Abstract

The invention relates to a test device of a pressure sensor. The objective of the invention is to solve the technical problem of failure to achieve highly efficient, precise and automatic test in the current manually produced FPC pressure sensor. According to the invention, by adopting the technical scheme of combining a mechanical tool and electronic data processing, test results of the FPC pressure sensor can be displayed in real time; grade division is performed on the products; rapid, highly efficient and precise test on the FPC pressure sensor is achieved; automation degree of the test is effectively improved; above problems are well solved; and the test device can be used in industrial production of the FPC pressure sensors.

Description

technical field [0001] The invention relates to the field of pressure sensors, in particular to a test device for a pen tip pressure sensor of a computer input device. Background technique [0002] The pen tip pressure sensor is composed of FPC, PE conductive foam and white silicone pad, because it can distinguish the pressure when writing, so as to reflect the real handwriting, and the production method is simple and the cost is low, so it is practical Sex is extremely high. However, since the production is all manual, it is difficult to ensure the consistency of the production process, resulting in certain differences in the output of the FPC pressure sensor, making the pressure value reflected by the pressure sensor too large or too small. Therefore, the FPC pressure sensor after manual production must pass a screening before it can be used. The current screening method is mainly realized by visual observation, which is inefficient and unable to carry out accurate scree...
