Description

A kind of silver paste filter
Technical field
It the utility model is related to electronic silver paste manufacturing technology field, more particularly to a kind of silver paste filtration system.
Background technology
Electronic silver paste is due to being widely used in inductor, capacitor, solar cell with excellent electric property And the electronic component such as thin film switch, so electronic silver paste becomes the study hotspot of solar cell surface metallizing art. Electronic silver paste is generally made up of silver powder, glass dust, organic carrier and inorganic additive, and silver powder is conducting function phase, and glass dust is made To be bonded phase, inorganic additive serves as doping phase, and organic carrier then can be with the depth-width ratio of coordination electrode.
Production technology:The inorganic particles such as super fine silver powder, glass dust, inorganic additive is fully mixed according to certain mass ratio Close;The organic matters such as terpinol, benzene, castor oil, ethyl cellulose, citric acid tri butyl ester are modulated into organic carrier;By inorganic powder After body and organic carrier are sufficiently mixed, silver paste is ground with three-roll grinder, silver paste be ground to certain fineness with It is exactly gained final products afterwards.
In super fine silver powder preparation process, due to the surface charge interaction between silver powder particles, silver powder can be produced Aggregate, so as to form the larger Argent grain of many particle diameters;These aggregates, can also be because of organic due in silver paste process for preparation The interaction of carrier and Argent grain surface is reunited again, so increasing the fineness of silver paste;And produced in silver paste printing process The consequences such as void print, broken string.
The content of the invention
The technical problems to be solved in the utility model is:A kind of silver paste filter is provided, improves the fineness of silver paste.
The technical solution of the utility model is as follows:
A kind of silver paste filter, including silver paste lautertuns, silver paste lautertuns side are connected with the first vavuum pump, the silver It is motor of the lower end with agitating paddle to starch above lautertuns, is followed successively by silver paste lautertuns below agitating paddle and from top to bottom Screen, mixing roll and funnel, funnel exit are provided with discharge gate;
It is connected on the outside of silver paste lautertuns with sonic oscillation machine;
Silver paste filters trench bottom and feed back pipeline communication, and the second vavuum pump is provided with the pipeline of feed back pipeline, and The port of export of feed back pipeline is located above agitating paddle.
The sieves is parallel with the Plane of rotation of agitating paddle blade, and sonic oscillation machine is located at sieves and agitating paddle Blade Plane of rotation is on the outside of the face of cylinder of end face.
Connected between first vavuum pump and silver paste lautertuns by PA tube.
Valve is provided with the PA tube.
Silver paste lautertuns, sieves and agitating paddle are stainless steel.
Funnel section in silver paste lautertuns is tapered.
Motor of the lower end with agitating paddle is connected with hydraulic elevating platform.
Operation principle of the present utility model is as follows:The valve of silver paste filtering trench bottom is closed, and the first vavuum pump is opened, to silver Slurry lautertuns is vacuumized, and starts motor, drives agitating paddle to rotate, while opens sonic oscillation machine, opens grinding motor belt motor Dynamic mixing roll is rotated, and under vacuum action and the pressure of agitating paddle, silver paste is filtered by sieves, in sonic oscillation machine Under concussion effect, the aggregate in silver paste is opened, while ultrasonic vibration acts on, and is also beneficial to the group got lodged in filtering sieve aperture Aggressiveness particle is pushed open, is prevented aggregate particle from being blocked sieve aperture is filtered, is improved the filter efficiency of silver paste, the silver flowed down from sieves Slurry can fall on mixing roll, after grinding, can improve silver paste fineness;Complete to open discharge gate after once filtering, Silver paste all flows to filtering trench bottom, when filtering for the second time, starts the second vavuum pump, and the silver paste pump that silver paste is filtered to trench bottom arrives Filter again on silver paste lautertuns top.After filtering, silver paste can improve point in its fineness, and silver paste printing process Resolution.
The utility model obtains pressure, coordinates the vacuum of vavuum pump to make by motor driven agitating paddle, blade agitation silver paste With realizing the filtering of silver paste by sieves, further the grinding by mixing roll and multiple times of filtration, mixing roll improve silver paste Fineness, the second vavuum pump realizes the automatic cycle feeding of silver paste filter process, finally improves the fineness of silver paste.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Brief description is made to specific embodiment of the present utility model below in conjunction with the accompanying drawings.
As shown in figure 1, be silver paste filter of the present utility model, including silver paste lautertuns 2 and with silver paste lautertuns 2 one The motor 4 of oar (agitating paddle 3) is scraped on the first connected vavuum pump 1 of side, the top of silver paste lautertuns 2 equipped with band, in silver paste lautertuns 2 and In scraping for motor 4 sieves 5 is housed below oar, the lower section of sieves 5 is mixing roll 10, and mixing roll 10 passes through installed in lautertuns 2 Outside grinding motor 11 drives, one group of mixing roll 10 two piece, using stainless steel roller;It is also equipped with surpassing outside silver paste lautertuns 2 Sound oscillation machine 6, the installation site of supersonic oscillations machine 6 will ensure what its sphere of action was formed included in agitating paddle 3 and sieves 5 In cylindrical surface (i.e. the scope of ultrasonic vibrator effect);By with valve 8 between first vavuum pump 1 and silver paste lautertuns 2 PA tube 9 connects.Silver paste lautertuns 2, sieves 5, agitating paddle 3 are all that acid-resistant stainless steel is made.Motor 4 and agitating paddle 3 are logical Cross hydraulic elevating platform to fix, the installation and removal of equipment can be facilitated, can also adjust the blade of agitating paddle 3 and sieves 5 it Between gap, so as to adjust pressure.
