II. Components of the system
The welding robot laser seam tracking system consists of a laser welding head, a vision sensor, a processor, a controller, and a robot.
Laser welding head
The laser welding head is used to emit a laser beam to scan the welding seam. The laser beam is reflected by a beam reflector and then received by a photodiode to form a signal. The signal is processed by the processor and converted into a digital signal, which is then transmitted to the controller.
Vision sensor
The vision sensor is used to measure the position of the welding seam before the robot operation, and to continuously monitor the position of the welding seam during the operation. The data is then sent to the controller in real-time.
Processor
The processor is used to integrate the data from the laser welding head and the vision sensor, and send the data to the robot. The controller can also adjust and optimize the system based on the feedback information from the robot operation, so as to improve the welding quality and efficiency.
Controller
The controller is the core of the entire system, which integrates the data from the laser welding head and the vision sensor, and sends the data to the robot. The robot performs the welding operation based on the data sent by the controller. The controller can also adjust and optimize the system based on the feedback information from the robot operation, so as to improve the welding quality and efficiency.
Robot
The robot is used to perform the welding operation based on the data sent by the controller.
III. Working process
The working process of the welding robot laser seam tracking system includes seam detection, laser scanning, seam tracking, system control, and system stop.
Seam detection
The vision sensor is used to detect the welding seam and calculate the position information of the seam. The data is then sent to the processor.
Laser scanning
The laser welding head is used to emit a laser beam to scan the welding seam. During the scanning process, the laser beam passes through the beam reflector and is reflected to the photodiode to form a signal. The signal is processed by the processor, converted into a digital signal, and transmitted to the controller.
Seam tracking
The vision sensor continuously monitors the position of the welding seam and sends real-time data to the controller.
System control
The controller integrates the data from the laser welding head and the vision sensor, and sends the data to the robot. The robot performs the welding operation based on the data sent by the controller. The controller can also adjust and optimize the system based on the feedback information from the robot operation, so as to improve the welding quality and efficiency.
System stop
When the robot completes the welding task, the system will automatically stop. Before stopping, the system needs to be cleaned and maintained to ensure normal operation for the next use.
IV. Advantages and applications
The welding robot laser seam tracking system has the advantages of high precision, high efficiency, and high stability. This system can be used for welding different materials, such as metal, plastic, ceramic, etc. Moreover, this system can be applied in different fields, such as automotive, aerospace, electronics, machinery, etc., to achieve high-quality and high-efficiency welding operations.
In conclusion, the welding robotlaser seam tracking system is an advanced and efficient automatic welding system that utilizes laser and vision technology to improve welding quality and efficiency. With the integration of a laser welding head, vision sensor, processor, controller, and robot, the system can accurately detect, scan, and track welding seams in real-time, and perform the welding operation with high precision and stability.
