Problems solved by technology

[0003] At present, the coating of photovoltaic glass mainly adopts roller coating process, while imported equipment is usually used in the domestic market, which is costly and inconvenient for after-sales service. However, some similar domestic equipment has structural defects, and the coating quality is not high and the accuracy cannot be achieved. The level of imported equipment, the present invention provides a film coating machine suitable for anti-reflection and anti-reflection of photovoltaic glass on the basis of adopting the roller coating process, which meets the requirements of stable coating quality and high light transmittance

Embodiment 1

[0062] Embodiment 1, the front belt conveying device 1 is mainly used to pick up the glass sent from the front, and smoothly send the glass into the main machine 2 of the coating machine for roller coating and coating treatment; all the coating processes of the glass plate are completed in the main machine. , and control the thickness and precision of the film layer; after the coating process is completed, the glass is sent to the rear belt conveyor 3 to be sent to the next process, and the coating process is completed. All coating processes are placed in a single mold chamber.

Embodiment 2

[0063] Embodiment 2, the front belt conveyor 1 includes the front belt conveyor 1 includes a first support frame 11, a second belt 12, a second motor 14, a second driving roller and a second driven roller frame 25, a seamless belt, The driving roller and the follower roller, the second belt 12 is driven by the second motor 14 installed at one end of the second driving roller, the second driving roller is a rubber roller, the material is nitrile rubber, the follower roller is a steel roller, and the second driving roller is a steel roller. Roller speed defaults to coating belt speed

[0064] The main machine 2 of the coating machine includes: a nip roller 21 , a coating roller 22 , a de-texture roller 23 , a quantitative roller 24 , a frame 25 , a first belt 26 and a middle belt conveying device 27 . The main function of the nip roller 21 is to ensure that the glass remains stable during the feeding process. Before the front edge of the glass reaches the nip roller 21, the nip ...

Embodiment 3

[0069] In the third embodiment, the lifting and lowering of the pressing roller 21 is performed up and down by the first lifting device through the first lead screw elevator, and at the same time, it can also be manually adjusted up and down through the first hand wheel 212; the first lifting device can be a lead screw lifting device. Or cylinder lifting device;

[0070] The lifting and lowering of the coating roller 22 and the quantitative roller 24 is performed up and down by the second lifting device through the second screw lifter 223 , and can also be manually adjusted up and down by the second hand wheel 222 .

[0071] In addition, the structure of the rear belt conveyor 3 is the same as that of the front belt conveyor 1 .

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a film coating machine for anti-reflection and anti-reflection of photovoltaic glass. Background technique [0002] The light transmittance of ordinary ultra-clear embossed glass is only about 91.5%. At present, one of the more popular methods in the industry is to coat a layer of anti-reflection film on the sunlight incident surface (cover glass) of solar packaging glass to improve Light transmittance, increase the output power of battery components and reduce the electricity cost per kilowatt-hour of components. The anti-reflection coating can increase the transmittance by 1.8% to 3.0%, and the output power of crystalline silicon battery components can also be increased by 2% to 4%. [0003] At present, the coating of photovoltaic glass mainly adopts roller coating process, while imported equipment is usually used in the domestic market, which is costly and inconv...
