Description

Technical Field

[0001] The invention belongs to the technical field of double-glass component recycling, and in particular relates to a single-container double-glass on-site recycling device, and also relates to a single-container double-glass on-site recycling process. Background Art

[0002] Double-glass photovoltaic modules (double-glass modules for short) mainly include solar cells, front glass layers, back glass layers, and junction boxes. The on-site recycling generally includes loading stations, junction box removal stations, front glass layer removal stations, back glass layer removal stations, and unloading stations. If the double-glass photovoltaic modules are double-glass photovoltaic modules with frames, a frame removal station needs to be added. Therefore, whether it is a frameless double-glass photovoltaic module or a framed double-glass photovoltaic module, it is obvious that they cannot be arranged in the same container (due to the length limit of the container). However, in actual operation, there are still the following technical defects:

[0003] 1) Due to the length limitation of the container, two or more sections are basically required for assembly. Although this can reduce the cost of on-site recycling, the use of multiple sections has limitations in both equipment transportation and site restrictions, and it is impossible to achieve the required low-cost, fast and adaptable battery cell recycling process;

[0004] 2) As for glass removal, 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 glass thickness and cannot meet the needs of on-site use. Moreover, once the component itself is deformed, it is difficult to perform milling with equal thickness. The resulting glass removal rate is low and the damage rate of the battery cell will increase. As for the sequential removal of glass, the front stripping cannot maintain a flat output, and the component direction needs to be flipped after the front stripping is completed, and the same stripping action is performed to complete the secondary stripping. This implementation method not only occupies a large space, but also requires flipping and relative shaping and flattening. Therefore, the final glass removal rate is unstable, and it is also difficult to achieve the desired glass removal quality for deformed components.

[0005] 3) For double-glass modules, whether they are framed double-glass modules or frameless double-glass modules, recycling equipment is selected based on product characteristics. Therefore, the functions of the recycling equipment are relatively simple. That is, there is no optional or universal recycling and processing equipment on the market that can be accommodated in the same container. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved single container double-glass on-site recycling device.

[0007] At the same time, the present invention also relates to a single container double-glass on-site recycling process.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A single container double glass on-site recycling device, comprising a container, a loading device, a junction box removal device, and a glass removal device, wherein the glass removal device comprises a front glass removal unit and a back glass removal unit, in particular, each device is located in the same container, the glass removal device also comprises a preheating treatment unit, the double glass assembly is kept with the front side facing upward and the back side facing downward and is transferred to the preheating treatment unit and the front glass removal unit and the back glass removal unit, wherein the front glass removal unit comprises a lower annular pressing belt located at the bottom, an upper leveling module and an upper cutting module located above the lower annular pressing belt, a first leveling channel is formed between the lower annular pressing belt and the upper leveling module, the upper cutting module comprises a roller crushing assembly and an upper cutting assembly located at the inlet and outlet ends of the first leveling channel, the roller crushing assembly can wedge or jam into the front glass to form a wide-width roller crushing in the corresponding area, and the upper cutting assembly comprises a relative pressure module for each area A plurality of upper cutting tools are spaced apart and relatively staggered front and back, and the forces exerted on the components by the plurality of upper cutting tools and the roller crushing assembly offset each other in the width direction of the components, so that the battery cells can be horizontally output forward when the lower annular pressing belt moves; the back glass removal unit comprises an upper annular pressing belt located at the top, a lower leveling module and a lower cutting module located above the upper annular pressing belt, a second leveling channel is formed between the upper annular pressing belt and the lower leveling module, the lower cutting module comprises a lower cutting assembly and a secondary roller brush stripping assembly located at the discharge end of the second leveling channel and arranged front to back, wherein the lower cutting assembly comprises a plurality of lower cutting tools which are relatively spaced apart and relatively staggered front and back to form each area, and the forces exerted on the components by the plurality of lower cutting tools and the secondary roller brush stripping assembly offset each other in the width direction of the components, so that the battery cells can be horizontally output forward when the upper annular pressing belt moves.

[0010] Preferably, the back glass removal unit is located between the preheating unit and the front glass removal unit, that is, the back glass layer is removed first, and then the front glass layer is removed.

[0011] According to a specific implementation and preferred aspect of the present invention, the back glass removal unit and the front glass removal unit are completely independent, and after the back glass is removed, the component enters the front glass removal unit horizontally; or, the back glass removal unit and the front glass removal unit 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 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 output can also restrain and assist each other, reducing the probability of component offset caused by the secondary roller brush stripping.

[0012] According to another specific implementation and preferred aspect of the present invention, the roller crushing assembly includes a roller body extending along the width direction of the assembly, and a plurality of roller pins distributed around the roller body, wherein the roller pins contact the glass during the self-rotation of the roller body, the glass is crushed and a force in the lateral and forward directions is formed to assist the translational cutting of the assembly. 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.

[0013] 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.

[0014] 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.

[0015] According to another specific implementation and preferred aspect of the present invention, the inclination direction of each two adjacent groups of roller pins is respectively toward the two ends of the roller body, and the two adjacent groups of roller pins 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).

[0016] 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.

[0017] Furthermore, the upper cutting assembly also includes a power seat corresponding to each saw disc and capable of adjusting up and down movement, wherein each saw disc matches a power motor, and the power motor is installed on the power seat. That is, each saw disc corresponds to a motor, and the amount of sawing formed can be adjusted.

[0018] According to another specific implementation and preferred aspect of the present invention, the upper cutting assembly further includes a dust collecting pipe corresponding to each avoidance notch and located above each saw disc, and a negative pressure dust collector connected to the plurality of dust collecting pipes, wherein the bottom of the dust collecting pipe 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.

[0019] Preferably, the 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 size of the lateral force is reduced, thereby maintaining sawing during forward pushing.

[0020] Furthermore, the saw blades in two adjacent rows are alternately spaced in the width direction of the component to ensure that the sawing area covers the entire width of the component.

[0021] In addition, the single container double-glass on-site recycling equipment also includes a frame removal device arranged between the junction box removal device and the glass removal device, and the loading device, the junction box removal device, the frame removal device, and the glass removal device are arranged in the same container in sequence. In short, according to actual needs, after this equipment is used on-site, both framed double-glass modules and frameless double-glass modules can be recycled, increasing the practicality of the equipment.

[0022] Preferably, the preheat treatment unit includes a pretreatment furnace, and 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 the glass can be relatively separated from the battery cell more easily during subsequent cutting.

[0023] Another technical solution of the present invention is: a single container double glass on-site recycling process, which adopts the above-mentioned single container double glass on-site recycling equipment and includes the following steps:

[0024] S1, stacking material

[0025] 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;

[0026] S2. Removal of junction box

[0027] After receiving the double-glass module, the position is adjusted in the coordinate system formed by the XY axis. At the same time, the wires of the junction box are relatively straightened based on the movement of the wire straightening part. Then, the scissors are close to the box body of the junction box to cut it, and then the box body is clamped to remove the junction box. The straightening, cutting and clamping are located in the same station.

[0028] S3. Removal of glass layer

[0029] The double-glass component enters the pretreatment furnace horizontally and is heated at 80-100° to soften the glue layer, and the double-glass component transmitted from the pretreatment furnace is kept facing up and the back side facing down to enter the second leveling channel, and under the transmission of the upper annular pressing belt, the back glass contacts the lower cutting component and the secondary roller brush stripping component in sequence, that is, when the component is pushed forward horizontally, the back glass layer is removed by the cooperation of cutting and secondary rolling, and the component with the back glass layer removed enters the first leveling channel, and the front glass is wedged or stuck in the roller crushing component to form a wide-width roller crushing in the corresponding area, and at the same time, the component is continuously pushed forward in cooperation with the lower annular pressing belt until it contacts the front glass layer and contacts each upper cutting tool, and the forces formed on the component by the multiple upper cutting tools and the roller crushing components offset each other in the wide direction of the component, so as to remove the front glass layer of the battery cell and output the battery cell horizontally forward.

[0030] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0031] In the on-site recycling of existing double-glass components, based on the length limit of the container, two or more sections are basically required for assembly. Although the cost of on-site recycling can be reduced, the use of multiple sections has limitations in both equipment transportation and site restrictions, and the required low-cost, fast and adaptable battery cell recycling processing cannot be achieved; for glass removal, some manufacturers perform simultaneous glass removal on the front and back sides, while others remove the glass on the front and back sides in sequence. For 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. Once the component itself is deformed, it is difficult to perform milling of equal thickness, resulting in a low glass removal rate and an increase in the damage rate of the battery cells. When removing the glass in sequence, the previous stripping cannot maintain a flat output, and the component direction needs to be flipped after the previous stripping is completed, and the same stripping action needs to be performed to complete the secondary stripping. This implementation method not only takes up a large space, but also requires flipping and relative shaping and flattening. Therefore, the final glass removal rate is unstable and... It is also difficult to achieve the desired glass removal quality for deformed components; for double-glass components, whether they are framed double-glass components or frameless double-glass components, the recycling equipment is selected according to the product characteristics. Therefore, the function of the recycling equipment is relatively simple, that is, there is no optional or universal recycling and processing equipment on the market that can also be accommodated in the same container, and the present invention designs the structure of the single-container double-glass on-site recycling equipment as a whole, and cleverly solves the shortcomings and defects of the prior art. After using the single-container double-glass on-site recycling equipment, first, the double-glass components are stacked and fed into the feeding device, and then the double-glass photovoltaic components are transferred to the junction box removal device piece by piece by the transverse transfer robot; then, after receiving the double-glass components, the position is adjusted in the coordinate system formed by the XY axis, and at the same time, the wires of the junction box are relatively straightened based on the movement of the wire straightening part, and then the scissors are close to the box body of the junction box to cut it, and then the box body is clamped and shoveled to remove the junction box, wherein the straightening, cutting, and clamping are located at the same station;Finally, the double-glass component enters the pretreatment furnace horizontally to be heated at 80-100° to soften the glue layer, and the double-glass component transmitted from the pretreatment furnace is kept facing up and the back side facing down to enter the second leveling channel, and under the transmission of the upper annular pressing belt, the back glass contacts the lower cutting component and the secondary roller brush stripping component in sequence, that is, when the component is pushed forward horizontally, the back glass layer is removed by the cooperation of cutting and secondary rolling, and the component with the back glass layer removed enters the first leveling channel, and the roller crushing component is wedged or stuck into the front glass to form a wide roller crushing in the corresponding area, and at the same time, the lower annular pressing belt is cooperated to push the component forward continuously until it contacts the front glass layer and contacts the upper cutting tools, and the forces formed on the component by multiple upper cutting tools and roller crushing components are The components offset each other in the width direction to remove the front glass layer of the cell and output the cell horizontally forward. Therefore, compared with the prior art, the present invention, on the one hand, forms a horizontal docking of components and forms glass in batches based on the front and back glass removal units, shortening the length required for glass removal, thereby arranging each device in the same container to meet the on-site recycling needs of a single container; on the other hand, based on the offset of the lateral force formed by cutting and secondary roller brushes in glass removal, the offset of the lateral force formed by cutting and roller crushing, and the leveling of the two leveling channels and the pushing of the annular pressing belt, the components can be removed from the front and back glass in sequence without offset, resulting in a high glass removal rate and a low cell damage rate. At the same time, it is not affected by component deformation or damage, and has strong practicality. ; BRIEF DESCRIPTION OF THE DRAWINGS

[0046] like Figures 1 to 7 As shown, the single container double-glass on-site recycling equipment of this embodiment includes a container 1, a loading device 2, a junction box removal device 3, a frame removal device 4, and a glass removal device 5 arranged in sequence in the same container 1. In short, according to actual needs, after the equipment is used on-site, both framed double-glass modules and frameless double-glass modules can be recycled, thereby increasing the practicality of the equipment.

[0047] Specifically, the structures of the container 1, the loading device 2, the junction box removal device 3, and the frame removal device 4 are the same as the structures involved in CN202411572231.X, which will not be described in detail here. At the same time, the glass removal device 5 used includes a preheating treatment unit 50, a front glass removal unit 51, and a back glass removal unit 52, wherein the back glass removal unit 52 is the same as the glass removal mechanism in CN202411572231.X, which will not be described in detail here. That is, compared with CN202411572231.X, the main differences between this application and CN202411572231.X are: 1. The double-glass components of the objects to be recycled; 2. A continuous and sequential glass removal method is adopted to strip the glass, and the front glass removal unit 51 and the back glass removal unit 52 used are similar and different; 3. The specific stripping process formed is different.

[0048] The specific differences are as follows:

[0049] In the present application, the front glass removal unit 51 includes a lower annular pressing belt 510 located at the bottom, an upper leveling module 511 and an upper cutting module 512 located above the lower annular pressing belt 510, wherein a first leveling channel is formed between the lower annular pressing belt 510 and the upper leveling module 511, and the upper cutting module 512 includes a roller crushing assembly G and an upper cutting assembly Q located at the inlet and outlet ends of the first leveling channel, the roller crushing assembly G can wedge or jam into the front glass to form a wide-width roller crushing in the corresponding area, and the upper cutting assembly Q includes a plurality of upper cutting tools q1 that form relative intervals between each area and are relatively staggered front and back, and the forces exerted on the assembly by the plurality of upper cutting tools q1 and the roller crushing assembly G offset each other in the wide direction of the assembly, so that the battery cell is output horizontally forward when the lower annular pressing belt 510 moves.

[0050] 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 translational cutting of the assembly. 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 force in different directions is 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 nail is less than the thickness of the glass.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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 it is easier to separate the glass from the cell when cutting in the later stage. 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.

[0056] In summary, the implementation process of this embodiment includes the following steps:

[0057] S1, stacking material

[0058] 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;

[0059] S2. Removal of junction box

[0060] After receiving the double-glass module, the position is adjusted in the coordinate system formed by the XY axis. At the same time, the wires of the junction box are relatively straightened based on the movement of the wire straightening part. Then, the scissors are close to the box body of the junction box to cut it, and then the box body is clamped to remove the junction box. The straightening, cutting and clamping are located in the same station.

[0061] S3. Removal of glass layer

[0062] The double-glass component enters the pretreatment furnace horizontally and is heated at 80-100° to soften the glue layer, and the double-glass component transmitted from the pretreatment furnace is kept facing up and the back side facing down to enter the second leveling channel, and under the transmission of the upper annular pressing belt, the back glass contacts the lower cutting component and the secondary roller brush stripping component in sequence, that is, when the component is pushed forward horizontally, the back glass layer is removed by the cooperation of cutting and secondary rolling, and the component with the back glass layer removed enters the first leveling channel, and the front glass is wedged or stuck in the roller crushing component to form a wide-width roller crushing in the corresponding area, and at the same time, the component is continuously pushed forward in cooperation with the lower annular pressing belt until it contacts the front glass layer and contacts each upper cutting tool, and the forces formed on the component by the multiple upper cutting tools and the roller crushing components offset each other in the wide direction of the component, so as to remove the front glass layer of the battery cell and output the battery cell horizontally forward.

[0063] 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. The sixth aspect is that according to actual needs, after using this equipment on site, both the double-glass components with frames and the double-glass components without frames can be used to recycle the battery cells, increasing the practicality of the equipment. In addition, the heating temperature formed by the pretreatment furnace is 80~100℃. 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 cells.
