Description

Technical Field

[0001] The present invention belongs to the technical field of flatness measurement, and particularly relates to a device for measuring the flatness of stainless steel plates. Background Art

[0002] The flatness measurement of stainless steel plates is an important step to ensure their flatness, thickness uniformity and surface quality, and is widely used in fields such as steel manufacturing, automobiles, aerospace, and construction. For example, a device for measuring the flatness of steel plates proposed in the patent publication number CN221173237U.

[0003] During the production process of stainless steel plates, conditions such as wear on the surface of the rolling rolls and poor machining accuracy will cause the local roughness of the steel plates to increase. When using a laser positioning sensor to measure the flatness of stainless steel plates, the rough surface will complicate the reflection path of the laser beam. Some lasers may reach the sensor after multiple reflections in the surface depressions before being received; some lasers will be reflected in advance due to surface protrusions. This series of abnormal reflection situations will cause the laser propagation distance calculated by the sensor to deviate from the actual value, and ultimately seriously interfere with the accurate determination of the surface position of the stainless steel;

[0004] In addition, during the rolling of stainless steel plates, rolling oil is usually used to assist in processing. When measuring stainless steel plates, the rolling oil is not completely removed. The remaining oil stains, due to their certain light absorption and light transmission properties, will have an adverse effect on the laser. When the laser irradiates the stainless steel surface with oil stains, some lasers will be absorbed by the oil stains, and the other part will undergo refraction and scattering phenomena within the oil stain layer, resulting in a significant reduction in the light intensity reflected back to the sensor, seriously affecting the accurate measurement of the stainless steel surface position, and ultimately leading to a reduction in positioning accuracy.

[0005] Therefore, a device for measuring the flatness of stainless steel plates is proposed to solve the above problems. Summary of the Invention

A light signal generator 43 is fixedly connected to the right side wall of the moving plate 8, which can locate the position of the rough part.

[0037] The operating principle of the present invention is described as follows: Place the stainless steel plate to be measured on the surface of the placement plate 5. Then, the operator sends a control signal to the control cabinet 3. The control cabinet 3 first controls the second electric push rods 122 on both the left and right sides to work. The second electric push rods 122 drive the clamping seats 13 to move towards the stainless steel plate through pressure sensors (not shown in the figure). When the clamping seats 13 come into contact with the stainless steel plate, after the control cabinet 3 detects a pressure change through the pressure sensors fixed to the moving ends of the second electric push rods 122, the control cabinet 3 will control the second electric push rods 122 to stop working and control the small lead screw linear module 15 to work. The small lead screw linear module 15 will drive the ultrasonic probe 16 to move, and the ultrasonic probe 16 is used to detect the cut of the stainless steel plate, and tiny defects such as cracks, pores, inclusions, etc. can be detected, which helps to timely discover potential quality problems;

[0038] After the second electric push rods 122 stop moving, the control cabinet 3 will control the first lead screw linear module 4 to work. The first lead screw linear module 4 will drive the placement plate 5 and the stainless steel plate to move to the left together. While the first lead screw linear module 4 is working, the control cabinet 3 will also control the vision sensor 272 to detect the oil stain on the surface of the stainless steel plate. When the oil stain on the surface of the stainless steel plate is detected, the vision sensor 272 will transmit the data of the location of the oil stain to the control cabinet 3. The control cabinet 3 will control the fourth lead screw linear module 29 to work. The fourth lead screw linear module 29 drives the fixing plate 30 and the two fixing frames 31 to move to the advancing path of the oil stain together. Then, the control cabinet 3 controls the cleaning electric push rod 28 to work. The cleaning electric push rod 28 drives the pressing roller 35 to move downward, and the cleaning cloth under the pressing roller 35 contacts the surface of the stainless steel plate. When the oil stain passes under the pressing roller 35, the cleaning cloth under the pressing roller 35 can be used to clean the oil stain. After the oil stain is cleaned, the control cabinet 3 will control components such as the cleaning cloth roller 32 to move upward to the initial position together. At the same time, the control cabinet 3 will also control the winding motor 34 to work for two seconds. The winding motor 34 drives the winding roller 33 to slowly rotate, so that the contaminated area of the cleaning cloth under the pressing roller 35 is removed, and the other areas of the cleaning cloth are moved under the pressing roller 35 again;

[0039] After the stainless steel plate moves to directly below the laser positioning sensor 9, the shape of the stainless steel plate can be detected by the laser positioning sensor 9 (a position switch is provided on the inner wall of the connecting frame 2, which can detect the position of the stainless steel plate through the position switch and control the operation of the laser positioning sensor 9 through the control cabinet 3). And the detection result is transmitted to the display screen on the surface of the control cabinet 3. During the operation of the laser positioning sensor 9, the control cabinet 3 will also control the second lead screw linear module 6 to reciprocate. The second lead screw linear module 6 will drive the laser positioning sensor 9 to reciprocate, which can increase the detection area of the laser positioning sensor 9. When there is a rough area on the surface of the stainless steel plate, the rough surface will complicate the reflection path of the laser beam, causing the laser propagation distance calculated by the laser positioning sensor 9 to deviate from the actual value. The laser positioning sensor 9 will transmit an electrical signal to the control cabinet 3, and the control cabinet 3 will immediately control the first lead screw linear module 4 to drive the placement plate 5 and the stainless steel plate to stop working. Then the control cabinet 3 controls the first electric push rod 10 behind the laser positioning sensor 9 to work. The first electric push rod 10 will drive the probe detection mechanism 11 to move downward and contact the surface of the stainless steel plate. In combination, the control cabinet 3 controls the air pump 171 to work and controls the corresponding control valve 20 corresponding to the laser positioning sensor 9 to open. The air pump 171 will transport external gas to the corresponding pneumatic cavity 18 through the horizontal pipe 19, increasing the air pressure on the right side of the piston plate 21 in the pneumatic cavity 18. Under the action of the air pressure, the piston plate 21 will drive the moving plate 8 on this side through the bent rod 22, causing the moving plate 8 to drive the probe detection mechanism 11 to slide across the surface of the stainless steel plate, and use the probe detection mechanism 11 to detect the rough area of the stainless steel plate. When the probe detection mechanism 11 detects that the surface of the stainless steel plate is rough, the control cabinet 3 will control the optical signal generator 43 on the right side of the moving plate 8 to work. Then the control cabinet 3 controls the third lead screw linear module 232 to work. The third lead screw linear module 232 drives the horizontal electric push rod 24, the bent plate 25, the optical signal receiver 42 and the polishing machine 26 to move forward together (the horizontal electric push rod 24 is initially placed at a position near the rear side in the connecting frame 2). When the optical signal receiver 42 receives the optical signal emitted by the optical signal generator 43, the optical signal receiver 42 will transmit an electrical signal to the control cabinet 3, and the control cabinet 3 will control the third lead screw linear module 232 to stop working. Then the control cabinet 3 controls the third electric push rod 231 to work. The third electric push rod 231 drives the polishing machine 26 to move downward and contact the surface of the stainless steel plate. After the control cabinet 3 detects through the pressure sensor between the third electric push rod 231 and the third lead screw linear module 232 that the extrusion force between the polishing machine 26 and the stainless steel plate reaches the set threshold value (10N), the control cabinet 3 will control the third electric push rod 231 to stop working. Then the control cabinet 3 controls the horizontal electric push rod 24 and the polishing machine 26 to work simultaneously. The horizontal electric push rod 24 drives the polishing machine 26 to move towards the rough area of the stainless steel plate, and uses the polishing machine 26 to polish the rough area.After the third electric push rod 231 drives the polishing machine 26 to reciprocate left and right for a while, the control cabinet 3 will control the third electric push rod 231 to drive the polishing machine 26 to move upward, and drive the polishing machine 26 to move to the initial position through the fourth lead screw linear module 29. Then, the control cabinet 3 controls the opening and closing valve 41 in the corresponding air discharge pipe 40 to open, so that the gas in the pneumatic cavity 18 is discharged. Under the action of the spring force, the piston plate 21 will drive the bent rod 22, the moving plate 8 and the laser positioning sensor 9 to move together towards the polished area to re-detect this area (since it has been polished, a change in size of 0.01 - 0.05 mm is allowed), thus avoiding the problem that the rough surface of the stainless steel plate will interfere with the measurement accuracy of the laser positioning sensor 9.,

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.,
