Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic component recycling, and in particular to a thermal stripping device for separating photovoltaic panel glass and battery sheets. Background Art

[0002] As the global demand for renewable energy increases, the installation of solar photovoltaic panels has increased dramatically, bringing with it the problem of disposing of a large number of waste photovoltaic panels.

[0003] Photovoltaic panels are mainly composed of glass, cells (silicon-based or other), EVA (ethylene-vinyl acetate copolymer) film, backplane and metal frame, etc. Among them, glass and cells account for a relatively high proportion and have a high recycling value. The relevant technologies for separating glass from cells mainly include the combination of mechanical treatment and heat treatment technology, solvent stripping and knife separation technology after heating.

[0004] Among them, the stripping method that combines mechanical treatment with heat treatment is to soften or decompose the EVA film by mechanically crushing the photovoltaic panel and then heating it, thereby separating the glass from the battery cell. This process requires precise temperature control to avoid thermal damage to the battery cell. At the same time, it is necessary to combine physical separation technologies such as vibration screening and magnetic separation to further refine the material sorting.

[0005] Solvent stripping technology uses a specific chemical solvent to dissolve the EVA layer to achieve lossless separation of the cell and glass. This method is less efficient and requires attention to the safety of the solvent and its potential impact on the environment.

[0006] The post-heating tool separation technology usually preheats the battery cell and then uses a tool to peel off the glass. This method has low temperature control accuracy, the tool is easily damaged, the equipment occupies a large area, and the implementation cost is high.

[0007] The above methods each have certain limitations, so it is particularly important to develop low-cost, efficient and practical photovoltaic panel glass and cell separation technology. Summary of the invention

[0037] See also Figures 1 to 3As shown, the embodiment of the present application provides a thermal stripping device for separating the glass and the cell of a photovoltaic panel, which mainly includes a conveying mechanism 10 and a thermal stripping mechanism 20, wherein the photovoltaic panel includes glass and the cell attached to each other, the conveying mechanism 10 is used to carry and transfer the photovoltaic panel along the conveying direction, the conveying mechanism 10 has a stripping station, the thermal stripping mechanism 20 is arranged at the stripping station, and the glass and the cell of the photovoltaic panel are stripped by the thermal stripping mechanism 20 at the stripping station. The thermal stripping mechanism 20 includes a hot knife assembly 22, and the hot knife assembly 21 is configured to face the photovoltaic panel on the conveying plane, and is used to be inserted between the glass and the cell of the photovoltaic panel passing by to thermally separate the glass and the cell.

[0038] The hot stripping device of the present application uses a method of directly heating the cutter for hot stripping, which can ensure that the packaging material is effectively melted or softened without damaging the battery cell. Compared with the traditional method of stripping battery panels, the temperature control is more precise and the temperature range is adjustable, which improves the compactness and recycling efficiency of the equipment, reduces the recycling cost, and can also reduce the impact on the environment.

[0039] Combination Figure 2 As shown, the transport mechanism 10 of this embodiment includes a lower conveying assembly 11 and an upper conveying assembly 12. The upper conveying assembly 12 is liftably arranged relative to the lower conveying assembly 11 to clamp and transport the photovoltaic panel carried therebetween.

[0040] Specifically, the transport mechanism 10 may further include a lifting component 13, one end of the lifting component 13 is fixed to the lower conveying component 11, and the other end is fixed to the upper conveying component 12. The lifting component 13 can drive the upper conveying component 12 to rise and fall, thereby pressing the upper conveying component 12 against the photovoltaic panel.

[0041] The transport mechanism 10 may further include a bracket 100, an upper conveying assembly 12 is fixed to the bracket 100, a lower conveying assembly 11 is movably mounted on the bracket 100, and a lifting assembly 13 may be a driving source (such as a servo drive motor) or a cylinder, a hydraulic cylinder, etc. The lifting assembly 13 is fixed to the bracket 100, and a driving rod is movably connected to the upper conveying assembly 12 to drive the upper conveying assembly 12 to move up and down.

[0042] The lower conveying assembly 11 includes a lower bracket 111, a plurality of lower conveying rollers 112 and a lower driving motor 113. The lower bracket 111 is fixed to the bracket 100. The lower conveying rollers 112 are arranged side by side in the lower bracket 111. Both ends of the lower conveying rollers 112 are rotatably connected to the lower bracket 111 and rotate under the drive of the lower driving motor 113.

[0043] The upper conveying assembly 12 includes an upper bracket 121, a plurality of upper conveying rollers 122 and an upper driving motor 123. The upper conveying rollers 122 are arranged side by side in the upper bracket 121. Both ends of the upper conveying rollers 122 are rotatably connected to the upper bracket 121 and rotate under the drive of the upper driving motor 123. The driving rod of the lifting assembly 13 is connected to the upper bracket 121.

[0044] In one embodiment, the lower conveying component 11 includes a first lower conveying component 1121 and a second lower conveying component 1122. The first lower conveying component 1121 is arranged upstream of the second lower conveying component 1122. A gap G is provided between the first lower conveying component 1121 and the second lower conveying component 1122. The hot knife assembly 22 is arranged in the gap G and is spaced apart from the upper conveying component 12. The first lower conveying component 1121 is used to transport the photovoltaic panels before the battery cells are peeled off, and the second lower conveying component 1122 is used to transport the photovoltaic panels after the battery cells are peeled off.

[0045] Furthermore, the hot knife assembly 22 can be movably arranged in the interval G up and down to ensure that the hot knife assembly 22 has good contact with the glass of the photovoltaic panel. Specifically, the heat stripping mechanism 20 includes a hot knife mounting frame 21 and a hot knife assembly 22 movably mounted on the hot knife mounting frame 21 in a direction perpendicular to the conveying plane, and the hot knife assembly 22 can move relative to the hot knife mounting frame 22 to selectively approach or move away from the conveying plane.

[0046] Exemplarily, the hot stripping mechanism 20 includes a lifting mechanism 21M, such as a servo drive motor, which can be fixed to the hot knife mounting frame 21, and the driving end is connected to the hot knife assembly 22 to drive the hot knife assembly 22 to move up and down, thereby adjusting the pressing force between the hot knife assembly 22 and the glass. The lifting mechanism 21M serves as an entry adjustment mechanism for the hot knife assembly 2, so that the feed amount of the hot knife assembly 22 is controllable. By adjusting the feed speed and depth of the hot knife assembly 22, it can be ensured that the stripping process is stable and does not cause damage to the internal battery cells.

[0047] The photovoltaic panel is transported by the handling mechanism 10 to the upper conveying assembly 12 below the height-adjustable upper conveying assembly 12. The upper conveying assembly 12 can be controlled to descend by the lifting assembly 13, pressing the photovoltaic panel between the upper conveying roller 122 and the lower conveying roller 112, providing sufficient friction between the conveying rollers and the photovoltaic panel, and then the upper and lower conveying rollers are driven to rotate synchronously by the lower drive motor 113 and the upper drive motor 123 to transport the photovoltaic panel to the hot knife assembly 22 at the interval G.

[0048] When the photoelectric recognition system determines that the position of the photovoltaic panel has reached the hot knife assembly 22, the servo drive motor drives the screw lifter to raise the hot knife assembly 22 longitudinally relative to the hot knife mounting frame 21. When the hot knife assembly 22 contacts the photovoltaic panel, it moves upward for another 1-2 mm to provide sufficient pre-tightening force between the hot knife assembly 22 and the glass.

[0049] In one embodiment, the thermal stripping mechanism 20 includes a pressure sensor S, which is arranged between the mounting frame 24 and the hot knife mounting frame 21, for example, at the driving end of the lifting mechanism 21M, and is used to monitor in real time the stress condition of the knife body of the hot knife assembly 22 during operation. Once the stress exceeds the set threshold, the system can automatically adjust the working parameters or stop the operation to prevent stress overload from damaging the photovoltaic panel or the thermal stripping device.

[0050] like Figure 5 As shown, in one embodiment, the hot knife assembly 22 includes a knife body 2220, a knife seat 2221, a heating tube 2222 and a temperature sensor 2223. The knife body 2220 is arranged on the knife seat 2221, and the heating tube 2222 and the temperature sensor 2223 are arranged between the knife body 2220 and the knife seat 2221 and are in thermal contact with the knife body 2220. The heating tube 2222 is used to heat the knife body 2220, and the temperature sensor 2223 is used to detect the temperature of the knife body 2220. The system can adjust the heating power of the knife body 2220 according to the temperature of the knife body 2220 measured by the temperature sensor 2223 according to the demand.

[0051] The blade body 2220 is made of high-quality thermally conductive material and has good thermal conductivity, which can quickly transfer heat to the contact part and improve the stripping efficiency. Through the cooperation of the temperature sensor 2223 and the blade body 2220, this embodiment can adjust the temperature of the blade body 2220 (0-150°C) according to different material properties, ensuring that the packaging material is effectively melted or softened without damaging the battery cell.

[0052] The blade body 2220 is detachably connected to the blade seat 2221, so that the blade body 2220 can be quickly replaced after being worn to maintain the consistency and accuracy of the peeling effect.

[0053] In one embodiment, the hot knife assembly 22 includes a mounting frame 24, a hot knife body 222 and a hot knife adjustment mechanism 25. Both ends of the hot knife body 222 are rotatably connected to the mounting frame 24. The hot knife adjustment mechanism 25 is connected to the mounting frame 24 at one end and to the hot knife body 222 at the other end to adjust the inclination angle of the hot knife body 222.

[0054] By setting the hot knife body 222 to an adjustable tilt angle, for example, the knife body 2220 supports an angle adjustment of 0-60°, the hot knife assembly 22 can adapt to photovoltaic modules of different thicknesses, shapes and laminated structures, thereby achieving precise peeling of the cell and the glass.

[0055] Exemplarily, the hot knife assembly 22 includes a rocker arm 2224 connected to the outer periphery of the knife seat 2221, and the free end of the hot knife adjustment mechanism 25 is rotatably connected to the rocker arm 2224. The hot knife adjustment mechanism 25 can be realized by rotational adjustment, and it is rotationally connected to the mounting frame 24 by means of threads or the like. When the hot knife adjustment mechanism 25 is rotated, the hot knife adjustment mechanism 25 can push the rocker arm 2224 to make the knife seat 2221 swing relative to the mounting frame 24, thereby adjusting the inclination angle of the knife body 2220.

[0056] Before the hot knife assembly 22 cuts, the initial angle of the knife body 2220 can be adjusted by the hot knife adjustment mechanism 25. When the operator operates the hot knife adjustment mechanism 25, the swing rod 2224 drives the knife seat 2221 to rotate around the rotating shaft on the mounting frame 24, so the initial angle of the knife body 2220 will also change accordingly.

[0057] In addition, the system can also adaptively adjust the height and angle of the blade 2220 according to the data fed back by the pressure sensor S, thereby reducing the loss of the blade and improving the processing efficiency.

[0058] Specifically, in one embodiment, in order to ensure the peeling cooperation effect between the knife body 2220 and the glass, the hot knife adjustment mechanism 25 includes an adjusting member 251 and an elastic member 252. The elastic member 252 is such as a compression spring. The adjusting member 251 is movably connected to the mounting frame 24, and the elastic member 252 is connected between the adjusting member 251 and the hot knife body 222.

[0059] When the tip of the blade body 2220 is stressed, the hot knife assembly 22 will rotate counterclockwise around the rotation axis relative to the mounting frame 24, and at the same time drive the blade seat 2221 to rotate counterclockwise around its rotation axis. The elastic member 252 will be compressed, and its elastic potential energy will increase, so as to achieve the purpose of making the blade body 2220 fit the glass. Therefore, the hot knife assembly 22 of this embodiment has adaptive ability, and can increase the pressure between the blade body 2220 and the glass as the cutting resistance increases, and can also prevent the occurrence of blade jumping during the peeling process.

[0060] In addition, the hot knife body 222 can also include a bearing 2211 and a gasket 2212 on the inner side of the cover plate 221. The gasket 2212 is located between the bearing 2211 and the cover plate 221. The bearing 2211 is installed between the gasket 2212 and the knife seat 2221, so that the knife seat 2221 can rotate relative to the cover plate 221 together with the knife body 2220, and the gasket 2212 can play a dust-proof role.

[0061] Further integration Figures 6-7 As shown, in one embodiment, a cell guide channel P is provided in the hot knife assembly 22 , and the hot knife assembly 22 further includes a cell flattening mechanism 23 provided downstream of the cell guide channel P.

[0062] After the glass and the cell are peeled off, the cell is located under the glass and enters the cell guide channel P, ensuring that the glass and other materials remain flat during the cutting or peeling process. Since the peeled flexible cell is transported through the specially designed cell guide channel P and cell flattening mechanism 23, the cell curling and clogging can be avoided, ensuring that the peeled cell can enter the next process in an orderly and safe manner.

[0063] In one embodiment, the hot knife assembly 22 includes two cover plates 221 and a hot knife body 222 disposed between the two cover plates 221, and a cell guide channel P is disposed on one side of the hot knife body 222 facing the incoming direction of the photovoltaic panel. After the photovoltaic panel transmitted from the first lower conveying assembly 1121 is peeled off by the knife body 2220, the glass continues to be transmitted toward the downstream second lower conveying assembly 1122, and the cell enters the cell flattening mechanism 23 through the cell guide channel P for flattening and enters the next station.

[0064] In one embodiment, the hot knife assembly 22 includes an introduction roller 210 rotatably disposed between two cover plates 221, the introduction roller 210 and the hot knife body 222 define an entrance of the cell guide channel P, and the cell flattening mechanism 23 is connected to a side of the hot knife assembly 22 away from the transport plane. The introduction roller 210 can smoothly guide the peeled cell into the cell guide channel P.

[0065] In one embodiment, the hot knife assembly 22 may further include a lead-out roller 211 disposed downstream of the cell guide channel P, and a discharge port for conveying the cell to the cell flattening mechanism 23 is defined between the lead-out roller 211 and the cell flattening mechanism 23. After the peeled cell enters the cell guide channel P, it may be accurately guided to the cell flattening mechanism 23 at the lead-out roller 211 and between the lead-out roller 211 and the cell flattening mechanism 23.

[0066] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
