With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0032] In the battery production process, the magnetic levitation feeding platform can be used to feed battery pole pieces and other materials. The Magnetic Levitation Feeding Platform is a conveying system based on magnetic levitation technology, which has the advantages of high precision, high speed, and low energy consumption. The Magnetic Levitation Feeding Platform is driven by electromagnetic force to suspend the goods on the track to achieve frictionless operation, thereby greatly reducing energy loss and improving transportation efficiency.

[0033] However, in the related art, the magnetic levitation feeding platform is usually arranged horizontally, and can only realize the horizontal transportation of objects.

[0034] Based on this, the embodiment of the present application discloses a magnetic levitation feeding platform including: a feeding support, a magnetic levitation support plate, a carrying assembly and a control assembly. The feeding support is vertically arranged; the magnetic levitation support plate is vertically arranged on the feeding support, and a closed-loop transport path is arranged on the magnetic levitation support plate along its circumferential direction; the carrying assembly can be movably arranged on the closed-loop transport path, and moves along the closed-loop transport path through the magnetic driving force generated between the magnetic levitation support plate; the control assembly is connected to the magnetic levitation support plate and the carrying assembly signal to control the carrying assembly to move along the closed-loop transport path. Among them, the control assembly is also used to control the acceleration of the carrying assembly in the vertical direction to decrease in response to the power failure of the carrying assembly. The maglev feeding platform is set up vertically, and a closed-loop transport path is set on the maglev support plate along its circumferential direction to form a closed ring transmission path. The carrying component moves along the closed-loop transport path through the magnetic driving force generated between the maglev support plate and the carrying component, thereby realizing direct driving of the carrying component in the vertical direction, thereby realizing the transportation of materials in the vertical direction, improving the feeding efficiency of the maglev feeding platform while also improving the safety of the maglev feeding platform.

[0035] The magnetic levitation feeding platform disclosed in the embodiment of the present application can be applied to industries such as electrical machinery and equipment manufacturing, pharmaceutical industry, consumer electronics, biomedicine and automotive electronics.

[0036] The embodiment of the present application provides a magnetic levitation feeding platform, Figure 1 The structure of the magnetic levitation feeding platform of some embodiments of the present application is shown in FIG. Figure 1 , Figure 2 This is a partially enlarged structural schematic diagram of a magnetic levitation feeding platform in some embodiments of the present application. Figure 3 This is a schematic diagram of the structure of the magnetic levitation support plate of some embodiments of the present application. Figure 4 Schematic diagram of the structure of the carrier assembly of some embodiments of the present application Figure 1 , Figure 5 Schematic diagram of the structure of the carrier assembly of some embodiments of the present application Figure 2 , Figure 6 The structure of the magnetic levitation feeding platform of some embodiments of the present application is shown in FIG. Figure 2 ,like Figures 1 to 6As shown, the magnetic levitation feeding platform 1000 includes: a feeding support 110, a magnetic levitation support plate 120, a carrier assembly 130 and a control assembly 140. The feeding support 110 is vertically arranged; the magnetic levitation support plate 120 is vertically arranged on the feeding support 110, and a closed-loop transport path is arranged on the magnetic levitation support plate 120 along its circumferential direction; the carrier assembly 130 can be movably arranged on the closed-loop transport path, and moves along the closed-loop transport path through the magnetic driving force generated between the magnetic levitation support plate 120; the control assembly 140 is connected to the magnetic levitation support plate 120 and the carrier assembly 130 by signal, and controls the carrier assembly 130 to move along the closed-loop transport path. Among them, the control assembly 140 is also used to control the acceleration of the carrier assembly 130 in the vertical direction to decrease in response to the power failure of the carrier assembly 130.

[0037] In the embodiment of the present application, the feeding support 110 is vertically arranged to provide a supporting force for the magnetic levitation support plate 120 so that the magnetic levitation support plate 120 can also be vertically arranged.

[0038] The magnetic levitation support plate 120 may include a magnetic drive stator, and the carrier assembly 130 may include a magnetic driver. The magnetic driver is the rotating part of the motor, usually composed of an iron core and a winding. When current passes through the winding, a magnetic field is generated, and this magnetic field interacts with the magnetic field of the magnetic drive stator, thereby generating a rotational torque, causing the magnetic driver to start rotating. The magnetic drive stator is the stationary part of the motor, also composed of an iron core and a winding. The magnetic field of the magnetic drive stator is usually provided by an external power supply, interacts with the magnetic field of the magnetic driver, and guides the rotation of the magnetic driver. The interaction between the magnetic driver and the magnetic drive stator realizes the conversion of electrical energy into mechanical energy. The magnetic field of the magnetic drive stator interacts with the magnetic field of the magnetic driver, converting electrical energy into mechanical energy, driving the magnetic driver to rotate. Therefore, the carrier assembly 130 can move along the closed-loop transport path set along the circumferential direction of the magnetic levitation support plate 120 through the magnetic drive force generated between the carrier assembly 130 and the magnetic levitation support plate 120.

[0039] The carrier assembly 130 can be movably arranged on a closed-loop transport path arranged along the circumference direction of the magnetic suspension support plate 120. There can be multiple carrier assemblies 130. The multiple carrier assemblies 130 can move along the closed-loop transport path in sequence through the magnetic driving force generated between the carrier assemblies 130 and the magnetic suspension support plate 120. The carrier assembly 130 can be used to load objects. In other words, the carrier assembly 130 can move in the vertical direction to carry objects.

[0040] The control component 140 can receive signals from the magnetic levitation support plate 120 and the carrier component 130 to control the carrier component 130 and control the carrier component 130 to move along the closed-loop transport path. The control component 140 can include a programmable logic controller (PLC), a human machine interface (HMI), an iTS controller and a stator main switchboard (MSB), wherein the PLC is a commonly used controller in industrial automation, responsible for logic control and data processing, the HMI provides an interactive interface between the operator and the machine, allowing the operator to monitor and control the production process, the iTS controller is a controller specifically used in industrial automation, responsible for coordinating and controlling various equipment and processes, and the stator MSB board is part of the motor control, used to drive and adjust the operation of the motor. These components work together to ensure the normal operation and efficient operation of the control component 140.

[0041] The carrier assembly 130 moves in the vertical direction. After the carrier assembly 130 is powered off, the carrier assembly 130 loses the magnetic driving force generated between it and the magnetic levitation support plate 120. At this time, the carrier assembly 130 will move downward rapidly with a vertical downward acceleration under the action of gravity. If no external force is applied at this time, the carrier assembly 130 will quickly fall to the bottom and be damaged.

[0042] In order to avoid damage to the carrier assembly 130, the control assembly 140 can control the acceleration of the carrier assembly 130 in the vertical direction to decrease. Specifically, the stator MSB board in the control assembly 140 detects that the carrier assembly 130 is not in the set position, and the stator MSB board feeds back a signal to the iTS controller. The iTS controller can control the coil inside the magnetic levitation support plate 120 to close, and the magnetic levitation support plate 120 can generate a magnetic force opposite to the movement direction of the carrier assembly 130. The gravity of the carrier assembly 130 will be partially offset, so that the acceleration speed of the carrier assembly 130 in the vertical direction will decrease, which increases the time for the carrier assembly 130 to move in the vertical direction, reduces the probability of damage to the carrier assembly 130, and improves the safety of the magnetic levitation feeding platform 1000.

[0043] In the embodiment of the present application, the magnetic levitation feeding platform 1000 is arranged vertically, and a closed-loop transport path is arranged on the magnetic levitation support plate 120 along its circumferential direction to form a closed ring transmission path. The carrying component 130 moves along the closed-loop transport path through the magnetic driving force generated between the magnetic levitation support plate 120 to achieve direct driving of the carrying component 130 in the vertical direction, thereby realizing the transportation of materials in the vertical direction, improving the feeding efficiency of the magnetic levitation feeding platform 1000 while also improving the safety of the magnetic levitation feeding platform 1000.

[0044] According to some embodiments of the present application, the magnetic levitation feeding platform 1000 further includes a brake assembly 150, and the control assembly 140 is further used to control the brake assembly 150 to stop the carrying assembly 130 from running.

[0045] Exemplarily, the brake assembly 150 may include a brake cylinder 151, a brake block provided on the carrier assembly 130, and a brake block provided on the magnetic suspension support plate 120. When the stator MSB board in the control assembly 140 detects that the carrier assembly 130 is not in the set position, a feedback signal is sent to the PLC, and the PLC may control the brake cylinder 151 to extend, and the brake block provided on the carrier assembly 130 and the brake block provided on the magnetic suspension support plate 120 are pressed against each other to generate friction, and the friction decelerates the carrier assembly 130 until it stops. The carrier assembly 130 can be stopped in time after the carrier assembly 130 is powered off.

[0046] In the embodiment of the present application, by providing a brake assembly 150, the control assembly 140 controls the brake assembly 150 to stop the operation of the carrier assembly 130, so that the carrier assembly 130 can be stopped in time after the power is cut off from the carrier assembly 130, thereby further reducing the probability of damage to the carrier assembly 130.

[0047] According to some embodiments of the present application, the brake assembly 150 includes a brake cylinder 151 , and the magnetic levitation feeding platform 1000 also includes a one-way valve gas tank 160 , which is used to supply air to the brake cylinder 151 .

[0048] The brake cylinder 151 converts compressed air into mechanical energy, thereby achieving a braking function on the carrier assembly 130, so that the carrier assembly 130 stops moving.

[0049] The one-way valve gas tank 160 controls the opening and closing of the valve by utilizing the gas pressure and the gravity of the valve disc. When the gas enters the valve from the gas tank, the valve disc of the one-way valve will automatically open, and the gas can enter the engine combustion chamber through the one-way valve unimpeded. On the contrary, when the gas flows back, the one-way valve will close quickly, effectively preventing the gas from flowing back and ensuring the normal operation of the machine. The one-way valve gas tank 160 supplies gas to the brake cylinder 151 to ensure the normal operation of the brake cylinder 151.

[0050] In the embodiment of the present application, a one-way valve air tank 160 and a brake air cylinder 151 are provided to ensure the normal operation of the brake assembly 150 .

[0051] According to some embodiments of the present application, the magnetic levitation feeding platform 1000 further includes a positioning component 170 , which is located on the magnetic levitation support plate 120 , and the positioning component 170 is used to position the carrying component 130 on the magnetic levitation support plate 120 .

[0052] A positioning assembly 170 is provided on the magnetic levitation support plate 120, and the positioning assembly 170 is used to position the position of the carrier assembly 130 on the magnetic levitation support plate 120, so as to facilitate the control assembly 140 to control the start and stop of the carrier assembly 130. There can be multiple positioning assemblies 170, and one positioning assembly 170 can be provided for each lifting target position. The positioning assembly 170 can be a sensor.

[0053] In the embodiment of the present application, the positioning assembly 170 is located on the magnetic levitation support plate 120 and is used to position the carrier assembly 130 on the magnetic levitation support plate 120 , which can be used to ensure the stability and position accuracy of the carrier assembly 130 on the magnetic levitation support plate 120 .

[0054] According to some embodiments of the present application, the positioning component 170 includes a plurality of positioning sensors.

[0055] ‌ Positioning sensors provide feedback primarily by detecting the position of an object, which can be achieved by measuring distance or angular motion. Positioning sensors can detect the linear or angular motion of an object, determining its position by measuring the distance between an object and a fixed point or the angle through which the object rotates. Specifically, positioning sensors can determine the displacement of an object by measuring the distance between two points, or calculate the distance it has traveled by detecting the angular motion of an object (such as the rotation of a robot's wheels).

[0056] Positioning sensors can include many types, including potentiometric position sensors, inductive position sensors, eddy current sensors, capacitive position sensors, magnetostrictive position sensors, magnetic position sensors based on the Hall effect, fiber optic position sensors, optical position sensors, and ultrasonic position sensors, among others.

[0057] Exemplarily, in the embodiments of the present application, the positioning sensor may include a loading completion sensor, a loading level in place sensor, a unloading completion sensor, and a unloading level in place sensor.

[0058] In the embodiment of the present application, the positioning accuracy of the positioning component 170 can be improved by using multiple positioning sensors, thereby improving the overall reliability and stability of the magnetic levitation feeding platform 1000.

[0059] According to some embodiments of the present application, the magnetic levitation support plate 120 includes a limiting guide rail 121 , and the limiting guide rail 121 is used to provide guidance for the carrying assembly 130 .

[0060] The limiting guide rail 121 can be arranged on the magnetic levitation support plate 120 along its circumferential direction, and can overlap with the closed-loop transport path arranged on the magnetic levitation support plate 120 along its circumferential direction. The limiting assembly is used to guide the transport assembly 130 along the closed-loop transport path, so as to improve the reliability and stability of the movement of the transport assembly 130.

[0061] In the embodiment of the present application, the limiting guide rail 121 provided on the magnetic levitation support plate 120 provides guidance for the carrier assembly 130, thereby improving the reliability and stability of the movement of the carrier assembly 130.

[0062] According to some embodiments of the present application, the carrying assembly 130 includes a carrying support 131, a magnetic levitation seat 132 and a material picking and placing component 133, one side of the magnetic levitation seat 132 is fixedly connected to the carrying support 131, and a U-shaped opening is provided on the other side of the magnetic levitation seat 132, and the U-shaped opening is embedded in the limiting guide rail 121, and the material picking and placing component 133 is provided on the carrying support 131 for carrying objects.

[0063] The magnetic levitation seat 132 is arranged on the side wall of the carrier support 131 and is close to the magnetic levitation support plate 120 so as to generate magnetic force with the magnetic levitation support plate 120. After receiving the magnetic force, the magnetic levitation seat 132 drives the carrier assembly 130 to move and is guided and limited by the U-shaped opening. The material taking and placing component 133 is arranged on the carrier support 131, and a carrying plane is formed on the material taking and placing component 133 for carrying objects.

[0064] In the embodiment of the present application, a U-shaped opening is provided on the magnetic levitation seat 132, and the U-shaped opening is embedded in the limiting guide rail 121, thereby improving the reliability and stability of the movement of the carrying component 130, and the material picking and releasing component 133 is provided on the carrying support 131, so that the carrying component 130 can continuously supply items along the circular conveying path, thereby greatly improving the production efficiency.

[0065] According to some embodiments of the present application, the transport assembly 130 further includes a guide wheel 134 , which is rotatably disposed on one side of the magnetic levitation seat 132 and slides freely along the closed-loop transport path.

[0066] The number of the guide wheels 134 may be one or more, and the guide wheels 134 guide the carrier assembly 130 .

[0067] In the embodiment of the present application, the guide wheel 134 cooperates with the guide rail to achieve the limitation and guidance of the movement of the carrier assembly 130, and in the vertical direction, the guide wheel 134 and the guide rail can be out of contact, so that the carrier assembly 130 can be lifted vertically.

[0068] According to some embodiments of the present application, the magnetic levitation feeding platform 1000 further includes a temporary power supply 180 , which is used to supply power to the magnetic levitation feeding platform 1000 .

[0069] The temporary power supply 180 is a power protection device that uses a battery as a power source. When the city power fails, the energy stored in the battery can be converted into alternating current to continue to power the maglev feeding platform 1000, ensuring that the maglev feeding platform 1000 continues to operate during the power failure, preventing data loss or damage to the maglev feeding platform 1000. The temporary power supply 180 also has voltage stabilization and filtering functions, which can ensure the stability and purity of the power supply and prevent the maglev feeding platform 1000 from being damaged due to voltage instability and other reasons.

[0070] In the embodiment of the present application, the temporary power supply 180 is used to power the magnetic levitation feeding platform 1000 to ensure that the magnetic levitation feeding platform 1000 continues to operate during the power outage, thereby preventing data loss or damage to the magnetic levitation feeding platform 1000.

[0071] According to some embodiments of the present application, the magnetic levitation feeding platform 1000 further includes a feed conveying mechanism 190 , which is used to convey the object to be transported to the initial transport position of the transport component 130 .

[0072] In the embodiment of the present application, the feed conveying mechanism 190 can rise to the initial material conveying position of the carrier assembly 130 to convey the object to be transported to the initial material conveying position of the carrier assembly 130. The feed conveying mechanism 190 can be a shaft screw conveyor or a pneumatic conveying system.

[0073] In the embodiment of the present application, the material conveying mechanism is used to convey the object to be transported to the initial material conveying position of the carrying component 130, so that the conveying of the object to be transported can be completed continuously, thereby improving the feeding efficiency of the magnetic levitation feeding platform 1000.

[0074] According to some embodiments of the present application, the magnetic levitation feeding platform 1000 further includes a discharge conveying mechanism 200 , and the discharge conveying mechanism 200 has a feed end, and the transport target position of the transport component 130 is aligned and connected with the feed end.

[0075] In the embodiment of the present application, the subsequent material conveying is performed by the discharge conveying mechanism 200. The discharge conveying mechanism 200 may be a chain conveyor. The discharge conveying mechanism 200 can realize continuous and efficient material conveying, reduce the time and labor intensity of manual handling, and improve the overall efficiency of the production line. Through automated conveying equipment, materials can be quickly and accurately transferred between different processes to ensure the smooth progress of the production process.

[0076] In the embodiment of the present application, efficient, flexible and stable transportation of materials is achieved through the discharge conveying mechanism 200.

[0077] The second aspect of the present application provides a control method for a magnetic levitation feeding platform, which is applied to the magnetic levitation feeding platform of any one of the above embodiments. Figure 7 This is a flow chart of the control method of some embodiments of the present application, such as Figure 7 As shown, the control method includes: step S710, controlling the carrier assembly to move along the closed-loop transport path set along the circumferential direction of the magnetic suspension support plate in the vertical direction. Step S720, in response to the carrier assembly being powered off, controlling the carrier assembly to reduce its acceleration in the vertical direction.

[0078] In the embodiment of the present application, the feeding support is vertically arranged to provide supporting force for the magnetic levitation support plate so that the magnetic levitation support plate can also be vertically arranged.

[0079] The magnetic levitation support plate may include a magnetic drive stator, and the carrier assembly may include a magnetic driver. The magnetic driver is the rotating part of the motor, usually composed of an iron core and a winding. When current passes through the winding, a magnetic field is generated, and this magnetic field interacts with the magnetic field of the magnetic drive stator, thereby generating a rotational torque, causing the magnetic driver to start rotating. The magnetic drive stator is the stationary part of the motor, also composed of an iron core and a winding. The magnetic field of the magnetic drive stator is usually provided by an external power supply, interacts with the magnetic field of the magnetic driver, and guides the rotation of the magnetic driver. The interaction between the magnetic driver and the magnetic drive stator realizes the conversion of electrical energy into mechanical energy. The magnetic field of the magnetic drive stator interacts with the magnetic field of the magnetic driver, converting electrical energy into mechanical energy and driving the magnetic driver to rotate. Therefore, the carrier assembly can move along the closed-loop transport path set along the circumferential direction of the magnetic levitation support plate through the magnetic drive force generated between the carrier assembly and the magnetic levitation support plate.

[0080] The transport assembly can be movably arranged on a closed-loop transport path arranged along the circumference of the magnetic levitation support plate. The number of the transport assemblies can be multiple, and the multiple transport assemblies can move along the closed-loop transport path in sequence through the magnetic driving force generated between the magnetic levitation support plate and the transport assembly can be used to load objects. In other words, the transport assembly can run in the vertical direction to transport objects.

[0081] The control component can receive signals from the magnetic levitation support plate and the carrier component to control the carrier component and control the carrier component to move along the closed-loop transport path. The control component can include a programmable logic controller (PLC), a human machine interface (HMI), an iTS controller and a stator main switchboard (MSB). Among them, the PLC is a commonly used controller in industrial automation, responsible for logic control and data processing, the HMI provides an interactive interface between the operator and the machine, allowing the operator to monitor and control the production process, the iTS controller is a controller specifically used in industrial automation, responsible for coordinating and controlling various equipment and processes, and the stator MSB board is part of the motor control, used to drive and adjust the operation of the motor. These components work together to ensure the normal operation and efficient operation of the control component.

[0082] The carrier assembly moves in the vertical direction. After the power is cut off, the carrier assembly loses the magnetic driving force generated between the carrier assembly and the magnetic levitation support plate. At this time, the carrier assembly will move downward rapidly at a vertical downward acceleration due to the action of gravity. If no external force is applied at this time, the carrier assembly will quickly fall to the bottom and be damaged.

[0083] In order to avoid damage to the carrying component, the control component can control the acceleration of the carrying component in the vertical direction to decrease. Specifically, the stator MSB board in the control component detects that the carrying component is not in the set position, and the stator MSB board feeds back a signal to the iTS controller. The iTS controller can control the closure of the coil inside the magnetic levitation support plate, and the magnetic levitation support plate can generate a magnetic force opposite to the movement direction of the carrying component. The gravity of the carrying component will be partially offset, so that the acceleration speed of the carrying component in the vertical direction will be reduced, which increases the time for the carrying component to move in the vertical direction, reduces the probability of damage to the carrying component, and improves the safety of the magnetic levitation feeding platform.

[0084] In the embodiment of the present application, the magnetic levitation feeding platform is arranged vertically, and a closed-loop transport path is arranged on the magnetic levitation support plate along its circumferential direction to form a closed ring transmission path. The carrying component moves along the closed-loop transport path through the magnetic driving force generated between the magnetic levitation support plate, thereby realizing direct driving of the carrying component in the vertical direction, thereby realizing the transportation of materials in the vertical direction, improving the feeding efficiency of the magnetic levitation feeding platform while also improving the safety of the magnetic levitation feeding platform.

[0085] According to some embodiments of the present application, the magnetic levitation feeding platform also includes a brake assembly, and the control method also includes: step S730, controlling the brake assembly to stop the carrying assembly.

[0086] Exemplarily, the brake assembly may include a brake cylinder, a brake block provided on the carrier assembly, and a brake block provided on the magnetic suspension support plate. When the stator MSB board in the control assembly detects that the carrier assembly is not in the set position, a signal is fed back to the PLC, and the PLC may control the brake cylinder to extend, and the brake block provided on the carrier assembly and the brake block provided on the magnetic suspension support plate are pressed against each other to generate friction, and the friction decelerates the carrier assembly until it stops. The carrier assembly can be stopped in time after the carrier assembly is powered off.

[0087] In the embodiment of the present application, a brake assembly is provided and the control assembly controls the brake assembly to stop the operation of the carrier assembly. The carrier assembly can be stopped in time after the power of the carrier assembly is cut off, thereby further reducing the probability of damage to the carrier assembly.
