In the battery string 1 corresponding to the string table 2 in the second embodiment, the end portion of the welding strip 12 is covered between the adhesive film 13 and the battery piece 11, so that the warping phenomenon is avoided, but the structure of the string table 2 is relatively complex.
In the first or second embodiment of the present invention, the membrane support stand 21 is a flexible structure such as sponge or rubber. After the adhesive film 13 is arranged on the film support table 21, the film support table 21 moves upwards, and in the process that the adhesive film 13 and the welding strip 12 move upwards to be in contact with the battery piece 11, the welding strip 12 is firstly in contact with the battery piece 11, the film support table 21 and the adhesive film 13 deform to cover the welding strip 12, and the film support table 21 continues to push the adhesive film 13 to enable the adhesive film 13 to be in full contact with the battery piece 11.

The adsorption hole is communicated with the negative pressure environment, and the adhesive membrane 13 can be adsorbed on the surface of the membrane supporting table 21.
As shown in fig. 9, in the first embodiment or the second embodiment of the present invention, the stringing platform 2 further includes a pressing block 24 located directly above two ends of each row of clamps 22, the top surface of the clamps 22 is a plane, the pressing block 24 can be moved out of the position directly above the clamps 22 along the direction away from the clamps 22, and the pressing block 24 may be a rubber block or a sponge block.
