(1) dispensing dam enclosing glue on a glass cover plate of the curved 3D touch screen or the display screen to form a glue frame, wherein the height of the dam enclosing glue is higher than the lower surface of a display module of the 3D touch screen or the display screen;
(2) dispensing surface glue in the glue frame;
(3) pasting the display module on the surface adhesive;
(4) curing;
(5) and wiping off uncured dam adhesive.
Further, the curing catalyst is selected from a thermosetting type, so that more operation time is obtained; the surface glue is pre-cured before the display module is pasted on the surface glue.
Further, the viscosity of the surface glue is adjusted to be between 1000-2000 mPa.s, the lower the viscosity of the glue is, the better leveling effect can be obtained after the surface glue is applied, and due to the fact that the pre-curing can be carried out before the display module is attached to the surface glue, the surface glue can be well leveled after being applied with the leveling, and the adhesion leveling of the display module can be fully guaranteed.
Furthermore, the viscosity of the A-type adhesive of the box dam adhesive is adjusted to 5000-10000 mpa.s, so that the adhesive dispensing operation is facilitated, and the box dam adhesive has good formability and thixotropy after the adhesive dispensing.
Further, the surface glue and the dam glue adopt the same glue system.
By adopting the technical scheme, the A-type glue in the surface glue AB is used as the dam enclosing glue, the curing agent B glue is not added in the A-type glue, the A-type glue cannot be cured in high temperature and conventional environments, the thixotropy is strong, the A-type glue and the surface glue are the same system glue, the mutual reaction cannot occur, and the appearance effect and the curing effect are not influenced; after the surface adhesive is cured, the box dam adhesive is still in an initial state of adhesive dispensing, has good thixotropy and formability, does not overflow the adhesive, and is easy to realize the fitting of the complex curved surface touch screen.

Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Reference is made to the accompanying drawings. The glass cover plate 1 of the 3D touch screen of the mobile terminal is of a curved surface 3D structure.
The method has the advantages that the dam adhesive and the face adhesive are not required to maintain high-precision flatness, and the curved surface 3D touch screen is bonded with good manufacturability.
Wherein, the glue B and the glue A adopt the same glue system, and are combined into water glue. The selection range of AB type water gel comprises: the two-component glue has the characteristics of thermal curing or UV curing. But the manufacturability of the thermosetting glue adopted in the process is better, and a reasonable pre-curing effect can be obtained by controlling the pre-curing time and temperature, so that the laminating is more facilitated; the process conditions are easier to achieve when fully cured. Such as: a silicone-based thermosetting two-component optical glue.
The attaching process is as follows: firstly, dispensing dam adhesive 2 on a curved glass cover plate 1, wherein the height of the dam adhesive 2 is only required to be higher than the lower surface of a display module 4 of a 3D touch screen, and the process has no special requirement on the smoothness of the dam adhesive; secondly, a dispensing machine is used for dispensing the calculated amount of the surface glue into the dam glue 2 for dispensing the surface glue 3, and a dispensing platform must ensure levelness so as to prevent the surface glue from being uneven in thickness; thirdly, placing the dough into an oven for precuring to ensure that the precured dough gum is in the state of jelly, and the conditions are as follows: the temperature is 40-50 ℃, the time is 20-30 min, the pre-curing aims to form the surface glue, the laminating operation is convenient, and the laminating after the pre-curing is not needed to be carried out in a vacuum environment and can be carried out in the atmosphere; fourthly, attaching the display module 4 to the surface glue 3 by using a jig or equipment to attach the display module 4 to the glass cover plate; and fifthly, placing the product into a high-pressure defoaming machine for defoaming, wherein the defoaming conditions are as follows: the pressure is 0.3Mpa, and the time is 10 minutes; sixthly, putting the mixture into an oven for complete curing, wherein the curing temperature is 40-60 ℃, and the curing time is 20-30 min; and seventhly, wiping off the uncured frame glue by using a dust-free cloth. All the procedures are completed.
Due to the strong thixotropy of the A-type adhesive dam glue, glue is not needed to be applied according to the shape of a 3D touch screen when the dam is made, the process is simple, high-precision equipment is not needed, and glue overflow is avoided.
The above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should understand that they can make various changes, modifications and substitutions within the scope of the present invention.
