Automatic sorting device for measuring inner diameters of gas detection glass tubes

Abstract

The invention discloses an automatic sorting device for measuring the inner diameter of a gas detection glass tube. The automatic sorting device comprises a feeding module, a transmission module, a measuring module, a sorting module, a control module and a rack. The feeding module is used for storing glass tubes to be detected and is matched with the conveying module through an inclined slide way to realize separation of single glass tubes; the transmission module sequentially conveys the glass tubes to the alignment station, the measuring station and the sorting station one by one, alignment of one ends of the glass tubes is achieved through the alignment mechanism, and the measuring basis is unified. The measuring module acquires an end face image of the glass tube through an industrial camera to measure the inner diameter, and a measuring result is displayed through a monitoring interface and sent to the control module through a network to serve as a sorting basis; the sorting module controls the rotation angle of a sorting plate through a motor according to a measurement result, so that the glass tubes fall into a receiving box in a classified manner; the control module achieves movement of the transmission motor and position control of the sorting motor by writing a PLC control program, and material receiving box replacement and feeding work are carried out according to prompts of a monitoring interface.

Description

Technical field: [0001] The invention relates to an automatic sorting device for measuring the inner diameter of a gas detection glass tube, belonging to the field of production and application of a gas detection glass tube. Background technique: [0002] The gas detection tube is a gas detection device, which instruments the chemical analysis method, and is a simple, convenient and portable tool for detecting gas content. The detection tube is filled with a certain amount of detection agent in a gas detection glass tube with a fixed and limited inner diameter. According to the inner diameter of the gas detection glass tube, you need to select a plug to fix it, and then seal the two ends of the gas detection glass tube. made. Before filling the detection agent, the inner diameter of the gas detection glass tube needs to be measured and sorted according to the measurement results, so as to complete the subsequent plugging process, and then scale calibration to improve the ac...
