Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air gun, and more particularly to an air gun for removing dust that is electrostatically attached during a manufacturing process that requires a clean room as a manufacturing environment such as an optical disk.

[0002]

[Prior Art]

 For products such as optical discs and LCD displays that require ultra-clean manufacturing processes, if minute dust or the like adheres to the substrate due to static electricity, blow ionized compressed air to remove static electricity. It is necessary to remove the dust and blow it away by the air flow. Such dust is usually on the order of a few microns to a few tens of microns, and it is very difficult to find the place where this dust adheres. Usually, in order to find this adhesion point, the product is irradiated with light from a high-intensity lamp (such as a halogen or xenon lamp), and the operator can visually observe the transmitted or reflected light to identify the location. By using an air gun at that location, ionized air was blown until the dust was removed, and the dust that caused the defect was removed.

[0003]

[Problems to be solved by the device]

 However, in such a removal method, the appearance of dust is slightly different depending on the positional relationship between the high-intensity lamp, the illuminated object (product), and the eyes of the operator, and thus the skill of the operator is required. In addition, there are safety and health problems, such as the eyesight of the worker is reduced due to the light from the high-intensity lamp entering the eyes of the worker. Therefore, an object of the present invention is to provide an air gun capable of performing stable dust removal work easily and safely regardless of the skill level of an operator.

[0004]

[Means for Solving the Problems]

 Therefore, in order to achieve the above-mentioned object, the present invention provides an illumination section around an air gun body having an air nozzle in the center, the illumination section is a fiber, and a light source is connected to it. Furthermore, it is arranged so that the light from the illumination unit is condensed on the extension line of the air nozzle.

[0005]

[Action]

 According to this invention, the illuminating unit irradiates the object (product) with a light flux and makes it easier to find minute dust adhering to the object. The size of dust is from a few microns to a few tens of micron, but the surface of the object is usually a mirror surface or groove surfaces arranged at equal intervals, and the illumination part has sufficient brightness and the air nozzle If the light is collected at an appropriate position on the extension line, the light is scattered by the dust on the target object, so that the location of the dust can be specified. In that state, ionized air can be easily blown against the dust by ejecting compressed air, and it can be confirmed by blowing air whether or not the dust is removed by the illumination of the illumination unit.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. In the figure, reference numeral 1 is an air gun body, and a grip 2 is integrated at one end thereof. An air injection button 7 and an illumination button 8 are provided on this grip. An air nozzle 6 is provided at the center of the air gun body 1, and an illumination unit 3 is provided at the periphery. The illuminating section 3 is composed of an optical fiber 3a and has a light source 9 connected to one end thereof. Control of the air nozzle 6 and the illumination unit 3 is performed by the buttons 7 and 8 of the grip 2, and the control line 5 is wired. Incidentally, 4 is an air hose for supplying ionized air.

Next, the operation will be described. The air that has entered the ionizer 9 and the illumination lamp house (light source) 9 from the factory air supply source is ionized here, and is supplied to the air gun body 1 through the air hose 4 and passes through the air filter 13. After dust and the like are removed by, the air is ejected from the air nozzle 6. Light from a high-intensity lamp (halogen lamp or the like) installed inside the ionizer and the illumination lamp house 9 passes through the optical fiber bundle 3a and is emitted from the illumination unit 3 to the front of the air gun. The air flow 11 and the illumination light 12 are controlled by an air injection button 7 and an illumination button 8 attached to the grip 2. The signals from these button switches are transmitted to the ionizer and the lamp house 9 for illumination by the control line 5, and the air flow and the illumination light are turned on and off by the internal solenoid valve and electric switch. Be done. As shown in FIG. 2, the ends of the optical fibers 3a must be arranged so that the lights from the individual optical fibers 3a overlap in the middle of the air flow 11 and the illumination light condensing unit 10 can be formed. It is desirable that the illumination light condensing unit 10 has a size of about 10 cm in view of the workability and the flow velocity of the air flow 11.

[0008]

[Effect of the device]

 As described above, according to the present invention, it is possible to easily carry out dust adhered to the substrate of the optical disk, etc., regardless of the proficiency of the operator, with a simple structure in which the illumination section is provided around the air nozzle of the air gun body. Moreover, there is an effect that the worker can safely perform the dust removal work without reducing the eyesight.
