Description

  The present invention relates to an antenna-enclosed laminated glass in which an antenna element is enclosed between glass plates and a method for manufacturing the same.

  Conventionally, an antenna sheet in which a conductor layer serving as an antenna element and an adhesive layer are formed on a base material sheet is known (for example, see Patent Document 1). This antenna sheet can function as a glass antenna by being adhered to the surface of glass by the adhesive layer.

  By the way, such an antenna sheet is affixed on the surface of glass. For this reason, for example, when it adheres to the vehicle inner surface of the front windshield of a vehicle, it is necessary to cover the said conductor layer with a transparent protective layer. The protective layer is provided to prevent the conductor layer from being damaged and broken by an external force. Since the protective layer has a refractive index different from that of the glass, the boundary line between the glass and the glass may be visible or the glass may be covered with a relatively large area. For this reason, such an antenna seat has a problem of appearance and a problem that is obstructive to a vehicle occupant.

  On the other hand, in an antenna-enclosed laminated glass in which an antenna element is enclosed between glass plates (see, for example, Patent Document 2), the antenna element is protected by a glass plate. Even when the antenna-enclosed laminated glass is applied to automobile glass, problems such as appearance due to the protective layer do not occur in a region other than the antenna element.

Such an antenna-enclosed laminated glass includes a print type in which a conductive paste is printed in a predetermined pattern on the inner surface (mating surface) of a glass plate to constitute an antenna element, and an intermediate film (typically polyvinyl alcohol) interposed between the glass plates. There is an intermediate film embedded type in which an antenna wire is embedded in a film made of butyral.
JP 2001-119219 A Japanese Patent Laid-Open No. 2-82701

  In the above-described print type, since the line resistance is large, in order to ensure desired antenna performance, the line width of the antenna pattern has to be increased, and the problems from the viewpoint of appearance and the like are still not solved.

  In this respect, the above-described intermediate film embedded type is advantageous from the viewpoint of appearance and the like because an antenna wire having a small wire diameter can be embedded in the intermediate film.

  However, since laminated glass is manufactured by sandwiching an intermediate film between two glass plates and undergoing pressure bonding and heat treatment, in the above-mentioned intermediate film embedded type, the intermediate film embedded with the antenna wire is not bonded. In the heat treatment process, the antenna wire may be stretched and the position of the antenna line may be shifted accordingly. Such a misalignment tendency causes a problem from the viewpoint of antenna performance, and becomes a major factor that the position of the antenna pattern varies from product to product, and also causes a problem from the viewpoint of stability of the antenna performance.

  Accordingly, an object of the present invention is to provide a method for manufacturing an antenna-enclosed laminated glass capable of manufacturing an antenna-enclosed laminated glass having a good appearance and the like in a manner in which the antenna pattern is not easily displaced during the manufacturing process. To do.

In order to solve the above problems, according to one aspect of the present invention, an antenna element is enclosed between a plurality of glass plates of a laminated glass in which a plurality of glass plates are bonded together through an intermediate film made of a resin. A method of manufacturing an antenna-enclosed laminated glass,
Forming the plurality of glass plates into a predetermined curved shape;
A laminating step of laminating the plurality of glass plates and the intermediate film;
A crimping step of crimping the plurality of glass plates via the intermediate film between the plurality of glass plates,
Further, in the lamination step, the laminated sheet material including the conductor layer and the adhesive layer constituting the antenna element is bonded to the surface of the at least one glass plate facing the intermediate film by the adhesive layer. There is provided a method for producing a laminated glass comprising a sheet adhering step and a step of forming a laminate of the plurality of glass plates, an antenna element and an intermediate film.

  In this aspect, the conductor layer may include a linear portion of a predetermined pattern having a line width in a range of 0.15 to 0.4 mm. The surface to which the laminated sheet material is bonded may be a convex surface of the one glass plate having a curvature.

According to another aspect of the present invention, an antenna encapsulating type in which an antenna element is enclosed between a plurality of glass plates of laminated glass in which a plurality of glass plates are bonded via an intermediate film made of a resin. Laminated glass,
The antenna element is configured by fixing a conductor layer with an adhesive layer to a surface of at least one glass plate of the plurality of glass plates facing the intermediate film. An antenna-enclosed laminated glass is provided.

  As described above, according to the present invention, the step of crimping the glass plate through the intermediate film is performed in a state where the conductor layer constituting the antenna element is adhered to the surface (mating surface) of the glass plate by the adhesive layer. Therefore, an antenna-enclosed laminated glass with high positional accuracy of the antenna element is manufactured without causing the antenna element (conductor layer) to be displaced with respect to the glass plate as the intermediate film expands and contracts during the crimping process. be able to. Further, by making the line width of the conductor layer constituting the antenna element within the range of 0.15 to 0.4 mm, it is possible to obtain an antenna-enclosed laminated glass having a good appearance and the like.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 shows an application example of an antenna-enclosed laminated glass according to the present invention. The antenna-enclosed laminated glass 10 is normally used as a front windshield of an automobile as in this application example, but may be used as a side glass or a rear glass of an automobile.

  The laminated glass 10 is obtained by press-bonding a plurality of glass plates 12 through an intermediate film 14 (see FIG. 8) between them. The intermediate film 14 is made of, for example, polyvinyl butyral (PVB).

  An antenna element 20 is enclosed between glass plates 12 constituting the laminated glass 10 as will be described later. As shown in FIG. 1, the antenna element 20 has a predetermined pattern, and receives, for example, a radio wave from a television station or a radio station, a radio wave from a mobile phone, or a radio wave from a satellite. Good. In this way, in this embodiment, since the antenna element 20 is sealed between the glass plates 12, the antenna element 20 is protected by the glass plate 12.

  FIG. 2 is a process diagram showing the main part of the manufacturing process of the antenna-enclosed laminated glass according to the present invention. Hereinafter, for the sake of explanation, it is assumed that the laminated glass 10 is composed of two glass plates 12, and when attached to the vehicle, a reference numeral 12a is provided on the glass plate that is on the outside of the vehicle, and a reference numeral 12b is provided on the glass plate that is on the inside of the vehicle. Attached.

  As shown in FIG. 2, the manufacturing process of the laminated glass of a present Example consists of the glass forming process 100, the antenna sheet adhesion process 120, and the glass bonding process 140.

  In the glass forming process 100, the two base plates are separately subjected to a cutting / chamfering process (step 101) and a clean drying process (step 102). Of the two base plates, the base plate (inner plate) that constitutes the glass plate 12b on the vehicle inner side is printed on the edge of the glass plate 12b (step 103). This print may be provided on the edge of the vehicle outer side glass plate 12a, or may be provided on both the vehicle outer side and the vehicle inner side. Thereafter, the two plates are overlapped with each other (step 104), and the edges are placed on the mold in a state where the two plates are overlapped. Next, the stacked glass plates are heated to a temperature equal to or higher than the softening point, and are bent into a curved shape by their own weight (step 105). Then, after receiving a slow cooling process (step 106), both plates are separated again (step 107). Thereby, the glass plates 12a and 12b having surfaces having substantially the same curvature are formed. The glass plates 12a and 12b then move to the antenna sheet bonding step 120 through a cleaning / drying step (step 108).

  In the antenna sheet bonding step 120, the antenna sheet 30 is affixed to the outer surface of the glass plate 12b. The vehicle outer surface of the glass plate 12b is the vehicle outer surface of the glass plate 12b on the vehicle interior side as described above, that is, the surface on the side facing the glass plate 12a when matching with the glass plate 12a. Hereinafter, it is referred to as “mating surface 13a”.

  As shown in FIG. 3, the antenna sheet 30 is a sheet material having a predetermined shape. As shown in FIG. 4 (cross section AA in FIG. 3), the antenna sheet 30 is a laminated sheet material including at least a conductor layer 32 and an adhesive layer 34 constituting the antenna element 20. The conductor layer 32 and the adhesive layer 34 are formed between a first release layer (mounting paper) 31a and a second release layer (protective film) 31b that define the predetermined shape. The first release layer is a mount for holding the antenna pattern of the conductor layer 32 until the conductor layer 32 and the adhesive layer 34 are fixed to the mating surface 13a of the glass plate. By providing the mount, the laminated sheet material can easily handle and fix the conductor layer, and can prevent deformation of the antenna pattern. The second release layer is a protective film that protects the conductor layer until the conductor layer 32 and the adhesive layer 34 are fixed to the mating surface 13a of the glass plate. By providing the protective film, the laminated sheet material can prevent deformation and disconnection due to external force of the antenna pattern of the conductor layer. Therefore, it is preferable that the second release layer is peeled off immediately before the laminated sheet material is disposed and bonded to the mating surface 13b. An adhesive layer 35 is interposed between the conductor layer 32 and the second release layer 31b. The adhesive layer 35 adheres the conductor layer 32 and the second release layer 31b with an easily peelable adhesive force. In addition, the slit 50 may be formed in the 1st peeling layer 31a for every predetermined area | region in consideration of the workability | operativity at the time of peeling.

  In the antenna sheet bonding step 120, first, the first release layer (mounting sheet) 31a is peeled off (step 121), and the antenna sheet 30 is arranged and bonded at a predetermined position on the mating surface 13a of the glass plate 12b (step 122). At this time, as shown in FIG. 5A, the conductor layer 32 is bonded to the mating surface 13a of the glass plate 12b by the adhesive layer. In addition, in order to ensure adhesion | attachment with this contact bonding layer 34 and the mating surface 13a, the process which presses the antenna sheet 30 with respect to the mating surface 13a of the glass plate 12b may be made.

  Next, as shown in FIG. 5B, the second release layer (protective film) 31b is peeled off from the conductor layer 32 together with the adhesive layer 35 (step 123). Thereby, the first peeling layer 31a and the second peeling layer 31b are removed, and only the conductor layer 32 and the adhesive layer 34 remain on the mating surface 13a of the glass plate 12b. As is apparent, the adhesive force between the adhesive layer 35 and the conductor layer 32 is adjusted to be sufficiently smaller than the adhesive force of the adhesive layer 34. The adjusted adhesive strength is such that the conductor layer 32 does not peel from the mating surface 13a of the glass plate 12b together with the adhesive layer 34 or the conductor layer 32 does not peel from the adhesive layer 34 when the second release layer 31b is peeled off. To the extent.

  Thereafter, as necessary, the end of the antenna element 20 is folded back from the edge of the glass plate 12b as a process for connecting the antenna element 20 (conductor layer 32) to the electrode 40 (see FIG. 8) (see FIG. 8). ) May be performed (step 124).

  When the antenna sheet bonding step 120 for the glass plate 12b is completed in this way, the process proceeds to a glass combining step 140 for combining the glass plate 12b and the glass plate 12a.

  In the glass combining step 140, a laminate of the plurality of glass plates, the antenna elements, and the intermediate film, with an antenna element and an intermediate film for bonding the plurality of glass plates interposed between the plurality of glass plates. Are formed and pressed to obtain a laminated glass. First, the intermediate film 14 cut out in substantially the same shape as the glass plates 12a and 12b through the cleaning step and the film cutting step (steps 141 and 142) is inserted between the glass plates 12a and 12b (step 143). In this way, the intermediate film 14 is interposed between the mating surface 13a of the glass plate 12b to which the above-described conductor layer 32 is bonded and the mating surface of the glass plate 12a to obtain a laminate. Next, both the glass plates 12a and 12b are preliminarily pressure-bonded (step 144), and then a main pressure-bonding process using an autoclave (pressure cooker) is performed (step 145). As a result, the bonding surfaces between the glass plates 12a and 12b and the intermediate film 14 are completely degassed and fused, and the laminated glass 10 is completed.

  By the way, in the step of degassing the air at the interface between the intermediate film 14 and the glass plate to completely press the glass plates 12a and 12b together, there is an effect of heat as well as pressure. Therefore, the intermediate film 14 contracts between the glass plates 12a and 12b. For this reason, in a configuration in which an antenna wire is formed on the intermediate film 14 side or another film in which an antenna pattern is printed is interposed between the intermediate film 14 and the glass plate 12, the expansion and contraction of the intermediate film 14 is accompanied. As a result, the antenna wire and film are likely to be misaligned.

  On the other hand, in this embodiment, as described above, the antenna element 20 is bonded to the mating surface 13a of the glass plate 12b with the adhesive layer 34 as the conductor layer 32. Therefore, the conductor layer 32 does not shift with respect to the mating surface 13a of the glass plate 12b as the intermediate film 14 expands and contracts. Thus, according to the present embodiment, the antenna element 20 does not shift in position with respect to the glass plate 12b during the manufacturing process. As a result, the positional accuracy of the antenna element 20 (antenna pattern) is improved, and desired antenna performance can be realized. Further, the variation in the position of the antenna element 20 (antenna pattern) that can occur for each product is greatly reduced, and the antenna performance can be stabilized.

  The positional accuracy of the antenna element 20 (antenna pattern) not only affects the electrical connection mode with the vehicle side, but also affects the positional relationship with a member that can be a surrounding ground when mounted. As a result, the position accuracy of the antenna element 20 may affect the antenna performance. As a specific example, when the antenna element 20 is mounted as a front windshield of an automobile, the positional relationship with the body pillar affects.

  This influence on the antenna performance is particularly noticeable when the antenna element 20 is for receiving high-frequency radio waves such as digital broadcasting. Therefore, the antenna-enclosed laminated glass 10 manufactured according to the present embodiment can exhibit desired antenna performance with little variation for each product even when used for such applications.

  In this embodiment, the antenna sheet 30 (conductor layer 32) is bonded to the mating surface 13a of the glass plate 12b on the convex surface side. In this case, in contrast to the case where the antenna sheet 30 is affixed to the concave side (for example, the inner surface of the glass plate 12a), the antenna sheet 30 is stretched during the affixing. Therefore, wrinkles are less likely to occur in the antenna sheet 30 and workability is improved. Further, since the conductor layer 32 is located on the vehicle inner side than the intermediate film 14 having the UV cut function, the weather resistance of the antenna element 20 is improved.

  In the present embodiment, the antenna sheet adhering step 120 may be realized through the manual operation of the operator, but may be automated using a robot or the like. Further, the antenna sheet 30 does not necessarily have to be delivered in a separated state. As another delivery form, the form wound by the roll as a continuous body which consists of several antenna sheet 30 separable from each other may be sufficient, and the thing of the form separated while winding from a roll on a line may be sufficient.

  FIG. 6 is a view showing another embodiment of the antenna sheet 30 other than that in FIG. 4, and corresponds to a cross-sectional view taken along the line AA in FIG.

  The antenna sheet 30 shown in FIG. 6A has a black layer 37 laminated on the inner side of the conductor layer 32 via an adhesive layer. The black layer 37 is made of a black paint having a low reflectance, and is provided so that the conductor layer 32 cannot be seen from the passenger compartment from the viewpoint of appearance. Further, the black layer 37 protects the conductor layer 32 and plays a role of increasing strength and stability. The antenna sheet 30 shown in FIG. 6B has black layers 37 on both sides of the conductor layer 32. As described above, the antenna sheet 30 may appropriately include various layers other than the conductor layer 32 and the adhesive layer 34. The thickness of each layer is set as appropriate. For example, the laminated sheet material shown in FIG. 6B may have an overall thickness D of about 0.3 mm. Here, an example is shown in which a black layer using a black paint is used as a print for shading. However, the black layer is not necessarily black, and can be used as long as it can shield visible light and ultraviolet rays, such as gray or dark brown.

  The conductor layer 32 may be formed from annealed copper or the like, the adhesive layer 34 or the adhesive layer 35 may be formed from an acrylic adhesive material, and the second release layer 31b may be formed from a polyester film, The first release layer 31a may be obtained by subjecting a single-sided polylaminate fine paper or a resin sheet (for example, PET) to a release treatment.

  The pattern of the antenna element 20 as shown in FIG. 3 is formed by punching a laminated sheet material of various layers as described above with a mold having a predetermined shape using a press. FIG. 7 shows how the laminated sheet material is punched when the antenna sheet 30 shown in FIG. 4 is manufactured. In this case, a laminated sheet material composed of the conductor layer 32 and the adhesive layer 34 is punched with a mold to a predetermined line width W.

  The line width W of the conductor layer 32 is 0.15 ≦ W ≦ 0.4 mm, preferably 0.2 ≦ W ≦ 0.3 mm, in the antenna pattern portion which is a portion excluding the end portion and the electrode portion. Thereby, the appearance of the laminated glass is improved, and it is advantageous from the viewpoint of not obstructing the occupant when used as automobile glass. Moreover, in the present Example, the example which forms the conductor layer 32 by punching a lamination sheet material was shown. However, the conductor layer may be formed by a method of printing using a conductor paste or a method of using a wire for the antenna wire. In addition, the adhesive layer may be formed by laminating the conductor layer before forming the pattern to form the adhesive layer, or after forming the pattern with the conductor layer, the adhesive layer may be formed on the surface thereof.

  After punching, the punched conductor layer 32 and adhesive layer 34 are combined with the first release layer 31a on the laminated sheet material composed of the second release layer 31b and the adhesive layer 35, and then passed through a roller to the antenna. The sheet 30 is completed.

  FIG. 8 is a perspective view showing a first embodiment of the electrode lead-out structure of the antenna element 20 in the antenna-enclosed laminated glass 10 manufactured according to the above-described embodiment.

  This embodiment relates to an antenna-enclosed laminated glass 10 manufactured using the antenna sheet 30 shown in FIG. In the present embodiment, the electrode extraction portion of the antenna element 20 is configured by a portion having a relatively large line width W of the conductor layer 32. That is, the conductor layer 32 of the present embodiment includes a thin line portion 32a having a line width W of 0.15 ≦ W ≦ 0.4 mm, and an extension portion 32b having a relatively large line width and made of the same material. The above-described punching is performed so that is formed.

FIG. 9 shows an XX cross section of FIG. A part of the thin line portion 32a and the extended portion 32b are bonded to the mating surface 13a of the glass plate 12b by the adhesive layer 34 as described above.
From FIG. 9, it can be seen that the conductor layer 32 bonded to the glass plate 12b with the adhesive layer 34 is embedded in the intermediate film 14 after the main pressure bonding step.

  As shown in FIG. 8, the extension 32b is folded back from the edge of the glass plate 12b to the surface 13b on the opposite side of the glass plate 12b. This folding is realized by folding and pasting the antenna sheet 30 to the surface 13b of the glass plate 12b along the folding line H shown in FIG. 3 in the antenna sheet bonding step 120 shown in FIG.

  An end portion of the extension portion 32b is connected to an electrode 40 formed, for example, by printing on the surface 13b side of the glass plate 12b. The connection between the end portion of the extension portion 32b and the electrode 40 may be realized by soldering after the above-described main crimping process (step 145).

  A vehicle-side amplifier (not shown) that amplifies the radio wave received by the antenna element 20 is connected to the electrode 40 via an electric wire (not shown). During antenna operation, radio waves received by the antenna element 20 are extracted through the electrode 40, subjected to predetermined processing (amplification processing, etc.) as necessary, and supplied to a predetermined in-vehicle media device such as a television. Note that the radio wave received by the antenna element 20 may be transmitted wirelessly to the media device via a Bluetooth transmitter or a wireless LAN transmitter connected to the electrode 40.

  FIG. 10 is a perspective view showing a second embodiment of the electrode extraction structure of the antenna element 20 in the antenna-enclosed laminated glass 10 manufactured according to the above-described embodiment.

  In the present embodiment, the electrode itself of the antenna element 20 is constituted by a portion of the conductor layer 32 having a predetermined shape. That is, in the conductor layer 32 of this embodiment, a thin line portion 32a having a constant line width with a line width W of 0.15 ≦ W ≦ 0.4 mm, and an electrode 32c having a predetermined shape region are formed. Has been punched. FIG. 11 shows an antenna sheet 30 corresponding to this embodiment.

  FIG. 12 shows an XX cross section of FIG. The thin line-shaped portion 32a and the electrode 32c are bonded to the mating surface 13a of the glass plate 12b by the adhesive layer 34 as described above. In the example shown in FIG. 12, the antenna sheet 30 having the laminated structure shown in FIG. 6A is used. In this way, the electrode 32c is sealed between the two glass plates 12a and 12b of the laminated glass 10 as the conductor layer 32.

  On the surface 13b side of the glass plate 12b, an electrode 40 is formed by printing, for example, at a position facing the electrode 32c. Thereby, the connection via the capacitive coupling (electromagnetic coupling) of the electrode 40 and the electrode 32c is implement | achieved. A vehicle-side amplifier (not shown) that amplifies the radio wave received by the antenna element 20 is connected to the electrode 40 via an electric wire (not shown). During antenna operation, radio waves received by the antenna element 20 are taken out through capacitive coupling between the electrode 40 and the electrode 32c, subjected to predetermined processing (amplification processing, etc.) as necessary, and external electric wires (not shown). To a predetermined in-vehicle media device such as a television. Note that the radio wave received by the antenna element 20 may be transmitted wirelessly to the media device via a Bluetooth transmitter or a wireless LAN transmitter connected to the electrode 40.

  In the present embodiment, it is not necessary to solder the connection between the electrode 40 and the antenna element 20 on the laminated glass 10, and the in-vehicle media device and the antenna element 20 can be connected through capacitive coupling. As a result, it is possible to prevent inconvenience that thermal stress is generated in the glass plates 12a and 12b due to heat generated during soldering.

  In the present embodiment, the electrode 32c is provided on the mating surface 13a of the vehicle interior side glass plate 12b. For this reason, the positional accuracy of the present embodiment is advantageous with respect to the displacement of the positional relationship between the electrode 32c and the electrode 40 as compared with the case where the electrode 32c is provided on the vehicle inner surface of the vehicle outer side glass plate 12a. Further, according to the present embodiment, the electrode 32c is bonded to the glass plate 12 as described above. For this reason, positional displacement between the electrode 32c and the electrode 40 due to the expansion and contraction of the intermediate film 14 hardly occurs, and highly reliable capacitive coupling can be obtained.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above description, an example in which the antenna sheet 30 is provided between the intermediate film 14 and the mating surface 13a of the vehicle interior glass plate 12b is disclosed as a preferred embodiment. It does not exclude any configuration provided between the membrane 14 and the outside glass plate 12a. Even in this case, the effect that the antenna element 20 can be bonded and formed with high positional accuracy inside the laminated glass 10 can be obtained.

  Further, the intermediate film 14 does not necessarily have to be a single layer, and a plurality of layers may exist between the two glass plates 12. The intermediate film 14 may have other functions such as a sound insulation function and a heat ray reflection function.
