A lithium-ion cell parallel network automatic cutting spot welding device

Abstract

The invention discloses an automatic cut-and-place spot welding device for parallel networking of lithium-ion batteries, which is characterized in that it includes a closed track, a plurality of rotating transport components moving along the closed track, a cut-and-place mechanism and a spot welding mechanism; each rotating The transport assembly includes a support rod, a rotating cylinder, and a nickel belt positioning plate; the cutting and placing mechanism includes a cross bar, a discharge roll, a feeding assembly, a cutting knife and a pressing assembly, and the feeding assembly includes an upper conveyor belt and a lower conveyor belt, and the cutting knife slides up and down It is arranged at one end of the feeding assembly, and the pressing and pulling assembly includes a linear guide rail, a connecting rod, a lower pressing, and an upper pressing plate, and the upper pressing plate is slidably arranged on the connecting rod. The invention provides an automatic cut-and-place spot welding device for parallel networking of lithium-ion batteries, which realizes automatic cut-and-place spot welding of nickel strips during the production process of nickel strips for parallel networking, improves production efficiency, and at the same time greatly reduces Labor intensity of workers.

Description

technical field [0001] The invention relates to the field of lithium battery manufacturing, in particular to a spot welding device for automatically cutting and releasing lithium-ion batteries connected to a network. 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 ...

Problems solved by technology

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 strips in parallel is low
