A plurality of (two in the illustrated example) are provided so as to contact and position the other side flb adjacent to the one side 118 of No. 1. For these first fixed rollers 12 and second fixed rollers 13, each side 11 that they contact is
! , each other side 11c facing the llb, a first roller-shaped clamp body (hereinafter referred to as the first clamp roller) +4 and a second roller-shaped clamp body (hereinafter referred to as the second clamp roller) to abut on the lid. ) 15 are provided. These clamp rollers 14. On the 15th,
A clamping force directed toward each of the other sides 11c and Ild (in the direction of the arrow in the drawing) with which they come into contact is applied by a spring (not shown).

Each of the clamp rollers 14, 15 contacts the corresponding sides 11c and l1dd of the substrate 11, and uses their clamping force to press the substrate 11 against the first fixed roller 12 and second fixed roller 13, holding it in a fixed position with good reproducibility. Position.

By the way, there is also a demand for such a substrate 11 to be used in many different types. In order to meet this demand, it is necessary for the positioning device to keep the center position of the substrate within a certain range even if the size of the substrate differs due to the transportation system and other tools.

FIG. 2 shows the positioning state of the substrate 11 (two types, large and small, are shown) indicated by a chain double-dashed line. Explained by J.

First, as shown in FIG.
Select from 9.20.

A method for selecting fixing positions suitable for the substrate size from the plurality of screw holes 19 and 20 will be described below.

First, the positions of the screw holes 19 in the Y direction are determined from the outside as x, n, m, . . . according to FIG. Also, the position of the 20th screw hole in the X direction is 1.2 from the outside for each row A, B, and C.
3. That is, from the outside, row A is A, A2,
Define A. Column B and column 0 are determined in the same manner.

FIG. 5 shows the relationship between the dimensions of the substrate 11 in the X1Y directions and the positions of the screw holes 19 and 20 in the X1Y directions.

That is, the size of the substrate 11 to be positioned is X=
60 and Y=70, the position of the screw hole of the first fixed roller 12 from FIG. 5 is the position marked with ■ in FIG. 3. Also, the second fixed roller 13! The screw hole position is located at B2 in FIG.

After fixing the first fixed roller 12 and the second fixed roller 131 in this way, the substrate 11 is moved to the substrate stage 3.
8.

Next, as shown in FIG. 7(b), another second fixed roller 13b is attached. This second fixed roller 13
b is attached at a position in the Y direction that can contact the other side 11b of the substrate II and is farthest from the second fixed roller 13g. Further, in the X direction, the position is the same as that of the second fixed roller H1.

Next, as shown in FIG. 7(C), the first clamp roller 14 is attached to the corresponding screw hole 28 of the slider 2G. This mounting position is such that the distance from the first fixed roller 12 is shorter than the length of the substrate 11 in the Y direction, and
This is the position farthest from the fixed roller 12. To set the first clamp roller 14 in the screw hole 28 at this position, the slider 26 is moved against the tension of the spring 31, and the screw hole 28 to be mounted is aligned with the side 11 of the substrate 11.
c, and the second clamp roller I4 is screwed into this screw hole 28 with a screw 30.

After attaching the first clamp roller 14 in this way, the force on the slider 26 is released, and the clamping force of the spring 31 moves the first clamp roller 14 to the side 1 of the substrate 11.
1c and clamped in the Y direction with the first fixed roller 12.

Next, as shown in FIG. 7(d), the second clamp roller 15 is attached to the corresponding screw hole 29 of the slider 27. This mounting position is selected in the same manner as the first clamp roller 14. That is, the distance from the second fixed roller 13 is shorter than the length of the substrate If in the X direction, and the screw hole 2 is located at the farthest position from the second fixed roller 13.
Select 9. When setting the second clamp roller 15 in this selected screw hole 29, the slider 27
The screw hole 29 to be mounted is pulled out from the side lid of the substrate 11, and the second clamp roller 15 is screwed into this screw hole 29 with the screw 30. Stop it.

Thereafter, the force on the slider 27 is released, the second clamp roller 14 is brought into pressure contact with the side 11c of the substrate 11 by the clamping force of the spring 32, and the second fixed roller 13 is clamped in the X direction.

As a result of the above clamping operation, the side 111 of the substrate If.

11b is a corresponding fixed roller 12 as shown in FIG.
, pressed against 13. Fixed roller 12. Since the shank of 13 engages with the corresponding one of the stopper steps 21, 22 as described above, this stopper step 21, 22
If it is precisely processed, position repeatability, including parallelism between substrates of different substrate sizes, can be maintained with high accuracy. Further, even when a plurality of such substrate positioning tables 42 are provided and substrates are processed and processed alternately, almost no error occurs between the plurality of tables 42.

That is, position repeatability can be maintained with high precision.

In this way, the first fixed roller 12 and the second fixed roller 13 are adjusted according to the size of the substrate 11 to be positioned.
, and the set positions of the first clamp roller 14 and the second clamp roller 15 are also determined accordingly, so substrates If of various sizes can be reproduced within a range where the center position does not shift significantly. It allows for easy and highly accurate positioning.

In the second example, by positioning the substrates of mouths 30 to 100 (targeted as vertically long rectangles, but also suitable for horizontally long rectangles with a small aspect ratio) using the method described above, the shift in the center position is prevented. I was able to position everything within a φ14 door.

FIG. 8 shows the board positioning table 42 explained in FIG.
shows an example of its use. In this example, two substrate positioning tables 42 are mounted on opposite sides of a table stage 43. These two board positioning tables 4
The stage switching mechanism 51 switches the position of No. 2 between the front and the back in the figure with high precision. Then, the front side is the loading and unloading position of the board 11,
It is assumed that the substrates 11 transported from a pre-processing position (not shown) are sequentially processed with the back as a processing position, and then transported to a post-processing process (not shown).

When used in this manner, the positioning accuracy (reproducibility) of each size at the processing position by the two substrate positioning tables 42 is maintained high, and good processing can be performed.

The opening and closing operations of the first clamp roller 14 and the second clamp roller 15, that is, the movement of the sliders 26 and 27, are driven by a power opening and closing mechanism consisting of, for example, the cam 52 and its drive mechanism 53 shown in FIG. It's okay.

As described above, according to the present invention, it is possible to position boards of various sizes with high precision and reproducibility while keeping the deviation of the center position within a certain range, and unlike conventional methods, a dedicated positioning device for each size is provided. There is no need to do so, and it is possible to simplify the entire equipment and reduce costs.
