Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaner that removes dust adhering to a paint film on a painted surface of an automobile when painting sheet metal.

[0002]

[Prior art]

 During the coating of automobile sheet metal, dust and other particles floating in the air adhere to the coating film due to static electricity. This dust, which deteriorates the coating quality, needs to be removed. Only this very small dust is removed from the coating with sound paper, but in reality, the area around the coating where the dust adheres is also rubbed. The rubbed periphery is obscured by compounding. In order to improve the blurring work that requires a high degree of skill, the present inventor has developed a cleaner with a polishing body attached to the tip of the microvibration rod (Japanese Patent Application No. 6-23335).

[0003]

[Problems to be solved by the device]

 In this cleaner, a small abrasive tip oscillates (vibrates), and the dust that comes in contact with it is separated from the coating film. Abrasive materials that require a delicate touch have a large discomfort with conventional sound paper, such as the pressing force on dust being adjusted according to the surface roughness. The present invention employs sound paper instead of the polishing body.

[0004]

[Means for Solving the Problems]

 The micro-vibration rod is exposed to the outside of the cylinder from the cleaner body that contains the motor, battery, etc., and the small board with the paper holder is fixed to the tip of the micro-vibration rod, and the sound paper is held by the paper holder. Install on. The sound paper, which has been shredded to the size of the small board, can be easily and interchangeably attached to the small board by the frame-shaped paper holder.

[0005]

[Action]

 The rotating body 4 having the eccentric piece 6 is rotated by the rotating shaft 5 of the motor 3. Since the sleeve 8 at the base of the micro-vibration rod 7 swings to the left and right according to the rotation of the eccentric piece 6, the micro-vibration rod 7 vibrates slightly in the linear direction (Fig. 4). The sand paper 13 attached to the small substrate 9 can be easily attached and detached via the frame-shaped paper holder 12. The pressing force of the sandpaper 13 against the coated surface is finely adjusted by the elastic plate 11 on the surface of the small substrate, and a delicate touch is made possible, so that only the coating film on the peripheral portion of the removed dust can be removed. Compared to the conventional manual work method that requires removing the coating film on the periphery, the blurring work is easier and the coating quality is better.

[0006]

【Example】

 The battery 2, the motor 3, and the rotating body 4 are sequentially arranged in the cleaner body 1. A large number of teeth are arranged in a row on the peripheral surface of the rotating body 4, and an eccentric eccentric piece 6 is attached to the center. The tip teeth of the rotary shaft 5 extending from the motor 3 are meshed with the circumferential teeth. In order to convert the rotational movement of the eccentric piece 6 into a linear movement, a frame-shaped sleeve 8 is loosely fitted in this eccentric piece 6, and a microvibration rod 7 integral with this sleeve 8 is supported by a bearing 10. In FIG. 4, when the eccentric piece 6 integrated with the rotating body 4 rotates, the frame-shaped sleeve 8 slightly vibrates in the left-right direction. This movement is transmitted to the small substrate 9 at the tip of the microvibration rod 7 extending from the cleaner body 1 (Fig. 1). An elastic plate 11 is fixed to the bottom surface of the small substrate 9, and a frame-shaped paper holder 12 is attached to the periphery of the elastic plate 11. The left and right ends of the sandpaper 13 are folded back by this paper holder 12 (Fig. 3). The roughness of the sand paper 13 is about 1600. If the tape-shaped sandpaper 13 shredded to the width of the small substrate 9 is carried on site, the replacement of the paper holder 12, which is a consumable item, becomes easy. In particular, since the roughness of the paper holder 12 to be used varies depending on the coating film and dust attached to the coating film, it is of great significance to easily replace it. Moreover, since the left and right sides of the sandpaper 13 having an appropriate hardness are folded back by the paper holder 12 and the frictional force received from the surface of the elastic plate 11 is large, even if the sandpaper 13 is rubbed against the coating film, peeling occurs. Or it does not twist.

The sand paper 13 is dipped in water or the like and then lightly pressed against the coating film (FIG. 2). The sand paper 13 integrated with the small substrate 9 that vibrates slightly in the direction of the arrow easily removes dust adhering to the coating film. Since the sandpaper 13 is lightly pressed against the coating film while the cleaner body 1 is gently rotated, the dust periphery is almost uniformly scraped off without scratch marks on the coating film. It is also due to the elastic plate 11.

After the sheet metal coating work, the surface coated on the automobile is observed obliquely from behind to find out whether or not it adheres to the coating film. Craftsmen can easily find this dust, but it is barely noticeable to an amateur. This dust is like a very fine lint floating in the air, much smaller than the dust we recognize. In order to remove this dust, the coating work in the vicinity had to be peeled off over a wide area until now. In the present invention, as described above, dust can be easily removed and the blurring area around the coating film can be minimized.

[Effect of device]

 In short, in the present invention, the microvibration rod 7 is exposed from the cleaner body 1 to the outside of the cylinder, the small substrate 9 having the frame-shaped paper holder 12 is attached to the tip of the microvibration rod 7, and the shredded sandpaper 13 is replaced. Since it is freely attached to this small substrate 9, the removal area of its peripheral portion is minimal when removing dust, and a uniform peeling surface without scratch marks is possible.
