Hi, friend,
Have you ever heard
Laser accidental injury incident ↓
See this, you are not hair erect,
I want to check myself around quickly,
Is there a hidden laser killer?
So, how to stop the laser doing things?
From the operational experience of industry,
To the laser with a high-quality servo system,
Can solve the problem of laser inaccuracy.
Below, we will first understand
How is the servo system guaranteed?
Laser does not yaw, does not sweep?
In industry, laser commonly used technologies are
laser detectionandlaser processingTwo major technologies.
industrial robots as we know them,
Many will use laser detection.
For example, handling robots,
You need a laser ranging sensor
(Sensor that uses laser detection technology to detect distance values)
Act as its eyes,
To detect the material and its distance,
and the position of the surrounding obstacles.
Its moving track is as follows:

Xie Jianrong. Industrial robot offset function and servo-driven laser detection technology combined application [J]. electrical engineering and automation)
The laser ranging sensor is driven forward by a servo motor
The PLC obtains the robot moving distance according to the servo motor encoder value.
The offset value of the robot gripper to grasp the material is calculated by the detection data of the laser ranging sensor.
The offset value is then sent to the robot controller through communication, and the controller issues instructions to the servo drive.
After the servo motor receives the drive resolution command, it controls the robot to complete the corresponding material grabbing and handling.
From the point of view of the trajectory,
Laser Ranging Sensor in Industrial Robot
There is no chance of running around or sweeping around,
Most of the time it will
is strapped to a robotic gripper or servo motor,
Actuated by servo motor
Measurement of material distance and angle
And then it measures the results,
were also transmitted to the control system in time,
Finally, according to the measurement results by the servo system
Drive the robot to complete.
That is, every step of laser detection,
And every result it detects, all
After understanding the laser detection, we will understand
Laser processing with higher precision requirements.
Take the widely used laser cutting.
Laser cutting mainly uses laser light speed
Direct figurative processing of materials.
For example, fish cuts on wood
Or cut stainless steel into circles of consistent size
In the actual laser processing, engineers found that
Due to the uneven surface of the material and the thermal effect of deformation and other factors,
The thickness of the cutting surface is not fixed,
even problems such as cambered surfaces,
This affects the accuracy of laser cutting,
Finished products caused by burrs, flash, dislocation and other defects.
So, we see that currently on the market,
Is still a foreign servo brand
to perform high-precision laser cutting.
However, with the continuous iteration of domestic servo technology,
Many manufacturers have broken foreign technology monopoly,
Achieve precise positioning of laser cutting.
Taking ATS series servo as an example,
A full range of independent research and development of core algorithms,
With excellent drive performance, positioning accuracy and reliability,
and features such as faster speed and dynamic response,
Help laser cutting can according to the field conditions,
Adaptive adjustment parameters, jitter suppression, etc,
Achieve high precision laser cutting.

See here, did you find
In the industrial field, in order to pursue better quality finished products,
Laser inspection and laser processing
Will be in the control system and servo system.
under precise control, unbiased,
To achieve accurate shooting.
hand drawn
So, if you don't want to laser yaw,
On the one hand, improve the performance of the system and hardware,
On the other hand, we also need to improve our security awareness.
Learn from life,
When we encounter laser-related scenes,
Then it is necessary to ask the merchants,
Whether the system and equipment are updated,
At the same time, also want to tell the friends around,
Whether it's a concert or a variety show,
Try not to let the phone shoot at the laser.
