Technical Field
The invention relates to the technical field of electronic display, in particular to a wet glue full-lamination process of a cover plate and a display module.
Background
With the advance of the automatic wave of processing, the pad pasting mode is also mostly changed into mechanical pad pasting from manual pad pasting gradually. For a traditional bar phone, a single roller is utilized to roll and paste a protective film on a plane of the phone to realize film pasting, but when a 3D curved screen or a 2.5D screen is pasted, the edge of the protective film cannot be completely pasted with a curved surface of the phone, and the curved surface part is easy to generate bubbles, white edges and other phenomena;
the existing cover plate and display module wet glue full-lamination process generally fixes a liquid crystal display module on a carrier by using an auxiliary adhesive tape, coats glue on the liquid crystal display module, covers the cover plate on the glue, and stands for more than or equal to 10H fixed telephone (normal temperature), so that full lamination is formed.

step four: coating glue on the liquid crystal display module, and covering the cover plate on the glue for attaching;
step five: and (4) tearing off the adhesive tape after heating and curing to form complete lamination.
As a further improvement of the technical solution, in the first step, the unpacked cover plate and the liquid crystal display mold need to be subjected to IOC inspection, where IQC, i.e. incoming material quality inspection, refers to quality confirmation and inspection of the purchased raw materials, parts or products, i.e. the products are inspected by sampling when the suppliers send the raw materials or parts, and finally, a judgment is made as to whether the batch of products are received or returned, thereby further improving the production quality of the products.
As a further improvement of the technical scheme, in the third step, before the liquid crystal display module is placed in the jig, Bezel sealing treatment is required, so that the liquid crystal display module is protected, and the stress is even when the rubber and the liquid crystal display module are conducted.
As a further improvement of the technical scheme, in the fifth step, the heating temperature is 50-60 ℃, the heating time is 20-25min, and the cover plate and the liquid crystal display module can be conveniently and fully attached.
As a further improvement of the technical scheme, in the fifth step, after the adhesive tape is torn off, a post-sealing process is required, and the adhesive tape is kept stand and then is put into a warehouse.
As a further improvement of the technical scheme, in the fifth step, the packaging is carried out after standing, then the packaging cleaning procedure is carried out, and the products are put in storage and delivered after OQC inspection, so that the product delivery quality is improved conveniently.
Compared with the prior art, the invention has the beneficial effects that:
1. in the wet glue full-laminating process of the cover plate and the display module, the liquid crystal display module is placed in the corresponding jig, four sides of the liquid crystal display module are attached by using the auxiliary adhesive tapes, glue is coated on the liquid crystal display module, the cover plate is covered on the glue, and the cover plate is heated for 50-55 degrees for 20-25min to fix the phone, so that full lamination is formed, the utilization rate of a single jig achieves a better effect, and the productivity is greatly improved on the original basis.
