Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mechanical hands, and particularly relates to an intelligent industrial mechanical hand. BACKGROUND

[0002] With the continuous development of the robot industry in China, the technology and research field has reached a certain level, and the industrial robot technology has also developed rapidly. Traditional industrial robots generally include a base, a rotating arm, a large arm and a small arm. At present, in the field of industrial automation and intelligent manufacturing, the load capacity and precision of robots are required to be higher and higher. Due to the structural limitation of traditional industrial robots, there are limitations in load capacity and working space.

[0003] Some invention patents in the technical field of mechanical hands are disclosed in the prior art. The invention patent with the publication number CN118990592B discloses an anti-skid mechanical claw for an industrial mechanical hand, and relates to the technical field of mechanical claws. Due to the inertia of the weight of the object, there is a tendency for the object to slide down between the object and the mechanical claw, so that the object falls off when being clamped and lifted. The anti-skid mechanical claw for the industrial mechanical hand cooperates the inclined surface block with the outer inclined plate, so that when the clamping plate is lifted after clamping the object, the friction between the clamping plate and the object is used to transmit the tendency to the inclined surface block and the connecting rod through the clamping plate when the object tends to slide down, so that the connecting rod and the inclined surface block simultaneously tend to slide down. The inclined surface of the outer inclined plate is adapted to the sliding of the inclined surface block. After the tendency to slide down appears, the clamping force of the clamping plate to the inner side is increased to limit the sliding of the object and prevent the object from sliding off during the movement of the clamped object. However, the technical scheme still has some deficiencies in the process of use. Since the small arm is relatively slender compared with the main structure of the mechanical arm, and directly bears the end effector and the weight grasped by the end effector, the small arm bears greater stress and wear compared with the main structure of the mechanical arm, so the wear speed of the small arm is also faster. When the small arm grasps the weight through the end effector, mechanical failure is prone to occur.

[0049] The embodiment is characterized in that: the heavy object is grabbed by the mechanical arm body, the small arm 2 and the end effector 3, and the heavy object is transported, in the process of transporting the heavy object, the small arm 2 is relatively thin relative to the mechanical arm body, and directly bears the end effector 3 and the heavy object grabbed by the end effector 3, so that the small arm 2 is more quickly worn relative to the mechanical arm body, when the small arm 2 is mechanically out of control by grabbing the heavy object through the end effector 3, the end effector 3 and the heavy object will drive the other end of the small arm 2 to rotate downward on the inner side of the end of the mechanical arm body at a high speed, in the initial stage, the compensation shaft 505 pulls the plurality of adapter sleeves 801 through the plurality of adapter sleeves 801 rotatably installed on the inner side, the other end of the steel wire rope 803 is gradually separated from the winding wheel 404 under the action of the tension, and the winding wheel 404 drives the winding shaft 403 to rotate in the winding box 401, in the process, on the one hand, the winding shaft 403 twists the winding spring 405 to be elastically deformed, and on the other hand, the winding shaft 403 drives the plurality of ratchet gears 602 to synchronously rotate through the plurality of combined sleeves 601, the active pawl tooth 6046 does a large amplitude centrifugal motion in the process of rapidly rotating, the active pawl tooth 6046 rotates in the inner side of the two safety plates 6041 through the safety shaft 6042, and twists the adapter spring 6044 to be elastically deformed, after the active pawl tooth 6046 rotates by a certain angle, the active pawl tooth 6046 is blocked by the limiting plate 6045, at this time, the active pawl tooth 6046 stops rotating, when the active pawl tooth 6046 is connected with the passive pawl tooth 705, the active pawl tooth 6046 pushes the arc-shaped sliding plate 704 through the passive pawl tooth 705, the arc-shaped sliding plate 704 slides in the arc-shaped sliding groove 702 through the arc-shaped sliding block, and presses the arc-shaped spring 703 to be elastically deformed, the arc-shaped sliding plate 704 slides through the limiting seat 7061 to drive the limiting shaft 7062 to slide in the push top hole 7064, the clamping tooth 7063 is driven by the limiting shaft 7062 to rotate through the rotating shaft 7065, until the clamping tooth 7063 is engaged with the ratchet gear 602, at this time, the plurality of ratchet gears 602 stop rotating under the action of the plurality of clamping teeth 7063, since the plurality of ratchet gears 602 are fixedly connected with the winding shaft 403 through the plurality of combined sleeves 601, the winding shaft 403 also stops rotating, and the part of the steel wire rope 803 wound on the winding wheel 404 cannot be released, at this time, the plurality of steel wire ropes 803 pull the compensation shaft 505 through the plurality of adapter sleeves 801, the compensation shaft 505 pulls the piston disc 506 to slide in the compensation tank 501, and pulls the compensation spring 507 to be elastically deformed, when the piston disc 506 is connected with the limiting ring 508, the piston disc 506 cannot slide in the compensation tank 501, the plurality of steel wire ropes 803 generate a pulling force on the small arm 2, so that the small arm 2 can rotate downward at a large amplitude when the small arm 2 is mechanically out of control, and the small arm 2, the end effector 3 and the heavy object are prevented from being damaged by the inertia impact on the mechanical arm body.

[0050] Specifically, each of the plurality of execution clamps of the end effector 3 is connected with an antiskid pad 9, the antiskid pad 9 is a hollow joint body, the plurality of antiskid pads 9 located on one side are communicated through a combination pipe 11, one antiskid pad 9 located on one side is communicated with a vacuum pipe 10, and the other end of the vacuum pipe 10 is communicated with the compensation tank 501.

[0051] Specifically, in the process that the piston disc 506 is pulled by the compensation shaft 505, the suction pipe 502 is controlled to be high-frequency on-off by the electromagnetic valve 503, when the electromagnetic valve 503 is in the closed state, the compensation tank 501 cannot suck air through the suction pipe 502, the compensation tank 501 sucks air through the vacuum pipe 10 by using the suction holes opened on the surface of the antiskid pad 9, since the antiskid pad 9 is connected with the weight, the suction holes are in the blocked state, and thus the suction holes can generate suction force on the weight, when the electromagnetic valve 503 is in the open state, the suction pipe 502 is in the conducting state, the compensation tank 501 sucks air through the suction pipe 502, and the suction force at the suction holes gradually weakens, so that the law is continuously circulated, the resistance of the antiskid pad 9 to the weight can be effectively increased, and thus the weight can be prevented from falling to a certain extent.

[0052] Working principle, in use:

[0053] When the heavy object is controlled to be grabbed and carried by the mechanical arm, the mechanical arm body, the forearm 2 and the end effector 3 work cooperatively, however, in the process of carrying the heavy object, since the forearm 2 is more slender relative to the mechanical arm body structure, and directly bears the end effector 3 and the heavy object grabbed by the end effector 3, the forearm 2 bears greater stress and wear compared with the mechanical arm body, and thus the wear speed of the forearm 2 is faster, when the heavy object is grabbed by the forearm 2 through the end effector 3, if mechanical out-of-control occurs, the end effector 3 and the grabbed heavy object will drive the other end of the forearm 2 to rotate downward on the inside of the end of the mechanical arm body, at this time, the compensation shaft 505 starts the emergency protection mechanism:

[0054] In the initial stage, the compensation shaft 505 pulls the plurality of steel wire ropes 803 through the linkage components mounted inside the plurality of adapters 801, and under the action of the pulling force, the other end of the steel wire rope 803 gradually separates from the winding wheel 404, and the winding wheel 404 drives the winding shaft 403 to rotate in the winding box 401. In this process, on the one hand, the torsional force of the winding shaft 403 causes the winding spring 405 to elastically deform and store elastic potential energy, and on the other hand, the winding shaft 403 drives the plurality of ratchet gears 602 to rotate synchronously through the plurality of combination sleeves 601. When the ratchet gears 602 rotate rapidly, the active teeth 6046 thereon produce a large amplitude centrifugal motion due to the centrifugal force, and the active teeth 6046 rotate inside the two safety plates 6041 through the safety shaft 6042, while twisting the adapter spring 6044 to cause it to elastically deform. When the active teeth 6046 rotate to a certain angle, they will be stopped by the limiting plate 6045, and then when the active teeth 6046 are docked with the passive teeth 705, the active teeth 6046 push the arc-shaped sliding plate 704 through the passive teeth 705. The arc-shaped sliding plate 704 slides in the arc-shaped sliding groove 702 through the arc-shaped sliding block, and exerts pressure on the arc-shaped spring 703 to cause it to elastically deform. In the sliding process of the arc-shaped sliding plate 704, it drives the limiting shaft 7062 to slide in the push-up hole 7064 through the limiting seat 7061, and under the pushing of the limiting shaft 7062, the clamping teeth 7063 rotate through the rotating shaft 7065 until meshing with the ratchet gears 602. At this time, the plurality of ratchet gears 602 stop rotating under the restriction of the plurality of clamping teeth 7063, and since the plurality of ratchet gears 602 are fixedly connected with the winding shaft 403 through the plurality of combination sleeves 601, the winding shaft 403 also stops rotating. At the same time, the steel wire rope 803 wound on the winding wheel 404 cannot be released, and at this time, the plurality of steel wire ropes 803 exert a pulling force on the compensation shaft 505 through the plurality of adapters 801, and the compensation shaft 505 pulls the piston disc 506 to slide in the compensation tank 501 and stretches the compensation spring 507 to cause it to elastically deform. When the piston disc 506 slides to contact the limiting ring 508, the piston disc 506 cannot continue to slide in the compensation tank 501, and at this time, the plurality of steel wire ropes 803 generate a stable pulling force on the small arm 2, effectively limiting the large amplitude downward rotation of the small arm 2 when the small arm 2 loses control.

[0055] In the process of the piston disc 506 being pulled by the compensation shaft 505, the high-frequency on-off operation of the suction pipe 502 is realized by precisely controlling the electromagnetic valve 503. When the electromagnetic valve 503 is in the closed state, the air flow passage between the compensation tank 501 and the suction pipe 502 is cut off, at this time, the compensation tank 501 cannot suck the external air through the suction pipe 502, and the compensation tank 501 instead sucks the air through the vacuum pipe 10 and the suction hole pre-opened on the surface of the anti-skid pad 9. Since the anti-skid pad 9 is tightly connected with the weight, the suction hole is effectively blocked by the weight, thereby forming a negative pressure at the suction hole and generating a stable suction force on the weight. When the electromagnetic valve 503 is switched to the open state, the suction pipe 502 is in the conducting state, and the compensation tank 501 can quickly suck the external air through the suction pipe 502, so that the air pressure in the compensation tank 501 gradually rises, the negative pressure at the suction hole decreases, and the suction force also gradually decreases. According to the law of the closing and opening of the electromagnetic valve 503, the suction force at the suction hole can be continuously and dynamically adjusted, and the frictional resistance between the anti-skid pad 9 and the weight can be effectively increased.

[0056] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
