Flexible gripper with two fingers of the present invention is driven gear wheel 112 rotations and is passed to leading screw 106 by meshing with pinion 111 rotatablely moving by motor 103, so also and then rotation of leading screw 106, makes the assembly that horizontally slips do move toward one another.The right-hand man's finger assembly that is hinged on the assembly that horizontally slips is also done move toward one another.When right-hand man's finger assembly after certain distance begins to contact object with the clamping of wanting, right-hand man's finger assembly is still done move toward one another, this moment, clamping force constantly increased, and compressed the spring fore-set on the slide assemblies; When clamping force reaches setting value, the potentiometer output signal on right-hand man's finger assembly, single-chip microcomputer judges that the back disconnects the power supply of motor 103, motor shuts down, the clamping end of job.The present invention is simple in structure, dexterous, reliable in function, and chucking power is big, and the size of monitoring force is stepping up to stop to step up action when power reaches certain numerical value automatically, has reached the function that protection steps up object.This mechanism can be used in the automated job in fields such as machinery, biology, chemical industry, environmental protection and pharmacy.
Flexible gripper with two fingers of the present invention is provided with two location status: i.e. initial position and current location; Be provided with three kinds of motion states: i.e. reset mode, closure state and open configuration.
Initial position: be meant residing position when the clamper clamping range is maximum, and be used to write down a mark that resets when clamper starts at every turn, and as calculating the basic point of left hand finger assembly 5 with right hand finger assembly 3 displacements;
Current location: be meant the position of clamper after the absolute distance that initial position moved.
Reset mode: be meant that flexible gripper records two left slide assemblies 4 and right slide assemblies 6 by Hall element 9 and whether is in initial position and carries out adjustment and make it be in this motion state of initial position.When left hand finger assembly 5 and right hand finger assembly 3 are not in initial position, then Hall element 9 sends signal, rotate by Single-chip Controlling motor 103, by motor 103 through gear wheel 112, pinion 111, thereby drive leading screw 106 motions, the left slide assemblies 6 that is installed on the leading screw 106 is done from motion when Hall element 9 sends the signal of left hand finger assembly 5 and right hand finger assembly 3 arrival initial positions with right slide assemblies 4, and Single-chip Controlling motor 103 stops operating.
Closure state: be meant the motion state when flexible gripper is in right slide assemblies 4 and left slide assemblies 6 and does the move toward one another grip objects.When wanting the clamping object, single-chip microcomputer will be controlled motor 103 and rotate, by motor through gear wheel 112, pinion 111, thereby drive leading screw 106 motions, make the left slide assemblies 6 and the right slide assemblies 4 that are installed on the leading screw 106 make move toward one another, up to measure be clamped to object do not have folder partially, folder is empty and during with the power that sets big or small identical, Single-chip Controlling motor 103 stops operating.
Open configuration: be meant that flexible gripper is in right slide assemblies 4 and left slide assemblies 6 and does motion state when object is unclamped in motion.When needs unclamp object, rotate by Single-chip Controlling motor 103, by motor through gear wheel 112, pinion 111, thereby drive leading screw 106 motions, the left slide assemblies 6 that is installed on the leading screw 106 is done from motion with right slide assemblies 4, and Single-chip Controlling motor 103 stops operating when unclamping object up to measuring.
Flexible gripper with two fingers of the present invention in working order down, after powering on, promptly begin to enter reset mode, purpose is to make right hand finger assembly 3 and left hand finger assembly 5 get back to initial position, so that clamping range reaches maximum, and set up the basic point that calculates displacement and do reference during for the clamping object.Reset after the end, clamper just enters closure state, comes the clamping object.When grip objects, closure state finishes, but if there is not grip objects (folder sky or folder are partially), then returns reset mode, carries out closing motion again after finishing when resetting.When the object needs were released, then clamper entered open configuration, and after open configuration finished, clamper entered reset mode again automatically.
In the present invention, the movement relation of (referring to shown in Figure 7) flexible gripper with two fingers (reset, closed and open) control realizes a communication (drive circuit and SCM system are installed on and refer to that 1 interior) by one drive circuit and SCM system.Drive circuit is controlled motor 103 in real time by single-pole single-throw(SPST relay J 1 and dpdt relay J2, and receives the armature current signal f of motor 103 outputs
