Description

Technical Field

[0001] This application relates to the field of robotics, and more particularly to a drive structure for a hair-drying robot and the hair-drying robot itself. Background Technology

[0002] A robotic arm is a programmable mechanical device, typically composed of multiple joints and links, capable of mimicking the functions of a human arm to perform tasks such as grasping, handling, welding, and assembly. Within the joints of a robotic arm, there are usually drive components that output torque to rotate adjacent links, achieving directional movement. Because of their direct and precise drive mechanism, motors are frequently used as drive components within robotic arms. For example, a hair-drying robot is a robot that automatically dries hair by connecting a hairdryer to a multi-stage robotic arm, which then adjusts the hairdryer's position to complete the drying action. Motors can be assembled on these multi-stage robotic arms, driving the movement of the next stage of the robotic arm.

[0003] However, the performance of direct-drive motors is directly proportional to their size. To meet the movement requirements of robotic arms, large-sized motors are often needed. In some working environments, such as hair-drying robots, the space occupied and manufacturing cost of the robotic arm must be considered. Therefore, existing robotic arms are not suitable for the working environment of hair-drying robots due to their high production costs and large space requirements.

[0044] Please refer to Figure 1 and Figure 2 In one embodiment of this application, a drive structure 1 for a hair blower robot is disclosed, including a mounting frame 10, and a motor 20, an intermediate shaft 30, and a drive shaft 40 disposed on the mounting frame 10. The motor 20 and the intermediate shaft 30 are connected by a primary transmission assembly 50; the intermediate shaft 30 and the drive shaft 40 are connected by a secondary transmission assembly 60; wherein, both the primary transmission assembly 50 and the secondary transmission assembly 60 are used to amplify torque.

[0045] The drive structure 1 disclosed in this embodiment is used for a hair blower robot. The drive structure 1 can be set at the joint of the hair blower robot and connected to the adjacent robotic arm. The torque output by the drive structure 1 can drive the adjacent robotic arm to rotate.

[0046] Specifically, in this embodiment, a small-volume motor 20 is used as the power source. Through a two-stage transmission system consisting of the motor 20, a primary transmission assembly 50, and a secondary transmission assembly 60, the torque on the output shaft of the motor 20 is transmitted to the intermediate shaft 30, and further transmitted through the intermediate shaft 30 to the drive shaft 40. This results in a large torque on the drive shaft 40, providing stronger power and enabling it to drive larger loads. Therefore, the drive structure 1 disclosed in this embodiment can balance the requirements of product performance and product size, and is suitable for use in the working environment of hair-drying robots.

[0047] Specifically, the motor 20 disclosed in this embodiment includes, but is not limited to, any one of a DC motor 20, a stepper motor 20, and a servo motor 20.

[0048] Please refer to Figure 3 As another embodiment of this application, the primary transmission assembly 50 is disclosed to include a driving wheel 51, a driven wheel 52, a first synchronous belt 53 and a first tensioning wheel 54. The driving wheel 51 is sleeved on the output shaft of the motor 20; the driven wheel 52 is sleeved on the intermediate shaft 30; one end of the first synchronous belt 53 is sleeved on the driving wheel 51 and the other end is sleeved on the driven wheel 52.

[0049] In this embodiment, a first synchronous belt 53 connects the driving pulley 51 and the driven pulley 52, allowing them to rotate simultaneously. Therefore, when the motor 20 starts, its output shaft drives the driving pulley 51 to rotate. The friction between the driving pulley 51 and the first synchronous belt 53 causes the first synchronous belt 53 to move, and the friction between the first synchronous belt 53 and the driven pulley 52 causes the driven pulley 52 to also begin rotating, thus transmitting power. This transmission method is simple, compact, and highly efficient.

[0050] Specifically, in this embodiment, the first tensioning pulley 54 is disposed on the mounting bracket 10, located between the driving pulley 51 and the driven pulley 52; the first tensioning pulley 54 is disposed on the outside of the first synchronous belt 53 and abuts against the first synchronous belt 53. By setting the first tensioning pulley 54, the lateral vibration of the first synchronous belt 53 caused by high-speed movement can be suppressed, ensuring that the first synchronous belt 53 is in close contact with the driving pulley 51 and the driven pulley 52 throughout the entire process, avoiding instantaneous misalignment caused by slippage, improving the stability of operation, and also reducing noise.

[0051] Specifically, in this embodiment, the diameter of the driving wheel 51 is smaller than the diameter of the driven wheel 52. By setting the diameter of the driving wheel 51 to be smaller than that of the driven wheel 52, the rotational speed of the driven wheel 52 decreases, but the torque increases. The reduction and torque increase effect is achieved by utilizing the ratio of the wheel diameters, thereby reducing the instantaneous load on the motor 20 and enabling the output torque of the motor 20 to be amplified several times to tens of times.

[0052] Specifically, the diameter of the driving wheel 51 disclosed in this embodiment can be one-quarter, one-third, or one-half of the diameter of the driven wheel 52, and can be flexibly set according to the working requirements of the product. It should be noted that the diameters of the driving wheel 51 and driven wheel 52 disclosed in this embodiment are just examples. Other sizes of driving wheels 51 and driven wheels 52, as long as they can achieve the technical effects disclosed in this application, can be considered as equivalent substitutions for the inventive concept and should also be within the scope of protection of this application.

[0053] Specifically, in this embodiment, the first synchronous belt 53 can be a rubber belt, and the driving pulley 51 and the driven pulley 52 can be set as pulleys or synchronous gears. Protrusions are provided on the circumferential surfaces of the driving pulley 51 and the driven pulley 52 to increase friction, thereby reducing the slippage of the first synchronous belt 53 and improving the accuracy of transmission.

[0054] Please refer to Figure 4 As another embodiment of this application, a pretensioning rib 70 is provided on the mounting bracket 10. The pretensioning rib 70 is disposed opposite to the first tensioning wheel 54 and is located on the side of the first synchronous belt 53 away from the first tensioning wheel 54. A guide surface is provided on the side of the pretensioning rib 70 facing the first synchronous belt 53. The guide surface is tangent to both the driving wheel 51 and the driven wheel 52 and is used to pretension the first synchronous belt 53.

[0055] In this embodiment, the first synchronous belt 53 needs to be kept taut even when stationary to prevent it from loosening. This is achieved by setting pretensioning ribs 70 attached to the outer side of the first synchronous belt 53. At this time, the first synchronous belt 53 is constrained by the guide surface, extending from the driving pulley 51 to the driven pulley 52. ​​The guide surface and the first tensioning pulley 54 are simultaneously attached to the first synchronous belt 53, providing a pretensioning effect, keeping the first synchronous belt 53 stable, and reducing the problem of tooth skipping.

[0056] Specifically, the pretensioning rib 70 disclosed in this embodiment can be directly formed on the mounting bracket 10, or it can be locked onto the mounting bracket 10 by screws. Preferably, a relatively long screw can be provided, with a redundant length, so as to further screw in the screw to adjust the position of the pretensioning rib 70, so that the pretensioning rib 70 and the first synchronous belt 53 are kept in close contact, providing stable support and preventing loosening.

[0057] Please refer to this again. Figure 3 and Figure 4 As another embodiment of this application, the secondary transmission assembly 60 is disclosed to include a transition wheel 61, an end wheel 62, a second synchronous belt 63, and a second tensioning wheel 64. The transition wheel 61 is sleeved on the intermediate shaft 30; the end wheel 62 is sleeved on the drive shaft 40; one end of the second synchronous belt 63 is sleeved on the transition wheel 61, and the other end is sleeved on the driven wheel 52.

[0058] The secondary transmission assembly 60 disclosed in this embodiment further amplifies the torque. The transition wheel 61 is mounted on the intermediate shaft 30, so it rotates synchronously with the driven wheel 52, maintaining the same angular velocity. Simultaneously, the transition wheel 61 is connected to the end wheel 62 via the second synchronous belt 63. Therefore, when the driven wheel 52 is rotated by the first synchronous belt 53, the intermediate shaft 30 rotates, and the transition wheel 61 rotates synchronously. The friction between the transition wheel 61 and the second synchronous belt 63 drives the second synchronous belt 63 to move, and the friction between the second synchronous belt 63 and the end wheel 62 causes the end wheel 62 to rotate, ultimately causing the drive shaft 40 to rotate.

[0059] Specifically, in this embodiment, the second tensioning wheel 64 is disposed on the mounting bracket 10, located between the transition wheel 61 and the end wheel 62; the second tensioning wheel 64 is disposed on the outside of the second synchronous belt 63 and abuts against the second synchronous belt 63.

[0060] By setting a second tensioning pulley 64, the lateral vibration of the second synchronous belt 63 caused by high-speed movement can be suppressed, ensuring that the second synchronous belt 63 is in close contact with the transition pulley 61 and the end pulley 62 throughout the entire process, avoiding instantaneous misalignment caused by slippage, further improving the stability of the operation, and also reducing noise.

[0061] Specifically, in this embodiment, the diameter of the transition wheel 61 is smaller than the diameter of the end wheel 62. By setting the diameter of the transition wheel 61 to be smaller than the diameter of the end wheel 62, a speed reduction and torque increase effect can be achieved by utilizing the ratio of the wheel diameters, thus amplifying the output torque on the intermediate shaft 30 by several to tens of times.

[0062] In summary, the secondary transmission component 60 disclosed in this embodiment can adopt the same structure as the primary transmission component 50, further amplifying the torque and driving the small-volume motor 20. This helps reduce the size of the robotic arm and meets the usage requirements of the hair-drying robot. Furthermore, by simultaneously setting the primary transmission component 50 and the secondary transmission component 60, bipolar deceleration is achieved, dispersing load impact and avoiding deformation problems that may occur with single-stage transmission.

[0063] Specifically, the diameter of the transition wheel 61 disclosed in this embodiment can be set to one-fifth, one-quarter, one-third, or one-half of the diameter of the end wheel 62, and can be flexibly set according to working needs. It should be noted that the diameters of the driven wheel 52 and the end wheel 62 disclosed in this embodiment are just examples. Other sizes of driven wheels 52, as long as they can achieve the technical effects disclosed in this application, can be considered as equivalent substitutions for the inventive concept and should also be within the scope of protection of this application.

[0064] Please refer to Figure 3 In this embodiment, the diameter of the transition wheel 61 is smaller than the diameter of the driven wheel 52. Both the transition wheel 61 and the driven wheel 52 are mounted on the intermediate shaft 30. During startup, the frictional resistance between the transition wheel 61 and the second synchronous belt 63, and the frictional resistance between the driven wheel 52 and the first synchronous belt 53, both affect the rotation of the motor 20. Making the diameter of the transition wheel 61 smaller helps reduce friction and rotational inertia, making startup easier. In other words, it reduces the driving force required for the motor 20 to start, resulting in a faster response speed and improved control accuracy.

[0065] Please refer to Figure 2 and Figure 3 As another embodiment of this application, the drive structure 1 is disclosed to include a first bearing 80 and a second bearing 90, which are spaced apart on the intermediate shaft 30. The first bearing 80 is located between the driven wheel 52 and the transition wheel 61; the second bearing 90 is located on the side of the transition wheel 61 opposite to the driven wheel 52. By providing the first bearing 80 and the second bearing 90, friction can be reduced, ensuring that the driven wheel 52, the transition wheel 61, and the intermediate shaft 30 can rotate smoothly under high speed or load conditions, while isolating the influence of radial / axial forces on the motor 20 or other structures.

[0066] Please refer to this again. Figure 2 and Figure 3 As another embodiment of this application, the drive structure 1 is disclosed to include at least two third bearings 100, which are spaced apart on the drive shaft 40. By providing the third bearings 100, friction can be reduced, ensuring that the end wheel 62 and the drive shaft 40 can rotate smoothly under high speed or load. The transition wheel 61, the end wheel 62 and the second synchronous belt 63 are precisely meshed, reducing shaft wobbling and avoiding tooth skipping or slippage. At the same time, the influence of radial / axial forces on the motor 20 or other structures is isolated.

[0067] Please refer to Figure 3As another embodiment of this application, the drive shaft 40 is provided with a through hollow channel 41 along the axial direction, the hollow channel 41 being used to arrange wires; the drive structure 1 includes a guide plate 110 disposed on the mounting bracket 10, the guide plate 110 being disposed directly opposite the hollow channel 41; and the guide plate 110 is provided with a guide hole 111, the guide hole 111 being coaxially disposed with the hollow channel 41, for introducing wires into the hollow channel 41.

[0068] The drive structure 1 disclosed in this embodiment is applied to a hair drying robot. The drive shaft 40 is connected to the adjacent robotic arm. Therefore, a hollow channel 41 for wiring can be set in the drive shaft 40 so that the robot's wiring can be arranged along the robotic arm and the wires can be hidden inside the robotic arm.

[0069] Specifically, in this embodiment, the drive shaft 40 is rotatable. Therefore, a guide plate 110 is set at one end of the drive shaft 40, facing the hollow channel 41. The wire is introduced into the hollow channel 41 through the guide hole 111, which can fix the position of the wire, reduce the contact friction between the wire and the drive shaft 40, protect the wire and the drive shaft 40, stabilize the internal structure of the robot, and increase the safety of long-term use.

[0070] Please refer to Figure 5 and Figure 6 As another embodiment of this application, a hair-drying robot is also disclosed, which includes a mounting shell 2, a control component 3, and a drive structure 1 as described above. The control component 3 is disposed in the middle of the mounting shell 2. There are two drive structures 1, which are symmetrically disposed on both sides of the control component 3. Both drive structures 1 are electrically connected to the control component 3.

[0071] The hair-drying robot disclosed in this embodiment places the control component 3 in the middle of the mounting shell 2 and symmetrically arranges the two drive structures 1 on both sides of the control component 3, so that the mass distribution inside the mounting shell 2 is uniform and the center of gravity is kept in the middle position of the mounting shell 2, which is beneficial to stability. During use, one end of the mounting shell 2 can be connected to the fixed bracket of the upper-level robotic arm, and the other end can be connected to the lower-level robotic arm, so that the drive structure 1 disclosed in this application can rotate relative to the fixed bracket, driving the lower-level robotic arm to rotate.

[0072] Please refer to Figure 6 As one embodiment of this invention, the control component 3 is disclosed to include a back plate 31 and a circuit board 32. The back plate 31 is integrally formed with the two mounting brackets 10; the circuit board 32 is electrically connected to the two motors 20.

[0073] The circuit board 32 disclosed in this embodiment includes, but is not limited to, a printed circuit board. The circuit board 32 is used to connect to the motor 20 and control the starting and stopping of the motor 20. Meanwhile, in this embodiment, the circuit board 32 is supported by a back plate 31, isolating the circuit board 32 from the mounting housing 2, which protects the circuit board 32, reduces circuit failures, and avoids safety hazards.

[0074] Based on this, in this embodiment, by integrally molding the back plate 31 with the two mounting brackets 10 of the two drive structures 1, the internal structure of the hair drying robot can be further simplified, which is conducive to integrated manufacturing, simplifies the assembly process, and reduces production costs.

[0075] Please refer to Figure 4 In another embodiment of this invention, a magnetic interface 21 is provided at the bottom of the mounting shell 2. The hair-drying robot disclosed in this embodiment can connect external accessories by providing the magnetic interface 21, and connect the external accessories to the internal control unit 3 to achieve more functions.

[0076] For example, a magnetic fill light can be plugged into the magnetic interface 21 to achieve a lighting fill effect.

[0077] In summary, this application discloses a drive structure 1 for a hair-drying robot, including a mounting frame 10, and a motor 20, an intermediate shaft 30, and a drive shaft 40 mounted on the mounting frame 10. The motor 20 and the intermediate shaft 30 are connected via a primary transmission assembly 50; the intermediate shaft 30 and the drive shaft 40 are connected via a secondary transmission assembly 60. Both the primary transmission assembly 50 and the secondary transmission assembly 60 are used to amplify torque. Through the two-stage transmission of the motor 20, the primary transmission assembly 50, and the secondary transmission assembly 60, high torque output is achieved, balancing the requirements for product performance and size during production, making it suitable for the working environment of hair-drying robots.
