Automatic wire feeding device with fault self-diagnostic function and diagnostic method

Abstract

The invention discloses an automatic wire feeding device with a fault self-diagnostic function and a diagnostic method. The automatic wire feeding device with the fault self-diagnostic function comprises an automatic wire feeding device, an alarm device and a control unit; the automatic wire feeding device comprises a base, a wire feeding guide pipe, a spring, a spring fixing cavity, a gear, a wire feeding stepping motor, a driven wheel, a movable bottom plate, a cross beam, a long bolt and a wire winding wheel; the wire feeding guide pipe is relatively fixed to the spring, and the spring fixing cavity is fixed at the bottom of the base; the gear is located at the output shaft of the stepping motor, the driven wheel and the cross beam are located on the movable bottom plate, and the gear is matched with the driven wheel to clamp wire-shaped materials; the long bolt abuts against the cross beam, and the long bolt is rotated to enable the bottom plate to slide left and right; the windingwheel is fixed at the top end of the base through a support; the alarm device comprises two micro-switches and two acousto-optic alarms, the micro-switches detect the wire shortage and the wire blockage respectively, and the alarms are used for giving out alarms of corresponding faults; and the control unit is used for circularly detecting the states of the two micro-switches in real time, and the corresponding alarms are started when faults occur.

Description

technical field [0001] The invention relates to an automatic wire feeding device with a fault self-diagnosis function and a diagnosis method, which are applied in welding manufacturing and FDM (Fused Deposition Modeling) additive manufacturing, and belong to the field of intelligent manufacturing. Background technique [0002] Wire feeding is a very important link in the field of machining. In recent years, the emergence of automatic wire feeding devices has greatly promoted the development of the manufacturing industry. This method overcomes the problems of poor accuracy, poor consistency, and unstable wire feeding by manual wire feeding. It is widely used in welding manufacturing, FDM (fused deposition) additive manufacturing and other fields. At present, there are many mechanisms for automatic wire feeding devices on the market, but their principles are similar. The general description is as follows: firstly, the wire feed is pressed into a narrow groove through the gea...

Problems solved by technology

Although the device can realize the automatic alarm function of wire blocking and broken wire, it cannot specifically diagnose the type of fault, and the fault diagnosis standard is not clear. In addition, two rotary encoders are used, and the cost is relatively high.
