Description

Technical Field

[0001] The invention relates to the field of iron and steel metallurgy, and in particular to a manipulator grasping claw with a wear-resistant nano coating. Background Art

[0002] The robot gripping claw is the front end of the robot used to grasp objects. It needs to constantly contact and rub against the surface of the object during the operation of the robot. After long-term use, the surface coating of the claw will wear out, resulting in the inability to control the distance between the claws and the gripping force when the claw grasps, making the process of grasping objects unstable, and even causing the risk of the grasped objects falling. Summary of the invention

[0003] The object of the present invention is to provide a robot gripper with a wear-resistant nano-coating to solve one or more of the above-mentioned problems in the prior art.

[0004] The present invention provides a manipulator grasping gripper with a wear-resistant nano coating, wherein the gripper is provided with a nano coating, and the nano coating comprises a primer layer and a metal coating which are sequentially coated from the inside to the outside.

[0005] In some embodiments, the primer layer is made of nickel-based powder.

[0006] In some embodiments, the nickel-based powder uses metal as a binder phase.

[0007] In some embodiments, the nickel-based powder is nickel-based alumina or nickel-based chromium.

[0008] In some embodiments, the metal coating is nano-tungsten carbide.

[0009] In some embodiments, the metal coating is formed by plasma spraying.

[0010] The advantages of the manipulator gripper with a wear-resistant nano-coating described in the present invention are: The nano coating on the gripper is wear-resistant, and coating the gripper with a base layer before spraying the nano tungsten carbide effectively solves the problem of difficult to achieve effective spraying of nano-scale tungsten carbide on the gripper in the existing process.

DETAILED DESCRIPTION

[0012] In order to further clearly explain the purpose, technical solutions and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings. The accompanying drawings of the present invention are for the purpose of simple and easy-to-read structural framework diagrams and cannot limit the true purpose of the present invention.

[0013] Combination Figure 1 and Figure 2 As shown in the content, in this embodiment, a robot gripping claw with a wear-resistant nano-coating is proposed, and a plurality of claws 2 are arranged at one end of the robot 1. The claws 2 include a main body 201 and a nano-coating. The nano-coating includes a base layer 202 and a metal coating 203 coated in sequence from the inside to the outside, and the base layer 202 is coated on the main body 201.

[0014] In some specific implementations, the base layer 202 uses nickel-based powder, and the nickel-based powder uses metal as a bonding phase, wherein the nickel-based powder is nickel-based aluminum oxide or nickel-based chromium.

[0015] The metal coating 203 may be nano-tungsten carbide and may be formed by plasma spraying.

[0016] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several similar modifications and improvements without departing from the creative concept of the present invention, and these should also be regarded as the protection scope of the present invention.
