Description

Technical Field

[0001] This application relates to the field of paper positioning and transmission devices, and particularly to an air-floating guide rail type high-precision seal paper positioning and transmission device. Background Art

[0002] In modern industrial production, high-precision material positioning and transmission technologies are of great significance for improving product manufacturing efficiency and quality. Especially in industries such as printing and packaging, the precise positioning and stable transmission of thin materials such as paper directly affect the qualification rate of the final products. With the continuous improvement of the automation level, higher requirements are put forward for the accuracy, stability and adaptability of transmission devices. Therefore, developing a transmission device that can meet the high-precision positioning requirements has become an inevitable trend in the industry development.

[0003] Currently, to achieve the positioning and transmission of thin materials such as paper, the industry usually adopts mechanical contact type guide rails, such as sliding guide rails or rolling guide rails, in cooperation with sliders. The mechanical guide rails achieve positioning through rigid contact, but they have large frictional resistance and are prone to wear, resulting in a decrease in accuracy. After long-term operation, the positioning accuracy will decline. Dust, oil, etc. are more likely to cause guide rail jamming or accuracy decline. Especially in the case of high-speed movement or load changes, the insufficient stability of the slider leads to an increase in material positioning error and cannot meet the requirements of high-precision processing. Summary of the Invention

[0004] In order to reduce the wear of the slider and further improve the positioning accuracy of the material, this application provides an air-floating guide rail type high-precision seal paper positioning and transmission device.

[0005] The air-floating guide rail type high-precision seal paper positioning and transmission device provided by this application adopts the following technical solutions: An air-floating guide rail type high-precision seal paper positioning and transmission device includes a base, an air-floating guide rail module, a positioning module, a transmission module and a control system. The air-floating guide rail module includes a guide rail body, an air-floating slider and a gas supply system. The guide rail body is fixedly connected to the base. The air-floating slider is suspended on the guide rail body through a gas film. The gas supply system provides a stable air flow for the air-floating slider. Paper is placed on the air-floating slider. The positioning module can detect the positions of the air-floating slider and the paper. The transmission module can adjust the position of the air-floating slider. The control system receives and processes various data and regulates the operations among the air-floating guide rail module, the positioning module and the transmission module.

[0006] By adopting the above technical solution, the paper is placed on the air-bearing slider and moves along with the movement of the air-bearing slider. The air-bearing slider slides on the upper part of the guide rail body under the action of the transmission module, so as to drive and transport the paper. The positioning module detects the position of the air-bearing slider and transmits the position information to the control system. The control system drives the air-bearing slider to move to the set position through the transmission module. The air-bearing slider is suspended on the guide rail body through an air film, realizing frictionless movement, and significantly improving the accuracy and stability of positioning and transmission.

[0007] Preferably, the guide rail body includes a first slide base and two first guide rails. The two first guide rails are respectively fixedly connected to both sides of the base. Both ends of the first slide base are suspended and slide on the two first guide rails respectively, and the air-bearing slide base is suspended and slides on the first slide base.

[0008] By adopting the above technical solution, the air-bearing slide base can move in two directions of X and Y under the action of the first guide rail and the first slide base, expanding the moving range of the air-bearing slide base, so as to be able to position the air-bearing slider more accurately.

[0009] Preferably, the gas supply system includes an air pump and a throttle orifice belt. An air suction pipe and an air outlet are arranged on the air pump. The air outlet is communicated with the throttle orifice belt. One end of the throttle orifice belt far away from the air pump is connected to the first slider. A filtering device for filtering air is arranged on the air suction pipe.

[0010] By adopting the above technical solution, the filtering device can filter dust, moisture and other substances in the air, making the gas flowing in the air holes pure and dry, so as to reduce the blockage of the air holes by substances such as dust and oil stains.

[0011] Preferably, the filtering device includes an insertion pipe, a connecting socket and a filtering sleeve. The insertion pipe is inserted into the air suction pipe. The connecting socket is fixedly connected to one end of the insertion pipe. The connecting socket is sleeved and threadedly connected to the air suction pipe. The connecting socket is provided with a connecting groove. One end of the filtering sleeve is inserted and threadedly connected to the inner wall of the connecting groove. A first filter screen is arranged at one end of the filtering sleeve far away from the insertion pipe. A second filter screen is arranged inside the filtering sleeve. The filtering sleeve is communicated with the insertion pipe. A desiccant is arranged inside the insertion pipe.

[0012] By adopting the above technical solution, air enters the filtering sleeve through the first filter screen, enters the insertion pipe after the filtering effect is enhanced by the second filter screen, is dried by the desiccant and then enters the air pump through the air suction pipe. After the filtering device is used for a long time, the staff can replace the filtering device and the desiccant in the insertion pipe according to the dust blockage situation on the filter screen.

[0013] Preferably, there is a curved surface inside the filter sleeve, and the curved surface extends to connect with the second filter screen.

[0014] By adopting the above technical solution, the gas entering the filter sleeve through the first filter screen passes through the curved surface. Under the action of the curved surface, the gas flow rate gradually increases and passes through the second filter screen, so that the gas in the filter sleeve can pass through the second filter screen more quickly, thereby improving the filtration efficiency.

[0015] Preferably, a rubber pad is arranged on the upper surface of the air-floating slider, and the paper is placed on the rubber pad.

[0016] By adopting the above technical solution, the rubber pad has a large friction coefficient, which can increase the friction force between the paper and its surface and reduce the possibility of the paper moving.

[0017] Preferably, the positioning module includes two laser sensors and an adjusting mechanism. Detection plates are respectively and fixedly installed on both sides of the base. The two laser sensors are respectively installed on both side surfaces of the air-floating slider. One of the laser sensors irradiates the detection plate with laser, and the other laser detection sensor irradiates the side wall of the first slider with laser. The two laser sensors can respectively calculate the distances between the air-floating slider and the detection plate and the side wall of the first slider; the laser sensors transmit the data to the control system, and the control system adjusts the position of the air-floating slider through the transmission module. The adjusting mechanism can detect and adjust the position of the paper on the air-floating slider.

[0018] By adopting the above technical solution, the laser sensors can real-time monitor the distances from the boundary side walls, which is equivalent to the data on the X and Y axes of the coordinate. Before the device starts, the staff first set the position coordinates of the air-floating slider through the control system. Subsequently, when the air-floating slider moves, the laser sensors transmit the real-time data of the position where the air-floating is located to the control system. The control system compares the data with the set position coordinates and drives the air-floating slider to move to the set coordinates through the transmission module, so as to improve the detection accuracy and enhance the positioning accuracy of the paper.

[0019] Preferably, the adjusting mechanism includes a connecting plate and a visual detection device for detecting the position of the paper. The connecting plate is fixedly connected to the side wall of the air-floating slider. A connecting frame is fixedly connected to the connecting plate. The visual detection device is installed on the connecting frame. A connecting block is slidably arranged on the connecting plate, and an adjusting component for adjusting the paper is installed on the connecting block.

[0020] By adopting the above technical solution, the visual detection device can detect the position of the paper on the air-floating slider, detect whether the paper is tilted, offset in position, etc., and correct the position of the paper on the air-floating slider through the adjusting component to make its position accurate.

[0021] Preferably, the adjustment assembly includes an adjustment plate, a straight rod, and a hydraulic cylinder. A chute is formed in the connecting plate, and a first lead screw is rotatably connected in the chute. A first motor is fixedly installed on the side wall of the connecting block, and one end of the first lead screw is fixedly connected to the first motor. The connecting block is threadedly connected to the first lead screw. The straight rod is rotatably connected to the connecting block. A support block is fixedly connected to the connecting block. A turbine is fixedly sleeved on the straight rod. A micro motor is fixedly installed on the support block. A worm is fixedly connected to the rotating shaft of the micro motor. The worm meshes with the turbine. The adjustment plate slides on the straight rod. An arc-shaped block is fixedly connected to the support block. An arc-shaped groove is formed in the arc-shaped block, and a mounting block slides in the arc-shaped groove. The hydraulic cylinder is fixedly installed on the mounting block. The piston rod of the hydraulic cylinder is fixedly connected to the adjustment plate. A rotating block is rotatably arranged on the side of the adjustment plate facing the air-floating slider. A suction cup is installed on the rotating block, and the suction cup can adsorb the paper.

[0022] By adopting the above technical solution, when the paper needs to be adjusted, the control system starts the micro motor. Through the transmission of the turbine and worm, the straight rod drives the adjustment plate to rotate to above the paper. Then the hydraulic cylinder is started to drive the adjustment plate to move towards the paper until the suction cup adsorbs and fixes the paper. Subsequently, the control system comprehensively drives the paper to move to the precise position through the rotation of the adjustment plate, the linear sliding of the connecting block, and the rotation of the suction cup according to the deviation calculated from the visual detection data, thereby improving the high-precision positioning of the paper and facilitating subsequent printing and other operations.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The paper is placed on the air-floating slider and moves with the movement of the air-floating slider. The air-floating slider slides on the guide rail body under the action of the transmission module, thereby transporting the paper.

[0029] The following will Figures 1-4 further elaborate on the present application in detail.

[0030] The embodiment of the present application discloses a pneumatic guide rail type high-precision seal paper positioning and driving device, as Figure 1As shown in the figure, it includes a base 1, an air bearing guide module 2, a positioning module 3, a transmission module 44 and a control system. The air bearing guide module 2 includes a guide rail body 6, an air bearing slider 4 and a gas supply system 5. The guide rail body 6 is fixedly connected to the base 1. The air bearing slider 4 is suspended on the guide rail body 6 through a gas film. The gas supply system 5 provides a stable and clean air flow for the air bearing slider 4 through filtration. A rubber pad 21 is fixedly adhered to the surface of the air bearing slider 4. The rubber pad 21 can increase the friction between the paper and its surface and reduce the possibility of the paper moving. The paper is placed on the rubber pad 21. The positioning module 3 can detect the position of the air bearing slider 4 and adjust it. The transmission module 44 can adjust the position of the air bearing slider 4. The transmission module 44 can be a linear motor. The linear motor directly generates a linear motion through electromagnetic force to drive the first slide 7 to move on the first guide rail 8 and the air bearing slider 4 to move on the first slide 7, so as to control the position of the air bearing slide. The control system can receive and process various data and regulate the operation connection between the air bearing guide module 2, the positioning module 3 and the transmission module 44, so as to achieve frictionless movement, improve the stability of the air bearing slider 4 and improve the positioning accuracy. The air flow is clean and free of impurities after filtration, which can reduce the problem that the operation accuracy of the track is affected by the accumulation of dust, oil and other substances.

[0031] As Figure 1 shown, the guide rail body 6 includes a first slide 7 and two first guide rails 8. The two first guide rails 8 are arranged in parallel and are fixedly welded to the upper end surfaces on both sides of the base 1 respectively. The first slide 7 is perpendicular to the first guide rail 8, and its two ends are respectively suspended and slid on the two first guide rails 8. The air bearing slide is suspended on the first slide 7 and slides along the extension direction of the first slide 7. Under the guiding action of the first guide rail 8 and the first slide 7, the air bearing slide can move in two directions of X and Y, expanding the movement range of the air bearing slide, so as to more accurately control the position of the air bearing slider 4.

[0032] As Figure 1 and Figure 2As shown, the gas supply system 5 includes an air pump 9 for collecting and flowing air currents and a throttle orifice belt 10. The throttle orifice belt 10 is used to uniformly introduce compressed air into the air film gap between the guide rail and the slider to form a stable air floating support. The air pump 9 is provided with an air suction pipe 11 and an air outlet. The air suction pipe 11 is used to suck air currents from the air and convey them to the throttle orifice belt 10 through the air outlet. A filtering device 12 for filtering air is provided on the air suction pipe 11. The filtering device 12 includes an insertion pipe 13, a connecting socket 14, and a filtering sleeve 15. The connecting socket 14 is fixedly welded to one end of the insertion pipe 13 and integrally formed. The end of the insertion pipe 13 away from the connecting socket 14 is inserted into the air suction pipe 11. The connecting socket 14 is sleeved and threadedly connected to the air suction pipe 11. A connecting groove 16 is horizontally opened along the axis of the connecting socket 14. One end of the insertion pipe 13 is located in the connecting groove 16. One end of the filtering sleeve 15 is inserted and threadedly connected to the inner wall of the connecting groove 16 and aligned and communicated with the insertion pipe 13. A first filter screen 17 is provided on the surface of the end of the filtering sleeve 15 away from the insertion pipe 13. A second filter screen 18 is provided inside the filtering sleeve 15. The diameter of the first filter screen 17 is larger than that of the second filter screen 18, facilitating the inflow of air from the outside. A curved surface 20 with a gradually decreasing diameter is provided inside the filtering sleeve 15. The second filter screen 18 is connected to the midpoint of the curved surface 20. Under the action of the curved surface 20, the flow rate of the gas gradually increases when flowing from the first filter screen 17 to the second filter screen 18, accelerating the filtering speed of the gas inside the filtering sleeve 15.

[0033] As Figure 2 shown, a first partition plate 45 is rotatably provided at the end of the insertion pipe 13 away from the connecting socket 14. A second partition plate 46 is fixedly welded inside the insertion pipe 13. A plurality of ventilation holes are horizontally penetrated through the first partition plate 45 and the second partition plate 46. A desiccant 19, which can be activated carbon or the like, is placed between the first partition plate 45 and the second partition plate 46. Both the first partition plate 45 and the second partition plate 46 are cylindrical. A rotating rod is penetrated through the first partition plate 45 along its diameter. The two ends of the rotating rod rotate on the inner wall of the insertion pipe 13. The circumferential side wall of the first partition plate 45 is in interference fit with the inner wall of the insertion pipe 13. The gas is preliminarily filtered through the first filter screen 17, then strongly filtered through the second filter screen 18, and then the moisture and the like in the gas are adsorbed by the desiccant 19, thereby filtering dust, moisture, etc. in the air, making the gas flowing in the air holes pure and dry, and thus reducing the blockage of the air holes by substances such as dust and oil stains. The filtering sleeve 15 and the connecting socket 14 are both threadedly connected and can be disassembled according to the service time of the first filter screen 17, the second filter screen 18, and the desiccant 19 to clean the first filter screen 17 and the second filter screen 18 and replace the desiccant 19, etc.

[0034] As Figure 1 and Figure 3As shown in the figure, the positioning module 3 includes two laser sensors 22 and an adjustment mechanism 24. Detection plates 23 are fixedly installed at both ends of the base 1. The two laser sensors 22 are respectively installed on both side surfaces of the air-bearing slider 4 and are at the same height. The laser of one of the laser sensors 22 irradiates the detection plate 23, and the laser of the other laser detection sensor irradiates the side wall of the first slider. The two laser sensors 22 can respectively calculate the distances between the air-bearing slider 4 and the detection plate 23 and the side wall of the first slider. The laser sensors 22 transmit the data to the control system, so that the coordinates where the air-bearing slider 4 is located can be obtained. The control system adjusts the position of the air-bearing slider 4 through the transmission module 44, and can accurately position the air-bearing slider 4 at the set coordinates.

[0035] As Figure 3 and Figure 4 shown in the figure, the adjustment mechanism 24 can detect and adjust the position of the paper on the air-bearing slider 4. The adjustment mechanism 24 includes a connecting plate 25 and a vision detection device 26 for detecting the position of the paper. The connecting plate 25 is fixedly welded to the side wall of the air-bearing slider 4. A connecting frame 27 is fixedly welded to the connecting plate 25, and the vision detection device 26 is installed on the connecting frame 27. An adjustment assembly 29 for adjusting the paper is installed on the connecting block 28. The adjustment assembly 29 includes an adjustment plate 30, a straight rod 31 and a hydraulic cylinder 32. A chute 33 is formed in the connecting plate 25, and a first lead screw 34 is rotatably connected in the chute 33. A first motor 35 is fixedly installed on the side wall of the connecting block 28, and one end of the first lead screw 34 is fixedly connected to the first motor 35. The connecting block 28 is threadedly connected to the first lead screw 34. A support block 47 is fixedly welded to the top side wall of the connecting block 28. The support block 47 is slidably connected to the connecting plate 25. The straight rod 31 is rotatably connected to the upper end surface of the connecting block 28. A micro motor 38 is fixedly installed on the support block 47. A turbine 36 is fixedly sleeved on the bottom end of the straight rod 31. A worm 37 is fixedly welded to the rotating shaft of the micro motor 38, and the worm 37 meshes with the turbine 36. The control system can control the start, operation and rotation amplitude of the first motor 35, the micro motor 38 and the hydraulic cylinder 32. The adjustment plate 30 slides vertically along the straight rod 31. A guide groove 48 is formed in the side wall of the straight rod 31 along its length direction. A guide block 49 that slides in the guide groove 48 is arranged on the adjustment plate 30. An arc-shaped block 39 is fixedly welded to the upper end surface of the support block. An arc-shaped groove 42 is formed in the arc-shaped block 39. An installation block 43 slides in the arc-shaped groove 42. The hydraulic cylinder 32 is fixedly installed on the installation block 43. The piston rod of the hydraulic cylinder 32 is fixedly connected to the lower end surface of the adjustment plate 30. A rotating block 40 is rotatably arranged on the lower end surface of the adjustment plate 30. A suction cup 41 is connected to the rotating block. The suction cup 41 can adsorb the paper. The adjustment plate 30 is connected with an air pipe, and the air pipe is communicated with the suction cup 41.

[0036] As Figure 3 and Figure 4As shown in the figure, when the device is running, the laser sensor 22 can monitor the position of the air-bearing slider 4 in real time and make real-time adjustments through the transmission module 44, thereby improving the positioning accuracy of the air-bearing slider 4 and further enhancing the accuracy of paper positioning. After the air-bearing slider 4 is positioned, the vision detection device 26 can detect the position of the paper on the air-bearing slider 4 to check whether the paper is tilted, displaced, etc., and transmit the detected data to the control system. After the control system processes the data, it controls the first motor 35, the micro motor 38, the hydraulic cylinder 32, etc. Before the vision detects that the paper is displaced, the adjustment plate 30 is arranged along the extension direction of the connecting plate 25 under the drive of the micro motor 38, away from the air-bearing slider 4 to avoid affecting the vision detection. When the vision detects that the paper needs to be adjusted, the adjustment plate 30 moves in the direction close to the paper under the drive of the hydraulic cylinder 32, connects and fixes the paper through the suction cup 41. Subsequently, the first motor 35 drives the connecting block 28 through the lead screw to adjust the linear displacement of the paper. The micro motor 38 drives the straight rod 31 to rotate to adjust the rotation of the paper around the straight rod 31 as the axis to adjust the position. The rotating block 40 rotates to drive the suction cup 41 to rotate, so that the paper rotates around the suction cup 41, enabling the paper to be adjusted again at an angle, and the paper is precisely positioned through three aspects.

[0037] The implementation principle of the embodiment of this application is as follows: The paper is placed on the air-bearing slider 4 and moves with the movement of the air-bearing slider 4. The air-bearing slider 4 is suspended on the guide rail body 6 through an air film to achieve frictionless movement, reducing the error caused by friction after the device works for a long time. The air-bearing slider 4 slides on the guide rail body 6 under the action of the transmission module 44, thereby transporting the paper. The positioning module 3 detects the position of the air-bearing slider 4 and transmits the position information to the control system. The control system drives the air-bearing slider 4 to move to the set position through the transmission module 44. The positioning module 3 includes a vision detection device that can detect the position of the paper on the air-bearing slider 4, and adjusts the position of the paper through the adjustment assembly 29 to improve the positioning accuracy of the paper.

[0038] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
