Description

technical field [0001] The invention relates to a mechanical structure and control system of a pneumatic transport manipulator, which belongs to the field of pneumatic transport manipulators. It is a mechanical structure and control circuit of a pneumatic transport manipulator with accurate positioning and easy implementation, and is especially suitable for point transport of injection-molded blades in air conditioners. . Background technique [0002] Traditional manipulator applications mostly use electric servo drive, because electric servo technology has gone through a long period of development and has become a very mature technology (Yang Zhenqiu, Research and application of simple and precise positioning pneumatic manipulator[ D] Wuhan: Huazhong University of Science and Technology, 2006). The driving motor generally adopts stepping motor, AC and DC servo motor, etc. The manipulator with electric drive is characterized by large driving force, very high control precis...

Problems solved by technology

However, some workplaces only need to reciprocate the parts between two points. The positioning accuracy of the manipulator using the pneumatic servo system is high. Although it can complete related functions, the cost is relatively high.

If the mechanical arm of the pneumatic manipulator wants to achieve a certain angle of rotation, it needs to use a swing cylinder, and the positioning accuracy of the swing cylinder is generally not high, and it cannot perform high-precision positioning
