Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, in particular to a circular multi-station stacked grid cell sheet preparation device. Background Art

[0002] The stacked-grid battery uses a current collection layer with the same current transmission direction to replace the main grid and fine grid in the traditional battery structure. The current collection layer is a conductive layer that forms good contact with the battery surface to collect the current generated by the battery. The conductive layer is distributed in a graphic form on the positive and / or negative electrode of the battery. The collected current is extracted through conductive wires. The conductive wires are wires that form good contact with the current collection layer to extract the current longitudinally and conduct it laterally. The wires are distributed in a graphic form on the positive and / or negative electrode of the battery. The structure in which the current collection layer is covered with conductive wires and the two form good contact is the stacked-grid structure. A workstation of the currently used stacked-grid battery welding machine combines multiple processes, which is cumbersome to operate and has low production efficiency. Utility Model Content

At the loading and unloading station, the battery cell is adsorbed on the No. 1 roller 4. After the loading process is completed, the No. 1 roller 4 rotates to the winding station, and the No. 2 roller 4 rotates to the loading and unloading station. At the winding station, the conductive wire is wound around the current collection layer. After the winding process is completed, the No. 1 roller 4 rotates to the welding station, and the No. 2 roller 4 rotates to the loading and unloading station. Drum 4 rotates to the winding station, and the conductive wire is welded to the current collection layer at the welding station. After the welding process is completed, roller 4 rotates to the coating and curing station, and roller 4 rotates to the welding station. UV glue is applied to the welding point between the conductive wire and the current collection layer at the coating and curing station. After the coating and curing process is completed, roller 4 rotates to the cutting station, and roller 4 rotates to the coating and curing station. The conductive wire is cut at the cutting station.

[0030] like Figures 2 to 4 As shown, the axis of the bearing surface 8 is parallel or colinear with the axis of the rotating shaft 5 .

[0031] like Figures 2 to 4 As shown, the surface of the carrying surface 8 is evenly distributed with adsorption holes 9, and the adsorption holes 9 can be connected to a vacuum generator, so that the battery cell is adsorbed on the carrying surface 8 by vacuum adsorption, which is simple and convenient to operate. Example 2

[0032] like Figures 2 to 4 As shown, the difference from Example 1 is that the circular multi-station stacked grid battery cell preparation device disclosed in this embodiment also includes a groove 10, which is arranged on the supporting surface 8 or the peripheral side surface 7, and the groove 10 has a groove main body extending from one side surface 7 to the other side surface 7; the groove 10 is arranged between two adjacent battery cells, and the groove 10 is arranged on the supporting surface 8 or the peripheral side surface 7, and the bus bar is placed in the groove 10 at the loading and unloading station.
