Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in the technology of this area
Personnel are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, it is also possible to make some changes and improvements.These broadly fall into the present invention
Protection domain.
The gas control gasbag-type software mechanical arm that the present invention provides, it can be bled by filling of its inner balloon parts 2
Change the shape of main body, it is thus possible to the obstacle easily avoided in environment specifies position to carry out associative operation to arrive.Mechanical arm
Airbag components 2 is fixed on the medial wall of mechanical arm software silica gel shell 1 by silica gel solid locking member 5, and every airbag components 2 is by 10 balls
Capsule 7 is connected to form, and all has a thicker falope ring 6 to bind round, so that airbag components 2 can only be in length side outside each sacculus 7
Upwards stretch, it is ensured that the repeatable contractility that mechanical arm is good;Adjacent sacculus 7 catch cropping ventilation treatment, as
Sacculus air flue 8, it is provided that the flexible of mechanical arm.It is arranged side by side to software silica gel enclosure is triangular in shape by air pump
Airbag components 2 is inflated or bleeds, and directly changes airbag components 2 deformation in the longitudinal direction, even if airbag components 2 is carried out
Longitudinal extension, and then indirectly change the curved shape of software mechanical arm, to adapt to environment.By to three balloon portion arranged side by side
Part 2 is made different inflations of taking out and is processed, and whole software mechanical arm can be made to reach required bending direction and degree of crook.
Further, the corrugated tube that software silica gel shell is made up of soft silica gel, making whole mechanical arm is soft material,
And certain shape can be kept during bending without rebounding, and enough flexible sky can be provided to air bag
Between, meet overall motility.Described cell parts has two joints, each joint to have three air bag placements arranged side by side triangular in shape, often
One end of root air bag is fixed on housing interior side-wall, and the other end connects trachea, and inflation of bleeding can make air bag shorten or elongation.Institute
The balloon portion stated, between sacculus, connecting place has made ventilation treatment, and between sacculus, contact area is less, and air bag can be made vertical overall
Flexible is ensure that on the premise of flexible.Described balloon portion side all has the falope ring of suitable rugosity to carry out horizontal chi
Fixing of degree, it is ensured that the entirety of air bag can only longitudinal extension.Described air pump device is fixed in mechanical arm outside platform, connects
Trachea, to air bag, can control the inflation/deflation of air bag at any time.The silica gel block connection of described air bag and shell ensure that this
Repeatability that mechanical arm is flexible and controllability.
More specifically, the present embodiment offer is a kind of can be with the gas control gasbag-type software mechanical arm of obstacle changes shape.As
Shown in Fig. 1, including: software silica gel shell 1, it is equivalent to the main part of software mechanical arm;Airbag components 2, it is whole machine
The core component of mechanical arm deformation, fixes on the sidewall in the enclosure of its two ends with silica gel;Trachea parts 3, it provides gas for air bag
Passage;Base member 4, supports and fixes whole mechanical arm.
Airbag components 2, is to be formed by the perfusion of autogamy silica gel, is inflated by trachea 3 and air pump (not shown) or is bled,
In airbag components 2, all there is a falope ring 6 each sacculus 7 side, is used for limiting the telescopic direction of sacculus 7, i.e. only at balloon portion
Stretch on the direction vertical with falope ring of part 2, the elongation of airbag components 2 entirety can be realized by this control mode
And shortening.Airbag components 2 and software silica gel shell 1 are by the head of airbag components 2 and afterbody are passed through bulk silica gel with soft
Body silica gel shell 1 medial wall adhesion is attached and fixes.Three arranged side by side airbag components 2 in software silica gel shell 1 in etc.
Limit Triangle-Profile, every airbag components 2 is controlled by different air pumps respectively, so can stretching by airbag components 2
Drive the flexible of whole mechanical arm and bending.Additionally the design of the catch cropping of sacculus 7 ventilation, gets through work between adjacent sacculus 7
For sacculus air flue 8, so can ensure that airbag components 2 air pressure inside communicates controlled, again can be in the situation of mechanical arm bending
Under can follow and slightly bend, in order to avoid inside extrudes mutually conflict.
When running into the situation needing to avoid obstacle, by trachea 3 to two the front end gas relative with expectation direct of travel
Capsule parts 2 are inflated, and two airbag components being inflated extend because of sacculus 7 longitudinal dilatation, but inflated same layer
Another airbag components then do not changed current elongation, then the software silica gel shell 1 of mechanical arm because of not inflating
To inflated air bag one side bending, show as changing current direct of travel incision expectation direct of travel, it is achieved avoid obstacle
Thing.If barrier size is big compared with mechanical arm, then then need in mechanical arm front end with barrier change of shape cut-through
After thing, three piece air bags post-brachial to machinery realize similar operation.
Trachea 3 is scheduled on software silica gel shell 1 and base member 4 by silica gel solid also with airbag components 2.
In order to the most do not affect position and the form of obstructing objects, the gas control gasbag-type software machine that the present invention provides
The body that mechanical arm has because of its unique shell mechanism software silica gel shell and control mode gas control can deformation behavior, body deformation can
Control property, body deformation promptness and kinematic dexterity, it is possible to effectively and with obstacle changes shape thus effectively realize in time
Reduce the impact of position on obstacle own while hiding obstacle as far as possible or produce compressional deformation.
Below, in conjunction with above-mentioned robot arm device, its attainable function is illustrated.
A kind of function that the present embodiment provides is to arrive to specify position.If specify position mechanical arm head just before
End, can be by carrying out the inflation of same degree to front and back end two-layer airbag components 2 by trachea 3, and sacculus 7 longitudinal dilatation makes soft
Body silica gel shell 1 extends thus the head of mechanical arm can arrive appointment position.If appointment position is in the side of mechanical arm, then
Needing by being inflated the 2 of mechanical arm front end airbag components 2 by trachea parts 3, another root air bag keeps certain journey
Degree is bled, so that two inflated airbag longitudinal dilatations, it is possible to the direction towards another root air bag bends, thus arrives
Reach appointment position.Air bag is flexible with driving mechanical brachiocylloosis as shown in Figure 4.
The another kind of function that the present embodiment provides is to realize more extension merit by the parts of increase mechanical arm leading head
Energy.The function provided according to embodiment arrives specifies position.Some parts can be added as required at mechanical arm leading head
Afterwards to specifying position to realize specific operation.As add in mechanical arm front end photographic head can arrive appointment position examine this position
Real-time condition;Plus thermometal can be added, appointed part is carried out burn off operation etc..
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or revise, this not shadow
Ring the flesh and blood of the present invention.In the case of not conflicting, the feature in embodiments herein and embodiment can any phase
Combination mutually.
