Abstract
The utility model relates to a high viscosity is plunger case for electronic paste, it includes that 304 or 316L stainless steel cylinder, cylinder internally mounted has the piston, and cylinder barrel tail end installs the end cover, and the mid portion of end cover has a through -hole, and the through -hole passes through the hose connection sealing medium and breathes the bucket. The piston rod passes the end cover hole, and one end is fixed with the piston body. The utility model provides a plunger case is owing to the sealed of medium liquid that has certain viscosity seals up more than easy realization of air to greatly reduced the wearing and tearing of part.
Description
One, technical field
The present invention relates to a kind of high viscosity electron paste plunger case, is the crucial power executive component of liqued plunger filler, is suitable for but is not limited to high viscosity electron paste field.
Two, background technique
Along with the progress increasingly of electronic technology, all kinds of electron paste increases day by day in the application in the field such as thick film, photovoltaic.For convenience of using, electron paste must through packing before dispatching from the factory, client is supplied to the packaged form of bottle, and electron paste often has high thixotropic, full-bodied characteristic, so the plunger case that uses carries out filling and quantitative more in industry as power executive component, but the electron paste due to the overwhelming majority contains a certain proportion of glass powder, thus to the cylinder barrel of plunger case, piston, the serious wear such as Sealing, very easily cause seal failure, faults such as leakage thus have a strong impact on filling accuracy, and due to the high pressure of the larger degree of vacuum of suction process and binder process will be realized, high to the requirement on machining accuracy of composition component, thus manufacture and maintenance cost high.
Three, summary of the invention
The present invention relates to a kind of high viscosity electron paste plunger case, it improves to form on the basis of conventional post plug cylinder, plunger case comprises stainless steel cylinder barrel, cylinder barrel inside is provided with piston, cylinder barrel end is provided with end cap, and the intermediate portion of end cap has a through hole, and through hole connects sealing medium breath tank by flexible pipe, piston rod is through end cap endoporus, and one end and piston body are fixed.
Described inner wall of cylinder, through fine gtinding, has higher surface finishment, greatly reduces parts depreciation.
Described piston rod is through end cap endoporus, and one end and piston body are fixed.The media fluid with certain viscosity (5000-10000 centipoise) is filled in cylinder barrel during use between piston and end cap, during action, cylinder barrel volume between piston and end cap changes, media fluid is extruded by flexible pipe or sucks, cylinder barrel space in course of action between piston and end cap is full of media fluid all the time, and isolated air realizes secondary seal.
Described cylinder barrel inside is provided with piston, realizes the motive sealing with cylinder barrel by three y-type seal rings,
Described cylinder barrel end is provided with end cap, and end cap outer is provided with two O RunddichtringOs and realizes the static seal with cylinder barrel.
Described end cap endoporus is provided with a y-type seal ring and realizes the motive sealing with piston rod, and the intermediate portion of end cap has a through hole, and through hole connects sealing medium breath tank by flexible pipe.
Compared with traditional high viscosity electron paste plunger case, present invention employs there is certain viscosity media fluid as secondary seal, isolated air can be played, lubrication and seal circle, the effect of compensating piston wearing and tearing, extend the working life of high viscosity electron paste plunger case greatly, because the sealing with the media fluid of certain viscosity easily realizes sealing more than air, the requirement on machining accuracy of composition component is reduced greatly, thus manufacture and maintenance cost can decline to a great extent, simultaneously due to the existence of end cover designs, the effect of support can be played to piston rod, piston concentricity in running, stability significantly improves.
Four, accompanying drawing explanation
