Description

Technical Field

[0001] The invention belongs to the technical field of product recycling equipment, and in particular relates to a device with a clamping and heating function for multi-layer bonding products. Background Art

[0002] Multi-layer bonded products, such as laminated glass and solar panels, play an important role in enhancing product performance and durability due to their complex structure and diverse materials. These products usually use a combination of multiple layers of materials, and use advanced bonding technology to achieve close bonding of each layer of materials. However, this structural complexity also brings technical difficulties in recycling and separation. Traditional separation methods are often inefficient and difficult to adapt to the growing environmental protection requirements and resource recovery needs.

[0003] At present, there are many deficiencies in the separation and recycling technology of multi-layer bonded products such as solar panels and laminated glass. For example, direct incineration methods will produce harmful gases and cause serious pollution to the environment; while physical grinding or chemical treatment may damage the reuse value of materials. In addition, the existing technology has high energy consumption during the processing process, and the separation efficiency and purity are unsatisfactory, which is difficult to meet the modern recycling industry's demand for efficient, environmentally friendly and low-cost solutions.

[0004] In view of the limitations of the prior art, the prior application of the present invention (application number 2024107151646) proposes a method for separating and recovering multilayer bonded products. This method uses the extrusion force to generate stress concentration at the bonding interface through a pre-crushing step, thereby achieving more efficient material separation. Subsequently, by heating to a specific temperature, the principle of thermal expansion is used to loosen the fragments or particles from the adhered polymer material. This method not only improves the separation efficiency, but also reduces environmental pollution and material damage. Further, the fragments or particles are targeted to fall off the polymer material by using point-shaped objects and / or point contact striking.

[0005] This delicate operation improves the efficiency and purity of separation, providing a more environmentally friendly and efficient solution for the recycling of multi-layer bonded products. In this way, high-purity recycling of materials can be achieved, contributing to the recycling of resources and sustainable development.

[0006] However, there is no complete set of equipment for realizing the above-mentioned clamping and heating functions of multi-layer adhesive products in the prior art. Therefore, it is very urgent to develop supporting equipment for separating and recycling multi-layer adhesive products. Summary of the invention

[0007] The purpose of the present invention is to provide a device with a clamping and heating function for multi-layer bonded products, so as to solve a series of problems existing in the separation and recycling of existing multi-layer bonded products such as solar panels.

[0008] The complete technical solution of the present invention is as follows:

[0009] A clamping and heating functional device for a multi-layer bonded product, wherein the multi-layer bonded product has a structure formed by a polymer material that can be crushed or hit by sandwich bonding or single-sided bonding, and the device comprises at least one of the following components or a combination thereof:

[0010] A clamping and conveying assembly, used for clamping the multi-layer bonding product and conveying it in a predetermined direction;

[0011] A heating source, used to heat the multi-layer bonded product during clamping and conveying;

[0012] A power source is used to drive the clamping and conveying component.

[0013] The core of the above solutions is the integration of key components such as clamping and conveying, heating and power drive. This integrated design significantly improves the processing capacity and operating efficiency of the equipment. The clamping and conveying components ensure the stability and conveying efficiency of multi-layer bonded products during the processing. The introduction of the heating source uses thermal energy to further promote material separation, improving the thoroughness and efficiency of separation. The power source ensures the smoothness and reliability of the operation of the entire equipment. Overall, the above solutions achieve efficient, stable and continuous clamping, conveying and heating of multi-layer bonded products.

[0014] As a further preferred embodiment, the clamping and conveying assembly comprises at least a plurality of first components whose main parts are cylindrical and are arranged in a row or / and in a row, and a plurality of second components whose main parts are cylindrical and are arranged in a row or / and in a row; and

[0015] The first component and the second component clamp the multi-layer bonded product; and

[0016] The first component and the second component clamp and convey the multi-layer bonded product in press contact with the first component and the second component in a predetermined direction through the rotation of the cylindrical structures.

[0017] The present invention realizes the clamping and conveying of multi-layer adhesive products by means of a plurality of cylindrical first components and second components placed in a row or continuously. This design not only improves the clamping stability and the conveying continuity, but also realizes the efficient clamping and conveying of products by means of the rotation of the cylindrical structure.

[0018] As a further preferred solution, the first component and / or the second component is provided with a concave-convex structure of a cylindrical portion; the concave-convex structures on adjacent first components or second components engage with each other to prevent the clamped multi-layer bonded product from curling in the vertical direction.

[0019] Furthermore, the multi-layer bonded product includes a product whose surface has been broken or pre-broken, such as a naturally broken product, an artificially broken product, or a pre-broken product.

[0020] As a further preferred embodiment, it further comprises a crushing assembly, wherein the crushing assembly comprises one or more striking members;

[0021] Preferably, the striking member includes but is not limited to a hammer member, a cutting member, a friction member or a stirring member.

[0022] The present invention adopts a variety of striking component designs, which provides flexibility for processing different types of multi-layer bonded products. The appropriate striking method can be selected according to the product characteristics to achieve a more accurate and effective crushing effect. Such a design significantly improves the adaptability and crushing efficiency of the equipment, and helps to achieve higher quality material separation and recycling.

[0023] As a further preferred solution, the clamping and conveying assembly further comprises a chain transmission mechanism provided at one end or both ends of the first component and / or the second component; the power source comprises a motor, at least for driving the chain transmission mechanism;

[0024] Preferably, the chain transmission mechanism includes but is not limited to a transmission mechanism constructed based on one or a combination of gear transmission, belt transmission, chain transmission, friction wheel transmission, worm gear transmission, roller chain transmission, wire rope transmission, synchronous belt transmission.

[0025] By arranging a chain transmission mechanism at one or both ends of the first component and / or the second component, efficient power transmission of the clamping and conveying assembly is achieved. The introduction of the chain transmission mechanism, including but not limited to various transmission methods such as gear transmission, belt transmission, and chain transmission, provides a variety of power transmission solutions for the equipment, and the most suitable transmission mechanism can be selected according to actual application requirements.

[0026] In particular, the design of the driving wheel and the driven wheel realizes the effective driving of the first component and the second component through the staggered meshing of adjacent components, thereby improving the stability and reliability of the clamping and conveying. In addition, the configuration of the motor as the power source ensures the efficient operation of the entire transmission mechanism, thereby improving the working efficiency and performance of the entire equipment.

[0027] Preferably, the chain transmission mechanism comprises, based on a gear transmission structure:

[0028] A driving wheel, used to directly drive the first component or the second component to rotate, and indirectly drive the corresponding second component or the first component to rotate;

[0029] The driven wheel cannot directly drive the first component or the second component to rotate, but is used to drive the next adjacent driving wheel to rotate;

[0030] The driving wheel and the driven wheel are staggeredly engaged on one side or both sides of the adjacent first component and / or second component;

[0031] Preferably, the driving wheel is connected to the first component and / or the second component concentrically without differential, and the driven wheel is connected to the first component and / or the second component via a bearing.

[0032] In most embodiments, the heating source heats the first component and / or the second component, thereby indirectly heating the multi-layer bonded product. In the present invention, the heating source heats the first component or the second component, thereby indirectly heating the multi-layer bonded product. This design cleverly utilizes the clamping component as a heat conduction medium, which not only improves the utilization efficiency of thermal energy, but also achieves uniform heating of the product. The heating process can be precisely controlled as needed, providing favorable conditions for subsequent separation and recycling work. In addition, the introduction of the heating source also helps to improve the flexibility of the material, reduce the difficulty of crushing, and further improve the separation efficiency.

[0033] As a feasible heating method, a cavity is present inside the first component and / or the second component, a hot fluid and / or hot gas is present in the cavity, and the hot fluid and / or hot gas comes from the heating source; and

[0034] All or part of the cavities inside the first component and / or the second component are connected, and the hot fluid and / or hot gas flows in the cavities and conducts heat to the first component and / or the second component.

[0035] By designing cavities inside the first and second components and introducing hot fluids and / or hot gases into the cavities, efficient heating of the clamping components is achieved. This design not only improves the heating efficiency, but also enables the flow of hot fluids and hot gases inside the clamping components through the connectivity of the cavities, ensuring the uniformity of the heating process. In addition, the flow of hot fluids and hot gases also helps to quickly transfer heat, shorten the heating time, and improve the efficiency of the entire separation and recovery process.

[0036] As another feasible heating method, the heating of the first component and / or the second component by the heating source includes electric heating; and

[0037] The electric heating is achieved by connecting a heating wire to one side or both sides of the first component and / or the second component, and the first component and / or the second component connected with the heating wire are made of a heat-conducting material.

[0038] The introduction of electric heating wires, directly connected to one or both sides of the clamping parts, provides a simple, efficient and easy-to-control heating method. The clamping parts are made of heat-conducting materials, which further improves the efficiency of heat transfer and ensures a fast and uniform heating process. This electric heating method is not only easy to operate, but also can be precisely controlled according to actual needs, providing strong thermal support for the separation and recovery of multi-layer bonded products.

[0039] The linear speeds of the first components and / or the second components in press contact with the multi-layer bonded product are the same at the locations where they contact the multi-layer bonded product;

[0040] Preferably, the height of the clamping space formed by the first component and the second component is adjustable.

[0041] Preferably, a pressure sensing mechanism is provided on the first component and / or the second component for adjusting the clamping force of the first component and / or the second component on the multi-layer adhesive product according to the pressure value.

[0042] The above scheme realizes uniform clamping and conveying of the product by ensuring that the linear speeds of the first and second components in contact with the multi-layer bonded product are the same. This design avoids the problem of material damage or incomplete separation caused by inconsistent speeds, and improves the quality and efficiency of separation.

[0043] At the same time, the adjustable clamping space height and the setting of the pressure sensing mechanism enable the equipment to be adaptively adjusted according to different types of multi-layer bonding products, further optimizing the control of the clamping force and ensuring the stability and reliability of the processing process. The comprehensive application of these designs significantly improves the functionality and operational flexibility of the equipment.

[0044] In most embodiments, the apparatus further comprises a bending assembly for bending and separating the extrudable crushable objects and / or polymer materials in the multi-layer bonded product;

[0045] Preferably, the bending assembly comprises at least one gear shifting tube, the gear shifting tube is provided with at least one shifting tooth, and at least one angle pressure plate is provided below the gear shifting tube;

[0046] Alternatively, the bending component is a transverse groove structure;

[0047] Alternatively, the bending component is a clamping device for an elastic hose and a metal pipe.

[0048] The introduction of the bending component significantly enhances the separation efficiency of the extrudable crushed material and the polymer material in the multi-layer bonded product. The design of the bending component allows for further mechanical manipulation of the product after preliminary crushing and heating, and achieves effective separation between the materials through physical bending. This separation method not only avoids the environmental risks that may be caused by the use of chemical solvents, but also is faster and more efficient than traditional methods, which helps to increase the processing speed of the entire recycling process.

[0049] Preferably, the device also includes a back panel removal assembly, which includes a gap for embedding the multi-layer adhesive product therein, and the height of the gap can be adjusted; preferably, the back panel removal assembly includes at least one roller and a baffle; the baffle is arranged above the roller, and the baffle includes a structure welded or threaded by angle steel.

[0050] The addition of the backplane scraper further expands the functionality of the device, enabling it to not only separate glass and polymer materials, but also remove other unwanted materials such as the backplane, making subsequent recycling and reuse processes more convenient.

[0051] In most embodiments, the polymer material includes but is not limited to one or a combination of two or more of PVB film, EVA film, TPE film, POE film, and ETFE film, and the object that can be crushed by being squeezed or hit includes but is not limited to glass and brittle hard transparent plastic;

[0052] Preferably, the multi-layer bonding product is a solar cell panel when a glass panel is bonded on one side;

[0053] Alternatively, the multi-layer bonded product is a photovoltaic panel;

[0054] Alternatively, the multi-layer bonded product is a double-wave board.

[0055] By selecting a variety of polymer materials such as PVB film, EVA film, TPE film, POE film, ETFE film, etc., the applicability of the equipment has been significantly expanded, and it can handle different types of multi-layer bonded products. At the same time, by incorporating glass, brittle hard transparent plastics and other crushable or impactable materials into the processing range, the adaptability of the equipment to various materials has been enhanced. In particular, for products such as solar panels, photovoltaic panels and double-wave panels with single-sided bonded glass panels, the equipment has demonstrated excellent separation efficiency and can achieve efficient and environmentally friendly material separation and recycling.

[0056] In one embodiment, as a further preferred solution, the device further includes:

[0057] A pre-crushing component is arranged at the front end of the clamping and conveying component or in the middle of the clamping and conveying component, and the pre-crushing component is provided with an extrusion component, including but not limited to a tube groove extrusion component, a concave-convex groove extrusion component, a rolling component or a combination thereof;

[0058] The kneading and vibrating assembly is arranged in the middle of the clamping and conveying assembly or behind the clamping and conveying assembly. The kneading and vibrating assembly separates at least one adhesive on the multi-layer adhesive product by rubbing between planes with protrusions.

[0059] By setting a pre-crushing component at the front end or in the middle of the clamping and conveying component, the technical solution realizes the pre-treatment of multi-layer bonded products, wherein the application of extrusion components such as tube groove extrusion components, concave-convex groove extrusion components, and rolling components can effectively perform preliminary crushing of the product, laying a good foundation for the subsequent separation process. In addition, the setting of the kneading and vibration component further promotes the separation of the bonded products through the kneading action between the planes of the protrusions, and improves the fineness and thoroughness of the separation.

[0060] In one embodiment, as a further preferred embodiment, the device also includes at least one click-beating component, which emits point-shaped particles to the surface of the multi-layer bonded product to cause any broken or unbroken extrudable or strikeable object bonded thereto to fall off.

[0061] Preferably, the device includes any kind of magnetic separation component.

[0062] The addition of the point-beating component further enhances the separation effect of crushed or uncrushed extrudable or hittable objects by emitting point-shaped particles to the product surface. The application of the magnetic separation component provides an efficient means for subsequent material sorting and recycling, and improves the automation and intelligence level of the entire recycling process.

[0063] In most embodiments, the line speeds of the respective first components and / or second components in press contact with the multi-layer bonded product are the same at the point of contact with the multi-layer bonded product.

[0064] The height of the clamping space formed by the first component and the second component can be adjusted.

[0065] The first component and / or the second component is provided with a pressure sensing mechanism for adjusting the clamping force of the first component and / or the second component on the multi-layer bonding product according to the pressure value.

[0066] The design of the first component and the second component in the technical solution allows the height of the clamping space to be adjusted, and the clamping force can be precisely controlled through a pressure sensing mechanism, which provides customized processing solutions for different types of multi-layer bonding products and ensures the stability and safety of the clamping and separation processes.

[0067] Advantages and beneficial effects of the present invention:

[0068] First, the technical solution of the present invention has the ability to flatten multi-layer adhesive products such as solar panels, which is crucial for the recycling of multi-layer adhesive products. Traditional processing methods often cannot effectively restore the flatness of multi-layer adhesive products such as solar panels. However, the technical solution can flatten the solar panels during the heating process through a specific mechanical structure design, thereby avoiding deformation and damage of the materials and improving the quality and reuse value of the recycled materials.

[0069] Secondly, the uniformity and controllability of the heating process is another significant feature of the technical solution of the present invention. Through a precise temperature control system, the device can evenly heat the multi-layer bonded product, avoiding the problem of local overheating or insufficient heating. This uniform heating not only helps the effective separation of materials, but also prevents changes in material properties caused by improper temperature control, ensuring the quality and consistency of the recycled materials.

[0070] Third, the heating and flattening process of the technical solution of the present invention is carried out synchronously with the forward transmission, and this design significantly improves the efficiency of the assembly line operation. In the traditional processing flow, the material needs to go through multiple independent processes to complete the heating and flattening, while the technical solution realizes the completion of these processes in a single device through an integrated design, reducing the material handling and processing time, and improving the automation and operation efficiency of the entire production line.

[0071] Fourth, the present invention also provides a speed adjustment function, so that the operator can flexibly adjust the processing speed according to actual needs to adapt to multi-layer adhesive products of different types and states. In addition, the device is specially designed to heat flexible materials, which expands the processing range of the device. The staggered design of the transmission system effectively prevents the material from falling during the processing process, ensures the continuity and stability of the processing process, and further improves the production efficiency and material recovery rate.

[0072] On the other hand, the multi-layer bonded products in the clamping and conveying are heated by a heating source, and the principle of thermal expansion is used to further promote the separation between the materials. This step not only improves the separation efficiency, but also helps to maintain the integrity and purity of the materials.

[0073] In terms of energy consumption, the present invention heats the clamping and conveying assembly by electric heating, wherein the electric heating wire is directly connected to one or both sides of the clamping component, thereby ensuring efficient transfer and utilization of heat energy. At the same time, the cavity design inside the clamping and conveying assembly allows hot fluid and / or hot gas to flow therein, thereby achieving uniform heating of the clamping component and reducing energy waste.

[0074] In terms of operational convenience, the equipment is designed with an adjustable clamping space height and pressure sensing mechanism, so that the equipment can be adaptively adjusted according to different types of multi-layer bonding products, simplifying the operating process and improving the versatility and flexibility of the equipment.

[0075] In general, the device of the present invention not only achieves efficient separation and environmentally friendly treatment at the technical level, but also enhances the adaptability and application range of the device through a series of functional components. For example, it includes a pre-crushing component, a kneading and vibration component, and a back plate scraping component, etc. These components can be selectively used according to different processing requirements, so that the device can handle more types of multi-layer bonded products.

[0076] In addition, the design of certain components of the equipment, such as the bending component and the backsheet removal component, is optimized specifically for specific products such as solar panels, further improving the targetedness and effectiveness of the separation process.

[0077] The equipment of the present invention meets the diversified needs of the modern recycling industry for separation and recycling of multi-layered bonded products by its high efficiency, energy saving and flexible operation characteristics. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0091] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0092] In the following description, certain specific details are set forth for the purpose of illustrating the various disclosed embodiments to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with the present application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0093] References throughout the specification to "one embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0094] Embodiment 1:

[0095] The following takes the disassembly, separation and recycling of solar panels as an example to explain the specific implementation process of the present invention in detail. The implementation methods of other similar multi-layer adhesive products such as laminated glass are basically the same as the disassembly, separation and recycling of solar panels.

[0096] Single-sided glass photovoltaic panels are a common type of solar panels. There are currently two existing treatment technologies for single-sided glass photovoltaic panels. One is direct incineration, which causes serious environmental pollution and has a low utilization rate.

[0097] The second method is to use a tool or a grinding head to grind the glass so that it falls off. The main disadvantages of this method are that first, grinding will cause metal powder to mix into the glass, affecting the usability of the glass. Since the glass itself is very hard and wear-resistant, this will cause a large loss of the grinding head, which is not cost-effective. Since glass is a brittle material, this will cause the glass to be ground into powder, which will result in a low utilization value of the glass. In addition, there will be a lot of glass particles left on the bottom plate, which makes it difficult to recycle and reuse the bottom plate in the future.

[0098] like Figure 1 As shown, the clamping and heating functional device using the multi-layer bonding product of the present invention comprises at least one of the following components or a combination thereof as a whole:

[0099] A clamping and conveying assembly, used to clamp the photovoltaic panel 9 and convey it in a predetermined direction;

[0100] A heating source, used to heat the photovoltaic panel 9 during clamping and conveying;

[0101] A power source is used to drive the clamping and conveying component.

[0102] in, Figure 1 A structure shown in the figure, in which the clamping and conveying assembly comprises at least a plurality of first components 1 whose main parts are cylindrical and are arranged in rows and continuously, and a plurality of second components 2 whose main parts are cylindrical and are also arranged in rows and continuously thereunder.

[0103] The first component 1 and the second component 2 clamp the photovoltaic panel 9, and the first component 1 and the second component 2 clamp and transport the photovoltaic panel 9 in contact with them in a predetermined direction by rotating their cylindrical structures. To this end, the clamping space between the first component 1 and the second component 2 should match the thickness of the photovoltaic panel 9.

[0104] exist Figure 1 In the figure, the second component 2 of the lower layer is used as a heating tube. The tube is heated by the electric heating wire 7. The first component 1 of the upper layer rotates in the opposite direction to the second component 2 of the lower layer (only the upper layer may have a power source). The photovoltaic panel 9 is placed in it and will be clamped and moved forward, and the lower layer heating tube will also rotate with it. Adjacent heating tubes of one layer are connected by gears.

[0105] Of course, in this embodiment, Figure 1 What is shown is mainly the gripping and conveying components, while components such as heating sources can be integrated into one device or exist independently.

[0106] exist Figure 2 In the figure, it can be seen that the whole device is supported by a frame 5, a part of which is used to install a motor 4 as a power source.

[0107] exist Figure 2 In the figure, the clamping and conveying assembly includes a concave-convex structure 3 of the cylindrical part of the first component 1 or the second component 2; during the conveying process of the photovoltaic panel 9, the adjacent first components 1 or second components 2 in the same row are engaged with the concave-convex structure 3 to prevent the photovoltaic panel 9 from curling upward or downward during the conveying process and being squeezed out from the gap between the adjacent first components 1 or the second components 2.

[0108] exist Figure 2 In the embodiment, the cylindrical surfaces of part or all of the first component 1 and / or the second component 2 have concavo-convex structures 3, and the adjacent cylindrical surfaces having concavo-convex structures 3 have concavo-convex correspondingly;

[0109] The specific structure is: the pattern of the concavoconvex is a uniform annular protrusion, and the corresponding pattern of the concavoconvex on the adjacent cylindrical surface with concavoconvex is that the width and depth of the concavoconvex are the same, and the concavoconvex is closely combined. Figure 3 shown.

[0110] Of course, the concave-convex structure 3 can also be adopted as Figure 5 The surface shown is provided with a plurality of densely distributed ridges. The concave-convex structure 3 is arranged on the rotating shaft 102 of the first component 1 and is connected to other components by a bearing 101.

[0111] like Figure 4 As shown, in this embodiment, the clamping and conveying assembly further includes a chain transmission mechanism 6 arranged at one end of the first component 1 and the second component; the power source includes a motor 4 for driving the chain transmission mechanism 6.

[0112] In the clamping and conveying assembly of the present invention, the chain transmission mechanism 6 is a key part for realizing the rotation of the first component 1 and the second component 2. In this embodiment, the chain transmission mechanism 6 is based on a gear transmission structure.

[0113] Combination Figure 4 and Figure 6 As shown, the chain transmission mechanism 6 is composed of a series of driving wheels 601 and driven wheels 602, which are designed based on a gear transmission structure. The driving wheel 601 is directly connected to the motor 4, and is powered by the motor 4 to drive the first component 1 or the second component 2 to rotate. This design allows the first component 1 and the second component 2 to achieve synchronous or relative movement during the conveying process to meet different conveying requirements.

[0114] The driven wheels 602 of the chain transmission mechanism 6 are designed with special functions. They cannot directly drive the first component 1 or the second component 2, but can drive the next adjacent driving wheel 601 to rotate. This design ensures the continuity and stability of the transmission chain and improves the transmission efficiency of the entire conveying assembly. The driven wheel 602 is connected to the first component 1 and the second component 2 through the bearing 101. This bearing connection method can reduce friction and extend the service life of the transmission mechanism.

[0115] In the specific implementation, the driving wheel 601 is connected to the first component 1 and the second component 2 in a non-differential concentric manner, which ensures the accuracy and reliability of the transmission. At the same time, the driving wheel 601 and the driven wheel 602 are staggered on one side or both sides of the adjacent first component 1 and the second component 2. This staggered layout not only increases the stability of the transmission, but also helps to reduce space occupation, making the entire conveying assembly more compact. Through this design, the clamping conveying assembly can adapt to various complex conveying environments and meet diverse industrial production needs.

[0116] at the same time, Figure 6 A setting method of the heating source is also shown. In the clamping heating function device for multi-layer bonded products, the setting of the heating source is crucial. It heats the multi-layer bonded product indirectly by heating the first component 1 or the second component 2. This design allows the heating process to be more uniform and controllable, thereby improving the quality of the bonded product.

[0117] In some embodiments, cavities are designed inside the first component 1 and / or the second component 2, and these cavities can be filled with hot fluids and / or hot gases. These thermal media come from the heating source, and they flow in the cavities and conduct heat to the components to achieve heating. The design of the cavity allows the hot fluid and / or hot gas to flow inside the components, thereby improving the heating efficiency and uniformity.

[0118] Furthermore, the cavities of the first component 1 and / or the second component 2 may be fully or partially connected to form a flow path for the hot fluid and / or hot gas. This connection design helps to achieve more efficient heat transfer, ensure that the multi-layer bonded product is heated evenly during the heating process, and avoid local overheating or insufficient heating.

[0119] In this embodiment, electric heating is adopted. In the electric heating implementation, the electric heating wire 7 is connected to one side or both sides of the first component 1 or the second component 2. Figure 6 The middle heating wire 7 is arranged at the end of the second component 2 where no gear is arranged, and is combined with Figure 7 It can be seen that the heating wire 7 is sequentially connected to the end of the second component 2 in series. At this time, the second component 2 is heated by the heating wire 7, and then the photovoltaic panel 9 clamped by the second component 2 is heated.

[0120] Of course, the arrangement of the heating wire 7 can be adjusted according to actual needs to adapt to different heating requirements. In order to improve the heating efficiency of the heating wire 7, the first component 1 and / or the second component 2 should be made of heat-conducting materials, such as metals, which have excellent heat-conducting properties.

[0121] Finally, in order to ensure the safety and reliability of the heating process, the connection and control of the heating wire 7 need to be precisely designed. The working state of the heating wire 7, for example, can be monitored and adjusted by an electronic control system to achieve precise control of the heating process. In addition, the heat dissipation and protection measures of the heating wire 7 need to be considered to prevent overheating and damage.

[0122] Embodiment 2:

[0123] Based on Example 1, as a further preferred embodiment, the device further comprises a bending component for bending and separating the extrudable crushable objects and / or polymer materials in the multi-layer bonded product.

[0124] like Figure 8 As shown, in this embodiment, the bending assembly includes a gear puller tube 8, on which a plurality of puller teeth 801 are provided; the gear puller tube 8 is arranged behind the clamping and conveying assembly. The first component 1 ensures that the photovoltaic panel 9 is clamped between the first component 1 and the second component 2 through the concave-convex structure 3 thereon, so as to prevent the photovoltaic panel 9 from being squeezed upward from the gap of the adjacent first component 1 after curling.

[0125] At the same time, the photovoltaic panel 9 adopts a single-sided glass structure. Figure 8 In the figure, the upper layer of the photovoltaic panel 9 is a back plate 902, which is generally an EVA film with certain flexibility, and the lower layer is glass 901, which adheres to the back plate 902 and has been broken to a certain extent.

[0126] During the transmission process between the first component 1 and the second component 2, the photovoltaic panel 9 is heated by connecting the electric heating wire 7 to the shaft end of the second component 2, and the adhesion between the glass 901 and the back plate 902 is greatly reduced. The photovoltaic panel 9 is clamped, heated and transported to the bottom of the gear puller 8. The gear puller 8 rotates clockwise, and the puller 801 presses the photovoltaic panel 9 downward, and the bottom of the photovoltaic panel 9 is supported on the angle pressure plate 802 to bend, and the rigid glass 901 breaks, squeezes each other and falls off, and separates from the flexible back plate 902.

[0127] The gear puller tube 8 can be designed to be adjustable, for example, it can be moved forward or backward, or the angle between the puller tooth 801 and the angle pressure plate 802 can be adjusted, and the bending angle of the photovoltaic panel 9 can be changed by changing the angle.

[0128] Since the glass 901 is folded in half by using a bending roller to bend the glass surface, the broken glass particles are squeezed and compressed by adjacent glass particles under the pressure of the forced bending of the bending roller, generating a repulsive force between each other, causing the glass 901 to fall off completely. In this way, there is no need for any consumables such as grinding heads, and since the same materials are squeezed against each other and there is no high-intensity friction and impact like between grinding heads, the glass powder rate is also very low.

[0129] Of course, the above solution is suitable for processing single-sided boards.

[0130] As an alternative, the bending assembly can also adopt a transverse groove structure, for example, a transverse groove is placed horizontally behind the heating device to fold the photovoltaic panel 9 in the opposite direction so that the glass falls off. Of course, it is only suitable for processing single-sided panels.

[0131] As an alternative, the bending assembly can also use a clamping device of an elastic hose and a metal pipe; for example, the gear shifting tube 8 is replaced with a clamping device of an elastic hose and a metal pipe, and the double-sided glass plate can be separated. The upper metal and rubber tube are squeezed together, the film is bent along with the metal tube, and the surface glass 901 will be broken.

[0132] This method of bending the component to separate from the surface glass plate is not suitable for all multi-layer adhesive products. If the polymer material inside has poor flexibility and breaks when bent, the method of the present invention is not applicable.

[0133] Embodiment 3:

[0134] Based on Example 1, as a further preferred solution, the device also includes a backboard scraping component 13.

[0135] like Fig.11As shown, the back plate scraping assembly 13 includes a roller 1302 and a baffle 1303; the baffle 1303 is arranged above the roller 1302, and the baffle 1303 includes a structure welded or threaded by angle steel.

[0136] In order to ensure that the photovoltaic panel 9 in transmission can be smoothly inserted into the gap between the roller 1302 and the baffle 1303, a limiting groove 1301 is set at the discharge position of the clamping and conveying assembly. After the photovoltaic panel 9 conveyed by the clamping and conveying assembly enters the limiting groove 1301, it is smoothly inserted into the gap between the roller 1302 and the baffle 1303, thereby achieving scraping of the back panel through the baffle 1303.

[0137] The roller 1302 is also provided with a hydraulic cylinder for adjusting the height.

[0138] The reason for scraping off the back sheet is that if the back sheet is not scraped off, a large amount of toxic gas will be generated from the back sheet when the photovoltaic panel 9 is placed in the furnace for high-temperature melting.

[0139] Embodiment 4:

[0140] Based on Example 1, as a further preferred solution, the device also includes a pre-crushing component, which is arranged at the front end of the clamping and conveying component, or is independently arranged.

[0141] like Fig.10 As shown, in this embodiment, the pre-crushing assembly includes two extrusion plates 11 that clamp the photovoltaic panel 9, and the two extrusion plates 11 are provided with relative extrusion teeth 12, and the glass 901 on the photovoltaic panel 9 is pre-crushed by the extrusion force. The pre-crushed photovoltaic panel 9 is then heated, crushed, tapped, scraped off the back plate, and magnetically separated, and finally the material is recycled.

[0142] Embodiment 5:

[0143] Based on Example 1, as a further preferred embodiment, the device also includes a crushing component, and the crushing component includes one or more striking parts; the striking parts include but are not limited to hammer parts, cutting parts, friction parts or stirring parts.

[0144] The difference between the pre-crushing assembly and the crushing assembly is that the pre-crushing assembly crushes the photovoltaic panel 9 before it enters the clamping and conveying assembly, while the crushing assembly crushes the photovoltaic panel 9 after it enters the clamping and conveying assembly to promote the falling of the glass 901. It can be arranged behind the clamping and conveying assembly.

[0145] Embodiment 6:

[0146] Based on Example 1, as a further preferred solution, the device further includes a kneading and vibrating assembly, which is arranged in the middle of the clamping and conveying assembly or behind the clamping and conveying assembly. The kneading and vibrating assembly utilizes a flat plate 10 (or a tube) with a protrusion 1001, and the flat plate 10 vibrates, generating a displacement difference between the upper and lower layers in the left and right directions, and the process is repeated to crush the glass 901, causing the glass 901 to fall off (or fall off more easily and be further separated).

[0147] like Fig. 9 As shown, the rubbing and vibration assembly separates the glass 901 on the photovoltaic panel 9 by rubbing between the flat panels 10 provided with protrusions 1001 .

[0148] Embodiment 7:

[0149] Based on Example 1, as a further preferred embodiment, the device also includes at least one click-beating component, which emits point-shaped particles to the surface of the multi-layer bonded product to cause any broken or unbroken extrudable or strikeable object bonded thereto to fall off.

[0150] The click punching components can be completed by sandblasting or shot blasting. The click punching components can be integrated with other components in a set of equipment or exist independently.

[0151] Embodiment 8:

[0152] Based on Example 1, as a further preferred embodiment, the device also includes at least one magnetic separation component.

[0153] The introduction of magnetic separation components is to achieve effective separation of different materials in the separation and recycling process of multi-layer bonded products. The component uses the magnetic difference of each component in the material to attract magnetic particles by generating a magnetic field, while non-magnetic or weakly magnetic materials are not affected.

[0154] In specific implementation, the magnetic separation component can be designed as one or more electromagnetic rollers or drums with magnetic materials wrapped on the surface. When the processed material passes through these electromagnetic rollers or drums, the magnetic particles are adsorbed, while the non-magnetic particles continue to move along the original path, thereby achieving separation of the two materials.

[0155] In the operation process, the magnetic separation component is usually set after the clamping and heating function equipment as the last step of the entire separation and recovery process.

[0156] After heating and flattening, the multi-layer bonded product, in which the magnetic material is effectively separated when passing through the magnetic separation component. The operator can adjust the strength of the magnetic field and the separation speed to meet the separation needs of different materials.

[0157] In addition, the design of the magnetic sorting components allows for quick cleaning and replacement of magnetic materials to accommodate the sorting of different batches or different types of materials, ensuring sorting efficiency and accuracy.

[0158] This magnetic separation method not only improves the separation efficiency of materials, but also ensures the purity of recycled materials, laying a good foundation for subsequent recycling.
