Problems solved by technology

Secondly, since the automatic line and the robot face different work objects at different times and in different processes, the required vacuum degree and exhaust volume are also different. For example, the adsorption object is a material with good airtightness (glass, steel, etc.), it requires high vacuum degree and small displacement, and when the adsorption object is a material with poor airtightness (corrugated cardboard, etc.), it requires low vacuum degree and large displacement. Different intake pressures and different vacuum generators are required, which makes the gas supply system complex and inconvenient to use, and the pressure fluctuations between different pipelines in the pressure system will also cause interference.

Abstract

A combination evacuating generator comprises a first body and in which disposed a vacuum generation device. The vacuum generation device consists of a jet nozzle and expanding nozzle located in the same axis. The jet nozzle and the expanding nozzle are both heavy members and can be mounted in the first body. The combination vacuum generator also comprises a control valve located in the second body for controlling the intake pressure. Regulating the control valve make the vacuum generator be at the optimum state.

Description

(1) Technical field [0001] The invention relates to a combined vacuum generator, in particular to a modular reconfigurable combined vacuum generator with the function of adjusting and stabilizing the intake pressure. (2) Background technology [0002] At present, with the continuous improvement of the level of industrial automation, vacuum generators and vacuum suction cups have been widely used in automatic manufacturing production lines, assembly automatic lines, warehouse management and robots in the automobile manufacturing industry, household appliance manufacturing industry, glass manufacturing industry, plastic parts manufacturing industry and other industries. It has been widely used, such as washing machine assembly automatic line, stamping automatic line, automobile assembly automatic line and other automatic lines, a large number of vacuum generators and vacuum suction cups are used. Since automatic lines and robots require short beats and fast response speeds dur...
