[0005] In a first aspect, embodiments of this application provide a conveying system, which includes a stator module, a mover module, a limiting member, and a mating member.

[0012] In some exemplary embodiments, the opening of the first limiting groove faces vertically downward, the axis of the limiting wheel is vertically set, the two side walls of the first limiting groove restrict the movement of the limiting wheel in the width direction, the width direction is perpendicular to the conveying direction of the moving module and parallel to the horizontal plane, and the bottom wall of the first limiting groove restricts the movement of the limiting wheel vertically upward.

[0013] In some exemplary embodiments, the limiting member extends along the transport direction of the stator assembly, and the limiting member includes a straight segment connected to the bent section.

[0034] like Figure 1-3 As shown, the first aspect of this application provides a conveying system 100, which includes a stator module 110, a mover module 120, a limiting member 130, and a mating member 140.

[0035] The stator module 110 includes a base 111, a guide rail 112 disposed on the base 111, and a stator assembly 113 disposed on the base 111. The base 111 supports the guide rail 112, the stator assembly 113, the mover module 120, and the workpiece to be transported. The guide rail 112 can be connected to the base 111 by snap-fit, screw-fit, or integral molding, etc., and the stator assembly 113 can be connected to the base 111 by snap-fit, screw-fit, etc. The base 111 can be installed on an installation platform or the ground to reliably support the mover module 120, making the transport of the mover module 120 more stable. Typically, the mover module 120 is positioned above the base 111. The stator assembly 113 includes an arc-shaped stator 1131 and a linear stator 1132 connected to the arc-shaped stator 1131. The arc-shaped stator 1131 and the linear stator 1132 can be freely and flexibly combined so that the mover module 120 can perform linear or curved motion as required, that is, the motion trajectory of the mover module 120 can be flexibly set.

[0036] The moving module 120 is slidably mounted on the guide rail 112. The moving module 120 and the guide rail 112 can be directly slidably connected or slidably connected through other components. The guide rail 112 is used to limit the movement direction of the moving module 120, thereby making the movement trajectory of the moving module 120 more precise. Moreover, the guide rail 112 has a strong load-bearing capacity. By setting the guide rail 112, the overall load-bearing capacity of the conveying system 100 can be improved, enabling the conveying system 100 to transport heavier workpieces.

[0037] The mover module 120 is magnetically coupled to the stator assembly 113. Exemplarily, the stator assembly 113 contains an armature winding comprising multiple coils arranged in phase sequence. By periodically energizing the armature winding, the magnetic field around it can be changed. The mover module 120 may be equipped with a permanent magnet array, which generates a constant magnetic field around the mover module 120. When the energizing direction and / or the magnitude of the energizing current in the coils within the armature winding changes, a changing magnetic field can be generated around the armature winding. This changing magnetic field interacts with the constant magnetic field, driving the mover module 120 to move relative to the stator module 110. Thus, the mover module 120 can move without being energized, reducing wiring complexity. It should be noted that the mover module 120 is not limited to using a permanent magnet array to cooperate with the stator module 110. The mover module 120 can also use coils, etc., so that the mover module 120 can move relative to the stator module 110 through the cooperation of the changing magnetic field around the mover module 120 and the changing magnetic field around the stator module 110. There is no limitation on this.

[0038] The limiting member 130 includes a bent segment 131 corresponding to the arc-shaped stator 1131. Optionally, the bent segment 131 is a continuous structure rather than an intermittent structure. When the mover module 120 bends, the limiting member 130 can continuously limit the mover module 120, thereby achieving a better limiting effect. Moreover, the continuous structure of the limiting member 130 usually has higher structural strength, thus adapting to the heavier mover module 120. In addition, the continuous structure of the limiting member 130 has good integrity, making it easy to manufacture and install. The bent segment 131 is disposed on the base 111 and / or the guide rail 112. The bent segment 131 can be directly connected to the base 111 and / or the guide rail 112, or it can be connected to the base 111 and / or the guide rail 112 through the connector 150. Figure 1 As shown, the bent section 131 is connected to both the base 111 and the guide rail 112 via the connector 150. Alternatively, the bent section 131 can be connected only to the base 111 via the connector 150, or only to the guide rail 112 via the connector 150. Optionally, when the connector 150 connects both the base 111 and the guide rail 112, the connector 150 can also enhance the connection strength between the base 111 and the guide rail 112. A mating part 140 is provided on the moving part module 120, and the bent section 131 is engaged with the mating part 140 to prevent the moving part module 120 from detaching from the guide rail 112. By providing the mating part 140, the moving part module 120 can be prevented from directly engaging with the bent section 131, reducing friction in the moving part module 120 and extending its service life.

[0039] It is understandable that when the moving module 120 moves in a straight line, there is no centrifugal force. Therefore, when the moving module 120 moves on the linear stator 1132, there is basically no need to worry about it overturning or derailing. However, when the moving module 120 turns, it will generate centrifugal force. When the moving module 120 turns at a high speed, the centrifugal force generated is large, which may cause it to overturn or derail.

[0040] In this embodiment, a bending section 131 is provided on the corresponding arc-shaped stator 1131, and a mating part 140 is provided on the mover module 120. Through the limiting cooperation between the mating part 140 and the bending section 131, the mover module 120 is less likely to tip over or derail, making it safer and more stable when turning. In addition, due to the limiting effect of the bending section 131, the mover module 120 can also turn at a higher speed, thereby improving transportation efficiency.

[0041] like Figure 1 As shown, in some embodiments, the guide rail 112 includes a first guide rail 1121 and a second guide rail 1122 spaced apart in the horizontal direction. The moving module 120 is slidably disposed on the first guide rail 1121 and the second guide rail 1122. The first guide rail 1121 and the second guide rail 1122 support the moving module 120, thereby making the moving module 120 have a stronger load-bearing capacity and more stable when sliding.

[0042] For example, the curve includes an inner curve on the inside and an outer curve on the outside. One of the first guide rail 1121 and the second guide rail 1122 can be the inner rail and the other can be the outer rail. The following description takes the first guide rail 1121 as the outer rail and the second guide rail 1122 as the inner rail as an example.

[0043] The bent section 131 can be set on the first guide rail 1121 or on the base 111 corresponding to the first guide rail 1121, that is, the bent section 131 is set on the outer track, thereby limiting the outer side of the mover module 120. Generally speaking, the space around the outer track is larger, thus providing sufficient space to arrange the limiting member 130.

[0044] Alternatively, the bent section 131 can be positioned on the second guide rail 1122, or the corresponding second guide rail 1122 can be positioned on the base 111, meaning the bent section 131 is positioned on the inner track, thereby limiting the inner side of the moving module 120. It is understood that when the moving module 120 is turning, the inner side is usually more prone to tipping over or derailing than the outer side. Therefore, limiting the inner side of the moving module 120 can effectively suppress tipping over or derailing. Furthermore, the inner track is shorter than the outer track; therefore, when the bent section 131 is positioned on the inner track, its length will also be shorter, thus saving production costs.

[0045] Alternatively, the bent section 131 can be set on the first guide rail 1121 or on the base 111 corresponding to the first guide rail 1121, and the bent section 131 can also be set on the second guide rail 1122 or on the base 111 corresponding to the second guide rail 1122. That is, both the outer and inner rails are provided with bent sections 131, thereby limiting the inner and outer sides of the moving module 120 at the same time, so as to improve the limiting effect of the bent section 131 on the moving module 120.

[0046] like Figure 1 As shown, in some embodiments, the mover module 120 includes a permanent magnet array 124. The first guide rail 1121 and the second guide rail 1122 are located on both sides of the width direction KK of the permanent magnet array 124. The width direction KK is perpendicular to the conveying direction SS of the mover module 120 and parallel to the horizontal plane. It should be noted that since the guide rail 112 includes a straight section 132 and a bent section 131, the extension direction of the guide rail 112 will change, that is, the conveying direction SS will change. When the conveying direction SS changes, the width direction KK will also change accordingly. The conveying direction SS and width direction KK indicated in the figure are only one example and are not the only indications of the conveying direction SS and width direction KK.

[0047] The first guide rail 1121 and the second guide rail 1122 are located outside the two sides of the width direction KK of the moving module 120. That is, the distance between the first guide rail 1121 and the second guide rail 1122 is greater than the size of the moving module 120 in the width direction KK. In this way, the distance between the first guide rail 1121 and the second guide rail 1122 can be relatively large. The larger the distance between the first guide rail 1121 and the second guide rail 1122, the less likely the moving module 120 is to overturn or derail. This helps to improve the stability of the moving module 120 when turning and reduces the probability of the moving module 120 overturning or derailing.

[0048] like Figure 1-3As shown, in some embodiments, the limiting member 130 is provided with a first limiting groove 130a, which extends along the conveying direction SS of the stator assembly 113. The mating member 140 includes a limiting wheel, which is rotatably disposed on the mover module 120, and the limiting wheel engages with the groove wall of the first limiting groove 130a. The machining difficulty of grooves is generally low, so machining the first limiting groove 130a on the limiting member 130 is relatively easy, and the structure of the limiting member 130 can be relatively simple. Since the limiting wheel can rotate, when the limiting wheel abuts against the groove wall of the first limiting groove 130a, the limiting wheel can roll relative to the groove wall of the first limiting groove 130a, thereby reducing the friction between the mating member 140 and the limiting member 130, and thus reducing the impact of limiting on the operation of the mover module 120. The number of limiting wheels can be one or more, which can be set according to the size of the mover module 120. For example, there are four limit wheels, two of which are respectively located at the front and rear ends of one side of the moving module 120, and the other two are respectively located at the front and rear ends of the other side of the moving module 120.

[0049] In some embodiments, there is a gap between the limiting wheel and the side wall and bottom wall of the first limiting groove 130a. That is, when the moving module 120 is operating normally, the limiting wheel does not abut against the groove wall of the first limiting groove 130a, thereby reducing the resistance of the moving module 120 during movement and increasing the service life of the limiting wheel and the limiting member 130. When the moving module 120 is displaced due to centrifugal force, the limiting wheel abuts against the groove wall of the first limiting groove 130a. The groove wall of the first limiting groove 130a restricts the limiting wheel from moving in directions other than the conveying direction SS, thereby limiting the limiting wheel to prevent the moving module 120 from tipping over or derailing. Furthermore, since there is a gap between the limiting wheel and the side wall and bottom wall of the first limiting groove 130a, that is, the size of the first limiting groove 130a is larger than the size of the limiting wheel, when the limiting wheel moves from the outside of the first limiting groove 130a to the inside of the first limiting groove 130a, the limiting wheel is less likely to collide with the limiting member 130, which is safer.

[0050] like Figure 1-3As shown, in some embodiments, the opening of the first limiting groove 130a faces vertically downwards, the axis of the limiting wheel is vertically set, the extension direction of the groove wall of the first limiting groove 130a is the same as the conveying direction SS of the moving module 120, the two side walls of the first limiting groove 130a restrict the movement of the limiting wheel along the width direction KK, the bottom wall of the first limiting groove 130a restricts the movement of the limiting wheel vertically upwards, and the guide rail 112 can restrict the movement of the moving module 120 vertically downwards. In summary, the moving module 120 is limited in both the vertical and width directions KK, so that the moving module 120 can only move in the conveying direction SS. In addition, since the limiting member 130 is fastened above the limiting wheel, the limiting member 130 can also play a blocking role, thereby minimizing the entry of dust and other debris into the first limiting groove 130a.

[0051] In some other embodiments, the opening of the first limiting groove 130a may also face other directions, as long as the axis of the limiting wheel extends in the same direction as the opening of the first limiting groove 130a.

[0052] like Figure 1-3 As shown, in some embodiments, the limiting member 130 extends along the conveying direction SS of the stator assembly 113, and the limiting member 130 includes a straight segment 132 connected to the bent segment 131. Before the mover module 120 enters the bent segment 131, the mating member 140 can already engage with the straight segment 132 for limiting, thereby ensuring the limiting effect of the mover module 120 and improving the stability of the conveying. Optionally, the limiting member 130 does not completely cover the first straight segment 1321 and the second straight segment 1322, thereby reducing the size of the limiting member 130 and the material required to manufacture the limiting member 130 while ensuring the limiting effect. In addition, the limiting member 130 is connected to the first straight segment 1321, the bent segment 131 and the second straight segment 1322, thereby improving the overall strength of the conveying system 100.

[0053] like Figure 4 As shown, in some embodiments, the bent segment 131 has a first end 1311 and a second end 1312, and the straight segment 132 includes a first straight segment 1321 and a second straight segment 1322. The first straight segment 1321 is connected to the first end 1311, and the second straight segment 1322 is connected to the second end 1312. A limiting member 130 extends to the end of the first straight segment 1321 near the end of the bent segment 131, and the limiting member 130 extends to the end of the second straight segment 1322 near the end of the bent segment 131. The first straight segment 1321 is tangent to the bent segment 131 at the first end 1311, thereby making the transition between the first straight segment 1321 and the bent segment 131 smooth. The second straight segment 1322 is tangent to the bent segment 131 at the second end 1312, thereby making the transition between the second straight segment 1322 and the bent segment 131 smooth.

[0054] like Figure 5-7 As shown, in some embodiments, the mover module 120 includes a mover body 121, a load-bearing wheel 122, and a guide wheel 123. The mover body 121 is provided with a permanent magnet array. The load-bearing wheel 122 and the guide wheel 123 are rotatably mounted on the mover body 121. The load-bearing wheel 122 mainly serves to bear weight. The axis of the load-bearing wheel 122 is horizontally set. The guide rail 112 has a horizontal bearing surface 112a and a vertical guide surface 112b. The load-bearing wheel 122 is rolled on the bearing surface 112a, which can support the load-bearing wheel 122. Since the conveying system 100 bears the load through the load-bearing rollers 122 and the guide rails 112, the mover module 120 can be spaced apart from the stator assembly 113, thereby avoiding friction between the mover module 120 and the stator assembly 113, reducing wear between the mover module 120 and the stator assembly 113, and extending the service life of the mover module 120 and the stator assembly 113.

[0055] The guide wheel 123 mainly serves as a limit. The axis of the guide wheel 123 is vertically set, and the guide wheel 123 is rolled on the guide surface 112b. The guide surface 112b restricts the guide wheel 123 from moving along the width direction KK.

[0056] like Figure 6-7 As shown, in some embodiments, the guide rail 112 has a second limiting groove 112c. The opening of the second limiting groove 112c is horizontal. The bottom wall of the second limiting groove 112c serves as a guide surface 112b. The side wall of the second limiting groove 112c restricts the guide wheel 123 from moving in the vertical direction. That is, the second limiting groove 112c cooperates with the guide wheel 123 to prevent the moving module 120 from tipping over or derailing to a certain extent.

[0057] like Figure 1 and Figure 8 As shown, in some embodiments, the mating member 140 protrudes from the moving module 120 and is further away from the stator module 110 than the limiting member 130. Along a direction perpendicular to the stator module 110, the projection of the mating member 140 coincides with the projection of the limiting member 130. When the moving module 120 turns at a high speed, it will be subjected to centrifugal force and tip over in the outward bending direction. In this embodiment, the mating member 140 is positioned above the limiting member 130, and the projection of the mating member 140 coincides with the projection of the limiting member 130. This ensures that when the moving module 120 tip over in the outward bending direction, the mating member 140 abuts against the limiting member 130, preventing the moving module 120 from tipping over in the outward bending direction. In other words, the limiting member 130 supports the mating member 140, thereby preventing the moving module 120 from tipping over or derailing. In this embodiment, the mating part 140 can also serve to support the workpiece and protect the moving part module 120.
