[0001] The utility model belongs to the technical field of photovoltaic component recycling equipment, in particular to an automatic stripping device for a solar panel back sheet. [Background technology]

[0002] Photovoltaic modules are a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Photovoltaic modules generally consist of glass panels, EVA adhesive layers, cells, back panels, junction boxes and frames, etc. More than 90% of the materials can be recycled and reused, with considerable recycling value and high economic profits. Therefore, photovoltaic modules that have reached their lifespan need to be recycled, which not only alleviates the shortage of raw materials for photovoltaic devices to a certain extent, but also avoids pollution to the environment.

[0003] When recycling photovoltaic modules, the cell module and the adhesive backing must first be peeled off the glass, so a backboard peeling mechanism is needed. Patent CN219696471U in the prior art discloses a photovoltaic module backboard removal system, which first performs edge raising on the backboard, then heats and softens it, and then peels the backboard through a backboard peeling device. Although the removal system can automatically peel the backboard, the overall equipment structure is complicated and occupies a large space; the backboard must be edge raised before peeling, and after the backboard is softened, the backboard end is clamped by a clamp and lifted from the photovoltaic module, and then the peeling roller assembly is clamped and rotated to achieve backboard peeling, and the peeling operation involves many actions.

[0004] Therefore, it is necessary to provide a new solar panel back sheet automatic peeling device to solve the above technical problems. [Contents of the utility model]

[0007] Furthermore, the upper surface of the scraper is higher than the upper surface of the second bottom supporting plate and lower than the lower surface of the second upper limit plate.

[0008] Furthermore, it also includes a cylinder group, which always applies an upward force on the scraper.

[0009] Furthermore, a backplane collection box is provided below the backplane output port.

[0011] Furthermore, it also includes an introduction plate group that guides the solar panels on the roller conveyor line into the feeding module and a guide output plate located on the output side of the upper part of the scraper.

[0012] Furthermore, the introduction plate group includes a first bottom support plate and a first upper limit plate located above the first bottom support plate; an introduction channel is formed between the first bottom support plate and the first upper limit plate; the input side of the introduction channel is connected to the roller conveyor line, and the output side thereof is connected to the feeding port.

[0030] Embodiment 1:

[0031] Please refer to Figure 1-Figure 4 The present embodiment is a solar panel back sheet automatic peeling device 100, which includes a roller conveyor line 1, a heating module 2 arranged on the upper and lower sides of the roller conveyor line 1, a feeding module 3 located on the output side of the roller conveyor line 1, an introduction plate group 4 for introducing the solar panels on the roller conveyor line 1 into the feeding module 3, an export plate group 5 arranged on the output side of the feeding module 3, a scraper 6 located at the output port of the export plate group 5, a back sheet collection box 7 located below the scraper 6, and a guide output plate 8 located on the output side of the upper part of the scraper 6.

[0032] The feeding module 3 includes a driving motor 31, an active feeding roller 32 driven to rotate by the driving motor 31, a driven feeding roller 33 arranged directly above the active feeding roller 32, and an elastic holding component 34 for pressing the driven feeding roller 33 downward. The driven feeding roller 33 and the active feeding roller 32 are arranged parallel to each other in the upper and lower directions, and a feeding port 35 for the photovoltaic module to pass through is formed between the two.

[0033] The introduction plate group 4 includes a first bottom support plate 41 and a first upper limit plate 42 located above the first bottom support plate 41. An introduction channel 43 is formed between the first bottom support plate 41 and the first upper limit plate 42. The input side of the introduction channel 43 is connected to the roller conveyor line 1, and the output side thereof is connected to the feeding port 35. The height of the introduction channel 43 gradually decreases along the material guiding direction, so as to accurately feed the photovoltaic module into the feeding port 35.

[0034] The export plate group 5 includes a second bottom support plate 51 and a second upper limit plate 52 located above the second bottom support plate 51, and an export channel 53 is formed between the second bottom support plate 51 and the second upper limit plate 52. The input side of the export channel 53 is connected to the feed port 35. The scraper 6 is located at the end of the second bottom support plate 51 and there is a gap between it and the second bottom support plate 51, and the gap forms a backplane output port 54. The backplane collection box 7 is located below the backplane output port 54 to receive the backplane stripped from the backplane output port 54. The end of the second upper limit plate 52 extends to the top of the scraper 6 and a residual material output channel 55 is formed between it and the scraper 6. The glass fragments, battery cells and metal wires left after the photovoltaic module is stripped of the backplane are bonded together by a glue material, and are output from the residual material output channel 55, and then pass through the scraper 6 and are guided to the next processing station by the guide output plate 8.

[0035] The tip of the scraper 6 is aligned with the output side of the outlet channel 53 , and the upper surface of the scraper 6 is higher than the upper surface of the second bottom support plate 51 and lower than the lower surface of the second upper limit plate 52 , so that the scraper 6 can peel off the back plate.

[0036] Since there is an error in the glass thickness of the incoming photovoltaic modules, in order to ensure that the scraper 6 can effectively and reliably peel off the back sheet, this embodiment also includes a cylinder group 9 that applies an upward pressure to the scraper 6. The piston end of the cylinder group 9 supports the two ends of the scraper 6, so that the scraper 6 is subjected to an upward force, ensuring that the scraper 6 can adaptively match the glass of different thicknesses and reliably peel off the back sheet.

[0037] The working process of the solar panel back sheet automatic peeling device 100 of the present embodiment is as follows: the photovoltaic module 200 is input through the roller conveyor line 1, the back sheet 201 is softened under the heating action of the heating module 2, and then enters the feeding port 35 through the introduction channel 43. Under the rotating feeding action of the active feeding roller 32 and the driven feeding roller 33, the photovoltaic module 200 continues to move backward and enters the export channel 53 in the export plate group 5. When the photovoltaic module 200 passes through the feeding port 35, the glass in the photovoltaic module 200 is squeezed and crushed under the squeezing action of the feeding roller, but it still maintains an integral structure due to the presence of the colloid material; In the export channel 53, the upper and lower surfaces of the photovoltaic module 200 are squeezed within a set height space. When it moves to the end, since the setting height of the scraper 6 is located in the height space of the export channel 53, the back panel 201 located on the lower surface of the photovoltaic module 200 can be scraped off. The scraped off back panel 201 is output from the bottom of the scraper 6 through the back panel output port 54 and is collected by the back panel collection box 7; and the remaining residue 202 containing glass fragments, battery cells and metal wires continues to move backward from the top of the scraper 6 through the residue output channel 55 and is finally guided to the next processing station by the guide output plate 8.

[0038] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
