Description

Technical Field

[0001] The present application relates to the technical field of solar cells, and in particular to a film removal device. Background Art

[0002] Solar cells can convert sunlight into electrical energy, and their applications are becoming more and more widespread. In the production process of solar cells, a mask is generally used to prepare some functional layers on the surface of the solar cell. The hollow pattern of the mask is the same as the functional layer pattern. After the mask is covered on the surface of the solar cell, the functional layer material is attached to the hollow pattern of the mask by deposition, printing, evaporation and other methods. The mask is then removed, and the functional layer material in the hollow pattern remains on the surface of the solar cell to form a functional layer.

[0003] Since the strength of the mask plate is reduced after the functional layer is prepared, the mask plate often breaks during the process of removing the mask plate from the surface of the solar cell, resulting in the mask plate being unable to be completely removed. Utility Model Content

[0004] The purpose of the present application is to provide a mask removal device to make the adhesion between the tape and the mask plate stronger and more firm, so as to facilitate the complete removal of the mask plate.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A film removal device, comprising:

[0007] A carrying platform, the carrying platform comprises a first adsorption channel, and the adsorption port of the first adsorption channel is located on the carrying surface of the carrying platform;

[0008] The fitting piece includes a second adsorption channel, and the adsorption port of the second adsorption channel is located on the fitting surface of the fitting piece; or, the fitting piece can apply pressure toward the bearing surface;

[0009] A driving assembly, which can drive the carrying platform and / or the laminating member to move;

[0010] A tape conveying assembly, used for conveying the tape;

[0011] The adhesive tape clamping assembly is used to clamp the flattened adhesive tape and drive the adhesive tape to move.

[0012] When using the film removal device provided in the present application, first place the adhesive body on the carrying surface of the carrying platform, the solar cell sheet of the adhesive body is in contact with the carrying surface, the mask of the adhesive body is located on the side of the solar cell sheet away from the carrying platform, and the adhesive body is adsorbed by the first adsorption channel. After the tape conveying component transfers the tape to the preset position, the tape clamping component clamps the tape and drives the tape to move above the adhesive body, and then drives the tape downward to make the tape and the mask sheet face away from the solar cell sheet. The adhesive body with the tape is as follows Figure 5 As shown. Then, the driving component is used to drive the carrier and / or the bonding member to move, so that the carrier or the bonding member is close to each other, so that the bonding surface is opposite to the carrier surface, and then the first adsorption channel is closed, and the second adsorption channel is opened, so that the adhesive body with the tape is separated from the carrier surface and adhered to the bonding surface. The second adsorption channel acts to press the tape against the adhesive body for a certain period of time, i.e., 0.1s to 300s, so that the bonding force between the tape and the mask is greater, and the two are more firmly bonded. Then, the second adsorption channel is closed and the first adsorption channel is opened, so that the adhesive body with the tape falls back onto the carrier surface. Alternatively, the driving component is used to drive the carrier and / or the bonding member to move, so that the carrier and the bonding member are close to each other, so that the bonding member applies pressure toward the carrier surface, that is, the bonding member presses the tape, thereby making the bonding force between the tape and the mask greater, and the two are more firmly bonded. Finally, the tape is clamped by the tape clamping assembly and driven to move away from the supporting platform so that the tape moves together with the mask, while the solar cell remains in position under the action of the first adsorption channel, and finally the tape drives the mask to separate from the solar cell.

[0013] From the above, it can be seen that in the process of removing the mask plate using the film removal equipment provided by the present application, the adhesive body with the tape will be adsorbed to the bonding surface so that the adhesive body presses the tape, or the bonding part applies pressure to the bearing surface so that the tape presses the adhesive body, both of which can make the bonding force between the tape and the mask plate greater and the bonding more firm. In the process of the tape driving the mask plate to separate from the solar cell, it is not easy for the tape and the mask plate to separate, thereby preventing the mask plate from breaking due to stress concentration during the film removal process, thereby ensuring that the mask plate can be completely removed.

[0014] In one implementation, the carrier and / or the laminating member further comprises a heating component; the heating component comprises a resistance heater, an infrared heater and / or a thermal oil heater, and the heating component is used to heat the hot melt adhesive and the adhesive body, and the hot melt adhesive is heated and melted, and the adhesive force with the mask plate is increased. In addition, in the process of heating the adhesive body by the heating component, the adhesive layer between the mask plate and the solar cell can be heated, thereby reducing the viscosity of the adhesive layer between the mask plate and the solar cell, which is more conducive to the subsequent separation of the mask plate from the solar cell; and / or,

[0015] The carrier also includes a cooling component so that after the adhesive body with the tape falls back onto the carrier, the temperature of the hot melt adhesive can be quickly reduced to a suitable temperature range to ensure a strong adhesion between the hot melt adhesive and the mask plate, which is beneficial for subsequent film removal.

[0016] In one implementation, the carrying surface includes at least one first area, each of which is used to carry an adhesive body; the laminating surface includes at least one second area, the second area is used to adsorb the adhesive body, and the second area is arranged in a one-to-one correspondence with the first area; when the laminating surface is opposite to the carrying surface, the first area and the second area are located opposite to each other, so that after the first adsorption channel is closed and the second adsorption channel is opened, the adhesive body in the first area can be adsorbed into the corresponding second area;

[0017] The bonded body includes a solar cell and a mask.

[0018] In one implementation, the gap between adjacent first regions is 0.1 mm to 500 mm; and / or, the gap between adjacent second regions is 0.1 mm to 500 mm; in this way, the gap between adjacent adhesive bodies on the bearing surface or the bonding surface is kept within a reasonable range, preventing the gap between adjacent adhesive bodies from being too small and causing misalignment and overlap, and at the same time, the bearing surface or the bonding surface can carry or adsorb as many adhesive bodies as possible, thereby improving production efficiency;

[0019] And / or, there are multiple first regions, and the multiple first regions are arranged in multiple rows and columns, a single row or a single column; and / or, there are multiple second regions, and the multiple second regions are arranged in multiple rows and columns, a single row or a single column; in this way, one adhesive tape can be bonded to the masks of multiple adhesive bodies in the same row or column at the same time, and the adhesive tape clamping component can drive a longer adhesive tape to move above the multiple adhesive bodies, and then the adhesive tape clamping component drives the adhesive tape to move downward to bond with the masks of the multiple adhesive bodies, which simplifies the operation and further improves the production efficiency compared with bonding one adhesive tape to the mask of one adhesive body;

[0020] And / or, there is at least one group of adsorption ports on the carrying surface, and there is a group of adsorption ports in each first area; and / or, there is at least one group of adsorption ports on the bonding surface, and there is a group of adsorption ports in each second area; a group of adsorption ports is arranged in each first area or second area, and after the adhesive is located in the first area or the second area, it can completely cover a group of adsorption ports in the area, which is more conducive to the carrying platform to adsorb and fix the adhesive and the bonding part to adsorb the adhesive.

[0021] And / or, the driving component can drive the supporting platform and / or the bonding component to move until the distance between the supporting surface and the bonding surface is no more than 10 mm, so as to prevent position displacement when the bonding component adsorbs the adhesive body, and ensure that the adhesive body in the first area can be accurately adsorbed into the corresponding second area.

[0022] In one implementation, a first boss is further provided in the second region of the laminating surface, and after the laminating surface absorbs the adhesive body, the first boss corresponds to the gap between the adhesive tape;

[0023] The height of the first boss beyond the bonding surface is 1 μm to 80 μm; and / or, the height of the first boss beyond the bonding surface is ±2 μm of the tape thickness; and / or, the length of the first boss is not less than 91 mm. After the bonding surface adsorbs the adhesive, the gap between the first boss and the tape corresponds, so that the first boss has a supporting effect, and the adhesive and the first boss are against each other to prevent the solar cell from being dented and deformed.

[0024] In one implementation, a second boss is further provided in the second region of the bonding surface. After the bonding surface absorbs the adhesive, the second boss corresponds to the gap between the solar cell sheet, so as to further improve the bonding force between the tape 11 and the edge of the mask.

[0025] At least one second protrusion corresponds to the gap between two adjacent solar cells; and / or,

[0026] The height of the second boss exceeding the bonding surface is less than or equal to 100 mm so as not to affect the distance between the bearing surface and the bonding surface after they are close to each other; and / or,

[0027] The length of the second boss is not less than 80 mm to ensure that the edge of the mask plate is more firmly bonded to the tape 11 .

[0028] In one implementation, after the bonding surface absorbs the adhesive body with the tape attached, the absorption port of the bonding surface is staggered with the tape to ensure that the absorption port of the second absorption channel can absorb the adhesive body after the bonding surface forms a negative pressure, thereby making the mask of the adhesive body press the tape, thereby improving the bonding force between the mask and the tape; or,

[0029] A part of the adsorption ports of the bonding surface is staggered with the adhesive tape, and another part of the adsorption ports is blocked by the adhesive tape. In this way, the adsorption ports of a part of the second adsorption channels adsorb the adhesive tape after forming negative pressure on the bonding surface, ensuring that the adhesive tape and the adhesive body are adsorbed on the bonding surface as a whole stably and firmly, and the adsorption ports of the remaining part of the second adsorption channels adsorb the adhesive body after forming negative pressure on the bonding surface, ensuring that the mask of the adhesive body presses the adhesive tape under the action of adsorption, thereby improving the bonding force between the mask and the tape; or,

[0030] The solar cell sheet covers all the adsorption openings of the bonding surface to ensure that the adsorption openings are completely covered by the adhesive body and the tape, further ensuring that the tape and the adhesive body are stably and firmly adsorbed on the bonding surface as a whole to prevent air leakage at the adsorption openings; or,

[0031] The adsorption opening in the second area includes a strip hole. After the bonding member adsorbs the adhesive body, the extension direction of the strip hole intersects with the extension direction of the main grid and the fine grid of the solar cell or the extension direction of the strip hole is perpendicular to the extension direction of the fine grid of the solar cell. In this way, the mask wire at the narrow width position on the mask plate can be prevented from being adsorbed into the strip hole, resulting in poor adhesion between the mask plate and the tape.

[0032] In one implementation, after the adhesive tape is bonded to the adhesive body, the extension direction of the tape is parallel to the extension direction of the main grid of the solar cell, and the tape is located between adjacent main grids; in this way, the tape can be bonded to all mask wires between adjacent main grids, so that during the film removal process, the tape drives all mask wires between adjacent main grids to detach from the solar cell, further preventing the mask wires from breaking, and ensuring that all mask plates are completely removed.

[0033] And / or, the adhesive body is bonded to multiple parallel tapes, each tape is bonded to a mask plate or each tape is bonded to multiple mask plates arranged in sequence, and the number of mask plates bonded to each tape can be set according to actual conditions; and / or, the end of the tape exceeds the edge of the solar cell, which is conducive to the clamping of the tape end.

[0034] In one implementation, the adsorption openings on the bearing surface and / or the fitting surface include strip openings, circular openings, elliptical openings and / or regular polygonal openings, and the adsorption openings have regular shapes for easy processing and manufacturing.

[0035] And / or, the bearing surface of the bearing platform and / or the bonding surface of the bonding piece are both coated with a flexible layer, so as to utilize the buffering effect of the flexible layer to prevent the bonded body from being damaged due to impact force when being adsorbed.

[0036] In one implementation, the film removal device includes two supporting platforms and a laminating member, and the driving assembly drives the laminating member to swing so that the laminating member can be opposite to any supporting platform, and the laminating member is used alternately with the two supporting platforms, thereby further improving the working efficiency; or,

[0069] See also Figure 1 The film removal device provided in the embodiment of the present application is mainly used to remove the mask plate adhered to the solar cell. The film removal device includes a carrier 1, a laminating member 2, a driving component, a tape conveying component, and a tape clamping component. Among them, the bearing surface of the carrier 1 is used to support the adhesive 9. In the use state, the upper surface of the carrier 1 is the bearing surface, and the adhesive 9 can be placed on the bearing surface. Figure 5 As shown, the adhesive body 9 includes a solar cell and a mask, wherein the mask is a polymer mask with viscosity, and the mask and the solar cell are stacked and bonded together. The carrier 1 includes a first adsorption channel, and the adsorption port 10 of the first adsorption channel is located on the carrier surface of the carrier 1, that is, the adsorption port 10 of the first adsorption channel forms a negative pressure on the surface of the carrier surface, so that the adhesive body 9 can be adsorbed on the surface of the carrier surface to achieve fixation of the adhesive body 9.

[0070] The bonding member 2 may include a second adsorption channel, and the adsorption port 10 of the second adsorption channel is located at the bonding surface of the bonding member 2. During use, the lower surface of the bonding member 2 is the bonding surface, and the adsorption port 10 of the second adsorption channel forms a negative pressure on the surface of the bonding surface to adsorb the adhesive 9 on the bonding surface. Alternatively, the bonding member 2 can apply pressure toward the bearing surface, that is, after the adhesive 9 on the bearing surface is affixed with the tape 11, the bonding member 2 can apply pressure toward the adhesive 9 affixed with the tape 11 on the bearing surface. The driving component can drive the carrier 1 and / or the bonding member 2 to move, that is, the driving component can drive the carrier 1 to move or drive the bonding member 2 to move or drive the carrier 1 and the bonding member 2 to move simultaneously, so that the bonding member 2 and the carrier 1 are close to or away from each other. The second adsorption channel and the first adsorption channel can be connected to a vacuum pump to ensure that the adsorption ports 10 of the second adsorption channel and the first adsorption channel form a negative pressure.

[0071] The tape conveying assembly is used to convey the tape 11, that is, the tape 11 can be conveyed along the tape conveying assembly. The tape clamping assembly is used to clamp and flatten the tape 11 and drive the tape 11 to move. After the tape conveying assembly conveys the tape 11 to a suitable position, the tape clamping assembly clamps the tape 11 and flattens the tape 11, and then drives the tape 11 to move above the adhesive body 9, and then the tape 11 is attached to the mask of the adhesive body 9.

[0072] When using the film removal device provided by this application, if Figure 2 As shown, firstly, the adhesive body 9 is placed on the carrying surface of the carrying platform 1, the solar cell of the adhesive body 9 is in contact with the carrying surface, and the mask of the adhesive body 9 is located on the side of the solar cell away from the carrying platform 1, and the adhesive body 9 is adsorbed by the first adsorption channel. After the tape conveying assembly transfers the tape 11 to the preset position, the tape clamping assembly clamps the tape 11 and drives the tape 11 to move above the adhesive body 9, and then drives the tape 11 downward so that the tape 11 is in contact with the surface of the mask away from the solar cell. The adhesive body 9 with the tape 11 is as shown in FIG. Figure 5As shown. Then, the driving component is used to drive the carrier 1 and / or the laminating member 2 to move, so that the carrier 1 or the laminating member 2 is close to each other, so that the laminating surface is opposite to the carrier surface, and then the second adsorption channel is closed, and the second adsorption channel is opened, so that the adhesive body 9 with the tape 11 is separated from the carrier surface and attached to the laminating surface, and the second adsorption channel acts to press the tape 11 tightly for a certain period of time, i.e., 0.1s to 300s, so that the bonding force between the tape 11 and the mask is greater, and the two are more firmly bonded, and then the second adsorption channel is closed and the first adsorption channel is opened, so that the adhesive body 9 with the tape 11 is returned to the carrier surface. Alternatively, the driving component is used to drive the carrier 1 and / or the laminating member 2 to move, so that the carrier 1 or the laminating member 2 is close to each other, so that the laminating member 2 applies pressure toward the carrier surface, that is, the laminating member 2 presses the tape 11, thereby making the bonding force between the tape 11 and the mask greater, and the two are more firmly bonded. Finally, the tape 11 is clamped by the tape clamping assembly, and the tape 11 is driven to move away from the supporting platform 1, so that the tape 11 moves together with the mask, and the position of the solar cell remains unchanged under the action of the first adsorption channel, and finally the tape 11 drives the mask to separate from the solar cell.

[0073] As can be seen from the above, in the process of removing the mask plate using the film removal equipment provided by the present application, the adhesive body 9 with the tape 11 will be adsorbed to the bonding surface so that the adhesive body 9 presses the tape 11, or the bonding part 2 applies pressure to the bearing surface so that the tape 11 presses the adhesive body 9, both of which can make the bonding force between the tape 11 and the mask plate greater and the bonding more firm. In the process of the tape 11 driving the mask plate to separate from the solar cell, it is not easy for the tape 11 to separate from the mask plate, thereby preventing the mask plate from breaking due to stress concentration during the film removal process, thereby ensuring that the mask plate can be completely removed.

[0074] In this application, a robot can be used to take and place the adhesive body 9 or the solar cell from the carrier 1. Specifically, the adhesive body 9 or the solar cell can be taken and placed by a vacuum suction cup, static electricity, adhesion, etc.

[0075] Among them, the adhesive tape 11 can be a self-adhesive adhesive or a hot melt adhesive, and the hot melt adhesive needs to be heated to adhere to the mask. Therefore, the support platform 1 and / or the bonding member 2 can also include a heating component, which is used to heat the hot melt adhesive and the adhesive body 9. After the hot melt adhesive is heated and melted, the adhesion to the mask increases. In addition, in the process of heating the adhesive body 9 by the heating component, the adhesive layer between the mask and the solar cell can be heated, thereby reducing the viscosity of the adhesive layer between the mask and the solar cell, which is more conducive to the subsequent separation of the mask from the solar cell.

[0076] Specifically, only the supporting platform 1 may include a heating component, only the bonding member 2 may include a heating component, or both the supporting platform 1 and the bonding member 2 may include a heating component. This can be set according to actual conditions. For example, when the tape 11 is a self-adhesive tape, only the supporting platform 1 may include a heating component; when the tape 11 is a hot-melt adhesive, both the supporting platform 1 and the bonding member 2 may include a heating component.

[0077] Furthermore, the heating component includes a resistance heater, an infrared heater and / or a thermal oil heater, and any type of heater can be selected for the heating component in the present application. A cavity can be provided inside the carrier 1 or the bonding piece 2, and the heating wire, heating tube, etc. of the heating component can be installed in the cavity, or a hole can be opened on the surface of the carrier 1 or the bonding piece 2, and the heating wire, heating tube, etc. of the heating component can be inserted into the hole.

[0078] In addition, since the hot melt adhesive can only have good adhesion with the mask within a certain temperature range, a cooling component can also be provided in the carrier 1, so that after the adhesive body 9 with the tape 11 falls back onto the carrier 1, the temperature of the hot melt adhesive can be quickly reduced to a suitable temperature range to ensure a strong adhesion between the hot melt adhesive and the mask, which is conducive to subsequent film removal. Specifically, the cooling component can be a cold water circulation component, that is, a cooling water channel is opened inside the carrier 1, or a semiconductor cooling plate.

[0079] The base material of the adhesive tape 11 needs to be able to withstand a certain temperature, and the temperature resistance is not less than 100°C. The thickness of the hot melt adhesive layer is between 3 microns and 50 microns. If the adhesive tape 11 is a self-adhesive layer, the thickness of the self-adhesive layer should be more than 3 microns. The adhesive tape 11 can be in a roll or disc shape, or it can be a sheet material cut into a certain length and width.

[0080] In a specific embodiment, the carrying surface includes at least one first area, and each first area is used to carry one or more adhesive bodies 9, that is, after the adhesive bodies 9 are placed on the carrying surface, the one or more adhesive bodies 9 are located in a first area. The carrying surface may include only one first area, or may include two or more first areas.

[0081] Similarly, the laminating surface includes at least one second area, and the second area is used to adsorb the adhesive 9, that is, after the adhesive 9 is adsorbed on the laminating surface, one or more adhesives 9 are located in a second area. The laminating surface may include only one second area, or the laminating surface may include two or more second areas, in which case the laminating member 2 can adsorb multiple adhesives 9. The second area is arranged in a one-to-one correspondence with the first area, that is, the number of the first area and the second area is the same, and when the laminating surface is opposite to the bearing surface, the first area and the second area are opposite in position, so that after the first adsorption channel is closed and the second adsorption channel is opened, the adhesive 9 in the first area can be adsorbed into the corresponding second area.

[0082] By adopting the above technical solution, the number of the first area and the second area can be set according to the actual situation. When there are multiple first areas and second areas, multiple adhesive bodies 9 can be adsorbed at the same time, thereby improving production efficiency. In addition, the setting of the first area and the second area facilitates the accurate positioning of the tape clamping component, thereby avoiding the position of the adhesive body 9 on the bearing surface and the bonding surface being uncertain, which causes the tape clamping component to need to constantly adjust the positioning position each time it sticks the tape 11.

[0083] In the above embodiment, the gap between adjacent first areas is 0.1 mm to 500 mm. The gap between adjacent second areas is 0.1 mm to 500 mm. The gap between adjacent adhesive bodies 9 on the bearing surface or the bonding surface is kept within a reasonable range to prevent the gap between adjacent adhesive bodies 9 from being too small and causing misalignment and overlap. At the same time, the bearing surface or the bonding surface can carry or adsorb as many adhesive bodies 9 as possible to improve production efficiency.

[0084] Specifically, the gap between adjacent first regions is 0.1 mm, 10 mm, 50 mm, 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm or 500 mm. The gap between adjacent second regions is 0.1 mm, 10 mm, 50 mm, 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm, 450 mm or 500 mm, etc.

[0085] As a preferred embodiment, there are multiple first regions, and the multiple first regions are arranged in multiple rows and columns, a single row or a single column; there are multiple second regions, and the multiple second regions are arranged in multiple rows and columns, a single row or a single column. Figure 7 As shown, in this embodiment, a piece of tape 11 can be bonded to the mask plates of multiple adhesive bodies 9 in the same row or column at the same time, so that the tape clamping assembly can drive a longer piece of tape 11 to move above the multiple adhesive bodies 9, and then the tape clamping assembly drives the tape 11 to move down to bond with the mask plates of multiple adhesive bodies 9. Compared with bonding one piece of tape 11 to the mask plate of one adhesive body 9, the operation is simplified and the production efficiency is further improved.

[0086] In addition, the carrying surface has at least one set of suction ports 10, and each first region has one set of suction ports 10; the bonding surface has at least one set of suction ports 10, and each second region has one set of suction ports 10. In this way, each first region or second region is provided with a set of suction ports 10, and when the adhesive body 9 is located in the first region or the second region, it can completely cover a set of suction ports 10 in the region, which is more conducive to the carrying platform 1 to adsorb and fix the adhesive body 9 and the bonding piece 2 to adsorb the adhesive body 9.

[0087] The driving assembly can drive the carrier 1 and / or the laminating member 2 to move to a point where the distance between the carrier surface and the laminating surface is no greater than 10 mm. When the distance between the carrier surface and the laminating surface is less than or equal to 10 mm, the laminating member 2 can prevent positional displacement when adsorbing the adhesive body 9, thereby ensuring that the adhesive body 9 in the first area can be accurately adsorbed into the corresponding second area. Specifically, the driving assembly can drive the carrier 1 and / or the laminating member 2 to move to a point where the distance between the carrier surface and the laminating surface is 0 mm, 2 mm, 4 mm, 6 mm, 8 mm, or 10 mm.

[0088] Since the adhesive tape 11 has a certain thickness, after the adhesive body 9 with the adhesive tape 11 is adsorbed on the bonding surface, the portion corresponding to the gap between the solar cell and the adhesive tape 11 may be concave and deformed due to the negative pressure. Figure 6 As shown, in view of the above situation, a first boss 2a can also be set in the second area of ​​the bonding surface. After the bonding surface adsorbs the adhesive 9, the gap between the first boss 2a and the tape 11 corresponds. In this way, the first boss 2a plays a supporting role, and the adhesive 9 and the first boss 2a are offset to prevent the solar cell from sinking and deforming.

[0089] In the above embodiment, the height of the first boss 2a beyond the bonding surface is 1 μm to 80 μm, and / or the height of the first boss 2a beyond the bonding surface is ±2 μm of the thickness of the tape 11. The height of the first boss 2a beyond the bonding surface can be set according to the thickness of the tape 11, and preferably the height of the first boss 2a beyond the bonding surface is equal to the thickness of the tape 11. Specifically, the height of the first boss 2a beyond the bonding surface is 1 μm, 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, or 80 μm, etc., preferably 3 μm to 50 μm.

[0090] In addition, the length of the first boss 2a is not less than 91 mm. In this embodiment, the length of the first boss 2a can be set according to the length direction or width direction of the solar cell. If the tape 11 is set along the width direction of the solar cell, the length direction of the first boss 2a is along the length direction of the solar cell. Preferably, the length of the first boss 2a is not less than the length of the solar cell. If the tape 11 is set along the length direction of the solar cell, the length direction of the first boss 2a is along the width direction of the solar cell. Preferably, the length of the first boss 2a is not less than the width of the solar cell. Specifically, the length of the first boss 2a is 91 mm, 100 mm, 110 mm, 120 mm, etc.

[0091] like Fig.14A , 14B, 14C, 15A, 15B and 15C, in another embodiment, a second boss 2b is further provided in the second region of the bonding surface, and after the bonding surface adsorbs the adhesive body 9, the second boss 2b corresponds to the gap between the solar cells. In this way, the area between the second bosses 2b is more likely to form a negative pressure, and the second bosses 2b block the flow of airflow so that the negative pressure in the area around the second bosses 2b remains stable, which can further improve the adhesion between the tape 11 and the edge of the mask. In this embodiment, at least one second boss 2b corresponds to the gap between two adjacent solar cells, specifically, as Fig.14A , 14B As shown in FIG. 14C , only one second protrusion 2b may correspond to the gap between two adjacent solar cells; or Fig.15A , 15B As shown in FIG. 15C , two second bosses 2b correspond to the gap between two adjacent solar cells. When multiple second bosses 2b correspond to the gap between two adjacent solar cells, multiple second bosses 2b can be arranged parallel to each other, and the second bosses 2b can be set according to actual conditions.

[0092] If the height of the second boss 2b beyond the bonding surface is too high, it may affect the distance between the bearing surface and the bonding surface after they are close together. If the height of the second boss 2b beyond the bonding surface is too low, it may not be able to achieve the purpose of blocking the airflow. Therefore, the height of the second boss 2b beyond the bonding surface is less than or equal to 100mm. Specifically, the height of the second boss 2b beyond the bonding surface is 1mm, 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm or 100mm.

[0093] In addition, the length of the second boss 2b is not less than 80mm. The length of the second boss 2b can be set along the length direction of the solar cell, or the length of the second boss 2b can also be set along the width direction of the solar cell, which can be set according to actual conditions. The length of the second boss 2b can be designed with reference to the size of the solar cell, and the length of the second boss 2b can be an integer multiple of the length or width of the solar cell. The length of the second boss 2b is not less than the length or width of the solar cell to ensure that the edge of the mask is more firmly bonded to the tape 11. Specifically, the length of the second boss 2b is 80mm, 100mm, 125mm, 150mm, 175mm, etc.

[0094] In the above embodiment, the bonding surface may be provided with the first boss 2a and the second boss 2b at the same time. Of course, the bonding surface may also be provided with only the first boss 2a or the second boss 2b.

[0095] In a preferred embodiment, after the bonding surface absorbs the adhesive body 9 with the adhesive tape 11 attached, the absorption openings 10 of the bonding surface are staggered with the adhesive tape 11, that is, after the bonding surface absorbs the adhesive body 9 with the adhesive tape 11 attached, the absorption openings 10 of the bonding surface correspond to the gap between the adhesive tape 11, and the adhesive tape 11 does not cover any absorption openings 10. Such an arrangement can ensure that the absorption openings 10 of the second absorption channel can absorb the adhesive body 9 after the bonding surface forms a negative pressure, thereby making the mask of the adhesive body 9 press the adhesive tape 11, and improving the bonding force between the mask and the adhesive tape 11; if all the absorption openings 10 of the bonding surface are blocked by the adhesive tape 11, the adhesive body 9 cannot be absorbed, and the adhesive body 9 cannot be absorbed on the bonding surface.

[0096] Alternatively, after the bonding surface absorbs the adhesive body 9 with the tape 11 attached thereto, a portion of the absorption ports 10 of the bonding surface are staggered with the tape 11, and another portion of the absorption ports 10 are blocked by the tape 11. Specifically, after the bonding surface absorbs the adhesive body 9 with the tape 11 attached thereto, the tape 11 blocks a portion of the absorption ports 10 on the bonding surface, and the tape 11 does not block the remaining absorption ports 10 on the bonding surface. In this way, a portion of the absorption ports 10 of the second absorption channel absorb the tape 11 after negative pressure is formed on the bonding surface, ensuring that the tape 11 and the adhesive body 9 are stably and firmly absorbed on the bonding surface as a whole, and the remaining portion of the absorption ports 10 of the second absorption channel absorb the adhesive body 9 after negative pressure is formed on the bonding surface, ensuring that the mask of the adhesive body 9 presses the tape 11 under the action of absorption, thereby improving the bonding force between the mask and the tape 11.

[0097] In addition, after the bonding surface adsorbs the adhesive body 9 with the tape 11, the solar cell covers all the adsorption ports 10 of the bonding surface. This arrangement can ensure that the adsorption ports 10 are completely covered by the adhesive body 9 and the tape 11, and further ensure that the tape 11 and the adhesive body 9 are stably and firmly adsorbed on the bonding surface as a whole, preventing air leakage at the adsorption ports 10.

[0098] As a preferred embodiment, the adsorption port 10 in the second region includes a strip hole. After the bonding surface of the bonding member 2 adsorbs the adhesive body 9, the extension direction of the strip hole intersects with the extension direction of the solar cell main grid 9a and the fine grid 9b, or the extension direction of the strip hole is perpendicular to the extension direction of the solar cell fine grid 9b. This arrangement can prevent the mask wire at a narrow width position on the mask from being adsorbed into the strip hole, resulting in poor adhesion between the mask and the tape 11. Specifically, the angle between the extension direction of the strip hole and the extension direction of the solar cell fine grid 9b can be 30°, 45°, or 60°.

[0099] like Figure 5As shown, after the adhesive tape 11 is bonded to the adhesive body 9, the extension direction of the adhesive tape 11 is parallel to the extension direction of the main grid 9a of the solar cell, and perpendicular to the extension direction of the fine grid 9b, and the adhesive tape 11 is located between adjacent main grids 9a. Since the width of the mask wire in the hollow area of ​​the mask plate used to form the fine grid 9b is relatively small, the mask wire at the above position is most likely to break during the film removal process, so the extension direction of the adhesive tape 11 is set perpendicular to the extension direction of the fine grid 9b, so that the adhesive tape 11 can be bonded to all the mask wires between the adjacent main grids 9a, so that during the film removal process, the adhesive tape 11 drives all the mask wires between the adjacent main grids 9a to detach from the solar cell, further preventing the mask wire from breaking, and ensuring that all the mask plates are completely removed.

[0100] In addition, the adhesive body 9 can be bonded to a plurality of parallel adhesive tapes 11, each adhesive tape 11 is bonded to a mask plate, or each adhesive tape 11 is bonded to a plurality of mask plates arranged in sequence. Figure 5 As shown, each tape 11 is bonded to a mask plate, or as Figure 7 As shown, each tape 11 is bonded to a plurality of masks arranged in sequence. The number of masks bonded to each tape 11 can be set according to actual conditions. When each tape 11 is bonded to a plurality of masks arranged in sequence, the tape 11 can be cut into multiple sections or a whole strip without being cut in the middle.

[0101] Of course, the adhesive body 9 can also be bonded with a tape 11, but the tape 11 cannot completely cover the mask, otherwise, after the adhesive body 9 is adsorbed on the bonding surface, the bonding force between the tape 11 and the mask cannot be increased.

[0102] If the end of the tape 11 is aligned with the edge of the solar cell, the end of the tape 11 needs to be lifted up first and then clamped by the clamp 7. In view of the above situation, in the present application, the end of the tape 11 exceeds the edge of the solar cell, which is more conducive to the clamp 7 to clamp the end of the tape 11.

[0103] like Figure 3 and Figure 4 As shown, the suction ports 10 on the bearing surface and / or the bonding surface may include strip-shaped openings, circular openings, elliptical openings and / or regular polygonal openings, and the suction ports 10 have regular shapes for easy processing and manufacturing. The suction ports 10 may be of any shape, as long as they can adsorb the adhesive 9. Of course, when the shapes of the suction ports 10 on the bearing surface and / or the bonding surface are the same, the multiple suction ports 10 may be distributed in a display manner, specifically in a rectangular array, an annular array, etc. Of course, the multiple suction ports 10 may also be distributed unevenly. In addition, the shape of each group of suction ports 10 may be the same or different. When the shape of each group of suction ports 10 is the same, they may be evenly distributed in the first area or the second area, or they may be unevenly distributed.

[0104] The carrying platform 1 is a metal platform, a plastic platform or a rubber platform. In addition, the bonding member 2 is a metal plate, a plastic plate or a rubber plate. While ensuring the mechanical strength of the carrying platform 1 and the bonding member 2, the manufacturing cost is reduced as much as possible.

[0105] Since both the bearing surface and the bonding surface need to adsorb the adhesive 9, a flexible layer can be applied to the bearing surface of the bearing platform 1 and / or the bonding surface of the bonding piece 2 to utilize the buffering effect of the flexible layer to prevent the adhesive 9 from being damaged due to impact force when being adsorbed.

[0106] like Figure 8 As shown, the film removal device may include two carriers 1 and a laminating member 2, and both sides of the laminating member 2 are laminating surfaces. The driving component can drive the laminating member 2 to swing so that the laminating member 2 can be opposite to any carrier 1, so that during the loading process of one carrier 1, the laminating member 2 can absorb the adhesive 9 on the other carrier 1, and the laminating member 2 is used alternately with the two carriers 1, further improving the working efficiency. In this embodiment, the driving component may include a motor, and the motor drives the laminating member 2 to swing.

[0107] The driving assembly may also be a telescopic cylinder, which drives the laminating component to move closer to or away from the supporting platform 1 .

[0108] In addition, only the lower surface of the bonding member 2 can be the bonding surface, and the bonding member 2 can press the bearing surface to apply pressure. Specifically, the driving component drives the bonding member 2 to move toward the bearing platform 1, so that the bonding member 2 presses the adhesive body 9 with the tape 11, thereby improving the adhesion between the tape 11 and the mask, which is conducive to the subsequent complete removal of the mask.

[0109] like Fig.12 and 13 As shown, the bonding member may include at least one roller 13, and the roller 13 can roll the bearing surface to apply pressure. Specifically, the driving component drives the roller 13 to roll on the adhesive body 9 with the tape 11 to press the adhesive body 9 with the tape 11, and also improve the bonding force between the tape 11 and the mask.

[0110] When multiple adhesive tapes 11 are bonded to the bonded body 9, as shown in FIG. Fig.13 As shown, a plurality of raised rings may be provided on the roller 13, and the raised rings roll correspondingly on a plurality of adhesive tapes 11 to ensure the pressure of the adhesive tapes 11. Alternatively, as Fig.12 As shown, the surface of the roller 13 may also be a cylindrical surface, which is not limited here.

[0111] like Fig. 9 and Fig.10 As shown, the tape clamping assembly includes at least one clamping jaw 7 and a driving member for driving the clamping jaw 7 to move, and each clamping jaw 7 can clamp the end of at least one tape 11. Fig. 9As shown, the clamping jaws 7 can be arranged in a row, so that multiple clamping jaws 7 in the same row can clamp the ends of multiple tapes 11 at the same time; Fig.10 As shown, only one clamping jaw 7 may be provided, and the clamping jaw 7 may simultaneously clamp the ends of multiple tapes 11. In this embodiment, only one end of the tape 11 may be clamped by the clamping jaw 7, so that the tape is gradually torn off from one side of the mask during the film removal process; or both ends of the tape 11 may be clamped by the clamping jaw 7, so that the tape is gradually torn off from both sides of the mask during the film removal process.

[0112] like Figure 1 As shown, the tape conveying assembly includes a discharge tray 3, a clamping member 6, a cutting member, and at least one guide wheel 4 located between the clamping member 6 and the discharge tray 3. The clamping member 6 can clamp and fix the end of the tape 11, and the cutting member can cut the tape 11. The unwound tape 11 of the discharge tray 3 is conveyed along the guide wheel 4. After the tape 11 is transmitted to the clamping member 6, the clamping member 6 can clamp the tape 11, and then the cutting member cuts the tape 11, so that the tape clamping assembly can clamp the end of the tape 11.

[0113] The clamping member 6 includes a base and a pressing block that can be raised and lowered relative to the base, that is, when the pressing block is raised, the tape 11 can move below the pressing block, and then the pressing block is lowered to press the tape 11. The pressing block and the base can be threadedly connected, or a plug rod is provided on the base, and the pressing block can be inserted into the plug rod.

[0114] At least one tensioning wheel 5 is further provided between the clamping member 6 and the discharge tray 3 , and the adhesive tape 11 can be always kept in a flattened and tensioned state through the adjustment of the tensioning wheel 5 .

[0115] like Fig.11 As shown, the cutting piece includes a knife seat and a cutter 8 fixed to the knife seat, and the blade of the cutter 8 is arranged upward, so that the tape clamping assembly clamps the tape 11 and moves it to the cutting piece position, and the tape 11 is cut by the cutter 8. The cutting piece can be installed on a knife holder 12, and a guide rail can be arranged on the knife holder 12. The knife seat and the guide rail are slidably matched to move the knife seat along the guide rail to a suitable position. In this embodiment, the knife seat can be driven to move along the guide rail by components such as a telescopic cylinder and a linear motor.

[0116] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0117] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
