Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly to an automated magnetic levitation multi-mover coupled flexible conveying line. Background Art

[0002] In modern industrial production, the material conveying line, as a key link in the production process, has an important impact on production efficiency and product quality. Traditional material conveying lines, such as belt conveying lines, chain conveying lines, etc., mainly rely on mechanical transmission to achieve material conveying. Such conveying lines usually adopt a single continuous conveying method, and all materials move at the same speed on the same conveying path, with poor flexibility and difficulty in meeting the diverse and personalized production needs. When the production task changes and it is necessary to adjust the conveying path or speed, it often requires large-scale transformation of the entire conveying line, which is time-consuming, laborious and costly.

[0003] In addition, due to the large friction between mechanical components in traditional conveying lines, wear is prone to occur during operation, which not only shortens the service life of the equipment, but also increases the maintenance cost and downtime, affecting the continuity and stability of production. At the same time, the automation level of traditional conveying lines is relatively low. In the processes of material positioning, control and conversion, manual intervention is often required, which not only increases the labor cost, but also is prone to human operation errors, resulting in production accidents and material damage.

[0004] With the development of industrial production towards intelligent and flexible directions, higher requirements are put forward for the efficiency, flexibility, reliability and automation level of material conveying lines. Existing conveying technologies are difficult to achieve precise and efficient material conveying in the face of complex production layouts and diverse technological processes, becoming a bottleneck restricting the improvement of production efficiency and the transformation and upgrading of production modes.

[0033] The embodiment of the present application discloses an automated magnetic levitation multi-mover coupled flexible conveyor line.

[0034] Please refer to Figures 1 to 8 , in an embodiment of the present application, an automated magnetic levitation multi-mover coupled flexible conveyor line includes two sets of stator guide rail devices 100 arranged in parallel. A plurality of mover levitation devices 200 are slidably connected to the stator guide rail devices 100. A levitation gas device 300 and a braking gas device 400 are connected to the stator guide rail devices 100 corresponding to the mover levitation devices 200. A magnetic force driving device 500 and a detection device 600 are installed between the stator guide rail devices 100 and the mover levitation devices 200. Anti-collision devices 700 are provided at both ends of the mover levitation devices 200. Ferry devices 800 are provided at both ends of the two sets of stator guide rail devices 100 corresponding to the mover levitation devices 200; the levitation gas device 300, the braking gas device 400, the magnetic force driving device 500, the detection device 600, the anti-collision device 700, and the ferry device 800 are all electrically connected to the control device 900.

[0035] During the working process, the control device 900 sends instructions to the suspension gas device 300 to generate positive-pressure gas, forming an air film between the stator guide device 100 and the mover suspension device 200, lifting the mover suspension device 200, and greatly reducing the friction between the two. At the same time, the magnetic drive device 500 generates a magnetic force under the control of the control device 900 to drive the corresponding mover suspension device 200 to slide smoothly along the stator guide device 100. The detection device 600 monitors the position and speed operation parameters of the mover suspension device 200 in real time and feeds the data back to the control device 900. The control device 900 adjusts the magnitude and direction of the magnetic force of the magnetic drive device 500 in a timely manner according to these data to ensure that each mover suspension device 200 operates according to a predetermined path and speed. When it is necessary to stop the mover suspension device 200, the control device 900 controls the braking gas device 400 to generate negative-pressure gas, adsorbing the mover suspension device 200 on the stator guide device 100 to make it stop quickly. The anti-collision devices 700 at both ends of the mover suspension device 200 play a safety protection role during the operation process to prevent collisions between the movers. The ferry devices 800 at both ends of the two groups of stator guide devices 100 can achieve a smooth transition and conversion of the mover suspension device 200 between different stator guide devices 100 under the control of the control device 900 to meet diverse conveying requirements.

[0036] Please also refer to Figures 1 to 8 , in a specific embodiment of the present application, the stator guide device 100 includes a mounting bracket 102, the mounting bracket 102 is fixedly installed on the mounting base 101, a guide rail 103 is fixedly installed on the mounting bracket 102, the mover suspension device 200 is installed on the guide rail 103, and uniformly distributed air guide holes 104 are opened along the length direction of the guide rail 103 towards the mover suspension device 200. An air guide channel 105 communicating with all the air guide holes 104 is opened inside the guide rail 103. A connecting pipe 106 communicating with the air guide channel 105 is fixedly and sealedly installed on the guide rail 103. One end of the connecting pipe 106 away from the mounting bracket 102 is connected to a tee pipe 107, and the other two ends of the tee pipe 107 are respectively connected to the suspension gas device 300 and the braking gas device 400.

[0037] During the working process, after the control device 900 issues an instruction to the suspension gas device 300, the gas enters the air guide channel 105 inside the guide rail 103 through the three-way pipe 107 and the connecting pipe 106, and then is discharged through the evenly distributed air guide holes 104, forming an air film between the guide rail 103 and the mover suspension device 200, lifting the mover suspension device 200, reducing the friction between the two, and enabling it to slide along the guide rail 103 under the action of the magnetic drive device 500. When the mover suspension device 200 needs to stop, the control device 900 controls the braking gas device 400 to work. The braking gas device 400 is connected to the guide rail 103 through the same path, but at this time, negative pressure gas is generated, and the mover suspension device 200 is adsorbed on the guide rail 103 through the air guide holes 104 to achieve braking. The detection device 600 monitors the operating state of the mover suspension device 200 in real time and feeds it back to the control device 900 to control the output of the gas and the operation of the magnetic drive device 500, ensuring the stable operation of the conveyor line.

[0038] Please also refer to Figures 1 to 8 , in a specific embodiment of the present application, the mover suspension device 200 includes a slider 201. The slider 201 is slidably connected to the guide rail 103. A chute 202 is provided on the side of the slider 201 close to the guide rail 103 corresponding to the cross-sectional shape of the guide rail 103. A gap for forming an air film is provided between the inner surface of the chute 202 and the outer surface of the guide rail 103. A connecting seat 203 is installed on the side of the slider 201 away from the guide rail 103. The magnetic drive device 500 and the detection device 600 are respectively installed on both side surfaces of the connecting seat 203. The anti-collision devices 700 are symmetrically installed on both end surfaces of the connecting seat 203.

[0039] During the working process, the suspension gas device 300 in the stator guide rail device 100 generates gas, forms an air film through the air guide channel 105 and the air guide holes 104, and lifts the slider 201 of the mover suspension device 200, enabling the slider 201 to float on the guide rail 103. At this time, the chute 202 on the slider 201 cooperates with the guide rail 103 to play a guiding role, ensuring that the slider 201 slides stably along the guide rail 103. The magnetic drive device 500 is installed on the side surface of the connecting seat 203 and generates a magnetic force under the regulation of the control device 900 to drive the mover suspension device 200 to move along the guide rail 103. The detection device 600 is also installed on the side surface of the connecting seat 203, monitors the operating parameters such as the position and speed of the mover suspension device 200 in real time, and feeds the data back to the control device 900 so that the control device 900 can timely adjust the magnitude and direction of the magnetic force of the magnetic drive device 500 to maintain the stable operation of the mover suspension device 200. When the mover suspension device 200 needs to stop, the braking gas device 400 generates negative pressure gas and adsorbs the slider 201 on the guide rail 103. The anti-collision devices 700 on both end surfaces of the connecting seat 203 provide real-time protection during the operation process to prevent the mover suspension device 200 from colliding with other objects and ensure the safety of the conveying.

[0040] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the suspension gas device 300 includes a vacuum pump 301. The output end of the vacuum pump 301 is fixedly and sealingly connected to an output pipe 302. The end of the output pipe 302 away from the vacuum pump 301 is fixedly and sealingly connected to a pressure stabilizing tank 303. A first electric control valve 304 is fixedly and sealingly connected to the pressure stabilizing tank 303. A positive pressure pipe 305 is sealingly connected to the first electric control valve 304. The positive pressure pipe 305 is sealingly connected to the three-way pipe 107.

[0041] During the working process, when the automated magnetic levitation multi-mover coupled flexible conveyor line starts to operate, the control device 900 sends a start command to the vacuum pump 301 in the suspension gas device 300. The vacuum pump 301 starts to work, extracts air and transmits the gas to the pressure stabilizing tank 303 through the output pipe 302. The pressure stabilizing tank 303 stabilizes the gas pressure to keep the gas pressure stable and avoid affecting the suspension effect due to pressure fluctuations. Subsequently, the control device 900 controls the first electric control valve 304 to open. The pressurized positive-pressure gas enters the three-way pipe 107 through the positive pressure pipe 305, then flows into the connecting pipe 106 and the air guide channel 105 of the stator guide device 100 in sequence, and finally discharges from the air guide hole 104, forming a uniform and stable air film between the guide rail 103 and the mover suspension device 200, lifting the mover suspension device 200, enabling it to slide along the guide rail 103 with low friction and stability under the action of the magnetic drive device 500.

[0042] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the braking gas device 400 includes an input pipe 401. The input pipe 401 is fixedly and sealingly connected to the input end of the vacuum pump 301. The end of the input pipe 401 away from the vacuum pump 301 is fixedly and sealingly connected to a vacuum tank 402. A second electric control valve 403 is fixedly and sealingly connected to the vacuum tank 402. A pressure relief valve 404 is fixedly and sealingly connected to the pressure stabilizing tank 303. A vacuum breaker 405 is fixedly and sealingly connected to the vacuum tank 402. A negative pressure pipe 406 is sealingly connected to the second electric control valve 403. The negative pressure pipe 406 is sealingly connected to the three-way pipe 107.

[0043] During the working process, when it is necessary to brake the mover suspension device 200, the control device 900 issues an instruction to the braking gas device 400 to control the opening of the second electronic control valve 403. At this time, the vacuum pump 301 extracts gas from the vacuum tank 402 through the input pipe 401, creating a negative pressure environment inside the vacuum tank 402. The negative pressure gas enters the three-way pipe 107 through the negative pressure pipe 406, then flows into the connecting pipe 106 and the air guide channel 105 of the stator guide device 100, and is discharged from the air guide hole 104. The adsorption force generated by the negative pressure gas firmly adsorbs the mover suspension device 200 on the guide rail 103, causing it to stop moving quickly. After the braking is completed, the control device 900 controls the opening of the vacuum breaking valve 405, and external air enters the vacuum tank 402 to destroy its negative pressure state, facilitating subsequent operations. At the same time, the control pressure relief valve 404 is opened to release the excess gas in the pressure stabilizing tank 303, preparing for the next suspension gas output. During the whole process, the vacuum pump 301 is shared with the suspension gas device 300, and the gas function switching between suspension and braking is realized through different pipelines and valve controls.

[0044] Please also refer to Figures 1 to 8 , in a specific embodiment of the present application, the magnetic drive device 500 includes a magnetic body 501. One side of the connecting seat 203 is fixedly installed with a first mounting plate 502, and the magnetic body 501 is fixed on the first mounting plate 502. A number of equally spaced first electromagnetic members 503 are fixedly installed on one side surface of the mounting bracket 102. The first electromagnetic members 503 are arranged along the length direction of the guide rail 103, and the first electromagnetic members 503 are arranged corresponding to the magnetic body 501.

[0045] During the working process, when the magnetic drive device 500 operates, the control device 900 transmits a current signal to the first electromagnetic member 503. After the first electromagnetic member 503 is energized, it generates a magnetic field, generating an electromagnetic interaction force with the magnetic body 501 fixed on the first mounting plate 502 of the connecting seat 203. When the control device 900 changes the magnitude and direction of the current of the first electromagnetic member 503, the intensity and direction of the generated magnetic field also change accordingly, thereby adjusting the magnitude and direction of the electromagnetic force between the magnetic body 501. Under the action of the electromagnetic force, the magnetic body 501 of the mover suspension device 200 drives the entire mover suspension device 200 to move along the guide rail 103. At the same time, the detection device 600 real-time monitors parameters such as the position and speed of the mover suspension device 200 and feeds them back to the control device 900. The control device 900 adjusts the current of the first electromagnetic member 503 in a timely manner according to the feedback data, realizing precise control of the operating state of the mover suspension device 200, and enabling it to operate stably according to the predetermined path and speed.

[0046] Please also refer to Figures 1 to 8, in a specific embodiment of the present application, the detection device 600 includes a grating scale 601. A second mounting plate 602 is fixedly installed on one side of the connecting seat 203, and the grating scale 601 is fixedly installed on the second mounting plate 602. A number of equally spaced first grating detectors 603 are fixedly installed on one side surface of the mounting bracket 102. The first grating detectors 603 are electrically connected to the control device 900. The first grating detectors 603 are arranged along the length direction of the guide rail 103 and are correspondingly arranged with the grating scale 601.

[0047] During the working process, when the detection device 600 is running, the grating scale 601 fixed on the second mounting plate 602 of the connecting seat 203 moves along the guide rail 103 together with the mover suspension device 200. The first grating detectors 603 equally spaced along the length direction of the guide rail 103 on the mounting bracket 102 continuously emit and receive optical signals. When the grating scale 601 passes through the first grating detectors 603, it will cause a change in the occlusion or transmission of the optical signal. The first grating detectors 603 convert this change in the optical signal into an electrical signal and transmit it to the control device 900. The control device 900 calculates the operating parameters such as the real-time position and moving speed of the mover suspension device 200 by analyzing the change frequency and quantity of the received electrical signal. According to these parameters, the control device 900 can timely adjust the working state of the magnetic drive device 500, such as changing the magnitude and direction of the current of the first electromagnetic member 503, so as to achieve precise control of the operating state of the mover suspension device 200 and ensure its stable operation along the predetermined path and speed.

[0048] Please refer to Figures 1 to 8 , in a specific embodiment of the present application, the anti-collision device 700 includes anti-collision blocks 701 fixedly installed at both ends of the connecting seat 203. An exhaust groove 702 penetrating the sliding groove 202 is formed on the slider 201. A first exhaust passage 703 communicating with the exhaust groove 702 is formed inside the guide rail 103. A second exhaust passage 704 hermetically communicating with the first exhaust passage 703 is formed on the connecting seat 203. An exhaust hole 705 communicating with the second exhaust passage 704 is formed on the anti-collision block 701 along the length direction of the guide rail 103.

[0049] During the working process, when the mover suspension device 200 is running on the guide rail 103, the positive pressure gas generated by the suspension gas device 300 will enter the first exhaust passage 703 through the air guide passage 105 of the guide rail 103, then pass through the exhaust groove 702 of the slider 201 and the second exhaust passage 704 of the connecting seat 203, and finally be discharged from the exhaust hole 705 of the anti-collision block 701. If the distance between two adjacent mover suspension devices 200 is too small, the discharged gas will cancel each other out between the two anti-collision blocks 701, thereby buffering the collision energy and reducing the impact force of direct contact.

[0050] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the number of exhaust holes 705 is two. Two exhaust holes 705 on two anti-collision blocks 701 that are adjacent to each other and close to each other on two adjacent connecting seats 203 are coaxially aligned. A sealing plug 706 is fixedly and sealingly installed inside one exhaust hole 705 on the same anti-collision block 701. An active plug 707 is elastically connected to the sealing plug 706. A pressure sensor 708 is arranged between the active plug 707 and the sealing plug 706. The exhaust hole 705 with the sealing plug 706 installed in two adjacent anti-collision blocks 701 is coaxially aligned with the other exhaust hole 705 without the sealing plug 706 installed.

[0051] During the working process, when two adjacent mover suspension devices 200 approach each other, the coaxially aligned exhaust holes 705 form an air flow channel. The positive-pressure gas discharged from the exhaust hole 705 without the sealing plug 706 rushes into the exhaust hole 705 with the sealing plug 706 installed. The active plug 707 compresses the spring and moves towards the sealing plug 706 under the action of the gas pressure. At this time, the pressure sensor 708 monitors the pressure change between the active plug 707 and the sealing plug 706 in real time and transmits the signal to the control device 900. When the pressure value exceeds the preset threshold, the control device 900 determines that there is a collision risk, immediately controls the braking gas device 400 to start, and at the same time adjusts the magnetic drive device 500 to reduce the mover speed or change the running direction to achieve multiple protections.

[0052] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the ferry device 800 includes a ferry slide rail 801. A ferry slider 802 is slidably connected to the ferry slide rail 801. A driving member is installed between the ferry slide rail 801 and the ferry slider 802. A ferry support 803 is installed on the ferry slider 802. A ferry guide rail 804 corresponding to the mover suspension device 200 is installed on the ferry support 803. The ferry guide rail 804 is flush with the stator guide rail device 100. A second electromagnetic member 805 corresponding to the magnetic drive device 500 is installed on the ferry support 803. A second grating detector 806 corresponding to the detection device 600 is installed on the ferry support 803.

[0053] During the working process, the driving member provides power for the sliding of the ferry slider 802 on the ferry slide rail 801, enabling it to move along the slide rail. When it is necessary to transfer the mover suspension device 200 from the corresponding stator guide rail device 100 to the ferry device 800, the ferry slider 802 moves to a position flush with the corresponding stator guide rail device 100 under the action of the driving member, aligning the ferry guide rail 804 with the guide rail 103. At the same time, the second electromagnetic member 805 and the second grating detector 806 are respectively arranged corresponding to the magnetic force driving device 500 and the detection device 600 to realize the magnetic force driving and position detection functions of the mover suspension device 200. During the transfer process, the magnetic force driving device 500 interacts with the second electromagnetic member 805 to provide a driving force for the mover suspension device 200, enabling it to move on the ferry guide rail 804. The detection device 600 and the second grating detector 806 then continuously monitor the position information of the mover suspension device 200 to ensure that it moves accurately on the guide rail and feedback the position signal to the control device 900 for precise control and adjustment.

[0054] It can be understood that in the specific implementation manner of the present application, the driving member can be a power device such as a motor or a cylinder, and the power is transmitted to the ferry slider 802 through a transmission mechanism (such as a lead screw, a chain, etc.). The driving member can also directly adopt a linear motor to directly transmit the power to the ferry slider 802, thereby achieving precise position control.

[0055] Please refer to Figures 1 to 8 as well. In a specific implementation manner of the present application, a limit seat 807 is installed on the ferry bracket 803 away from the stator guide rail device 100, and a buffer pad is installed on the limit seat 807 corresponding to the mover suspension device 200.

[0056] During the working process, when the mover suspension device 200 moves on the ferry guide rail 804, the limit seat 807 plays a role in restricting its moving range. When the mover suspension device 200 approaches the limit seat 807, the buffer pad first contacts the mover suspension device 200. The buffer pad is usually made of an elastic material such as rubber or polyurethane, and it can deform when the two come into contact, absorbing and buffering the kinetic energy of the mover suspension device 200, thereby slowing down its speed and finally stopping the mover suspension device 200 at the limit seat 807 to prevent it from exceeding the predetermined position range due to inertia, causing damage to the equipment or triggering a safety accident.

[0057] Please refer to Figures 1 to 8 as well. In a specific implementation manner of the present application, position detectors 808 are installed on the ferry slide rail 801 corresponding to the two groups of stator guide rail devices 100, and position detection plates 809 are fixedly installed on the ferry slider 802 corresponding to the position detectors 808.

[0058] During the working process, when the ferry slider 802 moves on the ferry slide rail 801, the position detection plate 809 moves synchronously with the slider. When the position detection plate 809 passes by the position detector 808, the position detector 808 will detect the position information of the position detection plate 809 and convert this information into an electrical signal and send it to the control device 900. Based on the received signal, the control device 900 can accurately determine whether the ferry slider 802 has reached the predetermined position aligned with the stator guide rail device 100. When it is detected that the position detection plate 809 is aligned with the position detector 808 of the corresponding stator guide rail device 100, the control device 900 will control the driving member to stop operating, so that the ferry slider 802 accurately stops at the target position, ensuring that the ferry guide rail 804 is flush with the guide rail 103 of the stator guide rail device 100, providing guarantee for the smooth transfer of the mover suspension device 200.

[0059] Please also refer to Figures 1 to 8 , in a specific embodiment of the present application, the control device 900 includes a controller 901, and the controller 901 is electrically connected to the suspension gas device 300, the braking gas device 400, the magnetic drive device 500, the detection device 600, the anti-collision device 700, and the ferry device 800. The controller 901 is electrically connected to a control panel 902 and a display 903.

[0060] During the working process, the controller 901 serves as the core of the entire system, receives signals from various devices, and processes and analyzes these signals according to preset programs and logics. Based on the received signals, the controller 901 sends control instructions to various devices. The control panel 902 is used for operators to input various control parameters and instructions, such as setting the running speed, running path, docking position, etc. of the mover suspension device 200. These information will be transmitted to the controller 901 so that the controller 901 can control the system according to the requirements of the operators. The display 903 is used to display various operating status information of the system, such as the current position, speed of the mover suspension device 200, the working status of each device, and possible fault information, etc., facilitating the operators to understand the system operation situation in real time, discover problems in time and handle them.

[0061] The implementation principle of an automated magnetic levitation multi-mover coupled flexible conveyor line in an embodiment of the present application is: The operator inputs control parameters and instructions through the control panel 902, and the display 903 displays the system operation status in real time. The control device 900 coordinates and controls the operation of the entire conveyor line according to the preset program and the received signals. The suspension gas device 300 generates positive pressure gas under the control instruction, and forms an air film through the air guide structure of the stator guide device 100 to support the rotor suspension device 200. At the same time, the magnetic drive device 500 generates electromagnetic force to drive the rotor to move along the guide rail; the detection device 600 monitors the position and speed of the rotor in real time and feeds back data, and the control device 900 dynamically adjusts the magnitude and direction of the magnetic force accordingly to ensure that the rotor runs along the predetermined path. During braking, the braking gas device 400 generates negative pressure gas to adsorb the rotor to achieve precise docking, and the anti-collision device 700 avoids collision accidents through a dual mechanism of air buffer and pressure sensing warning. When it is necessary to switch the conveying path, the driving part of the ferry device 800 drives the ferry slider to move to the designated position, and cooperates with the rotor through the second electromagnetic part 805 and the second grating detector 806 to achieve a smooth transfer of the rotor between different guide rails. Each device operates in coordination under the unified control of the control device 900, so as to realize diversified and flexible material conveying, improve the conveying efficiency and the intelligent level of production, and meet the requirements of modern industrial production.

[0062] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
