Scientific principles
Hydraulic manipulator is using PASCAL's law. PASCAL's law is a law of hydrostatics that states that any point in an incompressible stationary fluid is increased in pressure by an external force. The pressure increment is transmitted to every point of the stationary fluid in the instantaneous time. According to PASCAL's law, if there are two pistons of the same size in a fluid system, the pressure on the two pistons must be equal. The pressure is equal to the applied pressure divided by the stressed area. Then, a small push will be applied on the small piston. The hydraulic mechanical arm controls the slide of no. 2 syringe by pushing and pulling no. 1 syringe, and then controls the opening and closing of the gripper through a set of mechanical structures.

It is in the early emergence of ancient robots based on the development, manipulator research began in the middle of the 20th century, with the development of computer and automation technology, especially since the first digital electronic computer came out in 1946, the computer has made amazing progress, to high speed, large capacity, low price direction. At the same time, the urgent need of mass production promotes the development of automation technology and lays a foundation for the development of robots. On the other hand, the research of nuclear energy technology requires some operating machinery to deal with radioactive materials instead of human beings. In this context, the United States developed the remote-controlled manipulator in 1947 and the mechanical master-slave manipulator in 1948.
Manipulator first began to be developed from the United States, the united control company of the United States in 1958 developed the first manipulator, its structure is; A rotating arm is installed on the machine body, and the workpiece grasping and releasing mechanism of the electromagnetic block is installed on the top. The control system is in the shape of demonstration. With the rapid development of computer and automatic control technology, agricultural machinery will enter a highly automated and intelligent period, the application of manipulator robot can improve labor productivity and product quality, improve working conditions, solve labor shortage and other problems.
Manipulator is mainly composed of three parts: actuator, drive mechanism and control system. The hand is a part used to hold the workpiece (or tool), which has various structural forms according to the shape, size, weight, material and operation requirements of the object being held, such as clamping type, holding type and adsorption type. Movement mechanism, which enables the hand to complete various rotation (swing), movement or compound movement to achieve the specified movement and change the position and posture of the object being held. Movement of the lifting mechanism, expansion, rotation and other independent motion, known as the degree of freedom manipulator. In order to grab objects at any position and orientation in space, there are six degrees of freedom. Degree of freedom is the key parameter of robot hand design. The more degree of freedom, the greater the flexibility of the manipulator, the wider the versatility, the more complex the structure. General special manipulator has 2 ~ 3 degrees of freedom. Control system is through the manipulator each degree of freedom of the motor control, to complete a specific action. At the same time, the feedback information from the sensor is received to form a stable closed-loop control. The core of the control system is usually composed of microcontroller or DSP microcontroller.
With the development of network skills, the manipulator networking operation is also the direction of future development. Industrial manipulator is a kind of high-tech automatic production equipment developed in recent decades. Industrial manipulator is an important branch of industrial robot. It can be programmed to complete various expected tasks, in the construction and performance of both the advantages of man and machine, especially reflects the intelligence and adaptability of man. The accuracy of manipulator operation and the ability to complete operations in various environments have broad development prospects in various fields of national economy.
Manipulator is a new device developed in the process of mechanization and automation. In the modern production process, manipulator is widely used in the automatic production line, the development and production of robots has become a high-tech neighborhood, the rapid development of a new technology, it promotes the development of manipulator, so that the manipulator can better realize the organic combination with mechanization and automation. Although manipulator is not as flexible as the human hand, but it has the ability to constantly repeat work and labor, do not know fatigue, not afraid of danger, the power of grabbing heavy objects than the characteristics of the human hand, therefore, manipulator has been a lot of departments, and more and more widely applied. China's plastic machinery has become one of the fastest growing machinery manufacturing industries, the annual demand is constantly increasing. The rapid development of China's plastic machinery industry mainly has the following two major factors: first, the demand for high-tech equipment brought about by the renewal of equipment and obsolete equipment; Second, the rapid development of domestic plastic processing industry, the demand for plastic machinery is strong.
