Referring to fig. 2, fig. 2 is a schematic structural diagram of an apparatus for manufacturing a curved display screen according to an embodiment of the invention. It should be noted that, in this embodiment, the carrying process link of the device applied to the curved display screen is described as an example, which is only needed for discussion, and therefore, the application environment of the device is not limited.
In one embodiment, the apparatus for manufacturing a curved display screen includes a first carrier member 20 and a second carrier member 30. The first bearing component 20 is provided with a first bearing surface 21, the second bearing component 30 is provided with a second bearing surface 31, wherein the first bearing surface 21 is used for bearing a screen body of a curved display screen, and the second bearing surface 31 is used for bearing a circuit board of the curved display screen.

The adjusting assembly 50 is connected to the first bearing assembly 20 and/or the second bearing assembly 30, and is configured to move the first bearing assembly 20 and the second bearing assembly 30 relatively along a first direction (as indicated by an arrow Z in fig. 2, and the following is the same), so that the first bearing surface 21 and the second bearing surface 31 are spaced apart from each other in the first direction. In this way, the screen body carried by the first carrying surface 21 and the circuit board carried by the second carrying surface 31 are spaced apart from each other in the first direction.
When the device is correctly placed and installed in a module factory line, the first direction may be a vertical direction. In other words, the adjusting component 50 of the present embodiment drives the first bearing component 20 and the second bearing component 30 to relatively move along the first direction, so that the first bearing surface 21 and the second bearing surface 31 are spaced apart from each other in the first direction, i.e. the first bearing surface 21 and the second bearing surface 31 have a height difference.
For curved display screens, the screen body and the circuit board are not coplanar. In this embodiment, the first bearing surface 21 and the second bearing surface 31 have a height difference, so that the product form of the screen body of the curved display screen and the circuit board which are not coplanar can be well adapted, which means that the first bearing surface 21 can well bear the screen body, and meanwhile, the second bearing surface 31 can also well bear the circuit board. In this way, the first bearing assembly 20 and the second bearing assembly 30 can well bear the curved display screen for carrying the module, which is beneficial to realizing the mass production of the curved display screen.
When the first bearing surface 21 bears the screen body and the second bearing surface 31 bears the circuit board body, the distance between the first bearing surface 21 and the second bearing surface 31 in the first direction is equal to the distance between the screen body and the circuit board body in the first direction. The distance between the panel body and the circuit board body in the first direction is understood to be the distance between the surface of the panel body facing the first carrier assembly 20 and the surface of the circuit board body facing the second carrier assembly 30 in the first direction.
Referring to fig. 4, fig. 4 is a schematic partial structure of the handling system shown in fig. 3.
In one embodiment, the adjusting assembly 50 includes a first adjusting member 51, a first adjusting portion 52, and a second adjusting portion 53. The first adjusting portion 52 is disposed on the first carrying assembly 20, and the second adjusting portion 53 is disposed on the second carrying assembly 30. The first adjusting member 51 is disposed through the first adjusting portion 52 and the second adjusting portion 53, and the first adjusting member 51 is in threaded engagement with at least one of the first adjusting portion 52 and the second adjusting portion 53. I.e. the first adjusting member 51 is only screwed with the first adjusting portion 52, or the first adjusting member 51 is only screwed with the second adjusting portion 53, or the first adjusting member 51 is screwed with both the first adjusting portion 52 and the second adjusting portion 53.
In the above manner, the center axis of the first regulating member 51 extends in the first direction. The first adjusting member 51 can rotate around its central axis to drive the first adjusting portion 52 and the second adjusting portion 53 to move relatively along the first direction, that is, drive the first bearing assembly 20 and the second bearing assembly 30 to move relatively along the first direction.
Further, the first regulating member 51 includes a manipulation part 511 and a lever part 512 connected to each other. The rod portion 512 is disposed through the first adjusting portion 52 and the second adjusting portion 53, and the rod portion 512 is in threaded fit connection with at least one of the first adjusting portion 52 and the second adjusting portion 53. Alternatively, the rod portion 512 may be a threaded rod, the outer circumferential surface of which is provided with threads, and the first adjusting portion 52 and/or the second adjusting portion 53 is provided with a threaded hole to be screw-coupled with the rod portion 512 of the first adjusting member 51.
The side of the manipulation portion 511 facing away from the lever portion 512 is provided with a manipulation handle 513, the manipulation handle 513 extending in a first direction. The lever 513 is rotated around the central axis of the lever 512 (i.e. the central axis of the first adjusting member 51) to drive the lever 512 to rotate around its own central axis.
For example, as shown in fig. 4, the control portion 511 has a disc shape, the center of the control portion 511 is located on the central axis of the rod portion 512, the control handle 513 is spaced from the central axis of the rod portion 512, and the user grasps the control handle 513 and drives the control handle 513 to rotate the control portion 511 around the central axis of the rod portion 512, so that the control portion 511 drives the rod portion 512 to rotate, and further drives the first adjusting portion 52 and the second adjusting portion 53 to move relatively along the first direction through screw engagement. The user can conveniently drive the first bearing assembly 20 and the second bearing assembly 30 to relatively move in a shaking manner, so that the first bearing surface 21 and the second bearing surface 31 form the height difference.
Further, the adjustment assembly 50 includes a lock 541. The first carrier member 20 and/or the second carrier member 30 is provided with a kidney-shaped aperture 542, the kidney-shaped aperture 542 extending in the first direction. The locking member 541 connects the first bearing assembly 20 and the second bearing assembly 30, and is disposed through the waist-shaped hole 542.
When the first bearing component 20 and the second bearing component 30 are required to bear the curved display screen, the locking piece 541 is loosened, and the relative movement between the first bearing component 20 and the second bearing component 30 is allowed, so that the first bearing surface 21 and the second bearing surface 31 form the aforesaid height difference to adapt to the product form of the curved display screen; when the locking member 541 is locked, i.e. the adjustment is completed, the adjusted relative positions of the first bearing assembly 20 and the second bearing assembly 30 are fixed, so as to maintain the adjusted height difference between the first bearing surface 21 and the second bearing surface 31, thereby reliably bearing the curved display screen.
For example, fig. 4 shows that the second carrier assembly 30 is provided with a waist-shaped hole 542. Specifically, the second carrier assembly 30 includes a carrier bracket 32 and a connection bracket 33. The carrier 32 is provided with a carrier 60, and a surface of the carrier 60 for carrying the circuit board is the second carrying surface 31, as shown in fig. 2. The carrier bracket 32 is connected to the first carrier assembly 20 by a connecting bracket 33. The connection bracket 33 is provided with a waist-shaped hole 542, and the locking member 541 is connected to the first carrier assembly 20 through the waist-shaped hole 542. During the relative movement of the first and second carrier members 20 and 30, the locking member 541 moves relatively along the waist-shaped hole 542 in synchronization, and after the locking member 541 locks, the adjusted relative positions of the first and second carrier members 20 and 30 are fixed.
Alternatively, the locking member 541 may be a bolt or the like, which is not limited herein.
