[0032] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In the related art, the magnetically driven conveyor line includes a stator and a mover. The mover is generally mounted on the stator and slidably connected to the stator. The conveyor line is used in conjunction with an actuator, and the actuator processes the workpiece transported on the mover. However, due to the low height of some actuators, it is difficult to directly process the workpiece placed above the mover. If the conveyor line is disassembled and reassembled or the actuator is raised, the cost of using the conveyor line will be greatly increased.

[0034] For the above situation, please see Figure 1-Figure 3 The present application proposes a conveyor line 1, including a conveying component 10 and a movable component 20, wherein the movable component 20 can move on the conveying component 10 to transport workpieces, wherein a plurality of movable components 20 are arranged on the conveying component 10, and the plurality of movable components 20 can move synchronously on the conveying component 10, and the conveyor line 1 can be a linear conveyor line or a circular conveyor line.

[0035] The conveying assembly 10 includes a base 11 and a stator module 12 arranged on the base 11. The stator module 12 is spaced apart from the base 11. The stator module 12 includes an armature winding 121 and a guide rail 122. The armature winding 121 and the guide rail 122 both extend along the conveying direction of the conveying line 1. The guide rail 122 is located on the side of the armature winding 121 away from the base 11; the mover assembly 20 includes a mover body 21 and a sliding member 22 arranged on the mover body 21. The sliding member 22 is slidably connected to the guide rail 122. The mover body 21 is magnetically coupled with the armature winding 121 to drive the mover body 21 to move relative to the stator module 12. The mover body 21 has a bearing surface 211 facing the base 11. A accommodating space 23 is defined between the bearing surface 211 and the base 11. The bearing surface 211 is used to carry the workpiece for transportation in the accommodating space 23.

[0036] Specifically, the armature winding 121 is located between the base 11 and the guide rail 122, and the sliding member 22 and the guide rail 122 can slide along the conveying direction of the conveyor line 1, and there is also a force between the sliding member 22 and the guide rail 122, so that the guide rail 122 provides support for the mover assembly 20. Among them, the base 11 on the conveyor line 1 and the external actuator are both arranged on a processing platform, and the actuator processes the workpiece transported on the conveyor line 1. The bearing surface 211 on the mover body 21 is arranged away from the guide rail 122, so that the workpiece on the bearing surface 211 is located in the accommodating space 23 close to the base 11, thereby shortening the distance between the workpiece and the actuator, and the accommodating space 23 can provide protection for the transportation of the workpiece, thereby improving the transportation stability of the workpiece.

[0037] It should be noted that, in the embodiment of the present application, the armature winding 121 is arranged between the guide rail 122 and the base 11, and the workpiece is transported in the accommodation space 23 between the bearing surface 211 and the base 11. Compared with arranging the workpiece above the mover body 21, on the one hand, this embodiment can make the accommodation space 23 provide protection for the transportation of the workpiece, reduce the interference of external factors (such as collision with foreign objects or accidental touch by workers, etc.) on the transportation of the workpiece, and improve the transportation stability of the workpiece. On the other hand, this embodiment can also shorten the distance between the workpiece and the base 11, that is, reduce the transportation height of the workpiece, reduce the distance between the actuator and the workpiece, so that the conveyor line 1 can be adapted to actuators with lower heights. Among them, the conveyor line 1 in this embodiment can be adapted to various types of actuators, and there is no need to re-disassemble the conveyor line 1 according to the height of the actuator, which improves the universality of the conveyor line 1.

[0038] Exemplarily, a bearing member is disposed on the bearing surface 211 of the mover body 21 , and the bearing member includes a bearing frame or a clamp. The bearing member can fix the workpiece on the bearing surface 211 to reduce shaking or position displacement of the workpiece during transportation.

[0039] In some embodiments, Figure 2-Figure 4 As shown, the processing platform has a first surface for placing the conveyor line 1 and the actuator, the first surface is parallel to the horizontal plane, the base 11 on the conveyor line 1 is arranged on the first surface, the guide rail 122 and the armature winding 121 are arranged vertically, the mover body 21 includes two permanent magnet arrays 212 arranged vertically relative to each other, the armature winding 121 is located between the two permanent magnet arrays 212, and is magnetically coupled with the permanent magnet array 212 to drive the mover body 21 to move.

[0040] Specifically, two permanent magnet arrays 212 are sandwiched on opposite sides of the armature winding 121 to drive the mover body 21 to move along the conveyor line 1 in the form of current excitation or traveling wave magnetic field with the armature winding 121. At the same time, the armature winding 121 can also provide a vertical upward support force for the mover body 21, so that the setting of the mover body 21 is more stable. Each permanent magnet array 212 may include one permanent magnet or multiple permanent magnets, and the multiple permanent magnets are arranged along the extension direction of the armature winding 121.

[0041] See also Figure 2 In some embodiments of the present application, the conveying assembly 10 also includes a frame 13 connected to the base 11, the frame 13 and the base 11 together form an installation cavity 131, the stator module 12 is located in the installation cavity 131, the installation cavity 131 provides a setting foundation and installation space for the stator module 12, the frame 13 can provide protection for the stator module 12 and reduce the stator module 12 from external interference.

[0042] Among them, the stator module 12 can be arranged on the base 11, so that the mover body 21 can slide more stably on the stator module 12, reducing the probability of relative displacement between the stator module 12 and the base 11 when the mover body 21 slides; or, the frame 13 is mounted on the base 11, and the stator module 12 is arranged on the frame 13, so there is a space gap between the stator module 12 and the base 11, which is conducive to providing transportation space for the workpiece; or, the stator module 12 is connected to both the base 11 and the frame 13, which not only makes the stator module 12 more firmly arranged, but also makes the frame 13 more stable.

[0043] Further, such as Figure 1-Figure 2 As shown, the frame 13 includes an upper cover 132 and a connecting rod 133, one end of the connecting rod 133 is connected to the upper cover 132, and the other end of the connecting rod 133 is connected to the base 11. The connecting rod 133 can be extended and retracted relative to the base 11 to change the distance between the upper cover 132 and the base 11, that is, the size of the installation cavity 131 can be changed, thereby controlling the size of the accommodating space 23 between the bearing surface 211 and the base 11.

[0044] For example, the connecting rod 133 includes a first set of rods and a second set of rods, the first set of rods is sleeved on the outer periphery of the second set of rods, and the first set of rods can slide relative to the second set of rods to change the distance between the upper cover 132 and the base 11; for another example, the upper cover 132 has a first through hole, one end of the connecting rod 133 passes through the first through hole to be slidably connected to the upper cover 132, thereby changing the distance between the upper cover 132 and the base 11; for another example, the base 11 has a second through hole, the other end of the connecting rod 133 passes through the second through hole to be slidably connected to the base 11, thereby changing the distance between the upper cover 132 and the base 11.

[0045] Exemplarily, the base 11 includes a first part 111 and a second part 112 connected to each other, the first part 111 is fixedly connected to the frame 13, and the first part 111 and the frame 13 enclose an installation cavity 131, the second part 112 and the stator module 12 are both located in the installation cavity 131, and the guide rail 122 is fixedly installed on the upper cover 132.

[0046] See also Figure 3-Figure 4 In some embodiments of the present application, the sliding member 22 includes a roller 221 group. When the mover body 21 and the armature winding 121 move through magnetic coupling, the roller 221 group rolls relative to the guide rail 122. The roller 221 group can be located on the side of the guide rail 122 away from the mover body 21, that is, the roller 221 group is rollingly connected to the side of the guide rail 122 away from the mover body 21, so that the roller 221 group can provide support for the mover body 21 while rolling, so that the mover body 21 can slide more stably relative to the stator module 12.

[0047] At least one group of rollers 221 is provided, and one group of rollers 221 includes at least two rollers 221. The axle of the roller 221 is perpendicular to the bearing surface 211 and is connected to the mover body 21. The roller 221 is rollingly connected to the guide rail 122, and the two rollers 221 are clamped on opposite sides of the guide rail 122. The clamping force between the roller 221 and the guide rail 122 can provide support for the mover body 21, so that the mover body 21 remains stable during operation.

[0048] For further information, see Figure 5 In some embodiments of the present application, the circumferential side of the roller 221 has a groove 222, and the opposite sides of the guide rail 122 are provided with protrusions 1221, and the protrusions 1221 are located in the groove 222. When the mover body 21 moves relative to the stator 123, the roller 221 rolls along the protrusions 1221.

[0049] It is easy to understand that the protrusion 1221 cooperates with the groove 222 to support and limit the mover body 21, and make the mover body 21 have higher motion accuracy when moving. Exemplarily, the groove 222 is a V-shaped groove, and the protrusion 1221 is a V-shaped slide rail, which is inserted into the V-shaped groove and cooperates with the V-shaped groove.

[0050] Alternatively, see Figure 6 In some embodiments of the present application, the guide rail 122 includes a suspension rod 1222, and the sliding member 22 includes a ring 222. The ring 222 is sleeved on the suspension rod 1222, and the ring 222 is slidably connected to the suspension rod 1222. It can be understood that the suspension rod 1222 extends along the conveying direction of the conveyor line 1. When the mover body 21 moves, it can drive the ring 222 to slide relative to the suspension rod 1222. At the same time, the suspension rod 1222 has a supporting force on the ring 222, which is beneficial to ensure the stability of the mover body 21.

[0051] Further, in some embodiments of the present application, the suspension rod 1222 has a support surface (not shown in the figure) away from the armature winding 121, the support surface is in contact with the suspension ring 222, and the support surface is an arc-shaped surface, so the friction generated between the arc-shaped support surface and the suspension ring 222 is small, thereby reducing the obstacle of the suspension rod 1222 to the sliding of the suspension ring 222, making the sliding of the suspension ring 222 smoother. The cross section of the suspension rod 1222 can be circular, elliptical or irregular.

[0052] See also Figure 4 In some embodiments of the present application, the conveyor line 1 also includes a circuit board 30, which is electrically connected to the armature winding 121. The circuit board 30 is located between the base 11 and the stator module 12, and the circuit board 30 is extended vertically. The base 11, the circuit board 30 and the bearing surface 211 together enclose a receiving space 23.

[0053] Specifically, the external power supply energizes the armature winding 121 through the circuit board 30. The circuit board 30 serves as the main power supply and control component of the conveyor line 1. The circuit board 30 needs to occupy the installation space of the conveyor line 1. The circuit board 30 is vertically arranged between the base 11 and the stator module 12 to facilitate power supply to the armature winding 121.

[0054] In some embodiments of the present application, Figure 1-Figure 2 As shown, the circuit board 30 is arranged in a ring shape; the stator module 12 includes a plurality of stators 123, each stator 123 includes an armature winding 121 and a guide rail 122, and the plurality of stators 123 are connected in sequence to form a ring-shaped stator module 12, so the conveyor line 1 is ring-shaped as a whole.

[0055] Specifically, the plurality of stators 123 are arranged around the outer side of the circuit board 30, and the stator module 12 and the base 11 are respectively located on opposite sides of the circuit board 30, so the stator module 12, the circuit board 30 and the base 11 together enclose an annular accommodation space 23, so that the workpiece can be transported in the accommodation space 23. Among them, the circuit board 30 can form a side wall of the accommodation space 23, and there is no need to expand and occupy the radial space of the annular conveyor line 1 to arrange the circuit board 30, which is conducive to the miniaturization of the annular conveyor line 1.

[0056] For further information, see Figure 7 In some embodiments of the present application, the conveyor line 1 also includes an electric control box 40, which is disposed on the base 11 and is electrically connected to the circuit board 30. The electric control box 40 includes components such as cables, optical fibers, and a controller. The cables are used to supply power to the circuit board 30 and the armature winding 121, and the optical fibers and the controller can also transmit information to the stator module 12.

[0057] In some embodiments, walking wheels are provided at the bottom of the base 11, and the conveyor line 1 as a whole can be moved according to actual usage, so that the electric control box 40 can move with the conveying component 10, thereby reducing the pulling of the cables by the conveyor line 1 during movement.
