Description

Technical Field

[0001] This utility model relates to the field of robotic arms, and more particularly to a robotic arm with an electrical connection wire. Background Technology

[0002] Robotic arms are a core component of the field of robotics. Essentially, they are programmable, humanoid arm-like mechanical devices that achieve the movement of each joint through core components such as precision reducers, servo motors, and drivers.

[0003] In related technologies, when a robotic arm is in use, it needs to be connected to different parts of the robotic arm via wires. Typically, the wires are brought in from the outside and then wound around the outer perimeter of the robotic arm to make electrical connections between the various parts of the robotic arm.

[0004] Regarding the aforementioned technologies, the inventors believe that when the robotic arm is working, the wires wrapped around the outer perimeter of the robotic arm may become entangled with the robotic arm itself or interfere with the outside environment, thereby affecting the normal operation of the robotic arm. Utility Model Content

[0005] To address the problem of wires from robotic arms becoming entangled with the robotic arm body or interfering with external factors, this invention provides a robotic arm with an electrical connection wire.

[0006] The present invention provides a robotic arm with an electrical connection wire, which adopts the following technical solution: A robotic arm with an electrical connection cable includes a connector for connecting to a robot and a robotic arm connected to the connector and having electrical wires. The robotic arm includes a first connecting cylinder, a second connecting cylinder, and a connector. The connector has an access hole for the power supply cable. The robotic arm has a circuit board inside for the power supply cable to connect the first connecting cylinder, the second connecting cylinder, and the connector.

[0007] By adopting the above technical solution, external wires are connected to the robotic arm through access holes, and the wires are connected inside the robotic arm through an internal circuit board, thereby reducing the situation where wires are wrapped around the outside of the robotic arm and cause them to become entangled with the robotic arm.

[0008] Optionally, each of the connectors is provided with a connecting piece for connecting and fixing the connecting seat, the first connecting cylinder and the second connecting cylinder, and each of the connectors and the connecting piece is provided with an output hole for power supply output.

[0009] By adopting the above technical solution, the first connecting cylinder and the second connecting cylinder of the robotic arm are connected by a connector, and the first connecting cylinder and the second connecting cylinder can be connected by an output hole, making the disassembly and installation of the robotic arm more convenient.

[0010] Optionally, the robotic arm further includes a rotating component fixed on the connecting plate, the rotating component having a terminal block for power supply connection, and the rotating component having a communication port communicating with the first connecting cylinder or the second connecting cylinder.

[0011] By adopting the above technical solution, the robotic arm can achieve relative rotation between its various parts through rotating components, enabling the robotic arm to perform complex movements with multiple degrees of freedom. Furthermore, the wiring can be connected through the terminal block, ensuring the electrical signal connection between the various parts of the robotic arm.

[0012] Optionally, the rotating part on the first connecting cylinder is provided with a cable routing sleeve for the power supply line, and a cavity for the power supply line to move is opened inside the cable routing sleeve. A cable routing hole for the power supply line to pass through is opened on the side wall of the first connecting cylinder, and the power supply line is arranged in a U-shape inside the cavity.

[0013] By adopting the above technical solution, the wires inside the cavity are protected by the wiring sleeve, so that they will not be exposed outside the robotic arm and interfere with other parts. In addition, the U-shaped arrangement of the wires allows the wires to extend and retract automatically when the robotic arm rotates, so that the wires will not get tangled inside the cavity.

[0014] Optionally, a wear-resistant sleeve is provided on the wire inside the cavity.

[0015] By adopting the above technical solutions, the wear-resistant sleeve can protect the wires inside the cavity, reduce direct contact and dynamic friction between the wires and the surrounding structure, and resist fatigue damage caused by vibration, impact and periodic bending, thus extending the service life of the wires.

[0016] Optionally, the wear-resistant sleeve includes an elastic net, a pull tab, and a pull rope. The elastic net is fitted onto the pull tab and rolled towards the center. The pull tab drives the pull rope to pull the elastic net open so that the elastic net is fitted onto the wire.

[0017] By adopting the above technical solution, the elastic net can be put on the wire to protect it by pulling the tab, which simplifies the operation in a limited space and allows the elastic net to protect the wire even in a small cavity after installation.

[0018] Optionally, the rotating part on the second connecting cylinder is also provided with a connecting sleeve. Both the second connecting cylinder and the connecting sleeve of the rotating part on the second connecting cylinder are provided with connecting blocks to guide the direction of the wires. A protective sleeve for the power supply wires to pass through is provided between the connecting blocks.

[0019] By adopting the above technical solution, when the wire is routed on the second connecting tube, the direction of the wire can be guided by the connecting block, and the protective sleeve can protect the wire and reduce wear and tear on the surrounding structure during routing, thus extending the service life of the wire.

[0020] Optionally, the protective sleeve is wound around the outer side wall of the second connecting cylinder in a circumferential direction.

[0021] By adopting the above technical solution, the protective sleeve can not only protect the wires but also guide their direction, allowing the wires to run along the circumferential direction of the outer wall of the second connecting cylinder. This prevents the wires from interfering with surrounding components during the wiring process and reduces cable damage caused by arbitrary bending or tangling.

[0022] Optionally, both ends of the protective sleeve are provided with rubber plugs through which the power supply line is inserted for connecting blocks.

[0023] By adopting the above technical solution, the rubber plug, through its elastic material, fits tightly with the connecting block, which can effectively fix and protect the wire inlet and outlet ends, preventing them from loosening when vibrating or under stress. In addition, the rubber material has good sealing properties, which can prevent dust, moisture and foreign objects from entering the protective sleeve under complex working conditions.

[0024] Optionally, the rubber plug is provided with a protrusion in the circumferential direction that presses against the connecting block.

[0025] By adopting the above technical solution, the interference fit formed between the protrusion and the connecting block can generate a continuous radial extrusion force, thereby ensuring that the rubber plug can be firmly embedded and held in the predetermined position. This facilitates the sliding of the flexible protrusion into the connecting block during installation and allows for self-locking through elastic deformation after positioning, thus balancing assembly efficiency and connection reliability.

[0026] In summary, this utility model has at least one of the following beneficial technical effects: By connecting the external wires to the robotic arm via a circuit board and routing the wires inside the robotic arm, wear and tear on the wires is reduced. The wires are arranged in a U-shape inside the cavity. When the robotic arm rotates, the wires can extend and retract accordingly to prevent them from interfering with the operation of the robotic arm. The wires are routed along the outer circumferential direction of the second connecting cylinder along the protective sleeve to prevent interference with surrounding components during the routing process.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] This utility model discloses a robotic arm with an electrical connection wire.

[0031] Reference Figure 1 A robotic arm with an electrical connection cable includes a robotic arm 1, a connecting base 2, and an electrical wire 3. The robotic arm 1 is connected to the robot body via the connecting base 2. The robotic arm 1 has an access hole 141 for the power supply cable 3, allowing the external electrical wire 3 to connect to the robotic arm 1.

[0032] Reference Figure 1 The robotic arm 1 includes a first connecting cylinder 11, a second connecting cylinder 12, a connecting plate 13, a connecting member 14, and a rotating member 15. The connecting member 14 is threadedly connected to one end of the connecting seat 2, the first connecting cylinder 11, and the second connecting cylinder 12. The connecting plate 13 is rotatably connected to the connecting member 14, and the rotating member 15 is threadedly connected to the connecting plate 13. When the robotic arm 1 is working, the connecting seat 2, the first connecting cylinder 11, and the second connecting cylinder 12 rotate relative to each other on the connecting plate 13 via the rotating member 15, thereby achieving relative rotation between the various parts of the robotic arm 1 to complete the work of the robotic arm 1.

[0033] Reference Figure 1An access hole 141 is opened on the connector 14 connected to the connector 2. The connector 13 has an output hole 131, and the rotating part 15 has a terminal block 151. The wire 3 is connected to the robotic arm 1 through the access hole 141 and outputs through the output hole 131 to the terminal block 151, thereby electrically connecting different parts of the robotic arm 1, including the connector 2, the first connecting cylinder 11, the second connecting cylinder 12, the connector 14, and the rotating part 15, so that the robotic arm 1 can work normally.

[0034] Reference Figure 2 and Figure 3 The robotic arm 1 has a circuit board 16 soldered inside. A connecting port 152 is opened on the rotating component 15, and a wiring sleeve 153 for the power supply wire 3 is soldered onto the rotating component 15. The wiring sleeve 153 has a cavity 1531 inside. A wiring hole 111 is located on the side wall of the first connecting cylinder 11, and the wire 3 is arranged in a U-shape within the cavity 1531. The circuit board 16 connects the wire 3 inside the robotic arm 1, and the connecting port 152 routes the wire 3 into the cavity 1531 of the wiring sleeve 153, preventing interference between the wire 3 and external parts. Furthermore, the U-shaped arrangement of the wire 3 allows it to retract automatically as the robotic arm 1 rotates, preventing it from interfering with the normal operation of the robotic arm 1. The wire 3 continues to run inside the robotic arm 1 through the wiring hole 111.

[0035] Reference Figure 4 and Figure 5 The wire 3 inside the cavity 1531 is fitted with a wear-resistant sleeve 31, which includes an elastic mesh 311, a pull tab 312, and a pull rope 313. When the wire 3 is not installed in the cavity 1531, the wear-resistant sleeve 31 can be fitted onto the wire 3. When the wire 3 is used in the cavity 1531, the pull tab 312 can be pulled to drive the pull rope 313, thereby causing the elastic mesh 311 to open and fit over the wire 3, thus protecting the wire 3, reducing direct contact and dynamic friction between the wire 3 and the surrounding structure, and extending the service life of the wire 3.

[0036] Reference Figure 6 and Figure 7 A connecting sleeve 154 is welded to the rotating part 15 of the second connecting cylinder 12. A connecting block 121 is welded to the connecting sleeve 154 to guide the direction of the wire 3. A protective sleeve 122 is provided between the connecting blocks 121 to allow the power supply wire to pass through. The wire 3 on the second connecting cylinder 12 can be routed around the circumference of the outer wall of the second connecting cylinder 12 under the guidance of the connecting block 121, and is isolated from external parts under the protection of the protective sleeve 122 to avoid interference with external parts.

[0037] refer to Figure 6 and Figure 7A rubber stopper 1221 is glued to the protective sleeve 122, and a protrusion 12211 is glued to the rubber stopper 1221. When the protective sleeve 122 is installed into the connecting block 121, the cooperation between the rubber stopper 1221 and the protrusion 12211 makes the structure of the protective sleeve 122 more secure. After the protective sleeve 122 is installed into the connecting block 121, the rebound action of the protrusion 12211 makes the protective sleeve 122 less likely to loosen and detach.

[0038] The implementation principle of a robotic arm with an electrical connection wire in this embodiment of the present invention is as follows: the robotic arm 1 connects the wire 3 to the robotic arm 1 through the access hole 141, and integrates the wire 3 through the circuit board 16 inside the robotic arm 1 and connects them inside the robotic arm 1. The robotic arm 1 can achieve normal operation through the relative rotation between the connecting member 14 and the rotating member 15.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
