Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic panel disassembly, and in particular relates to a photovoltaic panel physical separation device and a use method thereof. Background Art

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the development and utilization of renewable energy has become the focus of attention of countries around the world. As a clean and renewable energy source, solar energy has broad application prospects. Photovoltaic panels, as key components of solar power generation, convert light energy into electricity, providing green and sustainable electricity supply for homes, businesses and public facilities. However, as a high-tech product, photovoltaic panels have a limited service life. Usually, after a long period of use, they need to be scrapped due to performance degradation, aging or damage. The treatment and recycling of scrapped photovoltaic panels is not only related to the recycling of resources and environmental protection, but also an important part of achieving sustainable development.

[0003] At present, the industry has carried out a series of research and practice on the treatment and recycling of scrapped photovoltaic panels. Among them, chemical methods and physical methods are the two main separation technologies. The chemical method mainly uses specific chemical liquids to separate the layers of materials that are stuck together (such as aluminum metal shell, glass, encapsulation film, solar cell, another layer of encapsulation film and backplane) through chemical reactions. Although this method can achieve the separation of materials, the separation speed is relatively slow, and the treatment and discharge of chemical liquids may have a certain impact on the environment. On the other hand, the physical method is to crush the photovoltaic panel into smaller particles or fragments by mechanical crushing, and then collect and utilize materials of different materials separately through screening, classification and other processes. Although this method has a faster processing speed, it is often difficult for the crushed materials to maintain their original structure and performance, so it is difficult to reuse or use them at a high value.

[0004] Although the existing chemical and physical methods have achieved certain results in the treatment and recycling of scrapped photovoltaic panels, there are still many problems and challenges. First, the chemical method has a slow separation speed and requires a long processing time, and the selection and use of chemical solutions pose certain risks to the environment and human health. Secondly, although the physical method has a fast processing speed, the quality and performance of the crushed material are greatly reduced, making it difficult to achieve high-value utilization, and the crushing process may cause dust pollution and noise pollution. Therefore, it is urgent to develop a new technology for the treatment and recycling of scrapped photovoltaic panels that can achieve fast and efficient separation, ensure the quality and performance of the material is not damaged, and reduce the impact on the environment and human health. Summary of the invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention discloses a photovoltaic panel physical separation device, comprising: a pushing component, a heating shelling component installed above the pushing component, and a removal power component installed above the heating shelling component; The heating shelling component includes a cutting portion arranged directly above the pushing component, a heating portion for heating the photovoltaic panel of the cutting portion, and a cover removing portion arranged obliquely above the pushing component; the lower portion of the cover removing portion is obliquely fixedly arranged on the side of the cutting portion; The power components are removed to contact the photovoltaic panel during rotation, and apply thrust to push the panels of different layers of the photovoltaic panel away one by one.

[0013] The present invention also discloses a method for using the photovoltaic panel physical separation device, comprising the following steps: Step S1, placing the photovoltaic panel to be removed in the placement groove of the pushing component, and the external control system passes hot air to the cutting part through the heating part; then under the control of the external control system, the push rod of the pushing component extends to drive the photovoltaic panel to approach the cutting part, and then the pushing component drives the photovoltaic panel to contact the cover removal part, compressing the cover removal part, until the pushing component drives the photovoltaic panel to separate from the cover removal part, and the pushing component stops working; Step S2, under the control of the external control system, the push rod of the pushing component contracts to drive the photovoltaic panel to approach the cover removal part, and drives the aluminum metal shell of the photovoltaic panel to contact the cover removal part. As the pushing component continues to descend, the pressure of the photovoltaic panel on the cover removal part continues to increase under the action of gravity, so that the resistance force of the cover removal part on the aluminum metal shell increases, and the aluminum metal shell is removed from the photovoltaic panel. Then the pushing component stops working again, and the photovoltaic panel is separated from the aluminum metal shell. Step S3, the external control system controls the push rod of the pushing component to extend again, driving the photovoltaic panel to continue to move upward, and then the external transport mechanism moves the aluminum metal shell away, and as the pushing component drives the photovoltaic panel to continue to rise for a distance and then stop, the removal power component starts to work, rotates and contacts the top glass of the photovoltaic panel, and as the rotational force provided by the removal power component continues to increase, the top glass is pushed away from the photovoltaic panel, and then the removal power component is reset, and the pushing component drives the photovoltaic panel to move for a distance again and then stops, and the removal power component works again, and the above process is repeated until the lower encapsulation film, solar cell, another layer of encapsulation film and the back plate are separated in turn, and the external transport mechanism takes away the separated glass, encapsulation film, solar cell, another layer of encapsulation film and the back plate in turn; Step S4: After the photovoltaic panel disassembly steps are completed, all parts are reset, and a new photovoltaic panel is placed on the pushing component again, and the above steps are repeated until the work is completed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The invention discloses a photovoltaic panel physical separation device, which integrates three main functional modules of pushing, heating shelling and removal power. Through modular design, clear division of functions and efficient coordination are achieved. Not only the overall performance of the equipment is improved, but also maintenance, upgrading and expansion are facilitated. The heating shelling component realizes effective heating and shelling of the photovoltaic panel through the cooperation of the cutting part, the heating part and the cover removal part. The heating part can provide enough heat to soften or melt the encapsulation film on the photovoltaic panel, which is convenient for subsequent separation; the cutting part is responsible for cutting the edge or specific part of the photovoltaic panel to create favorable conditions for shelling and subsequent separation; the cover removal part can easily remove the softened encapsulation film and aluminum metal shell after heating through its special position and tilt design, thereby improving the separation efficiency and accuracy. The tilt design of the cover removal part enables it to better adapt to the shape and angle of the photovoltaic panel, ensuring that the force can be applied evenly and smoothly when removing the encapsulation film and the aluminum metal shell. At the same time, it also reduces the friction and resistance that may be generated during the cover removal process, thereby improving the cover removal efficiency and the integrity of the photovoltaic panel. The removal power component can easily push different layers of the photovoltaic panel away in sequence by rotating and applying thrust. It not only improves the separation speed and efficiency, but also ensures that the layers of materials after separation maintain integrity and reusability. By adjusting the rotation speed and thrust of the removal power component, it can also adapt to the separation needs of photovoltaic panels of different types and specifications, thereby improving the versatility and flexibility of the equipment. The present invention uses a pushing component, a heating shelling component, and a removal power component in coordination with each other to produce a photovoltaic panel physical separation device to replace the traditional photovoltaic panel separation method and method, thereby achieving the effect of separating photovoltaic panels by using physical separation, ensuring that the layers of materials after separation will not become powdery, improving the separation speed, and ensuring that the various materials after separation can be reused or used in other places.

[0017] The present invention also discloses a method for using a photovoltaic panel physical separation device. The photovoltaic panel to be removed is placed on a pushing component, which provides a stable starting point for the entire disassembly process and ensures that the photovoltaic panel is correctly and safely placed on the device. The hot air can preheat the photovoltaic panel, especially the cut-off part, which helps to soften the packaging film, making the subsequent removal process easier and more efficient. Through the precise control of the pushing component, the photovoltaic panel is smoothly moved to the working position, which improves the accuracy and efficiency of the operation. The pushing component drives the photovoltaic panel to contact the cover removal part, compresses the cover removal part, and allows the cover removal part to have a certain elastic deformation when contacting the photovoltaic panel, avoiding damage that may be caused by hard contact, and also helps to better fit the shape of the photovoltaic panel. Through the reverse movement of the pushing component, the photovoltaic panel contacts the cover removal part again, preparing for the removal of the aluminum metal shell. The pressure of the photovoltaic panel on the cover removal part is increased by gravity, which helps the cover removal part to more effectively remove the aluminum metal shell. By increasing the resistance force, the aluminum metal shell is successfully removed from the photovoltaic panel. The start-up and rotation movement of the removal power component enables it to effectively contact and resist the top glass of the photovoltaic panel, providing power for the removal of the glass. By continuously increasing the rotational force, the top glass was successfully pushed off the photovoltaic panel, realizing the removal of the glass. By repeating the above process, the efficient and orderly separation of the materials of each layer of the photovoltaic panel was achieved, and the disassembly efficiency and material recovery rate were improved. Through the cyclic operation, the efficient and continuous disassembly of the photovoltaic panel was achieved, the utilization rate and production efficiency of the equipment were improved, and an effective solution for the recycling of photovoltaic panels was also provided.
