Problems solved by technology

In the prior art MLCC casting process, the manufacturing process is to pass the ceramic slurry through the sprue of the casting machine, so that it is coated on the winding polyester film (PET), thereby forming a layer of uniform slurry Thin layer, and then through the hot air zone to volatilize most of the solvent in the slurry, and obtain a ceramic membrane after drying, but use a scraper to control the thickness of the film when scraping, and now use a single-layer scraper for the blade. Higher requirements, The flatness of the blade is required to be very high, which makes the manufacturing cost of the scraper relatively high

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings by means of specific embodiments:

[0012] Such as figure 1 The ceramic diaphragm scraping device shown includes a worktable 1, a transmission belt 2 and a scraping film substrate 4, the scraping film substrate 4 is fixed on the transmission belt 2, and both ends of the transmission belt 2 are fixed on the worktable 1 by rotating rollers. A film scraping device is erected above the conveyor belt 2. The film scraping device includes a material box 5, a scraper bracket 6 and a scraper 7. The scraper bracket 6 is fixed on one side of the material box 5, and the bottom edge of the other side of the material box 5 is connected to the scraping film substrate 4. For contact, a plurality of scrapers 7 are fixedly arranged under the scraper bracket 6 , the lower ends of the blades of the scrapers 7 are flush, and a screw regulator 8 is arranged between the scraper bracke...

Abstract

The invention relates to the field of electronic material manufacture and concretely relates to a ceramic membrane blade-coating device. The device comprises a workbench, a transmission belt and a membrane blade-coating base plate. The membrane blade-coating base plate is fixed to the transmission belt. Two ends of the transmission belt are fixed to the workbench through rotating rollers. A membrane blade-coating device is erected above the transmission belt. The membrane blade-coating device comprises a material tank, a scrapping blade support and scrapping blades. The scrapping blade support is fixed to one side of the material tank and the bottom edge of the other side of the material tank contacts with the membrane blade-coating base plate. The multiple scrapping blades are fixedly arranged below the scrapping blade support. Lower ends of the edges of the scrapping blades align. Spiral regulators are arranged between the scrapping blade support and the scrapping blades. The device is used for ceramic membrane manufacture and realizes finish machining blade effects only through the common scrapping blades.

Description

technical field [0001] The invention belongs to the field of electronic material manufacturing, in particular to a ceramic diaphragm scraping device. Background technique [0002] Ceramic diaphragm is a commonly used material for manufacturing electronic components. Because it has a high anti-breakdown voltage level, it is used to manufacture ceramic electronic components, especially the manufacture of ceramic capacitors (MLCC for short); firstly, the ceramic diaphragm Stacked in a cross-displaced manner to form blocks, cut and separated into ceramic green bodies, and then sintered at a high temperature to form a ceramic body, thereby forming a structure similar to a monolith, and then preparing three layers at both ends of the ceramic body Or multi-layer metal external electrodes (terminal electrodes) form MLCC finished products. In addition to the common characteristics of capacitors "blocking direct traffic", MLCC also has the characteristics of small size, large specifi...
