Service life of loading robot arm

1. Design and manufacture of the robotic arm itself

Material quality: The materials used in the key parts of the robot arm, such as the arm frame and joints, determine its basic strength and durability. High-quality steel has strong fatigue and corrosion resistance and can withstand frequent heavy-load operations; if the material quality is poor, it is easy to crack and deform during long-term use, greatly shortening its service life. ​

Reasonable design: Reasonable structural design can make the various parts of the robot arm bear force evenly when working. For example, the optimized arm structure design can reduce stress concentration points and avoid local excessive force damage. At the same time, precise power system matching ensures that the motor, hydraulic pump, etc. provide appropriate power and reduce component wear caused by insufficient or excessive power. ​

2. Use process factors

Workload: Long-term overload use is an important reason for shortening the life of the robotic arm. Overloading will cause the various components of the robotic arm to be subjected to pressure beyond the design limit, accelerate wear, and cause deformation or even breakage of structural parts. Frequent lifting of cargo that is close to or exceeds the rated load will greatly reduce the durability of the robotic arm.​

Degree of operation standardization: The operator's operating habits have a significant impact on the robotic arm. Sudden stops and starts, as well as rough operations, will bring impact loads to the robotic arm, damaging the transmission system, joints and other components. Standardized and smooth operation can reduce unnecessary wear and extend service life.​

3. Maintenance status

Timeliness of daily maintenance: If daily cleaning, lubrication and inspection are not done properly, dust and oil will easily accumulate on the surface of the robotic arm, accelerating the corrosion of components; insufficient lubrication will lead to increased friction between components and accelerated wear. Timely and effective daily maintenance can keep the robotic arm in good operating condition and prevent small problems from turning into major failures.​

Regular maintenance quality: It is very important to regularly overhaul the robot arm, replace parts, and debug the system. Perform flaw detection on key parts according to the prescribed period to detect potential cracks in time; regularly replace worn transmission parts and aged seals, etc., to ensure the stability of the robot arm's performance and maintain its normal service life. If regular maintenance is not carried out, hidden faults will continue to accumulate, seriously affecting the life of the robot arm. ​

Maintenance after special working conditions: After working in bad weather (such as heavy rain, strong wind) or special environment (such as high humidity, high corrosion), if targeted maintenance is not carried out in time, the robot arm is prone to erosion and damage. For example, when working in a seaside port, the salt carried by the sea breeze is easy to corrode the metal parts of the robot arm, which need to be cleaned and anti-corrosion treated in time, otherwise it will seriously affect the service life. ​
