JPH07204563A - Cleaner for removing dust stuck at coated film of coated surface - Google Patents

Abstract

PURPOSE:To easily remove only dust stuck to a coated film, simplify a post treatment and remarkably improve a finished quality by providing a battery and a motor in a cylinder main body to convert a rotary motion of the motor to a straight micro vibration and mounting a abrasive body at a tip of a micro-vibrating rod. CONSTITUTION:The secondary battery 2 and the motor are provided in the cylinder main body 1, and a gear of a rotary shaft 5 of the motor is engaged with a peripheral gear tooth of a rotary body 4. An eccentric leaf integrated with the rotary body 4 is recessed in a base part of the micro-vibrating rod 7 and makes the base part micro-vibrate by rotation. Since the micro-vibrating rod 7 is controlled rolling by a bearing 10, this micro-vibrating rod 7 is vibrated as much as an eccentric amount of the eccentric leaf. The abrasive body 9 is mounted at a tip of the micro-vibrating rod 7 and mounted freely slidably at the tip part of the cylinder main body 1, and the tip of the micro-vibrating rod 7 is mounted at a different place to this support, and the abrasive body 9 is executed an amplitude motion using the support as a sliding center. Since the tip of the abrasive body 9 has a curvature, the abrasive body removes theoretically only dust, but a coated film at a vicinity of this dust is easy to rub practically by the micro-vibration.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaner for removing dust adhering to a coating film on a coating surface of an automobile when the sheet metal is coated. Only the dust is removed without rubbing the surrounding coating film with dust.

[0002]

2. Description of the Related Art Since dust floating in the air adheres to a coating film when coating a sheet metal of an automobile, the dust is scraped off with sandpaper after drying. Even with the utmost care, the coating film around the dust is scraped off, so the peripheral area is blurred by compounding.

[0003]

Since a series of dust removing operations affect the finish quality of sheet metal coating, a high degree of skill and attention are required. This is today's problem due to lack of skilled workers.
The present invention was devised in response to a need for an apparatus that removes only dust from a coating.

[0004]

[Means for Solving the Problems] A conversion means for converting the rotational movement of a motor in a cylinder body into a linear movement, a micro-vibration rod extending from the conversion means, and a polishing body swingably attached to the tip of the cylinder body. Then, attach the tip of the microvibration rod to a position different from the swing fulcrum. The output shaft of this motor is connected to a rotating body with an eccentric piece, the base of the microvibration rod is fitted into this eccentric piece, and a polishing body is attached to the tip of this microvibration rod.

[0005]

Operation: The toothed rotating body having the eccentric piece is rotated by the rotating shaft of the motor. The base of the micro-vibration rod whose lateral vibration is restricted by the bearing vibrates slightly as the eccentric piece rotates. As shown in FIG. 2, the polishing body at the tip of the microvibration rod is lightly contacted with dust. Dust adhering to the coating film is peeled off by the slightly vibrating polishing body. The vibration range of the micro-vibration rod depends on the amount of eccentricity of the eccentric piece, and its value is very small. Since the polishing body in contact with the painted surface has a curved surface and the vibration width is very small, the painted surface to be rubbed is also small. The range is about 2 mm centering on dust. After removing the dust, use a compound to finish the rubbed surface.

[0006]

EXAMPLE A secondary battery 2 and a motor 3 are arranged in a cylinder body 1, and gears of a rotary shaft 5 of the motor 3 are meshed with peripheral teeth of a rotating body 4. The eccentric piece 6 integrated with the rotating body 4 is fitted into the base portion 8 of the microvibration rod 7 and vibrates the base portion 8 by rotation. The lateral vibration of the micro-vibration rod 7 is restricted by the bearing 10. Therefore, the minute vibration rod 7 vibrates by the amount of eccentricity of the eccentric piece 6. The polishing body 9 may be directly attached to the tip of the micro-vibration rod 7 so that it can be exchanged. However, in FIG. It is installed in a different place from 11. As shown in the figure, the polishing body 9 swings around the fulcrum 11 as a swing center. Since the tip of the polishing body 9 has a curvature, only the dust can be theoretically removed as far as FIG. 2 is seen, but in reality, the coating film in the vicinity thereof is easily rubbed by the slight vibration of the polishing body 9. The fulcrum of the polishing body 9 of the present invention
Since there is almost no displacement (vibration) in the vicinity of 11, the shake reaction force received from the coating film when the abrasive body 9 is pressed against the coating film is extremely small.

The polishing body 9 may have a flat tip or an acute angle. It is appropriately selected according to the shape and size of the dust (or dust in some cases) to be removed. In FIG. 2, the polishing body 9 is arranged so as to be exchangeable, and a bottomed hole is formed at the tip of the microvibration rod 7, and the engaging projection of the microvibration rod 7 is fitted therein. A chuck method may also be used. Although an eccentric piece or the like is adopted as the conversion means, any means can be used as long as it is a means for converting the rotational force into a linear motion.

[0008]

In summary, according to the present invention, the conversion means for converting the rotational motion of the motor in the cylinder body into the linear motion, the micro-vibration rod 7 extending from this conversion means, and the swingable attachment to the tip of the cylinder body. Since the tip of the micro-vibration rod is attached to the polishing body 9 at a position different from the swing fulcrum, only the dust attached to the coating film by the micro-vibration of the polishing body 9 can be easily removed. Since the coating film is not rubbed more than necessary, the post-treatment is simple and the finished quality is significantly improved compared to the conventional method.
After the sheet metal painting work, the dust is found by observing the painted surface of the car from diagonally behind. Craftsmen can easily find this dust, but it is difficult for an amateur to notice. This dust is like a very fine lint floating in the air, much smaller than the normal dust we recognize. According to the present invention, the dust is removed, and the fine vibration of the polishing body 9 is slightly touched and transmitted to the coating film to remove only the dust attached to the coating film. When the tip of the polishing body 9 comes into contact with the coating film, the polishing body 9 itself shifts due to the reaction force received from the coating film, and the coating film is rubbed and peeled off more than necessary. In the present invention, since the polishing body 9 slightly oscillates, this deviation is eliminated.
