Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic substrate drying technology, and in particular relates to a photovoltaic printing substrate drying device. Background Technology

[0002] In the photovoltaic industry, the drying process of photovoltaic substrates is a crucial step. With the rapid development of the photovoltaic industry, the requirements for the production efficiency and quality of photovoltaic substrates are constantly increasing. After cleaning and other processes, water stains will remain on the surface of the photovoltaic substrates. If these water stains are not removed in a timely and effective manner, they will affect the quality of subsequent production processes, such as coating and printing, thereby reducing the photoelectric conversion efficiency and lifespan of photovoltaic products.

[0003] Traditional drying methods often have many drawbacks. During the drying process, some common drying equipment lacks effective protective measures, and water stains can easily splash into the surrounding environment. This not only causes dampness in the work area, affecting the normal operation and service life of the equipment, but may also cause water stains to contaminate other treated parts or materials, increasing the defect rate of products. Utility Model Content

[0004] This invention addresses the problem in existing technologies where, during the drying process, the lack of effective protective measures allows water to easily splash into the surrounding environment. This not only causes dampness in the work area, affecting the normal operation and lifespan of equipment, but may also lead to water contamination of other treated components or materials, increasing the product defect rate. The following technical solution is proposed:

[0005] A photovoltaic printing substrate drying device includes: a platform, a dust extraction horn fixedly connected to the bottom end of the platform, an air blowing device installed on the outer surface of the platform, an air inlet fixedly connected to the bottom end of the air blowing device, a heating rod installed inside the air blowing device, an air blowing port opened at the connection between the platform and the air blowing device, and a screw rotatably connected inside the platform, with a rubber pad connected to the outer surface of the screw by threads.

[0006] As a preferred embodiment of the above technical solution, the number of the air blowing devices is set to four, and they are all symmetrically installed on the outer surface of the stage.

[0007] As a preferred embodiment of the above technical solution, limit blocks are symmetrically fixedly installed on the inner wall of the stage at positions corresponding to both sides of the rubber pad.

[0008] As a preferred embodiment of the above technical solution, the inner wall of the stage is symmetrically fixed with support plates, and the surfaces of the four support plates are provided with through holes.

[0009] As a preferred embodiment of the above technical solution, the top of the four support plates is provided with the same printing substrate.

[0010] As a preferred embodiment of the above technical solution, the dust extraction nozzle is located directly below the printing substrate, and the size of the dust extraction nozzle is larger than the size of the printing substrate.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) The heating rod inside the blowing device can make the blown gas hot, which can quickly increase the surface temperature of the photovoltaic substrate, accelerate the evaporation of water stains, significantly shorten the drying time, improve production efficiency, and meet the needs of large-scale production in the photovoltaic industry.

[0013] (2) The dust extraction horn at the bottom of the photovoltaic carrier is larger than the photovoltaic carrier, which can effectively collect water splashes caused by air blowing. At the same time, the air blowing device around the photovoltaic carrier blows air in a directional manner to prevent water from splashing into the surrounding environment, keeping the working area dry and clean, and reducing pollution to other equipment and products.

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example 1

[0020] This utility model provides a photovoltaic printing substrate drying device, such as... Figures 1 to 3As shown, it includes a platform 1, a dust extraction horn 2 fixedly connected to the bottom of the platform 1, an air blowing device 4 installed on the outer surface of the platform 1, a fan installed inside the air blowing device 4, an air inlet 5 fixedly connected to the bottom of the air blowing device 4, a heating rod 6 installed inside the air blowing device 4, an air blowing port 7 opened at the connection between the platform 1 and the air blowing device 4, a screw 9 rotatably connected inside the platform 1, a rubber pad 10 threadedly connected to the outer surface of the screw 9, support plates 8 symmetrically fixedly installed on the inner wall of the platform 1, each of the four support plates 8 having through holes on its surface, and the same printing carrier 3 placed on the top of the four support plates 8. During operation, the... The printing substrate 3 is placed on top of the support plate 8. Then, the screw 9 is rotated, which drives the rubber pad 10 to move closer to the printing substrate 3 through the threaded connection, thereby clamping and fixing the printing substrate 3. The air blowing device 4 is started, and the heating rod 6 inside the air blowing device 4 heats the gas. The heated gas is blown evenly onto the lower surface of the printing substrate 3, causing the water stains to vaporize quickly. At the same time, the dust extraction nozzle 2 continues to work, removing water stains that may be splashed by the air blowing and dust adhering to the surface of the printing substrate 3, keeping the working area clean and dry, and avoiding adverse effects of water stains and dust on the surrounding environment and subsequent photovoltaic production processes.

[0021] like Figure 1 and Figure 2 As shown, there are four air blowing devices 4, all symmetrically installed on the outer surface of the stage 1. The air blowing devices 4 around the perimeter can make the hot air act evenly on the lower surface of the printing substrate 3, avoiding local overheating or uneven drying, ensuring that the overall drying effect of the printing substrate 3 is consistent, which is conducive to the smooth progress of subsequent high-precision processes such as coating and printing.

[0022] like Figure 2 and Figure 3 As shown, limit blocks 11 are symmetrically fixedly installed on the inner wall of the stage 1 at the positions corresponding to the two sides of the rubber pad 10. Sliding grooves are provided on the two sides of the rubber pad 10 at the outer positions corresponding to the limit blocks 11, so that when the screw 9 is rotated, the rubber pad 10 is limited by the limit blocks 11 and cannot rotate, thereby allowing the rubber pad 10 to slide towards the printing carrier plate 3, thereby clamping and fixing the printing carrier plate 3 and preventing the printing carrier plate 3 from shifting when the air blowing device 4 blows air.

[0023] like Figure 1 and Figure 2 As shown, the dust extraction nozzle 2 is located directly below the printing carrier plate 3 and the size of the dust extraction nozzle 2 is larger than that of the printing carrier plate 3, effectively collecting water stains splashed by the air blowing. At the same time, the air blowing device 4 around the printing carrier plate 3 blows air in a directional manner to prevent water stains from splashing into the surrounding environment, keeping the working area dry and clean, and reducing contamination to other equipment and products.

[0024] Working principle: In use, the printing carrier plate 3 is placed on top of the support plate 8. Then, the screw 9 is rotated, and the limiting block 11 engages with the sliding groove of the rubber pad 10, preventing the rubber pad 10 from rotating. This allows the rubber pad 10 to slide closer to the printing carrier plate 3, thereby clamping and fixing the printing carrier plate 3 and preventing it from shifting when the air blowing device 4 blows air. Then, the air blowing device 4 is activated, so that the air drawn in through the air inlet 5 is heated by the heating rod 6 and then blown out. The air blowing device 4 around the perimeter ensures that the hot air is evenly distributed. The airflow is evenly applied to the lower surface of the printing substrate 3 to avoid localized overheating or uneven drying, ensuring a consistent drying effect across the entire substrate 3 and allowing surface water to evaporate quickly. Simultaneously, the dust extraction nozzle 2, connected to a vacuum cleaner, is activated to remove any water splashes and dust already adhering to the surface of the printing substrate 3. This eliminates the need for additional dust removal processes, simplifying the production process, maintaining a clean and dry working environment, and effectively preventing dust from negatively impacting subsequent photovoltaic processes, thus improving product quality. The above embodiments are merely illustrative of the technical solution of this utility model and are not intended to limit it.
