6 Axis Laser Robot Welder

what is robot laser welding machine?

Laser welding industrial robots are an efficient, environmentally friendly and intelligent welding solution, widely used in fields such as automotive manufacturing, aerospace, furniture manufacturing and electronic product production. It uses laser as the heat source to achieve stable and high-quality welding, which improves the product qualification rate, reduces labor intensity and costs. At present, the market for laser welding robots is growing rapidly and is expected to continue to rise in the future.

 

 

 

 

Laser welding industrial robots play a significant role in many high-end manufacturing fields. Their main application areas include but are not limited to the following aspects:

1. Medical device manufacturing: Medical devices made of biocompatible materials such as stainless steel and titanium alloy can achieve pollution-free and high-quality bonding through laser welding, meeting the strict standards of the medical industry.
2. Energy industry: For instance, in the welding of pipes, plates and other key components in nuclear energy, solar energy and wind energy equipment, laser welding has a good depth-to-width ratio and a relatively small heat input, which is conducive to reducing welding stress and deformation.
3. Household appliances and kitchen and bathroom products: Assembly of thin plate products, such as internal structural components of refrigerators and washing machines, as well as stainless steel kitchenware, using laser welding to enhance product quality and aesthetic appearance.

1. Quality and Precision: Welding parameters and positioning are precisely controllable. The weld seams have strong consistency and extremely low defect rates, and the quality is traceable, meeting the quality control requirements of high-end manufacturing.
2. Efficiency and production capacity: The welding speed is 2 to 3 times that of manual operation, allowing for continuous 24-hour operation with a stable cycle, significantly reducing auxiliary time and greatly enhancing production capacity.
3. Cost advantage: It can replace 2 to 4 skilled welders in the long term, recover the initial investment within 1 to 2 years, reduce material waste and hidden labor costs, and has low maintenance costs.
4. Safety and Compliance: Isolate dangerous environments such as high temperatures and smoke and dust to eliminate the risk of work-related injuries. The supporting purification system meets environmental protection requirements and reduces the compliance costs for enterprises.
5. Flexible Adaptability: It can quickly switch between multiple types of workpieces, complete complex trajectory welding, and meet the market demand of "multiple varieties and small batches".
6. Labor shortage relief: Lower the skill requirements for operators, avoid being affected by the shortage of skilled workers and personnel turnover, and stabilize the production rhythm

1. Arc welding robots (the most widely used) : including gas metal arc welding (MIG/MAG) and tungsten inert gas welding (TIG) robots, they are suitable for long weld seam welding of steel structures, automotive parts, pressure vessels, etc.
2. Resistance welding robot (mainly spot welding) : The core is used for automotive body assembly. By applying pressure and current through electrodes, it achieves spot welding of thin plate parts, with a fast welding speed (single-point spot welding ≤0.5 seconds).
3. Laser welding robot: Utilizing laser as the heat source, it features narrow weld seams and a small heat-affected zone, making it suitable for high-precision welding of precision components such as aerospace parts and electronic components.
4. Other types: such as plasma welding and brazing robots, suitable for welding requirements of special materials (such as titanium alloys, aluminum alloys) or special structures.

6 axis robot arm

 

 

The 6-axis robotic arm is one of the most widely used core configurations in the field of industrial robots. It is named for having six independent rotating joints (axes). Its design inspiration comes from the movement mechanism of the human arm - achieving all-round control of "position + posture" through the coordination of multiple joints It is the core equipment for achieving "high precision, high flexibility and complex operations" in automated production. Through the linkage of six joints, it can complete rotation, translation and posture adjustment at any Angle in three-dimensional space. It can flexibly adapt to various demands ranging from simple repetitive operations to complex trajectory operations. It is widely used in manufacturing scenarios such as welding, assembly, handling, spraying, grinding and loading and unloading, and is also the core execution unit of equipment such as robot welding machines and automated assembly lines.

Robot welding machine equipment is the "precision cornerstone" and "efficiency guarantee" of automated welding. Its core value lies in transforming the workpiece into a stable operation state for the robot through "precise positioning + reliable clamping + posture adaptation", solving problems such as welding deformation, weld seam deviation, and poor batch consistency from the source. Whether it is the dedicated tooling for large-scale standardized production or the modular/adaptive tooling for multi-variety flexible production, they all need to be deeply matched with the robot welding machine and the characteristics of the workpiece in order to maximize the quality and efficiency advantages of automated welding.  

The core of maintaining welding robots lies mainly in preventive maintenance, with precise care carried out by module to ensure stable operation of the equipment, consistent welding quality, and reduce the cost of downtime due to faults.

1. Daily inspection: Before starting the machine every day, check whether all components of the equipment are normal, such as the cooling level and temperature of the laser, the lubrication condition of the mechanical arm, the cleanliness of the optical components, the wire feeding mechanism and the gas supply system, etc.

2. Regular maintenance:  Regularly replace the protective lens of the laser cutting head to keep it clean. Clean the mirrors and lenses of the optical system to prevent dust and stains from affecting the optical path. Lubricate and maintain the robotic arm to keep the joints flexible and free from obstruction. Check whether there is any wear or looseness at the connection points of cables and pipes.

3. Functional testing: Regularly verify the accuracy of the robot by using special tools or programs to verify the accuracy and repeat positioning accuracy of TCP (Tool Center Point) points.

4. Recording and Analysis: Record in detail the operation data and fault information of the equipment, and regularly analyze the performance curve of the equipment to predict potential problems and carry out maintenance in advance.

5. External environmental control: Keep the working environment clean and dry, and reasonably control temperature and humidity to avoid adverse effects of environmental factors on the equipment.

6. Regular maintenance plan: Develop and implement a regular preventive maintenance plan based on the maintenance manual provided by the manufacturer, including replacing consumables, checking the insulation of electrical circuits, and conducting major overhauls, etc.

By strictly implementing the above operation and maintenance points, the equipment failure rate can be significantly reduced, and the working efficiency and product quality of laser welding industrial robots can be improved.
