[0002] Humidistor is made of the principle that humidity-sensitive material absorbs moisture in the air and causes its own resistance to change. The characteristic of humidity-sensitive resistor is that a film made of moisture-sensitive material is covered on the substrate. When When the water vapor in the air is adsorbed on the moisture-sensitive film, the resistivity and resistance value of the element will change, and the humidity can be measured by using this characteristic. However, the existing measurement is mainly to drop water on the humidity-sensitive resistor. This method Detection takes a long time and is not suitable for batch detection

The invention discloses a measuring device for power electronic components, which comprises a machine body and a pushing cavity in the body, a component box is arranged in the pushing cavity, an entrance communicating with the outside is set on the top wall of the component box, and the bottom of the component box is The wall is provided with a drop opening communicating with the push chamber, and the bottom wall of the push chamber is provided with a push motor, and the upper end of the push motor is connected to a camshaft for power, and a cam is fixed on the camshaft. The right end of the cam extends into the component box, and the present invention can automatically detect a plurality of humidity sensitive resistors, and use concentrated sulfuric acid to detect the performance of the humidity sensitive resistors, because concentrated sulfuric acid has water absorption and can Water accumulates on the humidity sensitive resistor to shorten the detection time, and the concentrated sulfuric acid dripped on the humidity sensitive resistor can be extracted and processed, and then reused for the detection of the next humidity sensitive resistor. Different amounts of concentrated sulfuric acid are added dropwise.
Description
technical field [0001] The invention relates to a measuring device for power electronic components, and mainly relates to the technical field of electronic component detection. Background technique [0002] Humidistor is made of the principle that humidity-sensitive material absorbs moisture in the air and causes its own resistance to change. The characteristic of humidity-sensitive resistor is that a film made of moisture-sensitive material is covered on the substrate. When When the water vapor in the air is adsorbed on the moisture-sensitive film, the resistivity and resistance value of the element will change, and the humidity can be measured by using this characteristic. However, the existing measurement is mainly to drop water on the humidity-sensitive resistor. This method Detection takes a long time and is not suitable for batch detection. For above-mentioned shortcoming, the present invention has been improved. Contents of the invention [0003] The technical pro...
