Problems solved by technology

[0002] In the packaging process of temporarily storing semi-finished glass substrates in the liquid crystal glass processing line, it is necessary to store the finished glass substrates by placing a special wrapping paper between each glass. Take a piece of paper and complete the whole packaging action, but the defects of the automatic paper feeding system often cause the problem of unstable paper output, so that it often happens that the robot grabs too much paper at one time or fails to grab it, seriously It affects the normal progress of packaging, which in turn affects the normal operation of the production line as a whole
At present, no technology and product to solve this kind of problem have been found in this technical field in China

Embodiment Construction

[0017] The mode step of the inventive method is as follows:

[0018] (1) A set of fiber optic sensors is required, that is, a fiber optic transmitter and a receiver, and the fiber optic sensor is connected to a fiber optic digital amplifier, and the fiber optic sensor is connected to the electrical control system;

[0019] (2) First install the fiber optic transmitter and receiver at a suitable position on the paper loading machine, and adjust the fiber optic transmitter and receiver to a suitable angle so that the light beam can pass through the paper vertically, and then fix the position of the fiber optic sensor;

[0020] (3) Connect the above optical fiber components with an optical fiber digital amplifier, and perform paperless optical fiber detection to see if it can work normally. Perform more than 4 times including 4 times at the above fixed position, for example, perform 6 times of direct beam detection and record it. The average value of signal strength X0;

Abstract

The invention relates to a method for detecting the number of paper on a liquid crystal flat glass production line, which adopts an extremely simple optical fiber sensing mode to detect. A mounting support, an optical fiber sensor, a data optical fiber amplifier and an alarm device and the like are mainly comprised. The mounting support is of an adjustable device and is used for fixing the optical fiber sensor and other equipment in appropriate space positions, and adjusting an optical fiber head to the best detecting angle and distance according to requirement, and the optical fiber sensor especially for detecting paper, glass substrates and the like is used for beam irradiation on objects so as to complete data collection; the data optical fiber amplifier is used for signal processing; and then an alarm is given by electrical control through feedback data or the movement of robots and other corresponding control. The invention can perfectly solve the problems that the robots always grasp two or more packaging paper when the glass substrates are primarily packaged, with the advantages of simplicity, high precision, high sensitivity, high processing speed and the like, and can be suitable for various demanding occasions.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal flat glass production, and in particular relates to a method for detecting the amount of paper produced by an optical instrument in an automatic paper loading system, and a detection system thereof. Background technique [0002] In the packaging link of temporary storage of semi-finished glass substrates in the liquid crystal glass processing line, it is necessary to store the finished glass substrates by placing a special wrapping paper between each glass. Take a piece of paper and complete the whole packaging action, but due to the defects of the automatic paper loading system itself, the paper output is often unstable, so that it often happens that the robot grabs too much paper at one time or does not grab it, seriously It affects the normal progress of packaging, which in turn affects the normal operation of the production line as a whole. At present, no technology and product to solv...
