Description

Technical Field

[0001] This utility model belongs to the field of robotic arm technology, and in particular relates to a robotic arm air-cooling device. Background Technology

[0002] Robotic arms are the most widely used automated mechanical devices in the field of robotics. They can be found in fields such as industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although they vary in form, they all have one thing in common: they can receive instructions and accurately position themselves at a point in three-dimensional or two-dimensional space to perform tasks.

[0003] The existing utility model with authorization announcement number CN205310257U discloses a robotic arm, in which at least one shaft drive uses a hollow rotary platform reducer, the hollow rotary platform reducer is fixed on the fixed arm of the shaft, and the rotating arm of the shaft is fixed on the rotating platform of the hollow rotary platform reducer.

[0004] By adopting the above technical solution, replacing the original expensive harmonic drive reducer or RV reducer with a hollow rotary platform reducer significantly reduces manufacturing costs. When installing the hollow rotary platform reducer on the robotic arm, since no intermediate connecting parts are needed, the fixed arm and rotating arm on the same axis can be directly connected to the reducer, making installation more convenient and the structure more compact. However, with the above technical solution, the robotic arm typically needs to repeat the same action at a high frequency to complete industrial processing requirements. During long-term operation, the robotic arm will generate a heat load, but current robotic arms do not have good heat dissipation capabilities, preventing the heat load from being effectively removed, which in turn affects the service life and working accuracy of the robotic arm.

[0005] To address this issue, we propose a robotic arm air-cooling device. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that robotic arms do not have good heat dissipation, which makes it impossible to effectively remove heat load, affecting the service life and working accuracy of the robotic arms. Therefore, this invention proposes a robotic arm air cooling device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A robotic arm air-cooling device includes a rotating base. A connecting shell is fixedly connected to the upper surface of the rotating base. A first arm shell is rotatably connected to the left side of the connecting shell, a second arm shell is rotatably connected to the right side of the first arm shell, and a mounting bracket is rotatably connected to the left side of the second arm shell. Two air inlet slots are provided on the front and back of the connecting shell. An exhaust fan is fixedly connected to the inner bottom wall of the connecting shell. An exhaust port is provided on the upper surface of the connecting shell. Filter screens are fixedly embedded on both sides of the first and second arm shells. Two fixed cylinders are provided inside the first and second arm shells. A rotating motor is provided inside each fixed cylinder. A fan blade is fixedly connected to the output end of each rotating motor. Several exhaust holes are provided on the outer surfaces of the first and second arm shells. Two dust covers are fixedly connected to the outer surfaces of the first and second arm shells, and each dust cover is located outside the exhaust holes.

[0009] Preferably, a fixing plate is fixedly connected to the bottom surface of the rotating seat, and a plurality of fixing holes are provided on the upper surface of the fixing plate.

[0010] Preferably, a mounting plate is fixedly connected to the back of the mounting bracket, and the back of the mounting plate has a plurality of mounting holes.

[0011] Preferably, the outer surface of the exhaust fan is fitted with a protective cover, and the bottom surface of the protective cover is fixedly connected to the inner bottom wall of the connecting shell.

[0012] Preferably, a dust cover is fixedly connected to the upper surface of the connecting shell, and the dust cover is disposed outside the exhaust port.

[0013] Preferably, each of the fixed cylinders has a positioning plate fixedly connected to its outer surface, and the outer surfaces of several positioning plates are respectively fixedly connected to the interior of the first arm shell and the inner wall of the second arm shell.

[0014] Preferably, each of the rotating motors has three stabilizing plates fixedly connected to its outer surface, and the outer surface of each stabilizing plate is fixedly connected to the inner wall of the fixed cylinder.

[0015] Preferably, a first servo motor is fixedly connected to the front of the connecting shell, and the output end of the first servo motor is connected to the input end of the rotating seat through gear meshing. A second servo motor is fixedly connected to the right side of the connecting shell, and the output end of the second servo motor passes through the connecting shell and is fixedly connected to the inner wall of the first arm shell. A third servo motor is fixedly connected to the left side of the first arm shell, and the output end of the third servo motor passes through the first arm shell and is fixedly connected to the inner wall of the second arm shell. A fourth servo motor is fixedly connected to the right side of the second arm shell, and the output end of the fourth servo motor passes through the second arm shell and is fixedly connected to the inner wall of the mounting bracket.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] By incorporating an exhaust fan, outside air is drawn into the connecting housing through the air inlet slot and then expelled through the exhaust port. This continuous airflow within the connecting housing effectively removes the heat load generated by the continuous operation of the robotic arm. Furthermore, the power provided by the rotating motor, in conjunction with the fixed cylinder, drives the fan blades to rotate, drawing outside air through a filter into the first and second arm housings. Finally, the air is expelled through the exhaust port and dust cover, further dissipating the heat generated by the robotic arm's continuous operation through air cooling. This ensures the robotic arm has excellent air cooling capabilities, effectively removing the heat load and guaranteeing its lifespan and operational accuracy. Attached Figure Description

[0027] Filter screens 9 are fixedly embedded on both sides of the first arm shell 3 and both sides of the second arm shell 4. Two fixed cylinders 10 are provided inside the first arm shell 3 and the second arm shell 4. A dust cover 18 is fixedly connected to the upper surface of the connecting shell 2. The dust cover 18 is located outside the exhaust port 8. The dust cover 18 can prevent excessive dust and impurities from entering the connecting shell 2 through the exhaust port 8 without affecting the exhaust of the exhaust port 8.

[0028] Each fixed cylinder 10 is equipped with a rotating motor 11 inside, and a fan blade 12 is fixedly connected to the output end of each rotating motor 11. Several exhaust holes 13 are opened on the outer surface of the first arm shell 3 and the outer surface of the second arm shell 4. A positioning plate 20 is fixedly connected to the outer surface of each fixed cylinder 10. The outer surfaces of several positioning plates 20 are respectively fixedly connected to the interior of the first arm shell 3 and the inner wall of the second arm shell 4. The positioning plates 20 can position the fixed cylinder 10 so that the fixed cylinder 10 can be stably fixed in the working position.

[0029] Two dust covers 27 are fixedly connected to the outer surface of the first arm shell 3 and the outer surface of the second arm shell 4. Each dust cover 27 is located outside the exhaust port 13. Three stabilizing plates 21 are fixedly connected to the outer surface of each rotating motor 11. The outer surface of each stabilizing plate 21 is fixedly connected to the inner wall of the fixed cylinder 10. The stabilizing plates 21 can improve the stability of the rotating motor 11, allowing the rotating motor 11 to smoothly drive the fan blade 12 to rotate.

[0030] A first servo motor 22 is fixedly connected to the front of the connecting shell 2. The output end of the first servo motor 22 is connected to the input end of the rotating base 1 via gear meshing. A second servo motor 23 is fixedly connected to the right side of the connecting shell 2. The output end of the second servo motor 23 passes through the connecting shell 2 and is fixedly connected to the inner wall of the first arm shell 3. A third servo motor 24 is fixedly connected to the left side of the first arm shell 3. The output end of the third servo motor 24 passes through the first arm shell 3 and is fixedly connected to the inner wall of the second arm shell 4. A fourth servo motor 25 is fixedly connected to the right side of the second arm shell 4. The output end of the fourth servo motor 25 passes through the second arm shell 4 and is fixedly connected to the inner wall of the second arm shell 4. The inner wall of the mounting frame 5 is fixedly connected. Through the power provided by the first servo motor 22 and the internal gear structure of the rotating seat 1, the connecting shell 2, the first arm shell 3, the second arm shell 4 and the mounting frame 5 can rotate horizontally. Through the power provided by the second servo motor 23 and the connecting shell 2, the first arm shell 3 can be driven to swing. Then, the power provided by the third servo motor 24 and the first arm shell 3 can be driven to swing. Finally, the power provided by the fourth servo motor 25 and the second arm shell 4 can be driven to swing. This allows the robotic arm to smoothly rotate horizontally and perform gripping work at different angles.

[0031] The working principle of this utility model is as follows: In use, firstly, the exhaust fan 7, rotating motor 11, first servo motor 22, second servo motor 23, third servo motor 24, and fourth servo motor 25 are connected to an external power supply and controller. Then, the device is fixed in the working position using the fixing plate 26 and fixing holes 14. Different robotic arm grippers or fixtures are fixed to the mounting frame 5 using the mounting plate 15 and mounting holes 16. At this time, the power provided by the first servo motor 22, in conjunction with the internal gear structure of the rotating seat 1, allows the connecting shell 2, first arm shell 3, second arm shell 4, and mounting frame 5 to rotate horizontally. The power provided by the second servo motor 23, in conjunction with the connecting shell 2, drives the first arm shell 3 to swing. Then, the power provided by the third servo motor 24, in conjunction with the first arm shell 3, drives the second arm shell 4 to swing. Finally, the power provided by the fourth servo motor 25, in conjunction with the second arm shell 4, drives the mounting frame 5 to swing, allowing the robotic arm to smoothly enter... The robotic arm performs horizontal rotation and gripping operations at different angles. When the robotic arm generates excessive heat load due to prolonged operation and requires heat dissipation, the airflow provided by the exhaust fan 7 draws outside air into the connecting shell 2 through the air intake slot 6, and then exhausts it outwards through the exhaust port 8 and dust cover 18. The continuous airflow inside the connecting shell 2 effectively removes the heat load generated by the continuous operation of the robotic arm. Then, the power provided by the rotating motor 11, in conjunction with the fixed cylinder 10 and the stabilizing plate 21, drives the fan blades 12 to rotate with the assistance of the positioning plate 20. This draws outside air into the first arm shell 3 and the second arm shell 4 after being filtered by the filter screen 9, and finally exhausts it outwards through the exhaust port 13 and dust cover 27. At this point, the heat generated by the continuous operation of the robotic arm can be further removed through air cooling, giving the robotic arm a good air cooling function, effectively removing the heat load generated by the robotic arm, and ensuring the service life and working accuracy of the robotic arm.
