Detailed ways

The technical solutions in the embodiments of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The application provides a film-coated panel assembly 1, please refer to Figure 1 and Figure 2 together, Figure 1 is a schematic top view of the film-coated panel assembly provided in an embodiment of the present application; Figure 2 is along the I-I line in Figure 1 A schematic diagram of a partial cutaway. The film-covered plate assembly 1 includes a transparent plate 11 and a film layer 12, the film layer 12 is arranged on one side of the transparent plate 11, the film layer 12 has a film removal area 13, and the film removal area 13 There are a plurality of annular film removal units 131 arranged in an array, the part of the film layer 12 corresponding to the film removal unit 131 is removed, and the area ratio of the film removal unit 131 to the film removal area 13 is less than or Equal to 10%.

It should be noted that the film layer 12 is provided on one side of the transparent plate 11, and according to the different materials used in the film layer 12, the film layer 12 can absorb/reflect ultraviolet rays and infrared rays, so that the film layer 12 The board assembly 1 has the function of absorbing/reflecting ultraviolet rays and infrared rays. For most of the materials used in the film layer 12 , the transmittance of communication electromagnetic wave signals carrying data through the film layer 12 is relatively low. Then, when the film-covered panel assembly 1 is applied to a scene requiring communication functions, for example, online LOW-E glass, offline LOW-E glass, etc., the part of the film layer 12 that passes the communication electromagnetic wave signal will be removed, so that the communication electromagnetic wave signal can pass through the film-coated plate assembly 1 with a relatively large transmittance, and realize the communication function.

In the prior art, the area ratio of the film removal unit 131 to the film removal area 13 reaches 100%, which is contrary to the function of the film-coated plate assembly 1, and the absorption/absorption of the film removal area 13 The function of reflecting ultraviolet rays and infrared rays fails. The more commonly used film removal scheme is to design patterns for different communication bands, such as using laser film removal to perform grid film removal on the film layer 12, but usually the film removal unit 131 accounts for 17% of the area ratio of the film removal area 13, In this way, the signals around the 6.3GHz and 8.3GHz frequencies are turned on. For lower common frequencies, such as 5.8GHz of Electronic Toll Collection (ETC) and 1.5GHz of Global Positioning System (Global Positioning System, GPS), the area ratio of film removal unit 131 to film removal area 13 will be higher.

On the other hand, in terms of the realized process technology, the fine film removal process of glass usually adopts the laser film removal process. The speed of laser film removal and marking is generally 3m/s-10m/s. The higher the speed, the higher the laser power required and the lower the laser life. Therefore, the commonly used marking speed is about 5m/s. Assuming a marking speed of 10m/s, for a grid area of 500mm*500mm, the film removal time is 50s, barely reaching the production capacity of LOW-E coated glass. It is understandable that the film removal efficiency is mainly restricted by the film removal area, such as the application of LOW-E glass, the film removal efficiency of the grid pattern is generally 20mm ² /s-625mm ² /s, which cannot be etched on the entire glass , limiting the application scenarios of LOW-E glass. Therefore, the smaller the ratio of the area of the film removal unit 131 to the film removal region 13 is, the lower the technical difficulty of the process is.

It can be understood that in this embodiment, the film removal unit 131 has a specific pattern, so that the area ratio of the film removal unit 131 to the film removal region 13 is less than or equal to 10%, so as to avoid excessive The film layer 12 is removed, so that the film-covered plate assembly 1 retains the function of isolating purple and infrared rays, and improves the transmittance of electromagnetic wave signals in various frequency bands. At the same time, the film removing units 131 arranged in an array make the removed part of the film layer 12 relatively regular, and the overall appearance of the film-coated plate assembly 1 is relatively continuous.

It can be understood that, according to the actual electromagnetic wave signal passing through the area of the film-covered plate assembly 1, the area of the film removal area 13 can be less than or equal to 5% of the area of the transparent plate 11, for example, 100m*100m A small area may also be a 20%-50% half coverage area, or a 100% full coverage area, which is not limited in this application.

Next, the specific pattern design of the film removing unit 131 will be described in some possible implementation manners.

In a possible implementation manner, the film removal unit 131 includes a plurality of first film removal subunits 1311 and a plurality of second film removal subunits 1312, by setting the first film removal subunits 1311 for permeation The electromagnetic wave signal passing through the first frequency band is configured by setting the second film removing subunit 1312 to pass through the electromagnetic wave signal of the second frequency band, wherein the first frequency band is lower than the second frequency band.

Specifically, the design patterns of the first film removal subunit 1311 and the second film removal subunit 1312 are different, so that the film layer 12 corresponds to the first film removal subunit 1311 and the second film removal subunit 1312. The removed part of the membrane subunit 1312 is different, so that the frequency bands of the membrane layer 12 corresponding to the electromagnetic wave signals that the first membrane removal subunit 1311 and the second membrane removal subunit 1312 can pass are also different.

In this embodiment, the first frequency band is between 1 GHz and 4 GHz, and the second frequency band is between 2 GHz and 8 GHz. More preferably, the first frequency band is between 2.4GHz-2.6GHz, and the second frequency band is between 4.8GHz-5.8GHz.

Specifically, the first frequency band is between 1GHz-4GHz, that is to say, the first frequency band is an electromagnetic wave signal of a relatively commonly used lower frequency band; the second frequency band is between 2GHz-8GHz, that is to say, the The second frequency band mentioned above is an electromagnetic wave signal of a relatively commonly used higher frequency band.

It can be understood that, in other possible implementation manners, the first frequency band and the second frequency band may also be between other frequency bands, which is not limited in the present application.

In a possible implementation manner, please refer to FIG. 1 and FIG. 3 together. FIG. 3 is a partially enlarged schematic diagram of a part marked with a dashed line in FIG. 1 . A plurality of the first film removal subunits 1311 are arranged at intervals in the first direction _D1 , a plurality of the second film removal subunits 1312 are arranged at intervals in the first direction _D1 , and the first removal The membrane subunits 1311 and the second membrane removal subunits 1312 are alternately arranged in the second direction _D2 , wherein the first direction _D1 and the second direction _D2 are perpendicular to each other.

Specifically, the first direction _D1 and the second direction _D2 are shown by arrows in FIG. 3 . The pattern shown in FIG. 3 is the design pattern of the film removal unit 131 of the unit in this embodiment. In the annular closed area of the first film removal subunit 1311 and the second film removal subunit 1312, the corresponding The film layer 12 part will be removed.

It should be noted that, in this embodiment, the shape of the first film removal subunit 1311 and the second film removal subunit 1312 is square, and in other possible implementation manners, the first film removal subunit The unit 1311 and the second film removal subunit 1312 can also have other shapes, and the shapes of the first film removal subunit 1311 and the second film removal subunit 1312 can be the same or different , this application is not limited to this.

In this embodiment, the outer perimeters of the corresponding edges of the first film removal sub-unit 1311 and the second film removal sub-unit 1312 are different.

Specifically, the edge corresponding to the first film removal subunit 1311 and the second film removal subunit 1312 means that the ring-shaped outer edge of the first film removal subunit 1311 and the second film removal subunit The ring-shaped outer edge of the unit 1312 is compared, or the ring-shaped inner edge of the first film removal sub-unit 1311 is compared with the ring-shaped inner edge of the second film removal sub-unit 1312 . When the first film removal subunit 1311 and the second film removal subunit 1312 have different peripheral perimeters, the annular area of the first film removal subunit 1311 and the second film removal subunit 1312 Also different. It can be understood that the frequency of the electromagnetic wave signal passing is related to the annular area of the membrane removal unit 131, and the larger the annular area of the membrane removal unit 131, the lower the frequency of the electromagnetic wave signal that can pass through; vice versa, so The smaller the annular area of the film removing unit 131, the higher the frequency of the electromagnetic wave signal that can pass through.

It can be understood that in this embodiment, by designing the first membrane removal sub-unit 1311 and the second membrane removal sub-unit 1312 to have different edge outer perimeters, it is possible to realize multi-band electromagnetic wave signals with higher transparency. Overpass, or increase the communication frequency bandwidth of electromagnetic wave signals.

In this embodiment, the area ratio of the film removal unit 131 to the film removal area 13 is less than or equal to 8%, or more preferably less than or equal to 5%.

Specifically, removing the film layer 12 with the design pattern of the film removing unit 131 can make the area ratio of the film removing unit 131 occupying the film removing region 13 less than or equal to 5%. It can be understood that the smaller the area ratio of the film removal unit 131 to the film removal area 13 is, the more continuous and beautiful the overall appearance of the film-coated plate assembly 1 is.

In a possible implementation manner, please also refer to FIG. 4 , which is a schematic diagram of a pattern of a film removal unit provided in an embodiment of the present application. A plurality of the second film removal subunits 1312 are arranged at intervals in the area surrounded by the first film removal subunits 1311 .

Specifically, in this embodiment, the outer circumference of the edge of the single first membrane removal subunit 1311 is longer than the corresponding edge outer circumference of the second membrane removal subunit 1312, therefore, the first membrane removal The part of the transparent plate 11 corresponding to the subunit 1311 is used for passing electromagnetic wave signals of a lower frequency band, and the part of the transparent plate 11 corresponding to the second film removing subunit 1312 is used for passing electromagnetic wave signals of a higher frequency band.

In this embodiment, the periphery of the single second film removing subunit 1312 is at least partially overlapped with the periphery of the first film removing subunit 1311 . Wherein, the overlapped part accounts for the sum of the lengths of the outer sides of the plurality of second membrane subunits 1312 , and is between 30% and 50%, preferably 40%.

It can be understood that this arrangement utilizes the overlapping portion of the first film removal subunit 1311 and the second film removal subunit 1312 to further reduce the removed part of the film layer 12, and at the same time, fully The wave-transparent area of all electromagnetic waves is utilized. In this embodiment, the area ratio of the film removal unit 131 to the film removal area 13 is less than or equal to 10%, which can achieve a relatively low film removal area ratio.

Specifically, please refer to FIG. 5 together. FIG. 5 is a schematic diagram of the attenuation performance of the film-coated panel assembly provided in an embodiment of the present application. As shown in FIG. 5 , the abscissa is the frequency band of the electromagnetic wave signal passing through the film-coated panel assembly 1 , and the ordinate is the attenuation of the electromagnetic wave signal after passing through. 5, it can be concluded that the pattern design of the film removal unit 131 in this embodiment can make the electromagnetic wave signal passability of the film-coated panel assembly 1 after film removal in this way be between 2.4GHz and 5.8GHz. It is roughly the same as the glass without the film layer 12.

In a possible implementation manner, please refer to FIG. 6 together. FIG. 6 is a schematic diagram of a pattern of a film removal unit provided in another implementation manner of the present application. The first film removal subunit 1311 includes a first film removal part 131a and a plurality of second film removal parts 131b extending from the first film removal part 131a, and the first film removal part 131a is arranged on multiple The gaps between the second film removal subunits 1312 are connected to a plurality of the second film removal subunits 1312, and the plurality of second film removal parts 131b are respectively connected to the corresponding second film removal subunits 131b. The peripheral edges of the membrane subunits 1312 are at least partially overlapped.

Specifically, the first film removal part 131a is inscribed in a plurality of the second film removal subunits 1312, that is, the first film removal part 131a and the plurality of second film removal subunits 1312 There is no overlapping portion, and each of the second film removing parts 131b of the first film removing part 131a is at least partially overlapped with the corresponding peripheral edge of the second film removing subunit 1312 .

The first film removal part 131a is a small square in the middle of a "well" shape, and the second film removal part 131b is formed by extending the side length of the small square of the first film removal part 131a. In this embodiment, the adjacent and vertical second film removing parts 131b overlap with two adjacent sides of a corresponding one of the second film removing subunits 1312 .

It should be noted that each of the second film removal parts 131b is formed by extending the side lengths of the first film removal parts 131a in opposite directions, and the extension length of each second film removal part 131b, The widths can all be different. In other possible implementation manners, as long as the at least partial overlapping arrangement of the first film removal subunit 1311 and the second film removal subunit 1312 is not affected, The shape of the second film removing subunit 1312 is not limited either.

In this embodiment, as shown in FIG. 6 , the part of the transparent plate 11 corresponding to the second film removal subunit 1312 is used to pass electromagnetic wave signals of a higher frequency band, while the first film removal subunit 1311 corresponds to The part of the transparent plate 11 can pass the electromagnetic wave signal of the lower frequency band, that is to say, the overlapping part of the second film removing part 131b and the second film removing subunit 1312 can pass through the higher and lower parts at the same time. Frequency band electromagnetic wave signal.

It should be added that, compared with FIG. 4 , when the film layer 12 of this embodiment is used for heat conduction and/or electric conduction, since the outer periphery of the film removal unit 131 is not closed, the film layer on the inner periphery of the film removal unit 131 12 may communicate with the membrane layer 12 except the outer periphery of the membrane unit 131 , and the thermal conductivity and/or electrical conductivity of the entire membrane layer 12 are better.

Specifically, please refer to FIG. 8 together. FIG. 8 is a schematic diagram of attenuation performance of a film-coated panel assembly provided in another embodiment of the present application. As shown in FIG. 8 , the abscissa is the frequency band of the electromagnetic wave signal passing through the film-coated panel assembly 1 , and the ordinate is the attenuation of the electromagnetic wave signal after passing through. 8, it can be concluded that the pattern design of the film removal unit 131 in this embodiment can make the film-coated board assembly 1 meet the mobile 5G dual-band (2.6GHz, 4.9GHz, 2.6GHz, 4.9 GHz) communication function. At 2515MHz-2675MHz and 4800MHz-4900MHz, the attenuation is less than 5dB relative to the glass without the film layer 12, which meets the transparent requirement of the coated glass for the 5G signal on the vehicle.

In a possible implementation manner, please refer to FIG. 4 again, the gap between the plurality of second film removal subunits 1312 is W ₁ , one side of the first film removal subunit 1311 is connected to the The distance of one side corresponding to the membrane unit 131 is W ₂ , which satisfies W ₁ =K*W ₂ , wherein the value of K is between 1.5-2.5.

It can be understood that the above values are achieved with a relatively low film removal area ratio, which is an application of mass production of the laser large-area film removal solution. In other possible implementation manners, the D outer side length of the membrane-except unit 131, the _L1 outer side length of the first membrane-except subunit 1311 and the _L2 outer side length of the second membrane-except subunit 1312 can also be are other numerical values, which are not limited in this application.
