A moving member 500 connected to the tube 250 extending from 400 and moving to an upper portion of a target bin according to the grade of the LED module, and a position moving mechanism 200 for moving the moving member 500. And an empty storage chamber 300 disposed below the position movement mechanism 200.

First, the blower 400 is supplied with a high-pressure air through the tube 250 so that the high-pressure air can be discharged to the bin 320 of the bin storage chamber 300 corresponding to the grade is supplied to the LED module is rated ( To 320).

The moving member 500 is moved by the position movement mechanism 200 while being connected to the tube 250 so that the tip opening of the tube 250 is accurately positioned in the target bin.

On the other hand, as shown in Figures 2 and 3, the position movement mechanism 200 moves the moving member 500 to move toward the opening position of the target bin. When the grade determined for the corresponding LED module is input to the controller (not shown), the controller recognizes the position of the bin corresponding to the grade and transmits the position (X-Y-axis) signal to the position moving mechanism 200. By passing it on.

The position movement mechanism 200 may linearly move the moving member 500 with respect to the turn table 210, the first driving unit 230 for rotating the turn table 210, and the turn table 210. The second driving unit 220 is configured to be included.

The first driving unit 230 determines the position according to the rotation angle θ with respect to the moving member 500 by rotating the turn table 210. The first driving unit 230 is installed on the support 232 and the first driving member 237. A first driving motor 231 having a), a first driven member 233 formed at a rotation center of the turn table 210 and rotatably coupled to the support part 232, and the first driving member 237 and the second driven member 233 is connected to the first power transmission means 234. The first driving member 237, the first driven member 233, and the first power transmission means 234 may be connected by various power transmission methods such as pulley-belt or chain-sprocket power transmission or power transmission of a gear structure. As shown in FIG. 4, a method of directly coupling the first driving motor 231 to the turn table 210 may be adopted.

The turn table 210 is supplied with the LED module for the entire bin 320 while reciprocating the 180 ° ~ 360 °. The turn table 210 may be rotated reciprocally by more than ± 360 °, in this case it is necessary to pay attention to the phenomenon that the tube 250 is twisted.

On the other hand, the second driving unit 220 is disposed below the turn table 210 as a component to move the moving member 500 relatively linear to the turn table 210, the turn table 210 Second power transmission means for connecting the second driving member 222 and the second driven member 221, the second driving member 222 and the second driven member 221 which are spaced apart from each other on the lower surface of the ( 223 and a second driving motor 225 installed on the turn table 210 and connected to the second driving member 222.

At this time, a moving member 500 is installed at one point of the second power transmission means 223 such that the moving member 500 linearly reciprocates on the turntable 210 according to the reciprocating movement of the pulley 223. .

The turn table 210 is preferably formed as a circular plate having a predetermined thickness, but is not necessarily limited thereto, and may be formed as a quadrangle or a polygon having various footnotes.

And, as shown in Figure 7, the turn table 210 is connected to the moving member 500 is a long hole guide hole 211 for preventing the movement of the tube 250 to linear movement is limited It is preferably formed.

As illustrated in FIG. 8, the second driving member 222 and the second driven member 221 of the second driving unit 220 are configured to wind or unwind the second power transmission means 223. The moving member 500 may be reciprocated in a straight line.

In addition, the power transmission method of the second driving unit 220 may be configured as a chain-sprocket.

As described above, the tube 250 is interposed between the blower 400 and the moving member 500, and is formed of a flexible resin material so that the tube 250 can be easily bent along the moving direction of the moving member 500. It is preferable.

In the case of the tube 250 made of a flexible resin material, the discharge of the LED module can be made very smoothly because static electricity does not occur in the process of passing the LED module through the inner diameter due to the characteristics of the resin material.

In addition, the tube 250 is made of a single structure that connects between the blower 400 and the moving member 500, it can significantly reduce the number of tubes compared to the prior art.

Figure 10 shows an example of the rough operation of the classification device of the LED module according to an embodiment of the present invention.

As shown in the figure, first, when the grade of the LED module is determined, information about the grade is input to the controller, and a target bin is determined. Then, the coordinates of the determined bin are calculated to operate the position movement mechanism 200. When the moving member 500 is moved by the position moving mechanism 200 and positioned above the opening of the target bin, the blower 400 operates to supply the LED module to the bin.

On the other hand, Figure 4 shows another embodiment of the first driving unit 230 applied to the present invention, the first driving motor 231 is installed in a structure that is directly coupled to the rotation center of the turn table 210.

The fixed structure of the end of the rotating shaft, for example, as shown in Figure 4, to form a gear 231a on one end of the rotating shaft of the first drive motor 231, and is recessed to engage with the gear 231a on the turn table 210 It can be configured to form a gear groove (210a) of the structure. However, other general fixing structures may be adopted.

According to such a configuration, the first driving unit 230 may omit a separate first power transmission means 234 for rotating the turn table 210.

Since the rest of the configuration is the same as the embodiment of FIG. 3, detailed description thereof will be omitted.

Furthermore, the center of rotation of the turn table 210 is fixed to the second drive motor 233 so that the second drive motor 233 and the turn table 210 rotate together by the first drive motor 231. Done.

Two second driving members 222a and 222b are disposed in parallel on the rotation shaft of the second driving motor 233, and the second driving members corresponding to the second driving members 222a and 222b are disposed in parallel. 221a and 221b are disposed, and second power transmission means 223a and 223b are connected between each of the second driving members 222a and 222b and the second driven members 221a and 221b.

Accordingly, it is possible to receive the LED module from the two or more blowers 400 to perform the classification.

In this case, since the two or more second power transmission stages 223a and 223b are rotated at the same time when the second driving motor 233 is driven, two or more blowers 400 do not simultaneously classify the LED modules at the same time. Should be classified as:

Meanwhile, as shown in FIGS. 2 and 3, the empty storage chamber 300 is a component that finally collects LED modules supplied from the blower 400 for each grade, and a plurality of bins having openings formed on upper surfaces thereof. The through hole 311 is formed to correspond to the 320.

Of course, the surface of the empty storage chamber 300 in which the plurality of through holes 311 are formed may have a serial number that can be selectively supplied according to the grade of each LED module.

On the other hand, as shown in Figure 9, when the second power transmission means 223 of the second driving unit 220 is connected in an endless track using a belt so that the sorting operation of the LED module can be made more quickly, The moving member 500 may be disposed at the center of one side and the other side of the belt in the longitudinal direction, respectively, to connect two tubes 250.

In this case, when any one of the moving member 500 is moved toward the one side from the center position at the same time the other moving member 500 is moved toward the other side.

As illustrated in FIG. 6, two or more position movement mechanisms 200 and empty storage chambers 300 may be provided.

Furthermore, the position shifting mechanism 200 and the empty storage chamber 300 may be added in a corresponding number corresponding to the number of the blowers 400.
