A glue supply device for disc production

Abstract

The invention discloses a glue supplying device for the production of optical discs, which comprises a bracket, a disc positioning device is installed on the top of the bracket, a centrifugal device connected with the disc positioning device is installed on the bottom of the bracket, the optical disc A height adjustment device connected to the centrifugal device is installed on the bracket outside the positioning device, a gluing device is installed on the height adjustment device, a UV lamp is installed on the height adjustment device, and the CD positioning device includes A first fixing base, the first fixing base is fixedly connected to the middle part of the top of the bracket. In the present invention, gluing is divided into two steps. In the first step, gluing is applied when rotating at a low speed. The height of the UV lamp is relatively high, and the irradiation intensity is low, which is not only beneficial to the adhesion of glue on the disc, but also prevents the glue from being glued due to too high irradiation intensity. Curing, the second step is to rotate at high speed to get rid of excess glue, the glue on the disc will gradually become flat and uniform, the height of the UV lamp is low, and the irradiation intensity is high, which is conducive to the rapid curing of the glue.

Description

technical field [0001] The invention relates to the technical field of optical disc production, in particular to a glue supply device for optical disc production. Background technique [0002] At present, the development of storage discs has further promoted the new reform of the disc format. Among them, the single-disc 1TB long-life optical disc with double-beam super-resolution abandons the traditional 0.6mm disc base + 0.6mm cover layer process during production, and adopts the latest 1.1mm disc base + 0.1mm cover layer production process, but This process puts forward relatively high requirements for the glue covering layer of 0.1mm, especially for the uniformity and flatness of the glue covering layer. Usually, the spraying glue covering layer generally adopts the UV spin-coating glue process. The adopted equipment has simple structure and low cost, and is widely used in this field. [0003] For example, Chinese Patent Publication No. CN201758000U discloses a Blu-ray ...

Problems solved by technology

[0004] The Blu-ray disc gluing device is used in this way: the glue is sizing on the disc through the glue supply system, and then the excess glue is thrown off by centrifugal rotation on one side, and the other side is irradiated by UV light to make the glue cure quickly, but there will be the following Defect: When spraying glue on the disc, at this time the disc rotates at a high speed, it is not easy for the glue to attach to the disc quickly, and secondly, the UV lamp is controlled by the UV lamp control system. Although the intensity of the irradiation can be adjusted, it will increase the failure rate and increase cost
