Description

[0001] APPARATUS FOR REMOVING PASTE FROM SQUEEGEE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a squeegee paste removing apparatus, and more particularly, to an apparatus for automatically removing a paste remaining on a blade of a squeegee using ultrasonic vibration.

In general, squeegee is a device used to apply various kinds of pastes. For example, squeegees are used to apply solder cream onto metal masks in conventional screen printing or semiconductor device manufacturing processes. In the semiconductor process, for example, when a solder paste is applied to a blank PCB using a surface semiconductor chip (SMT equipment), electronic parts are mounted, and the components are fused when they are passed through a reflow apparatus as a heat fusion unit. A squeegee is used for application.

The squeegee generally has a blade for spreading the paste over the application surface. First, the paste is put on the application surface, and the paste is uniformly applied while moving the blade on the application surface. Therefore, the paste remains on the blade after application due to its operating characteristics. Thus, the paste remaining on the blade makes it difficult to uniformly apply the paste in a subsequent step. Particularly, in the mass production process, since a repetitive application operation is performed several times, the paste remaining on the blade hardens non-uniformly over time, so that the uniformity of application necessarily becomes inevitably deteriorated unless it is removed from the blade. Since the operation must be performed continuously and repeatedly in a mass production process, it is deteriorated in productivity that a worker removes every time.

Therefore, a device for automatically removing the paste remaining on the blade of the squeegee is required.

Korean Patent Publication No. 10-2002-0092072

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and provides an apparatus for removing paste remaining on a blade of a squeegee using ultrasonic vibration.

The present invention provides a squeegee paste removing apparatus comprising: a vibrator module that vibrates when electric energy is applied; And a horn part coupled to the vibrator module on one side and to the blade of the squeegee to amplify the vibration transmitted from the vibrator module to transmit the amplified amplitude to the blade, Stacked structure.

The individual oscillator may be an O-ring type ceramic.

The vibration module may further include a booster disposed between the horn and amplifying the amplitude.

The horn has a length corresponding to the length of the blade, and the vibrator module can be coupled to the horn at a predetermined interval.

In the horn portion, the opposite side of the vibrator module may be inclined so that the width, which is a direction intersecting with the longitudinal direction of the blade, gradually decreases toward the end, so that the first inclined surface and the second inclined surface on the opposite side may be formed.

The blade may be coupled to the first inclined surface of the horn.

The horn may be formed by chamfering both side edges in the longitudinal direction of the lower portion.

In the horn portion, a groove groove having a predetermined depth may be formed around a portion where the vibrator module is coupled.

According to the present invention, there is provided an apparatus capable of automatically removing a paste remaining on a blade of a squeegee. Such an apparatus of the present invention can further efficiently remove the residual paste by amplifying it by further including a booster or a horn. Furthermore, the horn can operate stably by reducing the offset by reflected waves. Therefore, by using the squeegee paste removing apparatus of the present invention, it is possible to significantly improve the productivity.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 and 2 are perspective views showing a squeegee paste removing apparatus of the present invention. Fig. 3 is an exploded perspective view of the squeegee paste removing device of the present invention, and Figs. 4A and 4B are respectively a right side view and a left side view of Fig.

1 to 4B, a squeegee paste removing apparatus according to a preferred embodiment of the present invention includes a vibrator module 10 and a horn 20, and the blade B is coupled to the horn 20. As shown in the drawing, the vibrator module 10 may further include a booster 12.

The vibrator module 10 may include a plurality of individual vibrators 11 that convert into wave energy or kinetic energy when electric energy is applied. The individual vibrator 11 may be, for example, an O-ring type ceramic. As described above, in the preferred embodiment of the present invention, a plurality of the individual vibrators 11 have a laminated structure, so that it is possible to efficiently and constantly convert into the wave energy or kinetic energy with respect to the applied electric energy.

Preferably, the individual vibrators 11 have the same size and shape so that they can generate or control a constant vibration or amplitude.

A terminal portion 12 for applying electricity from the amplifier 30 (see Fig. 6) is interposed between the individual vibrators 11. For example, four individual vibrators 11 may be employed.

Preferably, the vibrator module 10 may further include a booster 15. When the booster 15 is further included, the booster 15 can be disposed between the laminated structure of the vibrator 11 and the horn 20 as shown in the figure.

When the vibrator module 10 does not include the booster 15, the laminated structure of the vibrator 11 described above can be directly coupled to the horn 20. At this time, the amplitude generated in the vibrator module 10 will be directly transmitted to the blade B from the horn 20.

The booster 15 has a shape that the circumference or diameter is reduced towards the horn 20, thereby amplifying the amplitude.

In Fig. 3, reference numerals 13, 14, and 16 denote members for coupling the elements of the vibrator module 10, 13 a metal bundle, 14 an engagement member, and 16 an insulation member.

5A to 5D are views showing the horn 20 employed in the squeegee paste removing apparatus of the present invention. 5A is a perspective view, FIG. 5B is a side view, FIG. 5C is a plan view, and FIG. 5D is a sectional view taken along line A-A.

Referring to Figs. 4A and 4B and Figs. 5A to 5D, the horn 20 may have a length in the transverse direction corresponding to the length of the blade B to be engaged. A plurality of vibrator modules 10 may be coupled to the horn 20 at predetermined intervals. Reference numeral 27 denotes a coupling for coupling the vibrator module 10 to the horn 20.

The ratio of the height at which the resonance occurs (vertical length in the figure) is determined for the vibrator module 10 and the horn 20. For example, the vibrator module 10 and the horn 20 may each have a height of a quarter wavelength or a half wavelength at which resonance occurs.

Preferably, as shown in the drawings, the opposite side of the vibrator module 10 in the horn 20 is inclined so that the width, which is a direction intersecting with the longitudinal direction of the blade B, gradually narrows toward the end, Amplified. As the end portion is inclined in this manner, the horn 20 has the first inclined face 21 and the second inclined face 22. The blade B is, for example, coupled to either one of these first and second beveled surfaces 21, 22. The second beveled surface 22 may have a fourth beveled surface 28 that is more inclined toward the blade B when the blade B is coupled to the first beveled surface 21 as in the example shown in the drawing . The vibration energy that has been downward in the longitudinal direction from the vibrator module 10 due to the inclination of the second inclined face 22 and the inclination of the fourth inclined face 28 is transmitted to the second inclined face 22 and the fourth inclined face 28, (B) and concentrated on the blade (B).

Preferably, the horn 20 may have a third inclined surface 23 formed by chamfering both side edges of the lower portion. The third inclined surface 23 serves to minimize the reflected wave by converting the downward vibration in the longitudinal direction from the vibrator module 10 to the transverse direction at the corresponding portion.

Also, preferably, groove portions 24 having a predetermined depth may be formed in the horn portion 20 around a portion where the vibrator module 10 is coupled. This groove groove 24 is intended to prevent or reduce the reflected wave from canceling the wavelength emitted from the oscillator module 10. These grooved grooves 24 may be two or more that are not connected to each other. Thus, the groove groove 24 is disposed around the coupling portion of the vibrator module 10, so that the reflected wave is directly transmitted to the vibrator module 10 or canceled with the wavelength from the vibrator module 10.

Reference numerals 25 and 26 are elements for coupling the blade B to the horn 20, 25 is a support plate, and 26 is a coupling member.

6 is a schematic block diagram of a squeegee paste removing apparatus of the present invention.

Referring to FIG. 6, the squeegee paste removing apparatus of the present invention may further include an amplifier 30 and a control unit 40. The amplifier 30 applies electricity to the vibrator module 10, and the controller 40 controls the amplifier 30.

The control unit 40 can set the operation of the apparatus in advance by the user through the input unit, though not shown here. For example, the control unit 40 may set the magnitude of the vibration or the amplitude and the setting of the electric time. In this case, an appropriate time can be set according to the product, and an appropriate output (amplitude or vibration) can be set according to the type of paste and the degree of contamination. In addition, it can be set to implement a suitable operation according to the size of the device and the amount of solder. As a result, maintenance and repair of the apparatus can be realized easily and economically.

Fig. 7 is a view showing a squeegee paste removing apparatus according to the present invention. Here, another example of the method of combining the blades is shown. 7, the step (21) of the horn 20 on which the blade B is engaged (the first inclined surface 21 in the drawing) is formed so that the blade B is substantially separated from the first inclined surface 21 Can be combined to be coplanar. In this case, the coupling is easy and a more rigid coupling state can be maintained.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
