Embodiment 1

[0022] Embodiment 1: as figure 1 As shown, a full bonding process of a touch display module includes the following steps:

[0023] S1: The touch display module includes a first base material and a second base material, and a circle of first sealant is coated on the outer edge of the bonding surface of the first base material by a CCD dispenser;

[0024] S2: Use a CCD dispenser to apply a circle of second sealing glue on the outer edge of the bonding surface of the second substrate;

[0025] S3: After the first sealant and the second sealant are naturally cured, use a glue coater to evenly coat AB silica gel on the bonding surface of the first substrate, and AB silica gel is coated on the inner side of the first sealant;

[0026] S4: Use an oven to heat the AB silica gel to cure it;

[0027] S5: Vacuum bonding the second base material and the first base material by using a vacuum laminating machine.

[0028] In step S3, the AB silica gel completely covers the inner area of ​...

Abstract

The invention discloses a full lamination process of a touch display module, which belongs to the technical field of touch display modules, and comprises the following steps: S1, coating a circle of first sealing glue on the outer edge of the lamination surface of a first base material by adopting a CCD (Charge Coupled Device) dispenser, wherein the touch display module comprises the first base material and a second base material; s2, coating a circle of second sealing glue on the outer edge of the bonding surface of the second base material by adopting a CCD glue dispenser; s3, after the first sealing glue and the second sealing glue are naturally cured, uniformly coating AB silica gel on the bonding surface of the first base material by adopting a glue coating machine, and coating the ABsilica gel on the inner side of the first sealing glue; s4, heating the AB silica gel by adopting an oven to cure the AB silica gel; s5, the second base material and the first base material are attached in a vacuum mode through a vacuum attaching machine; the problem of glue seepage in glue coating in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of touch display modules, and more specifically, relates to a full bonding process of touch display modules. Background technique [0002] At present, when making touch display modules, the UV water glue full lamination process is usually used. The process is as follows: 1. Position the first substrate (usually a glass cover or LCD screen) on the machine carrier A , after positioning, the dispensing control block dispenses glue on the first substrate (the conventional pattern of dispensing is a fishbone diagram); 2. After the dispensing is completed, position the second substrate (usually a touch screen) on the machine carrier B , After positioning, the carrier B is turned over and pressed with the carrier A; 3. After the pressing is completed, the UV tunnel furnace is cured; 4. After the curing is completed, the glue is removed. There is glue bleeding problem in the prior art. Contents of the inv...
