Abstract
Description
Technical Field
[0001] This utility model relates to the field of robots, and in particular to a robot cable guiding device. Background Technology
[0002] With the continuous development of production automation, robots are playing an increasingly important role in production. Monotonous and tedious tasks can be completed by robots, which not only saves manpower but also increases work efficiency.
[0003] When the robot's arm moves, it is connected to many cables that control the movement of the robot's arm. These cables are used to achieve the movement of the robot arm.
[0004] Existing robots typically use cable packages to install cables onto the robot. As the robot's arm extends away from itself, the cable also extends in that direction. When the robot's arm retracts towards itself, the cable may bend, become entangled with other cables, and be damaged, causing the robot's arm to malfunction and thus affecting the work process. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides a robot cable guiding device.
[0006] The robot cable guiding device provided in this application adopts the following technical solution:
[0007] A robot cable guiding device, comprising: The housing has a hollow interior and both ends are open. The walls of the openings at both ends of the housing are recessed towards the central axis of the housing to form limiting shoulders. A corrugated pipe, wherein the corrugated pipe is located inside the housing and both ends of the corrugated pipe extend outside the housing, and the cable is wrapped inside the corrugated pipe; A limiting member, which is annular and fixedly connected to the bellows, is located between two limiting shoulders, and the maximum outer diameter of the limiting member is greater than the minimum inner diameter of the limiting shoulders. A spring, which is sleeved on a bellows and located between two limiting shoulders, with one end of the spring abutting against a limiting member and the other end of the spring abutting against a limiting shoulder; A fastener is attached to the limiting shoulder.
[0008] Preferably, the housing includes a unit housing 1 and a unit housing 2 that can be assembled. The unit housing 1 is provided with connecting ear plates 1 on both radial sides, and the unit housing 2 is provided with connecting ear plates 2 on both radial sides. The connecting ear plates 2 correspond to the connecting ear plates 1, and the connecting ear plates 2 and the corresponding connecting ear plates 1 are fixed by screws.
[0009] Preferably, the cross-section of the fastener is a regular polygon, and the cross-section of the housing is also a regular polygon, with the plane of the housing corresponding one-to-one with the plane of the fastener; The fastener includes a first body and a second body that are rotatably connected. One radial end of the first body and the second body are hinged together, and the other radial end of the first body and the second body are connected by a bolt pair.
[0010] Preferably, the fastener has mounting holes on its flat surface for connection with the robot's arm.
[0011] Preferably, multiple mounting holes are spaced apart along the length of the corresponding plane.
[0012] Preferably, the fastener has mounting holes on both opposite planes.
[0013] Preferably, the fasteners have mounting holes on two opposite planes. When the upper and lower fasteners are stacked, the mounting holes of the upper and lower fasteners are connected when the bottom surface of the upper fastener abuts against the top surface of the lower fastener.
[0014] In summary, this application includes the following beneficial technical effects: During the cable extension process, the cable and corrugated tube are stretched to the right together, and the limiting component moves to the right along with the corrugated tube. The spring is compressed by the limiting component and the limiting shoulder. When the cable and corrugated tube retract to the left, the spring extends, the limiting component resets to the left, and the corrugated tube and cable are synchronously and smoothly reset, providing guidance for the movement of the cable, thereby reducing the possibility of the cable bending or getting tangled with other cables and being damaged, reducing cable damage, and enabling the robot arm to maintain normal operation. When the limiting member is limited by the limiting shoulder on the left, it can prevent the limiting member and the spring from detaching from the housing. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0020] This application discloses a robot cable guiding device.
[0021] Reference Figure 1-3 The robot cable guide device includes a housing 1, which is hollow inside. Both ends of the housing 1 are open, and the walls of the openings at both ends of the housing 1 are recessed toward the central axis of the housing 1 to form a limiting shoulder 2.
[0022] A bellows 3 is installed inside the housing 1. The bellows 3 is located inside the housing 1 and both ends of the bellows 3 extend out of the housing 1. The cable is wrapped inside the bellows 3. The bellows 3 and the cable slide together under the action of friction.
[0023] A limiting element 4 is provided on the corrugated pipe 3. The limiting element 4 is annular and fixedly connected to the corrugated pipe 3. The limiting element 4 is located between two limiting shoulders 2. The maximum outer diameter of the limiting element 4 is greater than the minimum inner diameter of the limiting shoulders 2.
[0024] A spring 5 is fitted onto the bellows 3 and is located inside the housing 1. The spring 5 is positioned between two limiting shoulders 2, with one end of the spring 5 abutting against the limiting member 4 and the other end abutting against the limiting shoulder 2. When the limiting member 4 is limited by the left limiting shoulder 2, the limiting member 4 and the spring 5 are prevented from detaching from the housing 1.
[0025] During the cable extension process, the cable and corrugated tube 3 are stretched to the right together, and the limiting member 4 moves to the right together on the corrugated tube 3. The spring 5 is compressed by the limiting member 4 and the limiting shoulder 2. When the cable and corrugated tube 3 retract to the left, the spring 5 extends, and the limiting member 4 resets to the left, bringing the corrugated tube 3 and cable back to their original straight position in sync. This provides guidance for the movement of the cable, thereby reducing the possibility of the cable bending or getting tangled with other cables and thus reducing cable damage, allowing the robot arm to maintain normal operation. When the limiting member 4 is limited by the limiting shoulder 2 on the left, the limiting member 4 and the spring 5 are prevented from detaching from the housing 1.
[0026] The housing 1 includes two modular housing units, 1-a and 1-b, which can be assembled. Connecting lugs 111 are provided on both radial sides of unit housing 1-a, and connecting lugs 121 are provided on both radial sides of unit housing 1-b. Connecting lugs 121 correspond to connecting lugs 111 and are fixed to their corresponding connecting lugs 111 by screws. The modular design of the housing 1 facilitates the assembly of cables, corrugated pipes 3, springs 5, and limiting components 4.
[0027] Each end of the housing 1 is provided with a fixing member 6. The cross-section of the fixing member 6 is a regular polygon, and the cross-section of the housing 1 is also a regular polygon. The plane of the housing 1 corresponds one-to-one with the plane of the fixing member 6. The fixing member 6 is engaged at the limiting shoulder 2. The fixing member 6 includes a first body 61 and a second body 62 that are rotatably connected. One radial end of the first body 61 and the second body 62 is hinged, and the other radial end of the first body 61 and the second body 62 is connected by a bolt pair.
[0028] The fastener 6 has a mounting hole 63 on its flat surface for connecting with the robot arm. The housing 1 can be mounted on the robot arm through the flat surface of the fastener 6 and the mounting hole 63.
[0029] Multiple mounting holes 63 are spaced apart along the length of the corresponding plane to facilitate adjustment of the installation position as needed.
[0030] The two opposite planes of the fastener 6 have mounting holes 63. The upper and lower fasteners 6 can be stacked. When the bottom surface of the upper fastener 6 abuts against the top surface of the lower fastener 6, the mounting holes 63 of the upper and lower fasteners 6 are connected, so that the housing 1 can be stacked vertically, which is convenient for guiding and directing multiple cables.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
