Description
Technical field
The present invention relates to a kind of LCD production method more particularly to a kind of liquid crystal display cassette methods.
Background technique
Existing liquid crystal display box technique is to be printed on two sheet glass using epoxy glue by mode of printing, by pressurizeing,
Heat cure processing is sintered.
Concrete technology flow process are as follows: first by the plate-making of one of sheet glass, silk-screen epoxy glue, preliminary drying；Again by other one piece of glass
The plate-making of glass piece, preliminary drying, is dusted at silk-screened conductive material；Then, then pass through combination, precompressed, heat cure.Specific requirement is:
It needs to carry out preliminary drying after epoxy glue silk-screen is good, be toasted 30 minutes with 90 DEG C；Using silver point technique, by the good conducting resinl material of silk-screen
Glass carries out preliminary drying；It dusts, the glass being baked by printed silver point and in advance carries out sprinkling spacer；Combination pastes two sheet glass
It is combined, i.e., the sheet glass of printed epoxy frame adhesive and printed conductive silver point fits together according to the requirement of design；
Then heat cure neatly overlays the glass combined on hot pressing frame as requested, locks upper cover after folding completely, is put into hot pressing
In oven, in addition 1 atmospheric pressure, carries out high temperature sintering.This process time of heat cure is long, i.e., from room temperature to 100 DEG C to
180 DEG C to 180 DEG C to room temperature, baking time corresponding 60 minutes -120 minutes -90 minutes until drop to 50 degree hereinafter, from heating
Terminate to need 4.5 hours to constant temperature, drop to 50 degree or less and need 4 hours, the time of occupancy is long, and energy consumption is high.
The defect of the prior art is: baking temperature is high, the time is long, so energy consumption is high, low efficiency.
A kind of liquid crystal display cassette method high-efficient, low energy consumption how can be just found, is that those skilled in the art compel
Be essential technical problems to be solved.
Summary of the invention
It is an object of the invention in view of the above-mentioned problems of the prior art, providing a kind of liquid high-efficient, low energy consumption
Crystal display screen cassette method.
To achieve the goals above, liquid crystal display cassette method of the invention includes the following steps:
(1) sheet glass is prepared, by the plate-making of one of sheet glass, the modified UV epoxy glue of silk-screen；Other one block of sheet glass is made a plate,
Silk-screened conductive material, dusts at preliminary drying；
(2) it combines, i.e., together by two panels glass gluing；
(3) precompressed；
(4) UV solidifies；
(5) hot plate cure.
Preferably, UV curing schedule, using UV solidification platform UV solidification.
Preferably, the UV curing time is 8-10 seconds.
Preferably, hot plate cure step, using hot plate cure machine hot plate cure.
Preferably, the hot plate cure, solidification temperature from room temperature be progressively heated at 100 degree it is gradually air-cooled to room temperature again,
Curing time is 3-5 minutes.
Using method of the invention, after frame adhesive is changed to modified UV epoxy glue by original epoxy glue, by former heat cure
It is hot plate curing to be changed to VU solidification, UV solidification only needs that solidification can be completed within 8-10 seconds, reuses hot plate and is heated to 100 degree of 3-
Solidification effect can be fully achieved within 5 minutes, to overcome the defect of the prior art, improve efficiency, reduce energy consumption.
Further, since curing mode, which has changed UV by curing oven, solidifies hot plate curing machine, automated job may be implemented,
Working efficiency may further thus be improved.
Through testing, using method of the invention, for production efficiency than improving 40% originally, product hands over time phase to improve
50%, the electricity charge reduce by 20%, and tool fixture can save 500,000, and production yield, which integrally improves 3% cost of labor, reduces 1%.
Specific embodiment
Illustrate technical solution of the present invention With reference to embodiment.
Liquid crystal display cassette method of the invention includes the following steps:
(1) sheet glass is prepared, by the plate-making of one of sheet glass, the modified UV epoxy glue of silk-screen；Other one block of sheet glass is made a plate,
Silk-screened conductive material, dusts at preliminary drying, this is the prior art.
(2) it combines, i.e., together by two panels glass gluing.This is the prior art.
(3) precompressed.This is the prior art.
(4) UV solidifies.Using UV solidification platform UV irradiation solidification.UV curing time is 8-10 seconds.
(5) hot plate cure.Using hot plate cure machine hot plate cure.Solidification temperature from room temperature be progressively heated at 100 degree again by
Gradually air-cooled to room temperature, curing time is 3-5 minutes.
Claims (5)
1. a kind of liquid crystal display cassette method, it is characterised in that include the following steps:
(1) sheet glass is prepared, by the plate-making of one of sheet glass, the modified UV epoxy glue of silk-screen；Other one block of sheet glass is made a plate,
