Description
Technical field
The present invention relates to liquid crystal display and make processing technique field, particularly a kind of novel liquid crystal perfusion vessel.
Background technology
To be liquid crystal display becoming the technological process that in box manufacturing process, a step is important to liquid crystal filling, and it utilizes crystal-pouring machine and is undertaken pouring into by the breach of liquid crystal cell sealed plastic box bottom, and existing liquid crystal filling process can see Fig. 1, specific as follows:
(1) will wait that filling with liquid crystal sylphon 1 is placed in crystal-pouring machine cavity, vacuumizes and makes it reach setting value (being generally 1Pa), and make after a period of stabilisation to wait to fill with substantially equal with the pressure in crystal-pouring machine cavity in liquid crystal sylphon 1;
(2) by wait to fill with liquid crystal sylphon 1 and the pallet 11 filling liquid crystal 7 slowly near and contact, and just make to treat that the sealed plastic box indentation, there that filling liquid crystal sylphon 1 bottom is reserved is sealed completely by the liquid crystal 7 on pallet 3;
(3) after leaving standstill a period of time, start trickle charge gas, now liquid crystal 7 relies on capillary pulling power and waits that the pressure differential of filling with inside and outside liquid crystal sylphon 1 overcomes resistance and progresses into and wait to fill with in sylphon, after substantially filling, fast inflation returns to atmospheric pressure, the pallet 11 filling liquid crystal 7 declines and departs from, now, this treats that ullage box 1 fills liquid crystal, and perfusion completes.
Existing perfusion liquid crystal structure, is provided with liquid crystal groove 10 in pallet 11, and liquid crystal groove 10 is generally a fixed sturcture, and namely its length is fixing, and its internal groove (that is width) is also fixing, as shown in Figure 2.The vacuum cavity that can meet maximum 20 inches according to one is of a size of 600(W) × 600(D) × 550(H) and crystal-pouring machine, be suitable for liquid crystal groove 10 be of a size of ditch flute length: 30 millimeters to 40 millimeters, groove width: 5 millimeters to 15 millimeters.
In actual use, groove width determine liquid crystal pour into after groove due to surface tension can be protruding height, in order to ensure sealing effectiveness during liquid crystal filling, groove too small or cross big city go wrong, its optimum numerical value depends on sealed plastic box gap width in liquid crystal sylphon, and the design load of gap width depends on the key element such as liquid crystal size, interior pixels structure.Therefore, corresponding different in width treat perfusion liquid crystal sylphon, need the liquid crystal groove selecting width to match with it, so just, cause several specifications of liquid crystal groove different in width, such as need the liquid crystal groove preparing several different sizes such as 5mm, 8mm, 10mm, 12mm, 15mm, cause the waste that parts prepare.
Simultaneously, pour into each time and no matter have how many sylphons, in order to ensure the height of projection of liquid crystal, how long whole cell body all must fill liquid crystal, so just, cause the significant wastage of liquid crystal material, or the aged deterioration phenomenon caused is deposited in the long-time external world causing liquid crystal material, and then affects the picture quality of product.
Summary of the invention
