Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and more particularly to a manipulator with no turning radius and a robot having the same. Background Art

[0002] In the field of manipulators, the existing manipulation technologies have achieved remarkable development, but there are still some limitations in practical applications. Traditional manipulators usually adopt a multi-joint structure, and their motion control depends on complex kinematic and dynamic models. Although this design can achieve a certain degree of flexibility, their operation ability in narrow spaces or complex environments is still limited. For example, when a manipulator executes a task, it often needs to reserve a large turning radius to complete motion conversion, which not only increases the complexity of the motion path but also may lead to difficulties in operation in narrow areas. In addition, the motion control of a manipulator usually needs to be achieved through complex programming or a control interface, and the operation is not intuitive enough. For dynamically changing task requirements, its adaptability and flexibility are insufficient.

[0003] In terms of precise positioning and high-precision docking, existing manipulators also face challenges. Due to factors such as elastic deformation of the mechanical structure, transmission errors, and sensor accuracy, it is very difficult for the end effector of a manipulator to achieve a positioning accuracy of millimeters or even higher. This becomes a key bottleneck in scenarios that require high-precision operations (such as precision assembly, complex surface treatment, etc.). At the same time, during the movement of the end effector of a manipulator, its attitude adjustment ability is limited and it is difficult to be optimized in real time according to task requirements.

[0004] For example, in the field of indoor decoration, these limitations are particularly obvious. Decoration operations usually involve complex environments and diverse task requirements, such as wall painting, putty scraping, tile laying, etc. These tasks not only require the manipulator to be able to flexibly adapt to construction areas of different shapes and sizes but also need to achieve dead-angle-free operation at narrow corners. However, due to the large turning radius of existing manipulators, it is difficult to perform precise operations in narrow areas such as wall corners and window edges, resulting in low construction efficiency and difficult quality assurance. For example, in the putty scraping process on the wall, traditional manipulators need to move the base to switch construction areas, which not only increases the construction time and equipment complexity but also easily leaves obvious seams between adjacent areas. In wall painting, due to the inflexible motion control of the manipulator, it is unable to make real-time adjustments according to the complex shape of the wall, resulting in uneven or missed spraying. Especially when dealing with defects such as wall pits and cracks, it is difficult to achieve an ideal coverage effect.

[0005] In summary, the existing manipulator control technologies have obvious deficiencies in terms of motion flexibility, accuracy, and operation convenience. Especially in the field of interior decoration, these problems seriously affect the application effect and promotion value of manipulators. Therefore, developing a new type of manipulator control system to overcome the limitations of existing technologies and meet the requirements of efficient, accurate, and flexible operations in the decoration field is an urgent problem to be solved in this field.

[0061] Example 1:

[0062] Referring to FIGS. Figures 1-5 8, 12, 13, 21 and 22, an embodiment of the present invention discloses a control manipulator without turning radius, including: a control mechanism 10 and a robot arm 4;

[0063] The control mechanism 10 includes: a mounting plate 11, a synchronous pulley 21, a synchronous belt 22, a support frame 12, a connecting frame 31, and a control head 32; on the first plate surface of the mounting plate 11, there is a rectangular movement path 112 formed by connecting four turning points 111 arranged in an array; the number of synchronous pulleys 21 is four, and the four synchronous pulleys 21 are respectively arranged corresponding to the four turning points 111, and are all rotatably connected to the first plate surface of the mounting plate 11; the synchronous belt 22 is sleeved outside the four synchronous pulleys 21; the support frame 12 is detachably connected to the mounting plate 11, and a support groove 121 corresponding to the movement path 112 is provided on the inner wall surface of the support frame 12; the connecting frame 31 is detachably connected to the synchronous belt 22; the control head 32 is rotatably connected to the connecting frame 31, the rotation axis of the control head 32 is arranged parallel to the synchronous pulley 21, and the projection of the rotation axis of the control head 32 along the direction perpendicular to the first plate surface is located on the movement path 112; a plurality of sliding brackets 34 are fixedly connected to the control head 32, and when the control head 32 moves along any side line of the rectangular movement path 112, two sliding brackets 34 are slidably connected to the support groove 121 corresponding to this side line;

[0064] The mobile end of the robotic arm 4 is detachably connected to the second plate surface of the mounting plate 11.

[0065] Specifically, the mounting plate 11 is provided with a plurality of first weight reduction holes 116.

[0066] See the appendix Figure 2 , and further includes a fixing bracket 13. One end of the fixing bracket 13 is fixedly connected to the support frame 12, and the other end is detachably connected to the side wall surface of the mounting plate 11.

[0067] See the appendix Figure 9 , the fixing bracket 13 includes a fixing bracket one 131 and a fixing bracket two 132. The number of the fixing brackets one 131 is two, and they are symmetrically arranged about the center in the width direction of the support frame 12; the number of the fixing brackets two 132 is two, and they are symmetrically arranged about the center in the length direction of the support frame 12. The width of the fixing bracket one 131 is greater than the width of the fixing bracket two 132 to provide stronger anti-torsion stiffness in the length direction of the support frame 12.

[0068] See the appendix Figures 4-8, the connecting frame 31 includes a positioning post 311 arranged perpendicular to the first plate surface. The interior of the control head 32 has a receiving cavity 323. The working end of the control head 32 has four output ports 324 arranged circumferentially and all communicating with the receiving cavity 323. One end of the control head 32 facing away from the working end is provided with a rotation hole 3221 communicating with the receiving cavity 323. The positioning post 311 is rotatably connected to the rotation hole 3221 through a dynamic seal. A supply port 3222 communicating with the receiving cavity 323 is provided on the side wall surface of the control head 32. The end surface of the positioning post 311 located inside the receiving cavity 323 is detachably connected with a distribution plate 33. A notch 331 is provided on the edge of the distribution plate 33. During the rotation of the distribution plate 33, the receiving cavity 323 is selectively communicated with the four output ports 324. Thus, by detachably connecting the distribution plate 33 with the positioning post 311, during the movement of the connecting frame 31 along with the synchronous belt 22, when passing through a corner, the connecting end of the connecting frame 31 and the synchronous belt 22 rotates along the axis of the synchronous pulley 21. At this time, the axis of the positioning post 311 is coaxial with the synchronous pulley 21 at this place. Furthermore, the distribution plate 33 rotates along the axis of the synchronous pulley 21 at this place, and the notch 331 also switches to the output port 324 in the advancing direction, making the whole structure have the characteristic that the output port 324 automatically changes direction along with the change of direction of the control head 32.

[0069] See the appendix Figure 20 , a first threaded hole 315 is provided on the end surface of the positioning post 311 located inside the receiving cavity 323. The distribution plate 33 is coaxially arranged with the positioning post 311 and is provided with a threaded through hole and a screw head counterbore corresponding to the first threaded hole 315.

[0070] Specifically, the connecting frame 31 is provided with a coaxial first screw through hole 313 and a first screw counterbore 314 in a direction perpendicular to the axis of the positioning post 311. First pin holes 318 are symmetrically arranged on both sides of the first screw through hole 313. A fixing block is fixedly connected to the outer ring surface of the synchronous belt 22, and a threaded bottom hole and a pin bottom hole corresponding to the first screw through hole 313 and the first pin holes 318 are respectively provided on the fixing block.

[0071] Specifically, a second weight reduction hole 319 is provided along the axial position of the positioning post 311.

[0072] See the appendix Figure 6 , the output ports 324 are communicated with the receiving cavity 323 through three radially arranged output pipes 325. The width of the notch 331 corresponds to the total width of the input ends of the three output pipes 325. Thus, the design of the radially arranged output pipes 325 can ensure the uniform distribution of materials or tools inside the control head 32 and improve the uniformity and consistency of operations.

[0073] See the appendix Figures 14-16, the projection of the control head 32 on the plane perpendicular to the mounting plate 11 is a square. The control head 32 includes a control head base 322 and a cover plate 321. The end face of the control head base 322 facing the mounting plate 11 is the first end face, and the end face of the control head base 322 facing away from the mounting plate 11 is the second end face.

[0074] Specifically, the output pipe 325 is composed of a first half-output pipe 3224 opened on the control head base 322 and a second half-output pipe 3213 opened on the cover plate 321.

[0075] See attached Figure 8 , four positioning grooves 3223 are arranged in a circular array along the center of the first end face of the control head base 322. The number of sliding brackets 34 is four. The four sliding brackets 34 respectively correspond to the four positioning grooves 3223 and are fixedly connected to the control head base 322 by screws.

[0076] At the center position of the second end face of the control head base 322, there is a square boss. A radial first half-output pipe 3224 is opened on the boss. A cylindrical receiving groove 3226 is opened at the center position of the boss. A third threaded hole 3227 is opened at the corner position of the boss. The second end face is provided with a partition 3228 along its diagonal line to divide the circumferential area of the boss. A rotating hole 3221 penetrating the first end face is opened at the center position of the bottom surface of the receiving groove 3226. A rotating ring groove 3225 is opened at the edge position of the receiving groove 3226. A supply port 3222 is opened on the side wall surface of the control head base 322.

[0077] On the opposite surfaces of the cover plate 321 and the control head base 322, there are rotating grooves 3214 arranged corresponding to the rotating ring groove 3225, and second half-output pipes 3213 arranged corresponding to the first half-output pipe 3224. On the opposite surfaces of the cover plate 321 and the control head base 322, there are second screw through holes 3211 and second screw countersinks 3212 arranged corresponding to the third threaded hole 3227.

[0078] Specifically, the first half-output pipe 3224 opened on the control head base 322 and the second half-output pipe 3213 opened on the cover plate 321 constitute the output pipe 325.

[0079] See attached Figure 17 , the sliding bracket 34 includes a support plate 341 and a limit post 342. The support plate 341 is arranged in an L shape, and its corner point faces the corner position of the control head base 322. The limit post 342 is arranged perpendicular to the second end face of the control head base 322 and is fixedly connected to the corner point of the support plate 341. The limit post 342 contacts and abuts against the inner wall surface of the support groove 121.

[0080] See attached Figure 10 、11 , 21-23, a support groove through hole 122 perpendicular to the support groove 121 is provided on the inner wall surface of the support frame 12, and two support groove through holes 122 are provided on the four side wall surfaces of the four side lines of the support frame 12 corresponding to the movement path 112, the two support groove through holes 122 corresponding to the long side of the movement path 112 are symmetrically arranged about the center position of the support frame 12 along its length direction, and the two support groove through holes 122 corresponding to the short side of the movement path 112 are symmetrically arranged about the center position of the support frame 12 along its width direction, and the distance between the support groove through hole 122 and the bottom surface of the support groove 121 close to it corresponds to the distance between the two limit columns 342.

[0081] More specifically, the supporting groove through hole 122 is arranged corresponding to the contour of the axial cross section of the limiting column 342 .

[0082] See attached Figure 5 , 18 -20 and 24, and also include a stabilizing wheel assembly 35, which includes a roller bracket 351 and two rollers 352 arranged in parallel and at intervals, a mounting groove 312 is provided at the end of the connecting frame 31, the first end of the roller bracket 351 is detachably connected to the mounting groove 312, an annular stabilizing groove 114 is provided on the first plate surface of the mounting plate 11, the two rollers 352 are arranged in parallel with the positioning column 311, the two rollers 352 are rotatably connected to the second end of the roller bracket 351, and the two rollers 352 are in contact with the side wall surface of the stabilizing groove 114. Therefore, the stabilizing wheel assembly 35 can effectively reduce the shaking of the control head 32 during the movement, and the contact and abutment between the rollers 352 and the stabilizing groove 114 provides a precise guiding effect for the control head 32, further improving the accuracy of the motion trajectory.

[0083] Specifically, a second threaded hole 316 and a second pin hole 317 are formed on the side wall surface of the connecting frame 31 corresponding to the mounting groove 312 .

[0084] Specifically, a third screw through hole 3512 and a third pin hole 3511 are formed at the first end of the roller bracket 351 , which are respectively arranged corresponding to the second threaded hole 316 and the second pin hole 317 .

[0085] See attached Figure 2 and Figure 5 , and further includes a servo motor 23. The mounting plate 11 is provided with an avoidance hole. The fixed end of the servo motor 23 is fastened to the second plate surface of the mounting plate 11, and the power output end of the servo motor 23 passes through the avoidance hole and is fastened to any synchronous pulley 21. Thus, the servo motor 23 can achieve high-precision motion control, ensuring that the control head 32 moves according to the set trajectory and speed, thereby improving the accuracy and reliability of the operation.

[0086] See attachedFigure 2 , further comprising a connecting plate 14. One surface of the connecting plate 14 is fixedly connected to the mounting plate 11, and the other surface is detachably connected to the robotic arm 4. Thus, the arrangement of the connecting plate 14 enables the control mechanism 10 to be conveniently installed on different types of robotic arms, improving the versatility and expandability of the device. The detachable connection facilitates the disassembly and maintenance of the control mechanism 10 and the robotic arm 4, reducing the maintenance cost of the device.

[0090] The fixed end of the robotic arm 4 is fixedly connected to the load-carrying frame 51.

[0091] Thus, through the design of the mobile chassis 5, the robot can quickly switch between different areas, further improving the flexibility and application range of the device.

[0092] To further optimize the above technical solution, it further includes a supply tank 6. The supply tank 6 is fixedly connected to the loading surface of the load-carrying frame 51, and the supply tank 6 is connected to the control head 32 through a pipeline. Thus, through the continuous supply of the supply tank 6, the robot can achieve continuous operation, improving the work efficiency.

[0093] Specifically, the output end of the supply tank 6 is connected to the supply port 3222 through a pipeline.

[0094] To further optimize the above technical solution, it further includes a controller, which is electrically connected to the control modules of the mobile chassis 5, the control mechanism 10, the robotic arm 4, and the supply tank 6. Thus, the controller can dynamically adjust the operating parameters of each module according to the task requirements, enhancing the adaptability of the device to dynamically changing tasks.

[0095] The specific principle and usage method of the control manipulator without turning radius provided in this embodiment are as follows:

[0096] 1. The mobile chassis 5 moves to the front of the wall to be constructed. The robotic arm 4 is controlled by the controller to keep the control mechanism 10 parallel to the wall to be constructed and maintain a certain gap. The supply tank 6 is controlled by the controller to start supplying materials to the control head 32;

[0097] 2. Start the servo motor 23. The servo motor 23 drives the synchronous belt 22 to rotate, and the synchronous belt 22 drives the control head 32 to perform Figure 25Counterclockwise movement in the indicated orientation. When the axial direction of the positioning post 311 is about to move to be coaxial with the synchronous pulley 21 in the upper left corner, the limiting post 342 corresponding to the sliding bracket 34 in the lower left corner enters the support groove 121 through the support groove through-hole 122 above the left inner wall surface of the support frame 12;

[0098] 3. As Figures 26-28 shown, when the control head 32 moves to the synchronous pulley 21 in the upper left corner, the control head 32 pauses briefly. The second end of the connecting frame 31 rotates along the axis of the synchronous pulley 21 with the synchronous belt 22 on the outer periphery of the synchronous pulley 21 in the upper left corner, driving the material distribution plate 33 to rotate, and tilting the notch 331 perpendicular to the left direction downward along the axis of the synchronous pulley 21 in the upper left corner;

[0099] 4. As Figure 29 shown, when the second end of the connecting frame 31 moves with the synchronous belt 22 to the tangent position along the vertical direction of the outer periphery of the synchronous pulley 21 in the upper left corner, the direction of the notch 331 is completely downward;

[0100] 5. The synchronous belt 22 continues to move, driving the control head 32 to move downward. At the same time, the limiting post 342 corresponding to the sliding bracket 34 in the upper right corner exits from the support groove 121 through the support groove through-hole 122 on the left side of the upper inner wall surface of the support frame 12. When the control head 32 moves one week along the movement path 112, the construction area is completed with smearing;

[0101] 6. The controller controls the robotic arm 4 to switch the control mechanism 10 to the next construction area.

[0102] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
