In industrial production, truss manipulators have been widely used in automated production lines due to their automation characteristics, precise positioning, and safety characteristics, which have improved the production efficiency and quality of enterprises. However, any mechanical equipment requires maintenance to extend its service life. So how can we extend the lifespan of the truss manipulator?
The maintenance and upkeep of the truss manipulator mainly includes general maintenance and routine maintenance.
General maintenance refers to the mechanical arm operator conducting a spot check on the equipment before starting it, confirming its integrity and the origin position of the mechanical arm; Pay attention to the operation of the robotic arm during the work process, including oil level, oil level, instrument pressure, indication signals, safety devices, etc; After use, clean and organize the work site, and clean the equipment.
Routine maintenance is divided into control cabinet maintenance and mechanical arm body system maintenance.
For the maintenance of the truss manipulator control cabinet, the maintenance interval mainly depends on the operating environment conditions, operating time, and temperature. Regularly check the heat dissipation of the controller to ensure that it is not covered by plastic or other materials, there is sufficient clearance around the controller, and it is away from heat sources. There are no debris piled up on the top of the controller, the cooling fan is working normally, and there is no blockage at the fan inlet and outlet. The cooler circuit is generally a maintenance free closed system, and various components of the external air circuit need to be regularly inspected and cleaned as required. When the environmental humidity is high, it is necessary to check whether the drainage outlet is regularly drained.
For the maintenance work of the truss manipulator body, the main tasks include surface cleaning and inspection of the machine equipment, lubrication of the reducer, and shaft brake testing of the manipulator.
① The truss robotic arm needs to be cleaned regularly and operated according to the instructions. High pressure cleaning equipment can be used, but direct spraying should be avoided, and attention should be paid to anti-corrosion and rust prevention; You can also use some solvents for wiping, but do not use highly corrosive solvents. The gaps at each connection should also be cleaned to avoid the accumulation of dust or particles, and can be wiped with a cloth that does not generate static electricity.
② Check the truss manipulator for corrosion, collision, detachment, oil leakage, water, electricity, and other phenomena. If such situations are found, promptly handle them. If they cannot be handled, consult technical personnel for professional maintenance. Do not blindly enter the truss manipulator operation area to repair equipment without authorization.
③ Check the connections of the truss manipulator for any looseness in the connectors and bolts, and tighten them in a timely manner if necessary. Especially, whether some braking and safety devices are flexible and reliable is a key inspection part in production safety, which needs to be paid attention to.
For the inspection of the braking device of the truss manipulator, the following methods can be used for testing:
Run the robotic arm to the corresponding position, where the total weight of the robotic arm and all loads reach the maximum value (maximum static load); Motor power outage; Check if all shafts are maintained in their original positions. If the mechanical arm still does not change position when the motor is powered off, then the braking torque is sufficient. You can also move the robotic arm to check if further protective measures are needed. When the truss manipulator comes to an emergency stop, the brake will assist in stopping, which may cause wear and tear. Therefore, repeated testing is required during the lifespan of the machine to verify whether it maintains its original capabilities.
