The spray paint lighting device of rear surface particle of testing product
Technical field
The invention belongs to Quality Detection operation device, be specifically related to the spray paint lighting device of rear surface particle of a kind of testing product, especially be fit to the detection of Car Body Painting particle.
Background technology
In the process that detects for car body coating grain defect point, existing detection method is to adopt the fluorescent tube irradiation vehicle body performance of gathering, and detected material is in a high-brightness environment, and illumination reaches more than the 3000lux, manually carries out particle detection.This method reveals particle by brightness, and loss is very high, and the testing staff is under this environment 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 the spray paint lighting device of rear surface particle of a kind of testing product, adopt the method for zebra illumination that the car body coating particle is detected.
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 lighting device is comprised of inverted U-shaped the first portal frame and the fluorescent tube that skeleton forms, and fluorescent tube evenly gathers on framework; Be provided with the second portal frame in the first portal frame, be fixed with the zebra film on the second portal frame, the zebra film is corresponding with lamp strip position.
Further, described indoor two tracks that arrange, the second portal frame is slidably mounted on the track.
Further, described the second portal frame is comprised of the transverse connection that longitudinal bracing frame and interval are fixed on the bracing frame, and is surperficial perpendicular to the zebra film by the connector that band steel is made.
Preferably, described zebra film is that light transmittance is≤40% film, and film has the black and white strip of alternative arrangement.
More preferably, the distance of described zebra film and fluorescent tube is 200mm-300mm.
The spray paint lighting device of rear surface particle of testing product of the present invention, adopt the method for zebra illumination can make the vehicle body particle under the zebra houselights clearly, more easily be found, reduce the loss of particle.
The present invention is owing to adopting two independently frameworks, and the second portal frame setting is also in orbit front and back slip in orbit, the second portal frame can be adjusted according to the vehicle body position at any time, effectively raise operating efficiency, movably the second portal frame makes things convenient for illumination apparatus to carry out maintaining simultaneously.
Houselights of the present invention separates by the zebra film, and the soft light environment makes the staff not have obvious sense of discomfort.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
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 that is fixed on the body floor, chamber, lighting device 1 comprises on inverted U-shaped the first portal frame 1.1, the first portal frames 1.1 that formed by skeleton and evenly is densely covered with fluorescent tube 1.2.Be provided with inverted U-shaped the second portal frame 2 and the zebra film 3 that is fixed on the second portal frame 2 in the lighting device 1, it is inner corresponding with fluorescent tube 1.2 positions 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 the first portal frame 1.1, guarantees that fluorescent tube 1.2 can be arranged on the first portal frame 1.1 uniformly.
As shown in Figure 3, two tracks, 2.3, the second portal frames 2 being set on the chamber body floor is slidably mounted on the track.Lighting device 1 is fixed on the platform, and the second portal frame 2 can illumination apparatus 1 carry out maintaining behind a Slideslip.The second portal frame 2 is comprised of the transverse connection 2.2 that longitudinal bracing frame 2.1 and interval are fixed on the bracing frame 2.1, bracing frame 2.1 is welded by section bar, bracing frame 2.1 and connector 2.2 be whole to form as shown in Figure 1 inverted U-shaped second portal frame 2 corresponding with the first portal frame 1.1 of lighting device, zebra film 3 smooth being fixed on regularly on the second portal frame 2.Connector 2.2 is made by band steel, perpendicular to zebra film surface, to guarantee that irradiation can not form shade at film.
Zebra film 3 is to form light transmittance by the black streaking 3.1 about width 110mm and informal voucher line 3.2 alternative arrangements to be≤40% film square, characteristics high temperature resistant, the printing opacity uniform-illumination that this film has as shown in Figure 4.
The process that the present invention detects vehicle body grain defect point is: will fill bright device 1 and fluorescent tube 1.2 and be combined into light source, and see through the zebra film and shine on the vehicle body, and form hot spot, a material defect point can be operated easily personnel and find.The distance of fluorescent tube 1.2 and zebra film 3 guarantees between 200mm-300mm, and illumination is more than 5000lux before seeing through the zebra film for fluorescent tube like this, and the illumination that sees through behind the zebra mould is reduced to 2000lux, makes operating personnel's eyes avoid the infringement of light source.Stepless dimming is adopted in the simultaneously control of fluorescent tube 1.2, can make operating personnel more convenient at any time according to different operating personnel's custom different adjustment brightness, operates more humane.
