Abstract
The invention discloses a damming type adhesive dispensing method which comprises the following steps of: S1, determining the area of a to-be-coated adhesive layer, and a specific position of the adhesive layer; S2, setting position parameters of damming adhesive; S3, coating a ring of damming adhesive on protective cover plate glass or a touch screen according to preset position parameters; S4, coating liquid optical adhesive; S5, pre-curing the protective cover plate glass or the touch screen which is coated with the liquid optical adhesive; S6, fitting the pre-cured protective cover plate glass or the pre-cured touch screen to a liquid crystal display module; and S7, carrying out appearance checking, thereby completing fitting. According to the damming type adhesive dispensing method disclosed by the invention, a ring of damming adhesive is firstly coated on the edge of an area which needs to coat liquid optical adhesive by adopting adhesive with relatively high viscosity, i.e., liquid optical adhesive for coating in follow-up processes is dammed, so that the problem that thickness of the edge of the adhesive layer is uneven due to the fact that liquid optical adhesive is diffused outwards is solved, and therefore, flatness of the adhesive layer is guaranteed, and the fitting yield is increased.
Description
Technical field
The present invention relates to optics entirely to fit field, particularly relate to one and build a dam formula dispensing method.
Background technology
As the display to electronic equipment for consumption for the consumer requires to improve constantly, the application of the full coating technique of optics
More and more extensive, the new product of some notebook brands such as Dell and association more than 80% all have employed full laminating skill at present
Art, makes screen seem more penetrating, enhances the optics display effect of screen.
At present, when cover sheet glass or touch-screen are fitted with liquid crystal display module, tool point glue shape is mostly passed through
Become fixing area, then, carry out colloid curing process, make colloid solidify, finally fit.But, due to the stream of glue
Dynamic property is relatively strong, and during for dispensing glue, the edge of glue-line easily causes the edge of glue-line in uneven thickness to external diffusion, thus leads
Producing layering bubble after causing edge laminating, its ratio is up to 10-15%, have impact on the yield of laminating largely.
Content of the invention
Formula (DAM) dispensing method it is desirable to provide one is built a dam, needs the optical cement of coating in advance operation below
Water builds " dykes and dams ", prevents the edge of more liquid glue from causing the irregular situation of edge glue-line because of flowing.
For reaching above-mentioned purpose, the technical solution used in the present invention specifically comprises the steps of：
S1, according to the laminating size between cover sheet glass or touch-screen and liquid crystal display module, determine and need coating
Glue-line area and the particular location of glue-line；
S2, the location parameter setting glue of building a dam；
S3, on cover sheet glass or touch-screen, put a circle according to location parameter set in advance build a dam glue；
S4, there is coating fluid bulk optics glue on the cover sheet glass of glue of building a dam or touch-screen at point；
S5, cover sheet glass or the touch-screen of coated optics of liquids glue are carried out precuring；
S6, cover sheet glass or the touch-screen through precuring is fitted with liquid crystal display module；
S7, visual examination, complete laminating.
Further, described glue of building a dam is thermosetting cement, and viscosity is 400000mPa s, and density is 0.98g/cm3.
Further, the internal diameter of the needle head of adhesive dispenser using in described step S3 is 0.3-0.5mm, the rate travel of syringe needle
For 90mm/s.
Further, in described step S5, the device of precuring is baking box, and the temperature of precuring is 60-80 DEG C.
Compared with prior art, the present invention has the advantages that：
The formula dispensing method of building a dam that the present invention provides, is coated with liquid light initially with the higher glue of viscosity required
A circle dam glue is first put at the scope edge learning glue, is equivalent to, to the optics of liquids glue sticking chip of the coating of operation below, solve liquid light
Learn glue and cause the edge of glue-line problem in uneven thickness to external diffusion, thus ensure the planarization of glue-line, improve the good of laminating
Rate.

Compared with prior art, the present invention has the advantages that：
The formula dispensing method of building a dam that the present invention provides, is coated with liquid light initially with the higher glue of viscosity required
A circle dam glue is first put at the scope edge learning glue, is equivalent to, to the optics of liquids glue sticking chip of the coating of operation below, solve liquid light
Learn glue and cause the edge of glue-line problem in uneven thickness to external diffusion, thus ensure the planarization of glue-line, improve the good of laminating
Rate.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
