Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a laminating tool. Background Art

[0002] With the development of the photovoltaic industry, there are more and more large-scale ground power stations, and the excellent land resources for the construction of photovoltaic power stations are becoming increasingly scarce. In addition, with the promotion of green building policies and related standards in recent years, various regions have introduced photovoltaic building integration subsidy policies to promote the construction of rooftop power stations.

[0003] Photovoltaic modules, as key equipment for building rooftop power stations, are also receiving more and more attention. Existing photovoltaic modules on the market are made of laminated modules using a laminating machine. The structure of the laminated module is similar to a "sandwich" structure, namely, front glass + encapsulation film + battery cell + encapsulation film + back glass. The front glass and the back glass are staggered and laminated. In related technologies, a laminating tool is used to fix the laminated modules to be laminated, but the fixing effect of the laminating tool is poor. For example, the laminated module fixed by the laminating tool is prone to large-area bubbles at the staggered position of the front glass and the back glass after being pressed by the laminating machine.

[0019] A second gap is defined between a side of the second frame close to the first support member and a side of the second support surface facing away from the second support member along the first direction.

[0020] In one embodiment, the first gap is between 5 mm and 20 mm in the first direction; and / or the second gap is between 5 mm and 20 mm in the first direction.

[0021] In one embodiment, the laminate frame includes a third frame and a fourth frame;

[0022] The third frame and the fourth frame are arranged in a one-to-one correspondence at intervals on two opposite sides of the support assembly along the third direction, and are both located between the first frame and the second frame;

[0023] One end of the third frame is connected to the first frame, and the other end is connected to the second frame;

[0024] One end of the fourth frame is connected to the first frame, and the other end is connected to the second frame.

[0025] In one embodiment, a distance between a side of the third frame close to the support assembly along the third direction and a side of the support assembly close to the third frame along the third direction is between 0 and 5 mm;

[0026] And / or, a distance between a side of the fourth frame close to the support assembly along the third direction and a side of the support assembly close to the fourth frame along the third direction is between 0 and 5 mm.

[0027] The laminating tooling in this embodiment is configured such that a first support member and a second support member are arranged at intervals along a first direction, and opposite sides of the first support member along the second direction are respectively a first support surface and a second support surface, so that a worker can use the second support surface to support one side of the rear glass in the laminating assembly along the first direction, so that the other side of the rear glass along the first direction is located between the first support member and the second support member, and the battery cell in the laminating assembly is arranged between the first support member and the second support member, so that the battery cell contacts the rear glass along the side close to the second support surface; and a third support surface is configured such that one side of the second support member along the second direction is a third support surface, and the distance between the third support surface and the first support surface is smaller than the distance between the first support surface and the second support surface, and the distance between the third support surface and the second support surface is smaller than the distance between the first support surface and the second support surface, so that a worker can use the third support surface to support one side of the front glass in the laminating assembly along the first direction, and so that the other side of the front glass contacts the side of the battery cell facing away from the rear glass along the first direction, so that the front glass and the rear glass are staggered in the first direction and stacked in the second direction.

[0028] By setting the distance between the third supporting surface and the second supporting surface to be greater than the sum of the sizes of the battery cell and the packaging film in the laminated assembly to be fixed, there is a height difference in the second direction on the opposite sides of the front glass along the first direction, and then a gap is formed between the front glass and the packaging film located on the side of the battery cell close to the front glass, so that the subsequent lamination equipment can squeeze the gap to gradually reduce it when laminating the laminated assembly, and discharge the gas in the laminated assembly through the gap, thereby reducing the risk of a large number of bubbles generated at the misaligned position of the front glass and the rear glass; in summary, compared with the laminated assembly fixed by the traditional lamination tool, the lamination tool in the present application fixes the laminated assembly and then uses a laminator to laminate the laminated assembly. The gas in the laminated assembly will be discharged through the gap between the front glass and the packaging film, and large-area bubbles are not easily generated at the misaligned position of the front glass and the rear glass of the laminated assembly. The fixing effect of the lamination tool is better, and can meet the design requirements of the laminated assembly with misaligned glass plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] See also Figures 1 to 4 , Figure 1The figure shows an assembly diagram of a laminating tool 1000 and a laminated component 2000 to be fixed in an embodiment of the present application. The laminating tool 1000 provided in an embodiment of the present application includes: a support assembly 1100, the support assembly 1100 includes a first support member 1110 and a second support member 1120 spaced apart along a first direction, the first support member 1110 has a first support surface 1111 and a second support surface 1112 on opposite sides along the second direction, the second direction is perpendicular to the first direction, one side of the second support member 1120 along the second direction is a third support surface 1121, and in the second direction, the third support surface 1121 is aligned with the first support surface 1111. The distance D1 between the support surfaces 1111 is smaller than the distance D2 between the first support surface 1111 and the second support surface 1112, and the distance D3 between the third support surface 1121 and the second support surface 1112 is smaller than the distance D2 between the first support surface 1111 and the second support surface 1112, and the distance D3 between the third support surface 1121 and the second support surface 1112 is greater than a first value, which is the sum of the dimensions of the battery cell 2300 and the encapsulation film 2200 in the laminate assembly 2000 to be fixed in the second direction.

[0053] The laminated assembly 2000 fixed by traditional laminating tooling lacks an exhaust channel. After the laminator laminates the laminated assembly 2000, the gas in the laminated assembly 2000 cannot be completely discharged, and large-scale bubbles are easily generated at the misalignment between the front glass 2100 and the rear glass 2400 of the laminated assembly 2000.

[0054] The laminating tool 1000 in this embodiment is arranged by arranging the first support member 1110 and the second support member 1120 in a spaced manner along the first direction, and the first support member 1110 has the first support surface 1111 and the second support surface 1112 on opposite sides along the second direction, so that the staff can support the back plate glass 2400 in the laminating assembly 2000 along one side of the first direction with the help of the second support surface 1112, so that the other side of the back plate glass 2400 along the first direction is located between the first support member 1110 and the second support member 1120, and the battery cell 2300 in the laminating assembly 2000 is arranged between the first support member 1110 and the second support member 1120, so that the battery cell 2300 is in contact with the back plate glass 2400 along the side close to the second support surface 1112; by arranging the second support member 1110 and the second support member 1120, One side of the component 1120 along the second direction is the third supporting surface 1121, and the distance D1 between the third supporting surface 1121 and the first supporting surface 1111 is smaller than the distance D2 between the first supporting surface 1111 and the second supporting surface 1112, and the distance D3 between the third supporting surface 1121 and the second supporting surface 1112 is smaller than the distance D2 between the first supporting surface 1111 and the second supporting surface 1112, so that the staff can use the third supporting surface 1121 to support one side of the front glass 2100 in the laminated assembly 2000 along the first direction, and make the front glass 2100 contact with the side of the battery cell 2300 away from the rear glass 2400 along the other side of the first direction, so as to realize the staggered arrangement of the front glass 2100 and the rear glass 2400 in the first direction and the stacked arrangement in the second direction.

[0055] By setting the distance D3 between the third supporting surface 1121 and the second supporting surface 1112 to be greater than the sum of the sizes of the battery cell 2300 and the packaging film 2200 in the laminated assembly 2000 to be fixed, a height difference is formed in the second direction between the two opposite sides of the front glass 2100 along the first direction, thereby forming a gap between the front glass 2100 and the packaging film 2200 located on the side of the battery cell 2300 close to the front glass 2100, so that the subsequent laminating equipment (not shown) can squeeze the gap to gradually reduce it when laminating the laminated assembly 2000, and discharge the gas in the laminated assembly 2000 through the gap, thereby reducing the pressure on the front glass 2100. 0 and the rear glass 2400 at the misaligned position; in summary, compared with the laminated assembly 2000 fixed by the traditional laminating tool, the laminating tool 1000 in the present application fixes the laminated assembly 2000, and when the laminated assembly 2000 is laminated by a laminator, the gas in the laminated assembly 2000 will be discharged through the gap between the front glass 2100 and the packaging film 2200, and it is not easy to generate large-area bubbles at the misaligned position between the front glass 2100 and the rear glass 2400 of the laminated assembly 2000. The fixing effect of the laminating tool 1000 is better, and can meet the design requirements of the laminated assembly 2000 with misaligned glass plates.

[0056] See also Figures 1 to 4 In some embodiments, the difference between the distance D3 between the third supporting surface 1121 and the second supporting surface 1112 and the first value is between 0.5 mm and 1 mm.

[0057] In this embodiment, the difference between the distance D3 between the third supporting surface 1121 and the second supporting surface 1112 and the first value is set to be between 0.5 mm and 1 mm. This allows the operator to place the battery cell 2300 between the first support member 1110 and the second support member 1120, and allow the battery cell 2300 to contact the rear glass 2400 along the side close to the second supporting surface 1112. In the second direction, a height difference of between 0.5 mm and 1 mm is generated between the third supporting surface 1121 and the packaging film 2200 located on the side of the battery cell 2300 away from the rear glass 2400. This facilitates the front glass 2100 to contact the third supporting surface 1121 at one end along the first direction and contact the third supporting surface 1121 at the other end. When the packaging film 2200 on one side of the front glass 2100 contacts the packaging film 2200 on the side of the battery cell 2300, a small gap with a size of 0.5mm to 1mm in the second direction is formed between the front glass 2100 and the packaging film 2200 located on the side of the battery cell 2300 away from the rear glass 2400. On the one hand, it can prevent the height difference between the two opposite sides of the front glass 2100 along the first direction from being too large in the second direction, thereby reducing the risk of the front glass 2100 being crushed when the laminating equipment is laminating the laminated assembly 2000. On the other hand, it is convenient for the subsequent laminating equipment to squeeze the small gap to gradually reduce it when laminating the laminated assembly 2000, and to discharge the gas in the laminated assembly 2000 through the small gap, thereby reducing the risk of a large number of bubbles generated at the misaligned position between the front glass 2100 and the rear glass 2400.

[0058] It should be further explained that the packaging film 2200 includes a front packaging film 2210 and a rear packaging film 2220. The front packaging film 2210 is arranged on the side of the battery cell 2300 along the second direction away from the rear glass 2400, and the rear packaging film 2220 is arranged on the side of the battery cell 2300 along the second direction close to the rear glass 2400. The projection of the front packaging film 2210 along the second direction on the rear glass 2400 overlaps with the projection of the battery cell 2300 along the second direction on the rear glass 2400, and the projection of the rear packaging film 2220 along the second direction on the rear glass 2400 overlaps with the projection of the battery cell 2300 along the second direction on the rear glass 2400.

[0059] See also Figures 1 to 4In some embodiments, the side of the second supporting member 1120 away from the third supporting surface 1121 along the second direction is the fourth supporting surface 1122, the distance D4 between the fourth supporting surface 1122 and the third supporting surface 1121 is less than the distance D1 between the first supporting surface 1111 and the third supporting surface 1121, and the distance D5 between the fourth supporting surface 1122 and the first supporting surface 1111 is greater than the distance D2 between the first supporting surface 1111 and the second supporting surface 1112, and the distance D6 between the fourth supporting surface 1122 and the second supporting surface 1112 is greater than or equal to a second value, which is the size of the front glass 2100 or the rear glass 2400 in the laminated assembly 2000 to be fixed in the second direction.

[0060] In this embodiment, the side of the second support member 1120 away from the third support surface 1121 along the second direction is set as the fourth support surface 1122, the distance D4 between the fourth support surface 1122 and the third support surface 1121 is smaller than the distance D1 between the first support surface 1111 and the third support surface 1121, and the distance D5 between the fourth support surface 1122 and the first support surface 1111 is larger than the distance D2 between the first support surface 1111 and the second support surface 1112, so that the fourth support surface 1122 is located on the side of the third support surface 1121 away from the first support surface 1111 along the second direction, and is located in the second direction. , a height difference is generated between the fourth supporting surface 1122 and the second supporting surface 1112; by setting the distance D6 between the fourth supporting surface 1122 and the second supporting surface 1112 to be greater than or equal to the second value, the second value is the size of the front plate glass 2100 or the rear plate glass 2400 in the laminated assembly 2000 to be fixed in the second direction, so that the staff can make the front plate glass 2100 / the rear plate glass 2400 contact with the second supporting surface 1112 on one side along the second direction, so that the other side of the front plate glass 2100 / the rear plate glass 2400 on the second direction is flush with the fourth supporting surface 1122 in the second direction or forms a height difference.

[0061] See also Figures 1 to 4 In some embodiments, a venting gap 1130 is provided on one side of the second support member 1120 close to the first support member 1110 along the first direction. The venting gap 1130 is configured as follows: provided between the second support member 1120 and the battery cell 2300 to separate the battery cell 2300 from the second support member 1120. The dimension D7 of the venting gap 1130 in the first direction is between 1 mm and 10 mm.

[0062] In this embodiment, an exhaust gap 1130 is set, and the exhaust gap 1130 is set between the second support member 1120 and the battery cell 2300 to separate the battery cell 2300 and the second support member 1120, so that when the subsequent laminating equipment laminates the laminating assembly 2000, the gap between the front glass 2100 and the packaging film 2200 on the side of the battery cell 2300 facing away from the rear glass 2400 is squeezed. After the gas in the laminating assembly 2000 is discharged from the laminating assembly 2000 through the gap between the front glass 2100 and the packaging film 2200 on the side of the battery cell 2300 facing away from the rear glass 2400, it enters the exhaust gap 1130 and is discharged from the laminating tooling 1000 from the exhaust gap 1130, thereby ultimately reducing the risk of a large number of bubbles being generated at the misaligned position of the front glass 2100 and the rear glass 2400.

[0063] See also Figures 1 to 4 In some embodiments, the first support member 1110 and the second support member 1120 are both made of heat-resistant materials.

[0064] In this embodiment, by setting the materials of the first support member 1110 and the second support member 1120 to be heat-resistant materials, the first support member 1110 / the second support member 1120 can be prevented from being softened by the high temperature generated when the laminator laminates the laminated assembly 2000, and the first support member 1110 / the second support member 1120 can be prevented from sticking to the laminator and elastically deforming along the second direction under the pressure of the laminator, thereby ensuring that the distance between the third support surface 1121 and the second support surface 1112 in the second direction remains unchanged, so that when one end of the front glass 2100 along the first direction contacts the third support surface 1121 and the other end contacts the packaging film 2200 on the side of the battery cell 2300 facing away from the rear glass 2400, there is always a gap between the front glass 2100 and the packaging film 2200 on the side of the battery cell 2300 facing away from the rear glass 2400.

[0065] See also Figures 2 to 5 In some embodiments, the lamination tooling 1000 includes a lamination frame 1200, and the lamination frame 1200 includes a first frame 1210. The first frame 1210 is arranged on a side of the second support member 1120 that is away from the first support member 1110 along the first direction. The first frame 1210 extends along a third direction, and the third direction is perpendicular to the first direction and the second direction. A first gap 1300 is provided between a side of the first frame 1210 close to the second support member 1120 and a side of the third support surface 1121 that is away from the first support member 1110 along the first direction.

[0066] In this embodiment, the laminating frame 1200 includes a first frame 1210, and the first frame 1210 is arranged on the side of the second support member 1120 away from the first support member 1110 along the first direction, so that the staff can install or remove the front glass 2100 and the second support member 1120 by moving the position of the first frame 1210; by setting the first frame 1210 close to the side of the second support member 1120 and the side of the third support surface 1121 away from the first support member 1110 along the first direction, a first gap 1300 is provided, which can prevent the laminating machine from being damaged. When laminating the laminated assembly 2000, part of the front packaging film 2210 between the front glass 2100 and the battery cell 2300 flows into the gap between the front glass 2100 and the third supporting surface 1121 under the squeezing of the laminator. Then, since there is no gap between the third supporting surface 1121 and the first frame 1210, the front packaging film 2210 is bonded to the first frame 1210, thereby preventing the laminated assembly 2000 from bonding to the first frame 1210. After lamination, the laminated assembly 2000 can be easily removed from the first frame 1210, and the second support member 1120 can be separated from the front glass 2100.

[0067] See also Figures 2 to 5 In some embodiments, the laminate frame 1200 includes a second frame 1220, which is arranged on a side of the first support member 1110 that is away from the second support member 1120 along the first direction. The second frame 1220 extends along the third direction. A second gap 1400 is provided between the side of the second frame 1220 close to the first support member 1110 and the side of the second support surface 1112 that is away from the second support member 1120 along the first direction.

[0068] In this embodiment, the laminating frame 1200 includes a second frame 1220, and the second frame 1220 is arranged on the side of the first support member 1110 away from the second support member 1120 along the first direction, so that the staff can install or remove the front glass 2100 and the first support member 1110 by moving the second frame 1220; by setting the second frame 1220 close to the side of the first support member 1110 and the second support surface 1112 along the first direction away from the second support member 1120, a second gap 1400 is provided between the laminating machine 2100 and the first support member 1110. When laminating the laminated assembly 2000, part of the rear encapsulation film 2220 between the rear glass 2400 and the battery cell 2300 flows into the gap between the rear glass 2400 and the second supporting surface 1112 under the extrusion of the laminator. Then, since there is no gap between the second supporting surface 1112 and the second frame 1220, the rear encapsulation film 2220 is bonded to the second frame 1220, thereby preventing the laminated assembly 2000 from bonding to the second frame 1220. After lamination, the laminated assembly 2000 can be easily removed from the second frame 1220, and the first support member 1110 can be separated from the rear glass 2400.

[0069] See also Figures 2 to 5 In some embodiments, a dimension D8 of the first gap 1300 in the first direction is between 5 mm and 20 mm.

[0070] In this embodiment, by setting the dimension D8 of the first gap 1300 in the first direction to be between 5 mm and 20 mm, the dimension of the lamination frame 1200 in the first direction can be reduced, thereby making it easier for the staff to place the lamination frame 1200 fixed with the lamination assembly 2000 into the chamber of the laminator, thereby reducing the space occupied by the lamination frame 1200 in the chamber of the laminator.

[0071] In some embodiments, a dimension D9 of the second gap 1400 in the first direction is between 5 mm and 20 mm.

[0072] In this embodiment, by setting the dimension D9 of the second gap 1400 in the first direction to be between 5 mm and 20 mm, the dimension of the lamination frame 1200 in the first direction can be reduced, thereby making it easier for the staff to place the lamination frame 1200 fixed with the lamination assembly 2000 into the chamber of the laminator, thereby reducing the space occupied by the lamination frame 1200 in the chamber of the laminator.

[0073] See also Figures 2 to 5 In some embodiments, the laminate frame 1200 includes a third frame 1230 and a fourth frame 1240, and the third frame 1230 and the fourth frame 1240 are arranged one by one on opposite sides of the support assembly 1100 along the third direction, and are both located between the first frame 1210 and the second frame 1220. One end of the third frame 1230 is connected to the first frame 1210, and the other end is connected to the second frame 1220. One end of the fourth frame 1240 is connected to the first frame 1210, and the other end is connected to the second frame 1220.

[0074] In this embodiment, by setting one end of the third frame 1230 to be connected to the first frame 1210 and the other end to be connected to the second frame 1220, and one end of the fourth frame 1240 to be connected to the first frame 1210 and the other end to be connected to the second frame 1220, the first frame 1210 and the second frame 1220 can be connected, so that the staff can easily remove the laminated assembly 2000 from the first frame 1210 and the second frame 1220 at the same time, and complete the separation of the first support member 1110 and the rear glass 2400, and the separation of the second support member 1120 and the front glass 2100.

[0075] By arranging the third frame 1230 and the fourth frame 1240 in a one-to-one correspondence and at intervals on the opposite sides of the support assembly 1100 along the third direction, it is convenient for the laminator to laminate the laminate assembly 2000. The front packaging film 2210 between the front plate glass 2100 and the battery cell 2300 and the rear packaging film 2220 between the rear plate glass 2400 and the battery cell 2300 flow out of the laminate assembly 2000 under the pressure of the laminator and are discharged from the laminating tool 1000 through the gap between the support assembly 1100 and the third frame 1230 and the fourth frame 1240; When the laminated component 2000 is formed, part of the front packaging film 2210 between the front glass 2100 and the battery cell 2300, and part of the rear packaging film 2220 between the rear glass 2400 and the battery cell 2300 are squeezed by the laminator. Since there is no gap between the supporting component 1100 and the third frame 1230 and the fourth frame 1240, they are bonded to the third frame 1230 and the fourth frame 1240, thereby preventing the laminated component 2000 from bonding to the third frame 1230 and the fourth frame 1240. As a result, the laminated component 2000 is difficult to be separated from the third frame 1230 and the fourth frame 1240 after lamination.

[0076] In some embodiments, the front glass 2100 and the back glass 2400 have the same size in the third direction, and the first support member 1110 and the second support member 1120 have the same size in the third direction and are both larger than the size of the front glass 2100 in the third direction.

[0077] See also Figures 2 to 5 In some embodiments, a distance between a side of the third frame 1230 close to the support assembly 1100 along the third direction and a side of the support assembly 1100 close to the third frame 1230 along the third direction is between 0 and 5 mm.

[0078] In this embodiment, by setting the distance between the side of the third frame 1230 close to the support assembly 1100 along the third direction and the side of the support assembly 1100 close to the third frame 1230 along the third direction to be between 0 and 5 mm, the size of the lamination frame 1200 in the third direction can be reduced, thereby making it easier for the staff to place the lamination frame 1200 with the lamination assembly 2000 fixed thereon into the chamber of the laminator, thereby reducing the space occupied by the lamination frame 1200 in the chamber of the laminator.

[0079] In some embodiments, a distance between a side of the fourth frame 1240 close to the support assembly 1100 along the third direction and a side of the support assembly 1100 close to the fourth frame 1240 along the third direction is between 0 and 5 mm.

[0080] In this embodiment, by setting the side of the fourth frame 1240 close to the support assembly 1100 along the third direction and the side of the support assembly 1100 close to the fourth frame 1240 along the third direction to be between 0 and 5 mm, the size of the lamination frame 1200 in the third direction can be reduced, thereby making it easier for the staff to place the lamination frame 1200 with the lamination assembly 2000 fixed thereon into the chamber of the laminator, thereby reducing the space occupied by the lamination frame 1200 in the chamber of the laminator.
