Application in force - controlled grinding control system

With the continuous development of industrial robot technology, the robot is no longer just a tool to carry heavy objects. The application of sensor technology makes the industrial robot a lot more intelligent. The sensor increases the sense of the robot and provides a foundation for the high-precision and intelligent work of the robot.

In the past, most of the domestic work pieces were deburring by hand, or by hand pneumatic, electric tools into grinding, grinding, filing and other ways to deburring processing, easy to lead to the increase of product defect rate, low efficiency, the processed product surface roughness and other problems. Traditional manual deburring has not been able to meet the needs of modern industrial production.

In recent years, more and more manufacturers began to use robots to install electric or pneumatic tools for automatic grinding. Robot industry deburring scheme generally has two forms, one is the robot loading machining spindle, the workpiece is fixed, the other is the robot grasping workpiece, the machining spindle is fixed, the two ways are compared to the current mainstream scheme.

Compared with handheld grinding, robot deburring can effectively improve the production efficiency, reduce costs, improve product yield, but because of mechanical arm rigid, other factors such as positioning error, the robot holding electric, pneumatic products deburring for irregular burr processing prone to cutting knife or damages to the workpiece, and so on and so forth. Moreover, the traditional casting cleaning technology adopts the principle of position control, so the robot running path needs to be determined as accurately as possible, and the programming work is complicated and time-consuming. Although the traditional technology can obtain the constant grinding and polishing quality theoretically, the fact is not satisfactory. The castings after processing often have different quality and different tolerances, so it is difficult to obtain the stable process effect.

When the robot is performing some tasks that have force action with the environment, such as grinding and assembling, the simple position control will cause excessive force due to position error, which will harm the parts or the robot. When a robot moves in such a motion restricted environment, combining ability control is often needed to use it.

Such as:

Application of force Sensors in industrial robotics Force and torque sensors:

The force torque sensor is a kind of sensor that can let the robot know the force. It can monitor the force on the robot arm, and provide guidance for the robot's next behavior according to the data analysis.

The biggest requirement of industrial robots, especially collaborative robots, is safety. To create a safe working environment, robots must be able to identify what is not safe. The use of a collision sensor allows the robot to understand what it is touching and send a signal to pause or stop the robot.

Application of force sensors in the field of industrial robots:

Unlike the collision detection sensor above, the use of safety sensors can allow industrial robots to sense the presence of objects around them, and the presence of safety sensors can prevent robots from colliding with other objects.

What are the applications of force sensors in the field of industrial robots?

Other sensors:

In addition to these there are many other sensors, such as welding seam tracking sensors, which you need to have in order to do a good job of welding, tactile sensors and so on. Sensors give industrial robots a variety of senses that help them become smarter and more accurate.

The force controlled polishing robot can achieve high efficiency and high quality automatic polishing, which is an effective solution to replace manual polishing.
