AI Technical Summary

Technical Problem

Existing robotic end effector grippers suffer from insufficient suction force and unstable gripping when gripping cylindrical products. The large size of the gripper also results in a small amount of material gripped per unit area, leading to low work efficiency.

Method used

Design a vacuum flexible support plate, including a support plate body and support claws. The support claws are opened up inside the object being grasped by using negative pressure. The gripping area is increased by the deformation of the support claws, and the friction is enhanced by the anti-slip grooves of the support claws to prevent them from falling off.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of robot end gripping accessories, in particular to a vacuum flexible supporting disc. BACKGROUND

[0002] Some existing robot end gripping accessories adopt suction cups or gripping discs. The working principles of the suction cup and the gripping disc are similar. Both of them realize the action of suction or gripping by using air pressure. The vacuum formed by atmospheric pressure generates a certain pressure difference. The vacuum degree is used to maintain the adhesion of two objects so that they do not separate. In industry, the suction cup or the gripping disc is used to realize the "take" and "put" in the process of carrying and moving, and to realize automation and mechanization.

[0003] When some cylindrical products are gripped, the suction cup is used to suck and grip at the top of the product. The suction force and the gripping force are weak, and the product is not easy to be gripped or falls off during the gripping process. The gripping disc needs to wrap the product for gripping. Therefore, the volume of the gripping disc is required to be greater than that of the gripped product. The gripping amount in unit area is small, and the work efficiency is low. Therefore, there is an urgent need for a component or device that can solve such problems. SUMMARY

[0004] The purpose of the present application is to provide a vacuum flexible supporting disc with a unique structure design to improve the gripping amount in unit area by supporting and opening the inside of the gripped object.

[0005] To achieve the above purpose, the following technical scheme is adopted: a vacuum flexible supporting disc, comprising a supporting disc body 1 and a supporting claw 2. The supporting disc body 1 is a cylindrical structure with closed ends. A chamber 11 is arranged in the inside of the supporting disc body 1. An air vent 12 is arranged on the top wall of the supporting disc body 1. The supporting claw 2 is arranged on the outer side wall of the supporting disc body 1. The bottom wall 13 of the supporting disc body 1 is a soft bottom surface. The bottom of the supporting claw 2 is fixedly connected with the bottom wall 13. The supporting claw 2 is an L-shaped supporting claw. The L-shaped side of the supporting claw 2 is a supporting and opening part 21. The L-shaped bottom of the supporting claw 2 is a connecting part 22. The bottom wall 13 is a soft arc surface protruding outward. The top surface of the connecting part 22 is an arc surface matching the bottom wall 13. The top surface of the connecting part 22 is fixedly connected with the bottom surface of the bottom wall 13.

[0006] A anti-skid groove 211 is arranged on the side of the supporting and opening part 21 away from the supporting disc body 1.

[0007] A pneumatic connector connecting piece 14 is arranged in the air vent 12. The pneumatic connector connecting piece 14 is sealingly connected with the inner wall of the air vent 12.

[0008] The supporting disc body 1 and the supporting claw 2 are integrally formed by silicone injection molding.

[0009] Four supporting claws 2 are evenly arranged on the outer circumferential side of the supporting disc body 1.

[0010] After the above technical scheme is adopted, the device has the advantages of simple structure, low processing cost, material saving, small size, flexible deformation, and the like. BRIEF DESCRIPTION OF DRAWINGS

[0018] The specific embodiment of the present application is as follows: referring to Figures 1-5As shown, a vacuum flexible support disc includes a support disc body 1 and a support claw 2, the support disc body 1 is a closed cylinder structure, the inside of the support disc body 1 is provided with a chamber 11, the top wall of the support disc body 1 is provided with a vent hole 12, the vent hole 12 communicates the chamber 11 with the outside, the support claw 2 is arranged on the outer side wall of the support disc body 1, the bottom wall 13 of the support disc body 1 is a soft arc surface protruding outward, the support claw 2 is an L-shaped support claw, the L-shaped side of the support claw 2 is a support opening part 21, the L-shaped bottom of the support claw 2 is a connecting part 22, the top surface of the connecting part 22 is an arc surface matched with the bottom wall 13, the top surface of the connecting part 22 is fixedly connected with the bottom surface of the bottom wall 13, the soft bottom wall 13 is easy to deform when subjected to negative pressure, the arc surface increases the deformation range of the bottom wall 13, when supporting the grabbed object, the connecting part 22 of the support claw 2 gathers to the center of the arc bottom wall 13 along with the deformation of the arc bottom wall 13, the top of the support opening part 21 of the support claw 2 is outwardly supported, the greater the deformation range of the arc bottom wall 13, the greater the support opening range of the support opening part 21.

[0019] Four support claws 2 are evenly arranged on the outer circumferential surface of the support disc body 1, the four support claws 2 ensure the uniformity and stability of the force in four directions.

[0020] The vent hole 12 is provided with a pneumatic connector connecting piece 14, the pneumatic connector connecting piece 14 is sealingly connected with the inner wall of the vent hole 12, a pneumatic connector is screwed on the pneumatic connector connecting piece 14, and the pneumatic connector is connected with a negative pressure vacuum pump through an air pipe.

[0021] In use, the support disc is suspended in the grabbed object, the negative pressure pump is turned on, the negative pressure is formed in the chamber 11, the arc bottom wall 13 of the support disc body 1 is deformed due to the internal negative pressure, and the arc bottom wall 13 changes from outward protrusion to inward depression, thereby driving the bottom wall of the connecting part 22 to move to the center of the bottom wall 13, making the top of the support opening part 21 of the support claw 2 away from the support disc body 1 and abutting against the inner wall of the grabbed object, so that the grabbed object is abutted and suspended on the outer side of the support claw 2, and the grabbed object is moved to the required position along with the movement of the support disc, the negative pressure vacuum pump is turned off, and the grabbed object is dropped to complete a grabbing work.

[0022] The top end of the support claw 2 is one end of the support claw 2 for grabbing the object, the top end of the support claw 2 is provided with an anti-skid groove 21 on the side away from the side wall of the bottom disc part 12, after the support claw 2 supports the inner wall of the grabbed object, the anti-skid groove 21 can increase the friction between the support claw 2 and the inner wall of the grabbed object, effectively preventing the grabbed object from falling off.

[0023] The support disc body 1 and the support claw 2 can be integrally formed by silicone injection molding, and the injection molding makes the processing more convenient, or the support disc body 1 and the support claw 2 can be separate and bonded together by glue.

[0024] The device has the advantages of simple structure, low processing cost, material saving, small size, flexible deformation, increased number of grabbing in unit area by installing the supporting disc at the end of the mechanical arm, and improved work efficiency.
