Description
The technical field is as follows:
the invention relates to an automatic sorting device for measuring the inner diameter of a gas detection glass tube, and belongs to the field of production and application of gas detection glass tubes.
Background art:
the gas detection tube is a gas detection device, is an instrument for chemical analysis methods, and is a tool for detecting gas content, which is simple, convenient and portable to operate. The detection tube is formed by filling a certain amount of detection agent into a gas detection glass tube with a fixed limited length and inner diameter, selecting and fixing a plug material according to the inner diameter size of the gas detection glass tube, and sealing and processing two ends of the gas detection glass tube. Before filling the detection agent, the inner diameter of the gas detection glass tube needs to be measured and sorted according to the measurement result so as to complete the subsequent process of selecting, matching and plugging materials, and then calibration is carried out, so that the accuracy of gas measurement is improved.
At present, the gas detection glass tubes are measured by adopting inner diameter plug gauges, sorting is carried out in a manual mode, each gas detection glass tube needs to try different plug gauges for 2-3 times to classify the gas detection glass tubes, the inner diameter detection precision is 0.1mm, and the method has the defects of low precision, low efficiency and the like. Therefore, the measurement and sorting of the inner diameters of the gas detection glass tubes of different batches and the same batch with different sizes are always difficult.
In the prior art, a micro glass tube detection device (publication No. CN113405492A, publication No. 2021.09.17) and a transparent quartz tube sorting machine (publication No. CN204074563U, publication No. 2015.01.07) are directed at the technical problem of glass tube defect detection, and both are respectively applicable to a diode and a quartz tube, but cannot solve the problem of inner diameter detection and sorting of a gas detection glass tube; a glass tube inner and outer diameter detection device (publication number CN208505192U, published date 2019.02.15) adopts contact measurement to realize inner and outer diameter detection, but the technology is slow relative to non-contact measurement and is not suitable for rapid detection and sorting; an automatic glass tube outer diameter detector (publication No. CN103008256A, published 2013.04.03) aims at the technical problem of detecting whether the outer diameter of a glass tube is within the tolerance range of a nominal size, is used for sorting qualified products and unqualified products, and cannot sort glass tubes with different sizes; a device for detecting the inner and outer diameters of glass tubes (publication No. CN110608701A published by 2019.12.24) is used for screening unqualified products with the inner and outer diameters of the glass tubes instead of sorting glass tubes with different sizes; the device for grading the micro blood sampling glass tubes and the detection grading system (publication No. CN207013306U, published date 2018.02.16) thereof are used for grading the micro blood sampling glass tubes, the occupied space is large, the reference problem is not considered when a CCD camera is used for measurement, the detection error is easy to generate in the transmission process, and the error in the transmission process has great influence on the measurement result by adopting a visual measurement method.
In summary, the detection of the glass tubes in the prior art is generally applicable to the detection of the surface defects of the glass tubes, and the diameter detection of the glass tubes is used for sorting qualified products and unqualified products, rather than sorting different batches of glass tubes with different sizes into material distribution boxes.
