Description

Technical Field

[0001] This utility model relates to the field of optoelectronic thin film technology, and in particular to a drying device for optoelectronic thin film processing. Background Technology

[0002] Drying is a crucial step in the processing of optoelectronic thin films, used to remove moisture and solvents from the film to ensure its quality and performance. However, existing drying equipment suffers from uneven moisture evaporation during the drying process, and it is difficult to control the drying temperature, resulting in residual moisture in local areas, which in turn forms watermarks and affects the optical performance and appearance quality of the film. Utility Model Content

[0003] The purpose of this invention is to provide a drying device for photoelectric thin film processing, thereby solving the aforementioned problems in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A drying device for photoelectric thin film processing includes a box and a roller. The roller is disposed between the front and rear ends of opposite sides of the inner cavity of the box. The box is provided with a drying mechanism for drying the thin film body.

[0006] The drying mechanism includes a housing and a first fan disposed at the upper and lower ends of the box body. A heating rod is disposed between the upper and lower ends of the inner cavity of the housing. A first air duct is connected between the input end of the first fan and the housing. A second air duct extending into the inner cavity of the box body is disposed at the output end of the first fan. The mechanism also includes an electric push rod disposed on the upper and lower sides of the inner cavity of the box body. An air box is horizontally disposed at the output end of the electric push rod. A flexible hose is connected between the air box and the second air duct. Multiple air outlet pipes are arranged in an array on the opposite side of the two air boxes. An air inlet is opened at one end of the housing. A dustproof screen is disposed inside the air inlet. The mechanism also includes a temperature detector disposed on one side of the inner cavity of the box body.

[0007] The beneficial effects of this utility model are as follows: When the first fan is started, air is drawn in through the air inlet and prevented from entering by dust under the action of the dustproof net. The air is heated by the heating rod and enters the hose through the first and second air ducts, then enters the air box through the hose, and is sprayed out through the air outlet to dry the film body. The air drying of the film by blowing air through the array of air outlets improves the uniformity of heating of the film, further ensures uniform evaporation of moisture, and avoids watermarks caused by moisture residue in some areas. Moreover, when the temperature detector detects that the temperature inside the box is low, the temperature of the heating rod is controlled, and the position of the air box is adjusted by the electric push rod so that the air outlet is closer to the film body, which improves the drying effect and further avoids watermarks caused by moisture residue.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes partitions, which are staggered on opposite sides of the inner cavity of the housing.

[0010] Furthermore, a second fan is provided on each of the two opposing sides of the housing. The input end of the second fan is connected to the housing via a third duct, and the output end of the second fan is connected to the housing via a fourth duct.

[0011] The further beneficial effects of adopting the above are: by starting the second fan, the second fan sends the air in the box to the shell through the third and fourth air ducts for reheating, thereby increasing the heat of the air, facilitating recycling and reducing heat loss.

[0012] Furthermore, each of the four corners of the bottom of the box is provided with a vertically downward support leg.

[0013] Furthermore, ventilation holes are provided on both the left and right sides of the box, and filters are installed inside the ventilation holes.

[0014] Furthermore, a controller is provided on the front of the housing, and the controller is electrically connected to the heating rod, the first fan, the electric push rod, the second fan, and the temperature detector. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, a drying device for photoelectric thin film processing includes a housing 1 and a roller 6. The roller 6 is disposed between the front and rear ends of opposite sides of the inner cavity of the housing 1. The housing 1 is provided with a drying mechanism 2 for drying the thin film body 5.

[0022] The drying mechanism 2 includes a housing 21 disposed at the upper and lower ends of the box body 1 and a first fan 25. A heating rod 22 is disposed between the upper and lower ends of the inner cavity of the housing 21. A first air duct 24 is connected between the input end of the first fan 25 and the housing 21. A second air duct 26 extending into the inner cavity of the box body 1 is disposed at the output end of the first fan 25. The mechanism also includes an electric push rod 210 disposed on the upper and lower sides of the inner cavity of the box body 1. A wind box 28 is horizontally disposed at the output end of the electric push rod 210. A flexible hose 27 is connected between the wind box 28 and the second air duct 26. Multiple air outlet pipes 29 are arranged on the opposite side of the two wind boxes 28. An air inlet 215 is opened at one end of the housing 21. A dustproof net 216 is disposed inside the air inlet 215. The mechanism also includes a temperature detector 214 disposed on one side of the inner cavity of the box body 1.

[0023] The first fan 25 is started, drawing air in through the air inlet 215. Dust is prevented from entering by the dust filter 216. The air is heated by the heating rod 22 and enters the hose 27 through the first air duct 24 and the second air duct 26. From there, it enters the air box 28 and is ejected through the air outlet 29, drying the film body 5. The array of air outlets 29 dries the film, improving the uniformity of heating and ensuring even moisture evaporation, preventing watermarks from forming in localized areas. Furthermore, when the temperature detector 214 detects a low internal temperature in the chamber 1, it controls the temperature of the heating rod 22 and adjusts the position of the air box 28 via the electric push rod 210, bringing the air outlet 29 closer to the film body 5 to improve drying efficiency and further prevent watermarks from forming.

The input end of the second fan 212 is connected to the housing 1 via a third air duct 211, and the output end of the second fan 212 is connected to the housing 21 via a fourth air duct 213. By starting the second fan 212, the second fan 212 sends the air in the housing 1 to the housing 21 through the third air duct 211 and the fourth air duct 213 for reheating, thereby increasing the heat of the air, facilitating recycling and reducing heat loss.
