Description

Technical Field

[0001] The present invention relates to the technical field of strip rolling thickness control and measurement, and particularly to a thickness measuring instrument for thin strip asynchronous rolling and its process. Background Art

[0002] During the thin strip asynchronous rolling process, accurately measuring the thickness is crucial for ensuring product quality. Precise thickness control enables the product to meet the specification requirements, improving product performance and reliability. For example, in fields such as electronics and aerospace where extremely high material accuracy is required, even a tiny deviation in the thin strip thickness can affect the performance of the final product. At the same time, accurate thickness measurement helps to optimize the rolling process. By real-time monitoring the thickness data, rolling parameters such as roll gap and differential speed ratio can be adjusted in a timely manner, improving production efficiency, reducing production costs, and decreasing the reject rate.

[0003] When the existing thickness measuring instrument for thin strip asynchronous rolling is in use, it mainly measures the thickness of the thin strip by using a laser displacement sensor or an ultrasonic sensor, so as to achieve the purpose of controlling the thickness of the processed thin strip and adjusting the parameters of the processing equipment as required.

[0004] However, the existing thickness measuring instrument for thin strip asynchronous rolling and its process have the following deficiencies: Most of the existing thickness measuring instruments for thin strip asynchronous rolling measure the thickness of the thin strip by using a single-sensor measurement method. The measured area and range are limited, and it is impossible to ensure the unity of the thickness values of the entire thin strip. Moreover, the measurement position cannot be adjusted flexibly, resulting in poor measurement accuracy, which is likely to affect production efficiency and increase the yield of defective products, and it is difficult to meet the actual use requirements.

[0005] Therefore, we propose a thickness measuring instrument for thin strip asynchronous rolling and its process to solve the problems raised above. Summary of the Invention

[0035] According toFigure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown in Figure 8 and Figure 9 , the dust removal mechanism 9 includes a dust removal box 901. The dust removal box 901 is arranged on the top of the third U-shaped frame 701. A filter plate 902 is inserted into the interior of the dust removal box 901. An axial flow fan 903 is also installed inside the dust removal box 901. A dust-proof cover 904 is installed at one end of the dust removal box 901.

By arranging the dust removal mechanism 9, it is possible to adsorb the dust and impurities on the surface of the thin strip, filter and collect the adsorbed dust and impurities, thereby facilitating subsequent processing, saving labor and time costs, and further improving the measurement accuracy.

[0036] Working principle: First, place the main body mechanism 1 of the measuring instrument at the designated position for thin strip measurement, drill holes according to the installation requirements. After the drilling is completed, turn the fastening bolt 11 to cooperate with the anti-slip gasket 12 to install and fix the main body mechanism 1 of the measuring instrument at the designated position to ensure the stability of the measuring instrument during use. Then, connect an external power supply device to the internal electrical equipment of the measuring instrument to provide functions for it and ensure its normal operation. Then, form a closed information interaction and collaborative operation between the servo equipment, laser displacement sensor 3 and ultrasonic sensor 5 inside the measuring instrument and the external control system to achieve an efficient control scheme.

[0037] During the dust removal stage, place the thin strip to be measured on the top of the measurement platform 101 and push it forward with the help of external equipment. The axial flow fan 903 adsorbs the dust and impurities existing on the surface of the thin strip, so that the dust and impurities enter the dust removal box 901 through the dust collection hood 908 and the connecting pipe 907. The filter plate 902 blocks and filters the dust and impurities. The blocked and filtered dust and impurities fall into the collection box 906 for collection, facilitating subsequent processing.

[0038] During the cleaning stage, the external control device controls the servo cylinder 803 to start. The servo cylinder 803 pushes the cleaning roller 704, causing the mounting block 702 to slide in the chute 801, so that the cleaning roller 704 fits on the top surface of the thin strip to be measured. The external control system controls the third servo motor 703 to start. The third servo motor 703 drives the cleaning roller 704 to rotate to clean the dirt on the top surface of the thin strip, preventing the accumulation of dirt from affecting the measurement accuracy and thus improving the measurement quality.

[0039] Adjustment and calibration stage: When the thin strip reaches the area to be inspected where the laser displacement sensor 3 and the ultrasonic sensor 5 are located under the push of an external device, the first servo motor 203 is controlled to start by an external control device. The first servo motor 203 drives the first bidirectional lead screw 204 to rotate, prompting the first sliding frame 205 to drive the metal upright frame 206 to slide on the first bidirectional lead screw 204 and the metal guide rod 202 to calibrate the thin strip and prevent it from shifting. Meanwhile, during the sliding process, the connecting frame 13 drives the sliding block 403 to slide on the guide rod 402, prompting the first link frame 404 to rotate and pushing the mounting frame 405 downward, so that the detection end of the ultrasonic sensor 5 fits against the top surface of the thin strip.

[0040] Fine adjustment and detection stage: The second servo motor 601 is controlled to start by an external control device. The second servo motor 601 drives the second bidirectional lead screw 602 to rotate, prompting the two second sliding frames 603 to slide on the second bidirectional lead screw 602, causing the second link frame 604 to rotate and pushing the connecting seat 605 and the second U-shaped frame 606 to displace, thereby independently adjusting the laser displacement sensor 3. Meanwhile, the thin strip to be detected is further calibrated to enable the laser displacement sensor 3 to reach the accurate detection position. Then, the laser displacement sensor 3 and the ultrasonic sensor 5 are controlled to start by an external control device. The ultrasonic sensor 5 measures the middle thickness of the thin strip, and the laser displacement sensor 3 measures the thicknesses at both ends of the thin strip. By organizing and comparing the measurement data of the two, it can be confirmed whether the overall thickness of the thin strip is consistent.

[0041] Operating according to the above description can complete the use of the asynchronous rolling thickness measuring instrument for thin strips.
