Description

Technical Field

[0001] The utility model relates to the structural technology field in the machinery industry, in particular to a full-automatic sheet cutting and pressing machine with a casting connection structure in the production process of electronic components. Background Art

[0002] In the production process of electronic components, such as chip multilayer ceramic capacitors (MLCC), chip multilayer inductors (MLCI), etc., it is often necessary to cut ceramic film sheets into certain shapes / sizes and stack them on an iron carrier plate according to the product design requirements, relying on the viscosity of the ceramic film sheets themselves and the pressure of a hot press to form an integral body, which is simply called an electrode bar block. Chinese Patent CN202220150397.2 is only applicable to the process of electrode bar blocks (rather than protective layer bar blocks) that require printing electrode patterns on dielectric film sheets, and must be installed in combination with a screen printing machine and a mesh belt drying furnace. That is, print electrode patterns on the bar block with a pre-laid bottom protective layer → dry the electrode patterns (referred to as drying the bar) → add ceramic dielectric film sheets to the bar block (referred to as lamination) → heat and press (referred to as hot pressing) → print electrode patterns → dry the bar → laminate → hot press, and repeat this process to obtain an inner electrode bar block. The film sheets used for lamination are provided by a material box with pre-isolated lamination by manual, and the film sheets need to be separated from the release paper before lamination and heat pressing. It cannot meet the preparation of protective layer bar blocks, nor can it be connected to the back end of a casting machine for supporting installation, nor can it perform online automatic cutting, lamination / stacking, and heating and pressing; a special cutting, laminating, and box loading machine that can be installed in combination with the casting machine needs to be equipped, which greatly increases the production cost of enterprises and reduces production efficiency.
