[0027] The reference signs in the drawings of the specification include: photovoltaic laminate 1, xenon lamp irradiation module 2, and xenon lamp 3. DETAILED DESCRIPTION

[0028] The following will be further described in detail through specific embodiments: EMBODIMENT The photovoltaic module is designed as a multi-layer stack, and the structure of the photovoltaic module is from top to bottom, one side of which is a glass cover plate, an upper EVA adhesive film, a cell string, a lower EVA adhesive film and a back plate. The outer periphery of the photovoltaic layer is provided with an aluminum alloy frame which is bonded with the glass and the back plate edge through silicone or double-sided tape to provide mechanical support and prevent the deformation of the module. The back plate of the photovoltaic module is provided with a junction box, and a bypass diode is arranged in the junction box to prevent hot spot effect, and an output cable is connected to an inverter.

[0029] The back plate of the photovoltaic module includes a fluorine-containing back plate and a non-fluorine back plate; the fluorine-containing back plate such as TPT (polyvinyl fluoride composite film) and KPK (polyvinyl fluoride / polyester / polyvinyl fluoride) has excellent weather resistance and ultraviolet resistance. The non-fluorine back plate such as PET / aluminum / PET composite film has lower cost, but the weather resistance is slightly poor. The fluorine-containing back plate is irradiated with strong energy light, which will cause the fluorine-containing back plate to break and decompose to produce toxic gas.

[0030] In order to avoid the pollution of the photovoltaic module separation and recovery and improve the recovery efficiency, the embodiment provides the following method.

[0031] As shown in the accompanying Figure 1 A non-destructive photovoltaic module separation method, comprising the following steps: The photovoltaic module is cleaned to ensure that the glass surface of the photovoltaic module has no shielding area; the junction box and the frame of the photovoltaic module are removed, and a photovoltaic laminated part can be obtained; The xenon lamp irradiation module is arranged vertically and parallel to the photovoltaic laminated part, and the xenon lamps in the xenon lamp irradiation module are arranged along the length direction of the photovoltaic laminated part, on one side of the glass surface of the photovoltaic laminated part, facing the xenon lamp irradiation module; The photovoltaic laminated part is irradiated and separated for the first time by the xenon lamp irradiation module, and the back plate and the EVA adhesive film adjacent to the back plate and the copper-tin solder strip are peeled off; The photovoltaic laminated part with the peeled-off back plate is irradiated for the second time, the adhesion of the EVA adhesive film adjacent to the glass layer is destroyed, and the impact wave of the instantaneous light released by the xenon lamp makes the cell sheet move transversely, so that the cell layer is automatically separated from the photovoltaic layer and falls down, and a clean cell layer is obtained; The EVA adhesive film adjacent to the glass is peeled off, and clean and complete glass is obtained.

[0032] The waste photovoltaic module is disassembled by physical and optical methods, the material layers of the photovoltaic module are separated, the photovoltaic module is irradiated twice, the energy released in one-time irradiation is avoided to be too large, and the fluorine-containing material layer of the back plate is prevented from decomposing.

[0033] As shown in the accompanying Figure 2As shown, a group of xenon lamp irradiation modules 2 can irradiate two groups of photovoltaic laminates 1 simultaneously, the xenon lamp irradiation modules 2 are located between the two groups of photovoltaic laminates 1, and the two photovoltaic laminates are irradiated synchronously, thereby greatly improving the working efficiency of the xenon lamp irradiation photovoltaic assembly. The two photovoltaic assemblies to be irradiated are symmetrically fixed during the whole separation process, and the distance is 100mm-1000mm.

[0034] The xenon lamp irradiation module can be selected for fractionated irradiation according to the needs. The photovoltaic assembly with fluorine back plate can be irradiated twice, and the charging time of the two xenon lamp modules is between 3-120s, and the xenon lamp power is between ; By controlling the charging time of the xenon lamp module, the irradiation energy intensity of the xenon lamp module is controlled. The photovoltaic assembly without fluorine back plate or without back plate can be irradiated once.

[0035] The xenon lamp irradiation module is vertically arranged to perform the first xenon lamp irradiation and the second xenon lamp irradiation on the photovoltaic laminate. As shown in FIGS. 1 and 2, the xenon lamp irradiation module 2 includes a plurality of groups of xenon lamps 3, which can be set according to the size or needs of the photovoltaic laminate 1. Figure 2 Figure 3 As shown in FIGS. 1 and 2, the xenon lamp irradiation module 2 includes a plurality of groups of xenon lamps 3, which can be set according to the size or needs of the photovoltaic laminate 1.

[0036] When the xenon lamp irradiation module is running, the plasma recoil force generated by the gas discharge, the external vibration and the transverse moment caused by the uneven thermal expansion will cause the electrode to vibrate. In the traditional xenon lamp irradiation module, the lamp tube is often arranged horizontally, which makes the moment easy to cause the electrode to deviate or vibrate, affecting the stability of the system. In the vertical state of the xenon lamp irradiation module, the electrode axis is consistent with the direction of gravity, and the gravity directly offsets the lateral disturbance, so that the electrode remains stable in the axial direction and reduces the risk of deviation.

[0037] The first xenon lamp irradiation is to strip the back plate and the EVA film adjacent to the copper-tin solder strip, and the second xenon lamp irradiation is to use the shock wave of light to realize the complete automatic separation of the battery piece and the EVA film adjacent to the glass, and further damage the adhesion performance of the glass layer and the EVA film adjacent to the glass.

[0038] When cleaning the photovoltaic assembly, a plurality of brushes can be arranged between the two photovoltaic assemblies to clean the glass surface of the photovoltaic assembly.

[0039] ​The photovoltaic laminates to be irradiated are fixed by using an irradiation fixing piece in the xenon lamp irradiation module, the irradiation fixing piece uses a fixing mode of cooperation of a clamping groove and a spring, the fixed position of the photovoltaic laminates is defined by the clamping groove, and the photovoltaic laminates are pressed against the clamping groove by the spring to realize temporary fixing, for example, the spring is arranged in the clamping groove and located on the side of the photovoltaic laminates away from the xenon lamp irradiation module. The spring can also control the distance between the photovoltaic laminates and the xenon lamp irradiation module. The spring and the clamping groove adjacent to the side of the xenon lamp irradiation module are made of high-strength light-transmitting material to avoid causing irradiation shielding. The irradiation fixing piece can adjust the fixed position according to the size of the photovoltaic module to adapt to photovoltaic modules of different specifications.

[0040] In order to facilitate the collection of the battery pieces, a collecting piece for collecting the battery pieces is arranged on the side of the xenon lamp irradiation unit corresponding to the horizontal side moving direction of the battery.

[0041] When the xenon lamp irradiates, high-voltage arc excites xenon gas to generate instantaneous strong light, and high-energy photons interact with the material to form a shock wave in the photovoltaic module. Due to the impedance difference at the interface between the battery piece and the EVA layer, such as the difference in material density and elastic modulus, the shock wave is reflected and refracted, causing lateral stress concentration and pushing the battery piece to move in a direction parallel to the surface of the module. The vertically arranged xenon lamp is parallel to the module, so that the shock wave energy is uniformly distributed along the axial direction, enhancing the lateral thrust effect. Under the action of gravity, the battery pieces fall downward to automatically collect the battery pieces.

[0042] The xenon lamp is arranged vertically perpendicular to the ground, which can prolong the service life of the xenon lamp and enhance the light uniformity during xenon lamp irradiation, realize complete separation of the battery piece and the EVA layer, simultaneously irradiate multiple photovoltaic modules, and use the light shock wave generated during xenon lamp irradiation to make the battery piece automatically fall in a specific area under the action of lateral thrust and gravity, so that it is not necessary to flip the module and clean and collect the battery pieces after irradiation. At the same time, it is convenient for real-time monitoring, timely discovery of problems and maintenance.

[0043] The present application uses physical and optical methods to cooperatively disassemble waste photovoltaic modules, provides a method for disassembling scrapped photovoltaic modules, and obtains clean battery pieces, high metal recovery rate and high recovery purity, which is convenient for subsequent resource utilization. The whole process line has the advantages of low energy consumption, greatly improved processing capacity, no waste gas and waste liquid generation, etc. At the same time, the service life of the xenon lamp is longer, the irradiation effect is better, and the cost is lower.

[0044] The present embodiment also provides a non-destructive photovoltaic module separation system, which comprises: The full-automatic cleaning device is located on the side of the photovoltaic module away from the xenon lamp and cleans the surface of the photovoltaic module to remove the shielding objects (such as floating dust), so as to ensure that the light shock wave of the xenon lamp uniformly penetrates and improves the EVA layer peeling effect.

[0045] The photovoltaic module leading end dismounting device is integrated in the system process, adjacent to the cleaning device, and removes the junction box and aluminum frame to obtain a complete photovoltaic laminate, a glass-EVA-cell-EVA-backboard structure, and prepares for subsequent processing.

[0046] The fixed and precise positioning device adopts a "clamping groove + spring" design. The clamping groove adjacent to the xenon lamp is made of high-strength light-transmitting material, which fixes the laminate and precisely positions it, ensuring the stability of the photovoltaic module position during xenon lamp irradiation.

[0047] The xenon lamp irradiation module is vertically arranged between two photovoltaic modules and can irradiate two photovoltaic modules simultaneously to generate a light shock wave to separate the materials. For a fluorine-containing backboard module, the first irradiation separates the backboard and the adjacent EVA, and the second irradiation separates the cell and the glass adjacent EVA. For a double-glass module, the irradiation can be performed at one time, improving the light utilization efficiency.

[0048] The stripping device is located behind the xenon lamp module and uses rollers and suction cups for transportation, stripping, and collecting each material layer to achieve automatic classification and recycling.

[0049] The collection piece is located on the side of the xenon lamp irradiation module and is used to collect the detached cells. The cells automatically fall into the collection piece under the transverse thrust of the shock wave and the action of gravity, achieving automatic recycling without flipping.

[0050] The photovoltaic modules enter the cleaning, dismounting, irradiation, and stripping processes in sequence through the conveying belt, which is automatically controlled throughout the process. The conveying belt is made of polyurethane or anti-static PVC.

[0051] The xenon lamp irradiation module and the stripping device are connected through rollers and suction cups to ensure that the module quickly enters the stripping stage after irradiation, reducing the processing time.

[0052] In the photovoltaic module leading end dismounting device and the stripping device, the photovoltaic module is fixed by arranging a group of suction cups or more on the glass surface of the two photovoltaic modules. Each group has at least two suction cups, the distance between adjacent suction cups in the same group is adjustable, and the glass surfaces of the two symmetric photovoltaic modules are connected by suction cups at the same cross-section, i.e., at the same horizontal height, to ensure that the forces on the suction cups on both sides are evenly distributed and the stability of the fixation is improved.

[0053] A remote computer monitors the status of each device in real time, such as irradiation parameters and stripping progress, automatically adjusts the charging time of the xenon lamp, and adapts to photovoltaic modules of different sizes and models.

[0054] The split irradiation strategy avoids high-temperature decomposition of the fluorine-containing backboard and reduces toxic gas emissions. The light shock wave does not cause chemical corrosion, and no waste liquid is generated.

[0055] The above-mentioned are only embodiments of the present application, and common technical solutions and / or common knowledge of the scheme are not described in detail. It should be pointed out that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the patent.
