[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figures 1 to 4 The jig shown is for curved IML housing and FOG full mounting, including:

[0025] Jig body 1;

[0026] It also includes an IML curved plate 2 and a FOG plate 3;

[0027] An IML limiting groove 4 is provided on the top of the fixture body 1, and a FOG limiting groove 5 is provided in the middle section of the IML limiting groove 4. The FOG plate 3 is clamped in the FOG limiting groove 5, and the IML curved plate 2 is located in the IML limiting groove 4. The IML curved plate 2 includes a flat layer 21 in the middle section and curved layers 22 at both ends. The IML limiting groove 4 includes a flat groove 41 in the middle section and avoidance grooves 42 extending downward at both ends.

[0028] By sequentially opening an IML limiting groove 4 and a FOG limiting groove 5 on the top of the jig body 1, the IML curved plate 2 and the FOG plate 3 are placed. At the same time, the flat groove 41 and the avoidance groove 42 in the IML limiting groove 4 correspond to the flat layer 21 and the curved layer 22 of the IML curved plate 2, which facilitates the tight fitting of the FOG plate 3 and the IML curved plate 2 at the position of the flat layer 21, thereby facilitating the fitting process and ensuring the excellent hard-to-hard fitting rate of the curved IML and FOG.

[0029] Two sets of positioning grooves 6 are provided on the top of the jig body 1. The positioning grooves 6 are located on the front and rear sides of the IML limit grooves 4. The setting of the positioning grooves 6 makes it convenient to position the jig body 1 when using a pressing machine for extrusion, ensuring that the IML curved plate 2 and the FOG plate 3 remain stable with the jig body 1, and preventing the IML curved plate 2 and the FOG plate 3 from offsetting inside the jig body 1 and causing fitting failure.

[0030] OCA glue 7 is coated between the IML curved panel 2 and the FOG panel 3. The area of the OCA glue 7 is the area of the overlapping part of the IML curved panel 2 and the FOG panel 3. By coating the OCA glue 7 between the IML curved panel 2 and the FOG panel 3, a bonding effect is achieved. At the same time, the coating area of the OCA glue 7 is the area of the overlapping part of the curved panel and the FOG panel 3 to ensure the stability of the extrusion bonding and save the use of the OCA glue 7.

[0031] The depth of the FOG limit groove 5 is less than the thickness of the FOG board 3, and the thickness of the flattening layer 21 is greater than the depth of the flattening groove 41. By limiting the depth of the FOG limit groove 5 and the flattening groove 41, it is convenient to have sufficient extrusion space when the IML curved panel 2 and the FOG board 3 are extruded and laminated using a laminating machine, thereby ensuring that the IML curved panel 2 and the FOG board 3 are tightly fitted.

[0032] One side of the FOG limiting groove 5 extends backward and passes through the fixture body 1. By setting the shape of the FOG limiting groove 5, the FPC can be placed to prevent the FPC connected to the FOG board 3 from being squeezed and damaged.

[0033] During specific use, the POG board is placed in the FOG limit groove 5, and then OCA glue 7 is coated on the FOG board 3, and then the IML curved panel 2 is placed in the IML limit groove 4, so that the curved layer 22 at both ends of the IML curved panel 2 is placed in the avoidance groove 42, and the flat layer 21 in the middle section is bonded to the FOG board 3, and then the aligned product is placed together with the jig into the vacuum pressing machine for pressing, so that the FOG board 3 and the IML curved panel 2 are bonded under a vacuum state. Because the IML limit groove 4 is made according to the product curved surface drawing, the bonding area between the FOG board 3 and the IML curved panel 2 can be maximized during the pressing process, and the generation of bubbles can be reduced.

[0034] Note:

[0035] IML: In-mold insert injection molding process plastic cover, the base material is generally PET and PC, combined with an ink layer and adhesive, commonly used in the automotive display industry.

[0036] FOG: The part where the TFT glass is bonded to the FPC. It is the state of the LCM display before the backlight assembly is assembled. It is commonly used in display industries such as automotive and TV.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
