Abstract

The invention discloses an electrochemical oxygen sensor packaging tool and a package protection method. The tool comprises a tool body, a sensor fixing chamber and an internal hexagon screw. The toolbody is a box-shaped structure with a hollow central portion; a threaded perforation is provided on the surface of the upper cover thereof; the sensor fixing chamber is fixed at the bottom thereof and corresponds to the position of the perforation; and tool fixing rods are provided at both ends thereof to connect and fix the upper cover of the tool and the bottom of the tool. The internal hexagonscrew can press through the perforation on the upper cover of the tool to press into the sensor fixing chamber. The package protection method using the tool is convenient to operate and is low in cost, and not only the same effects as ultrasonic packaging and ultrasonic welding can be achieved, but also the mechanical properties and corrosion resistance of the solder joints of the leads of the sensor are increased, moreover, the solder joints are sealed up and down, thereby the sealing property is better, which can solve the problem that the electrolyte leaks from the leads.

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...
