Description

Technical Field

[0001] This invention relates to the field of magnetic drive conveying devices, and in particular to a magnetic drive and a magnetic drive conveying device. Background Technology

[0002] Current magnetic drive conveyor lines use the magnetic force between the stator coils and the permanent magnets of the mover to drive the mover along a track, reducing mechanical wear on moving parts such as belts and chains, and thus reducing particulate matter generation. However, because magnetic drive conveyor lines still require a track for conductors and support of the mover, friction still exists between the mover and the track, and the resulting particulate matter can pollute the environment. Therefore, the application of magnetic drive conveyor lines in industries with high environmental cleanliness requirements, such as semiconductors, batteries, and biopharmaceuticals, remains limited. Furthermore, due to space constraints, the thrust exerted by the stator on the mover is limited, thus limiting the load-bearing capacity of the mover. In heavy-duty scenarios, multiple movers need to be hinged together to drive the load, increasing installation and commissioning time costs, and the hinged structure also increases particulate matter generation. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned problems by providing a magnetic actuator and a magnetic drive conveying device, thereby solving the aforementioned problems.

[0004] A magnetic actuator includes: a first permanent magnet module, a second permanent magnet module, an upper plate, and side plates. The left and right sides of the upper plate are respectively connected to guide elements. The lower part of the upper plate is fixedly connected to the first permanent magnet module. The left and right sides of the upper plate are respectively fixedly and detachably connected to the side plates. The opposite sides of the side plates are respectively fixedly connected to the second permanent magnet module. The upper plate and the left and right side plates form a second inner cavity. The front and rear ends and the lower end of the second inner cavity are respectively formed with openings.

[0005] Furthermore, the guide element is a V-shaped guide roller, which is rotatably connected to the upper plate, and the front and rear pairs of guide elements are respectively arranged between the upper plate and the side plate.

[0006] A magnetic drive conveying device using the aforementioned magnetic drive unit further includes: a track box, a first stator module, and a first permanent magnet module. The track box includes an upper mounting plate and side mounting plates. The left and right sides of the upper mounting plate are respectively fixedly connected to the side mounting plates. The upper mounting plate and the left and right side mounting plates form a first inner cavity. The magnetic drive unit is fitted onto the outside of the track box. The upper mounting plate is fixedly connected to the first stator module at its top. The opposite sides of the left and right side mounting plates are respectively fixedly connected to the first permanent magnet module. The second stator module corresponds one-to-one with the second permanent magnet module and drives the second permanent magnet module through magnetic force. The first stator module corresponds to the first permanent magnet module and drives the first permanent magnet module through magnetic force.

[0007] Furthermore, a connecting portion is formed between the upper mounting plate and the side mounting plate, and a corner portion extending along the length direction of the track box is formed on the outer side of the connecting portion. The guide element contacts the corner portion and moves along the corner portion direction.

[0008] Furthermore, the corner is an acute angle, and the corner is used to restrict the movement of the guide element in the left-right and up-down directions.

[0009] Furthermore, a first through hole is formed in the middle of the corner, and a second through hole is formed on the inner side and below the first through hole, respectively. The two ends of the first through hole and the second through hole are connected to the first inner cavity and the second inner cavity, respectively.

[0010] Furthermore, the connecting portion has outwardly protruding baffles on the side near the upper mounting plate and the side near the side mounting plate, respectively.

[0011] Furthermore, it also includes a sealing plate, and the track box also includes a base. The side mounting plate is fixedly connected to the base below. The sealing plate is located between the bases on the left and right sides and is fixed to the base. An air outlet pipe is formed in the middle of the sealing plate. The upper end of the air outlet pipe is connected to the first inner cavity and the lower end is connected to the negative pressure device through a pipe.

[0012] Furthermore, both the upper mounting plate and the side mounting plate are flat plates, with the upper ends of the side mounting plates fixedly connected to the upper mounting plate and the lower ends inclined inwards.

[0013] Furthermore, it also includes a positioning block, with multiple track boxes connected end to end, adjacent track boxes contacting and fixed to each other, and two positioning posts formed below the positioning block. The two positioning posts of the same positioning block are respectively inserted into the second through holes of the adjacent track boxes. The lower side of the positioning block fits against the upper side of the connecting part, and blind holes are formed on the end faces of adjacent track boxes. The two ends of the pin shaft are respectively inserted into the blind holes of the adjacent track boxes.

[0014] The present invention has the following advantages: 1. The semi-enclosed magnetic actuator has permanent magnets arranged on three sides, which increases the thrust of the actuator and the load-bearing capacity of the actuator within a limited space; 2. The semi-enclosed magnetic actuator acts as a shield, preventing particles from spreading outward and keeping them near the connection. The first and second through holes draw in particles through airflow. After entering the first inner cavity, the particles are discharged from the outlet pipe with the airflow, reducing the impact of particles on the cleanliness of the external environment and thus meeting the requirements for application in high-cleanliness workshops. 3. During the airflow process, both sides of the first stator module and the second stator module are cooled simultaneously, reducing the temperature of the first stator module and the second stator module, increasing the magnetic force generated by the first stator module and the second stator module, and further increasing the load capacity of the magnetic actuator.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and examples: Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example 1: like Figures 1 to 6 As shown, this embodiment provides a magnetic actuator, including: a first permanent magnet module 5, a second permanent magnet module 6, an upper plate 21, and side plates 22. The left and right sides of the upper plate 21 are respectively connected to guide elements 23. The lower part of the upper plate 21 is fixedly connected to the first permanent magnet module 5. The left and right sides of the upper plate 21 are respectively fixedly and detachably connected to the side plates 22. The opposite sides of the side plates 22 are respectively fixedly connected to the second permanent magnet module 6. The upper plate 21 and the left and right side plates 22 form a second inner cavity 20. The front and rear ends and the lower end of the second inner cavity 20 are respectively formed with openings.

[0020] Furthermore, the guide element 23 is a V-shaped guide roller, and the guide element 23 is rotatably connected to the upper plate 21. The front and rear pairs of guide elements 23 are respectively arranged between the upper plate 21 and the side plate 22.

[0021] In use, one or two side plates can be used depending on the load capacity required for the magnetic actuator 2. For light loads, only the upper plate 21 is used; for medium loads, one side plate 22 is used; and for heavy loads, both side plates 22 are used. When the operating environment requires high cleanliness, both side plates 22 are used simultaneously. The upper plate 21 and side plates 22 act as shielding, reducing the outward diffusion of particles generated by friction between the guide element 23 and the guide rail, thus maintaining the cleanliness of the environment outside the magnetic actuator 2.

[0022] Furthermore, the lower end of the side plate 22 is inclined inward, and the upper plate 21 and the side plate 22 form an inverted triangle to reduce the width of the opening below, thereby reducing the number of particles that diffuse outward.

[0023] Example 2: like Figures 1 to 6 As shown, this embodiment provides a magnetic drive conveying device using the magnetic drive unit described in Embodiment 1, further comprising: a track box 1, a first stator module 3, and a first permanent magnet module 5. The track box 1 includes an upper mounting plate 11 and side mounting plates 12. The left and right sides of the upper mounting plate 11 are fixedly connected to the side mounting plates 12 respectively. The upper mounting plate 11 and the left and right side mounting plates 12 form a first inner cavity 10. The magnetic drive unit 2 is fitted on the outside of the track box 1. The upper mounting plate 11 is fixedly connected to the first stator module 3 at its top. The opposite sides of the left and right side mounting plates 12 are fixedly connected to the first permanent magnet module 5 respectively. The second stator module 4 and the second permanent magnet module 6 correspond one-to-one and are driven by magnetic force. The first stator module 3 and the first permanent magnet module 5 correspond to each other and are driven by magnetic force.

[0024] Furthermore, a connecting portion 13 is formed between the upper mounting plate 11 and the side mounting plate 12, and a corner portion extending along the length direction of the track box 1 is formed on the outer side of the connecting portion 13. The guide element 23 contacts the corner portion and moves along the corner portion direction.

[0025] Furthermore, such as Figure 4 and Figure 5 As shown, the corner is an acute angle, and the corner is used to restrict the movement of the guide element 23 in the left-right and up-down directions.

[0026] Furthermore, a first through hole 131 is formed in the middle of the corner, and a second through hole 132 is formed on the inner side and below the first through hole 131, respectively. The two ends of the first through hole 131 and the second through hole 132 are respectively connected to the first inner cavity 10 and the second inner cavity 20.

[0027] Furthermore, the connecting portion 13 has outwardly protruding baffles 133 on the side near the upper mounting plate 11 and the side near the side mounting plate 12, respectively, and the baffles 133 are used to block the diffusion of particles.

[0028] Furthermore, it also includes a sealing plate 7, and the track box 1 also includes a base 14. The side mounting plate 12 is fixedly connected to the base 14 below. The sealing plate 7 is located between the base 14 on the left and right sides and is fixed to the base 14. An air outlet pipe 71 is formed in the middle of the sealing plate 7. The upper end of the air outlet pipe 71 is connected to the first inner cavity 10 and the lower end is connected to the negative pressure device through a pipe.

[0029] Preferably, the negative pressure device is a fan. The upper surface of the sealing plate 7 has a structure with a lower center and a wider perimeter to facilitate the flow of particles towards the air outlet pipe 71.

[0030] Furthermore, both the upper mounting plate 11 and the side mounting plate 12 are flat plates. The upper ends of the side mounting plates 12 are fixedly connected to the upper mounting plate 11, and the lower ends are inclined inward. The inclined inner surfaces facilitate the downward movement of particles.

[0031] Preferably, heat dissipation fins are formed on the inner surfaces of the upper mounting plate 11 and the side mounting plate 12 to increase the heat exchange efficiency with the air.

[0032] Furthermore, it also includes a positioning block 8, with multiple track boxes 1 connected end to end, adjacent track boxes 1 contacting and fixed to each other. Two positioning posts 81 are formed below the positioning block 8. The two positioning posts 81 of the same positioning block 8 are respectively inserted into the second through holes 132 of adjacent track boxes 1. The lower side of the positioning block 8 is in contact with the upper side of the connecting part 13. Blind holes 15 are formed on the end faces of adjacent track boxes 1, and the two ends of the pin are respectively inserted into the blind holes 15 of adjacent track boxes 1. The positioning posts 81 and the second through holes 132 have the same radius. The pins and the blind holes 15 have the same radius. During installation, multiple track boxes 1 are placed on top of the frame (not shown in the figure). First, pins are used to limit the left-right and up-down directions of adjacent track boxes 1. Then, positioning blocks 8 are used to limit the front-back directions of adjacent track boxes 1. Finally, bolts are used to fix the track boxes 1 to the frame through the through holes of the base 14. The corresponding holes in the frame and base 14 can be elongated holes to facilitate the adjustment of the track boxes 1. The air outlet pipe 71 is inserted downwards into the frame and connected to the pipeline.

[0033] Preferably, the blind hole 15 is divided into a coaxial open hole and a threaded hole, and the pin contacts the open hole during positioning. When it is necessary to adjust the length of the track box 1 ( Figure 4 When sealing the openings at both ends (front and back), a cover plate can be used to block the opening. Then, screws are used to pass through the cover plate and threadedly connect it to the blind hole 15 to fix the cover plate to the track box 1, thereby ensuring that the first inner cavity 10 is connected to the outside only through the first through hole 131 and the second through hole 132.

[0034] It should be noted that sealing strips are installed between track boxes 1, and between track box 1 and the frame and cover plate, for sealing purposes.

[0035] Working principle: During operation, the first stator module 3 and the second stator module 4 respectively drive the first permanent magnet module 5 and the second permanent magnet module 6 to move along the corners of the track box 1, thereby increasing the thrust on the magnetic actuator 2. For example, Figure 2 and Figure 4 As shown, the two sides of the corner are adapted to the V-shaped guide rollers.

[0036] While the magnetic actuator 2 is moving, the negative pressure device remains operational, keeping the first inner cavity 10 under negative pressure. Driven by the negative pressure, the air outside the track box 1 moves toward the first through hole 131 and the second through hole 132, and after passing through the first through hole 131 and the second through hole 132, it enters the interior of the first inner cavity 10 and is finally discharged from the air outlet pipe 71.

[0037] During operation, friction between the guide element 23 and its corner generates a small amount of particles, which may contaminate the surrounding environment. After the particles are generated, the semi-enclosed magnetic actuator 2 acts as a shield, preventing the particles from spreading outward and keeping them near the connection part 13. Subsequently, the first through hole 131 draws in particles from the center of the guide element 23 through airflow, and the second through hole 132 draws in particles from both sides of the guide element 23 through airflow. After entering the first inner cavity 10, the particles are discharged from the air outlet pipe 71 with the airflow or are adsorbed into the filter screen of the air outlet pipe 71. By drawing the particles into the first inner cavity 10 through airflow, the impact of the particles on the cleanliness of the external environment is reduced.

[0038] Before entering the second through-hole 132, the airflow first flows over the surfaces of the first stator module 3 and the second stator module 4. The air exchanges heat with the first stator module 3 and the second stator module 4, cooling them down. After entering the first inner cavity 10 through the second through-hole 132, the air passes over the inner surfaces of the upper mounting plate 11 and the side mounting plate 12, where it exchanges heat again with the side mounting plate 12 before being discharged from the outlet pipe 71. During this airflow, both sides of the first stator module 3 and the second stator module 4 are cooled, lowering their temperatures and increasing the magnetic force generated by them, thereby increasing the load capacity of the magnetic actuator 2.

[0039] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
