DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for transporting a substrate for a rectangular electronic component such as a liquid crystal substrate, a color filter, and a mask glass.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 10, jig holding plates 4 and 5 having locking portions 3 protruding horizontally at lower ends on opposite sides of a jig mounting plate 2 mounted on the upper end of a column 1 which can be raised and lowered and moved horizontally, are opposed to each other. It is mounted so that the distance can be adjusted by moving horizontally.

On the other hand, as shown in FIG. 10, engaging projecting portions 7, 7 which engage with the engaging portions 3, 3 project outward from both sides of the upper end of a box-shaped holding box 6, and engage with the inner surface of the lower end. Joint projection 7,
The holding projections 8, 8 project in the direction orthogonal to 7 so as to hold the lower ends of the plurality of rectangular substrates 9, 9,.

Another conventional example will be described with reference to FIGS. 11 and 12. Referring to FIGS. 11 and 12, long and short holding plates 10, 11, and 1 are provided on both sides of a jig mounting plate 2 mounted on an upper end of a column 1 which moves up and down and moves horizontally.
The shafts 0 and 11 are pivotally mounted on the shafts 12 and 13 so as to be swingable. In addition, the long holding plates 10 and 10 are provided on the column 1 side, and the short holding plates 1
Position 1,11. Then, the short holding plates 11 on both sides,
The lower end of 11 is connected by a connecting plate 14 and a side support rod 15 for supporting the side surface of the substrate 9 formed of a round bar slightly above is fixed. Also, the lower ends of both length holding plates 10 and 10 are
And a substrate support rod 17, formed of a round bar,
17, 17 are fixed to three places, and the lower end and side surfaces of the rectangular substrate 9 are held in an inclined state as shown in FIG.

[0005]

In the case of using the conventional holding box, the transfer of a rectangular substrate is stable, but when immersion cleaning or the like such as wet processing is performed, the cleaning is performed. The amount of the liquid taken out of the tank is increased by the amount of the jig for transport such as a holding box, and the consumption of the liquid increases, which is uneconomical when expensive liquid is used.

In the case of another example, since the rectangular substrate is held by opening and closing each of the long and short holding plates by rotating the shaft, a transfer jig such as a holding box is not used. Even if immersion washing or the like such as processing is performed, the amount of liquid taken out is small and economical. However, since the rectangular substrate is held in an inclined state, there is a drawback that transport becomes unstable and the substrate is easily dropped. Further, in this conventional example, there is a disadvantage that the edges of the four sides of the substrate, such as a glass substrate, are easily broken and disappear.

In view of the above, an object of the present invention is to provide an apparatus capable of securely holding a rectangular substrate without using a transport jig.

[0008]

According to the present invention, in order to solve the above-mentioned problems, the distance between the side support rods holding both upper ends of the rectangular substrate can be adjusted horizontally by a jig mounting board which moves up and down and moves horizontally. The lower shaft is fixed to the lower surface of the jig mounting board. The lower shaft is fixed rotatably to the lower surface of the rectangular substrate. Thus, a rectangular electronic component substrate transfer device is configured to pass between the rectangular substrates and then rotate the lower surface support rod to support the lower surface of the rectangular substrate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to FIG. A jig mounting plate 2 is fixed to the upper end of a column 1 that can be raised and lowered and moved horizontally, and holding plates 18, 18, 19, and 19 are mounted on four corners of the jig mounting plate 2 in a direction perpendicular to the column 1, respectively. The two holding plates 1 are formed so as to be movable.
The interval between 8 and 19 can be adjusted.

The holding plates 18, 1 provided on the column 1 side
8 are connected by side support rods 20 formed of round rods, and the lower ends of opposite holding plates 19, 19 are connected by side support rods 21 formed of round rods, and the upper end of square substrate 9 is connected. Support the sides.

A rotary shaft 22 is rotatably mounted at the center of the lower surface of the jig mounting board 2, and a lower support rod 2 is mounted on the lower end of the rotary shaft 22.
3 is fixed horizontally to support the lower surface of the rectangular substrate 9 as shown in FIG.

According to the present invention, the rectangular substrate 9 has the lower surface supported by both lower surface receiving portions 24 provided in a storage container (not shown) as shown in FIG. Both sides are supported by the receiving portions 25, 25.

In this state, the column 1 is moved to lower the jig mounting plate 2. At this time, as shown in FIG.
The lower support rod 23 is positioned in a direction orthogonal to the side support rods 20 and 21 and passes between the rectangular substrates 9 and 9 and is positioned on the lower surface of the rectangular substrates 9 and 9. Then, the holding plates 1 on both sides
8, 18, 19, and 19 are horizontally moved to narrow the gap between the side support rods 20 and 21 to hold the side surface of the upper end of the rectangular substrate 9 as shown in FIG. Then, after rotating the rotation shaft 22 to make the lower surface support rods 23 parallel to the side support rods 20 and 21, the column 1 is slightly raised to hold the lower surface of the rectangular substrate 9 as shown in FIGS. .

Thereafter, as shown in FIG. 8, when the column 1 is lifted, the rectangular substrate 9 is supported by the side support rods 20, 21 and the lower support rod 23, and the lower support parts 24, 24 and the side support parts are supported. Depart from 25,25.

[0015]

As described above, the present invention has the above-mentioned structure, and only supports both sides and the lower surface of the rectangular substrate with the support rods, respectively. It is economical because the amount of discharged liquid is small and a large amount of expensive liquid is not used. In addition, the rectangular substrate can be held vertically by a simple mechanism, the transport is reliable, and there is no possibility that the four corners are broken.
