Description

Soft X-ray emission device for stripping adhesive tape Technical Field The invention relates to the technical field of X-ray sources, in particular to a soft X-ray emission device for a stripping adhesive tape. Background With the rapid development of material science, biomedical and industrial nondestructive testing techniques, there is an increasing demand for miniaturized, low power consumption and portable X-ray sources. Current small X-ray sources are mostly based on hot cathode emission or other field emission mechanisms, e.g. a hot cathode X-ray tube generates electrons by heating a filament and bombarding an anode target under acceleration of a high voltage electric field (typically several tens to hundreds of kilovolts) to generate X-rays. However, such devices have many limitations, firstly, the generation of high-energy electron beams requires a large and expensive high-voltage power supply system and a complex insulation protection structure, secondly, the hot cathode is high in power consumption and serious in heat generation during operation, requires an additional cooling system, and is long in preheating starting time, and is difficult to meet the requirement of quick response, and furthermore, although the field emission X-ray source based on Carbon Nanotubes (CNTs) reduces power consumption to a certain extent, the core of the field emission X-ray source still depends on a high-voltage accelerating field, and long-term stability of cathode materials under a strong field is still a technical bottleneck. In contrast, the conversion of mechanical energy into X-rays based on triboelectric effect provides a new technical path for solving the above problems. However, existing triboelectric X-ray emitting devices are in the laboratory principle verification phase, and there are still significant drawbacks and shortcomings in engineering applications: The output stability is poor and the regulation is difficult, the lack of a fine regulating mechanism for the tension of the adhesive tape, the output fluctuation caused in the peeling process is difficult to eliminate only by simple motor driving, and the X-ray emission is unstable.
