Description

Technical Field

[0001] The utility model relates to the field of photovoltaic components, in particular to 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

The device of this embodiment does not need to manually place the laminating frame 40 for each laminated piece, but can be a plurality of laminated pieces are conveyed to the predetermined position below the upper box 10, so that the laminating frame 40 is integrally dropped onto the platform where the laminated pieces are located during the closing process of the upper box 10, and each unit 41 of the laminating frame 40 is sleeved on the periphery of the laminated pieces. The elastic band 60 is flexible and will not scratch the silicone plate 30. The material of the elastic band 60 can be rubber.

One end of the elastic band 60 is connected to the laminating frame 40, and the other end is connected to the silicone plate fixing frame 50. The chamber 11 of the upper box 10 is inflated with air, which can make the silicone plate 30 expand and bulge, and the pressure is applied 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.

[0029] In one embodiment, if Figure 1 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.

[0030] In one embodiment, the laminating frame 40 and the silicone plate fixing frame 50 are connected by an elastic band 60, and the laminating frame 40 can be installed on the upper box 10 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, thereby saving operation time.

[0031] In one embodiment, please refer to Figure 2, 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 side edges of the laminating frame 40 are respectively connected to the side of the silicone plate fixing frame 50 through the elastic band 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 pair of silicone plate fixing frames 50 and the short sides 53 of the pair of silicone plate fixing frames 50 enclose the first rectangular area 51, the laminating frame 40 is arranged in the first rectangular area 51, and the two side edges 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 the elastic band 60.
