Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent film forming system for a CRT panel formed on the inner surface of an effective screen of a display device (hereinafter simply referred to as "CRT panel") using a cathode ray tube.

[0002]

2. Description of the Related Art In a CRT panel using a color cathode ray tube, a color filter or an R
Phosphors containing pigments (red), G (green), and B (black) are coated. In the production of this phosphor screen, a production method called "thriller method" is generally adopted.

A brief description will be given of the procedure for making the "thriller method". (1) First, R, G, B are placed in a CRT panel having a carbon stripe formed on the inner surface of curvature.
A sufficient amount of liquid containing each phosphor is injected for each color, and the CRT panel is rotated to uniformly apply the phosphor on the entire effective screen. (2) After that, the aperture grill paired with each CRT panel is set, the exposure and development processes are performed, and the liquid other than the necessary portions is removed by washing. This process is performed once for each color of R, G, and B, for a total of three times, and then an intermediate film for flattening the coated stripe is formed. (3) Next, a metal back such as a metal aluminum film is vapor-deposited on the entire effective screen for the purpose of improving the brightness due to the mirror surface effect and preventing ion burning. This completes the formation of the phosphor screen.

[0004]

However, the method of forming the fluorescent screen in the color cathode ray tube using the above-mentioned thriller method has the following problems (1) to (5). (1) The process is complicated, and various types of single-function devices such as a washing machine, a dryer, an exposure table, a frit coating machine, and an aperture grill attaching / detaching machine are required. (2) One device is required for each coating liquid, and new equipment is required each time the used liquid increases. For example, if a carbon stripe is used, at least two solutions will be added, and two devices will be added accordingly. (3) Since the pigment-based phosphor liquid is used, aggregation,
Sufficient liquid management is required to prevent settling, which complicates management. (4) Since a large amount of liquid is used in production, purification equipment for collecting and regenerating the liquid is also required, which complicates the equipment. (5) Since it is a multi-step process, management between processes is required, and the overall management becomes complicated.

The present invention has been made in view of the above problems, and an object thereof is to construct a dry-type phosphor producing system to simplify the production equipment and the like, to reduce the cost and provide it at a low cost. (EN) Provided is a phosphor production system for a CRT panel. In addition, the other purpose is

FIG. 7 is an operation state diagram of the fluorescent film forming apparatus, and FIG. 8 is a flowchart showing an example of the carbon stripe positioning procedure. Therefore, next, the operation of the phosphor film forming apparatus shown in FIGS. 1 to 6 will be described in order of FIG.

First, the Z-axis 2 a of the orthogonal robot 2 is retracted to a position that does not interfere with setting the CRT panel 16 on the panel mounting base 11, and the Y-axis 2 b of the orthogonal robot 2 is set as a transfer start position. Then, the CRT panel 16 is set on the panel mounting base 11 in close contact with the heater 18 for heating the panel. In addition, the panel heating heater 18 is heated here, so that the entire CRT panel 16 is preheated (see FIG. 7A).

Next, the motor 8 is driven to rotate the ball screw 9 so that the panel mounting base 11 is located at a predetermined position, that is, the line requiring the transfer of the phosphor is substantially right below the transfer head unit section 5 in the center of the apparatus. To the position (step S1, see FIG. 7B). In the movement here, a raw image near the first line is obtained by the stripe recognition device 24 (step S2), the raw image is binarized by image processing, and the position of the carbon stripe is calculated from the number of pixels ( In step S3), this is converted into coordinate position data of the robot 2 (step S3).
4). Further, the position data calculated here is transmitted to the robot 2, and when the position of the CRT panel 16 is determined, the transfer of the phosphor on the transfer paper 35 is started (step S5).

When starting the transfer, first, the Z-axis 2a
And the transfer head unit 5 is moved to the transfer start position of the line.

Subsequently, the Y-axis 2b is caused to run in the direction along the carbon stripes, and the transfer paper transport device unit 25 is driven to start the transfer paper 35 (see FIG. 7C). At the same time, the non-contact heat source 42 in the transfer head unit 5 is also turned on. During this traveling, the high-speed fine movement actuator 41 is operated while confirming the stripe shape by the stripe recognition device 24 so that the laser light or infrared light emitted from the non-contact heat source 42 always comes to a predetermined position. . This allows
The phosphor layer 35e on the transfer paper 35 is transferred between the carbon stripes 51, 51 on the CRT panel 16 side. Then, when the panel mounting base 11 is moved to a predetermined position, the phosphor 50 for one line is transferred and formed.

FIG. 9 is a diagram schematically showing an enlarged portion A of FIG. 7C, and FIG. 10 is a side view of the portion shown in FIG. Then, the phosphor layer 35e on the transfer paper 35 is attached to the phosphor 5
When 0 is transferred to the CRT panel 16, the phosphor layer 35e is made to correspond to the carbon stripes 51, 51, and the transfer paper 35 is pressed by the pressure roller 41.
The transfer head unit 5 is moved via the robot 2 while being pressed against, and the transfer paper 35 is moved on the pressure roller 41 in synchronization with the movement of the carbon stripe 51. Then, the phosphor layer 35e on the transfer paper portion 35, which is warmed by the non-contact heat source 42 in the transfer paper guide member 38 and slightly melted and easily peeled off, is removed from the CRT.
It is peeled off and transferred to the panel 16 side.

When the phosphor 50 for one line is transferred, the Z axis 2 a of the orthogonal robot 2 is moved upward to separate the transfer head unit unit 5 from the CRT panel 16, and then the motor 8 is driven. By rotating the ball screw 9, the panel mounting base 11 is moved by one stroke pitch, and the phosphor 50 is transferred to the next line in the same manner. FIG. 11 is a partially enlarged view showing a state of the panel surface after the phosphors 50 are sequentially transferred onto the CRT panel 16 in this manner.

Therefore, in the fluorescent film forming apparatus of this embodiment, the following (1) to (7) which are not in the conventional fluorescent film forming apparatus are used.
There are advantages as described in.

(1) Since the CRT panel 16 is rocked in the direction orthogonal to the carbon stripes 51 by the rocking mechanism composed of the panel rocking roller 15 and the elongated guide holes 12, etc. By adjusting the swing locus to the curvature of the inside of the CRT panel 16, the pressure roller 41, the non-contact heat source 42, the transfer paper 35, and the transfer paper guide member 38 are kept inside the CRT panel 16 from a constant vertical direction. The phosphor 50 can be formed on the inner surface of the CRT panel 16 by being placed in contact with.

(2) Further, the pressure roller 41, the non-contact type heat source 42, the transfer paper 35, and the transfer paper guide member 38 can be always disposed in contact with the inside of the CRT panel 16 in a constant vertical direction. , At the time of transfer, each of these members is C
A structure for preventing physical interference with the outer peripheral portion of the RT panel 16 can be easily made.

(3) Transfer paper 35 to which phosphor 50 is attached
Is pressed immediately before transfer, and is heated and melted to transfer, so after transfer, necessary parts are not dropped,
Further, the phosphor 50 can be formed with a stable line width. Further, by pressing the transfer paper 35 to which the phosphor 50 is attached immediately before the transfer, it is possible to confirm the stripe position where the phosphor 50 is transferred and the position of the phosphor layer 35e until just before the transfer, and until just before the transfer. Transfer paper 35
Does not directly contact the CRT panel 16, so that erroneous transfer does not occur to an unnecessary portion.

(4) A panel heating heater 18 is provided on the panel mounting base 11, and the CRT panel 16 is set on the panel mounting base 11 by placing the CRT panel 16 in contact with the panel heating heater 18. With the CRT panel 16 preheated by the heater 18 for heating,
Since the thermal transfer from the transfer paper 35 is performed, it is possible to sufficiently secure the heat capacity required for transferring the transfer paper 35 to the CRT panel 16. As a result, high-speed transfer is possible and the working speed is improved. Also, stable quality can be obtained without controlling the temperature of the entire work place.

(5) By attaching the non-contact type heat source 42 of the transfer head unit 5 through the high speed fine movement actuator 41 such as a piezoelectric element, it is possible to transfer a curve to some extent and to simultaneously transfer a plurality of lines. Also, it is not necessary to mechanically limit the heat source interval. Further, by using this actuator, the portion used for transferring once can be offset and the untransferred portion can be effectively used.

(6) Since the non-contact type heat source 42 of the transfer head unit 5 is a non-contact type such as infrared light or laser light, a high output can be achieved with a spot diameter ratio and a medium having a large heat capacity. It becomes easy to transfer to. Also, the heat source 4
Good thermal response can be obtained by switching ON / OFF of 2, and there is no fear of damage due to abrasion of the transfer paper 35 or the head portion (pressure roller 43).

(7) Since the phosphor 50 can be formed on the CRT panel 16 side by a dry printing method called thermal transfer, a washing machine, a dryer, an exposure table and a frit coater as used in the wet method. A single-function device such as is unnecessary. Also, by devising stripes having a multi-layered structure on the transfer paper 35 side in advance, it is possible to collectively form them by one transfer, and since it is a single process, the process management man-hours can be reduced, and further dry printing can be performed. To use the method,
No need for purification equipment for liquid recovery and regeneration. Further, during transfer to the periphery of the effective screen, it becomes easy to prevent physical interference between the panel periphery and the pressure roller 41, the non-contact heat source 42, the transfer paper 35, the transfer paper guide member 38, and the like. .

In the above embodiment, the case where the phosphors 51 are transferred one by one has been described, but it is possible to transfer a plurality of phosphors 51 at the same time.

[0041]

As described above, according to the present invention,
It is possible to construct a dry type phosphor production system, simplify production facilities, etc., lower costs and make CRT cheaper.
Panels can be provided. Further, since the structure for swinging the CRT panel in the direction orthogonal to the carbon stripes is adopted by the panel swinging means, the swinging locus is adjusted to the internal curvature of the CRT panel to thereby transfer the transfer head. CR always means from a constant vertical direction
Since the phosphor can be formed by being placed in contact with the inside of the T panel and transferring the phosphor to the inner surface of the CRT panel, it is expected that the device can be simplified.
