In order to improve the stability of the solar cell string during the circulation process, in one embodiment, refer to Fig.11 The flip suction cup assembly 23 and / or the swing string suction cup assembly 45 include a suction cup 61 and a suction cup mounting seat 62 for mounting the suction cup 61, an air passage connected to the suction cup 61 is formed in the suction cup mounting seat 62, and the outer wall of the suction cup mounting seat 62 is provided with a plurality of air intake ports 63 connected to the air passage, any one of the air intake ports 63 can generate negative pressure in the suction cup 61 alone, so that when one of the air intake ports 63 is blocked, the other air intake port 63 can replenish the negative pressure in time, so that the solar cell string can be firmly adsorbed, thereby improving the stability of the solar cell string during the circulation process.

[0090] In addition, it should be noted that the suction cup 61 on the string swinging suction cup assembly 45 can be partially controlled. For example, part of the solar cell string can be placed on the glass plate first, and then the other part of the solar cell string can be adjusted so that the solar cell strings of the above parts can be better positioned on the glass plate. During the position adjustment process of the solar cell string, an auxiliary positioning camera assembly 7 is required to take pictures. In one embodiment, the automatic flipping string swinging machine 100 also includes a positioning camera assembly 7. The positioning camera assembly 7 includes a camera disposed on the frame 1 and located at the string swinging station 12, which is used to position the solar cell string on the glass plate. This arrangement facilitates the accurate positioning of the solar cell string on the glass plate.

[0091] In one embodiment, for example, the solar cell assembly includes 6 strings of solar cell strings, and the flipping assembly 2 is used to simultaneously grasp and flip the 6 strings of solar cell strings. After the flipping is completed, the swinging assembly 4 is used to first swing and position 3 strings of solar cell strings, and after the positions are adjusted, the swinging and positioning of the other 3 strings of solar cell strings are achieved, so that the above-mentioned 6 strings of solar cell strings are accurately positioned relative to each other and also accurately positioned relative to the glass plate.

[0092] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention's specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
