Industrial manipulator is an automatic device structure is simple, in most cases by the cylinder to drive the motor in a few cases, mainly in the form of motion into linear motion, less degrees of freedom, is generally 2 - 3. Manipulator is widely used in various automatic machines and automated production lines, mainly for the transfer of various workpieces and products. According to the difference of load capacity, small and medium sized machine hand generally applied to the workpiece or the products transferred to smaller, lighter, and the large mechanicalhand, transferred to larger mass load. To sum up, there are approximately the following aspects.
Assembly is more manual work in the process of mechanical manufacturing, because of its technical complexity, it is difficult to automate, and labor productivity is low. It is only in recent years that industrial robots have been used in automatic assembly.
2. spray paint
Painting manipulator is one of the most widely used field of industrial manipulator. The utility model uses spray gun to directly spray paint on objects, and the paint is sprayed on the surface of the object by spraying nozzles. The painting environment is not conducive to the people to stay, because of lack of oxygen in the air spray, serious pollution, there are flammable and explosive hazards, although can improve the ventilation conditions, but is not easy to be improved fundamentally. As shown in the diagram, the painting manipulator can liberate people from the harsh environment, and paint quality is more uniform than people, save paint dosage, save production area and obtain higher productivity.
In the welding process, the industrial manipulator has long been widely used in automobile spot welding. The original manual spot welding has great labor intensity, and the quality of solder joints often decreases with people's fatigue. Figure 9.19 shows the automobile housing spot welding production line.
4. material transfer
For the production of equipment, workpiece handling of industrial manipulator, there are: only feeding operations, only laying down materials, and the completion of the completion of material delivery, unloading 3 jobs.
