Description

Liquid crystal dispenser for liquid crystal dispenser and liquid crystal dispenser including the same {APPARATUS FOR SPRAYING LIQUID CRYSTAL AND LC DISPENSER INCLUDING THE SAME}

The present invention relates to a liquid crystal dispenser, and more particularly, to a liquid crystal spraying device for dropping a liquid crystal on a substrate and a liquid crystal dispenser having the same.

In general, LCDs include a lower substrate including drive elements such as transistors in a plate glass, an upper substrate provided with a color filter layer, etc. in a plate glass, a sealing material for bonding the lower substrate and the upper substrate, and a lower substrate. It comprises a liquid crystal layer filled between the upper substrate. Such LCDs drive liquid crystal molecules of the liquid crystal layer by driving elements formed on the lower substrate, and display information by controlling the amount of light passing through the liquid crystal layer by driving the liquid crystal molecules.

 As one of the LCD manufacturing methods, a substrate is manufactured by forming driving elements in a glass having a predetermined size, and another substrate is manufactured by forming a color filter layer or the like on another glass. Then, a sealing material is applied to one of the two substrates in a pattern of a predetermined shape, liquid crystal drops are dropped in a pattern in which dots are arranged in an inner region of the sealing material, and then the two substrates are bonded. At this time, as the two substrates are bonded together, the patterned liquid crystal droplets form a liquid crystal layer between the two substrates. Then, by cutting the mother glass bonded to the two substrates to produce a unit liquid crystal panel constituting the LCD. An area constituting the unit liquid crystal panel in the substrate is called a unit panel area.

In this case, the distance between the two substrates constituting the mother glass is very small in micrometers, and the thickness of the liquid crystal layer filled between the two substrates is also very thin in micrometers.

This manufacturing method proceeds in a manufacturing line in which manufacturing equipment having respective functions is arranged. Among the manufacturing equipments, a process of dropping a liquid crystal and a process of discharging a sealing material are performed by a dispenser.

In the liquid crystal dispenser in which a liquid crystal is loaded, a process of dispensing liquid crystal is typically described. First, a substrate on which the liquid crystal is to be dropped is placed on the stage of the base frame. Then, the liquid crystal dropping device located on the stage moves according to the previously input pattern, and the liquid crystal is dropped at the nozzle of the liquid crystal dropping device.

The liquid crystal dropping device moves along a column installed on the base frame. The columns are formed in a bent shape, and both ends thereof are coupled to the base frame so as to be movable in one direction.

However, in order for the liquid crystal to free fall from the nozzle, a weight of about 1 mg to 5 mg is required. Therefore, in the conventional liquid crystal dispenser, about 1 mg to 5 mg of liquid crystal is discharged from the nozzle. However, in the related art, a thickness difference of the liquid crystal layer occurs between a region where a liquid crystal having a weight of about 1 mg to 5 mg is actually dropped and a region where the dropped liquid crystal is reflowed. Since the thickness difference of the liquid crystal layer makes the path of light passing through the liquid crystal layer different, as a result, a stain occurs on the screen when the product is applied, resulting in a defect of the product.

In addition, the liquid crystal having a weight of 1 mg to 5 mg is not atomized in the dropping process, but is dropped into a drop mass, and the shape of the liquid crystal droplet is instantaneously deformed by an instant impact when the dropped liquid crystal droplets collide with the substrate. When the shape of the liquid crystal droplets is momentarily deformed, small pieces of liquid crystal droplets fall off from the liquid crystal droplets and fall to a point other than the point where the liquid crystal droplets are dropped. Therefore, when the liquid crystal droplets fall to the point where the sealing material is bonded, there is a problem that the substrates are not well bonded during the mother glass bonding process. In addition, when the fragments of the liquid crystal drops out of the unit panel region, there is a problem that the total amount of the liquid crystal dropped in the unit panel region is smaller than the preset amount.

On the other hand, since the liquid crystal is added dropwise to the substrate by 1mg to 5mg, in order to drop all the liquid crystal required for the unit panel region, first, the liquid crystal is dropped by 1mg to 5mg at one point. Then, the liquid crystal dropping device is transferred to a neighboring position along the column. Then, the liquid crystal dropping device drops the liquid crystal by 1 mg to 5 mg.

That is, instead of dropping the liquid crystal while the liquid crystal dropping device is continuously transferred to drop the liquid crystal, the transfer of the liquid crystal dropping device and the liquid crystal dropping are alternately made. As a result, there is a problem that the time for dispensing the liquid crystal in the unit panel region becomes long.

SUMMARY OF THE INVENTION The present invention has been made to solve various problems including the above problems, and an object of the present invention is to provide a liquid crystal spraying device and a liquid crystal dispenser in which a liquid crystal is accurately positioned inside the unit panel region.

Another object of the present invention is to provide a liquid crystal spraying device and a liquid crystal dispenser which can prevent the occurrence of spots upon dropping of the liquid crystal.

Still another object of the present invention is to provide a liquid crystal dispenser having a structure that can shorten the time for dispensing the liquid crystal.

The liquid crystal injection device for liquid crystal dispensers of this invention for solving the said subject includes a liquid crystal vibration nozzle, a gas nozzle, and a vibration means.

The vibrating nozzle for liquid crystal includes a liquid crystal suction port, a liquid crystal injection port, and a liquid crystal connector. The liquid crystal suction port receives a certain amount of liquid crystal. The liquid crystal jet port ejects liquid crystal from the liquid crystal suction port. The liquid crystal connector is connected to the liquid crystal suction port and the liquid crystal injection port so as to vibrate to atomize the liquid crystal.

The gas nozzle includes a gas discharge port formed to surround the liquid crystal injection port.

The vibration means supplies vibration energy to the liquid crystal connector.

In this case, the vibrating means may further include a piezoelectric element coupled to the liquid crystal connector and vibrating the liquid crystal connector, and a power supply device for supplying power to the piezoelectric element.

In addition, the liquid crystal connector tube is made of a piezoelectric element material, the vibration means may include a power supply for supplying power to the liquid crystal connector tube.

The gas nozzle may further include a gas inlet and a gas diffusion chamber. The gas inlet receives gas from the gas tank. The gas diffusion chamber is interposed between the gas suction port and the gas discharge port, and temporarily stores the gas sucked from the gas suction port and supplies the gas to the gas discharge port.

In this case, the gas discharge port may be disposed on the same axis as the liquid crystal injection port, so that the gas discharged therefrom does not deviate from the proper range of the liquid crystal injected from the liquid crystal injection port.

On the other hand, the liquid crystal dispenser according to the embodiment in another aspect of the present invention includes a base frame, a column, a liquid crystal injection device, and a control device. The base frame supports the substrate having at least one unit panel region. A column is mounted to the base frame to cross the upper side of the substrate supported on the base frame. The liquid crystal ejection apparatus is mounted to be horizontally movable along the column, and injects a predetermined amount of liquid crystal onto the unit panel region of the substrate. The controller controls the horizontal movement speed of the liquid crystal injector and the amount of liquid crystal supplied to the liquid crystal suction port.

In this case, the controller needs to control the liquid crystal spraying device to continuously transport the liquid crystal spraying device from at least one end of the unit panel region of the substrate to the other end, and to dispense at the time of the transfer. Control to continuously eject the liquid crystal.

According to the present invention, the liquid crystal is atomized from the vibrating nozzle for liquid crystal of the liquid crystal injector and sprayed onto the substrate as if it is sprayed, so that the thickness difference between the region where the liquid crystal is sprayed and the region where the liquid crystal is reflowed is minimized. Accordingly, the probability of spot unevenness is lowered. This results in the improvement of the display quality of the panel.

In addition, the gas acts as an air curtain around the liquid crystal to be injected, thereby preventing the liquid crystal from falling within a predetermined region and out of the region. Accordingly, the substrates adhere well during the mother glass bonding process, and the total amount of the liquid crystal dropped in the unit panel region is equal to a preset amount.

In addition, by continuously conveying the liquid crystal injector and simultaneously dispensing the liquid crystal, the total liquid crystal dispensing time is shortened and productivity is improved.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 illustrate a configuration of a liquid crystal injection apparatus 100 according to an embodiment of the present invention. In FIG. 1 and FIG. 2, the liquid crystal injection device 100 includes a liquid crystal vibration nozzle 110, a gas nozzle 120, and a vibration means 130.

The vibrating nozzle 110 for the liquid crystal includes a liquid crystal suction port 111, a liquid crystal injection port 113, and a liquid crystal connector tube 115. The liquid crystal suction port 111 receives a certain amount of liquid crystal. The liquid crystal jet port 113 injects the liquid crystal from the liquid crystal suction port 111. The liquid crystal connector tube 115 connects between the liquid crystal suction port 111 and the liquid crystal injection port 113 so as to vibrate to atomize the liquid crystal L.

The vibration means 130 controls supply of vibration energy to the liquid crystal connector tube 115. When the liquid crystal connection tube 115 vibrates, the vibration is transmitted to the liquid crystal L passing therethrough, thereby atomizing the liquid crystal.

In this case, the vibration means 130 may include a piezoelectric element 131 and a power supply device 133.

The piezoelectric element 131 is an element that receives electrical energy and changes it into vibration energy. That is, when the piezoelectric element 131 is coupled to the liquid crystal connector tube 115, and a voltage is applied according to the natural frequency of the piezoelectric element 131, the piezoelectric element 131 and the liquid crystal connector tube coupled thereto ( 115 vibrates, and thus vibration energy is transmitted to the liquid crystal L passing through the liquid crystal connector tube 115.

The power supply 133 serves to supply a voltage to the piezoelectric element 131.

In this case, as the frequency of the power supplied to the piezoelectric element 131 through the power supply device 133 increases, the liquid crystal connector tube 115 vibrates faster. The liquid crystal connection tube 115 preferably vibrates at a frequency corresponding to ultrasonic waves (20 KHz or more).

The liquid crystal connector tube 115 of the vibrating nozzle 110 for liquid crystal may be accommodated by the case 140. In this case, a coupling member 146 is interposed between the liquid crystal connector tube 115 and the case 140 to prevent the vibration of the liquid crystal connector tube 115 from being transmitted to the case 140. Of course, the suction member 146 may be omitted. In this case, the case 140 also vibrates together. The suction member 146 may be a material such as a rubber material that can absorb vibration.

On the other hand, the liquid crystal connector 115 itself may be made of a piezoelectric element 131, in which case the power supply 133 supplies a voltage to the liquid crystal connector 115 so that the liquid crystal connector 115 It can vibrate.

Due to the vibration means 130, the kinetic energy of the liquid crystal (L) is increased, so that the liquid crystal (L) of 0.1 mg to 0.8 mg, which is a weight that is conventionally formed at the end of the nozzle, may also fall from the liquid crystal injection port (113). You can do that. In this case, it is preferable that the liquid crystal injection port 113 is also vibrated by the vibration means 130. In this case, the liquid crystal suction port 111, the liquid crystal connector tube 115, and the liquid crystal injection hole 113 of the liquid crystal injection nozzle may be integrally formed of the piezoelectric element 131.

The gas nozzle 120 includes a gas discharge port 123. The gas discharge port 123 is formed to surround the liquid crystal injection hole 113. Therefore, the gas G is discharged along the periphery of the liquid crystal injected from the liquid crystal injection port 113 through the gas discharge port 123.

The gas G discharged from the gas nozzle 120 may perform an air curtain function. That is, the liquid crystal atomized by the vibration of the liquid crystal connector 115 is injected with a predetermined angle. However, due to the surrounding wind, the liquid crystal injector 100 moves horizontally, or more atomization than necessary, the liquid crystal may scatter in an undesired direction. In this case, the film of the gas G discharged from the gas nozzle 120 becomes a film which prevents the liquid crystals injected from the liquid crystal injection port 113 from flying out of a predetermined region.

Accordingly, the gas discharge port 123 of the gas nozzle 120 may be disposed substantially parallel to the liquid crystal injection port 113 (that is, on the same axis).

The gas nozzle 120 may further include a gas inlet 121 and a gas diffusion chamber 125. The gas inlet 121 receives gas from the gas tank 128. In this case, a gas control valve 150 may be disposed in the gas movement passage between the gas tank 128 and the gas inlet 121 to adjust the supply amount of gas.

The gas diffusion chamber 125 is interposed between the gas inlet 121 and the gas outlet 123 to temporarily store the gas sucked from the gas inlet 121 and then supply the gas inlet 123 to the gas outlet 123. . The gas diffusion chamber 125 reduces the gas pressure of the gas coming from the gas inlet 121 to reduce the speed of the gas. Accordingly, the gas has an appropriate gas pressure and can exit the gas discharge port 123.

In this case, the gas pressure of the appropriate level may mean a gas pressure that can be discharged with a sufficient amount per unit time so that the gas discharged from the gas discharge port 123 prevents the liquid crystal from going out of the proper region.

The gas pressure at an appropriate level discharged from the gas discharge port 123 may be changed according to the degree of atomization of the liquid crystal L passing through the liquid crystal connector tube 115.

If the weight of the liquid crystal that has passed through the liquid crystal connector tube 115 is atomized to an appropriate weight such that staining of, for example, 0.1 mg to 0.8 mg does not occur, the gas G discharged from the gas discharge port 123 No longer collides with the liquid crystal L, so that the liquid crystal does not need to be further atomized. This is because if the liquid crystal is atomized more than necessary, the liquid crystal droplets are more likely to be evaporated or scattered and deviated outside the proper region. In this case, the gas pressure at an appropriate level of gas refers to the degree to which the gas discharged from the gas discharge port 123 collides with the liquid crystal so that the liquid crystal can no longer be atomized. have.

On the contrary, if the weight of the liquid crystal that has passed through the liquid crystal connector tube 115 is not sufficiently atomized, at least a part of the gas collides with the liquid crystal injected from the liquid crystal injection port 113 to titrate the liquid crystal. It is necessary to atomize to the weight of the level. In this case, the appropriate gas pressure means a gas pressure such that the gas discharged from the gas discharge port 123 functions as an air curtain and a part thereof can collide with the liquid crystal to atomize it.

On the other hand, the liquid crystal vibration nozzle 110 is supplied with a predetermined amount of liquid crystal. In this case, the liquid crystal injection device 100 may further include a liquid crystal tank 168 and a metering supply device 160. The liquid crystal is stored in the liquid crystal tank 168. The fixed amount supply device 160 is interposed between the liquid crystal tank 168 and the liquid crystal vibration nozzle 110 to supply a predetermined amount of liquid crystal to the liquid crystal vibration nozzle 110.

As an example of such a fixed-quantity supply device 160, the piston pumping unit 161 has a cylinder assembly structure capable of vertical movement and rotational movement in the pumping hole as shown in Figs. In the fixed amount supply device 160, a liquid crystal inlet 163 and a liquid crystal outlet 165 are formed to communicate with a pumping hole into which the piston pumping unit 161 is inserted. The liquid crystal inlet 163 is connected to the liquid crystal tank 168 through a tube, and the liquid crystal outlet 165 is connected to the liquid crystal inlet 111 of the vibrating nozzle 110 for liquid crystal. In addition, a portion of the outer circumferential surface of the piston pumping unit 161 is formed to have a cut portion 162 formed by cutting a portion for inflow and outflow of the liquid crystal to face the liquid crystal inlet 163 or the liquid crystal outlet 165.

Referring to FIGS. 1 and 2, the process from the liquid crystal tank 168 to the liquid crystal injecting device L and flowing out of the liquid crystal injection device 100 will be described in detail. As shown in FIG. 1, the piston 167 is rotated such that the cut portion 162 of the piston pumping portion 161 faces the liquid crystal inlet 163 of the cylinder. In this state, the piston drive is controlled to move the piston 167 upward. As the piston 167 moves upward, the liquid crystal suction space formed between the end surface of the piston pumping portion 161 and the pumping hole increases, and the liquid crystal L in the liquid crystal tank 168 is separated by the pressure difference outside the space. It is introduced into the liquid crystal suction space through the inlet 163.

Afterwards, the piston driving unit is controlled to rotate the piston 167 so that the cut portion 162 of the piston pumping unit 161 may face the liquid crystal outlet 165 of the cylinder, as shown in FIG. 2. After that, the piston 167, which has been raised, is moved downward. As the liquid crystal suction space becomes smaller, the liquid crystal filled in the space is supplied to the liquid crystal vibration nozzle 110 through the liquid crystal outlet 165.

As described above, the liquid crystal L filled in the liquid crystal tank 168 is supplied to the vibrating nozzle 110 for liquid crystal of the quantitative liquid through the quantitative supply device 160.

According to the embodiment of the present invention as described above, the liquid crystal is atomized from the vibrating nozzle for the liquid crystal of the liquid crystal spraying apparatus 100 and sprayed onto the substrate, whereby the difference in thickness between the region where the liquid crystal is sprayed and the region where the liquid crystal is reflowed Minimum. Accordingly, the probability of spot unevenness is lowered. This results in the improvement of the display quality of the panel.

In addition, the gas acts as an air curtain around the liquid crystal to be injected, thereby preventing the liquid crystal from falling within a predetermined region and out of the region. Accordingly, the substrates adhere well during the mother substrate bonding process, and the total amount of the liquid crystal dropped in the unit panel region is equal to a preset amount.

3 illustrates a liquid crystal dispenser according to a preferred embodiment of the present invention.

In this case, the column 500 is positioned to cross the stage 300. The stage 300 moves in one direction on the fixed table 600 installed on the base frame 200. The direction in which the stage 300 moves is perpendicular to the column 500. Meanwhile, the liquid crystal dispenser 1 may further include a weighing apparatus 700 for measuring the weight of the liquid crystal.

1 to 3, the controller controls the horizontal movement speed of the liquid crystal injection device 100 and the amount of liquid crystal supplied to the liquid crystal suction port 111. The control device may include a transfer control unit for controlling the transfer of the liquid crystal injection apparatus 100 along the column, and a fluid control unit for controlling the amount of liquid crystal supplied to the liquid crystal nozzle. The transfer control unit and the fluid control unit may operate in conjunction with each other.

In this case, the controller controls the liquid crystal injector 100 to continuously transport the liquid crystal injector 100 from at least one end of the unit panel region of the substrate P to the other end, It can control so that the liquid crystal which needs to be dispensed at the time of conveyance may be sprayed continuously.

According to the present invention, it is not necessary to drop the liquid crystal intermittently. In other words, according to the present invention, the liquid crystals are not dropped drop by drop, but are atomized and sprayed in a spray form, so that all the necessary amount can be continuously sprayed on the unit panel region.

Hereinafter, the liquid crystal injection method that can be adopted in the liquid crystal dispenser 1 of the present invention will be described in detail with reference to FIGS. 4A to 4D and FIG. 1.

In addition, the liquid crystal connector tube 115 of the vibrating nozzle for liquid crystal vibrates by the power supply device 133 to atomize the liquid crystal (L) through the liquid crystal connector tube 115. In this case, the gas is also continuously discharged through the gas discharge port 123 to prevent the liquid crystal L from being sprayed outside the predetermined area.
