Dual-flow-meter type digital spraying system for robot

Abstract

The invention provides a dual-flow meter type digital spraying system for a robot. The dual-flow-meter type digital spraying system partially consists of a fluid part, an air path part and a control part. The fluid part uses a circular feeding mode. Digital flow meters are respectively connected in series with a feeding pipeline and a feeding-back pipeline, so that a feeding flow and a feeding-back flow can be detected in real time. A pneumatic proportional valve is further connected in series with the feeding pipeline, so as to realize long-distance flow adjustment. The air path part is divided into six paths for supplying compressed air to each pneumatic element; electric proportional valves are connected in series with the air paths to realize long-distance adjustment; the control part consists of an upper computer and a PLC (Programmable Logic Controller) and is respectively connected with the electric proportional valves and the flow meters. The dual-flow meter type digital spraying system provided by the invention can be used for real-time flow detection and closed-loop control of a spray gun in a circular feeding mode, and is further provided with a coating pump, a stirrer, a spray gun switch and long-distance adjustment capacities of atomized air and fan width air. Particularly, the dual-flow meter type digital spraying system is applicable to the field of feeding at an in-gun circulating modem and is inconvenient to manual detection flow or a flow decay phenomenon is easy to occur.

Description

technical field [0001] The invention relates to a double-flow meter digital spraying system for a robot, which belongs to the technical field of robot spraying. Background technique [0002] At present, industrial products have higher and higher requirements for the coating surface quality and paint film thickness precision sprayed by robots. On the premise that the robot motion accuracy is already high enough, the bottleneck that restricts the further improvement of the spraying operation quality lies in the flow control accuracy of the spraying robot. . However, ordinary constant pressure spraying systems cannot monitor flow fluctuations in spraying operations in real time, and lack effective remote adjustment means. Therefore, there is an urgent need for an automatic spraying system capable of real-time detection and remote adjustment of the spray gun flow. [0003] Through the investigation of published literature, patents, and industrial products, it is found that the...
