Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of laminating, in particular to a water glue laminating method for a UV low-penetrability material.
[ background of the invention ]
The water gel belongs to UV (Ultraviolet ray) illumination series glue, and is cured through UV irradiation, so that the two objects are bonded. The water glue laminating technology is widely used for various electronic products such as mobile phones and tablet computers.
The pre-curing energy range of the existing water glue laminating machine is 200J/cm2～300J/cm2. However, when the UV low-permeability material is attached, due to the low UV transmittance of the material, the pre-curing energy is lower than 200J/cm2. After the laminating, take place the condition that the low penetrability material of UV slided for by the laminating piece easily, lead to appearing laminating off normal, bubble bounce-back scheduling problem.
Therefore, there is a need to develop a method for applying a UV low-permeability material to a substrate with a water-based adhesive to solve the above problems.
[ summary of the invention ]
The invention aims to provide a glue laminating method of a UV low-penetrability material, which can realize glue laminating of the UV low-penetrability material and has a good laminating effect.
In order to achieve the purpose, the invention adopts the following technical scheme:
a water glue laminating method of a UV low-penetrability material comprises the following steps:
s1: attaching a double-sided foam adhesive tape to the edge of the attaching surface of the product to be attached;
s2: coating water gel on the binding surface of a product to be bound according to a pre-designed fishbone pattern, wherein the water gel cannot exceed the range of the double-sided foam adhesive tape, and the thickness of the water gel is slightly smaller than that of the double-sided foam adhesive tape;
s3: pressing and pasting a UV low-penetrability material;
s4: performing side curing on the side surface of the attached product;
s5: and curing the front surface of the attached product.
As a further improvement of the present invention, in S1, the double-sided foam tape is transparent.
As a further improvement of the present invention, in S3, after the UV low-penetration material is pressed, whether the bonding position of the UV low-penetration material is correct is checked; if not, correction processing is carried out.
As a further improvement of the invention, before the UV low-permeability material is pressed, the UV transmittance of the UV low-permeability material is measured by using a UV measuring instrument.
As a further improvement of the present invention, in S5, the front curing time of the attached product is adjusted according to the measured UV transmittance.
The invention has the beneficial effects that: the double-sided foam adhesive tape is utilized to pre-fix the UV low-penetrability material before the UV low-penetrability material is contacted with the water adhesive, so that the condition of lamination deviation in the lamination process is effectively avoided; after pressing the low penetrability material of subsides UV, carry out the side solidification to the side of laminating back product earlier, solidify the front of laminating back product again to realized the laminating of the low penetrability material of UV, the laminating effect is better.
[ detailed description ] embodiments
The technical solution of the present invention is further explained by the following embodiments.
A water glue laminating method of a UV low-penetrability material comprises the following steps:
s1: attaching a double-sided foam adhesive tape to the edge of the attaching surface of the product to be attached;
s2: coating water gel on the binding surface of a product to be bound according to a pre-designed fishbone pattern, wherein the water gel cannot exceed the range of the double-sided foam adhesive tape, and the thickness of the water gel is slightly smaller than that of the double-sided foam adhesive tape;
s3: pressing and pasting a UV low-penetrability material;
s4: performing side curing on the side surface of the attached product;
s5: and curing the front surface of the attached product.
Wherein, the double-sided foam tape adopted in S1 is transparent. In S3, when pressing the low penetrability material of UV, the low penetrability material of UV is pasted with two-sided bubble cotton tape earlier, and then, two-sided bubble cotton tape is compressed, and the low penetrability material of UV contacts the glue. After the UV low-penetrability material is pressed, whether the bonding position of the UV low-penetrability material is correct or not needs to be checked; if not, correction processing is carried out. During inspection, the inspection can be carried out by naked eyes of an operator, and automatic detection equipment such as a CCD camera can also be adopted for inspection.
In order to ensure the UV curing effect and improve the UV curing efficiency, the UV penetration rate of the UV low-penetration material is measured by a UV measuring instrument before the UV low-penetration material is pressed. In S5, the front curing time of the attached product is adjusted according to the measured UV transmittance.
According to the invention, the double-sided foam adhesive tape is firstly utilized to pre-fix the UV low-penetrability material, and then the UV low-penetrability material is contacted with the water adhesive, so that the condition of lamination deviation in the lamination process is effectively avoided. After pasting the low penetrability material of UV in S3, carried out the side solidification earlier, carried out the front solidification again, the leading cause lies in, the UV penetration rate of the low penetrability material of UV is low, and curing time is longer, in order to prevent curing process water glue overflow laminating position, will bond all around through the side solidification earlier and seal, carries out the front solidification again to the laminating effect of product has been guaranteed.
The technical principles of the present invention have been described above in connection with specific embodiments, which are intended to explain the principles of the present invention and should not be construed as limiting the scope of the present invention in any way. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
