Description

Technical Field

[0001] This invention relates to the field of magnetic levitation technology, specifically to a magnetic levitation ring conveyor and a conveying method. Background Technology

[0002] The magnetic levitation system consists of four parts: a rotor, a sensor, a controller, and an actuator. The actuator includes an electromagnet and a power amplifier. Assuming the rotor is at a reference position and is subjected to a downward disturbance, it will deviate from its reference position. The sensor detects the displacement of the rotor from the reference point. The microprocessor, acting as the controller, converts the detected displacement into a control signal. Then, the power amplifier converts this control signal into a control current. The control current generates a magnetic force in the actuator magnet, thereby driving the rotor back to its original equilibrium position. Therefore, regardless of whether the rotor is subjected to a downward or upward disturbance, the rotor can always maintain a stable equilibrium state.

[0003] In the existing technical field, magnetic levitation circular conveying uses a similar invention, CN109051821A, to provide a more stable magnetic levitation circular conveying device to adapt to different transport rails. This magnetic levitation circular conveying device includes: a circular guide rail; V-shaped protrusions on both sides of the circular guide rail; a load assembly mounted on the circular guide rail; the load assembly includes a drive mechanism for driving the load assembly to move along the circular guide rail and four V-shaped rollers; two of the V-shaped rollers are located on one side of the circular guide rail and engage with the V-shaped protrusions, and the other two V-shaped rollers are located on the other side of the circular guide rail and engage with the V-shaped protrusions; each V-shaped roller has a rotation axis; at least one V-shaped roller has a concentric rotation axis, and at least one V-shaped roller has an eccentric rotation axis. However, this device is not convenient for precise braking of the load assembly when carrying heavy objects, resulting in a large braking distance required for the load assembly.

The mounting bracket is connected to a ring-shaped guide rail, which is circumferentially positioned on top of the mounting frame. A movable blocking module is positioned on the outer side of the ring-shaped guide rail. The outer side of the mounting frame is circumferentially spaced with several braking components, each including a fixed base, a mounting base, a blocking base, and a first electric actuator. The fixed base is mounted on the inner wall of the mounting frame. The mounting base is positioned on the outer wall of the mounting frame. The blocking base is rotatably connected to the inner side of the mounting base via a pin. One end of the first electric actuator is rotatably connected to the bottom end of the fixed base via a pin, and the other end of the first electric actuator is rotatably connected to the bottom end of the blocking base via a pin. The first electric actuator is electrically connected to the controller.

[0009] Preferably, to achieve rapid external braking during high-speed circular material conveying, the moving blocking module includes: a base, limiting wheels, electromagnets, permanent magnet plates, a slot, a storage shell, a rotating shell, a second electric push rod, a rotating frame, a rotating rod, a third electric push rod, a connecting rod, and a hook; the base is positioned above the circular guide rail in a left-right direction; four limiting wheels are rotatably connected to the four corners of the base bottom via pins, with the inner sides of the four limiting wheels contacting the outer side of the circular guide rail; four electromagnets are spaced apart and installed from left to right on the front side of the limiting wheels, and the electromagnets are electrically connected to the controller; four permanent magnet plates are spaced apart and installed on the front side of the inner transmission belt of the transmission belt assembly; the slot is positioned on the rear side of the base; the storage shell is positioned in a left-right direction...

[0010] Preferably, the rotating frame is L-shaped.

[0011] The specific conveying method for the above-mentioned equipment is as follows:

[0012] Step 1: The moving module carries the material tray and moves circumferentially along the inner side of the annular magnetic levitation stator track;

[0013] Step 2: The linear motion module drives the vision recognition module to move horizontally on both sides above the annular magnetic levitation stator rail. When the vision recognition module captures the material conveying mechanism moving to the designated processing position, it sends a signal to the controller.

[0014] Step 3: The pulley inside the first motor drive transmission belt assembly drives the belt to move circumferentially in the opposite direction to the workpiece's movement trajectory, thereby driving the moving barrier module to move in the corresponding position with the cooperation of the permanent magnet plate and electromagnet.

[0015] Step 4: The second electric actuator extends to drive the rotating outer shell to rotate upward with the pivot point of the rotating connection with the storage outer shell as the apex, thereby causing the rotating outer shell to rotate out of the inner cavity of the storage outer shell;

[0016] Step 5: The third electric actuator extends and pushes the rotating rod to move with the help of the connecting rod. With the help of the rotating frame, the rotating rod flips upward with the pin joint between the rotating frame and the rotating housing as the apex, and the rotating rod drives the hook to flip upward so that the hook engages with the inside of the hook piece, thereby achieving the initial braking of the material conveying mechanism at the corresponding position.

[0017] Step Six: The electromagnet stops being magnetically attracted to the permanent magnet plate, thereby releasing the connection between the moving barrier module and the transmission belt assembly;

[0018] Step 7: The first electric actuator extends to drive the blocking seat to rotate upward with the pivot point of the mounting seat as the apex, and inserts the blocking seat into the slot of the corresponding position of the moving blocking module to achieve locking, thereby realizing precise position braking of the material conveying mechanism through the moving blocking module.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The material tray carried by the moving module moves along the inner side of the annular magnetic levitation stator track. The linear motion module drives the vision recognition module to move horizontally on both sides above the annular magnetic levitation stator track. When the vision recognition module captures the material conveying mechanism moving to the designated processing position, it sends a signal to the controller.

[0021] 2. The first motor drives the transmission belt assembly to drive the moving blocking module to move circumferentially in the opposite direction to the workpiece's movement trajectory. The second electric push rod drives the rotating housing to rotate upward out of the inner cavity of the receiving housing. The third electric push rod, in cooperation with the connecting rod, pushes the rotating rod to drive the hook to flip upward. The hook engages with the inner side of the hook component to achieve initial braking of the material conveying mechanism at the corresponding position. The electromagnet stops being attracted to the permanent magnet plate, thereby releasing the connection between the moving blocking module and the transmission belt assembly. The first electric push rod drives the blocking seat to insert into the slot seat in the moving blocking module at the corresponding position to achieve engagement, thereby stopping the moving blocking module at the designated position and achieving precise position braking of the material conveying mechanism through the moving blocking module.

[0022] This enables rapid braking during the magnetic levitation high-speed circular conveyor process, shortens the braking distance, and allows for precise braking during the conveying of heavier materials, making the material movement position more accurate. Attached Figure Description
