The upper plate portion 210 has a substantially flat shape, and may be fixed by a plurality of legs 211, for example. For example, but not limited to, each of the four legs of the top plate 210 is provided with legs 211, and these legs 211 may be fixed to the ground. Of course, the lower surface of the top plate 210 may maintain an approximately or almost flat state.

The lift 180 may be installed under the top plate 210 in a size and / or area corresponding to the top plate 210. In one example, the lift 180 may include a substantially flat base 181 and a pneumatic or hydraulic cylinder 182 that elevates the base 181 in the vertical direction. In one example, the cylinder 182 is installed in each of the corners of the base 181, so that the base 181 may be raised or lowered. Of course, the polished metal plate 240 may be seated on the base 181 of the lift 180. Therefore, when the lift 180 is raised, the metal plate 240 approaches the upper plate portion 210.

The LM guide 190 is installed between the upper plate portion 210 and the lift 180 and can move in a substantially horizontal direction along the upper plate portion 210 and the lift 180.

The flatness sensor 120 is mounted on the LM guide 190 to sense / scan the flatness of the surface of the metal plate 240 on the lift 180 and transmit it to the control unit 150. In one example, the flatness sensor 120 is mounted on one side of the second horizontal LM guide 192, and thus moves in a horizontal direction together with the second horizontal LM guide 192. The flatness sensor 120 may be implemented as any one selected from, for example, but not limited to, a laser sensor, an ultrasonic sensor, a microwave sensor, an infrared sensor, an optical sensor, and the like.

The pressure rod 220 is mounted on the LM guide 190 so that when the lift 180 rises, the upper portion is supported on the upper plate portion 210 and the lower portion pressurizes the metal plate 240. In one example, the pressure rod 220 is mounted on the other side of the second horizontal LM guide 192, and moves in the horizontal direction together with the second horizontal LM guide 192.

Moreover, the thickness of the pressure rod 220 may be thicker than the thickness of the LM guide 190 (the first horizontal LM guide 191 and / or the second horizontal LM guide 192) and the flatness sensor 120.

In this way, the control unit 150 moves the LM guide 190 to a position where the flatness of the metal plate 240 obtained from the flatness sensor 120 is greater than a preset reference value, where the pressure rod 220 is to be calibrated. The horizontal position of the LM guide 190 and the vertical position of the lift 180 are controlled such that the flatness of the metal plate 240 is corrected within a reference value by raising the lift 180 and the pressure rod 220. .

Here, even if the upper end of the pressure rod 220 is supported by the upper plate portion 210 and the lower end of the pressure rod 220 may be in a state of pressing the metal plate 240, the LM guide 190 and the flatness sensor 120 ) Is not damaged. Moreover, by connecting the pressure rod 220 to the LM guide 190 through the elastic member 230, the upper end of the pressure rod 220 is supported by the upper plate portion 210 and the lower end of the pressure rod 220 is a metal plate 240 ) Even if it can be in a pressing state, the force applied to the pressure rod 220 is not directly transmitted to the LM guide 190.

4 is a flow chart illustrating a method for automatically flattening a polished metal plate according to an embodiment of the present invention. Here, reference will be made to FIGS. 1 to 3 together.

First, when the polished metal plate 240 is positioned on the lift 180 that can be lifted toward the fixed top plate portion 210, the control unit 150 uses the flatness sensor 120 while moving the LM guide 190. The flatness for each horizontal position of the metal plate 240 is sensed (S1).

Here, the control unit 150 moves the LM guide 190 in the first horizontal direction and / or the second horizontal direction, thereby sensing the flatness of all horizontal positions of the metal plate 240 by the flatness sensor 120. As possible.

As described above, when the flatness data for each horizontal position of the metal plate 240 is obtained, the control unit 150 compares it with a preset reference value to determine whether there is a position to be corrected and a correction value in the metal plate 240. . (S2)

For example, the control unit 150 determines whether calibration coordinates and calibration values for each calibration coordinate exist on horizontal X and Y coordinates.

Subsequently, the control unit 150 determines a position to be corrected and a correction value, and stores it in a memory. (S3) That is, the control unit 150 compares the flatness value for each horizontal position with a predetermined reference value, to a certain extent. Decide whether to calibrate with the dimensions of and save the calibration value.

Accordingly, the upper end of the pressure rod 220 is supported by the upper plate portion 210, and the lower end of the pressure rod 220 presses the metal plate 240. Accordingly, the flatness of the metal plate 240 is brought within a preset reference value.

Here, since the control unit 150 has already determined / calculated the correction value, the lift plate 180 is raised until the correction value is satisfied so that the metal plate 240 is pressed by the pressure rod 220.

After this operation, the control unit 150 returns the lift 180 to its original position. Here, the pressure rod 220 is coupled to the one side of the LM guide 190 through the elastic member 230, so that the LM guide 190 may not be deformed or damaged by the lift 180. . In addition, since the thickness of the pressure rod 220 is thicker than the thickness of the LM guide 190 and the thickness of the flatness sensor 120, the flatness sensor 120 will not be damaged by the lift 180. You can.

Subsequently, the control unit 150 senses the flatness for each horizontal position of the metal plate 240 using the flatness sensor 120 while moving the LM guide 190 again (S6).

As described above, when the flatness data for each horizontal position of the metal plate 240 is obtained, the control unit 150 compares it with a preset reference value to determine whether there is a position to be corrected and a correction value in the metal plate 240. . (S7)

If the calibration position and the calibration value exist, the control unit 150 returns to step S3 so that steps S3 to S7 described above are repeated. In addition, if the calibration position and the calibration value do not exist, the control unit 150 uses the output unit 170 to output data before and after calibration of the metal plate 240, that is, flatness data. (S8)
