Description
Technical Field
The invention relates to the technical field of dispensing, in particular to an ink-jet printing device.
Background
A key core process in the Flat Panel Display (FPD) industry is optical glue lamination. The optical cement bonding mode generally has two modes, namely solid optical cement bonding and liquid optical cement bonding according to the form of an optical cement supplied material. The liquid optical cement is widely applied to products with the film thickness (namely, the thickness of the optical cement after the optical cement is converted from the liquid state to the solid state) larger than 200 mu m, such as computer displays, vehicle-mounted display modules and the like, and cannot be applied to products with the film thickness smaller than 200 mu m, such as mobile phone display modules, tablet computer display modules and the like. Because the traditional liquid optical glue has a very critical site in the laminating process, the glue coating adopts a single-hole dispensing mode or a slit coating mode, the single-hole dispensing adopts a process of dispensing double-Y-shaped or fishbone-shaped glue on a display panel (panel), and then the Cover Glass (CG) is utilized to press down to apply pressure on the surface of the glue, so that the glue is diffused and spread to the whole panel surface under the action of the pressure. The mode drawback of single-hole dispensing is that the flow of glue is uncontrolled under the action of pressure, and 100% of glue overflows, so that a glue scraping post needs to be added to solve the problem, which not only increases the labor cost, but also increases the risk of product defects, such as secondary damage, e.g., scratches, fragments, dirt, etc., in the glue scraping process. The slit coating adopts that liquid optical glue is sprayed out from a slit, a coating head is driven by a motion control system, scanning is carried out, and finally a surface is formed. Therefore, the end user has to choose a solid optical adhesive bonding process with higher cost to apply to the light and thin module process, such as mobile phone, tablet computer, etc.
Therefore, an important issue to be solved in the industry is to realize a dispensing device with accurate glue spraying position and uniform film thickness in the panel display industry.
