Embodiment Construction

[0039] first reference Figure 1 to Figure 4 . A device for optically examining a surface area of ​​an object 12 is indicated overall by 10 there. In the present example, a body 14 is shown as object 12 ; some surface regions to be inspected are indicated with 16 . During the test, the entire surface of the object 12 is tested by continuously monitoring the individual surface regions 16 one after the other.

[0040] As explained at the outset, the painted bodywork 14 is guided through the facility 10 in order to be visually checked by testers for the quality of the paintwork. For this purpose, the installation includes a test chamber 18 with a housing 20 through which the vehicle body 14 can be guided by means of a conveyor system 22 . In the present embodiment, the conveyor system 22 comprises a roller conveyor 24 on which so-called conveyor trolleys can be transported such that 26 , the transport trolley generally forms a load-bearing structure and the body 14 is then f...

Abstract

The invention relates to an installation for the optical inspection of surface regions (16) of objects (12), in particular painted vehicle bodies (14), comprising a test light device (28), by which objects (12) located in a test region (18a) can be irradiated with a test light (30) and by which a test pattern (32) can be generated on the surface region (16). A lighting system (42) comprises a plurality of lighting units (50, 64), by which test light (30) can be emitted. The color of light or both the color of light and the light intensity of the test light (30) can be optionally adjusted by means of the lighting units (50, 64).

Description

technical field [0001] The invention relates to a device for optically examining a surface area of ​​an object, in particular a painted body, comprising: [0002] a) a test light device by means of which an object located in the test area can be irradiated with test light and a test pattern can be produced on the surface area; [0003] b) A lighting system comprising a plurality of lighting units by means of which test light can be emitted. [0004] The invention also relates to a lighting system for said facility, having at least a first lighting device and a second lighting device, wherein the first lighting device and the second lighting device comprise a lighting unit, the invention also relates to a test light A module comprising at least one lighting unit. Background technique [0005] In such installations, the quality of the surface of the painted bodywork is checked, in particular visually, by testers. Imperfections in the surface cause a local distortion of the ...
