Protection case of safety mat in automobile manufacturing plant

Lorem ipsum dolor sit amet consectetur adipisicing elit.

Scenario:

A robot arm workstation in a certain automobile assembly line. Operators need to enter the area regularly to calibrate workpieces, which may cause the robot arm to start up and collide with the robot arm by mistake.

Solution:

01.

Laying safety carpet:

Lay a circular safety mat 1 meter outside the robot arm's operating radius. The carpet surface is made of wear-resistant and oil-proof rubber material, which is suitable for the factory environment.

02.

Linkage control system:

The safety mat is connected to the equipment emergency stop module. When a person steps on it, a signal is sent in real time, triggering the robot arm to stop running within 0.5 seconds.

The accident rate of mistaken entry into the protection area has dropped by 100%, and 3 potential mechanical injuries have been avoided throughout the year;
Operators can safely perform calibration tasks without stopping the entire line, and production efficiency has increased by 15%.
Case source: Comprehensive industrial robot protection practice.
