The attaching direction is a direction in which the first film material 41 to be attached moves relative to the second film material 42 to be attached, and in fig. 3, the attaching direction is a vertical direction.

Note that the bonding process is a process in which the first film material to be bonded 41 and the second film material to be bonded 42 are gradually brought closer to each other to be bonded. In the laminating process, the fixing jig drives the first film material to be laminated 41 to move towards the second film material to be laminated 42; or, the attaching jig drives the second film material to be attached 42 to move toward the first film material to be attached 41; or, the fixing jig drives the first film material 41 to be attached to move toward the second film material 42 to be attached, and the attaching jig drives the second film material 42 to be attached to move toward the first film material 41 to be attached.

In one embodiment, the material of conformable pad 33 may be an elastic material, such as silicone, and conformable pad 33 using an elastic material may be a flexible pad, such as a silicone pad. The attaching pad 33 made of the elastic material has good profiling capability, and in the attaching process, the attaching pad 33 can deform along with the shape of the second film material 42 to be attached, so that the attaching effect is further improved.

The thickness of fit pad 33 may be set as needed, and is not particularly limited.

As shown in fig. 3, the second film material 42 to be bonded has a second bonding surface 421 facing the first film material 41 to be bonded, for example, an optical adhesive layer (OCA) may be disposed on the surface of the second bonding surface 421, and after the second film material 42 to be bonded is bonded to the first bonding surface 411, the optical adhesive layer may improve bonding firmness.

In one embodiment, the distance between the first attaching surface 411 and the second attaching surface 421 gradually increases from the attaching start position a toward both sides in the attaching direction between attaching, that is, before the second film material to be attached 42 contacts the first attaching surface 411 of the first film material to be attached 41.

In one embodiment, the compression stroke amount of the elastic member 32a corresponding to the attachment start position a is greater than the compression stroke amount of the elastic members 32b located at both sides of the attachment start position a. It should be noted that, the first film material 41 to be attached is an arc shape protruding toward the second film material 42 to be attached, and the compression stroke amount of the elastic member corresponding to the attachment starting position a is set to be greater than the compression stroke amounts of the elastic members located on both sides of the attachment starting position a, so that in the attachment process, the second film material 42 to be attached deforms along with the shape of the first film material 41 to be attached, and finally, the shape of the second film material 42 to be attached is matched with the shape of the first film material 41 to be attached, thereby better achieving the attachment of the first film material and the second film material.

In one embodiment, as shown in fig. 3, the elastic members located at both sides of the attachment start position a are symmetrically disposed with respect to the attachment start position a. Therefore, in the laminating process, the stress on the two sides of the laminating initial position A is symmetrical, and the symmetrical laminating conditions on the two sides of the laminating initial position A are guaranteed, so that the two sides of the laminating initial position A are synchronously laminated, and the laminating effect uniformity is provided.

The number and the interval of the elastic pieces on the two sides of the attaching starting position A can be set according to requirements as long as the elastic pieces on the two sides are symmetrical.

In one embodiment, as shown in fig. 3, the supporting platform 31 has a plurality of positioning slots 311, the positioning slots 311 correspond to the elastic members one by one, and one end of each elastic member facing the supporting platform 31 is located in the corresponding positioning slot 311.
