Abstract
A camera shooting illuminator for a cigarette packet comprehensive appearance quality online detection system is characterized by mainly comprising a main LED light source (1), side LED light sources (2) and an LED driving controller (3), wherein the main LED light source (1) is mounted in a main detection frame (4) which is mounted on a cigarette packet conveying device (5), the side LED light sources (2) are mounted at an inlet end and an outlet end of the main detection frame (4) respectively, and the main LED light source (1) and the side LED light sources (2) are respectively electrically connected with the LED driving controller (3) adopting a PWM (pulse-width modulation) normally-on control mode with the reference frequency of 100Hz. By the aid of the PWM 'normally-on' mode, a camera exposure need is met while harm to human eyes can be reduced, and the heating value is greatly reduced.
Description
Technical field
The utility model relates to a kind of tobacco machine, especially a kind of cigarette parcel appearance quality detection device, and specifically a kind of cigarette parcel integrated appearance quality on-line detection system is with the shooting illumination equipment.
Background technology
As everyone knows, cigarette capsule packing is the very important packaging process of cigarette factory, seriously influences if the inferior-quality tobacco bale of presentation quality comes into the market to bring very to corporate reputation.The conventional artificial method of inspection exists labour intensity big; The problem that loss is high; For this reason, application number is 200910029930.9, and denomination of invention is 201010520662.3 for " based on the plume of laser technology and graphical analysis or the method for inspection and the device of tobacco bale disappearance ", application number; Denomination of invention is " device that improves plume tobacco bale image detection image quality "; And application number is 201020577932.X, and denomination of invention has solved this type of problem well for the Chinese patent of " improving the device of plume tobacco bale image detection image quality " all adopts image processing techniques that the presentation quality of tobacco bale is detected; In order to guarantee to obtain desirable image, be necessary for camera corresponding illumination is provided.Because it is energy-conservation that the LED illuminating lamp has, the advantage that the life-span is long, therefore existing image detection device all adopts LED as lighting source.The dual mode that has commonly used is gone up in led light source control: 1, strobe mode, 2, direct Chang Liang.Adopt strobe mode, though prolonged the life-span, bigger to execute-in-place workman eye injury.Directly normal bright mode is less to visual impact, but because of its cal val is huge, can't normally use at all.
Summary of the invention
The purpose of the utility model is to hinder eye to the stroboscopic that existing LED illuminating lamp exists; The big problem of normal bright cal val; Design and a kind ofly neither can hinder eye, cal val is low again, and the stroboscopic type cigarette parcel integrated appearance quality on-line detection system of avoiding the human eye sensitizing range is with the shooting illumination equipment.
The technical scheme of the utility model is:
A kind of cigarette parcel integrated appearance quality on-line detection system is with the shooting illumination equipment; It is characterized in that it mainly is made up of LED main light source 1, LED sidelight source 2 and LED driving governor 3; Described LED main light source 1 is installed in the main testing stand 4; Main testing stand 4 is installed on the tobacco bale conveyer 5; Described LED sidelight source 2 is installed in respectively on the entrance point and exit end of main testing stand 4, and LED main light source 1 all is electrically connected with described LED driving governor 3 with LED sidelight source 2, and it is the normal bright master mode of PWM of 100Hz that described LED driving governor 3 adopts reference frequency.
LED particle in described LED main light source 1 and the LED sidelight source 2 is high bright high-power particle, and its illumination is not less than 90 lumens/watt.
The beneficial effect of the utility model:
The utility model utilizes the human eye light sensitivity principles, adopts high frequency stroboscopic LED particle to throw light on, and has both solved heating problem, can not damage human eye again.
The utility model has effectively been avoided the resolution scope of human eye, and the visual perception is last to think Chang Liang, but actual fluorescent lifetime is merely 20 ~ 30%.When having satisfied the camera exposure needs, greatly reduce power consumption and the cal val of itself again.
The utility model is simple in structure, and control is convenient, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1.
A kind of cigarette parcel integrated appearance quality on-line detection system is with the shooting illumination equipment; It mainly is made up of LED main light source 1, LED sidelight source 2 and LED driving governor 3; Described LED main light source 1 is installed in the main testing stand 4; Main testing stand 4 is installed on the tobacco bale conveyer 5; Described LED sidelight source 2 is installed in respectively on the entrance point and exit end of main testing stand 4, and LED main light source 1 all is electrically connected with described LED driving governor 3 with LED sidelight source 2, and it is the normal bright master mode of PWM of 100Hz that described LED driving governor 3 adopts reference frequency.LED main light source 1 wherein should adopt high bright high-power particle with the LED particle in the LED sidelight source 2, and its illumination is not less than 90 lumens/watt.
The utility model passes through to adopt high bright high-power (90 lumens/watt) LED particle as lighting source, and configuration constant-current driven chip (can directly purchase from market), light source moment good stability.Adopt PWM " Chang Liang " pattern (reference frequency is 100HZ) in the control, effectively avoided the resolution scope of human eye, the visual perception is last to think Chang Liang, but actual fluorescent lifetime is merely 20 ~ 30%.When satisfying the camera exposure needs, greatly reduce power consumption and the cal val of itself.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
