Description

Technical Field

[0001] The utility model relates to the technical field of robot equipment, in particular to a mechanical arm and a robot. Background Art

[0002] With the development of robotics technology, the application of six-axis robots is becoming more and more widespread, and the requirements for the range of motion and speed of each joint are becoming increasingly higher. In particular, small six-axis robots require both a lightweight body and a large load capacity, while also requiring extremely high joint speed and response.

[0003] At present, the small six-axis robots in related technologies are mostly used in the 3C electronics industry and loading and unloading of machine tools. The protection level of the robot itself is very high. Therefore, the robot's joint reducer and motor will be sealed inside the robot shell, resulting in the heat generated by the joints not being easy to dissipate. Utility Model Content

[0004] The embodiments of the present utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the present invention provides a robotic arm.

[0006] A second aspect of the embodiments of the present invention provides a robot.

[0007] In view of this, according to the first aspect of an embodiment of the present utility model, a robotic arm is provided, which includes: an arm body, the arm body is provided with a accommodating cavity; a driving assembly, arranged in the accommodating cavity and connected to the arm body; a heat sink, arranged in the accommodating cavity, the heat sink includes a plurality of heat sinks, and the plurality of heat sinks are distributed at intervals, and each heat sink is located between the driving assembly and the cavity wall of the accommodating cavity.

[0008] The robotic arm provided in an embodiment of the present invention includes an arm body, a drive assembly, and a heat sink. Specifically, the drive assembly is connected to the arm body, that is, the drive assembly is capable of driving the arm body to rotate. The drive assembly is disposed within a housing cavity, that is, sealed within the housing cavity, which helps to improve the protection level of the robotic arm and meet the needs of use in various working conditions.

[0009] It is understandable that during the operation of the robot, the drive component will generate heat. Since the drive component is sealed in the accommodating cavity, if the heat generated by the drive component cannot be dissipated in time, it will affect the service life of the drive component, increase the probability of failure, and reduce the reliability of the robot.

[0010] The heat sink is arranged in the accommodating cavity, and the heat sink includes multiple heat sinks, each of which is located between the drive assembly and the cavity wall of the accommodating cavity, so that the heat generated by the drive assembly can be quickly transferred to the outside of the arm body through the multiple heat sinks and dissipated into the air, thereby realizing heat dissipation of the robotic arm during operation.

[0011] The multiple heat sinks are spaced apart, effectively increasing the heat conduction area of ​​the heat sink. This allows the heat generated by the drive assembly to be promptly dissipated through the fins. This ensures the robot's protection level while effectively dissipating heat from the drive assembly, reducing the probability of drive assembly failure, extending its service life, and improving the robot's reliability. Furthermore, by placing a heat sink between the drive assembly and the cavity wall, rapid heat dissipation is achieved, resulting in a simple structure and easy operation.

[0012] Furthermore, compared to the related art approach of using higher-power motors to reduce motor heat generation by pulling a small cart with a large horse, this approach avoids the problem of increased weight and cost due to oversized motors. Furthermore, compared to the related art approach of reducing motor heat generation by slowing joint speed, this approach ensures robot performance and motor utilization, meeting the robot's performance, weight, and cost requirements.

[0013] In addition, the robotic arm provided by the above technical solution of the utility model also has the following additional technical features:

[0014] In some technical solutions, optionally, any two adjacent heat sinks form a heat dissipation channel, and the heat dissipation channel has an opening, and the opening faces the drive assembly.

[0015] In this technical solution, any two adjacent heat sinks are defined to form a heat dissipation channel. Specifically, the opening of the heat dissipation channel faces the drive assembly. That is, one end of each heat sink is connected to the cavity wall of the accommodating cavity, and the other end extends toward the drive assembly, thereby effectively increasing the heat dissipation area of ​​the heat sink, so that the heat generated by the drive assembly can be dissipated in time through multiple heat sinks, ensuring the protection level of the robotic arm while achieving effective heat dissipation of the drive assembly.

[0016] In some technical solutions, optionally, the number of the heat sinks is at least two, and the at least two heat sinks are respectively located on different sides of the drive assembly.

[0017] In this technical solution, the number of heat sinks is limited to at least two. Specifically, the at least two heat sinks are located on different sides of the drive assembly. Optionally, the at least two heat sinks are located on opposite sides of the drive assembly, and / or the at least two heat sinks are located on adjacent sides of the drive assembly. The specific configuration can be determined based on actual needs.

[0018] Specifically, during the operation of the robot, the heat generated by the drive assembly can be dissipated through at least two heat sinks. Since the at least two heat sinks are located on different sides of the drive assembly, the heat generated by the drive assembly can be dissipated through both sides of the drive assembly, which can significantly improve the heat dissipation effect of the drive assembly, thereby helping to improve the performance and reliability of the robot and meet the performance, weight and cost requirements of the robot.

[0019] In some technical solutions, optionally, the robotic arm further includes a heat conductor, which is located between the drive assembly and the heat sink.

[0020] In this technical solution, it is defined that the robotic arm also includes a heat conductor. Specifically, the heat conductor is located between the drive assembly and the heat sink. That is to say, the heat conductor is filled in the gap between the drive assembly and the heat sink, so that the heat generated by the drive assembly can be transferred to the outside of the arm body in a timely and rapid manner through the heat conductor and the heat sink in turn, which is conducive to improving the efficiency of heat transfer, thereby improving the heat dissipation effect of the drive assembly, meeting the heat dissipation requirements while ensuring the performance of the robot.

[0021] In some technical solutions, optionally, two sides of the heat conducting element are in contact with the driving assembly and the heat dissipating element respectively.

[0022] In this technical solution, it is defined that the two sides of the heat conductor are in contact with the driving component and the heat sink respectively. Optionally, the heat conductor includes a first side and a second side opposite to each other, wherein the first side is in contact with the driving component and the second side is in contact with the heat sink.

[0023] Since the two sides of the heat conductor are in contact with the drive assembly and the heat sink respectively, the efficiency of heat transfer can be further improved, the heat dissipation effect can be enhanced, and the heat dissipation requirements can be met. Moreover, the structure is simple. Compared with the related art that uses a larger power motor and reduces the heat generation of the motor by the method of a large horse pulling a small cart, it can avoid the problem of increased weight and cost of the whole machine due to the selection of an oversized motor. In addition, compared with the related art that reduces the heat generation of the motor by reducing the joint speed, it can ensure the performance of the robot and the utilization rate of the motor, and meet the robot's performance, weight and cost requirements.

[0024] In some technical solutions, optionally, the heat conducting element includes a plurality of heat conducting sheets, and the plurality of heat conducting sheets are stacked and arranged in a direction from the driving component to the heat dissipating element.

[0025] In this technical solution, it is defined that the heat conducting member includes a plurality of heat conducting sheets. Specifically, a plurality of heat conducting sheets are stacked and arranged along the direction from the driving component to the heat sink. That is to say, a plurality of heat conducting sheets are filled in the gap between the driving component and the heat sink, so that the heat generated by the driving component can be transferred to the outside of the arm body in a timely and rapid manner through the plurality of heat conducting sheets and the heat sink in turn, which is conducive to improving the efficiency of heat transfer, thereby improving the heat dissipation effect of the driving component, meeting the heat dissipation requirements while ensuring the performance of the robot.

[0026] It can be understood that the number of heat conducting plates can be determined according to the size of the gap between the driving component and the heat sink, so that the heat conducting plates located on both sides of the multiple heat conducting plates can respectively contact the driving component and the heat sink to improve the efficiency of heat transfer.

[0027] Optionally, the heat conductive sheet includes a heat conductive silicone sheet.

[0028] In some technical solutions, optionally, the heat sink and the arm body are an integrated structure.

[0029] This technical solution defines an integrated structure between the heat sink and the arm body. This integrated structure, as can be appreciated, offers excellent mechanical properties, thereby enhancing the connection strength between the heat sink and the arm body and ensuring effective heat dissipation from the drive assembly. Furthermore, this integrated structure facilitates the fabrication of the arm body, reducing its manufacturing complexity and, consequently, its production cost.

[0030] In addition, the arm body is generally a metal part to ensure the overall structural strength of the robotic arm. Since the heat sink and the arm body are an integrated structure, that is, the heat sink is also a metal part, it can be understood that the metal part has good thermal conductivity, which can improve the efficiency of heat transfer and further improve the heat dissipation effect of the drive component.

[0031] In some technical solutions, optionally, the driving assembly includes a motor and a reducer, wherein the heat sink is located between the cavity wall of the accommodating cavity and the motor, the reducer is connected to the motor, and the arm body is connected to the reducer.

[0032] In this technical solution, it is defined that the driving assembly includes a motor and a reducer. Specifically, the reducer is connected to the motor, and the arm body is connected to the reducer. That is, under the drive of the motor, the reducer drives the arm body to rotate.

[0033] It is understandable that during the operation of the robot, the motor generates more heat than the reducer. By setting the heat sink between the motor and the wall of the accommodating cavity, the heat generated by the motor can be quickly transferred to the outside of the arm body through the heat sink, ensuring the heat dissipation effect of the motor, meeting the heat dissipation requirements, and helping to further improve the reliability of the robot.

[0034] In some technical solutions, optionally, the arm body includes a connecting portion, the connecting portion is provided with a accommodating cavity, and the robotic arm further includes a rotating seat, which is rotatably connected to the connecting portion.

[0035] In this technical solution, it is defined that the robotic arm also includes a rotating seat. Specifically, the arm body includes a connecting portion, which is rotatably connected to the rotating seat. It can be understood that the rotating seat is rotatably connected to the fixed seat of the robot.

[0036] Since the connection part is provided with a accommodating cavity, that is, the drive assembly is located at the joint of the robotic arm, a heat sink is provided at the joint to dissipate heat from the drive assembly, so that the heat generated by the drive assembly can be dissipated in time through multiple heat sinks, ensuring the protection level of the robotic arm while achieving effective heat dissipation of the drive assembly, reducing the probability of failure of the drive assembly, extending the service life of the drive assembly, and improving the reliability of the robot.

[0037] In some technical solutions, optionally, the arm body is a metal part; and / or the heat sink is a metal part.

[0038] In this technical solution, the arm body is specifically constructed of metal, thereby ensuring the overall structural strength of the robotic arm. Furthermore, since heat generated by the drive assembly is transferred to the air via the heat sink and the arm body, dissipating heat, the metal arm body improves heat transfer efficiency, further enhancing the heat dissipation of the drive assembly.

[0039] The heat sink is a metal part, that is, each heat sink is a metal sheet. It can be understood that the metal part has good thermal conductivity, which can improve the efficiency of heat transfer and further improve the heat dissipation effect of the drive component.

[0040] According to the second aspect of the present invention, a robot is provided, comprising a robotic arm as provided by any of the above technical solutions, thereby possessing all the beneficial technical effects of the robotic arm, which will not be repeated here.

[0041] In addition, the robot provided by the above technical solution of the utility model also has the following additional technical features:

[0042] In some technical solutions, optionally, there are multiple robotic arms, and the multiple robotic arms include at least a first arm and a second arm. The robot also includes a fixed seat, and both ends of the first arm are rotatably connected to the fixed seat and the second arm respectively.

[0043] In this technical solution, the number of robotic arms is limited to multiple. Specifically, the multiple robotic arms include a first arm and a second arm. One end of the first arm is rotatably connected to the fixed seat, and the other end of the first arm is rotatably connected to the second arm. That is to say, if the fixed seat is the first joint, the first arm is the second joint, and the second arm is the third joint.

[0044] It is understandable that in most actual application conditions, the A2 and A3 axes of the robot are subjected to the most complex stress conditions, are used most frequently, and generate the most heat. Heat sinks are respectively provided in the accommodating cavities of the first arm and the second arm to dissipate heat from the drive components. That is, heat sinks are provided in the parts of the robot that generate more heat for heat dissipation, thereby achieving effective heat dissipation during the robot's operation, meeting the heat dissipation requirements, and helping to reduce the production cost of the robot.

[0045] Additional aspects and advantages of the present invention will be given in the following description, and some will become obvious from the following description, or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0058] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0059] Refer to the following Figures 1 to 8 To describe the robotic arm 100 and the robot provided according to some embodiments of the present invention.

[0060] In one embodiment according to the present application, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, a robotic arm 100 is proposed, which includes: an arm body 110, which is provided with a accommodating cavity 111; a driving component 120, which is arranged in the accommodating cavity 111 and connected to the arm body 110; a heat sink 130, which is arranged in the accommodating cavity 111, and includes a plurality of heat sinks 131, which are distributed at intervals, and each heat sink 131 is located between the driving component 120 and the cavity wall of the accommodating cavity 111.

[0061] The robotic arm 100 provided in the embodiment of the present invention includes an arm body 110, a drive assembly 120, and a heat sink 130. Specifically, the drive assembly 120 is connected to the arm body 110, that is, the drive assembly 120 can drive the arm body 110 to rotate. The drive assembly 120 is disposed in an accommodating cavity 111. In other words, the drive assembly 120 is sealed in the accommodating cavity 111, which helps to improve the protection level of the robotic arm 100 and meet the use requirements under various working conditions.

[0062] It is understandable that during the operation of the robot, the drive component 120 will generate heat. Since the drive component 120 is sealed in the accommodating cavity 111, if the heat generated by the drive component 120 cannot be dissipated in time, it will affect the service life of the drive component 120, increase the probability of failure, and reduce the reliability of the robot.

[0063] The heat sink 130 is arranged in the accommodating cavity 111, and the heat sink 130 includes a plurality of heat sinks 131, each heat sink 131 is located between the driving component 120 and the cavity wall of the accommodating cavity 111, so that the heat generated by the driving component 120 can be quickly transferred to the outside of the arm body 110 through the plurality of heat sinks 131 and dissipated into the air, thereby realizing heat dissipation of the robotic arm 100 during operation.

[0064] Because multiple heat sinks 131 are spaced apart, the heat transfer area of ​​heat sink 130 is effectively increased, allowing heat generated by drive assembly 120 to be promptly dissipated through multiple heat sinks 131. This ensures the protection level of robotic arm 100 while effectively dissipating heat from drive assembly 120, reducing the probability of failure of drive assembly 120, extending the service life of drive assembly 120, and improving the reliability of the robot. Furthermore, by disposing heat sink 130 between drive assembly 120 and the wall of accommodating chamber 111, rapid heat dissipation is achieved, resulting in a simple structure and easy operation.

[0065] Furthermore, compared to the related art method of using a larger motor to reduce motor heat generation by pulling a small cart, this method avoids the problem of increased weight and cost due to over-sized motor 121. Furthermore, compared to the related art method of reducing motor heat generation by reducing joint speed, this method ensures robot performance and motor 121 utilization, meeting robot performance, weight, and cost requirements.

[0066] like Figure 2 and Figure 8 As shown, in some embodiments, optionally, any two adjacent heat sinks 131 form a heat dissipation channel 132 , and the heat dissipation channel 132 has an opening 133 , and the opening 133 faces the driving assembly 120 .

[0067] In this embodiment, any two adjacent heat sinks 131 are defined to form a heat dissipation channel 132. Specifically, the opening 133 of the heat dissipation channel 132 faces the drive assembly 120. That is, one end of each heat sink 131 is connected to the cavity wall of the accommodating cavity 111, and the other end extends toward the drive assembly 120, thereby effectively increasing the heat dissipation area of ​​the heat sink 130, so that the heat generated by the drive assembly 120 can be dissipated in time through multiple heat sinks 131, ensuring the protection level of the robotic arm 100 while achieving effective heat dissipation of the drive assembly 120.

[0068] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 8 As shown, in some embodiments, optionally, the number of the heat sinks 130 is at least two, and the at least two heat sinks 130 are respectively located on different sides of the driving assembly 120 .

[0069] In this embodiment, the number of heat sinks 130 is limited to at least two. Specifically, the at least two heat sinks 130 are located on different sides of the drive assembly 120. Alternatively, the at least two heat sinks 130 are located on opposite sides of the drive assembly 120, and / or the at least two heat sinks 130 are located on adjacent sides of the drive assembly 120. The specific configuration can be determined based on actual needs.

[0070] Specifically, during the operation of the robot, the heat generated by the drive component 120 can be dissipated through at least two heat sinks 130. Since the at least two heat sinks 130 are respectively located on different sides of the drive component 120, the heat generated by the drive component 120 can be dissipated through both sides of the drive component 120, which can significantly improve the heat dissipation effect of the drive component 120, thereby helping to improve the performance and reliability of the robot and meet the performance, weight and cost requirements of the robot.

[0071] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, optionally, the robotic arm 100 further includes a heat conductor 140 , which is located between the drive assembly 120 and the heat sink 130 .

[0072] In this embodiment, it is defined that the robotic arm 100 also includes a heat conductor 140. Specifically, the heat conductor 140 is located between the drive component 120 and the heat sink 130. That is, the heat conductor 140 is filled in the gap between the drive component 120 and the heat sink 130, so that the heat generated by the drive component 120 can be transferred to the outside of the arm body 110 in a timely and rapid manner through the heat conductor 140 and the heat sink 130 in turn, which is beneficial to improving the efficiency of heat transfer, thereby improving the heat dissipation effect of the drive component 120, meeting the heat dissipation requirements while ensuring the performance of the robot.

[0073] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, optionally, two sides of the heat conducting member 140 are in contact with the driving assembly 120 and the heat dissipating member 130 respectively.

[0074] In this embodiment, the two sides of the heat conductor 140 are respectively in contact with the drive assembly 120 and the heat sink 130. Optionally, the heat conductor 140 includes a first side and a second side relative to each other, wherein the first side is in contact with the drive assembly 120 and the second side is in contact with the heat sink 130.

[0075] Since the two sides of the heat conductor 140 are in contact with the drive assembly 120 and the heat sink 130 respectively, the efficiency of heat transfer can be further improved, the heat dissipation effect can be improved, and the heat dissipation requirements can be met. Moreover, the structure is simple. Compared with the related art that uses a larger power motor and reduces the heat generation of the motor by the method of a big horse pulling a small cart, it can avoid the problem of increased weight and cost of the whole machine due to the selection of an oversized motor 121. In addition, compared with the related art that reduces the heat generation of the motor by reducing the joint speed, it can ensure the performance of the robot and the utilization rate of the motor 121, meeting the robot's performance, weight and cost requirements.

[0076] like Figure 2 、 Figure 5 and Figure 6 As shown, in some embodiments, optionally, the heat conducting member 140 includes a plurality of heat conducting sheets 141 , and the plurality of heat conducting sheets 141 are stacked and arranged in a direction from the driving assembly 120 to the heat dissipating member 130 .

[0077] In this embodiment, the heat conducting member 140 is defined to include a plurality of heat conducting sheets 141. Specifically, the plurality of heat conducting sheets 141 are stacked and arranged along the direction from the driving component 120 to the heat sink 130. That is, a plurality of heat conducting sheets 141 are filled in the gap between the driving component 120 and the heat sink 130, so that the heat generated by the driving component 120 can be promptly and quickly transferred to the outside of the arm body 110 through the plurality of heat conducting sheets 141 and the heat sink 130, which is beneficial to improving the efficiency of heat transfer, thereby improving the heat dissipation effect of the driving component 120, meeting the heat dissipation requirements while ensuring the performance of the robot.

[0078] It can be understood that the number of heat conducting plates 141 can be determined according to the size of the gap between the driving component 120 and the heat sink 130, so that the heat conducting plates 141 located on both sides of the multiple heat conducting plates 141 can respectively contact the driving component 120 and the heat sink 130 to improve the efficiency of heat transfer.

[0079] Optionally, the heat conductive sheet 141 includes a heat conductive silicone sheet.

[0080] In some embodiments, optionally, the heat sink 130 and the arm body 110 are an integral structure.

[0081] In this embodiment, the heat sink 130 and the arm body 110 are defined as an integrated structure. It is understood that an integrated structure has excellent mechanical properties, thereby improving the connection strength between the heat sink 130 and the arm body 110, which helps ensure effective heat dissipation of the drive assembly 120. Furthermore, the integrated structure facilitates the processing and manufacturing of the arm body 110, thereby reducing the manufacturing difficulty of the arm body 110 and, in turn, the production cost of the robotic arm 100.

[0082] In addition, the arm body 110 is generally a metal part to ensure the overall structural strength of the robotic arm 100. Since the heat sink 130 and the arm body 110 are an integrated structure, that is, the heat sink 130 is also a metal part. It can be understood that the metal part has good thermal conductivity, thereby improving the efficiency of heat transfer and further improving the heat dissipation effect of the drive component 120.

[0083] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the drive assembly 120 includes a motor 121 and a reducer 122, wherein the heat sink 130 is located between the cavity wall of the accommodating cavity 111 and the motor 121, the reducer 122 is connected to the motor 121, and the arm body 110 is connected to the reducer 122.

[0084] In this embodiment, the driving assembly 120 is defined to include a motor 121 and a reducer 122. Specifically, the reducer 122 is connected to the motor 121, and the arm body 110 is connected to the reducer 122. That is, under the drive of the motor 121, the reducer 122 drives the arm body 110 to rotate.

[0085] It is understandable that during the operation of the robot, the motor 121 generates more heat than the reducer 122. By arranging the heat sink 130 between the motor 121 and the wall of the accommodating cavity 111, the heat generated by the motor 121 can be quickly transferred to the outside of the arm body 110 through the heat sink 130, thereby ensuring the heat dissipation effect of the motor 121, meeting the heat dissipation requirements, and helping to further improve the reliability of the robot.

[0086] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 8 As shown, in some embodiments, optionally, the arm body 110 includes a connecting portion 112 , the connecting portion 112 is provided with a receiving cavity 111 , and the robotic arm 100 further includes a rotating seat 150 , which is rotatably connected to the connecting portion 112 .

[0087] In this embodiment, it is defined that the robotic arm 100 also includes a rotating seat 150. Specifically, the arm body 110 includes a connecting portion 112, and the connecting portion 112 is rotatably connected to the rotating seat 150. It can be understood that the rotating seat 150 is rotatably connected to the fixed seat of the robot.

[0088] Since the connection part 112 is provided with a accommodating cavity 111, that is, the driving component 120 is located at the joint of the robot arm 100, a heat sink 130 is provided at the joint to dissipate heat from the driving component 120, so that the heat generated by the driving component 120 can be dissipated in time through multiple heat sinks 131, ensuring the protection level of the robot arm 100 while achieving effective heat dissipation of the driving component 120, reducing the probability of failure of the driving component 120, extending the service life of the driving component 120, and improving the reliability of the robot.

[0089] In some embodiments, optionally, the arm body 110 is a metal part; and / or the heat sink 130 is a metal part.

[0090] In this embodiment, the arm body 110 is specifically constructed of metal, thereby ensuring the overall structural strength of the robotic arm 100. Furthermore, since heat generated by the drive assembly 120 is transferred to the air via the heat sink 130 and the arm body 110, dissipating heat, configuring the arm body 110 as a metal component can improve the efficiency of heat transfer, thereby further enhancing the heat dissipation effect of the drive assembly 120.

[0091] The heat sink 130 is a metal piece, that is, each heat sink 131 is a metal piece. It can be understood that the metal piece has good thermal conductivity, thereby improving the efficiency of heat transfer and further improving the heat dissipation effect of the drive component 120.

[0092] According to a second aspect of the present invention, a robot is provided, comprising a robotic arm 100 as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the robotic arm 100 , which will not be described in detail herein.

[0093] In some embodiments, optionally, there are multiple robotic arms 100, and the multiple robotic arms 100 include at least a first arm and a second arm. The robot also includes a fixed base, and both ends of the first arm are rotatably connected to the fixed base and the second arm respectively.

[0094] In this embodiment, the number of robotic arms 100 is limited to multiple. Specifically, the multiple robotic arms 100 include a first arm and a second arm. One end of the first arm is rotatably connected to the fixed base, and the other end of the first arm is rotatably connected to the second arm. That is to say, if the fixed base is the first joint, the first arm is the second joint, and the second arm is the third joint.

[0095] It is understandable that in most actual application conditions, the A2 and A3 axes of the robot are subjected to the most complex stress conditions, are used most frequently, and generate the most heat. Heat sinks 130 are respectively provided in the accommodating cavity 111 of the first arm and the accommodating cavity 111 of the second arm to dissipate heat from the drive assembly 120. That is, heat sinks 130 are provided in locations of the robot that generate more heat for heat dissipation, thereby achieving effective heat dissipation during the robot's operation, meeting the heat dissipation requirements, and helping to reduce the production cost of the robot.
