Description

Technical Field

[0001] This application relates to the field of conveyor technology, and in particular to a motor conveying device. Background Technology

[0002] Magnetic drive conveyor lines have the advantages of high flexibility, high speed and high precision, and can replace traditional belt conveyors, chain drives and other conveyor systems in some fields.

[0003] In related technologies, magnetic drive conveyor lines include a stator and a mover. The stator can provide driving force to the mover, which usually carries the workpiece to be processed.

[0004] During the conveying process, if the mover experiences slight offset or eccentricity due to steering force or external impact, the coupling surface of the mover will decrease and the driving force will be reduced. With reduced driving force, the constraint of the stator on the mover becomes weaker, which may lead to further eccentricity of the mover, causing it to sway or overturn, posing a risk of the workpiece falling off, and thus affecting the stability of the conveying process. Utility Model Content

[0005] This application provides a motor-driven conveying device to reduce the probability of workpieces falling, thereby improving the stability and reliability of the conveying process.

[0006] This application provides a motor conveying device, comprising: a mover, including a mover body and a permanent magnet array, a first roller, and a second roller connected to the mover body; a stator, including a stator base and an armature winding, wherein a receiving cavity is formed inside the stator base, and the stator base is provided with at least one conveying channel communicating with the receiving cavity, the armature winding, the permanent magnet array, and the second roller are all located within the receiving cavity, and the first roller is located outside the receiving cavity; when the stator is a linear stator, a first guide path is formed within the receiving cavity, the first roller abuts against the stator base, and the second roller is suspended within the first guide path; and / or, when the stator is an arc stator or a commutated stator, a second guide path is formed outside the receiving cavity on the stator base, the first roller is suspended within the second guide path, and the second roller abuts against the stator base or the armature winding.

[0007] In some embodiments, the first guide path and the second guide path are both recessed grooves, and the depth of the first guide path and the second guide path is greater than or equal to 1 mm and less than or equal to 3 mm.

[0008] In some embodiments, the moving body includes a first body, a second body, and a guide portion connecting the first body and the second body. The first body is located outside the receiving cavity, the guide portion passes through the conveying channel, the second body is located inside the receiving cavity, the first roller is connected to the first body, and both the permanent magnet array and the second roller are connected to the second body.

[0009] In some embodiments, there are multiple first rollers, which are evenly distributed on opposite sides of the first body in the width direction of the conveying channel; there are multiple second rollers, which are evenly distributed on opposite sides of the second body in the width direction of the conveying channel; wherein the distance between two oppositely arranged first rollers is smaller than the distance between two oppositely arranged second rollers.

[0010] In some embodiments, the two sidewalls of the guide portion along the width direction of the conveying channel are guide surfaces, and the closer to the center of the guide surface, the closer the distance between the two guide surfaces.

[0011] In some embodiments, the moving body further includes a mounting portion connecting the first body and the second body. There are two mounting portions spaced apart along the extension direction of the conveying channel. The guide portion is located between the two mounting portions. The mounting portion includes: a shaft, the two ends of which are fixedly connected to the first body and the second body respectively; and a plurality of bearings sleeved on the shaft.

[0012] In some embodiments, the armature winding is disposed at least one of the cavity bottom, side wall, and cavity top of the receiving cavity, and the permanent magnet array is disposed opposite to the armature winding.

[0013] In some embodiments, the stator base includes a base plate, a side plate, and a cover plate connected in sequence, the base plate, the side plate, and the cover plate together forming the receiving cavity, and the conveying channel is disposed on the cover plate, wherein:

[0014] The stator is a linear stator, the first guide path is formed on the side surface of the armature winding near the cover plate, or the first guide path is formed on the side surface of the substrate near the cover plate, and the first roller abuts against the side surface of the cover plate away from the substrate.

[0015] Alternatively, the stator is an arc stator, the second guide path is formed on the side surface of the cover plate away from the substrate, the second roller abuts against the side surface of the armature winding near the cover plate, or the second roller abuts against the side surface of the substrate near the cover plate.

[0016] In some embodiments, the stator is a commutating stator, and there are multiple transport channels extending from the same end in different directions. The second guide path is formed on the side surface of the cover plate away from the substrate. The second guide path includes multiple sub-guide paths, each of which is disposed on both sides of a corresponding transport channel along its width direction. The first roller is correspondingly suspended in one of the sub-guide paths. The second roller abuts against the side surface of the armature winding near the cover plate, or the second roller abuts against the side surface of the substrate near the cover plate.

[0017] In some embodiments, the conveying channel includes a first conveying channel and a second conveying channel extending from the same end, wherein the first conveying channel extends in a straight line or an arc direction, and the second conveying channel extends in an arc direction;

[0018] The second guide path is formed on the side surface of the cover plate opposite to the substrate. The second guide path includes a first sub-guide path and a second sub-guide path. The first sub-guide path is located on both sides of the first conveying channel along its width direction. The second sub-guide path is located on both sides of the second conveying channel along its width direction. The first roller is suspended in the first sub-guide path or the second sub-guide path.

[0019] In some embodiments, the stator further includes a switching component connected to the stator base. The switching component is used to guide the mover to move along the first conveying channel or along the second conveying channel. The switching component includes: a driving member connected to the cover plate; and a blocking member connected to the output end of the driving member. The driving member is used to drive the blocking member to move between a first position and a second position.

[0020] When the blocking member is in the first position, the blocking member blocks the second conveying channel, and the blocking member abuts against the moving body to guide the moving body to run along the first conveying channel; when the blocking member is in the second position, the blocking member blocks the first conveying channel, and the blocking member abuts against the moving body to guide the moving body to run along the second conveying channel.

[0021] In some embodiments, the first conveying channel extends in a straight line direction, and the second conveying channel extends in an arc direction;

[0022] The blocking member has a first abutting surface and a second abutting surface disposed opposite to each other along the width direction of the first conveying channel. The second abutting surface is located on the side of the first abutting surface away from the second conveying channel. At least a portion of the first abutting surface is an arc surface, and the second abutting surface is a plane.

[0023] In this application, the mover body is provided with a first roller and a second roller. The first roller is located outside the receiving cavity, and the second roller is located inside the receiving cavity. When the mover is conveyed on the conveying channel of the linear stator, a first guide path is formed inside the receiving cavity. The first roller abuts against the part of the stator base located outside the receiving cavity, and the second roller is suspended within the first guide path. The mover is not affected by steering forces, and the weight of both the mover and the workpiece is supported by the first roller. The mover moves forward in a straight line under the support of the first roller. Even if the mover is impacted by external forces, the first roller near the center of gravity can still abut against the stator base to provide stable support for the mover body and suppress its eccentricity and swaying. At the same time, since the second roller is suspended within the first guide path, when the tilt angle of the mover body is large, the second roller can abut against the side wall of the first guide path. The first guide path can also further limit the second roller in its width, thereby further suppressing the eccentricity and swaying of the mover.

[0024] When the mover moves from a linear stator to a curved stator or a commutated stator, it experiences a steering force from the curved stator or a switching force from the commutated stator, which can cause eccentricity and wobbling. When the mover wobbles, the second roller, being closer to the permanent magnet array, can better suppress the bias or tilt of the permanent magnet array, ensuring a more stable coupling force between the permanent magnet array and the armature winding, thus ensuring a more stable coupling force on the mover. Based on ensuring a stable coupling force on the mover, the coupling force can be increased by increasing the current, making the mover's operation more stable and preventing wobbling or tipping. Furthermore, when the mover wobbles, the second roller, being closer to the permanent magnet array, can quickly contact the stator base or armature winding within the housing cavity. In this situation, the second roller provides stable support. Because of its proximity to the permanent magnet array, the second roller can suppress the wobbling and offset of the permanent magnet array, thereby suppressing the eccentricity and wobbling of the mover. Meanwhile, since the first roller is suspended within the second guide path, when the mover has a large tilt angle, the first roller can abut against the side wall of the second guide path, and the second guide path can further limit the first roller in its width, thereby further suppressing the eccentricity and sway of the mover.

[0025] This ensures the stable operation of the mover on any stator's conveying channel, reduces the probability of mover eccentricity caused by external impacts, steering forces, switching forces, etc., and thus helps improve the stability and reliability of mover conveying.

[0046] As described in the background section, magnetically driven conveyor lines have replaced traditional belt conveyors, chain drives, and other conveyor systems in some fields due to their advantages of high flexibility, high speed, and high precision.

[0047] A conveyor line consists of a stator and a mover. The stator provides driving force to the mover, which typically carries the workpiece to be processed. During transport, if the mover experiences slight misalignment or eccentricity due to turning forces or external impacts, the coupling surface of the mover will decrease, reducing the driving force. With reduced driving force, the constraint of the stator on the mover weakens, potentially leading to further eccentricity of the mover. This can cause the mover to wobble or overturn, posing a risk of workpiece falling and ultimately affecting the stability of the conveyor.

[0048] To address the aforementioned problems, this application proposes a motor-driven conveying device to reduce the probability of workpieces falling, thereby improving the stability and reliability of the conveying process.

[0049] like Figure 1 and Figure 2 As shown, the motor conveying device 10 includes a stator 100 and a mover 200. The mover 200 includes a mover body 210, a permanent magnet array 220, a first roller 230, and a second roller 250 connected to the mover body 210. The stator 100 includes a stator base 110 and an armature winding 120. A receiving cavity 101 is formed inside the stator base 110. The stator base 110 is provided with at least one conveying channel 11 communicating with the receiving cavity 101. The armature winding 120, the permanent magnet array 220, and the second roller 250 are all disposed inside the receiving cavity 101, and the first roller 230 is located outside the receiving cavity 101.

[0050] like Figure 3 As shown, when the stator 100 is a linear stator 100a, a first guide path 1011 is formed in the receiving cavity 101, the first roller 230 abuts against the stator base 110, and the second roller 250 is suspended in the first guide path 1011. In this embodiment, the linear stator 100a refers to a linear stator whose armature winding extends in a straight line, and whose transport channel also extends in a straight line. When the mover is transported on the linear stator, the mover's trajectory is a straight line.

[0051] like Figure 4 and Figure 5 As shown, when the stator 100 is an arc stator 100b or a commutating stator 100c, the stator base 110 is located outside the receiving cavity 101 and forms a second guide path 1012. The first roller 230 is suspended within the second guide path 1012, and the second roller 250 abuts against the stator base 110 or the armature winding 120. In this embodiment, the arc stator 100b refers to a stator 100b whose armature winding extends in an arc shape, and whose transport channel also extends in an arc shape. This arc can be a circular arc with a constant radius, a circular arc with a non-constant radius, or a curved arc. This embodiment does not limit the specific shape of the arc. It should be noted that when the mover is transported on the arc stator 100b, the mover's trajectory is the same as the arc. Furthermore, in other embodiments, the stator may also be a commutated stator 100c, the armature winding of the commutated stator 100c having multiple extending directions to drive the mover to move along different transport directions; and further, the commutated stator 100c having multiple transport channels, different transport channels having different extending directions, and when the mover is in different transport channels, the transport direction of the mover is also different. Among the multiple extending directions of the armature winding of the commutated stator 100c, at least one extending direction is arc-shaped.

[0052] In this application, the stator 100 of the motor conveying device 10 can be multiple, and the stator 100 of the motor conveying device 10 can be spliced ​​to form a conveying line. The number of movers 200 can be one or multiple.

[0053] The motor conveying device 10 includes a stator 100 and a mover 200. The mover 200 can move relative to the stator 100 under the magnetic drive of the stator 100, thereby realizing the function of the mover 200 of the motor conveying device 10 conveying the workpiece 400.

[0054] Please refer to Figures 1 to 5 The stator base 110 serves as the base of the stator 100, and various components of the stator 100 can be mounted on the stator base 110. An accommodating cavity 101 is formed inside the stator base 110, within which the armature winding 120, the permanent magnet array 220 on the mover 200, and the second roller 250 are all housed. The armature winding 120 is a magnetic field generating component, capable of generating a magnetic field when energized. The permanent magnet array 220 is a force-bearing component, composed of multiple permanent magnets arranged according to a specific polarization direction, forming a continuous or spaced magnetic pole structure. The permanent magnet array 220 and the armature winding 120 are magnetically coupled within the accommodating cavity 101. The permanent magnet array 220 generates a driving force under the influence of the magnetic field of the armature winding 120, thereby driving the mover body 210 to move along the conveying channel 11.

[0055] This configuration, on the one hand, improves the magnetic coupling effect between the armature winding 120 and the permanent magnet array 220, thereby improving conveying efficiency. On the other hand, installing both within the receiving cavity 101 of the stator base 110 allows for a concealed design. This reduces the probability of foreign objects entering the receiving cavity 101, thereby reducing the probability of particulate matter adsorbing onto the armature winding 120 and the permanent magnet array 220 during excitation, and reducing the probability of contamination of the armature winding 120 and the permanent magnet array 220 by impurities, thus improving conveying reliability and further increasing conveying efficiency. Furthermore, it also helps reduce the volume of the mover 200 and the stator 100, thereby facilitating the miniaturization of the motor conveying device 10.

[0056] The connection between the conveying channel 11 and the receiving cavity 101 means that the conveying channel 11 does not have a bottom, but only has two oppositely arranged side walls. The conveying channel 11 is in a through state, and the conveying channel 11 can realize the connection between the receiving cavity 101 and the outside world.

[0057] The first roller 230 is located outside the receiving cavity 101, and the second roller 250 is located inside the receiving cavity 101, both connected to the mover body 210. That is, a portion of the mover body 210 is located inside the receiving cavity 101, and another portion passes through the conveying channel 11 and is located outside the receiving cavity 101. The permanent magnet array 220 and the second roller 250 are connected to the portion of the mover body 210 located inside the receiving cavity 101, while the first roller 230 is connected to the portion of the mover body 210 located outside the receiving cavity 101. This arrangement, on the one hand, reduces the volume of the receiving cavity 101, thereby reducing the space occupied by the stator 100 and achieving stator miniaturization. Secondly, it allows for a more rational arrangement of the structural relationships in the spatial height dimension, with only a portion of the mover body 210 exposed, thus helping to reduce the space occupied by the mover 200. Therefore, it is beneficial to further meet the miniaturization requirements of the motor conveying device 10.

[0058] Stator 100 can be a linear stator 100a, a curved stator 100b, or a commutating stator 100c. Please refer to [reference needed]. Figure 3 When the conveying channel 11 of the stator 100 is a straight line, the stator 100 is a straight stator 100a; please refer to Figure 4 When the conveyor channel 11 is curved, the stator 100 is a curved stator 100b. Please refer to [reference needed]. Figure 5 When the stator 100 is provided with multiple conveying channels 11 with different conveying directions and can drive the mover 200 to move along one of the conveying channels 11, the stator 100 is a commutating stator 100c.

[0059] Please refer to Figure 8 The first roller 230 is suspended within the second guide path 1012, where "suspended" means that the first roller 230 is located within the second guide path 1012 but does not contact the second guide path 1012; or, the second roller 250 is suspended within the first guide path 1011, where "suspended" means that the second roller 250 is located within the first guide path 1011 but does not contact the first guide path 1011.

[0060] In this application, when the mover 200 is conveyed on the conveying channel 11 of the linear stator 100a, a first guide path 1011 is formed in the receiving cavity 101 of the linear stator 100a, the first roller 230 abuts against the part of the stator base 110 located outside the receiving cavity 101, and the second roller 250 is suspended in the first guide path 1011.

[0061] When the mover 200 carries the workpiece 400, the mover 200 and the workpiece 400 can be considered as a whole. Since the workpiece 400 and part of the mover body 210 are respectively located on both sides of the first roller 230, and the distance between the workpiece 400 and the first roller 230 is relatively small, the center of gravity of the whole can be considered to be located approximately at the first roller 230. When the mover 200 is conveyed on the linear stator 100a, the mover 200 is not affected by the steering force. The weight of the mover 200 and the workpiece 400 are both supported by the first roller 230, and the mover 200 moves forward in a straight line under the support of the first roller 230. In this embodiment, the first roller 230 is set to abut against the part of the surface of the stator base 110 located outside the receiving cavity 101. Even if the mover 200 is impacted by an external force, the first roller 230 near the center of gravity can still abut against the stator base 110 to provide stable support for the mover body 210 and suppress its eccentricity and swaying. Meanwhile, since the second roller 250 is suspended within the first guide path 1011, when the tilt angle of the mover body 210 is large, the second roller 250 can abut against the side wall of the first guide path 1011. The first guide path 1011 can also further limit the second roller 250 in its width, thereby further suppressing the eccentricity and sway of the mover 200.

[0062] Furthermore, it should be noted that the second roller 250 is suspended within the first guide path 1011, meaning there is a gap between the second roller 250 and the first guide path 1011. Given the rolling connection between the first roller 230 and the stator base 110, if the second roller 250 also rolls with the first guide path 1011, then higher precision in fit, installation, and machining between the moving and stators is required to ensure that both the first roller 230 and the second roller 250 simultaneously engage with the stator 100. This embodiment of the application, by suspending the second roller 250 within the first guide path 1011, reduces the precision in fit, installation, and machining between the moving element 200 and the stator 100, thereby reducing costs while ensuring stable conveying.

[0063] When the mover 200 moves from the linear stator 100a to the curved stator 100b or the commutating stator 100c, the mover 200 will be subjected to the steering force of the curved stator 100b or the switching force of the commutating stator 100c, which may cause the mover 200 to become eccentric and wobble. The steering force or switching force on the mover 200 originates from the armature winding 120. Because the armature winding 120 is coupled to the permanent magnet array 220, and the extension direction of the armature winding 120 changes, the direction of the coupling force between the permanent magnet array 220 and the armature winding 120 changes. During this change in the direction of the coupling force, the movement path of the mover 200 is curved. When the speed of the mover 200 is too high or the load on the workpiece 400 is large, the mover 200 may be in an eccentric state, resulting in wobble or tipping. Since the second roller 250 is closer to the stator base 110 or armature winding 120, when the mover 200 shakes, the permanent magnet array 220 is biased or tilted relative to the armature winding 120, which makes the coupling force between the permanent magnet array 220 and the armature winding 120 unstable, which will further cause the mover 200 to shake or overturn.

[0064] In this embodiment, by setting a second roller 250 to roll into contact with the stator base 110 or armature winding 120 within the receiving cavity 101, when the mover 200 shakes, the second roller 250, being closer to the permanent magnet array 220, can better suppress the bias or tilt of the permanent magnet array 220, thus ensuring a more stable coupling force between the permanent magnet array 220 and the armature winding 120, thereby ensuring a more stable coupling force on the mover 200. Based on ensuring a stable coupling force on the mover 200, the coupling force on the mover 200 can be increased by increasing the current, making the operation of the mover 200 more stable and preventing shaking or tipping of the mover 200. Furthermore, when the mover 200 shakes, because the second roller 250 is closer to the permanent magnet array 220, it can quickly abut against the stator base 110 or armature winding 120 within the receiving cavity 101. In this configuration, the second roller 250 provides stable support. Because the second roller 250 is close to the permanent magnet array 220, it can suppress the swaying and offset of the permanent magnet array 220, thereby suppressing the eccentricity and swaying of the mover 200. Simultaneously, since the first roller 230 is suspended within the second guide path 1012, when the mover 200 has a large tilt angle, the first roller 230 can abut against the side wall of the second guide path 1012. The second guide path 1012 can further limit the first roller 230 in its width, thereby further suppressing the eccentricity and swaying of the mover 200.

[0065] Therefore, the stable operation of the mover 200 on the conveying channel 11 of any stator 100 can be guaranteed, reducing the probability of the mover 200 being eccentric due to external impacts, turning forces, switching forces and other forces, thereby improving the stability and reliability of the mover 200 conveying.

[0066] In some embodiments, the first guide path 1011 and the second guide path 1012 are both recessed grooves, and the depth of the first guide path 1011 and the second guide path 1012 is greater than or equal to 1 mm and less than or equal to 3 mm.

[0067] This design has two advantages. First, the shallow depth of the recess minimizes space usage, thus facilitating the miniaturization of the stator 100. Second, the shallow depth allows the first roller 230 to contact the side or bottom of the second guide path 1012, or the second roller 250 to contact the side or bottom of the first guide path 1011, when the mover 200 is eccentric or wobbles significantly. In this case, the first roller 230 and the second roller 250 can jointly support the mover 200, better preventing it from tipping over. This further improves the stability and reliability of the workpiece 400 transport.

[0068] In some embodiments, such as Figure 2 As shown, the mover body 210 includes a first body 211, a second body 212, and a guide portion 214 connecting the first body 211 and the second body 212. The first body 211 is located outside the receiving cavity 101, and the guide portion 214 is used to pass through the conveying channel 11. The second body 212 is located inside the receiving cavity 101. The first roller 230 is connected to the first body 211, and the permanent magnet array 220 and the second roller 250 are both connected to the second body 212. The guide portion 214 can abut against the groove wall of the conveying channel 11, so that the guide portion 214 limits the movement of the mover 200 along the conveying path under the limiting action of the conveying channel 11.

[0069] This achieves the installation and fixation of the first roller 230, the permanent magnet array 220, and the second roller 250 on the mover body 210. Firstly, it reduces the volume of the receiving cavity 101, thereby reducing the space occupied by the stator 100 and achieving stator miniaturization. Secondly, it allows for a more rational arrangement of the structural positions in the spatial height dimension, with only the first body 211 of the mover body 210 exposed, thus helping to reduce the space occupied by the mover 200. This, in turn, facilitates further miniaturization of the motor conveying device 10.

[0070] In some embodiments, such as Figure 2As shown, there are multiple first rollers 230, which are evenly distributed on opposite sides of the first body 211 in the width direction of the conveying channel 11. This arrangement helps to improve the load-bearing capacity and load-bearing stability of the first rollers 230.

[0071] In some embodiments, such as Figure 2 As shown, there are multiple second rollers 250, which are evenly distributed on opposite sides of the second body 212 in the width direction of the conveying channel 11. This arrangement helps to improve the load-bearing capacity and load-bearing stability of the second rollers 250.

[0072] Furthermore, such as Figure 2 As shown, the distance between two oppositely arranged first rollers 230 is smaller than the distance between two oppositely arranged second rollers 250. "Oppositely arranged" means that the distance between two first rollers 230 or two second rollers 250 directly opposite each other on both sides of the conveying direction is smaller than the distance between two coaxial first rollers 230 on both sides of the conveying direction. It can be understood that the second rollers 250 are mainly used to suppress the eccentricity and swaying of the mover 200 caused by steering forces, switching forces, etc. Setting a larger distance between the second rollers 250 on different sides is equivalent to the second rollers 250 having a wider support area. A wider support area can better suppress the tilting of the mover 200, thus improving the anti-swaying effect of the second rollers 250 on the mover 200. As for the first roller 230, the first roller 230 only plays a load-bearing role when the stator 100 is a linear stator 100a. Setting the spacing between the first rollers 230 to be small is beneficial to achieving the miniaturization requirement of the mover 200.

[0073] In some embodiments, such as Figure 2 As shown, the first body 211 has receiving grooves 2111 on opposite sides of the conveying channel 11 in the width direction for accommodating the first roller 230.

[0074] Therefore, firstly, the first roller 230 can be protected by the groove wall of the receiving groove 2111, which reduces the exposed part of the first roller 230, thereby improving the reliability and cleanliness of the first roller 230's operation. Secondly, the first roller 230 can be embedded, making the appearance of the first body 211 after installing the first roller 230 more aesthetically pleasing and neat. At the same time, it can also reduce the external space occupied by the first roller 230, reduce the volume of the first body 211, and thus further reduce the volume of the mover 200 to meet the miniaturization requirements of the mover 200.

[0075] Optionally, the outermost surface of the first roller 230 may be flush with the first body 211.

[0076] In some embodiments, such as Figure 2 As shown, the two side walls of the guide section 214 along the width direction of the conveying channel 11 are guide surfaces 2141. The closer to the center of the guide surface 2141, the closer the distance between the two guide surfaces 2141.

[0077] This configuration serves two purposes. First, when the mover 200 is conveyed on the linear stator 100a, the front and rear sides of the guide surface 2141 can contact the groove wall of the linear conveying channel 11, thereby improving conveying stability. Second, when the mover 200 turns on the curved stator 100b or reverses on the commutating stator 100c, the guide surface 2141 can abut against the groove wall of the curved conveying channel 11, increasing the contact area between the guide surface 2141 and the curved groove wall, thus improving the stability of the limiting mechanism and, consequently, the stability of the mover 200 during commutation and turning. Furthermore, since both guide surfaces 2141 are curved guide surfaces, compared to linear guide surfaces, the turning radius of the mover 200 during turns can be reduced. That is, the contact position between the guide surface 2141 and the curved groove wall is closer to the center surface of the mover 200. By reducing the turning radius of the mover 200, the miniaturization of the commutating stator 100c and the curved stator 100b can be achieved.

[0078] In some embodiments, such as Figure 2 As shown, the moving body 210 also includes a mounting part 213 connecting the first body 211 and the second body 212. There are two mounting parts 213, which are spaced apart along the extension direction of the conveying channel 11. The guide part 214 is located between the two mounting parts 213. The mounting part 213 includes a shaft 2131 and a plurality of bearings 2132. The two ends of the shaft 2131 are fixedly connected to the first body 211 and the second body 212 respectively, and the plurality of bearings 2132 are sleeved on the shaft 2131.

[0079] By providing two mounting parts 213, each mounting part 213 including a shaft 2131 and a bearing 2132, when the mover 200 changes direction or turns, multiple bearings 2132 first roll into contact with the groove wall of the conveying channel 11, which helps to reduce the impact force when the mover 200 collides, thereby reducing the probability of damage to the mover 200. The rolling contact also allows the mover 200 to complete the change of conveying direction more smoothly.

[0080] In some embodiments, such as Figure 3 , Figure 4 , Figure 5As shown, the armature winding 120 is disposed at least one of the cavity bottom 1013, cavity top 1014, and side wall 1015 of the receiving cavity 101, and the permanent magnet array 220 is disposed opposite to the armature winding 120. This arrangement allows for magnetic coupling between the armature winding 120 and the permanent magnet array 220 at different positions within the receiving cavity 101 of any type of stator 100, thereby improving the convenience and flexibility of arranging the armature winding 120 and the permanent magnet array 220 within the receiving cavity 101.

[0081] It should be noted that the number of sidewalls 1015 of the receiving cavity 101 is multiple and distributed at least on both sides of the conveying channel 11 in the width direction. The number of sidewalls 1015 is flexibly set according to the shape and type of the stator 100. The following describes the number of sidewalls and the arrangement of the armature winding 120 for different stator types through several embodiments.

[0082] like Figure 3 As shown, in the linear stator 100a, there are two sidewalls 1015 arranged opposite to each other, and both sidewalls 1015 are planar sidewalls extending in a straight direction. At this time, the armature winding 120 can be arranged on the two sidewalls, and at least one of the cavity bottom 1013 and cavity top 1014.

[0083] like Figure 4 As shown, in the arc stator 100b, if the overall outer contour of the arc stator 100b is approximately rectangular, the number of sidewalls 1015 is three, namely the first sidewall 1015a, the second sidewall 1015b and the third sidewall 1015c. The first sidewall 1015a and the second sidewall 1015b are planar sidewalls that are spliced ​​together and are located on one side of the conveying channel 11, while the third sidewall 1015c can be a planar sidewall or an arc sidewall, which is located on the other side of the conveying channel 11. The armature winding 120 can be disposed on the three sidewalls and at least one of the cavity bottom 1013 and the cavity top 1014.

[0084] Alternatively, if the overall external contour of the arc stator 100b is roughly arc-shaped, then there are two sidewalls 1015 arranged opposite each other. Both sidewalls 1015 are arc-shaped sidewalls extending along the arc direction. The armature winding 120 can be arranged on the two sidewalls, as well as at least one of the cavity bottom 1013 and cavity top 1014.

[0085] like Figure 5 and Figure 9As shown, in the commutating stator 100c, there are two transport channels 11, namely the first transport channel 102 and the second transport channel 103, wherein the second transport channel 103 is an arc-shaped channel. At this time, there are three sidewalls 1015, namely the fourth sidewall 1015d, the fifth sidewall 1015e, and the sixth sidewall 1015f. The fourth sidewall 1015d is located on one side of the first transport channel 102, and a portion of the fifth sidewall 1015e and a portion of the sixth sidewall 1015f are located on the other side of the first transport channel 102; the fifth sidewall 1015e is located on one side of the second transport channel 103, and a portion of the sixth sidewall 1015f and a portion of the fourth sidewall 1015d are located on the other side of the second transport channel 103. The armature winding 120 can also be disposed on the three sidewalls, and at least one of the cavity bottom 1013 and the cavity top 1014.

[0086] The above is only an illustrative example. The specific arrangement of the coupling between the armature winding 120 and the permanent magnet array 220 in the receiving cavity 101 can be flexibly varied according to the type, shape, number of transport channels 11, extension direction, etc. of the stator 100. This application does not impose any restrictions on this.

[0087] In some embodiments, such as Figures 3 to 5 As shown, the stator base 110 includes a base plate 111, a side plate 113 and a cover plate 112 connected in sequence. The base plate 111, the side plate 113 and the cover plate 112 together form a receiving cavity 101, and the conveying channel 11 is provided on the cover plate 112.

[0088] It should be noted that the side wall 1015 of the receiving cavity 101 can be regarded as the side wall surface of the side plate 113 near the receiving cavity 101, the cavity bottom 1013 of the receiving cavity 101 can be regarded as the side surface of the substrate 111 near the cover plate 112, and the cavity top 1014 of the receiving cavity 101 can be regarded as the side surface of the cover plate 112 near the substrate 111.

[0089] Furthermore, such as Figure 3 As shown, the stator 100 is a linear stator 100a, the conveying channel 11 extends in a straight direction, the first guide path 1011 is formed on the side surface of the armature winding 120 near the cover plate 112, or the first guide path 1011 is formed on the side surface of the substrate 111 near the cover plate 112, the first roller 230 abuts against the side surface of the cover plate 112 away from the substrate 111, and the second roller 250 is suspended in the first guide path 1011.

[0090] This embodiment proposes a method for forming the first guide path 1011 and a method for supporting the first roller 230 when the stator 100 is a linear stator 100a. Specifically, since the armature winding 120 is located inside the receiving cavity 101, it can be located at the bottom 1013, the top 1014, or the side wall 1015 of the receiving cavity 101. Therefore, when the armature winding 120 is not located at the bottom 1013 of the receiving cavity 101, the first guide path 1011 can be formed on the side surface of the substrate 111 near the cover plate 112; when the armature winding 120 is located at the bottom 1013 of the receiving cavity 101, the first guide path 1011 can be formed on the side surface of the armature winding 120 near the cover plate 112, and the first roller 230 is supported on the side surface of the cover plate 112 away from the substrate 111.

[0091] Or, such as Figure 4 As shown, the stator 100 is an arc stator 100b, the conveying channel 11 extends along the arc direction, the second guide path 1012 is formed on the side surface of the cover plate 112 away from the substrate 111, the first roller 230 is suspended in the second guide path 1012, the second roller 250 abuts against the side surface of the armature winding 120 near the cover plate 112, or the second roller 250 abuts against the side surface of the substrate 111 near the cover plate 112.

[0092] This embodiment describes the formation method of the second guide path 1012 and the support method of the second roller 250 when the stator 100 is an arc stator 100b. Specifically, the second guide path 1012 is formed on the side surface of the cover plate 112 away from the substrate 111. Further, the armature winding 120 can be located at the bottom 1013 of the receiving cavity 101, or at the top 1014 of the cavity, or at the side wall 1015. Therefore, when the armature winding 120 is not located at the bottom 1013 of the receiving cavity 101, the second roller 250 can abut against the side surface of the substrate 111 near the cover plate 112; when the armature winding 120 is located at the bottom 1013 of the receiving cavity 101, the second roller 250 can abut against the side surface of the armature winding 120 near the cover plate 112.

[0093] Or, such as Figure 5 As shown, the stator 100 is a commutating stator 100c, and there are multiple transport channels 11. The multiple transport channels 11 extend from the same end in different directions. The second guide path 1012 is formed on the side surface of the cover plate 112 away from the substrate 111. The second guide path 1012 includes multiple sub-guide paths. Each sub-guide path is provided on both sides of a corresponding transport channel 11 along its width direction. The first roller 230 is suspended in a corresponding sub-guide path. The second roller 250 abuts against the side surface of the armature winding 120 near the cover plate 112, or the second roller 250 abuts against the side surface of the substrate 111 near the cover plate 112.

[0094] This embodiment proposes a method for forming the second guide path 1012 and a method for supporting the second roller 250 when the stator 100 is a commutating stator 100c. Specifically, the second guide path 1012 is formed on the side surface of the cover plate 112 facing away from the substrate 111. Since there are multiple conveying channels 11, the second guide path 1012 is divided into multiple sub-guide paths, each sub-guide path being located on both sides of a corresponding conveying channel 11 along its width direction. This helps to further improve the stability and reliability of the mover 200 operation.

[0095] Furthermore, the armature winding 120 can be located at the bottom 1013 of the receiving cavity 101, at the top 1014 of the cavity, or at the side wall 1015. Therefore, when the armature winding 120 is not located at the bottom 1013 of the receiving cavity 101, the second roller 250 can abut against the side surface of the substrate 111 near the cover plate 112; when the armature winding 120 is located at the bottom 1013 of the receiving cavity 101, the second roller 250 can abut against the side surface of the armature winding 120 near the cover plate 112.

[0096] In one specific embodiment, such as Figure 5 As shown, the stator 100 is a commutating stator 100c. The conveying channel 11 includes a first conveying channel 102 and a second conveying channel 103 extending from the same end. The first conveying channel 102 extends in a straight line or an arc direction, and the second conveying channel 103 extends in an arc direction. The second guide path 1012 is formed on the side surface of the cover plate 112 away from the substrate 111. The second guide path 1012 includes a first sub-guide path 10121 and a second sub-guide path 10122. The first sub-guide path 10121 is located on both sides of the first conveying channel 102 along its width direction, and the second sub-guide path 10122 is located on both sides of the second conveying channel 103 along its width direction. The first roller 230 is suspended in the first sub-guide path 10121 or the second sub-guide path 10122. The second roller 250 abuts against the side surface of the armature winding 120 near the cover plate 112, or the second roller 250 abuts against the side surface of the substrate 111 near the cover plate 112.

[0097] In this embodiment, the stator 100 is a commutating stator 100c, and has a first conveying channel 102 and a second conveying channel 103 with different extending directions, the second conveying channel 103 being an arc channel. Correspondingly, the second guide path 1012 includes a first sub-guide path 10121 and a second sub-guide path 10122. This configuration ensures that the depths of the first sub-guide path 10121 and the second sub-guide path 10122 are the same, thereby improving the conveying stability of the mover 200 during the turning process. Furthermore, when the mover 200 runs on the commutating stator 100c, regardless of which conveying channel 11 it follows, there is a corresponding limit on the sub-guide path, further enhancing the conveying stability of the mover 200 during the turning process.

[0098] It is readily understood that in some other embodiments, the second conveying channel 103 can also be a straight channel. In this case, when both the first conveying channel 102 and the second conveying channel 103 extend in a straight direction, the first conveying channel 102 and the second conveying channel 103 generally form a "Y"-shaped diversion or confluence structure. When the first conveying channel 102 extends in a straight direction and the second conveying channel 103 extends in an arc direction, the first conveying channel 102 and the second conveying channel 103 generally form an "r"-shaped or reverse "r"-shaped diversion or confluence structure. By flexibly setting the extension direction of the first conveying channel 102 and the second conveying channel 103, the motor conveying device 10 can meet various types of diversion or confluence, thereby improving the convenience and versatility of the motor conveying device 10 in construction.

[0099] In some embodiments, such as Figure 5 and Figure 6 As shown, the stator 100 also includes a switching component 130 connected to the stator base 110. The switching component 130 is configured to guide the mover 200 to move along the first conveying channel 102 or along the second conveying channel 103.

[0100] In this embodiment, since the first conveying channel 102 and the second conveying channel 103 are connected, they share a common slot opening. Furthermore, one slot wall of the first conveying channel 102 and one slot wall of the second conveying channel 103 are connected. Specifically, as shown... Figure 5 and Figure 6 As shown, the first conveying channel 102 and the second conveying channel 103 converge at the first slot opening 104. The first conveying channel 102 has a first slot wall 1021 and a second slot wall 1022, and the second conveying channel 103 has a third slot wall 1031 and a fourth slot wall 1032. The second slot wall 1022 and the third slot wall 1031 are connected.

[0101] This embodiment sets up a switching component 130 to guide the movement of the mover 200, so that the mover 200 can only move along the first conveying channel 102 or only along the second conveying channel 103. This helps to further improve the reliability and stability of the movement of the mover 200 on the stator base 110, as well as improve the reliability of the motor conveying device 10 in realizing the functions of diversion and convergence.

[0102] In some embodiments, such as Figure 5 and Figure 6 As shown, the switching component 130 includes a drive member 131 and a blocking member 132. The drive member 131 is connected to the cover plate 112, and the blocking member 132 is connected to the output end of the drive member 131. The drive member 131 is used to drive the blocking member 132 to move between a first position and a second position. Figure 6 As shown, when the blocking member 132 is in the first position, it blocks the first slot opening 104 and the second conveying channel 103, and the blocking member 132 abuts against the moving body 210 to guide the moving body 210 to run along the first conveying channel 102; as Figure 5 As shown, when the blocking member 132 is in the second position, it blocks the first slot opening 104 and the first conveying channel 102, and the blocking member 132 abuts against the moving body 210 to guide the moving body 210 to run along the second conveying channel 103.

[0103] This embodiment describes a specific method by which the switching component 130 guides the mover 200 to move along the first conveying channel 102 or the second conveying channel 103. The switching component 130 includes a driving member 131 and a blocking member 132, which can move between a first position and a second position under the drive of the driving member 131. When the blocking member 132 is in the first position ( Figure 6 When the first slot opening 104 and the second conveying channel 103 are in the second position, the blocking member 132 can block the first slot opening 104 and the second conveying channel 103, so that the mover 200 can only move along the first slot opening 104 to the first conveying channel 102, or along the first conveying channel 102 to the first slot opening 104. When the blocking member 132 is in the second position ( Figure 5 When the first groove opening 104 and the first conveying channel 102 are separated, the mover 200 can only move along the first groove opening 104 to the second conveying channel 103, or along the second conveying channel 103 to the first groove opening 104. This helps to further improve the reliability and stability of the mover 200 in realizing the diversion or merging function.

[0104] Furthermore, such as Figure 5 and Figure 6As shown, the drive member 131 and the second conveying channel 103 are located on the same side of the first conveying channel 102. Since the drive member 131 needs to drive the blocking member 132 to isolate the first conveying channel 102 or the second conveying channel 103, setting the drive member 131 and the second conveying channel 103 on the same side of the first conveying channel 102 helps to improve the convenience of connecting the drive member 131 and the blocking member 132.

[0105] Furthermore, such as Figure 7 As shown, the drive unit 131 includes an electric push rod 1311, a first connecting rod 1312, and a second connecting rod 1313. The electric push rod 1311 is connected to the stator base 110, the first connecting rod 1312 is connected to the output end of the electric push rod 1311, one end of the second connecting rod 1313 is hinged to the first connecting rod 1312, and the other end of the second connecting rod 1313 is hinged to the blocking member 132, which is also hinged to the stator base 110. Thus, when the electric push rod 1311 extends or retracts, it drives the first connecting rod 1312 and the second connecting rod 1313 to move, which in turn causes the second connecting rod 1313 to rotate the blocking member 132 relative to the stator base 110. This allows the blocking member 132 to move between a first position and a second position, thereby guiding the mover 200 to move on the first conveying channel 102 or the second conveying channel 103 of the stator base 110.

[0106] It is easy to understand that the drive component 131 can also be configured in other ways, such as a combination of a cylinder and a connecting rod; or, the connecting rod structure can be omitted, and the output end of the electric push rod 1311 can be directly connected to the blocking component 132, etc. This application does not limit this.

[0107] Furthermore, the principle by which the blocking member 132 can guide the mover 200 to move along the first conveying channel 102 or the second conveying channel 103 is as follows: Figure 7As shown, the blocking member 132 has a first abutment surface 1321 and a second abutment surface 1322 disposed opposite to each other along the width direction of the first conveying channel 102. The second abutment surface 1322 is located on the side of the first abutment surface 1321 away from the second conveying channel 103. When the blocking member 132 is in the first position, the second abutment surface 1322 of the blocking member 132 can be spliced ​​with the second groove wall 1022 of the first conveying channel 102 to form a new guide sidewall, so that the bearing 2132 of the mover body 210 abuts against the first groove wall 1021 and the new guide sidewall respectively, thereby guiding the mover 200 to move between the first groove opening 104 and the first conveying channel 102. When the blocking member 132 is in the second position, the first abutting surface 1321 of the blocking member 132 can be spliced ​​with the third groove wall 1031 of the second conveying channel 103 to form a new guide sidewall, so that the bearing 2132 of the mover body 210 abuts against the fourth groove wall 1032 and the new guide sidewall respectively, thereby guiding the mover 200 to move between the first groove opening 104 and the second conveying channel 103.

[0108] In a specific embodiment, such as Figures 5 to 7 As shown, the first conveying channel 102 extends in a straight line, and the second conveying channel 103 extends in an arc direction. At least a portion of the first abutment surface 1321 is an arc surface, and the second abutment surface 1322 is a plane. This arrangement allows the first abutment surface 1321 to be joined with the third groove wall 1031 of the second conveying channel 103 to form a new arc-shaped guide sidewall, and the second abutment surface 1322 to be joined with the second groove wall 1022 of the first conveying channel 102 to form a new planar guide sidewall. This, in turn, helps to further improve the reliability and stability of the movement body 210 during operation.

[0109] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
