Description
Technical field
The utility model relates to a kind of manipulator, particularly relates to a kind of manipulator by controlling automatically.
Background technology
Application semi-automatic or the armstrong's patent hand is very extensive in industrial production at present, the major control mode of existing mechanical hand has: the program that weaves control robot movement part according to operating path in advance, carry out according to the program that weaves during use, realize corresponding motion requirement automatically.Other parts or all adopt manual control mode.Existing mechanical hand manually control adopts button to carry out the motion control of lifting or direction of travel etc. mostly, button control has only single speed or double speed usually, this structure can not satisfy in the Industry Control requirement to accurate location and fast moving, and very inconvenience of operation; Also have the potentiometer of employing to control the mode of robot movement speed in addition, but it is bigger to exist the machine driving error, the life-span is limited, the shortcoming that can't respond real-time.Therefore, the manipulator of existing control mode all can not real time reaction goes out Human-to-Machine's the requirement of moving in real time, can't satisfy the requirement that the operator responds real-time for manipulator and real-time mirror operation is intended to, have a strong impact on operating characteristics, the motion effort of controlling manipulator simultaneously is time-consuming.
Summary of the invention
The purpose of this utility model provides a kind of manipulator of automatic control, can react to operator's operation in real time, action that can real time control machine tool hand, it is more accurate to locate, reaction is relatively sensitive, can satisfy in the Industry Control requirement to accurate location and fast moving.
The utility model to achieve the above object, the technical scheme of being taked is:
A kind of manipulator of automatic control is provided, comprises that having dress hangs the manipulator body of hand, the force feedback control system of control hand and the control manipulator body that is connected with the control hand; Described control hand comprises at least one pull pressure sensor; Described force feedback control system comprises at least one force servo controller, at least one driver and at least one motor; Pull pressure sensor in the described control hand accepts to send to behind the signal of control the force servo controller in the force feedback control system, the force servo controller is according to the size and Orientation of control, start driver, the motion of driver drives motor drives manipulator body is hung speed and the direction controlled according to the force servo controller by hanging piece that dress hangs on hand on the manipulator body thereupon and is moved.
The manipulator remarkable benefit of automatic control of the present utility model.
● as above-mentioned structure of the present utility model, because the utility model comprises the control hand, the operator is by the pull pressure sensor input control order in the control hand.When the operator touches the stress point of pull pressure sensor, pull pressure sensor will be touched the power that produces immediately and convert the corresponding signal of telecommunication to, send the force servo controller in the force feedback control system to, the force servo controller is according to the size and Orientation deactivation driver of this signal, the driver drives motor rotates according to the size and Orientation of this signal, and (passing through transmission device) drive the motion of manipulator body, make its hang in dress hang on hand delivered to the position as requested by hanging piece.So the operator is intended to by the operation that the real-time control feedback control system of control hand reaches the operator, the hand that makes described electric manipulator become operator oneself equally moves.Therefore its motion can real time reaction go out the control requirement of operator to electric manipulator, satisfy in the Industry Control needs to accurate location and fast moving, and solved operation inconvenience, control is wasted time and energy, the drawback that operating characteristics is low greatly reduces operator's labour intensity.
● as above-mentioned structure of the present utility model, because the utility model comprises the force feedback control system, accept the control signal of control hand input by the force servo controller in the force feedback control system, it exports control signal to driver in real time according to the size and Orientation of the power that the operator applies on the pull pressure sensor of control hand, the work of driver drives motor, the running of motor drives manipulator body.So the force feedback control system makes electric manipulator have accurate positioning in control, be quick on the draw, response is fast, does not have to lag behind, and motion does not steadily have the advantage of impacting shake.The conventional robot that had both solved push button control in the prior art needs repeatedly the location difficulty problem that exists in the inching button control, has solved the conventional robot that adopts potentiometer control again because the location that machine driving and wearing and tearing cause is inaccurate and there is the problem that lags behind in response.
● as above-mentioned structure of the present utility model, because the force feedback control system in the utility model electric manipulator can be to be electrically connected with being connected of control hand, or the communication connection, promptly control hand and can select the installation site flexibly.When need be when some be not suitable for working site that operating personnel enter and use electric manipulator to implement lifting operation, the operator can pass through the long-range input control order of control hand away from the working site, promptly send the force feedback control system to by wireless transmission, the action of control electric manipulator, improve operator's safety coefficient in use, ensured the safety of the person and equipment.
