Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module production technology, and in particular to a drying device and a photovoltaic module production system. Background Technology

[0002] In the photovoltaic module manufacturing process, especially during autumn and winter, water droplets easily form on the glass surface due to low temperatures. These water droplets form a lubricating layer between the glass and the subsequent adhesive film, significantly reducing the friction between them. This makes the adhesive film prone to slippage or displacement due to insufficient friction, which in turn has a series of negative impacts on subsequent production processes (such as lamination). To overcome these problems, existing technologies remove water droplets by preheating the glass in the factory. However, existing methods for removing water droplets cannot completely solve the problem. Utility Model Content

[0003] Therefore, it is necessary to provide a drying device and a photovoltaic module production system to address the problem that existing methods for removing water droplets cannot completely solve the water droplet problem.

[0013] In one embodiment, the first air supply duct includes a horizontal pipe, an air passage plate, and a vertical pipe. The number of the horizontal pipe and the vertical pipe is at least one. One end of each horizontal pipe is connected to the hot air generating component.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application 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 application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In response to the fact that the existing technology of preheating the glass in the factory beforehand cannot completely solve the water droplet problem, the inventor conducted tests and analysis and found that: after stacking the glass and preheating it in the factory, the temperature of the upper glass layer can usually only be increased, while the temperature of the middle and lower glass layers remains low, thus failing to completely solve the water droplet problem.

[0028] Based on the above problems, the inventors designed and proposed the drying apparatus 10 and photovoltaic module production system according to the following embodiments of this application to solve the above technical problems.

[0029] The photovoltaic module production system includes a glass feeder, a conveying device, and an encapsulated film cutter. The glass feeder and the encapsulated film cutter are arranged alternately, and the conveying device is installed between the glass feeder and the encapsulated film cutter. The glass feeder feeds glass to the conveying device, which then conveys the glass to the encapsulated film cutter.

[0030] It should be noted that the glass feeder can be configured as any of the existing glass feeding structures. The film cutting machine can be configured as any of the existing film cutting structures. The conveying device can be configured as any of the existing glass conveying structures. For example, the conveying device can be a belt conveyor structure.

[0031] like Figure 1As shown, in one embodiment, a glass drying apparatus 10 is provided, including a drying body 100 and a heating structure 200. The drying body 100 has a drying chamber 110 and an inlet 120 and an outlet 130 communicating with the drying chamber 110. The inlet 120, the drying chamber 110, and the outlet 130 are sequentially connected to form a transmission channel for a conveying device to pass through. The heating structure 200 is installed on the drying body 100 and configured to heat the glass to dry it during the process of the conveying device transporting the glass through the transmission channel.

[0032] In the above embodiments, the drying device 10 is installed on the conveying device, allowing the conveying device to pass through the conveying channel. The drying device 10 does not affect the layout or production efficiency of the photovoltaic module production system. During the process of the conveying device transporting the glass through the conveying channel, the heating structure 200 heats the glass, rapidly increasing its temperature to evaporate water droplets on the glass surface. This ensures that the glass surface is free of water droplets during subsequent film lamination and bonding processes, preventing slippage or misalignment between the film and the glass due to insufficient friction, thus improving the production quality and efficiency of the photovoltaic modules.

[0033] The heating structure 200 can remove water droplets from the glass surface by heating the glass through airflow drying, microwave drying, infrared drying, or other drying methods. For example, the heating structure 200 can remove water droplets by blowing hot air onto the glass surface, by directly heating the glass surface with infrared radiation, or by heating the inside of the glass with microwave radiation to raise the glass temperature from the inside out and remove water droplets.

[0034] The positions of the transmission channel and the heating structure 200 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the heating structure 200 can be installed on the top of the drying body 100 by snap-fit, screw-fit, plug-in, or other means.

[0035] like Figure 1 and Figure 2 As shown, the heating structure 200 further includes at least one heating element 211. Each heating element 211 is located within the drying chamber 110 and is configured to heat the glass when the conveying device transports the glass into the drying chamber 110. Thus, when the conveying device transports the glass into the drying chamber 110, the heating element 211 heats the glass, causing water droplets on the glass surface to absorb heat and evaporate, thereby achieving the effect of removing water droplets.

[0036] The number and arrangement of the heating elements 211 can be flexibly adjusted according to actual usage needs.

[0037] like Figure 1 and Figure 2As shown, optionally, the heating element 211 is an infrared lamp, and the heating structure 200 also includes a conduit 212, wires, and a power supply. The power supply is located outside the drying body 100. There is at least one conduit 212 and one wire. Each conduit 212 is inserted into the drying chamber 110. One end of each wire is electrically connected to the power supply, and the other end of each wire passes through the conduit 212 and is electrically connected to the infrared lamp. Thus, the conduit 212 protects the wires, reduces the impact of high-temperature environments on the wires, and improves the reliability of the drying device 10.

[0038] like Figure 1 and Figure 2 As shown, in this specific embodiment, there are four infrared lamps, located at the four corners of the top of the drying chamber 110, and each is electrically connected to a power source via wires. Thus, the four infrared lamps can emit infrared rays towards the glass from different directions, allowing the surface temperature of the glass to rise uniformly, ensuring that all water droplets on the glass surface are completely removed, and improving the reliability of the drying device 10.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, the heating structure 200 includes a hot air generating assembly 220 and an air supply assembly 230. The air supply assembly 230 is connected to the hot air generating assembly 220 and is configured to blow air onto the glass as the conveying device transports the glass through the inlet 120 and / or outlet 130.

[0040] As the conveyor transports the glass through the inlet 120, the air supply assembly 230 blows hot air towards the glass to preheat it, rapidly raising the surface temperature and causing water droplets to absorb heat and evaporate. Subsequently, the conveyor transports the glass into the drying chamber 110, where the heating element 211 continues to heat the glass surface, allowing further evaporation of water droplets. Then, as the conveyor transports the glass out of the drying chamber 110 through the outlet 130, the air supply assembly 230 continues to blow hot air towards the glass to further heat it, ensuring that all water droplets on the glass surface are completely evaporated, thus improving the reliability of the drying device 10.

[0041] It should be noted that the process of the conveying device transporting glass through the inlet 120 refers to the entire process from when the glass on the conveying device is a preset distance away from the inlet 120 (before the glass enters the inlet 120) until the glass has completely passed through the inlet 120. The process of the conveying device transporting glass through the outlet 130 refers to the entire process from when the glass on the conveying device is transported to the outlet 130 until the glass has completely passed through the outlet 130 and is a preset distance away from the outlet 130. The value of the preset distance can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the preset distance is set to a range of 0cm to 50cm. For example, the preset distance can be 0cm, 10cm, 20cm, 30cm, or 40cm, etc.

[0042] The hot air generating component 220 can be configured as any structure capable of generating hot air in the prior art. For example, the hot air generating component 220 can be configured as a blowing structure (e.g., a blower) with a built-in heating element 211 (e.g., a heating resistor).

[0043] like Figure 1 and Figure 2 As shown, the air supply assembly 230 further includes a first air supply duct 231 and a first nozzle 232. The first air supply duct 231 connects the hot air generating assembly 220 and the first nozzle 232. The first nozzle 232 is located at the feed inlet 120 and is configured to blow air onto the glass as the conveying device transports the glass through the feed inlet 120. In this way, the first nozzle 232 can uniformly blow hot air onto the glass, allowing the glass to heat up evenly, ensuring that all water droplets on the glass surface are completely removed, and improving the reliability of the drying device 10.

[0044] Specifically, in this embodiment, the first nozzle 232 is located at the top of the inlet 120 and extends along the width direction of the inlet 120. Along the width direction of the inlet 120, the width of the air outlet of the first nozzle 232 is greater than or equal to the width of the glass to ensure that the hot air can fully cover the glass surface.

[0045] like Figure 2As shown, optionally, the first air supply duct 231 includes a horizontal duct 2311, an air passage plate 2312, and a vertical duct 2313. The number of horizontal ducts 2311 and vertical ducts 2313 is at least one. One end of each horizontal duct 2311 is connected to the hot air generating assembly 220, and the other end of each horizontal duct 2311 is spaced apart along the extension direction of the air passage plate 2312 and connected to the air passage plate 2312. One end of each vertical duct 2313 is spaced apart along the extension direction of the air passage plate 2312 and connected to the air passage plate 2312, and the other end of each vertical duct 2313 is spaced apart along the extension direction of the first nozzle 232 and connected to the first nozzle 232. Thus, the multiple spaced horizontal pipes 2311 can make the hot air more evenly distributed in the air passage plate 2312, and the multiple spaced vertical pipes 2313 can make the hot air more evenly distributed in the first nozzle 232, ensuring that the hot air can be evenly sprayed out from the first nozzle 232, thereby improving the reliability of the drying device 10.

[0046] The number of horizontal tubes 2311 and vertical tubes 2313 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, there is one horizontal tube 2311 and three vertical tubes 2313. The air passage plate 2312 is provided with an airflow channel arranged along the extension direction of the air passage plate 2312, and the airflow channel is connected to each horizontal tube 2311 and each vertical tube 2313. The extension direction of the air passage plate 2312, the extension direction of the first nozzle 232, and the width direction of the feed inlet 120 are all parallel.

[0047] Optionally, the drying device 10 also includes a feed detection element and a controller. The controller is communicatively connected to both the first nozzle 232 and the feed detection element. The feed detection element is installed at the feed inlet 120 and is used to detect whether there is glass at the feed inlet 120. The first nozzle 232 has an open state and a closed state. Thus, when the feed detection element detects glass, it feeds the detection result back to the controller. The controller sends an open signal to the first nozzle 232 based on the detection result, and the first nozzle 232 switches to the open state to blow hot air into and out of the glass. When the glass passes through the feed inlet 120, the feed detection element no longer detects glass and feeds the detection result back to the controller. The controller sends a close signal to the first nozzle 232 based on the detection result, and the first nozzle 232 switches to the closed state to stop blowing hot air, realizing intelligent hot air drying control and improving the practicality of the drying device 10.

[0048] The feeding detection element can be configured as an infrared sensor, a camera, or other structure capable of detecting glass feeding. The feeding detection element can be installed on the drying body 100 at the feed inlet 120 via snap-fit, screw-fit, plug-in, or other methods. The controller can be configured as a microcontroller, a programmable logic controller, or other control structure. The controller can be set up independently or integrated with the power supply and hot air generating assembly 220. The controller can communicate with the hot air generating mechanism, the first nozzle 232, and the feeding detection element via wires, data cables, Bluetooth, wireless network communication technology, or other means.

[0049] In this specific implementation, the controller is also equipped with an overheat protection mechanism. Once the temperature exceeds the safe range, the controller sends a cut-off signal to the hot air generating component 220. The hot air generating component 220 immediately and automatically cuts off the hot air supply according to the cut-off signal to ensure operational safety.

[0050] Optionally, the drying device 10 further includes a first temperature sensor for detecting the hot air temperature, which is installed at the air outlet of the first nozzle 232. The first temperature sensor is communicatively connected to the controller. Thus, the first temperature sensor can monitor the temperature of the air outlet of the first nozzle 232 in real time and feed it back to the controller. This allows the controller to send a temperature adjustment signal to the hot air generating component 220 based on the real-time temperature feedback. The hot air generating component 220 adjusts the temperature of the generated hot air accordingly based on the temperature adjustment signal, ensuring optimal drying effect at the feed inlet 120 while preventing damage to the glass and improving the drying effect of the drying device 10.

[0051] Optionally, the drying device 10 further includes a first flow rate detection element for detecting the hot air flow rate, which is installed at the air outlet of the first nozzle 232. The first flow rate detection element is communicatively connected to the controller. Thus, the first flow rate detection element can monitor the flow rate at the air outlet of the first nozzle 232 in real time and feed it back to the controller. This allows the controller to send a flow rate adjustment signal to the hot air generating component 220 based on the real-time flow rate feedback. The hot air generating component 220 adjusts the flow rate of the generated hot air accordingly based on the flow rate adjustment signal, ensuring optimal drying effect at the feed inlet 120 while preventing damage to the glass and improving the drying effect of the drying device 10.

[0052] The first temperature detection element can be configured as a temperature sensor, thermometer, or other temperature detection structure. The first flow rate detection element can be configured as a flow rate sensor, flow meter, or other flow rate detection structure. The controller can communicate with both the first temperature detection element and the first flow rate detection element via wires, data cables, Bluetooth, wireless network communication technology, or other means.

[0053] like Figure 1 and Figure 2As shown, in one embodiment, the air supply assembly 230 includes a second air supply duct 233 and a second nozzle 234. The second air supply duct 233 connects the hot air generating assembly 220 and the second nozzle 234. The second nozzle 234 is located at the outlet 130 and is configured to blow hot air onto the glass as the conveying device transports the glass through the outlet 130. Thus, as the conveying device transports the glass out of the drying chamber 110 from the outlet 130, the second nozzle 234 continues to blow hot air toward the glass to continue heating it, ensuring that water droplets on the glass surface are completely evaporated, thereby improving the reliability of the drying device 10.

[0054] Specifically, in this embodiment, the second air supply duct 233 and the first air supply duct 231 are symmetrically arranged on both sides of the drying chamber 110. The second nozzle 234 and the first nozzle 232 are also symmetrically arranged on both sides of the drying chamber 110. The outlet of the second nozzle 234 is also equipped with a second temperature sensor and a second flow rate sensor, the working principle of which is the same as that of the first temperature sensor and the first flow rate sensor at the outlet of the first nozzle 232, and will not be described in detail here.

[0055] Optionally, the drying device 10 also includes a discharge detection element that is communicatively connected to the controller. The discharge detection element is installed at the discharge port 130 and is used to detect whether there is glass at the discharge port 130. The structure and working principle of the discharge detection element are the same as those of the infeed detection element, and will not be described in detail here.

[0056] like Figure 1 As shown, in one embodiment, the drying body 100 includes a frame 140 with an inlet 120 and an outlet 130, an insulation partition 150, an observation door / window 160, and a handle 170. The inlet 120 and the outlet 130 are located on opposite sides of the frame 140. There is at least one insulation partition 150, an observation door / window 160, and a handle 170. Each insulation partition 150 and each observation door / window 160 is mounted on the frame 140, such that the insulation partition 150, each observation door / window 160, and the frame 140 can enclose and form a drying chamber 110. Each handle 170 is correspondingly mounted on the side of each observation door / window 160 facing away from the drying chamber 110. Thus, the insulation partition 150 uses high-efficiency heat insulation material, which can effectively reduce heat loss and energy consumption; the observation door and window 160 allows operators to intuitively view the internal condition of the equipment; the handle 170 is used to open the observation door and window 160, which facilitates maintenance and repair and improves the practicality of the drying device 10.

[0057] In one embodiment, a photovoltaic module production system is provided, including a transmission device and a drying device 10 as described in any of the above embodiments, wherein the transmission device is disposed within the drying device 10.

[0058] In the photovoltaic module production system described above, the drying device 10 is installed on the conveying device, allowing the conveying device to pass through the conveying channel. The drying device 10 does not affect the layout or production efficiency of the photovoltaic module production system. During the process of the conveying device transporting glass through the conveying channel, the heating structure 200 heats the glass, rapidly increasing its temperature to evaporate water droplets on the glass surface. This ensures that the glass surface is free of water droplets during subsequent film lamination and bonding processes, preventing slippage or misalignment between the film and the glass due to insufficient friction, thus improving the production quality and efficiency of the photovoltaic modules.

[0059] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not 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 application.

[0060] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0061] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0062] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via 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. Similarly, "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.

[0063] It should be noted that if 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. If 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. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0064] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
