Working Principle of Welding Robot

Welding manipulators are intelligent equipment for welding operations. They are recognized by domestic companies and are widely used. Under this development trend, there are more and more manufacturers of welding robots. Among the many brands, welding robots are different. It's also very big. Do you know the working principle of the welding robot? Let's take a look at the following specific introduction.

Working principle of welding robot:

The welding robot is guided by the user to operate the robot step by step according to the actual task. The robot automatically remembers the position, posture, motion parameters, welding parameters, etc. of each action taught during the guidance process, and automatically generates a continuous execution of all operations program.

The above is a detailed introduction to the working principle of the welding robot. I hope it will be helpful to everyone. The welding robot performs electric welding operations in accordance with the actions, sequences, and parameters specified by the teaching program. The process is fully automated, with low energy consumption and high speed. , The advantages of simple maintenance and high precision, etc., are highly concerned by domestic enterprises.

So how to choose a welding manipulator? The following briefly introduces several issues that must be paid attention to in the selection of welding manipulators:

1) Workspace The actual workspace that the spot welding robot can reach is larger than the workspace required for welding. The working space required for welding is determined by the location of the solder joints and the number of solder joints.

2) Spot welding speed and production line speed must match. Firstly, the single-point working time is determined by the speed of the production line and the number of points to be welded, and the single-point welding time of the robot (including pressure, power, maintenance, displacement, etc.) must be less than this value, that is, the spot welding speed should be greater than or equal to the production line speed.

3) Selection of welding tongs Choose welding tongs according to the shape, type, and position of the weld. Choose C-shaped welding tongs for vertical and nearly vertical welding seams, and K-shaped welding tongs for horizontal and horizontally inclined welding seams.

4) When multiple robots are needed for model selection, it is necessary to study whether to use multiple models and use them with multi-spot welding machines and simple Cartesian robots. When the robot interval is small, attention should be paid to the arrangement of the action sequence, and interference can be avoided through robot group control or mutual interlocking.

5) Other spot welding robots with large memory capacity, complete teaching functions, and high control accuracy should be selected.

After taking the above points into consideration, the demonstration will be carried out from the aspects of economic and social benefits, and then it will be decided to use robots and the number and types of robots required.

Welding Manipulators

Welding manipulator China is a highly automated welding equipment. The use of robots to replace manual welding operations is the development trend of the welding manufacturing industry and is an important means to improve welding quality, reduce costs, and improve the working environment. As an important symbol of the development of modern manufacturing technology, robotic welding has been accepted by many domestic factories, and more and more companies prefer welding robots as a technological transformation plan.

The use of robots for welding, a robot is not enough, it must be equipped with peripheral equipment. The conventional arc welding robot system consists of 5 parts.

1. The robot body is generally a 6-axis articulated manipulator driven by a servo motor, which consists of a driver, a transmission mechanism, a mechanical arm, joints, and internal sensors. Its task is to accurately guarantee the position, posture, and motion trajectory required by the end of the manipulator (the gun).

2. The robot control cabinet, which is the nerve center of the robot system, includes computer hardware, software, and some special circuits, and is responsible for processing all information and controlling all actions of the robot during its work.

3. Welding power supply system, including welding power supply, special welding gun, etc.

4. Welding sensors and system safety protection facilities.

5. Welding fixtures.

For products with small batches, multiple varieties, larger volumes, or larger quality, a simple welding robot workstation or a robot workstation combined with a welding positioner and a robot can be used according to the spatial distribution of the welds of the workpiece. It is suitable for flexible production of "multi-variety, small-batch". The workpieces are small in size and easy to transport. And products with large quantities and many varieties and specifications. The welding process is subdivided, using a production line combining robots and special welding machines, combined with modular welding fixtures and rapid die change technology to achieve the goal of low investment, high efficiency and low-cost automation.
