Description

Technical Field

[0001] The present invention relates to the technical field of rubber roller detection, and particularly to a device and method for detecting the surface flatness of a rubber roller. Background Art

[0002] As a key functional component in modern industrial manufacturing, the surface flatness of a polyurethane rubber roller directly affects the finished product quality and production efficiency in high-end manufacturing fields such as printing and papermaking. Traditional contact detection uses calipers or profilometers for manual measurement, and there are two major technical bottlenecks: one is that the contact between the measuring tool and the elastic material is likely to cause surface damage, and the other is that it is difficult for manual operation to eliminate measurement errors.

[0003] The non-contact detection technology of laser displacement sensors effectively solves this industry pain point. This technology obtains surface topography data through laser beam scanning, avoiding physical damage to the surface of elastic materials during traditional contact measurement while maintaining measurement accuracy. However, the high reflectivity of polyurethane materials leads to signal interference during laser measurement. Therefore, researchers innovatively improved it by spraying matte powder on the polyurethane rubber roller, and the measurement accuracy was improved by reducing the surface reflectivity.

[0004] After successfully completing the precise detection of the surface flatness of the polyurethane rubber roller, it is very necessary to remove the matte powder in a timely and effective manner. On the one hand, it avoids the performance interference of the matte powder on the polyurethane rubber roller (such as changing the friction coefficient or corroding the polyurethane material, resulting in cracking, hardening, etc.), and on the other hand, it avoids the residual matte powder affecting the subsequent use of the polyurethane rubber roller. The traditional cleaning method usually involves removing the detected polyurethane rubber roller from the production line or detection equipment and then moving it to a dedicated cleaning area for cleaning. This operation not only requires the transportation of the polyurethane rubber roller, increasing the complexity of the operation, but also during the process of disassembling the polyurethane rubber roller for cleaning, the matte powder already sprayed on its surface is very likely to fall off due to reasons such as vibration and friction.

[0005] Therefore, it is urgent to develop a device and method for detecting the surface flatness of a rubber roller to replace the traditional cleaning method and make the cleaning of matte powder more efficient and environmentally friendly. Summary of the Invention

[0029] As a further solution of the present invention: a method for detecting the surface flatness of a rubber roller, using the above-mentioned device for detecting the surface flatness of a rubber roller, includes the following steps:

[0030] Step 1, installation detection: Spray matte powder on the rubber roller, and then install it on the fixing mechanism to fix the rubber roller. After fixing, the controller controls the linear module to drive the laser displacement sensor to move, and synchronously controls the first servo motor to drive the rubber roller to rotate. The laser displacement sensor obtains detection data in real time, records it, and transmits it to the controller for data processing to obtain the detection result;

[0031] Step 2, primary cleaning: After detection, start the two groups of second servo motors synchronously. The second servo motor drives the drive screw to rotate. The drive screw drives the second bearing seat to move. The second bearing seat drives the dust suction head to move towards the installed rubber roller. When it moves to the set position, start the adjustment motor to drive the adjustment frame to rotate, adjust the corresponding position of the working surface of the dust suction head and the surface of the rubber roller, and perform adsorption;

[0032] Step 3. Secondary cleaning: After adsorption, start the lifting motor to drive the rotating rod to rotate. The rotating rod drives the transmission gear to rotate, and the transmission gear drives the rack to move upward. The rack drives the dust collection guide table to move upward. Synchronously start the drive motor to drive the rotating shaft to rotate. The rotating shaft drives the scraper to contact the surface of the rubber roller shaft, scraping off stubborn residual matte powder. At the same time, the linkage rope pulls the dust collection guide table to lift one end, approaching the surface of the rubber roller shaft, and start the adjustment motor to drive the adjustment bracket to rotate, adjusting the position of the dust suction head so that the dust suction head corresponds to the dust collection guide table, causing the scraped matte powder to fall on the dust collection guide table and then slide down to be adsorbed by the dust suction head.

[0033] Advantages of the present invention:

[0034] In the present invention, by synchronously starting two sets of servo motors II, the servo motor II drives the drive screw to rotate, the drive screw drives the bearing block II to move, and the bearing block II drives the dust suction head to move towards the installed rubber roller. When moving to the set position, start the adjustment motor to drive the adjustment bracket to rotate, adjusting the corresponding position of the working surface of the dust suction head and the surface of the rubber roller (ensuring that the dust suction head is tangent to the rubber roller shaft surface), so that the dust suction head is close to the rubber roller shaft surface, improving the sufficiency of adsorption.

[0035] In the present invention, the drive motor drives the rotating shaft to rotate, driving the first clamping plate and the second clamping plate to flip around the axis of the rotating shaft, and then driving the scraper to contact the surface of the rubber roller shaft, scraping off stubborn residual matte powder. When the secondary cleaning assembly deflects to operate on the surface of the rubber roller shaft, the linkage rope will pull the dust collection guide table to lift its tail, approaching the surface of the rubber roller shaft, shortening the falling stroke of the matte powder in the air, reducing the diffusion caused by the disturbance of the air flow, causing the scraped matte powder to fall on the dust collection guide table and then slide down to be adsorbed by the dust suction head, further realizing the cleaning of the matte powder, avoiding the scattered matte powder particles from falling off and floating in the air and being inhaled by the operator, causing irritation or damage to their respiratory system, and even causing more serious health problems in the long term.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0047] As Figures 1 - 8 shown, the present invention provides a device for detecting the surface flatness of a rubber roller. The device includes a detection platform 1, a fixing mechanism 2 is installed on the top of the detection platform 1, a detection component 4 is arranged on the top of the fixing mechanism 2, and a dust collection component 3 is arranged on the front side (taking Figure 1 as the basic perspective) of the fixing mechanism 2, a secondary cleaning component 5 is arranged on the back side of the fixing mechanism 2, and a dust collection and guiding component 6 is arranged at the bottom of the fixing mechanism 2, wherein the dust collection and guiding component 6 is connected to the secondary cleaning component 5 to achieve associated movement.

[0048] It should be further noted that the detection platform 1 in the present invention can be fixed or mobile, that is, the detection platform 1 can be rotated among multiple workshops. The moving structure at the bottom of the detection platform 1 is a prior art and will not be elaborated here.

[0049] In the present invention, the produced rubber roller 100 (polyurethane type) is pre-sprayed with matte powder, and then installed on the fixing mechanism 2. The two sides of the rubber roller 100 are fixed. After fixing, the controller is turned on, and the rubber roller 100 is controlled to rotate by the controller. Then, real-time detection is carried out through the detection component 4. After detection, the data is processed by the controller to obtain the detection result.

[0050] After detection, the rubber roller 100 sprayed with matte powder is closely adsorbed by the dust suction component 3. After adsorption, the stubborn residual matte powder on the rubber roller 100 is secondarily cleaned by the secondary cleaning component 5. During cleaning, the dust suction component 3 and the dust collection and guiding component 6 are cooperated to adsorb the shed residues again sufficiently, avoiding environmental pollution at the cleaning site caused by the shedding of matte powder, increasing the difficulty and cost of subsequent cleaning, and at the same time cleaning the rubber roller 100 sufficiently to avoid the influence of matte powder residue on the performance and use of the rubber roller 100.

[0051] Furthermore, as Figure 2 and Figure 3 shown, the above-mentioned detection platform 1 includes a detection frame 11. A storage box 12 and a waste box 15 are arranged in the middle of the detection frame 11. A storage cover plate 13 is arranged on the top of the storage box 12. The storage box 12 is located on the side of the detection frame 11 close to the manual operation side. By constructing a storage space, other structures such as connecting pipelines after use are stored and sorted to ensure a clean and orderly detection environment. The above-mentioned waste box 15 is used to collect a small amount of matte powder shed during installation or rotation, avoiding secondary excitation and dispersion in the air.

[0052] Moreover, mounting base plates 14 are arranged on the top surfaces at both ends of the detection frame 11 to carry other components, making installation and disassembly more convenient and the maintenance cost lower. An fixing plate is fixedly arranged on the inner section of each mounting base plate 14. The fixing plate is used to limit the detection space and carry the secondary cleaning component 5.

[0053] Furthermore, as Figure 1 and Figure 2 shown, the fixing mechanism 2 in the present invention includes a mounting base one 21 and a mounting base two 24 fixed on the two side mounting base plates 14. Bearing seats one 22 are arranged on both the mounting base one 21 and the mounting base two 24. The two bearing seats one 22 are symmetrically arranged. A servo motor one 23 is also installed on the mounting base one 21. The servo motor one 23 provides driving force for the rubber roller 100.

[0054] It should be further explained that the bearing seat 1-22 in the present invention is a combined structure, which is composed of a lower half bearing seat and an upper half bearing seat. The upper half bearing seat is detachably connected to the lower half bearing seat to limit the bearing during installation. When the rubber roller 100 is installed on the bearing seat 1-22, first connect the rotating shafts at both ends of the rubber roller 100 to the bearings adapted to the bearing seat 1-22, and then install and fix it on the bearing seat 1-22. Further, connect the output shaft of the servo motor 1-23 to the rotating shaft at one end of the rubber roller 100 to drive the rubber roller 100.

[0055] Further, as Figure 2 and Figure 3 shown, the above-mentioned detection assembly 4 includes a detection frame 41 perpendicular to the detection platform 1. Both ends of the detection frame 41 are respectively connected to the corresponding mounting base 1-21 or mounting base 2-24, and the detection frame 41 is in an inverted L shape with its short side facing upward. An installation groove is provided on the bottom surface of the short side of the detection frame 41, and a linear module 42 is fixedly installed in the installation groove. A connecting plate is installed on the moving seat of the linear module 42, and a laser displacement sensor 43 is installed on the bottom surface of the connecting plate.

[0056] In the present invention, the laser displacement sensor 43 can be Keyence LK-G5000 or other triangulation or coaxial optical path sensors. Its specific structure is prior art and will not be elaborated here. And the linear module 42 in the present invention is also prior art to realize the linear position adjustment of the laser displacement sensor 43.

[0057] It should be noted that a controller is also provided on the detection platform 1 in the present invention. The controller can be a PLC controller, and the controller is electrically connected to the servo motor 1-23, the linear module 42, and the laser displacement sensor 43.

[0058] After the rubber roller 100 to be detected is installed on the fixing mechanism 2, the controller controls the linear module 42 to drive the laser displacement sensor 43 to move, and synchronously controls the servo motor 1-23 to drive the rubber roller 100 to rotate (the rotation speed can be 1 rpm, axial step: 0.1 mm / turn). The detection data is obtained in real time by the laser displacement sensor 43, recorded, and transmitted to the controller for data processing to obtain the detection result (the detection result can be a 3D topography map or a Ra / Rz distribution histogram or a cylindricity error table).

[0059] Among them, using the laser displacement sensor 43 to detect the surface flatness of the rubber roller 100 is prior art and will not be elaborated here.

[0060] It should be further noted that multiple laser displacement sensors 43 can be coaxially arranged in the present invention. The multiple laser displacement sensors 43 are arranged along the axis of the rubber roller 100 to achieve full-length coverage and shorten the detection time.

[0061] Further, as Figures 1 - 3 and Figure 5 shown, the dust collection assembly 3 in the present invention includes slide rails 37 provided on two groups of mounting base plates 14. A slider 38 is slidably arranged on the slide rails 37. A moving plate 34 is mounted on the top of the slider 38. Second bearing seats 31 are arranged on the moving plate 34. The second bearing seats 31 have the same structure as the first bearing seats 22, and only the mounting shaft diameter is selected according to actual requirements. A driving screw 36 is threadedly connected to the lower half shaft seat of the second bearing seat 31. One end of each driving screw 36 is connected to a second servo motor 35, and the two second servo motors 35 are both fixed on the mounting base plate 14.

[0062] An adjusting frame 32 is rotatably arranged between the two second bearing seats 31. Multiple groups of dust suction heads 33 are mounted on the adjusting frame 32. The multiple groups of dust suction heads 33 are connected to an external industrial vacuum cleaner (with a HEPA filter) or a dust suction pipeline system through connecting pipes. An adjusting motor 39 is further arranged on one side of the moving plate 34. The output shaft of the adjusting motor 39 is connected to the rotating shaft at one end of the adjusting frame 32 to drive the rotation of the adjusting frame 32 on the second bearing seat 31.

[0063] During use, by synchronously starting the two second servo motors 35, the second servo motors 35 drive the driving screws 36 to rotate. The driving screws 36 drive the second bearing seats 31 to move. The second bearing seats 31 drive the dust suction heads 33 to move towards the installed rubber roller 100. When moving to the set position, start the adjusting motor 39 to drive the adjusting frame 32 to rotate, adjust the corresponding position of the working surface (i.e., the mouth part) of the dust suction head 33 and the surface of the rubber roller 100 (ensure that the dust suction head 33 is tangent to the axial surface of the rubber roller 100), and make the dust suction head 33 close to the axial surface of the rubber roller 100 to improve the sufficiency of adsorption.

[0064] It should be further noted that the dust collection assembly 3 in the present invention can also be used during installation to adsorb the falling matte powder during the installation process, but direct suction should be avoided to affect subsequent detection.

[0065] Further, in order to fully clean the stubborn matte powder remaining on the rubber roller 100 after being adsorbed by the dust collection assembly 3, the present invention further provides a secondary cleaning assembly 5, as Figures 1 - 4 shown. The secondary cleaning assembly 5 includes a rotating shaft 52 rotatably mounted on the two side fixing plates. One end of the rotating shaft 52 is connected to a driving motor 51, and the driving motor 51 is fixed on the outer side surface of the fixing plate to drive the rotating shaft 52. Sleeve rings 53 are symmetrically sleeved on the rotating shaft 52. The sleeve rings 53 can be fixed on the rotating shaft 52 through pins. The two sleeve rings 53 are cooperatively connected with a first clamping plate 54. A second clamping plate 55 is arranged on the first clamping plate 54. A scraper 56 is clamped between the outer sides of the first clamping plate 54 and the second clamping plate 55.

[0066] The rotating shaft 52 is driven to rotate by the driving motor 51, driving the first clamping plate 54 and the second clamping plate 55 to flip around the axis of the rotating shaft 52, and further driving the scraping plate 56 to be in surface contact with the shaft surface of the rubber roller 100 to scrape off stubborn residual matte powder.

[0067] It should be noted that the scraping plate 56 of the present invention can also be replaced by a nylon soft brush for cleaning.

[0068] Furthermore, since the scraping plate 56 scrapes off the residual matte powder on the shaft surface of the rubber roller 100, the scraped-off matte powder residue will fall off, and the fallen matte powder is prone to diffusion under the influence of external factors (such as air) during the process of falling into the waste bin 15, affecting the working environment.

[0069] The present invention is also provided with a dust collection and guiding assembly 6 for timely receiving the fallen matte powder and shortening the falling stroke of the matte powder in the air. The dust collection and guiding assembly 6 includes a dust collection and guiding table 67. Pulling rings are symmetrically arranged at the tail of the dust collection and guiding table 67, and pulling rings are also arranged on the two sleeve rings 53. A linkage rope 68 is connected between a corresponding set of pulling rings. When the secondary cleaning assembly 5 deflects to operate on the shaft surface of the rubber roller 100, the linkage rope 68 will pull the dust collection and guiding table 67 to lift its tail, approaching the shaft surface of the rubber roller 100, shortening the falling stroke of the matte powder in the air and reducing the diffusion caused by the disturbance of the air flow.

[0070] And further, in order to adjust the position of the dust collection and guiding table 67 and the shaft surface of the rubber roller 100, the present invention is also provided with a positioning base 63. The two positioning bases 63 are fixed on the fixing plates on both sides, and a rotating rod 62 is rotatably arranged between the two positioning bases 63. Transmission gears are arranged at both ends of the rotating rod 62, and a toothed rod 64 is also slidably sleeved on one side of the two positioning bases 63. The toothed rod 64 is meshed and connected with the transmission gear, and the toothed rod 64 is driven to move up and down by the transmission gear. Bevel platforms 65 are arranged at the tops of the toothed rods 64, and a connecting seat 66 is also arranged at the bottom of the front end of the dust collection and guiding table 67. The corresponding connecting seat 66 is rotatably arranged at one end of the bevel platform 65 through a rotating shaft. When the linkage rope 68 pulls the tail end of the dust collection and guiding table 67, the dust collection and guiding table 67 deflects around the rotating shaft.

[0071] An elevating motor 61 is installed outside the second installation base 24. The output shaft of the elevating motor 61 penetrates through the second installation base 24 and is connected to one end of the rotating rod 62. By driving the elevating motor 61 to drive the rotating rod 62 to rotate, the rotating rod 62 drives the transmission gear to rotate, and the transmission gear drives the toothed rod 64 to move up and down, further realizing the adjustment of the position of the dust collection and guiding table 67, so that the scraped-off matte powder falls on the dust collection and guiding table 67 and then slides down to be adsorbed by the dust suction head 33, further realizing the cleaning of the matte powder.

[0072] In the present invention, the dust collection and material guiding table 67 is initially supported on the inclined table 65, and after being pulled by the linkage rope 68, it disengages from the inclined table 65 and further tilts.

[0073] When the present invention works, the produced rubber roller 100 is pre-sprayed with matte powder, and then installed on the fixing mechanism 2 to fix both sides of the rubber roller 100. After fixing, the linear module 42 is controlled by the controller to drive the laser displacement sensor 43 to move, and at the same time, the servo motor 1 23 is controlled to drive the rubber roller 100 to rotate. The detection data is obtained in real time by the laser displacement sensor 43, recorded, transmitted to the controller for data processing, and the detection result is obtained.

[0074] After detection, two groups of servo motors 2 35 are started synchronously. The servo motor 2 35 drives the driving screw 36 to rotate, the driving screw 36 drives the bearing block 2 31 to move, and the bearing block 2 31 drives the dust suction head 33 to move towards the installed rubber roller 100. When it moves to the set position, the adjustment motor 39 is started to drive the adjustment frame 32 to rotate, and the working surface of the dust suction head 33 is adjusted to correspond to the surface position of the rubber roller 100 for adsorption.

[0075] After adsorption, the lifting motor 61 is started to drive the rotating rod 62 to rotate. The rotating rod 62 drives the transmission gear to rotate, the transmission gear drives the toothed rod 64 to move upward, the toothed rod 64 drives the dust collection and material guiding table 67 to move upward. The driving motor 51 is started synchronously to drive the rotating shaft 52 to rotate. The rotating shaft 52 drives the first clamping plate 54 and the second clamping plate 55 to flip around the axis of the rotating shaft 52, thereby driving the scraping plate 56 to contact the axial surface of the rubber roller 100 to scrape off stubborn residual matte powder. At the same time, the linkage rope 68 will pull the dust collection and material guiding table 67 to lift its tail, further approaching the axial surface of the rubber roller 100, and the adjustment motor 39 is started to drive the adjustment frame 32 to rotate to adjust the position of the dust suction head 33 so that the dust suction head 33 corresponds to the front end of the dust collection and material guiding table 67, so that the scraped matte powder falls on the dust collection and material guiding table 67 and then slides down to be adsorbed by the dust suction head 33.
