At this time, the chemical solution coating units 140 and 140A may be formed in various forms. For example, in one embodiment, the chemical coating portion 140 or 140A is rotatably installed in the moving block 120, and the chemical coating portion 140 or 140A may be disposed to be in contact with or immersed in the chemical solution C stored in the chemical solution storage portion 130 A supply roller 141 may be provided.

The chemical solution coating unit 140 or 140A is not limited to the above and may be formed in various forms. Hereinafter, for the sake of convenience, the following description will focus on the case where the chemical coating unit 140 or 140A includes the first roller 141A and the second roller 142A . The first roller 141A and the second roller 142A may be connected to the moving block 120 through a separate bracket 113. [ At this time, the surface of at least one of the first roller 141A and the second roller 142A may be formed in various forms to store the chemical solution C.

Therefore, the chemical liquid (C) can be smoothly supplied by storing the chemical liquid (C) in the space as described above. At this time, the surface of at least one of the first roller 141A_ and the second roller 142A is not limited to the above-described shape, but may include all shapes and all structures capable of storing a certain amount of the medicinal liquid C . Hereinafter, for convenience of explanation, a case where a mesh-shaped groove is formed on the surface of the first roller 141A will be described in detail.

In addition, at least one of the first roller 141A and the second roller 142A may be formed of a metal material at the center portion and an elastic material such as plastic, rubber, silicone, or the like. In another embodiment, at least one of the first roller 141A and the second roller 142A is formed of a first metal material at the center portion and a second metal material that is more flexible than the first metal material . In yet another embodiment, the first roller 141A and the second roller 142A may be formed entirely of a metal material. Hereinafter, for convenience of explanation, the first roller 141A and the second roller 142A will be described in detail with respect to the case where the central portion is formed of a metal material and the outer portion thereof is formed of an elastic material.

Meanwhile, the glass supporting part 160 may be installed to be linearly movable with respect to the supporting part 110. In particular, the glass support 160 can be installed on the second support frame 112 so as to be able to move up and down. The glass support 160 includes a glass support frame 161 installed to be linearly movable with respect to the second support frame 112, a fixing part 162 installed on the glass support frame 161 to attract the glass G, And a rotation driving unit 163 connected to the fixing unit 162 to rotate the fixing unit 162. A linear drive unit 180 such as a motor, a cylinder, or the like is installed between the glass support frame 161 and the second support frame 112 to linearly move the glass support frame 161. In addition, the fixing portion 162 may include a device capable of fixing the glass such as a point-deflector, a vacuum chuck, or the like. In addition, the rotation driving unit 163 may include a motor.

The rotation driving unit 163 may be formed in various shapes. For example, the rotation driving portion 163 may be in the form of a motor that is directly connected to the fixing portion 162. The rotary drive unit 163 includes a first pulley 163A connected to the fixed portion 162, a belt 163C connected to the first pulley 163A, a second pulley 163C connected to the belt 163C, 163B, and a motor 163D coupled directly to the second pulley 163B. As another embodiment, the rotation drive unit 163 may include a motor, and a gear unit connected to the motor. At this time, the gear unit may be connected to the fixed portion 162 to transmit the rotational force of the motor to the fixed portion 162. [ The rotation driving unit 163 is not limited to the above and may include all the devices and all structures that are connected to the fixing unit 162 to rotate the fixing unit 162. Hereinafter, for convenience of explanation, the rotation drive unit 163 will be described in detail with reference to a case including a first pulley 163A, a belt 163C, a second pulley 163B, and a motor 163D .

The balancing unit 170 is connected to the moving block 120 to prevent excessive movement of the moving block 120 when the moving block 120 moves. Specifically, when the glass coating unit 140 or 140A is pressed while the glass G rotates, the movable block 120 can be moved by the force. At this time, the balancing unit 170 may restrict the movement of the mobile block 120 so that the movement of the mobile block 120 does not excessively deviate from the first support frame 111. [

The balancing portion 170 includes a cable 171 connected to the mobile block 120, a guide portion 172 for guiding and guiding the cable 171 in the downward direction of the support portion 110, And a weight weight 173. At this time, the guide portion 172 is formed in a roller shape so that the cable 171 can be bent. The weight 173 may be weighted considering the weight of the moving block 120, the magnitude of the force applied by the glass G, and the like.

The curing portion 191 can heat the rim of the polished glass (G). The curing portion 191 can harden the chemical liquid C by heating the rim of the glass G coated with the chemical liquid C. [ At this time, the curing unit 191 can irradiate infrared rays, laser, or the like to the glass G. [

The curing portion 191 may be fixed to the glass support 161. At this time, the curing portion 191 is disposed so as to protrude from the glass support portion 161, and the position thereof can be varied. The curing portion 191 may be fixed to the glass support portion 161 through a separate bracket. In particular, the curing portion 191 can be installed at various positions of the bracket. The curing portion 191 is connected to a separate guide 193 and the sliding portion 192 so that the glass support portion 161 can linearly move along with the linear movement. At this time, the sliding portion 192 may be connected to the curing portion 191 and may linearly move along the guide 193 when the crying portion 191 is linearly nested.

The rotation measuring unit 195 may be installed to be connected to the chemical coating unit 140. At this time, the rotation measuring unit 195 is connected to at least one of the first roller 141A and the second roller 142A to detect the rotation speed of at least one of the first roller 141A and the second roller 142A . For example, the rotation measuring section 195 may be in the form of an encoder connected to measure the rotational speed of at least one of the first roller 141A and the second roller 142A.

In the operation of the coating apparatus 100, the edge of the glass G can be processed through a polishing process. At this time, the sharp portion of the edge region of the glass (G) can be removed through the polishing process.

The glass G can be provided in the fixing portion 162 first. The linear driving unit 180 is operated to bring the position of the glass G into contact with the second roller 142A so that the glass supporting frame 161 can move up and down.

When the position of the glass G is determined, the edge region of the glass G can be heated through the curing portion 191 while the rotation driving portion 163 is operated. For example, when the curing portion 191 is operated, the edge of the glass G may be irradiated with infrared rays, so that the temperature of the glass G may rise.

At this time, when the curing portion 191 heats the rim of the glass (G), the surface tension can be lowered. Particularly when the chemical liquid C is applied to the glass G, the chemical liquid C can move too much to the surface of the glass G due to the surface tension between the glass G and the chemical liquid C. However, by heating the edge of the glass (G) through the curing portion 191 as described above, the thickness T of the desired chemical solution C and the length S of the chemical solution C applied to the flat surface of the glass G Can be adjusted.

The rotation driving unit 163 can be operated again after the curing unit 191 is operated. When the rotation drive portion 163 is operated, the glass G rotates and the glass G contacts the second roller 142A to rotate the second roller 142A. By the rotation of the second roller 142A, The first roller 141A can be rotated.

At this time, the rotation measuring unit 195 can measure the rotation speed of the first roller 141A. The measured rotational speed of the first roller 141A can be transmitted to a control unit (not shown). The control unit may control the linear driving unit 180, the rotation driving unit 163, and the like. At this time, the control unit may include a general circuit board type, a personal computer, a notebook computer, a mobile phone, and the like.

The controller can adjust the rotational speed of the glass G and the position of the glass G based on the measured rotational speed of the first roller 141A. More specifically, the controller may control the rotation driving unit 163 such that the rotation speed of the glass G becomes the second rotation speed when the rotation speed of the first roller 141A is equal to the predetermined first rotation speed. In addition, the controller may operate the linear driving unit 180 such that the glass G linearly moves when the rotational speed of the first roller 141A is equal to the predetermined first rotational speed. In particular, since the glass G is a rectangular shape rather than a square, the control unit can control the linear driving unit 180 to correspond to the shape of the glass G. [

At this time, the controller may control the linear driving unit 180 and the rotation driving unit 163 such that the rotational speed of the first roller 141A is constant. For example, when the rotation speed of the first roller 141A is less than the predetermined first rotation speed, the control unit controls the rotation driving unit 163 to rotate faster or the contact between the glass G and the second roller 142A The linear driving unit 180 can be controlled to be looser than the initial level.

On the other hand, when the rotational speed of the first roller 141A exceeds a predetermined first rotational speed, the control unit controls the rotation drive unit 163 to rotate more slowly or contacts the glass G and the second roller 142A The linear driving unit 180 can be controlled to be closer to the initial level than the initial level.

The control unit may control the rotation driving unit 163 and the linear driving unit 180 so that the rotation speed of the first roller 141A is equal to the predetermined first rotation speed.

The control unit can control the thickness T and uniformity of the chemical liquid C applied to the rim of the glass G to be constant by controlling the rotation driving unit 163 and the linear driving unit 180. [ In addition, the control unit can control the linear velocity between the glass G and the second roller 142A of various shapes or shapes to be constant through the above-described control. That is, the controller can control the thickness T of the chemical liquid C applied by controlling the degree of contact between the glass G and the chemical coating unit 140 by controlling the linear driving unit 180. In addition, the control unit controls the rotation speed of the rotation driving unit 163 so that the chemical liquid C is uniformly applied to the glass (G).

The above operation can be continuously performed while the glass G is rotating. The rotation speed of the glass G and the position of the glass G can be varied in accordance with the rotation speed of the first roller 141A measured by the rotation measuring unit 195. [ In addition, the control as described above can control the rotational speed of the first roller 141A to have a constant value.

Therefore, by synchronizing the rotational speed of the first roller 141A with the rotational speed of the glass G and the position of the glass G, the coating apparatus 100 can uniformly disperse the chemical liquid C on the rim of the glass G, Can be applied.

When the glass G is rotated as described above, the chemical liquid C is transferred to the second roller 142A through the first roller 141A, and the edge of the glass G, which is in contact with the second roller 142A, And the chemical liquid (C) can be coated on the corners.

When the glass G is rotated as described above, the glass G is formed in a rectangular shape, so that the distance between the rotation center of the second roller 142A and the rim of the glass G can be variable. At this time, the shape of the glass G is not limited to the above, and may be a polygon such as a square, a triangle, etc., an ellipse, or a circle. Hereinafter, for convenience of explanation, the case where the shape of the glass G is rectangular will be described in detail.

The movable block 120 can move linearly according to the distance between the rotation center of the second roller 142A and the rim of the glass G. [ Specifically, when the distance between the center of rotation of the second roller 142A and the rim of the glass G increases from the initial value, the movable block 120 can move to the right in Fig. At this time, the bearing part 150 separates the moving block 120 from the first supporting frame 111, thereby removing the frictional force between the first supporting frame 111 and the moving block 120 when the moving block 120 moves can do. On the other hand, when the distance between the rotation center of the second roller 142A and the rim of the glass decreases from the initial value, the movable block 120 can move to the left side of Fig. At this time, the bearing part 150 can smoothly move the moving block 120.

The balancing unit 170 may move the moving block 120 to the left side of FIG. 1 while the moving block 120 moves. Specifically, when the distance between the center of rotation of the second roller 142A and the rim of the glass increases and decreases from the initial value, the balancing portion 170 moves the moving block 120 to the left in FIG. Can be moved in the left direction in Fig. Particularly, the weight of the weight 173 can be transferred to the moving block 120 by the cable 171 to move the moving block 120. The above process can be continuously performed in the process of coating the edge (C) of the glass (G) with the chemical solution (C), and the weight (173) can be removed after the process is completed. The operation of the air bearing 152 may be stopped instead of removing the weight 173 as another embodiment. At this time, when the air bearing 152 is stopped, the moving block 120 is seated on the guide portion 151, so that the movement of the moving block 120 can be stopped. Particularly, in such a case, frictional force may be applied between the moving block 120 and the guide portion 151.

The moving block 120 is moved in a no-load state while controlling at least one of the rotation driving unit 163 and the linear driving unit 180 through the control unit as described above to move the glass block G and the second roller 142A in real time The contact pressure on the contacting surface can be uniformly adjusted.

Particularly when glass G is machined, there is a possibility that a machining error occurs or a mounting position accuracy distribution is generated due to a loading failure that may occur due to a difference in position fixed to the fixing portion 162, The contact pressure between the coating liquid G and the chemical coating portion 140 and the coating speed of the chemical liquid C can be constantly regulated.

Accordingly, the coating apparatus 100 can apply a uniform chemical liquid C to the edge of the glass G through the above-described operation. In addition, the coating apparatus 100 can prevent excessive pressure from being applied to the edge of the glass (G), thereby preventing the edge portion of the glass (G) from being damaged.

On the other hand, when the chemical solution C is applied to the edge region of the glass G as described above, the curing portion 191 can irradiate the edge of the glass G with infrared rays. At this time, the curing portion 191 can harden the chemical liquid C applied to the rim of the glass (G).

The chemical liquid C to be cured as described above may have a certain thickness. For example, the maximum distance (T) from the edge of the glass (G) to the outside of the cured medicinal liquid (C) may be 15um or more and 25um or less. At this time, the rim of the glass (G) may be formed into a curved surface through the polishing process as described above.

If the thickness of the chemical liquid (C) is less than 15 탆 as described above, the rim of the glass (G) can not be sufficiently strengthened, so that the rim of the glass (G) may be damaged or damaged by external force. Further, when the thickness of the chemical liquid C is more than 25 mu m, it may not be possible to form a desired angle when bending or bending the glass G after forming a fine structure on the glass G. [

The distance from the edge of the edge of the glass G to the exterior of the medicinal liquid C hardened at the center of the rim of the glass G may be the maximum distance T. [ Further, the thickness of the chemical liquid C can be made smaller toward the edge of the glass (G) along the rim of the glass (G) from the central portion of the rim of the glass (G).

On the other hand, the chemical liquid (C) applied to the edge region of the glass (G) can be applied to the flat portion of the glass (G). In particular, in the above case, the chemical liquid C may rise up to the flat portion of the glass G in the edge region of the glass G due to the capillary phenomenon or the like.

At this time, the length S of the chemical liquid C formed on the flat part of the glass G may be 50um or less. In this case, when the length S of the chemical liquid C exceeds 50 mu m, the area for forming the structure on the glass G may be small. Particularly, when a display portion for forming an image on the outside is formed on the glass G such as an organic light emitting display or the like, the size of the display portion may be reduced and the merchantability may be deteriorated. In addition, when the length S of the medicinal liquid C is too large, the display portion is formed on the medicinal liquid C, so that the display portion is bent due to the medicinal liquid C, which may deteriorate visibility.

The coating apparatus 100 can quickly and accurately coat the glass G with the chemical agent C by moving the movable block 120 according to the rotation of the glass G regardless of the form of the glass G. [

The coating apparatus 100 can prevent the rim or corners of the glass G from being broken by coating the chemical liquid C by moving the movable block 120 according to the rotation of the glass G. [

The coating apparatus 100 can uniformly spray the chemical liquid C by uniformly supplying the chemical liquid C to the glass G. [

FIG. 5 is a conceptual view showing another embodiment of the chemical coating portion shown in FIG. 1. FIG.

Referring to FIG. 5, the chemical coating portion 140B may include a first roller 141B, a second roller 142B, and a distance control bracket 143B. At this time, the first roller 141B is the same as or similar to the first roller 141A described with reference to FIGS. 1 and 2, and a detailed description thereof will be omitted.

The second roller 142B comes into direct contact with the glass G to supply the chemical G to the glass G or to contact the first roller 141B to remove a part of the chemical solution C of the first roller 141B Can play a role. At this time, when the second roller 142B removes a part of the chemical solution C of the first roller 141B, the glass G can be supplied with the chemical solution C by contacting the first roller 141B. Hereinafter, the second roller 142B and the glass G are in contact with each other for convenience of explanation.

The first roller 141B and the second roller 142B may be rotatably mounted on the distance control bracket 143B. At this time, the distance adjustment bracket 143B may be installed to connect the rotation center of the first roller 141B and the rotation center of the second roller 142B. In particular, the distance control bracket 143B may be installed to be connected to the movable block 120.

The distance adjustment bracket 143B may adjust the distance between the rotation center of the first roller 141B and the rotation center of the second roller 142B. Specifically, the distance adjustment bracket 143B may have a plurality of holes or slots, and the first roller 141B and the second roller 142B may be installed at various positions in the plurality of holes or slots.

The distance adjusting bracket 143B adjusts the distance between the center of rotation of the first roller 141B and the center of rotation of the second roller 142B so that the chemical solution C adsorbed on the surface of the second roller 142B Can be adjusted. For example, when the distance between the center of rotation of the first roller 141B and the center of rotation of the second roller 142B is made to approach, the surface of the first roller 141B and the surface of the second roller 142B The chemical solution C of the first roller 141B can be attracted to the second roller 142B more when the second roller 142B rotates. On the other hand, when the distance between the center of rotation of the first roller 141B and the center of rotation of the second roller 142B is made to be distant, the amount of the chemical liquid C adsorbed to the second roller 142B can be reduced.

Therefore, the coating apparatus 100 can quickly and easily adjust the amount of the chemical liquid C supplied by adjusting the distance between the first roller 141B and the second roller 142B.

FIG. 6 is a conceptual view showing still another embodiment of the chemical coating portion shown in FIG. 1. FIG.

6, the chemical coating portion 140C includes a chemical liquid supply roller 141C rotatably installed on the movable block 120, a blade 142C disposed on the movable block 120 and contacting the chemical liquid supply roller 141C, And a portion 144C. At this time, the chemical liquid supply roller 141C is the same as or similar to the first roller 141B or the second roller 142B described with reference to FIGS. 1 and 2, and thus a detailed description thereof will be omitted.

The blade portion 144C can partially remove the chemical liquid adsorbed on the surface of the chemical liquid supply roller 141C by making contact with a part of the surface of the chemical liquid supply roller 141C. Particularly, the blade portion 144C removes a part of the chemical liquid C adsorbed on the surface of the chemical liquid supply roller 141C before the chemical liquid supply roller 141C comes into contact with the glass G, (C).

The blade 144C may be installed to be movable to the moving block 120. [ For example, the blade portion 144C can be moved such that the distance between the end of the blade portion 144C and the surface of the chemical liquid supply roller 141C is variable. At this time, a distance adjusting part 145C for moving the blade part 144C may be connected to the blade part 144C.

The distance adjuster 145C may include a cylinder changer having a variable length. In another embodiment, the distance adjusting unit 145C may include a ball screw that varies in position with rotation and a motor that is connected to the ball screw to rotate the ball screw. In another embodiment, the distance adjusting portion 145C may include a ball screw. In this case, the distance adjusting portion 145C is not limited to the above, and may include all the devices and all structures that are connected to the blade portion 144C to vary the position of the blade portion 144C. Hereinafter, for convenience of description, the distance adjusting unit 145C will be described in detail with reference to a case where a length-variable cylinder liner is provided.

The operation of the chemical coating unit 140 may be such that the chemical liquid supply roller 141C rotates as the glass G rotates. At this time, the distance adjusting section 145C may be operated to move the blade section 144C such that the distance between the blade section 144C and the surface of the chemical supply roller 141C is equal to the predetermined distance.

Then, when the chemical liquid supply roller 141C is rotated and the chemical liquid is adsorbed on the surface of the chemical liquid supply roller 141C, it can be supplied to the glass G with part of the blade portion 144C removed.

If it is determined that the amount of the chemical liquid C to be coated is large during the above operation, the distance adjusting unit 145C may be provided so that the distance between the blade 144C and the surface of the chemical liquid supply roller 141C is closer to the initial value. Lt; / RTI > On the other hand, it is determined that the amount of the chemical liquid C coated on the glass G is small, and that the distance between the blade 144C and the surface of the chemical liquid supply roller 141C becomes larger than the initial value, Can be operated.

Therefore, the coating apparatus 100 can uniformly coat the chemical liquid C on the glass G by controlling the amount of the chemical liquid C easily and quickly.

Further, since the coating apparatus 100 can supply the chemical liquid C to the glass G through a simple structure, the coating apparatus 100 can be manufactured easily and can be operated easily.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover all such modifications and variations as fall within the true spirit of the invention.
