Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum generators, and in particular relates to a compact integrated vacuum generator. Background Art

[0002] In the field of industrial automation, vacuum generators are a key component and their importance is self-evident. This type of equipment uses positive pressure gas sources to efficiently convert into negative pressure vacuum, greatly broadening its applicability in a variety of application scenarios such as machinery, electronics, packaging, printing, plastic processing and robotics. However, with the continuous advancement of industrial technology and the increasing complexity of automated production lines, existing vacuum generators have gradually revealed some limitations in design, performance and functional integration.

[0003] Many vacuum generators on the market today often sacrifice compactness in design to meet high-precision or specific functional requirements, resulting in a larger overall size. This design not only increases the difficulty of installation, but also limits its wide application in automated production lines with limited space. Especially in modern factories that pursue high integration and flexible layout, large-volume vacuum generators are difficult to meet the needs of flexible installation and rapid deployment.

[0004] In application scenarios that require high-flow vacuum, although traditional vacuum generators can provide sufficient vacuum flow, their destruction flow (i.e., the ability to quickly release vacuum) is relatively small, which affects the response speed of the equipment and overall work efficiency. This performance bottleneck is particularly obvious for applications that require rapid switching of vacuum states to complete complex movements. Although some integrated vacuum generators have reduced their size to a certain extent, they often do so at the expense of reducing vacuum flow and destruction flow, making it difficult to simultaneously meet the dual needs of high performance and small size.

[0005] Existing integrated vacuum generators have deficiencies in functional design. Most of them only integrate basic vacuum generation functions, but lack the integration of advanced functional modules such as solenoid valve control and digital display pressure gauges. These additional functions are of great significance for improving the automation level of equipment, simplifying operating procedures, and realizing remote monitoring and fault diagnosis. Therefore, the lack of functional integration limits the in-depth application of vacuum generators in high-end automated production lines.

[0006] To sum up, in view of the problems of existing vacuum generators in terms of volume, performance and functional integration, it is necessary to develop a new type of vacuum generator. The equipment should have the characteristics of small volume, large flow and efficient flow destruction, and integrate advanced functions such as solenoid valve control and digital display to meet the growing diversified needs in the field of industrial automation.
