Description

LCD cap

The present invention generally relates to a liquid crystal bottle cap, and more particularly to a liquid crystal bottle cap coupled to a liquid crystal bottle provided in a liquid crystallizer (LC dispenser), which has a supply hole. The liquid crystal is supplied to the liquid crystal bottle through the supply hole.

In general, a liquid crystal coating process for manufacturing a liquid crystal display method includes directly coating a liquid crystal to a glass panel, and bonding another glass panel to the glass panel to apply pressure to uniformly disperse the applied liquid crystal to the glass panel. The entire area, thus forming a liquid crystal layer. Liquid crystal coaters are commonly used to coat liquid crystals to glass panels.

1 is a schematic view showing an example of a liquid crystal coater having a liquid-crystal-supply unit. 2 is a side view showing a dispensing-head-unit and a liquid-crystal-injection unit of FIG. 1.

The liquid crystal coater includes one or more coating head units 20. Each of the coating head units 20 moves relative to the glass panel 70, and liquid crystal is applied from the nozzle 32 to the glass panel 70.

The coating head unit 20 includes a support assembly 22, a liquid crystal bottle 26, a bottle-support plate 24, a liquid crystal bottle cap 40 (hereinafter referred to as a bottle cap), a pump unit 30, and Pipe fittings (tube) 28. The support assembly 22 is movably coupled to a dispensing-head-unit-support frame 10. The liquid crystal bottle 26 stores liquid crystal to be applied to the glass panel 70. The liquid crystal bottle support plate 24 is coupled to the support assembly 22 and supports the liquid crystal bottle 26. The cap 40 is coupled to the neck 27 of the liquid crystal bottle 26 to close the opening of the liquid crystal bottle 26. The pump unit 30 extracts liquid crystal from the liquid crystal bottle 26 and supplies the liquid crystal to the nozzle 32. The first end of the tubular member 28 is inserted into the liquid crystal bottle 26 and the second end is connected to the pump unit 30. The liquid crystal stored in the liquid crystal bottle 26 is extracted by the pump unit 30 through the tube member 28, and then the liquid crystal is applied to the glass panel 70 through the nozzle 32.

When the liquid crystal coater is operated, the amount of liquid crystal in the liquid crystal bottle 26 of the coating head unit 20 is reduced. When the amount of liquid crystal in the liquid crystal bottle 26 falls to a predetermined level, the coating head unit 20 is moved to the liquid crystal supply position, and the liquid crystal is supplied from the liquid-crystal-supply unit 50 to the liquid crystal bottle 26.

The liquid crystal supply unit 50 is usually disposed outside the cover frame 90. The liquid crystal supply unit 50 includes a liquid crystal carrier 52 in which liquid crystal is stored, and a liquid crystal injection unit 54 that injects liquid crystal from the liquid crystal cell 52 into the liquid crystal bottle 26.

A supply passage 42 is formed in the bottle cap 40, and the liquid crystal is supplied from the liquid crystal supply unit 50 to the liquid crystal bottle 26 through the supply passage 42. The supply passage 42 includes a common hole 44 extending vertically from the bottom of the bottle cap 40 and a supply hole 46 extending from the circumferential outer surface of the bottle cap 40 to the circumferential inner surface of the common hole 44.

Figure 3 is a side cross-sectional view showing the supply of liquid crystal to the liquid crystal bottle by inserting a supply pipe into the supply passage of the cap of Figure 2.

In order to supply the liquid crystal to the liquid crystal bottle 26, the supply tube 56 is linearly moved toward the cap 40 by an actuator 58, and the cap 40 is inserted through the supply hole 46. Thereafter, the liquid crystal is supplied from the liquid crystal cell 52 to the bottle cap 40 through the supply tube 56. The liquid crystal supplied through the supply pipe 56 enters the liquid crystal bottle 26 through the supply passage 42 formed in the bottle cap 40. When the amount of liquid crystal supplied to the liquid crystal bottle 26 reaches a predetermined level, the supply of the liquid crystal is stopped, and the supply tube 56 is removed from the bottle cap 40 by the actuator 58.

The liquid crystal supplied from the supply pipe 56 is horizontally ejected from the supply pipe. The cap 40 defines the inner wall of the supply passage 42 (i.e., the inner wall of the common bore 44) to be vertically positioned. Therefore, the liquid crystal emitted from the supply pipe 56 hits the inner surface of the cap 40 in a direction almost perpendicular to the inner wall of the cap 40. Some of the liquid crystal that hits the inner surface of the cap 40 is applied to the supply tube 56 or splashed through the supply opening 46 of the cap 40 from the cap 40. The liquid crystal splashed from the cap 40 after hitting the inner wall of the cap 40 also contaminates other components of the liquid crystal coater. Further, if the liquid crystal splashed from the bottle cap 40 drops onto the glass panel 70, a liquid crystal display may be defective.

Further, in order to supply the liquid crystal to the liquid crystal bottle 26 by the liquid crystal supply unit 50, when the supply tube 56 is inserted into the cap 40, the supply hole 46 of the cap 40 must face the supply tube 56. In other words, the supply aperture 46 of the cap 40 must be on the same extension line as the supply tube 56. When the liquid has the cap 40 When the crystal bottle 26 is mounted on the liquid crystal bottle support plate 24, the operator adjusts the orientation of the bottle cap 40 such that the supply hole 46 of the bottle cap 40 faces the supply tube 56. However, since the operator only uses the feeling to perform the work of adjusting the supply hole 46 of the cap 40, the supply hole 46 of the cap 40 is difficult to accurately face the supply tube 56, and it takes a considerable time to adjust the cap 40. Orientation.

Further, when the liquid crystal bottle 26 is mounted on the liquid crystal bottle support plate 24, even if the orientation of the supply hole 46 of the cap 40 can be accurately adjusted to face the supply tube 56, the liquid crystal bottle 26 on the liquid crystal bottle support plate 24 may be When the liquid crystal coater operates, the vibration generated by the head unit 20 is applied to rotate around the axis. Thereby, it is possible to change the orientation of the supply hole 46 of the cap 40 coupled to the liquid crystal bottle 26. As a result, if the supply hole 46 is not facing the supply pipe 56 of the liquid crystal supply unit 50 due to the orientation variation of the supply hole 46, the supply pipe 56 is not correctly inserted into the cap 40, for example, a bottle may be encountered. The outer wall of the cover 40 cannot supply liquid crystal into the liquid crystal bottle 26.

Accordingly, the present invention has been made in view of the problems occurring in the prior art, and an object of the present invention is to provide a bottle cap which can prevent liquid crystal from hitting the inner wall of the cap from being applied to or splashed from the cap when injecting the liquid crystal.

Figure 6 is a vertical sectional view of Figure 5. Figure 7 is a vertical cross-sectional view showing the use of a cap coupled to a liquid crystal bottle and a guiding member in accordance with a first embodiment of the present invention.

The bottle cap 100 according to the first embodiment of the present invention is coupled to the neck portion 510 of the liquid crystal bottle 500, wherein the liquid crystal bottle 500 is provided to the coating head unit 800 of the liquid crystal coater. The liquid crystal bottle 500 to which the cap of the present invention is coupled may include, for example, a bottle containing a storage space for storing liquid crystal, and has a neck portion 510 at its upper end communicating with the receiving space, and external threads forming a circumference around the neck. The outer surface of the circumference of 510. The liquid crystal bottle 500 is supported by a liquid crystal bottle support plate 830 provided on the coating head unit 800. The liquid crystal bottle support plate 830 includes a bottom-support part 832 that supports the bottom of the liquid crystal bottle 500, and a side support portion that is provided around the upper surface of the bottom support portion 832 and supports the circumferential outer surface of the liquid crystal bottle 500 (side- Support part)834.

The bottle cap 100 according to the first embodiment of the present invention includes an orientation setting frame 110 coupling the liquid crystal bottle 500 and the guiding member 840, a funnel 120 inserted into the orientation setting frame 110, a liquid crystal guiding member 130 inserted into the funnel 120, and a coupling funnel. A guide pipe 140 of 120.

The orientation setting frame 110 includes a coupling hole 113 that sleeves the neck portion 510 of the liquid crystal bottle 500, a funnel insertion hole 111 that communicates with the coupling hole 113, a first supply hole 112 that communicates with the funnel insertion hole 111, and a predetermined planar shape. The reference portion 117 is inserted. The orientation setting frame 110 for the accommodating funnel 120 and the liquid crystal guiding member 130 is coupled to the liquid crystal bottle 500 and the guiding member 840, and the liquid crystal bottle 500 is fixed to the liquid crystal bottle supporting plate 830, and the funnel 120 is set. Both the supply aperture 124 and the inclined surface 132 of the liquid crystal guide 130 are oriented relative to the orientation of the coating head unit 800.

The coupling hole 113 includes a first hole 113a and a second hole 113b. The first hole 113a is formed in the lower surface of the orientation setting frame 110. The second hole 113b communicates with the first hole 113a and has a smaller diameter than the first hole 113a. The internal thread is formed on the circumferential inner surface of the second hole 113b. The coupling hole 113 is screwed to the liquid crystal bottle 500 by engaging the internal thread of the second hole 113b with the external thread formed on the outer circumferential surface of the neck portion 510 of the liquid crystal bottle 500. The first hole 113a is formed to allow the orientation setting bracket 110 to completely accommodate the neck portion 510 of the liquid crystal bottle 500. In this embodiment, the protruding portion 512 protrudes from the neck portion 510 of the liquid crystal bottle 500 in the radial direction of the liquid crystal cell 500. Unlike this embodiment, in the case where the neck 510 does not have a projection, or the orientation setting bracket 110 is configured to be coupled only by threading and the neck 510 is not fully received in the orientation setting bracket 110 In the case of receiving the neck 510 of the liquid crystal bottle 500, the first hole 113a may be omitted.

The funnel insertion hole 111 extends from the upper surface of the orientation setting frame 110 to a predetermined depth. The funnel insertion hole 111 communicates with the coupling hole 113. The funnel 120 is inserted into the funnel insertion hole 111.

The first supply hole 112 is formed in the side wall of the orientation setting frame 110 and extends from the circumferential outer surface of the orientation setting frame 110 to the circumferential inner surface of the funnel insertion hole 111, so that the first supply hole 112 communicates with the funnel insertion hole 111. When the orientation setting bracket 110 is coupled to the guiding member 840, the first supply hole 112 just faces the supply tube 710 of the liquid crystal supply unit 700. When the liquid crystal is supplied from the liquid crystal supply unit 700 to the liquid crystal bottle 500, the liquid crystal is supplied to the liquid crystal bottle through the first supply hole 112 of the orientation setting frame 110. 500. Herein, after a part of the supply tube 710 has been inserted into the orientation setting frame 110 through the first supply hole 112, the liquid crystal is injected into the liquid crystal bottle 500. To this end, the inner diameter of the first supply hole 112 is preferably at least substantially larger than the outer diameter of the supply tube 710.

The insertion reference portion 117 protrudes upward from the upper surface of the orientation setting frame 110. Each of the funnel 120 and the liquid crystal guide 130 has a first azimuth setting unit 126 and a second azimuth setting unit 134, and the shape thereof corresponds to the shape of the insertion reference portion 117. The insertion reference portion 117 acts to guide the insertion orientation of the funnel 120 and the liquid crystal guide 130 such that when the funnel 120 and the liquid crystal guide 130 are inserted into the orientation setting frame 110, the second supply hole 124 of the funnel 120 and the liquid crystal guide The inclined surface 132 of the 130 faces the first supply hole 112. In this way, since the insertion orientation of the funnel 120 and the liquid crystal guide 130 is guided by the insertion reference portion 117, when the funnel 120 and the liquid crystal guide 130 are inserted into the orientation setting frame 110, the second supply hole 124 is avoided. The inclined surface 132 performs unnecessary rotation in a random direction around the central axis of the funnel insertion hole 111. The funnel 120 and the liquid crystal guide 130 can be inserted into the orientation setting frame 110 only when the first orientation setting portion 126 and the second orientation setting portion 134 face the insertion reference portion 117. Therefore, when the funnel 120 and the liquid crystal guide 130 are inserted into the orientation setting frame 110, the orientations of the first supply hole 112 and the inclined surface 132 with respect to the orientation setting frame 110 are always in a certain direction. In this embodiment, the front surface of the insertion reference portion 117 has a linear planar shape. Furthermore, the surfaces of the first azimuth setting portion 126 and the second azimuth setting portion 134 facing the front surface of the insertion reference portion 117 have a linear planar shape. In this way, in the present invention, the first orientation setting unit 126 and the second orientation setting unit 134 The surface facing the insertion reference portion 117 has a linear planar shape, and the second supply hole 124 and the inclined surface 132 are oriented to face the surface of the first orientation setting portion 126 and the second orientation setting portion 134 facing the insertion reference portion 117. The direction. Therefore, when the funnel 120 and the liquid crystal guide 130 are inserted into the orientation setting frame 110, the second supply hole 124 and the inclined surface 132 may be oriented toward the first supply hole 112. Further, when the gap between the insertion reference portion 117 and the first orientation setting portion 126 and the second orientation setting portion 134 is reduced, the gap for allowing the funnel 120 and the liquid crystal guide 130 to rotate is reduced, and the second supply can be further enhanced. The orientation of the aperture 124 and the inclined surface 132 relative to the first supply aperture 112 is uniform.

Further, in the flange 128 and the seating part 136 (described later in detail), portions other than the first orientation setting portion 126 and the second orientation setting portion 134 have non-corresponding insertion reference portions 117. shape. Thereby, the funnel 120 and the liquid crystal guide 130 can be prevented from being improperly inserted into the orientation setting frame 110. For example, the length from the circumferential surface of the funnel 120 to the end of the orientation setting portion 126 is approximately equal to the length from the circumferential inner surface of the funnel insertion hole 111 to the surface before the insertion of the reference portion 117. Further, a portion of the flange 128 other than the first orientation setting portion 126 extends radially from the circumferential outer surface of the funnel 120 by a length greater than a length between the circumferential inner surface of the funnel insertion hole 111 and the front surface of the insertion reference portion 117. . Then, the funnel 120 can be inserted into the orientation setting frame 110 only when the first orientation setting portion 126 faces the insertion reference portion 117. In the present embodiment, although the insertion reference portion 117, the first orientation setting portion 126, and the second orientation setting portion 134 are displayed to have a linear planar shape, they may be changed and may have various shapes such as a V shape, a zigzag shape, a curved shape, or the like. .

The orientation setting bracket 110 is fixed to the coating head unit 800 by being coupled to the guiding member 840. The shape and mounting position of the guiding member 840 and the structure coupling the orientation setting bracket 110 to the guiding member 840 can be implemented in various manners. In the present embodiment, the guiding member 840 has a bar shape coupled to a predetermined portion of the side support portion 834 of the liquid crystal bottle support plate 830. However, the shape and mounting of the guiding member 840 of the present invention are not limited to the embodiments. For example, the guiding member 840 can be coupled to other elements of the coating head unit 800 or can include a portion of other elements of the coating head unit 800. In order to couple the cap 100 to the guiding member 840, a guide-member-insert depression 118 into which the guiding member 840 is inserted is formed in the orientation setting frame 110. In detail, the guide member insertion groove 118 is formed on the rear surface of the orientation setting frame 110, and extends from the upper surface to the lower surface of the orientation setting frame 110 and is open toward the rear. The orientation setting bracket 110 may be coupled to the guiding member 840 in such a manner that the orientation setting bracket 110 is disposed in front of the guiding member 840 and pushed in the horizontal direction toward the guiding member 840, while the guiding member 840 is horizontally inserted into the guiding member insertion The groove 118; or alternatively, the orientation setting frame 110 may be disposed directly above the guiding member 840 and pushed in the vertical direction toward the guiding member 840, and the guiding member 840 is vertically inserted into the guiding member insertion groove 118 . As such, the orientation setting bracket 110 can be secured to the coating head unit 800 by coupling the orientation setting bracket 110 to the guiding member 840 that is fixed to the coating head unit 800. In the present embodiment, a ball plunger 400 is used as a means for fixing the orientation setting bracket 110 to the guiding member 840. The ball plunger 400 is provided in the opposite inner wall of the guide member insertion groove 118 and is disposed in the vertical direction In the direction. Thereby, the orientation setting frame 110 and the guiding member 840 can be easily coupled or removed. At the same time, a bolt (not shown) can be used to couple the orientation setting bracket 110 to the guiding member 840.

When the orientation setting bracket 110 is coupled to the guiding member 840, the orientation and position of the orientation setting bracket 110 relative to the coating head unit 800 is determined. In addition, the position and orientation of the funnel 120 and the liquid crystal guide 130 are determined by the orientation setting frame 110. Therefore, the position and orientation of the funnel 120 and the liquid crystal guide 130 relative to the coating head unit 800 are determined by the coupling of the orientation setting frame 110 and the guiding member 840. Moreover, because the orientation setting frame 110 is coupled to the guiding member 840 after being coupled to the liquid crystal bottle 500. Therefore, the liquid crystal bottle 500 can also be fixed to the liquid crystal bottle support plate 830. In consideration of the vibration of the liquid crystal bottle 500 when the liquid crystal coater operates, in the present invention, since the liquid crystal bottle 500 is fixed to the liquid crystal bottle support plate 830 by the orientation setting frame 110, the liquid crystal bottle 500 is prevented from vibrating. Therefore, when the liquid crystal coater is operated, the liquid crystal in the liquid crystal bottle 500 can be prevented from being splashed from the liquid crystal bottle 500, or the liquid crystal in the liquid crystal bottle 500 can be prevented from generating bubbles. Moreover, when the liquid crystal coater operates to prevent the funnel 120 or the liquid crystal guide 130 from rotating about the axis, the first supply hole 112 of the orientation setting frame 110, the second supply hole 124 of the funnel 120, and the liquid crystal guide can be The orientation of the inclined face 132 of 130 is always fixed.

The funnel 120 has a flow hole 122, a second supply hole 124, a flange 128, and a first orientation setting portion 126. The circulation hole 122 is formed from the upper surface of the funnel 120 to the lower surface. The second supply hole 124 communicates the first supply hole 112 with the flow hole 122. The flange 128 determines the orientation of the funnel 120 insertion The depth of the shelf 110. The first orientation setting portion 126 has a shape corresponding to the planar shape of the insertion reference portion 117. The funnel 120 having the above structure is inserted into the funnel insertion hole 111.

The circulation hole 122 functions as a flow passage through which the liquid crystal to be supplied from the supply pipe 710 flows. The liquid crystal supplied to the flow holes 122 through the second supply holes 124 flows out through the outlets 125. Preferably, the diameter of the flow hole 122 (i.e., the inner diameter of the funnel 120) is gradually reduced from top to bottom. The diameter of the flow hole 122 can be reduced stepwise or continuously.

The second supply hole 124 of the funnel 120 is formed from the circumferential outer surface of the funnel 120 to the outer side surface of the flow hole 122, and the first supply hole 112 of the orientation setting frame 110 is communicated with the flow hole 122 through the second supply hole 124. When the funnel 120 is disposed in the orientation setting frame 110, the second supply aperture 124 of the funnel 120 is in fluid communication with the first supply aperture 112 of the orientation setting bracket 110. The liquid crystal supplied through the second supply hole 124 of the funnel 120 enters the liquid crystal bottle 500 through the outlet 125 through the flow hole 122. Preferably, the outlet 125 of the funnel 120 is disposed in the liquid crystal bottle 500 to prevent liquid crystal from leaking from the junction between the neck 510 of the liquid crystal bottle 500 and the coupling hole 113 during the process of supplying the liquid crystal to the liquid crystal bottle 500.

A flange 128 is provided at the upper end of the funnel 120 and extends radially in the funnel 120. When the funnel 120 is inserted into the orientation setting frame 110, the lower surface of the flange 128 is placed on the upper surface of the orientation setting frame 110, thereby determining the insertion depth of the funnel 120.

When the funnel 120 is inserted into the orientation setting frame 110, the first orientation setting portion 126 is formed at a position where the flange 128 faces the insertion reference portion 117. As described above, the first orientation setting portion 126 has a shape corresponding to the insertion reference portion 117.

The liquid crystal guide 130 includes an inclined surface 132, a seating portion 136, a second orientation setting portion 134, and a tube-insert hole 138. The inclined surface 132 is inclined downward with respect to the direction in which the liquid crystal is supplied to the flow hole 122. The seating portion 136 determines the insertion depth of the liquid crystal guide 130. The second orientation setting portion 134 has a shape corresponding to the plane surface of the insertion reference portion 117. The tube 850 is inserted through the tube insertion hole 138. The liquid crystal guide 130 having this structure is inserted into the flow hole 122.

In detail, the inclined surface 132 is disposed in the flow hole 122 of the funnel 120 and is inclined downward with respect to the direction in which the liquid crystal is supplied to the flow hole 122. Regarding the supply of the liquid crystal through the bottle cap 100 to the liquid crystal bottle 500, according to the speed at which the liquid crystal supply unit 700 supplies the liquid crystal to the liquid crystal bottle 500, the liquid crystal may be guided to the outlet 125 of the funnel 120 after hitting the inclined surface 132 of the liquid crystal guide 130. Alternatively, the liquid crystal may be directed to the exit 125 of the funnel 120 without touching the inclined surface 132 of the liquid crystal guide 130. In the present invention, since the inclined surface 132 is inclined downward with respect to the direction in which the liquid crystal is supplied to the flow hole 122, the liquid crystal that hits the inclined surface 132 is bounced toward the outlet 125 of the funnel 120. This prevents the liquid crystal from splashing out of the cap 100. In other words, since the inclined surface 132 that the liquid crystal injected into the flow hole 122 hits is inclined downward with respect to the injection direction of the liquid crystal, instead of being oriented perpendicular to the injection direction of the liquid crystal, the inclined surface is inclined. The rebounded liquid crystal will be directed to the exit 125 of the funnel 120 instead of being directed to the second supply aperture 124 of the funnel 120.

The seating portion 136 is provided at the upper end of the liquid crystal guide 130 and has a diameter larger than the flow hole 122. When the liquid crystal guide 130 is inserted into the funnel 120, the lower surface of the seating portion 136 is disposed on the upper surface of the flange 128 of the funnel 120, thereby determining the insertion depth of the liquid crystal guide 130.

The second orientation setting portion 134 is formed in the liquid crystal guide 130, and is in a position facing the insertion reference portion 117 when the liquid crystal guide 130 is inserted into the funnel 120. As described above, the second orientation setting portion 134 has a shape corresponding to the insertion reference portion 117.

The tube insertion hole 138 is formed from the upper surface of the liquid crystal guide 130 to the lower surface. The tube insertion hole 138 communicates with the flow hole 122 and the coupling hole 113. The tube member 850 is inserted into the tube insertion hole 138. The first end of the tube 850 is disposed near the bottom of the liquid crystal bottle 500, and the second end is coupled to the pump unit 810. In order to prevent the liquid crystal from hitting the tube member 850, when the liquid crystal is supplied to the liquid crystal bottle 500, the line extending linearly from the tube insertion hole 138 preferably does not intersect the line extending linearly from the first supply hole 112 of the orientation setting frame 110. To this end, when the first supply hole 112 is disposed on the center line of the azimuth setting frame 110 with respect to the horizontal plane, the pipe insertion hole 138 is disposed at a position displaced to the left or right from the center line of the azimuth setting frame 110.

The guide tube 140 has a hollow column shape and has a flow passage extending from an upper end to a lower end thereof. The guide tube 140 is coupled to the funnel 120. Guide tube 140 The flow passage communicates with the flow hole 122. An extension 142 extending in the radial direction of the guide tube 140 is provided at the upper end of the guide tube 140. The extension portion 142 is disposed on the upper surface of the neck portion 510 of the liquid crystal bottle 500. The guiding tube 140 acts to prevent the liquid crystal supplied to the liquid crystal bottle 500 from flowing along the inner wall of the liquid crystal bottle 500 or rebounding from the liquid crystal already in the liquid crystal bottle 500. The guide tube 140 is coupled to the funnel 120 such that the flow channel communicates with the outlet 125. Therefore, the liquid crystal injected into the flow hole 122 is supplied to the liquid crystal bottle 500 through the guide tube 140. Preferably, the inner diameter of the guide tube 140 is equal to or slightly smaller than the outer diameter of the lower end of the funnel 120, and the lower end of the funnel 120 can be forced into the guide tube 140.

The liquid crystal supply unit 700 generally includes a liquid-crystal detecting sensor (not shown), which detects whether the liquid crystal in the liquid crystal bottle 500 appears at a predetermined height at which the liquid crystal detecting sensor is mounted, and thus detects It is determined whether the liquid crystal height in the liquid crystal bottle 500 is smaller than the height at which the liquid crystal detecting sensor can detect the liquid crystal or is equal to or higher than the height. When the liquid crystal is supplied from the liquid crystal supply unit 700 to the liquid crystal bottle 500, once the liquid crystal in the liquid crystal bottle 500 reaches a predetermined height detected by the liquid crystal detecting sensor, the supply of the liquid crystal to the liquid crystal bottle 500 is stopped. In general, the liquid crystal detecting sensor detects whether or not the liquid crystal appears at a specific height according to a change in light intensity passing through the liquid crystal bottle 500 when light is supplied to the liquid crystal bottle 500. Herein, if the liquid crystal supplied to the liquid crystal bottle 500 flows along the inner wall of the liquid crystal bottle 500, the light emitted from the liquid crystal detecting sensor can pass through the liquid crystal flowing along the inner wall of the liquid crystal bottle 500. In this case, the light intensity passing through the liquid crystal bottle 500 is lowered. Therefore, even if the liquid crystal in the liquid crystal bottle 500 does not reach the desired height, the liquid crystal detecting sensor may not detect correctly. The liquid crystal in the liquid crystal bottle 500 has reached the desired height. In the present invention, the liquid crystal is supplied to the liquid crystal bottle 500 along the guiding tube 140, and the liquid crystal detecting sensor can be prevented from being erroneous.

Meanwhile, in order to reduce the number of times the liquid crystal is supplied to the liquid crystal bottle 500, a large amount of liquid crystal must be supplied to the liquid crystal bottle 500 as much as possible. If liquid crystal is injected into the liquid crystal bottle when the liquid crystal bottle 500 has a liquid crystal height in the vicinity of the second supply hole 124, the liquid crystal injected into the liquid crystal bottle 500 may hit the liquid crystal surface of the liquid crystal bottle 500, and thus may come from the liquid crystal bottle. 500 splatters. However, in the present invention, since the liquid crystal is supplied to the liquid crystal bottle 500 along the guiding tube 140, it is possible to prevent the liquid crystal from rebounding from the liquid crystal surface already in the liquid crystal bottle 500.

Although the guide tube 140 provides several advantages, it is not an essential element for achieving the purpose of the cap of the present invention. In other words, the guide tube 140 can be used arbitrarily as needed.

In order to keep the funnel 120 and the liquid crystal guide 130 coupled to the orientation setting frame 110, bolt holes 119, 129, and 139 are formed at predetermined positions of the orientation setting frame 110, the funnel 120, and the liquid crystal guiding member 130, respectively. Can communicate with each other. After the funnel 120 and the liquid crystal guide 130 have been inserted into the orientation setting frame 110, bolts (not shown) are locked to the bolt holes 119, 129 and 139, so that the funnel 120, the liquid crystal guide 130 and the orientation setting frame 110 can be held at The state of the integrated coupling.

In the bottle cap 100 according to the first embodiment of the present invention, because of the orientation The setting frame 110 is fixed to the coating head unit 800, so that the orientation of the first supply hole 112 of the orientation setting frame 110 and the second supply hole 124 of the funnel 120 can be kept fixed with respect to the coating head unit 800. When the operator combines the bottle cap 100, the funnel 120 and the liquid crystal guide 130 are coupled to the orientation setting frame 110 only when the first orientation setting portion 126 and the second orientation setting portion 134 face the insertion reference portion 117, instead of It is necessary to pay special attention to the orientation of the second supply hole 124 of the funnel 120 and the inclined surface 132 of the liquid crystal guide 130, so that the first supply hole 112 of the orientation setting frame 110, the second supply hole 124 of the funnel 120, and the liquid crystal can be easily removed. The inclined faces 132 of the guides 130 are positioned in the same correct direction. Furthermore, after the cap 100 has been coupled to the guiding member 840, the first supply hole 112, the second supply hole 124, and the inclined surface 132 are reliably held in a state of facing the supply tube 710. Therefore, the supply tube 710 can be properly inserted into the orientation setting frame 110 without colliding with the outer surface of the orientation setting frame 110. The liquid crystal which is discharged from the supply tube 710 and hits the inclined surface 132 of the liquid crystal guide 130 is always redirected to the fixed correct direction by the inclined surface 132. Further, the orientations of the first supply hole 112, the second supply hole 124, and the inclined surface 132 are prevented from being displaced from the supply tube 710 due to vibration generated when the liquid crystal coater operates.

Hereinafter, a method of combining the caps according to the first embodiment of the present invention and a procedure of injecting liquid crystal from the liquid crystal supply unit 700 to the liquid crystal bottle 500 will be described with reference to the above elements.

The funnel 120 is inserted into the funnel insertion hole 111 of the orientation setting frame 110. Thereafter, the liquid crystal guide 130 is inserted into the flow hole 122 of the funnel 120. When the funnel 120 and the liquid crystal guide 130 are inserted, the funnel 120 and the liquid crystal are The guide 130 is oriented such that the first orientation setting portion 126 and the second orientation setting portion 134 face the insertion reference portion 117. When the insertion of the funnel 120 and the liquid crystal guide 130 has been completed, the first supply hole 112, the second supply hole 124, and the inclined surface 132 are oriented in the same direction. In this state, the funnel 120 and the liquid crystal guide 130 are coupled to the orientation setting frame 110 by bolts (not shown). Next, the lower end of the funnel 120 is inserted into the guide tube 140, thus completing the assembly of the cap 100. In the case where the structure of the cap 100 is not changed, the above assembly sequence can be changed.

In order to use the cap 100, the cap 100 is first coupled to the liquid crystal bottle 500. In detail, the neck 510 of the liquid crystal bottle 500 is inserted into the coupling hole 113 of the orientation setting bracket 110, and the bottle cap 100 and the liquid crystal bottle 500 are coupled to each other with respect to each other. Thereafter, the cap 100 coupled to the liquid crystal bottle 500 is coupled to the guiding member 840. When the guiding member 840 is inserted into the guiding member insertion groove 118 of the orientation setting frame 110, the liquid crystal bottle 500 is placed on the liquid crystal bottle supporting plate 830. Next, the second end of the tube member 850 to which the first end is connected to the pump unit 810 is inserted into the tube insertion hole 138, thus completing the preparation for supplying the liquid crystal from the liquid crystal bottle 500 to the pump unit 810.

In order to supply the liquid crystal from the liquid crystal supply unit 700 to the liquid crystal bottle 500, the coating head unit 800 is first moved to the liquid crystal supply position. Thereafter, the supply tube 710 of the liquid crystal supply unit 700 is moved toward the cap 100 and then inserted into the first supply hole 112. After the supply pipe 710 includes a portion of the end portion inserted into the flow hole 122, the liquid crystal is supplied from the supply pipe 710 to the flow hole 122. The liquid crystal supplied from the flow hole 122 passes through the outlet 125 of the funnel 120 and the guide tube 140 flows into the liquid crystal bottle 500. After the liquid crystal is supplied to the liquid crystal bottle 500, The pipe 710 is removed from the orientation setting frame 110.

Meanwhile, in the first embodiment, the orientation setting frame 110, the funnel 120, and the liquid crystal guide 130 constituting the bottle cap 100 are formed separately. The reason why the cap 100 contains separately formed elements is that it will contribute to the manufacturing process of the cap 100. If desired, the orientation setting frame 110 and the funnel 120 may be integrally formed, and the orientation setting frame 110, the funnel 120, and the liquid crystal guiding member 130 may form a single body.

The orientation setting frame 310 performs the same function as the orientation setting frame of the first embodiment. That is, since the inclined surface 332 is disposed in the flow hole 322, the liquid crystal supplied to the flow hole 322 can be prevented from being splashed from the bottle cap 300. Furthermore, after the first orientation setting frame 310 has been coupled to the liquid crystal bottle 500, and after the first orientation setting frame 310, the funnel 320, and the liquid crystal guiding member 330 have been fixed to the second orientation setting frame 340, the second orientation setting is performed.
