Pressurization detection device of pressure sensor

Abstract

The invention discloses a pressurization detection device of a pressure sensor. The detection device comprises a machine body, a conveying cavity is formed in the machine body; and a conveying deviceis arranged in the conveying cavity. The conveying device comprises a first conveying belt and a second conveying belt which can rotate. The first conveying belt and the second conveying belt have thesame rotating directions and are used for conveying sensors. According to the invention, the conveying device drives the sensor to convey rightwards; in the delivery process, the pressure of the sensor is detected through the detection device and a pressurizing device; the detection process is in full automation; each sensor can be detected, so that the detection accuracy and the pass percentageare improved. Besides, the detected qualified sensors are directly output rightwards to be packaged, the unqualified sensors are output backwards to be recycled in a centralized mode, so that automatic rejecting work of defective products is realized. The device is high in working efficiency and detection precision, automatic in operation and convenient to use.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a pressure detection device for a pressure sensor. Background technique [0002] A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. With the wide application of pressure sensors, it is very important to determine how to detect pressure sensors. Usually there are bridges There are three methods: road detection, zero point detection and pressure detection. Among them, the pressure detection is to supply power to the sensor, pressurize the air guide hole of the sensor, and use the voltage of the multimeter to detect the voltage change of the output terminal of the sensor. If the relative pressure of the pressure sensor The sensitivity is very high, and the amount of change will be obvious.

[0002] A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. With the wide application of pressure sensors, it is very important to determine how to detect pressure sensors. Usually there are bridges There are three methods: road detection, zero point detection and pressure detection. Among them, the pressure detection is to supply power to the sensor, pressurize the air guide hole of the sensor, and use the voltage of the multimeter to detect the voltage change of the output terminal of the sensor. If the relative pressure of the pressure sensor The sensitivity is very high, and the amount of change will be obvious. However, the existing pressurized detection device performs random inspection on the sensor, which is poor in comprehensiveness and increases the number of unqualified products. In addition, the existing pressurized detection process is usually carried out manually and assisted by a pressure gauge. The efficiency of manual work is low, and there are human errors in the detection, and the accuracy is low
