The two gripper assemblies 30 are used to transport materials used for laying battery strings, and transport the materials on the second conveying mechanism 2 to the cache platform 4 and the first conveying mechanism 1 alternately in turn. The two gripper assemblies 30 work together to grab the materials on the second conveying mechanism 2 to the cache platform 4 and grab the materials on the cache platform 4 to the first conveying mechanism 1 respectively. The two gripper assemblies 30 carry materials alternately, which not only reduces the distance traveled by the materials, but also improves the efficiency of material transfer.

[0026] It should be noted that the materials used for laying the battery strings include battery cells, membranes, welding strips, and adhesive tapes, which are material structures that can be grasped and moved. During the process of laying the battery strings, the gripper assembly 30 can separately move and combine the battery cells, membranes, welding strips, and adhesive tapes to form a continuous battery string.

[0027] In some embodiments, the first conveying mechanism 1 and the second conveying mechanism 2 are horizontally arranged side by side, and the cache platform 4 is horizontally arranged between the first conveying mechanism 1 and the second conveying mechanism 2. Two gripper assemblies 30 are arranged side by side above the first conveying mechanism 1 and the second conveying mechanism 2 along a conveying direction perpendicular to the first conveying mechanism 1 and the second conveying mechanism 2, and are respectively used to grab materials on the second conveying mechanism 2 to the cache platform 4 and to grab materials on the cache platform 4 to the front end of the first conveying mechanism 1, and are combined with other battery string materials to lay out into a battery string. The two gripper assemblies 30 move synchronously. When one of the gripper assemblies 30 transports the material on the second conveying mechanism 2 to the cache platform 4, the other gripper assembly 30 synchronously transports the material on the cache platform 4 to the first conveying mechanism 1. In this way, the two gripper assemblies 30 work together to alternately grab and transport the same material twice to the first conveying mechanism 1, thereby improving the material transportation efficiency.
