Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of photovoltaic technology, and particularly relates to a double-glass module adhesive film removing device and a double-glass module adhesive film removing process. BACKGROUND
[0002] The double-glass module mainly comprises a front glass layer, an upper encapsulating adhesive film layer, a cell piece layer, a lower encapsulating adhesive film layer and a back glass layer which are sequentially stacked, and the recycling of the photovoltaic module mainly obtains the cell piece layer which is the most valuable, so in the disassembling process, the front glass layer and the upper encapsulating adhesive film layer are generally removed first, and then the back glass layer and the lower encapsulating adhesive film layer are removed (of course, the order of disassembling can be reversed).
[0003] However, in the disassembling and recycling process, after the glass layer is removed, the next process of removing the adhesive film layer is directly entered, the means for removing the adhesive film layer mainly includes grinding or hob cutting, and feeding roller groups and receiving roller groups are arranged at both ends of the cutting area to assist the cutting, that is, the adhesive film layer is removed by cutting during the movement of the module, but in actual operation, the following technical defects exist:
[0004] 1) When the end of the module is separated from the restriction of the feeding roller group, the section of the module is a free section, if the rolling cutting is adopted, the free section will be deformed with the hob cutting, not only the cutting safety hazard exists, but also the cell piece layer and the back glass layer are passively damaged;
[0005] 2) When the glass is removed, a small amount of glass residue is inevitably formed on the surface layer, and the restriction force provided by the feeding roller group used in the process of feeding the module is not adaptively adjusted according to the convex-concave change of the surface layer, so that the module will be pulled in the movement direction due to the different restriction forces, and then the cutting quality is difficult to meet the expectation in the pulling environment, that is, the transition cutting causes the damage of the cell piece, or the cutting is insufficient to cause the residue of the adhesive film layer; in addition, due to the glass residue, the cutting force is uneven, the module deviation probability is increased, and the cutting quality is also affected. SUMMARY
[0006] The technical problem to be solved by the application is to overcome the deficiencies of the prior art, and to provide an improved double-glass module adhesive film removing device.
[0007] The application also relates to a double-glass module adhesive film removing process.
[0008] To solve the above technical problems, the technical scheme adopted by the application is as follows:
[0009] A film removal device for double-glass modules includes a conveyor roller assembly and a cutting module. The conveyor roller assembly includes multiple conveyor rollers arranged side-by-side at intervals at the bottom, and feed rollers and discharge rollers located at the inlet and outlet ends of the cutting module and respectively matched with the lower conveyor rollers. The film removal device also includes a pressing module disposed between the feed rollers and the cutting module. The pressing module includes a bottom mold located between two adjacent conveyor rollers and forming a bottom support, and a pressing mold located above the bottom mold and maintaining a downward elastic movement tendency. The pressing mold includes components installed side-by-side on the same... Multiple pressers on the shaft seat and respectively rotate and press against the bottom mold. The contact surface formed by each presser foot is inclined downward from the tip and presses down, with the tip close to the cutting module. The component is fed into the space between the presser foot and the bottom mold by the feed roller. Each presser foot rotates around the connection of the shaft seat to change the inclination angle of the presser foot surface. Each presser foot adapts to the concave and convex changes of the component surface and adjusts the pressing angle accordingly. At the same time, each presser foot squeezes and removes the residual glass on the surface of the component as the component moves. The restraining force formed by the tip of the foot close to the cutting module is used to counteract the stress caused by the cutting module to deform or shift the component.
[0010] Preferably, the bottom die extends along the length of the transfer roller, and the top surface of the bottom die is flush with the top surface of the transfer roller. The comprehensive support of the bottom die further enhances the clamping force, providing optimal conditions for auxiliary cutting.
[0011] Preferably, the top surface of the bottom mold includes a gradually sloping guide slope from bottom to top and a top support surface extending horizontally from the guide slope, wherein the top support surface is flush with the top surface of the transfer roller. A guide is formed based on the guide slope, thereby more accurately delivering the component between the top support surface and the toe.
[0012] According to a specific embodiment and preferred aspect of the present invention, the bearing seat includes a fixed frame, a pivot mounted on the fixed frame and arranged parallel to the transfer roller, and each pressure foot includes a pressure foot body rotatably mounted on the pivot and an elastic member elastically disposed between the pressure foot body and the fixed frame and holding the tip of the pressure foot body downward. Each pressure foot corresponds to one elastic member, that is, the movement of each pressure foot is relatively independent. Therefore, it satisfies the requirement for adjusting the downward pressure under different thicknesses, so as to avoid uneven downward pressure causing movement and pulling.
[0013] Preferably, each pressure plate body rotates on a pivot based on a bearing.
[0014] Furthermore, multiple pressure feet are fitted together to form a pressure foot surface that covers the entire width of the module. This is because the pressure feet not only provide downward pressure but also remove the glass from the module surface.
[0015] In some specific embodiments, the presser foot body includes a presser foot module forming a toe and a docking module extending upward from the rear end of the presser foot, wherein an elastic component is installed between the docking module and the fixing frame.
[0016] Preferably, a movable groove is provided at the upper end of the docking module, and the elastic component includes a connecting bolt that passes through the movable groove and is connected to the fixed frame, and a spring that is sleeved on the outer periphery of the connecting bolt and elastically abuts against the docking module and the fixed frame, wherein the docking module rotates relative to the connecting bolt based on the movable groove to adaptively change the pressing angle.
[0017] According to a specific embodiment and preferred aspect of the invention, the cutting module includes a roller cutter, wherein the centerline of the roller cutter is vertically aligned with the centerline of the conveyor roller directly below it. This ensures relatively stable cutting quality during cutting in the bottom support mode.
[0018] Preferably, the roller cutter rotates in opposite directions to the corresponding conveyor roller below, causing the roller cutting and pushing assembly to move forward. In other words, the roller cutting direction and the moving direction are the same, which is more conducive to efficient cutting.
[0019] According to a specific embodiment and preferred aspect of the invention, the discharge roller is aligned with the transfer roller directly below it and is an elastically floating roller based on changes in component thickness. This allows for adaptive adjustment as the component thickness changes, enhancing practicality.
[0020] Preferably, there are multiple discharge rollers, and a brush roller group is provided between two adjacent discharge rollers, wherein the brushing is used to remove debris from the surface of the cut battery cells.
[0021] Furthermore, the brush assembly consists of at least two brushes, with adjacent brushes rotating in opposite directions. By brushing in different directions, residues formed on the battery surface after cutting are avoided, thereby improving the quality of adhesive film removal.
[0022] In some implementations, there are two roller brushes, each aligned with the transfer roller directly below. This ensures that brushing does not interfere with the normal transport of the components and maintains alignment with the base for auxiliary transport.
[0023] Another technical solution of the present invention is: a process for removing the encapsulant film from a double-glass module, which uses the above-mentioned encapsulant film removal equipment for double-glass modules and includes the following steps:
[0024] S1, Cutting Adjustment
[0025] Based on the thickness of the components, adjust the distance between the feed roller, the cutting component, the discharge roller and the transfer roller, while multiple press feet are aligned and pressed down on the bottom mold, with the tips of the press feet extending into the lower side of the cutting component;
[0026] S2, Cutting off the adhesive film
[0027] First, the component enters the feeding channel formed by the feed roller and the transfer roller with the adhesive film layer facing upwards, and continues to move forward. The bottom of the component is slidably supported on the bottom mold, and the top is relatively lifted up by the foot tips. At this time, the foot tips rotate around the center of rotation and insert forward relative to the component to cut it. At the same time, the foot tips adjust the tilt angle of the pressure foot surface based on the surface of the component, and each pressure foot squeezes and removes the residual glass on the surface of the component as the component moves. Second, the component enters the cutting area formed by the cutting module to cut the surface adhesive film layer. At the same time, the restraining force formed by each foot tip counteracts the stress caused by the cutting module to deform or shift the component. Finally, the component with the adhesive film layer removed enters the discharge channel formed by the discharge roller.
[0028] Preferably, in step S2, after the component enters the discharge channel, it needs to be brushed in both forward and reverse directions to remove adhesive film debris adhering to the surface. This multi-directional brushing reduces the residual adhesive film layer on the cell surface.
[0029] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:
[0030] In existing double-glass modules, during the removal of the encapsulant layer, once the module end is freed from the restraint of the feed roller assembly, this free section deforms as the roller cutter cuts, posing not only a cutting safety hazard but also causing passive damage to the solar cell layer and the back glass layer. Simultaneously, a small amount of glass residue inevitably forms on the surface during glass removal. Since the restraining force provided by the feed roller assembly during module feeding does not adaptively adjust to changes in surface unevenness, the module will experience pulling motion in the direction of movement due to variations in the restraining force. Therefore, cutting in this tensile environment presents a challenge. The cutting quality of existing double-glass modules is often unsatisfactory, either due to over-cutting which damages the cells or under-cutting which leaves encapsulant residue. Furthermore, glass residue causes uneven cutting force, increasing the probability of module misalignment and affecting cutting quality. This invention, however, cleverly addresses these shortcomings by comprehensively designing the structure of the encapsulant removal equipment for double-glass modules. The equipment first adjusts the distances between the feed roller, cutting component, and discharge roller relative to the transfer roller based on the module thickness. Simultaneously, multiple pressure feet align and press down on the bottom mold, with the toes extending outwards. The component enters the cutting assembly from the lower side; secondly, the component enters the feeding channel formed by the feed roller and the transfer roller with the adhesive film layer facing upwards, and continues to move forward. The bottom of the component is slidably supported on the bottom mold, and the top is relatively lifted by the foot tips. At this time, the foot tips rotate around the center of rotation and insert forward relative to the cutting assembly. At the same time, the foot tips adjust the tilt angle of the pressure foot surface based on the surface adaptability of the component, and each pressure foot squeezes and removes the residual glass on the surface of the component as the component moves; then, the component enters the cutting area formed by the cutting module to cut the surface adhesive film layer, and the restraining force formed by each foot tip counteracts the deformation of the component caused by the cutting module. Or the stress of displacement; finally, the component with the removed adhesive film layer enters the discharge channel formed by the discharge roller to complete the process of removing the adhesive film layer from the surface of the component. Therefore, this application, on the one hand, is based on the relative pressing assistance formed by the die and the bottom die, which not only offsets the stress of deformation or displacement caused by the cutting module to the component, but also optimally shortens the length of the free section to eliminate cutting safety hazards and reduce the damage rate caused by the movement of the battery cells; on the other hand, each pressure foot adaptively adjusts the downward pressure based on the unevenness of the component surface, which not only avoids the movement pulling caused by the downward pressure, but also the extrusion formed can remove residual glass, thereby improving the cutting quality.

[0049] like Figures 1 to 6 As shown, the adhesive film removal equipment for double-glass modules involved in this embodiment includes a conveying roller group 1, a cutting module 2, a pressing module 3, a brushing roller group 4, a feeding roller 5, and a discharging roller 6.
[0050] Specifically, the conveyor roller group 1 includes multiple conveyor rollers 10 that are synchronously connected. The multiple conveyor rollers 10 are arranged horizontally and are arranged side by side and spaced apart. That is, the top surface of the multiple conveyor rollers 10 constitutes the conveying surface.
[0051] In some specific embodiments, along the direction of component movement, the feed roller 5, the pressing module 3, the cutting module 2, the discharge roller 6, the brushing roller group 4, and the discharge roller 6 are arranged sequentially above the corresponding transmission roller 10.
[0052] The cutting module 2 includes a roller cutter 20, the centerline of which is vertically aligned with the centerline of the conveyor roller 10 directly below. This ensures relatively stable cutting quality during cutting in the bottom support mode. The roller cutter 20 and the aligned conveyor roller 10 rotate towards each other, causing the roller cutting and pushing components to move forward. In other words, the roller cutting direction and the moving direction are the same, which is more conducive to efficient cutting.
[0053] The pressing module 3 includes a bottom mold 30 located between two adjacent transfer rollers 10 and forming a bottom support, and a pressing mold 31 located above the bottom mold 30 and maintaining a downward elastic movement tendency. The bottom mold 30 extends along the length of the transfer rollers 10, and its top surface m is flush with the top surface of the transfer rollers 10. The full support of the bottom mold further enhances the clamping auxiliary force, providing optimal conditions for auxiliary cutting. The top surface m of the bottom mold 30 includes a gradually sloping guide slope m1 and a horizontally extending top support surface m2 from the guide slope m1, wherein the top support surface m2 is flush with the top surface of the transfer rollers 10. The guide slope forms a guiding guide, thereby more accurately feeding the component between the top support surface and the tip of the pressing mold 31. The pressing mold 31 includes multiple pressing feet 310 mounted side by side on the same bearing S and respectively rotating and pressing against the bottom mold 30. The contact surface formed by each pressing foot 310 is inclined downward from the tip and pressed close to the cutting module 2.
[0054] In some specific embodiments, the bearing S includes a fixed frame s1 and a pivot s2 mounted on the fixed frame s1 and arranged parallel to the transfer roller 10. Each pressure foot 310 includes a pressure foot body a rotatably mounted on the pivot s2 and an elastic component b elastically disposed between the pressure foot body a and the fixed frame s1, maintaining the tip of the pressure foot body a downward pressure. Each pressure foot 310 corresponds to one elastic component b, that is, the movement of each pressure foot is relatively independent, thus satisfying the need for pressure adjustment under different thicknesses to avoid uneven pressure causing movement pulling. In this example, each pressure foot body a rotates on the pivot s2 based on bearings. Multiple pressure foot bodies a are relatively attached and form a pressure foot surface covering the entire width of the assembly. This is because the pressure foot body not only provides downward pressure but also removes glass from the surface of the assembly. The pressure foot body a includes a pressure foot module a1 forming the tip and a docking module a2 extending upward from the rear end of the pressure foot, wherein the elastic component b is installed between the docking module a2 and the fixed frame s1. A movable groove is provided at the upper end of the docking module a2. The elastic component b includes a connecting bolt b1 that passes through the movable groove and is connected to the fixed frame s1, and a spring b2 that is sleeved on the outer periphery of the connecting bolt b1 and elastically abuts against the docking module a2 and the fixed frame s1. The docking module a2 is flipped relative to the connecting bolt b1 based on the movable groove to adaptively change the downward pressure angle.
[0055] The discharge roller 6 is aligned with the transfer roller 10 directly below it and is an elastic floating roller based on changes in component thickness. This allows for adaptive adjustment according to changes in component thickness, enhancing practicality. There are two discharge rollers 6, and a brush roller assembly 4 is provided between adjacent discharge rollers 6, where brushing is used to remove debris from the surface of the cut battery cells. In some embodiments, the brush roller assembly 4 consists of at least two brushes 40, with adjacent brushes 40 rotating in opposite directions. By brushing in different directions, residue formed by the adhesive film layer adhering to the battery surface after cutting is avoided, thereby improving the quality of adhesive film removal. In this example, there are two brushes 40, each brush 40 being aligned with the transfer roller 10 directly below it. This ensures that brushing does not affect the normal transfer of the components and maintains alignment with the base for auxiliary transfer.
[0056] In summary, the encapsulant removal process for the double-glass module in this embodiment uses the aforementioned encapsulant removal equipment for double-glass modules and includes the following steps:
[0057] S1, Cutting Adjustment
[0058] Based on the thickness of the components, adjust the distance between the feed roller, the cutting component, the discharge roller and the transfer roller, while multiple press feet are aligned and pressed down on the bottom mold, with the tips of the press feet extending into the lower side of the cutting component;
[0059] S2, Cutting off the adhesive film
[0060] First, the component enters the feeding channel formed by the feed roller and the transfer roller with the adhesive film layer facing upwards, and continues to move forward. The bottom of the component is slidably supported on the bottom mold, and the top is relatively lifted up by the foot tips. At this time, the foot tips rotate around the center of rotation and insert forward relative to the component to cut it. At the same time, the foot tips adjust the tilt angle of the pressure foot surface based on the surface of the component, and each pressure foot squeezes and removes the residual glass on the surface of the component as the component moves. Second, the component enters the cutting area formed by the cutting module to cut the surface adhesive film layer. At the same time, the restraining force formed by each foot tip counteracts the stress caused by the cutting module to deform or shift the component. Finally, the component with the adhesive film layer removed enters the discharge channel formed by the discharge roller.
[0061] Furthermore, in step S2, after the module enters the discharge channel, it needs to be brushed in both forward and reverse directions to remove adhesive film debris adhering to the surface. This multi-directional brushing reduces the residual adhesive film layer on the cell surface. Simultaneously, the module is fed from the feed roller between the pressure feet and the bottom mold. Each pressure foot rotates around the shaft connection, changing the inclination angle of the pressure foot surface. Furthermore, each pressure foot adaptively adjusts its pressing angle based on the unevenness of the module surface. As the module moves, each pressure foot squeezes away any remaining glass on the module surface. The restraining force formed by the foot tip close to the cutting module counteracts the stress caused by deformation or displacement of the module by the cutting module.
[0062] In summary, after adopting the adhesive film removal equipment for this double-glass module, firstly, based on the module thickness, the distance between the feed roller, cutting component, and discharge roller relative to the transfer roller is adjusted. Simultaneously, multiple pressure feet are aligned and pressed down on the bottom mold, with the tips extending into the lower side of the cutting component. Secondly, the module enters the feeding channel formed by the feed roller and transfer roller from the adhesive film layer upwards, while continuing to move forward. The bottom of the module slides and is supported by the bottom mold, while the top relatively lifts the pressure feet. At this time, the pressure feet rotate around the center of rotation and insert forward relative to the cutting component. Simultaneously, the inclination angle of the pressure foot surface is adjusted based on the module surface adaptability, and each pressure foot, as the module moves, squeezes out the remaining glass from the module surface. The process involves pressing to remove the adhesive film layer. Next, the module enters the cutting area formed by the cutting module for surface adhesive film removal. Simultaneously, the restraining force formed by each foot counteracts the stress caused by deformation or displacement of the module by the cutting module. Finally, the module with the adhesive film layer removed enters the discharge channel formed by the discharge roller, completing the process of removing the adhesive film layer from the module's surface. Therefore, this application, on the one hand, utilizes the relative pressing assistance formed by the pressure mold and the bottom mold to not only counteract the stress caused by deformation or displacement of the module by the cutting module, but also optimally shortens the length of the free section to eliminate cutting safety hazards and reduce the damage rate caused by cell movement. On the other hand, each pressure foot adapts to the unevenness of the module surface. The adjustment of downward pressure not only avoids pulling caused by downward pressure, but also the resulting extrusion can remove residual glass, thereby improving cutting quality. Thirdly, the comprehensive support of the bottom mold further enhances the clamping auxiliary force, providing optimal conditions for auxiliary cutting. Simultaneously, the guide slope forms a guide, thus more accurately delivering the component between the top support surface and the toe. Fourthly, each pressure foot corresponds to an elastic component, meaning the movement of each pressure foot is relatively independent. Therefore, it satisfies the need for downward pressure adjustment under different thicknesses, avoiding pulling caused by uneven downward pressure. Furthermore, each pressure foot body rotates on a pivot based on bearings, and multiple pressure foot bodies are relatively close together to form a shape. The pressure foot covers the entire width of the component because the pressure foot body not only provides downward pressure but also removes the glass from the component surface. In addition, a movable groove is provided at the upper end of the docking module. The elastic components include a connecting bolt that runs through the movable groove and is connected to the fixed frame, and a spring that is sleeved on the outer periphery of the connecting bolt and elastically abuts against the docking module and the fixed frame. The docking module is rotated relative to the connecting bolt based on the movable groove to adaptively change the downward pressure angle. Fifthly, the center line of the roller cutter is aligned vertically with the center line of the transfer roller directly below, ensuring that cutting is performed in the bottom support mode, which has relatively stable cutting quality. At the same time, the roller cutting direction and the moving direction are the same, which is more conducive to efficient cutting.The sixth aspect involves aligning the discharge rollers with the transfer rollers directly below them. These rollers are flexible floating rollers designed to adapt to changes in module thickness, enhancing practicality. Multiple discharge rollers are present, with brush roller assemblies between adjacent rollers. These brushes remove debris from the surface of the cut battery cells. Each brush roller assembly consists of at least two brushes rotating in opposite directions. This directional brushing prevents residue from adhering to the battery surface after cutting, improving the quality of adhesive film removal. The brushes are aligned with the transfer rollers directly below, ensuring that brushing does not interfere with normal module transfer and maintains alignment with the base for auxiliary transfer.
[0063] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.

11. The adhesive film removal device for double-glass modules according to claim 10, characterized in that: The brush assembly consists of at least two brushes, and the rotation directions of two adjacent brushes are opposite.
12. The adhesive film removal device for double-glass modules according to claim 11, characterized in that: There are two roller brushes, each of which is aligned with the conveyor roller directly below it.
13. A process for removing the adhesive film from a double-glass module, characterized in that, It employs the adhesive film removal equipment for the double-glass module as described in any one of claims 1 to 12, and includes the following steps: S1, Cutting Adjustment Based on the thickness of the components, adjust the distance between the feed roller, the cutting component, the discharge roller and the transfer roller, while multiple press feet are aligned and pressed down on the bottom mold, with the tips of the press feet extending into the lower side of the cutting component; S2, Cutting off the adhesive film First, the component enters the feeding channel formed by the feed roller and the transfer roller with the adhesive film layer facing upwards, and continues to move forward. The bottom of the component is slidably supported on the bottom mold, and the top is relatively lifted up by the foot tips. At this time, the foot tips rotate around the center of rotation and insert forward relative to the component to cut it. At the same time, the foot tips adjust the tilt angle of the pressure foot surface based on the surface of the component, and each pressure foot squeezes and removes the residual glass on the surface of the component as the component moves. Second, the component enters the cutting area formed by the cutting module to cut the surface adhesive film layer. At the same time, the restraining force formed by each foot tip counteracts the stress caused by the cutting module to deform or shift the component. Finally, the component with the adhesive film layer removed enters the discharge channel formed by the discharge roller.
14. The encapsulant removal process for a double-glass module according to claim 13, characterized in that, In step S2, after the component enters the discharge channel, it needs to be brushed in both forward and reverse directions to remove the adhesive film debris attached to the surface.
