Common sensors for welding robots

What are the several sensors of the welding robot?

Wuxi JiHoYen Industrial Automation Co., LTD

In the field of automatic welding, the sensor has played an important role, welding robot is equipped with multiple sensors, can real-time monitoring in the process of welding, sensor provides the necessary welding information, control system and operators can perform related operations according to the information, this reflects the correct automation and intelligent welding, small make up to give you introduce the welding robot sensor.

Welding robot sensor is divided into internal sensors and external sensors, internal sensors can monitor the operation of the robot body, abnormal situation will timely feedback to the control system, emergency stop work to protect the robot body from damaged, external sensors will monitor the welding quality problem, if welding defects, artificial handheld teacher will appear warning signal, the operator will make corrective measures.

Common sensors for welding robots:

1. Vision sensor: Vision sensor is equivalent to the eyes of the welding robot, the visual sensor is divided into two-dimensional and three-dimensional vision sensor can detect the motion state of the parts, the robot adjusts the motion posture according to the motion state of the parts; the three-dimensional vision sensor has laser scanner of different angles to detect objects and create three-dimensional images to analyze good movements.

2.Mechanical sensor: mechanical sensor mainly sense the strength of the end actuator, mechanical sensor in the end effector and the position between the fixture, at the end of the sensor assembly welding, mechanical sensor is certain strength monitoring, in case of too strong, a certain limits.

3.Weld tracking sensor: the welding robot has the function of automatic weld tracking, automatically detect and adjust the position of the welding torch during the welding process, so that the welding torch controls the position of the weld, improve the accuracy of welding, and effectively stabilize the welding quality.

In addition, the welding robot also has collision monitoring sensors, motion sensors, quality sensors, etc. These sensors escort the work of the welding robot, improve the welding speed while stabilizing the quality.
