Back adhesive surface joint method and joint apparatus thereof

Abstract

The invention relates to an attaching method for a back-adhesive skin and an attaching device thereof, in particular to an attaching method for the back-adhesive skin internally arranged in a vehicle door panel for avoiding smearing equipment. The attaching method comprises the steps of preparing materials, pressing the skin in a lower die, adsorbing a molding component to an upper die, pressing in, die unloading of finished products, etc. The coating of the vehicle door panel skin is arranged to face the molding component, so that the pollution of the equipment or the molding component caused by the adhesive can be avoided. Furthermore, the method and the device have the advantages of greatly enhancing the attaching binding force and stability, improving the attaching speed and strengthening the competition and economic benefits of the product.

Description

technical field [0001] The invention relates to a skin lamination technology for automobile interior molded parts, in particular to a method and a device for making an adhesive skin lamination that can improve the lamination efficiency of an automobile inner door panel and the skin. Background technique [0002] General auto parts are mainly made of metal and plastic materials, corresponding to the surface of the components inside the car's passenger space, such as door side panels, door handrails, center console trim, etc., because most of them are made of plastic materials The molded parts that are injected or molded with metal plates have insufficient aesthetics and poor texture on the surface, and may not be liked by consumers. Therefore, car manufacturers usually stick to the surface of the aforementioned molded parts according to the type of vehicle and the needs of consumers. A decorative skin, such as leather or velvet, to enhance the beauty and texture of the vehicl...

AI Technical Summary

Problems solved by technology

However, in actual operation, since the adhesive is applied on the adhesive surface with the skin facing downward, it may drip downward after it is heated and softened, contaminating the surrounding machines and molded parts, causing inconvenience in subsequent processing and requiring frequent shutdowns to clean up

[0004] Furthermore, whether the skin is leather or velvet, it is a soft and flexible material. When it is clamped on the upper mold, the middle part is easy to sag due to its own weight and gravity, which affects the smoothness of the lamination. If a good positioning is not obtained before pressing, it is easy to shake due to the vibration of the machine, causing troubles in pasting. Regardless of the above reasons, it will affect the production efficiency and bonding quality of the skin bonding.

[0005] Therefore, the present inventor has been engaged in research and development and manufacturing experience in related industries for many years, and has made in-depth discussions on the problems faced when the skins of the aforementioned conventional molded parts are attached, and actively seeks solutions. After long-term efforts in research and development, Finally successfully developed a adhesive skin bonding method and its bonding device to overcome the existing problems of skin bonding efficiency and easy to dirty the surrounding environment
