Description

Technical Field

[0001] The utility model relates to the technical field of ceramic pressure sensors, in particular to grade sorting equipment for ceramic pressure sensors. Background Art

[0002] Ceramic pressure sensor, without liquid transmission, pressure acts directly on the front surface of the ceramic diaphragm, causing the diaphragm to produce a slight deformation, thick film resistors are printed on the back of the ceramic diaphragm, connected to form a Wheatstone bridge, the ceramic pressure sensor is mainly composed of three parts: ceramic ring, ceramic diaphragm and ceramic cover. The ceramic diaphragm is used as a force-sensitive elastic body and is made of 95% AL2O3 porcelain. It is required to be flat, uniform and dense. Its thickness and effective radius depend on the design range. The ceramic ring is formed by hot die casting and high temperature sintering. High temperature glass slurry is used between the ceramic diaphragm and the ceramic ring. Through thick film printing and hot sintering technology The two components are fired together to form a force-sensitive cup-shaped elastomer with a peripheral fixed support. That is, a rigid structure without creep should be formed in the peripheral fixed support part of the ceramic. The circuit of the sensor is made into the upper surface of the ceramic diaphragm, that is, the bottom of the ceramic cup, using thick film technology. The circular groove at the bottom of the ceramic cover forms a certain gap between the cover and the diaphragm. The limiter can prevent the diaphragm from breaking due to excessive bending when overloaded, thus forming an anti-overload protection for the sensor. Temperature drift: As the temperature changes, the activity of the carriers in the ceramic pressure sensor will also change, which will cause changes in other parameters. This change is slow and is called temperature drift, or temperature drift for short.

[0003] In the prior art, a Chinese patent document with patent number CN212143518U proposes a ceramic pressure sensor grade sorting device, including a base, a fixed box, a high-quality collection box, a conveyor belt, a pushing mechanism, a defective collection box and a detector. The ceramic pressure sensor is placed on the conveyor belt. When it is transported to the bottom of the detector, it is detected by the detector. After the detection is completed, when the detector detects that the quality of the ceramic pressure sensor is poor, the ceramic pressure sensor slides into the defective collection box through the slide plate 1. If the quality is qualified, the ceramic pressure sensor will slide into the high-quality collection box through the conveyor belt and the slide plate 2 to complete the grade sorting of the ceramic pressure sensor. However, in actual use, the ceramic pressure sensor grade sorting device cannot grade the ceramic pressure sensor according to its weight, resulting in the inability to achieve the effect of ceramic pressure sensor grade sorting.
