[0056] Embodiment 3

[0057] The embodiment provides a method for sticking an adhesive tape. The adhesive tape 4 has a first section and a second section, and an opening 9 penetrates through the first surface and the second surface. The method comprises the following steps:

[0058] A first force is applied to the second section of the adhesive tape 4 in a direction from the first surface into the opening, so that the adhesive tape 4 is bent, wherein the first section is fixed on the first surface, and the second section extends to the opening 9 (i.e., the second section of the adhesive tape is suspended at the opening) ;

[0059] Air is blown by an air blowing mechanism, so that a second force is applied to the bent second section to bend the second section towards the second surface;

[0060] The part of the bent second section of the adhesive tape towards the second surface is pressed to the second surface by a pressing mechanism.

[0061] The method in the embodiment further comprises the following steps: fixing the first section of the adhesive tape 4 on the first surface by an initial sticking mechanism, and extending the second section to the opening 9.

[0062] Specifically, in the present embodiment, when the double-sided adhesive tape 4 is pasted on the opening 9 on the backsheet 11 of the photovoltaic module, the first step is the preliminary pasting of the adhesive tape 4 on the first surface of the backsheet 11, including: two negative pressure suction parts 3 of the manipulator 1 respectively air-suck an adhesive tape 4 from the adhesive tape outlet mechanism, then one negative pressure suction part 3 of the manipulator 1 pastes the pasting section (i.e. the first section) of the adhesive tape 4 on one side of the opening 9, and the movable section (i.e. the second section) is laid on the opening 9, then the manipulator 1 rotates to control the other negative pressure suction part 3 to paste the pasting section (i.e. the first section) of the adhesive tape 4 on the other side of the opening 9, and the movable section (i.e. the second section) is laid on the opening 9, and the preliminary pasting of the adhesive tape 4 on the backsheet 11 is shown in FIG. 6. Figure 2 As a variable implementation, the first section of the adhesive tape 4 can be manually fixed on the first surface, and the second section can be stretched to the opening 9 (i.e. the second section of the adhesive tape is suspended at the opening).

[0063] The second step is the bending and turning of the second end of the adhesive tape 4 from the first surface to the second surface of the backsheet 11, including: the punch 2 of the manipulator 1 is provided with two blow gaps 5 which are respectively inclined to two sides and are in communication with the air supply channel 8, during the descending of the punch 2 or after the punch 2 is lowered to a set position (for example, the air outlet of the blow gap passes through the opening from the first surface), the air flow of the corresponding blow gap 5 blows the corresponding adhesive tape 4 to bend on the second surface, and with the continuous descending of the punch 2, the adhesive tape 4 is blown to be closer to the second surface, and the process is shown in FIG. 7. Figure 3

[0064] The last step is to press and paste the adhesive tape 4 bent on the second surface on the second surface, including: the punch 2 continues to descend, and the pressing part 6 of the pressing mechanism rises, since the end face of the pressing part 6 is provided with the avoiding space 7 for avoiding the punch 2, the punch 2 can descend into the avoiding space 7 of the pressing part 6 without interference, when the pressing part 6 rises to the pressing surface and contacts the second surface, the adhesive tape 4 bent on the second surface is pressed and pasted on the second surface, when the end of the punch body 14 contacts the first surface, the adhesive tape 4 on the first surface is also pressed and pasted on the first surface, and the pasting is completed, and the schematic diagram is shown in FIG. 8. Figure 4

[0065] Obviously, the above embodiment is only an example for clear illustration, and is not a limitation on the implementation. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the implementations. The obvious changes or variations derived therefrom are still within the protection scope of the present application.​​
