Testing product sprays paint the lighting device of rear surface particle
Technical field
The invention belongs to Quality Detection process device, be specifically related to a kind of testing product and spray paint the lighting device of rear surface particle, be especially applicable to the detection of Car Body Painting particle.
Background technology
In the process detected for car body coating grain defect point, existing detection method adopts the fluorescent tube that gathers to irradiate vehicle body performance, and detected material is in a high-brightness environment, illumination reaches more than 3000lux, manually carries out particle detection.This method makes particle reveal by brightness, and loss is very high, and testing staff in such circumstances simultaneously, and eyes can be come to harm by strong illumination for a long time, endanger healthy.
Summary of the invention
The object of the present invention is to provide a kind of testing product to spray paint the lighting device of rear surface particle, adopt the method for zebra illumination to detect car body coating particle.
Technical scheme of the present invention is: the spray paint lighting device of rear surface particle of a kind of testing product comprises lighting device, and inverted U-shaped first portal frame that lighting device is formed by skeleton and fluorescent tube form, and fluorescent tube evenly gathers on framework; Be provided with the second portal frame in first portal frame, the second portal frame be fixed with zebra film, zebra film is corresponding with lamp strip position.
Further, described indoor arrange two tracks, and the second portal frame is slidably mounted on track.
Further, the transverse connection that described second portal frame is fixed on bracing frame by longitudinal bracing frame and interval forms, and the connector be made up of band steel is perpendicular to zebra film surface.
Preferably, described zebra film to be light transmittance be≤40% film, film has the black and white strip be alternately arranged.
More preferably, the distance of described zebra film and fluorescent tube is 200mm-300mm.
Testing product of the present invention sprays paint the lighting device of rear surface particle, adopts the method for zebra illumination that vehicle body particle can be made clearly, to be more easily found under zebra houselights, reduces the loss of particle.
The present invention is owing to adopting two independently frameworks, and the second portal frame arranges in orbit and can slide anteroposterior in orbit, second portal frame can adjust according to vehicle body position at any time, effectively raise operating efficiency, moveable second portal frame facilitates illumination apparatus to carry out maintaining simultaneously.
Houselights of the present invention is separated by zebra film, and soft light environment makes staff not have obvious sense of discomfort.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the spray paint lighting device of rear surface particle of testing product of the present invention comprises the lighting device 1 be fixed on body floor, room, lighting device 1 comprises on inverted U-shaped first portal frame 1.1, first portal frame 1.1 that formed by skeleton and is evenly densely covered with fluorescent tube 1.2.The zebra film 3 being provided with inverted U-shaped second portal frame 2 in lighting device 1 and being fixed on the second portal frame 2, it is inner corresponding with fluorescent tube 1.2 position that zebra film 3 is positioned at lighting device 1 first portal frame 1.1.
As shown in Figure 2, lighting device 1 is welded into skeleton by angle steel, and skeleton is inverted U-shaped first portal frame 1.1, ensures that fluorescent tube 1.2 can be arranged on the first portal frame 1.1 uniformly.
As shown in Figure 3, body floor, room is arranged two tracks 2.3, second portal frame 2 to be slidably mounted on track.Lighting device 1 is fixed on platform, and the second portal frame 2, after a Slideslip, illumination apparatus 1 can carry out maintaining.The transverse connection 2.2 that second portal frame 2 is fixed on bracing frame 2.1 by longitudinal bracing frame 2.1 and interval forms, bracing frame 2.1 is welded by section bar, bracing frame 2.1 and connector 2.2 entirety form inverted U-shaped second portal frame 2 corresponding with the first portal frame 1.1 of lighting device as shown in Figure 1, and zebra film 3 is smooth to be fixed on the second portal frame 2 regularly.Connector 2.2 is made up of band steel, perpendicular to zebra film surface, can not form shade to ensure that illumination is penetrated on film.
Zebra film 3 is alternately arranged by the black streaking 3.1 of width about 110mm and informal voucher line 3.2 to form the film square that light transmittance is≤40% as shown in Figure 4, and this film has feature that is high temperature resistant, printing opacity uniform-illumination.
The process that the present invention detects vehicle body grain defect point is: will fill bright device 1 and fluorescent tube 1.2 is combined into light source, be irradiated on vehicle body through zebra film, forms hot spot, and a material defect point can be found by operating personnel easily.The distance of fluorescent tube 1.2 and zebra film 3 ensures between 200mm-300mm, and such fluorescent tube illumination before through zebra film, at more than 5000lux, is reduced to 2000lux through the illumination after zebra mould, made operating personnel's eyes from the infringement of light source.The control of fluorescent tube 1.2 simultaneously adopts stepless dimming, at any time according to the custom different adjustment brightness of different operating personnel, operating personnel can be made more convenient, operate more humane.
