[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] In the related technologies, the magnetic levitation conveying system has replaced the traditional conveying systems such as belt conveying and chain drive in some fields due to its advantages of high flexibility, high speed and high precision. The magnetic levitation conveying system includes a stator and a mover. The stator is spliced ​​in sequence along the conveying direction to form a conveying line body, and the mover moves on the conveying line body.

[0040] In the conveying system, the mover moves forward under the action of magnetic force; when braking is required, the specific coil is energized, and the mover obtains reverse acceleration, thereby achieving rapid braking. However, when the conveying system is powered off and shut down, the coil cannot be energized to achieve mover braking, which will cause the mover to be unable to stop quickly, making it easy for the mover to collide or derail.

[0041] Based on this, the embodiment of the present application proposes a linear transport system 1, which can realize rapid braking of the moving module 30 when the conveying system is powered off. Figure 1 The linear transport system 1 includes a base 10 , a stator module 20 , a mover module 30 and a brake module 40 .

[0042] The stator module 20 includes a stator body 21, a coil assembly 22 and a guide rail 23. The stator body 21 and the guide rail 23 are both mounted on the base 10. The coil assembly 22 is mounted on the stator body 21 and arranged in parallel with the guide rail 23. In some embodiments, the stator body 21 may include a straight stator unit and a curved stator unit, which are connected in sequence to arrange the stator body 21 into a closed moving track.

[0043] The stator body 21 can be made of rigid metal, such as aluminum or steel, so that the production cost can be reduced while ensuring that the stator body 21 has a high structural strength. The coil assembly 22 and the stator body 21 can be connected by at least one of welding, gluing, screwing, and plugging, which is not specifically limited in the embodiment of the present application.

[0044] The mover module 30 includes a mover body 31 and a limiting structure 32, and the limiting structure 32 is relatively fixed to the mover body 31. The mover body 31 includes a mover bracket 311 and a first permanent magnet array 312, the first permanent magnet array 312 is connected to the mover bracket 311, and is magnetically coupled with the coil assembly 22, and the mover bracket 311 is slidably matched with the guide rail 23. When the coil assembly 22 is powered, the magnetic field generated by the first permanent magnet array 312 and the magnetic field generated by the coil assembly 22 can interact to push the mover body 31 to produce translational motion, so that the mover module 30 can move along the extension direction of the coil assembly 22.

[0045] The connection method between the first permanent magnet array 312 and the mover bracket 311 includes but is not limited to screw fixation, clamp fixation, hot melt or injection molding fixation, press-in fixation, glue fixation, and double-sided tape fixation. It can be understood that the mover module 30 can be set to one or more, and the embodiment of the present application does not limit the specific number of the mover modules 30.

[0046] The brake module 40 includes a moving part 41, a reset part and a brake part 42. Figure 2 and Figure 3 , the moving part 41 is magnetically coupled with the coil assembly 22, and can be moved within the range of the limiting structure 32 by the magnetic force of the coil assembly 22. The moving part 41 is provided with a first matching portion 411, and the brake part 42 includes a brake part 422 and a second matching portion 421 connected to the brake part 422, and the brake part 422 is slidably matched with the limiting structure 32. In some structural forms, the moving part 41 includes a mounting seat 412 and a second permanent magnet array 413, and the second permanent magnet array 413 is connected to the mounting seat 412 and is magnetically coupled with the coil assembly 22. The mounting seat 412 is provided with the above-mentioned first matching portion 411. The connection method of the second permanent magnet array 413 and the mounting seat 412 includes but is not limited to screw fixation, clamp fixation, hot melt or injection molding glue fixation, press-in fixation, glue fixation, and double-sided adhesive fixation. Among them, the moving part 41 will move in the first direction under the magnetic force drive of the coil assembly 22. The reset member is used to drive the moving part 41 to move in the second direction. The first direction and the second direction are opposite.

[0047] Apply the technical solution of the embodiment of the present application: When the coil assembly 22 is not working, refer to Figure 4 and Figure 5, the braking portion 422 of the braking member 42 will be mechanically fixed to the guide rail 23. When the coil assembly 22 is working, both the moving member 41 and the movable body 31 will be subjected to magnetic force. The braking member 42 slides with the limiting structure 32, and the braking member 42 and the limiting structure 32 are relatively fixed in the extension direction of the coil assembly 22. At this time, the movable body 31 will be relatively fixed to the guide rail 23. Driven by the magnetic force of the coil assembly 22, the moving member 41 will first move in the first direction. During the movement of the moving member 41 in the first direction, the first matching portion 411 of the moving member 41 will also move in the first direction, and the second matching portion 421 of the braking member 42 slides against the first matching portion 411, so that the braking portion 422 can be driven to move in the direction of the guide rail 23 away from the moving member 411. After the braking portion 422 moves away from the guide rail 23, the movable module 30 can be released. Please refer to Figure 2 and Figure 3 , the mover module 30 can move in the first direction under the magnetic force of the coil assembly 22. When the coil assembly 22 is powered off, the magnetic force on the mover body 31 and the moving part 41 disappears, and the reset part drives the moving part 41 to move in the second direction. During the movement of the moving part 41 in the second direction, the first matching part 411 of the moving part 41 moves in the second direction at the same time, and the second matching part 421 of the brake part 42 slides against the first matching part 411, so that the brake part 422 can be driven to move toward the approaching guide rail 23 as the first matching part 411 moves, and the brake part 422 can be mechanically fixed to the guide rail 23.

[0048] Based on the linear transport system 1 of the embodiment of the present application, when the coil assembly 22 is powered on, the moving part 41 and the movable module 30 can be driven to move in the first direction at the same time. At this time, the moving part 41 will make the reset part have reset potential energy. When the coil assembly 22 is powered off, the reset part will drive the moving part 41 to move in the second direction. During the movement of the moving part 41 in the second direction, the first matching part 411 of the moving part 41 will move in the second direction at the same time, and the second matching part 421 of the brake part 42 slides against the first matching part 411, so that the brake part 422 can be driven to move toward the direction of the approaching guide rail 23 with the movement of the first matching part 411, so that the brake part 422 is mechanically fixed to the guide rail 23, so that the movable module 30 can be quickly braked, the collision or derailment of the movable module 30 can be prevented, and the safety of the linear transport system can be improved. The present application drives the moving part 41 to move in the first direction through the coil assembly 22 so that the reset part has reset potential energy. In this way, the original structure and power source of the conveying system can be used to realize the driving and resetting functions of the moving part 41 without the need for additional driving devices, thereby improving the overall efficiency and economy of the system. Moreover, the mechanical braking method adopted in the present application can reduce the dependence on power supply and increase the stability and reliability of the system. The brake module 40 of the present application moves independently, and the braking distance of the present application can be controlled by controlling the moving distance of the brake part 42 pushed by the reset part. In this way, the braking effect of the mover can be flexibly adjusted according to the specific situation.

[0049] For example, when the mover module 30 is running at a high speed, or when the mover module 30 transports a large amount or heavy goods, it is easily affected by the inertia effect. In these cases, a longer braking distance is required to enable the mover module 30 to stop safely. The present application can ensure that the power module has enough time to decelerate by extending the braking distance to avoid the rigid collision between the brake module 40 and the guide rail 23. When the mover module 30 is transported at a low speed, or when the number of mover modules 30 is relatively large and the arrangement is relatively dense, a shorter braking distance is required to stop the mover module 30 quickly. The present application can stop the power module quickly by shortening the braking distance.

[0050] It is further explained that the moving part 41 of the present application reciprocates in the first direction and the second direction, and the second direction and the second direction and the running direction of the mover module 30 are arranged in parallel. In this way, the braking distance arrangement direction is designed to be consistent with the running direction of the mover module 30, which can improve the flexibility of designing the braking distance. In detail, the movement distance of the mover module 30 is relatively long, so the length of the braking distance can be flexibly designed. If the braking distance is arranged in the up and down directions, when the braking distance needs to be designed to be longer, more vertical space will be occupied, and the influence of gravity on the brake needs to be considered. Compared with the form of setting the braking distance in the up and down directions, the present application can effectively utilize space and accurately control the length of the braking distance to meet the requirements under different working conditions.

[0051] There can be various assembly relationships between the brake module 40 and the mover module 30, which will be introduced in the following of this application.

[0052] In some of the embodiments, in the extension direction of the coil assembly 22, the moving part 41 is located on one side of the mover body 31. In this way, by adjusting the distance between the moving part 41 and the mover body 31 during the movement, the length of the braking distance can be adjusted. It should be noted that, based on the running direction of the mover module 30, the moving part 41 can be located on the front side of the mover body 31 or on the rear side of the mover body 31, and can be adaptively adjusted according to specific application needs and design requirements.

[0053] Specifically, when the moving part 41 is located at the front side of the mover body 31, under the magnetic drive of the coil assembly 22, the moving part 41 and the mover body 31 both move in the first direction, and at this time there will be a first spacing between the moving part 41 and the mover body 31, and under the drive of the reset member, the moving part 41 will move in the second direction, and at this time the moving part 41 will move in the direction close to the mover body 31. When the moving part 41 is located at the rear side of the mover body 31, during the process of the moving part 41 and the mover body 31 running in the first direction under the magnetic drive of the coil assembly 22, the moving part 41 and the mover body 31 have a second spacing, and under the drive of the reset member, the moving part 41 will move in the second direction, and at this time the moving part 41 will move away from the mover body 31. It can be understood that the first spacing is greater than the second spacing.

[0054] The limiting structure 32 can limit the range of the moving part 41, so that the distance between the moving part 41 and the mover body 31 during the movement can be adjusted by the limiting structure 32. In order to improve the stability of the limiting structure 32 on the moving part 41, please refer to Figure 8The limiting structure 32 includes a guide rod 321 and a limiting block 322. The limiting block 322 is connected to one side of the guide rod 321. The side of the guide rod 321 away from the limiting block 322 is connected to the mover body 31. The moving part 41 is sleeved on the guide rod 321. The limiting block 322 and the guide rod 321 jointly define a range for limiting the movement stroke of the moving part 41. Specifically, the moving part 41 reciprocates along the axial direction of the guide rod 321 to improve the stability of the moving part 41 and the mover body 31 during the relative movement. When the moving part 41 slides on the guide rod 321, the outer wall surface of the mover body 31 and the inner wall surface of the limiting block 322 will limit the running stroke of the moving part 41. In this way, the moving part 41 is prevented from detaching from the mover module 30 during the movement, which can ensure the stability of the relative movement of the moving part 41 and the mover body 31, thereby improving the stability of the brake module 40 in stopping the mover module 30.

[0055] Furthermore, the number of the guide rods 321 is two, and the mounting seat 412 includes a first assembly portion 4121 and a second assembly portion 4122, which are arranged at intervals and are both provided with a first matching portion 411, and the first assembly portion 4121 and the second assembly portion 4122 are respectively sleeved on one guide rod 321. In this way, the stability of the relative movement between the moving member 41 and the mover body 31 can be further improved, and the stability of the operation of the brake member 42 can also be improved.

[0056] In order to facilitate the adjustment of the braking distance, in some embodiments, the guide rod 321 and the movable bracket 311 can be threadedly connected, and the different positions of the guide rod 321 can be adjusted by threading to be relatively fixed to the movable bracket 311, so that the operating range of the moving part 41 can be adjusted, and then the braking distance of the brake module 40 can be adjusted.

[0057] It is further explained that the braking distance of the brake module 40 is associated with the distance of the sliding fit of the first matching part 411 and the second matching part 421. The first matching part 411 and the second matching part 421 have a certain inclination angle. When the inclination angle is large, the first matching part 411 and the second matching part 421 slide against each other, and the speed at which the brake member 42 moves in the direction of approaching and moving away from the guide rail 23 is faster, so that a smaller braking distance can be achieved. In this process, the movement stroke required by the moving part 41 will be smaller. When the inclination angle is small, the first matching part 411 and the second matching part 421 slide against each other, and the speed at which the brake member 42 moves in the direction of approaching and moving away from the guide rail 23 is slower, so that a larger braking distance can be achieved. In this process, the movement stroke required by the moving part 41 will be larger. In this application, adjusting the different positions of the guide rod 321 to be relatively fixed with the mover bracket 311 is to adapt to the movement stroke of the moving part 41, and indirectly adjusting the braking distance of the brake module 40 is not directly adjusting the braking distance of the brake module 40.

[0058] In some of these embodiments, please refer again to Figure 8 , a limiting hole 323 is provided on the limiting block 322, and the braking part 422 may be rod-shaped, and the braking part 422 may be slidably arranged in the limiting hole 323, so as to improve the stability of the braking part 422 approaching or away from the guide rail 23. Considering the smoothness of the braking part 422 sliding in the limiting hole 323, a bearing may be installed on the hole wall of the limiting hole 323, so as to reduce the friction between the braking part 422 and the limiting hole 323. Of course, in other embodiments, the braking part 422 may be block-shaped, and the limiting block 322 may be provided with at least two limiting surfaces, and the movement direction of the braking part 422 may be limited by the limiting surfaces, so as to improve the stability of the braking part 422 approaching or away from the guide rail 23.

[0059] In some other embodiments, an avoidance groove can be provided on the mover bracket 311, and the moving part 41 is embedded in the avoidance groove and slidably arranged in the avoidance groove, and the opposite sides of the avoidance groove define the range of travel that limits the movement of the moving part 41, so that the avoidance groove can form part of the limiting structure 32. In this embodiment, the brake module 40 can be installed in a hidden manner to reduce the possibility of the moving part 41 being interfered with by the outside, making the system more stable and reliable, extending the service life of the equipment, and also effectively utilizing the space. The above-mentioned limiting hole 323 can be opened on the wall of the mover bracket 311, and the limiting hole 323 connects the avoidance groove and the external space. Here, the present application does not limit the specific installation method of the brake module 40 and the mover module 30 and the specific form of the limiting structure 32.

[0060] The reset member of the present application can have various forms and installation positions. In order to improve the stability of the reset member driving the moving member 41 to move, please refer to Figure 5 The reset member can be a spring 43, which can play the role of buffering, shock absorption, vibration reduction, etc., to protect the stability and safety of the system. In addition, the spring 43 has a simple structure and is easy to manufacture and install.

[0061] In some connection modes, the spring 43 can be a compression spring, which is sleeved on the guide rod 321 and abuts against the moving part 41 and the limit block 322 on opposite sides. When the moving part 41 moves in the first direction under the drive of the magnetic force, the magnetic force will be greater than the elastic force of the spring 43, and the compression spring will be compressed. When the magnetic force disappears, the compression spring releases elastic potential energy to move the moving part 41 in the second direction. Of course, after the moving part 41 moves into place, the spring 43 can still retain potential energy, that is, during the reciprocating motion of the moving part 41, the compression spring is always compressed, thereby improving the stability of the operation of the moving part 41 driven by the reset member.

[0062] The spring 43 can also be a tension spring, which is sleeved on the guide rod 321 and connected to the mover bracket 311 and the moving part 41 on opposite sides. When the moving part 41 moves in the first direction driven by the magnetic force, the magnetic force will be greater than the elastic force of the tension spring, and the tension spring will be stretched. When the magnetic force disappears, the tension spring releases elastic potential energy to move the moving part 41 in the second direction. Of course, after the moving part 41 moves into place, the tension spring can still retain potential energy, that is, during the reciprocating motion of the moving part 41, the tension spring is always stretched, thereby improving the stability of the reset member driving the moving part 41 to operate.

[0063] Of course, in some other embodiments, the reset member may also include a first magnetic member and a second magnetic member. When the first magnetic member is installed on the moving member 41 and the second magnetic member is installed on the limit block 322, the first magnetic member and the second magnetic member may be magnets of the same sex, and the reset function is achieved through the magnetic force of like sex repelling each other. When the first magnetic member is installed on the moving member 41 and the second magnetic member is installed on the mover bracket 311, the first magnetic member and the second magnetic member may be magnets of opposite sex, and the reset function is achieved through the magnetic force of opposite sex attracting each other. Here, the present application does not make specific restrictions on the form and installation position of the reset member.

[0064] In order to improve the stability of the sliding abutment between the first matching portion 411 and the second matching portion 421, please refer to Figures 2 to 7 In the embodiment of the present application, the first matching portion 411 is a guide groove, and the second matching portion 421 is a guide rod, and the guide rod and the guide groove are slidably matched. The sliding match between the guide groove and the guide rod can effectively enhance the stability between the two, prevent the brake member 42 from deflecting or swinging during the movement, and improve the accuracy and stability of the system. Of course, in some other embodiments, the first matching portion 411 and the second matching portion 421 can be wedge-shaped surfaces, and relative sliding is achieved through the matching and abutment of the wedge-shaped surfaces. Here, the present application does not limit the specific form of the first matching portion 411 and the second matching portion 421.

[0065] The mechanical fixation of the brake part 422 and the guide rail 23 can be in various forms. In some of the embodiments, please refer to Figure 1 The guide rail 23 is provided with a plurality of brake holes 24 arranged at intervals. It can be understood that the plurality of brake holes 24 are arranged at a certain interval, but such intervals are not necessarily uniform and can be adjusted according to the braking requirements. During the movement of the moving member 41 along the second direction, the brake portion 422 can be inserted into the brake hole 24. Please refer to Figures 5 to 7, the braking part 422 is inserted into the braking hole 24, so as to be relatively fixed with the guide rail 23, thereby braking the movable module 30. If the coil assembly 22 is energized, and the moving part 41 moves in the first direction under the magnetic drive of the coil assembly 22, the braking part 422 will be separated from the braking hole 24 as the moving part 41 moves, thereby releasing the movable module 30, so that the movable module 30 can move in the first direction under the magnetic drive of the coil assembly 22. In this process, the reset part will have reset potential energy. When power is not applied to the coil assembly 22, the reset part will drive the movable part 41 to move in the second direction, thereby driving the braking part 422 to approach the guide rail 23 to be inserted into the braking hole 24 again. During the movement of the movable part 41, the braking part 42 will be inserted into the nearest braking hole 24 in the first direction to achieve mechanical fixation with the guide rail 23.

[0066] During the process of mechanically fixing the brake member 42 and the guide rail 23, when the brake portion 422 is inserted into the brake hole 24, the brake can be applied immediately, ensuring the timeliness and accuracy of the brake. If the brake portion 422 is not inserted into the brake hole 24 but abuts against the guide rail 23, the system will apply the brake at the next brake hole 24. By arranging the brake hole 24 at an appropriate position, it can be ensured that the system can respond quickly when stopping or decelerating is required, thereby improving the safety of the equipment operation.

[0067] In some embodiments, the braking portion 422 has a friction surface. When the moving part 41 moves along the second direction, the second matching portion 421 drives the friction surface to come into frictional contact with the guide rail 23 under the action of the first matching portion 411. The contact of the friction surface can provide a controllable braking force. By adjusting the matching between the second matching portion 421 and the first matching portion 411 to adjust the force of the friction surface acting on the guide rail 23, precise control of the braking force can be achieved, thereby making the braking process more reliable and flexible. Since the friction surface has a certain friction coefficient, a precise braking effect can be achieved. The frictional contact between the braking portion 422 and the guide rail 23 can stop or decelerate the moving part 41 in a relatively short time, thereby ensuring the rapid response and accuracy of the braking process.

[0068] As for how to form the friction surface, processing operations such as grinding, spraying, coating, etc. can be performed on the surface of the braking part 422, so as to change the surface characteristics of the braking part 422 and form the friction surface.

[0069] In order to improve the stability of the moving module 30 running on the guide rail 23, the moving body 31 includes a plurality of rollers 33, and two adjacent rollers 33 are installed at intervals on the moving bracket 311 and slide with the guide rail 23. Fig. 9Among the at least two rollers 33 located on one side of the guide rail 23, the spacing between the axes of adjacent rollers 33 is a first distance L1; among the at least two rollers 33 located on the other side of the guide rail 23, the spacing between the axes of adjacent rollers 33 is a second distance L2; the first distance L1 is smaller than the second distance L2.

[0070] It should be noted that the curvature of the curved inner side surface of the guide rail 23 is the same everywhere. When the mover module 30 moves along the guide rail 23, the two rollers 33 on the left side always keep in contact with the curved inner side surface, ensuring that they can roll along the curved inner side surface of the guide rail 23. In order to ensure that at least one roller 33 on the right side is in contact with the guide rail 23 and rolls along the curved outer side surface of the guide rail 23, the spacing between the two rollers 33 on the right side can be set smaller. In this way, at least three rollers 33 will be in contact with the guide rail 23 to form a stable triangular structure, which improves the stability of the mover module 30 when running on the guide rail 23.

[0071] It is understandable that the number of rollers 33 is not limited to 4, but may also be 5, 6, etc. The number of rollers 33 located on the inner side of the guide rail 23 may be the same as or different from the number of rollers 33 located on the outer side of the guide rail 23. For example, the number of rollers 33 located on the inner side of the guide rail 23 is 2, and the number of rollers 33 located on the outer side of the guide rail 23 is 3.

[0072] The guide rail 23 can be installed in a variety of positions. In order to make rational use of space, the guide rail 23 is located at the bottom of the movable module 30 and the brake module 40. In this embodiment, the moving part 41 will drive the brake part 42 to move in the up and down directions to move closer to or away from the guide rail 23. Of course, the guide rail 23 can also be set to be located on the side of the movable module 30 away from the stator module 20. In this embodiment, the moving part 41 will drive the brake part 42 to move in the horizontal direction to move closer to or away from the guide rail 23. The movement direction of the brake part 42 can be changed by adapting the extension direction of the first matching part 411 and the second matching part 421. Here, the present application does not make any specific restrictions on the installation position of the guide rail 23.

[0073] The above-mentioned first permanent magnet array 312 and second permanent magnet array 413 may include at least one magnet module arranged along the extension direction of the coil assembly 22. Multiple magnet modules are detachably connected to the mover bracket 311 or the mounting seat 412 respectively. It can be understood that the connection between each magnet module and the mover bracket 311 or the mounting seat 412 is independent, that is, each magnet module can be disassembled and assembled from the mover bracket 311 or the mounting seat 412 separately. The magnet module may include four permanent magnets arranged along the extension direction of the coil assembly 22. The four permanent magnets may all be ordinary magnets or strong magnets, and their arrangement may be NSNS or SNSN. The multiple permanent magnets in the magnet module are arranged in a Halbach Array. It is understandable that the Halbach array is a magnetic structure that can generate a strong magnetic field with a small number of permanent magnets. The Halbach array can gather magnetic lines of force on one side of the magnet and weaken the magnetic lines of force on the other side of the magnet, thereby enhancing the strength of the magnetic field generated by the magnet module on the basis of the number of permanent magnets in the magnet module remaining unchanged, so as to obtain a more ideal unilateral magnetic field. It is understandable that the side with denser magnetic lines of force in the Halbach array should be arranged close to the coil assembly 22 to further enable the mover module 30 to obtain a greater driving force.
