[0019] A lifting platform 7 is provided on the left side of the top surface of the water platform 3, and a motor 1 is provided on the right side of the lifting platform 7; a lifting structure platform 5 is provided on the lifting platform 7; a high-precision grating ruler reading head 10 is provided on the rear right side of the lifting structure platform 5; a clamp 13 is provided in the middle of the top surface of the lifting structure platform 5; a color standard plate 6 is held in the clamp 13.

[0020] A support column 14 is provided on the rear left side of the top surface of the water platform 3. A rigid structure 9 is provided on the top of the support column 14 to form an inverted L-shaped support rod. A laser displacement sensor 8 is provided on the rigid structure 9. A display 11 is provided on the right side of the laser displacement sensor 8. A grating ruler 2 is provided on the rear right side of the top surface of the water platform 3.

[0021] Furthermore, the clamp 13 includes four inverted L-shaped clamping plates 131, which are arranged around the center of the top surface of the lifting structure platform 5 and are square in shape.

[0022] Furthermore, four spiral feet 4 are respectively provided at the four corners of the bottom surface of the water platform 3.

[0023] Furthermore, two horizontal bubbles 12 are provided on the front and rear sides of the left end of the surface of the lifting structure platform 5.

[0024] The working principle of this invention is as follows:

[0025] In this design, a high-precision grating ruler reading head 10 is installed on the rear right side of the lifting structure platform 5. A clamp is installed in the middle of the top surface of the lifting structure platform 5, holding a color standard plate 6. A support column is installed on the rear left side of the top surface of the water platform 3, and a rigid structure 9 is installed on the top of the support column. A laser displacement sensor 8 is installed on the rigid structure 9, and a display 11 for the laser displacement sensor is installed on the right side of the laser displacement sensor 8. A grating ruler 2 is installed on the rear right side of the top surface of the water platform 3. Specifically, the laser displacement sensor 8 is positioned above the color standard plate 6, and the high-precision grating ruler reading head 10 corresponds to the grating ruler 2.

[0026] In use, the bottom of the water platform 3 is equipped with four spiral feet 4 at the four corners. The four spiral feet 4 are used to adjust the level of the lifting structure platform 5. The two level bubbles 12 on the lifting structure platform 5 are used to adjust the level of the lifting structure platform 5.

[0027] Then, the lifting platform 7, which is an X-shaped lifter, is controlled by a motor to raise and lower. This drives the lifting structure platform 5 on the lifting platform 7, thereby raising and lowering the color standard plate 6 and the high-precision grating ruler reading head 10. By changing different color standard plates 6, the gloss of the laser displacement sensor 8 is tested. The grating ruler 2 is used to measure the value of the high-precision grating ruler reading head 10. Finally, the linearity of the sensor is tested by comparing the measured value on the laser displacement sensor display with the standard value of the grating ruler, thus completing the test.

[0028] This design is based on the detection method of an online monitoring device for the flatness of ceramic tiles, and is used to calibrate the laser displacement sensor of the monitoring device. Before measurement, the device is leveled by adjusting the leveling bubble of the lifting structure platform 5, and the gloss of the sensor is tested by changing the standard tile (color standard plate 6). During the test, the linearity of the sensor is tested by comparing the value displayed on the laser displacement sensor display with the standard value of the grating ruler through the motor lifting.

[0029] The advantages of this design are: it comprehensively assesses reliability by using sensitivity test results of the surface crystal and color characteristics of ceramic tiles, and it is convenient and accurate to measure.

[0030] In this design, the allowable tolerance of the online monitoring device for ceramic tile flatness is ±0.05mm, and the measurement error of the laser displacement sensor is less than 0.05mm, which meets the requirements.
