AI Technical Summary
Existing collaborative robots cannot effectively control the working range of their upper arm and forearm in flammable and explosive environments, posing a safety hazard.
A four-axis collaborative robot with positive pressure explosion-proof function was designed. It adopts a positive pressure system control box and air circuit system. The internal positive pressure is maintained by blowing air pipes, and the material picking and placing is controlled by pneumatic suction cups. The use of electrical appliances is reduced to improve safety.
It enables safe operation in flammable and explosive environments, ensures gas protection for the robot's internal circuitry, reduces the use of electrical appliances, and improves safety and reliability.
