Description

Technical Field

[0001] The utility model relates to the field of robots, in particular to a robot load module based on wireless energy transmission and wireless communication. Background Art

[0002] Robots are often used to replace human operations, so robots focus on sustainable use. The wires between the joints of the robot are the key to controlling the robot's operation. However, the wires passing between the two joints of the robot are easily bent due to the rotation of the joints, thus affecting the service life of the robot.

[0003] In this regard, Chinese Patent No. 202220244520.7 discloses a storage device for robot joint wires, which is located between a first actuator and a second actuator. The first actuator is used to control the rotation of the second actuator. It includes a first shell and a second shell. The first shell is connected to the output end of the first actuator, and the second shell is connected to the input end of the second actuator. A cavity structure is formed between the first shell and the second shell, and the cavity structure is used to store the joint wires. The storage device reduces the wear of the joint wires during movement by setting the joint wires connecting the first actuator and the second actuator as a spiral multi-turn tubular structure and storing them in the cavity structure, thereby improving the working stability and reliability of the robot.

[0004] However, when using the storage device provided by this patent, if the second actuator continues to rotate relative to the first actuator, the joint wire may be affected by its own length, causing pulling and bending of the joint wire, which will affect the service life of the joint wire and may cause the joint wire connection to loosen, resulting in unstable communication and energy transmission, affecting the normal use of the robot. Utility Model Content

[0005] In response to the above-mentioned problems, the robot load module based on wireless energy transmission and wireless communication provided by the utility model can solve the problem that the joint wires are easily affected by their own length when used in the prior art, causing pulling and bending of the joint wires, which affects the service life of the joint wires. It further reduces the looseness of the joint wire connections and avoids the occurrence of unstable communication and energy transmission.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model provides a robot load module based on wireless energy transmission and wireless communication, comprising a first joint, a second joint and a wireless transmission component; a rotating shaft is arranged between the first joint and the second joint; one end of the rotating shaft is rotatably fixed to the first joint, and the other end is fixed to the second joint;

[0008] The wireless transmission component includes a transmitting part and a receiving part; the transmitting part is arranged at the first joint; the receiving part is arranged at the second joint; the transmitting part and the receiving part can wirelessly transmit energy and wireless communication;

[0009] The first joint is provided with a first energy source; the first energy source is electrically connected to the transmitting part;

[0010] The second joint is also provided with an action component for energy consumption work; the action component is electrically connected to the receiving part;

[0011] The second joint is provided with a second energy source; the second energy source can be selectively electrically connected to the receiving part.

[0012] The robot load module based on wireless energy transmission and wireless communication provided by the utility model preferably uses the adjacent part of the first joint and the second joint as the end of the first joint and the front end of the second joint; the transmitting part is arranged at the end of the first joint; and the receiving part is arranged at the front end of the second joint.

[0013] The robot load module based on wireless energy transmission and wireless communication provided by the utility model is preferably such that the axis of the transmitting part coincides with the axis of the receiving part; and the axis of the transmitting part coincides with the axis of the rotating shaft.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] The robot load module based on wireless energy transmission and wireless communication provided by the utility model includes a first joint and a second joint. There is a rotation axis between the first joint and the second joint, which can be used for the relative rotation movement between the first joint and the second joint of the robot; if the method of directly connecting the first joint and the second joint through a wire is adopted to supply energy to the second joint and transmit signals, then when the first joint and the second joint rotate relative to each other, because one end of the wire is at the first joint and the other end is at the second joint, the two ends of the wire are stretched and point-to-point. At this time, the first joint and the second joint produce relative rotation, and the wire is easily wound around the rotation axis between the first joint and the second joint. Although the wire is designed with redundant length, the wire is of fixed length, and the problem of the wire being wound, bent and worn cannot be solved. Although the prior art proposes a storage device for robot joint wires, by setting the joint wires as a spiral multi-turn tubular structure and storing them in a cavity structure, it only extends the retractable length of the wires in the cavity structure, and does not actually solve the problem of wire wear and breakage caused by wire entanglement; now a wireless transmission component is adopted, including a transmitting part and a receiving part, and wireless energy transmission and wireless communication are performed between the transmitting part and the receiving part, and the wires between the transmitting part and the receiving part are removed to avoid the situation where the first joint and the second joint will be entangled when they rotate relative to each other, thereby solving the problem of wire entanglement causing pulling and bending of the wires and affecting the service life of the wires, and further reducing the looseness of the joint wire connections to avoid the occurrence of unstable communication and energy transmission.

[0016] The utility model provides a robot load module based on wireless energy transmission and wireless communication, and a second energy source is arranged on the second joint, and the second energy source can be selectively electrically connected to the receiving part; since the wireless energy transmission is subject to power limitations, the energy it transmits will not be very large. When the power of the wireless energy transmission is insufficient, it is necessary to set a second energy source connected to the receiving part. The second energy source can provide energy for the receiving part and amplify the signal, so as to avoid the situation where the first energy source cannot supply the required energy through the wireless transmission component when the receiving part needs to consume a large amount of energy, and it can ensure that while the energy is transmitted, the communication capability is improved, the loss of the control signal is avoided, and the controllability of the robot is improved.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0021] Embodiment 1:

[0022] like Figures 1-2 As shown, a robot load module based on wireless energy transmission and wireless communication provided by Example 1 of the utility model includes a first joint 1, a second joint 2 and a wireless transmission component 3; a rotating shaft 4 is arranged between the first joint 1 and the second joint 2; one end of the rotating shaft 4 is rotatably fixed to the first joint 1, and the other end is fixed to the second joint 2;

[0023] The wireless transmission component 3 includes a transmitting part 31 and a receiving part 32; the transmitting part 31 is arranged at the first joint 1; the receiving part 32 is arranged at the second joint 2; the transmitting part 31 and the receiving part 32 can wirelessly transmit energy and wireless communication;

[0024] The first joint 1 is provided with a first energy source 11; the first energy source 11 is electrically connected to the transmitting unit 31;

[0025] The second joint 2 is also provided with an action component 21 for energy consumption work; the action component 21 is electrically connected to the receiving part 32;

[0026] The second joint 2 is provided with a second energy source 22 ; the second energy source 22 can be selectively electrically connected to the receiving part 32 .

[0027] When using the robot load module based on wireless energy transmission and wireless communication provided in Example 1 of the utility model, the second joint 2 needs to make a rotational movement relative to the first joint 1. At this time, the rotating shaft 4 can rotate inside the first joint 1, and the second joint 2 fixed to the rotating shaft 4 can rotate with the rotating shaft 4; at the same time, the transmitting part 31 in the wireless transmission component 3 obtains electric energy and control information through the first energy source 11, and the transmitting part 31 transmits the electric energy and control information to the receiving part 32 in a wireless manner, the receiving part 32 obtains electric energy and control information, and supplies electric energy to the acting part 21, and the acting part 21 works according to the control information transmitted by the receiving part 32; when the power provided by the wireless transmission component 3 is insufficient, the second energy source 22 is connected to the receiving part 32, and the second energy source 22 provides energy to the receiving part 32 and amplifies the communication signal.

[0028] The robot load module based on wireless energy transmission and wireless communication provided in Example 1 of the utility model includes a first joint 1 and a second joint 2. There is a rotating shaft 4 between the first joint 1 and the second joint 2, which can be used for the relative rotation movement between the first joint 1 and the second joint 2 of the robot; if the method of directly connecting the first joint 1 and the second joint 2 through a wire is adopted to supply energy to the second joint 2 and transmit signals, then when the first joint 1 and the second joint 2 rotate relative to each other, because one end of the wire is at the first joint 1 and the other end is at the second joint 2, the two ends of the wire are stretched and point-to-point. At this time, the first joint 1 and the second joint 2 produce relative rotation, and the wire is easily entangled on the rotating shaft 4 between the first joint 1 and the second joint 2. Although the wire is designed with redundant length, the wire is fixed in length, and the problem of the wire being entangled and bent cannot be solved. In order to solve the problem of wire wear and tear, the prior art proposes a storage device for robot joint wires, which sets the joint wires as a spiral multi-turn tubular structure and stores them in a cavity structure. However, it only extends the retractable length of the wires in the cavity structure, and does not actually solve the problem of wire wear and tear caused by wire entanglement. A wireless transmission component 3 is now adopted, including a transmitting part 31 and a receiving part 32. Wireless energy transmission and wireless communication are performed between the transmitting part 31 and the receiving part 32. The wires between the transmitting part 31 and the receiving part 32 are removed to avoid the situation where the first joint 1 and the second joint 2 will be entangled when they rotate relative to each other, thereby solving the problem that the wire entanglement causes pulling and bending of the wires, affecting the service life of the wires, and further reducing the looseness of the joint wire connections to avoid the occurrence of unstable communication and energy transmission.

[0029] The robot load module based on wireless energy transmission and wireless communication provided in Example 1 of the utility model has a first joint 1 and a rotating shaft 4 that can be rotatably fixed, and a servo motor can be arranged in the first joint 1 to control the rotation of the rotating shaft 4; a wireless energy transmission device is arranged in the wireless transmission component 3 to realize the function of wireless energy transmission, and the wireless energy transmission device can be wireless energy transmission through inductive coupling; a wireless communication device is arranged in the wireless transmission component 3 to realize the function of wireless communication, and the wireless communication device can be wireless communication through WIFI or Bluetooth; the first energy source 11 can be connected to the transmitting part 31 by wire or wirelessly The first energy source 11 provides energy and control information to the transmitting part 31. When the first energy source 11 and the transmitting part 31 are connected by wire, the first energy source 11 can transmit energy and control information more stably; the transmitting part 31 wirelessly transmits the energy and control information to the receiving part 32, and the receiving part 32 is connected to the action part 21. The receiving part 32 transmits the energy and control information to the action part 21 to support and control the operation of the action part 21 on the second joint 2. The action part 21 can be an energy-consuming device such as a motor, an encoder or a PCB board. The action part 21 is used to execute or support the activities of the robot.

[0030] The robot load module based on wireless energy transmission and wireless communication provided in Example 1 of the utility model is provided with a second energy source 22 on the second joint 2, and the second energy source 22 can be selectively electrically connected to the receiving part 32; since the wireless energy transmission is limited by power, the energy it transmits will not be very large. When the power of the wireless energy transmission is insufficient, it is necessary to set the second energy source 22 to be connected to the receiving part 32. The second energy source 22 can provide energy for the receiving part 32 and amplify the signal to avoid the situation where the first energy source 11 is unable to supply the required energy through the wireless transmission component 3 when the receiving part 32 needs to consume a lot of energy, and can ensure that while the energy is transmitted, the communication capability is improved, the control signal loss is avoided, and the controllability of the robot is improved.

[0031] The robot load module based on wireless energy transmission and wireless communication provided in Example 1 of the utility model preferably takes the adjacent part of the first joint 1 and the second joint 2 as the end of the first joint 1 and the front end of the second joint 2, the transmitting part 31 is arranged at the end of the first joint 1, and the receiving part 32 is arranged at the front end of the second joint 2. The transmitting part 31 and the receiving part 32 are kept at a distance of the length of a rotating axis 4. The constant distance is conducive to maintaining the normal working efficiency of the wireless energy transmission device. At the same time, when the transmitting part 31 and the receiving part 32 are arranged at the nearest part of the first joint 1 and the second joint 2, the adjacent transmitting part 31 and the receiving part 32 have stronger energy transmission efficiency and communication efficiency, reduce the energy loss in wireless energy transmission, and improve the clarity of communication.

[0032] The robot load module based on wireless energy transmission and wireless communication provided in Example 1 of the utility model preferably, when the wireless energy transmission device chooses to adopt the inductive coupling method for wireless energy transmission, it is necessary to set inductors in the transmitting part 31 and the receiving part 32. If the first joint 1 and the second joint 2 rotate relative to each other, and the center of the transmitting part 31 and the center of the receiving part 32 are not in the same straight line, the working efficiency between the inductors will be reduced, so that the efficiency of wireless energy transmission and wireless communication will be reduced. In order to further improve the quality of wireless energy transmission and wireless communication, the axis of the transmitting part 31 is coincident with the axis of the receiving part 32, and the axis of the transmitting part 31 is coincident with the axis of the rotating shaft 4. At this time, the inductors in the transmitting part 31 and the receiving part 32 can maintain good electromagnetic induction, thereby improving the stability of communication and energy transmission.

[0033] To sum up, the robot load module based on wireless energy transmission and wireless communication provided by the utility model can solve the problem that the joint wires are easily affected by their own length when used in the prior art, causing pulling and bending of the joint wires, which affects the service life of the joint wires. It further reduces the looseness of the joint wire connections and avoids the occurrence of unstable communication and energy transmission.
