Description of reference numerals: the film removing device comprises a film coating plate assembly-1, a transparent plate-11, a film layer-12, a film removing area-13, a film removing unit-131, a first film removing subunit-1311, a first film removing part-131 a, a second film removing part-131 b, a second film removing subunit-1312, a vehicle-2 and a vehicle frame-21.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Referring to fig. 1 and 2 together, fig. 1 is a schematic top view of a film coating plate assembly according to an embodiment of the present disclosure; fig. 2 is a schematic partial sectional view taken along line I-I in fig. 1. The film coating plate assembly 1 comprises 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 is provided with a film removing area 13, a plurality of annular film removing units 131 which are arranged in an array mode are arranged in the film removing area 13, the part, corresponding to the film removing units 131, of the film layer 12 is removed, and the area ratio of the film removing units 131 to the film removing area 13 is smaller than or equal to 10%.

The film layer 12 is disposed on one side of the transparent plate 11, and the film layer 12 can absorb/reflect ultraviolet rays and infrared rays according to the material used for the film layer 12, so that the film-coated plate assembly 1 has the function of absorbing/reflecting ultraviolet rays and infrared rays. For most of the materials used for the film layer 12, the transmittance of the data-carrying communication electromagnetic wave signal is low when the signal is transmitted through the film layer 12. Then, when the film plate assembly 1 is used in a scenario requiring a communication function, such as an online LOW-E glass, an offline LOW-E glass, or the like, the portion of the film layer 12 that passes the communication electromagnetic wave signal will be removed to enable the communication electromagnetic wave signal to pass through the film plate assembly 1 with greater transmittance, thereby achieving a communication function.

In the prior art, the ratio of the area of the film removing unit 131 to the film removing area 13 reaches 100%, which is contrary to the function of the coated film plate assembly 1, and the function of the film removing area 13 for absorbing/reflecting ultraviolet rays and infrared rays is ineffective. The more common film removing scheme is to design patterns corresponding to different communication bands, for example, a laser film removing is used to perform grid film removing on the film layer 12, but the area ratio of the film removing unit 131 to the film removing area 13 is usually 17%, so as to conduct signals at about 6.3GHz and 8.3GHz frequencies. For lower common frequencies, such as 5.8GHz of Electronic Toll Collection (ETC) and 1.5GHz of Global Positioning System (GPS), the area ratio of the membrane removing unit 131 to the membrane removing area 13 will be higher.

On the other hand, from the realized process technology, the fine film removing process of the glass generally adopts a laser film removing process. The scribing speed of the laser film removing is generally 3m/s-10m/s, the higher the speed is, the higher the required laser power is, and the shorter the laser service life is, so the scribing speed is usually about 5 m/s. If the scribing speed is 10m/s, the film removing time is 50s for a grid area of 500mm x 500mm, the production capacity of the LOW-E coated glass is barely achieved. As can be appreciated, the film removal efficiency is primarily limited to film removal areas such as those used for LOW-E glass, and the grid pattern removal efficiency is typically 20mm²/s-625mm²And/s, the whole glass cannot be etched, so that the application scene of the LOW-E glass is limited. Thus, it is possible to provideThe smaller the area ratio of the film removing unit 131 to the film removing region 13, the lower the difficulty of the process technology.

It can be understood that, in the present embodiment, the film removing unit 131 has a specific pattern, such that the area ratio of the film removing unit 131 to the film removing region 13 is less than or equal to 10%, and excessive portions of the film layer 12 are prevented from being removed, so that the film coating plate assembly 1 retains the function of separating the violet and infrared rays, and the transmittance of the electromagnetic wave signals of each frequency band is improved. Meanwhile, the film removing units 131 arranged in an array enable the removed portions of the film layer 12 to be regular, and the film coating plate assembly 1 is continuous in overall appearance.

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

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

In one possible embodiment, the membrane removing unit 131 comprises a plurality of first membrane removing subunits 1311 and a plurality of second membrane removing subunits 1312, wherein the first membrane removing subunits 1311 are configured to transmit electromagnetic wave signals of a first frequency band, and the second membrane removing subunits 1312 are configured to transmit electromagnetic wave signals of a second frequency band, wherein the first frequency band is lower than the second frequency band.

Specifically, the first membrane removing subunit 1311 and the second membrane removing subunit 1312 are designed in different patterns, so that the membrane layer 12 is different from the portion where the first membrane removing subunit 1311 and the second membrane removing subunit 1312 are removed, and the membrane layer 12 is different from the first membrane removing subunit 1311 and the second membrane removing subunit 1312 in frequency bands of electromagnetic wave signals capable of passing through.

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

Specifically, the first frequency band is between 1GHz and 4GHz, that is, the first frequency band is an electromagnetic wave signal of a relatively common lower frequency band; the second frequency band is between 2GHz-8GHz, that is, the second frequency band is a more commonly used electromagnetic wave signal of a higher frequency band.

It is to be understood that, in other possible embodiments, the first frequency band and the second frequency band may also be between other frequency bands, which is not limited in this application.

In one possible implementation, please refer to fig. 1 and fig. 3 together, and fig. 3 is a partially enlarged schematic view of a dashed-line box portion a in fig. 1. A plurality of the first membrane removing subunits 1311 in a first direction D₁Are arranged at intervals, and a plurality of second film removing subunits 1312 are arranged in the first direction D₁Are arranged at intervals, and the first film removing subunit 1311 and the second film removing subunit 1312 are arranged in a second direction D₂Are alternately arranged, wherein the first direction D₁And the second direction D₂Are perpendicular to each other.

In particular, the first direction D₁And the second direction D₂As indicated by the arrows in fig. 3. The pattern shown in fig. 3 is the design pattern of the film removing unit 131 in this embodiment, and the corresponding film layer 12 is removed in the annular closed area of the first film removing subunit 1311 and the second film removing subunit 1312.

In this embodiment, the first film removing subunit 1311 and the second film removing subunit 1312 are square in shape, in other possible embodiments, the first film removing subunit 1311 and the second film removing subunit 1312 may be other shapes, and the shapes of the first film removing subunit 1311 and the second film removing subunit 1312 may be the same or different, which is not limited in this application.

In this embodiment, the first film removing subunit 1311 and the second film removing subunit 1312 have different outer peripheral edge lengths.

Specifically, the edge of the first membrane removing subunit 1311 corresponding to the second membrane removing subunit 1312 refers to the annular outer edge of the first membrane removing subunit 1311 compared with the annular outer edge of the second membrane removing subunit 1312, or the annular inner edge of the first membrane removing subunit 1311 compared with the annular inner edge of the second membrane removing subunit 1312. When the corresponding outer peripheral lengths of the first membrane removing subunit 1311 and the second membrane removing subunit 1312 are different, the annular areas of the first membrane removing subunit 1311 and the second membrane removing subunit 1312 are also different. It can be understood that the frequency of the passing electromagnetic wave signal is related to the annular area of the film removing unit 131, and the larger the annular area of the film removing unit 131 is, the lower the frequency of the passing electromagnetic wave signal is; vice versa, the smaller the annular area of the membrane 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 removing subunit 1311 to have different peripheral lengths corresponding to the second membrane removing subunit 1312, it is possible to achieve a higher transmittance for the multi-band electromagnetic wave signal or a wider communication bandwidth for the electromagnetic wave signal.

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

Specifically, the film layer 12 is subjected to film removal by the design pattern of the film removal unit 131, so that the area ratio of the film removal unit 131 to the film removal region 13 is less than or equal to 5%. As can be appreciated, the smaller the area ratio of the film removing unit 131 to the film removing region 13, the more continuous and aesthetic the overall appearance of the film coating panel assembly 1 is.

In one possible embodiment, please refer to fig. 4, in which fig. 4 is a schematic diagram of a pattern of a film removing unit according to an embodiment of the present disclosure. The second film removing subunits 1312 are arranged at intervals in the area surrounded by the first film removing subunits 1311.

Specifically, in this embodiment, the outer perimeter of the edge of a single first membrane removing subunit 1311 is longer than the outer perimeter of the edge of the corresponding second membrane removing subunit 1312, so that the portion of the transparent plate 11 corresponding to the first membrane removing subunit 1311 is used for passing electromagnetic wave signals in a lower frequency band, and the portion of the transparent plate 11 corresponding to the second membrane removing subunit 1312 is used for passing electromagnetic wave signals in a higher frequency band.

In this embodiment, the periphery of the single second film removing subunit 1312 and the periphery of the first film removing subunit 1311 are at least partially overlapped. Wherein the overlapped part accounts for the sum of the side lengths of the second film subunits 1312 and is between 30 and 50 percent, and preferably 40 percent.

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

Specifically, referring to FIG. 5, FIG. 5 is a schematic view of attenuation performance of a membrane plate assembly according to an embodiment of the present disclosure. As shown in FIG. 5, the abscissa represents the frequency band of the electromagnetic wave signal passing through the coating plate assembly 1, and the ordinate represents the attenuation of the electromagnetic wave signal after passing. As can be seen from the results shown in fig. 5, the pattern design of the film removing unit 131 according to this embodiment can make the electromagnetic wave signal transmission performance of the film-removed film of the film coating plate assembly 1 substantially equal to that of the glass without the film layer 12 at 2.4GHz and 5.8 GHz.

In one possible embodiment, please refer to fig. 6, in which fig. 6 is a schematic diagram of a film removing unit pattern according to another embodiment of the present disclosure. The first film removing subunit 1311 includes a first film removing portion 131a and a plurality of second film removing portions 131b extending from the first film removing portion 131a, the first film removing portion 131a is disposed in a gap between the plurality of second film removing subunits 1312 and is respectively connected to the plurality of second film removing subunits 1312, and the plurality of second film removing portions 131b are respectively disposed to overlap at least a portion of a periphery of the corresponding second film removing subunits 1312.

Specifically, the first film removing portion 131a is inscribed in the plurality of second film removing sub-units 1312, that is, the first film removing portion 131a and the plurality of second film removing sub-units 1312 are not overlapped, and each of the second film removing portions 131b of the first film removing portion 131a is at least partially overlapped with the corresponding peripheral edge of the second film removing sub-unit 1312.

For better observing the design patterns of the first film removing subunit 1311 and the second film removing subunit 1312 in this embodiment, please refer to fig. 7 together, and fig. 7 is a schematic diagram of the patterns of the first film removing subunit and the second film removing subunit provided in an embodiment of the present application. Specifically, as shown in fig. 7, the first film removing subunits 1311 are distributed in a shape of a Chinese character jing as a whole, and the second film removing subunits 1312 form a plurality of squares arranged at intervals. The first film removing part 131a is a small square in the middle of a Chinese character jing, and the second film removing part 131b is formed by extending the sides of the small square of the first film removing part 131 a. In this embodiment, the adjacent and vertical second film removing portions 131b are overlapped with the adjacent two sides of the corresponding one of the second film removing sub-units 1312.

It should be noted that each of the second film removing portions 131b is formed by extending the respective sides of the first film removing portions 131a in opposite directions, and the extending length and the extending width of each of the second film removing portions 131b may be different. In other possible embodiments, the shape of the first film removing subunit 1311 and the second film removing subunit 1312 is not limited by this application as long as the at least partial overlapping arrangement of the first film removing subunit 1311 and the second film removing subunit 1312 is not affected.

In this embodiment, as shown in fig. 6, the transparent plate 11 corresponding to the second film removing subunit 1312 is used for passing electromagnetic wave signals of higher frequency band, while the transparent plate 11 corresponding to the first film removing subunit 1311 is used for passing electromagnetic wave signals of lower frequency band, that is, the portion where the second film removing part 131b and the second film removing subunit 1312 are overlapped can simultaneously pass electromagnetic wave signals of higher and lower frequency band.

It should be added that, compared with fig. 4, when the film layer 12 of the present embodiment is used for the heat and/or electricity conducting function, since the outer periphery of the film removing unit 131 is not closed, the film layer 12 at the inner periphery of the film removing unit 131 can be communicated with the film layer 12 at the outer periphery of the film removing unit 131, and the heat and/or electricity conducting property of the entire film layer 12 is better.

Specifically, referring to FIG. 8 in conjunction, FIG. 8 is a schematic illustration of attenuation performance of a membrane panel assembly according to another embodiment of the present disclosure. As shown in fig. 8, the abscissa represents the frequency band of the electromagnetic wave signal passing through the coating plate assembly 1, and the ordinate represents the attenuation of the electromagnetic wave signal after passing. As can be seen from the results shown in fig. 8, the pattern design of the film removing unit 131 according to this embodiment enables the film coating plate assembly 1 to satisfy the communication function of the mobile 5G dual-band (2.6GHz, 4.9GHz) after removing the film in this way. The attenuation of 2515MHz-2675MHz and 4800MHz-4900MHz relative to the glass without the film layer 12 is less than 5dB, thereby meeting the transparent requirement of the coated glass on the vehicle-mounted 5G signal.

In one possible embodiment, referring to fig. 4 again, the gaps between the second film removing subunits 1312 are W₁The distance between one side of the first membrane removing subunit 1311 and the side corresponding to the membrane removing unit 131 is W₂And satisfy W₁＝K*W₂Wherein the K value is between 1.5 and 2.5.

Specifically, when W is satisfied₁＝K*W₂Then, the resonance performance of the portion of the transparent plate 11 corresponding to the first film removing subunit 1311 and the portion of the transparent plate 11 corresponding to the second film removing subunit 1312 is optimal. The resonance means that when the frequency bands of the two electromagnetic wave signals are the same or close to each other and the distance is suitable, the two electromagnetic wave signals will resonate, so that the radiation intensity of the electromagnetic wave signals is stronger. In the present embodiment, K is preferably 2.

It can be understood that when W₁≠K*W₂When the electromagnetic wave signals of the lower frequency band are resonated, the transparent plate 11 corresponding to the first film removing subunit 1311 will resonate, and the transparent plate 11 corresponding to the second film removing subunit 1312 will resonate the electromagnetic wave signals of the higher frequency band, so as to achieve the resonant performance of the electromagnetic wave signals of the high and low frequencies.

In one possible embodiment, referring to fig. 4 and 6 again, when the membrane removing unit 131 is a square with an outer edge length ranging from 4mm to 20mm, the K value is between 1.8 and 2.2.

In this embodiment, it is preferable that the membrane-removing unit 131 has a length of 12mm on the outer side and the first membrane-removing subunit 1311 has a length of L₁A square with an outer edge length of 11.6mm, and L is the second membrane removing subunit 1312₂A square with an outer side of 5.4 mm.

Specifically, the length of the side other than D of the membrane unit 131, and the length of L of the first membrane-removing subunit 1311₁Outer side length and L of the second non-film subunit 1312₂The outer side lengths are shown in fig. 4 and 6. It will be appreciated that the above values are one application of the laser large area film removal scheme to mass production with a lower film removal area ratio. In other possible embodiments, the length of the side other than D of the membrane unit 131, L of the first membrane sub-unit 1311₁Outer side length and L of the second non-film subunit 1312₂The outer edge length may also be other values, which the present application does not limit.

In one possible embodiment, W₁In the range of 0.1mm to 4mm, W₂Is in the range of 0.05mm to 2 mm.

Preferably, W in the present embodiment₁Is 0.8mm, W₂Is 0.4mm, is the L of the first membrane removal subunit 1311 according to the above except for the D outside edge length of the membrane unit 131₁Outer side length and L of the second non-film subunit 1312₂And calculating the optimal value of the outer side length. L of the first membrane removing subunit 1311 when the D outer side of the membrane removing unit 131 is long₁Outer side length and L of the second non-film subunit 1312₂Outer edgeAt long change, W₁And W₂The numerical values of (c) may also vary, and the application is not limited in this respect.

In one possible embodiment, please refer to fig. 9, and fig. 9 is a schematic diagram of a film removing unit pattern according to another embodiment of the present disclosure. The projection shape of the film removing unit 131 on the film layer 12 is any one or more of a circle or a polygon.
