DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0023] It should be noted that all the direction indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the direction indications will also change accordingly.

[0024] In addition, the descriptions such as "first", "second" and the like in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can be explicitly or implicitly included at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0025] In the present application, unless otherwise specifically defined and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "fixation" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] In addition, the technical solutions of each embodiment of the present application can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the scope of protection claimed in the present application.

[0027] In the related art, the conveying line includes a stator and a mover, the stator can be arranged along a horizontal plane, at this time the mover can move on the horizontal plane, thereby driving the workpiece to move on the horizontal plane. Or the stator can also be arranged along a vertical plane, at this time the mover can move on the vertical plane, thereby driving the workpiece to move on the vertical plane. When the stator loses power during the rising process of the mover, the mover in the rising stage will lose power, thereby falling reversely downward, and further possibly colliding with other movers to cause damage to the line body.

[0028] As Figures 1-2 shown, the first aspect of the embodiments of the present application provides a magnetic drive conveying system 100, which comprises a magnetic drive conveying line body 110, a limiting piece 120 and a cooperating piece 130.

[0029] The magnetic drive conveying line body 110 comprises a stator module 111 and a mover module 112 magnetically coupled with the stator module 111, and the stator module 111 can drive the mover module 112 to move along the stator module 111.

[0030] Exemplarily, the stator module 111 is provided with an armature winding, the armature winding includes a plurality of coils arranged in a phase sequence, and the magnetic field around the armature winding can be changed by periodically energizing the armature winding. The mover module 112 can be provided with a permanent magnet array, the permanent magnet array generates a constant magnetic field around the mover module 112, when the energizing direction and / or the energizing current of the coils in the armature winding are changed, a variable magnetic field around the armature winding can be generated, the variable magnetic field interacts with the constant magnetic field, and the interaction can drive the mover module 112 to move relative to the stator module 111, so that the mover module 112 can move without energization, thereby reducing the wiring difficulty. It should be noted that the mover module 112 is not limited to cooperating with the stator module 111 by using the permanent magnet array, and the mover module 112 can also use coils and the like, so that the mover module 112 can move relative to the stator module 111 by cooperating with the variable magnetic field around the stator module 111, and no limitation is made in this regard.

[0031] The mover module 112 and the stator module 111 can be in contact or not in contact when sliding, the stator module 111 can assist in bearing the mover module 112 when the mover module 112 and the stator module 111 are in contact. When the mover module 112 and the stator module 111 are not in contact, the sliding resistance can be reduced, and the mover module 112 can be borne by other components.

[0032] The stator module 111 includes an ascending section 1111, the movement direction of the mover module 112 on the ascending section 1111 has a component in a first direction A, the first direction A is a vertically upward direction, that is, the mover module 112 moves on the ascending section 1111 in a non-horizontal direction, that is, the mover module 112 moves on the ascending section 1111 in a direction obliquely upward or vertically upward, the movement of the mover module 112 on the ascending section 1111 can be decomposed into movement in the vertically upward direction and movement in the horizontal direction, or the movement of the mover module 112 on the ascending section 1111 is movement in the vertically upward direction. The component can be understood as the movement amount of the mover module 112 in the vertically upward direction, and the mover module 112 has a component in the first direction A, that is, the movement amount of the mover module 112 in the vertically upward direction is greater than zero.

[0033] That is, the height of the mover module 112 gradually increases when the mover module 112 moves along the ascending section 1111. The conveying path of the ascending section 1111 can be a straight line, a curve, or a combination of a straight line and a curve.

[0034] Optionally, the ascending section 1111 can be composed of an arc-shaped stator or can be spliced by a plurality of straight-line stators.

[0035] The limiting piece 120 is arranged on the ascending section 1111, and the cooperating piece 130 is arranged on the mover module 112. The connecting mode of the limiting piece 120 and the ascending section 1111 may, for example, be welding, bonding, screwing, or integral molding. The connecting mode of the cooperating piece 130 and the mover module 112 may, for example, be welding, bonding, or screwing, which is not limited herein.

[0036] The limiting piece 120 can cooperate with the cooperating piece 130 to fix the cooperating piece 130 relative to the limiting piece 120, so as to prevent the mover module 112 from sliding off the ascending section 1111. When the stator module 111 is suddenly powered off, the cooperating piece 130 stops moving relative to the limiting piece 120, so that the mover module 112 stops moving. By setting the cooperation direction of the limiting piece 120 and the cooperating piece 130, the mover module 112 can only ascend and cannot slide off, so as to avoid collision between the plurality of mover modules 112, improve the safety of the magnetic drive conveying system 100, and reduce the probability of damage of the magnetic drive conveying system 100.

[0037] In some embodiments, the cooperating piece 130 can only move relative to the limiting piece 120 in a single direction. Since the cooperating piece 130 cannot move reversely relative to the limiting piece 120, by setting the cooperation direction of the cooperating piece 130 and the limiting piece 120, the mover module 112 can only ascend and cannot slide off.

[0038] Optionally, the limiting piece 120 includes one of a ratchet piece 131 and a pawl piece 121, and the cooperating piece 130 includes the other one of the ratchet piece 131 and the pawl piece 121, that is, the cooperating piece 130 and the limiting piece 120 form a ratchet mechanism. The structure of the ratchet mechanism is relatively simple, and the manufacturing and installation are relatively convenient. Since the design principle is relatively intuitive, the complexity and cost can be reduced in the production process. The ratchet mechanism is reliable in movement during work, and can provide stable one-way transmission effect. Due to the design characteristics, the ratchet will not appear reverse sliding or reverse during rotation, and is suitable for occasions requiring stable transmission.

[0039] In some embodiments, the limiting piece 120 includes an electrically operated clamp jaw, and the cooperating piece 130 includes a friction plate. The friction plate extends into the inside of the electrically operated clamp jaw. The electrically operated clamp jaw is configured to be opened when electrified and clamped when de-energized. For example, the electrically operated clamp jaw can include a clamp jaw, an electromagnet, and a spring. The spring exerts a force on the clamp jaw. The clamp jaw is clamped under the action of the spring. The electromagnet can overcome the spring force when electrified to drive the clamp jaw to open. When the electromagnet is de-energized, the clamp jaw is clamped again under the action of the spring.

[0040] The electrically powered clamping jaw is open when electrified, and the friction plate can move freely relative to the electrically powered clamping jaw, that is, the mover module 112 can move relative to the stator module 111 when electrified. It can be understood that the power supply of the electrically powered clamping jaw is generally consistent with that of the stator module 111, and when the stator module 111 loses power, the electrically powered clamping jaw also loses power and clamps, and the friction plate is fixed relative to the electrically powered clamping jaw, that is, the mover module 112 is fixed relative to the stator module 111 when losing power, thereby avoiding reverse falling of the mover module 112.

[0041] As shown in Figure 2 In some embodiments, the pawl piece 121 includes a first base 1211, a pawl 1212, and an elastic piece 1213. The first base 1211 is arranged on the ascending section 1111, and is used to mount the pawl 1212 and the elastic piece 1213, so that the pawl piece 121 is convenient to assemble with the ascending section 1111. The first base 1211 is exemplarily a plate-shaped structure, so as to be relatively thin.

[0042] The pawl 1212 is rotationally connected with the first base 1211, and the elastic piece 1213 is connected with the pawl 1212 and the first base 1211 at both ends, respectively. The elastic piece 1213 applies a force to the pawl 1212 in the second direction B. By arranging the elastic piece 1213, the pawl 1212 can be automatically reset, so that the pawl 1212 has a limiting effect. The elastic piece 1213 is exemplarily a spring, a spring sheet, or the like.

[0043] When the mover module 112 moves along the ascending section 1111, the ratchet piece 131 drives the pawl 1212 to rotate in the third direction C, and the ratchet piece 131 can cooperate with the pawl 1212 to prevent the mover module 112 from sliding off the ascending section 1111. The third direction C is opposite to the rotation direction of the second direction B.

[0044] Optionally, the first base 1211 is provided with a mounting groove, and the pawl 1212 is arranged in the mounting groove. The groove wall of the mounting groove can limit the rotation range of the pawl 1212, so that the pawl 1212 is more stable when rotating. Moreover, arranging the pawl 1212 in the mounting groove can also reduce the occupation of space, thereby reducing the volume of the pawl piece 121.

[0045] As shown in Figure 2 In some embodiments, the number of pawls 1212 is multiple. The more the number of pawls 1212 is, the more dense the pawls 1212 are, and the faster the limiting response speed of the pawls 1212 to the ratchet piece 131 is.

[0046] Optionally, the pawl 1212 covers the conveying path of the ascending section 1111, so that the stator module has the effect of preventing sliding off throughout the ascending section 1111.

[0047] Optionally, the at least two pawls 1212 are simultaneously matched with the ratchet member 131, so that the limiting effect of the pawls 1212 on the ratchet member 131 is better and more reliable.

[0048] As shown in the drawings, Figure 3 In some embodiments, the number of the magnetic drive conveying lines 110, the limiting members 120 and the matching members 130 is two, the two magnetic drive conveying lines 110 are arranged in mirror symmetry along a vertical plane, the two limiting members 120 are arranged on the two rising sections 1111 respectively, and the two matching members 130 are arranged on the two mover modules 112 respectively.

[0049] By arranging two groups of ratchet mechanisms, the probability that the ratchet member 131 and the pawl member 121 fail is lower, and the mover module 112 is less likely to fall back.

[0050] As shown in the drawings, Figure 3 In some embodiments, the magnetic drive conveying system 100 further includes a second base 140, and the two magnetic drive conveying lines 110 are arranged on two sides of the second base 140 respectively.

[0051] That is, the two magnetic drive conveying systems 100 share one second base 140, so that the structure of the magnetic drive conveying system 100 is relatively compact, which is conducive to the miniaturization of the magnetic drive conveying system 100. In addition, the two magnetic drive conveying systems 100 share one second base 140, which can save costs. In addition, since the two magnetic drive conveying systems 100 are both installed on the second base 140, that is, the two magnetic drive conveying systems 100 are both based on the second base 140, which is conducive to improving the installation precision of the two magnetic drive conveying systems 100, so that the two magnetic drive conveying systems 100 can be easily assembled in mirror symmetry, and the installation difficulty is reduced.

[0052] Optionally, the second base 140 is a structure arranged in mirror symmetry along a vertical plane, so that the overall structure of the magnetic drive conveying system 100 is in mirror symmetry, which is conducive to the balance of the force on both sides of the magnetic drive conveying system 100, and the space occupation on both sides is the same.

[0053] As shown in the drawings, Figure 3 In some embodiments, the second base 140 includes a base 141, a first protrusion 142 and a second protrusion 143. The base 141 can be plate-shaped, so as to be more stable.

[0054] The first protrusion 142 is arranged on the base 141, the base 141 has two first surfaces 141a respectively located on two sides of the first protrusion 142, the first protrusion 142 has two second surfaces 142a facing away from each other, and the two second surfaces 142a are connected with the two first surfaces 141a respectively. The second protrusion 143 is arranged on the surface of the second protrusion 143 away from the base 141, the second protrusion 143 has two third surfaces 143a facing away from each other, and the two third surfaces 143a are located between the two second surfaces 142a.

[0055] Each stator module 111 includes a stator body 1114 and a guide 1115, two stator bodies 1114 are fixed on the two first surfaces 141a respectively, and the two stator bodies 1114 are fixed on the two second surfaces 142a respectively. Since the stator body 1114 is fixed with the two surfaces at the same time, the fixing accuracy of the stator body 1114 is higher, and the connection strength between the stator body 1114 and the second base 140 is higher.

[0056] Two guides 1115 are fixed on the two third surfaces 143a respectively, since the third surface 143a is located between the two second surfaces 142a, that is, the guide 1115 is arranged between the two stator bodies 1114, so as to make full use of the space between the two stator bodies 1114, thereby miniaturizing the magnetic drive conveying system 100.

[0057] In some embodiments, the connection mode of the guide 1115 and the second base 140 can be clamping, screwing, one-piece forming, etc., and the connection mode of the stator body 1114 and the second base 140 can be clamping and screwing. The second base 140 can be installed on a mounting platform or the ground, so as to reliably bear the mover module 112, and make the transportation of the mover module 112 more stable.

[0058] In some embodiments, the mover module 112 is slidingly arranged on the guide 1115, and the mover module 112 and the guide 1115 can be directly slidingly connected or slidingly connected through other components. The guide 1115 is used for limiting the moving direction of the mover module 112, so as to make the moving track of the mover module 112 more accurate. Moreover, the guide 1115 has strong bearing capacity, and by arranging the guide 1115, the overall load capacity of the magnetic drive conveying system 100 can be improved, so that the magnetic drive conveying system 100 can convey heavier transportation workpieces.

[0059] In some embodiments, the magnetic driving conveying system 100 further comprises a moving piece 113, the guide piece 1115 is arranged on the second base 140, the moving piece 113 is arranged on the mover module 112, and the moving piece 113 is movably arranged on the guide piece 1115. The guide piece 1115 is used to limit the moving direction of the moving piece 113, so that the moving track of the moving piece 113 is more accurate. Moreover, the guide piece 1115 can be used to bear the carrier 150. By arranging the guide piece 1115, the carrying capacity of the magnetic driving conveying system 100 as a whole can be improved, so that the magnetic driving conveying system 100 is more suitable for conveying heavy transportation workpieces. In addition, since the magnetic driving conveying system 100 bears the stress through the moving piece 113 and the guide piece 1115, the mover module 112 can be arranged in a spaced manner with the stator module 111, so as to avoid friction between the mover module 112 and the stator module 111, reduce the wear between the mover module 112 and the stator module 111, and prolong the service life of the mover module 112 and the stator module 111. It can be understood that the number of moving pieces 113 mounted on a single carrier 150 can be selected according to actual needs. The more the number of moving pieces 113, the greater the carrying capacity. Of course, the number of moving pieces 113 needs to be considered in combination with the weight of the transportation workpiece and the carrying capacity of the carrier 150.

[0060] Exemplarily, the guide piece 1115 is a track, and the track extends along the conveying direction. The moving piece 113 is a rolling wheel or a sliding piece, and the moving piece 113 is arranged in a rolling or sliding manner on the track. The number of moving pieces 113 can be multiple, so as to reduce the stress of a single moving piece 113 and prolong the service life of each moving piece 113. Moreover, arranging multiple moving pieces 113 can also make the carrier 150 slide more stably.

[0061] It should be noted that the specific types of the track and the moving piece 113 are not limited in the embodiments of the present application. For example, the track can be a V-shaped slide rail, and a V-shaped groove is formed on the moving piece 113. The V-shaped slide rail is inserted into the V-shaped groove and cooperates with the V-shaped groove to limit the position of the mover module 112 and make the mover module 112 have higher movement precision when moving. For another example, the track can be a plane slide rail, and the moving piece 113 is arranged on both sides of the plane slide rail to support the movement of the mover module 112 and reduce friction.

[0062] Of course, the guide piece 1115 can also be a guide rod, a guide groove or other components, and the moving piece 113 can also be a sliding block or other components, which are not limited herein.

[0063] Since the two stator modules 111 have the same structure and the two mover modules 112 have the same structure, the two stator modules 111 can be replaced with each other, so the universality is good and the cost can be saved.

[0064] In some embodiments, the stator body 1114 is vertically arranged, so the stator body 1114 occupies a smaller horizontal area, thereby enabling the magnetic drive conveying system 100 of this application to improve the load-bearing capacity of the mover without increasing or significantly increasing the area of ​​the carrier 150.

[0065] Understandably, the mover module 112 and the stator body 1114 have a good magnetic driving force, and the gap between them is usually small. When the stator body 1114 is horizontally positioned, if the bending range of the rising section 1111 is large, the mover module 112 is prone to rubbing against it. However, when the stator body 1114 is vertically positioned, the bending range of the rising section 1111 can be larger, thus making the arrangement of the stator body 1114 more flexible and beneficial to the miniaturization of the magnetic drive conveying system 100.

[0066] like Figure 4 As shown, in some embodiments, the magnetic drive conveyor system 100 further includes a carrier 150 for carrying workpieces. Two moving sub-modules 112 are connected to the carrier 150. The two moving sub-modules 112 can simultaneously drive the carrier 150 to move, thereby increasing the carrying capacity of the carrier 150. When a workpiece is placed on the carrier 150, the two moving sub-modules 112 can share the weight of the carrier 150 and the workpiece, thus reducing the burden on one moving sub-module 112 and increasing the load capacity of the carrier 150. This allows the movement speed of the moving sub-modules 112 in the magnetic drive conveyor system 100 to be increased while maintaining the same driving force for each moving sub-module 112, ensuring the working efficiency of the magnetic drive conveyor system 100.

[0067] By symmetrically arranging the two stator modules 111, the driving force and levitation force at all points on the support platform are made as uniform as possible.

[0068] It is understandable that although the two stator modules 111 provide driving force and levitation force to the mover module 112 respectively, their coils have different spatial magnetic fields. This application arranges the two stator modules 111 as symmetrically as possible so that the mover modules 112 on both sides of the carrier 150 are coupled with the stator with the same spatial magnetic field, thereby ensuring the force balance of the carrier 150.

[0069] In some embodiments, each mover module 112 has the same driving force, and when the magnetic driving conveying system 100 includes two mover modules 112, the pushing force for pushing the carrier 150 to move is increased, thereby accelerating the speed of the mover modules 112 to transport the workpiece, thereby ensuring the working efficiency of the magnetic driving conveying system 100. The carrier 150 can be arranged above all the mover modules 112 or arranged above part of the mover modules 112. The carrier 150 can be used to connect the plurality of mover modules 112 as a whole, and the carrier 150 can also be used as a carrier to transport the workpiece.
