Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component cleaning device for cleaning components such as processed components and circuit boards in liquid.

[0002]

[Prior art]

 Conventionally, in an apparatus that cleans a part while it is immersed in a liquid, a high cleaning efficiency cannot be obtained simply by immersing the part.Therefore, a mechanism for swinging the part back and forth or up and down and rotating it is used. It is provided to enhance the cleaning effect during immersion cleaning.

For example, in the cleaning apparatus of FIG. 10, the basket 50 in which the component P is housed is dipped in the liquid tank 51, and the holding plate 52 for holding the same is moved up and down by the crank mechanism 53, whereby 50 is rocked up and down in the liquid. Further, in the cleaning apparatus shown in FIG. 11, the basket 50 accommodating the parts P is vertically rotated (twisted) alternately in the opposite direction by the rotating and elevating / lowering device 54 while vertically moving in the liquid tank 51. .

[0004]

[Problems to be solved by the device]

 However, the conventional swinging mechanism or rotating mechanism for enhancing the cleaning effect has a drawback in that the structure and control are complicated and the apparatus becomes expensive. Further, since these mechanisms are large, the entire cleaning device becomes large.

Further, in the case where the height of the liquid surface with respect to the component is predetermined, for example, as shown in FIG. 12, the component P held on the pallet 55 has an opening a and the level of the liquid surface is If water enters here when H rises, the level H of the liquid level must be controlled accurately so that it does not reach the opening a. However, if the rocking mechanism or rotating mechanism is operated to enhance the cleaning effect, the liquid level becomes wavy, which makes it difficult to control the height of the liquid level.

An object of the present invention is to provide a parts cleaning device which has a simple structure and control, is inexpensive, can make the device small, and can easily control the liquid level.

[0007]

[Means for Solving the Problems]

 The present invention includes a liquid tank for containing a liquid for cleaning a component, a holding member for holding the component immersed in the liquid, and a vibration generator attached to the holding member.

[0008]

[Action]

 When the vibration generator is driven, the holding member vibrates, and as a result, a slight vibration is applied to the component immersed in the liquid. This slight vibration causes (1) forcible relative movement in the contact area between the component and the liquid, (2) removal of bubbles adhering to the surface of the component, (3) uneven surface or blind holes. It has the effect of permeating the liquid, and the cleaning effect is enhanced by such an operation.

【Example】

 Hereinafter, some embodiments of the present invention will be described. (Embodiment 1) In FIG. 1, a cleaning liquid is contained in a liquid tank 1, and a pair of holding bases 2 are provided outside the liquid tank 1 as holding members. These holding bases 2 are provided close to the outer wall of the liquid tank 1 so as to face each other, and are connected to a base 4 via an elastic body 3 such as rubber or a spring. Each holding base 2 extends upward from the base 4, and the upper end of the holding base 2 projects at a right angle to the liquid tank 1 side, and this serves as a pallet support 5. A component pallet (hereinafter, simply referred to as a pallet) 6 is placed on the pallet support portion 5 from above, and as shown in FIG. 2, a pin 7 provided on the pallet support portion 5 of the holding table 2 is provided. The pallet 6 is positioned on the holding table 2 by fitting the positioning hole 8 of the pallet 6 into the.

Various components such as the component P shown in FIG. 12 are held in the pallet 6 while being inserted into the component holding holes 9, and the cleaning liquid L is located near the lower surface of the pallet 6.

A vibrator 10 is provided on the side surface of the holding table 2 as a vibration generator. The vibrator 10 is well known, and as shown in FIG. 3 (A), for example, an electromagnet (solenoid) 12 provided in a main body 11 and a movable member urged in a direction away from this by a spring 13. The body 14 is included. When the electromagnet 12 is energized, the movable body 14 reciprocates in small steps to generate vibration of a predetermined frequency. The frequency can be set to, for example, about 60 Hz, and the magnitude (amplitude) of the vibration can be controlled by setting the voltage.

The body 11 of the vibrator 10 is fixed to the holding table 2 via an elastic stay 15, and the tip of the stay 15 to which the vibrator 10 is fixed is lifted from the holding table 2. The elastic body 3 interposed between the base 4 and the holding base 2 amplifies the vibration of the vibrator 10 and transmits the vibration to the holding base 2, and the vibration of the holding base 2 is transmitted to the base 4. Anti-vibration effect is suppressed. The elastic station 15 also plays a role of amplifying the vibration of the vibrator 10.

Such a vibrator 10 (and the elastic body 3) may be provided on both of the pair of holding bases 2, or may be provided on only one side. Further, although it is desirable to provide the elastic stay 15 or the elastic body 3 such as rubber, it is not essential and can be omitted. Further, as shown in FIG. 3B, a vibrator 10 of a type in which a U-shaped main body 11 is also used as a spring member and a movable body 14 fixed to the tip end thereof is reciprocally moved by an electromagnet 12 may be used. it can.

In the above-described cleaning apparatus, the component P is cleaned while being immersed in the cleaning liquid in the liquid tank 1. At that time, the vibrator 10 is driven, and its vibration causes the holding table 2 and the pallet 6 to vibrate. After that, it is transmitted to the component P, and the component P is slightly vibrated. In that state, the cleaning liquid L comes into contact with the cleaning liquid L, so that the relative movement of the parts P and the cleaning liquid at the contact portion, the removal of bubbles, the penetration of the cleaning liquid into the irregularities and blind holes, etc. are achieved. , The cleaning effect is enhanced compared to the case of simply dipping.

(Embodiment 2) A vibration generator 16 shown in FIG. 4 is of a rotary contact type, in which a motor 10 is fixed to a holding base 2 and a rotary plate 19 is concentrically fixed to a motor shaft 18 thereof. There is. Further, a plurality of (for example, two) contactors 20 that can elastically move in and out are provided on the outer circumference of the rotary plate 19, and the contactors 20 project to the rotary plate 19 by a certain amount by a spring 21 as shown in FIG. It is held in the opened state. Then, the rotation of the rotary plate 19 accompanying the driving of the motor 10 causes the contactor 20 to abut on the wall surface of the holding table 2, and by repeating this, vibration is generated. At the time of the contact, the contact 20 is pushed inward against the biasing force of the spring 21.

Third Embodiment In a vibration generator 22 shown in FIG. 6, a solenoid 23 (or a direct-acting cylinder) is fixed to a holding table 2 via a bracket 22a, and a movable portion 24 protruding from this solenoid 23 is a solenoid. It is moved back and forth with a predetermined amplitude by 23. As shown in FIG. 7, a contact 26, which is elastically held by a spring 25 so as to be able to move in and out, is provided at the tip of the movable portion 24, and the contact 26 repeatedly comes into contact with the side surface of the holding table 2 to cause vibration. generate.

Fourth Embodiment In FIG. 8, a hanging type holding arm 27 functions as a holding member. A component basket 30 for accommodating a large number of components P is hung on a hooking portion 29 formed at the lower end portion via a string member 31 (or a hook portion or the like), and this component basket 30 is attached to the liquid tank 1. It is designed to be immersed in the cleaning liquid. The vibrator 10 as shown in FIG. 1, for example, is attached to the wall surface of the holding arm 27 via an elastic stay 15. In this example, the vibration generated in the vibrator 10 is transmitted to the parts basket 30 via the holding arm 27 and the string member 31, and the large number of parts P contained therein are slightly vibrated with respect to the cleaning liquid L. Cleaning proceeds. Of course, the vibration generator 16 or 22 shown in FIG. 4 or 6 may be used instead of the vibrator 10.

(Fifth Embodiment) In FIG. 9, as compared with the case of FIG. 1, the holding base 32 is formed on a flat plate, and the portion corresponding to the side wall is replaced with a plurality of, for example, two holding poles 33. ing. That is, the upper end of each holding pole 33 is connected to the holding base 32, and the lower end thereof is supported by the base 4 via the elastic body 3 such as rubber or spring. Then, an appropriate vibration generator 34 is attached to the lower surface of the holding table 32, and the vibration generated by the vibration generator 34 is transmitted to the component P via the holding table 32 and the pallet 6, and the cleaning is performed in the vibrating state. To be done. It should be noted that such a structure using the holding poles 33 can be applied to the holding bases 32 on both sides, or it can be used only on one side and the holding base 2 as shown in FIG. 1 on the other side. You can also

The pallet 6 for parts shown in FIG. 1 or 9 is suitable for holding a plurality of relatively small parts P 1 (only one is shown in FIG. 1) for cleaning. However, depending on the part (for example, a relatively large press plate part), the part may be directly attached to a holding member such as the holding table 2 or 32 for cleaning without using a pallet. In that case, the vibration is directly transmitted from the holding member to the component.

[0020]

[Effect of device]

 According to the present invention, the component immersed in the liquid tank is slightly vibrated by the vibration generator, and the cleaning is performed under the vibrating state. Therefore, the cleaning effect is enhanced as compared with the case of simply immersing the component. In addition, since a complicated mechanism such as vertically swinging or rotating a pallet or basket for holding the parts is not required and the control is simple, the device can be configured to be simple, inexpensive and compact. . In addition, when the parts are rocked or rotated, the liquid surface of the liquid tank is wavy, but in the present invention, such large ripples are eliminated, so that the liquid surface control becomes easy.
