[0043] The working principle of this utility model:

[0044] like Figure 1 As shown, the direction of the arrow indicating X or the opposite direction of the arrow is the X-axis direction, and the direction of the arrow indicating Y or the opposite direction of the arrow is the Y-axis direction.

[0045] In this embodiment, the flower basket 5 can buffer or output multiple battery cells. The lifting drive 10 causes the lifting plate 9 to move up and down, thereby driving the flower basket 5 to move up and down. The lifting drive 10 can be a motor or a lifting belt. The motor drives the lifting belt, thereby driving the lifting plate 9 to move up and down. The synchronous belt 11 is at a fixed height. When the lifting plate 9 descends, it is equivalent to the synchronous belt 11 lifting the corresponding battery cell in the flower basket 5 and transporting the battery cell in the X-axis direction. This embodiment is... Figure 1The two upper feeding conveyors 1 transport baskets 5 from left to right, which is the feeding direction of basket 5. The two lower unloading conveyors 5 transport baskets 5 from right to left, which is the unloading direction of basket 5. During the feeding process, basket 5 passes through feeding conveyor 1, first transfer conveyor 4, first discharge conveyor 3, and is transported manually or by belt to the lifting platen 9, completing the feeding process. During the unloading process, basket 5 passes through lifting platen 9 and is transported manually or by belt to the first discharge conveyor 3, first transfer conveyor 4, and unloading conveyor 2. During the buffering process, basket 5 passes through lifting platen 9, descends to its lowest point, and is transported manually or by belt to the second discharge conveyor 12, second transfer conveyor 13, and buffer belt 14. Multiple first transfer conveyor belts 4 can move along the first Y-axis guide rail 41, and multiple second transfer conveyor belts 13 can move along the second Y-axis guide rail 131. A belt (not shown in this embodiment) may be installed on the top of the lifting platen 9 to transport the basket 5 on the lifting platen 9 to the first discharge belt 3 or to the second discharge belt 12. After the loading process of the basket 5 is completed, the basket 5 descends with the lifting platen 9 and outputs all the battery cells, becoming an empty basket 5. It can then be output to the second transfer conveyor belt 13 via the corresponding second discharge belt 12, and then moved to the Y-axis position via the second Y-axis guide rail 131. Finally, it is transported to the lifting platen 9 opposite to another second discharge belt 12, so that the empty basket 5 can be raised to re-collect or gather the processed battery cells. In this embodiment, part of the synchronous belt 11 is located above the lifting platen 9, that is, part of the synchronous belt 11 passes through the basket 5, and the width of the synchronous belt 11 is less than the distance between two opposite buffer bars 6 in the same group, so as to avoid interference with the synchronous belt 11 when the buffer bars 6 move up and down; or the width of the synchronous belt 11 is less than the closest distance between two opposite grooves 7 in the same group. In this embodiment, the flower basket 5 may be equipped with an interceptor or an interceptor bar at the rear, so that the flower basket 5 can only output or receive battery cells in one direction.
