NTC heating wire conductor automatic welding integrated equipment and welding method thereof

Abstract

This invention discloses an integrated automatic welding device and welding method for NTC heating wire conductors, belonging to the field of welding technology. Through the transmission of the conveying component, the clamping control component, in conjunction with the rail disc, can automatically clamp the U-shaped electrode and lead wire, ensuring the twisting and welding operations. When the second gear drives the arc-shaped rack, the clamping component can twist the U-shaped electrode and lead wire into a twisted composite structure before welding. This significantly increases the effective contact area between the U-shaped electrode and lead wire, significantly improving axial tensile strength and welding reliability, reducing the likelihood of loosening and incomplete welding. Furthermore, the entire clamping, positioning, and twisting action is coordinated with the conveying component, eliminating the need for multiple devices and complex transmission combinations. This results in a simple and compact mechanical structure, significantly reducing daily maintenance costs. It is highly adaptable to the high-volume, standardized, and low-cost automated welding production of NTC heating wires in the electric vehicle service industry chain.
