Abstract
Description
[0001] This application is a divisional application of the application with the application date of December 25, 2024, application number 2024119213450, and title of on-site recycling equipment and process for single-container double-glass. Technical Field
[0002] The invention belongs to the technical field of double-glass module recycling, and specifically relates to an on-site glass removal process for single-container double-glass modules. Background Art
[0003] Double-glass photovoltaic modules (hereinafter referred to as double-glass modules) mainly include solar cells, front glass layer, back glass layer, and junction box. The general on-site recycling process includes a feeding station, a junction box removal station, a front glass layer removal station, a back glass layer removal station, and a discharging station. For framed double-glass photovoltaic modules, a frame removal station is also required. Therefore, whether it is a frameless double-glass photovoltaic module or a framed double-glass photovoltaic module, obviously, they cannot be arranged in the same container (due to the length limitation of the container). However, in actual operation, there are still the following technical defects:
[0004] 1) Due to the length limitation of the container, basically two or more sections need to be assembled. Although it can reduce the cost of on-site recycling, due to the use of multiple sections, there are limitations in both equipment transportation and site restrictions, and it is impossible to achieve the required low-cost, fast, and highly adaptable battery cell recycling and processing.
[0005] 2) Regarding glass removal, some manufacturers remove the glass on the front and back simultaneously, while others remove the glass on the front and back sequentially. For simultaneous milling of the front and back, the milling is greatly affected by the glass thickness and cannot meet the on-site use requirements. Moreover, once the module itself is deformed, it is very difficult to perform equal-thickness milling, resulting in a low glass removal rate and an increased damage rate of the battery cells. When removing the glass sequentially, since the output of the previous peeling cannot be kept flat, and after the previous peeling is completed, the module needs to be flipped, and then the same peeling action is performed to complete the secondary peeling. Such an implementation method not only occupies a large space, but also requires flipping and relative shaping and flattening. Therefore, the finally formed glass removal rate is unstable, and it is also very difficult to achieve the required glass removal quality for deformed modules.
[0006] 3) For double-glass modules, whether they are framed double-glass modules or frameless double-glass modules, the recycling equipment is selected according to the product characteristics. Therefore, the functions of the recycling equipment are relatively single, that is, there is no optional or general-purpose recycling and processing equipment that can also be accommodated in the same container on the market. Summary of the Invention
[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved on-site glass removal process for single-container double-glass modules.
[0008] To solve the above technical problem, the present invention adopts the following technical solutions:
[0009] An on-site glass removal process for single-container double-glass modules, the glass removal device used therein includes a front glass removal unit and a back glass removal unit located in the same container, and it includes the following steps:
[0010] S1. Back glass removal
[0011] The double-glass module enters the leveling channel formed between the annular pressing belt and the leveling module horizontally with the front side facing up and the back side facing down. Under the transmission of the upper annular pressing belt, the back glass sequentially contacts the lower cutting assembly and the secondary roller brush peeling assembly to remove the back glass. The lower cutting assembly includes a plurality of lower cutting tools that form relative intervals in each area and are relatively displaced front and back. Based on the cutting formed by the lower cutting tools and the cooperation of the secondary roller cutting, the forces received by the module cancel each other out in the width direction of the module, so as to horizontally output the module with the back glass removed forward.
[0012] S2. Front glass removal
[0013] The module transmitted from step S1 enters the leveling channel formed between the lower annular pressing belt and the upper leveling module. Under the transmission of the lower annular pressing belt, the front glass is first subjected to roll pressing and crushing and then cut by the upper cutting assembly to remove the front glass. Based on the roll pressing wedging or jamming into the front glass to form a wide-width roll pressing and crushing in the corresponding area, and the forces formed by the crushing in the lateral and forward directions and the forces formed by the upper cutting assembly on the module cancel each other out in the width direction of the module, so as to horizontally output the battery cells forward.
[0014] According to a specific implementation and preferred aspect of the present invention, a preheating treatment unit is also provided in the same container, and the glass removal process further includes: step S0. Preheating treatment, which sends the double-glass module into a pretreatment furnace at a temperature of 80-100°C for heating treatment to soften the adhesive layer of the double-glass module. Based on the softening of the adhesive layer, when cutting in the subsequent process, it is more labor-saving to relatively separate the glass from the battery cells.
[0015] According to another specific implementation and preferred aspect of the present invention, when the back glass is removed, the front end of the component enters the leveling channel of the front glass removal unit, and the rear end of the component is between the secondary roller brush stripping component and the upper annular pressure belt to complete the secondary roller brush stripping during the motion guide. Here, the removal of the two glass layers can be carried out separately or in association. However, considering the length of the container, the association mode is generally adopted, because in this mode, not only can the installation space be reduced, but the guide and the output can also restrain and assist each other, reducing the probability of component deviation caused by the secondary roller brush stripping.
[0016] According to another specific implementation and preferred aspect of the present invention, the roller crushing assembly used for roller crushing in step S2 includes a roller body extending along the width direction of the assembly, and a plurality of roller pins distributed circumferentially around the roller body, wherein the roller pins contact the glass during the self-rotation of the roller body, the glass is crushed and the forces in the lateral and forward directions and the forces formed by the upper cutting assembly on the assembly offset each other in the width direction of the assembly, so that the battery sheet is horizontally output forward under the movement of the lower annular pressing belt. Based on the contact and movement of the roller pins, not only the glass layer is better crushed to reduce the difficulty of sawing, but also lateral slippage is avoided (because the glass surface is very smooth) to assist transmission.
[0017] Preferably, the plurality of roller nails form a plurality of roller nail groups, wherein the plurality of roller nail groups are distributed at intervals along the length direction of the roller body.
[0018] Furthermore, the multiple roller pins of each roller pin group are arranged in a circular array in the circumference of the roller body at the same inclination angle as the roller body. Here, the contact and movement formed by the inclination have the following benefits: 1. The force is decomposed to both sides to avoid the pressure concentration caused by the roller pin contacting the glass, which may cause the component to jam; 2. The stress generated by sawing is effectively coordinated to form a lateral force that offsets each other, so that the surface glass can be removed smoothly.
[0019] According to another specific implementation and preferred aspect of the present invention, the inclination direction of each two adjacent groups of roller spikes is respectively toward the two ends of the roller body, and the two adjacent groups of roller spikes are aligned or staggered in the axial direction of the roller body. Based on the staggered or aligned distribution, inclined forces in different directions are formed, and the crushing area formed is also increased (especially when staggered).
[0020] Preferably, each upper cutting tool is a saw disc that can rotate around the vertical direction for sawing, and the thickness of the saw disc is greater than the thickness of the glass layer, and the upper leveling module is provided with an avoidance notch that matches the saw disc. The glass is cut off by sawing.
[0021] Further, the upper cutting assembly further includes power seats corresponding to each saw blade one by one and capable of moving up and down for adjustment. Each saw blade is matched with a power motor, and the power motor is installed on the power seat. That is, each saw blade corresponds to one motor, and the formed sawing amount can be adjusted.
[0022] According to another specific implementation and preferred aspect of the present invention, the upper cutting assembly further includes dust collection pipes corresponding to each avoidance notch and located above each saw blade, and a negative pressure dust collector connected to the plurality of dust collection pipes. The bottom of the dust collection pipe is open, and the fragments formed by cutting are adsorbed and collected based on negative pressure. Here, the broken glass is collected based on the negative pressure dust collector, and the negative pressure dust collector itself has solid-gas separation.
[0023] Preferably, the plurality of saw blades are at least divided into two rows, and the rotation directions of the saw blades in each row are the same and / or opposite. Based on the layout of the rotation directions, the magnitude of the lateral force is reduced, so as to maintain sawing during forward pushing.
[0024] Further, the adjacent two rows of the saw blades are alternately spaced in the width direction of the assembly. Ensure that the sawing area covers the entire width of the assembly.
[0025] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:
[0026] As for the on-site glass removal of existing double-glass modules, some manufacturers remove the glass on the front and back sides simultaneously, while others remove the glass on the front and back sides in sequence. As for the simultaneous milling of the front and back sides, the milling is greatly affected by the thickness of the glass and cannot meet the needs of on-site use. Moreover, once the module itself is deformed, it is difficult to perform milling of equal thickness. The resulting glass removal rate is low and the damage rate of the battery cells will increase. As for the sequential glass removal, the output cannot be kept flat due to the previous stripping, and the module needs to be flipped after the previous stripping is completed, and the same stripping action is performed to complete the secondary stripping. This implementation method not only The space occupied by the double-glass component is large, and it needs to be turned over and relatively shaped and flattened. Therefore, the final glass removal rate is unstable, and it is difficult to achieve the desired glass removal quality for deformed components, etc. The present invention designs the on-site glass removal process structure of the single-container double-glass component as a whole, and cleverly solves the shortcomings and defects of the prior art. After adopting the on-site glass removal process of the single-container double-glass component, the double-glass component is first kept with the front side facing up and the back side facing down horizontally entering between the annular pressing belt and the leveling module to form a leveling channel, and under the transmission of the upper annular pressing belt, the back glass contacts the lower cutting component and A secondary roller brush stripping assembly is used to remove the back glass, wherein the lower cutting assembly includes a plurality of lower cutting tools that are relatively spaced apart in each area and relatively staggered in the front and back. The cutting and secondary roller cutting formed by the lower cutting tools are coordinated so that the forces acting on the assembly offset each other in the width direction of the assembly, so that the assembly with the back glass removed is output horizontally forward; secondly, the assembly enters the lower annular pressing belt and the upper leveling module to form a leveling channel, and under the transmission of the lower annular pressing belt, the front glass is successively roller crushed and cut by the upper cutting assembly to remove the front glass, wherein the roller crushing forms the lateral and forward directions. The force and the force generated by the upper cutting component on the component offset each other in the width direction of the component to output the battery cell forward horizontally. Therefore, compared with the prior art, the present invention, on the one hand, removes the back and front glass layers in sequence without flipping the component, and shortens the length required for glass removal as much as possible to meet the on-site recycling needs of a single container; on the other hand, the forces acting on the component can be offset in the width direction of the component during the removal of the front and back glass, and can also achieve forward horizontal output guidance, thereby reducing the damage rate of the battery cell and being unaffected by component deformation or damage, and having strong practicality.

[0041] As Figures 1 to 7 shown, the single-container double-glass on-site recycling equipment of this embodiment includes a container 1, a feeding device 2, a junction box removal device 3, a frame removal device 4, and a glass removal device 5 that are sequentially arranged in the same container 1. In short, according to actual needs, after this equipment is used on-site, whether it is a framed double-glass component or a frameless double-glass component, the battery cells can be recycled, increasing the practicality of the equipment.
[0042] Specifically, the structures of the container 1, the feeding device 2, the junction box removing device 3, and the frame removing device 4 are the same as those involved in CN202411572231.X, and will not be elaborated here. At the same time, the adopted glass removing device 5 includes a preheating treatment unit 50, a front glass removing unit 51, and a back glass removing unit 52. Among them, the back glass removing unit 52 is the same as the glass removing mechanism in CN202411572231.X, and will not be elaborated here. That is, compared with CN202411572231.X, the main differences of this application are as follows: 1. The object to be recycled is a double-glass module; 2. The glass is peeled off by adopting a continuous and sequential glass removing method, and the adopted front glass removing unit 51 and back glass removing unit 52 are similar but also different; 3. The specific peeling process formed is different.
[0043] The specific differences are as follows:
[0044] In this application, the front glass removing unit 51 includes a lower annular pressing belt 510 located at the bottom, an upper flat module 511 located above the lower annular pressing belt 510, and an upper cutting module 512. A first leveling channel is formed between the lower annular pressing belt 510 and the upper flat module 511. The upper cutting module 512 includes a roll pressing and crushing assembly G and an upper cutting assembly Q located at the inlet and outlet ends of the first leveling channel. The roll pressing and crushing assembly G can wedge into or engage with the front glass to form a wide-width roll pressing and crushing in the corresponding area. The upper cutting assembly Q includes a plurality of upper cutting tools q1 that are relatively spaced in each area and are relatively displaced front and back. The forces formed by the plurality of upper cutting tools q1 and the roll pressing and crushing assembly G on the module cancel each other out in the wide-width direction of the module, so as to horizontally output the battery cells forward under the movement of the lower annular pressing belt 510.
[0045] Specifically, the roller crushing assembly G includes a roller body g1 extending along the width direction of the assembly, and a plurality of roller pins g2 distributed circumferentially around the roller body g1, wherein the roller pins g2 contact the glass during the self-rotation of the roller body g1, the glass is broken and a force in the lateral and forward directions is formed to assist the assembly in translational cutting. Based on the contact and movement of the roller pins, not only the glass layer is broken better to reduce the difficulty of sawing, but also lateral slippage is avoided (because the glass surface is very smooth) to assist transmission. The plurality of roller pins g2 form a plurality of roller pin groups, wherein the plurality of roller pin groups are distributed at intervals along the length direction of the roller body g1. The plurality of roller pins g2 of each roller pin group maintain a circular array with the same inclination angle as the roller body g1 in the circumferential direction of the roller body. Here, the contact and movement formed based on the inclination have the following benefits: 1. The force is decomposed to both sides to avoid the pressure concentration caused by the roller pin contacting the glass at the moment, which leads to the jamming of the assembly; 2. The stress generated by sawing is effectively coordinated to form a mutually offset lateral force, so that the surface glass can be removed smoothly. Each two adjacent groups of roller nails are tilted towards the two ends of the roller body, and the two adjacent groups of roller nails are aligned (displaced) in the axial direction of the roller body. Based on the dislocation or alignment distribution, the tilting forces in different directions are formed, and the formed broken area is also increased (especially when the dislocation distribution is used). In this example, the wedging or clamping length of the roller nails is less than the thickness of the glass.
[0046] Each upper cutting tool q1 is a saw disc that can rotate and saw in a vertical direction, and the thickness of the saw disc is greater than the thickness of the glass layer. The upper leveling module 511 is provided with an avoidance gap k that matches the saw disc. The glass is cut off based on sawing. Furthermore, the upper cutting component Q also includes a power seat q2 that corresponds to each saw disc one by one and can be adjusted up and down, wherein each saw disc matches a power motor, and the power motor is installed on the power seat q2. That is, each saw disc corresponds to a motor, and the amount of sawing formed can be adjusted. At the same time, the upper cutting component Q also includes a dust collecting pipe q3 corresponding to each avoidance gap k and located above each saw disc, and a negative pressure dust collector q4 connected to multiple dust collecting pipes q3, wherein the bottom of the dust collecting pipe q3 is open, and the debris formed by cutting is adsorbed and collected based on negative pressure. Here, the collection of broken glass is based on the negative pressure dust collector, and the negative pressure dust collector itself has solid-gas separation.
[0047] In some specific embodiments, a plurality of saw discs are divided into at least two rows, and the saw discs in each row rotate in the same and / or opposite directions. Based on the layout of the rotation direction, the magnitude of the lateral force is reduced, thereby maintaining sawing while pushing forward. The saw discs in two adjacent rows are alternately spaced in the width direction of the component. Ensure that the sawing area covers the entire width of the component. In this example, the number of saw discs in the two rows is equal, but of course it can also be unequal.
[0048] As for the back glass removal unit 52, it includes an upper annular pressing belt 520 located at the top, a lower leveling module 521 and a lower cutting module 522 located above the upper annular pressing belt 520, a second leveling channel is formed between the upper annular pressing belt 520 and the lower leveling module 521, and the lower cutting module 522 includes a lower cutting assembly E and a secondary roller brush stripping assembly F located at the discharge end of the second leveling channel and arranged front to back, wherein the lower cutting assembly E includes a plurality of lower cutting tools e1 that form relative intervals in each area and are relatively staggered front to back, and the forces formed by the plurality of lower cutting tools e1 and the secondary roller brush stripping assembly F on the assembly offset each other in the width direction of the assembly, so as to output the battery sheet horizontally forward under the movement of the upper annular pressing belt 520. The specific structural layout is similar to the glass removal mechanism in reference CN202411572231.X.
[0049] In some specific embodiments, the back glass removal unit 52 is located between the preheat treatment unit 50 and the front glass removal unit 51. That is, the back glass layer is removed first, and then the front glass layer is removed. The back glass removal unit 52 and the front glass removal unit 51 are completely independent, and after the back glass is removed, the component enters the front glass removal unit 51 horizontally; or, the back glass removal unit 52 and the front glass removal unit 51 are associated, and when the back glass is removed, the front end of the component enters the first leveling channel, and the rear end of the component is between the secondary roller brush stripping component F and the upper annular pressing belt 520 to complete the secondary roller brush stripping during the motion reception. Here, the removal of the two glass layers can be carried out separately or in association. However, considering the length of the container, the association mode is generally adopted, because in this mode, not only can the installation space be reduced, but the reception and output can also restrain and assist each other, reducing the probability of component offset caused by the secondary roller brush stripping.
[0050] In addition, the preheat treatment unit includes a pretreatment furnace, and the heating temperature formed by the pretreatment furnace is 80-100°C. This temperature mainly softens the glue layer, so that when cutting in the later stage, it is easier to separate the glass from the cell. At the same time, the lower leveling module 521 and the upper leveling module 511 used are conventional shaping seats, such as a pressure plate seat or other mold seats.
[0051] In summary, the implementation process of this embodiment includes the following steps:
[0052] S1, stacking material
[0053] The double-glass modules are stacked and fed into a loading device, and then the double-glass photovoltaic modules are transferred piece by piece to the junction box removal device by a lateral transfer robot;
[0054] S2. Removal of junction box
[0055] After receiving the double-glass module, position adjustment is carried out within the coordinate system formed on the XY axes. At the same time, the wires of the junction box are relatively straightened based on the subsequent movement of the wire-straightening part. Then, the wires are cut close to the box body of the junction box with scissors. Next, the box body is shoveled to remove the junction box. Among them, wire straightening, cutting, and shoveling are located at the same station;
[0056] S3. Removal of the glass layer
[0057] The double-glass module enters the pretreatment furnace horizontally for heating at 80 - 100 °C to soften the adhesive layer. The double-glass module transmitted from the pretreatment furnace enters the second leveling channel with the front side facing up and the back side facing down. Under the transmission of the upper annular pressing belt, the back glass contacts the lower cutting component and the secondary roller brush peeling component in sequence. That is, under the horizontal forward push of the module, the back glass layer is removed by the cooperation of cutting and secondary roller cutting. The module with the back glass layer removed enters the first leveling channel, and the front glass of the module is wedged or clamped by the roller pressing and crushing component to form a wide-width roller pressing type crushing in the corresponding area. At the same time, in cooperation with the lower annular pressing belt, the module is continuously pushed forward until the front glass layer contacts each upper cutting tool. The forces formed by the multiple upper cutting tools and the roller pressing and crushing component on the module cancel each other out in the wide-width direction of the module, so as to remove the front glass layer of the battery cell and horizontally output the battery cell forward.
[0058] In summary, on the one hand, the present invention forms horizontal docking of components and forms divided glass based on the front and back glass removal units, shortening the length required for glass removal, so that the layout of each device is also in the same container to meet the on-site recycling needs of a single container; on the other hand, based on the lateral force offset formed by cutting and secondary roller brushes in glass removal, the lateral force offset formed by cutting and roller crushing, and the leveling of two leveling channels and the pushing of the annular pressing belt, the front and back glass of the components are removed in sequence without offset, and the resulting glass removal rate is high, the damage rate of the battery cells is low, and it is not affected by the deformation or damage of the components, and it is highly practical; on the third aspect, the removal of the two glass layers can be carried out separately or in association, but considering the length of the container, the association mode is generally adopted, because in this mode, not only can the installation space be reduced, but the reception and output can also be mutually restrained and assisted, reducing the probability of component offset caused by secondary roller brush peeling; on the fourth aspect, based on the contact and poking of the roller nails, not only the glass layer is better broken to reduce the difficulty of sawing, but also lateral slippage is avoided (because the glass surface is very smooth) to assist transmission, and at the same time, the contact and poking formed based on the inclination bring about the benefits The advantages are: 1. Decomposing the force to both sides to avoid the pressure concentration caused by the roller nail contacting the glass at the moment, which may cause the components to jam; 2. Effectively coordinating the stress generated by sawing to form mutually offset lateral forces, so that the surface glass can be removed smoothly; in addition, based on the dislocation or alignment distribution, inclined forces in different directions are formed, and the broken area formed is also increased (especially when the dislocation distribution is used); the fifth aspect is based on sawing to cut off the glass, and each saw disc corresponds to a motor, and the amount of sawing formed can be adjusted. At the same time, the negative pressure dust collector collects the broken glass, and the negative pressure dust collector itself has solid-gas separation. In addition, based on the layout of the rotation direction, the size of the lateral force is reduced, so as to maintain the sawing during the forward push. At the same time, the saw disks in the two adjacent rows are alternately spaced in the direction of the component width to ensure that the sawing area covers the entire component width. In the sixth aspect, according to actual needs, after using this equipment on site, both framed double-glass components and frameless double-glass components can be used to recycle battery cells, increasing the practicality of the equipment. In addition, the heating temperature formed by the pretreatment furnace is 80-100°C. This temperature mainly plays the role of softening the glue layer, so that in the subsequent cutting, it is more labor-saving to separate the glass from the battery cell.
[0059] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
