Description

A kind of touch screen point glue laminating method
Technical field
The present invention relates to applying method, particularly a kind of touch screen point glue laminating method.
Background technology
In current normally used some glue laminating method, because the location of upper and lower substrate is inaccurate, have impact on the laminating quality of product, and production efficiency is lower.In actual production, use solid state optics glue or liquid UV-cure optical glue by upper and lower substrate bonding and fit together, the shortcoming of solid state optics glue is used to be can there is a large amount of bubbles between the upper and lower base plate that fits together, utilize some defoaming methods it all can not be taken off, cause the yields of producing to be subject to great impact, too increase the production cost of product; Although and adopt liquid UV-cure optical glue to decrease the generation of bubble, because the restriction of operating condition can not be avoided completely.Existing upper and lower baseplate-laminating mode is " first irradiation ultraviolet radiation after laminating ", due on put tool platform surface and may have overcover, can not ensure that the glue of upper substrate is subject to ultraviolet irradiation completely, thus affect the solidification of glue, and existing ultraviolet irradiation time is shorter, the hardening time of glue is longer, affects production efficiency.
Summary of the invention
The object of the invention is the positioning precision improving upper substrate and subtegulum, the laminating degree of accuracy of substrate and subtegulum in control, reduce the generation of bubble, improve the yields of producing, shorten the hardening time of ultraviolet glue, enhance productivity.For this reason, the present invention proposes a kind of touch screen point glue laminating method.
Technical scheme provided by the invention is:
A kind of touch screen point glue laminating method, comprising:

Described underlying tool platform transferred to by step 4, the upper substrate of having fitted, initial position got back to by described underlying tool platform, put tool platform on simultaneously described upwards to turn over turnback and get back to original state, the substrate of having fitted is pushed into next station by described horizontal pusher under the second power drive;
Wherein, described upper substrate rest area and described subtegulum rest area are all set to photosensitive platform, and be connected with indicating device, when the contact area of described upper substrate and described upper substrate rest area is greater than 90%, upper substrate blocked be irradiated to substrate rest area more than 90% light source, indicating device screen display is that upper substrate placement position is correct, otherwise indicating device screen display for needs reappose upper substrate, the laying method of subtegulum is identical with the laying method of upper substrate.
Preferably, in described touch screen point glue laminating method, tool platform and underlying tool platform 2-4mm are all put in described upper substrate rest area and subtegulum rest area on described.
Preferably, in described touch screen point glue laminating method, described underlying tool platform be moved upwards up to described on put tool platform the position speeds control that carries out substrate laminating be 150-200mm/s, when described upper substrate will be touched, speed reduces to 0.01-0.05mm/s, in laminating process, speeds control is 5-10mm/s.
Preferably, in described touch screen point glue laminating method, two described adhesive dispensing devices carry out a glue to described upper substrate simultaneously, and when described two underlying tool platforms move up and down, plane of motion puts the plane keeping parallelism at tool platform place all the time with on two.
Preferably, in described touch screen point glue laminating method, after the some glue of described upper substrate completes, ultraviolet lamp is used to irradiate glue application region 1-2min.
Preferably, in described touch screen point glue laminating method, the glue that some glue uses is delayed ultraviolet glue hardening time, after Ultraviolet radiation 5-40min, complete solidification.
Preferably, in described touch screen point glue laminating method, some glue mode is for dripping or mode of printing.
Touch screen point glue laminating method of the present invention, described upper substrate rest area and subtegulum rest area all slightly can raise up under power drive and be beneficial to the placement of substrate and subtegulum, the setting of photosensitive platform accurately can show the contact area of described upper substrate and described upper substrate rest area and described subtegulum and described subtegulum rest area, ensure that effective laminating of substrate and subtegulum.On described underlying tool platform moves up and carries out under the second power drive effect during the laminating of substrate and subtegulum, control translational speed fast more first quick and back slow, excessive velocities avoids subtegulum when being about to fit with upper substrate owing to can not get rid of the gas of UV glue water surface completely, make to produce bubble in ultraviolet glue, affect the quality of touch screen; The last pick up speed again of laminating process improves production efficiency while guarantee laminating quality.This method changes the laminating type of existing " first irradiation ultraviolet radiation after laminating " mode of into " fitting after first irradiation ultraviolet radiation ", and extend the ultraviolet irradiation time, shorten the hardening time of liquid ultraviolet glue, liquid ultraviolet glue can obtain ultraviolet comprehensive irradiation thus even, whole curing molding, effectively improve and block due to upper substrate the problem that the liquid ultraviolet glue that causes ultraviolet to be irradiated to cannot solidify, improve the quality of product and the efficiency of production.
