Background technology
Irradiating machine is as the equipment of UV curing solid, industries such as electronics, photoelectricity, biomedicine, the art work have been widely used in, its principle is to utilize focusing lampshade that light-resource fousing is become luminous point, by the UV photoconductive tube high-intensity UV light is transmitted to required irradiation position.Though the UV bulb is 100W only, but because focussing force, the UV light of its output can reach more than the 10W/cm2 (UVA), is about 100 times intensity of general area source, also have a kind of novel UV-LED irradiating machine, utilize the semiconductor light emitting technology to substitute the UV bulb with ultraviolet LED.
But all there is following problem in present irradiating machine: irradiating machine is used in converted products on the production line more, be in continuous duty, if the light source generation problem of irradiating machine, irradiating machine can't operate as normal, thereby make its product processed become waste product, cause the waste and the loss of product.And present UV-LED irradiating machine adopts is the crossing current type of drive, and illumination output is very sensitive to working temperature, and the irradiation head temperature is low when just working; illumination output is high, and along with the lengthening of operating time, the irradiation head temperature raises; illumination declines to a great extent, and can descend 20% usually.Cause irradiation output non-constant, influence product quality.
The utility model content
The purpose of this utility model is to propose a kind of irradiating machine, can report to the police automatically when its light source breaks down, and reduces the product loss.
For reaching this purpose, the utility model by the following technical solutions:
A kind of irradiating machine, comprise irradiation head, also comprise illumination photometry module, judging unit and memory cell, described illumination photometry module is connected with described judging unit, described judging unit is connected with described memory cell, and described illumination photometry module further comprises transducer, and described transducer is installed in described irradiation head inside, wherein
Described transducer is used to detect the surplus light that irradiation head sends;
Described illumination photometry module is used to obtain irradiation head illumination intensity of light source value, and issues described judging unit;

Adopted the technical solution of the utility model, when the light source of irradiating machine goes wrong, illumination is during less than the certain predetermined value, and irradiating machine can be reported to the police automatically, and closing device, thereby reduces the loss of product; When not breaking down, the illumination feedback signal can also be provided, realize the illumination FEEDBACK CONTROL, change drive current according to brightness value, improve illumination stability, improve product quality.
Description of drawings
Fig. 1 is the structural representation of irradiating machine in the utility model embodiment.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is the structural representation of irradiating machine in the utility model embodiment.As shown in Figure 1, this irradiating machine comprises irradiation head 1, illumination photometry module 2, judging unit 3, memory cell 4, alarm unit 5 and driver module 7, and the illumination photometry module further comprises transducer 6.
Transducer is installed in irradiation head inside, and the edge part of light source is sent at irradiation head in the position, can not block light source, can detect the surplus light of light source again.
Other positions, judging unit, memory cell, alarm unit and the driver module of illumination photometry module can be installed in the body of irradiating machine, judging unit is connected with illumination photometry module, memory cell and alarm unit respectively, and driver module is connected with irradiation head with judging unit respectively.
The workflow of irradiating machine is as follows:
At first, in memory cell, set brightness value and the desirable brightness value that light source breaks down.
Under the operating state of irradiating machine, the transducer that is positioned at irradiation head inside continues the surplus light of detection light source, and gives the illumination photometry module with the testing result loopback.
The illumination photometry module draws the illumination intensity of light source value, and this brightness value is sent to judging unit.
The brightness value that the current light source brightness value that judging unit will be sent from the illumination photometry module and the light source of cell stores break down is compared, if the brightness value that the current light source brightness value breaks down less than light source, judging unit can be exported the signal that goes wrong on the one hand, close the equipment of working, send alarm signal on the other hand to alarm unit, after alarm unit is received alarm signal, give the alarm.
If the brightness value that the current light source brightness value breaks down greater than light source, then make comparisons with desirable brightness value, low then increase drive current up to reaching desirable brightness value, height then reduces drive current up to reaching desirable brightness value, send the illumination feedback signal by judging unit to driver module, driver module is adjusted the illumination output of irradiation head according to the illumination feedback signal, thereby implements FEEDBACK CONTROL, improves illumination stability and control precision.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with the people of this technology in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
