Description

Technical Field

The rigidity of the arm directly affects the smoothness of the arm's movement when grasping workpieces, the movement speed, and the positioning accuracy. However, the current robotic arms have the following problems:

[0041] A protection box 14 is provided on the other side of the upper end of the mounting plate 15, and a lifting mechanism is provided in the protection box 14. The lifting mechanism includes a second connecting block 24 and a first connecting block 20 installed in the protection box 14, and a third hydraulic cylinder 25 is installed at one end of the second connecting block 24. A movable plate 21 is fixed to the end of the piston rod of the third hydraulic cylinder 25, and four guide rods are fixed between the second connecting block 24 and the first connecting block 20.

The combination of hydraulic drive and motor drive has the following advantages:

[0044] 1. Combination of high torque and high precision

[0045] Hydraulic drive: provides high power density (up to 2.3kW / kg), suitable for large torque output above 2000N·m, meeting the needs of heavy workpiece handling.

[0046] Motor drive: Achieve ±0.005° positioning accuracy through the servo system, suitable for fine movements (such as assembly and welding.

[0047] Synergistic effect: The hydraulic system takes on the main driving force, and the motor performs fine-tuning compensation, which improves the overall accuracy by more than 3 times.

[0048] 2. Dynamic load adaptability

[0049] The hydraulic module can quickly respond to load changes (such as sudden impact force) and achieve dynamic output adjustment (±75% range) through pressure closed-loop control.

[0050] The motor system corrects the speed deviation in real time through current feedback, suppressing the vibration amplitude to 18% of the traditional system.

[0051] 3. Optimize energy efficiency and improve reliability, maximize energy utilization

[0052] Under light load conditions, it is mainly driven by electric motors, and the energy consumption is only 30% of that of hydraulic systems;

[0053] The hydraulic system is automatically activated when overloaded, and the power density is increased by 187% compared to a pure electric drive solution.

[0054] 4. Security

[0055] When the hydraulic system fails, the motor can take over part of the power (such as maintaining end positioning). When the motor fails, the hydraulic emergency brake response time is <10ms. The dual-system independent temperature control module (hydraulic oil ±0.5℃, motor winding ±1℃) can avoid thermal failure.

[0056] 5. Enhanced control and adaptability

[0057] The composite control strategy adopts a master-slave control architecture. The hydraulic system performs coarse positioning, and the motor achieves high-precision trajectory tracking (error <0.02mm). The CAN bus protocol is used to achieve dual-system data synchronization with a delay of <2ms.

[0058] 6. Breakthrough in environmental adaptability

[0059] The hydraulic system can work in extreme temperatures of -40℃-120℃ (the motor needs heating / cooling device to assist) 510, in dusty environment, the hydraulic sealing is better than the motor (IP68 protection vs IP54

[0060] The comprehensive cost of the present invention is reduced, energy consumption is reduced by 25% compared with a single system, maintenance cost is reduced by 40%, and the operating range is expanded to: 0.1-500kg workpieces can be processed simultaneously, the applicable scenarios are increased by 300%, and the safety level is improved: the dual system redundant design reduces the failure downtime rate to 0.001 times / thousand hours;

[0061] A second mounting block 31 is fixed to one side of the support arm 7, and a plurality of slots 32 are evenly spaced on one side of the second mounting block 31, and a plurality of mounting holes 33 are evenly spaced on the side wall of the slot 32 for stable mounting and fixing, and the number of hydraulic cylinders can be selected as needed;

[0062] Slide blocks 26 are fixed on both sides of the lower end of the mounting plate 15. Electric guide rails 3 corresponding to the slide blocks 26 are provided on both sides of the lower end of the mounting plate 15. A slide block 26 on the same side is installed on an electric guide rail 3 on the same side. The electric guide rail 3 can realize a preset path or track the dust diffusion trajectory (such as welding and cutting operation points) in real time, so that the dust collector is always in the best working position. Compared with a fixed dust collector, the dust capture rate is increased by 20%-30% (measured data), which is especially suitable for mobile pollution sources or dispersed operation scenarios. By dynamically adjusting the distance between the dust collector and the pollution source and maintaining the tangential speed in the cyclone (usually 15-25m / s), the centrifugal force is maximized to avoid the escape of edge airflow caused by the fixed position. The removal rate of particles above 5μm is stabilized at more than 99%.

[0063] In the present invention, a composite topological base structure is adopted, a carbon fiber and titanium alloy laminated structure (bending modulus ≥ 120GPa) is applied, and a honeycomb shock-absorbing cavity is built in (damping coefficient 0.35). Compared with the traditional casting base, the weight is reduced by 62%, and the resonance frequency is increased to 200Hz. The tensile strength of carbon fiber and the compressive performance of titanium honeycomb complement each other, which is 40% higher than the strength of a single material structure. The dynamic damping is optimized, and the honeycomb cavity is graded and buffered to improve the impact energy absorption rate. Through a detachable hydraulic drive mechanism (single cylinder output 50-500N adjustable), online hot-swappable configuration is supported, and the driving power can be dynamically adjusted by increasing or decreasing the number of hydraulic cylinders by ±75%. A centrifugal cyclone dust collector (filtration efficiency ≥ 99%) is arranged on one side of the robotic arm base, and an electrostatic adsorption filter (PM2.5 retention rate 95%) is used to filter out dust at a dust concentration of 100mg / m 3 Working continuously for 500 hours in an environment with a contamination level of key components less than 0.1mg / cm 2 .

[0064] In the present invention, through the coordination of hydraulic drive and motor drive, the hydraulic system assumes the main driving force, and the motor performs fine-tuning compensation, the comprehensive accuracy is improved by more than 3 times, and the motor is mainly driven under light load conditions, and the energy consumption is only 30% of the hydraulic system. When overloaded, the hydraulic system is automatically activated, and the power density is increased by 187% compared with the pure electric drive solution. When the hydraulic system fails, the motor can take over part of the power (such as maintaining end positioning). When the motor fails, the hydraulic emergency braking response time is <10ms, and the dual-system independent temperature control module (hydraulic oil ±0.5℃, motor winding ±1℃) can avoid thermal failure.
