Integrated control method for vacuum detection and filling of workpiece

Abstract

The invention provides an integrated control method for vacuum detection and filling of a workpiece, and the vacuum performance of the workpiece can be detected automatically; and the workpiece is filled. Automatic control over a process is achieved through a system according to a preset judgment value, and traditional manual control is changed into automatic control; on the premise of ensuring that a workpiece finished product reaches the standard, evacuated time is optimized through the system according to a vacuum value, and an evacuation valve and a filling valve are opened and closed automatically; a feedback mechanism is formed by valve status and operation status; efficient and accurate switching among working procedures is achieved, and the overall production efficiency is improved; manual intervention is not required; not only is the labor cost reduced, but also extra errors caused by artificial judgment are avoided; and the accuracy of detection results is improved effectively.

Description

technical field [0001] The invention relates to the field of vacuum perfusion, in particular to an integrated control method for workpiece vacuum detection and perfusion. Background technique [0002] In industrial production, one of the steps before pouring the container workpiece is to evacuate the container workpiece and detect the vacuum degree at the same time. When the vacuum degree reaches the preset value, it indicates that the workpiece production is qualified, and then enter the next pouring process. At present, the progress and switching process of the process is generally performed manually. The vacuum pipe joint is connected to the container workpiece, and the vacuum is continued for a period of time. The personnel monitor the vacuum value to determine whether the workpiece is qualified. When the vacuum value reaches the set threshold, It shows that the workpiece is produced qualified, then manually remove the vacuum pipe joint, connect the container workpiece w...

Problems solved by technology

[0003] At present, in all kinds of vacuum detection, vacuum perfusion and other systems with workpiece vacuum detection functions on the market, the detection standards and detection procedures of the workpiece vacuum degree are generally set by the manufacturer in advance according to the highest industry standards. It meets the needs of manufacturers for product vacuum testing, but because the testing procedures are set according to high standards, for some manufacturers who do not have such strict requirements on the vacuum degree of workpieces, the production efficiency of their products is limited. Not a small impact, and because the detection process is generally set before the system leaves the factory, the manufacturer often cannot change it by itself, and can only contact the corresponding supplier for after-sales technical support, and the operation is cumbersome
