One of the key technologies of full-screen, hard-screen special-shaped processing and molding technology has regained attention

Information

  In the full-screen display technology, in order to obtain a smoother rounded corner design effect, the hard-screen special-shaped forming technology is a very important part of it. The time when China began to introduce a large number of rigid display special-shaped processing and molding technologies in the Chinese market can be traced back to the period when China's domestic black-and-white LCDs began to be popularized. Specifically, electronic watches with liquid crystal displays began to flood, and foreign brand companies began to seek differentiated survival in the high-end market, but the production capacity of black and white liquid crystal displays was concentrated in China in the middle and late 1990s.

  I remember that in order to develop LCD screens that could cut octagons, circles, and even holes in the middle, they also searched the entire LCD display supply chain manufacturers. Under the circumstances that cannot be solved in the industry, the scope has also been expanded to the jewelry processing and eyewear processing industries. Grinding machines, sanders, and ultrasonic special-shaped drilling machines have all appeared in the workshop. It is believed that there are still black-and-white LCD manufacturers in the industry. They are still using Beijing's grinding machine factory for processing glasses and high-speed drilling machines for lathes and tool holders to process these irregular-shaped LCD displays.

  Finally, in order to find more suitable glass processing equipment, I also found the craft carving machine used in the advertising industry to process signboards, just because the above description can process "plexiglass" and can also perform curve cutting. After I got it, I found that the process speed of the spindle is too low and it can only cut plastic "plexiglass". It cannot cut real silicon-based glass. In order to use it to cut glass, we have to use various methods to mill The speed of the blade grinding head is mentioned above 3600 rpm. Now the best glass carving machine is actually developed based on the combination of grinding machine, high-speed drilling machine and craft carving machine, plus ultrasonic efficiency assistance.

  The second wave of enthusiasm for the processing of shaped glass processing technology broke out. It was also a period when the technology of glass carving machine was not mature after the capacitive touch screen market came up. In order to improve the processing efficiency of glass cover plates, the industry hoped to introduce shaped glass. The processing and forming machine can profile the glass cover plate at the time of opening to reduce the grinding time of the glass with four rounded corners. However, with the breakthrough of the grinding head technology of the glass engraving machine, after the multi-stage grinding heads with different cutting speed abrasives can be produced on one forming knife at the same time, the processing of shaped glass has become a very simple matter.

  “智能手机保护玻璃盖板的应用,正是由中国企业开始引领全球手机制造业新技术应用的代表。”深圳市远洋翔瑞机械有限公司(以下简称:远洋翔瑞)董事长龚伦勇先生对手机报在线表示,“玻璃CNC精雕机及智能手机保护玻璃盖板加工技术,完全是由中国人研发出来,并被中国产业界持续改进与完善的‘中国技术’。” 远洋翔瑞在3C行业、消费类产品的面板、机壳等快速加工领域,已经有了全自动玻璃精雕设备、智能高光设备等全自动智能制造车间整体解决方案。

  随着智能手机的显示技术进入全面显示时代,业界对于全面屏的异形加工成型技术再次关注起来。其中与柔性OLED显示屏相关的产业链企业,利用在柔性OLED显示屏加工中比较成熟的激光加工成型技术,直接对盖板玻璃和柔性OLED显示屏进行外形成形加工;而传统的硬屏OLED\LCD显示屏相关的产业链企业,则在原来其它如汽车显示器、艺术显示器等特种显示器制造基础上,再次开发出了刀轮式异形玻璃加工成型机;而有玻璃盖板加工技术的厂商,当然再次利用起了CNC玻璃精雕机的玻璃深加工技术,直接用原来的直线玻璃加工成型机开料后,再用CNC玻璃精雕机进行倒圆、切角加工;当然,也有的厂商同时采用了异形玻璃加工成型机和激光玻璃加工成型机两种技术,来实现全面显示屏的异形加工成型。

  不过远洋翔瑞表示,在硬屏OLED\LCD全面显示屏的加工成型加工上,直线玻璃加工成型机+远洋CNC玻璃精雕设备方案,仍时目前行业成本最低的解决方案。远洋翔瑞认为,很多行业企业都有过投资OGS电容式触摸屏的经验,硬屏OLED\LCD全面显示屏的加工成型加工,与OGS电容式触摸屏的外形成型加工,在原理和工艺上都是相通的,加工技术也是完全兼容的。

  远洋翔瑞在与客户沟通时发现,采用其它加工成型方式的硬屏OLED\LCD全面屏加工成型持术,不一定有当年加工OGS电容式触摸屏时,所积累的如何保护硬屏OLED\LCD PIN脚与线路技术,而且有些客户即便是有,也不一定成本可以降到同样水平,能为客户节省更多的成本,获得更高的加工良率和加工质量,从而获得更多的利润。

  而远洋翔瑞在全面屏显示技术领域的布局十分广泛,如配合全面屏显示的3D曲面玻璃盖板和3D玻璃钢化膜方面,远洋就开发了从包括玻璃加工成型、打磨、热弯、精抛等整个工艺流程的设备与技术。“事实上,硬屏OLED\LCD全面显示屏同样可以配合3D曲面玻璃盖板一起使用,同样能得到很好的手机外观设计效果,而远洋翔瑞的客户中,也已经有采用这种组合方式的产品出货。”

  为了更好的展示配合了3D曲面玻璃盖板的全面屏显示技术手机效果,硬屏OLED\LCD全面显示屏的四个角同样需要进行精密加工成型,听筒、摄像头位置可能还要挖空。这些部位的精密加工,远洋翔瑞都为业界给出了十分完善的解决方案。

  硬屏OLED\LCD全面显示屏采购成本要比传统的硬屏OLED\LCD显示屏稍高,加上加工工序增加,每一道工序的良率损失和成本增加,都会最终影响LCD全面显示屏加工厂商的收益。寻求一种成熟技术来稳定良率,降低投资本,加快产品上市时间,也成了行业急需解决的重要课题。

  在目前情况下,远洋翔瑞把成熟加工3D曲面玻璃盖板和3D玻璃钢化膜的异形加工成型技术,作为实现硬屏全面屏完美显示的关键环节之一引入到全面显示屏的外形加工成型工序上,不但大幅度的降低了显示屏加工企业的投资成本,而且也缩短客户产品的上市时间,因此在市场快速推进过程中,重新被行业上、下游重点关注起来,也是理所当然的事。

  COSCO Xiangrui also said that in addition to continuing to provide customers with mature molding and processing technologies such as sapphire, 3D glass, ceramics and other new brittle material structures, metal structures, display devices, etc., it will be used in the field of brittle material mobile phones in the future. Based on the equipment manufacturing industry, research and development of more new types of special materials CNC numerical control equipment, as well as the development of corresponding processing equipment for the emerging new materials of mobile phone structural parts, make COSCO Xiangrui a smart manufacturing of global mobile phone structural parts with Chinese characteristics Solution provider.
