Problems solved by technology
[0005] This type of fiber optic sensor has the characteristics of high structural dimension accuracy and difficult installation. If the installation is not correct, or the fiber optic sensor bracket is deformed, the fiber optic probe is not fixed reliably, the fiber optic probe itself is deformed and loose, environmental or mechanical vibrations, etc. Structural changes will seriously affect the detection effect
Therefore, it is necessary to detect the fiber optic sensor before using it. At present, there is no detection device for the fiber optic sensor.

The invention provides a detection device for an optical fiber sensing device, which comprises a horizontal measuring plate and a vertical measuring plate vertically arranged on the horizontal measuring plate. Through arranging an optical fiber sensor on the vertical measuring plate, based on whether the gaps between optical fiber sensor probes and a measuring block group are measured to be the same according to a light transmission method principle, whether the optical fiber sensor probes are located in the same plane is determined. Through judging whether the optical path intersection between the optical fiber sensor probes is located in a longitudinal correction line, whether the included angle between the two optical fiber sensor probes meets requirements is determined, the measuring device has a simple structure, the making cost is low, the operation is simple, the optical fiber transmission device can be quickly detected, and the detection efficiency is improved.
Description
technical field [0001] The invention relates to the field of TFT glass manufacturing and testing equipment, in particular to a detection device and a detection method of an optical fiber sensing device. Background technique [0002] During the manufacturing process of automatic production equipment for TFT glass, it is necessary to detect the quality of the glass plate. Usually, there are two types of sensors for contact and non-contact detection. For contact sensors, there are hidden dangers such as scratches and pollution that have been detected by non-contact sensors. sensor instead. The representative of the non-contact sensor is the photoelectric switch, and the optical fiber sensor is widely used in the control system as the detection accuracy is high, the efficiency is high, and the failure is small. [0003] Glass for TFT has the characteristics of high optical transmittance. Due to the vertical reflection of the photoelectric switch, the light will penetrate after ...
