Glue sprayed coating attaching method and attaching device

Abstract

The invention refers to a coat laminating method for spray adhesives and a laminating device thereof, in particular to a coat laminating method for spray adhesives and a mechanism thereof that protect tools from pollution. The laminating method comprises preparing feed, spraying adhesives on top surface of the coat, heating and softening, pressing the coat into a lower module, absorbing a molding part at an upper module, laminating, demoulding a finished product and other steps. A rubber coating surface of the coat is upwards to prevent the tools or the molding part from being polluted by the softened sticking agent. Furthermore, binding capacity and steadiness of the laminating can be greatly improved and the laminating velocity can also be improved. The method has the advantages of improving competitive strength 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 glue-spray skin lamination method and a device thereof which can improve the lamination efficiency of automobile inner door panels and skins. Background technique [0002] Generally, auto parts are mainly made of metal and plastic materials. The interior components of the car’s passenger space, such as door side panels, door armrests, center console trim, etc., are mostly made of plastic materials. Formed parts molded from metal plates have insufficient surface aesthetics and poor texture, and are not favored by consumers. Therefore, car manufacturers usually paste a decorative skin on the surface of the above-mentioned formed parts according to the type of vehicle and the needs of consumers. Such as leather or velvet, etc., to enhance the beauty and texture of the vehicle interior. [0003] In the past, when laminating the skin, the laminati...

Problems solved by technology

However, in actual operation, since the glue is coated on the lower surface of the epidermis, it may drip downward after heating and softening, which will contaminate the surrounding machines and molded parts, causing inconvenience in subsequent processing, and frequent shutdowns for cleaning

[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. It is easy to shake due to the vibration of the machine, which will cause 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 molded parts are laminated, and actively seeks solutions. After long-term hard research and development, he finally succeeded. Developed a glue-spray skin bonding method and its bonding device to overcome the existing problems of poor skin bonding efficiency and easy contamination of the surrounding environment
