Edge detector used by deviation-correcting system

Abstract

Provided is an edge detector used by a deviation-correcting system. The edge detector comprises a projector, a lens, a 2D digital sensor, and a microprocessor which are disposed in a housing. The protector and a material to be detected are vertically arranged on a transmitting end. The lens and the 2D digital sensor are arranged on a reflection end, on the same side of the projector, and in the same plane with the projector. The microprocessor is electrically connected with the 2D digital sensor. The projector generates visible light. Focused by the lens, the visible light is received by the 2D digital sensor. Finally, after the filtering and the analysis of the microprocessor, an edge position signal is output. The deviation-correcting system may control the moving direction and the moving distance of the material to be detected so long as receiving the edge position signal. The edge detector is free of independent emitting light source, high in deviation-correction precision, convenient to install, easy to debug, and convenient to maintain so as to be widely used in rubber and printing industries.

Description

technical field [0001] The invention relates to the technical field of deviation correction, in particular to an edge detector applied to a deviation correction system. Background technique [0002] The deviation correction system is composed of a controller, an actuator, a detector, a deviation correction mechanism and accessories. The detector detects the current position of the material in real time and sends the corresponding information to the controller. The controller compares the actual position and the set position of the material For comparison, if there is a difference, the controller sends the corresponding correction information to the actuator, and the actuator drives the actuator to correct the position of the material. [0003] In the rubber industry, from fiber calenders (double-ring control cord fabric spreading system, three-finger system, wide-range centering, cloth curling, etc.), inner lining calenders, composite extrusion lines (composite centering, ma...

AI Technical Summary

Problems solved by technology

[0004] However, the existing deviation correction system has some defects in application: for example, the deviation correction system has a rotating forming drum at the position of the template of the rubber molding machine. Only when the center of the drum is consistent can the tire embryo be qualified in terms of uniformity and other quality after molding. No matter what method is used for the current deviation correction detector, it is necessary to use an emitting light source or a reflector, which is difficult to adjust because the installation position is very close to the forming drum. , at the same time, it cannot be infinitely close to the forming drum, and it is difficult to ensure the center position of the drum after deviation correction. The existing deviation correction system requires the sensor to be consistent with the light path of the light source or reflector, and the system debugging is troublesome
