[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for cleaning a compact disc (hereinafter referred to as a CD), and more specifically, it is an ultrasonic device for a CD that does not need to be separately dried after cleaning by using ultrasonic waves. Cleaning device

[0002]

[Prior Art]

 Ultrasonic cleaning devices are often used to clean the surfaces of metals, glass, synthetic resin, etc. This is because when the object mass (weight) that causes dirt attached to the surfaces of these members resonates, the object mass can be released from the object surface, and this resonance action can be performed by ultrasonic waves. This is because it can be done. That is, when powerful ultrasonic waves are emitted into the water, more than 50,000 cavitations per second, or in other words, vacuum bubbles are generated, and when these bubbles burst, they generate more energy than the explosion of a mine in the sea. This is because it repels dust that causes dirt and makes it clean. In addition, ultrasonic waves have the function of accelerating water molecules, and this function causes dusts to be quickly released from objects.

By this function, when ultrasonic waves are transmitted to the cleaning liquid in which the CD is immersed, for example, when cleaning the CD, dusts attached to the CD surface are surely released, and the CD surface becomes clean.

[0004]

[Problems to be solved by the device]

 However, even if the CD surface is cleaned by immersing it in a cleaning liquid and ultrasonically cleaning it, it needs to be dried because the CD surface is wet with the cleaning liquid. For this drying, there is a method of first rinsing the washing liquid with water, and then putting it in a drying container that supplies hot air or cold air, hand-held air from a dryer, or wiping with a special cloth. However, I had to get my hands wet in any case, and it took time to dry it, which was troublesome. Further, if a hand-held dryer is used or a cloth is wiped with a cloth, dusts may adhere again during drying.

The present invention has been made in view of such a background, and an object thereof is to automatically perform washing to drying in a short time without soiling a hand, and dust may be attached at the time of drying. An object of the present invention is to provide an ultrasonic cleaning device for a CD that does not have a CD.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned object, the first means is to transfer a ultrasonic wave to the cleaning liquid in the cleaning liquid storage tank and a lower body that has a cleaning liquid storage tank in the upper part for storing the cleaning liquid at the time of cleaning, and dip it in the cleaning liquid by the ultrasonic wave. The ultrasonic wave generating means for cleaning the cleaned CD, the holding shaft protruding into the cleaning liquid storage tank for holding the CD in the cleaning liquid storage tank, the holding shaft rotation driving means for rotating the holding shaft, and the holding shaft for cleaning. The held CD is dipped in the cleaning liquid, and the upper body that closes the cleaning liquid storage tank of the lower body equipped with the CD elevating means for retracting the CD from the cleaning liquid when it is not cleaned is ultrasonically exposed to the surface of the CD. An ultrasonic cleaning device for CD that removes the attached dust was constructed.

The second means includes a lifting shaft rotation driving means, a motor that integrally lifts and lowers the holding shaft, and a driving force transmission mechanism that transmits the rotational force of the motor. Configured.

[0008] Furthermore, the third means is, in the first means, a cleaning position where the cleaning liquid is immersed in the CD cleaning liquid, and a drying position which is located above the cleaning liquid surface and is retracted from the cleaning liquid and rotated by the holding shaft drive means. Elevating means for taking three drying positions, a braking position that further rises from the drying position to brake the rotation of the holding shaft, and a damping position that further rises from the drying position to brake the rotation of the holding shaft. Set the stop position of the CD.

[0009]

[Action]

 In the above first means, the CD is held by the holding shaft, and when the power is turned on, the holding shaft drive means is driven to lower the holding shaft and immerse the CD in the cleaning liquid. When the lowering of the holding shaft is stopped and the CD is completely immersed in the cleaning liquid, the ultrasonic wave generating means is driven and ultrasonic waves are generated in the cleaning liquid by the ultrasonic wave generating means to clean the CD. When a preset time has elapsed, the generation of ultrasonic waves by the ultrasonic wave generation means is stopped automatically or manually. Next, the holding shaft is raised by the holding shaft driving means to stop the CD at a position apart from the cleaning liquid above the cleaning liquid surface. When the CD stops at a position away from the cleaning liquid, the holding shaft rotation drive means rotates the holding shaft at a high speed. As a result, the CD rotates at high speed, and the cleaning liquid on the surface of the CD is blown off by the centrifugal force. After a lapse of a predetermined time, the cleaning liquid for the CD surface is surely blown off and the CD surface is dried. When the drying is complete, stop the motor and remove the CD.

In the above-mentioned second means, the elevating means integrally raises and lowers the holding shaft drive means and the holding shaft by the motor via the driving force transmitting means such as a gear.

In the above-mentioned second means, the elevating means has three positions: a cleaning position in which the CD is immersed in the cleaning liquid, a drying position retracted upward from the cleaning liquid surface, and a braking position further elevated from the drying position. And each of them can surely perform the operation.

[0012]

【Example】

 A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial cross-sectional perspective view of an ultrasonic cleaning apparatus for CD according to an embodiment. The ultrasonic cleaning apparatus 1 for CD is composed of a lower body 2 and an upper body 3, and a tray-shaped cleaning liquid storage tank 5 for storing a cleaning liquid 6 for cleaning the CD 4 is provided above the lower body 2. .. An ultrasonic oscillator 8 as an ultrasonic wave generating means is attached to the back side of the bottom surface 7 at the center of the cleaning liquid storage tank 5, and ultrasonic waves are transmitted to the cleaning liquid 6 in the cleaning liquid storage tank 5 via the bottom surface 7. It is supposed to do. The upper body 3 is configured so that the cleaning liquid storage tank 5 can be hermetically sealed so that the cleaning liquid 6 does not leak from the cleaning liquid storage tank 5 when the lower body 2 is covered by the upper body 3. Further, the lower portion of the cleaning liquid storage tank 5 of the lower body 2 is a space.

At the center of the bottom surface 9 of the upper body 3, a drying motor 11 is provided so that the holding shaft 10 is perpendicular to the bottom surface 9. The drying motor 11 is supported by a supporting member 12 so as to be vertically movable, and a gear 14 is cut on the side surface of a motor cover 13 of the drying motor 11. A chuck 15 for holding a CD is provided at the lower end of the holding shaft 10, that is, the end on the side of the cleaning liquid storage tank 5, and a brake disc 16 is axially attached to the upper end. A drive gear 19 rotatably attached to the tip of a rotary shaft 18 of a lifting motor 17 meshes with the gear 14, and the driving force of the lifting motor 17 is transmitted to the motor cover 13 of the drying motor 11 for drying. The motor 11 can be moved up and down.

A position confirming lever 20 is provided on the motor cover 13 so as to project from the cleaning position and the drying position by switch type position sensors 22 and 23 provided on the bottom surface 9 side and the upper surface 21 side of the upper body 3, respectively. Is detected and predetermined control can be performed. Further, a brake pad 24 and a switch-type stop confirmation sensor 25 are provided on the upper surface 21.

When using the CD ultrasonic cleaning apparatus 1 configured as described above, first, the upper body 3 is removed and the CD 4 is fixed to the chuck 15. Next, it is confirmed whether or not the cleaning liquid 6 in the cleaning liquid storage tank 5 is contained in a specified amount, and if not, it is added up to the specified amount, and if it is contained, a switch (not shown) is operated to turn on the power. As a result, a control circuit (not shown) starts to operate, the raising / lowering motor 17 is energized, and the drying motor 11 is driven through the drive gear 19 and the gear 14 to the cleaning position where the CD 4 is surely immersed in the cleaning liquid 6. To lower. The stop position is the cleaning position detected by the position sensor 22 of the position confirmation lever 20. The initial position of the drying motor 11 is the uppermost stop position where the brake disc 16 contacts the brake pad 24. The control circuit stops the energization of the lifting motor 17 according to the detection output of the position sensor 22, and stops the CD 4 at the cleaning position.

When the CD 4 stops at the cleaning position as described above, the ultrasonic vibrator 8 is energized to generate ultrasonic vibrations, which are transmitted from the bottom surface 7 of the cleaning liquid storage tank 5 into the cleaning liquid 6. Then, when the above-mentioned cleaning is performed by ultrasonic waves for a preset time, the power supply to the ultrasonic transducer 8 is stopped and the cleaning is completed. This cleaning time is set by the timer in the control circuit.

When the cleaning is completed, the control circuit energizes the lifting motor 17 and similarly raises the drying motor 11 via the drive gears 19 and 14. Then, when the upper position sensor 23 detects the position of the position confirmation lever 20, the control circuit stops energizing the lifting motor 17 according to the detection output, and stops the CD4 at the drying position on the cleaning liquid surface. ..

Then, the energization of the drying motor 11 is started, and the CD 4 is rotated at a high speed via the holding shaft 10. By this high speed rotation, the cleaning liquid adhering to the surface of the CD 4 is blown off and the drying operation is performed. When sufficient time for drying set by the timer has elapsed, the energization of the drying motor 11 is stopped, and at the same time, the energization of the lifting motor 17 is started. As a result, the drying motor 11 further rises from the drying position. When the brake disc 16 contacts the brake pad 24, the stop confirmation switch 25 is turned on via the brake pad 24, and the control circuit determines that the drying motor 11 has risen to the stop position and the lifting motor 17 To stop the power supply to. At the same time, the brake disc 16 which has been rotated by inertial force is braked by the brake pad 24, and the rotations of the brake disc 16 and the drying motor 11 are stopped.

When the drying motor 11 is stopped, the upper body 3 is removed from the lower body 2, the lid is opened, and the chuck 15 is released to take out the CD 4. As a result, the CD4 drying operation can be executed easily and in a short time without getting the hands wet or dirty. Since all the washing and drying are performed in a closed container, there is no possibility that dusts adhere to the CD4 during this operation.

[0021]

[Effect of the device]

 As is clear from the above description, according to the idea of claim 1 configured as described above, the CD is immersed in the cleaning liquid, the ultrasonic cleaning is performed, and then the cleaning liquid level is automatically generated. The cleaning liquid attached to the CD is blown away by raising it to the upper drying position and rotating the CD at a high speed, so you can automatically clean and dry the CD in a short time from setting the CD to removing it from your hands. In addition to being able to perform it, all the work is done in a closed container, so there is no risk of dust adhering during the drying process.

Further, according to the invention of claim 2 which raises and lowers the CD by obtaining the driving force from the motor, the raising and lowering operation can be performed by a simple mechanism, so that the control is simple and the cost can be kept low. it can.

Further, according to the invention of claim 3, which is set so as to have the three positions of the cleaning position, the drying position and the braking position, not only the cleaning and the drying but also the braking can be surely performed. Can be shortened.
