Description

Technical Field

[0001] The utility model relates to the technical field of online production logistics transportation of industrial automation production lines, and in particular to a high-precision and high-load capacity magnetic drive annular track system. Background Art

[0002] The current magnetically driven circular track conveying system generally uses a single-sided V-shaped outward guide rail as the main guiding mechanism. Since it is necessary to ensure that the slider can pass through the turning of the guide rail smoothly, there is a certain guide rail gap between the rollers on both sides of the slider and the guide rail to avoid mechanical jamming caused by multiple groups of rollers passing through the turning successively. However, due to the guiding mode of the rollers of the guide rail slider in the single-track mode, the guide rail gap cannot be eliminated, resulting in poor accuracy and poor rigidity of the structural design. In addition, due to the existence of the guide rail gap, the slider on the guide rail cannot run at high speed to avoid the rollers colliding with the guide rail at the turning of the guide rail due to the centripetal force when the slider is running at high speed, or being squeezed at the guide rail, thereby accelerating the wear of the guide rail and reducing the service life of the track system.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a magnetic drive annular track system with high precision and high load capacity.

[0005] The technical solution of the utility model is as follows: a high-precision and high-load capacity magnetic drive annular track system is provided, comprising: a magnetic drive track body, guide rails arranged at the top and bottom of the magnetic drive track body, and a slider structure sleeved on the guide rails, wherein the main body of the slider structure is a C-shaped structure and is sleeved on the guide rails at the top and bottom of the magnetic drive track body at the same time, and the side walls of the slider structure corresponding to the guide rails are provided with rollers, and the rollers are in contact with the side walls of the guide rails.

[0006] Furthermore, the guide rail adopts a U-shaped guide rail, and the two side walls of the U-shaped guide rail are recessed inward to form a U-shaped structure on both sides of the U-shaped guide rail. The roller on the slider structure is provided with a protruding structure corresponding to the U-shaped structure, and the protruding structure is embedded in the U-shaped structure.

[0007] Furthermore, the slider structure is provided with a plurality of pairs of rollers corresponding to the guide rails on the top of the magnetic drive track body, and each pair of rollers is respectively provided on both sides of the guide rails.

[0008] Furthermore, the slider structure is provided with a plurality of pairs of rollers corresponding to the guide rail at the bottom of the magnetic drive track body, and each pair of rollers is respectively provided on both sides of the guide rail.

[0009] Furthermore, the slider structure is provided with a plurality of rollers corresponding to the guide rail at the bottom of the magnetic drive track body, and the rollers are arranged on the same side of the guide rail.

[0010] Furthermore, a magnetic drive coil is arranged inside the side wall of the magnetic drive track body, and the magnetic drive coil is arranged on the side of the magnetic drive track body facing the slider structure. A magnetic drive magnetic plate is arranged on the inner side wall of the C-shaped structure of the slider structure corresponding to the magnetic drive coil.

[0011] Furthermore, a position encoder is arranged inside the magnetic drive track body.

[0012] By adopting the above scheme, the utility model uses a slider structure to be simultaneously mounted on the guide rails at the top and bottom of the magnetic drive track body in a C-shaped structure, and contacts the side walls of the guide rails through rollers. Therefore, when the magnetic drive track body moves at a turning point, the bottom roller contacts the guide rails, thereby providing load support in the horizontal direction, thereby achieving a balance between the force and the supporting force of the slider structure, making the operation of the overall track system more stable and more precise, thereby avoiding the problem of reduced overall service life due to collision between the slider structure and the guide rail or the magnetic drive track body.

[0015] See also Figure 1 The utility model provides a high-precision and high-load capacity magnetic drive circular track system, comprising: a magnetic drive track body 1, a guide rail 2 arranged at the top and bottom of the magnetic drive track body 1, and a slider structure 3 sleeved on the guide rail 2, wherein the slider structure 3 has a C-shaped structure and is sleeved on the guide rails 2 at the top and bottom of the magnetic drive track body 1 at the same time, and the slider structure 3 is provided with rollers 31 corresponding to the side walls of the guide rail 2, and the rollers 31 are in contact with the side walls of the guide rail 2. The slider structure 3 is simultaneously mounted on the guide rails 2 at the top and bottom of the magnetic drive track body 1 in a C-shaped structure, and is in contact with the side walls of the guide rail 2 through the rollers 31, so that when the magnetic drive track body 1 moves at a turning point, the bottom rollers 3 are in contact with the guide rails, thereby providing load support in the horizontal direction, so that the force and support force of the slider structure 3 are balanced, so that the operation of the overall track system is more stable and accurate, thereby avoiding the problem of the slider structure 3 colliding with the guide rail 2 or the magnetic drive track body 1, which leads to a reduction in the overall service life.

[0016] The guide rail 2 is a U-shaped guide rail, and the two side walls of the U-shaped guide rail are recessed inward to form a U-shaped structure on both sides of the U-shaped guide rail. The roller 31 on the slider structure 3 is provided with a protruding structure corresponding to the U-shaped structure, and the protruding structure is embedded in the U-shaped structure. The U-shaped guide rail is adopted, so that the protruding structure of the outer side wall of the roller 31 is easily embedded in the U-shaped structure, providing a guiding effect for the movement of the roller 31, and providing a supporting force in the up and down directions for the roller 31, thereby improving the stability of the slider structure 3 during the movement on the guide rail 2.

[0017] The slider structure 3 is provided with a plurality of pairs of rollers 31 corresponding to the guide rail 2 at the top of the magnetic drive track body 1, and each pair of rollers 31 is respectively provided on both sides of the guide rail 2. In some embodiments, the slider structure 3 corresponding to the top guide rail 2 is provided with four rollers 31 divided into two groups, and each group of rollers 31 is respectively provided on both sides of the guide rail 2 and interlocked with the side walls of the guide rail 2, thereby providing the main support for the load in the vertical direction, thereby ensuring the stability and movement accuracy of the slider structure 3 during the movement on the guide rail 2.

[0018] In some embodiments, the slider structure 3 is provided with a plurality of pairs of rollers 31 corresponding to the guide rail 2 at the bottom of the magnetic drive track body 1, and each pair of rollers is respectively provided on both sides of the guide rail. By providing multiple groups of rollers 31 on the slider structure 3 corresponding to the bottom guide rail 2, and each group of rollers 31 is provided on both sides of the guide rail 2, the slider structure 3 is provided with a horizontal load by cooperating with the pulley 31 corresponding to the top guide rail 2 at the turning point of the track, so as to avoid the slider structure 3 being deflected by the centripetal force at the turning point.

[0019] In some embodiments, the slider structure 3 is provided with a plurality of rollers 31 corresponding to the guide rail 2 at the bottom of the magnetic drive track body 1, and the rollers 31 are provided on the same side of the guide rail 2. By providing a plurality of rollers 31 on the slider structure 3 corresponding to the guide rail 2 at the bottom, and making the rollers 31 provided on the same side of the guide rail 2, the rollers 31 are generally provided on the outside of the turning part of the guide rail 2, so that when the slider structure 3 moves at the turning part of the guide rail 2, the rollers 31 contact the outside of the guide rail 2, thereby eliminating the centripetal force generated during the turning process, providing effective support in the horizontal direction, and improving the stability of the slider structure 3 during the movement process.

The magnetic drive coil 11 is disposed on the side of the magnetic drive track body 1 facing the slider structure 3. A magnetic drive magnetic plate 32 is disposed on the inner side wall of the C-shaped structure of the slider structure 3 corresponding to the magnetic drive coil 11. The magnetic drive coil 11 is disposed in the middle position of the supporting force of the upper and lower sections of the guide rail 2, so that the force on the upper and lower sides of the magnetic drive coil 11 is balanced, so that the force and the supporting force are kept in a balanced state, so that the operation of the overall track system is more stable, and the service life of the guide rail 2 and the slider structure 3 is guaranteed.

[0021] A position encoder 12 is disposed inside the magnetic drive track body 1 to provide higher and more stable precision position feedback, thereby meeting the control accuracy requirements for the moving position and moving distance of the slider structure.

[0022] To summarize, the utility model uses a slider structure in a C-shaped structure to be simultaneously mounted on the guide rails at the top and bottom of the magnetic drive track body, and contacts the side walls of the guide rails through rollers. When the magnetic drive track body moves at a turning point, the bottom roller contacts the guide rails to provide load support in the horizontal direction, thereby achieving a balance between the force and the supporting force of the slider structure, making the operation of the overall track system more stable and more precise, thereby avoiding the problem of reduced overall service life due to collision between the slider structure and the guide rail or the magnetic drive track body.
