Description

Technical Field

[0001] This utility model relates to the field of magnetic transport, specifically to a moving part transfer device and a magnetic transport system. Background Technology

[0002] A magnetic conveying system is a system that uses electromagnetic principles to drive the movement of materials or products on a conveyor line. It typically consists of stator coils arranged in a straight line or circular arc, a moving magnetic plate, a position feedback stationary plate arranged in a straight line or circular arc, a passive position feedback moving plate, linear or circular arc guide rails, and a corresponding control system. Due to its high speed, high precision, and flexible scheduling, magnetic conveying systems are increasingly used in factory automation, product transportation, and other applications.

[0003] To achieve flexible scheduling, magnetic conveyor systems are generally equipped with a mover transfer device, i.e., a connection module. The conveyor line can be composed of segmented conveyor line modules. By setting up the connection module, the mover, acting as the conveying vehicle, can be switched from one conveyor line module to another. To meet the requirements of high speed and high precision, the docking accuracy between the connection module and the conveyor line module in the magnetic conveyor system needs to be improved; specifically, the docking accuracy between the guide rails on the connection module and the guide rails on the conveyor line module needs to be improved. Utility Model Content

[0004] To address the above problems, this utility model provides a moving-electrode transfer device and a magnetic conveying system, which can solve the problem of low docking accuracy between the connection module and the conveyor line module.

[0005] The first aspect of this utility model provides a moving element transfer device for use in a magnetic conveying system. The moving element transfer device includes a drive unit, a fixed bracket, and an adjustable bracket. The bottom of the fixed bracket is connected to the drive unit, and the fixed bracket has side walls extending along the height direction. The top surface of the adjustable bracket is used to receive the guide rail extension that connects with the conveyor rail of the magnetic conveying system. The side of the adjustable bracket is fixed to the side wall of the fixed bracket using slotted screws in a height-adjustable manner.

[0006] In this way, the height of the adjustable bracket relative to the side wall of the fixed bracket can be adjusted, which helps to improve the height adjustment accuracy during the transfer of the moving part and enhance the reliability of the transfer. Furthermore, because slotted screws are installed on the side, the height can be locked after adjustment. The locking action is only in the lateral direction and will not affect the height adjustment result or accuracy, facilitating accurate docking of the moving part transfer device and the magnetic conveying system in the height direction.

[0007] Optionally, the slotted screw includes a slotted hole extending along the height direction, the slotted hole being located on the side wall of the fixed bracket, or on the side of the adjustable bracket. In this way, the slotted screw can engage with the slotted hole to achieve height adjustment of the adjustable bracket.

[0008] Optionally, an adapter plate is provided at the bottom of the fixed bracket, through which the fixed bracket connects to the drive unit. This method prevents the fixed bracket from being directly connected to the drive unit, thus helping to ensure structural stability.

[0009] A second aspect of this invention provides a magnetic conveying system, including the moving part transfer device described above. Through this method, the magnetic conveying system can improve the docking accuracy in height during moving part transfer.

[0010] Optionally, the magnetic conveying system also includes a mover assembly and multiple conveyor line modules. The conveyor line guide rail is set on the conveyor line module, and the drive unit drives the fixed bracket and the adjustable bracket to move, thereby docking with different conveyor line modules and transferring the mover assembly from one conveyor line module to another.

[0011] In this way, the drive unit drives the fixed bracket and the adjustable bracket to dock with different conveyor line modules in the horizontal direction, which helps to ensure the docking accuracy in the horizontal direction when the mover is transferred.

[0012] Optionally, the mover assembly includes a mover bracket, a mover magnetic plate, and a mover position feedback plate. The mover bracket is connected to the conveyor rail of the conveyor module and the rail extension on the adjustable bracket. The mover magnetic plate is disposed on the mover bracket. The mover position feedback plate is disposed on the mover bracket.

[0013] In this way, the mover assembly can be connected to the adjustable bracket, which helps to realize the transfer of the mover assembly between the conveyor module and the adjustable bracket.

[0014] Optionally, the adjustable bracket is provided with a stator coil near the mover magnetic plate, and the stator coil is coupled to the mover magnetic plate. The adjustable bracket is provided with a mover position feedback fixed plate near the mover position feedback plate, and the mover position feedback fixed plate is coupled to the mover position feedback plate.

[0015] By setting the stator coil and the mover position feedback plate on the adjustable bracket in the above way, the mover magnetic plate and the mover position feedback plate can be transferred between the conveyor module and the adjustable bracket.

[0016] Optionally, the mover assembly also includes a slider, which is disposed on the side of the mover bracket near the guide rail extension and is slidably connected to the conveyor rail. By configuring the slider in this way, the mover assembly can move on the conveyor rail.

[0017] Optionally, a conveyor rail is disposed on the top surface of the conveyor module, and the moving part slides between the conveyor module and the adjustable bracket via the conveyor rail and its extension. In this manner, the moving part can be moved from the conveyor module to the adjustable bracket, or from the adjustable bracket to another conveyor module, thus enabling the transfer of the moving part.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To facilitate understanding of the technical solution of this utility model, the technical problems of this utility model will be described in detail below.

[0025] The alignment accuracy between the guide rails on the connector module and the guide rails on the conveyor module can be categorized by direction into height accuracy, horizontal accuracy, and angular accuracy. From engineering practice, guide rail alignment is less sensitive to angular accuracy but highly sensitive to height and horizontal accuracy. Horizontal accuracy can be guaranteed by the positioning accuracy of the connector module's drive unit. Height alignment accuracy is more difficult to guarantee.

[0026] The main reason for the low height accuracy is that there is a long dimensional chain between the guide rail on the connecting module and the guide rail on the conveyor line, making it difficult to achieve the required docking accuracy by controlling the accuracy of each part on the dimensional chain. Furthermore, it is difficult to guarantee the height accuracy of the height adjustment bolts during assembly; when tightening after height adjustment, the tightening action will affect the already adjusted height accuracy.

[0027] To address the aforementioned problems, this invention provides a moving element transfer device applied to a magnetic conveying system, which ensures docking accuracy during moving element transfer. It should be noted that the moving element transfer device in this invention is applied to the connection module.

[0028] <Motor Transfer Device 100>

[0029] Figure 1 This is a schematic diagram of the moving part transfer device 100 in an embodiment of this utility model. (Reference) Figure 1 The moving-electrode transfer device 100 includes a drive unit 110, a fixed bracket 120, and an adjustable bracket 130. The bottom of the fixed bracket 120 is connected to the drive unit 110. The side wall of the fixed bracket 120 has a certain height, and the height of the side wall of the fixed bracket 120 matches the height of the conveyor line module 220 of the magnetic conveying system 200. The drive unit 110 can drive the fixed bracket 120 to move horizontally, so that the fixed bracket 120 and the conveyor line module 220 can be horizontally connected. The adjustable bracket 130 is located on the side wall of the fixed bracket 120. The top surface of the adjustable bracket 130 has a guide rail extension 131, which can be connected to the conveyor line guide rail 221 on the conveyor line module 220. The slotted screw 140 passes through the side wall of the fixed bracket 120 and fixes the adjustable bracket 130 to the fixed bracket 120 in a height-adjustable manner (specifically, the fixed position of the adjustable bracket 130 in the height direction is adjustable).

[0030] In this way, the height of the adjustable bracket 130 relative to the side wall of the fixed bracket 120 can be adjusted, which helps to improve the height adjustment accuracy during the transfer of the moving part and enhance the reliability of the transfer. Furthermore, because slotted screws 140 are provided on the side of the adjustable bracket 130 or the side wall of the fixed bracket 120, the height can be locked using the slotted screws 140 after the height adjustment is completed. The locking action is only in the lateral direction and will not affect the height adjustment result and accuracy, facilitating accurate docking of the moving part transfer device 100 and the magnetic conveying system 200 in the height direction.

[0031] Figure 2 This is a schematic diagram of the slotted screw 140 in an embodiment of this utility model. (Combined with...) Figure 1 And refer to Figure 2The slotted screw 140 includes a slotted hole 141 that extends along the height direction of the side wall of the fixed bracket 120. The range of the slotted hole 141 is the adjustment range of the adjustable bracket 130 in the height direction. The slotted hole 141 can be configured in two ways: first, it is located on the side wall of the fixed bracket 120; second, it is located on the side of the adjustable bracket 130. Through these methods, the slotted screw 140 can cooperate with the slotted hole 141 to achieve adjustment of the adjustable bracket 130 in the height direction of the fixed bracket 120.

[0032] Continue to refer to Figure 1 A transition plate 121 is provided at the bottom of the fixed bracket 120, and the fixed bracket 120 is connected to the drive unit 110 through the transition plate 121. Specifically, the transition plate 121 can be installed on the slide of the drive unit 110. By setting the transition plate 121 between the fixed bracket 120 and the drive unit 110 in this way, the fixed bracket 120 is prevented from being directly connected to the drive unit 110, which helps to ensure the stability and safety of the moving part transfer device 100 structure. Furthermore, separating the connection between the fixed bracket 120 and the drive unit 110 and the connection between the fixed bracket 120 and the adjustable bracket 130 helps to reduce the maintenance cost of the fixed bracket 120.

[0033] <Magnetic Transport System 200>

[0034] This utility model also provides a magnetic conveying system 200, including the moving part transfer device 100 as described above. Through the above methods, the magnetic conveying system 200 can improve the docking accuracy in height during moving part transfer.

[0035] Continue to refer to Figure 1 The magnetic conveying system 200 includes a mover assembly 210 and multiple conveyor line modules 220. The mover assembly 210 carries a mover that serves as a conveying carrier, and the conveyor line modules 220 are components of the conveyor line. Conveyor line guide rails 221 are mounted on the conveyor line modules 220. The drive unit 110 drives a fixed bracket 120 and an adjustable bracket 130 to move horizontally, thereby docking with different conveyor line modules 220 and transferring the mover assembly 210 from one conveyor line module 220 to another via the fixed bracket 120 and the adjustable bracket 130.

[0036] In the above manner, the drive unit 110 drives the fixed bracket 120 and the adjustable bracket 130 to dock with different conveyor line modules 220 in the horizontal direction, which helps to ensure the docking accuracy in the horizontal direction when the moving part is transferred, and further improves the working efficiency of the magnetic conveying system 200.

[0037] Specifically, the magnetic conveying system 200 may further include a frame 230, on which the drive unit 110 and the conveyor module 220 are all mounted. The frame 230 on which the drive unit 110 is mounted and the frame 230 on which the conveyor module 220 is mounted can be the same frame 230, or they can be different frames 230 with fixed relative positions, thereby ensuring that the distance between the drive unit 110 and different conveyor modules 220 meets the equidistant requirement.

[0038] <Motor Component 210>

[0039] Continue to refer to Figure 1 The mover assembly 210 includes a mover bracket 211, a mover magnetic plate 212, a mover position feedback plate 213, and a slider 214. The mover bracket 211 is U-shaped and can be divided into an upper end, a middle part, and a lower end. The recessed part of the middle part of the mover bracket 211 engages horizontally with the top part of the adjustable bracket 130. The mover magnetic plate 212 is disposed on the top surface of the lower end of the mover bracket 211. The mover position feedback plate 213 is disposed on the bottom surface of the lower end of the mover bracket 211.

[0040] In the above manner, when the moving part 210 moves from the conveyor rail 221 to the rail extension 131 on the adjustable bracket 130, the moving part 210 can move from the conveyor module 220 to the adjustable bracket 130, thereby realizing the transfer of the moving part 210 between different conveyor modules 220 and the moving part transfer device 100.

[0041] Continue to refer to Figure 1 The adjustable bracket 130 is U-shaped. The adjustable bracket 130 can be divided into an upper end, a middle part, and a lower end. One side of the middle part of the adjustable bracket 130 abuts against the fixed bracket 120, and the other side is engaged with the lower end of the mover bracket 211. The stator coil 132 is disposed on the bottom surface of the upper end of the adjustable bracket 130, and the stator coil 132 is coupled to the mover magnetic plate 212. The mover position feedback plate 133 is disposed on the top surface of the lower end of the adjustable bracket 130, and the mover position feedback plate 133 is coupled to the mover position feedback moving plate 213.

[0042] By setting the stator coil 132 and the mover position feedback plate 133 on the adjustable bracket 130, the mover magnetic plate 212 and the mover position feedback plate 213 can be moved relative to the adjustable bracket 130 along with the mover bracket 211, thereby transferring between different conveyor line modules 220 through the adjustable bracket 130.

[0043] Continue to refer to Figure 1By setting slider 214, the movable support 211 and the adjustable support 130 are connected via a guide rail-slider 214. Specifically, slider 214 is disposed on the bottom surface of the upper end of the movable support 211 and near the guide rail extension 131 on the top surface of the upper end of the adjustable support 130. Slider 214 can slide on the conveyor rail 221. In this way, by setting slider 214 on the movable support 211, the movable assembly 210 can move on the conveyor rail 221 and the guide rail extension 131.

[0044] <Conveyor Line Module 220>

[0045] Continue to refer to Figure 1 The conveyor rail 221 is disposed on the top surface of the conveyor module 220. The mover assembly 210 slides between the conveyor module 220 and the adjustable bracket 130 via the conveyor rail 221 and the rail extension 131. In this way, the mover assembly 210 can move from the conveyor module 220 to the adjustable bracket 130, or from the adjustable bracket 130 to another conveyor module 220, realizing the transfer of the mover assembly 210.

[0046] The working process of this utility model will be explained below in conjunction with its working principle.

[0047] Install the adapter plate 121 onto the drive unit 110, and install the fixed bracket 120 onto the top surface of the adapter plate 121, but do not tighten it yet. Install the stator coil 132 and the mover position feedback plate 133 onto the adjustable bracket 130, and tighten them. Install the adjustable bracket 130 onto the fixed bracket 120, and connect them using the slotted screws 140, but do not tighten them yet.

[0048] Drive the drive unit 110 to align the adjustable bracket 130 with the first conveyor module 220 in the horizontal direction. The conveyor rail 221 is extended from the top surface of the first conveyor module 220 to the top surface of the adjustable bracket 130. The conveyor rail 221 extending to the top surface of the adjustable bracket 130 serves as a reference for determining whether the height adjustment is in place.

[0049] After completing the alignment in the height direction, adjust the gap between the adjustable bracket 130 and the first conveyor module 220, and press the fixed bracket 120 tightly against the adjustable bracket 130. Lock the fixed bracket 120 onto the adapter plate 121, and finally lock the adjustable bracket 130 and the fixed bracket 120 together with the slotted screws 140.

[0050] Next, the bridging conveyor rail 221 is removed and reinstalled into the first conveyor module 220. A rail extension 131 is installed on the top surface of the adjustable bracket 130. The rail extension 131 can be accurately connected to the conveyor rail 221, and the mover assembly 210 is connected to the mover transfer device 100.

[0051] Continue driving the drive unit 110 to align the mover transfer device 100 with the second conveyor module 220 in the horizontal direction. This transfers the mover assembly 210 on the guide rail extension 131 to the conveyor rail 221 of the second conveyor module 220, thus realizing the transfer of the mover assembly 210.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
