Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate transfer device which can easily transfer substrates of different sizes when transferring substrates from one position to another.

[0002]

2. Description of the Related Art For example, when a substrate supplied from a magazine is transported in the transportation of substrates, conventionally, it has been carried out by a conveyor system as shown in FIG. 3 or a shuttle system in which a substrate is lifted and transported.

That is, in the conveyor type conveying apparatus shown in FIG. 3, a rotating shaft 21 is rotatably mounted via two bearings 22 between two conveying rails 20 arranged opposite to each other.
A pulley 23 is fixed to the rotary shaft 21, and the pulley 23
The belt 24 is stretched around the belt 24 and guided by a guide 25 arranged on one of the transport rails 20 on the belt 24 to guide the substrate 2
6 is mounted, a pulley 27 is provided at one end of the rotary shaft 21 projecting to the outside of one of the transport rails 20, and the pulley 27 is rotated by a belt 30 stretched between the pulley 29 of the motor 28. Via the rotary shaft 21 as a pulley 23,
The belt 24 is driven to convey the substrate 26 on the belt 24.

[0004]

At this time, when the substrates 26 having different sizes are transported, conventionally, when the substrates 26 are displaced during the transportation, the guides 25 of the substrates 26 are caught and cannot be transported.

In the conventional substrate transfer apparatus as described above, the work of adjusting the width of the guide 25 to the size of the substrate 26 by an operator occurs and the productivity is lowered.

Alternatively, if a device for adjusting the guide width using a motor and a feed screw is added, the mechanism becomes extremely complicated, which is disadvantageous in terms of cost.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a lightweight and simple substrate transfer device capable of quickly and accurately transferring a substrate or the like to a predetermined position.

[0008]

Means for Solving the Problems As a means for solving the above-mentioned problems, the present invention provides a conveyance rail for inclining a substrate to be conveyed and guiding a lower end surface and a back surface of the substrate, which is rotatable and fixed in a conveying direction. The feed claw support shaft that is slid back and forth by a certain amount, is brought into contact with the end surface of the substrate supplied on the transport rail by the rotation of the feed claw support shaft, and the substrate is moved by sliding the feed claw support shaft in the transport direction. The configuration is such that a feed claw for carrying a fixed amount is provided.

[0009]

With the above construction, the upper end side of the substrate is free from any restriction and substrates of any size can be transported.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

First, FIGS. 1 and 2 showing an embodiment of the present invention.
Will be explained. FIG. 1 is a side sectional view for explaining the function of one embodiment. Reference numeral 2 denotes a transfer rail for receiving the substrate 1, and the frame 8 has the inclination θ which is a feature of the present invention.
Supported by. The feed claw 3 is attached to a feed claw support shaft 4 so as to be rotatable by a feed claw vertical cylinder 5, and the feed claw support shaft 4 is attached to a frame 9 via a feed bearing 7 and the feed bearing 7 Is reciprocally slidable by a substrate feeding cylinder 6. With such a configuration, the feed claw 3 is rotated downward by the feed claw vertical cylinder 5, and the feed claw 3 comes into contact with the end surface of the substrate 1 whose lower end surface and back surface are guided by the inclined transport rail 2 and the substrate feed cylinder. The feed claw support shaft 4 is slid through the feed bearing 7 by means of 6, and the substrate 1 is moved to a target position by the feed claw 3 fixed to the feed claw support shaft 4.

At this time, even if the substrate 1 is displaced during transportation, the weight W of the substrate 1 causes the force of W · sin θ to act in the lower direction of the transportation rail 2 and the displacement is automatically corrected.

After carrying out a certain amount of conveyance in this way, the feed claw 3 is rotated upward by the feed claw vertical cylinder 5, and is kept away from the substrate 1 by the substrate feed cylinder 6 by the feed claw support shaft. Slide back 4 and move to the next substrate 1
To prepare for sending.

As can be seen from FIG. 1, the upper end surface and the front surface of the substrate 1 are not restricted by the feeding mechanism. That is, the size of the substrate 1 is not affected by the feeding mechanism, and the substrate 1 can be transported with an extremely simple structure.

FIG. 2 is a plan view for explaining the function of the second embodiment. The basic configuration of the substrate transfer device is the same as that shown in FIG. 1. By adopting this configuration, the substrate 1 can be transferred without being affected by the difference in size. By attaching the mark 10 having the contents described, the mark reader 11 sends the information of the substrate 1 to the work station, so that the product type can be switched instantaneously. A difference in the size of the substrates is affected by placing stockers 12 and 13 for feeding the substrates and storing the substrates 1 on both sides of the transport rail 2 while inclining and feeding the substrates 1 along the inclination of the transport rail 2. A work system that can handle a wide variety of products that does not receive the load will be possible.

Further, the work unit 1 which makes the substrate 1 to be conveyed to an intermediate portion of the conveyance rail 2 horizontal and performs some processing on the substrate 1
4 may be provided, and after completion of the work, the work can be performed by inclining it again and carrying it.

[0017]

Since the present invention is constructed as described above, the present invention is capable of quickly transporting a substrate with an extremely simple structure, and is suitable for multi-product work that is not affected by the size of the substrate. It will contribute and its industrial effect will be extremely large.
