Description
Technical field:
The present invention relates to coated glass technical field, especially a kind of coated glass with communication window.
Background technique:
Currently, vehicle glass heat-insulating technique passes through one layer of the plating on automobile front windshield increasingly by everybody attention
Or several layers of nano level metal film reflect external heat, realize completely cut off during car steering external heat enter (summer) or
The effect of interior heat losses (winter).Such heat-insulated windshield is also increasingly by big well-established, but on glass
Electromagnetic radiation can be shielded by plating metallic diaphragm, and using for vehicle mounted guidance, communication or radio is caused to be broken down, this kind of to avoid
Problem needs to remove metallic diaphragm in the specific region of front.It can be taken in actual production and place cover board or laser membrane-removing
Mode realizes, such as described in Chinese patent CN201410383371.2 and CN200480027849.2.Wherein, laser removes
Film is specifically using laser burn metallic diaphragm and then to remove part metals film layer, is formed on metallic diaphragm latticed
Coating-free area, electromagnetic radiation can emit and receive via latticed coating-free area, since laser membrane-removing has automation journey
The advantages that degree is high, forms the good concealment of pattern, by major institute, vehicle glass manufacturer extensive utilization.But in actual production
It was found that be easy to appear optics after windshield hot bending shape bad in laser membrane-removing region, and optics is bad before automobile
Keeping off in the production of glass is absolute prohibition.
Conventional laser membrane-removing method, the grid size being formed by grid is identical, during hot bending, due to glass
The bending degree of different zones is different, and the molding heat of grid and the uncoated molding heat of membrane removal line containing metallic diaphragm are poor
It is different excessive, it is serious to will cause Glass optical deformation, lesser extent, it will form shadow when examining optics.
The bad problem of optics, Chinese patent are easy to appear after windshield hot bending shape for laser membrane-removing region
CN201480012776.3, which is proposed, increases external grid line, and external grid line has since the outer edge of inner grid line
The interruption become larger.What the communication window edge that such design of the patent claims can reduce glass generated in hot bending shape
Optical skew, but in actual production, optical skew could be utmostly avoided for how to interrupt, specifically, in
We are difficult to hold disconnected area and spacing, and furthermore the requirement to design personnel and laser membrane-removing equipment is very high, therefore
Seek a kind of convenient for operation, laser scoring scheme simple and easy to get, while light of glass during hot bending can be eliminated well
It is necessary for learning deformation.
