Referring to fig. 2 to 5, fig. 5 is a schematic partial structure of a support member in a use state according to an embodiment of the utility model.

As shown in fig. 2 to 5, in the use state of the support member, the flexible screen 20 and the flexible support table 200 are aligned in the first direction Z. In the aligned state, the gap g between the flexible screen 20 and the flexible support table 200 may be set to 0 to 1.0mm. In this state, the edge of the flexible screen 20 is aligned with the support surface 210, and the inclined surface 213 is provided with a mark point a aligned with the edge of the flexible screen 20 in the first direction Z.

In some alternative embodiments, the inclined surface 213 and the curved surface 212 are adjoined by a connecting edge b, which is at a distance n of 0.2mm to 0.7mm from the marking point a in the second direction X. Alternatively, as shown in fig. 2, the connecting edge b may be considered as the boundary between the inclined surface 213 and the curved surface 212.

In these alternative embodiments, when the distance n between the connecting edge b and the mark point a in the second direction X is set within the above range, it is improved that the distance n between the connecting edge b and the mark point a in the second direction X is too small to cause contact in advance during the bonding process of the curved cover plate 10 and the flexible screen 20, so that bonding bubbles between the curved cover plate 10 and the flexible screen 20 cannot be discharged; meanwhile, the defect of insufficient bonding force caused by the overlarge distance n between the connecting edge b and the mark point a in the second direction X can be overcome, and bonding bubbles are generated between the long edge of the curved cover plate 10 and the flexible screen 20.

In some alternative embodiments, the inclined surface 213 extends over a dimension h of 3mm to 7mm in the first direction Z.

In these alternative embodiments, when the extension dimension h of the inclined surface 213 in the first direction Z is within the above-described range, it is possible to improve both the influence on the support of the flexible support table 200 due to the excessive extension dimension of the inclined surface 213 in the first direction Z, and the defect that the curved cover plate 10 is susceptible to cracking or the like due to the excessive thickness of the flexible support table 200 due to the insufficient extension dimension of the inclined surface 213 in the first direction Z.

In these alternative embodiments, the peripheral side 120 of the base 100 is provided with a relief groove 130, and the relief groove 130 is formed to be recessed toward the inside of the base 100. By arranging the avoiding groove 130, on one hand, the weight of the base 100 can be reduced, and the preparation material of the base 100 can be saved; on the other hand when the supporting component is used for supporting the laminating of flexible screen 20 and curved surface apron 10, utilize clamping component 400 centre gripping flexible screen 20 and supporting component to counterpoint, dodge groove 130 and can provide the position of stepping down for clamping component 400, reduce the interval between two clamping components 400, increase the crooked degree of flexible screen 20 for flexible screen 20 can adapt to the curved surface apron 10 of big camber better, improves the laminating bubble problem between curved surface apron 10 and the flexible screen 20 better.

In some alternative embodiments, the peripheral side surface 120 includes two first side surfaces 121 disposed opposite to each other along the second direction X and two second side surfaces 122 disposed opposite to each other along the third direction Y, and an extension length of the first side surfaces 121 in the third direction Y is greater than an extension length of the second side surfaces 122 in the second direction X, and at least one of the first side surfaces 121 is provided with the escape groove 130.

The escape groove 130 is disposed on the first side 121, so that the escape groove 130 can accurately provide a relief for the clamping member 400.

The shape of the avoiding groove 130 is various, the avoiding groove 130 includes an opening 131 and a bottom surface 132 connected with the opening 131, and the cross-sectional shape of the bottom surface 132 in the plane 211 where the second direction X and the first direction Z are located may be arc-shaped or fold-line-shaped.

Alternatively, as shown in fig. 8 and 9, the pick-up member 300 includes a clamping jaw for clamping the curved cover plate 10, for example, the clamping jaw clamps the curved cover plate 10 from an included angle position of the curved cover plate 10. Optionally, the curved cover plate 10 has an arc portion, and the arc portion is bent around the circumference of the curved cover plate 10.

During the process of gripping the curved cover plate 10 by the gripping jaw (i.e., the pickup element 300) gradually approaches the flexible screen 20, if the shape of the flexible supporting table 200 and the shape of the curved cover plate 10 are adapted, for example, as shown in fig. 8 and 9, the supporting side surface 220 of the flexible supporting table 200 and the arc surface 212 are directly connected at right angles, which results in the size of the flexible supporting table 200 being slightly larger than the size of the curved cover plate 10, the gripping jaw may erroneously touch the flexible supporting table 200 before the curved cover plate 10 and the flexible screen 20 are contacted, resulting in the occurrence of a bonding bubble between the curved cover plate 10 and the flexible screen 20. The outline of the flexible support table 200 is illustrated in phantom in fig. 9, and it can be seen that the outline of the flexible support table 200 and the outline of the pickup 300 interfere with each other in spatial position.

The arcuate region 230 may be provided in a variety of ways, alternatively, the arcuate region 230 may be slightly larger than the size of the corner portion of the flexible screen 20 to be supported by the flexible support platform 200, i.e., the corner portion of the flexible screen 20 that extends in different directions and includes an angled region between adjacent sides. Optionally, the arcuate region 230 includes a first sub-region for supporting a corner of the flexible screen 20 and a second sub-region located at a center of the first sub-region away from the support surface 210. So that the arcuate region 230 provides better support to the corner and improves the fit of the air bubbles between the corner and the curved cover plate 10.
