Referring to fig. 1, an embodiment of the present application provides a screen assembly apparatus, which includes a positioning device 100 and a cover 200, wherein the cover 200 is rotatably connected to the positioning device 100. The positioning device 100 is configured to carry a first object 310. The cover plate 200 may, but is not limited to, absorb the second object 320 through the suction nozzle, thereby temporarily fixing the second object 320 to the cover plate 200. With this structure, the second object 320 can be assembled on the first object 310 by rotating the cover plate 200.

In the embodiment of the present application, the screen assembling device is used for assembling a screen, the first object 310 may include a back panel, a middle frame, and the like, the second object 320 may include a display panel, and the like, and the first object 310 and the second object 320 may be assembled together by the screen assembling device, so as to obtain the screen.

As shown in fig. 2 and 3, the positioning device 100 includes a stage 110, a top plate 120, a lift drive 130, and at least two clamping assemblies 140. The carrier 110 is provided with a carrying structure 111, and the carrying structure 111 is used for carrying the first object 310. The top plate 120 is disposed at one side of the carrier 110 along the height direction, and the lift driving member 130 is used to drive the top plate 120 to approach and separate from the carrier 110 along the height direction.

Corresponding clamping assemblies 140 are provided at least on opposite sides of the carrier structure 111, respectively. For example, in the embodiment of the present application, the positioning device 100 includes six clamping assemblies 140, where two clamping assemblies 140 are respectively disposed on two opposite sides in the length direction of the carrier 110, and four clamping assemblies 140 are respectively disposed on two opposite sides in the width direction of the carrier 110, and each clamping assembly 140 cooperates with the corresponding clamping assembly 140 to clamp the first object 310 on the carrying structure 111.

Referring to fig. 4 to fig. 6 together, the clamping assembly 140 includes an elastic member 141, a clamping module 142 and an abutment module 143, and the clamping module 142 is disposed between the elastic member 141 and the abutment module 143; the clamping module 142 is movably connected to the carrier 110 along a horizontal direction, and the elastic member 141 is used for making the clamping module 142 approach the first object 310 along the horizontal direction; the abutment module 143 is fixed to the top plate 120, and the abutment module 143 abuts the clamping module 142.

When the jacking driving member 130 drives the top plate 120 away from or near the stage 110, the elastic member 141 makes the clamping module 142 approach the first object 310 along the horizontal direction. That is, when the lift driving member 130 drives the top plate 120 away from the stage 110, the elastic member 141 brings the clamping modules 142 close to the first object 310, so that the clamping modules 142 on opposite sides of the carrying structure 111 clamp the first object 310, and when the lift driving member 130 drives the top plate 120 close to the stage 110, the elastic member 141 brings the clamping modules 142 away from the first object 310, so that the clamping modules 142 on opposite sides of the carrying structure 111 unclamp the first object 310; or alternatively, the process may be performed,

when the lift driving member 130 drives the top plate 120 to approach the stage 110, the elastic member 141 approaches the clamping modules 142 to the first object 310 in the horizontal direction, so that the clamping modules 142 on opposite sides of the carrying structure 111 clamp the first object 310, and when the lift driving member 130 drives the top plate 120 away from the stage 110, the elastic member 141 moves the clamping modules 142 away from the first object 310, so that the clamping modules 142 on opposite sides of the carrying structure 111 unclamp the first object 310. With this arrangement, the first object 310 can be positioned, so that the placement accuracy of the first object 310 on the carrier 110 is effectively improved.

It should be noted that the clamping module 142 is movably connected to the carrier 110 along the horizontal direction means that the clamping module 142 is disposed on the carrier 110, and the clamping module 142 can move relative to the carrier 110 along the horizontal direction. The height direction is perpendicular to a horizontal direction, which refers to a direction parallel to a plane in which the stage 110 is located, and for example, the horizontal direction may include a length direction and a width direction of the stage 110.

In particular, as shown in fig. 4-6, the clamping assembly 140 further includes a first positive stop 144 and a first guide 145. The first limit stop 144 is fixed to the carrier 110, and the first limit stop 144 is located on a side of the clamping module 142 away from the abutment module 143. The first guide 145 is fixed to the first bump stop 144, and the first guide 145 is located between the first bump stop 144 and the clamping module 142. The elastic member 141 is sleeved outside the first guiding member 145, and two ends of the elastic member 141 are respectively abutted against the first limit stop 144 and the clamping module 142. With this structure, the elastic member 141 may cause the clamping module 142 to have a tendency to approach the receiving structure in the horizontal direction, thereby causing the clamping module 142 at opposite sides of the carrying structure 111 to clamp the first object 310.

Alternatively, the elastic member 141 may be a spring, and of course, the elastic member 141 may be other elastic members, which are not limited herein.

The clamping module 142 is fixed on the connecting base 146, and the connecting base 146 is slidably connected to the carrier 110 along a horizontal direction, so that the clamping module 142 is movably connected to the carrier 110 along the horizontal direction. The second limit stop 147 is disposed on the connecting seat 146, the second limit stop 147 is disposed between the first limit stop 144 and the clamping module 142, the second limit stop 147 is provided with a limit groove 1471, one end of the elastic member 141, which is far away from the first limit stop 144, is abutted against the bottom wall of the limit groove 1471, and one end of the first guide member 145, which is far away from the first limit stop 144, passes through the bottom wall of the limit groove 1471. Under this structure, the end of the elastic member 141 far away from the first limit stop 144 is indirectly abutted against the clamping module 142 through the second limit stop 147, and the limit groove 1471 can play a limiting role on the elastic member 141, so as to avoid radial displacement when the elastic member 141 is compressed, and effectively improve the reliability of the clamping assembly 140. In this embodiment, the first limit stop 144 is provided with a limit groove 1441, and an end of the elastic member 141 away from the second limit stop 147 abuts against a bottom wall of the limit groove 1441.

Optionally, the clamping assembly 140 further includes a sliding rail 148 and a sliding block 149, the sliding rail 148 is fixed to the carrier 110, the sliding block 149 is slidably connected to the sliding rail 148 along a horizontal direction, and the connecting base 146 is fixed to the sliding block 149, so that the connecting base 146 is slidably connected to the carrier 110 along the horizontal direction.

In this embodiment, the clamping member 1421 is secured to the connecting housing 146.

Alternatively, the acting surface may include one or both of an arc surface and an inclined surface, that is, the acting surface may be only an arc surface, or the acting surface may be only an inclined surface, or the acting surface may be a combination of the arc surface and the inclined surface, which is not limited only herein.
