Abstract
Description

[0002] In the lithium battery industry, there are coating machines and roll presses, and in the steel industry, precision steel plate rolling mills, etc. These rolling mill equipment need to be equipped with precision rolls of different diameters in pairs. The surface roughness and straightness of the two rolls determine the uniformity and consistency of the thickness of the rolled product. After the rolls are precision ground on a high-precision grinder, we need to measure and detect the gap between the two rolls at different angles to judge the straightness of the rolls. By distinguishing the size of the gap through the light passing through the gap, we can judge whether the straightness of the rolls meets the technical requirements.
[0003] For the straightness of the existing rolls, a micrometer is often used as a measuring tool to cross-measure in the middle and at both ends to confirm whether the roll diameter is qualified. Then, two people manually lean the two rolls together, and through the naked eyes of the inspector, observe the brightness and color of the light passing through the gap to judge the size of the roll gap, and then judge the straightness of the two rolls. This measurement method and the manual alignment of the roll gap and the naked-eye observation of the color of the light bring great uncertainty to the accuracy of the measurement and observation of the color of the light due to the limitations of the employees' own qualities, and the detection error is relatively large.

[0024] Please refer to Figures 1 to 3, a roll straightness detection device provided by the present utility model will be described hereinafter. A roll straightness detection device includes a workbench 1. On the upper end surface of the workbench 1, two support seats 2 are arranged at intervals. On the upper end surfaces of the support seats 2, a fixed support 3 is fixedly arranged and a movable support 4 is slidably arranged respectively. The fixed supports 3 on the two support seats 2 are used to jointly support and fix the fixed roll 27, and the movable supports 4 on the two support seats 2 are used to jointly support the movable roll 28. A detection gap is formed between the movable roll 28 and the fixed roll 27. A light source assembly is arranged on the upper end surface of the workbench 1. The light source assembly is located between the two support seats 2 and below the detection gap. An adjustable-height adjusting frame 5 is jointly installed on the upper end surfaces of the two support seats 2. The top of the adjusting frame 5 has a detection cross beam 6 spanning above the detection gap. The length direction of the detection cross beam 6 is consistent with the length direction of the detection gap, and a plurality of color recognition sensors 7 are arranged at intervals in sequence along the length direction of the detection cross beam 6.
[0025] For a roll straightness detection device provided by the present utility model, compared with the prior art, two support seats 2 are arranged on the workbench 1, and a fixed support 3 and a movable support 4 are arranged on each support seat 2. The two fixed supports 3 on the two support seats 2 are arranged correspondingly, and the two movable supports 4 on the two support seats 2 are arranged correspondingly. Two rolls (fixed roll 27 and movable roll 28) are respectively placed on the two fixed supports 3 and the two movable supports 4. According to the specifications of the two rolls, the two movable supports 4 are moved simultaneously, so as to drive the movable roll 28 to approach the fixed roll 27, and a detection gap is formed between the movable roll 28 and the fixed roll 27. The height of the above-mentioned adjusting frame 5 is adjusted, and the detection cross beam 6 of the adjusting frame 5 is located directly above the detection gap and the length direction is consistent with the length direction of the detection gap. A plurality of color recognition sensors 7 on the detection cross beam 6 are arranged at intervals in sequence along the length direction of the detection gap. The light source assembly below the detection gap is turned on, and the light emitted by the light source assembly forms different colors after passing through the detection gap. The plurality of color recognition sensors 7 determine the gap values at each position of the detection gap by identifying the colors of the light, and finally obtain the straightness of the gap between the fixed roll 27 and the movable roll 28. A roll straightness detection device provided by the present utility model can replace manual operation to detect the straightness of two rolls, and greatly reduce the detection error.
[0026] It should be noted that: The color recognition sensor 7 is an RGB color recognition sensor 7, which is a sensor that recognizes various colors through the changes in the three color channels of red (R), green (G), and blue (B) and their mutual superposition. The size of the detection gap is judged according to the transmitted light color, so as to obtain the straightness of the two rollers. Specifically, if the gap is greater than 2.5 μm, the transmitted light color is white light; when the gap is 1 - 2 μm, the transmitted light color is red light; when the gap is 1 μm, the transmitted light color is blue light; when the gap is less than 1 μm, the transmitted light color is purple light; when the gap is less than 0.5 μm, there is no light transmission.
[0027] Specifically, the number of color recognition sensors 7 is three, one in the middle of the detection crossbeam 6 and one on each side of the detection crossbeam 6, which can fully cover the detection gap and avoid detection blind spots. In addition, when the axial lengths of the fixed roller 27 and the moving roller 28 are relatively long, the number of color recognition sensors 7 can also be appropriately increased, which will not be elaborated here.
[0028] In addition, lifting rods are respectively provided on both sides of the adjusting frame 5, and the detection crossbeam 6 is connected to the upper ends of the two lifting rods. Among them, the lifting rod is a sleeve structure sleeved integrally, and the overall damping lifting can be realized by pulling the sleeve, so as to achieve the purpose of adjusting the height of the detection crossbeam 6.
[0029] Preferably, a light-transmitting plate 8 is provided below the detection crossbeam 6, and the light-transmitting plate 8 is located directly above the detection gap. The light-transmitting plate 8 is white, the length of the light-transmitting plate 8 can completely cover the axial length of the installed rollers, and the middle area of the width of the light-transmitting plate 8 is aligned with the detection gap, which can effectively collect the light after passing through the detection gap under the fixed roller 27 and the moving roller 28.
[0030] Specifically, the light source assembly includes a light source bracket and a lamp tube 9 installed on the light source bracket. The lamp tube 9 is arranged below the detection gap along the length direction, the length direction of the lamp tube 9 can completely cover the length direction of the detection gap, the lamp tube 9 is a fluorescent lamp, and the white light emitted passes through the detection gap. The size of the detection gap determines the color of the light after passing through the detection gap.
[0031] A slide rail 10 is arranged on the upper end surface of the support base 2 along the length direction. A slider 11 is arranged at the lower end of the movable support 4, and the slider 11 is slidably arranged on the slide rail 10. One end of the upper end surface of the support base 2 close to the movable support 4 is provided with a first linear drive mechanism 12. The first linear drive mechanism 12 is connected to the movable support 4 and is used to drive the movable support 4 to slide along the length direction of the slide rail 10. The first linear drive mechanism 12 is a lead screw drive mechanism, and its lead screw penetrates through the movable support 4 and is in threaded fit. Under the sliding limit of the slider 11 and the slide rail 10, the motor of the lead screw drive mechanism drives the lead screw to rotate, so as to drive the movable roller 28 to approach or move away from the fixed roller 27 through the movable support 4, so as to realize the adjustment of the relative position of the movable roller 28 and the fixed roller 27. With the above design, the device can be applied to the detection of rolling rollers with different roller diameters.
[0032] In addition, a second linear drive mechanism 13 is arranged on the upper end surface of the workbench 1. The second linear drive mechanism 13 is connected to any one of the support bases 2 and is used to drive any one of the support bases 2 to move away from or close to the other support base 2. The second linear drive mechanism 13 is a lead screw drive mechanism, and its lead screw penetrates through any one of the support bases 2 and is in threaded fit. This support base 2 is slidably matched with the work platform. The power end of this lead screw drive mechanism adopts a handwheel structure. Rotating the handwheel drives the lead screw to rotate, so as to drive this support base 2 to move away from the other support base 2. With the above design, the device can be applied to the detection requirements of rolling rollers with different axial lengths.
[0033] Please refer to Figure 3 , a displacement sensor 14 is installed on one side of the movable support 4 close to the fixed support 3. The displacement sensor 14 is used to detect the displacement of the movable support 4. The displacement sensor 14 can detect the displacement distance of the movable support 4 or the distance relative to the fixed support 3, so as to stop it after the movable support 4 moves in place or send a signal to the corresponding controller.
[0034] Two rotating wheels 15 are arranged on the tops of the fixed support 3 and the movable support 4. The two rotating wheels 15 are arranged at intervals to support the shaft ends of the movable roller 28 and the fixed roller 27, which can ensure the stability of the movable roller 28 and the fixed roller 27. At the same time, the cooperation of the two rotating wheels 15 with the shaft ends of the movable roller 28 and the fixed roller 27 can realize the self-rotation of the movable roller 28 and the fixed roller 27.
[0035] On the outer side surface of any one of the moving supports 4, a rotating motor 16 and a tensioning frame are respectively arranged. A driving wheel 17 is arranged at the driving end of the rotating motor 16, a tensioning wheel 18 is arranged on the tensioning frame, and a driven wheel 19 is arranged at the shaft end of the moving roller 28 on the side close to the rotating motor 16. A synchronous belt 20 is wound around the driving wheel 17, the tensioning wheel 18 and the driven wheel 19. The tensioning wheel 18 can move close to or away from the rotating motor 16 so as to adjust the tightness of the synchronous belt 20 through the tensioning wheel 18. The tensioning frame moves in the direction away from the rotating motor 16, thereby tensioning the synchronous belt 20. After measuring the straightness of the detection gap between the fixed roller 27 and the moving roller 28 once, the rotating motor 16 is started. The driving wheel 17 of the rotating motor 16 drives the synchronous belt 20 to rotate, thereby driving the moving roller 28 to rotate through the driven wheel 19. The moving roller 28 stops after rotating by an angle of 90° once, and the straightness detection is carried out again, and then it rotates by 90° in turn for measurement until the measurement of the entire circumferential circle of the moving roller 28 is completed. When the measurement of the circumferential circle of the moving roller 28 is completed, the positions of the moving roller 28 and the fixed roller 27 can be moved relative to each other, and the above process is repeated, and the straightness detection of different circumferential regions of the two rollers can be completed.
[0036] Specifically, the tensioning frame includes an adjusting plate 21 and a tensioning shaft 22. A long slot 23 is formed in the adjusting plate 21, and an adjusting screw 24 connected to the outer side surface of the moving support 4 penetrates through the long slot 23. The tensioning shaft 22 is vertically and fixedly arranged on the outer side surface of the adjusting plate 21, and the tensioning wheel 18 is rotatably installed at the end of the tensioning shaft 22. An adjusting block 25 is fixed on the side of the adjusting plate 21 close to the rotating motor 16. An adjusting rod 26 is horizontally threaded through the adjusting block 25. Rotating the adjusting rod 26 can push the adjusting plate 21 to move in the direction away from the rotating motor 16. At this time, the long slot 23 of the adjusting plate 21 moves under the limitation of the adjusting screw 24, and the adjusting plate 21 tensions the synchronous belt 20 through the tensioning shaft 22 and the tensioning wheel 18. When the synchronous belt 20 needs to be replaced or repaired, reversing the rotation of the adjusting rod 26 can make the synchronous belt 20 drive to a relaxed state, which is convenient for disassembly.
[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
