Abstract

An detachment device for a spliced display device includes: a detachment mechanism disposed to be connected with the first display unit to drive the first display unit to move along a direction away from or close to a plane where the spliced display device is located; at least one moving device, wherein the moving device includes a moving frame located outside the detachment mechanism and an adjustment member disposed on the moving frame, the moving frame is connected with the second display unit, the adjustment member abuts against the detachment mechanism, and the moving frame drives the second display unit connected with the moving frame to move in a direction away from the first display unit through the adjustment member on the plane where the spliced display device is located.

First claim

The invention claimed is:

1. A detachment device for a spliced display device, wherein the spliced display device comprises a first display unit and a second display unit adjacent to the first display unit, wherein the first display unit and the second display unit are spliced with each other; the detachment device for spliced display device comprises:
a detachment mechanism disposed to be connected with the first display unit to drive the first display unit to move along a direction away from or close to a plane where the spliced display device is located; and
at least one moving device, wherein
the moving device comprises a moving frame located outside the detachment mechanism and an adjustment member disposed on the moving frame,
the moving frame is connected with the second display unit,
the adjustment member abuts against the detachment mechanism, and
on the plane where the spliced display device is located, the moving frame drives the second display unit connected with the first moving device to move along a direction away from the first display unit through the adjustment member.

2. The detachment device for spliced display device according to claim 1 , comprising a first moving device located on opposite sides of the detachment mechanism in a first direction and a second moving device located on opposite sides of the detachment mechanism in a second direction, wherein
the first moving device and the second moving device are respectively connected with different second display units,
the first moving device drives the second display unit connected with the first moving device to move along the first direction,
the second moving device drives the second display unit connected with the second moving device to move along the second direction,
the first direction intersects the second direction, and
both the first direction and the second direction are parallel to the plane where the spliced display device is located.

3. The detachment device for spliced display device according to claim 1 , wherein the moving device further comprises a support post disposed on the moving frame, and the support post is connected with the second display unit.

4. The detachment device for spliced display device according to claim 1 , wherein the moving device further comprises a guide rail disposed on the moving frame, the guide rail is slidably connected with the moving frame and fixedly connected with the detachment mechanism.

5. The detachment device for spliced display device according to claim 1 , wherein the moving device further comprises a fastener disposed on the moving frame, the fastener is fastened and connected with a first end of the detachment mechanism, and the adjustment member abuts against a second end of the detachment mechanism.

6. The detachment device for a spliced display device according to claim 1 , wherein the adjustment member is of a micrometer head structure.

7. The detachment device for a spliced display device according to claim 1 , wherein
the detachment mechanism comprises a fixing frame, a guide post disposed on the fixing frame, and a detachment member slidably connected with the guide post,
the adjustment member abuts against the fixing frame,

the detachment member is slidably connected with the guide post, and
the detachment member comprises a connecting post disposed to be connected with the first display unit.

8. The detachment device for spliced display device according to claim 7 , wherein the detachment mechanism further comprises a first alignment device and a second alignment device disposed at intervals on the fixing frame, the first alignment device is aligned with a first corner position of the first display unit, and the second alignment device is aligned with a second corner position of the first display unit.

9. The detachment device for spliced display device according to claim 7 , wherein the detachment member further comprises a bearing substrate, the bearing substrate is slidably connected with the guide post, and the connecting post is disposed on the bearing substrate.

10. The detachment device for a spliced display device according to claim 9 , wherein the detachment member further comprises a handle disposed on a side of the bearing substrate away from the connecting post.

11. A detaching method of a detachment device for a spliced display device according to claim 1 , comprising:
connecting the detachment mechanism with the first display unit, and connecting the moving frame of the moving device with the second display unit, so that the adjustment member of the moving device abuts against the detachment mechanism;
on the plane where the spliced display device is located, driving, by the moving frame, the second display unit connected with the moving frame to move along a direction away from the first display unit through the adjustment member, so that a splicing gap between the second display unit and the first display unit reaches a predetermined value; and
driving, by the detachment mechanism, the first display unit to move along the direction away from the spliced display device, so that the first display unit and the second display unit are detached and separated.

12. The detachment device for a spliced display device according to claim 2 , wherein the adjustment member is of a micrometer head structure.

13. The detachment device for a spliced display device according to claim 3 , wherein the adjustment member is of a micrometer head structure.

14. The detachment device for a spliced display device according to claim 4 , wherein the adjustment member is of a micrometer head structure.

15. The detachment device for a spliced display device according to claim 2 , wherein
