本発明は塗布装置特にエアガンを用いて塗布を行う装置
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coating device, and particularly to a device for coating using an air gun.
従来、プラズマディスプレイに用いるガラス基板に、耐
放電性物質を含む溶液を塗布する場合は、第２図に示す
塗布装置が用いられていに。Conventionally, when applying a solution containing a discharge-resistant substance to a glass substrate used in a plasma display, a coating apparatus shown in FIG. 2 has been used.
第２図に２いて、４Ｎ塗布物として複数枚のガラス基板
１０が装置された吹付は枠１１は、取付は棒１２を介し
て被塗布物移動装置１３に取付けられる。As shown in FIG. 2, a spraying frame 11 on which a plurality of glass substrates 10 are mounted as 4N coating materials is attached to a coating object moving device 13 via a rod 12.
被塗布物移動装置１３は、チェンコンベアやこれを回転

１を規定速度で横方向へ回転移動できる構造になってい
る。The object moving device 13 includes a chain conveyor, a motor for rotating the conveyor, etc.
1 can be rotated laterally at a specified speed.

ている。The particles of the sprayed coating liquid are sprayed through the opening s18 of the frame 11.
It adheres to a defined area of the glass substrate 10 exposed to the surface. : During spraying, the frame 11 is rotated horizontally at a specified speed by a chain conveyor, but since the air gun 14 is also configured to move up and down, the glass substrate 10 attached to the frame 11 is sprayed. The coating liquid is sprayed evenly.

ガラス基板に付着する耐放電性物質が均一にならない。However, when the application liquid is sucked up using compressed air,
The load is not constant depending on the condition of the nozzle and the mixed state of the anti-discharge material mixed in the coating liquid, and the fluctuation of the hose 17 due to the vertical movement of the air gun 14, and the impact on particles of the sprayed coating liquid. Due to the influence of gravitational acceleration, etc.
The discharge-resistant material that adheres to the glass substrate is not uniform.

よりこの問題を解決した。The influence of the vibration of the hose 17 due to the vertical movement of the air gun 14 and the gravitational acceleration of the sprayed particles can be suppressed by slowing down the movement of the air gun 14, but it is not possible to maintain a constant amount of the applied liquid sucked up. I'm away. In the present invention, this problem is solved by continuously delivering a fixed amount of coating liquid to the air gun.

The applicator is connected to an object moving device that moves the object to be coated, and includes a bellows tank, a bellows tank drive unit that can increase or decrease the volume of the bellows tank, and a bellows tank drive unit that can increase or decrease the volume of the bellows tank. The inlet and outlet of the coating liquid connected to the bellows tank are opened alternately.
A solution metering discharge device comprising an opening/closing means for closing is provided between the tank and the air gun.
次に本発明の実施例を図面を用いて説明する。 Next, embodiments of the present invention will be described using the drawings.

。In FIG. 1, a bath liquid metering dispensing device 1 is connected to a bellows tank 2 made of a stainless steel plate, a bellows tank drive unit 3 that increases or decreases the volume of the piperose tank 2, such as an air cylinder, and the bellows tank 2. The valve 4ae5ak has an inlet 4 and an outlet 5 for the coating liquid, and is comprised of first and second air cylinders 6.7 which open and close alternately.

布液の量は一定となる。The first and second air cylinders 6.7 are connected to a bellows tank drive unit 3 that moves the bottom plate 2a of the bellows tank 2 up and down.
It is designed to move in conjunction with the vertical movement of the arm 3a. That is, when the arm 3a moves upward to reduce the volume of the bellows tank 2, the second air cylinder 7 opens the valve 5a of the outflow port 5, and at the same time closes the valve 4al of the inflow port 4. By this operation, the coating liquid in the bellows tank 2 is supplied to the air gun 14 connected to the outlet 5. Arm 3
When the speed of pushing up the bottom plate 2ak of a is constant, the amount of coating liquid supplied to the air gun 14, that is, the amount of coating liquid sprayed is constant.

尚、塗布時のエアガンの−Ｆ下動は、ホースの振れが塗
布液量の増減に影響しない程度に遅くする必要がおる。As described above, according to the embodiment of the present invention, since the solution quantitative discharge device is provided between the air gun 14 and the tank 17, the coating liquid sprayed from the air gun 14 is a constant amount and uniformly adheres to the object to be coated. . Therefore, when this coating device is applied to coating the discharge-resistant material of the FIT+F plasma display,
The anti-discharge material is applied uniformly and has less variation in properties, improving manufacturing yield and reliability. □ The -F downward movement of the air gun during coating must be slowed down to such an extent that the swinging of the hose does not affect the increase or decrease in the amount of coating liquid.

動させるようにしてもよい。In reality, it is sufficient to slowly move the air gun only upward or downward until the coating on the object is completed, that is, from the start to the end of coating. Alternatively, the air gun may be fixed and moved up and down while completely rotating the object to be coated.
また、上記実施例においては、塗布液の流入口と流出口
