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 the present normally used some glue laminating method, because the location of upper and lower substrate is inaccurate, affected the applying quality of product, and production efficiency is lower.In actual production, use solid state optics glue or liquid ultraviolet curing optical glue with upper and lower substrate bonding and fit together, using the shortcoming of solid state optics glue is can have 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, the yields that causes producing is subject to great impact, has also increased the production cost of product; Although and adopt liquid ultraviolet curing optical glue to reduce the generation of bubble, because the restriction of operating condition can not be avoided fully.Existing upper and lower baseplate-laminating mode is " irradiation ultraviolet radiation after fitting first ", since on put the tool platform surface and may have overcover, the glue that can not guarantee upper substrate is subject to ultraviolet irradiation fully, thereby affect the curing of glue, and existing ultraviolet irradiation time is shorter, the hardening time of glue is longer, affects production efficiency.
Summary of the invention
The objective of the invention is to improve the positioning accuracy of upper substrate and subtegulum, the applying degree of accuracy of substrate and subtegulum in the control reduces the generation of bubble, improves the yields of producing, and shortens the hardening time of ultraviolet glue, enhances 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 comprises:
Step 1, on put the tool platform upper substrate rest area under the driving of the first motor, slightly raise up, described upper substrate is placed on described upper substrate rest area, if the contact area of upper substrate and described upper substrate rest area is greater than 90%, then with the fixing described upper substrate of fixture, otherwise reappose substrate, point glue equipment is moved to a glue position in the first power drive, the rotation platform of regulating described point glue equipment makes adhesive dispensing device carry out a glue over against the glue application region of upper substrate, uses ultraviolet glue to upper substrate to shine;
Step 2, put the tool platform on described and under the driving of servomotor, turn over turnback downwards, regulate the flip angle that the tool platform is put in the rotating speed control of described servomotor on described;
Step 3, the subtegulum rest area of underlying tool platform slightly raises up under the driving of the second motor, described subtegulum is placed on described subtegulum rest area, if the contact area of subtegulum and described subtegulum rest area is greater than 90%, then with the fixing described subtegulum of fixture, otherwise reappose subtegulum, described underlying tool platform is moved upwards up to the applying position under the second power drive, in this moving process, the control translational speed is fast more first quick and back slow, finely tune simultaneously the rotating speed of putting the servomotor of tool platform on described, control described upper substrate and subtegulum and position applying;
Step 4, the upper substrate of finishing of fitting are transferred to described underlying tool platform, described underlying tool platform is got back to initial position, put the tool platform on simultaneously described and upwards turn over turnback and get back to original state, the substrate that described horizontal pusher is finished applying under the second power drive is pushed into next station;
Wherein, described upper substrate rest area and described subtegulum rest area all are set to the sensitization platform, and be connected with indicating device, when the contact area of described upper substrate and described upper substrate rest area greater than 90% the time, upper substrate has blocked the light source more than 90% that shines the substrate rest area, the indicating device screen display is that upper substrate placement location is correct, otherwise the indicating device screen display be for need to reappose substrate, and the laying method of subtegulum is identical with the laying method of upper substrate.
Preferably, in the described touch screen point glue laminating method, described upper substrate rest area and subtegulum rest area all are higher than puts tool platform and underlying tool platform 2-4mm on described.
Preferably, in the described touch screen point glue laminating method, described underlying tool platform is moved upwards up to the position of putting the tool platform on described to carry out the speed that substrate fits and is controlled to be 150-200mm/s, in the time will touching described upper substrate, speed is reduced to 0.01-0.05mm/s, in the applying process, speed is controlled to be 5-10mm/s.
Preferably, in the described touch screen point glue laminating method, described two adhesive dispensing devices carry out a glue to described upper substrate simultaneously, and when described two underlying tool platforms moved up and down, plane of motion was put the plane keeping parallelism at tool platform place all the time with on two.
Preferably, in the described touch screen point glue laminating method, after the some glue of described upper substrate is finished, use ultraviolet lamp irradiation glue application region 1-2min.
Preferably, in the described touch screen point glue laminating method, the ultraviolet glue that the glue that some glue uses lagged behind as hardening time is finished curing behind ultraviolet ray irradiation 5-40min.
Preferably, in the 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 can slightly raise up under power drive and be beneficial to the placement of substrate and subtegulum, the setting of sensitization platform can accurately show the contact area of described upper substrate and described upper substrate rest area and described subtegulum and described subtegulum rest area, has guaranteed effective applying of upper substrate and subtegulum.On described underlying tool platform moves up under the second power drive effect and carries out during the applying of substrate and subtegulum, the control translational speed is fast more first quick and back slow, avoided subtegulum when being about to upper substrate applying, can not get rid of the gas of UV glue water surface fully owing to excessive velocities, make in ultraviolet glue and produce bubble, affect the quality of touch screen; The last again pick up speed of applying process has improved production efficiency when guaranteeing the applying quality.This method changes the laminating type of existing " irradiation ultraviolet radiation after fitting first " into the mode of " fitting behind the first irradiation ultraviolet radiation ", and prolonged the ultraviolet irradiation time, shortened the hardening time of liquid ultraviolet glue, thereby liquid ultraviolet glue can obtain even, the whole curing molding of ultraviolet comprehensive irradiation, effectively improved since upper substrate block the problem that the liquid ultraviolet glue that causes the ultraviolet ray to shine can't solidify, improved the quality of product and the efficient of production.
