Description

Technical Field

[0001] The utility model relates to the technical field of transport mechanisms, and in particular to a transport mechanism and a marking and welding integrated machine for battery cells. Background Art

[0002] The function of the cell transport mechanism is to pick up the cell from the placement position, move it to the retrieval position, and then provide for the action of other mechanisms. In the prior art, the cell transport mechanism generally has two transport components, and its specific operation process is as follows: 1. The cell is first placed on the first transport component, and the second transport component waits for the cell to be placed directly below the first transport component; 2. As the cell placed on the first transport component moves to the retrieval position, the second transport component rises to place the cell; 3. After the cell placed on the first transport component is removed from the retrieval position, the first transport component returns to the placement position, while the second transport component moves down to avoid the first transport component and moves to the retrieval position to wait for the cell to be removed; 4. After the cell placed on the second transport component is removed, the second transport component descends again and moves to the placement position, while the first transport component places the cell at the placement position and moves to the retrieval position to wait for the cell to be removed; 5. This action is repeated multiple times. The above cell transport mechanism requires multiple sets of power mechanisms, is relatively complex in structure, and is costly.
