[0021] Reference Numerals:

[0022] Laminating platen 10, protective film layer 20, outer film layer 21, inner film layer 22, tear handle 23, cover plate material 30, glue application area 31. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0024] The present application provides a liquid glue laminating jig. Please refer to Figure 1 and Figure 2, including: a bonding platen 10 and a protective film layer 20. The protective film layer 20 includes an outer film layer 21 and an inner film layer 22. The outer film layer 21 is hollow inside, and the inner film layer 22 is tearably connected inside the outer film layer 21. The cover material 30 is disposed on the bonding platen 10, and the protective film layer 20 is bonded to the cover material 30. The staff tears off the inner layer film on the cover material 30 to avoid the glue application area 31 of the cover material 30. The cover material 30 coated with liquid glue is bonded and fixed to the thin film transistor liquid crystal display glass material. When the thin film transistor liquid crystal display glass material is bonded to the cover material 30, the liquid glue on the cover material 30 is extruded by the thin film transistor liquid crystal display glass material and overflows to the four peripheral edges of the cover material 30. Since the outer film layer 21 is bonded to the

[0025] cover material 30, it overflows onto the outer film layer 21 of the protective film layer 20, so it will not adhere to the non-glue application area 31 of the cover material 30. The protective film layer 20 prevents the liquid glue from overflowing onto the non-glue application area 31 of the cover material 30. After the thin film transistor liquid crystal display glass material and the cover material 30 are pressed together, the outer film layer 21 and the excess liquid glue overflowing on the outer film layer 21 are torn off, thus saving the deburring process, improving work efficiency, and ensuring product quality.

[0026] It should be noted that the liquid glue is a liquid optical glue, which can be OCR optical glue or OCA optical glue. The liquid glue is applied in a "Y shape" or "X shape" in the glue application area 31 of the cover material 30. When the display glass material is pressed into the glue application area 31 of the cover material 30, the liquid glue can be evenly extruded in the glue application area 31, saving glue, avoiding the fast flow rate of the liquid glue during bonding and entering the bottom of the protective film, and improving work efficiency. Moreover, a groove is provided on the bonding platen 10 for positioning the cover material 30 to prevent the thin film transistor liquid crystal display glass material from shifting during the pressing process and affecting the bonding accuracy.

[0027] In one embodiment, in order to facilitate the staff to tear off the inner film layer 22, the outer film layer 21 and the inner film layer 22 are connected in a point-break manner. Preferably, the protective film layer 20 is rectangular, and the shape of the inner film layer 22 is rectangular. Further, in order for the protective film layer 20 to closely adhere to the cover material 30, a sticky layer is provided on the bonding surface of the protective film layer 20 and the cover material 30. The protective film layer 20 is bonded to the cover material 30 through the sticky layer, thereby preventing the liquid glue overflowing from the cover material 30 from entering the bottom of the outer film layer 21 and achieving a better bonding effect.

[0028] In one embodiment, please refer to Figure 1, a tear handle 23 is convexly provided on the outer side of the outer film layer 21, and no adhesive layer is provided on the bonding surface of the tear handle 23 and the bonding table board 10, so that the staff can quickly tear off the outer film layer 21, improving work efficiency. Preferably, tear handles 23 are respectively convexly provided on both sides of the outer film layer 21. Similarly, a starting groove is provided on the bonding table board 10 at the corresponding position of the tear handle 23, so that the staff can quickly grasp the tear handle 23, thereby improving work efficiency. Further, the size of the outer film layer 21 is the same as the size of the cover plate material 30, saving the material of the outer film layer 21 while ensuring the degumming effect and reducing the manufacturing cost.

[0029] In addition, the length of the inner film layer 22 is 0.3 mm greater than the length of the thin-film transistor liquid crystal display glass material, and the width of the inner film layer 22 is 0.3 mm greater than the width of the thin-film transistor liquid crystal display glass material. When the staff tears off the outer film layer 21, it is avoided that the liquid glue on the outer film layer 21 touches the cover plate material 30 and the thin-film transistor liquid crystal display glass material, further ensuring the degumming effect and guaranteeing the product quality.

[0030] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
