According to the main-grid-free battery string and the preparation method thereof disclosed by the invention, direct contact between a grid line and a welding strip is avoided by arranging a conducting layer, so that tin-silver alloy formed by grid line silver paste and tin on the welding strip during welding of the welding strip is avoided, the over-welding problem is reduced, and electric connection between the special-shaped grid line and the welding strip is avoided by arranging an insulating layer. Furthermore, the height of the conductive layer is larger than that of the insulating layer, so that the welding strength and the electric connection between the welding strip and the conductive layer are ensured. Or the height of the conductive layer is smaller than the height of the insulating layer by adopting a specific preparation process, and meanwhile, electric contact between the welding strip and the conductive layer is realized.

The present application discloses a method for converting a recycled developing cartridge. The recycled developing cartridge includes a cartridge body, the cartridge body including a developing roller and a first forced push piece. The method includes the steps of: removing at least part of the first forced push piece so that the converted developing cartridge can avoid a protrusion in a drum assembly and can move downward relative to the drum assembly when installed in the drum assembly; and installing a second cover on the cartridge body, the second cover including a second electrical contact surface, a second forced push piece, and a lifting assembly. The second electrical contact surface is fixed relative to the cartridge body. The second forced push piece is located at a fourth end in a second direction. The second forced push piece is configured to receive a pushing force from the drum assembly. The lifting assembly is configured to lift the developing cartridge upward relative to an image forming device when the converted developing cartridge and the drum assembly are detachably installed in the image forming device. The present application enables the recycled developing cartridge to be successfully adapted and applied to an existing image forming device, thereby maximizing resource utilization and significantly reducing costs.
