Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of photovoltaic, and particularly relates to a general single-glass module and double-glass module adhesive film layer removing device. BACKGROUND
[0002] A photovoltaic module is a power generation device that can generate direct current when exposed to sunlight, which is composed of thin solid photovoltaic cells made of almost all semiconducting materials (such as silicon), and more than 90% of the materials can be recycled, which has considerable recycling value and high economic profit. Therefore, recycling the retired photovoltaic module can not only alleviate the problem of shortage of raw materials for photovoltaic equipment to a certain extent, but also effectively reduce the pollution to the environment.
[0003] At present, photovoltaic modules can be divided into single-glass modules and double-glass modules according to the structure of photovoltaic cells. The single-glass module mainly includes a back plate layer, a cell piece layer, an adhesive film layer and a glass layer which are stacked in sequence. The double-glass module mainly includes a lower glass layer, a lower adhesive film layer, a cell piece layer, an upper adhesive film layer and an upper glass layer which are stacked in sequence. The recycling of photovoltaic modules mainly includes the disassembly and recycling of each layer of materials. When the upper glass layer is peeled off, the existing removing device mainly includes a press roller and a cutter which are distributed above the single-glass module or the double-glass module along the transmission direction of the single-glass module or the double-glass module. When the single-glass module or the double-glass module is horizontally transmitted, the press roller is pressed on the surface of the single-glass module or the double-glass module, and the cutter synchronously removes the adhesive film layer.
[0004] However, in the actual recycling process, the existing technology has the following defects:
[0005] 1. In the process of removing the adhesive film of the single-glass module, the back plate layer at the bottom of the single-glass module is not rigid enough, and there is a gap between the pressing position formed by the press roller and the scraping position formed by the cutter. Therefore, after a certain area of the adhesive film layer is removed, one end of the single-glass module to be removed will gradually be out of the pressing of the press roller and lose the limitation, and with the further transmission of the single-glass module, the end of the single-glass module out of the pressing will easily deform (such as upwarping or downward bending) under the action of the removing force of the cutter and the horizontal transmission force, which will make the contact between the cutter and the adhesive film layer unstable, and thus easily cause the depth of the scraping of the cutter to be too deep to damage the cell piece layer or the back plate layer, or the depth of the scraping of the cutter to be too shallow to completely remove the adhesive film layer;
[0006] 2. Although the bottom layer of the existing double-glass module is glass which has a certain rigidity, the double-glass module to be recycled cannot guarantee flatness. When the double-glass module passes through the cutter, it is easy to cause excessive scraping to damage the cell piece or incomplete scraping to leave residual adhesive film;
[0007] 3. The existing technology cannot meet the general requirements of removing the adhesive film layer of single-glass assemblies and double-glass assemblies due to the structural differences between single-glass assemblies and double-glass assemblies. SUMMARY
[0008] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide an improved universal single-glass assembly and double-glass assembly adhesive film layer removal device.
[0009] To solve the above technical problems, the technical solutions adopted by the present application are as follows:
[0010] A universal single-glass assembly and double-glass assembly adhesive film layer removal device comprises a conveying line, a first station, a second station and a third station which are sequentially separated based on the conveying line and can be raised and lowered, adhesive film removal cutters which are distributed in each station and located above the conveying line, and a pressing assembly which is correspondingly distributed based on the adhesive film removal cutters, wherein the first station and the third station form a single-glass adhesive film removal group, the adhesive film removal cutters of the first station and the third station have multiple cutters, the multiple adhesive film removal cutters are sequentially distributed in the length direction of the single-glass assembly, the cutter heads of the multiple adhesive film removal cutters are staggered and correspondingly form multiple gouging areas of the adhesive film layer in the width direction of the single-glass assembly, the single-glass assembly entering the first station or the third station is divided into a first adhesive film removal area and a second adhesive film removal area in the length direction of the single-glass assembly based on the position of the pressing assembly, the second station forms a double-glass adhesive film removal group, the adhesive film removal cutters of the second station form a gouging area of the adhesive film layer along the width direction of the double-glass assembly, the double-glass assembly entering the second station removes the adhesive film layer in a covering manner based on the cooperation of the pressing assembly and the adhesive film removal cutters, and the single-glass adhesive film removal group and the double-glass adhesive film removal group are switched by the cooperation of the raising and lowering of the first station, the second station and the third station to remove the adhesive film of the single-glass assembly and the double-glass assembly, and in the adhesive film removal of the single-glass assembly, the adhesive film layer removal of the first adhesive film removal area and the second adhesive film removal area is performed in the first station and the third station in sequence and in reverse.
[0011] Preferably, the first station and the third station are kept aligned and are set to be raised and lowered synchronously. Here, the synchronous raising and lowering adjustment is to meet the gouging of the first adhesive film removal area and the second adhesive film removal area under the same gouging condition, so as to ensure the uniform removal of the adhesive film.
[0012] According to a specific implementation and preferred aspect of the present application, each adhesive film removal cutter forms a gouging channel with the conveying line, each pressing assembly comprises a pressing unit and a brushing unit, and during gouging, the single-glass assembly or the double-glass assembly passes through each gouging channel based on the pressing of the pressing unit, and the brushing unit simultaneously presses the single-glass assembly or the double-glass assembly and is used to sweep away the formed adhesive film scraps. Here, the adhesive film scraps are swept away from the surface of the assembly in time, avoiding residues.
[0013] Preferably, the pressing unit can form a matching transmission power synchronously with the transmission of the conveying line, or the pressing unit elastically contacts the surface of the single-glass assembly or the double-glass assembly as the single-glass assembly or the double-glass assembly is transmitted.
[0014] Preferably, the transmission line comprises a plurality of transmission rollers arranged side by side along the length direction of the single-glass assembly or the double-glass assembly, the pressing points formed by the pressing unit and the brushing unit on the single-glass assembly or the double-glass assembly are vertically aligned with the supporting points formed by the corresponding transmission rollers on the single-glass assembly or the double-glass assembly. In this way, the stress on the upper and lower surfaces of the single-glass assembly or the double-glass assembly is uniform, and the deformation problem is reduced.
[0015] Preferably, in the first station, the pressing unit comprises at least one or more first pressing rollers arranged on one side of the feeding end of each scraping channel, and the brushing unit comprises at least one or more first brushing rollers arranged on one side of the discharging end of the last scraping channel.
[0016] Specifically, in the orthographic projection on the horizontal plane, the distance between each adhesive-removing film cutter and the center of the adjacent first pressing roller is equal. In this way, the lengths of each scraping area are equal.
[0017] Preferably, in the third station, the pressing unit comprises at least one or more second pressing rollers arranged on one side of the feeding end and the discharging end of each scraping channel, and the brushing unit comprises a plurality of second brushing rollers arranged on one side of the first and the last scraping channels. In this way, the surface adhesive film fragments of the single-glass assembly are cleaned in the forward and reverse movements in the third station, and the residual adhesive film does not affect the scraping of the cutters.
[0018] Preferably, in the second station, the pressing unit comprises a pressing component, wherein the pressing component has a plurality of abutting ends arranged side by side along the width direction of the double-glass assembly and maintaining a downward elastic movement trend, and the plurality of abutting ends abut on the surface of the double-glass assembly synchronously when the double-glass assembly passes below the pressing component. In this way, the pressing component can adaptively flatten and press according to the flatness of the surface of the double-glass assembly, and the excessive pressure does not cause the damage of the bottom glass layer.
[0019] Specifically, the pressing component comprises a connecting seat, a plurality of pressing modules arranged on the connecting seat and spliced in the width direction of the double-glass assembly, and an elastic member, wherein each pressing module can be flipped up and down in the width direction of the double-glass assembly and forms an abutting end from the lower part, and the elastic member abuts between the upper part of the pressing module and the connecting seat. In this way, the structure is simple, and the assembly and implementation are convenient.
[0020] Further, the pressing unit further comprises a supporting component arranged on the transmission path of the double-glass assembly, and the supporting component forms a supporting surface flush with the transmission surface formed by the transmission line from the top, wherein the supporting surface is vertically aligned with the plurality of abutting ends. In this way, the bottom of the double-glass assembly is supported, and the probability of glass breakage is further reduced.
[0021] According to another specific implementation and preferred aspect of the present application, the adhesive-removing film cutter comprises a cutter roller and a plurality of cutters arranged side by side around the cutter roller, and the cutting depth of each cutter is equal to the thickness of the adhesive film layer during scraping.
[0022] According to still another specific implementation and preferred aspect of the present application, the cutting-off device further comprises an auxiliary component disposed between the first station and the second station, the auxiliary component comprising a U-shaped auxiliary module located above the corresponding transmission roller and having an opening downward, a lifting power member driving the lifting movement of the auxiliary module, and the auxiliary module is lowered to squeeze the film scraps remaining on the transmission roller out of the space between the adjacent transmission rollers. Here, the large area of film scraps remaining on the transmission roller is avoided to affect the subsequent transmission of the single glass assembly or the double glass assembly.
[0023] In addition, the cutting-off device further comprises a film recovery station disposed below the transmission line and corresponding to the first, second and third stations for recovering the film scraps.
[0024] Thanks to the implementation of the above technical solutions, the present application has the following advantages compared with the prior art:
[0025] The prior art in single-glass adhesive film removal, due to the insufficient rigidity of the backboard layer of the single-glass assembly bottom layer, and the inevitable gap between the roller pressing position formed by the pressure roller and the scraping position formed by the cutter, after removing the adhesive film layer in a certain area, the end of the single-glass assembly to be removed will inevitably gradually separate from the roller pressing and lose the restriction, and with the further transmission of the single-glass assembly, the end of the single-glass assembly losing the roller pressing restriction is easy to deform (such as upwarping or downward bending) under the action of the scraping force of the cutter and the horizontal transmission force, causing unstable contact between the cutter and the adhesive film layer, thus easily leading to excessive scraping depth of the cutter and causing damage to the battery piece layer or even the backboard layer, or the scraping depth of the cutter is too shallow, causing the residual area of the adhesive film layer to be unable to be completely removed; although the existing double-glass assembly has a certain rigidity of the bottom layer, the recovered double-glass assembly cannot guarantee flatness, and the double-glass assembly is easy to be damaged by excessive scraping or not completely scraped when passing through the cutter; based on the structural differences between the single-glass assembly and the double-glass assembly, the prior art cannot meet the general requirements of adhesive film layer removal for single-glass assemblies and double-glass assemblies. The structure of the general single-glass assembly and double-glass assembly adhesive film layer removal device is designed as a whole, and the deficiencies and defects of the prior art are ingeniously solved. After adopting the general single-glass assembly and double-glass assembly adhesive film layer removal device, when removing the adhesive film layer of the single-glass assembly, the second station is lifted, the first and third stations are lowered to switch to the single-glass adhesive film removal group, the single-glass assembly passes through the first station and the third station in turn along the transmission line, and the position of the single-glass assembly based on the lower pressing assembly of the first and third stations is divided into a first adhesive film removal area and a second adhesive film removal area in the length direction, wherein when the single-glass assembly enters the first station, the multiple scraping areas formed by the multiple adhesive film removal cutters of the first station remove the adhesive film layer of the first adhesive film removal area, and when the single-glass assembly enters the third station, the single-glass assembly moves reversely and the multiple scraping areas formed by the multiple adhesive film removal cutters of the third station remove the adhesive film layer of the second adhesive film removal area; when removing the adhesive film layer of the double-glass assembly, the first and third stations are lifted, the second station is lowered to switch to the double-glass adhesive film removal group, the scraping area formed by the adhesive film removal cutter of the second station covers the adhesive film layer along the width direction of the double-glass assembly, and the double-glass assembly entering the second station removes the adhesive film layer in a cooperative covering manner based on the lower pressing assembly and the adhesive film removal cutter. Therefore, compared with the prior art, on the one hand, the first, second and third stations cooperate to form two working modes to meet the removal requirements of the adhesive film layer of the single-glass assembly and the double-glass assembly respectively, realizing general function; on the other hand, based on the layout of the lower pressing assembly of the first and third stations, the adhesive film layer of the single-glass assembly is partitioned, multiple scraping areas covering the adhesive film layer are formed by multiple cutters, the removal rate of the adhesive film layer is effectively improved, and the two partitions of the adhesive film layer are always removed in turn and reversely under the lower pressing restriction; in addition, based on the cooperation of the lower pressing and scraping of the second station, the adhesive film layer of the double-glass assembly is removed once.

[0038] like Figures 1 to 5 As shown, the general-purpose encapsulant removal device for single-glass and double-glass modules involved in this embodiment includes a transmission line 1, a first station 2, a second station 3, a third station 4, an encapsulant removal tool 5, and a pressing component 6.
[0039] Specifically, the transmission line 1 includes multiple transmission rollers 10 arranged side by side at intervals along the Z-length direction of the component. Both single-glass and double-glass components are horizontally transported from the encapsulated layer upwards along the multiple transmission rollers 10.
[0040] In this example, the first station 2, the second station 3, and the third station 4 are sequentially separated by the transmission line 1 to form a vertical movement. The first station 2 and the third station 4 form a single-glass adhesive removal group, and the second station 3 forms a double-glass adhesive removal group. The single-glass adhesive removal group and the double-glass adhesive removal group are switched based on the vertical movement of the first station 2, the second station 3, and the third station 4 to remove the adhesive from the single-glass module and the double-glass module.
[0041] In some specific embodiments, the first station 2, the second station 3, and the third station 4 all employ existing lifting devices to achieve lifting movements, with the first station 2 and the third station 4 kept aligned and raised and lowered synchronously. Here, synchronous lifting adjustment is used to ensure uniform removal of the adhesive film by scraping the first and second adhesive film removal areas under the same scraping conditions.
[0042] In this example, the encapsulant removal cutters 5 are distributed at each station and located above the transmission line 1. There are two encapsulant removal cutters 5 at the first station 2 and the third station 4, and the two encapsulant removal cutters 5 are distributed sequentially along the length of the single-glass module. The cutter heads of the two encapsulant removal cutters 5 are staggered and form multiple scraping areas q0 covering the encapsulant layer in the width direction of the single-glass module. There is one encapsulant removal cutter 5 at the second station 3, which forms a scraping area q0 covering the encapsulant layer along the width direction of the double-glass module.
[0043] In some specific embodiments, the adhesive film removal tool 5 includes a cutter roller 50 and multiple planer blades (not shown in the figure, but easily understood) distributed circumferentially around the cutter roller 50. During the scraping process, the cutting depth of each planer blade is equal to the thickness of the adhesive film layer, and the planer blades are commercially available products. That is, in the first and third stations, the multiple planer blades on the two cutter rollers 50 are staggered in the length direction of the single-glass module, and in the second station, the scraping width of the planer blades covers the width of the double-glass module.
[0044] In this example, the pressing component 6 is distributed according to the adhesive removal tool 5. That is, the single-glass modules entering the first station 2 or the third station 4 are divided into a first adhesive removal area q1 and a second adhesive removal area q2 in the length direction of the single-glass module based on the position of the pressing component 6. In the adhesive removal of the single-glass module, the first station 2 and the third station 4 remove the adhesive film layer of the first adhesive removal area q1 and the second adhesive removal area q2 in sequence and in reverse. In the adhesive removal of the double-glass module, the double-glass module entering the second station 3 achieves one-time removal of the adhesive film layer based on the cooperative coverage of the pressing component 6 and the adhesive removal tool 5.
[0045] In some specific embodiments, each adhesive film removal cutter 5 forms a scraping channel t with the transmission line 1. Each pressing component 6 includes a pressing unit 60 and a brushing unit 61. During scraping, the single-glass or double-glass component is pressed down through each scraping channel t by the pressing unit 60, and the brushing unit 61 simultaneously presses down on the single-glass or double-glass component and is used to remove the formed adhesive film fragments. Here, it is ensured that the adhesive film fragments are swept away from the component surface in a timely manner to avoid residue.
[0046] For ease of implementation, the pressing unit 60 can synchronously generate matching transmission power with the transmission line 1, or elastically abut against the surface of the single-glass or double-glass module during transmission. The pressing points formed by the pressing unit 60 and the brushing unit 61 on the single-glass or double-glass module are vertically aligned with the support points formed by the corresponding transmission roller 10 on the single-glass or double-glass module. This ensures uniform force on the upper and lower surfaces of the module, reducing deformation issues.
[0047] In some specific embodiments, in the first station 2, the pressing unit 60 includes at least one or more first pressure rollers 601 correspondingly arranged on one side of the feeding end of each shovel channel t. The two first pressure rollers 601 located on one side of the feeding end of the first shovel channel t are power rollers, capable of rotating synchronously with the transmission roller 10 and clamping the single-glass module in the direction of the shovel channel t to meet the transmission power requirements of the single-glass module passing through the shovel channel t. The first pressure roller 601 located between the two shovel channels t is a follower roller, which rotates synchronously with the transmission of the single-glass module when rolling on its surface. The brushing unit 61 includes at least one or more first brush rollers 611 arranged on one side of the discharge end of the last shovel channel t. In the orthographic projection on the horizontal plane, the center distance between each adhesive removal cutter 5 and the adjacent first pressure roller 601 is equal, ensuring that the lengths of the misaligned shovel zones are equal.
[0048] In the third station 4, the pressing unit 60 includes at least one or more second pressure rollers 602 correspondingly arranged on one side of the feed end and discharge end of each scraping channel t. During reverse scraping, the two second pressure rollers 602 located on the feed end side of the last scraping channel t are power rollers, which can rotate synchronously with the transmission roller 10 and clamp the single-glass module in the direction of the scraping channel t to meet the transmission power requirements of the single-glass module passing through the scraping channel t. The second pressure roller 602 located between the two scraping channels t is a follower roller, which rotates synchronously with the transmission of the single-glass module when rolling on the surface of the single-glass module. The brushing unit 61 includes at least multiple second brush rollers 612 arranged on one side of the first and last scraping channels t. Here, it is ensured that the surface film fragments of the module are cleaned during both forward and reverse movements in the third station to avoid residues affecting the scraping of the tool.
[0049] It should be noted that when the single-glass module enters the third station 4, the single-glass module first moves forward to the side of the feed end of the last scraping channel t, and then performs the removal of the adhesive layer in the second adhesive removal zone q2 based on the driving reverse motion of the corresponding second pressure roller 602 and the transmission line 1.
[0050] In the second station 3, the pressing unit 60 includes a third pressure roller 603 and a pressing component 604 arranged sequentially along the length of the double-glass module. The third pressure roller 603 is a power roller, and the pressing component 604 has multiple contact ends d arranged side by side along the width of the double-glass module and maintaining a downward elastic movement tendency. When the double-glass module moves forward and passes under the pressing component 604, the multiple contact ends d simultaneously abut against the surface of the double-glass module. The brushing unit 61 includes at least one or more third brush rollers 613 arranged on one side of the discharge end of the scraping channel t.
[0051] In some specific embodiments, the pressing component 604 includes a connecting seat z, a plurality of pressing modules k arranged on the connecting seat z and spliced together in the width direction of the double-glass assembly, and an elastic element j. Each pressing module k is capable of rotating up and down around the width direction of the double-glass assembly and forms an abutting end d from the bottom. The lower part of each pressing module k extends obliquely from top to bottom towards the feed end of the scraping channel t. The elastic element j abuts between the upper part of the pressing module k and the connecting seat z. Here, the structure is simple and easy to assemble and implement.
[0052] Furthermore, the pressing unit 60 also includes a support member 605 disposed on the transmission path of the double-glass module. The support member 605 forms a support surface from the top that is flush with the transmission surface formed by the transmission line 1, wherein the support surface is vertically aligned with the plurality of contact ends d. Here, support is ensured at the bottom of the double-glass module, further reducing the probability of glass breakage.
[0053] In this example, the removal device also includes an auxiliary component 7 disposed between the first station 2 and the second station 3. The auxiliary component 7 includes a U-shaped auxiliary module 70 located above the corresponding transfer roller 10 with its opening facing downwards, and a lifting power component 71 that drives the auxiliary module 70 to move up and down. As the auxiliary module 70 moves downwards, it squeezes out the film debris stuck on the transfer roller 10 from the space between adjacent transfer rollers. This avoids large areas of film debris remaining on the transfer rollers, which could affect the subsequent transfer of single-glass or double-glass modules.
[0054] In addition, the removal device also includes a film recycling station (not shown in the figure, but easy to imagine) located below the conveyor line 1 and corresponding to the first, second and third stations, and used to recycle film fragments. The conveyor line 1 has unloading plates that extend downwards from top to bottom on opposite sides, and the swept film fragments fall down along the unloading plates into the film recycling station.
[0055] In summary, after adopting this universal single-glass module and double-glass module encapsulant layer removal device, when removing the encapsulant layer of the single-glass module, the second station is raised, and the first and third stations are lowered to switch to the single-glass encapsulant removal group. The single-glass module passes through the first and third stations sequentially along the conveyor line. Based on the position of the pressed module at the first and third stations, the single-glass module is divided into a first encapsulant removal area and a second encapsulant removal area along its length. When the single-glass module enters the first station, the multiple scraping areas formed by the multiple encapsulant removal tools at the first station remove the first encapsulant layer. When removing the encapsulant layer in the encapsulant area, the single-glass module moves in the reverse direction and the encapsulant layer in the second encapsulant removal area is removed by multiple scraping zones formed by multiple encapsulant removal tools in the third station. When removing the encapsulant layer of the double-glass module, the first and third stations are raised and the second station is lowered to switch to the double-glass encapsulant removal group. The encapsulant removal tools in the second station form a scraping zone that covers the encapsulant layer along the width direction of the double-glass module. The double-glass module entering the second station removes the encapsulant layer in a comprehensive manner based on the cooperation of the pressed module and the encapsulant removal tools. Therefore, compared with the prior art, this invention, on the one hand, forms two working modes through the lifting and lowering cooperation of the first, second, and third workstations, respectively meeting the removal requirements of the encapsulant layer for single-glass and double-glass modules, achieving universal functionality; on the other hand, based on the downward pressure module layout of the first and third workstations, the encapsulant layer of the single-glass module is divided into sections, with multiple cutters forming multiple scraping zones covering the encapsulant layer, ensuring that the two sections of the encapsulant layer are always removed sequentially and in opposite directions under the downward pressure constraint, effectively improving the removal rate of the encapsulant layer; furthermore, based on the downward pressure and scraping cooperation of the second workstation, the encapsulant layer of the double-glass module can be removed in one go; thirdly, synchronous lifting and lowering adjustment meets the requirements of removing the encapsulant layer under the same scraping working condition. First, the first and second adhesive film removal areas are scraped to ensure uniform removal of the adhesive film. Fourth, during scraping, the module is pressed down through each scraping channel by the pressing group, and the brushing group simultaneously presses down on the module and is used to sweep away the formed adhesive film fragments, ensuring that the adhesive film fragments are swept away from the module surface in time to avoid residue. Fifth, it is ensured that the adhesive film fragments on the surface of the module are cleaned during the forward and reverse movement of the module in the third station to avoid residues that may affect the scraping of the tool. Sixth, it can be adaptively flattened and straightened according to the changes in the flatness of the double-glass module surface to avoid excessive pressure that may cause damage to the bottom glass layer. Seventh, it avoids large areas of adhesive film fragments remaining on the transfer rollers, which may affect the subsequent transfer of modules.
