Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] As the photovoltaic industry expands, the disposal of scrapped photovoltaic solar cells has become a crucial step. Currently, there are two main methods: one is manual crushing using rubber hammers, which results in flying debris and dust pollution. The other is automated crushing equipment, but this equipment has high procurement, installation, and maintenance costs and occupies a large space.

[0024] In this embodiment of the application, the first direction is Figure 1 The Y direction is shown, and the second direction is... Figure 1 The X direction is shown, and the height direction is... Figure 1 The Z direction is shown.

[0025] Please see Figure 1To address the aforementioned issues, this application provides a photovoltaic (PV) cell string processing and recycling device 100. The PV cell string processing and recycling device 100 includes a processing component 1 and a recycling component 2. The processing component 1 includes a support member 11 and a rolling member 12, the rolling member 12 being rotatably connected to the support member 11. The recycling component 2 includes a collection body 21, which has a receiving cavity 211 and an opening 212 communicating with the receiving cavity 211. The receiving cavity 211 extends at least along a first direction, intersecting the rolling axis of the rolling member 12. The receiving cavity 211 is used to receive the rolling member 12, allowing the rolling member 12 to roll along the first direction. In use, the PV cell string processing and recycling device 100 places the discarded PV solar cells to be processed into the opening 212 of the collection body 21. The support member 11 supports the rolling member 12, which rolls back and forth in the receiving cavity 211 of the collection body 21 along the first direction, causing the rolling member 12 to crush the PV solar cells. Therefore, the crushing process of the photovoltaic solar cells takes place in the receiving cavity 211 of the collection body 21. The cavity wall of the receiving cavity 211 can reduce the splashing of fragments and prevent dust from scattering during the crushing process. In addition, the photovoltaic solar cells can be crushed by setting the support member 11, the rolling member 12 and the collection body 21. The structure is compact and has low structural complexity, which can reduce the cost of use and the space occupied.

[0026] First, the specific structure of the processing component 1 in the embodiments of this application will be introduced.

[0027] Please see Figure 2 In optional embodiments, the support member 11 may be a support rod or a support plate, etc. The embodiments of this application do not limit the specific form of the support member 11. Any shape and structure that can support the rotation of the rolling member 12 is within the protection scope of the embodiments of this application.

[0028] In an optional embodiment, the rolling element 12 may be a roller or a wheel. Both rollers and wheels can be rotatably connected to the support element 11 via bearings.

[0029] In an optional embodiment, the rolling element 12 and the support element 11 may be made of ultra-high molecular weight polyethylene or steel, etc.

[0030] Please see Figure 2 In some embodiments, the surface of the rolling element 12 is provided with protrusions 121. The tips or edges of the protrusions 121 can form stress concentration points. When the rolling element 12 rotates, local high pressure is generated at the moment the protrusions 121 come into contact with the photovoltaic solar cell, causing the photovoltaic solar cell to crack due to stress exceeding its strength limit. The protrusions 121 can concentrate the crushing force on a smaller area, shorten the crushing time, and improve the crushing efficiency.

[0031] Please see Figure 2In optional embodiments, the shape of the protrusion 121 can be a toothed protrusion, a prismatic protrusion, a conical protrusion, a corrugated protrusion, etc. The specific shape of the protrusion 121 is not limited in the embodiments of this application. For example, it can be a triangular tooth, a trapezoidal tooth, a semi-circular arc tooth, etc.

[0032] Preferably, in some embodiments, the protrusion 121 has a serrated structure. The serrated structure has a pointed tip and sharp edges. When the rolling element 12 rotates, the tip of the serrated structure contacts the photovoltaic solar cell first, concentrating the crushing force on a very small area, generating high local stress, causing the photovoltaic solar cell to break rapidly, thus improving the crushing efficiency.

[0033] In optional embodiments, the protrusions 121 include multiple protrusions, which can be arranged in an array or a spiral pattern on the rolling surface of the rolling element 12. This application does not limit the specific arrangement of the protrusions 121.

[0034] The specific structure of the recycling component 2 in this embodiment will be described in detail below.

[0035] Please see Figure 1 In optional embodiments, the shape of the collecting body 21 may be a cuboid, cylinder, or ellipse. The specific shape of the collecting body 21 is not limited in the embodiments of this application.

[0036] In an optional embodiment, the material of the collecting body 21 may be ultra-high molecular weight polyethylene or steel, etc.

[0037] Please see Figure 1 In an optional embodiment, the receiving cavity 211 extends at least along a first direction. It is understood that the receiving cavity 211 may also extend along other directions, such as a second direction, which can expand the rolling direction and rolling area of ​​the rolling element 12. Thus, the rolling element 12 can not only roll along the first direction, but also roll along other directions, thereby increasing the breaking area of ​​the rolling element 12.

[0038] In an optional embodiment, the opening 212 may be provided on the top, side or bottom of the collecting body 21. The present application embodiment does not limit the location of the opening 212.

[0039] Please see Figure 1 To facilitate manual operation of the support 11 to roll the rolling element 12, an opening 212 is provided on the top wall 213 of the collecting body 21. (See also...) Figure 1In some embodiments, the collecting body 21 includes a bottom wall 214 and a side wall 215. The side wall 215 has an opening 212 formed at its top along its height direction, and the bottom wall 214 is connected to the bottom of the side wall 215 along its height direction to form a receiving cavity 211. The bottom wall 214 extends at least along a first direction. The opening 212 is located on the top wall 213 of the collecting body 21, allowing for easy manual operation of the rolling element 12 to roll and crush the photovoltaic solar cells. Furthermore, the receiving cavity 211 is enclosed by the side wall 215, further increasing the blocking area and reducing debris splashing and dust scattering, facilitating debris recovery.

[0040] Please see Figure 1 In some embodiments, the collecting body 21 further includes a top wall 213, which is connected to the top of the side wall 215 along its height direction and covers the opening 212. The top wall 213 also has a movable groove 2131 communicating with the receiving cavity 211. The movable groove 2131 extends at least along a first direction, and the area of ​​the movable groove 2131 is smaller than the area of ​​the opening 212. The movable groove 2131 is used for the support member 11 to pass through. The addition of the top wall 213 to the collecting body 21 further increases the blocking area and further reduces the diffusion of debris and dust. The movable groove 2131 on the top wall 213 can avoid the movement of the support member 11.

[0041] Please see Figure 1 In some embodiments, the top wall 213 is made of a transparent material, which makes it easy to observe the breakage of the photovoltaic solar cells by the rolling element 12.

[0042] In an optional embodiment, the top wall 213 may be made of polymethyl methacrylate, polycarbonate, polystyrene, etc.

[0043] Please see Figure 1 In some embodiments, the recycling assembly 2 further includes a separator 22 disposed within the receiving cavity 211 to divide the receiving cavity 211 into a first receiving cavity 2111 and a second receiving cavity 2112. The separator 22 has a communication structure 221 that communicates with both the first receiving cavity 2111 and the second receiving cavity 2112. The first receiving cavity 2111 communicates with the opening 212 and extends at least along a first direction. The first receiving cavity 2111 is used to receive the rolling element 12. The first receiving cavity 2111 is used to crush the photovoltaic solar cells, and the crushed fragments enter the second receiving cavity 2112 through the communication structure 221 for collection. Thus, the recycling assembly 2 integrates crushing and collection.

[0044] Please see Figure 1In an optional embodiment, the first receiving cavity 2111 and the second receiving cavity 2112 may be distributed within the collecting body 21 along a first direction. Alternatively, the first receiving cavity 2111 and the second receiving cavity 2112 may be distributed along the height direction of the collecting body 21. The embodiments of this application do not limit the location of the first receiving cavity 2111 and the second receiving cavity 2112.

[0045] Please see Figure 1 In some embodiments, along the height direction of the collecting body 21, the first receiving cavity 2111 is located at the top of the second receiving cavity 2112. Thus, fragments broken in the first receiving cavity 2111 can fall directly into the bottom second receiving cavity 2112 by gravity, which can accelerate the fragment collection speed.

[0046] Please see Figure 1 In an optional embodiment, the connecting structure 221 may be a through hole or a through groove, etc.

[0047] Please see Figure 1 In some embodiments, the connecting structure 221 is a through groove that extends along a second direction and intersects with the first direction. The through groove extending along the second direction increases the opening area of ​​the through groove, facilitating the falling of fragments, while simultaneously preventing interference with the rolling motion of the rolling element 12 along the first direction.

[0048] Please see Figure 1 In some embodiments, the connecting structure 221 includes multiple interconnecting structures 221, which are spaced apart and arrayed on the separator 22. The presence of multiple interconnecting structures 221 increases the drop area and improves the debris collection rate. The spaced apart array of multiple interconnecting structures 221 on the separator 22 ensures uniform drop and prevents excessive accumulation of debris in any particular area.

[0049] Please see Figure 1 Therefore, the photovoltaic cell string processing and recycling device 100 provided in this application embodiment has a simple structure, low manufacturing cost, and can integrate crushing and collection in a synchronized and integrated manner. While crushing photovoltaic solar cells, it can collect fragments, greatly improving the fragment processing efficiency. In addition, the structure of the collection body 21 provided in this application embodiment, by setting the bottom wall 214, side wall 215 and top wall 213, greatly reduces the problems of fragment splashing and dust diffusion.
