Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module recycling, and in particular to a photovoltaic module decomposition device. Background Art

[0002] In the photovoltaic industry, single-cell batteries cannot be used directly as power sources due to their fragility and poor aging resistance. Multiple cells need to be connected in series and parallel through welding strips and tightly sealed into photovoltaic modules before they can be used for a long time. Photovoltaic modules are the core components of solar power generation systems. Their function is to convert solar energy into electrical energy and send it to batteries for storage through off-grid systems, or connect to loads for work, or integrate into the power grid.

[0003] During the production process of photovoltaic modules, photovoltaic modules may be damaged and unusable due to various reasons. At this time, the damaged photovoltaic modules need to be collected and decomposed to separate the battery cells from the welding strips, and then the decomposed materials are recycled and reused by relevant departments. In the related technology, when decomposing photovoltaic modules, workers usually need to use hammers or drums to hammer or squeeze the photovoltaic modules to separate the battery cells from the welding strips. In this process, the battery cell debris may splash into the workers' eyes, and the flying powder particles may be inhaled into the lungs by the workers, causing occupational health and safety accidents. At the same time, the workers cannot completely separate the battery cells from the welding strips, and there is a partial adhesion phenomenon, which results in poor recycling effect.

[0036] An embodiment of the present application provides a photovoltaic module disassembly device for disassembling a photovoltaic module, forcing the cell and the soldering ribbon of the photovoltaic module to be separated, so as to recycle the cell and the soldering ribbon respectively. Figures 1 to 3 The photovoltaic module disassembly device of one embodiment includes a squeezing box 10, an impact box 20, a transfer mechanism 40 and a suction mechanism 30, wherein the squeezing box 10 is provided with an squeezing chamber 111 and a feeding port 112 connected to the squeezing chamber 111, and the squeezing chamber 111 is provided with an squeezing mechanism 12 for squeezing photovoltaic modules. The impact box 20 is provided with an impact chamber 211 and a suction port 212 connected to the impact chamber 211, and the impact chamber 211 is provided with an impact mechanism 22 for impacting photovoltaic modules. The transfer mechanism 40 is used to receive the squeezing photovoltaic modules in the squeezing chamber 111 and transfer the squeezing photovoltaic modules to the impact chamber 211. The suction port of the suction mechanism 30 is connected to the suction port 212.

[0037] When the photovoltaic module separation device is working, the photovoltaic module to be decomposed can be sent into the extrusion chamber 111 through the feeding port 112 of the extrusion box 10, and then the extrusion mechanism 12 in the extrusion chamber 111 squeezes the photovoltaic module. Since the cell of the photovoltaic module is fragile, and the welding strip has a certain toughness, the photovoltaic module will form cell fragments and welding strips after being squeezed by the extrusion mechanism 12. At the same time, the cell fragments and welding strips fall onto the transfer mechanism 40, thereby achieving the initial separation of the cell and the welding strip. Then, the cell fragments and welding strips are transferred to the impact chamber 211 through the transfer mechanism 40. The impact mechanism 22 in the impact chamber 211 can impact the cell fragments and welding strips, thereby further crushing the cell fragments and making the cell fragments adhered to the welding strip fall off completely. Finally, the suction mechanism 30 opens the negative pressure to extract the cell slag formed after the cell fragments are crushed out of the impact chamber 211, while the welding strips remain on the transfer mechanism 40, thereby achieving the complete separation of the cell and the welding strip. Compared with the traditional manual separation scheme, the photovoltaic module separation device of the present application first squeezes the photovoltaic module through the squeezing mechanism 12, and then impacts the photovoltaic module through the impact mechanism 22, so as to completely crush the battery cell, avoid the adhesion of the battery cell fragments and the welding belt, ensure the complete separation of the battery cell and the welding belt, and improve the recycling efficiency and recycling quality of the photovoltaic module. At the same time, the squeezing and impacting of the photovoltaic module are respectively carried out in the closed squeezing box 10 and the impact box 20, and the battery cell slag formed after decomposition is directly sucked away by the suction mechanism 30, avoiding the splashing of the battery cell slag to harm the personal safety of the workers, and improving the safety performance.

[0038] Optionally, in one embodiment, the extrusion mechanism 12 includes a driving member and a plurality of meshing extrusion gears, the driving member is connected to one of the extrusion gears to drive the extrusion gear to rotate, and an extrusion channel for extruding the photovoltaic module is formed between the two meshing extrusion gears. In this way, the driving member drives the extrusion gear to rotate, and after the photovoltaic module is placed into the extrusion channel from the feeding port 112, the photovoltaic module will be squeezed from both sides by the two meshing extrusion gears, so that the battery cell is broken and separated from the welding ribbon.

[0039] Specifically, see Figure 1In a specific embodiment, the number of extrusion gears is three, and the three extrusion gears are respectively a driving wheel 121, a driven wheel 122 and an auxiliary wheel 123. The driving member is connected to the driving wheel 121, and the driven wheel 122 is meshed with the driving wheel 121. A first extrusion channel 126 for extruding photovoltaic components is formed between the driven wheel 122 and the driving wheel 121. The entrance of the first extrusion channel 126 faces the feeding port 112. Further, the entrance of the first extrusion channel 126 is located below the feeding port 112. In this way, after the photovoltaic component is thrown into the feeding port 112, it will directly fall into the entrance of the first extrusion channel 126, and then the driving member drives the driving wheel 121. Driven by the driving wheel 121 and the driven wheel 122, the photovoltaic component can enter the first extrusion channel 126 and be crushed by the driving wheel 121 and the driven wheel 122.

[0040] Furthermore, the auxiliary wheel 123 is disposed at the exit of the first extrusion channel 126, and the auxiliary wheel 123 is meshed with the driven wheel 122, and a second extrusion channel 127 for extruding the photovoltaic module is formed between the auxiliary wheel 123 and the driven wheel 122. In this way, the photovoltaic module can directly fall onto the auxiliary wheel 123 after being extruded once in the first extrusion channel 126, and enter the second extrusion channel 127 driven by the auxiliary wheel 123 for secondary extrusion, thereby further crushing the battery sheet.

[0041] It is worth noting that in other embodiments, the auxiliary wheel 123 may also be engaged with the driving wheel 121, so that a second extrusion channel 127 for extruding the photovoltaic module is formed between the auxiliary wheel 123 and the driving wheel 121, thereby achieving secondary extrusion of the photovoltaic module.

[0042] Optionally, in one embodiment, the driving member includes a motor 124, and the output shaft of the motor 124 is connected to the driving wheel 121, so that the driving wheel 121 can be automatically driven by the motor 124, saving time and effort. In another embodiment, the driving member may also include a crank handle 125, and the crank handle 125 is connected to the driving wheel 121, so that the driving wheel 121 can also be manually rotated by the crank handle 125, thereby saving energy consumption. Understandably, in one embodiment, the driving member may also include a motor 124 and a crank handle 125 at the same time, and the motor 124 and the crank handle 125 are both connected to the driving wheel 121, so that the driving wheel 121 is rotated by the crank handle 125, and the motor 124 drives the driving wheel 121 as an auxiliary power, saving effort and saving energy consumption.

[0043] It is worth noting that there are many ways to achieve the extrusion of photovoltaic components, which are not limited to the above-mentioned form of using extrusion gears. For example, in other embodiments, the photovoltaic components can also be rolled by rollers to crush the photovoltaic components.

[0044] See also Figure 1In one embodiment, the impact mechanism 22 includes an electric cylinder 221 and an impact seat 222 connected to the electric cylinder 221. The electric cylinder 221 is used to drive the impact seat 222 to move closer to or away from the transfer mechanism 40 entering the impact cavity 211, thereby hammering the battery cell fragments and the welding ribbon on the transfer mechanism 40, thereby further crushing the battery cell fragments and completely falling off the battery cell fragments adhered to the welding ribbon.

[0045] Furthermore, the impact seat 222 is made of an elastic material, for example, the impact seat 222 is made of a woolen material or a silicone material, so as to prevent the impact seat 222 from crushing the transfer mechanism 40 when impacting the photovoltaic component.

[0046] It is worth mentioning that there are many ways to impact photovoltaic modules, not limited to the above-mentioned method of using the electric cylinder 221 to drive the impact seat 222. For example, in other embodiments, the photovoltaic module can also be impacted by an electric push rod or a screw mechanism, which can also further crush the battery cell fragments and completely remove the battery cell fragments adhered to the welding strip.

[0047] See also Figure 1 In one embodiment, the transfer mechanism 40 includes a tray 41 and a walking member 42 connected to the tray 41, the tray 41 is used to carry the photovoltaic module, and the walking member 42 is used to drive the tray 41 to transfer between the extrusion box 10 and the impact box 20. Preferably, in one embodiment, the walking member 42 is a wheel, and it is more convenient and labor-saving to transfer the tray 41 using the wheel. Understandably, in another embodiment, the walking member 42 can also be a conveyor belt, and the tray 41 is automatically transferred by the conveyor belt, which is more convenient and labor-saving.

[0048] Furthermore, in one embodiment, the squeezing box 10 is provided with a first slot (not shown) connected to the squeezing chamber 111, and the tray 41 is detachably arranged in the first slot, so that after the photovoltaic module is squeezed by the squeezing mechanism 12 and falls into the tray 41, the tray 41 together with the squeezed photovoltaic module can be directly extracted from the squeezing box 10 and transferred to the impact box 20. Further, the impact box 20 is provided with a second slot (not shown) connected to the impact chamber 211, and the tray 41 is detachably arranged in the second slot, so that the tray 41 extracted from the squeezing box 10 can be directly inserted into the second slot to send the squeezed photovoltaic module into the impact chamber 211 for impact, and after the impact is completed and the suction mechanism 30 extracts the battery cell debris, the tray 41 can be extracted from the second slot together with the welding strip, thereby realizing the recovery of the welding strip.

[0049] See also Figure 1In one embodiment, the suction mechanism 30 includes a vacuum cleaner 31 and a vacuum pipe 32. One end of the vacuum pipe 32 is connected to the vacuum cleaner 31, and the other end of the vacuum pipe 32 forms a suction port and is connected to the suction port 212. In this way, the vacuum cleaner provides negative pressure, and the battery cell debris can enter the dust collecting chamber of the vacuum cleaner 31 through the vacuum pipe 32, thereby realizing the recovery of the battery cell debris.

[0050] Furthermore, a filter 33 for isolating the solder strip is provided near the suction port of the dust suction pipe 32, thereby preventing the solder strip from being sucked into the dust collector 31. In one embodiment, the mesh size of the filter 33 is 10mm*10mm, thereby preventing the solder strip from clogging the mesh of the filter 33.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
