Method and device for bonding stud onto glass

Abstract

The invention relates to the technical field of glass accessory bonding, in particular to a method and a device for bonding a stud onto glass. The method comprises the following steps of: respectively coating a base coat on the surfaces of the stud and the glass to be bonded; turning on an injection molding machine, setting injection molding parameters, and fixedly embedding the stud in a groove of an injection mold; compressing the surface of the glass to be bonded on the bottom of the injection mold so as to form a closed cavity; starting the injection molding by the injection molding machine, and injecting a plasticized soft resin into the injection mold so that the soft resin is coated on a base of the stud and is firmly bonded by the base coat; and finally removing a pouring gate remained in the stud after de-molding. The invention further provides a bonding device used for carrying out the method. According to the method and the device for bonding a stud onto glass, the injection molding process is simple so that the automatic production can be realized, the production is fast so that the production efficiency can be increased, the bonding strength is high due to the dual function of base coat bonding and PVC (polyvinyl chloride) coating, the development costs of a bonding material and a mold are low so that the production cost is lowered.

Description

Technical field: [0001] The invention relates to the technical field of bonding of glass accessories, in particular to a method for bonding nail posts to glass, and also to a bonding device used for implementing the method. Background technique: [0002] With the development of the global economy, automobiles have become the most important means of transportation for people, and people pay more and more attention to the safety performance of automobiles. Auto glass is an indispensable and important part of the car. The accuracy and reliability of its positioning on the car body will directly affect the reliability of the bonding between the glass and the body sheet metal and the sealing effect of the edge strip. At present, the automotive glass is mainly precisely positioned to the corresponding connection of the body through nail posts to ensure long-lasting reliability. [0003] In the prior art, there are mainly the following three ways of bonding glass accessories such ...

AI Technical Summary

Problems solved by technology

The way of using integral injection molding can only cover the nail post together when the injection molding car is edged. Due to the limitations of equipment and technology, it is difficult to inject the nail post onto the glass separately, and the overall mold design is complicated, the development cost is high, and the injection molding is fast. The side is not easy to clean and the workload is heavy
