A spraying robot

Abstract

The invention provides a spraying robot, comprising a spraying robot body and a spray gun arranged on the spraying robot body, a motor wire wiring cavity is arranged on the spraying robot body, the motor wire and the motor are packaged in the motor wire routing cavity, and the motor The wire routing cavity is a closed cavity, and the spraying pipe is arranged outside the motor wire routing cavity. By encapsulating the motor wires and the motor in the airtight motor wire routing cavity, and setting the spraying tube outside the motor wire routing cavity, the motor wires and the motor are completely isolated from the spraying tube, even during the operation of the spraying robot If the spraying tube is broken, the spraying material such as paint will not touch the motor and motor wires, which greatly reduces the possibility of explosions and fires, ensures the safety of personnel and equipment to the greatest extent, and improves safety performance and reliability. sex.

Description

technical field [0001] The invention belongs to the field of automatic spraying, in particular to a spraying robot. Background technique [0002] In the spraying industry, in order to facilitate automatic control and reduce the impact on operators, spraying robots are generally used for spraying operations. Specifically, a spray gun is arranged at the end of the automatically controlled spray manipulator, and then the spray material is led to the spray gun through a spray tube. [0003] In the prior art, the wiring method of the motor line and the spraying tube of the spraying robot is generally adopted to enter from the base of the spraying robot, pass through the waist seat and the big arm, and then reach the three-axis box, and then the spraying tube reaches the mechanical wrist and the mechanical arm through the forearm. The spray gun is connected, so as to realize the connection of the motor line, the spray pipe and the motor or spray gun of the spraying robot. In thi...

Problems solved by technology

[0004] However, when the spraying robot performs spraying operations, it is applied in a mixed environment of flammable and explosive dangerous gases (gas generated by atomization during the spraying process of the spray gun). According to the national standard "GB3836 Electrical Equipment for Explosive Gas Environments", any use Electrical equipment in explosive gas atmospheres must be explosion-proof

In the above scheme, the motor line, motor and spraying pipe are located in the same cavity, which is extremely dangerous; once the spraying robot is in use, the spraying pipe breaks (the continuous rotation of each joint during the use of the spraying robot causes the spraying pipe to repeatedly rotate. bending, torsion, this situation is easy to happen) and touch the motor wire or motor in the same cavity, it is easy to cause explosion and fire, damage the spraying robot and other equipment and seriously affect the personal safety of the staff
