Thermometer reference graduation automatic calibration and reticule device

Abstract

The invention relates to a device for automatically marking and marking the reference scale of a thermometer, comprising a stepping motor (1), a vertical slider assembly (2), a horizontal slider assembly (3), a marking pen (4) and an electromagnet ( 6), the vertical slider assembly (2) includes upper and lower brackets (2.1), ball screw (2.2), vertical guide rail (2.3) and vertical slider (2.4), stepper motor (1) The fixing device is on the top of the upper bracket (2.1), and the output end of the stepper motor (1) is connected to the top of the ball screw (2.2); the transverse slider assembly (3) includes a transverse guide rail (3.1) and a transverse slider (3.2 ), the horizontal guide rail (3.1) is connected to the vertical slider (2.4), and the marking pen (4) is connected to the front of the horizontal slider (3.2); the electromagnet (6) is placed on the connecting plate (14), The guide rod of electromagnet (6) links to each other with transverse slide block (3.2). The engraving pen of the invention can automatically carry out engraving calibration at the position of the reference scale line of the thermometer.

Description

technical field [0001] The invention relates to a device for calibrating the reference scale of a thermometer for measuring human body temperature - a device for calibrating and marking the reference scale of a thermometer, which is used in the production and manufacturing process of a thermometer to check the two reference lines (37°C and 37°C) on the thermometer. 41°C) to mark the scale. It belongs to the field of medical and sanitary machinery. Background technique [0002] Thermometers are used to measure body temperature and are the most conventional detection instruments in the medical and health system. Because of their ease of use and low price, they are also common medical and health devices in households today. Based on this feature, the annual production of thermometers is very large. [0003] The thermometer has a simple structure. It consists of a triangular glass tube with a capillary and a connected mercury glass bag. When measuring, place the watch on the m...

AI Technical Summary

Problems solved by technology

The measurement accuracy of the thermometer is 0.1°C, which requires high requirements. Therefore, in the production process of the thermometer, it is impossible to mark the reference line of the scale on the same position. In the current production, this process relies on manual operation. To carry out, this not only requires a lot of human resources, but also the scale error is relatively large
