1 to 3, a coating device 300 according to an embodiment of the present invention includes a support 310, a rotation driving device 320, and a rotation driving device 320 And a main body 330 connected to the rotating shaft 332. The coating device 300 of this embodiment is a device for applying the glue 200 to the object 100. [

The support 310 has a support surface 311, an outflow passage 312, a seating groove 313, and a side wall 314. 1 (a) and 1 (b), the support surface 311 supports the object 100 from the lower side such that one side of the object 100 faces upward. The support surface 311 may form a seating groove 313 together with the side wall 314 protruding to surround the object 100. [

The seating groove 313 becomes a space in which the residual glue 200 which is not used for coating around the object 100 flows down. The remaining glue 200 does not remain on one surface of the object 100, and a coating layer having a uniform thickness can be formed up to the edge of one surface of the object 100. In addition, when the remaining glue 200 occupying the mounting groove 313 flows out to the outside through the outflow passage 312, a coating layer having a more uniform thickness can be formed. The side wall 314 may function to prevent the glue 200 flowing down from one surface of the object 100 from overflowing the support 310.

The support 310 may have a locking protrusion 315 as shown in FIG. 1 (c). The latching jaw 315 is formed so as to surround at least a part of the object 100 in the receiving groove 313. The outer surface of the latching jaw 315 may be formed obliquely, and preferably has a curvature as shown in Fig. 1 (c).

The hooking jaw 315 not only functions to hold the position of the object 100 but also allows the remaining glue 200 to easily flow along the outer side having a curvature after the application and does not remain on one surface of the object 100 It is possible to smoothly discharge the gas to the outflow passage 312. In addition, it is possible to prevent the residual glue 200 from being caught on the side surface of the object 100 by the catching jaw 315.

A vacuum hole is formed in the support surface 311 of the support body 310 but a negative pressure is formed by the vacuum pump connected to the vacuum hole to support the object 100 on the support surface 311, As shown in Fig.

The outlet passage 312 is preferably located near the side wall 314, since its inlet must be located at a location that does not overlap the object 100. In other words, the outflow passage 312 is preferably located at the edge of the support surface 311. The outflow passage 312 serves to flow out the glue 200 which is not used for coating but flows down (refer to (b) and (c) of FIG. 3). Therefore, the glue 200 can be reused and the glue 200 can be prevented from being wasted by forming the outflow passage 312 in the support 310.

1 (b), the outflow passage 312 may provide only the flow path of the glue 200. However, in order to discharge the glue 200 more smoothly, as shown in FIG. 1 (c) 312 may be further provided with a separate vacuum pump 316 to form a negative pressure. Various vacuum pumps known in the art may be used as the vacuum pump 316 and the vacuum pump 316 may be located outside the support 310 and communicate with the outlet passage 312 through a tube.

The rotary drive device 320 is connected to the rotary plate 331 by a rotary shaft 332. The main body 330 to be described later receives the driving force provided by the rotation driving device 320 by the rotation shaft 332 and rotates clockwise or counterclockwise.

As the rotation driving device 320, a motor may be employed. As the motor, a DC motor, an induction motor, a synchronous motor, an AC commutator motor, or the like may be used. Among them, the synchronous motor rotates at a constant speed and is easy to adjust the power factor and is suitable as the rotation driving device 320 of the coating device 300 of the present embodiment. The rotation drive device 320 is not limited to the above-described kind, and various known rotation drive devices can be used.

The main body 330 has a rotating plate 331, a rotating shaft 332, a nozzle 333, and a squeegee 335 as shown in Figs.

The rotary plate 331 is generally in the form of a circular plate. A rotary shaft 332 is positioned on the upper surface of the rotary plate 331 and the rotary drive device 320 is connected to the upper end of the rotary shaft 332. The rotation driving device 320 may be connected to the rotating plate 331 by using a mechanical element such as a belt or a chain. .

A nozzle 333 and a squeegee 335 are disposed on the lower surface of the rotary plate 331. The nozzle 333 supplies the glue 200 to the object 100 and the squeegee 335 scours the supplied glue 200 to uniformly apply the glue 200 to the object 100.

The nozzle 333 is formed with a discharge port 334 toward the one surface of the object 100 at the lower end thereof for discharging the glue 200 to one surface of the object 100. Such a discharge port 334 may have a circular shape as shown in FIG. 2, but it is preferable that the discharge port 334 has a slit shape as shown in FIG. 4 (a) when discharging the glue 200 uniformly over a large area. The nozzle 333 may be provided as shown in FIG. 2. However, in the case of discharging the glue 200 uniformly over a wide area, the glue 200 may be separated from the object 100 by two or more sub- As shown in FIG. The arrangement and number of the nozzles 333 and the shape of the ejection openings 334 can be changed according to the shape of one surface of the object 100 to which the glue 200 is applied, which also falls within the scope of the present invention.

The squeegee 335 protrudes from the bottom of the rotary plate 331 and has a protruding end portion 336 formed elongated. The protruding end portion 336 contacts the glue 200 supplied from the nozzle 333 to form a coated surface 201. It is preferable that the squeegee 335 is formed so that the protruding end portion 336 of the squeegee 335 forms a flat surface when the main body 330 is rotated to form the uniform coated surface 201. 2 and 3, the protruding end portion 336 of the squeegee 335 forms a straight line perpendicular to the rotation direction and is formed to be long from the center to the edge of the rotation plate 331.

The squeegee 335 squirts the glue 200 as shown in FIG. 3 (b), and the glue 200 is applied as much as the space between the projecting end 336 and the object 100. 3 (c), it is preferable that one side of the object 100 and the projecting end 336 of the squeegee 335 are configured to be parallel to each other to form a coating layer having a constant thickness . The shape of the protruding end portion 336 of the squeegee 335 is determined comprehensively according to design specifications such as which coating surface 201 is to be formed on one surface of the object 100 and thickness of the coating layer .

The nozzles 333 and the squeegees 335 are arranged such that the nozzles 333 supply the glue 200 to one surface of the object 100 and then the rotary plate 331 rotates so that the squeegees 335 form the application surface 201 . At this time, shortening the time interval between the supply and the squigging of the glue 200 from the nozzle 333 can prevent the curing of the glue 200 exposed on the surface, thereby forming a more uniform application surface 201 Do. Therefore, the gap between the nozzle 333 and the squeegee 335 is preferably small.

The height of the squeegee 335 may be adjusted to adjust the thickness and shape of the object 100 and the thickness of the glue 200 to be coated. The squeegee 335 itself may be moved up and down from the main body 330 to adjust the height of the squeegee 335 and the squeegee 335 may be fixed to the rotating plate 331 and the rotating plate 331 itself may be moved up and down The elevation of the squeegee 335 may be adjusted while moving. With the above-described configuration, the application device 300 can be applied to various types of objects 100, and various types of application layers can be formed, and utilization can be increased.

The main body 330 may hold the glue 200 to a certain extent or may receive the glue 200 from an external supply source.

Hereinafter, the operation of the above-described application device 300 will be described with reference to FIG.

First, the object 100 is placed on the support surface 311 of the support 310 and the main body 330 is disposed on the support 310 in such a manner that the lower surface of the main body 330 faces the support 310 .

3 (a), the glue 200 is supplied to one surface of the object 100 by using the nozzle 333 located in the main body 330. At this time, the glue 200 may be supplied while rotating the main body 330 using the rotation driving device 320, or the glue 200 may be supplied while the main body 330 is stopped.

When discharging the glue 200 is completed, the main body 330 is rotated to squeegee the glue 200 by the squeegee 335 as shown in FIG. 3 (b). The projecting end 336 of the squeegee 335 forms a coated surface 201 on one surface of the object 100. [ After the application, the remaining glue 200 flows down from the object 100 and the remaining glue 200 flows out to the outside through the outflow passage 312 formed in the support 310 as shown in FIG. 3 (c). Here, it is preferable to maintain the rotation speed of the main body 330 at the time of squeezing constantly for the formation of the coated surface 201.

On the other hand, since the glue 200 flowing from the object 100 may remain on the surface other than the surface of the object 100, a separate post-process for removing the remaining glue 200 may be performed. This post-process may be performed while the object 100 is supported on the support 310, or may be performed separately from the support 310.

On the other hand, the squeegee may have a convex shape in the rotational direction as shown in Fig. The use of such a curved squeegee 335 'pushes the glue 200 in the direction of rotation while pushing the glue 200 laterally in the direction of rotation as well, It is possible to prevent it from being driven only in the direction.

As shown in FIG. 6, the nozzles 333a and 333b and the squeegees 335a and 335b may be alternately provided at least two times. 6, the glue can be applied to the two objects even with the half-turn of the main body 330, and the productivity can be improved. Alternatively, the nozzle 333a and the squeegee 335a may apply the glue primarily to one surface of the object and once again apply the application surface 201 on which the nozzle 333b and the squeegee 335b are applied first, The imperfections that may occur in the applied coating layer are eliminated, and a more uniform coated layer can be formed.

The object 100 may be a display panel or a protective glass if the application device 300 of the present invention is utilized in the manufacture of a flat panel display. And the glue 200 may be a transparent glue for optics suitable for manufacturing flat panel displays.

According to the above-described coating device 300, the apparatus can be configured with a simple structure as compared with the linear transfer apparatus, so that the facility cost can be minimized. Further, by implementing a more stable coating process, it is possible to form a coating layer having a uniform thickness to the edge of one side of the object. In addition, unnecessary waste of the glue 200 is prevented by reusing the remaining glue 200 that is not used for application.

In addition, when the coating process by the coating device 300 is completed, the temporary hardening process, the adhesion process, and the final curing process of the coating layer proceed sequentially. Here, the coating layer is maintained at a constant thickness by the provisional curing process. The adhesion process is preferably performed in a vacuum environment in order to prevent the formation of bubbles generated during the cementation and to improve the spreadability of the cured coating layer, and thus the yellowing phenomenon due to the unevenness of the coating layer may be improved . The remaining hardening process, the lapping process, and the final hardening process may be performed by known methods, and thus a detailed description thereof will be omitted.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
