The present invention relates to a nozzle of a dispenser for high precision dispensing, and more particularly, to a dispenser dispenser for dispensing a dispenser having a cleaning effect And more particularly, to a nozzle of a high precision dispenser which enables high-quality dispensing.

A dispenser for dispensing a predetermined amount of dispenser liquid through a nozzle and applying the dispenser dispenser a predetermined amount to a corresponding position of a target object in an accurate and predetermined amount, It is used for coating or joining parts.

The structure of a conventional dispenser will be described with reference to the accompanying drawings.

1 and 2, the dispenser includes a rectangular driving unit 10, a coupling unit 20 mounted on a bottom surface of the driving unit 10, A nozzle unit 30, and a syringe unit 40 mounted on a side surface of the engaging unit 20.

A tappet 11 which vibrates (moves forward and backward) to the lower end of the driving unit 10 is installed so as to protrude therefrom. The tappet 11 protrudes from the inflow hole 21, the tappet 11 is inserted and mounted.

The coupling portion 20 includes an inlet hole 21 into which the tappet 11 of the driving portion 10 is inserted and a coupling portion 21 formed on the bottom surface of the coupling portion 20 and to which the cover portion 33 of the nozzle portion 30 is fitted 22 and a mounting hole 23 on which a syringe portion 40 filled with a dispenser liquid is mounted.

In addition, the coupling portion 20 has an internal structure in which the dispenser liquid supplied through the syringe portion 40 flows into the inflow hole 21.

The nozzle unit 30 includes a guiding 31 inserted into the coupling part 22 of the coupling unit 20 through an O-ring 34, a nozzle 32 inserted and mounted on the bottom surface of the guidance unit 31, And a lid part 33 covering the guidance part 31 and the nozzle 32 and fastened to the fastening part 21 of the fastening part 20.

3, the nozzle 32 has a funnel-shaped internal structure, and includes a spray hole 32a through which the dispenser liquid is discharged, a discharge port 32b through which the dispenser liquid is exposed to the outside, And a receiving portion 32c.

The operation of the dispenser configured as described above will be described below.

First, when a predetermined power source (pulse waveform having a frequency) is applied from the power supply line 17, the piezoelectric element module installed in the driving unit 10 operates and the tappet 11 connected to the piezoelectric element module performs vibration motion.

When the syringe part 40 filled with the dispenser liquid is attached to the mounting hole 23 of the engaging part 20, the dispenser liquid flows into the inflow hole 21 of the engaging part 20, Is filled in the accommodating portion 32c of the nozzle 32 through the internal space of the guiding 31 passing through.

In this state, when the tappet 11 moves downward, the dispenser liquid accumulated in the accommodating portion 32c of the nozzle 32 is injected to the outside through the injection hole 32a.

When the tappet 11 is retracted upward, the injection is stopped. Such a vibration operation is repeated so that a certain amount of dispenser liquid is jetted at a set time interval.

When the ejection operation is continued, the dispenser liquid is gradually accumulated in the injection hole 32a of the nozzle 32 and the discharge part 32b around the nozzle 32, and the injection hole 32a is blocked later do.

This is because the dispenser liquid has a certain viscosity.

Therefore, after the dispensing operation is performed for a predetermined time, the nozzle portion must be cleaned.

Conventionally, this Applicant's Patent No. 10-1289501 discloses such a nozzle cleaning blade.

This will be described with reference to FIGS. 4 and 5. FIG.

The nozzle cleaning blade 50 is installed on one side of a work tray T which is fed right and left along a rail D.

After the dispenser performs the dispensing operation, the dispenser moves to the place where the nozzle cleaning blade 50 is installed when the set time has elapsed, and then performs the nozzle cleaning operation .

The nozzle cleaning blade 50 has a structure in which a rubber plate 52 having a plurality of blades 52a formed vertically is fixed through a bracket 51. As shown in FIG. 5, the nozzle unit 30 of the dispenser is made of rubber The dispenser liquid that contacts the surface of the nozzle unit 30, that is, the discharge unit 32b of the nozzle 32, while being in contact with the blade unit 52a and repeatedly moving left and right, is removed and cleaned.

However, in such a conventional method, it is difficult to completely remove the dispenser liquid when cleaning the discharge portion 32b of the nozzle 32 by using the nozzle cleaning blade 50.

This is because when the blade portion 52a of the nozzle cleaning blade 50 performs cleaning while sweeping the spray hole 32a of the nozzle 32 and the discharge portion 32b around the spray hole 32a, The most of the dispenser liquid was removed while the dispenser liquid attached to the dispenser was wiped off, but a small amount of the dispenser liquid occluded a part of the dispensing holes 32a.

If the outlet of the spray hole 32a of the nozzle is not completely opened and some of the nozzle is clogged, there is a problem in dispensing quality.

FIG. 6 is a sectional side view of a main part of a dispenser equipped with the nozzle of the present invention, FIGS. 7 (a) and 7 (b) are perspective views of the nozzle of the dispenser according to the present invention, and FIG. 8 is a side sectional view of the nozzle of the dispenser according to the present invention.

As shown, the nozzle of the dispenser of the present invention includes:

A driving unit 10 installed to project a tappet 11 vibrating to a lower side of the driving unit 10; a coupling unit 20 mounted on a bottom surface of the driving unit 10; And a syringe unit 40 mounted on a side surface of the coupling unit 20. The nozzle unit 30 includes an O-ring 34 disposed inside the coupling unit 22 of the coupling unit 20, A nozzle 100 inserted and mounted on the bottom surface of the guiding 31 and a guiding part 31 covering the guiding 31 and the nozzle 100, The nozzle 100 has a funnel-shaped internal structure and includes a spray hole 101 through which the dispenser liquid is discharged and a discharge port 103 through which the discharge port 103 is exposed to the outside And a receiving portion 102 in which a predetermined amount of the dispenser liquid is received,

The nozzle 100 is formed with a ring groove 104 at a predetermined interval around the injection hole 101 in the discharge portion 103 around the injection hole 101.

  Such a ring groove 104 functions to induce a perfect cleaning effect when the dispenser liquid cleaning operation is performed.

10, when the blade portion 52a of the nozzle cleaning blade 50 sweeps the discharge portion 103 of the nozzle 100 while sweeping the discharge portion 103 of the nozzle 100, When the dispenser liquid is pushed in one direction while being pushed by the blade portion 52a, the liquid drops into the ring groove 104 formed in the discharge portion 103 to reduce a load applied to the blade portion 52a, The dispenser liquid that has fallen into the nozzle part 30 is moved to the outside of the nozzle part 30 while being moved along the ring groove 104 to perform a physical operation.

Therefore, the dispenser liquid remaining in the spray hole 101 and the discharge hole 103 of the nozzle 100 is completely removed so as not to block the inlet of the spray hole 101 at all.

9, the nozzle 100 of the present invention has a funnel-shaped structure, which is an internal structure of the nozzle 100, as shown in FIG. 9, in which the tangential part between the spray hole 101 and the receiving part 102 of the triangular shape is a curved part 105). ≪ / RTI >

3, the curved surface portion 105 moves in a downward direction when the tappet 11 moves downward to perform a spraying operation. When the dispenser liquid is sprayed from the receptacle 102, .

The straightness means smooth injection operation when the dispenser liquid accumulated in the receiving portion 102 of the nozzle 100 is ejected to the outside through the injection hole 101.

That is, the conventional internal structure of the nozzle has a slight obstacle to the straightness of the injection form due to the angular shape when the dispenser liquid is sprayed in the angled contact face between the receiving portion and the injection hole. However, the present invention solves this problem through the curved surface portion 105.

Hereinafter, the driving operation of the dispenser of the present invention will be described.

First, when a predetermined power source (pulse waveform having a frequency) is applied from the power supply line 17, the piezoelectric element module installed in the driving unit 10 operates and the tappet 11 connected to the piezoelectric element module performs vibration motion.

When the syringe part 40 filled with the dispenser liquid is attached to the mounting hole 23 of the engaging part 20, the dispenser liquid flows into the inflow hole 21 of the engaging part 20, Is filled in the receiving portion 102 of the nozzle 100 through the internal space of the guiding 31 passing through the nozzle.

In this state, when the tappet 11 moves downward, the dispenser liquid accumulated in the receiving portion 102 of the nozzle 100 is ejected to the outside through the injection hole 101.

When the tappet 11 is retracted upward, the injection is stopped. Such a vibration operation is repeated so that a certain amount of dispenser liquid is jetted at a set time interval.

When the spraying operation is continued, the discharged dispenser liquid gradually accumulates in the injection hole 101 of the nozzle 100 and the discharge part 103 around the nozzle.

Accordingly, when the dispensing operation is performed for a predetermined time, and the time for cleaning the nozzle portion is reached, the dispenser stops the dispensing operation and places the nozzle 50 for cleaning on the work tray T After moving, the nozzle cleaning operation is performed.

That is, when the nozzle unit 30 of the dispenser contacts the blade unit 52a of the nozzle cleaning blade 50 to clean the nozzle, the blade unit 52a moves forward and backward while the work tray T moves back and forth, The discharge portion 103 is swept while being cleaned.

At this time, when the dispenser liquid adsorbed to the discharge portion 103 is pushed by the blade portion 52a and pushed in one direction, the liquid drops into the ring groove 104 formed in the discharge portion 103, The dispenser liquid that has fallen into the ring groove 104 is moved along the ring groove 104 while being physically moved to the outside of the nozzle unit 30 through the spray hole 101, .

Therefore, the discharge port 103 of the nozzle 100 and the spray hole 101 of the nozzle unit 30 are completely cleaned.
