Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing equipment, in particular to an ink return knife structure and MLCC printing equipment. Background Art
[0002] At present, driven by fields such as 5G communications, smart phones and new energy vehicles, the development of the electronic information industry is thriving and has become an important pillar of the economic market.
[0003] Among them, multilayer ceramic capacitors (MLCCs)—comprising ceramic dielectric diaphragms with printed electrodes (inner electrodes) stacked in an offset arrangement, sintered once at high temperature to form a ceramic chip, and then sealed with metal layers (outer electrodes) at both ends, creating a monolithic structure, hence the name monolithic capacitor—have the largest market share among passive electronic components and have become a key product requiring breakthroughs in key technologies for technological innovation. MLCCs, with their advantages of high capacitance, small size, low cost, and high reliability, are widely used in automotive electronics, electrical control, power grid frequency modulation, instrumentation, aerospace, and other fields, earning them the nickname "the rice of the electronics industry."
[0004] In the existing technology, the main process flow of MLCC is: batching → casting → printing → lamination → lamination → cutting → debinding → sintering → chamfering → end sealing → end burning → end treatment → electrical performance testing → qualified, packaging and warehousing.
[0005] Among them, the printing equipment is mainly used in the production of MLCC to print the internal electrode pattern on the ceramic cast film, dry the electrode pattern, and finally roll the ceramic cast film with the electrode pattern (or called the printed ceramic medium) into a neat roll.
[0006] In addition, the printing equipment is mainly composed of a printing system, a drying system, a heating system, a control system, etc.; its working principle is to roll materials such as printing ceramic media into a roll, and then place it on the printing platform of the printing equipment; the printing equipment can evenly apply the printing paste (in liquid state) made of metal electrode material on the above-mentioned printing ceramic medium, thereby forming a layered structure with a preset thickness; after that, it is processed through a drying system and a heating system to make the liquid printing paste evaporate and dry, and finally rolled into a neat roll.
[0007] Generally speaking, printing equipment mainly uses a scraper structure and an ink return knife structure to evenly apply the printing paste on the printing ceramic medium. However, the traditional ink return knife structure still has some defects:
[0008] (1) The conventional ink return blade structure easily pushes the printing paste to both sides of the printing platform (or printing screen) during the printing ink return coating process (i.e., the conventional ink return blade structure easily causes the printing paste to overflow).
[0009] (2) Since the traditional ink return knife structure easily causes the printing paste to overflow, it will lead to the accumulation of printing paste. The long-term accumulation will cause the printing paste to volatilize, thereby increasing the viscosity of the printing paste, and ultimately affecting the thickness of the layered structure coated on the printing ceramic medium.
[0010] (3) If too much printing paste is accumulated on both sides of the printing screen, it will cause the layered structure coated on the printing ceramic medium to diffuse locally.
[0011] (4) Since the traditional ink return knife structure is prone to causing overflow of printing paste, the printing equipment needs to be shut down before the operator can manually handle the printing paste accumulated on both sides of the printing screen to the printing area. The equipment shutdown not only increases the time cost of printing, but also easily causes the layered structure coated on the printing ceramic medium to diffuse. Utility Model Content
