Description

Technical Field

[0001] The present invention relates to the technical field of MLCC ceramic capacitor printing, in particular to an MLCC ceramic capacitor laminating machine. Background Art

[0002] MLCC ceramic capacitors are also called chip capacitors. Their production includes stacking the printed electrode layers with the number of layers designed for the upper and lower blank layers, and pressing them at high temperature and high pressure to avoid stratification, thereby forming the desired product. The ceramic film of this type of ceramic capacitor is relatively thin and light. The ceramic film pressing process of the laminating machine currently developed in the market often causes bubbles, dislocation and false pressing. The reasons for this phenomenon are the insufficient precision of the pressing unit and the instability of the previous process steps. The electrode film mechanism and blank film mechanism of the laminating machine have deviations in accuracy during the feeding process, or the parallel accuracy of the stripping plate and the gold mold plate has deviations, which completely affects the subsequent stripping process and the accuracy of the pressing and laminating. The laminating machine on the market is a sheet-type laminating machine. This operation process is cumbersome, and in order to meet mass production and keep up with the production schedule, it is often necessary to increase the equipment volume and process steps.
