The invention relates to a two-liquid screw valve capable of accurately monitoring flow, and belongs to the technical field of machinery. The invention provides a two-liquid screw valve capable of accurately monitoring the flow rate, which includes a first monitoring module for monitoring the input flow rate of glue, a second monitoring module for monitoring the mixed flow rate of glue, and a second monitoring module for monitoring the output flow rate of glue Three monitoring modules; the setting of the first monitoring module enables the double-liquid screw valve to independently monitor the input glue volume of the two kinds of glue to be mixed, and cooperate with the dynamic adjustment of the controller to ensure the best flow of glue input; the second monitoring module The setting of the double-liquid screw valve can independently monitor the output glue volume of the two kinds of glue to be mixed, monitor the ratio state of the two kinds of glue to be mixed at all times, and cooperate with the dynamic adjustment of the controller to ensure the best ratio of glue output. To achieve the best characteristics of the glue; the setting of the third monitoring module enables the double-liquid screw valve to monitor the glue output of the mixed glue at all times to ensure the best accuracy of the glue output.
Description
technical field [0001] The invention relates to a double-liquid screw valve capable of accurately monitoring flow, belonging to the technical field of machinery. Background technique [0002] In industrial production, dispensing is required in many places, such as integrated circuits, semiconductor packaging, printed circuit boards, color LCD screens, electronic components, and automotive parts. Most production scenarios only need to use a single glue for dispensing, but in some production scenarios, two different glues need to be mixed in a specific ratio. At this time, the precise control of the glue mixing ratio is very important to ensure production quality. . [0003] The double-liquid screw valve is a dispensing valve that can realize automatic glue mixing and dispensing. However, the existing dual-liquid screw valve lacks a flow monitoring module or the flow monitoring module has low accuracy, and cannot achieve accurate monitoring of the glue-liquid mixing ratio, w...
