Description

[0001] The present invention relates to a method for manufacturing a lighting apparatus,

BACKGROUND OF THE INVENTION [0002] Various embodiments relate to a method of manufacturing a lighting device, and more particularly, to a method of manufacturing a lighting device capable of preventing liquid from penetrating into the interior.

A light emitting diode (LED) is a kind of semiconductor device that can emit light of various colors by forming a light emitting source through the formation of a PN diode of a compound semiconductor. Such a light emitting device has a long lifetime, can be reduced in size and weight, and can be driven at a low voltage. In addition, these LEDs are resistant to shock and vibration, do not require preheating time and complicated driving, can be packaged after being mounted on a substrate or lead frame in various forms, so that they can be modularized for various purposes and used as a backlight unit A lighting device, and the like.

Inspection of assembly parts, etc. is periodically and continuously performed in the equipment assembly line or parts production line. Inspection work can be carried out in various ways depending on the type of parts, but in general, the inspection is mainly performed by using a vision camera or the like to check the shape, dimensions and specifications of the inspection object.

However, in the case of a specific inspection target, liquid such as water and a lubricant is excessively scattered around the inspection target, which makes it difficult to use an existing illumination device, a vision camera, and the like. For example, when the object to be inspected is maintained at a considerably high temperature and the cooling water is continuously supplied, or when the object to be inspected is accompanied by a rapid temperature rise such as a milling or a grinding operation, When water is sprayed at a high pressure or when an object to be inspected is continuously immersed in a cleaning solution in the course of manufacture and inspection, water and / or oil components scattered around the object penetrate into the illumination device, Parts can be damaged or attached to the front of the light source or to the lens and protective glass mounted on the vision camera, thereby continuously interfering with the inspection work.

In order to solve such a problem, a method of forming a waterproof structure in a conventional illumination device or a camera device has been used. However, the conventional waterproof structure is merely a passive waterproof structure which is a level of simply coating the gap between liquid permeable gaps with a resin such as epoxy or urethane, and there is a limitation in preventing the penetration of the liquid to be scattered.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the present invention is only defined by the claims.

Hereinafter, a lighting apparatus according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7. FIG. The term "illuminating device" is not limited as long as it means a device which can be used as an illumination, and includes a lighting device for inspection and the like.

Hereinafter, the inspection illumination device will be mainly described as an example, but the present invention is not limited thereto.

1 is a perspective view of a lighting apparatus according to an embodiment of the present invention.

1, a lighting apparatus 1 according to an embodiment of the present invention includes a housing 100 having an opening 101 formed at one end thereof, a light source 110 (see FIG. 2) formed inside the housing, And a compressed air injection hole 102 passing through one side of the housing 100. The opening 101 is opened toward an object to be inspected to which the illuminating device 1 is applied and the light source 110 formed inside the housing 100 irradiates the surface of the object to be inspected through the opening 101.

At this time, compressed air can be injected into the housing 100 through the compressed air injection hole 102, and the air injected into the housing 100 can be injected at a high pressure through the opening 101. That is, the opening 101 serves not only as a passage through which light irradiated to an object to be inspected passes, but also as a spray nozzle for spraying high-pressure compressed air around the object to be inspected. When the compressed air injected into the compressed air injection hole 102 and injected into the opening 101 is scattered by the water and / or the oil-containing liquid around the inspection object, It is possible to effectively prevent infiltration into the interior of the airbag. One or more compressed air discharge holes (refer to 103 in FIG. 2) are formed on the outside of the housing 100 in addition to the openings 101 so that compressed air can be injected in different directions around the housing 100, So that the liquid component that may be introduced into the housing 100 may be discharged to the outside.

Such a structure is an active waterproof structure that fundamentally prevents the liquid from penetrating into the inside of the apparatus, and is different from a passive waterproof structure that is dependent on the waterproof resin as in the prior art. With the illumination device 1 having such a structure, the inspection work can be smoothly performed even in the situation where the cooling water, the lubricant, the cleaning liquid, and the like are scattered.

The illuminating device 1 may be integrally formed with the housing 100 such that the barrel portion 200 and the camera 300 are connected to each other continuously and the camera 300 is disposed inside the barrel portion 200 An object to be inspected, which is an example of a subject, can be easily photographed through the lens and the opening 101 arranged. Therefore, not only the camera 300 need not be installed separately from the lighting device but also the inspection work can be performed easily without being affected by adhesion of the liquid scattering due to the exposure of the lens portion of the camera 300 or the like being minimized will be.

Hereinafter, the structure of the lighting apparatus 1 having such features will be described in more detail.

FIG. 2 is an exploded perspective view of the housing of the illumination device of FIG. 1, and FIG. 3 is a cross-sectional view illustrating the inside of the housing of FIG.

Referring to FIGS. 2 and 3, the housing 100 is formed in a hollow shape, and a light source 110 and other components can be accommodated therein. The housing 100 may be formed in various forms having a receiving space therein, but it is preferable that the housing 100 is formed into a cylindrical shape or a part thereof as a conical shape.

An opening 101 is formed at one end of the housing 100. The opening 101 may be formed in the shape of a circular hole passing through the housing 100 and is directed to the object to be inspected while the inspection operation is performed. Therefore, the light passing through the opening 101 can be easily irradiated toward the object to be inspected, and the compressed air passing through the opening 101 can be easily injected toward the object to be inspected.

On the other hand, the cross-sectional area of the housing 100 is minimized at one end where the opening 101 is formed. That is, by minimizing the area of the one end facing the object to be inspected and forming the opening 101 at the one end, the possibility that the scattering liquid can penetrate into the housing 100 through the opening 101 is also minimized . In order to minimize the area of one end portion, it is preferable that the housing 100 has a conical shape in which at least a part thereof gradually decreases in diameter toward the opening portion 101.

A compressed air injection hole 102 is formed on one side of the housing 100. The compressed air injection hole 102 is formed through one side of the housing 100 as shown in FIG. 3, and can have a proper size so that the compressed air can flow smoothly. The diameter of the compressed air injection hole 102 may be appropriately sized considering the width of a compressed air injection pipe (see C1 in FIG. 5 and FIG. 6) connected to the compressed air injection hole 102.

A compressed air discharge hole (103) is formed on the other side of the housing (100). A plurality of compressed air discharge holes 103 may be formed, and may be disposed around the housing 100 at a predetermined distance from each other as shown in FIG. The compressed air discharge hole 103 is formed through the housing 100 in the same manner as the compressed air injection hole 102. The compressed air discharge hole 103 is a portion through which the compressed air is injected to the outside, And to release it to the outside when it is introduced. The compressed air discharge hole 103 may be formed to have a relatively small diameter as compared with the compressed air injection hole 102.

At least one of the compressed air discharge holes 103 is located on the opposite side of the compressed air injection hole 102 as shown in FIG. 3 so that the compressed air and the liquid can be discharged together more flexibly have. Meanwhile, the compressed air discharge holes 103 may prevent the liquid, which splashes by spraying the compressed air in different directions toward the outer peripheral portion of the housing 100, from approaching the housing 100.

The openings 101, the compressed air injection holes 102, and the compressed air discharge holes 103 are all passages through which compressed air flows in or out. The openings 101, The injection pressure of air can be adjusted so as to maintain proper strength. Particularly, in the case of compressed air discharge holes 103 formed in plural numbers, not only the diameter but also the number of the compressed air discharge holes 103 can be changed, so that a part of the introduced liquid can be discharged more effectively.

Meanwhile, a connection passage 130 connected to the opening portion 101 and extending to the inside of the housing 100 is provided in the housing 100. The connection passage 130 may extend from the opening 101 toward the light source 110 and may be formed in a longitudinal shape and at least one stepped surface 131 or 132 may be formed at the light- . The diffusion panel 120 and the light source 110 are brought into contact with the stepped surfaces 131 and 132 at the end of the connection passage 130, respectively.

The connection passage 130 serves to guide the light generated from the light source 110 and the compressed air injected into the compressed air injection hole 102 to the opening 101 and the camera 100 When the subject to be inspected is photographed, it can serve as an extension of the barrel section (see 200 in Fig. 1). Therefore, the inner wall of the connection passage 130 can be painted in black to suppress irregular reflection of light.

The compressed air injection hole 102 is connected to the connection passage 130 through the housing 100 and a plurality of the compressed air discharge holes 103 may be connected to the connection passage 130. Since the light source 110 and the diffusion panel 120 are located at the ends of the connection passage 130, the inside of the connection passage 130 interconnected with the compressed air injection hole 102 and the compressed air discharge hole 103 is compressed And acts as a flow space in which air can freely flow. Accordingly, the compressed air can be circulated more smoothly to the outside of the housing 100 during the inspection work through such a configuration.

The light source 110 includes a substrate 111 that is inserted into the housing 100 and an LED 112 that is coupled to the substrate 111. The LED 112 is coupled to the substrate, and can receive light from the outside to illuminate the light. At this time, a wiring groove 160 is formed on one side of the housing 100 to accommodate a cable for supplying power, and the accommodated cable is connected to the substrate 111 via a component such as a capacitor coupled to the substrate 111. [ And can supply electric power to the light source 110 while being fixed on the periphery. One side of the substrate 111 on which the lead wires of the LED 112 and other components are arranged and its peripheral portion are coated or bonded with an ultraviolet hardening resin or the like that is easily cured in response to ultraviolet rays to penetrate liquid into the light source 110 Can be blocked in advance.

An LED (Light Emitting Diode) 112 is excellent in light efficiency compared to power consumption and has a long life span, which is easy to apply to the light source 110, but has the characteristic that the generated light goes straight. Accordingly, in order to transmit the light generated from the LED 112 to the relatively narrow opening 101 as in the embodiment of the present invention, it is necessary to appropriately change the optical path of the LED 112.

The diffusion panel 120 is interposed between the light source 110 and the opening 101 to diffuse the light emitted from the LED 112 around the opening 101. Accordingly, the light generated by the light source 110 is diffused through the diffusion panel 120 and enters the opening 101 at various angles. The light can then pass through the opening 101 and be easily irradiated to the object to be inspected. The light irradiation process will be described later in more detail.

The diffusion panel 120 and the light source 110 are in contact with the step surfaces 131 and 132 formed at the ends of the connection path 130 as described above and are easily fixed to the respective step surfaces . The light source 110 and the diffusion panel 120 may be spaced apart from each other by a predetermined distance so that the light diffusion effect can be suitably displayed. For this purpose, the step surfaces 131 and 132 may be disposed at appropriate intervals. 3, one step surface 131 may be positioned inside the other step surface 132 so that the diffusion panel 120 and the light source 110 can be positioned within the housing 100 As shown in Fig.

On the other hand, a substrate opening hole 111a and a panel opening hole 120a are formed in the substrate 111 and the diffusion panel 120, respectively. 2 and 3, both the substrate opening hole 111a and the panel opening hole 120a are overlapped with the opening portion 101 to form a kind of passageway in the housing 100. As shown in FIG.

A through hole 140 is formed in the other end opposite to the one end of the housing 100 where the opening 101 is located. The through hole 140 overlaps with the opening 101. Accordingly, a passage for passing through the opening 101, the panel opening hole 120a, the substrate opening hole 111a, and the through hole 140 is formed along the interior of the housing 100 in this order. Thus, the passage formed by the succession of the openings 101 and the open holes can be provided as a photographing passage securing the view of the camera 300 when the camera (see 300 in FIG. 1) photographs the object to be inspected.

The LED 112 can be disposed around the substrate opening hole 111a rather than the center of the substrate 111 by the formation of the substrate opening hole 111a and the light source 110 can be formed as a disc- . The diffusion panel 120 may also be formed in a disc shape having a center open corresponding to the arrangement state of the LEDs 112 and the overall shape of the light source 110. However, the shape of the light source 110 and the diffusion panel 120 may be changed to different shapes according to the position of the opening 101, the shape of the housing 100, and the like.

The structure of the light source 110 is not limited as described above. Alternatively, various light emitting sources such as a linear light emitter or a planar light emitter may be used instead of the point light emitter, such as the LED 112, You can use it as an enemy.

The other end of the housing 100, in which the through hole 140 is formed, may be formed as a removable cover 100a. Thus, the light source 110, the diffusion panel 120, and the like can be easily mounted inside the housing 100. However, this is only an example, and if necessary, the housing 100 may be integrally formed without the cover 100a.

When the cover 100a is formed, the cover 100a and the housing 100 form a bolt coupling hole 150 at a corresponding point and can be tightly coupled to each other by coupling the coupling bolt 151 thereto. In this case, the coupling bolt 151 may be formed of, for example, SUS (Steel Use Stainless Steel) or the like to prevent corrosion, and may be formed between the coupling bolt 151 and the bolt coupling hole 150 The packing 152 may be inserted to prevent the penetration of liquid, as shown in FIG. A protrusion 113 protruding in a circular direction toward each other is formed around the through hole 140 and the substrate 111 so that the cover 100a is inserted into the housing 100 in the state shown in FIG. The light source 110 can be stably fixed to the inside of the light source 100.

Meanwhile, the other end of the housing 100 having the through-hole 140 formed therein may be recessed to form the insertion groove 170 as shown in FIG. 1) is inserted into the insertion groove 170 and can be easily fixed. A part of the above-mentioned coupling bolts 151 passes through the bolt coupling hole 150 and is inserted into the barrel portion 200 So that the lens barrel 200 can be firmly fixed.

A sealing member 171 can be in close contact with the inside of the insertion groove 170. The sealing member 171 closely attached to the inside of the insertion groove 170 effectively prevents the liquid from penetrating into the gap interposed between the barrel portion 200 and the housing 100 when the barrel portion 200 is engaged. The sealing member 171 is formed, for example, in the form of a packing in close contact with both the bottom surface and the side surface of the insertion groove 170, and the portion where the through hole 140 is located can be opened. However, the shape of the sealing member 171 is not limited to this shape, and it can be deformed into various shapes such as a ring shape having a predetermined thickness or other shapes that can be closely attached to the inside of the insertion groove 170.

Although not separately described, a gap between the housing 100 and the cover 100a including the bolt coupling hole 150, the inside of the insertion groove 170, Grease) can be used to prevent penetration of fine liquids.

Hereinafter, the light irradiation process and the compressed air injection process will be described in more detail with reference to FIGS. 4 and 5. FIG.

4 is an operation diagram showing a light irradiation process of the illumination device of FIG.

Referring to FIG. 4, the light emitted from the LED 112 has a characteristic of going straight as described above. Therefore, when only the LED 112 is disposed without the diffusion panel 120, the light A generated from the LED 112 disposed around the substrate opening hole 111a can not easily reach the opening 101. [ As shown in the drawing, when the diffusion panel 120 is disposed, the light A traveling straight between the LED 112 and the diffusion panel 120 is dispersed through the diffusion panel 120, (101). Therefore, the light irradiated from the opening 101 to the object to be inspected is not a straight light, but can be in the form of diffused light spreading from the opening 101 toward the object to be inspected. Some of the light A dispersed inside the housing 100 may reach the inner wall of the connection passage 130 and be absorbed.

5 is an operation diagram showing a compressed air injection process of the illumination apparatus of FIG.

5, compressed air (B) is injected through a compressed air injection pipe (C1) connected to the compressed air injection hole (102). The compressed air injection pipe C1 is connected to an external air compressor or the like, and can receive high-pressure air.

The compressed air (B) injected into the housing 100 through the compressed air injection hole 102 is received in the connection passage 130. At this time, a part of the compressed air B can move in the direction of the barrel section 200 through the panel opening hole 120a, the substrate opening hole 111a, and the through hole 140. However, the movement is blocked by the barrel 200 inserted and fixed into the insertion groove 170, and is again received in the connection passage 130.

The compressed air B is injected at a high speed through the opening portion 101 with an increased pressure inside the connection passage 130. [ Thereby, the approach of the liquid toward the housing 100 is blocked.

At this time, a part of the compressed air (B) accommodated in the connecting passage (130) is injected into the compressed air discharge hole (103) opened to the other side than the opening (101) side. That is, the compressed air discharge hole 103 injects a relatively small amount of the compressed air B in a direction different from the opening 101, and when the liquid flows into the housing 100, To the outside of the housing 100. The compressed air discharge hole 103 is preferably formed at a position adjacent to the diffusion panel 120 and the light source 110 as shown in the drawing so that not only the inside of the connection passage 130 but also the inside of the diffusion panel 120, Even the liquid that has flowed around the light source 110 can be effectively discharged. If necessary, the compressed air discharge hole 103 may be further formed at another position.

FIG. 6 is a view schematically showing an example of use of the illumination device of FIG. 1, and FIG. 7 is an enlarged view of a part of the illumination device of FIG.

The illuminating device 1 may be formed integrally with the housing 100, the lens barrel 200, and the camera 300 sequentially connected to each other. At this time, at least one of the lenses (not shown) inside the lens barrel 200 can be overlapped with the through holes (see 140 in FIG. 5) of the other end of the housing 100. Through this structure, an image capturing passage can be formed which passes through the through hole 140 from the opening 101, passes through the inside of the barrel portion 200, and reaches the camera 300. The camera 300 can easily take an inspection object O positioned on the entire surface of the opening 101 through the lens and the opening 101 disposed inside the barrel 200. [

In addition, since the imaging passage is formed inside the illumination device 1, exposure of the lens portion such as the lens of the barrel portion 200 and the lens of the camera 300 is minimized. Therefore, the inspection work can be easily performed without adhering the liquid W scattered to the lens part or the like.

In this case, the mutual arrangement of the lens barrel 200 and the camera 300 is not limited as shown in FIG. 6, and the camera 300 may be moved in accordance with the shape change of the lens barrel 200, The point to be joined can be changed.

When the inspection operation is started, power is supplied to the light source (see 110 in Fig. 2) via the cable C2, and the camera 300 is also supplied with electric power. The cable C2 may be inserted into the extension 210 provided at one side of the barrel 200 and connected to the camera 300. [ On the other hand, compressed air (B) is injected from the compressed air injection pipe (C1) connected to the compressed air injection hole (102).

The illuminating device 1 may be fixed to a support device such as, for example, a robot arm and fixed around the inspection object O. If necessary, the illumination device 1 may be detached therefrom and manually change the inspection position from time to time. The fixing method of the lighting apparatus 1 can be formed by various methods as far as possible.

When power and compressed air (B) are supplied, light (A) is irradiated around the inspection object (O) through the opening (101). The irradiated light A becomes a form of diffused light spreading around the inspection object O as described above, and can illuminate the inspection target O and its surroundings. The camera 300 photographs the inspection object O with the appearance of the outline in this way through the opening 101 as well.

At this time, various kinds of liquid W such as a cleaning liquid, a lubricating liquid, and a cooling water may be supplied to the inspection object O. Such liquid W may be mostly composed of a component including water and / or oil.

The compressed air B injected to the inspection object O through the opening 101 is discharged from the vicinity of the inspection object O, particularly from the inspection object O to the illuminator 1, To prevent it. The illuminating device 1 can be fixed at a distance or a close distance from the inspection target O in accordance with the type of the inspection object O and the compressed air B is irradiated directly onto the inspection target O, ) Is adjacent to the inspection object (O), it is possible to effectively prevent the liquid (W) from penetrating into the apparatus.

The compressed air B is also blown around the housing 100 through the compressed air discharge hole (see 103 in FIGS. 2 and 3) as well as the opening 101 as shown in FIG. At this time, a part of the liquid W that has flowed into the housing 100 is mixed with the compressed air B and is discharged together with the cleaned air, so that the inside of the housing 100 is kept clean and the lighting apparatus 1 is smoothly operated . The compressed air B blown around the housing 100 can block the access of the liquid W toward the side surface as well as the front surface of the lighting apparatus 1 having the opening 101 formed therein. As described above, since the inflow of the liquid into the illumination device is prevented, it is possible to prevent the liquid from approaching the lens, the camera lens, etc. of the lens barrel connected thereto. As a result, the phenomenon that the surface of the lens is clouded by the liquid can be prevented, and the inspection function can be normally performed. Therefore, the inspection object O can be easily inspected by using the illuminating device 1. [

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

In the claims hereof, the elements depicted as means for performing a particular function encompass any way of performing a particular function, such elements being intended to encompass a combination of circuit elements that perform a particular function, Or any form of software, including firmware, microcode, etc., in combination with circuitry suitable for carrying out the software for the processor.
