Description
Technical Field
The invention belongs to the field of magnetically controlled soft robots, and in particular relates to a magnetically soft pump device with a bidirectional pumping function and an operation control method thereof.
Background
The soft robot is a main body or main functional structure made of soft material (elastic modulus is 10) 4 Pa-10 9 A material between Pa). Compared with the traditional rigid robot, the soft robot has the advantages of high degree of freedom, strong deformability, good adaptability and the like, and has wide application prospect in the fields of bioengineering, medical treatment and the like. Soft pump robots have received attention for their wide application in the medical rehabilitation field of artificial hearts and artificial soft fingers. Compared with a rigid pump, the soft pump body has the remarkable advantages of light weight, flexibility, no noise pollution and the like, and becomes one of the integrated power source choices for the development of fluid robots.
In the prior art, the soft pump body has various driving modes, including peristaltic film driving (commonly known as a micro-fluid peristaltic film pump realized by thermal driving and electrostatic force driving), electric response dielectric elastomer driving, magnetic driving and the like. However, peristaltic membrane driven pump body flow rates typically range from nanoliters per minute to microliters, which are insufficient for large actuators and soft robots. Although electrically responsive dielectric elastomer actuator pumps have a significant increase in liquid flow rate, the pumped working liquid is limited to dielectric fluids and the operating voltage is high (> 10 kV). However, magnetically driven soft pump bodies have considerable pump body flow rates and no limitations of pumping liquid media. Meanwhile, compared with other driving modes, the electromagnetic driving mode has the remarkable advantages of non-contact, strong controllability, good penetrability and the like.
However, the existing magnetic control soft pump has the problem that the bidirectional pumping of the fluid is difficult to directly realize. Because the driving power of the soft body is relatively small compared with that of the rigid body, the existing magnetic soft body pump needs a one-way or controllable fluid valve to cooperate in order to ensure pumping efficiency. The commercial check valve is simpler in structure and widely applied because of no need of control wiring, but has the problems of unique conduction direction and limited flow. Other controllable fluid valves often require additional control connections, increasing the complexity and difficulty of control of the device. Therefore, the conventional magnetically controlled soft pump has the problem that the bidirectional pumping of the fluid is difficult to directly realize.

Embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
Aiming at the defects or improvement demands of the prior art, the invention provides a magnetic soft pump body with a bidirectional pumping function and a method thereof by utilizing a double-shaft driving magnetic field regulation technology, and aims to realize the bidirectional pumping of the same magnetic soft pump body to fluid by decoupling control of a soft pump body and a magnetic control valve through the matching of the magnetic soft pump body and the double-shaft driving magnetic field, thereby solving the unidirectional pumping problem in the prior magnetic soft pump technology.
FIG. 1 is a schematic diagram of an embodiment of a magnetic soft pump body with bi-directional pumping according to the present invention; as shown in fig. 1, the magnetic pump body includes: the magnetic soft valve comprises a left magnetic soft valve body 1-1, a left magnetic soft valve suction lock 1-2, a magnetic control pump body 2, a fixed container 3, a right magnetic soft valve body 4-1 and a right magnetic soft valve suction lock 4-2.
Wherein, the magnetic soft valve bodies 1-1 and 4-1: after being mixed with the magnetic powder NdFeB and silica gel, the mixture was prepared by a mold into a shape as shown in fig. 1, and then solidified. Magnetizing the magnetic soft valve body through a pulse magnetic field device to obtain the magnetic soft valve body in the vertical upward magnetization direction (Z-axis positive direction) in figure 1.
Magnetic soft valve suction locks 1-2 and 4-2: the preparation process is the same as the process of the valve body of the magnetic soft valve, the valve body is prepared into the shape shown in figure 1 through different moulds, the magnetic soft valve suction lock is magnetized through a pulse magnetic field device,

Magnetic control pump body 2: the preparation process is the same as that of the magnetic soft valve, the magnetic soft valve is prepared into a disc shape as shown in fig. 1 through different dies, and the magnetic control pump body is subjected to magnetizing treatment through a pulse magnetic field device, so that the magnetic control pump body with radial outward magnetizing directions (radial divergence of XY plane) as shown in fig. 1 is obtained.
Fixing container 3: the magnetic soft valve is prepared by 3D printing and is mainly used for fixing and connecting a magnetic soft valve body, a suction lock and a pump body, and a closed flow passage is provided for pumping fluid.
Furthermore, in order to ensure the tightness, a fixed groove of a magnetic soft valve and a magnetic control pump body with specific sizes is reserved on the fixed container, and the good tightness of the magnetic soft pump is realized by pasting the sealing glue.
Further, in order to realize the magnetic control action of the magnetic soft valve, the magnetization directions of the magnetic soft valve body and the suction lock are determined. The valve body of the left magnetic control valve can be positively magnetized along the Z axis, and the suction lock can be negatively magnetized along the X axis, so that the lower end of the suction lock has a magnetic adsorption effect on the valve body, and self-locking closure under the condition of no magnetic field is realized.

s1, connecting two ends of a magnetic soft pump body prepared according to the structure to two water containers through fixing members respectively, and ensuring the tightness of connection;
s2, a magnetic soft pump is placed in a triaxial Helmholtz coil, and an X coil and a Z coil of the Helmholtz coil are connected to an alternating current power amplifier;

Further, the pumping efficiency of the magnetic soft pump can be controlled by regulating and controlling the strength of the double-shaft magnetic field; the pumping direction of the magnetic soft pump can be controlled by regulating and controlling the phase of the double-shaft magnetic field.
