[0040] Reference Figure 1 、 Figure 3 as well as Figure 5 As shown, the back panel 21 peeling device involved in the embodiment of the present application includes: a frame 100 and a peeling assembly 200.

[0041] Specifically, the stripping assembly 200 is arranged on the frame 100, and the stripping assembly 200 includes a scraper 210 and a heating element 220. The scraper 210 is arranged between the glass 22 and the back panel 21, and the scraper 210 is used to move relative to the photovoltaic assembly 20 along a first direction. The heating element 220 is arranged on the scraper 210, and the heating element 220 is used to heat the scraper 210.

[0042] It should be noted that the first direction is Figure 2 The direction pointed by x.

[0043] It should be noted that, in the photovoltaic module 20 , the back panel 21 and the glass 22 are usually bonded by an adhesive. In some embodiments, the adhesive is an EVA (ethylene-vinyl acetate copolymer) adhesive. The EVA adhesive can be softened by heating to achieve separation of the back panel 21 and the glass 22 .

[0044] In the back panel 21 peeling device of the present application, since the scraper 210 is arranged between the glass 22 and the back panel 21, and the heating element 220 can heat the scraper 210, the heated scraper 210 can soften the back panel 21 and the glue between the back panel 21 and the glass 22, thereby facilitating the separation of the back panel 21 from the glass 22. Since the scraper 210 is used to move relative to the photovoltaic module 20 along the first direction, when the scraper 210 and the photovoltaic module 20 move relative to each other along the first direction, the scraper 210 can peel the back panel 21 from the glass 22. In this process, there is no need to heat the entire photovoltaic module 20, only the scraper 210 needs to be heated. In this way, the energy consumption generated during the heating process can be reduced, thereby reducing the energy consumption in the process of peeling the back panel 21.

[0045] Specifically, in some embodiments, the relative movement of the scraper 210 and the photovoltaic component 20 along the first direction is the movement of the scraper 210 relative to the photovoltaic component 20 along the first direction; in some embodiments, the relative movement of the scraper 210 and the photovoltaic component 20 along the first direction is the movement of the photovoltaic component 20 relative to the scraper 210 along the first direction; in other embodiments, the relative movement of the scraper 210 and the photovoltaic component 20 along the first direction is the movement of the photovoltaic component 20 and the scraper 210 relative to each other along the first direction.

[0046] Reference Figure 1 、 Figure 2 as well as Figure 4 As shown, in this embodiment, the backboard 21 peeling device also includes a first conveying component 300, which is arranged on the frame 100, and the first conveying component 300 is extended along the first direction and transmitted along the first direction. The first conveying component 300 is used to convey the photovoltaic component 20 along the first direction, and the scraper 210 is arranged near the conveying end of the first conveying component 300.

[0047] Specifically, in this embodiment, the relative movement of the scraper 210 and the photovoltaic assembly 20 along the first direction is the movement of the photovoltaic assembly 20 relative to the scraper 210 along the first direction.

[0048] In this embodiment, since the first conveying component 300 is extended along the first direction and transmitted along the first direction, and the first conveying component 300 is used to convey the photovoltaic component 20 along the first direction, the photovoltaic component 20 can be conveyed along the first direction by the first conveying component 300, so that the photovoltaic component 20 can move along the first direction relative to the scraper 210. Since the scraper 210 is arranged close to the conveying end of the first conveying component 300, when the first conveying component 300 conveys the photovoltaic component 20 along the first direction, the photovoltaic component 20 can be moved toward the direction close to the scraper 210, so that the scraper 210 can pass through various parts of the photovoltaic component 20 along the first direction, thereby achieving the purpose of peeling the back panel 21 from the glass 22.

[0049] Reference Figure 2 As shown, the first conveying component 300 includes a first conveying member 310 and a second conveying member 320. The first conveying member 310 and the second conveying member 320 are both arranged on the frame 100 and arranged side by side along the second direction. The first conveying member 310 and the second conveying member 320 are respectively used to be tightly attached to the two sides of the photovoltaic component 20 along the second direction. The first conveying member 310 and the second conveying member 320 are both transmitted along the first direction; wherein the second direction is perpendicular to the first direction.

[0050] It should be noted that the second direction is Figure 2 The direction indicated by y.

[0051] Specifically, in this embodiment, the first conveying member 310 and the second conveying member 320 are both conveyor belts, and the first conveying member 310 and the second conveying member 320 are driven in opposite directions in the first direction, so that the photovoltaic component 20 located between the first conveying member 310 and the second conveying member 320 can be conveyed along the first direction.

[0052] In this embodiment, since the first conveying member 310 and the second conveying member 320 are respectively used to be tightly attached to the two sides of the photovoltaic component 20 along the second direction, and the first conveying member 310 and the second conveying member 320 are both transmitted along the first direction, the photovoltaic component 20 can be transmitted along the first direction through the first conveying member 310 and the second conveying member 320. In this process, the photovoltaic component 20 can also be clamped by the first conveying member 310 and the second conveying member 320, so that the photovoltaic component 20 can be limited by the first conveying member 310 and the second conveying member 320. When the scraper 210 is peeling off the backboard 21, the photovoltaic component 20 can be prevented from moving along the second direction, thereby facilitating the peeling of the backboard 21 from the glass 22.

[0053] Reference Figure 1As shown, the stripping assembly 200 also includes a gas filter 400, which is arranged on the frame 100, and the gas filter 400 is arranged near the conveying end of the first conveying assembly 300, and the gas filter 400 is covered on the scraper 210, and the scraper 210 is connected to the inner wall of the gas filter 400.

[0054] It should be noted that when EVA adhesive is heated, it will first undergo thermal decomposition, producing a large amount of smoke and toxic gases, such as CO (carbon monoxide), CO2 (carbon dioxide), CH (benzene) and HCl (hydrogen chloride). Among them, CO and HCl (hydrogen chloride) are the main toxic gases, which will seriously affect the function of the human respiratory system and cause harm to human health. In addition, EVA plastic will also produce black smoke and oil smoke at high temperatures.

[0055] Specifically, in this embodiment, the gas filter 400 extracts harmful gases by vacuuming.

[0056] In this embodiment, since the gas filter 400 is arranged on the frame 100 and the scraper 210 is connected to the inner wall of the gas filter 400, the scraper 210 can be fixed by the gas filter 400. When the heated scraper 210 peels the back plate 21 from the glass 22, the heated scraper 210 will heat and soften the EVA adhesive. In this process, the EVA adhesive will produce harmful gases. Since the gas filter 400 is covered on the scraper 210, the harmful gases can be filtered by the gas filter 400 to prevent the harmful gases from causing harm to human health.

[0057] Reference Figure 2 As shown, the back panel 21 peeling device also includes a second conveying assembly 500, and the gas filter 400 is simultaneously covered on the scraper 210 and the second conveying assembly 500, and the second conveying assembly 500 is connected to the gas filter 400. The second conveying assembly 500 is arranged on the side of the scraper 210 along the first direction close to the conveying end of the first conveying assembly 300, and the second conveying assembly 500 is used to convey the peeled back panel 21 along the first direction.

[0058] In this embodiment, the second conveying assembly 500 can be fixed by the gas filter 400 so that the second conveying assembly 500 can realize the conveying function, and the harmful gases generated on the separated back panel 21 and the glass 22 can be absorbed by the gas filter 400. Since the second conveying assembly 500 is arranged on the side of the scraper 210 away from the first conveying assembly 300 along the first direction, the second conveying assembly 500 is used to convey the peeled back panel 21 along the first direction. In this way, after the back panel 21 is gradually peeled off from the glass 22 by the scraper 210, the peeled back panel 21 can be conveyed along the first direction toward the direction away from the scraper 210 by the second conveying assembly 500 to achieve complete separation of the back panel 21 and the peeled back panel.

[0059] Specifically, in this embodiment, when the second conveying assembly 500 conveys the peeled backing plate 21 along the first direction toward the direction away from the scraper 210, the glass 22 separated from the backing plate 21 can continue to be conveyed along the first direction toward the direction away from the scraper 210 on the first conveying assembly 300 to achieve complete separation of the backing plate 21 from the peeling.

[0060] Reference Figure 3 as well as Figure 5 As shown, the second conveying assembly 500 includes a third conveying member 510 and a fourth conveying member 520. The third conveying member 510 and the fourth conveying member 520 are both connected to the inner wall of the gas filter 400 and are arranged side by side along the second direction. The third conveying member 510 and the fourth conveying member 520 are respectively used to tightly adhere to the two sides of the peeled back plate 21 along the second direction. The third conveying member 510 and the fourth conveying member 520 are both transmitted along the first direction.

[0061] Specifically, in this embodiment, the third conveying member 510 and the fourth conveying member 520 are both conveyor belts, and the third conveying member 510 and the fourth conveying member 520 are driven in opposite directions in the first direction, so that the back plate 21 located between the third conveying member 510 and the fourth conveying member 520 can be conveyed along the first direction.

[0062] In this embodiment, since the third conveying member 510 and the fourth conveying member 520 are respectively used to be tightly attached to the two sides of the peeled backing plate 21 along the second direction, and the third conveying member 510 and the fourth conveying member 520 are both transmitted along the first direction, the third conveying member 510 and the fourth conveying member 520 can realize the transmission of the peeled backing plate 21 along the first direction. In this process, the third conveying member 510 and the fourth conveying member 520 can also form a clamping shape on the backing plate 21 to ensure that the backing plate 21 can move along the first direction on the second conveying component 500, so as to form a pulling force on the backing plate 21 along the first direction away from the scraper 210 through the second conveying component 500, thereby facilitating the separation of the backing plate 21 from the peeling.

[0063] Continue to refer to Figure 3 as well as Figure 5 As shown, the second conveying assembly 500 is arranged on a side of the scraper 210 along the second direction toward the back plate 21, and the peeling assembly 200 also includes a guide 230, which is arranged on a side of the scraper 210 close to the second conveying assembly 500, and the guide 230 is used to be arranged on a side of the back plate 21 close to the scraper 210 along the second direction. In the first direction, one end of the guide 230 is flush with the end of the scraper 210 away from the second conveying assembly 500, and the other end of the guide 230 is flush with the end of the second conveying assembly 500 close to the scraper 210.

[0064] In this embodiment, since the guide member 230 is provided on the side of the scraper 210 close to the second conveying assembly 500, and the guide member 230 is used to be provided on the side of the back plate 21 close to the scraper 210 along the second direction, when the back plate 21 is peeled off from the glass 22 by the scraper 210, the peeled back plate 21 can move to the guide member 230 along the first direction. In the first direction, since one end of the guide member 230 is flush with the end of the scraper 210 away from the second conveying assembly 500, the guide member 230 is provided on the side of the back plate 21 along the second direction. 0 is flush with one end of the second conveying assembly 500 close to the scraper 210. Therefore, the back panel 21 moved onto the guide member 230 can enter the second conveying assembly 500 through the guiding effect of the guide member 230, so that the second conveying assembly 500 can convey the peeled back panel 21 along the first direction and away from the scraper 210. In this way, the guide member 230 can provide a guiding effect for the back panel 21 to ensure that the peeled back panel 21 can move along the first direction to the second conveying assembly 500.

[0065] Reference Figure 6 As shown, the scraper 210 has a blade portion 211, which is arranged at one end of the scraper 210 away from the conveying end of the first conveying assembly 300 along the first direction, and the blade portion 211 is connected to the inner wall of the gas filter 400, and the blade portion 211 has a slope surface 2111, which is inclined along a direction at an angle to the first direction.

[0066] In this embodiment, since the blade portion 211 is arranged at one end of the scraper 210 away from the conveying end of the first conveying component 300 along the first direction, the back plate 21 can be peeled off by the blade portion 211. Since the blade portion 211 has a sloped surface 2111, the sloped surface 2111 is inclined in a direction at an angle to the first direction. In this way, the blade portion 211 can be formed into a trapezoidal structure. The trapezoidal structure of the blade portion 211 can reduce the friction between the blade portion 211 and the back plate 21, thereby reducing the difficulty of the blade portion 211 in peeling off the back plate 21.

[0067] Continue to refer to Figure 6 As shown, the scraper 210 also has a heating part 212, which is connected to the inner wall of the gas filter 400, and the heating part 212 is connected to the blade part 211, and is arranged at one end of the blade part 211 along the first direction close to the conveying end of the first conveying component 300, and the heating element 220 is arranged on the heating part 212.

[0068] In this embodiment, since the heating element 220 is arranged on the heating portion 212 and the heating portion 212 is connected to the blade portion 211, the heating portion 212 can be heated by the heating element 220, and the blade portion 211 can be further heated by the heating portion 212, thereby reducing the difficulty of the blade portion 211 in peeling off the back panel 21.

[0069] Specifically, continue to refer to Figure 6 As shown, in this embodiment, the heating element 220 is a heating rod, the heating portion 212 is provided with a mounting hole 2121 , and the heating rod is inserted into the mounting hole 2121 to heat the heating portion 212 through the heating rod.

[0070] Specifically, in this embodiment, when the heating element 220 heats the scraper 210, the temperature of the scraper 210 is heated to T℃, satisfying: 150℃≤T≤250℃. If T<150℃, the EVA adhesive cannot be heated to soften, resulting in difficulty in peeling off the back panel 21. If T>250℃, it will lead to excessive heating energy consumption, and at the same time, the back panel 21 and the peeling device will be at risk of being burned, and further the back panel 21 peeling device will be at risk of being burned. When 150℃≤T≤250℃, it can not only soften the EVA adhesive and reduce the difficulty of peeling off the back panel 21 and glass 22, but also reduce energy consumption and reduce the risk of burning the back panel 21 peeling device.

[0071] Specifically, in this embodiment, the surface of the scraper 210 is coated with a Teflon coating. The Teflon coating can not only enhance the durability of the scraper 210 , but also prevent the scraper 210 from adhering to the adhesive, thereby ensuring the smoothness of the peeling process of the back plate 21 .

[0072] Reference Figure 2 As shown, the scraper 210 is further configured to move along a third direction relative to the photovoltaic assembly 20 ; wherein the third direction is arranged at an angle to the first direction.

[0073] Specifically, in this embodiment, the third direction is perpendicular to the first direction and the second direction, and the third direction is Figure 2 The direction indicated by z.

[0074] In this embodiment, since the scraper 210 is also used to move along the third direction relative to the photovoltaic module 20, when the scraper 210 peels off the backboard 21, the scraper 210 moving along the third direction can speed up the separation of the backboard 21 and reduce the difficulty of the scraper 210 peeling off the backboard 21.

[0075] Specifically, in this embodiment, the scraper 210 performs periodic left-right vibration in the third direction, and the vibration is controlled by a precise mechanical system, which can prevent it from exceeding the resonance frequency of 20000HZ of the glass 22 to ensure the uniformity and consistency of the back panel 21 peeling process.
