When the first carrying mechanism 3 picks up the battery string and places it on the first tray 21 again, the newly placed battery string and the previous battery string are separated by the isolation paper, so that the blue film surface of the newly placed battery string is not scratched.
[0034] As shown in Figure 1 and Figure 2 , in some embodiments, the second tray 22 is arranged below the first tray 21, the second tray 22 is slidingly installed on the support 1 in the horizontal direction, the support 1 is provided with a first driving member 24, and the first driving member 24 is configured to drive the second tray 22 to move horizontally to the position directly below the first tray 21 or move out from the position below the first tray 21.
[0035] When the second tray 22 needs to be used, the first driving member 24 moves the second tray 22 out from below the first tray 21, and the second tray 22 can work normally, improving the flexibility of the equipment.
[0036] As shown in Figure 2 and Figure 3 In some embodiments, the bracket 1 includes a first mounting plate 11 and a second mounting plate 12, the first mounting plate 11 is fixed on the bracket 1, a transmission block 13 is slidingly installed on the first mounting plate 11 in the horizontal direction, and the first driving member 24 is installed on the first mounting plate 11; the second tray 22 is slidingly installed on the second mounting plate 12 in the horizontal direction, a connecting rod 14 is arranged between the second tray 22 and the transmission block 13, the top end of the connecting rod 14 is fixed on the second tray 22, and the bottom end of the connecting rod 14 is fixed on the transmission block 13; the first driving member 24 is configured to drive the transmission block 13 to reciprocally slide in the horizontal direction, so as to drive the second tray 22 to move in the horizontal direction. Since the second tray 22 only needs to move back and forth between two positions, the first driving member 24 can be a gas cylinder, which is low in cost and high in efficiency
[0037] By arranging the second tray 22 on the first mounting plate 11 and arranging the first driving member 24 and the transmission block 13 on the second mounting plate 12, the first mounting plate 11 is located directly above the second mounting plate 12, so that the first driving member 24 does not need additional installation space, further reducing the floor space occupied by the second tray 22 and related components.
[0038] As shown in Figure 3 In some embodiments, the second mounting plate 12 is provided with a sliding rail 16 and a sliding block 15 in the horizontal direction, the sliding block 15 is slidingly installed on the sliding rail 16, the first end of the second tray 22 is fixedly installed on the sliding block 15, and the second mounting plate 12 is provided with a roller 17 for supporting the second end of the second tray 22. The second end of the second tray 22 is supported by the roller 17 of the second mounting plate 12, which ensures the stability of the second tray 22 when it is suspended above the first mounting plate 11, avoiding the problem of unstable sliding of the second tray 22 when the floor space is reduced.
[0039] As shown in Figure 2As shown, in some embodiments, the battery string collecting device further comprises a third tray 23 for carrying unqualified battery strings, and the second carrying mechanism 4 is further configured to pick up the isolation paper from the second tray 22 and place it on the third tray 23; the third tray 23 and the first tray 21 are arranged in a horizontal direction, the third tray 23 is lower than the second tray 22, and the first driving member 24 is configured to drive the second tray 22 to move horizontally to be directly below the first tray 21 or to move horizontally to be directly above the third tray 23. By arranging the second tray 22 between the first tray 21 and the third tray 23, the floor space of the second tray 22 coincides with the floor space of the first tray 21 and the third tray 23, reducing the total floor space of the first tray 21, the second tray 22 and the third tray 23, so that the battery string collecting device can be adapted to more space-limited application scenarios.
[0040] It should be noted that, as can be seen from Figure 2 , the third tray 23 is located between the first mounting plate 11 and the second mounting plate 12, and when the transmission block 13 drives the connecting rod 14 to slide horizontally, the third tray 23 will not interfere with the connecting rod 14, so it will not affect the horizontal sliding of the second tray 22, and the importance of the roller 17 at the second end of the second mounting plate 12 is also reflected, which supports the second tray 22 in the air to ensure that the second tray 22 can slide to be directly above the third tray 23.

Figure 4 The sheet material below the first picking assembly 31 is the battery string, and the sheet material below the second picking assembly 41 is the isolation paper.
[0042] The first picking assembly 31 forms a negative pressure area on the surface of the battery string, thereby sucking the battery string, and the first driving assembly 32 and the second driving assembly 33 drive the first picking assembly 31 to slide horizontally and ascend or descend vertically, so as to move the battery string to a predetermined position.

[0044] The second pickup assembly 41 moves the separator paper to a predetermined position by forming a negative pressure area on the surface of the separator paper, and then adsorbing the separator paper, and the third driving assembly 42 and the fourth driving assembly 43 drive the second pickup assembly 41 to slide horizontally and lift vertically.
[0045] In some embodiments, as shown in Figure 4 The first carrying mechanism 3 includes a first sliding seat, and the second carrying mechanism 4 includes a second sliding seat, which are slidingly installed on the support 1 in the horizontal direction. The first sliding seat and the second sliding seat share a set of slide rails 16. The first driving assembly 32 is configured to drive the first sliding seat to reciprocate in the horizontal direction, and the third driving assembly 42 is configured to drive the second sliding seat to reciprocate in the horizontal direction. The first pickup assembly 31 and the second driving assembly 33 are installed on the first sliding seat, and the second pickup assembly 41 and the fourth driving assembly 43 are installed on the second sliding seat. The first driving assembly 32 can adopt a pulley assembly. The first sliding seat is fixed on one side of the belt of the first driving assembly 32, and a motor is used to drive the belt to slide horizontally, so as to drive the first pickup assembly 31 and the first sliding seat to slide in the horizontal direction through the first driving assembly 32. The second driving assembly 33 can adopt an electric cylinder, which drives the first pickup assembly 31 to lift vertically to any height within the stroke. The third driving assembly 42 can also adopt a pulley assembly, and a motor is used to drive the belt to slide horizontally, so as to drive the second sliding seat and the second pickup assembly 41 to slide horizontally. The fourth driving assembly 43 can also adopt an electric cylinder.
[0046] By sharing a set of slide rails 16 by the first sliding seat and the second sliding seat, the cost of the equipment is saved, and the horizontal sliding reference of the first carrying mechanism 3 and the second carrying mechanism 4 is coincided, which reduces the difficulty of installation and debugging.
[0047] In some embodiments, as shown in Figure 4 The first pickup assembly 31 and the second pickup assembly 41 each include a plurality of groups of suction cups arranged in the horizontal direction. Each group of suction cups of the first pickup assembly 31 is used to adsorb one battery piece by negative pressure, and the plurality of groups of suction cups of the second pickup assembly 41 cooperate to adsorb one separator paper by negative pressure.
