Abstract

The invention discloses a tool for packaging an electrochemical oxygen sensor and a package protection method. The tool includes a tool body, a sensor fixing chamber and an inner hexagonal screw; wherein, the tool body is hollowed out in the middle Box-shaped structure, the surface of the upper cover is provided with a threaded perforation, the bottom of which is fixed with a sensor fixing chamber corresponding to the position of the perforation, and two ends are provided with fixture fixing rods for connecting and fixing the upper cover of the fixture and the fixture. The bottom of the tool; the inner hexagon screw can be pressed into the sensor fixing chamber through the perforation of the upper cover of the tool. The method of encapsulation and protection using this tool is easy to operate and low in cost. It can not only achieve the same effect as ultrasonic encapsulation and ultrasonic welding, but even increase the mechanical properties and corrosion resistance of the soldering points of the sensor pins. Sealing, better sealing, can solve the problem of electrolyte leakage from the pin.

Description

technical field [0001] The invention belongs to the field of electrochemical gas sensor processing, and in particular relates to a tool for packaging an electrochemical oxygen sensor and a packaging protection method. Background technique [0002] As the core and most basic link of the Internet of Things, sensors are a bridge between various information and artificial intelligence, and gas sensors, which belong to an important category, are commonly used sensors to ensure people's production and life safety. Emissions, etc., the working environment is different, sometimes they will be exposed to corrosive gases, and sometimes they will encounter large mechanical vibrations. [0003] The bottom of the liquid electrolyte electrochemical oxygen sensor has two gold-plated pins connected to the positive and negative silver conductive wires in the sensor cavity, and the generated current signal is output to the instrument for signal processing. Conventional electrochemical oxygen...
