[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0033] refer to Figure 1 and Figure 2 As shown, an embodiment of this application provides a photovoltaic module recycling device 100, which includes a frame 110, a heating component 120, a conveying component 130, and a cutting component 140.
[0034] Specifically, in combination Figure 2 and Figure 3As shown, the heating component 120 is mounted on the frame 110. The conveying component 130 is disposed on the frame 110, and the conveying component 130 is located between the heating component 120 and the frame 110. An inlet end 131 and an outlet end 132 are respectively provided at opposite ends along the conveying direction of the conveying component 130. The conveying component 130 enables the photovoltaic module to be conveyed and moved on the frame 110. The photovoltaic module enters through the inlet end 131 of the conveying component 130. The heating component 120 is provided to heat and soften the photovoltaic module to facilitate subsequent disassembly and cutting of the photovoltaic module's backsheet and photovoltaic glass.
[0035] In this embodiment, the cutting assembly 140 is disposed at the output end 132. The cutting assembly 140 includes a limiting member 141, a cutting member 142, and a pressure roller 143. The cutting member 142 is disposed opposite to the pressure roller 143 and can rotate relative to it. The cutting member 142 can move closer to or further away from the pressure roller 143. One end of the limiting member 141 extends toward the feed end 131 of the conveying assembly 130. Accordingly, the limiting member 141 is used to limit the heated and softened photovoltaic module. To prevent warping, the cutting element 142 and the pressure roller 143 work together to cut and recycle the photovoltaic glass. The photovoltaic module is placed between the cutting element 142 and the pressure roller 143. During the cutting process, the pressure roller 143 supports and limits the photovoltaic module, keeping the cutting element 142 close to or away from the photovoltaic module to avoid cutting too deeply and damaging the photovoltaic module. The cutting element 142 cuts and breaks the photovoltaic glass during relative rotation, reducing slippage and displacement of the photovoltaic glass during the cutting process and improving the cutting effect.
[0036] like Figure 1 and Figure 2 As shown, the photovoltaic module recycling device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the length direction of the photovoltaic module recycling device 100, the second direction Y refers to the width direction of the photovoltaic module recycling device 100, and the third direction Z refers to the height direction of the photovoltaic module recycling device 100. It is understood that the above definitions are only for the purpose of understanding the relative positional relationships of the various parts in the photovoltaic module recycling device 100 and should not be construed as limiting this application.
[0037] For example, the conveying component 130 is provided with a conveyor belt, and the conveying movement direction of the conveyor belt is the first direction X. The conveyor belt conveys the photovoltaic module material to the position of the heating component 120 or the cutting component 140, so as to facilitate the disassembly and recycling of the photovoltaic module, improve the automation level of the photovoltaic module recycling device 100, and reduce the labor intensity of personnel.
[0038] Understandably, the heating component 120 can use infrared heating or electromagnetic induction heating to soften the photovoltaic module, bringing the EVA film and other thermoplastic materials in the photovoltaic module to a softening temperature (typically between 80°C and 120°C), facilitating the separation of the photovoltaic glass and the backsheet. The photovoltaic module recycling device 100 is also equipped with a control component, which is electrically connected to the heating component 120, the conveying component 130, and the cutting component 140, respectively, to control the operation of the photovoltaic module recycling device 100 for processing and recycling the photovoltaic modules.
[0039] In one embodiment, reference Figure 3 and Figure 4 As shown, optionally, the cutting element 142 is movably connected to the frame 110, and the cutting element 142 is surrounded by a plurality of serrated portions 1421, with a gap 1422 formed between adjacent serrated portions 1421. That is, the cutting element 142 rotates relative to the photovoltaic module to cut the photovoltaic glass. A drive motor can be used to drive the cutting element 142 to rotate, and the cutting element 142 moves relative to the pressure roller 143 to adjust the cutting depth of the photovoltaic module, so that the cutting element 142 is closer to or further away from the photovoltaic module, avoiding over-cutting and damage to the photovoltaic module. The gap 1422 facilitates the discharge of cutting debris by rotating the cutting element 142 during the cutting of the photovoltaic module.
[0040] For example, the cutting element 142 moves relative to the lead screw driven by a motor. According to the command issued by the control component, the stepper motor rotates at a certain angle, and the lead screw converts the rotational motion into linear motion, which drives the cutting element 142 to move along the lead screw axis, so that the cutting element 142 moves closer to the pressure roller 143 or away from the pressure roller 143, thereby adjusting the relative distance between the cutting element 142 and the pressure roller 143.
[0041] In one embodiment, reference Figure 1 and Figure 2 As shown, optionally, the photovoltaic module recycling device 100 further includes a collection component 150, which is connected to the frame 110 and is disposed opposite to the cutting component 140. The collection component 150 is used to collect photovoltaic materials, such as photovoltaic glass, silicon wafers, and metal electrodes, from the cut and dismantled photovoltaic modules, thereby improving recycling efficiency.
[0042] In summary, the photovoltaic module recycling device 100 uses a conveying component 130 to move the photovoltaic modules on a frame 110. The photovoltaic modules enter through the feed end 131 of the conveying component 130. A heating component 120 is used to heat and soften the photovoltaic modules to facilitate subsequent disassembly and cutting of the backsheet and photovoltaic glass. A limiting component 141 is used to limit the heated and softened photovoltaic modules to prevent warping. A cutting component 142 and a pressure roller 143 work together to cut and recycle the photovoltaic glass. The photovoltaic modules are placed between the cutting component 142 and the pressure roller 143. During the cutting process, the pressure roller 143 supports and limits the photovoltaic modules, keeping the cutting component 142 close to or away from the photovoltaic modules to avoid cutting too deeply and damaging the photovoltaic modules. The cutting component 142 cuts and breaks the photovoltaic glass during relative rotation, reducing slippage and displacement of the photovoltaic glass during cutting, improving the cutting effect, and thus achieving the recycling and sorting of photovoltaic modules.
[0043] refer to Figures 1 to 3 As shown, an embodiment of this application provides another photovoltaic module recycling device 100, which includes a frame 110, a heating component 120, a conveying component 130, and a cutting component 140.
[0044] Specifically, in combination Figure 2 and Figure 3As shown, the heating assembly 120 is mounted on the frame 110. The conveying assembly 130 is disposed on the frame 110 and is located between the heating assembly 120 and the frame 110. An inlet end 131 and an outlet end 132 are respectively provided at opposite ends along the conveying direction of the conveying assembly 130. The cutting assembly 140 is disposed at the output end 132. The cutting assembly 140 includes a limiting member 141, a cutting member 142, and a pressure roller 143. The cutting member 142 is disposed opposite to the pressure roller 143 and can rotate relative to it. The cutting member 142 can move closer to or further away from the pressure roller 143. One end of the limiting member 141 extends toward the feed end 131 of the conveying assembly 130. Correspondingly, the conveying assembly 130 causes the photovoltaic module to move and be conveyed on the frame 110. The photovoltaic module enters through the feed end 131 of the conveying assembly 130. A heating assembly 120 is provided to heat and soften the photovoltaic module to facilitate... The backsheet and photovoltaic glass of the photovoltaic module are then disassembled and cut. The limiting component 141 is used to limit the photovoltaic module after it has been heated and softened to prevent warping. The cutting component 142 and the pressure roller 143 work together to cut and recycle the photovoltaic glass. The photovoltaic module is placed between the cutting component 142 and the pressure roller 143. During the cutting process, the pressure roller 143 supports and limits the photovoltaic module, so that the cutting component 142 is close to or away from the photovoltaic module, avoiding excessive cutting that could damage the photovoltaic module. The cutting component 142 cuts and breaks the photovoltaic glass during relative rotation, reducing slippage and displacement of the photovoltaic glass during the cutting process and improving the cutting effect.
[0045] In one embodiment, reference Figure 3 and Figure 4 As shown, optionally, the cutting element 142 is movably connected to the frame 110, and the cutting element 142 is surrounded by a plurality of serrated portions 1421, with gaps 1422 formed between adjacent serrated portions 1421. This allows the cutting element 142 to cut the photovoltaic glass of the photovoltaic module by relative rotation. The cutting depth of the cutting element 142 can be adjusted, allowing it to be closer to or further away from the photovoltaic module to avoid over-cutting and damage. The gaps 1422 facilitate the removal of cutting debris during the cutting process by rotating the cutting element 142. Exemplarily, each serrated portion 1421 is arranged parallel to the second direction Y, ensuring a good cutting effect when the multiple serrated portions 1421 cut the photovoltaic module.
[0046] Furthermore, such as Figure 4As shown, the cutting component 142 is a cylindrical structure. The cylindrical cutting component 142 is circumferentially surrounded by multiple serrated portions 1421, so that when the cylindrical cutting component 142 rotates relative to the photovoltaic module, the serrated portions 1421 can cut the photovoltaic module, reducing the occurrence of the serrated portions 1421 getting stuck in the photovoltaic module, and further improving the cutting and dismantling efficiency.
[0047] Optionally, combined Figure 1 and Figure 3 As shown, the cutting element 142 is arranged parallel to the pressure roller 143, and the rotation axis of the cutting element 142 is perpendicular to the first direction X. The distance between the cutting element 142 and the pressure roller 143 can be adjusted so that the cutting element 142 can cut and disassemble one side of the photovoltaic module. The distance between the cutting element 142 and the pressure roller 143 can be adjusted according to the thickness and size specifications of the photovoltaic module to achieve more precise control of the cutting depth and cutting speed of the cutting element 142, avoid damage to the silicon wafer and metal electrodes in the photovoltaic module during the cutting process, and improve the cutting effect.
[0048] In addition, after heating and softening the photovoltaic glass on one side of the photovoltaic module, the photovoltaic glass is cut and disassembled by the cutting component 140. The photovoltaic glass on the other side of the photovoltaic module is then heated and softened by the heating component 120, which facilitates the cutting and disassembly of the photovoltaic glass on the other side of the photovoltaic module. This achieves the separation and disassembly of the double-sided glass of the photovoltaic module, so as to facilitate the recycling of the relevant components of the photovoltaic module.
[0049] In one embodiment, reference Figure 1 and Figure 3 As shown, optionally, the photovoltaic module recycling device 100 further includes a feed baffle 160, which is disposed at the feed end 131. The feed baffle 160 is used to limit the photovoltaic module material entering the conveying component 130 through the feed end 131, preventing the photovoltaic module from deviating from the conveying component 130 during the feeding process, avoiding the situation where the photovoltaic module cannot be properly transmitted, and ensuring the accuracy of feeding.
[0050] Optionally, such as Figure 3As shown, the feed baffle 160 includes a first baffle 161 and a second baffle 162. The first baffle 161 is disposed on opposite sides of the conveying assembly 130 along the first direction X. The second baffle 162 is connected to the heating assembly 120 and is installed above the conveying assembly 130. In other words, the first baffle 161 is used to limit and regulate the width of the photovoltaic module material, and the second baffle 162 is installed on the heating assembly 120 and is used to limit the height of the photovoltaic module material to avoid the photovoltaic module being too high and the heating assembly 120 obstructing each other.
[0051] Furthermore, the second baffle 162 extends toward the end opposite to the conveying assembly 130 to form a curved portion, that is, the second baffle 162 extends and curves along the end opposite to the conveying assembly 130, so that the curved portion of the second baffle 162 is an arc-shaped structure. During the standardization and limiting process, the height of the photovoltaic module material will not affect the normal movement of the photovoltaic module on the conveying assembly 130 along the first direction X.
[0052] In one embodiment, reference Figure 1 and Figure 2 As shown, optionally, the photovoltaic module recycling device 100 further includes a collection component 150, which is connected to the frame 110 and is disposed opposite to the cutting component 140. The collection component 150 is used to collect photovoltaic materials in the cut and dismantled photovoltaic modules, thereby improving recycling efficiency.
[0053] Optionally, the collection assembly 150 includes a collection box and a buffer. The buffer is disposed inside the collection box, and the space inside the collection box is used to place the relevant material components of the photovoltaic module. The buffer provides a certain elastic cushioning effect to reduce the possibility of the photovoltaic glass breaking due to inertia when it falls into the collection box. For example, the collection box is detachably connected to the frame 110, that is, the collection box can be installed on the frame 110, or the collection box can be removed from the frame 110 for material handling and replacement.
[0054] Further, refer to Figure 2 As shown, the cutting assembly 140 also includes a feeding component 144, one end of which extends into the collecting assembly 150. The height of the collecting assembly 150 is less than the height of the cutting assembly 140. The feeding component 144 serves as a guide. Because the height of the cutting assembly 140 is greater than the height of the collecting assembly 150, the relevant material components of the photovoltaic module fall under the influence of gravity, allowing them to fall more accurately into the collecting assembly 150. For example, the feeding component 144 is a feeding hopper, which is inclined so that one end extends into the collecting box.
[0055] The present invention also provides a recycling system, including the photovoltaic module recycling device 100 in embodiment 1 or embodiment 2. The recycling system including the photovoltaic module recycling device 100 has all the beneficial effects of the photovoltaic module recycling device 100, which will not be described in detail here.
[0056] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0057] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
