Selecting an industrial robot is a complex task that involves considering a variety of factors. Here are some key considerations:
1. Application scenarios and requirements:
• Specify the production line in which the robot will be used, such as welding, assembly, handling, spraying, grinding, palletizing and other different application scenarios.
• Consider the properties, size, weight, and shape of the materials on the production line.
2. Load capacity:
• Select a robot based on the maximum weight of the materials to be handled or operated, ensuring that its payload capacity is sufficient to perform the task.
3. Scope of work:
• The size of the robot's workspace determines its reach, ensuring that the robot's reach can meet the needs of the work area.
4. Accuracy and repeatability:
• For tasks requiring high precision, such as precision assembly and welding, robots should have high positioning accuracy and repeatability.
5. Speed and beat time:
• Select robots based on the production line's cycle time requirements; faster robots can improve production efficiency.
6. Flexibility and programmability:
• Consider whether the robot supports flexible programming and can adapt to changes in production tasks.
7. Navigation Method:
• Select the appropriate navigation method based on the production line layout and process requirements, such as fixed path, free path, laser navigation, visual navigation, etc.
8. Control System and Software:
• Ensure that the robot control system can be smoothly integrated with the factory's existing production management system, ERP system, etc.
9. Safety and Protection:
• Robots should be equipped with appropriate safety protection devices, such as safety fences, light grids, and emergency stop devices, to ensure the safety of human-robot collaboration.
10. Maintenance and Service:
• Consider the robot manufacturer's after-sales service and technical support capabilities, as well as the availability of spare parts.
11. Investment Costs and Rates of Return:
• Calculate the input costs and expected benefits, including the purchase cost of the robot itself, installation and commissioning costs, and operation and maintenance costs. Only by comprehensively weighing all these factors can the most suitable industrial robot for the specific production line needs be selected.
Furthermore, with the development of technology, it is also necessary to pay attention to whether robots possess advanced characteristics such as intelligence, autonomous learning, and human-machine collaboration, so as to better adapt to future production environments.
The following principles should be followed when selecting industrial robots:
1. Applicability Principle: Select the robot type based on the specific process requirements of the production line, such as arc welding, spot welding, assembly, handling, gluing, cutting, polishing, packaging, etc. Ensure the robot can complete the designated production tasks.
2. Load and travel principle: Select the robot's load capacity according to the weight of the materials to be handled or operated, and select the robot's arm span and working radius according to the working range.
3. Precision and Speed Principles: For operations requiring high precision, such as precision assembly and electronic assembly, robots with high repeatability should be selected. Simultaneously, an appropriate movement speed should be chosen based on production cycle time and efficiency requirements.
4. Flexibility and scalability principle: Consider whether the robot has sufficient flexibility to adapt to changes in different products or production lines, and whether it supports subsequent upgrades and expansions.
5. Safety principle: Ensure that the robot has complete safety protection measures, such as safety fences, emergency stop devices, safety sensors, etc., and comply with relevant safety standards and regulations.
6. Integration and compatibility principle: Consider the compatibility and integration of the robot control system with existing production equipment, production line control systems, ERP/MES and other systems, and whether data sharing and real-time communication can be achieved.
7. Reliability and maintainability principles: Choose robot brands with good reputation, high reliability, long service life, convenient maintenance and repair, and sufficient spare parts supply.
8. Economic principle: Conduct a full life cycle cost analysis by combining factors such as initial investment cost, operating cost, expected service life, energy consumption, and maintenance costs to ensure a reasonable return on investment.
9. Technical Support and Service Principles: Examine the robot manufacturer's technical strength, service capabilities, and after-sales service commitments to ensure effective technical support during equipment installation, commissioning, maintenance, and upgrades.
In summary, the selection of industrial robots requires comprehensive consideration of multiple factors, including actual production needs, technical performance, economic benefits, safety and reliability, and post-maintenance, to ensure that the robots can effectively improve production efficiency, reduce costs, ensure production safety, and adapt to changes in future production models.
