Problems solved by technology
[0002] At present, the online production of coated glass is usually carried out according to the principle of chemical vapor deposition. However, the existing glass online coating method has a single function and can only coat thinner solar control film glass, which cannot achieve a wide range of film thickness. Adjustment, can not adapt to the requirements of large flow reaction gas coating, so the function and quality of the product are limited
[0003] With the increasing use of solar cells, the market for SnO 2 The demand for film conductive glass is increasing, but there is no SnO 2 A technical solution for online coating of film conductive glass, therefore, the manufacture of SnO for solar cells 2 Membrane conductive glass needs to be imported in large quantities, and the cost is high

Embodiment Construction
[0009] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0010] Such as figure 1 As shown, the online coating method of conductive glass in the embodiment of the present invention comprises the following steps: a coating area is set in the annealing kiln 1 of the glass production line; the glass substrate 2 after forming is entered in the annealing kiln 1 and moves forward ( figure 1 The direction shown by the middle arrow A is the moving direction of the glass substrate 2); when the temperature of the glass substrate 2 drops to a temperature suitable for coating, the glass substrate 2 enters the coating area; At the sa...

The invention relates to an on-line film coating method of conductive glass and an on-line film coating device. A film coating area is arranged in an annealing kiln of a glass production line, and a formed glass substrate enters the annealing kiln and moves forwards. When the temperature of the glass substrate is reduced to be suitable for film coating, the glass substrate enters the film coatingarea. Reaction gas is simultaneously input to the film coating area from the downstream of the film coating area in an inclined gas inlet mode, and the forward direction of the reaction gas is opposite to the moving direction of the glass substrate so that the a film layer is deposited on the surface of the glass substrate after the chemical reaction of the reaction gas, and waste gas is pumped outwards from the upstream of the film coating area. By adopting the method and the device, on-line film coating is carried out by utilizing the residual heat after the formed glass enters the annealing kiln, thereby the flow time of coating film for glass is shortened, and energy source consumed by heating necessary for non-on-line film coating is saved. In addition, a gas inlet channel and a gas pumping channel are independent units and can be flexibly and conveniently detached and assembled according to the production requirement, and conductive glass with various film thicknesses and various electric conductivities can be obtained.
Description
technical field [0001] The invention belongs to the field of glass production, and in particular relates to an online coating method and an online coating device for conductive glass (TCO glass, Transparent Conductive Oxide, transparent conductive oxide). Background technique [0002] At present, the online production of coated glass is usually carried out according to the principle of chemical vapor deposition. However, the existing glass online coating method has a single function and can only coat thinner solar control film glass, which cannot achieve a wide range of film thickness. The adjustment cannot meet the requirements of large-flow reaction gas coating, so the function and quality of the product are limited. [0003] With the increasing use of solar cells, the market for SnO 2 The demand for film conductive glass is increasing, but there is no SnO 2 A technical solution for online coating of film conductive glass, therefore, the manufacture of SnO for solar cell...
