Abstract

The present disclosure relates to a device for detecting a liquid crystal module and a method for detecting the quantity of liquid crystal. The method includes a cover for fixedly accommodating the liquid crystal module. An accommodation space for accommodating collision units is formed between the liquid crystal module and the cover, the collision units being connected to the top wall of the cover through elastic members. The collision units are spaced from the liquid crystal module in a certain distance in a static status, and collide with a panel of the liquid crystal module through vibration of the cover in the vertical direction during detection. The device for detecting a liquid crystal module improves the detection efficiency.

First claim

The invention claimed is:

1. A device for detecting a quantity of liquid crystal of a liquid crystal module, including a horizontally-arranged covered for fixedly accommodating the liquid crystal module, wherein an accommodation space for accommodating collision units is formed between the liquid crystal module and the cover, the collision units being connected to the top wall of the cover through elastic members, and wherein the collision units are spaced from the liquid crystal module at a certain distance in a static status, and collide with any predetermined/required position of a panel of the liquid crystal module through vibration of the cover in the vertical direction during detection, and wherein the elastic members are connected to the top wall of the cover in such a manner that the position of each elastic member can be changed, wherein in the static status, the distance between the collision unit and the panel of the liquid crystal module is 2 to 3 times the height of the collision unit.

2. The device according to claim 1 , wherein the elastic member is a spring.

3. The device according to claim 1 , wherein the surface of each collision unit that can contact the panel of the liquid crystal module is configured as spherical surface.

4. The device according to claim 3 , wherein each collision unit is designed as a ball.

5. The device according to claim 4 , wherein the cover includes side walls extending downwards from the top wall, and a connector for fixing the liquid crystal module is arranged on each side wall.

6. The device according to claim 5 , wherein the device further includes a vibrating platform for applying vertical vibration, and the lower end of each side wall is connected with the vibrating platform through a fixing member.

7. A method for detecting the quantity of liquid crystal with the device according to claim 1 , including the following steps:
(a) providing a cover, and arranging a plurality of collision units connected with the top wall of the cover through elastic members respectively in the cover;
(b) fixedly accommodating a liquid crystal module to be detected in the cover in such a manner that the liquid crystal module is spaced from the collision units in a certain distance, a panel of the liquid crystal module facing the collision units;
(c) vertically vibrating the cover so that the collision units collide with the panel of the liquid crystal module; and
(d) stopping vibration of the cover, and taking the liquid crystal module out for analyzing.

8. The method according to claim 7 , wherein after step (d), the elastic members are moved, and then the cover is vertically vibrated again to collide with other positions of the panel of the liquid crystal module.
