The most basic working principle of manipulator

by admin

The working principle and management of the manipulator, as well as its definition (or overview). Don’t perfunctory with those searched on Baidu. If I can find them, what else can I ask.

working principle of automatic packaging machinery

the level of automation has been continuously improved in the manufacturing industry, and the scope of application is expanding. In the packaging industry, automatic operation is changing the action mode of packaging process and the processing method of packaging containers and materials. The automatic control packaging system can greatly improve the production efficiency and product quality, significantly eliminate the errors caused by packaging process, printing and labeling, effectively reduce the labor intensity of employees and reduce the consumption of energy and resources
first, the role of automatic packaging

revolutionary automation is changing the manufacturing method of packaging and the transmission mode of products. The automatic control packaging system designed and installed plays a very obvious role in improving product quality and production efficiency, eliminating processing errors and reducing labor intensity. Especially for food, beverage, medicine, electronics and other industries, it is very important. The technology of automatic device and system engineering is further deepened and more widely used

robotics has changed the coexistence of man and machine. The key of automatic packaging is to design a structural scheme that can realize automatic control according to the production, processing or packaging process. Obviously, the choice of automatic device (manipulator or robot) depends on the needs and characteristics of this process. By definition, an automatic device is a machine or mechanism that can complete tasks through automatic control or remote control. It can be simple, for example, a pneumatic pressure linkage with single shaft structure moving from one position to another; It can also be complex, for example, a dynamic surgical robot with a six axis structure. The selection of various projects in the packaging process and various industrial automation institutions can enable each design scheme to complete a task within the space of a specific workplace

at present, the structural types of automatic devices are diverse. For example, it can meet the needs of a specific operation. The structural characteristics of industrial manipulators are between single axis and six axis. According to the performance of this shaft structure, the manipulator “arm” is designed to operate an end manipulator or arm end tool under the motion controllable program. The number of axes represents the “degrees of freedom” of the manipulator. In addition, there is an auxiliary arm. For example, the shaft of the conveyor belt, etc., but they are usually not mechanically connected with the main arm of the manipulator. For different types of manipulators, they are generally classified according to the coordinate system composed of three principal axes of “X”, “Y” and “Z”. Most machines belong to one of the following five basic types: Cartesian or rectangular coordinate system, cylindrical coordinate system, rotating or hinged coordinate system, spherical or polar coordinate system and flexible manipulator (SCARA)

a complete automation structure scheme consists of many components, among which the end arm operation tool, material conveying device and identification /verification system are the main components.

in terms of mechanical principle, the mechanical arm belongs to open chain transmission. I have done some exercises and returned them to the teacher
when I was in the Research Institute, I made a kind of manipulator similar to the one in your picture, which is a servo mechanism driven by hydraulic pressure. The stiffness is not solved well, and it vibrates when working. Those who want to engage in joint drive can’t solve the problem of harmonic reducer. It took about a year to dismantle it.
