Danger
Danger!
Most robot accidents are as follows:
1
、
The automatic operation was performed without confirming whether there is
anyone in the robot's motion range.
2
、
It enters the robot's motion range in the automatic operation state, and the robot
starts suddenly during the operation.
3
、
You just notice the robot in front of you, ignoring the others.
The above-mentioned accidents were all caused by the same reasons as "ignorance of safety operation
procedures" and "no idea that the robot would move suddenly". In other words, they are all accidents
caused by man-made unsafe behaviors such as "temporary negligence" and "failure to follow the prescribed
steps."
"Emergency situations" make it too late for operators to implement "emergency stop", "flee" and other
behaviors to avoid the accident, which may lead to major accidents. "Emergency situations" generally have
the following types.
1
)
Low-speed action suddenly becomes high-speed action.
2
)
Other operators performed the operation.
3
)
A different program was started due to an abnormality or program error in the peripheral equipment.
4
)
Abnormal operation due to noise, malfunction, defect, etc.
5
)
Misoperation.
6
)
Originally planned to regenerate at low speed to perform the action, but it performed the high-speed
action.
7
)
The work pieces transported by the robot fall and scatter.
8
)
When the work piece is in the stopped state of clamping and interlocking standby, it suddenly loses
control.
9
)
The next or behind robot performed the action.
The above are only some examples, and there are many forms of "emergency situations". In most
cases, it is impossible to "stop" or "escape" a robot that moves suddenly, so the following best
countermeasures should be implemented to avoid such accidents.
Danger
Be careful and approach the robot cautiously.
Danger
When the robot is not in use, measures such as "press the emergency stop button"
and "cut off the power" should be taken to prevent the robot from moving.
