Description

The control method of electromagnetism joint Manipulator
Present patent application is divisional application.The patent No. of original bill is 201510092211.7, and the applying date is 2015 3 The moon 2, denomination of invention is electromagnetism joint Manipulator and its feeding patient and control method.
Technical field
The present invention relates to a kind of flexible manipulator, more particularly to it is a kind of be used to capturing dixie cup, feeding patient manipulator And its crawl, feeding, control method.
Background technology
Automated machine replace progressively replace people during, automated machine with its strong environmental adaptability, do not know The tired, plurality of advantages such as use cost is low, become the mark of future technology.However, complicated mechanical mechanism easily produce it is all Multiple faults, bulky big machinery can not the general fine and smooth operations of complete imaging human.
During automated machine replaces people, the same flexible shoulder joint of similar true man all is being created all the time, is being come Completion grabs egg, grabs dixie cup or even captures disposable foamed plastic cutlery box and feeds the fine and smooth work such as epidemic victim.Tradition is soft Property arm use parallel between three groups of gear-rack drives, two planks mostly or make it have angle, then carried out tandem group Close, so as to complete the structure of a flexible arm.
However, rack-and-pinion mode drive it is excessively inflexible.When grabbing thing, just grasp can not meet to pick up east true man The requirement in west, the subcutaneous fat of true man can also be directed to and be grabbed thing and hold the fine setting of shape.So during dixie cup is picked up only Fixed grip position can be designed according to the solid shape of dixie cup to pick up dixie cup, required precision is high before and after fixing grip position.Gear The flexible arm of rack mode can not be finely adjusted for dixie cup grip position.During feeding patient, the posture that patient has a meal is not fixed, when Trickle change can often occur, if the manipulator of feeding can not adapt to the minor variations of posture in patient's mouth, it is likely that injure Patient, or even to endanger patient sick.

The grasping means of electromagnetism joint Manipulator of the present invention, comprises the following steps:
A, bending amplitude, dynamics and the crawl posture in each joint of human hands are recorded.
B, multiple electromagnetic flexible joints are together in series and form emulation joint, the upper plate in downside electromagnetic flexible joint and upside The lower plate in electromagnetic flexible joint is fixedly connected, and reference man's palmistry is the same as the amplitude in opening position joint, adjustment electromagnetic flexible joint Number.
C, mechanical palms, mechanical finger, mechanical arm are connected with emulation joint.
Electromagnetism joint Manipulator difference from prior art of the present invention is that electromagnetism joint Manipulator of the present invention passes through electricity Magnetic flexible joint replaces the mechanical joint of gear-rack drive to be captured to object (such as dixie cup) or carried out to epidemic victim Feeding, adjustability when can play electromagnetic flexible joint and arrive tiny error.When manipulator captures dixie cup, electromagnetic flexible closes Festival-gathering imitate the fat on human hand so as to share equally dixie cup it is outside extend out power, successfully capture dixie cup and do not destroy dixie cup. During manipulator feeding epidemic victim, reduce the possibility that medical personnel are infected, and contain spoon in patient and shut up down When swallowing, the action of bowing when electromagnetic flexible joint can also swallow for patient moves downward with patient, greatly reduces mistake The possibility of sick and wounded people.Three telescopic masts in electromagnetic flexible joint uniformly divide according to lower plate circumferential 0 °, 120 °, 240 ° of circumferences Cloth, then it can change upper plate and the angle of lower plate when telescopic mast stretches, so that electromagnetic flexible joint any angle is bent.Its Middle telescopic mast is flexible using electromagnet and permanent magnet control, then is transported using magnet above and below the repulsive force driving push rod of homopolarity It is dynamic, realize the flexible of expansion link.And the flexible sleeve of round table-like inner chamber it is maximum can to limit it when permanent magnet rises as guide rail Displacement.
In electromagnetism joint Manipulator of the present invention if push rod be rigid posts if using spring eliminate push rod at the top of with upper plate it Between bending force.
Flexible push rod then can voluntarily eliminate the bending force between upper plate at the top of push rod in electromagnetism joint Manipulator of the present invention. But flexible link easily mutually friction, or produce skew in flexible sleeve, then set spacing ring to carry out permanent magnet spacing, it is suitable Just flexible push rod is play the guiding role.
If desired expansion link has enough extending forces in electromagnetism joint Manipulator of the present invention, then certainly will strengthen electromagnet Magnetic.But three expansion links hypotelorism after all, interfere and easily cause driving chaotic, then it is same on the barrel of flexible sleeve Between centers can reduce interfering for three expansion links every embedded ring shielding magnetism, and Mumetal materials can make only The magnetic screen thin slice ring of 0.0508 millimeters thick, then its frivolous performance do not influence the degree of crook of expansion link, and be electromagnetic flexible Joint loss of weight.Interval between ring shielding magnetism is more than ring shielding magnetism height 1/5, then does not reach good Magnetic Shielding Effectiveness.Use When, one of them of the first battery, the second battery are because of the magnetic induction line wire cutting line not shielded between ring shielding magnetism Circle, so as to being powered to it, another electromagnet electric discharge to telescopic mast, interleaved power, electric discharge can work while charge, Protect the life of storage battery.
It is steering spirit that limit set in electromagnetism joint Manipulator midpoint of the present invention, which contacts with each other as contact of the point with face, its advantage, It is living.
Face limit set contacts with each other as an elongated cambered surface in electromagnetism joint Manipulator of the present invention.Its advantage is holding posture It is relatively stable.
The degree of crook that mankind's hand is simulated in the grasping means of electromagnetism joint Manipulator of the present invention adjusts the electricity of different numbers Magnetic flexible joint is contacted, and human hand can be copied to manufacture manipulator to greatest extent, make its purposes more extensive.
The electromagnetism joint Manipulator to the present invention and its feeding and control method are described further below in conjunction with the accompanying drawings.
