The optimized flow is used for printing oil when the large plates in the previous working procedure are not bound into small particles, so that the production efficiency is improved, and the cost is reduced. Meanwhile, the large plate is aligned with the mark by using a CCD lens, so that the alignment precision is improved.
Description
Technical Field
The invention relates to the technical field of LCD processing, in particular to an ink screen printing process for an LCD glass plate.
Background
Some current LCD products require printing of patterns with ink on the glass surface.
The current process is as follows: after the production of the former process, boundary piece, liquid crystal filling, three times of cleaning, visual inspection, printing ink printing, testing and polarizer pasting. In the process flow, because the small grains (glass plates) are formed after the boundary plates, the printing ink also needs small grains, and the small grains have the defects that: the efficiency is low, and the labor cost is high; the ink placement deviation from grain to grain is large because small-grain LCD positioning is by LCD edge and the glass edge is affected by the border piece.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide an ink screen printing process for an LCD glass plate, which is directed to the above-mentioned deficiencies of the prior art.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: an ink screen printing process for an LCD glass plate comprises the following steps: after the production of the previous process is finished, printing ink, bonding a wafer, filling liquid crystal, cleaning, attaching a polarizer, detecting and testing; wherein the ink printing process comprises the following steps: printing an ink layer on the surface of the glass plate, printing a washable protective layer on the surface of the ink layer, wherein the thickness of the protective layer is 10-30 mu m, and washing the protective layer by soaking 5-20 mins in an ultrasonic water tank of the washing process. The ink layer is binary reaction type ink, and the hardness after curing is 5-6H. In the interface process, the CCD lens is aligned with the mark on the glass plate.
The invention has the beneficial effects that: the optimized flow is used for printing oil when the large plates in the previous working procedure are not bound into small particles, so that the production efficiency is improved, and the cost is reduced. Meanwhile, the large plate is aligned with the mark by using a CCD lens, so that the alignment precision is improved.
Drawings
FIG. 1 is a schematic structural diagram of the ink of the present invention after printing to before interface.
In the figure, 1, a glass plate; 2. an ink layer; and a protective layer.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in FIG. 1, the ink screen printing process for LCD glass plate comprises the following steps: after the production of the previous procedure is finished, printing ink, laminating, filling liquid crystal, cleaning, adhering a polaroid, carrying out visual inspection and testing. The former process is to finish the jointing of two glass plates (large plates) and a sealing frame. The interface process refers to cutting a glass plate (large plate) into small-sized glass plates. The liquid crystal is poured into the gap of the sealing frame between the two glass plates. The cleaning process refers to cleaning the glass plate with ultrasonic water solution to eliminate the impurity. The step of attaching the polaroid refers to attaching the polaroid on the surfaces of the two glass plates. The visual inspection process refers to the detection of the appearance by visual inspection. The testing process refers to the detection of the formed LCD module by the detection tool.
But because there are some new problems in the process after the change:
1) scraping the ink. The ink layer may be scratched because a lot of glass debris may be generated during the interfacial process.
2) The ink layer may be damaged by the solution and ultrasonic waves in the three cleaning processes.
In order to solve the above technical problems, the following technical solutions are provided: the printing ink process comprises the following steps: printing an ink layer on the surface of the glass plate, printing a washable protective layer on the surface of the ink layer, wherein the thickness of the protective layer is 10-30 mu m, and washing the protective layer with 5-20 mins of soaking water in an ultrasonic water tank of the washing process; the protective layer is made of water-based acrylic resin. The ink layer is binary reaction type ink, the hardness is improved to 5-6H from original 2-3H, 100% OK is tested by adhesion Baige method, and the alcohol resistance and the cleaning agent resistance are more than 30 mins. In the interface process, the CCD lens is aligned with the mark on the glass plate. After the new process is adopted, the screen printing efficiency is improved, and the cost is reduced. The current small-sized screen printing is about 250pcs/Hrs, and the screen printing efficiency of the large-sized plate can be improved to 8K/Hrs. The screen printing precision can reach +/-0.1 mm.
The above examples are intended to illustrate rather than to limit the invention, and all equivalent changes and modifications made by the methods described in the claims of the present invention are intended to be included within the scope of the present invention.
