For example, if the Y-axis position of the cutter wheel 111 and the movement of the cutter wheel unit 110 to the reference position are determined manually, the use of the image module 200 and the control module 300 can be omitted.

The pair of cutting cutter wheels of the cutting device of the present invention will be described in detail below. Quasi-acting.

First, the operator measures the initial position of the cutting wheel 111 of each cutting module 100.

To achieve the above objective, the image module 200 captures an image of the position of the cutting wheel 111 and conveys the image data to the control module 300.

The control unit 300 receives the image position of the initial position of the image module 200, compares the image data with preset reference position data, and calculates that the cutting wheel 111 is to move in the X-axis, the Y-axis, and the Z-axis direction. The displacement.

If necessary, the monitoring device outputs image data of the initial position of the cutting wheel 111, reference position data, and calculated displacement.

In particular, the cutter wheel adjusting member 520 of the Y-axis moving device 500 moves the sliding member 510 based on the required displacement of the cutting wheel 111 on the Y-axis, thereby aligning the cutting wheel with the cutting wheel 111 corresponding to the Y-axis direction. .

When the operator manually operates the cutter wheel adjusting member 520, the operator can operate by viewing the detecting device or using a numerical value corresponding to the calculated Y-axis displacement, and is separately set. The distance sensor is derived from data.

On the other hand, the cutter wheel adjusting member 520 is automatically controlled in this case, and the control unit 300 controls the motor by calculating the required Y-axis displacement, so that the electric energy of the motor is transmitted to the cutter wheel adjusting member 520 through the power transmission element. To adjust the alignment position of the cutter wheel 111.

The control module 300 also controls the Z-axis motor 160 of the cutting module 100 according to the preset Z-axis reference position, so that the cutting head 120 is in the Z-axis direction. Move up to adjust the alignment position of the cutter wheel 111.

Furthermore, the control module 300 moves the cutting module 100 along the guiding rod 600 in the X-axis direction according to the data of the image captured by the image module 200 and the data of the X-axis reference position to adjust the cutting wheel 111. Aligned position.

The order in which the cutter wheel 111 is aligned in the X-axis, Y-axis, and Z-axis directions is not limitative.

Thus, when the cutting wheel 111 arranged on the guiding rod 600 is accurately adjusted to the alignment position, the control module 300 sends a signal to the cutting device 1000 to form the cutting wheel 111 on the glass substrate 15. A cutting line SL.

As described above, after the cutting device 1000 of the present invention reads the exact position data of the cutting wheel 111 by the image module 200, the alignment operation of the cutting wheel 111 is only required to be based on the read position data. The cutter wheel unit 110 moves in the Y-axis direction with respect to the cutting head 120. Therefore, the cutting device of the present invention can prevent deformation or sagging of the device due to its own weight and moment, thereby ensuring the precision of the cutting process.
