2. Program overview
Welding system HY1006A-145 welding robot, welding power supply, robot special welding gun, cooling water tank, electrical control and other parts.
The workpiece is manually placed on the worktable to be welded, and the positioning and fixture clamping are completed, and the welding robot starts welding. After the welding is completed, the worker disassembles the workpiece, and then clamps the workpiece to be welded. Cycle in turn.


3. Process flow
The system welding workflow is as follows.
1) Welding workpieces are prepared according to the requirements of the drawings.
2) The operator places the work piece on the work to be welded, relies on the positioning block and the quick clamp to limit and press, and then press the start button.
3) The robot starts welding automatically from the set position. At this time, the worker goes to station two to clamp the workpiece.
4) When the robot finishes welding at station 1, and starts automatic welding at station 2, the operator arrives at station 1 to disassemble the welded product and continue to clamp the workpiece.
5) Cycle in turn.
4. Main functions
Welding: In order to ensure welding quality and welding efficiency, the robot system is equipped with a complete self-protection function and arc welding database.
Fault detection and prediction: After detecting the occurrence of an alarm, obtain data from the control device, guess the fault location and list the high fault locations in sequence, display the replacement sequence of parts, the computer and the diagnosis, and use iPendant to view it on the spot. In addition, the computer regularly obtains operating data from the robots on site, and analyzes the acquired data to determine whether the operating status of the robot is normal, and prompts the user to deal with upcoming failures.
Anti-collision function: When the robot welding torch collides with an external object, it can automatically fold back to protect the welding torch and the robot body.
Teaching programming: Realize on-site programming through the teach pendant configured by the robot.
Status display: The robot can display the operating status of the entire robot system through the teach pendant, including program operating status, welding process parameter changes, system parameter changes, robot current position, execution history, safety signals, alarm records, etc.
Users can know the status of the robot system in time, so as to prevent problems in the robot system in advance.
Input/output files: the system files and teaching program files in the robot system can be stored in the memory card inside the robot control cabinet, or extracted to external equipment, so that the customer can regularly back up the system files, once the robot system has problems You can restore system files to solve robot-related problems.


4. Features and advantages:

Using the most advanced servo technology, the robot moves fast, with high control accuracy and work efficiency
Digital communication is realized between the robot and the welding power source to ensure the high-speed coordinated control of the robot and the welding power source to achieve high-quality welding.
Provide carbon steel low-spatter, high-quality pulse and other welding methods, with a wide range of applications and strong welding capabilities.
Golden Red Eagle HY1006A-145 robot has open external communication and IO interface, which can be matched with mainstream welding machines at home and abroad.
It can be installed in all directions.


5.1 Robot Controller
The control of Huanyan HY1006A-145 cabinet robot control cabinet is based on our company's intelligent motion control system using industrial computer technology. The all-digital servo module provides driving power for the AC servo motors of the 6 joints of the robot.
It adopts a friendly and simple programming interface and icon-type buttons to make the operator easier to learn and comfortable. Distributed hardware structure and simplified instruction set software can ensure strict timing and task execution.

5.2 Color teaching pendant:
The robot system is equipped with a programmer with a large-screen color LCD display. The operation and programming are simple and clear. It has the functions of online welding parameter modification and fault self-diagnosis display. The display mode can be switched between Chinese and English, which is convenient for the operator. And a dead-man switch is installed to further ensure safety.
Through the clever design, the center of gravity of the teaching box is changed, the overall balance is improved, and the teaching and operation become easier.
The protection of the cable joints is strengthened by metal joints and plastic sheaths to avoid cable damage caused by pulling and scraping.
Menu operation, easy to learn and use.
Shortcut keys for switching additional axes and power indicator light, which simplifies the operation steps.
It is more convenient to exchange data with other devices, and data expansion is more convenient.
Have security protection settings.

5.3 Wire feeder
The wire feeder provided by our company is specially designed for robot welding system, which is small in size and light in weight.
 Stable wire feeding system
1. Fully digital wire feeding control, high-resolution speed feedback, high-precision speed adjustment
2. Double spring pressure arm adjustment, suitable for welding wire diameter of 0.8~1.6mm
3. The overall design is compact and lightweight, which maximizes the robot's motion performance

5.4 Special welding gun for robot
The robot welding torch uses our company's special robot welding torch. The company's welding torch has a long service life, significant cooling effect, and excellent mechanical fatigue resistance. This makes the MIG welding torch and related supporting equipment obtain a high cost performance. The field of robotics has been widely and rapidly applied.

5.5 Electrical control and button station
The electrical control system of the robot workstation uses the robot control cabinet I/O to control the equipment, including the start and stop of the robot, the welding power supply, the wire feeding mechanism and the control workstation.
