The present invention relates to a device for attaching a reinforcement glass to a planar color cathode ray tube, and more particularly, to reduce a defective rate by changing a structure to automatically attach a reinforcement glass to a panel surface of a cathode ray tube. In addition, the production cost can be reduced. In general, color cathode ray tubes are used in television receivers and various monitors to reproduce color screens by emitting red, green, and blue phosphors by video signals (luminance signals and color signals). As shown in FIG. 1, a), the shape of the panel is integrated with a panel 1 and a funnel 3 having a neck 2 rearwardly. (Bulb form), the neck portion 2 has an electron gun (4) is installed in the neck portion 2 to emit red, green, blue three-color electron beam, the electron gun (4) on the outer peripheral surface of the neck portion of the panel A deflection yoke 5 is provided to deflect the electron beam emitted in the horizontal and vertical directions, and a frame 6 is supported by a plurality of support springs 7 inside the panel 1. In addition, a shadow mask 8 is formed on the side of the panel 1 of the frame 6, in which numerous small holes in the shape of dots are drilled so that the electron beam emitted from the electron gun 4 passes. The panel of the frame 6 is fixed. On the (3) side, an inner shield (9) is fixed to prevent the electron beam emitted from the electron gun (4) from being deformed by a geomagnetic field or a leakage magnetic field, and a shadow mask is provided on the inner side of the panel (1). The phosphor 10 is applied so that an image is formed when the electron beam which has passed through (8) strikes. Therefore, when a high pressure is applied to the electron gun 4 in the neck portion 2 formed in the funnel 3, the electron gun is activated to emit a three-color electron beam, and the emitted electron beam is the outer peripheral surface in front of the neck portion 2 of the funnel 3. The deflection yoke 5 is deflected in the horizontal and vertical directions by the magnetic field of the deflection yoke 5, wherein the inner shield 9 fixed to the funnel 3 side of the frame 6 is continuously discharged in a deflected state. The magnetic field and the leakage magnetic field are prevented so that the path of the electron beam is not deformed along the way. On the other hand, a part of the electron beam emitted from the electron gun 4 passes through each hole of the shadow mask 8 fixed to the panel 1 side of the frame 6 and is applied to the inner surface of the panel 1 with a phosphor 10. ), The color screen is reproduced by the combination of the three-color electron beams. As described above, steel has a curvature of the panel surface of a general color cathode ray tube, so that the main surface of the panel is reinforced with a band of steel in order to achieve explosion-proof characteristics. As shown in FIG. 2), a flat color cathode ray tube having a flat panel surface is developed and used, and since the flat color cathode ray tube uses a completely flat panel as described above, in order to obtain explosion-proof characteristics, Instead of a band made of glass panel reinforcement was attached by a separate device. FIG. 2 is a perspective view showing a reinforcement glass attachment device of a conventional flat color cathode ray tube, and FIG. 3 is an enlarged cross-sectional view showing a state in which a reinforcement glass is attached to a panel surface by a conventional device. A plurality of ultraviolet lamps 13 are installed on the plate 12, and a fixing frame 14 is hinged to one side of the plate 12 so as to be rotatable, and a reinforcement glass 15 is provided inside the fixing frame. The support 16 and the gasket 17 are integrally fixed to support the support bracket, and the fixing bracket 14 is fixed to the outside of the fixing frame 14 to fix a flat color cathode ray tube (hereinafter referred to as a cathode ray tube). 18) is installed structure. The height of the gasket 17 is necessarily higher than the height of the reinforcing glass 15 to be attached to the panel surface of the cathode ray tube.

Therefore, the fixed frame 14 hinged to one side of the upper plate 12 of the main body 11 is rotated horizontally with the plate 12 and then the reinforcement glass 15 is fixed to the inside of the fixed frame 14 When pushed into the gasket 17, the reinforcement glass 15 is supported by the support 16 fixed to the inside of the frame 14 together with the gasket 17. On the other hand, when the reinforcement glass 15 is supported, the color cathode ray tube may be placed on the fixing frame 14, and then the color cathode ray tube may be fixed by a pair of fixing brackets 18 installed on the fixing train. Since the panel constituting the cathode ray tube is in contact with the fixing frame 14, a space portion is formed between the reinforcing glass 15 and the panel. The space between the reinforcement glass 15 and the panel of the color cathode ray tube may be formed because the height of the gasket 17 fixed inside the fixing frame 14 is higher than the height of the reinforcement glass 15. Do. When the reinforcement glass 15 is supported in this way and the color cathode ray tube is fixed, the fixing frame 14 in a horizontal state with the plate 12 is rotated again as shown in FIG. When the pump (not shown) is operated, the ultraviolet curable resin is injected into the space portion between the reinforcing glass 15 and the panel of the color cathode ray tube through the resin suction port. When the fixed frame 14 is rotated horizontally with the plate 12 again, the ultraviolet ray lamp 13 installed on the plate lights up and emits ultraviolet rays, so that the ultraviolet curing resin is cured by the emitted ultraviolet rays. Reinforcement glass 15 is attached to the color cathode ray tube. However, such a device conventionally has an injection part (between tempered glass and a panel of color cathode ray tube) for injecting the UV curable resin and a plastic part for curing the UV curable resin injected into the injection part. Dust or other foreign matter was mixed in the ultraviolet curing resin attaching the reinforcement glass to the panel, thereby reducing the adhesive force of the reinforcement glass, thereby increasing the defective rate. In addition, since the injection portion and the plastic portion are each composed of a separate system, there is a problem that the production cost increases due to the increase in the labor time and the labor time. The present invention has been made in order to solve the above problems, the supply part for supplying the ultraviolet curable resin to the panel surface of the cathode ray tube and the plastic part for curing the injected ultraviolet curable resin supplied by the supply in the chamber As it prevents dust or other foreign matter from being mixed into the UV curing resin during work, it reduces the defect rate by improving adhesion of reinforcement glass and all work is done automatically, thus saving work time and labor cost.

A discharge pump 30 for discharging the ultraviolet curable resin to the outside, and a guide hose 31 for guiding the ultraviolet curable resin discharged in connection with the discharge pump to the panel 1 surface of the cathode ray tube. do.

The reinforcement glass supply means is attached to the other side wall in the chamber 22 to drive the motor 32 under the control signal of the controller 25 and the moving side coupled to the motor to receive the driving force of the motor 32 to move vertically. (33), a plate (34) fixed to the end of the moving shaft to support the plurality of reinforcement glass, and a plurality of reinforcement glass (24) attached to the other side wall in the chamber (22) and supported by the plate (34). When the top of the reinforcement glass is vertically moved upward by a certain height is completed, the sensor 35 is configured to sense this and block the control signal of the controller transmitted to the motor 32. The reinforcing glass conveying means includes an upper guide rail 36 fixed in the chamber 22, an upper movable body 37 mounted on the upper guide rail and horizontally moving under the control signal of the controller 25, and the upper movable body of the upper movable rail. The compressor 38 attached to one side generates air while operating under the control signal of the controller 25, and the air generated from the compressor 38 attached to the lower side of the upper movable body 37 to generate a first air. The air cylinder 39 is selectively supplied through the air hose 38a and the second air hose 38b, and is fixed to the cylinder rod 39a of the air cylinder to receive and reinforce the control signal of the controller 25. It consists of the vacuum adsorption machine 40 which adsorb | sucks the glass 24. The ultraviolet irradiation means is installed in the lower guide rail 41 fixed in the chamber 22, the lower movable body 42 which is installed on the lower guide rail and moves horizontally in response to a control signal of the controller 25, and the lower movable body. It is composed of an ultraviolet lamp 43 that is supplied with power to generate ultraviolet light. Referring to the operation and effects of the present invention configured as described above are as follows. First, the cathode ray tube is supported on the pedestal 28 constituting the cathode ray tube support means as shown in FIG. 4 a), and the tank 29 constituting the ultraviolet ray cured resin supply means is filled with the ultraviolet ray cured resin, and the reinforcing glass supply means is provided. A plurality of reinforcing glass 24 is laminated on the plate 34 to be configured, and then the spacing member 23 is placed on the edge of the panel surface of the cathode ray tube supported by the pedestal 28. When the above operation is finished, selecting the start button (not shown) of the selection buttons of the controller 25 attached to the main body 21, the discharge pump 30 constituting the ultraviolet curing resin supply means is the controller 25 Drive under the control signal to discharge the ultraviolet curable resin filled in the tank 29, and the ultraviolet curable resin discharged is guided along the guide hose 31 connected to the discharge pump 30, and then the panel surface of the cathode ray tube. Supplied until. In this way, when a certain amount of UV curable resin is supplied to the panel surface of the cathode ray tube, the discharge pump 30 is stopped and a plurality of driving bodies 26 constituting the cathode ray and the support means are controlled by the controller 25. Since the driving bar 27 installed in each of the driving bodies 26 are alternately moved in and out of each other, and the cathode ray tube supported by the pedestal 28 flows forward, backward, left and right. The ultraviolet curable resin supplied to the panel surface of the cathode ray tube is uniformly applied to the entire portion of the panel surface at the same thickness as the thickness of the space keeping member 23. In the above, the spacing member 23 is placed on the edge of the panel surface of the cathode ray tube in order to apply the UV curable resin to the panel surface so that the UV curable resin is applied to a certain thickness and not flow down at the same time. In order to remove the gap 23, the urethane-based non-adhesive rubber is mainly used. When the UV light resin is evenly applied to the panel surface of the cathode ray tube, the motors 32 are driven under the control signal of the controller 25 at the same time as the respective driving bodies 26 are stopped. The moving shaft 33 installed in the upper part is moved to the upper end and thus fixed to the end of the moving shaft, the plate 34 in which a plurality of reinforcing glass 24 is laminated is also moved upward with the moving shaft 33. When the uppermost reinforcement glass is positioned on the same horizontal line as the sensor 35 attached to the other side wall in the chamber 22, the sensor detects the reinforcement glass 24 and transmits it to the motor 32. The control signal is cut off and thus the driving of the motor 32 is stopped, so that one reinforcement glass is supplied to a certain height. When the reinforcement glass 24 is supplied to a certain height, the vacuum adsorber 40 constituting the reinforcement glass transfer means operates under the control signal of the controller 25 to operate the reinforcement glass 24 supplied by the reinforcement glass supply means. At the same time, the upper movable body 37 is operated by receiving the control signal of the controller 25 to move horizontally to the right side in the drawing to the position opposite the cathode ray tube along the upper guide rail 36, and the upper movable body 37 When the horizontal movement is completed, the compressor 38 attached to one side of the upper movable body is operated under the control signal of the controller 25 to operate the air cylinder attached to the lower side of the upper movable body 37 through the first air hose 38a. Since air is supplied to the 39, the air cylinder 40 fixed to the end of the cylinder rod and adsorbing the reinforcing glass 24 moves downward as the cylinder rod 39 a is pulled out downward. When the vacuum adsorber 40 is moved to the bottom as described above, since the operation of the vacuum adsorber is stopped, the reinforcing glass 24 is separated from the vacuum adsorber 40 and is in contact with the ultraviolet curable resin applied to the panel surface of the cathode ray tube. At this time, since the air generated from the compressor 38 is supplied to the air cylinder 39 through the second air hose 38b, the vacuum rod 40 also moves as the cylinder rod 39a enters the air cylinder 39 again. The upper movable body 37 is moved to the upper side again and is guided to the upper guide rail 36 in response to the control signal of the controller 25 to move horizontally to the left in the drawing to convey the next reinforcement glass 24. In the state in which the reinforcing glass 24 is in contact with the ultraviolet curable resin applied to the panel surface of the cathode ray tube, the interval between the reinforcing glass 24 and the panel of the cathode ray tube is maintained by a spacing member 23. Height of the member). On the other hand, when one of the reinforcing glass 24 is transferred to the panel surface of the cathode ray tube by the reinforcing glass conveying means is operated by receiving the control signal of the controller of the lower movable body 42 constituting the ultraviolet irradiation means to operate the lower guide rail 41 Accordingly, when the lower movable body 42 comes to a position facing the cathode ray tube, the lower movable body is stopped and the ultraviolet lamp 43 installed in the lower movable body 42 is turned on for a predetermined time. As the ultraviolet rays are irradiated to the reinforcing glass 24 transferred to the panel surface of the cathode ray tube, the UV curable resin between the reinforcing glass and the panel is cured by receiving ultraviolet rays, so that the reinforcing glass 24 is completely attached to the cathode ray tube. do. After all the above steps, when the reinforcing glass 24 is attached to the cathode ray tube, the lower movable body 42 constituting the ultraviolet ray irradiation unit is horizontally moved back to its original state, and then the gap placed on the edge of the panel surface of the cathode ray tube The maintenance member 23 is removed to finish all the work.

It is to be understood that the present invention described so far describes the cycle as long as the reinforcing glass 24 is attached to the panel surface of the cathode ray tube. Therefore, in the present invention, since the supply part for supplying the UV curable resin to the panel surface of the cathode ray tube and the plastic part for curing the UV curable resin supplied by the supply part are embedded in the chamber, the foreign material penetrates into the UV curable resin. As it is not possible to reduce the adhesion failure rate of the reinforcement glass significantly, as well as each step of attaching the reinforcement glass to the cathode ray tube is automatically performed, there is also the effect of reducing the production cost according to saving work time and labor costs.
