2. Description of the Related Art Generally, a PDP (plasma dis) is used.
play panel: Plasma display panel), PALC (plasma addressed)
2. Description of the Related Art A barrier rib-like material forming apparatus is used to form a barrier rib-like material on a substrate used for an FPD (flat panel display) such as a liquid crystal display (LCD). 2. Description of the Related Art Conventionally, a device for forming a barrier rib-like material disclosed in, for example, Japanese Patent Laid-Open No. 2000-243267 is known. As shown in FIG.
And is provided above the base 52 in the horizontal direction (AB direction)
The moving head 53 is provided with a moving head 53, an air cylinder 57 provided on the moving head 53, a blade holder 54 supported by the air cylinder 57, and a blade 55 held by the blade holder 54.

The base 52 has its upper surface formed horizontally, and the substrate 70 is arranged on this upper surface. The surface of the substrate 70 is coated with a ceramic paste in a film shape. In this state, the ceramic paste becomes a paste film 71. This ceramic paste is obtained by kneading glass powder or glass-ceramic mixed powder with resin and solvent.

The moving head 53 is a support column 52a of the base 52.
It is supported by a pair of male screw shafts 56 that are rotatably attached to, and moves in the AB direction when the male screw shafts 56 rotate. The moving head 53 is provided with a pair of left and right air cylinders 57. The blade holder 5 is attached to the lower end of the rod 57a of the air cylinder 57.
4 are supported.

The blade holder 54 is used for the air cylinder 5
7, the air tank 58 and the air pressure adjusting device 59 enable movement in the vertical direction (CD direction). A slit 54a for holding the blade 55 is provided below the blade holder 54 to move the moving head 53. It is formed in a direction (EF direction) orthogonal to the direction.

The blade 55 is made of metal, ceramic, resin or the like in a plate shape, and has a plurality of comb teeth 55a at its lower end. Further, the blade 55 is held by the blade holder 54 by inserting the upper end portion thereof into the slit 54a of the blade holder 54, and the lower end portion thereof is held by the base 5
2 and the surface of the substrate 70 are arranged to be horizontal.

As shown in FIG. 6, when the comb tooth 55a is pierced into the paste film 71 and moved in the B direction, the portion of the paste film 71 that contacts the comb tooth 55a is swept away by the comb tooth 55a, or , Moves to the gap between the comb teeth 55a and passes through this gap. The paste film 71 that moves into the gap between the comb teeth 55a forms a barrier rib-like object 72 together with the paste film 71 that is located in the gap between the comb teeth 55a. In addition, the paste 73 swept from the paste film 71 by the comb teeth 55a is attached / accumulated on the blade 55.

[0008]

However, in the above-mentioned barrier rib-like material forming apparatus 51, the paste 7 is used.
3 accumulates on the blade 55, so as shown in FIG.
At the terminal end portion 70a of the substrate 70, when the blade 55 is separated from the substrate 70 and the barrier rib-like material 72, the paste 73 accumulated on the blade 55 drips on the surface of the substrate 70 and is formed at the terminal end portion 70a. There is a problem that the shape of the barrier rib-shaped material 72 is disturbed. In addition, the blades 55 are formed on the substrate 7 before the barrier ribs 72 are formed without removing the paste 73 accumulated on the blades 55.
When piercing 0, there was a problem that the shape of the barrier rib-like material 72 formed in the pierced portion was disturbed.

Further, when the barrier ribs 72 are continuously formed on a large number of substrates 70 using the blade 55, the paste 73 accumulated on the blade 55 increases and the paste moves to the gaps of the comb teeth 55a. Since the amount of the film 71 changes, there is a problem that the height of the barrier rib-like material 72 formed changes as the number of substrates 70 increases. Therefore, in the past, as a method of forming the barrier rib-shaped material, the paste 73 accumulated on the blade 55 was removed every time the barrier rib-shaped material 72 was formed on several substrates 70. Since the work of removing the paste 73 is interrupted, the production efficiency is low.
