Description

Technical Field

[0001] This utility model relates to the field of robot accessory equipment technology, and in particular to an integrated robot motor drive module. Background Technology

[0002] The integrated robot motor drive module is a core component for achieving precise robot movement. It undertakes the dual tasks of power conversion and motion control, converting the input electrical energy into the power to drive the motor through power devices. At the same time, it precisely adjusts the speed, direction and torque of the motor according to the instructions of the control system to ensure the coordinated movement of the robot's joints and complete complex tasks.

[0003] The integrated robot motor drive module mainly includes a power conversion circuit, a control circuit, a detection circuit, and a protection circuit. The power conversion circuit is composed of power devices responsible for power conversion. The control circuit receives signals from the host computer and regulates the power devices through pulse width modulation technology. The detection circuit monitors parameters such as current, voltage, and temperature in real time. The protection circuit is activated in case of abnormal conditions to prevent module damage. During operation, the module adjusts its output according to control commands and simultaneously feeds back data through the detection circuit to form a closed-loop control, thereby achieving stable operation of the motor.

[0004] However, current integrated robot motor drive modules suffer from heat dissipation challenges. Due to their high integration and power density, traditional heat sinks are insufficient, leading to limited space, insufficient heat dissipation area, and difficulty in rapid heat dissipation. This results in severe localized overheating, affecting device performance and lifespan. In industrial environments with high levels of dust and particulate matter, filter clogging is frequent, allowing unfiltered air to enter the module and causing dust to adhere to the heat sink fins and circuit boards. This not only reduces heat dissipation efficiency but may also cause short circuits and other malfunctions, increasing maintenance costs and downtime, and severely restricting the continuous and stable operation of the robot. Therefore, an integrated robot motor drive module is proposed to address these issues. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3 This utility model provides an embodiment of an integrated robot motor drive module, including a module box 1. The module box 1 contains components such as a power conversion module, a power supply module, a communication module, and a detection module, all of which are existing technologies and are not improvements to this application, so they will not be described in detail here. A fan 23 is installed in the middle of the module box 1 to enhance air circulation inside the module and improve heat dissipation efficiency. A quick-release mechanism is installed in the middle of the module box 1. A protective shell 14 is rotatably connected to the outside of the module box 1 to protect the module wiring terminals. A baffle 16 is fixedly connected to the outside of the module box 1. A snap-fit ​​component is installed inside the baffle 16, and the protective shell 14 is fixed by the snap-fit ​​component. A fixing bolt 24 is installed in the middle of the module box 1 to press and fix the external wires.

[0036] The quick-release mechanism includes a sliding assembly and a ejector assembly. The sliding assembly includes a stop block 2, which is slidably connected to the middle of the module box 1. A lever block 3 is fixedly connected to the outside of the stop block 2. A groove 4 is provided on the outside of the module box 1, and the lever block 3 is slidably connected inside the groove 4 for easy operation. A spring 5 is installed inside the module box 1, with one end of the spring 5 installed on the outside of the stop block 2. A mounting groove 6 is provided in the middle of the module box 1, and a filter screen 7 is installed inside the mounting groove 6. In its natural state, the elastic force of the spring 5 keeps the stop block 2 in its initial position, limiting the filter screen 7. When the filter screen 7 needs to be replaced, the lever block 3 is moved along the groove 4. The slider moves the stop block 2 to slide and compresses the spring 5, releasing the stop block 2 from limiting the filter screen 7, allowing the filter screen 7 to be removed for replacement.

[0037] The ejection assembly includes a top block 8, which is slidably connected to the middle of the module box 1. A fixing rod 9 is fixedly connected to the bottom of the top block 8. A second spring 10 is installed inside the module box 1. One end of the second spring 10 is installed at the end of the fixing rod 9. The top block 8 is slidably connected inside the mounting groove 6. When the filter screen 7 is installed, the top block 8 is squeezed by the filter screen 7, and the second spring 10 is in a compressed state. When the stop block 2 releases the limit on the filter screen 7, the second spring 10, which is in a compressed state, releases its elastic force and pushes the top block 8 upward through the fixing rod 9. The top block 8 then pushes the filter screen 7 out of the mounting groove 6, realizing the quick disassembly of the filter screen 7.

[0038] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 A fixed shaft 11 is fixedly connected to the middle of the module box 1. A rotating block 12 is rotatably connected to the outer periphery of the fixed shaft 11. A protective shell 14 is fixedly connected to the outer side of the rotating block 12. The protective shell 14 rotates around the fixed shaft 11 via the rotating block 12. A torsion spring 13 is sleeved on the outer side of the rotating block 12. The two ends of the torsion spring 13 are respectively installed in the middle of the module box 1 and the protective shell 14. In a natural state, the elastic force of the torsion spring 13 makes the protective shell 14 tend to rotate and open.

[0039] The snap-fit ​​assembly includes a snap ring 15, which is fixedly connected to the outside of the protective shell 14. The rotating protective shell 14 drives the snap ring 15 to move. A snap-fit ​​groove 17 is provided on the outside of the baffle 16, and the snap ring 15 snaps into the groove 17 to snap and fix the protective shell 14, protecting the terminal block and reducing the influence of environmental dust and other impurities. A button 20 is slidably connected to the middle of the module box 1, and a locking block 18 is slidably connected to the end of the button 20. A spring 19 is installed inside the module box 1, and one end of the spring 19 is installed on the end of the locking block 18. Under the elastic force of spring 19, the locking block 18 engages with the retaining ring 15. Rotating the protective shell 14 causes the retaining ring 15 to enter the retaining groove 17. Under the action of spring 19, the locking block 18 resets and engages with the retaining ring 15, thus fixing the protective shell 14. The outer side of the button 20 is fixedly connected to the limiting block 21. The middle part of the module box 1 has a limiting groove 22. The limiting block 21 is slidably connected to the middle part of the limiting groove 22. The cooperation between the limiting block 21 and the limiting groove 22 plays a limiting and guiding role in the sliding of the button 20, preventing the button 20 from falling off.

[0040] Working principle: First, press the filter 7 into the mounting slot 6. The filter 7 pushes the top block 8 down and compresses the second spring 10. At the same time, the stop block 2 resets under the action of the first spring 5, limiting and fixing the filter 7. After a certain period of use, move the toggle block 3 to drive the stop block 2 to slide and compress the first spring 5, so that the stop block 2 releases the limitation on the filter 7. At this time, the fixing rod 9 pushes the top block 8 upward under the action of the second spring 10. The top block 8 then pushes the filter 7 out of the mounting slot 6, realizing the quick disassembly of the filter 7 and facilitating quick replacement. This reduces the impact of dust on the heat dissipation of the internal module and reduces robot downtime losses.

[0041] When it is necessary to connect or disconnect the robot, press button 20. Button 20 pushes the locking block 18 to compress spring 19, causing the locking block 18 to release from the locking ring 15. At this time, the protective shell 14 rotates and opens around the fixed shaft 11 under the action of torsion spring 13, which facilitates the wiring of the module terminals. After the wiring is completed, rotate the protective shell 14 to make the locking ring 15 enter the locking slot 17. The locking block 18 resets under the action of spring 19 and locks with the locking ring 15, thus fixing the protective shell 14, protecting the connecting wires, reducing the impact of dust and other impurities on the power connection, and ensuring the stable operation of the robot.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
