AI Technical Summary
When traditional car seat back panel welding equipment is used on curved or convex/concave back panels, the initial height of the positioning rods is not uniform, resulting in uneven pressure. This causes local deformation or shaking of the back panel during welding, leading to problems such as weld point misalignment and incomplete welds.
It employs multiple elastic lifting components and adjustment components. The initial height of the support screw is adjusted through a worm gear structure. Combined with the spring of the elastic lifting component, it provides uniform pressure to ensure that the rubber block matches the curved surface of the back plate. Stable lifting is achieved through the sliding groove and internal thread sleeve. It is also equipped with a cylinder to drive the lifting plate and the jet pipe for precise welding.
This achieved stable positioning of the backplate during the welding process, reduced weld point misalignment and incomplete welds, and improved welding quality and stability.
