Mechanical Operation and Maintenance Manual for ER20-1700 Industrial Robot

In order to comply with these principles, it is necessary to fully understand the following precautions
and follow them.
1.1.2 Safety Countermeasures for Robot Safety
Unnecessary protrusions or sharp parts should be removed in robot design.
Materials that suit the working environment and safety protective structures
against faults that are not prone to damage or accidents during movements should
be used. Additionally, safe operation should be ensured by installing misoperation
detection stop and emergency stop functions, and interlocking function to avoid
dangers when peripheral equipment acts abnormally.
The body is a multi-joint mechanical arm structure, and the angle of each joint
constantly changes during movement.
If it is necessary to approach the robot for teaching and other work, be careful not
to be clamped by joints. The end of each joint
’
s movement is equipped with a
mechanical stop, which is highly risky for being clamped. Therefore, special
attention should be paid to.
The arm may fall due to gravity or move to an uncertain direction if the servo
motor is removed or the break is released. Therefore, preventative measures must
be implemented and the surrounding safety conditions must be endured before
operation.
When installing attached machine on the end of the effector and the arm, strictly
follow the manual to use specified torque wrench to fasten screws of specified size
and quantity.
Do not use rusty or dirty screws.
Fastening screws in unspecified and improper ways could cause loosening, which
lead to serious accidents.
The end effector should be designed and manufactured within the allowable
payload range of the robot wrist.
Robot in operation should be stopped by emergency stop button at any time.
