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 present invention. It should be noted that, in the embodiment, the transportation process of the device applied to the curved display screen is taken as an example for explanation, which is only needed for discussion, and thus, the application environment of the device is not limited.
In one embodiment, an apparatus for manufacturing a curved display screen includes a first carrier assembly 20 and a second carrier assembly 30. The first bearing assembly 20 has a first bearing surface 21, and the second bearing assembly 30 has a second bearing surface 31, wherein the first bearing surface 21 is used for bearing a screen body of the 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 coupled to the first bearing assembly 20 and/or the second bearing assembly 30 for moving the first bearing assembly 20 and the second bearing assembly 30 relative to each other along a first direction (as indicated by an arrow Z in fig. 2, the same applies below) so that the first bearing surface 21 and the second bearing surface 31 are spaced apart from each other along 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 from each other in the first direction.
The first direction may be a vertical direction when the device is properly installed in a module factory line. In other words, the adjusting assembly 50 of the present embodiment drives the first bearing assembly 20 and the second bearing assembly 30 to move relatively 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 a curved display screen, the screen body and the circuit board are not coplanar. In this embodiment, the first supporting surface 21 and the second supporting surface 31 have a height difference, and can be well adapted to a product form in which the screen body of the curved display screen and the circuit board are not coplanar, which means that the first supporting surface 21 can well support the screen body, and the second supporting surface 31 can also well support the circuit board. Therefore, 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.
It should be noted that, when the first carrying surface 21 carries the screen body and the second carrying surface 31 carries the circuit board body, a distance between the first carrying surface 21 and the second carrying surface 31 in the first direction is equal to a distance between the screen body and the circuit board body in the first direction. The distance between the screen body and the circuit board body in the first direction is understood to be the distance between the surface of the screen 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 partial schematic structural view 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 adjustment portion 52 is disposed on the first carrier assembly 20, and the second adjustment portion 53 is disposed on the second carrier assembly 30. The first adjusting part 51 is arranged through the first adjusting part 52 and the second adjusting part 53, and the first adjusting part 51 is in threaded fit connection with at least one of the first adjusting part 52 and the second adjusting part 53. That is, the first adjusting member 51 is only connected with the first adjusting portion 52 in a threaded fit manner, or the first adjusting member 51 is only connected with the second adjusting portion 53 in a threaded fit manner, or the first adjusting member 51 is connected with both the first adjusting portion 52 and the second adjusting portion 53 in a threaded fit manner.
In this manner, the central axis of the first regulating member 51 extends in the first direction. The first adjusting member 51 rotates around its central axis, so as 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 adjusting member 51 includes a manipulation part 511 and a lever part 512 connected to each other. The rod portion 512 penetrates 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 shaft portion 512 may be a threaded rod, the outer circumference of which is provided with threads, and the first adjustment part 52 and/or the second adjustment part 53 are provided with threaded holes to be threadedly coupled with the shaft portion 512 of the first adjustment member 51.
A control handle 513 is disposed on a side of the control portion 511 away from the rod portion 512, and the control handle 513 extends along the first direction. The lever 512 is driven to rotate around its central axis by operating the handle 513 to rotate around the central axis of the lever 512 (i.e. the central axis of the first adjusting member 51).
For example, as shown in fig. 4, the manipulation part 511 is disc-shaped, the center of the manipulation part 511 is located on the central axis of the rod part 512, the manipulation handle 513 is spaced from the central axis of the rod part 512, and a user grasps the manipulation handle 513 and drives the manipulation handle 513 to rotate the manipulation part 511 around the central axis of the rod part 512, so as to drive the rod part 512 to rotate through the manipulation part 511, and further drive the first adjustment part 52 and the second adjustment part 53 to move relatively along the first direction through the screw thread fit. The user can conveniently drive the first bearing assembly 20 and the second bearing assembly 30 to move relatively by the aforementioned shaking manner, so that the first bearing surface 21 and the second bearing surface 31 form the aforementioned height difference.
Further, the adjustment assembly 50 includes a locking member 541. The first load bearing member 20 and/or the second load bearing member 30 are provided with a kidney-shaped hole 542, and the kidney-shaped hole 542 extends in the first direction. The locking member 541 connects the first bearing assembly 20 and the second bearing assembly 30, and penetrates through the kidney-shaped hole 542.
When the first bearing assembly 20 and the second bearing assembly 30 are required to bear the curved display screen, the locking member 541 is loosened, and the relative movement between the first bearing assembly 20 and the second bearing assembly 30 is allowed, so that the first bearing surface 21 and the second bearing surface 31 form the height difference to adapt to the product form of the curved display screen; when the locking member 541 is locked, that is, 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, and further reliably bear the curved display screen.
For example, fig. 4 shows the second carrier assembly 30 having a kidney-shaped aperture 542. Specifically, the second carrier assembly 30 includes a carrier bracket 32 and a connecting bracket 33. The carrier bracket 32 is provided with a carrier 60, and a surface of the carrier 60 for carrying the circuit board is the second carrier 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 connecting bracket 33 is provided with a kidney-shaped hole 542, and the locker 541 is connected to the first carrier assembly 20 through the kidney-shaped hole 542. During the relative movement of the first bearing assembly 20 and the second bearing assembly 30, the locking member 541 synchronously moves along the kidney-shaped hole 542, and after the locking member 541 is locked, the adjusted relative positions of the first bearing assembly 20 and the second bearing assembly 30 are fixed.
Alternatively, the locking member 541 may be a bolt, etc., and is not limited thereto.
