TECHNICAL FIELD
[0001] The utility model belongs to film fixture technical field, concretely relates to an insulating film arc ion plating film fixture. BACKGROUND
[0002] Among the common film preparation methods, magnetron sputtering, vacuum thermal evaporation and arc ion plating each occupies an important position. These methods have shown their unique advantages in different application scenarios. Among them, the arc ion plating method has become the preferred method in large-scale applications due to its large loading capacity, high efficiency and relatively low cost. In industrial production, especially in situations that require rapid and large-scale preparation of thin films, the arc ion plating method has shown unparalleled advantages with its high production capacity and economic cost-effectiveness.
[0003] However, when using the arc ion plating method to coat films on the surface of insulating materials, some technical problems are also encountered. During the coating process, the insulating material is clamped using a coating fixture, and the coating fixture is usually made of conductive metal. In the vacuum coating environment, there is a gap between the insulating film and the metal clamp. Ion beam current will deposit on the sample surface, accompanied by the accumulation of electric charge. If these accumulated charges are not discharged or neutralized in time, when they accumulate to a certain extent exceeding a certain threshold, they will cause electrostatic discharge. Electrostatic discharge not only causes sparks and electric shocks, but also introduces high temperatures in local areas, causing ablation of the workpiece, which in turn causes damage to the film material. At the same time, the micro-nano structure on the surface of the polymer is also prone to mechanical damage. This damage not only affects the quality and performance of the thin film, but also may have adverse effects on subsequent applications.
[0004] Therefore, how to effectively solve the problem of charge accumulation and mechanical damage of insulating films during arc ion plating has become a hot and difficult topic of current research. UTILITY MODEL CONTENTS

[0009] In some embodiments, the circumferential side of the elastic compression ring is arranged in the mounting space of the clamping plate assembly.
[0010] In some embodiments, the lower clamping plate is arranged as a solid lower clamping plate or a hollow lower clamping plate.
[0011] In some embodiments, a supporting plate is further arranged between the lower clamping plate and the elastic compression ring, and the supporting plate and the lower clamping plate are arranged in a spaced manner.
[0012] In some embodiments, the adjusting assembly comprises a suspended adjusting part, and the suspended adjusting part adjusts the spacing between the supporting plate and the lower clamping plate.

[0018] In summary, the utility model has at least the following advantages:
[0019] The insulating film arc ion plating fixture provided by this utility model involves placing the insulating material between the upper clamping plate and the elastic pressure ring. An adjusting component causes the upper clamping plate to press against the lower clamping plate, resulting in deformation of the elastic pressure ring. Under the action of the elastic pressure ring, the insulating material can be tightly connected to the upper clamping plate. This elastic deformation of the pressure ring creates a gapless connection between the insulating material and the fixture, thus preventing localized electric shocks to the insulating material and eliminating air layers between them. Therefore, it can be seen that the fixture of this application can completely eliminate gaps between the insulating material and the metal fixture, thereby preventing electrostatic discharge during the plating process. This effectively avoids electrostatic discharge and arcing caused by surface charge accumulation on the insulating material, prevents localized high-temperature ablation damage to the insulating material, and also prevents mechanical damage to the micro-nano structures on the polymer surface.
