Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic laminating equipment, and particularly relates to a laminating frame for a solar cell module. Background Art

[0002] The laminate of a photovoltaic module is formed by laminating a front transparent cover plate, a front adhesive film, a battery string, a rear adhesive film, and a rear cover plate under high temperature and pressure to form a composite layer. During lamination, a rectangular laminating frame is placed around the laminate to protect the laminate. Before the conveying mechanism of the laminator conveys the laminate into the laminator, it is necessary to manually place the laminating frame around each laminate one by one, which is inefficient. Summary of the Invention

[0003] To solve at least one technical problem of the prior art, the present invention provides a laminating frame for a solar cell module.

[0004] According to one aspect of the present invention, there is provided a laminating frame for a solar cell module, including a rectangular outer frame. Within the area surrounded by the rectangular outer frame, there are a plurality of detachable partition bars. The partition bars divide the area surrounded by the rectangular outer frame into a plurality of sub-regions arranged in the length direction of the rectangular outer frame. At both ends of each sub-region in the width direction of the rectangular outer frame, there are provided detachable adjusting blocks. The adjusting blocks define a working area smaller than the sub-region within the sub-region.

[0005] During lamination, the photovoltaic module laminate is placed in the working area. The laminating frame of this embodiment adopts an integrated structure. When applied, the laminating frame can be installed on the upper chamber of the laminator. As the upper chamber and the lower chamber of the laminator are closed, the laminating frame can synchronously fall around the laminate. Since the partition bars are detachably connected to the rectangular outer frame, the partition bars can be disassembled to adjust the installation position of the partition bars, so that the width of the working area can be adjusted. The distance between the adjusting blocks on the opposite sides of the sub-region defines the length of the working area. Since the adjusting blocks are detachable, adjusting blocks of different sizes can be replaced, and thus the length of the working area is also adjustable. Therefore, the size of the working area of the laminating frame of this embodiment can be adjusted by adjusting the position of the partition bars and / or by installing adjusting blocks of different sizes, so that the solar cell module laminating frame can be applicable to the lamination of photovoltaic semi-finished components of different formats.

[0006] In some embodiments, the adjusting block has a first straight edge facing the inner side of the sub-region and parallel to the length direction of the rectangular outer frame. The first straight edges of the adjusting blocks at both ends of the sub-region and the partition bars on both sides of the sub-region define the working area within the sub-region.

[0007] In some embodiments, the rectangular outer frame includes a pair of parallel long rods and a pair of parallel short rods. The partition rod is disposed within the area enclosed by the rectangular outer frame. The two ends of the partition rod are respectively connected to the pair of long rods and are parallel to the short rods. The long rods, short rods, and partition rod are made of aluminum alloy profiles. Since the long rods and short rods are made of aluminum alloy profiles, this provides great flexibility for the installation of the partition rod. For example, disassemblable fasteners such as corner brackets and bolts can be used to connect the partition rod to the long rod, thereby facilitating the adjustment of the installation position of the partition rod.

[0008] In some embodiments, each end of the sub-region has two adjusting blocks, and the two adjusting blocks are respectively disposed at the top corners of the sub-region.

[0009] In some embodiments, the adjusting block is connected to the rectangular outer frame by bolts.

[0010] In some embodiments, the adjusting block further has a second straight edge opposite to and parallel to the first straight edge. There is a region lacking material between the first straight edge and the second straight edge, and there is a through hole between the region lacking material and the second straight edge. The adjusting block is connected to the rectangular outer frame by a fastener passing through the through hole.

[0011] In some embodiments, corner guards are respectively provided at the four outer top corners of the rectangular outer frame. The corner guards surround the outer top corners of the rectangular outer frame, and the parts of the contour of the corner guards that do not contact the rectangular outer frame are arc-shaped. Since the outer contour of the corner guards is arc-shaped, damage to the silicone plate of the laminator by the lamination frame of the solar cell module is avoided.

[0012] In some embodiments, the corner guard has an arc shape on the outside, and there is a right-angle notch on the inside of the corner guard. The outer top corner of the rectangular outer frame fits with the right-angle notch, and the corner guard is connected to the rectangular outer frame by fasteners.

[0013] In some embodiments, connectors are provided on the outside of the rectangular outer frame.

[0014] In some embodiments, the rectangular outer frame is formed by splicing aluminum alloy profiles. The connector includes a connection base, a connection shaft, and a flexible connector. The connection base is connected to the rectangular outer frame by fasteners. The connection shaft is fixed on the connection base, and one end of the flexible connector is connected to the connection shaft.

[0015] In some embodiments, the flexible connector is a Teflon tape.

[0016] In some embodiments, the lamination frame can be configured into a first configuration and a second configuration, and the first configuration and the second configuration have a rectangular outer frame of the same size. In the first configuration, the area inside the rectangular outer frame is equally divided into 7 sub-regions by 6 partition bars. The width of the sub-region in the first configuration is w1, and in the length direction of the sub-region, the distance between the adjusting blocks is d1. In the second configuration, the area inside the rectangular outer frame is divided into 6 sub-regions and a non-working area by 5 partition bars. The width of the sub-region in the second configuration is w2, and in the length direction of the sub-region, the distance between the adjusting blocks is d2, and the width of the non-working area is w3. Among them, w1 < w2, 0 ≤ w3 < w2, and d1 < d2. When laminating a photovoltaic laminate with a smaller size, the first configuration of the lamination frame can be adopted. When laminating a photovoltaic laminate with a larger size, the second configuration of the lamination frame can be adopted, which is applicable to the lamination of photovoltaic laminates of various sizes.

[0029] Refer to Figure 1, the present invention provides a lamination frame for a solar cell module, including a rectangular outer frame 1. Within the area surrounded by the rectangular outer frame 1, there are multiple detachable partition rods 2. The partition rods 2 divide the area surrounded by the rectangular outer frame 1 into multiple sub-regions 10 arranged in the length direction of the rectangular outer frame 1. At both ends of each sub-region 10 in the width direction of the rectangular outer frame 1, there are respectively provided detachable adjustment blocks 3. The adjustment blocks 3 define a working area 101 smaller than the sub-region 10 within the sub-region 10.

[0030] During lamination, a photovoltaic module laminate is placed in the working area 101. Since the partition rod 2 is detachably connected to the rectangular outer frame 1, the partition rod 2 can be removed to adjust the installation position of the partition rod. In this way, the width of the working area 101 can be adjusted. The distance between the adjustment blocks 3 on the opposite sides of the sub-region 10 defines the length of the working area 101. Since the adjustment blocks 3 are detachable, adjustment blocks 3 of different sizes can be replaced, and thus the length of the working area 101 is also adjustable. Therefore, the lamination frame of this embodiment can adjust the size of the working area 101 by adjusting the position of the partition rod 2 and / or by installing adjustment blocks 3 of different sizes, so that the lamination frame of the solar cell module can be suitable for laminating photovoltaic semi-finished modules of different formats. The configuration of the lamination frame of this embodiment is adjustable, making the lamination frame have good dimensional adaptability, and there is no need to customize lamination frames separately for products of various sizes, saving costs.

[0031] Exemplarily, the rectangular outer frame 1 includes a pair of parallel long rods 11 and a pair of parallel short rods 12. The partition rods 2 are arranged within the area surrounded by the rectangular outer frame 1. Both ends of the partition rod 2 are respectively connected to the pair of long rods 11 and are parallel to the short rods 12. The long rods 11, short rods 12, and partition rods 2 are made of aluminum alloy profiles to facilitate the installation and disassembly of the lamination frame of the solar cell module. The long rods 11 and short rods 12 are spliced into a rectangular outer frame through components such as corner brackets.

[0032] Exemplarily, the partition rod 2 is arranged within the area surrounded by the rectangular outer frame 1. The partition rod 2 is parallel to the short side of the rectangular outer frame 1, such as the short rod 12. That is, both ends of the partition rod 2 are respectively vertically connected to the long sides of the rectangular outer frame 1, such as the long rods 11 at both ends of the partition rod 2.

[0033] Since the long rods 11 and short rods 12 are made of aluminum alloy profiles, this provides greater flexibility for the installation of the partition rod 2. For example, detachable fasteners such as corner brackets and bolts can be used to connect the partition rod 2 to the long rod 11, thereby facilitating the adjustment of the installation position of the partition rod 12.

[0034] Exemplarily, please refer to Figure 3, on the side of the long rod 11 facing the sub-region 10, there is a first connection card slot 111 extending along the length direction of the long rod 11, and on the other side opposite to the first connection card slot 111, there is a second connection card slot 112. The first connection card slot 111 can be used to connect the partition rod 2.

[0035] Exemplarily, please refer to Figure 2 , the adjusting block 3 has a first straight edge 31 facing the inner side of the sub-region 10 and parallel to the length direction of the long rod 11. The first straight edges 31 of the adjusting blocks 3 at both ends of the sub-region 10 and the partition rod 2 define the working area 101 within the sub-region 10.

[0036] Optionally, there are 2 adjusting blocks 3 provided at each end of the sub-region 10. The adjusting blocks 3 can be set at the top corners of the sub-region, that is, at the right-angle positions formed by the partition rod 2 and the long rod 11, or can be set at positions away from the top corners of the sub-region.

[0037] Exemplarily, as Figure 2 shown, the adjusting block 3 further has a second straight edge 32 opposite to and parallel to the first straight edge 31, and the second straight edge 32 is in contact with the long rod 11 of the rectangular outer frame 1.

[0038] Exemplarily, the adjusting block 3 is connected to the rectangular outer frame 1 by bolts. For example, the adjusting block 3 is connected at the first connection card slot 111.

[0039] Exemplarily, as Figure 2 shown, there is a region 33 lacking material between the first straight edge 31 and the second straight edge 32, and there is a through hole 34 between the region 33 lacking material and the second straight edge 32. The adjusting block 3 is connected to the rectangular outer frame 1 by fasteners passing through the through hole 34. The setting of the region 33 lacking material facilitates the installation of the adjusting block 3 onto the long rod 11.

[0040] Exemplarily, in order to prevent the corners of the adjusting block 3 from damaging the photovoltaic semi-finished component, the outer corners of the adjusting block 3 facing the photovoltaic semi-finished component are rounded.

[0041] In some examples, the lamination frame can be configured into a first configuration and a second configuration, and the first configuration and the second configuration have a rectangular outer frame 1 of the same size. As Figure 1 shown, in the first configuration, the inside of the rectangular outer frame 1 is equally divided into 7 sub-regions 10 by 6 partition rods 2. The width of the sub-region 10 in the first configuration is w1, and in the length direction of the sub-region 10, the distance from the adjusting block 3 to the short side of the sub-region 10 is d1. As Figure 4As shown, in the second configuration, the area within the rectangular outer frame 1 is divided into six sub-regions 10 and one non-working region 102 by five partition bars 2. The width of the sub-region 10 in the second configuration is w2, and the width of the non-working region 102 is w3. In the length direction of the sub-region 10, the distance from the adjustment block 3 to the short side of the sub-region 10 is d2; where w1 < w2, 0 ≤ w3 < w2, and d1 < d2.

[0042] When laminating smaller-sized photovoltaic laminates, the first configuration of the laminating frame can be adopted. When laminating larger-sized photovoltaic laminates, the second configuration of the laminating frame can be adopted. The first configuration can laminate seven smaller laminates simultaneously, and the second configuration can laminate six larger laminates simultaneously. When switching from the first configuration to the second configuration, the extra area within the rectangular outer frame 1 serves as the non-working region 102.

[0043] For example, the basic distance between the short bars 12 can be 8496 mm, and the basic spacing between the long bars 11 can be 2519 mm. In the first configuration, seven partition bars 2 can equally divide the area within the rectangular outer frame 1 into seven sub-regions 10 with basic dimensions of 2519×1188 mm. By constructing the dimensions of the adjustment block 3 such that the basic spacing between the adjustment blocks 3 on opposite sides is 2332 mm, that is, the basic dimensions of the working region 101 are 2332 mm×1188 mm. Thus, the first configuration is suitable for laminating laminates with basic dimensions of 2272×1128 mm.

[0044] Alternatively, in the first configuration, seven partition bars 2 can equally divide the area within the rectangular outer frame 1 into seven sub-regions 10 with basic dimensions of 2519×1188 mm. By constructing the dimensions of the adjustment block 3 such that the basic spacing between the adjustment blocks 3 on opposite sides is 2436 mm, that is, the basic dimensions of the working region 101 are 2436 mm×1188 mm. Thus, the first configuration is suitable for laminating laminates with basic dimensions of 2376×1128 mm.

[0045] When the adjustment block 3 is removed, the sub-region 10 and the working region 101 are of the same size, with basic dimensions of 2519×1188 mm. Thus, it is suitable for laminating laminates with basic dimensions of 2459×1128 mm.

[0046] In the second configuration, six partition bars 2 can divide the area within the rectangular outer frame 1 into six sub-regions 10 with basic dimensions of 2519×1357 mm. By constructing the dimensions of the adjustment block 3 such that the basic spacing between the adjustment blocks 3 on opposite sides is 2436 mm, that is, the basic dimensions of the working region 101 are 2436 mm×1357 mm. Thus, the second configuration is suitable for laminating laminates with basic dimensions of 2378 mm×1297 mm.

[0047] It should be noted that the width of the sub-region 10 and the spacing between the adjusting blocks 3 on the opposite sides can be selected within an appropriate range above and / or below the basic dimension. For example, it can be selected within the range of ±20 mm of the basic dimension. Further, it can be selected within the range of ±15 mm of the basic dimension. Further, it can be selected within the range of ±10 mm of the basic dimension. Further, it can be selected within the range of ±5 mm of the basic dimension. Further, it can be selected within the range of ±2 mm of the basic dimension.

[0048] Please refer to Figure 5 , corner guards 5 are respectively provided at the four outer top corners of the rectangular outer frame 1. The corner guards 5 surround the outer top corners of the rectangular outer frame 1, and the parts of the contour of the corner guards 5 that do not contact the rectangular outer frame 1 are arc-shaped.

[0049] By installing the corner guards 5 at the four outer corners of the rectangular outer frame 1 in the present invention, damage to the silicone plate of the laminator caused by the solar cell module lamination frame is avoided.

[0050] Further, the corner guard 5 has an arc-shaped outer side and a right-angled notch on the inner side. The outer top corner of the rectangular outer frame 1 fits with the right-angled notch, and the corner guard 5 is connected to the rectangular outer frame 1 through fasteners such as bolts. For example, the corner guard 5 is respectively connected to the long rod 11 and the short rod 12 at the outer top corner by bolts. At this time, the corner guard 5 can serve as the function of an angle bracket, that is, the four corner guards 5 can be spliced into the rectangular outer frame 1 by using the long rod 11 and the short rod 12. In order to avoid friction between the bolts and the silicone plate of the laminator, the holes for installing the bolts are countersunk holes.

[0051] Please refer to Figure 6 , a connecting member 4 is provided on the outer side of the rectangular outer frame 1, and the solar cell module lamination frame is detachably installed on the member 6 of the laminator through a plurality of connecting members 4. The connecting members 4 are evenly distributed along the long side and the short side of the rectangular outer frame 1.

[0052] Exemplarily, the connecting member 4 includes a connecting seat 41, a connecting shaft 42 and a flexible connecting member 43. The connecting seat 41 is connected to the rectangular outer frame 1 by screws. The connecting shaft 42 is fixed on the connecting seat 41. One end of the flexible connecting member is connected to the connecting shaft 42, and the other end is used to connect the laminator. Among them, the flexible connecting member 43 is made of polytetrafluoroethylene cloth.

[0053] Exemplarily, the rectangular outer frame 1 is spliced by aluminum alloy profiles. The rectangular outer frame 1 includes a pair of parallel long rods 11 and a pair of parallel short rods 12. The partition rod 2 is arranged in the area surrounded by the rectangular outer frame 1. The two ends of the partition rod 2 are respectively connected to the pair of long rods 11 and are parallel to the short rods 12. On the outer sides of the long rods 11 and the short rods 12, that is, the sides opposite to the sub-region 10, a second connecting card slot 112 is provided. The connecting seat 41 can be bolted to the second connecting card slot 112.

[0054] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present invention. Various modifications to the above-described embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
