Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a magnetically driven conveyor line. Background Technology

[0002] Traditional magnetic drive lines are generally placed horizontally. However, in some special scenarios, such as semiconductor manufacturing, wafers need to be transported precisely in a highly clean environment to prevent tiny dust particles or contaminants from affecting wafer quality and performance, thus reducing the risk of contamination. To reduce costs, it is necessary to improve the efficiency and flexibility of the production line within a limited space. Similarly, automobile manufacturers need to optimize assembly lines within limited space to reduce floor space requirements.

[0003] In response, a magnetic drive conveyor line is provided that uses a vertical circular track, which reduces the size of the magnetic drive conveyor line. However, in high-speed transport scenarios, this magnetic drive conveyor line has poor stability and is prone to vibration and noise. Utility Model Content

[0027] Please refer to Figure 1 and Figure 2 This application provides a magnetic drive conveyor line, including a frame 100, a magnetic drive stator 200, and a magnetic drive unit 300. The frame 100 supports the magnetic drive stator 200, and the magnetic drive unit 300 carries materials. The magnetic drive unit 300 is disposed on the magnetic drive stator 200 and can be driven by the magnetic drive stator 200 to move in order to transport materials.

[0028] The magnetic drive stator 200 has a ring track 210, along which the magnetic drive motor 300 moves. The ring track 210 is set in a vertical plane, which is a plane perpendicular to the horizontal plane. By setting the ring track 210 vertically, its occupation of ground space is reduced, thereby improving the utilization rate of factory space.

[0029] The magnetic actuator 300 includes multiple rollers 310, which can roll against the magnetic drive stator 200 to realize the movement of the magnetic actuator 300 relative to the magnetic drive stator 200.

[0030] Multiple rollers 310 are divided into a first roller group 311 and a second roller group 312 along the height direction of the magnetic drive stator 200. There is a gap between the first roller group 311 and the second roller group 312 along the height direction of the magnetic drive stator 200, and an annular track 210 is located at the gap between the first roller group 311 and the second roller group 312. The first roller group 311 can be positioned above the annular track 210, while the second roller group 312 is located below the annular track 210, with both groups clamped onto the annular track 210. Thus, when the magnetic drive unit 300 is in different positions on the annular track 210, one of the first roller group 311 and the second roller group 312 can provide support, and the two groups also cooperate to provide guidance.

[0031] The annular track 210 has a protrusion 211 extending along the height direction of the magnetic drive stator 200. The protrusion 211 can be upward, downward, or partially upward and partially downward. The protrusion 211 extends along the extension direction of the annular track 210, and the roller 310 has a groove 313 adapted to the protrusion 211. The groove 313 cooperates with the protrusion 211 to limit the relative position of the magnetic drive unit 300 and the magnetic drive stator 200 along the width direction of the magnetic drive stator 200, preventing the magnetic drive unit 300 from shifting or falling off.

[0032] In the above embodiments, by arranging the annular track 210 in a vertical plane, the magnetic drive conveyor line reduces the ground space occupied and improves the utilization rate of factory space. By positioning the annular track 210 between the first roller group 311 and the second roller group 312, the displacement of the magnetic drive unit 300 relative to the annular track 210 along the height direction of the magnetic drive stator 200 is limited by the annular track 210. The groove 313 adapts to the protrusion 211, thereby limiting the displacement of the magnetic drive unit 300 relative to the annular track 210 along the width direction. Thus, while improving the utilization rate of factory space, limiting the displacement of the magnetic drive unit 300 relative to the magnetic drive stator 200 in multiple directions improves stability in high-speed scenarios and reduces noise.

[0033] In some embodiments, the circular track 210 includes two straight segments spaced apart along its own height, and two arcuate segments positioned opposite each other and connecting the two straight segments. The two arcuate segments are located at the ends of the two straight segments, forming a closed circular path. The connection between the two straight segments and the two arcuate segments is designed for a smooth transition.

[0034] In some embodiments, there are two sets of annular tracks 210. The magnetic drive stator 200 includes a mounting base 220, which can be a plate structure extending along the length of the magnetic drive stator 200 and along its width. Two sets of annular tracks 210 are disposed on both sides of the mounting base 220; that is, one set of annular tracks 210 is disposed on one side of the mounting base 220 in the thickness direction, and the other set is disposed on the other side. It is understood that the two sets of annular tracks 210 share a common mounting reference, which improves stability during operation. In some specific embodiments, the two sets of annular tracks 210 are arranged symmetrically to further improve stability.

[0035] In some embodiments, the magnetic actuator 300 includes two sets of movable seats 320, which can be plate structures and are arranged in parallel with the fixed seat 220, with the fixed seat 220 located between the two sets of movable seats 320.

[0036] Multiple rollers 310 are divided into a third roller group and a fourth roller group along the width direction of the magnetic drive stator 200. The third roller group is located on the side of one set of movable seats 320 facing the fixed seat 220, and the fourth roller group is located on the side of another set of movable seats 320 facing the fixed seat 220. This arrangement ensures that the magnetic drive unit 300 is subjected to balanced forces during operation, thereby enhancing the stability of the magnetic drive unit 300.

[0037] The third and fourth roller groups have the same number of rollers and are symmetrically arranged on both sides of the width direction of the fixed base 220.

[0038] In some specific embodiments, each roller 310 has a groove 313, and the synergistic effect of the third roller group and the fourth roller group further enhances the stability of the magnetic actuator 300 on the circular track 210.

[0039] In some embodiments, the magnetic actuator 300 includes a stage 330, which is the part that carries materials, and a movable seat 320 is connected to the stage 330. The connection method between the two is not limited; for example, it can be a fastening connection or a welding connection.

[0040] The magnetic drive stator 200 includes a base 230, which is a supporting structure for the magnetic drive stator 200. The base 230 is connected to a mounting base 220. In some specific embodiments, the outer peripheral surface of the base 230 has a mounting groove 230a, at least a portion of the mounting base 220 is located within the mounting groove 230a, and the mounting base 220 does not extend beyond the mounting groove 230a.

[0041] The weight of the material can be transferred to the annular track 210 via the platform 330, the movable seat 320, and the rollers 310, and then distributed to the fixed seat 220 and the base 230. The outer circumferential surfaces of the platform 330 and the base 230 are arranged opposite each other, so that the weight of the material can be transferred relatively evenly to the annular tracks 210 on both sides, thereby improving the load-bearing capacity and stability of the overall structure and ensuring balance during high-speed operation. In some specific embodiments, the platform 330 is symmetrically arranged relative to the fixed seat 220 along the width direction of the magnetic drive stator 200, and the two sets of movable seats 320 are symmetrically arranged relative to the fixed seat 220.

[0042] In some embodiments, the magnetic drive stator 200 includes a coil 240 for generating a magnetic field to drive the magnetic drive element 300. The outer peripheral surface of the base 230 is provided with a mounting groove 230a, and the coil 240 is disposed on both side walls of the mounting groove 230a. Each of the two sets of movable seats 320 has a magnetic plate 340 on its side facing away from the fixed base 220 for induction with the coil 240. The coils 240 on both sides induction with the magnetic plates 340 on each set of movable seats 320 optimizes the magnetic field distribution and further improves the dynamic balance of the magnetic drive element 300 during movement.

[0043] In some embodiments, the magnetic actuator 300 includes two sets of movable seats 320, with a fixed seat 220 located between the two sets of movable seats 320. At least a portion of the fixed seat 220 is located within a mounting groove 230a. The movable seats 320, the fixed seat 220, and the mounting groove 230a partially overlap in the height direction. This reduces the overall height and makes the structure more compact.

[0044] In some embodiments, the annular track 210 includes a mounting portion 212 for connecting to a fixed base 220. A protrusion 211 is disposed on the mounting portion 212, protruding from the mounting portion 212 along the height direction of the magnetic drive stator 200. A gap exists between the protrusion 211 and the fixed base 220, and a portion of the roller 310 is located within this gap. Specifically, the protrusion 211 is located on the side of the mounting portion 212 facing away from the fixed base 220, thus creating a gap between the protrusion 211 and the fixed base 220. The groove 313 of the roller 310 is located at the middle of the width direction of the roller 310. When the groove 313 is fitted with the protrusion 211, a portion of the roller 310 is located within the aforementioned gap.

[0045] In some specific embodiments, the mounting portion 212 and the protrusion 211 are integrally formed, with the protrusion 211 at the top of the mounting portion 212 protruding upward from the mounting portion 212, and the protrusion 211 at the bottom of the mounting portion 212 protruding downward from the mounting portion 212.

[0046] In some embodiments, the protrusion 211 includes a first abutment surface and a second abutment surface distributed along the width direction of the magnetic drive stator 200. The first abutment surface and the second abutment surface intersect, and the groove 313 of the roller 310 is adapted to the first abutment surface and the second abutment surface. In this way, while restricting the lateral movement of the roller 310, it is ensured that it runs along the annular track 210.

[0047] The shapes of the first and second contact surfaces are not limited. In some specific embodiments, the first and second contact surfaces are planes, which make the protrusion 211 present an inverted V shape. Correspondingly, the rolling groove 313 of the roller 310 is a V-shaped groove.

[0048] In some embodiments, the frame 100 includes a base frame 110, a support frame 120, and wheels 130. The support frame 120 is connected to the magnetic drive stator 200, the base frame 110 supports the support frame 120, and the wheels 130 are mounted on the base frame 110, thereby enabling rapid movement to adjust the position of the magnetic drive conveyor line as needed. The support frame 120 is connected to the base 230, the base frame 110 has a rectangular frame structure, and the wheels 130 are mounted on the bottom of the base frame 110.

[0049] In some embodiments, the magnetic drive conveyor line also includes an RFID module 400, which is disposed at the interval between the stage 330 and the base 230. The RFID module 400 is a radio frequency identification module used to identify the serial number or material number of the magnetic drive unit 300.

[0050] The magnetic drive conveyor line also includes a magnetic grid 500, which is set on the fixed base 220 and the magnetic drive 300 to obtain the position of the magnetic drive 300 on the magnetic drive stator 200.
