Description

Technical Field

[0001] The utility model relates to the technical field of thin film capacitors, in particular to a glue filling device for thin film capacitors which is convenient for quantitative addition. Background Technique

[0002] A thin film capacitor is a capacitor with excellent performance, such as being non-polar, having a very high insulation impedance, excellent frequency characteristics, and very small dielectric loss. During its production process, a resin and other liquid composites need to be filled into it through a glue filling device for encapsulation to strengthen the integrity of the capacitor and improve its resistance to external impacts and vibrations. During use, it is generally not convenient to quantitatively add and fill the thin film capacitor body, and it is not convenient to remove air bubbles by vibration after filling the thin film capacitor body, making it difficult to achieve good glue filling quality for the thin film capacitor body. Moreover, it is not convenient to effectively fix the thin film capacitor body with different diameter specifications during glue filling, which may cause the thin film capacitor body to shift and loosen, resulting in poor glue filling effect. In addition, the colloid inside the storage tank cannot be fully and evenly stirred and the inner wall of the storage tank cannot be cleaned, which may cause glue blocks to adhere to the inner wall of the storage barrel, reducing the service life of the storage barrel. Therefore, we propose a glue filling device for thin film capacitors which is convenient for quantitative addition to solve this problem. Content of the Utility Model
