Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended to fill a liquid in a filling jig for sucking and filling a liquid in a closed container, particularly in an empty cell for LCD (liquid crystal element). The present invention relates to a suitable liquid injection jig.

[Conventional technology]

FIG. 7 is a structural view showing a conventional liquid injection jig of this type, and shows a case where liquid crystal is injected into an LCD empty cell. In the figure, 1 is a storage container filled with liquid crystal 2 and 3
Is an empty cell for LCD, which is a closed type injection container.
Is provided.

When enclosing the liquid crystal 2 in the empty cell 3, first, both the storage container 1 and the empty cell 3 are put in a vacuum container (not shown) and set at an appropriate distance. In this state, the inside of the vacuum container is evacuated to make the inside of the empty cell 3 into a vacuum, and the injection port 4 of the empty cell 3 is directly immersed in the liquid crystal 2 in the storage container 1 as shown in FIG. After that, the inside of the vacuum container is returned to the original atmospheric pressure, so that the liquid crystal 2 is sucked into the empty cell 3 through the injection port 4. After that,
The storage container 1 and the empty cell 3 are separated, and the injection of the liquid crystal 2 is completed.

[Problems to be solved by the invention]

The conventional liquid injection jig has the above-mentioned structure, and the injection port 4 of the closed type injection container CLCD empty cell 3) is immersed in the liquid (liquid crystal 2) at the time of injection. When the injection container is pulled up from the liquid, the liquid adheres to the vicinity of the injection port 4 as shown in FIG. 9 and the loss of the injected liquid is large. In particular, the smaller the filling container, the smaller the difference between the filling amount and the adhering amount of liquid in the container,
Increased liquid loss.

The present invention has been made in view of such problems, and provides an injection jig in which the amount of liquid adhered is reduced and the loss of liquid is reduced.

[Means for solving problems]

The liquid pouring jig of this invention is a porous body for a base, which is installed in a pouring liquid storage container and has a groove at the upper part, and a replaceable member which is fitted into the groove and mounted to abut the pouring port of the pouring container. And a porous body for injection are provided.

[Action]

The porous body for base is set in a storage container filled with the injection liquid, and the porous body for injection is fitted and mounted in the groove provided in the upper portion thereof. In this state, when the injection port of the closed type injection container is brought into contact with the injection porous body, the liquid in the storage container is sucked into the injection container from the injection port through the porous body. At this time, since the injection port is only in contact with the injection porous body, the liquid does not adhere to the vicinity of the injection port after the injection is completed, and the liquid loss is small.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a structural view showing a liquid crystal injection jig according to the present invention. In the figure, 11 is an LCD which is a closed type injection container.
An empty cell, 12 is an inlet thereof, and 13 is a storage container, and liquid crystal 14 is filled therein. Reference numeral 15 is a porous body for a base installed in the storage container 13, and a groove 16 is provided on the upper portion thereof. Reference numeral 17 designates a replaceable porous body for injection which is fitted and mounted in the groove 16.

As in the conventional case, when injecting the liquid crystal 14, first, as shown in FIG. 1, an LCD empty cell 1 is placed in a vacuum container (not shown).
1 and the storage container 13 having the base porous body 17 mounted thereon are opposed to each other with a predetermined distance, and the inside of the vacuum container is evacuated.
Then, the air in the empty cell 11 is evacuated and the porous body for injection 1
7 and the liquid crystal 14 in the storage container 13 is defoamed. After that, as shown in FIG. 2, the porous body 17 for injection and the empty cell 1
The injection port 12 of No. 1 is contacted, and the atmosphere in the vacuum container is returned to atmospheric pressure in this state. As a result, the liquid crystal 14 in the storage container 13 is injected into the empty cell 11 through the injection port 12 through both the porous bodies 15 and 17.

FIG. 3 is an exploded perspective view showing the base and injection porous bodies 15, 17 in an enlarged manner. The base porous body 15 is
For example, it is made of porous glass for filters, magnetism, pottery, sintered metal filters, sponge, etc., and the porous body for injection 17 is also made of the same material, but is made of a soft porous material to facilitate injection. A desirable material is, for example, hydrophilic plastic porous sintered body, cellulose sponge,
PVA sponge or siliglass cloth can be used.

Further, FIG. 4 shows an injection jig in the case of multiple injection in which a plurality of LCD empty cells are simultaneously injected. That is, a plurality of (four in the figure) grooves 16 are provided in the base porous body 15, and the pouring porous bodies 17 that fit into the grooves are provided in the number corresponding to the number of the grooves 16. FIG. 5 shows a state at the time of starting the injection, in which each injection porous body 17 and the injection container 11 are provided.
The liquid crystal 14 is sucked into the injection container 11 in this state. In this case, the jigs shown in FIG. 3 may be used side by side, but in order to obtain positional accuracy, the jigs for holding the jigs in the base porous body 15 in accordance with the pitch of the inlets 12 of the empty cells 11 to be arranged. Forming the groove 16 of
It is desirable to insert the porous body 17 for injection into the groove 16 for use.

Here, at the time of injection, since the injection port 12 of the empty cell 11 is only in contact with the injection porous body 17, the liquid crystal 14 does not adhere to the vicinity of the injection port as in the conventional case, and the loss of the liquid crystal 14 occurs. Can be small. When the pouring body 17 becomes unusable due to deformation or damage, the expensive liquid crystal 14 is stored in the storage container 13 or the like by passing it between the squeezing rollers 18 as shown in FIG. 6, for example. Can be collected. At this time, the injecting jig is divided into the injecting jig for the base and the injecting jig, the injecting porous body 17 for injecting the liquid crystal 14 is easy and the conversion cost is low, and the porous body 15 for the base is semipermanent. Can be used for any purpose.

Although the liquid crystal injection jig is described in the above embodiment,
The present invention can be applied to other applications, and is particularly suitable for injecting a liquid into a closed type injection container having a gap as small as possible.

[Effect of device]

As described above, according to the present invention, the base porous body having the groove formed on the upper portion is installed in the liquid storage container, and the replaceable pouring porous body is fitted and mounted in the groove. Since the liquid is sucked into the closed type injection container through these porous bodies, the amount of the liquid adhering to the vicinity of the injection port during injection is extremely reduced, and the liquid loss is reduced with a simple structure. The effect is that you can.
