Definitions
- the present invention relates to a liquid dispenser used to discharge a small amount and / or high frequency of electronic materials, adhesives, and other liquid materials having a paste shape, a cream shape, or the like, which are filled in a syringe.
- the present invention relates to a plunger for a syringe suitable for always accurately discharging a body under an appropriate pressure.
- the liquid dispenser supplies a pressurized air as an air pulse to a syringe filled with a liquid material, and presses the liquid material with the air pulse, thereby finely dispensing a predetermined amount of liquid from a needle attached to the tip of the syringe.
- It is a device widely used in the electronic industry for the purpose of volume discharge and / or high frequency discharge.
- the liquid level in the syringe will decrease every time the liquid is ejected.
- the amount of liquid adhered to the syringe increased, only the liquid level at the center of the syringe dropped particularly.
- a plunger or the like having two upper and lower flanges is arranged on the peripheral surface of the bottomed cylinder, and the plunger presses the entire surface of the liquid material almost uniformly, and Attempts were made to prevent the liquid material from adhering to the syringe wall.
- the suction air increases, the pressure of the pressurized air supplied to the plunger in a pulsed manner is transmitted to the liquid material through the suction air that undergoes compression deformation.
- the transmission speed to the liquid material is slowed down, and the discharge amount of the liquid material discharged from the needle fluctuates, and it is possible that the liquid material is not discharged at all.
- the plunger includes a tapered tip portion 1 having a rear end portion 4 having an outer diameter somewhat smaller than the inner diameter of the syringe, and a rear end portion 4 which is continuous behind the tapered tip portion 1.
- a smaller-diameter trunk portion 2 having a smaller diameter, a tubular portion 3 continuing further behind the small-diameter trunk portion 2 and having a maximum outer diameter larger than the inner diameter of the syringe, and a tubular portion 3 extending in the axial direction of the syringe. It is provided with a slit 7 for dividing into a plurality of blade members 8.
- the following proposals still need to be solved for this improvement proposal.
- the contact between the plunger and the inner wall surface of the syringe is caused by the contact between the cylindrical part 3 provided at the upper part of the plunger and the rear end part 4 of the tapered tip part 1 provided at the lower part of the plunger.
- the rear end 4 and the inner wall of the syringe to allow the passage of solids that may be contained in the liquid material. It cannot be completely prevented from tilting.If such a tilt occurs, the maximum outer diameter of the plunger will not evenly contact the inner wall of the syringe, Since the plunger thrust by the pressurized air acts not only downward but also on the inner wall of the syringe, there was a problem that the plunger could not operate smoothly.
- the cylindrical portion 3 provided on the upper portion has a relatively thin cylindrical shape, but the tapered tip portion 1 provided on the lower portion and the small-diameter body portion are provided.
- 2 has a central hole 9 in its axial direction, but has a relatively thick wall as a whole, so it is used for discharging a small amount of medium-viscosity liquid material with a relatively large specific gravity.
- a relatively small specific gravity such as water or alcohol.
- An object of the present invention is to provide a syringe plunger for a liquid dispenser that solves all the problems of the prior art as described above.
- the purpose of the present invention is to provide a plunger capable of always ensuring a smooth operation even when discharging a small amount of liquid material having a small specific gravity.
- the present inventor has arrived at the present invention having the following content as a gist. That is, the syringe plunger of the liquid dispenser of the present invention has a tapered tip portion whose rear end has an outer diameter somewhat smaller than the inner diameter of the syringe, and a rear end continuous with the rear end of the tapered tip portion, and It has a maximum outer diameter substantially equal to the inner diameter of the syringe at its rear end, and is connected to an open cylindrical body and an outer peripheral surface near the opening of the body, and to the inner wall surface of the syringe. And a collar member slidably formed while maintaining the close contact state.
- the brim member is formed of two annular curved portions that are in close contact with different inner surface regions along the circumferential direction of the inner wall surface of the syringe.

- the capillary channel leading to the inside of the Jodo portion in that it is composed of.
- FIG. 1 is a perspective view showing an embodiment of the present invention
- FIG. 2 is a schematic longitudinal sectional view of FIG. Fig. 3
- Fig. 3 is a partially enlarged view of Fig. 1
- Fig. 4 is a schematic vertical sectional view showing a conventional example
- Fig. 5 is a schematic vertical sectional view showing another conventional example
- Fig. 6 is another conventional example.
- FIG. 7 is a schematic longitudinal sectional view showing still another conventional example.
- the vertical movement along the inner wall surface of the syringe causes the flange member coupled to the outer peripheral surface of the cylindrical body portion to be in close contact with the inner wall surface of the syringe. The point is that it is possible to keep the
- the plunger does not tilt with respect to the syringe, so that the plunger can always slide smoothly.
- the collar member that comes into surface contact with the inner wall surface of the syringe is formed of two annular curved surface portions that are in close contact with different inner surface regions along the circumferential direction of the inner wall surface of the syringe.
- the surface contact of the collar member with the inner wall surface of the syringe can be made more stable, so that the inclination of the plunger can be prevented, and such a close contact state can be obtained. This is because the plunger can be more smoothly moved in the axial direction while maintaining the pressure.
- a narrow pipe passage is formed from the vicinity of the joint between the collar member and the cylindrical body to the inside of the cylindrical body.
- This narrow channel has a function of discharging air contained in the liquid material to the outside of the plunger, thereby preventing air from being trapped in the contact boundary surface between the collar member and the inner wall surface of the syringe. It is possible to prevent the liquid material from being discharged more stably.
- the entire plunger is formed of a relatively soft elastic resin material such as Teflon resin and has a substantially shell-like thin hollow structure. This reduces the overall weight of the plunger Therefore, it is possible to make the plunger suitable for discharging a liquid material having a small specific gravity.Also, it is possible to impart elasticity to the collar member. Spreads in a mortar shape, especially near the rear end of the cylindrical body, and expands toward the inner wall surface of the syringe, so that the collar member is more elastically and tightly adhered to the inner wall surface of the syringe and maintains the close contact state. Since the liquid material is moved while being held, it is possible to perform the discharge operation while removing the liquid material neatly.
- a relatively soft elastic resin material such as Teflon resin
- the flange member connected to the outer peripheral surface of the cylindrical body has its ⁇ -shaped curved surface in close contact with the inner wall of the syringe. To prevent it from tilting sufficiently to ensure that it is always properly inserted.
- the tapered tip will not only contain air, but also liquid material, even if it contains solids, under the appropriate clearance between the rear end and the syringe. And push it out toward the cylindrical body.
- the liquid material extruded to the upper side of the syringe regardless of the presence or absence of solid matter, has its cylindrical body fitted into the syringe in an elastically deformed state in the diameter-reducing direction, and thus each collar The member effectively blocks below it.
- the pressurized air When the pressurized air is supplied in a pulsed manner to the plunger inserted into the syringe, the pressurized air indirectly transfers the liquid material through the plunger. Liquid material is ejected accurately from the dollar attached to the tip of the syringe by a predetermined amount according to the air pressure and the pulse length.o
- FIG. 1 is a schematic perspective view of a plunger according to the present invention
- FIG. 2 is a longitudinal sectional view
- FIG. 3 is an enlarged view of a main part in FIG.
- reference numeral 10 denotes a plunger formed of a soft material having elasticity such as Teflon resin and has a shell-like thin-walled hollow structure as a whole
- reference numeral 12 denotes a conical or other shape.
- the tapered tip portion that can be formed is: 14 is a straight cylindrical shape that is continuous behind the tapered tip portion 12, a cylindrical shape whose outer diameter increases at least gradually toward the rear, and only the rear end portion has a uniform inner and outer diameter. It shows a thin-walled cylindrical body having an appropriate shape such as a cylindrical shape, and these portions are located on the same axis.
- the outer diameter of the rear end 16 of the tapered tip 1 2 is slightly smaller than the inner diameter of the syringe 18, and the air and liquid material 11 as well as the liquid material 1 are located between them. Solids that may be included in 1 are also allowed to pass and flow.
- the cylindrical body part 14 is opened at its rear end part 20 as shown by a reference numeral 22, and a brim member 24 is connected near the opening periphery.
- the collar member 24 in this embodiment is formed integrally with the cylindrical body 14, and a first annular curved surface 30 is provided at a position corresponding to the opening periphery of the cylindrical body 14.
- a second annular curved surface 32 is formed on the sliding surface against the inner wall surface of the syringe at a position distant 'from the leading end portion 12' to the tapered tip portion, and the two annular curved surfaces 30 and 3 2 are formed.
- a concave curved surface 34 connecting them is formed between them.
- Each of the annular curved surfaces 30 and 32 is formed in such a shape as to be in close contact with the inner wall surface 26 of the syringe 18, that is, the same shape as a part of the outer peripheral surface of a cylinder having an outer diameter slightly larger than the inner diameter of the syringe.
- the plunger 10 is fitted into the syringe 18 and moves in the axial direction, the plunger 10 is elastically deformed, makes close contact with the inner wall surface 26 of the syringe, and can slide while maintaining the close contact state. It is configured as follows.
- the passages 36 are provided at opposing positions so that air contained in the liquid material and a small portion of the liquid material are discharged outside through the passages.
- a column The column 38 is erected, and a screw hole is provided from the top to the bottom of the column 38 so that a male screw member (not shown) can be screwed into the column 38.
- a male screw member (not shown) can be screwed into the column 38.
- the plunger 10 When the plunger 10 is inserted into the syringe 18 filled with the liquid material 11 in advance, the plunger 10 is directed in the axial direction of the syringe 18 by hand or by using a pushing tool. By pressing the plunger, the plunger is prevented from being inclined with respect to the syringe 18 by the surface contact of the two annular curved surfaces 30 and 32 of the collar member 24 with the inner wall surface 26 of the syringe, and the plunger is smoothly inserted into the syringe. To enter.
- each part of the plunger is not only when the plunger is pushed, The same applies to the subsequent ejection process.
- the plunger 10 receives the pressure of the pressurized air.
- the vicinity of the rear end of the cylindrical body slightly spreads in a mortar shape. Therefore, the first annular curved surface 30 can be moved in the axial direction while maintaining the degree of close contact with the inner wall surface 26 of the syringe, so that the discharging operation can be performed while the liquid material is wiped clean.
- the second annular curved surface 32 is in close contact with the inner wall surface 26 of the syringe, it does not spread in the direction of the inner wall surface of the syringe. Does not.
- the first annular curved surface 30 spreads in the opposite direction to the inner wall surface of the syringe by the elastic restoring force and returns to the original contact state. Will be.
- the movement of the plunger along the inner wall surface of the syringe is performed in a state where the flange member connected to the cylindrical body and the inner wall surface of the syringe are always in close contact with each other.
- the collar member adheres more strongly to the inner wall of the syringe and the inner wall of the syringe Since the plunger is slid along the surface, the inclination of the plunger with respect to the syringe can be eliminated, and the operation of the plunger in the syringe can always be smoothly performed.
- the liquid material adhering to the inner wall surface of the syringe can be cleanly removed, it is extremely easy to visually check the liquid level from the outside of the syringe.
- the air pressure acting on the plunger is directly transmitted to the liquid material to ensure that the expected amount of liquid is discharged, and at the same time, the compressed suction air is pressurized. Liquid material dripping from the tip of the dollar can be almost completely prevented due to re-expansion after the supply of air is stopped.
- the syringe plunger of the liquid dispenser of the present invention has a flange member that elastically adheres to the inner wall of the syringe, and allows the plunger to slide in the axial direction while maintaining the elastic close state. Fine discharge of not only medium- and high-viscosity liquid materials but also low-viscosity liquid materials.Z Even at high frequency discharge, smooth operation can always be ensured. Can be used.
