Abstract
The utility model discloses a machine vision light source system capable of adjusting luminance in real time, which relates to the technical field of electronic product quality detecting and is used for providing constant lighting light source for electronic product quality detecting equipment. The machine vision light source system comprises light source equipment, an intelligent controller connected with the light source equipment and supplying power to the light source equipment, image collection equipment arranged above the light source and a computer respectively connected with the image collection equipment and the intelligent controller. A light source identifying module and a control module are arranged in the computer, and the light source identifying module sends commands to the intelligent controller through the control module. The machine vision light source system has the advantage of adopting constant current adjusting and guaranteeing that light source luminance is kept constant in a working process.
Description
Technical field
The utility model relates to electronic product Quality Detection technical field, is a kind of visual light origin system of electronic product Quality Detection instrument specifically.
Background technology
In suitability for industrialized production, intelligentized Quality Detection is generally used in the whole world, and the machine vision light source is the core component in this detection system.Light source is connected with a controller, and most of light sources are realized through controller regulator potentiometer (variable resistor) the control of its voltage, electric current; Through regulating operating voltage, the electric current that variable-resistance resistance value changes light source, thus the brightness of may command light source; But above control mode can not be controlled in real time, and when the brightness of light source changed, the voltage and current that controller provides can't compensate automatically, and it is constant that light-source brightness can not keep.
The utility model content
The task of the utility model is to solve the prior art problem, and a kind of machine vision light-source system that can real-time regulated brightness is provided, and makes light-source brightness can keep constant.
Technological means: the utility model discloses a kind of machine vision light-source system that can adjust brightness in real time, comprise light source, be connected and be the constant current intelligent controller of its power supply, the computer that is arranged on the image capture device of light source top and is connected with the constant current intelligent controller with image capture device respectively with light source; Wherein in computer, be provided with light source identification module and control module, light source identification module is sent instruction through control module to intelligent controller.
The cross section of light source is an annular, and the centre of its ring is the collection fenestra of image capture device; Light source comprises one group of LED bulb, pcb board and shell, and the LED bulb is welded on the pcb board, and is assemblied in the shell.
Image capture device is an industrial camera.
Beneficial effect: the utility model utilizes image capture device to obtain the image of testing product; When detecting; Light source identification module is carried out the real-time sampling analysis to the rgb value of image, according to the result who obtains, through control module intelligent controller is sent control signal in real time; To change the parameter that light source obtains power supply, reach the effect of brightness constancy.Because temperature can exert an influence to the work of LED lamp, so adopt the Current Regulation mode, intelligent controller is a constant-current controller, promptly is the constant operating current of LED lamp input through real-time regulated.
Description of drawings
Fig. 1 is the structural representation of the utility model product.
Embodiment
Be illustrated in figure 1 as the disclosed a kind of machine vision light-source system that can adjust brightness in real time of the utility model, this system comprises the light source 1 that is arranged on directly over the detected material 5, be connected with light source 1 and be the constant current intelligent controller 2 of its power supply, the computer 4 that is arranged on the image capture device 3 of light source top and is connected with constant current intelligent controller 2 with image capture device 3 respectively; Wherein in computer 4, be provided with light source identification module 41 and control module 42, light source identification module 41 is sent instruction through control module 42 to intelligent controller 2.
The cross section of light source 1 is an annular, and the centre of its ring is the collection fenestra of image capture device 2; Light source comprises one group of LED bulb, pcb board and shell, and the LED bulb is welded on the pcb board, and is assemblied in the shell; The image capture device 3 general industrial cameras that adopt; Adopting the constant current intelligent controller is that the just collimation of its optimum operating voltage can change because of the rising of LED bulb with temperature, so adopt the mode of constant flow regulation to reach optimum efficiency more easily.
