Description

Liquid material extrusion method and device

The present invention relates to an extrusion method and apparatus, and more particularly to a liquid material extrusion method and apparatus for a liquid material having a viscosity and a liquid material extruded in two stages by an impact member and an extrusion member.

According to the extrusion of a generally viscous liquid material, it is often provided by a plunger extrusion or a screw extrusion method, and the viscosity of the viscous liquid material used in the former is low, and the latter is used in a high viscosity. The viscous liquid material; in the former case, because of the low viscosity, the high-speed jetting is often carried out in a non-contact manner with the object to be adhered in the extrusion mode, and the high-speed re-extrusion is performed in the prior art. The spring is matched with a plunger having a pneumatic piston above, and after the pneumatic piston is moved up by the pneumatic thrust, the air pressure is released, so that the spring is driven by the compression force to drive the plunger to squeeze the adhesive liquid downward.

Since high-speed liquid material extrusion is gradually required, a method and apparatus for separating a pneumatic piston from a plunger into an impact member and an extrusion member, and then striking the impact member against the extrusion member to extrude the liquid material are developed, for example, US6267266 "non-contact liquid material dispenser having a bellows valve assembly and method for ejecting liquid material onto a substrate", which impacts an extruded member with an impact member linked by a pneumatic piston, the extruded member being a tubular body Connecting and interlocking a liquid material input pipe from the liquid storage cylinder, so that the liquid material is input into the tube body of the extrusion member, and is filled in a flexible member having an extrusion pipe under the extrusion member, and the impact member is pressed by the extrusion member After the impact, the extruded member re-extrudes the flexure to make the flexure empty Under the restriction, the thickness is reduced to press the liquid material in the extruded pipe, and the liquid material is extruded.

In addition, the TW I428187 "Liquid Discharge Device and Liquid Discharge Method" patent also separates the pneumatic piston from the plunger into an impact member and an extrusion member, but it elongates the extrusion member and passes through the impact member for the upper portion. A fine adjustment mechanism is used to adjust the upper limit positioning of the extrusion member, and between the abutting portion of the extrusion member and the liquid chamber, another fine adjustment mechanism is provided to adjust the position under the extrusion member.

CN103502781 "force amplification drive system, spray distributor, and method for distributing fluid", which are respectively subjected to the intake and exhaust operations of the upper and lower ends of the piston, and drive the impact member to repeatedly impact the extruded member, and in the liquid chamber A stop member is provided to limit the upper limit of the extrusion member, and the distance over which the extrusion member is moved is positioned.

In the TW M409893 "dispensing machine" patent, a first striker is coupled to the output shaft of the drive mechanism by a one-way magnetic attraction of an electromagnet, and the first striker is reversed in response to the insertion of an elastic member. The restoring force mode forms a repeated power, and then the first striker strikes the second striker, and the bottom end of the second striker is extruded on the liquid material at the nozzle.

However, the extrusion member of the prior art US Pat. No. 6,267,266 is a tubular body which connects and interlocks the liquid material input pipe from the liquid storage cylinder, so that each displacement of the extrusion member is accompanied by the interlocking liquid material output pipe at high speed and high frequency. Repeated displacement has an effect; while the extruded member of TW I428187 is in liquid contact with the liquid chamber wall in a non-contact manner, it is necessary to limit the upper and lower limits of the extruded member, and is not suitable for contact type; The pneumatic piston and the plunger are separated into an impact member and an extruded member, but the driving force of the impact member is still derived from the pneumatic piston and the spring, and the driving force for the repeated displacement output of the high speed and the high frequency is still insufficient! And the impact member adopts the tubular body center The way of extruding the member also increases the resistance of the sliding displacement; CN103502781 adopts a stopping member in the liquid chamber for limiting the upper limit positioning of the extruded member, and the displacement of the stopping member in the liquid chamber will be hindered by the liquid material. Stagnation, and it is easy to squeeze the liquid material through the shaft seal gap during the upward movement of the stopper to form a leak! In addition, although the TW M409893 adopts the magnetic attraction mode of the electromagnet, only the one-way magnetic attraction forms the downward driving force, and the repeated upward driving force must come from the action of increasing the first striker and the elastic member, not only the interlocking structure is complicated, and it is repeated. The speed and frequency of the inching are still limited by the innate confinement of the elastic member and the transmission resistance between the first striker, and the first striker is directly contacted by the inner ring bushing of the electromagnet as the upper limit positioning, and the contact will cause the electromagnet Loss, so there is still room for improvement!
