[0029] In the field of aircraft non-destructive testing technology, the excess control and the missing rivet inspection of the aircraft wing area or the flat tail area are usually carried out by X-ray detection. For example, in the X-ray detection of the aircraft wing, due to the limited range of the X-ray emitter, and in order to avoid the overlapping of the X-ray shooting area between the adjacent two areas, the shooting of the several spaced areas is usually carried out in two batches.
[0030] In the prior art, the film needs to be manually pasted on the several spaced areas on the wing before the first X-ray detection, and then the first X-ray shooting is carried out. After the first X-ray shooting, the film needs to be manually pasted on the remaining several spaced areas again, and then the shooting is carried out again. During the first X-ray shooting, the pasting personnel needs to leave the shooting space to wait, and then paste the film after the first shooting is completed, which will cause a blank operation time, consume time and effort, and is low in efficiency. The splicing of the subsequent X-ray images is also difficult to complete, and the film pasted on the wing by the manual operation is easy to cause image distortion due to the deviation of the film placement position, which is more inconvenient for the splicing of the entire wing X-ray image.
