The invention relates to the technical field of thermometer production, in particular to a device based on visual inspection and used for thermometer production. The device based on visual inspection and used for thermometer production mainly comprises a visual inspection part and a closed-loop feedback control part. According to the virtual inspection part, an industrial camera is utilized for obtaining measured images or videos, and a measurement result is given through image processing and data analysis. According to the closed-loop feedback control part, the measurement result and firing standards are compared in real time, a deviation value is given, firing parameters are adjusted, and firing work is finished through an executing mechanism. Due to the fact that the closed-loop processing mode is built by introducing a visual measurement link, full-automatic intelligent firing of a thermometer can be achieved, and the device has the advantages of being high in processing precision, efficiency and yield, and the like.
Description
technical field [0001] The invention relates to the technical field of thermometer production, in particular to a device for thermometer production based on visual detection. Background technique [0002] Most of the production and testing of thermometers in our country are carried out manually, and the degree of automation is not high. A key point and difficulty in the production process of the thermometer is the firing and testing of the necking structure of the inner tube of the thermometer. The necking structure of the inner tube of the thermometer determines the performance of the thermometer. The current firing mode in our country is all firing by workers. The process is mainly observed and fired by human eyes, and manually adjusted according to the degree of burning. Specifically, a projector is used to enlarge a part of the glass tube to be fired and observed in real time with the naked eye; after that, the flame is manually moved to the tube wall for burning. Acco...
