Abstract
The present invention provides a kind of silk-screen printing techniques for high-temperature co-fired ceramics, can increase inner side wall of through hole printing, filling perforation efficiency.Its technical solution is such that a kind of silk-screen printing technique for high-temperature co-fired ceramics, it is characterized by: itself the following steps are included: 1, green blank is placed on the table top of screen-printing machine, and by the first vacuum port and green blank through-hole alignment on wire mark machine table top；2, vacuum evacuation device is opened, adsorbs green blank using the second vacuum port on table top, and pull of vacuum is transferred to the through-hole of green blank by the first vacuum port；3, silk-screen printing is carried out to green blank by screen-printing machine.
Description
Technical field
The present invention relates to high-temperature co-fired ceramics processing technology field, specially a kind of screen printing for high-temperature co-fired ceramics
Dataller's skill.
Background technique
When making ceramic component, need when high-temperature co-fired ceramics is after the completion of production, in one layer of slurry of its surface printing,
Traditional printing is applied pressure to slurry by scraper plate and covered the surface of potsherd by be allowed it by the way of silk-screen printing, but
It is that when the inner sidewall for needing that slurry is made to be printed onto the through-hole on some potsherds or ought need to the through-hole on some potsherds
When carrying out filling perforation using slurry, covering or filling perforation are carried out using traditional silk-screened method, the dynamics of scraper plate extruding slurry is not
Foot, filling perforation slurry cannot effectively pass through silk screen, cause filling perforation is discontented, inner sidewall covering not exclusively, need repeated multiple times printing
It can make it that inner side wall of through hole be completely covered or fill up, low efficiency is very inconvenient.
Summary of the invention
In view of the above-mentioned problems, can increase the present invention provides a kind of silk-screen printing technique for high-temperature co-fired ceramics
Inner side wall of through hole printing, filling perforation efficiency.
Its technical solution is such that a kind of silk-screen printing technique for high-temperature co-fired ceramics, it is characterised in that: it is wrapped
Include following steps:
1, green blank is placed on the table top of screen-printing machine, and the first vacuum port on wire mark machine table top is led to green blank
Hole alignment；
2, vacuum evacuation device is opened, adsorbs green blank using the second vacuum port on table top, and pull of vacuum is passed through first
Vacuum port is transferred to the through-hole of green blank；
3, silk-screen printing is carried out to green blank by screen-printing machine.
It is further characterized by:
The distance between silk screen and green blank of screen-printing machine are 1mm-3mm；
It is 0.18MPa-0.25MPa by the pressure that scraper plate applies when silk-screen printing；
When silk-screen printing, the movement speed of scraper plate is 10mm/s-25mm/s；
When silk-screen printing, the tilt angle of scraper plate is 60 degree of -80 degree.
After with such a structure, when carrying out silk-screen printing, in the through-hole passed through on green blank, enable to
Slurry on the basis of the active force of original scraper plate by pull of vacuum, to make slurry be easier in access aperture, to increase
Inner side wall of through hole printing and filling perforation efficiency.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
A kind of silk-screen printing technique for high-temperature co-fired ceramics as shown in Figure 1 comprising following steps: 1, by high temperature
The integration of common burning porcelain green is pressed into block by isostatic pressing process to form suitable green blank 1, the thickness of green blank 1
For 0.1mm-0.5mm, green blank 1 is placed on the table top 2 of screen-printing machine, and by the first vacuum port 3 on wire mark machine table top 2
It is aligned with 1 through-hole 4 of green blank；
2, vacuum evacuation device (not shown) is opened, adsorbs green blank 1 using the second vacuum port 5 on table top 2, and will be true
Suction power is transferred to the through-hole 4 of green blank 1 by the first vacuum port 3；
3, by screen-printing machine to green blank 1 carry out silk-screen printing, wherein between the silk screen 6 and green blank 1 of screen-printing machine away from
It is 0.18MPa-0.25MPa by the pressure that scraper plate 7 applies when silk-screen printing from for 1mm-3mm；When silk-screen printing, scraper plate 7
Movement speed be 10mm/s-25mm/s；When silk-screen printing, the tilt angle of scraper plate 7 is 60 degree of -80 degree.
After with such a structure, when carrying out silk-screen printing, in the through-hole 4 passed through on green blank 1, it can make
Slurry 8 is obtained on the basis of the active force of original scraper plate 7 by pull of vacuum, so that slurry 8 is made to be easier to enter in through-hole 4,
To increase the printing of 4 inner sidewall of through-hole and filling perforation efficiency.
The table top 2 for the screen-printing machine directly bought in the market is opened up first according to the through-hole 4 on green blank 1 by the present apparatus
Vacuum port 3, and the second vacuum port 5 for adsorbing green blank 1 is opened up on table top 2,2 bottom of table top is equipped with cavity (in figure
It is not shown), cavity covers all the first vacuum port 3 and the second vacuum port 5, cavity and is connected with vacuum evacuation device, specially very
Sky pump, pumps cavity vacuum by vacuum pump, so that suction be passed from cavity to the first vacuum port 3 and the second vacuum port 5
It passs.
More than, it is merely preferred embodiments of the present invention, but scope of protection of the present invention is not limited thereto, it is any
It is familiar with the people of the technology within the technical scope disclosed by the invention, any changes or substitutions that can be easily thought of, should all cover at this
Within the protection scope of invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
