擠壓狹縫式模具塗佈(extrusion slot die coating)是當前液晶顯示器產業製程中於玻璃面板上塗佈的一種新穎有效塗佈方式。此塗佈方式受到青睞,主要是由於其具有塗液使用率高,產率佳,且產品大型化的塗佈亦不受限制之優點,因此目前各大設備廠無不朝向擠壓式塗佈技術為研發之方向。
Extrusion slot die coating technology has been widely used in LCD industry as an effective manufacturing process for coating in the grass. The advantage of this coating process includes the utility rate of coating liquid is rather high, production efficiency is pretty good, and there is no limitation in the size of coating.
While this technology has been adopted by most manufacturers, yet there is still room for better improvement especially in the respect of automatically control of the accuracy of precision and parallel of coating equipment. In the traditional mechanism, in order to obtain the effect of evenly thickness of coating film, a clearance between the coating liquid outlet within the range of its width and the coating board is required during the process of extrusion slot die coating. In other words, this process requires a high accuracy of parallel.
However, the current technology still suffers from manually readjusting the accuracy of parallel. Since the manual procedure is labor intensive and time consuming which leads to the downgrade of efficiency. This research therefore intends to design and develop a six-linked mechanism to overcome the above-mentioned drawbacks of the traditional mechanism.
As the mechanism has been constructed and operated, it has been demonstrated that it indeed reaches the expected result of simultaneously adjust the parallel and height between die and coating board. Furthermore, when operating at a special angle, this mechanism also provides a new function of enhancing the resolution of the vertical direction.
