The sealing telescopic rod 8 can translate in the hanging rail 1 along with the movement of the mechanical claw 5, when the mechanical claw 5 moves to a grabbing point, a friction pad 23 is attached to the connecting surface of the hanging rail 1 and the sealing telescopic rod 8 at the moment, along with the movement of the mechanical claw 5, the side surface of the sealing telescopic rod 8 can contact and rub with the friction pad 23, as the whole mass of the mechanical claw 5 is supported by two guide wheels 6, the sealing telescopic rod 8 rotates, the steel rope 19 is wound up by the rotation, so that the thin rod 14 is pulled upwards by pulling the steel rope 19, the folding effect of the clamping jaw 16 is completed, then along with the movement of the mechanical claw 5, the friction pad 23 continuously provides a rotating trend for the sealing telescopic rod 8, the sealing telescopic rod 8 is ensured not to be reversed until the mechanical claw 5 moves to a throwing point, the position of the friction pad 23 is replaced, the sealing telescopic rod 8 is reversed in the advancing process of the mechanical claw 5, so that the steel rope 19 is released, and the workpiece is smoothly thrown under the action of gravity, the workpiece is required to be transported by a conveyor belt, and in this way, the workpiece and the relative static grabbing stability of the mechanical claw 5 can be ensured in the releasing and grabbing process;
In order to ensure the grabbing firmness of the workpiece, when the mechanical claw 5 grabs the workpiece, the guide component stretches the top of the sealing telescopic rod 8 along with the movement of the mechanical claw 5, so that a cavity and negative pressure are generated on the inner side of the sealing telescopic rod 8, the negative pressure is transmitted to the sucker 21 through the negative pressure pipe 18, so that negative pressure is generated at the bottom, when negative pressure is generated, the three clamping claws 16 grab the workpiece, the top of the workpiece is attached to the bottom of the attaching seat 15, the workpiece can be effectively attracted by the attractive force, the firmness of grabbing the workpiece is improved, the workpiece cannot fall off easily in the moving process, the workpiece cannot shake due to the adsorption type fixation, noise in the transporting process is reduced, the sealing telescopic rod 8 is shortened after the workpiece is transported to a destination, the internal negative pressure disappears, and meanwhile the clamping claws 16 are loosened, so that the workpiece can fall normally;
When the mechanical claw 5 moves to a grabbing place, along with the movement of the mechanical claw 5, the top hook 17 moves upwards under the guide of the upward bulge at the top of the guide plate 7, so that the inner rod is pulled out upwards, negative pressure can be generated in the outer sleeve of the sealing telescopic rod 8 and is transferred into the attaching seat 15 through the negative pressure pipe 18, so that the effect of adsorbing a workpiece is realized, when the mechanical claw 5 moves to a throwing destination, the top of the guide plate 7 is downwards concave, the top hook 17 and the inner rod slide downwards under the action of gravity, so that the internal negative pressure disappears, the workpiece can be smoothly put down, through the arrangement and the clamping arrangement of the mechanical claw 5, the effect of fully automatically grabbing the workpiece and conveying the workpiece is realized, the whole grabbing and releasing process is controlled through a mechanical structure, no electric appliances such as a motor are required, the error rate of the whole process is low, and the whole part can be transported for a long time;
The arrangement of the serial arms 9 enables the overall gravity center of the serial arms 9 to deviate outwards, so that the serial arms 9 cannot contact with the driving roller 3, and mutual interference among parts is reduced;
the movement path of the steel cable 19 is limited by the connector 10 and the serial arm 9, so that other parts are reduced to be influenced in the movement process;
The negative pressure tube 18 can change the shape due to the lifting of the attaching seat 15, and the negative pressure tube 18 can be coiled into a spiral shape when the negative pressure tube 18 is loosened by matching with the design of an elastic spiral sleeve, so that interference to other parts in the deformation process of the negative pressure tube 18 is reduced;
The elastic material at the bottom of the sucker 21 can deform when contacting a workpiece, so that the correct transmission of suction force is ensured, and the arrangement of the balls can reduce the friction force of the guide plate 7 and the top hook 17.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
