【摘要】：随着我国的石材需求量和供应量日益增多，人们对石材的数量和质量要求不断提高，而在石材表面涂覆这方面，多数企业仍停留在人工涂覆的加工方式，不仅费时费力而且无法保证涂覆的质量。此种方法无法使石材表面各部分的涂覆厚度保持均匀，石材表面缺陷中的水汽将存于涂料之下，易受温度等影响破坏涂覆表面，需定期维护。因此本课题实现了石材在真空状态下自动涂覆，并使涂覆的高分子薄膜材料在压差作用下浸入石材本体空隙和缺陷中，提高石材表面涂覆质量和生产效率。 根据石材真空涂覆装置的设计要求，对设备的各个功能机构提出多种设计方案，并进行分析和选择，对各种设计方案的优缺点进行比较，按照一定的选用标准，综合考虑各种设计方案的特点，选择最佳方案。 根据选定的各部件的最优方案，，对真空涂覆装置进行三维建模。使用有限元分析软件进行静力学分析，模态分析和瞬态分析得出了最大回气速率。为消除真空涂覆装置的结构缺陷提供理论依据并进行改进设计。 根据对具体的工作条件和方式设计真空室结构并选用合适的密封方案，包括真空槽，真空泵，吸尘器和真空计的选型，电极的引入等。通过对不同开门方式的比较选用合理的开门方式和气缸。
[Abstract]:With the increasing demand and supply of stone in our country, the quantity and quality of stone are increasing. However, in the aspect of stone surface coating, most enterprises still stay in the processing mode of manual coating, which is not only time-consuming and laborious, but also can not guarantee the quality of coating. This method can not make the coating thickness of each part of the stone surface uniform, the water vapor in the stone surface defects will be stored under the coating, easy to be affected by temperature to destroy the coating surface, it needs to be maintained regularly. Therefore, this paper realizes the automatic coating of stone in vacuum, and immerses the coated polymer film material into the gaps and defects of stone body under the action of pressure difference, so as to improve the coating quality and production efficiency of stone surface. According to the design requirements of stone vacuum coating device, a variety of design schemes are put forward for each functional mechanism of the equipment, and the advantages and disadvantages of each design scheme are compared. According to certain selection standards, the characteristics of various design schemes are comprehensively considered, and the best scheme is selected. According to the optimal scheme of each component, the vacuum coating device is modeled in three dimensions. The maximum return rate is obtained by static analysis, modal analysis and transient analysis with finite element analysis software. It provides a theoretical basis for eliminating the structural defects of the vacuum coating device and improves the design. According to the specific working conditions and methods, the structure of vacuum chamber is designed and the suitable sealing scheme is selected, including the selection of vacuum tank, vacuum pump, vacuum cleaner and vacuum gauge, the introduction of electrode and so on. Through the comparison of different opening modes, the reasonable opening mode and cylinder are selected.
