What are the components of the Mig welding robot?

At present, the commonly used industrial Arc welding robot system is mainly composed of the following five parts.

  1. Industrial robot body. Generally, it is a 6-axis articulated robot driven by a servo motor, which consists of a driver, a transmission mechanism, a mechanical arm, a joint, and an internal sensor. Its task is to accurately ensure that the end of the manipulator (welding gun) reaches the position, attitude and motion trajectory required by the system.
  2. Industrial robot control cabinet. The control cabinet is the nerve center of the industrial robot system, including computer hardware, software and some special circuits. Its task is to process all the information in the working process of the industrial robot and control all its actions.
  3. Welding system. Including welding power source, special welding torch, gas storage pipeline or device, welding wire barrel, wire feeding mechanism, etc.
  4. Welding tooling. Including positioner or flip frame, welding platform, etc.
  5. Others. Welding sensors and system safety protection facilities.

How does the MIG welding robot work?

At present, welding robots mainly complete welding work through teaching programming. Teaching: It is the process of robot learning. The operator uses the teach pendant (or manual dragging) to operate the robot to perform certain actions, and the robot will memorize it in the form of a program, and the programming is completed step by step. The operator sets the key points of the welding seam trajectory and welding parameters in the teach pendant. The welding parameters mainly include welding current, welding voltage, welding speed, wire feeding speed, welding torch posture, swing amplitude, etc. The industrial welding robot can memorize the operator operation, and automatically generate a program that performs the operation continuously. The robot shows the operation again according to the actions recorded during the teaching and the parameter program set, and observes whether there is any deviation in the motion trajectory of the industrial welding robot. After confirmation, the trial welding operation is carried out. The operator adjusts the welding parameters according to the welding quality. After completing the teaching and verification, the industrial welding robot only needs to give a start command to perform precise welding. When starting the industrial welding robot, it must be carried out in accordance with the operation process to reduce the incidence of misoperation. Of course, if there is a misoperation, the intelligent welding system will perform emergency stop work to play a protective role.

Can MIG welding robots be equipped with vision sensors?

Our own welding robot system is developed by ourselves, so even if other software is installed, it is compatible with communication. Let me analyze how the welding robot works with sensors.

The intelligent welding robot system calibrates between the vision and the robot to establish the motion relationship with the robot. After the vision captures and locates the feature points, the obtained coordinate information is transmitted to the robot for welding.

The robot converts the image coordinates transmitted by the vision into mechanical coordinates, and sends it back to the vision. After the vision performs arithmetic processing, the welding point is sent to the robot, and the robot completes the welding.

What are the advantages of MIG welding robots for processing companies?

  1. Robot welding can improve production efficiency
    The welding robot has a short response time and quick action. The welding speed is 60-3000px/min, which is much higher than manual welding. The robot does not stop or rest during the operation. As long as the external water, electricity and other conditions are guaranteed, the robot can continue to work 24 hours a day, which not only improves the production efficiency of the enterprise, but also greatly saves labor costs.
  2. Robot welding can improve product quality
    During the welding process of the welding robot, as long as the welding parameters and motion trajectory are given, the robot will accurately repeat this action. The parameters such as welding current, voltage, welding speed and wire length play a decisive role in the welding result. When using robot welding, the welding parameters for each welding seam are constant, which reduces the requirements for workers’ operating skills, avoids manual welding from being affected by the external environment, and ensures stable welding and high product quality.
  3. Robot welding can reduce business costs
    The cost reduction of welding robots is mainly reflected in large-scale production. One robot can replace 2 to 4 industrial workers, depending on the specific situation of the company. Robots can continuously produce 24 hours a day. In addition, with the application of high-speed and high-efficiency welding technology, the cost of welding using robots is more obvious.
  4. Robot welding is easy to arrange production plans
    Due to the high repeatability of the robot, as long as the parameters are given, it will always act according to the instructions, so the robot welding product cycle is clear, and the product output is easy to control. The production rhythm of the robot is fixed, and the production plan can be accurately arranged to maximize the production efficiency and comprehensive utilization of resources of the enterprise.
  5. Robot welding can shorten the cycle of product modification and replacement
    Robot welding can realize the welding automation of small batch products, shorten the cycle of product modification and replacement, and reduce the corresponding equipment investment. The biggest difference between a robot and a special machine is that the program can be modified to adapt to the production of different workpieces. When the product is updated, it is only necessary to replace the corresponding tools of the product design, and the robot body does not need to make any changes, and the product or equipment can be updated by changing the corresponding program commands.
