction, but is left without cutting at least one layer.

[0015]

Next, an embodiment of the present invention will be described.

FIG. 1 shows an embodiment of the film-shaped electrode of the present invention, and FIG. 2 is a sectional view taken along line XX of FIG. As shown in the figure, the film electrode 11 is a PET film 4
A pair of strip-shaped aluminum electrodes 2 having a connection terminal 13 at one end with a film-side pressure-sensitive adhesive layer 12 on one side
Have electrode members 14 arranged side by side. An adhesive layer 7 for adhering an electrode is formed on the exposed surface of the strip-shaped aluminum electrode 2 (the surface opposite to the surface on which the PET film 4 is bonded). The electrode member 14 is detachably attached to one surface of the separator 8 by utilizing the adhesive force of the film-side pressure-sensitive adhesive layer 12 and the electrode sticking pressure-sensitive adhesive layer 7.

The PET film 4 used for the film-shaped electrode 11 of the present invention has an advantage that it has transparency and is not colored or discolored by a change in light or temperature.

As a material for forming the film-side pressure-sensitive adhesive layer 12, a silicone-based pressure-sensitive adhesive is used. This silicone adhesive has a siloxane bond [-(SiO) n-]
And has excellent heat resistance, water repellency, electrical insulation (high volume resistivity), chemical resistance, and aging resistance due to the siloxane bond. Also,
Since this silicone-based pressure-sensitive adhesive is resistant to light and temperature changes, it has the advantage that its adhesive strength does not decrease even when used in an electrodeless lamp, and that excellent adhesive strength can be maintained for a long period of time. A specific example of such a silicone-based pressure-sensitive adhesive is PSA6574 manufactured by Toshiba Silicone Co., Ltd.

The connection terminal 13 is not particularly limited as long as it can transmit a current from an AC power supply to the strip-shaped aluminum electrode 2, and a conventionally known connection terminal is used.

As a material for forming the pressure-sensitive adhesive layer 7 for adhering the electrode formed on the exposed surface of the strip-shaped aluminum electrode 2, an acrylic acid ester is preferable because the electrode member 14 can be firmly adhered to a glass tube and can be obtained at low cost. Acrylic pressure-sensitive adhesives containing a copolymer as a main component are preferred. That is, since the acrylic pressure-sensitive adhesive is resistant to light and temperature changes, its adhesive strength does not decrease even when used in an electrodeless lamp, and excellent adhesive strength can be maintained for a long period of time. The acrylic pressure-sensitive adhesive includes a non-color-change type curing agent (for example, Coronate HL manufactured by Nippon Polyurethane Industry Co., Ltd.) and an antioxidant (for example, ADK STAB AO-6 manufactured by Asahi Denka Kogyo KK).
Conventionally known compounds such as 0) can be blended. The amounts of these components are set in consideration of not deteriorating the adhesive strength of the acrylic pressure-sensitive adhesive.
It is preferably set to 5 parts by weight or less with respect to parts by weight.

As the acrylate-based copolymer, the following adhesive component (component (A)), aggregating component (component (B)), and modifying component (component (C)) are known in the art. Those polymerized by the method are preferred. As the pressure-sensitive adhesive component (component (A)), alkyl acrylates having an alkyl group having 4 to 12 carbon atoms and alkyl groups having a carbon number of 4 are preferable from the viewpoint that tackiness can be imparted to the obtained copolymer.

Examples of the aggregating component [component (B)] include alkyl acrylates having 1 to 4 carbon atoms in an alkyl group, alkyl methacrylates having 1 to 4 carbon atoms in an alkyl group,
Examples include vinyl acetate, styrene, acrylonitrile, vinylidene chloride and the like. Examples of the modifying component [(C) component] include those which provide a carboxyl group such as acrylic acid and methacrylic acid, and hydroxyethyl acrylate because the resulting copolymer can be modified so as to have good physical properties. Those that provide hydroxyl groups such as hydroxyethyl methacrylate and propylene glycol monoacrylate, those that provide amide groups such as acrylamide and methacrylamide, and those that provide epoxy groups such as glycidyl acrylate and glycidyl methacrylate. Can be

Further, the material of the strip-shaped separator 8 provided by utilizing the film-side pressure-sensitive adhesive layer 12 and the electrode-adhesive pressure-sensitive adhesive layer 7 is not particularly limited, but the pressure-sensitive adhesive is firmly adhered. A conventionally known PET for a separator that can be adhered to a degree that can be peeled off without being used is preferably used. In addition, the PET for the separator is a normal PE.
The surface of T is subjected to a release treatment.

The film-shaped electrode of the present invention is manufactured, for example, as follows. That is, first, an adhesive is applied to one surface of the strip-shaped separator 8 using a comma coater, a lip coater, a reverse coater, a fauten coater, a gravure coater, or the like, and the adhesive layer 7 for electrode attachment is applied.
Is formed, and a base material 20 for an aluminum electrode (a roll-shaped wound body, see FIG. 3) is prepared by dry laminating a strip-shaped aluminum thin plate on the surface of the adhesive layer 7 for attaching an electrode. Then, as shown in FIG. 3, the aluminum thin plate on the surface is half-cut by an aluminum thin plate half-cutting device 21 while the aluminum electrode base material 20 is unwound in a strip shape, thereby exhibiting a strip-like aluminum electrode shape ( The cut portion is indicated by a broken line 2 '). The half-cutting device 21 is not particularly limited, but
A rotary cutter is preferable because continuous processing can be performed at high speed. And the unnecessary aluminum removing device 22
By stripping the unnecessary portion of the aluminum thin plate in order, a pair of strip-shaped aluminum electrodes 2 is formed. In this manner, a plurality of sets of strip-shaped aluminum electrodes 2 and a band-shaped separator 8
Is obtained, and is wound up in a roll. When the unnecessary aluminum portion is peeled off, it is preferable that the adhesive layer 7 for electrode attachment at that portion is removed together with the unnecessary aluminum portion.

On the other hand, on one surface of the belt-shaped PET film 4,
Comma coater, lip coater, reverse coater,
An adhesive is applied by a fauten coater, a gravure coater or the like to prepare a laminated film 24 on which the film-side adhesive layer 12 is formed. The width of the strip-shaped PET film 4 is usually the same as the width of the strip-shaped separator 8, but in consideration of exposing the connection terminals 13 to the outside of the PET film 4, May be shorter than the width. When the laminated film 24 is formed into a roll-shaped wound body so as to be easily stored or transported, a pressure-sensitive adhesive layer protective separator is attached to the surface of the film-side pressure-sensitive adhesive layer 12, and this is used during use. The adhesive layer protective separator may be peeled off.

Then, as shown in FIG. 4, the electrode-attached film 23 and the laminated film 24 (both roll-shaped winding bodies) are fed out and passed between opposing movable rollers 25 and 26, whereby the electrode The surface of the attached film 23 on which the strip-shaped aluminum electrodes are arranged and the surface of the laminated film 24 on which the film-side pressure-sensitive adhesive layer 12 is formed are joined to integrate them. At this time, an ear separator 27 is preferably interposed between the electrode-attached film 23 and the laminated film 24 as shown in the figure so that the connection terminal 13 can be easily attached to one end of the strip-shaped aluminum electrode 2. In the integrated film, the strip-shaped aluminum electrode 2
It is preferable that the separator 8 is covered with the PET film 4 so that the separator 8 keeps a flat state. That is, in such a case, when the separator 8 is removed and the electrode member 14 is attached to the cylindrical glass tube,
This is because a gap created by the thickness of the strip-shaped aluminum electrode 2 or the like can be reduced.

Next, at least a part of the PET film 4 between one set of the strip-shaped aluminum electrodes 2 and another set of the strip-shaped aluminum electrodes 2 adjacent to the one piece is cut from the integrated film into a PET film half. Cutting equipment 2
At 8 a cut is made (P 'shown in FIG. 4). Note that the cut P ′ is formed for the purpose of individually covering a set of strip-shaped aluminum electrodes 2 with the PET film 4. Even if the cut P ′ is two lines having a certain width, A single line is acceptable.

Subsequently, when a laminated film 24 having the same width as or larger than the electrode-attached film 23 is used, both edges in the longitudinal direction of the strip-shaped PET film 4 are unnecessary, and are removed ( E) shown in FIG. Further, at this time, as described above, if the cut P ′ formed by the PET film half-cutting device 28 has a certain width, an unnecessary portion is formed between the two lines P ′. ,
This is also removed (F shown in FIG. 4). Next, in order to attach the connection terminal 13 to one end of the strip-shaped aluminum electrode 2, a part (K shown in FIG. 4) of the PET film 4 inside the cut P ′ is lifted together with the ear separator 27, and the exposed strip is exposed. A conventionally known thermosetting conductive adhesive is applied to the surface of the aluminum electrode 2 by a dispenser 29. Thereafter, the connection terminal 13 is mounted on one end of the strip-shaped aluminum electrode 2 by placing the connection terminal 13 on the application surface. And PET film 4
In order to expose the connection terminal 13 of the strip-shaped aluminum electrode 2 to the outside from one longitudinal edge of the ear separator 27,
While peeling, the peeled PET film 4 is attached again. Thus, the film-shaped electrode 11 'of the present invention shown in FIG. 5 can be obtained. This is a mode different from the film-shaped electrode 11 shown in FIGS. 1 and 2, in which a plurality of electrode members 14 are formed on the surface of the strip-shaped separator 8. In addition, the film-shaped electrode 11 ′ in which the gap P is formed as shown in FIG.
It has the advantage that it can be easily supplied to the electrodeless lamp production line because it is easily mechanically detached from the lamp. Then, the film-shaped electrode 11 ′ of the present invention may be formed into a roll-shaped wound body while sandwiching the mirror sheet 30 as shown in FIG. 4 so as not to be damaged during storage or transportation.

Then, in the film-like electrode 11 ', the separator 8 is cut along a dashed line S shown in FIG. 5, and the film-like electrode according to the first embodiment of the present invention shown in FIGS. 11 (in which only a pair of strip-shaped aluminum electrodes 2 are arranged side by side) can be obtained.

The film-like electrode 1 thus obtained
1, 11 'is used as an electrode of an electrodeless lamp by removing the separator 8 and disposing it in a glass tube. Even when the electrodeless lamp thus obtained is turned on, the film-side pressure-sensitive adhesive layer 12 is formed of a material containing a silicone-based pressure-sensitive adhesive. Even if a discharge is caused in a gap created by the thickness, a hole is not formed in the PET film 4. Therefore, a highly reliable electrodeless lamp can be obtained by using the film electrodes 11 and 11 'of the present invention.

The thickness of the film-side pressure-sensitive adhesive layer 12 is preferably set in the range of 2 to 100 μm in consideration of protecting the PET film 4 electrically and chemically. More preferably, it is in the range of 5 to 50 μm.

Further, the thickness of the pressure-sensitive adhesive layer 7 for attaching an electrode is set to 2 to 100 μm in consideration of making the gap smaller.
m is preferably set in the range of m. More preferably, it is in the range of 10 to 50 μm.

Next, an example of the electrodeless lamp of the present invention is shown in FIGS. This includes a glass tube 50 whose both ends are closed, an insulating resin 51 for securing insulation between both connection terminals 13, a fluorescent paint 52 applied to the inner peripheral surface of the glass tube 50, The electrode member 14 is attached to the outer peripheral surface of the glass tube 50. The above electrode member 1
Numeral 4 is attached to the outer peripheral surface of the glass tube 50 in a state where the strip-shaped aluminum electrode 2 with connection terminals is placed inside and the PET film 4 is covered from the outside. Also,
The set of strip-shaped aluminum electrodes 2 with connection terminals are disposed in a mutually facing state in order to effectively excite the rare gas sealed in the glass tube 50 to increase the illuminance, and For the sake of wiring, etc., both connection terminals 13
Is attached to the glass tube 50 while being positioned at the other end opening. And the fluorescent paint 52 is
The coating is applied to the inner peripheral surface of the glass tube 50 with only one of the gaps formed between the strip-shaped aluminum electrodes 2 with connection terminals provided therebetween, thereby improving the illuminance. I have.

Next, examples will be described together with comparative examples.
