Description

Technical Field

[0001] The utility model relates to the field of photovoltaic components, in particular to a photovoltaic component lamination auxiliary component and a photovoltaic component lamination device. Background Art

[0002] With the development of the photovoltaic industry, the production efficiency of photovoltaic modules continues to improve. The degree of automation determines the manufacturing cost of photovoltaic modules. The use of automation to replace manual work has become an important means for the entire photovoltaic industry to continuously improve its competitiveness.

[0003] The lamination process in the manufacture of photovoltaic modules is to place the already laminated photovoltaic semi-finished modules (such as tempered glass, EVA, battery string array, EVA, and backplane) with the laminated silicone sheet between the upper and lower chambers of the laminator. When the module enters the laminator for vacuuming and lamination, all the bubbles generated by the melting of EVA are squeezed out, and the EVA is fully cross-linked by pressurizing, and the EVA bonds the tempered glass, battery string, and backplane together to form a whole.

[0004] The structure of the double-glass module is a five-layer structure of glass, film, battery string, film, and glass. During the lamination process, the film is heated to melt and flow to squeeze out all the bubbles in the laminated component to the edge of the photovoltaic module glass. Due to the lamination pressure, the thickness of the film at the edge of the photovoltaic module will become lower. After being exposed to harsh external environments, the module is prone to delamination, PID failure and other abnormalities. Therefore, a lamination frame is usually added to the double-glass module to prevent overpressure problems and ensure the overall thickness of the edge of the photovoltaic module.

[0005] The existing lamination line requires at least two people to place the frames and one person to take the frames. Frequent handling of the lamination frames causes frame deformation, increasing the risk of frame explosion and puncture of the silicone sheet. Utility Model Content

[0022] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings.

Figure 3 The structure in which a spring connects a lamination frame and a silicone plate fixing frame according to an embodiment of the present disclosure is schematically shown.

[0024] Please refer to Figure 1 In one embodiment of the present disclosure, the photovoltaic module lamination auxiliary component includes a lamination frame 40, a silicone plate fixing frame 50 and a plurality of springs 60. The springs 60 connect the lamination frame 40 and the silicone plate fixing frame 50, and pull the lamination frame 40 in the force balance direction to keep the lamination frame 40 in the first rectangular area 51 surrounded by the silicone plate fixing frame 50. The lamination frame 40 includes a plurality of units 41, and each unit 41 surrounds a second rectangular area 42.

[0025] In one embodiment, please refer to Figure 1, the silicone plate fixing frame 50 encloses a first rectangular area 51, the laminating frame 40 is arranged in the first rectangular area 51, and at least one pair of opposite sides of the laminating frame 40 are respectively connected to the sides of the silicone plate fixing frame 50 through springs 60. For example, the silicone plate fixing frame 50 includes a pair of long sides 52 extending along the first direction D1 and a pair of short sides 53 extending along the second direction D2 perpendicular to the first direction D1. The long sides 52 of the silicone plate fixing frame 50 and the short sides 53 of the silicone plate fixing frame 50 enclose the first rectangular area 51, and the laminating frame 40 is arranged in the first rectangular area 51. The two side sides of the laminating frame 40 extending along the first direction D1 are respectively connected to the long sides 52 of the silicone plate fixing frame 50 through springs 60. The long sides 52 and the short sides 53 of the silicone plate fixing frame 50 can be detachably connected, for example, by bolts. The outer contour of the laminating frame 40 is rectangular, and its two longer sides are connected to the long sides 52 of the silicone plate fixing frame 50 through springs 60. The laterally tensioned spring 60 pulls the laminating frame 40 from a symmetrical position so that the laminating frame 40 is suspended in the silicone plate fixing frame 50. Each spring 60 is of equal length and made of the same material, and has the same tensile length. The tension on both sides of the laminating frame 40 is balanced, and the laminating frame 40 is kept on a horizontal plane and in the center of the silicone plate fixing frame 50. Selecting a spring 60 of suitable material and tensile length can prevent the laminating frame 40 from shaking left and right during movement. Those skilled in the art can select the material and tensile length of the spring 60 by experiment. The silicone plate fixing frame 50 and the laminating frame 40 can be installed and disassembled as a whole, which will bring certain conveniences. For example, when the silicone plate 30 needs to be replaced, it is only necessary to release the connection between the silicone plate fixing frame 50 and the upper box 10 without removing each spring 60.

[0026] In one embodiment, springs 60 are symmetrically arranged on opposite sides of the laminating frame 40, and the springs 60 are stretched laterally. The laminating frame 40 is placed flat below the upper box 10, and the springs 60 extend laterally, that is, the laminating frame 40 is subjected to a lateral pulling force from the springs 60 in a symmetrical direction in the horizontal direction. The lateral tension of the springs 60 can reduce the vertical bouncing and left-right shaking of the laminating frame 40.

[0027] Please refer to Figure 2In one embodiment, the laminating frame 40 includes a plurality of units 41, each unit 41 defining a second rectangular area 42. The length and width of the second rectangular area 42 are slightly larger than the length and width of the part to be laminated, respectively, so as to accommodate the part to be laminated. These units 41 of the laminating frame 40 are arrayed, for example, all the units 41 of the laminating frame 40 are sequentially arranged in a single row in the first direction D1. Specifically, the long side of the second rectangular area 42 extends along the second direction D2, and the short side of the second rectangular area 42 extends along the first direction D1. The first direction D1 can be used as the feeding direction of the part to be laminated. Specifically, a plurality of parts to be laminated enter the laminating device along the first direction D1, and are lined up along the first direction D1, and each part to be laminated stops directly below a second rectangular area 42 accordingly. When the upper box 10 is pressed down, the laminating frame 40 falls synchronously, and each part to be laminated can be surrounded by a unit 41.

[0028] All units 41 of the laminate frame 40 are connected as a whole. Figure 2 In the illustrated embodiment, the laminate frame 40 comprises a pair of long straight sides 43 parallel to each other and extending continuously, and a pair of short straight sides 44 respectively connecting the two ends of the pair of long sides 52, the pair of long straight sides 43 and the pair of short straight sides 44 constitute a rectangular frame, and a plurality of intermediate rods 45 connected to the pair of long straight sides and parallel to the pair of short straight sides are provided in the rectangular frame, and the intermediate rods 45 divide the area in the rectangular frame into a plurality of second rectangular areas 42. The short straight sides 44 and the long straight sides 43, and the intermediate rods 45 and the long straight sides 43 can be connected by welding, or can be detachably connected by fasteners. The long straight sides 43 are complete rods extending along the first direction D1, and the short straight sides 44 extend along the second direction D2.

[0029] Optionally, adjacent second rectangular areas 42 share a middle rod 45 .

[0030] Optionally, two middle rods 45 close to each other are arranged between adjacent second rectangular areas 42 .

[0031] In other specific embodiments, each unit 41 of the laminate frame 40 is connected as a whole by a detachable connector. After the connector is removed, all units 41 of the laminate frame 40 can be separated into independent smaller rectangular frames. The laminate frame of this embodiment is not illustrated in the drawings.

[0032] In one embodiment, each unit 41 or part of the units 41 of the lamination frame 40 is physically separated from each other. For example, each unit 41 is in the shape of a rectangular frame, independent of each other and not connected to each other. The lamination frame of this embodiment is not illustrated in the drawings.

[0033] Figure 3 The schematic diagram shows the connection structure of the spring 60, the lamination frame 40 and the silicone plate fixing frame 50 according to an embodiment of the present disclosure. Figure 3 In one embodiment, the laminating frame 40 is provided with a first connection hole 46, the silicone plate fixing frame 50 is provided with a second connection hole 54, and the two ends of the spring 60 are respectively connected to the first connection hole 46 and the second connection hole 54.

For example, please refer to Figure 4 The photovoltaic module laminating machine includes an upper box 10, and the photovoltaic module laminating auxiliary components are horizontally arranged just below the upper box 10. The upper box 10 has a chamber 11 with a mouth facing downward, and the mouth of the chamber 11 is covered with a silicone plate 30, and the silicone plate 30 is fixed at the edge of the mouth by a silicone plate fixing frame 50. The laminating frame 40 is fixed just below the upper box 10 by a spring 60, so that it can fall synchronously with the closing of the upper box 10.

[0035] Further references Figure 1 In one embodiment, the chamber 11 of the upper box 10 is inflated with gas, which can expand and bulge the silicone plate 30, and apply pressure to the laminated parts placed on the horizontal plane to squeeze out the bubbles in the molten packaging glue. The silicone plate fixing frame 50 extends along the edge of the mouth of the chamber 11, presses on the silicone plate 30, and is fixed to the upper box 10. Optionally, additional sealing treatment can be performed between the edge of the mouth of the chamber 11 and the silicone plate 30 to prevent gas leakage in the chamber 11.

[0036] In one embodiment, if Figure 4 As shown, a photovoltaic assembly heating plate 20 for heating is provided below the upper box 10 , and the photovoltaic assembly 90 is arranged on the heating plate 20 . An upper high-temperature cloth 70 and a lower high-temperature cloth 80 are provided above and below the photovoltaic assembly 90 , respectively.

[0037] The laminating machine using the photovoltaic module lamination auxiliary component disclosed in the present invention does not require manual placement of lamination frames for each laminated component. Instead, after a number of laminated components are conveyed to a predetermined position below the upper box 10, the lamination frame 40 is allowed to drop as a whole onto the platform where the components to be laminated are located during the closing process of the upper box 10. In one operation, the various units 41 of the lamination frame 40 can be put around the periphery of all the components to be laminated.

[0038] The laminating frame 40 and the silicone plate fixing frame 50 are connected as one body, and the laminating frame 40 can be installed on the upper box 10 together when the silicone plate fixing frame 50 is installed on the upper box 10. When replacing the silicone plate 30, it is only necessary to release the connection between the silicone plate fixing frame 50 and remove the silicone plate fixing frame 50 and the laminating frame 40 together, without having to remove the silicone plate fixing frame 50 and the laminating frame 40 separately twice, thus saving operation time.

[0039] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
