A device and method for automatic adjustment of hot wire

Abstract

The invention discloses a hot wire automatic adjustment device and method, comprising: a frame, a hot wire fixing frame, a mold fixing frame, a hot wire, a detection module, a sliding driving mechanism and a control system, and the control system is respectively connected with the detection module and the sliding The sliding drive mechanism is electrically connected; the control system is used to receive the detection signal of the detection module and control the action of the sliding drive mechanism. The invention adopts the hot wire fixing frame to realize the adjustment and fixation of the hot wire, and uses the detection module to detect the position and state of the hot wire in real time. Once the hot wire is bent, deformed or blown, the detection module will timely feedback to the control system, and the control system It will control the action of the sliding drive mechanism or the alarm, tighten the hot wire in time to restore the hot wire to the tensioned state, or give an alarm to the operator, so as to eliminate the abnormality. The invention can monitor the state of the hot wire in time, and make corresponding actions according to the detection signal fed back by the detection module, thereby effectively improving the film coating quality and qualified rate of the mould.

Description

technical field [0001] The invention relates to the technical field of chemical vapor deposition coating equipment, in particular to a hot wire automatic adjustment device and method. Background technique [0002] Chemical vapor deposition coating equipment uses various energy sources such as heating, plasma excitation or light radiation through chemical reaction to make gaseous or vapor state chemical substances react on the solid interface to form a layer of film in the coating equipment. In the actual reaction process, it is necessary to pass the hot wire through the center of the inner hole of the mold and keep it parallel to the axis of the mold, and then energize the hot wire for heating. Because the hot wire is easy to elongate at high temperature, it will cause bending deformation in the high temperature range, and it will be out of the original position. The quality problem of the hot wire will even directly fuse. The bending deformation or melting of the hot wire w...
