Automatic cutting-unwinding and spot welding device for battery nickel strip

Abstract

The invention discloses an automatic cutting-unwinding and spot welding device for a battery nickel strip. The automatic cutting-unwinding and spot welding device is characterized by comprising a closed track, a plurality of rotary conveying assemblies moving along the closed track, a cutting-unwinding mechanism and a spot welding mechanism; each rotary conveying assembly comprises a supporting rod, a rotary cylinder and a nickel strip positioning plate; the cutting-unwinding mechanism comprises a rotating shaft, unwinding rolls, a synchronous conveying assembly and a circulating pulling and cutting assembly, wherein the circulating pulling and cutting assembly comprises a square guide track located above the closed rail, a plurality of hanging rods which move along the square guide rail are hung on the square guide rail, a lower pressing plate is arranged at the bottom of each hanging rod, an upper pressing plate is arranged on each hanging rod in a sliding mode, pressing strips are arranged below the upper pressing plate, and cutters are arranged on the two side walls of the upper pressing plate respectively. According to the automatic cutting-unwinding and spot welding device for the battery nickel strip provided by the invention, the automatic cutting-unwinding and spot welding of the nickel strip is achieved in the manufacturing process of a parallel connection net of thenickel strip, production efficiency is improved; and meanwhile, labor intensity of workers is greatly reduced.

Description

technical field [0001] The invention relates to the field of lithium battery manufacturing, in particular to a battery nickel strip automatic cutting and spot welding device. Background technique [0002] An important step in the production process of lithium-ion batteries is the spot welding of nickel strips, and the lithium-ion cells are connected in series and parallel by nickel strips. The spot welding of nickel strips is to weld at the intersection of each nickel strip so that the nickel strips form a parallel network. Afterwards, multiple lithium-ion batteries are connected in parallel to the network, and then they are packaged in the box. However, in the prior art, in the process of making the nickel strip and connecting it to the network, the nickel strip on the nickel strip roll is manually laid on the nickel strip positioning plate, and then welded with an electric soldering iron, and the labor intensity of the workers is high. The production efficiency of nickel...
