Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, and more specifically, to a conveying system. Background Technology

[0002] In the fields of modern transportation and industrial automation, moving-magnet permanent magnet linear motors are receiving increasing attention as a novel transportation technology. Transportation systems using moving-magnet permanent magnet linear motors consist of a fixed stator and a moving rotor. The interaction between the stator and rotor causes the rotor to move linearly. For example, the rotor includes a permanent magnet that generates a constant magnetic field. The stator includes coils; when current flows through the coils, according to Ampere's law, the coils generate a magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet, causing the rotor of the motor to move linearly.

[0003] However, in practical applications, a coil winding and a permanent magnet array are usually set up for electromagnetic coupling. This setup generates a weak driving force, which is not conducive to dealing with large loads. Utility Model Content

[0010] Furthermore, the stator base has an inner cavity, and the stator assembly also includes a drive structure disposed within the inner cavity and electrically connected to the first armature winding and the second armature winding.

[0011] Furthermore, a plug-in interface is provided on the first surface so that the drive structure can be electrically connected to an external structure. The plug-in interface is located below the first armature winding, and the lower surface of the first body is higher than the plug-in interface.

[0012] Furthermore, the stator base also includes a first through hole on the first surface and a second through hole on the second surface, and the conveying system also includes a fan structure, with the air outlet of the fan structure corresponding to the first through hole or the second through hole.

[0013] Furthermore, the transmission system also includes a power supply structure, a power take-up structure, and a power consumption structure. The power supply structure is mounted on the stator base, while the power take-up structure and the power consumption structure are both mounted on the mover assembly.

The first body is configured to cooperate with the first surface, and the third body is configured to cooperate with the third surface, so that the first surface and the third surface are sandwiched between the first body and the third body.

Therefore, the technical solution of this application can effectively solve the problem of weak driving force in related technologies. Attached Figure Description

[0037] like Figures 1 to 6As shown, this application provides a conveying system. Some embodiments of the conveying system include: a stator assembly 10, a mover assembly 20, a sensor 26, and a guide structure 30. The stator assembly 10 includes a stator base 11 and a detection element 12. The stator base 11 has a first surface 111, a second surface 112, and a third surface 113. The first surface 111 and the third surface 113 are disposed opposite to each other. The second surface 112 is connected between the upper end of the first surface 111 and the upper end of the third surface 113. A first armature winding 13 is disposed on the first surface 111, and a second armature winding 14 is disposed on the third surface 113. The detection element 12 is disposed on the first surface 111 and / or the third surface 113. The mover assembly 20 includes: The assembly includes a mover body and a sensor 26. The sensor 26 is mounted on the mover body and can cooperate with the detection element 12. The mover body includes a first body 21, a second body 22, and a third body 23 connected in sequence. The first body 21 is disposed opposite to the first surface 111, the second body 22 is located above the second surface 112, and the third body 23 is disposed opposite to the third surface 113. The first body 21 is provided with a first permanent magnet array 24 electromagnetically coupled to the first armature winding 13, and the third body 23 is provided with a second permanent magnet array 25 electromagnetically coupled to the second armature winding 14. The sensor 26 is mounted on the mover assembly 20 and can cooperate with the detection element 12. The guide structure 30 is disposed between the second surface 112 and the second body 22.

[0038] Applying the technical solution of this embodiment, the stator base 11 has a first surface 111, a second surface 112, and a third surface 113. The first surface 111 and the third surface 113 are arranged opposite each other to form two opposing side surfaces. The second surface 112 connects the upper end of the first surface 111 and the upper end of the third surface 113 to form a top surface connecting the two opposing side surfaces. The mover body includes a first body 21, a second body 22, and a third body 23 connected in sequence. The second body 22 is located above the second surface 112, so that the second surface 112 supports the second body 22. The first body 21 is configured to cooperate with the first surface 111, and the third body 23 is configured to cooperate with the third surface 113, so that the first surface 111 and the third surface 113 are sandwiched between the first body 21 and the third body 23. Since the second surface 112 supports the second body 22, the mover assembly 20 can be stably supported on the stator base 11 and can move along the extension direction of the stator base 11. The guide structure 30 is disposed between the second surface 112 and the third surface 113. Between the two bodies 22, the mover assembly 20 is ensured to move along the designed path; the detection element 12 is set on the first surface 111 and / or the third surface 113, and the sensor 26 is set on the mover body and can cooperate with the detection element 12 to realize the detection of the mover assembly 20; compared with the scheme of setting a coil and a permanent magnet in related technologies, the first surface 111 is provided with a first armature winding 13, the third surface 113 is provided with a second armature winding 14, the first body 21 is provided with a first permanent magnet array 24 electromagnetically coupled to the first armature winding 13, and the third body 23 is provided with a second permanent magnet array 25 electromagnetically coupled to the second armature winding 14. Without significantly increasing the volume of the stator assembly 10 and the mover assembly 20, the number of electromagnetically coupled armature windings and permanent magnet arrays and the area of ​​electromagnetic coupling are increased, so that the mover assembly 20 can be subjected to a greater driving force, thereby enabling the mover assembly 20 to bear a greater load, greatly enhancing the conveying efficiency of the conveying system and expanding the application scenarios of the conveying system. Therefore, the technical solution of this embodiment can effectively solve the problem of weak driving force in related technologies.

[0039] In this embodiment, the number of guide structures is controlled. Only one guide structure 30 is set between the second surface 112 and the second body 22. In addition, the first surface 111 and the third surface 113 are sandwiched between the first body 21 and the third body 23, which can also ensure the stable movement of the mover assembly 20. Since no additional guide structures are set in the lateral direction, the dimensions of the stator assembly 10 and the mover assembly 20 in the lateral direction are also reduced, so that the transportation system can be thinner and lighter while still having a strong load capacity.

[0040] like Figure 5 as well as Figure 7 As shown, sensor 26 includes a first sub-sensor 261 and a second sub-sensor 262, which are disposed on the third body 23. Detection element 12 includes a first detection element 121 cooperating with the first sub-sensor 261 and a second detection element 122 cooperating with the second sub-sensor 262. Both the first detection element 121 and the second detection element 122 are disposed on the third surface 113. Specifically, by setting multiple sensors and detection elements, the effect of collecting different information from the moving parts 20 is achieved, thereby facilitating appropriate control and adjustment of the conveying system by the staff. The first sub-sensor 261 is an identification sensor, and the second sub-sensor 262 is a position sensor. Since multiple moving parts 20 are configured, the identification sensor refers to the sensor used to identify different moving parts 20. The identification sensor can be a barcode sensor, a radio frequency identification sensor, or a vision system. The barcode sensor is used to read the barcode affixed to an object to identify the object's identity or obtain information about the object. The radio frequency identification sensor identifies objects with RFID tags through wireless signals and is suitable for fast-moving objects or when visibility is obstructed. The vision system uses cameras and image processing technology to identify object features such as shape, color, and size, and can be used for more complex recognition tasks. Position sensors are used to determine the position information of the moving part 20, thereby determining its current position. Position sensors can be photoelectric sensors, magnetic encoders, proximity sensors, capacitive sensors, ultrasonic sensors, laser sensors, or Hall effect sensors. Photoelectric sensors use the emission and reception of light beams to detect the position of objects. Magnetic encoders determine position by detecting the position of magnetic materials. Proximity sensors detect whether an object is approaching. Capacitive sensors detect the position of objects by measuring changes in capacitance. Ultrasonic sensors use the emission and reception of ultrasonic waves to measure the distance to objects. Laser sensors use laser beams to accurately measure the position of objects. Hall effect sensors determine the position of objects by detecting changes in magnetic fields.

[0041] like Figure 7As shown, the third surface 113 is a vertical surface. The first detection element 121 and the second detection element 122 are respectively disposed on both sides of the second armature winding 14 in the vertical direction, and the first sub-sensor 261 and the second sub-sensor 262 are respectively disposed on both sides of the second permanent magnet array 25 in the vertical direction. Specifically, "vertical surface" refers to a vertical surface or an inclined surface with a certain angle to the vertical surface. The angle between the inclined surface and the vertical surface can be between 0 and 15°. The first detection element 121 and the second detection element 122 are arranged at intervals in the vertical direction, and the first sub-sensor 261 and the second sub-sensor 262 are arranged at intervals in the vertical direction, so as not to increase the size of the stator assembly 10 and the mover assembly 20 in the horizontal direction, making it easier to set up multiple sensors and multiple detection elements. Furthermore, since the first sub-sensor 261 and the second sub-sensor 262 are respectively located on both sides of the second permanent magnet array 25 in the vertical direction, it can be ensured that there is a certain distance between the first sub-sensor 261 and the second sub-sensor 262 and they will not interfere with each other, thereby ensuring the reliability of the first sub-sensor 261 and the second sub-sensor 262.

[0042] like Figure 8 As shown, sensor 26 includes a third sub-sensor 263 and a fourth sub-sensor 264. The third sub-sensor 263 is disposed on the first body 21, and the fourth sub-sensor 264 is disposed on the third body 23. Detection element 12 includes a third detection element 123 that cooperates with the third sub-sensor 263 and a fourth detection element 124 that cooperates with the fourth sub-sensor 264. The third detection element 123 is disposed on the first surface 111, and the fourth detection element 124 is disposed on the third surface 113. Specifically, by disposing the sensor and detection element on two opposing surfaces (first surface 111 and third surface 113) or two bodies (first body 21 and third body 23), the surface area of ​​the two surfaces or two bodies can be utilized more fully, thereby ensuring the miniaturization of the overall volume of the conveying system.

[0043] like Figure 3 As shown, the guide structure 30 includes a guide rail 31 and a slider 32. The guide rail 31 is disposed on the second surface 112, and the slider 32 is disposed on the second body 22. One of the guide rail 31 and the slider 32 is provided with a plug-in portion 311, and the other of the guide rail 31 and the slider 32 is provided with a slot 321. The plug-in portion 311 can be inserted into the slot 321. Specifically, the guide rail 31 and the slider 32 have the advantages of simple structure, stable fit, and easy processing. The guide rail 31 is provided with a plug-in portion 311, and the slider 32 is provided with a slot 321. In addition, the fit between the plug-in portion 311 and the slot 321 enables the guide structure 30 to limit the movement component 20 in the lateral direction, thereby enabling the movement component 20 to move along a preset path without deviation.

[0044] like Figure 3 As shown, slot 321 includes a first slot segment 322 and a second slot segment 323 that are interconnected. The second slot segment 323 is positioned relative to the first slot segment 322 near the bottom wall of slot 321. The width of the first slot segment 322 is smaller than the width of the second slot segment 323. The insertion part 311 includes a first insertion segment 312 and a second insertion segment 313. The first insertion segment 312 is adapted to the first slot segment 322, and the second insertion segment 313 is adapted to the second slot segment 323. Specifically, by setting the first slot segment 322 and the second slot segment 323 with different slot widths, after slot 321 and insertion part 311 are inserted and slidably engaged, insertion part 311 will not detach from slot 321, thus preventing detachment. This further ensures that the mover assembly 20 will not detach from stator assembly 10 during movement, thereby ensuring the safety of the conveying system.

[0045] like Figure 2 as well as Figure 4 As shown, the stator base 11 has an inner cavity 114, and the stator assembly 10 also includes a drive structure 15. The drive structure 15 is disposed within the inner cavity 114 and electrically connected to the first armature winding 13 and the second armature winding 14. Specifically, the drive structure 15 is typically a control board, which (usually called a control unit or controller) is the core component responsible for managing the operation of the entire conveying system. It receives input signals from sensors, processes these signals, and controls the operating state of each component of the conveying system according to a preset program or algorithm. For example, it can control the energization of the first armature winding 13 and the second armature winding 14. The control board ensures that the conveying system operates according to a predetermined path, speed, and schedule, while maintaining the stability and accuracy of the conveying system.

[0046] like Figure 2 as well as Figure 4 As shown, a connector 16 is provided on the first surface 111 to enable the drive structure 15 to be electrically connected to an external structure. The connector 16 is located below the first armature winding 13, and the lower surface of the first body 21 is higher than the connector 16. Specifically, the connector 16 is electrically connected to the drive structure 15 to enable the drive structure 15 to be electrically connected to an external structure. The connector 16 is located below the first armature winding 13, and the lower surface of the first body 21 is higher than the connector 16, so that when a wire is plugged into the connector 16, the wire will not interfere with the first body 21.

[0047] like Figure 1 , Figure 2 as well as Figure 4As shown, the stator base 11 also includes a first through hole 115 on the first surface 111 and a second through hole 116 on the second surface 112. The conveying system also includes a fan structure, with the fan outlet corresponding to either the first through hole 115 or the second through hole 116. Specifically, the fan structure is an axial fan, and the fan structure's corresponding arrangement with the first through hole 115 or the second through hole 116 allows the airflow generated by the fan structure to enter the inner cavity 114 through the first through hole 115 or the second through hole 116 or be drawn out of the inner cavity 114, thereby achieving heat dissipation for the drive structure 15. Furthermore, the fan outlet is positioned directly opposite the through hole to better facilitate airflow within the inner cavity 114, resulting in improved heat dissipation.

[0048] like Figure 9 As shown, the conveying system also includes a power supply structure 40, a power take-up structure 50, and a power consumption structure 60. The power supply structure 40 is mounted on the stator base 11. The power take-up structure 50 and the power consumption structure 60 are both mounted on the mover assembly 20. The power take-up structure 50 and the power supply structure 40 are slidably coupled. When sliding, the power take-up structure 50 can maintain an electrical connection with the power supply structure 40 to supply power to the power consumption structure 60. Specifically, the power consumption structure 60 can be an energy storage structure or a structure that converts electrical energy into mechanical energy. The power take-up structure 50 can be a brush structure, and the power supply structure 40 can be a charged wire structure. The brush structure and the wire structure are in contact to realize the transmission of electrical energy. The brush structure can also move synchronously with the mover assembly 20 and maintain electrical contact with the wire structure.

[0049] like Figure 9 As shown, the power-taking structure 50 includes a main body 51 and a positive terminal 52 and a negative terminal 53 connected to the main body 51. The positive terminal 52 and the negative terminal 53 are spaced apart. The power-giving structure 40 includes a first conductive channel 41 and a second conductive channel 42. The positive terminal 52 is inserted into the first conductive channel 41, and the negative terminal 53 is inserted into the second conductive channel 42. Specifically, both the first conductive channel 41 and the second conductive channel 42 are provided with wire structures so that the positive terminal 52 and the negative terminal 53 can respectively make electrical contact with the corresponding wire structures.

[0050] Furthermore, in some embodiments, there are multiple mover assemblies 20, each including a first mover and a second mover. A power-taking structure 50 and a power-consuming structure 60 are disposed on the first mover. A power transmission structure is provided between the first and second movers to transfer the electrical energy obtained by the power-taking structure 50 from the first mover to the second mover. The power transmission structure includes an excitation cable and a coupling coil. The excitation cable is disposed on the first mover and electrically connected to the power-consuming structure 60. The coupling coil is disposed on the second mover and is electromagnetically coupled to the excitation cable. The excitation cable generates alternating current to enable the coupling coil to generate electrical energy. Specifically, the mover assembly 20 only needs to supply power to the power-consuming structure 60 (e.g., the actuating structure) when it is in a specific area or at a specific workstation, so that the actuator can assist the external structure in processing the workpiece. Therefore, on the one hand, by only setting the power supply structure 40 on certain stator bases 11, the length of the power supply structure 40 can be reduced, thereby lowering costs. On the other hand, when the installation space is limited and insufficient to set a long power supply structure 40, or when the workstation requires that the power supply structure 40 cannot be set, the second mover receives power through the first mover to achieve the effect of powering the actuator. The coupling coil can be electromagnetically coupled with the excitation cable, and AC current is generated to the excitation cable through the power supply structure 60, thereby causing the coupling coil to generate electrical energy, which in turn powers the second mover.

[0051] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0052] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures.
