Frame glasses and processing method thereof

Abstract

The invention relates to a processing method of frame glasses. The frame glasses comprise a glasses frame, glasses legs, first hinges and second hinges, wherein the glasses frame and the glasses legs are made of plastics, and the first hinges and the second hinges are made of metal. The method comprises the following steps: S1) heating the first hinges and the second hinges respectively to a first critical temperature and a second critical temperature, wherein the glasses frame and the glasses legs are melted at the first critical temperature and the second critical temperature respectively; S2) pressing the heated first hinges and the heated second hinges into corresponding places of the glasses frame and the glasses legs via cylinder pressure; S3) cooling the heated first hinges and theheated second hinges to connect with the glasses frame and the glasses legs respectively; and S4) connecting the first hinges with the second hinges. In the glasses frame and the processing method thereof provided by the technical scheme of the invention, a seamless hot-pressing connection is adopted between the metal hinges and the plastic glasses frame or between the metal hinges and the plastic glasses legs. The frame glasses are characterized by smooth and beautiful shaping, and the connection is tightened and the metal hinges are not easy to fall off. Meanwhile, an exterior plane of the hinge parts becomes a decoration for pile-head parts in the glasses legs and glasses frame, and the seamless effect at the periphery of the decoration is better than that of similar products in the industry.

Description

technical field [0001] The invention relates to spectacles, in particular to frame spectacles using seamless welding technology on temples and frames and a processing method thereof. Background technique [0002] Metal parts need to be used for hinges between the temples of the frame glasses and the picture frame, and a fixed connection between the metal parts and the plastics of the temples and / or the picture frame is required. In the prior art, milling technology is generally used, and screws and rivets are used to fix the metal part and the plastic. However, there is usually a certain gap between the temples and the frame of the frame glasses of the above-mentioned prior art, so the connection is not very firm, and it is easy to fall off after a long time of use. Contents of the invention [0003] The object of the present invention is to provide a kind of frame glasses and its processing method, in order to solve the above-mentioned problems existing in the prior art....
