Description

Sealing equipment for liquid crystal panel {Equipment for sealing a seal for a liquid crystal pannel}

The present invention relates to a sealing device for a liquid crystal panel for sealing a liquid crystal injected into the liquid crystal panel, and more particularly, an aligner dedicated to aligning the liquid crystal panel is further disposed on the surface of the pusher. The present invention relates to a sealing device for a liquid crystal panel, which enables automation of a cassette mounting process of an entire liquid crystal panel by allowing them to form a natural alignment structure with the communication slits of the cover without forming their gaps tightly.

Recently, as the modern society becomes information socialized, the importance of the liquid crystal display device, which is one of the information display devices, is gradually increasing. In particular, the liquid crystal display device due to its advantages such as small size, light weight, low power consumption, etc. As an alternative means to overcome the shortcomings of the CRT (Cathode Ray Tube), the use area is gradually expanding.

In general, such a liquid crystal display device has a structure in which a liquid crystal panel in which an upper substrate and a lower substrate are combined into one is inserted into a mold frame, and in this case, a liquid and solid intermediate property is formed between upper and lower substrates of the liquid crystal panel. It is common to inject liquid crystals, and these liquid crystals generate dynamic scattering by voltages applied from the outside, and promote the modulation of light transmitted from the inside of the liquid crystal panel to the outside, so that the liquid crystal panel has an image information display function. It is induced to perform well.

On the other hand, in the production line, in order to inject the above-mentioned liquid crystal between the upper and lower substrates of the liquid crystal panel, one of the two substrates, for example, a part of the upper substrate, a so-called "silk draw process" is performed, The position to be injected should be defined in advance, and after this seal drawing process, a so-called "sealing sealing process" should be carried out to prevent the problem that the injected liquid crystal leaks to the outside in advance.

Among these processes, in particular, the "sealing process" is increasingly important in terms of preventing the leakage of liquid crystals, and therefore, a seal for a liquid crystal panel dedicated to such a "sealing process" in a conventional production line. An encapsulation facility is provided, thereby inducing the progress of a stable "sealing process", thereby preventing inadvertent process accidents caused by external leakage of the liquid crystal.

In this case, the sealing device for a liquid crystal panel usually includes a combination of a chamber in which a constant storage space is defined, a cover disposed above the chamber, and a pusher disposed below the chamber.

In a conventional production line, a series of seal sealing processes are performed using the seal device for liquid crystal panels. In detail, the production line first loads a cassette equipped with a plurality of liquid crystal panels into a storage space of a chamber. Thereafter, the pusher disposed under the chamber is driven to push up the liquid crystal panel mounted on the cassette.

At this time, since the cover is disposed on the upper side of the chamber, and the communication slits of a predetermined size are formed in the cover, the liquid crystal panels pushed up by the pushing operation of the pusher eventually have their edges through the communication slits of the cover. It forms a structure that is exposed to the outside.

In this state, when supplying a certain amount of pressurized air to the storage space of the chamber described above, each liquid crystal panel is strongly pressed by the pressing force of the pressurized air supplied, and finally, between the upper and lower substrates of each liquid crystal panel Part of the liquid crystal is pushed out through the edge portion of the liquid crystal panel exposed to the outside of the cover.

At this time, the production line wipes off the liquid crystal pushed out through the edge portion of the liquid crystal panel, and then tightly seals the edge portion of the liquid crystal panel using, for example, an ultraviolet curing agent, thereby preventing external leakage of the liquid crystal.

As described above, the liquid crystal panel pushed up by the pushing operation of the pusher forms a structure in which its edge portion is exposed to the outside through the communication slits of the cover, in which case, the liquid crystal panels inserted into the slots of the cassette If the alignment of the cover communication slits with the cover is slightly misaligned, the liquid crystal panels pushed up by the pushing operation of the pusher do not pass through the communication slits of the cover and cause a problem of colliding with the bottom surface formed between the communication slits of the cover. . In this case, the liquid crystal panel suffers a certain amount of damage to its edge surface by the impact of the impact on the bottom surface of the cover, after all, even if the liquid crystal panel in the production line does not cause any problems in the pretreatment process, such edge damage For this reason, the liquid crystal panel has no choice but to be discarded.

Therefore, in the conventional production line, various efforts have been made to prevent such damage of the edge of the liquid crystal panel.

For example, in a conventional production line, the liquid crystal panel is inserted into each slot in a state in which the slots of the cassette are closely arranged to correspond to the communication slits of the cover, whereby the liquid crystal panel fitted into the slots is the communication slit of the cover. By maintaining an accurate alignment with the field, even if the pusher is pushed, the liquid crystal panel does not cause a problem such as colliding with the bottom surface of the cover.

As such, when the liquid crystal panel is densely mounted in the slots of the cassette according to the interval of the cover communication slit, the alignment state of the liquid crystal panel and the cover communication slit can be maintained accurately, and the damage of the liquid crystal panel that is not predicted in the production line This prevented advantage can be obtained, but in this case, since the liquid crystal panel must be inserted very tightly into the slots of the cassette, the production line of the liquid crystal panel cassette is carried out through an automated facility such as a robot arm. You have to take a problem that can't proceed quickly. This is because it is very difficult to develop a robot arm with the sophistication enough to insert the liquid crystal panel into the slots of the cassette at the present technology level.

As a result, in the conventional production line, the cassette mounting process of the entire liquid crystal panel has to be inconvenient to be carried out manually by the operator.

As such, when the cassette mounting process of the liquid crystal panel is performed by the manual labor of the operator, the overall process is inevitably slowed, so that the production line has a problem that the product production efficiency is significantly reduced.

Of course, in order to prevent such a problem in advance, the liquid crystal panel may be inserted into a wider pitch by widening the gap between the slots of the cassette. Thus, when the liquid crystal panel is mounted in the slots of the cassette at a wide pitch, Since an unexpected collision between the covers occurs and damage to the liquid crystal panel, the production line is not aware of the above problems, but has not prepared a specific countermeasure.

Accordingly, an object of the present invention is to partially improve the shape of the pusher that pushes the liquid crystal panel toward the cover, so that a collision between the liquid crystal panel and the bottom of the cover can be prevented in advance while the liquid crystal panel is inserted at a wide pitch between the slots of the cassette. To induce it.

Another object of the present invention is to improve the shape of the pusher so that the alignment between the liquid crystal panels and the cover communication slits can be made naturally without tightly forming the gaps of the liquid crystal panels, so that the cassette mounting process of the liquid crystal panel is, for example, It is to induce automatic progress through automation equipment such as robot arms.

Still another object of the present invention is to significantly improve overall product production efficiency by automating the cassette mounting process of the liquid crystal panel.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

2 is an enlarged view illustrating main parts of FIG. 1;

Figure 3 is an exemplary view showing a seal sealing facility according to another embodiment of the present invention.

4 is an enlarged view illustrating main parts of FIG. 3;

The seal encapsulation facility for a liquid crystal panel according to the present invention for achieving the above object is defined a storage space of a predetermined size, the chamber for storing a cassette equipped with a plurality of liquid crystal panels using the storage space, and the chamber It is disposed on the lower side of the pusher, which corresponds to the bottom surface of the cassette, and is driven up and down by an external force to individually push up the liquid crystal panel mounted on the cassette, and a plurality of communication slits. It is disposed on the upper side of the chamber so as to face the cover, and covers the upper portion of the chamber to seal the storage space, and when the liquid crystal panels are pushed up individually by the operation of the pusher, the cover exposes the liquid crystal panels to the outside through communication slits. Is made up of a combination.

At this time, a plurality of aligners are arranged on the surface of the pusher in contact with the liquid crystal panel to align the liquid crystal panels according to the communication slit.

In the case of the present invention, as described above, since a plurality of aligners dedicated to aligning the liquid crystal panels to the communication slit are further arranged on the surface of the pusher, in the production line, The alignment between the liquid crystal panels and the communication slits can be naturally obtained without closely disposing the gaps of the liquid crystal panels. Consequently, the cassette mounting process of the liquid crystal panels can be smoothly performed through an automated tool such as a robot arm. You can.

As such, when the cassette mounting process of the liquid crystal panels is automated, since the production speed of the product is improved, the production line can obtain the effect of maximizing the overall product production efficiency.

Hereinafter, the sealing device for a liquid crystal panel according to the present invention with reference to the accompanying drawings in more detail.

As shown in FIG. 1, the seal encapsulation facility 100 according to the present invention is largely provided with a chamber 101, a pusher 104 disposed under the chamber 101, a pusher 104, It consists of a combination of covers 105 arranged on the upper side of the chamber 101 so as to face each other.

In this case, a storage space having a predetermined size is defined inside the chamber 101, and a cassette 20 mounted with a plurality of liquid crystal panels 1 is stored in the storage space. In this case, the front and rear frames 21 of the cassette are provided with slots 22 spaced apart from each other at regular intervals, and the liquid crystal panels 1 are separately inserted into each of the slots 22. .

Here, as shown in the figure, the above-described pusher 104 is composed of a bottom plate 102 and a combination of the support rods 103 which vertically support the bottom plate 102, for example, A portion of the pusher 104, for example the bottom plate 102 of the pusher 104, has a structure corresponding to the bottom surface 23 of the cassette 20 mentioned above.

In this state, when an external force is applied to another part of the pusher 104, for example, the support rod 103 of the pusher 104, the support rod 103 is driven up and down by the applied external force. The bottom plate 102 is also driven up and down by up and down driving.

In this case, as described above, the bottom plate 102 has a structure corresponding to the bottom surface 23 of the cassette 20, and the bottom surface 23 of the cassette 20 has a lower side of the liquid crystal panel 1. Because the edges are exposed, when the bottom plate 102 moves up and down by the above action, the liquid crystal panels 1 mounted on the cassette 20 are moved up by the operation of the bottom plate 102. Move down.

For example, when the supporting rod 103 proceeds in an ascending operation by an external force, the bottom plate 102 also proceeds in an ascending operation. As a result, the liquid crystal panels 1 mounted on the cassette 20 are connected to this bottom plate ( It is pushed up individually by the ascending operation of 102).

Meanwhile, the cover 105 covers the upper portion of the chamber 101 so that the storage space in which the cassette 20 is accommodated is sealed from the outside air. In this case, the liquid crystal panels mounted on the cassette 20 are covered. When (1) is pushed upward by the above-mentioned ascending operation of the pusher 104, the cover 105 opens the individual liquid crystal panels 1 through the communication slits 106 in communication with its surface. Naturally exposed to the outside.

In this case, as shown in FIG. 2, the liquid crystal panels 1 may be covered on a part of the surface of the pusher 104, for example, the bottom plate 102, which is in contact with the liquid crystal panels 1. A plurality of aligners 16 are arranged to align with the communication slits 106 of.

The aligners 16 are formed of a combination of the first and second protrusions 10 and 15 corresponding to one of the liquid crystal panels 1 as described above. The second protrusions 10 and 15 stand on the surface of the pusher 104 to form a structure facing each other. In this state, the first protrusions 10 correspond to one-to-one correspondence with the corresponding liquid crystal panel 1. One side of, for example, forms a structure surrounding the left side, and the second protrusion 15 forms a structure surrounding the other side, for example, the right side of the liquid crystal panel 1 corresponding to one-to-one correspondence with itself.

In this case, the interval between the upper portions 11 and 13 of the first and second protrusions 10 and 15 is wider than the thickness P1 of the liquid crystal panel 1, and the first and second protrusions 10 and 15 are provided. The interval between the lower portions 12, 14 of the N-Y is maintained at a value corresponding to the communication interval P2 of the communication slit 106 described above, for example, P3.

The arrangement of these aligners constitutes a gist of the present invention. Of course, the aligners are not disposed at all in the conventional sealing device for liquid crystal panels.

In the conventional case, since an aligner dedicated to aligning the liquid crystal panel is not disposed separately, when the liquid crystal panel is mounted in the cassette as a countermeasure to prevent damage to the liquid crystal panel, the liquid crystal panels may be arranged in the cover. It was mounted closely at intervals.

However, in this case, although the advantage of preventing damage to the liquid crystal panel can be obtained in advance, the liquid crystal panel must be closely inserted into each slot of the cassette. For example, it was necessary to take the problem that can not proceed quickly through the automation equipment such as robot arms.

In this case, the cassette mounting process of the liquid crystal panel has no choice but to rely solely on the manual labor of the operator, which leads to a serious problem of slowing down the overall process and significantly lowering the product production efficiency.

In contrast, in the present invention, as described above, a plurality of aligners 16 dedicated to the alignment of the liquid crystal panels 1 with the communication slits 106 on the surface of the pusher 104. Because of this further arrangement, when the present invention is achieved, the alignment between the liquid crystal panels 1 and the communication slits 106 is naturally arranged in the production line without closely disposing the gaps of the liquid crystal panels 1. As a result, the mounting process of the cassette 20 of the liquid crystal panels 1 can be smoothly performed through, for example, an automation tool such as a robot arm.

As such, when the cassette mounting process of the liquid crystal panels 1 is automated, since the production speed of the product is improved, the production line can obtain the effect of maximizing the production efficiency of the entire product.

Hereinafter, the operation of the seal device for sealing liquid crystal panel according to an embodiment of the present invention described above in detail.

First, in the production line, the liquid crystal panels 1 having completed the pretreatment process are mounted in the slots 22 of the cassette 20, and then the cassette 20 is stored in the storage space of the chamber 101.

Subsequently, in the production line, for example, a motor (not shown) is driven to induce an upward motion of the supporting rod 103 by applying an external force of a predetermined size to the supporting rod 103 mentioned above. In this case, the external force applied to the support bar 103 is transmitted to the bottom plate 102, and as a result, the bottom plate 102 also performs the same lifting operation as the support bar 103.

At this time, the bottom plate 102 has a structure corresponding to each other with the bottom surface 23 of the cassette 20, the lower edge of the liquid crystal panel 1 is exposed toward the bottom surface 23 of the cassette 20. Since the supporting rods 103 and the bottom plate 102 are moved up, the liquid crystal panels 1 mounted on the cassette 20 are pushed up toward the cover 105.

Here, the first protrusion 10 disposed on the surface of the bottom plate 102 forms a structure that surrounds the left side of the liquid crystal panel 1 corresponding to one-to-one correspondence, and the second protrusion 15 corresponds to one-to-one correspondence with itself. It forms a structure surrounding the right side of the liquid crystal panel (1). In this state, each of the individual liquid crystal panels 1 pushed up toward the cover 105 is naturally exposed to the outside through communication slits 106 communicating with the surface of the cover 106.

At this time, as described above, the interval P3 between the lower portions 12, 14 of the first and second protrusions 10, 15 is equal to the communication interval P2 of the communication slit 106 formed in the cover 105 described above. As a result, in the production line, alignment between the liquid crystal panels 1 and the communication slits 106 may be naturally obtained without closely placing the liquid crystal panels 1 inside the cassette 20.

In addition, as described above, since the interval between the upper portions 11, 13 of the first and second protrusions 10, 15 maintains a size larger than the thickness P1 of the liquid crystal panel 1, the bottom plate ( When 102 is in contact with the liquid crystal panels 1, each of the liquid crystal panels 1 may smoothly pass through the upper portions 11 and 13 of the first and second protrusions 10 and 15 to allow the first and second liquid crystal panels 1 to be in contact with the liquid crystal panels 1. The lower parts 12 and 14 of the second protrusions 10 and 15 can be easily reached.

Subsequently, the production line supplies a predetermined amount of pressurized air to the storage space of the chamber 101 mentioned above. In this case, each of the liquid crystal panels 1 is strongly pressed by the pressing force of the supplied pressurized air, and as a result, a part of the liquid crystal existing between the upper and lower substrates of the liquid crystal panels 1 is removed from the cover 105. It is pushed out through the edge portion of the liquid crystal panel 1 exposed to the outside.

Subsequently, in the production line, the liquid crystals pushed out of the liquid crystal panel 1 are wiped off, and then the edges of the liquid crystal panel 1 are tightly sealed using, for example, an ultraviolet curing agent, thereby producing a series of liquid crystal panels 1. The encapsulation process will be completed.

Meanwhile, as shown in FIG. 3, in the seal encapsulation facility 200 for a liquid crystal panel according to another embodiment of the present invention, the aligners 40 are connected one-to-one with any one of the liquid crystal panels 1 described above. It consists of a combination of the first tube body 18 and the second tube body 19, in which case the first and second tube body 10, 19 is fixed to the surface of the bottom plate 102 In other words, they are structured facing each other.

In this state, the first tube body 18 forms a structure surrounding one side, for example, the left side of the liquid crystal panel 1 corresponding to one-to-one correspondence with the second tube body 19, and the second tube body 19 corresponds to the liquid crystal corresponding to one-to-one correspondence with itself. It forms a structure surrounding the other side of the panel 1, for example, the right side.

In this case, as shown in FIG. 4, the first tube body 18 is connected to, for example, the first air supply line 107a, and the second tube body 19 is the second air supply line 107b. And the first and second air supply lines 107a and 107b are connected to the main air supply line 108.

At this time, as shown in FIG. 3 mentioned above, the cassette 30 accommodated in the storage space of the chamber 101 is different from the case of the above-described embodiment, the flame bar 31, the spacer ring 32, etc. The flame bar 31, the spacer ring 32 and the like separately separate the liquid crystal panels 1 mounted in the cassette 30, similarly to the slots 22 of the above-described embodiment. Play a role of

Subsequently, in the production line, for example, by driving a motor to apply a predetermined amount of external force to the above-mentioned support rod 103, inducing the lifting operation of the support rod 103. In this case, the external force applied to the support bar 103 is transmitted to the bottom plate 102, and as a result, the bottom plate 102 also performs the same lifting operation as the support bar 103.

At this time, the bottom plate 102 has a structure corresponding to the bottom surface 33 of the cassette 30, the lower edge of the liquid crystal panel 1 is exposed toward the bottom surface 33 of the cassette 30. Since the supporting rods 103 and the bottom plate 102 are moved up, the liquid crystal panels 1 mounted on the cassette 30 are pushed up toward the cover 105.
