Description

[0001] APPARATUS FOR SUPPLYING LED LENS [0002]

The present invention relates to a lens supply device for LED, and more particularly, to a lens supply device for an LED for receiving an LED lens from a hopper and aligning the lens to a predetermined position without being inverted, will be.

In general, a light emitting diode (LED) is a semiconductor light emitting device that emits light when a current flows, and is a PN junction diode made of GaAs or GaN optical semiconductor to convert electric energy into light energy.

1 and 2, a substrate 200 on which a circuit pattern is formed is provided, and LEDs 210 are arranged on the substrate 200 at a predetermined interval according to a circuit pattern A plurality of arrays are formed. Since the LED 210 emits light toward the front without diffusing the light, it is necessary to arrange many LEDs 210 on the substrate with a narrow interval. In this case, since the LED 210 is expensive, there is a disadvantage that the overall cost of the product is increased.

3 and 4, a diffusion lens 500 for diffusing the light emitted from the LED 210 is provided on the substrate 200, and the LED 210 is mounted on the substrate 200 at an appropriate interval, The LED 210 is mounted on the LED 210 so that light is diffused through the lens 500 even if the number of LEDs 210 is reduced. The same effect can be expected. In this case, even if the lens 500 is additionally used, since the price is generally lower than that of the expensive LED 210, the production cost can be greatly reduced.

5 and 6, a convex portion 530 (a portion for diffusing light emitted from the LED chip) is formed on the surface of the lens 500 On the back surface of the substrate 200, there are formed three adhesive protrusions 510 for mounting the lens 500 on the substrate 200 at regular intervals, and at the edge thereof, a mounting unit is provided at a position capable of picking up the lens 500 toward the substrate 200 A setting projection 520 is formed.

When the convex portion 530 of the lens 500 configured as described above is supplied to the yarn end side in a state of being positioned on the upper side, the mounting unit holds the positioning protrusion 520 formed at the edge of the lens 500, And the LED 210 may be mounted on the front surface of the LED 210 as shown in FIG. At this time, the lens 500 is attached and fixed to the LED 210 through the adhesive protrusion 510 while keeping a proper gap therebetween.

Since most of the lens 500 is manually supplied when the lens 500 is supplied to the body side, the number of working persons increases, resulting in a significant reduction in the working efficiency and a significant decrease in productivity.

On the other hand, conventionally, as disclosed in a material supply apparatus (Patent No. 10-0971119) for automatically aligning and supplying a material such as a chip from a hopper, a material is supplied from a hopper to a supply means, And the speed is controlled to be transmitted to the vibration.

Therefore, when the material fed from the hopper is the lens 500 There is a problem that the conventional material supply device can not be used. That is, the bottom surface of the lens 500, on which the adhesive protrusions 510 are formed, is flat, and the upper surface, that is, the convex portion 530 is rounded, That is, the convex portion 530 should be supplied so that the convex portion 530 is positioned at the upper portion. If the convex portion 530 is positioned at the lower portion and turned upside down, it must be turned over again.

However, according to the conventional technique, when the chip is dropped from the hopper and supplied, the posture of the chip, that is, the attitude in the planar state is supplied in a non-uniform state. Therefore, when the material supplied from the hopper is the lens 500, The position of the lens 500 at the position of the lens 500 is not constant and the adhesive protrusion 510 of the picked up lens 500 can not be accurately aligned and mounted on the mounting position of the actual organs.

The deflection movement guide member 153 is disposed in parallel with the lens discharge hole 141a as a rod. Therefore, as shown in FIG. 12F, the lens 500 is supported at one end of the deflection movement guide member 153, and the other end moves to the inclined posture by supporting one side lower end of the bottom surface of the guide rail 141a. That is, since the bottom surface of the lens 500 is flat, it is supported on one side lower deflection movement guide member 153 in an inclined state, and the other lower side is in contact with the contact point c1 on the bottom surface, And can be moved while maintaining.

On the other hand, when the lens 500 is transported in an inverted state as shown in FIG. 12G, since the convex portion is brought into contact with the bottom surface of the guide rail 141a, the contact point c2 becomes the contact point c1 toward the lens discharge hole 141c. And the case (θ3) in which the inclination of the lens 500 is inverted than the normal case (θ2) is small. Since the contact point c2 is a rounded convex portion, the posture of the lens 500 becomes unstable while being moved, and is not supported by the deflection guide member 153 but falls to the lens discharge hole 141c to be separated .

The deflection-in guide portion 155 guides the lens 500, which enters the deflection guide member 153, to be shifted to a pre-tilted position and transferred.
