Abstract

The invention relates to a production method of a car sun visor, which is characterized in that: the production method adopts the following technological steps: firstly using a hot-melt adhesive for bonding an iron frame with corrugated paper together; further using a double-sided adhesive tape for adhering foam cotton on two sides of the corrugated paper; utilizing the high-frequency welding wayfor wrapping an inner core material in a PVC surface; utilizing an ultrasonic device for riveting a sleeve; mounting a rotating arm; and forming a finished product after mounting the rotating arm. Theproduction method solves the performance indexes of high cost, unrecoverable property, easy contamination when meeting dust, difficult cleaning of dirt, lightweight and the like of the sun visor assembly, achieves the level 3 of the international leading level, greatly reduces the weight of the sun visor and meets the requirements on the lightweight design of a whole car; materials adopted for the PVC surface, the corrugated paper, the foam cotton and the iron frame are recoverable; and the high-frequency welding and the ultrasonic riveting process do not produce pollution or harmful substances, thereby being in line with the requirements of environment-friendly products.

Description

technical field [0001] The invention relates to a production method of an automobile sun visor. Specifically, the automobile sun visor is used to be installed on the front of the roof of the automobile to play the role of blocking sunlight, and belongs to the technical field of automobile interior decorations. Background technique [0002] Car sun visors are generally installed on the top of the car roof to block sunlight. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as light weight, aesthetics, and low cost of sun visors have become bottlenecks, restricting the development of sun visors. Existing sun visors are usually welded with flannelette and ...
