wherein the first movable clamp plate assembly 300 comprises one or more first movable clamp plates 310, the first movable clamp plates 310 are disposed opposite to the first positioning baffle 100, and the second movable clamp plate assembly 400 comprises one or more second movable clamp plates 410, and the second movable clamp plates 410 are disposed opposite to the second positioning baffle 200.

The assembly fixture provided by the embodiment is provided with the first movable clamping plate 310 corresponding to the first positioning baffle 100, the second movable clamping plate 410 corresponding to the second positioning baffle 200, the first movable clamping plate 310 pushes the splicing members 1000 arranged along the second splicing direction D2, the second movable clamping plate 410 pushes the splicing members 1000 arranged along the first splicing direction D1, so that the assembly and positioning of the splicing members 1000 can be more conveniently completed, and the convenience of assembly operation is improved.

As an alternative embodiment, the splicing member 1000 is a display substrate, and the display substrates are spliced in an array arrangement manner to form a spliced display device. For example, the display substrate may be a COB display substrate, or may be a Mini Led COB display substrate.

After the splicing member 1000 is clamped by the first positioning baffle 100, the second positioning baffle 200, the first movable clamping plate assembly 300 and the second movable clamping plate assembly 400 of the splicing fixture, adjacent splicing members may have a step, resulting in poor flatness of the spliced product. In view of the foregoing, the splicing fixture provided in this embodiment of the present application further includes a splicing loading platform 500, where the splicing loading platform 500 includes a bearing surface for bearing the splicing member 1000, and the first positioning baffle 100, the second positioning baffle 200, the first movable clamping plate assembly 300, and the second movable clamping plate assembly 400 are located at the periphery of the bearing surface.

Further optionally, the bearing surface includes a plurality of vacuum suction holes 510 thereon.

In the present embodiment, since the first movable clamp assembly 300 and the second movable assembly can move with respect to the display substrate, the first movable clamp assembly 300 and the second movable assembly can be moved away from the display substrate in a state that the plurality of display substrates arranged in an array are held and fixed by the loading table 500.

In one embodiment, in order to avoid the assembly of the first positioning baffle 100 and the second positioning baffle 200 blocking the bracket and the tiled display device, the first positioning baffle 100 and the second positioning baffle 200 may be detachably or liftably disposed on the tiled carrier 500, and when the plurality of display substrates arranged in an array need to be clamped, the first positioning baffle 100 is located on the first side of the bearing surface, and the second positioning baffle 200 is located on the second side of the bearing surface, so as to block and position the plurality of display substrates arranged in an array; when a plurality of display substrates arranged in an array are required to be assembled with the bracket, the first positioning baffle plate 100 and the second positioning baffle plate 200 are detached from the assembling carrier 500 or the first positioning baffle plate 100 and the second positioning baffle plate 200 are lowered relative to the assembling carrier 500 so as to avoid the bracket, and the blocking effect of the first positioning baffle plate 100 and the second positioning baffle plate 200 on the bracket is eliminated so as to facilitate the assembly of the bracket with the plurality of display substrates arranged in an array.
