Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a thin-film battery printing device. Background Art

[0002] As the name suggests, thin-film batteries are solar cells made from a thin film. They use very little silicon and are more likely to reduce costs. The power generation principle of thin-film batteries is similar to that of crystalline silicon. When sunlight shines on the battery, the battery absorbs light energy to generate photogenerated electron-hole pairs. Under the action of the built-in electric field of the battery, the photogenerated electrons and holes are separated, the holes drift to the P side, and the electrons drift to the N side, forming a photogenerated electromotive force. When the external circuit is connected, current is generated.

[0003] Thin-film batteries are batteries that are made of two or more different materials, at least one of which is in the form of a thin film. A thin-film battery consists of three main parts: a positive electrode, a negative electrode, and a proton exchange membrane between the two. The proton exchange membrane mainly plays a role in Ion conductor It acts as a barrier, isolating the anode and cathode while allowing protons to pass through.

[0004] Existing thin-film battery printing devices generally print by means of a printing roller or spraying. After printing, printing can be completed by drying the slurry on the film. For example, Chinese patent application number CN202223565552.6 discloses a thin-film battery printing device, including a base, a support column, a transmission platform, a bracket, a printing mechanism, a cleaning mechanism, and an air-drying mechanism. The base is fixedly connected to a support column, the support column is fixedly connected to a transmission platform, the transmission platform is fixedly connected to a bracket, the bracket is fixedly connected to the base, a printing mechanism is arranged inside the bracket, a cleaning mechanism is arranged on the printing mechanism, and an air-drying mechanism is arranged on the bracket.

[0005] Since the wind blown out by the air-drying mechanism will directly contact the film after passing through the second ventilation block, and the weight of the film is generally light, the film may shake under the action of the wind, and the blown wind may contact other structures and then be redirected to the film. If the wind is directed back to the film from the side of the film, it may cause the film to be blown up, thereby causing the film to warp, which is not convenient for subsequent printing of the film.

[0029] During operation, the motor drives the wind wheel to rotate, sucking the water vapor emitted by the slurry from the air inlet 10, and then blowing the water vapor away from the air outlet, so as to keep the water vapor away from the slurry and prevent the water vapor from re-entering the slurry.
