[0002] Display panels are used in many fields such as electronics, optics, and new energy. The manufacturing process of display panels involves multiple steps. Some steps require heating the semi-finished display panel, while subsequent steps require the semi-finished display panel (especially the substrate) to be at a suitable temperature.

[0003] In existing processes, the main method for cooling high-temperature display panel semi-finished products is natural room temperature cooling. Specifically, the high-temperature display panel semi-finished product is placed on the platform of a cooling device, and the display panel semi-finished product exchanges heat with the ambient air until the temperature drops to a set value.

[0004] The drawbacks of existing methods include: low cooling efficiency, which reduces production efficiency; different display panel semi-finished products may have different initial temperatures, and the resulting temperatures after cooling for the same amount of time will also be different, making it difficult to control the cooling temperature and affecting the quality of the finished display panel.

[0024] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0029] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] This embodiment discloses a display panel semi-finished product cooling device. The term "display panel semi-finished product" includes any stage before the complete processing of the display panel. The cooling device is used to cool a glass substrate or a glass substrate coated with photoresist after a heating step, allowing the glass substrate or the photoresist-coated glass substrate to cool to a set temperature value as quickly as possible, so that subsequent processing steps can proceed. The specific value of the set temperature is not limited, as long as it ensures that subsequent processing steps are performed at a suitable temperature. This cooling device can be applied, but is not limited to, in display panel track lines (usually referring to coating and developing equipment, also known as TRACK).

[0031] like Figures 1 to 4 As shown, the display panel semi-finished product cooling device includes a mounting frame 1 and a cooling body, with the cooling body mounted on the mounting frame 1. The cooling body has a path for the flow of a heat exchange medium. The heat exchange medium absorbs heat from the substrate or photoresist-coated substrate that has undergone a heating step, thereby cooling the substrate or photoresist-coated substrate with high cooling efficiency. By selecting different heat exchange media, the cooling rate and final temperature of the substrate or photoresist-coated substrate can be accurately controlled, improving product quality and production efficiency, and meeting the requirements of various process conditions. The specific type of heat exchange medium is not limited; any material that can cool the substrate (or photoresist-coated substrate) through heat exchange and can flow within the cooling body in existing technologies is acceptable.

[0032] The specific structure of the cooling body is not limited. In this embodiment, the cooling body includes a shell 2 and a heat exchange tube 3. The interior of the heat exchange tube 3 forms a path for the flow of the heat exchange medium. The ends of the heat exchange tube 3 are provided with medium inlet and outlet 31. The heat exchange medium can enter or exit the heat exchange tube 3 through the medium inlet and outlet 31. The heat exchange medium exchanges heat with the substrate (or the substrate coated with photoresist) through the heat exchange tube 3, so that the substrate (or the substrate coated with photoresist) is cooled down quickly, thereby meeting the existing process conditions.

[0033] Based on the above structure, the display panel semi-finished product cooling device also includes a distribution block 4. The cooling body includes at least two heat exchange tubes 3, and each distribution block 4 is connected to the medium inlet and outlet 31 of at least two heat exchange tubes 3. The heat exchange medium enters the medium inlet and outlet 31 evenly or in a set proportion through the distribution block 4, improving the heat dissipation uniformity or making the heat dissipation efficiency at a specified location higher. It can adapt to various personalized requirements, has a wide range of applications, and is more convenient to use.

[0034] The specific shape of the shell 2 is not limited, as long as it can support the heat exchange tubes 3. In this embodiment, the shell 2 is a flat box-shaped body made of aluminum plate, which facilitates the arrangement of multiple heat exchange tubes 3 in a single layer. The plane of the shell 2 is parallel to the plane of the mounting bracket 1, and the shell 2 can be adjusted synchronously by adjusting the tilt angle of the mounting bracket 1, making it more convenient to use.

[0035] To improve heat dissipation efficiency, the cooling body includes at least three heat exchange tubes 3. The substrate to be cooled (or the substrate coated with photoresist) can come into contact with more heat exchange tubes 3, thereby exchanging heat with more heat exchange medium, resulting in high heat dissipation efficiency.

[0036] The temperature on the substrate (or substrate coated with photoresist) to be cooled may be uneven. Accordingly, areas with higher temperatures need to be in contact with more heat exchange tubes 3, while areas with lower temperatures can meet the cooling requirements with fewer heat exchange tubes 3. To address this, the heat exchange tubes 3 can be translated in a direction perpendicular to the axis to adjust the distance between two adjacent heat exchange tubes 3. That is, more heat exchange tubes 3 can be arranged in a local area of ​​the cooling body, thereby improving the heat dissipation efficiency of that area.

[0037] The cooling unit has two main structures: In one structure, the heat exchange tube 3 is set in the cavity enclosed by the shell 2. To improve heat exchange efficiency, the outer wall of the heat exchange tube 3 is in contact with the shell 2, or the heat exchange tube 3 is integrally formed with the shell 2, so that the heat exchange medium is closer to the substrate to be dissipated (or the substrate coated with photoresist), resulting in a better user experience.

[0038] In another configuration, the heat exchange tubes 3 are positioned on the outside of the housing 2. All heat exchange tubes 3 have a uniform outer surface height, and the semi-finished display panel to be cooled is placed on the outer surface of the heat exchange tubes 3. This reduces processing difficulty without affecting normal heat exchange and facilitates the replacement of individual heat exchange tubes 3.

[0039] Based on the above structure, the mounting bracket 1 includes support rods 11 for connecting the cooling body, and the cooling body is fixedly connected to the support rods 11. In this embodiment, multiple parallel support rods 11 are fixedly connected to the cooling body, making the structure of the cooling body more stable and safer to use.

[0040] To further improve heat dissipation efficiency, the support rod 11 is made of a hollow metal tube with a rectangular or square cross-section. When low-temperature air passes through the cavity in the support rod 11, it can exchange heat with the support rod 11, causing the air to heat up and the support rod 11 to cool down. After cooling, the support rod 11 can exchange heat with the cooling body, causing the cooling body to cool down, thereby improving the heat dissipation efficiency of the substrate (or substrate coated with photoresist) placed on the cooling body.

[0041] When the mounting bracket 1 includes at least two support rods 11, a reinforcing rib 12 is connected between adjacent support rods 11 to improve structural stability. One reinforcing rib 12 and the two support rods 11 form an I-shaped structure, resulting in higher strength and stability. The reinforcing rib 12 and the support rods 11 are on the same plane, ensuring that they do not affect the fixed connection of the cooling body to the support rods 11, thus making the installation structure of the cooling body more stable.
