AI Technical Summary

Technical Problem

Existing technologies for wrapping double-arc products in automotive interiors suffer from large manual deviations, low efficiency, resource waste, and quality problems. In particular, the leather material of double-arc products cannot be completely adhered, affecting aesthetics and texture.

Method used

A fully automated multi-arc wrapping device for automotive interior parts has been designed, including a support component, a placement component, an adhesive application component, and a pressing component. Through the coordinated action of a sliding cylinder, a rotating rod, a control cylinder, and a folding device, the device achieves precise bonding and edge folding of leather and plastic body.

Benefits of technology

It improved work efficiency, reduced costs, enhanced the quality and aesthetics of interior parts, and reduced the risk of human error.

Abstract

This invention relates to the field of interior trim covering technology, specifically to a fully automatic multi-arc covering equipment and process for automotive interior trim. During operation, the plastic body to be processed is placed on the lower mold. Then, a sliding cylinder is activated to move the lower mold below the adhesive application assembly. A feeding pump is activated to deliver raw materials to the adhesive application plate through a feeding pipe. A rotating rod is then activated to move the adhesive application plate to apply adhesive to the plastic body. The support platform is then reset, and a control cylinder moves the pressing plate downwards, allowing the leather fixed to the upper mold by the fixing posts to adhere to the plastic body. The pressing plate is then further pressed down, causing it to push the control plate to slide, thereby rotating two control rods to retract the two fixing posts into the upper mold. This allows the leather to detach from the upper mold. Finally, a folding device folds the leather edges, facilitating leather covering and improving work efficiency.
