Description

Technical Field

[0001] The utility model belongs to the technical field of diaphragm position adjustment, in particular to a downward pressing structure and ceramic capacitor processing equipment. Background Art

[0002] The manufacturing process of multi-layer ceramic chip capacitors (MLCC) includes multiple steps. Before cutting, it mainly includes the following processes: batching, casting, printing, lamination, capping and lamination. Among them, the lamination stage involves laminating the ceramic diaphragms with printed inner electrodes according to the designed misalignment requirements to form the MLCC bar. The entire production process is carried out step by step, layer by layer, and finally the manufacturing of MLCC is completed.

[0003] One of the steps in the lamination process is to laminate the protective layer and the dielectric layer to form a block. In the process of laminating the dielectric film, a downward pressing structure is required. The downward pressing structure moves the multiple rectangular dielectric membrane units attached to the membrane strip to the upper pressing platform in sequence, and stacks the latter dielectric membrane unit on the previous dielectric membrane unit on the upper pressing platform. When the two dielectric membrane units are stacked, there is a position deviation in the vertical direction, or after long-term use, the downward pressing structure will be worn, resulting in errors. This reduces the accuracy of the stacking of the dielectric membrane units and finally reduces the accuracy of the dielectric layer. Utility Model Content
