The automation transformation of existing machine tools mainly adopts industrial robots to change the way workpieces are loaded and unloaded during the processing. Robots replace manual labor and special machines to complete workpiece loading and unloading, workpiece flipping, and process conversion. With little or no human intervention, mechanical parts processing units and production lines can achieve 24-hour large-volume automated processing.
I. Design Principles for Automated Retrofitting System of Machine Tool Loading and Unloading Robots:
Because renovation projects are carried out under the existing conditions of the factory workshop, they are subject to many objective limitations compared to new projects. Therefore, the system design of the engineering project must be:
1. Personalized. Tailored to the actual needs of the factory, fully meeting the requirements of automated production and solving key problems.
2. Economic efficiency. Focusing on the cost-effectiveness of the project, while meeting the requirements of automated production, we will make the best use of existing resources, avoid extravagance, and minimize expenses to save on renovation costs.
3. Maximize. With the same amount of modification cost, make the greatest effort to improve the degree of automation and reduce or eliminate the use of manual labor, thereby increasing output.
II. Flexible solutions for machine tool automation retrofit projects:
Because the renovation project is being carried out under existing conditions, key issues must be addressed flexibly:
1. Selection of industrial robots. Based on the effective height of the workshop and the production cycle, select gantry (truss type) or articulated robots.
2. Layout of robots and machine tools: The machine tools and robots on the automation of processing units and production lines can be arranged in L-shape, ring, "品" shape, "一" shape, etc., depending on the workshop area and under the premise of improving the production cycle.
3. Simultaneous production and modification. The installation and debugging of the loading and unloading robots are carried out separately from the machine tools, ensuring that production and modification are not disrupted.
