Embodiment approach

[0024] (1) The verification personnel install the electronic thermometer on the fixture frame 10 of the electronic thermometer, and put the fixture frame 10 on the first conveyor belt 12;

[0025] (2) The upper computer 19 sends instructions to the PLC programmable controller 17, controls the cylinder 4 to lower the guide rail 2, and controls the first motor 13 to drive the conveyor belt to rotate to transport the fixture frame 10 to the end close to the first constant temperature bath 11, Control the stepping motor 8 to rotate the guide rail 2 so that the fixing part 9 is located under the fixture frame 10, and then the guide rail 2 is raised so that the fixing part 9 lifts the fixture frame 10;

[0026] (3) Control the stepper motor 8 to rotate the guide rail 2 so that the first fixture frame is facing the first constant temperature bath, control the cylinder 4 to make the guide rail 2 descend, and the sensor part of the electronic thermometer is immersed in the medium of the...

Abstract

The invention discloses an automatic on-line verification system for electronic thermometers. Four thermostatic baths and two conveying belts are equidistantly disposed on six annular equipartition point centering on a control platform, an annular guide rail is mounted above the control platform, three load-bearing wheels are equidistantly mounted on three equipartition points on the outer side of the annular guide rail, support platforms, cylinders and the load-bearing wheels are coaxially mounted, a gear is mounted on the inner side of the annular guide rail and is coaxially mounted with a stepping motor, six mounting fixing parts are equidistantly arranged on the annular guide rail, a fixture frame is mounted on each fixing part, all motors and cylinders are connected with a PLC (programmable logic controller) and then connected with an upper computer, each thermostatic bath is internally provided with a standard thermometer which is sequentially connected with a secondary instrument and the upper computer, and a CCD (charge coupled device) camera connected with the upper computer and a light source are mounted on the outer side of each thermostatic bath. By the aid of design of the fixing parts and the fixture frames and arrangement of the conveying belts, verification efficiency of the thermometers is improved, and verification automation degree is also improved.

Description

technical field [0001] The invention relates to a verification system of an electronic thermometer, in particular to an automatic online verification system of an electronic thermometer applied to an electronic thermometer production line. Background technique [0002] Mercury thermometers have been gradually banned by the European Union, the United States and other countries because of the leakage of toxic liquid mercury due to a little carelessness in use. Due to the advantages of safety, convenient reading, and sensitive temperature measurement, electronic thermometers are becoming more and more popular. In order to ensure the accuracy of the temperature measurement of the electronic thermometer, it is necessary to test the technical index of the temperature measurement accuracy of the electronic thermometer. At this stage, manufacturers of electronic thermometers are all done manually. The manual verification of the electronic thermometer is to place the electronic the...
