[0047] Embodiment 1

[0048] This embodiment provides a photovoltaic module assembly device 100, including: a glass coating mechanism 110, for coating adhesive on a single side of a glass sheet;

[0049] The sheet-closing mechanism 120 is used to combine two glass sheets coated with adhesive and a battery string array, wherein the battery string array is located between the two glass sheets.

[0050] Reference Figure 1 The glass coating mechanism 110 can apply adhesive 300 to one side of the glass. Specifically, the glass coating mechanism 110 is arranged on a conveying surface for conveying glass, which can be a conveyor belt or other conveying structures. The glass coating mechanism 110 translates on the conveying surface to apply adhesive on the glass sheet.

[0051] Reference Figure 2 The glass sheet 200 may include a front glass 210 and a back glass 220, and the battery string array is placed between the front glass 210 and the back glass 220. The front glass 210 and the back glass 220 with the adhesive applied on them are placed facing each other, and the front glass 210 and the back glass 220 are glued together, and the battery string array is fixed between the front glass 210 and the back glass 220.

[0052] It is understandable that the front glass 210 and the back glass 220 can be the same glass sheet or two different glass sheets.

[0053] When implementing, refer to Figure 1 , one glass coating mechanism 110 can be provided to coat the front glass 210 and the back glass 220 with glue respectively, and then transport them in two lines. Alternatively, two glass coating mechanisms 110 can be provided to coat the front glass 210 and the back glass 220 with glue respectively, and then transport them in two lines.

[0054] After the front glass 210 is coated with glue, it continues to be transported forward and merges with the battery string array 400. The battery string array 400 is transported and placed on the front glass 210 (i.e., the side coated with the adhesive 300). The battery string array 400 and the front glass 210 continue to be transported forward and merge with the back glass 220. The back glass 220 is flipped 180° to the side coated with the adhesive 300 facing down, and then covered on the front glass 210, and the battery string array 400 is sandwiched between the back glass 220 and the front glass 210, and then the subsequent operations are continued.

[0055] A glass coating mechanism 110 and a sheet-closing mechanism 120 are provided. The glass coating mechanism 110 automatically sets different coating widths and thicknesses according to product requirements, and applies adhesive on the glass sheet, and then fixes the battery string array between two glass sheets through the sheet-closing mechanism 120. The glue coating area can be controlled according to requirements, and the degree of adaptation to the battery string array is high. It can also be conveniently switched to combine battery string arrays of various sizes, which is convenient to operate and is conducive to improving production efficiency.

[0056] Embodiment 2

[0057] On the basis of the first embodiment, the glass coating mechanism 110 includes a moving frame 111 and a coating blade head 112;

[0058] The mobile frame 111 can move perpendicularly to the extension direction of the mobile frame 111;

[0059] The coating blade head 112 is movably disposed on the movable frame 111 .

[0060] Reference Figures 1 to 4 In this embodiment, the coating blade 112 is used to apply adhesive on the glass sheet. The side of the glass sheet on which the adhesive is applied is the coating surface. The coating blade 112 is movably arranged on the movable frame 111 and moves along the extension direction of the movable frame 111 to apply the adhesive on the coating surface along the extension direction of the movable frame 111.

[0061] The moving frame 111 can move perpendicularly to the extension direction of the moving frame 111, so that the coating blade 112 can completely apply adhesive to the coating surface. For example, the moving frame 111 is arranged longitudinally, and the moving frame 111 can move transversely. The coating blade 112 arranged on the moving frame 111 moves longitudinally on the moving frame 111, and moves transversely on the driving frame of the moving frame 111, and the moving track can cover the entire coating surface of the glass sheet.

[0062] In one embodiment, on the placement plane of the glass sheet, slide rails 114 are arranged on both sides of the glass, and the moving frame 111 is a gantry frame, which is horizontally arranged on the placement plane of the glass sheet and can slide along the slide rails 114 on both sides of the glass sheet. A guide rail is arranged on the moving frame 111 along the extension direction of the moving frame 111, and a slider adapted to the guide rail is arranged on the coating blade 112, and the slider drives the coating blade 112 to reciprocate along the guide rail.

[0063] Reference Figure 7 In one embodiment, the coating blade 112 relies on the adhesive supply pipeline to provide adhesive. The coating blade 112 is plate-shaped and parallel to the placement plane of the glass sheet. The coating blade 112 has a glue outlet 1121 connected to the adhesive supply pipeline. The coating blade 112 is also provided with a guide groove 1122 connected to the glue outlet 1121, which can guide the adhesive to the bottom of the coating blade 112. While the coating blade 112 is moving and scraping, the adhesive is discharged from the coating blade 112 to the glass.

[0064] Embodiment 3

[0065] Reference Figures 1 to 4 On the basis of the second embodiment, the coating blade head 112 is movably arranged on the movable frame 111 through a telescopic component.

[0066] In this embodiment, the telescopic component can be extended or shortened, and the coating blade head 112 is connected to the movable frame 111 through the telescopic component. Under the action of the telescopic component, the distance between the coating blade head 112 and the glass sheet can be adjusted. When the telescopic component is extended, the distance between the coating blade head 112 and the glass sheet is reduced, and when the telescopic component is shortened, the distance between the coating blade head 112 and the glass sheet is increased.

[0067] The distance between the coating blade 112 and the glass sheet can be adjusted. When applying glue, the coating blade 112 is adjusted to an appropriate distance from the glass sheet to facilitate evenly applying the adhesive on the glass sheet. When the glue is applied, the coating blade 112 is adjusted to a farther distance from the glass sheet to avoid scratching the position where the glue has been applied when the coating blade 112 moves, resulting in uneven application of the adhesive.

[0068] Embodiment 4

[0069] On the basis of the second embodiment, a scraper is provided at the glue outlet 1121 of the coating blade head 112 .

[0070] In this embodiment, the scraper is disposed at the glue outlet 1121 of the coating blade 112 to scrape off the residual adhesive at the glue outlet 1121 .

[0071] During the gluing process, when one gluing stroke is completed and the next gluing stroke is performed, if there is adhesive remaining at the glue outlet 1121, when the next gluing stroke is performed, it is easy to cause adhesive accumulation at the starting position of the stroke, resulting in thicker adhesive at this position and uneven adhesive application.

[0072] Embodiment 5

[0073] Reference Figure 1 , Figure 5 and Figure 6 On the basis of the first embodiment, the sheet closing mechanism includes a first transfer component and a second transfer component, the first transfer component can pick up the battery string array, and the second transfer component can transfer and flip the glass sheet.

[0074] In this embodiment, the first transfer component 121 picks up the welded battery string array 400 and places it on the front glass 210 coated with the adhesive 300, so that the front glass 210 and the battery string array 400 can be bonded together. The second transfer component 122 can transfer and flip the back glass sheet 200, and then flip the back glass 220 and cover it on the front glass 210.

[0081] The second moving component 1221 is used to drive the glass sheet to move and flip, and the second adsorption component 1222 is used to adsorb the glass sheet and can be flipped relative to the robot arm.

[0082] Specifically, refer to Figure 1 , Figure 5 and Figure 6 The second moving part 1221 may be a mechanical arm, and the second adsorption part 1222 may be a suction cup. The flipping may be realized by the flipping function of the mechanical arm itself, or the second adsorption part 1222 may be connected to the mechanical arm through a flipping part.

[0083] In one embodiment, a tray rack may be provided at the end of the robot arm, and a plurality of suction cups may be evenly arranged on the tray rack to make the glass sheet adsorbed more evenly and stably.
