Industrial radiographic films, as the visual carriers of test results, directly determine the accuracy and reliability of defect identification through their developing and fixing quality. The film processing holder, as the core tool for carrying the film and assisting in the developing and fixing process, plays a decisive role in the film processing effect through its design and performance. However, while traditional film processing technologies are mature and widely used, they still have some minor flaws that affect the quality and efficiency of testing work to some extent.

[0003] On the one hand, traditional film developing clamps lack effective protective measures during film retrieval. When operators use inverted developing clamps to remove film, the film often slips, comes into accidental contact, or is damaged due to improper operation, resulting in dust accumulation, fingerprints, or creases on the film surface, affecting the clarity and integrity of the film. These problems not only increase the rework rate and testing costs but may also delay the project schedule, negatively impacting quality control and progress management in industrial production.

[0004] In summary, the development of a film processing clamp for industrial X-ray inspection that can fix the position of the film when the film is picked up by the inverted control film processing clamp or can completely realize the film picking up by the upright film processing clamp without the inverted control method has become an urgent need to improve the quality and efficiency of industrial X-ray inspection. The film processing clamp for industrial X-ray inspection of the present invention has emerged in response to this background. Utility Model Content
