Problems solved by technology

However, since the protective glass is 10-15mm larger than the one side of the OCA adhesive, the adhesion accuracy is not easy to control, and OCA glue overflow or OCA deviation will occur after hard-to-hard lamination

Embodiment Construction

[0017] Such as Figure 1 to Figure 3 As shown, the CTP full bonding process proposed by the present invention includes the following steps:

[0018] S1. Adhesive: Take the touch screen 1 and place it on the soft-to-hard platform and fix it, use the nozzle platform to suck the OCA glue 2 and stick the OCA glue 2 on the touch screen 1;

[0019] S2, heating: heating the touch screen 1 with the OCA glue 2 attached, the heating temperature is 35~45℃, and the heating time is 20-25s;

[0020] S3. Laminating: Take the protective glass 3, place it on a hard-to-hard platform and fix it, and glue the touch screen 1 with the OCA glue 2 and the protective glass 3 together.

[0021] Before step S1, it also includes the steps of cleaning; before the touch screen 1 is placed on the soft-to-hard platform, the touch screen 1 is cleaned; before the protective glass 3 is placed on the hard-to-hard equipment platform, the protective glass 3 is cleaned, and the touch screen 1 and The protective glass 3 ca...

Abstract

The invention discloses a CTP full fitting technology which comprises the following steps: rubberizing: putting a touch screen on a soft-hard equipment platform, fixing the touch screen, using a suction nozzle platform to absorb OCA glue, and fitting the OCA glue on the touch screen; heating: heating the touch screen fitting with the OCA glue, wherein the heating temperature is 35-45 DEG C and the heating time is 20-25 s; fitting: putting protective glass on a hard-hard equipment platform, fixing the protective glass, and fitting the touch screen fitting with the OCA glue with the protective glass. With adoption of the CTP full fitting technology, after hard-hard fitting, the phenomenon that the OCA glue overflows or is off normal can be avoided, the reworking and scrapping rate of the OCA glue is directly and effectively decreased, and the production efficiency is improved; in addition, the equipment platforms do not need to be modified, and the idler wheel stroke is also sufficient.

Description

Technical field [0001] The invention relates to the field of touch screen processing, and more specifically to a CTP full bonding process. Background technique [0002] In the CTP (multi-point capacitive touch screen) full bonding production process, the commonly used bonding process technology is to simulate the full bonding method of LCM (liquid crystal display module) production, that is, OCA glue is attached to the protective glass, and then the The protective glass with OCA glue is attached to the LCD module. Because the OCA is attached to the protective glass, the protective glass has no marking points, and the attachment is misaligned. After the final hard-to-hard bonding, the OCA glue overflows or the OCA glue is offset, which cannot meet the requirements of precise placement. [0003] The common CTP full bonding method in the prior art is to first adhere the OCA glue to the protective glass on the soft-to-hard platform, and then adhere the touch screen and the protective ...
