[0036] As Figures 1 to 5As shown, the embodiment provides an edge sealing auxiliary tool, which comprises a main body 10 and a clamping structure 30. The main body 10 is provided with a mounting wheel 21 and a limiting wheel 23. The mounting wheel 21 is used to deploy the edge sealing tape. The edge sealing tape can extend to one side of the limiting wheel 23 via the mounting wheel 21 and adhere to the side surface of the photovoltaic laminate. The clamping structure 30 is arranged on the main body 10 and located on the side of the limiting wheel 23 away from the mounting wheel 21. The edge sealing tape is pressed on the edge of the main plane of the photovoltaic laminate under the action of the clamping structure 30. The clamping distance of the clamping structure 30 is adjustable.

[0037] The edge sealing refers to the use of the edge sealing tape to paste and wrap the edge of the photovoltaic laminate. Taking the flat photovoltaic laminate as an example, the photovoltaic laminate has two oppositely arranged main planes and a side surface arranged between the two main planes. The main plane refers to the light-receiving surface and / or the back surface of the photovoltaic laminate. The width of the edge sealing tape is greater than the thickness of the photovoltaic laminate. When the edge sealing tape is pasted on the side surface, there is still excess on the two side surfaces of the edge sealing tape, which needs to be smoothed and adhered to the edge of the two main planes of the photovoltaic laminate, respectively.

[0038] By arranging the mounting wheel 21 and the limiting wheel 23 on the main body 10, the edge sealing tape roll is mounted on the mounting wheel 21. The edge sealing tape is deployed and extends from the mounting wheel 21 to one side of the limiting wheel 23. One side of the limiting wheel 23 presses the edge sealing tape, so that the edge sealing tape can adhere to the side surface of the photovoltaic laminate. By arranging the clamping structure 30, the clamping structure 30 presses the edge sealing tape on the edge of the main plane of the photovoltaic laminate, without manual pasting, which helps to ensure the pasting effect. The clamping distance of the clamping structure 30 is adjustable, which can be suitable for photovoltaic laminates of different thicknesses.

[0039] Specifically, the main body 10 comprises a base 11 and a main support 12. The main support 12 is detachably connected with the base 11. The mounting wheel 21 is rotatably arranged on the main support 12, and the limiting wheel 23 is rotatably arranged on the base 11. One side of the base 11 is provided with the main support 12, and the limiting wheel 23 is exposed from the other side of the base 11 for guiding and pasting the edge sealing tape. The photovoltaic laminate can be a semi-finished laminate.

Since the limiting side plates of the two limiting wheels 23 are different in size, when the edge sealing tape is pasted on the photovoltaic laminated material, the contact areas of the two limiting wheels 23 with the photovoltaic laminated material and the side surface of the edge sealing tape are different, and the adhesion of the edge sealing tape can be gradually improved with the movement of the edge sealing auxiliary tool.

[0043] In the embodiment, the guide wheel 22 is provided with two guide wheels 22, which are a first guide wheel 221 and a second guide wheel 222, the first guide wheel 221 is rotatably arranged on the main support 12, and the second guide wheel 222 is rotatably arranged on the limiting portion 113 of the base 11 and located at the slot opening of the limiting slot.

When the edge sealing auxiliary tool advances along the edge of the photovoltaic laminated glass, the mounting wheel 21 and the mounting shaft rotate, the force is transmitted to the recovery wheel shaft and the recovery wheel 24 through the synchronous belt 25, so that the recovery wheel 24 rotates synchronously with the mounting wheel 21, and the recovery effect of the isolation layer is achieved.

[0050] In order to fix the isolation layer on the recovery wheel 24, the recovery wheel 24 is provided with a fixing buckle 241, and the fixing buckle 241 is used to fix the end of the isolation layer on the recovery wheel 24. By arranging the fixing buckle 241 on the recovery wheel 24, the end of the isolation layer is fixed by the fixing buckle 241. When the mounting wheel 21 rotates, the recovery wheel 24 rotates and drives the end of the isolation layer to move under the action of the synchronous belt 25, so that the isolation layer can be wound on the recovery wheel 24.
