Technical Field

The utility model relates to the technical field of robot, concretely relates to bionical software tongs.

Background

In the application field of the existing robot, a manipulator is often required to be used for grabbing an object, the manipulator which is composed of rigid substances is mostly adopted at present, the rigid substances have many defects in actual production, and rigid contact easily damages the surface of the object. In addition, the surface of the rigid manipulator is smooth, so that the rigid manipulator is not easy to grab and is easy to generate the phenomenon that an object slides off.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned damageable quilt that current manipulator exists and snatch unstable problem, the utility model provides a bionical software tongs, simple structure makes things convenient for easy-to-use, and the design of software has reduced the damage to the object surface, and it is better to snatch the effect, snatchs more firmly.

In order to solve the technical problem, the utility model provides a following technical scheme:

a bionic soft gripper comprises an outer shell, a first cavity, a second cavity and a sucker with a through hole; the shell body is including setting up the portion of absorbing and setting up the flexion at relative opposite side in its one side, first cavity sets up the inside of portion of absorbing, the second cavity sets up the inside of flexion, the sucking disc sets up the surface of portion of absorbing, first cavity with the sucking disc is linked together, first cavity is connected with outside air pump, the second cavity is connected with outside air supply, first cavity with do not communicate between the second cavity. The utility model discloses a bionical design has designed a software tongs similar with squid claw, and the design of software can prevent well to the damage of being snatched the thing surface, makes the flexion crooked through ventilating for the second cavity, absorbs first cavity through the air pump and makes the sucking disc firmly absorb and snatch the thing, can firmly snatch the object more, snatch the effect better.

Further, the surface of flexion is provided with the bending ditch, can let the flexion better crooked, makes the portion of absorbing adsorb on the object surface better simultaneously, snatchs the object more firmly.

Furthermore, the bending groove is used as a dividing line, the bending part is divided into a plurality of bending block bodies, block cavities are formed in the bending block bodies and communicated with the second cavity, the bending effect of the bending part is enhanced, the suckers on the suction part are better attached to the surface of an object, and the grabbing effect is better.

Furthermore, the shape of the outer shell is a cone, so that the outer shell is more flexible to bend, the design of the cone has better adaptability, and the outer shell is more convenient to use.

Further, the material of shell body is silica gel, and the damage to snatching the thing surface that has significantly reduced has certain antiskid effect again simultaneously to the damage of snatching the thing surface, makes to snatch more firmly.

Furthermore, the surface of the suction part is also provided with anti-skid protrusions, so that the anti-skid effect is improved, the grabbing is firmer, and the object is prevented from sliding down better.

Compared with the prior art, the utility model discloses following beneficial effect has:

simple structure is ingenious, and centre gripping object in-process removes to realize encircleing and press from both sides tight object for the flexion through aerifing, and the shrink is breathed in to the sucking disc simultaneously, improves the crookedness of clamping jaw, and the sucking disc can adsorb the object simultaneously, promotes the reliability that adsorbs and snatch, adsorbs to snatch the ability stronger, and the damage to the object surface that has also significantly reduced moreover, and the security is higher, and the reliability is higher, and the practicality is better.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
