Description

Technical Field

[0001] The invention relates to the technical field of material processing, and in particular to a fully automatic flatness calibration device based on laser ranging. Background Art

[0002] During the material processing, the flatness of the plate directly affects the quality of its subsequent processing and use. Traditional plate leveling equipment usually completes the leveling operation by manually adjusting the distance between the roller and the plate. This method has the following shortcomings: First, the manual adjustment process is cumbersome and inefficient, and it is difficult to meet the needs of mass production; second, when dealing with plates of different widths, traditional equipment has difficulty in adjusting the roller and the limit mechanism, which can easily lead to inaccurate positioning and affect the processing accuracy of the plate; third, the lack of precise measurement devices makes it impossible to feedback the flatness status of the plate in real time, making the leveling effect less than ideal.

[0003] In response to the above problems, some modern leveling equipment has introduced laser ranging technology and automatic adjustment mechanisms. However, the existing leveling equipment based on laser ranging still has the following technical bottlenecks in application: on the one hand, when the width of the plate changes, the measurement angle and position of the laser ranging sensor are difficult to adapt quickly, resulting in a decrease in measurement accuracy; on the other hand, the equipment's ability to guide and limit the plate during feeding is insufficient, and the plate is prone to offset or collision during feeding, affecting the leveling effect. In addition, the existing equipment is not flexible enough to adjust the plate thickness to different levels, and cannot meet the diverse leveling needs well. Summary of the invention

[0032] Embodiment 2: In order to verify the effect of synchronous lifter and adjusting roller in leveling plates with different thicknesses, aluminum alloy plates (model 6061-T6) with thicknesses of 2mm, 5mm, 8mm, 12mm and 15mm were selected; the equipment used a synchronous lifter (model LGMX-150) to adjust the height of the lifting seat, and the gap between the adjusting roller and the fixed roller was set to be equal to or 0.2mm to 0.5mm less than the thickness of the plate according to the thickness of the plate.

[0033] In the experiment, the flatness error (in μm) of the plate after passing through the leveling equipment was recorded. The experimental conditions controlled the ambient temperature to 25°C, the humidity to 50%, and the plate feeding speed to 20 m / min.

[0034]

[0035] The results show that controlling the gap between the adjusting roller and the fixed roller within the range below the plate thickness can significantly improve the leveling effect, and the flatness error is less than 20μm; compared with the error range (50μm to 100μm) of traditional equipment (the gap is greater than the plate thickness), this equipment significantly improves the leveling accuracy.

[0036] Embodiment 3: In order to verify the adaptability of the feeding limit mechanism to plates of different widths, cold-rolled steel plates (SPCC model) with widths of 500 mm, 800 mm, 1000 mm, 1200 mm and 1500 mm were selected; the first bidirectional screw was driven by a servo motor (YASKAWASGMAH-04AAA61) to adjust the moving seat so that the distance of the moving seat was equal to the width of the plate to ensure uniform limiting on both sides. The offset (in mm) during the plate feeding process was recorded in the experiment.

[0037] The experimental conditions controlled the servo motor speed to 300 rpm, the feed speed to 20 m / min, and other variables remained the same.

[0038]

[0039] Experimental results show that when the distance of the moving seat is equal to the width of the plate, the offset is controlled within 0.3mm, ensuring high stability of feeding; compared with the traditional limit mechanism (the limit width is greater than the width of the plate, and the offset is 2mm to 5mm), this design ensures feeding stability and leveling effect while achieving efficient feeding.

[0040] Embodiment 4: In order to verify the flexibility of the laser ranging installation mechanism in leveling plates of different thicknesses, copper plates (model C1100) with thicknesses of 1 mm, 3 mm, 6 mm, 9 mm and 12 mm were selected; the laser ranging sensor (model Keyence LK-G5000) adjusted the height through the tooth plate and lifting screw to achieve accurate measurement of plates of different thicknesses.

[0041] The experiment records the surface waviness (in μm) of the plate after leveling. The smaller the waviness, the better the leveling effect. The leveling effect of the laser ranging sensor without adjustment is compared.

[0042]

[0043] The results show that the laser ranging sensor significantly reduces the corrugation of the plate by dynamically adjusting the height, and the leveling effect is improved by about 60% compared with traditional fixed-position laser sensors.

[0044] Embodiment 5: In order to verify the improvement of the feed guide mechanism on the stability of the plate entering the equipment, aluminum plates (model 3003-H14) with widths of 600 mm, 800 mm, 1000 mm, 1200 mm and 1400 mm were selected; the trumpet-shaped opening angle was adjusted by fixing the fan-shaped plate and the mounting rod, and the lateral deviation of the plate during the guiding process was recorded (in mm).

[0045] The experimental conditions controlled the sheet material feeding speed to be 2.5 m / min and the sliding friction coefficient between the slider and the track groove to be 0.02.

[0046]

[0047] Experimental results show that the feed guide mechanism significantly reduces the lateral deviation of the plate, especially in plates with wider widths, where the adjustment ability of the guide mechanism is particularly outstanding; compared with traditional linear guide mechanisms, the deviation is reduced by about 70%.

[0048] Working principle: When in use, the distance of the moving seat 26 is controlled according to the width of the plate to be leveled, and the servo motor 25 is started to drive the first bidirectional screw 24 to rotate. Since the two moving seats 26 are respectively screwed on different thread surfaces of the first bidirectional screw 24, the two moving seats 26 can be guaranteed to move synchronously and be consistent with the center distance to ensure that the plate to be leveled is placed in the center position of the feed limit mechanism 2, pushing the material to move inward, and the adjusting rollers 17 on both sides can limit the two sides of the material to ensure stability during feeding and keep it in the center. After the plate is pushed into the leveling machine body 1, it will be driven inward by the feed roller 18, and the plate will be leveled by multiple fixed rollers 14 and adjusting rollers 17. The height of the lifting seat 16 can be controlled by the synchronous elevator 15 on the top, and then the distance between the adjusting roller 17 and the fixed roller 14 can be controlled to adapt to different leveling tasks.

[0049] When the width of the plate changes, the movable seat 26 will move to adapt to plates of different widths, and then the second limit shaft 28 will move. The movement of the second limit shaft 28 can drive the tooth plate 39 to move horizontally. The limit block 132 can limit the tooth plate 39 so that the tooth plate 39 can only move horizontally. During the movement of the tooth plate 39, the lifting screw 31 can be driven to rotate by the gear 32. When the lifting screw 31 rotates, it can drive the movable block 33 to move up and down, and then adjust the height of the second bidirectional screw 34 to adjust the height of the laser ranging sensor 38. The laser ranging sensor 38 measures the plate entering the body to determine whether the current mode meets the leveling requirements. If the requirements cannot be met, the control system will control the height of the lifting seat 16 through the synchronous elevator 15 according to the collected signal, and then automatically adjust the gap between the fixed ring 14 and the adjusting roller 17 to meet the leveling requirements.

[0050] The thread direction of the lifting screw 31 must ensure that the second limit axis 28 moves outward when the width of the plate increases, so as to drive the laser ranging sensor 38 to move upward and expand the viewing angle of the laser ranging. Conversely, when the width of the plate decreases, the second limit axis 28 moves closer, and the laser ranging sensor 38 is lowered to improve the measurement accuracy. When in use, the adjustment block 35 can be driven to move by manually rotating the second bidirectional screw 34, and it is ensured that the two adjustment blocks 35 move synchronously in opposite directions. When the adjustment block 35 moves, the laser ranging sensor 38 can be driven to move by the connecting rod 36 to adjust the position of the laser ranging sensor 38, thereby improving the flexibility of the equipment when in use.

[0051] When the plate is fed, the plate can be guided by the feed guide mechanism 4 on both sides so that the plate can smoothly enter between the two movable seats 26. Since the front end of the mounting rod 43 is tilted outward, the two mounting rods 43 are trumpet-shaped. When the plate is fed, the two sides are limited by the extension rod 47. When the plate is pushed for feeding, the smoothness of feeding can be ensured by the rotation of the sleeve 48, and the plate is guided to enter between the two movable seats 26. The opening size of the two feed guide mechanisms 4 can be flexibly adjusted. After rotating the mounting rod 43, it can be kept fixed by the locking bolt 44 and the corresponding positioning hole 42. Since the extension rod 47 is placed between the two auxiliary rollers 22, the slider 46 can move freely to achieve self-adaptation during the angle adjustment of the mounting rod 43, and the front end sleeve 49 rotates on the outermost auxiliary roller 22, which can improve the stability of the mounting rod 43 and prevent displacement due to impact during plate feeding.
