Abstract

A jig for inspecting a display module, the display module including a display module body and a lug, the jig including a bottom plate and a cover plate, the cover plate operatively covering the bottom plate; the bottom plate being provided with a first flat portion and the cover plate being provided with a second flat portion, wherein the bottom plate is provided with a first concave portion surrounded by the first flat portion, and/or the cover plate provided with a second concave portion surrounded by the second flat portion, the first concave portion and/or the second concave portion form(s) a receiving area for the display module body, and the first flat portion and the second flat portion are configured to clamp the lug.

First claim

The invention claimed is:

1. A jig suitable for inspecting a display module, the display module comprising a display module body and a lug, the jig comprising a bottom plate and a cover plate, the cover plate operatively covering the bottom plate, the bottom plate being provided with a first flat portion and the cover plate being provided with a second flat portion, wherein the jig further comprises at least one selected from the group consisting of a first concave portion provided on the bottom plate and surrounded by the first flat portion and a second concave portion provided on the cover plate and surrounded by the second flat portion, the at least one selected from the group consisting of the first concave portion and the second concave portion form(s) a receiving area for the display module body, and the first flat portion and the second flat portion are configured to clamp the lug.

2. The jig according to claim 1 , wherein
in a case where the first concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the bottom plate comprises a first boss, and the first boss is disposed on the first flat portion and surrounds the first concave portion;
in a case where the second concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the cover plate comprises a second boss, and the second boss is disposed on the second flat portion and surrounds the second concave portion; and
in a case where the first concave portion and the second concave portion together form the receiving area for the display module body, the bottom plate comprises the first boss, and
the cover plate comprises the second boss.

3. The jig according to claim 2 , wherein
in a case where the first concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the first concave portion is formed as a placement groove;
in a case where the second concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the second concave portion is formed as a relief groove; and
in a case where the first concave portion and the second concave portion together form the receiving area for the display module body, the first concave portion is formed as the placement groove, and the second concave portion is formed as the relief groove.

4. The jig according to claim 2 , wherein
in a case where the first concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the first concave portion is formed as a hollow placement groove;
in a case where the second concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the second concave portion is formed as a hollow relief groove; and
in a case where the first concave portion and the second concave portion together form the receiving area for the display module body, the first concave portion is formed as the hollow placement groove, and the second concave portion is formed as the hollow relief groove.

5. The jig according to claim 2 , further comprising a first limit structure and a second limit structure, the first limit structure is disposed on the first flat portion of the bottom plate, the second limit structure is disposed on the second flat portion of the cover plate, and the first limit structure and the second limit structure are configured to fit with each other.

6. The jig according to claim 2 , wherein the bottom plate and the cover plate are rotatably connected with each other.

7. The jig according to claim 6 , wherein the bottom plate and the cover plate are rotatably connected with each other by a coil.

8. The jig according to claim 1 , wherein
in a case where the first concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the first concave portion is formed as a placement groove;
in a case where the second concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the second concave portion is formed as a relief groove; and
in a case where the first concave portion and the second concave portion together form the receiving area for the display module body, the first concave portion is formed as the placement groove, and the second concave portion is formed as the relief groove.

9. The jig according to claim 8 , further comprising a first limit structure and a second limit structure, the first limit structure is disposed on the first flat portion of the bottom plate, the second limit structure is disposed on the second flat portion of the cover plate, and the first limit structure and the second limit structure are configured to fit with each other.

10. The jig according to claim 9 , wherein the first limit structure is a limit post disposed on the first flat portion of the bottom plate, and the second limit structure is a limit hole penetrating through the cover plate.

11. The jig according to claim 10 , wherein the first limit structure is a positioning pin, and the second limit structure is a positioning slot which is configured to fit with the positioning pin.

12. The jig according to claim 1 , wherein
in a case where the first concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the first concave portion is formed as a hollow placement groove;
in a case where the second concave portion selected from the group consisting of the first concave portion and the second concave portion forms the receiving area for the display module body, the second concave portion is formed as a hollow relief groove; and
in a case where the first concave portion and the second concave portion together form the receiving area for the display module body, the first concave portion is formed as the hollow placement groove, and the second concave portion is formed as the hollow relief groove.
