Description

Technical Field

[0001] This invention relates to the field of robotics, specifically to a fixed rotating base for processing humanoid robot arms. Background Technology

[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom robotic devices widely used in industrial fields. They possess a certain degree of autonomy and can perform various industrial processing and manufacturing functions using their own power and control capabilities. Industrial robots are widely used in various industrial sectors such as electronics, logistics, and chemicals. When manufacturing a robot arm, multiple processing steps are required. Using a fixed rotating base allows the industrial robot to rotate at any angle on a horizontal plane.

[0003] However, when using existing fixed rotating bases for industrial robots, the output shaft of the drive motor needs to rotate the entire industrial robot, which causes the output shaft to be subjected to high stress and heat generation. In order to reduce the temperature of the rotating base, an air-cooling heat dissipation structure is usually installed inside the rotating base.

[0004] In the metal cutting or grinding processes of humanoid robotic arms, the environment is often filled with a large amount of fine conductive metal dust. Traditional air-cooled heat dissipation inlets are only blocked by filters, which do not have physical sealing capabilities when the equipment is stopped. This allows conductive metal dust to easily penetrate into the rotating base through the mesh and adhere to the stator or drive circuit board of the servo motor. This not only reduces heat dissipation capacity but also easily causes serious engineering failures such as internal circuit short circuits and insulation failures.

[0005] Therefore, the present invention proposes a fixed rotating base for processing humanoid robot arms to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0006] In view of the above problems, the present invention provides a fixed rotating base for processing humanoid robot arms, which can effectively solve the problem in the prior art where fine impurities accumulate inside the rotating base over a long period of time, leading to reduced heat dissipation. To achieve the above objective, the embodiments of this application provide the following technical solution: This invention discloses a fixed rotating base for processing humanoid robot arms, including a rotating base body. The rotating base body has a shielding mechanism on its side to reduce the entry of external impurities. The shielding mechanism has a deflection mechanism inside to change the airflow direction. The rotating base body has a heat absorption mechanism inside, and the heat absorption mechanism has a servo mechanism inside to drive the shielding mechanism. The shielding mechanism includes an air inlet and an air outlet symmetrically provided on the side of the rotating base body. A rectangular frame is fixedly connected to the air inlet, and a filter screen is fixedly connected to the air outlet. A fan that blows air into the rotating base body is fixedly connected inside the rectangular frame. Multiple first rotating shafts are also equidistantly rotatably connected inside the rectangular frame, and the first rotating shafts are arranged horizontally inside the rectangular frame. A baffle is fixedly connected to the outside of each first rotating shaft, and adjacent baffles overlap each other.

[0007] Furthermore, one end of each of the first rotating shafts extends outside the rectangular frame, and a first lever is fixedly connected to the extended end of the first rotating shaft. A first groove is provided at the end of each first lever away from the first rotating shaft, and a first slider is slidably connected inside the first groove. A connecting rod is fixedly connected to the same end of multiple first sliders.

[0008] Furthermore, a first push rod is fixedly connected to the side of the connecting rod, the first push rod extends into the interior of the rotating seat body, and the first push rod is slidably connected to the rotating seat body.

[0009] Furthermore, the rectangular frame is symmetrically fixedly connected to fixed blocks, and sliding rods are fixedly connected between the fixed blocks. The sliding rods are slidably connected to both ends of the first push rod.

[0010] Furthermore, the deflection mechanism includes a second rotating shaft that is symmetrically and rotatably connected to the inside of the rectangular frame, and the second rotating shaft is arranged vertically inside the rectangular frame. Each second rotating shaft is fixedly connected to a partition plate, and each partition plate has multiple ventilation holes on its surface.

[0011] Furthermore, each of the second rotating shafts is externally fixedly connected to a second lever, and a second sliding groove is provided at the end of the second lever away from the second rotating shaft. A second slider is slidably connected inside the second sliding groove, and a crossbar is fixedly connected to the top of the two second sliders. A second push rod is fixedly connected to the side of the crossbar.

[0012] Furthermore, a support frame is fixedly connected to the side of the rectangular frame near the interior of the rotating seat body. The bottom of the support frame is slidably connected to the second push rod. A roller is rotatably connected to the end of the second push rod away from the crossbar. A protrusion is fixedly connected to the outside of the rotating shaft inside the rotating seat body. The protrusion is rotatably connected to the roller. A first limiting block is fixedly connected to the top of the second push rod. A W-shaped elastic sheet is fixedly connected to the side of the first limiting block. The other end of the elastic sheet is fixedly connected to the side of the rectangular frame.

[0013] Furthermore, the heat absorption mechanism includes a housing that is attached to the outside of the rotating shaft inside the rotating seat body, and the bottom of the housing is attached to the top of the motor inside the rotating seat body. The back of the housing is filled with a phase change material, and a plurality of first fins are fixedly connected to the side of the housing.

[0014] Furthermore, the servo mechanism includes a cylinder fixedly connected inside the housing and extending outside the housing. The cylinder is wrapped with a phase change material, and a second fin is fixedly connected to the outside of the cylinder. A piston plate is slidably connected in the cavity inside the cylinder. Solid paraffin wax is filled between the piston plate and the bottom of the cylinder. An L-shaped piston rod is fixedly connected to the side of the piston plate away from the paraffin wax. The end of the L-shaped piston rod away from the piston plate is fixedly connected to the end of the first push rod away from the connecting rod.

[0015] Furthermore, the servo mechanism also includes a second limiting block fixedly connected to the outside of the first push rod, and the second limiting block is located inside the rotary seat body. A reset spring for pushing the L-shaped piston rod to move into the cylinder is fixedly connected to the side of the second limiting block, and the end of the reset spring away from the second limiting block is fixedly connected to the inner wall of the rotary seat body.

[0016] The beneficial effects of this invention are as follows: 1. This device is equipped with a shielding mechanism. Multiple baffles at the air inlet are in a stacked and closed state at room temperature, forming a barrier to prevent external processing dust from entering the interior of the rotating seat. When the internal temperature rises, the expansion of paraffin wax overcomes the spring resistance and pushes the baffles open to allow ventilation. This ensures the heat dissipation requirements of the motor while reducing the amount of fine particles deposited on the internal substrate when the machine is stopped.

[0017] 2. This device is equipped with a deflection mechanism. When the internal rotating shaft rotates, the protrusion periodically pushes the roller and push rod. With the reset action of the W-shaped elastic plate, the partition is driven to swing back and forth around the vertical second rotating shaft. When the airflow passes through the multiple vents on the partition, the airflow direction will be continuously deflected with the swing of the partition, so that the cold air can be blown more evenly and over a wider area to the internal heat-generating components, improving the efficiency and coverage of air cooling. At the same time, the vortex generated by the airflow makes it difficult for small impurities to adhere to the inside of the rotating seat body, further reducing the residue of small impurities and reducing the impact of small impurities on heat dissipation.

[0018] 3. This device is equipped with a heat absorption mechanism. The outer shell is directly attached to the outside of the rotating shaft inside the rotating base body, and the bottom is tightly attached to the top of the motor. It can absorb the high heat generated by the motor operation in the first time. The phase change material filled on the back of the outer shell has heat storage capacity. It can absorb and store a large amount of heat through the latent heat of phase change when the motor is running under high load. At the same time, the multiple first fins fixedly connected to the side of the outer shell greatly increase the heat dissipation surface area, so that the heat that cannot be absorbed in time can be quickly dissipated through the airflow introduced by the fan, which plays a role in temperature control and buffering.

[0019] 4. This device is equipped with a servo mechanism. The cylinder is wrapped with phase change material of the heat absorption mechanism. When the solid paraffin inside melts at an increased temperature, it expands in volume, thereby pushing the piston plate and L-shaped piston rod to move. The first push rod pulls multiple baffles to deflect and open, realizing the function of opening windows for ventilation when the temperature rises. When the temperature drops, the baffles can be automatically reset and closed under the action of the return spring. This not only improves the heat dissipation efficiency, but also closes the air inlet in time to reduce the entry of fine impurities. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to embodiments.

[0031] See Figures 1 to 7 This embodiment provides a fixed rotating base for processing humanoid robot arms, including a rotating base body 10. The rotating base body 10 has a shielding mechanism 20 on its side for reducing the entry of external impurities. The shielding mechanism 20 has a deflection mechanism 30 inside for changing the airflow direction. The rotating base body 10 has a heat absorption mechanism 40 inside, and the heat absorption mechanism 40 has a servo mechanism 50 inside for driving the shielding mechanism 20.

[0032] See Figure 1 , Figure 2 , Figure 5 and Figure 7The shielding mechanism 20 includes an air inlet 201 and an air outlet 202 symmetrically arranged on the side of the rotating seat body 10. A rectangular frame 213 is fixedly connected to the air inlet 201, and a filter screen is fixedly connected to the air outlet 202. A fan 203 for blowing air into the rotating seat body 10 is fixedly connected inside the rectangular frame 213. A plurality of first rotating shafts 204 are also equidistantly rotatably connected inside the rectangular frame 213, and the first rotating shafts 204 are arranged horizontally inside the rectangular frame 213. A baffle 205 is fixedly connected to the outside of each first rotating shaft 204, and adjacent baffles 205 overlap each other.

[0033] One end of each of the first rotating shafts 204 extends outside the rectangular frame 213. A first lever 206 is fixedly connected to the extended end of the first rotating shaft 204. A first groove 207 is provided at the end of each first lever 206 away from the first rotating shaft 204. A first slider 208 is slidably connected inside the first groove 207. A connecting rod 209 is fixedly connected to the same end of multiple first sliders 208.

[0034] The connecting rod 209 is fixedly connected to the side of the first push rod 210, which extends into the interior of the rotating seat body 10 and is slidably connected to the rotating seat body 10.

[0035] The rectangular frame 213 is symmetrically fixedly connected to the outside of the fixed blocks 211, and the fixed blocks 211 are fixedly connected to the sliding rods 212. The sliding rods 212 are slidably connected to the two ends of the first push rod 210.

[0036] In specific operation, when the servo mechanism 50 is triggered due to temperature rise, it will push the first push rod 210 forward. The first push rod 210 slides inside the rotating seat body 10 and slides along the guide rod 212 fixed to the outside of the rectangular frame 213 by the fixed block 211, thereby driving the connecting rod 209 to move synchronously. The connecting rod 209 slides in the first groove 207 at the end of the multiple first sliders 208 fixedly connected to it, converting the linear translation of the connecting rod 209 into the rotation of the first slider 206. The first slider 206 drives the corresponding horizontally arranged first rotating shaft 204 to rotate inside the rectangular frame 213, causing the multiple baffles 205 fixed outside the first rotating shaft 204 to overcome the original overlapping state and deflect. The multiple baffles 205 open. At the same time as the baffles 205 open, the fan 203 fixedly connected inside the rectangular frame 213 forces cold air into the rotating seat body 10.

[0037] When the internal temperature of the rotating base body 10 decreases, the second limiting block 507 and the first push rod 210 are pushed to move in the opposite direction by the elastic force of the return spring 506. Through the above-mentioned reverse transmission structure, the adjacent baffles 205 are stacked on top of each other again, completely sealing the air inlet 201. When the robot is not in use or is not generating heat, the adjacent baffles 205 stack on top of each other to achieve physical sealing, which makes up for the shortcomings of traditional filters that cannot block fine dust, prevents fine dust and impurities from entering the interior of the rotating base body 10, and avoids the decline in heat dissipation performance caused by long-term accumulation of impurities.

[0038] See Figure 1 , Figure 2 , Figure 3 and Figure 5 The deflection mechanism 30 includes a second rotating shaft 301 symmetrically connected to the inside of the rectangular frame 213, and the second rotating shaft 301 is vertically arranged inside the rectangular frame 213. Each second rotating shaft 301 is fixedly connected to a partition 302 on the outside, and each partition 302 has a plurality of ventilation holes 303 on its surface.

[0039] Each of the second rotating shafts 301 is externally fixedly connected to a second lever 304. The end of the second lever 304 away from the second rotating shaft 301 is provided with a second groove 305. A second slider 306 is slidably connected inside the second groove 305. A crossbar 307 is fixedly connected to the top of the two second sliders 306. A second push rod 308 is fixedly connected to the side of the crossbar 307.

[0040] A support frame 309 is fixedly connected to the side of the rectangular frame 213 near the interior of the rotating seat body 10. The bottom of the support frame 309 is slidably connected to the second push rod 308. A roller 312 is rotatably connected to the end of the second push rod 308 away from the crossbar 307. A protrusion 313 is fixedly connected to the outside of the rotating shaft inside the rotating seat body 10. The protrusion 313 is rotatably connected to the roller 312. A first limiting block 310 is fixedly connected to the top of the second push rod 308. A W-shaped elastic sheet 311 is fixedly connected to the side of the first limiting block 310. The other end of the elastic sheet 311 is fixedly connected to the side of the rectangular frame 213.

[0041] In actual operation, when the robot is running, the rotating shaft inside the rotating base body 10 rotates synchronously, driving the protrusion 313 fixed to the outside of the rotating shaft to rotate together. The rotating protrusion 313 periodically contacts and pushes the roller 312 rotatably connected to the end of the second push rod 308. The second push rod 308 slides at the bottom of the support frame 309 fixed inside the rectangular frame 213. When the protrusion 313 pushes, the second push rod 308 moves forward and compresses the W-shaped elastic piece 311 fixed to the side of the first limit block 310. When the protrusion 313 passes the peak, the W-shaped elastic piece 311 releases its elastic potential energy and resets. Thus, the second push rod 308 forms a continuous reciprocating linear motion, driving the horizontal bar 307 at its top to move back and forth. The horizontal bar 307 slides within the second grooves 305 at the ends of the two second levers 304 via two second sliders 306, thereby driving the two vertically arranged second rotating shafts 301 to reciprocate. The second rotating shafts 301 drive the externally fixed partition 302 to reciprocate around the axis within the rectangular frame 213. When the airflow blown in by the fan 203 passes through the multiple vents 303 on the surface of the partition 302, the airflow direction continuously deflects as the partition 302 swings. The swinging of the partition 302 causes the direction of the cold air to change continuously, enabling the cold air to be blown more evenly and over a wider area to the internal heat-generating components, improving the efficiency and coverage of air cooling. The deflected airflow generates vortices inside the rotating seat body 10, making it difficult for small impurities to adhere and remain in the internal dead corners, further reducing the impact of small impurities on heat dissipation.

[0042] See Figure 1 , Figure 2 and Figure 5 The heat absorption mechanism 40 includes a housing 401 that is attached to the outside of the rotating shaft inside the rotating seat body 10, and the bottom of the housing 401 is attached to the top of the motor inside the rotating seat body 10. The back of the housing 401 is filled with phase change material 403, and a plurality of first fins 402 are fixedly connected to the side of the housing 401.

[0043] In actual operation, the outer shell 401, which is in contact with the outside of the rotating shaft inside the rotating base body 10 and whose bottom is tightly fitted to the top of the internal drive motor, directly absorbs the heat directly through heat conduction when the motor generates high heat under high load. When the motor generates excessive heat and produces instantaneous high heat, the phase change material 403 filled on the back of the outer shell 401 absorbs and stores a large amount of this heat through the principle of latent heat of phase change, playing a role in temperature control and heat buffering. Heat that cannot be absorbed or converted immediately is conducted away through multiple first fins 402 fixedly connected to the side of the outer shell 401. The multiple first fins 402 increase the heat dissipation surface area, and under the blowing of the cool air introduced by the fan 203, the heat is quickly dissipated into the air and discharged from the air outlet 202. The tight fit design combined with the heat storage capacity of the phase change material 403 addresses the severe heat generation caused by the drive motor driving the entire robot to rotate and the output shaft being subjected to large stress, providing a temperature control buffer. At the same time, the first fins 402 expand the heat exchange area, and together with the deflected airflow, maximize the overall thermal convection efficiency.

[0044] See Figure 1 , Figure 3 , Figure 5 and Figure 6 The servo mechanism 50 includes a cylinder 501 fixedly connected inside the housing 401 and extending outside the housing 401. The cylinder 501 is wrapped with a phase change material 403. A second fin 505 is fixedly connected to the outside of the cylinder 501. A piston plate 504 is slidably connected in the cavity inside the cylinder 501. Solid paraffin wax 503 is filled between the piston plate 504 and the bottom of the cylinder 501. An L-shaped piston rod 502 is fixedly connected to the side of the piston plate 504 away from the paraffin wax 503. The end of the L-shaped piston rod 502 away from the piston plate 504 is fixedly connected to the end of the first push rod 210 away from the connecting rod 209.

[0045] The servo mechanism 50 further includes a second limiting block 507 fixedly connected to the outside of the first push rod 210, and the second limiting block 507 is located inside the rotary seat body 10. A reset spring 506 for pushing the L-shaped piston rod 502 to move into the cylinder 501 is fixedly connected to the side of the second limiting block 507. One end of the reset spring 506 away from the second limiting block 507 is fixedly connected to the inner wall of the rotary seat body 10.

[0046] In operation, the cylinder 501 is tightly wrapped by the phase change material 403 in the heat absorption mechanism 40, and a second fin 505 is fixedly connected to its exterior. This fin transfers the temperature absorbed by the heat absorption mechanism 40 to the internal cavity of the cylinder 501. When the temperature rises to a set point, the solid paraffin 503 filling the bottom cavity of the cylinder 501 melts and expands in volume. The expanded paraffin 503 forcefully pushes the piston plate 504 and the L-shaped piston rod 502 fixedly connected to it upwards within the internal cavity of the cylinder 501. The protruding end of the L-shaped piston rod 502 is fixedly connected to the first push rod 210 of the blocking mechanism 20. The displacement of the L-shaped piston rod 502 pushes the first push rod 210 forward, overcoming the resistance of the return spring 506, ultimately achieving the action of opening the baffle 205 in conjunction with the phase change temperature of the phase change material 403, which is set to T1, and the melting point of the paraffin 503 is set to T2, satisfying T1≥T2+10℃. When the motor inside the rotating seat heats up, the heat is first transferred to the paraffin 503 through the second fin 505 with a high thermal conductivity, causing it to reach the melting point T2 and undergo volume expansion, triggering the mechanical window opening; if the temperature continues to rise to the extreme high load state, the heat is then absorbed by the phase change material 403 at the temperature T1 to achieve stepped thermal protection.

[0047] When the internal temperature of the rotating seat body 10 decreases, the paraffin 503 inside the cylinder 501 cools, condenses, and contracts. At this time, the previously compressed return spring 506 releases its elasticity, pushing the second limiting block 507 fixed outside the first push rod 210. The return spring 506 then pushes the first push rod 210 in the opposite direction, pressing the L-shaped piston rod 502 and piston plate 504 back into the cylinder 501. Simultaneously, the linkage shielding mechanism 20 automatically resets and closes the baffle 205. The entire process utilizes the physical properties of the phase change expansion of paraffin 503 as a power source, eliminating the need for additional complex electronic sensors or electric actuators, thus reducing energy consumption and maintenance costs and improving system reliability. It also achieves the effect of timely opening of the window for heat dissipation when hot and timely closing of the window for dust prevention when cold.

[0048] Working principle: When the humanoid robot arm generates heat from its internal motors during machining operations, the heat absorption mechanism 40 is activated first. The outer shell 401, which is attached to the outside of the rotating shaft and the top of the motor, absorbs the high heat immediately, and the phase change material 403 on its back provides heat storage and temperature control buffering. As heat continues to accumulate and the internal temperature rises, the adjacent servo mechanism 50 is then triggered. The solid paraffin 503 inside the cylinder 501 melts and expands, forcefully pushing the piston plate 504 and the L-shaped piston rod 502 to move. The displacement then pulls the first push rod 210, which in turn drives the mechanical drive shielding mechanism 20, causing the multi-level horizontally arranged and originally stacked baffles 205 to deflect and open. At the same time, the fan 203 inside the rectangular frame 213 begins to blow air inward for forced air cooling. When the cold air blown in by the fan 203 enters the rotating seat, the second push rod 308 of the deflection mechanism 30 drives the vertical partition 302 to swing back and forth, causing the airflow direction to be deflected when passing through the vent 303, ultimately achieving large-scale and uniform vortex convection heat dissipation.
