The present invention relates to a liquid crystal coater.

1 is a side view of a liquid crystal coater and a liquid crystal supply device.

As shown in FIG. 1, the liquid crystal coater 10 includes a main frame 100, a platform 200 provided on the main frame 100, and a coating head unit support frame 300, which are provided on the main frame 100 to enable the coating head unit support frame 300. The coating head unit 400 which moves along the length of the main frame 100 (Y-axis direction) and each nozzle having a liquid crystal droplet dripping is provided on the coating head unit support frame 300 so that each coating head unit 400 can be along The width of the main frame 100 (X-axis direction) moves.

As shown in FIG. 2, the coating head unit 400 includes a support assembly 410 movably provided on the coating head unit support frame 300, a nozzle unit 420 provided at the bottom of the support assembly 410, and a bottle holder provided on the front side of the support assembly 410. The holder 430, a liquid crystal storage device that detachably connects the bottle holder 430, and a tube 440 connected between the nozzle unit 420 and the liquid crystal storage device.

The liquid crystal storage device includes a bottle 510 that is detachably inserted into the bottle holder 430 and contains liquid crystal, and a stopper 520 that locks to the neck of the bottle 510 to close the bottle 510.

The outer surface of the neck of the bottle 510 is threaded.

The blocking member 520 has a lower vertical screw hole 521 at the bottom, an upper vertical screw hole 525 at the top, a connecting hole 522 for connecting the lower vertical screw hole 521 and the upper vertical screw hole 525, and a side edge. Horizontal hole 523. The lower vertical screw hole 521 communicates with the connecting hole 522, and the connecting hole 522 communicates with the upper vertical screw hole 525. The diameter of the lower vertical screw hole 521 is larger than the connection hole 522, and the diameter of the connection hole 522 is larger than the upper vertical screw hole 525. The horizontal hole 523 communicates with the connection hole 522.

The stop 520 is locked to the neck of the bottle 510. That is, the threaded neck of the bottle 510 is fitted into the lower vertical screw hole 521 of the stopper 520.

A screw 530 having a threaded outer surface is locked to the stop 520. That is, the screw 530 is fitted into the upper vertical screw hole 525 of the stopper 520. The screw 530 has a through hole 531 from the top to the bottom. When the imaginary extends vertically and horizontally, respectively, the perforations 531 in the screw 530 and the horizontal holes 523 in the stopper 520 do not coincide with each other.

One end of the tube 440 passes through the perforation 531 of the screw 530 and is positioned inside the bottle 510. This end of the tube 440 can remain in contact with the bottom of the bottle 510.

As shown in FIG. 3, the sensor 450 is provided on the bottle holder 430. The sensor 450 includes a transmitting portion 451 and a receiving portion 452. The sensor 450 senses whether the liquid crystal in the bottle 510 has risen to a reference level. The reference level is on the same line as the beam path that is emitted from the transmitting portion 451 and travels to the receiving portion 452.

The liquid crystal supply device includes a storage tank 620 provided on the bottom plate 610 for storing liquid crystal, a pressure supply unit 630 for supplying pressure to the storage tank 620, a connection pipe 640 connected between the storage tank 620 and the pressure supply unit 630, and a clean table. 10 a nozzle assembly 650 that is coupled to the inner surface of the wall of the clean bench 10, and a supply tube 660 that is coupled between the reservoir 620 and the nozzle assembly 650. The pressure supply unit 630 is mounted on the bottom plate 610.

The liquid crystal coater is usually surrounded by the clean bench 10 to prevent particles from contaminating the substrate mounted on the stage 200.

The nozzle assembly 650 includes a driving unit 652 coupled to the bottom plate 651, a sliding member 653 slidable by the driving unit 652, a holder 654 coupled to the sliding member 653, and a supporter 654 coupled to the holder 654. The tube supports tube 655, wherein one end of the tube support tube 655 extends from the holder 654.

The valve member 670 is mounted to the supply tube 660. The valve member opens or closes the supply tube 660 to supply liquid crystal or stop supplying liquid crystal.

The operation of the liquid crystal coater will now be described.

According to an instruction of the control unit (not shown), the coating head unit support frame 300 and the coating head unit 400 each having the bottle 510 filled with the liquid crystal are respectively moved in the Y-axis direction and the X-axis direction to pass through the nozzle unit 420. The liquid crystal drops are dropped onto the panel areas defined on the substrate. The liquid crystal in the bottle 510 is supplied to the nozzle unit 420 through the tube 440.

When the bottle 510 lacks the liquid crystal, the coating head unit support frame 300 and the coating head unit 400 move, and the bottle 510 installed in the coating head unit is positioned at the liquid crystal supply position. The liquid crystal supply position is such that the liquid crystal supply device can supply the liquid crystal to the position of the bottle 510 through the supply tube 660 combined with the tube support tube 655.

When the bottle 510 is positioned at the liquid crystal supply position, the drive unit 652 moves the tube support tube 655 forward and inserts the horizontal hole 523 locked in the stopper 520 of the bottle 510.

When the valve member 670 is opened, the liquid crystal permeation supply pipe 660 in the reservoir 620 is introduced into the horizontal hole 523 by the pressure applied to the reservoir 620.

As shown in FIG. 4, after the horizontal hole 523 is introduced, the liquid crystal flows down the inner surface of the bottle 510. As a result, the liquid crystal in the bottle 510 is raised.

The sensor 450 senses whether the liquid crystal in the bottle 510 has risen to a reference level. The position of the sensor 450 is determined in advance to allow the light beam emitted from the emitting portion 451 to travel to the receiving portion 452 along the reference level of the bottle 510. That is, the reference level is the same line as the path along which the light beam emitted from the transmitting portion 451 is. When the liquid crystal in the bottle 510 reaches the reference level, the amount of light received by the receiving portion 452 of the sensor 450 is smaller than the amount of light in the bottle 510 that has not reached the reference level. The sensor 450 transmits the light amount information received by the receiving portion 452 from the transmitting portion 451 to the control unit. The control unit determines whether the liquid crystal in the bottle 510 reaches the reference level based on the information of the sensor 450.

When the control unit (not shown) determines that the liquid crystal in the bottle 510 has risen to the reference level, the valve member 670 is instructed to close, and the liquid crystal is stopped from flowing into the bottle 510 from the reservoir 620 through the supply tube 660.

The drive unit 652 moves the tube support tube 655 backward, and withdraws the tube support tube 655 from the horizontal hole 523 of the stopper 520.

However, the liquid crystal flowing down the inner surface of the bottle 510 may pass through the light beam emitted from the emitting portion 451. At this time, the receiving portion 452 may receive a smaller amount of light than when the liquid crystal of the light beam emitted from the emitting portion 451 flows downward without flowing down the inner surface of the bottle 510. In this case, the sensor 450 transmits information of a smaller amount of light to the control unit. This can cause the control unit to incorrectly determine that the liquid crystal in the bottle 510 has risen to the reference level, but has not actually reached it.

Further, the liquid crystal flowing down the inner surface of the bottle 510 may leak from between the neck of the bottle 510 and the stopper 520.

Further, the liquid crystal may drip in a droplet manner after being introduced into the horizontal hole 523 instead of flowing down the inner surface of the bottle 510. The liquid crystal which rises in the bottle 510 thus causes bubble generation.

One of the objects of the present invention is to accurately determine the liquid crystal level in the bottle.

Another object of the invention is to avoid leakage of liquid crystal from between the neck of the bottle and the stop.

Another object of the present invention is to prevent liquid crystal from dripping down into the liquid crystal in the bottle in a droplet form.

According to one aspect of the invention, a liquid flow introducer is provided comprising a tubular member and a jaw projecting radially from one end of the tubular member.

The tubular member can include a retractable wrinkle.

According to another aspect of the present invention, there is provided a liquid flow guide comprising a tubular member, a jaw projecting radially from one end of the tubular member, and a slidable tube that slidably slides/slides into the tubular member.

The jaws may be formed from an elastic material.

One end of the tube 440 is positioned near the bottom of the bottle 710 or in contact with the bottom of the bottle 710 by a perforation 531 of the screw 530.

The stopper 720 may have a perforation at the top that communicates with the attachment hole 722. Tube 440 can be coupled to stop 720 with one end of tube 440 passing through the perforations in the top.

The first embodiment of the liquid flow introducer 730 includes a tubular member 731 and a jaw 732 that projects radially from the tubular member 731.

The tube 731 of the liquid flow guide has a uniform outer diameter and is straight. The tube 731 of the liquid flow introducer 730 is positioned inside the bottle 710. The jaw 732 is seated on top of the bottle 710. That is, the lower surface of the jaw 732 is in contact with the top of the bottle 710, and the upper surface of the jaw 732 is in contact with the contact surface 724 of the stopper 720.

The lower end of the tube 731 contacts the bottom of the bottle 710 or is positioned near the bottom of the bottle 710 but below the minimum level of liquid crystal in the bottle 710. This prevents the liquid crystal from dripping into the liquid crystal of the bottle 710 in the form of droplets. When the liquid crystal in the bottle 710 is at a minimum level or below a minimum level, the liquid crystal is supplied to the bottle 710.

The liquid crystal introduction passage P (including the connection hole 722 and the horizontal hole 723) in the stopper 720 communicates with the tube 731 of the liquid flow guide 730. Tube 440 is coupled to screw 530 with one end of tube 440 passing through screw 530. This end of the tube 440 passes through the connection hole 722 and the tube 731 of the liquid flow guide 730.

The perforation H can be located in the upper half of the tube 731. Through the perforation H, the inside of the tube 731 and the inside of the bottle 710 are in communication with each other. When the tube member 731 is immersed in the liquid crystal of the bottle 710, air is allowed to flow through the perforation H. Therefore, there is no difference between the liquid crystal level inside the tube 731 and the liquid crystal level outside the tube 731.

There may be two or more perforations H in the tube 731, which are arranged in one or more columns with respect to each other by a predetermined distance.

As shown in FIG. 9, a perforation H can be provided to the element 732.

The lower end of the tubular member 731 may have a slope 733 with respect to the bottom of the bottle 710. In this case, the liquid crystal flowing down the inner surface of the tube 731 flows down the slope 733 at the end of the tube 731 to the lower end of the tube 731, and is added to the liquid crystal in the bottle 710 instead of dropping down from the slope 733. The liquid crystal in the bottle 710.

The liquid flow introducer 730 can be formed from an elastomeric material. The liquid flow guide 730 may be formed of a fluorocarbon resin such as Teflon. The liquid flow guide 730 made of an elastic material prevents liquid crystal from leaking from between the neck of the bottle 710 and the stopper 720 because the jaw 732 of the liquid flow guide 730 is pressed against the top of the bottle 710 and the stopper 720. Between the contact faces 724.

As shown in FIG. 9, liquid flow introducer 730 has a longitudinal opening 734.

The slidable tube 738 is slid back and forth by the tube 731 such that the lower end of the tube 731 is maintained at a fixed distance from the bottom of the bottle 710. The slidable tube 738 can have an outer protrusion at the top, and the tube 731 can have an inner protrusion at the lower end. This prevents the slidable tube 738 from sliding completely out of the tube 731.

The perforations H may be provided to the tube 731 or the element 732.

The tube 731 of the liquid flow introducer 730 and the slidable tube 738 are positioned inside the bottle 710. The jaw 732 is seated on top of the bottle 710. That is, the lower surface of the jaw 732 is in contact with the top of the bottle 710, and the upper surface of the jaw 732 is in contact with the contact surface 724 of the stopper 720.

The lower end of the slidable tube 738 is in contact with the bottom of the bottle 710 or is positioned near the bottom of the bottle 710 but below the minimum level of liquid crystal in the bottle 710. This prevents the liquid crystal from dripping into the liquid crystal of the bottle 710 in the form of droplets.

The liquid crystal introduction passage P (including the connection hole 722 and the horizontal hole 723) in the stopper 720 communicates with the tube 731 of the liquid flow guide 730 and the slidable tube 738.

Tube 440 is coupled to screw 530 with one end of tube 440 passing through screw 530. This end of the tube 440 passes through the connecting hole 722 of the stopper 720 and the tube member 731 of the liquid flow guide 730 and the slidable tube 738.

The jaw 732 of the third embodiment of the liquid flow introducer 730 is identical to the jaw of the first embodiment of the liquid flow introducer 730.

The jaws 732 of the liquid flow guide 730 allow the liquid crystal guides 730 to be mounted to bottles 710 of different sizes. The slidable tube 738 slides back and forth such that the end of the slidable tube 738 maintains a fixed distance from the bottom of the bottle 710.

There may be two or more perforations H in the tube 731, which are arranged in one or more columns with respect to each other by a predetermined distance.

As with the first embodiment of the liquid flow introducer 730, the end of the slidable tube 738 can have a ramp 733 relative to the bottom of the bottle 710.

The liquid flow introducer 730 can be formed from an elastomeric material. The liquid flow guide 730 may be formed of a fluorocarbon resin such as Teflon.

The operation of the liquid crystal coater of any of the first embodiment, the second embodiment, and the third embodiment having the liquid flow guide 730 will now be described.

The coating head unit support frame 300 and the coating head unit 400 are moved, and the bottle 710 mounted on the coating head unit is positioned at the liquid crystal supply position. When the bottle 710 is positioned at the liquid crystal supply position, the drive unit 652 constituting the nozzle assembly 650 of the liquid crystal supply device moves the tube support tube 655 forward and is inserted into the horizontal hole 723 locked in the stopper 720 of the bottle 710.

When the valve member 670 of the liquid crystal supply device is opened, the liquid crystal transmission supply pipe 660 in the reservoir 620 is introduced into the horizontal hole 723 by the pressure applied to the reservoir 620.

As shown in FIG. 12, after introduction of the horizontal hole 723, the liquid crystal flows downward along the inner surface of the tube 731 of the liquid flow guide 730. As a result, the liquid crystal in the bottle 710 is raised.

The sensor 450 can sense whether the liquid crystal in the bottle 710 has risen to a reference level. The position of the sensor 450 is determined in advance to allow the light beam emitted from the transmitting portion 451 to pass through the reference level of the bottle 710 and then reach the receiving portion 452. That is, the reference level is the same line as the path along which the light beam emitted from the transmitting portion 451 is. When the liquid crystal in the bottle 710 reaches the reference level, the amount of light received by the receiving portion 452 of the sensor 450 is smaller than the amount of light when the liquid crystal in the bottle 710 has not reached the reference level. The sensor 450 transmits the light amount information received by the receiving portion 452 from the transmitting portion 451 to a control unit (not shown). The control unit determines whether the liquid crystal in the bottle 710 reaches the reference level based on the information of the sensor 450.

When the control unit determines that the liquid crystal in the bottle 710 has risen to the reference level, it indicates that the valve member 670 is closed, and stops flowing the liquid crystal from the reservoir 620 into the bottle 710 through the supply tube 660.

The drive unit 652 moves the tube support tube 655 backward, and withdraws the tube support tube 655 from the horizontal hole 723 of the stopper 720.

According to the instruction of the control unit, the coating head unit support frame 300 and the coating head unit 400 each having the bottle 710 filled with the liquid crystal are respectively moved in the Y-axis direction and the X-axis direction to drop the liquid crystal droplets through the nozzle unit 420. Onto each panel area defined on the substrate. The liquid crystal in the bottle 710 is supplied to the nozzle unit 420 through the tube 440.

The tube 731 inserted into the bottle 710 does not interfere with the light beam traveling from the emitting portion 451 to the receiving portion 452. Therefore, the liquid crystal flowing down the inner surface of the tube 731 does not interfere with the light beam traveling from the emitting portion 451 to the receiving portion 452. This enables the receiving portion 451 of the sensor 450 to receive the same amount of light as the emitting portion 451 of the sensor 450 until the liquid crystal in the bottle 710 reaches the reference level.

The liquid crystal of the horizontal hole 723 of the introduction stopper 720 flows downward along the inner surface of the tube 731 of the bottle 710 and is added to the liquid crystal in the bottle 710 instead of dropping the liquid crystal into the bottle 710 in the form of droplets. . The liquid crystal that does not rise in the bottle 710 thus generates bubbles.

The position of the jaw 732 between the top of the bottle 710 and the contact surface 724 of the stopper 720 prevents the liquid crystal introduced into the horizontal hole 723 from leaking between the bottle 710 and the stopper 720, and avoids the contact surface 724 from the stopper 720. The upper surface of the element 732 leaks.

In a second embodiment of the liquid flow introducer 730, the corrugations 736 telescope to maintain a fixed distance between the end of the lower portion 737 and the bottom of the bottle 710.

In a third embodiment of the liquid flow introducer 730, the slidable tube 738 slides back and forth such that the end of the slidable tube 738 maintains a fixed distance from the bottom of the bottle 710.

The present invention may be embodied in many forms without departing from the spirit and scope of the invention. It is to be understood that the above embodiments are not limited by the details of the foregoing description. The spirit and scope of the invention are to be interpreted broadly, and all such changes and modifications are intended to be included within the scope of the appended claims.
