[0002] The nitrogen oxide sensor is a consumable in the exhaust gas analyzer in the automotive detection industry, mainly used to measure the concentrations of nitrogen oxides and oxygen in automotive exhaust. The outer shield of the nitrogen oxide sensor is an external protection device for the nitrogen oxide sensor, mainly used to protect the nitrogen oxide sensor from mechanical damage, water, dust and other environmental factors, and at the same time ensure the working stability and reliability of the sensor. Pressing the outer shield of the nitrogen oxide sensor is a process of correctly installing the outer shield of the nitrogen oxide sensor on the sensor and making it closely combined with the sensor. This process needs to ensure the sealing and stability between the outer shield and the sensor to prevent interference and damage from the external environment. The existing pressing equipment, during use, is configured with a one-way part conveying structure, and the pressing accuracy of the equipment may not be high, resulting in the outer shield not being pressed in place or having deviations, affecting the performance of the sensor.
