Description

Technical Field

[0001] The utility model relates to the technical field of robot harness storage devices, in particular to a robot harness retracting device and a robot. Background Art

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. Robots can perform tasks such as operations or movements through programming and automatic control. At present, a large number of manufacturing plants have begun to use robots to replace manual labor. In order to adapt to various scenarios, the styles of robots have also become diversified, and the volume requirements of handling and humanoid robots have also tended to be miniaturized. Due to the complexity of the internal wiring harness of the robot, in order to prevent the wiring harness from being too long and interfering with the robot's movements, existing robots usually have a drag chain mechanism to store some wiring harnesses that perform motion links. The defects and shortcomings of the traditional drag chain mechanism are: it is large in size, occupies a lot of internal space of the robot, and affects the overall volume of the robot.

[0003] Therefore, there is an urgent need to provide a robot wire harness retracting device and a robot with small size and simple structure. Utility Model Content

[0027] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 1 The orientation is used as a reference.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The present embodiment provides a robot harness retracting device, including a housing 1, a sliding retracting block 2, an elastic component 3, a harness 6, at least one first harness guide wheel 4 and at least one second harness guide wheel 5.

[0030] The elastic component 3 is arranged inside the housing 1 and connected to the sliding retracting block 2. The elastic component 3 and the sliding retracting block 2 are arranged as follows: when the external force applied to the two ends of the wiring harness 6 is greater than the elastic force of the elastic component 3, the sliding retracting block 2 moves toward the direction close to the second wiring harness guide wheel 5; when the external force applied to the two ends of the wiring harness 6 is less than the elastic force of the elastic component 3, the elastic component 3 drives the sliding retracting block 2 to reset.

[0031] The working process of the robot harness retracting device of this embodiment is as follows: when the tension on both ends of the harness 6 is greater than the elastic force of the elastic component 3 on the harness retracting block 2, the harness retracting block 2 slides to the left side of the housing 1, and the two ends of the harness 6 extend outward from the housing 1, realizing the extension function (such as Figure 2 When the tension on both ends of the harness 6 is less than the elastic force of the elastic component 3 on the harness shrinking block 2, the elastic component 3 drives the harness shrinking block 2 to slide to the right side of the housing 1, and the two ends of the harness 6 shrink toward the inside of the housing 1, realizing the shrinking function (as shown in FIG. Figure 3 shown).

[0032] Furthermore, the front and rear side walls of the housing 1 are respectively provided with a limit sliding groove extending in the left and right directions to accommodate the front and rear ends of the sliding shrink block 2. The limit sliding groove is used to limit the sliding shrink block 2 to only slide horizontally.

[0033] Furthermore, the elastic component 3 is preferably a tension spring.

[0034] In this embodiment, the number of the first wire harness guide wheel 4 and the second wire harness guide wheel 5 is more than two. In practice, the number of the first wire harness guide wheel 4 and the second wire harness guide wheel 5 can be adjusted according to the usage scenario to meet the usage requirements of different telescopic lengths of the wire harness 6.

[0035] Further, along a direction perpendicular to the moving direction of the sliding retracting block 2 (ie, the front-rear direction), a plurality of first wire harness guide wheels 4 are arranged on the same straight line, and a plurality of second wire harness guide wheels 5 are arranged on the same straight line.

[0036] Furthermore, the first wire harness guide wheel 4 is rotatably connected to the sliding retracting block 2 via a fixed pin 7, the second wire harness guide wheel 5 is rotatably connected to the housing 1 via a fixed pin 7, and the axial direction of the fixed pin 7 is perpendicular to the horizontal plane.

[0037] Further, the circumferential surfaces of the first harness guide wheel 4 and the second harness guide wheel 5 are provided with grooves for accommodating the harness 6. The function of the grooves is to accommodate the harness 6 and prevent the harness 6 from falling off the first harness guide wheel 4 or the second harness guide wheel 5.

[0038] Furthermore, an installation window is provided on the upper part of the housing 1, and a cover plate (not shown in the figure) is provided at the installation window. The purpose of providing the installation window is to facilitate the installation of the sliding shrink block 2, the elastic component 3 and the wiring harness 6 inside the housing 1. After the sliding shrink block 2, the elastic component 3 and the wiring harness 6 are installed, the cover plate is placed on the installation window.

[0039] In this embodiment, the length of the housing 1 is 180 mm-240 mm, the width is 90 mm-120 mm, and the height is 20 mm-40 mm;

[0040] The diameter of the wire harness 6 is 2 mm-14 mm, the diameters of the first wire harness guide wheel 4 and the second wire harness guide wheel 5 are 10-25 mm, and the spacing between adjacent first wire harness guide wheels 4 and the spacing between adjacent second wire harness guide wheels 5 are 25-55 mm.
