Description
Technical Field
The invention relates to the technical field of solar cells, in particular to a high-temperature cloth cleaning device and a high-temperature cloth cleaning method.
Background
The solar photovoltaic module encapsulates glass, a photovoltaic cell packaging adhesive film, a cell piece, a back plate and the like in a laminating mode, and in the process, the photovoltaic cell packaging adhesive film inevitably generates hot melting overflow in the laminating process and inevitably has pollution particles in the internal environment of laminating equipment, so that the high-temperature cloth of the laminating equipment is attached with the combination of the overflow adhesive film and the pollution particles, which are collectively called as residual adhesive, and the quality of the photovoltaic module is influenced.
With the continuous development of new energy photovoltaic technology, the continuous expansion of new energy photovoltaic industry productivity and the improvement of appearance requirements of customers on photovoltaic products, in order to meet the requirements of customers, each component manufacturer needs to ensure that no adhesive residue exists on high-temperature cloth in the packaging and laminating process of a photovoltaic component so as to prevent the adhesive residue from being bonded on the photovoltaic component to influence the photovoltaic component. Based on this, it is necessary to periodically clean the high-temperature cloth which the laminating apparatus has.
In order to remove the residual glue attached to the high-temperature cloth, the high-temperature cloth is detached from the laminating equipment in the prior art, and the residual glue and the pollution particles attached to the high-temperature cloth are cleaned up by using tools such as a blade and the like manually and then are installed on the laminating equipment again for use. The method is long in time consumption, and can be completed only by increasing cleaning manpower and cooperation of laminating equipment operators, so that the capacity of the photovoltaic module is seriously influenced, and the labor cost is increased. Meanwhile, the blade is used for assisting in the manual cleaning process to clean the combination of the residual adhesive and the pollution particles attached to the high-temperature cloth, so that the blade is easy to scratch the high-temperature cloth in the cleaning process, and potential safety hazards exist.
Disclosure of Invention
The invention aims to provide a high-temperature cloth cleaning device and a high-temperature cloth cleaning method, which are used for cleaning high-temperature cloth without disassembling the high-temperature cloth, improving the manufacturing efficiency of a photovoltaic module and reducing the risk of scratching the high-temperature cloth.
In a first aspect, the invention provides a high-temperature cloth cleaning device, which is used for cleaning residual glue on high-temperature cloth in laminating equipment. This high temperature cloth cleaning device includes: heat-resisting centre gripping frock and install the laminated structure on heat-resisting centre gripping frock. The laminated structure is provided with at least one bare rubber layer and at least one supporting layer, wherein the at least one bare rubber layer is arranged on the at least one supporting layer, and when cleaning is performed, the at least one bare rubber layer is in contact with the high-temperature cloth and is crosslinked with residual rubber.
In the high-temperature cloth cleaning device provided by the invention, the laminated structure is provided with at least one bare rubber layer used for being in contact with the high-temperature cloth and at least one supporting layer, the at least one bare rubber layer is arranged on the at least one supporting layer, and the at least one bare rubber layer is in contact with the high-temperature cloth and is crosslinked with residual rubber on the high-temperature cloth. Because the surface of the existing high-temperature cloth is provided with the Teflon coating, the hydrophilicity of the coating is good, and therefore, the cohesiveness of the residual glue and the high-temperature cloth is smaller than that of the residual glue and the bare glue layer. Based on this, when the at least one bare rubber layer contacts with the high-temperature cloth and is subjected to high-temperature lamination, the residual rubber and the at least one bare rubber layer are melted and are bonded together through a cross-linking reaction, and at this time, the residual rubber can be removed from the high-temperature cloth only by removing the laminated structure installed on the heat-resistant clamping tool from between the high-temperature cloth. Meanwhile, the laminated structure is arranged on the heat-resistant clamping tool, after high-temperature lamination, the laminated structure and the heat-resistant clamping tool are bonded together by the molten bare rubber layer, the heat-resistant performance of the heat-resistant clamping tool is good, and the bonding force between the heat-resistant clamping tool and the residual rubber on the high-temperature cloth is weak, so that the laminated structure can be smoothly taken out of the laminating equipment through the heat-resistant clamping tool, and the situation that the laminated structure is easily rolled into the laminating equipment by the high-temperature cloth when the bonding force between the residual rubber and the high-temperature cloth is large due to the overlarge area of the residual rubber is prevented.
In summary, the high-temperature cloth cleaning device provided by the invention utilizes the relationship that the adhesive force between the bare rubber layer and the residual rubber on the high-temperature cloth is larger than the adhesive force between the high-temperature cloth and the residual rubber, the bare rubber layer and the residual rubber on the high-temperature cloth are bonded together through a cross-linking reaction, so that the residual rubber on the high-temperature cloth is removed, and the laminated structure is clamped by the heat-resistant clamping tool, so that the risk that the laminated structure bonded with the residual rubber is rolled into the laminating equipment along with the high-temperature cloth is avoided, and the cleaning efficiency of the high-temperature cloth and the productivity of the photovoltaic module are improved.
In a possible implementation manner, the number of the bare rubber layers is two, and the two bare rubber layers are oppositely arranged on two sides of the at least one supporting layer. Through setting up two naked glue films of relative setting on the both sides of at least one supporting layer, can get rid of the incomplete glue on the high temperature cloth of upper and lower two sides in the lamination equipment simultaneously, further improve the clean efficiency of high temperature cloth.
In a possible implementation manner, each support layer is a heat-resistant support layer, the heat-resistant temperature of the heat-resistant support layer is 120-150 ℃, and the heat-resistant temperature of the heat-resistant clamping tool is 100-180 ℃. By using the heat-resistant support layer with the heat-resistant temperature of 120-150 ℃, the heat-resistant support layer can hardly deform and still support at least one bare rubber layer during high-temperature lamination. And because the high-temperature cloth is provided with the Teflon coating, compared with the adhesive force between the high-temperature cloth and the at least one bare rubber layer, the adhesive force between the heat-resistant supporting layer and the at least one bare rubber layer is stronger, so that the influence of part of the at least one bare rubber layer on the high-temperature cloth to the cleaning efficiency of the high-temperature cloth can be prevented.
In one possible implementation, each of the support layers includes one or more of an aluminum plate, a steel plate, a polyvinylidene fluoride plate, a polyethylene terephthalate plate, and a polybutylene terephthalate plate. The high-temperature-resistant material is selected as the supporting layer, so that the supporting layer can be prevented from deforming in the high-temperature laminating process, and the supporting layer can have a good supporting effect.
In a possible implementation, each of the above-mentioned support layers further comprises at least one adhesive layer, and each bare rubber layer is adhered to the support layer through the corresponding adhesive layer. Wherein each bonding layer is one or two of polyethylene terephthalate film and polypropylene film. Because this supporting layer still includes at least one tie coat, when high temperature lamination, take place cross-linking reaction between this at least one tie coat and the corresponding naked glue film for this supporting layer and corresponding naked glue film can bond together completely, can understand, the area that cull and naked glue film bond is less than the area that supporting layer and naked glue film bond, consequently, can guarantee naked glue film and cull through setting up the tie coat and bond when together, naked glue film can not drop from the supporting layer, thereby guarantee that the cull can be followed high temperature cloth and got rid of.
In one possible implementation, the composition of the residual glue is the same as the composition of the bare glue layer. Because the cohesive force between the same components is higher, therefore, when high temperature lamination, because the component of this naked glue film is the same with the component of cull for this cull can be in the same place with the better bonding of corresponding every naked glue film, thereby promote the cull effect of getting rid of on the high temperature cloth.
In one possible implementation, the above-mentioned components of the residual glue and of each bare glue layer are ethylene-vinyl acetate copolymers or polyolefin elastomers.
In a possible implementation manner, the heat-resistant clamping tool comprises two clamping pieces, the side edges of the two clamping pieces are hinged together, and the laminated structure is located between the two clamping pieces. By placing the laminated structure between the two clamping members, the laminated structure can enter between the two high temperature cloths under the clamping of the two clamping members. When high temperature lamination, the laminated structure arranged between the two clamping pieces is melted and then bonded with the heat-resistant clamping tool, at the moment, the heat-resistant clamping tool has good heat resistance, deformation cannot occur in the high temperature lamination process, the heat-resistant clamping tool does not have bonding property, and the bonding force between the heat-resistant clamping tool and the adhesive residue is poor, so that the laminated structure can be taken out of the laminating equipment through the heat-resistant clamping tool, and the situation that the laminated structure and the high temperature cloth are bonded together and are difficult to remove from the high temperature cloth due to overlarge area of the adhesive residue is prevented.
In one possible implementation, each of the clips includes a clip body, at least one extension connected to the clip body, and at least one handle connected to the clip body. The laminated structure is located between the two clamp bodies. Through setting up the extension that holder body and holder body coupling for laminated structure can be better fix on heat-resisting centre gripping frock, and through setting up the handle, can be more convenient take out laminated structure after the high temperature lamination from lamination equipment.
In a possible implementation manner, the clamping piece body and the at least one extending portion form a window, the window is an open window or a closed window, and the laminated structure is arranged between the windows in a clamping manner and exposes at least part of the bare rubber layer. Because the heat-resistant clamping tool is provided with the window which exposes at least part of the bare rubber layer, at least part of the bare rubber layer can be in contact with residual rubber and then is crosslinked and bonded together.
In a second aspect, the invention also provides a cleaning method of the high-temperature cloth, which is used for cleaning residual glue on the high-temperature cloth in the laminating equipment. The laminating apparatus has a laminating space. The cleaning method of the high-temperature cloth comprises the following steps:
step 100: there is provided a high temperature cloth cleaning apparatus as described in the first aspect or any one of the first aspects. The high-temperature cloth cleaning device comprises a heat-resistant clamping tool and a laminated structure arranged on the heat-resistant clamping tool.

Fig. 1 illustrates a first structural schematic diagram of a use state of a high-temperature cloth cleaning apparatus provided in an embodiment of the present invention, and fig. 2 illustrates a second structural schematic diagram of a use state of a high-temperature cloth cleaning apparatus provided in an embodiment of the present invention. As shown in fig. 1 and 2, the high temperature cloth cleaning apparatus includes: heat-resisting centre gripping frock 1 and install stacked structure 2 on heat-resisting centre gripping frock 1. The laminated structure 2 has at least one bare rubber layer 21 and at least one support layer 22. The at least one bare rubber layer 21 is disposed on the at least one support layer 22, and when cleaning is performed, the at least one bare rubber layer 21 is in contact with the high temperature cloth and is cross-linked with the residual rubber.
Therefore, the surface of the existing high-temperature cloth is provided with the Teflon coating, and the hydrophilicity of the coating is good, so that the cohesiveness of the residual glue and the high-temperature cloth is smaller than that of the residual glue and the bare glue layer. Based on this, when the at least one bare rubber layer contacts with the high-temperature cloth and is subjected to high-temperature lamination, the residual rubber and the at least one bare rubber layer are melted and are bonded together through a cross-linking reaction, and at this time, the residual rubber can be removed from the high-temperature cloth only by removing the laminated structure installed on the heat-resistant clamping tool from between the high-temperature cloth. Meanwhile, the laminated structure is arranged on the heat-resistant clamping tool, after high-temperature lamination, the laminated structure and the heat-resistant clamping tool are bonded together by the molten bare rubber layer, the heat-resistant clamping tool is good in heat resistance, and the bonding force between the heat-resistant clamping tool and the residual rubber on the high-temperature cloth is weak, so that the laminated structure can be smoothly taken out of the laminating equipment through the heat-resistant clamping tool, and the situation that the laminated structure is easily rolled into the laminating equipment by the high-temperature cloth when the bonding force between the residual rubber and the high-temperature cloth is large due to the fact that the residual rubber area is too large is prevented.
In conclusion, the high-temperature cloth cleaning device provided by the invention utilizes the relation that the adhesive force between the bare rubber layer and the residual rubber on the high-temperature cloth is greater than the adhesive force between the high-temperature cloth and the residual rubber, the bare rubber layer and the residual rubber on the high-temperature cloth are bonded together through a cross-linking reaction, so that the residual rubber on the high-temperature cloth is removed, and the heat-resistant clamping tool is used for clamping the laminated structure, so that the risk that the laminated structure bonded with the residual rubber is rolled into laminating equipment along with the high-temperature cloth is avoided, and the cleaning efficiency of the high-temperature cloth and the productivity of a photovoltaic module are improved.
As shown in fig. 1 and fig. 2, the number of the bare rubber layers 21 may be selected according to actual conditions due to different areas of residual rubber on the high-temperature cloth in actual production, for example, the number of the bare rubber layers may be one, or may be two. When the number of the bare rubber layers 21 is two, two bare rubber layers 21 are oppositely disposed on both sides of at least one support layer 22.
For example, when the laminating apparatus has only one high temperature cloth with residual adhesive, the number of the bare adhesive layers may be one. At this moment, can get rid of the position of the high temperature cloth of cull as required, place this naked glue film on the supporting layer towards this direction of the high temperature cloth with cull for when the high temperature lamination, this naked glue film can contact with the high temperature cloth with cull, with the cull of getting rid of this high temperature cloth with cull, thereby reduce clean cost.
For another example, as shown in fig. 1 and 2, when the high temperature cloths on both the upper and lower surfaces of the laminating apparatus have residual glue, the number of the bare glue layers 21 may be two, and the two bare glue layers 21 are oppositely disposed on both sides of at least one support layer 22. By arranging two bare rubber layers 21 oppositely arranged on two sides of at least one supporting layer 22, residual rubber on high-temperature cloth on the upper surface and the lower surface in the laminating equipment can be removed simultaneously, and the cleaning efficiency of the high-temperature cloth is further improved.
As shown in fig. 1 and 2, the composition of the residual adhesive is the same as that of the bare adhesive layer. Specifically, the components of the residual adhesive and the components of each bare adhesive layer 21 are ethylene-vinyl acetate copolymer or polyolefin elastomer. Because the bonding force after cross-linking occurs between the same components is stronger, when high-temperature lamination is performed, because the components of the bare rubber layer 21 are the same as the components of the residual rubber, the residual rubber can be better bonded with each corresponding bare rubber layer 21, and the residual rubber removing effect on the high-temperature cloth is improved.
As shown in fig. 1 and 2, each of the support layers 22 may be a heat-resistant support layer, and in this case, the heat-resistant support layer has a heat-resistant temperature of 120 to 150 ℃. By using the heat-resistant supporting layer with the heat-resistant temperature of 120-150 ℃, the heat-resistant supporting layer hardly deforms during high-temperature lamination, and can support the at least one bare rubber layer 21, so that the at least one bare rubber layer 21 is prevented from being dispersed and bonded on the high-temperature cloth under the supporting action of the heat-resistant supporting layer after being heated and melted, and the cleaning efficiency of the high-temperature cloth is improved. And because the high-temperature cloth is provided with the Teflon coating which has hydrophilicity, compared with the adhesive force between the high-temperature cloth and the at least one bare rubber layer 21, the adhesive force between the heat-resistant supporting layer and the at least one bare rubber layer 21 is stronger, so that the cleaning efficiency of the high-temperature cloth can be prevented from being influenced by the fact that part of the at least one bare rubber layer 21 is adhered to the high-temperature cloth.
As shown in fig. 1 and 2, in order to realize the supporting function of each support layer 22, each of the support layers 22 may be one or more of an aluminum plate, a steel plate, a polyvinylidene fluoride plate, a polyethylene terephthalate plate, and a polybutylene terephthalate plate. It should be understood that the support layer 22 may have one layer or may have multiple layers. For example, when the support layer 22 is a layer, the support layer 22 may be an aluminum plate, a steel plate, a polyvinylidene fluoride plate, a polyethylene terephthalate plate. When the support layer 22 is multi-layered, the multi-layered support layer 22 may provide a better supporting effect. In this case, the multilayer support layer 22 may have a multilayer structure of an aluminum plate and a steel plate, a steel plate and a polyvinylidene fluoride plate, or may have a multilayer structure of a polyvinylidene fluoride plate, a polyethylene terephthalate plate, a polybutylene terephthalate plate, or the like. By selecting a high temperature resistant hard material as the supporting layer 22, the supporting layer 22 can be prevented from deforming during a high temperature lamination process, so as to ensure that the supporting layer 22 has a good supporting effect.
As shown in fig. 1 and 2, in order to further improve the adhesion between the bare rubber layer 21 and the support layer 22, each of the support layers 22 further includes at least one adhesive layer (not shown), and each of the bare rubber layers 21 is adhered to the support layer 22 by the corresponding adhesive layer. Wherein, the bonding layer can be one or two of polyethylene terephthalate film and polypropylene film. Because the supporting layer 22 further comprises at least one bonding layer, when high-temperature lamination is carried out, a cross-linking reaction can occur between the at least one bonding layer and the corresponding bare rubber layer 21, so that the supporting layer 22 and the corresponding bare rubber layer 21 can be completely bonded together, and it can be understood that the bonding area of the residual rubber and the bare rubber layer 21 is smaller than the bonding area of the supporting layer 22 and the bare rubber layer 21, therefore, the bonding layer can ensure that the bare rubber layer and the residual rubber are bonded together, the bare rubber layer cannot fall off from the supporting layer, and the residual rubber can be removed from the high-temperature cloth.
Fig. 3 illustrates a first structural schematic diagram of a heat-resistant clamping tool of a high-temperature cloth cleaning device according to an embodiment of the present invention. As shown in fig. 1 to 3, the heat-resistant clamping tool 1 includes two clamping members 11, the side edges of the two clamping members 11 are hinged together, and the laminated structure 2 is located between the two clamping members 11. By placing the laminated structure 2 between the two clamping members 11, the laminated structure 2 can be brought between the two high temperature cloths of the laminating apparatus under the clamping of the two clamping members 11. When laminating at high temperature, the laminated structure 2 arranged between the two clamping pieces 11 is melted and then is bonded with the heat-resistant clamping tool 1, at the moment, because the heat-resistant clamping tool 1 has good heat resistance, deformation can not occur in the high-temperature laminating process, and the heat-resistant clamping tool 1 has no cohesiveness and has poor cohesive force with adhesive residue, the laminated structure 2 can be taken out of the laminating equipment through the heat-resistant clamping tool 1, and the situation that the laminated structure 2 and the high-temperature cloth are bonded together and are difficult to remove from the high-temperature cloth due to overlarge area of the adhesive residue is prevented.
As shown in fig. 1 to 3, the heat-resistant temperature of the heat-resistant clamping tool may be 100 to 180 ℃. The material of the heat-resistant clamping tool can be selected according to actual conditions. For example, the heat-resistant clamping tool may be an epoxy resin plate, an aluminum plate, a steel plate, or high-temperature-resistant glass, but is not limited thereto.
As shown in fig. 1 to 3, each of the holders 11 includes a holder body 111, at least one extension 112, and at least one handle 113. The laminated structure 2 is located between two holder bodies 111, at least one extension 112 is located on the laminated structure 2, and at least one extension 112 is connected to the holder bodies 111. At least one handle 113 is connected to the holder body 111. Through setting up holder body 111 and the extension 112 of being connected with holder body 111 for laminated structure 2 can be better fixed on heat-resisting centre gripping frock 1, and through setting up handle 113, can be more convenient take out laminated structure 2 after the high temperature lamination from the lamination equipment.
Fig. 4 illustrates a second structural schematic diagram of the heat-resistant clamping tool of the high-temperature cloth cleaning device provided by the embodiment of the invention, and fig. 5 illustrates a third structural schematic diagram of the heat-resistant clamping tool of the high-temperature cloth cleaning device provided by the embodiment of the invention. As shown in fig. 4 and 5, the number of the extension portions 112 may be one or more. The number of the above-mentioned handles 113 may be one or plural.
For example, as shown in fig. 1 to 3, when the number of the extending portions 112 on each of the grippers 11 is two and the number of the handles 113 is two, the extending portions 112 may be located on both sides of each of the gripper bodies 111, and the handles 113 on each of the grippers 11 are located on both ends of the two gripper bodies 111, so as to facilitate the removal of the laminated structure 2 to which the culls are bonded from the laminating apparatus.
For another example, as shown in fig. 4 and 5, when the number of the extending portions 112 on each of the clamping members 11 is one, and the number of the handles 113 is one, the extending portions 112 may be located in the middle of each of the clamping member bodies 111, and the handles 113 on each of the clamping members 11 may be located on the same side of the two clamping member bodies 111, or of course, may be located on different sides (as shown in fig. 5). In practice, the laminated structure 2 is placed between the two clamps 11 so that the extension 112 is on the laminated structure 2, and it should be noted here that the width of the extension 112 should be as narrow as possible in order to ensure that the contact area of the laminated structure 2 with the adhesive residue is as large as possible. During high-temperature lamination, the bare adhesive layer on the two clamping members 11 melts and is bonded with the clamping members 11. After the high-temperature lamination is completed, the heat-resistant holding jig 1 and the laminated structure 2 bonded to the heat-resistant holding jig 1 are taken out of the laminating apparatus with the aid of a handle. Because the heat-resistant clamping tool 1 is a high-temperature-resistant hard material and the heat-resistant clamping tool 1 has no cohesiveness, the laminated structure 2 bonded with the residual glue on the high-temperature cloth can be conveniently taken out of the laminating equipment through the heat-resistant clamping tool 1.
As shown in fig. 1 to 5, the clamping member body 111 and the at least one extending portion 112 form a window 12, the window 12 is an open window or a closed window, and the laminated structure 2 is disposed between the windows 12 in a clamping manner and exposes at least a portion of the bare rubber layer 21. Because the heat-resistant clamping tool is provided with the window which exposes at least part of the bare rubber layer 21, at least part of the bare rubber layer 21 can be in contact with residual rubber and then is crosslinked and bonded together. It should be noted that, in order to further improve the residual glue removal efficiency, the area of the laminated structure 2 should be as large as possible, and similarly, the length of the clamp body 111 of the heat-resistant clamping tool 1 should be as long as possible.

The high-temperature cloth cleaning device is placed on a feeding platform A of laminating equipment, after high-temperature lamination is carried out in a laminating space B of the laminating equipment, the laminated structure 2 is bonded with the residual glue and the heat-resistant clamping tool 1 to form a combined body W.
