Description
Technical Field
The utility model relates to the technical field of photovoltaic glass, in particular to a coating device for preparing high-flatness ultrathin coated glass.
Background
The prior anti-reflection glass generally adopts a traditional coating process, and the anti-reflection film coating is directly carried out on the surface of the glass substrate in a roller coating mode. Because the glass substrate is placed on the surface of the conveying platform and conveyed to the roller coating position for roller coating of the antireflection liquid, and a height difference (the height difference is the thickness of glass) exists between the glass substrate and the surface of the conveying platform, and meanwhile, the distance between the coating roller and the surface of the conveying platform is required to be smaller than the thickness of the glass substrate (namely smaller than the height difference) in order to ensure the coating effect of the glass substrate, so that the coating roller has a certain pressure on the surface of the glass substrate. Therefore, the method of directly using the coating roller for roll coating film coating can lead to that the head and the tail of the glass substrate are subjected to larger pressure by the coating roller due to the height difference when the glass to be coated just contacts with the coating roller and is separated from the coating roller, thereby leading to uneven film coating layers at the head and the tail of the glass substrate. Therefore, the problem of uneven film coating of the whole glass can be caused, the film thickness of a glass product can not be ensured to be uniform, and the flatness of the film surface after film coating is poor; the problems of uneven coating and poor surface smoothness are that serious warpage of the head and tail parts of coated glass easily occurs in the subsequent sintering and tempering processes of the coated glass, and the product quality is affected.
Disclosure of Invention
The utility model aims at: aiming at the problems that the traditional direct roller coating film coating mode is easy to cause uneven film coating and influence the quality of finished products, the utility model designs and develops a film coating device for preparing high-flatness ultrathin film coated glass, and the film coating device is used as an auxiliary tool, so that ultrathin AR glass with high flatness and even film coating can be obtained.
The utility model is realized by the following technical scheme:
a coating device for preparing ultra-thin coated glass of high roughness, its characterized in that, coating device include: the device comprises a carrier and a coating groove arranged in the carrier; a plurality of air holes are also formed in the coating tank;
when coating film: the coating groove is used for placing the ultrathin glass, and the depth of the coating groove is consistent with the thickness of the ultrathin glass.
Specifically, the ultra-thin glass is coated by adopting the coating device as an auxiliary tool in the roll coating and coating process; when the coating roller just begins to contact with the carrier, the coating roller can not be directly pressed on the ultrathin glass, the coating roller firstly moves upwards for a certain distance on the carrier and then can be contacted with the surface of the ultrathin glass, at the moment, the pressure transmitted to the carrier and the ultrathin glass by the coating roller is uniform, the uniformity and the high flatness of a film surface can be ensured, and the situation that the edge of the coating is warped in the subsequent sintering and toughening processes of the coating can not be generated. Similarly, when the coating roller is coated on the tail end of the ultrathin glass, the coating roller needs to continuously move on the carrier for a certain distance to be separated from the carrier, so that uneven coating of the tail end of the ultrathin glass can not be caused.
When the coating roller formally rolls the surface of the ultrathin glass, the upper surface of the ultrathin glass can form a plane with the surface of the carrier, namely, the coating films at the head end and the tail end are left on the carrier when the coating roller rolls, but not directly coat the progress of the ultrathin glass. Thus, the problem that the thickness of the film coating layers at the two ends of the glass is inconsistent with that of the film coating layer at the middle section due to the height difference between the glass and the conveying platform is avoided.
The main reasons for the difference of the thickness of the film coating layers are as follows: (1) The coating roller just contacts the ultrathin glass, so that the film layer of the ultrathin glass just started to be coated is thicker due to the problem of the height difference between the ultrathin glass and the conveying platform; (2) When the coating roller and the ultrathin glass are separated, the contact area of the coating roller and the ultrathin glass is gradually reduced to be completely separated, and the pressure of the coating roller to the glass is gradually increased in the process, so that the tail end coating film of the ultrathin glass is uneven compared with the middle part of the tail end coating film. The coating device designed by the application ensures that when the coating roller is used for formally coating the surface of the ultrathin glass, the coating roller can firstly roll-coat the surface of the carrier, and when the coating roller roll-coats the ultrathin glass, the surface of the carrier and the surface of the ultrathin glass are in a plane without height difference, so that the uniform rolling effect can be ensured; likewise, when the roller is coated to the tail end of the ultrathin glass, the coating roller and the ultrathin glass can be smoothly separated, the coating effect is good, the coating surface is smooth and uniform, and the warping problem is not easy to occur in the subsequent sintering and tempering processes.
Further, a coating device for preparing high-flatness ultrathin coated glass: the carrier is made of silica gel.
Preferably, the silica gel material that this application adopted is difficult fish tail glass and easy washing after using.
Further, a coating device for preparing high-flatness ultrathin coated glass: the length of the coating groove is 1.0-3.0 mm longer than that of the ultrathin glass; the width of the coating groove is 1.0-3.0 mm larger than that of the ultrathin glass.
The size of the carrier is larger than that of the coating tank.
Further, a coating device for preparing high-flatness ultrathin coated glass: the carrier is provided with a coating head end and a coating tail end along the length direction; the coating groove is arranged in the middle of the carrier along the length direction of the carrier.
Further, a coating device for preparing high-flatness ultrathin coated glass: the distance between the head end and the tail end of the coating groove and the head end and the tail end of the coating film is 50-200 mm respectively; the distance from the two sides of the coating groove to the two sides of the carrier is 2-10 mm.
Further, a coating device for preparing high-flatness ultrathin coated glass: the air holes are densely distributed at the bottom of the coating tank; the air holes are used for being communicated with an external air pipe and blowing the ultrathin glass out of the coating groove after coating.
Specifically, be provided with a plurality of gas pockets that can be used to the outside tracheal of intercommunication in this application coating film groove's bottom, can make the ultra-thin glass in the coating film groove suspend through blowing after the coating film is accomplished and take out after being convenient for the coating film is accomplished, can take out coated glass through this kind of air supporting mode with the help of external device, can further avoid the membrane face fish tail, guarantee product quality.
