Description

Technical Field

[0001] The invention relates to the technical field of laminating tooling, and in particular to a laminating tooling for a double-glass photovoltaic module. Background Art

[0002] During the lamination process, the edges and corners of photovoltaic modules are subjected to greater pressure, resulting in a significant extrusion of the packaging material in the middle of the module. After lamination, the thickness of the four sides and corners of the module is lower than the thickness in the middle of the module. During the aging test of such modules, the lack of packaging materials at the edges of the modules will cause water vapor intrusion, greatly affecting the aging performance and outdoor service life of the modules. Therefore, most mainstream manufacturers will use various lamination tools to slow down or avoid the phenomenon of insufficient glue or insufficient glue caused by excessive force on the edges and corners of the modules.

[0003] Laminating jigs are generally rectangular, and their thickness is basically the same as that of the component. Laminating jigs protect the components on all sides, which can well ensure the thickness of the edges and corners of the components after lamination. However, as the component format becomes larger and larger, the size of the laminating frame also increases. The maximum size of a laminating jig can reach 2.5*1.5m, making the transportation, storage and operation process extremely difficult.

[0004] Moreover, rectangular laminating tools can only be used for components of corresponding sizes, and laminating tools need to be replaced for components of different sizes, which is time-consuming and labor-intensive. Summary of the invention

[0005] The technical problem to be solved by the present invention is to solve the technical problem that the laminating tooling in the prior art is large in size, inconvenient for transportation and storage, and cannot be adjusted in size, and the laminating tooling needs to be replaced according to different module sizes when used. The present invention provides a laminating tooling for double-glass photovoltaic modules. The technical solution adopted by the present invention to solve the technical problem is: a laminating tooling for double-glass photovoltaic modules, comprising:

[0006] A left frame, the left frame comprising a left longitudinal beam, a first left cross beam and a second left cross beam, the first left cross beam and the second left cross beam are both located on the right side of the left longitudinal beam, and the first left cross beam and the second left cross beam are both perpendicular to the left longitudinal beam, the first left cross beam is movably disposed at the head end of the left longitudinal beam, and the second left cross beam is movably disposed at the end of the left longitudinal beam;

[0007] A right frame, the right frame is arranged on the right side of the left frame, the right frame and the left frame are symmetrically arranged along the center line thereof, the right frame comprises a right longitudinal beam, a first right transverse beam and a second right transverse beam, the first right transverse beam and the second right transverse beam are both located on the left side of the right longitudinal beam, and the first right transverse beam and the second right transverse beam are both perpendicular to the right longitudinal beam, the first right transverse beam is movably arranged at the head end of the right longitudinal beam, and the second right transverse beam is movably arranged at the end of the right longitudinal beam;

[0008] A connecting rod with a telescopic function, one end of the connecting rod is connected to the left longitudinal beam, and the other end is connected to the right longitudinal beam.

[0009] Optionally, the connecting rod is divided into a left connecting rod and a right connecting rod, and the left connecting rod and the right connecting rod are movably connected.

[0010] For the convenience of installation, a cylindrical protrusion is provided along the upper surface of the left longitudinal beam, and a circular hole is correspondingly provided on the left connecting rod. The left connecting rod is sleeved on the cylindrical protrusion of the left longitudinal beam through the circular hole, and the left connecting rod can rotate along the cylindrical protrusion.

[0011] In order to facilitate fixation, a square column is arranged along the upper surface of the right longitudinal beam, and a square hole is correspondingly arranged on the right connecting rod. The right connecting rod is sleeved on the square column of the right longitudinal beam through the square hole.

[0012] Preferably, the left longitudinal beam is pivotally connected to the first left transverse beam.

[0013] The left longitudinal beam is connected to the first left cross beam by a hinge, and the butt joint surface between the left longitudinal beam and the first left cross beam is a 45-degree inclined surface. The hinge axis is arranged on the upper surface of the left frame, and corresponds to the butt joint line between the left longitudinal beam and the first left cross beam, one hinge piece is connected to the left longitudinal beam, and the other hinge piece is connected to the first left cross beam. By connecting in this way, since the butt joint surface between the left longitudinal beam and the first left cross beam is a 45-degree inclined surface, the first left cross beam is folded along the inclined surface, and after folding, the first left cross beam and the left longitudinal beam overlap on a straight line, which can greatly reduce the floor space and facilitate storage and transportation.

[0014] Lamination tooling for double-glass photovoltaic modules also includes:

[0015] Corner sleeves are installed at the connection between the left longitudinal beam and the first left cross beam. The surface of the corner sleeve is an isosceles triangle, and the two right-angled sides of the corner sleeve are installed along the left longitudinal beam and the first left cross beam respectively. The middle part of the triangle contacts the corners of the component, exerting pressure on the corners, which can effectively alleviate the degree of warping of large-plate components entering the laminator and ensure high-quality lamination of the components.

[0016] Preferably, a flexible layer is further provided in the corner sleeve, and the flexible layer wraps the connection between the left longitudinal beam and the first left cross beam.

[0017] The left longitudinal beam is set as a hollow structure, and the first left cross beam and the second left cross beam are both set as solid structures; the right longitudinal beam is set as a hollow structure, and the first right cross beam and the second right cross beam are both set as solid structures. The cross beam is designed as a solid structure, and the cross beam has a large weight, which can tighten the flexible wrapping layer. At the same time, the weight of the lamination frame can also be used to apply a certain pressure to the four corners of the component, so that the warping of the four corners caused by the temperature difference when the component enters the laminator is effectively alleviated.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The laminating tooling of the present application is small in size and easy to operate. The frame structure of the entire laminating tooling is folded to overlap into a straight line where two longitudinal beams are located, which can greatly reduce the floor space and facilitate storage and transportation;

[0020] 2. It can effectively alleviate the warping degree of large-plate components entering the laminator, ensuring high-quality lamination of components;

[0021] 3. One person can complete the laying work on one side of the laminator alone, which is simple and convenient to operate;

[0022] 4. The width of the laminating tooling can be adjusted according to the width of the component to achieve the effect of "one mold for multiple uses". BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0032] like Figures 1 to 5 As shown, it is the best embodiment of the present invention, a laminating tool for double-glass photovoltaic modules, comprising:

[0033] The left frame 10 includes a left longitudinal beam 11, a first left cross beam 12 and a second left cross beam 13. The first left cross beam 12 and the second left cross beam 13 are both located on the right side of the left longitudinal beam 11, and the first left cross beam 12 and the second left cross beam 13 are both perpendicular to the left longitudinal beam 11. The first left cross beam 12 is movably disposed at the head end of the left longitudinal beam 11, and the second left cross beam 13 is movably disposed at the end of the left longitudinal beam 11;

[0034] The right frame 20 is arranged on the right side of the left frame 10. The right frame 20 and the left frame 10 are symmetrically arranged along the center line thereof. The right frame 20 includes a right longitudinal beam 21, a first right transverse beam 22 and a second right transverse beam 23. The first right transverse beam 22 and the second right transverse beam 23 are both located on the left side of the right longitudinal beam 21, and the first right transverse beam 22 and the second right transverse beam 23 are both perpendicular to the right longitudinal beam 21. The first right transverse beam 22 is movably arranged at the head end of the right longitudinal beam 21, and the second right transverse beam 23 is movably arranged at the end of the right longitudinal beam 21;

[0035] The connecting rod 30 has a telescopic function, one end of the connecting rod 30 is connected to the left longitudinal beam 11, and the other end is connected to the right longitudinal beam 21. The connecting rod 30 is divided into a left connecting rod 31 and a right connecting rod 33, and the left connecting rod 31 and the right connecting rod 33 are fixed in the middle with a round screw.

[0036] like Figure 1 and Figure 4 As shown, a cylindrical protrusion 14 is provided along the upper surface of the left longitudinal beam 11 , and a circular hole 32 is correspondingly provided on the left connecting rod 31 . The left connecting rod 31 is sleeved on the cylindrical protrusion 14 of the left longitudinal beam 11 through the circular hole 32 , and the left connecting rod 31 can rotate along the cylindrical protrusion 14 .

[0037] like Figure 1 and Figure 5As shown, a square column 24 is provided along the upper surface of the right longitudinal beam 21 , and a square hole 34 is correspondingly provided on the right connecting rod 33 . The right connecting rod 33 is sleeved on the square column 24 of the right longitudinal beam 21 through the square hole 34 .

[0038] like Figure 2 and Figure 3 As shown, the left longitudinal beam 11 is pivotally connected to the first left cross beam 12, and the left longitudinal beam 11 and the first left cross beam 12 are connected by hinges. The butt joint surfaces of the left longitudinal beam 11 and the first left cross beam 12 are both inclined surfaces inclined at 45 degrees. The hinge axis is arranged on the upper surface of the left frame 10 and corresponds to the butt joint line between the left longitudinal beam 11 and the first left cross beam 12. One hinge piece is connected to the left longitudinal beam 11, and the other hinge piece is connected to the first left cross beam 12.

[0039] The laminating tooling for double-glass photovoltaic modules of the present application also includes:

[0040] Corner sleeve 40 is sleeved at the connection between left longitudinal beam 11 and first left cross beam 12. The surface of corner sleeve 40 is an isosceles triangle. Two right angle sides of corner sleeve 40 are sleeved along left longitudinal beam 11 and first left cross beam 12 respectively. Figure 1 As shown, in this embodiment, corner sleeves are provided at the four corners, and the corner sleeves can also be connected to the corresponding brackets by bolts.

[0041] A flexible layer is also provided in the corner sleeve 40, and the flexible layer wraps the connection between the left longitudinal beam 11 and the first left cross beam 12. The flexible layer can be a connecting tape.

[0042] The left longitudinal beam 11 is configured as a hollow structure, and the first left cross beam 12 and the second left cross beam 13 are configured as solid structures; the right longitudinal beam 21 is configured as a hollow structure, and the first right cross beam 22 and the second right cross beam 23 are configured as solid structures.

[0043] The lengths of the left longitudinal beam 11 and the right longitudinal beam 21 are both 6 to 10 mm longer than the length of the component, so that a certain amount of space can be ensured inside the frame for the component to be easily exhausted after entering the laminator.

[0044] The laminating tool for the double-glass assembly of the present application can adjust the length of the connecting rod 30, so that the size of the laminating tool is suitable for the double-glass assembly. When the width of the assembly is smaller than the laminating tool, the left connecting rod 31 and the right connecting rod 33 of the laminating tool are in a V shape. The maximum size of the laminating tool is that the connecting rod 30 is stretched horizontally into a "one" shape. The laminating tool of the present application can be generally adapted to a variety of assembly sizes;

[0045] The crossbeam can be folded along a 45-degree slope. The folded crossbeam overlaps with the corresponding longitudinal beam. The crossbeam and the longitudinal beam are in a straight line, which can greatly reduce the footprint and facilitate storage and transportation.

[0046] The left connecting rod 31 is sleeved on the cylindrical protrusion 14 on the central surface of the left frame 10 through the circular hole 32 provided therein, and then the left connecting rod 31 is fixed to the left frame 10 through the nail cap. The square hole 34 of the right connecting rod 33 is sleeved on the square column 24 of the right frame 20. There are three square columns 24 on the right frame 20, and the right connecting rod 33 is correspondingly provided with three square holes 34. The square holes 34 are sleeved on the square columns 24 one by one to connect the right connecting rod 33 with the right frame 20. When it is necessary to store it, the position where the right connecting rod 33 is connected to the right frame 20 can be removed, and the left connecting rod 31 can be rotated along the cylindrical protrusion 14 of the left frame 10, so that the left connecting rod 31 and the right connecting rod 33 overlap with the left longitudinal beam 11 on a straight line, as shown in FIG. Figure 3 As shown, the left frame 10 and the connecting rod 30 are folded. It can be seen that the connecting rod 30 can be rotated along the cylindrical protrusion 14 to form a straight line, which effectively saves space.

[0047] In summary, the laminating tooling for double-glass components of the present application is folded multiple times to form a connecting rod 30, a first left crossbeam 12 and a second left crossbeam 13 that overlap on the left longitudinal beam 11, and a first right crossbeam 22 and a second right crossbeam 23 that overlap on the right longitudinal beam 21. The floor space of the entire laminating tooling is reduced from a frame structure to the floor space of two longitudinal beams, which can greatly reduce the floor space and facilitate storage and transportation. In addition, the laminating tooling for double-glass components of the present application can effectively alleviate the degree of warping of large-plate components entering the laminator, ensuring high-quality lamination of the components. A single person can complete the laying work on one side of the laminator, which is simple and convenient to operate. The width of the laminating tooling can be adjusted according to the width of the component to achieve the effect of "one mold for multiple uses".

The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
