[0030] Among them, receiving table 100 is used to receive battery string 10, battery string 10 is located on support plate 101, first fork transport mechanism 200 lifts battery string 10 on receiving table 100 from the clearance of adjacent two support plates 101, stepwise to transfer platform 300 fork transport. Figure 5As shown, the first fork transport mechanism 200 includes a first horizontal driving member 210, a first lifting driving member 220, a first connecting plate 230 and a plurality of first fork teeth 240. The driving end of the first horizontal driving member 210 is connected to the first lifting driving member 220, and the driving end of the first lifting driving member 220 is connected to the first connecting plate 230. The plurality of first fork teeth 240 are arranged on the first connecting plate 230 at intervals along the second direction. The first horizontal driving member 210, the first lifting driving member 220 and the first connecting plate 230 are located below the plurality of support plates 101. The plurality of first fork teeth 240 are interspersed between the plurality of support plates 101. The battery string 10 is transported by the first fork teeth 240, and the avoidance openings on the return baffle 110 and the transfer platform 300 are used to avoid the first fork teeth 240. During the process of forking the battery string 10, the first fork transport mechanism 200 uses the alignment baffle 110 to align the long side of the battery string 10. First, the alignment baffle 110 is raised, and the first fork transport mechanism 200 forks the battery string 10 so that one side of the battery string 10 hits the alignment baffle 110, thereby aligning the long side of the battery string 10. Then, the alignment baffle 110 is lowered, and the first fork transport mechanism 200 forks the battery string 10 with the aligned long side onto the transfer platform 300. The positioning camera 310 takes pictures to locate the two ends of the battery string 10 on the transfer platform 300, and calculates the deviation between the positions of the two ends of the battery string 10 and the preset position. The string arrangement mechanism 500 grabs the battery string 10 on the transfer platform 300 and moves the battery string 10 in the second direction based on the position deviation.

The glass sheet 20 enters the battery string layout device from the feed conveyor mechanism 800. The second fork transport mechanism 900 forks the glass sheet 20 onto the discharge conveyor mechanism 400 in a step-by-step manner. The string arrangement mechanism 500 arranges the battery strings 10 in the same position each time. After the string arrangement mechanism 500 arranges a string of battery strings 10 on the glass sheet 20, the second fork transport mechanism 900 forks the glass sheet 20 forward once until the glass sheet 20 is fully filled with battery strings 10.
