Problems solved by technology

However, this method needs to strip all the wires in all the cables passing through the rotary joint and connect them to separate sleeve rotating devices, which destroys the structure of the cables themselves, and the cost of the device is relatively high. Moreover, this The method is only suitable for the case where the number of wires is small. If the number of wires is large, it is unrealistic to use this method

Embodiment Construction

[0037] The anti-winding device includes several passive rotating components and requires a certain length of cables. Several components can be superimposed as needed, and generally no less than 3 components are used. Typical use cases like figure 1 shown.

[0038] passive rotating assembly

[0039] The passive rotating assembly is the core part of the present invention. The component is connected with the joint of the robot, and the connected component 1 is fixed at the joint of the robot, and there is a corresponding mechanical structure to ensure that the two components do not disengage. The mutual rotation between the two is guaranteed to be smooth by means of lubrication or bearing connection. If the joints of the robot are inconvenient to change, the component 1 can also be fixed on the joints of the robot so that they cannot move relative to each other. The cables that need to rotate with the joint pass through the component through the through hole in the middle o...

Abstract

The invention provides a winding preventing device for a rotation joint of a robot. The winding preventing device comprises a plurality of passive rotation assemblies, and simultaneously a cable with certain length is required. The plurality of assemblies can be stacked according to requirements and usually are not fewer than 3. Compared with the winding preventing technical scheme in the prior art, the winding preventing device achieves visualization, can know the condition of joint rotation by observing a deformation condition of the cable, reduces a bending degree of the cable, enables bending of the cable to be within a controllable range, and bending of each section of cable does not exceed 180 degrees.

Description

technical field [0001] The invention designs a cable routing device for a robot, in particular a wire winding prevention device for a rotary joint of a robot. Background technique [0002] The movement of the robot's active joints is generally completed by motors, drives, encoders and other equipment. These devices all need several cables such as power lines and signal lines. These cables are generally composed of multiple wires with a shield and a thick sheath, resulting in a stiff cable that is not easy to bend. [0003] A common movement mode of robot joints is rotational movement. When the movement joints rotate, the related cables will also rotate. If the required rotation angle is large, and there is no suitable method to limit or guide the cable bundles, then It will cause the cable to be entangled and pulled, which will affect the normal rotation of the joint. In severe cases, it may cause the disconnection of the welding point of the wire and the breakage of the w...
