The light emitting device classification apparatus 10 according to the present invention performs a process of classifying the tested light emitting devices by grades according to the test results.

1 and 2, the light emitting device sorting apparatus 10 according to the present invention includes a sorting unit 1 for classifying the tested light emitting devices (not shown) by grade. The classification unit 1 may be provided with grade information assigned to a corresponding light emitting device according to a test result of the tested light emitting device. The classification unit 1 may classify the tested light emitting devices by grades based on the provided grade information. Grade information given to the tested light emitting device may be provided from a tester (not shown) installed in the light emitting device test handler 100 (shown in FIG. 1).

Referring to FIG. 2, the sorting unit 1 includes a sorting mechanism 11 that moves to classify the tested light emitting devices according to grades, and the sorting mechanism 11 is rotated in a first axis direction (X-axis direction).

The first axis direction (X axis direction) and the second axis direction (Y axis direction) are perpendicular to each other.

Referring to FIGS. 2 and 3, the sorting mechanism 11 may include an inlet 111 (shown in FIG. 2) for carrying in the tested light emitting device and an outlet 112 for carrying out the tested light emitting device. Shown in 2). The sorting mechanism 11 may include a movement path (not shown) connected to each of the inlet 111 and the outlet 112. The tested light emitting device may enter the sorting mechanism 11 through the inlet 111, and may be carried out from the sorting mechanism 11 through the carrying out port 112 through the moving path.

2 and 3, the sorting mechanism 11 is rotatably coupled to the first coupling mechanism 12 in the first axial direction (X-axis direction). As the sorting mechanism 11 rotates in the first axial direction (X-axis direction), the discharge port 112 may rotate in the first axial direction (X-axis direction). The sorting mechanism 11 may linearly move in the second axial direction (Y-axis direction) as the first coupling mechanism 12 linearly moves in the second axial direction (Y-axis direction). As the sorting mechanism 11 linearly moves in the second axial direction (Y-axis direction), the discharge port 112 may linearly move in the second axial direction (Y-axis direction). Accordingly, the sorting mechanism 11 moves in the first axial direction (X-axis direction) and the second axial direction (Y-axis direction) to thereby move the tested light emitting device from the discharge port 112.

First, when the classification mechanism 11 classifies the tested light emitting device while linearly moving in both the first axial direction (X axis direction) and the second axial direction (Y axis direction), the classification device 11 ) Moves linearly in the first axial direction (X-axis direction), the position of the inlet 111 for the light emitting device tested to enter the sorting mechanism 11 is also in the first axial direction (X-axis direction). Will move straight. Therefore, as the sorting device 11 moves, the distance at which the tested light emitting device moves in the first axial direction (X-axis direction) to enter the inlet 111 also changes, so that the sorting device 11 is changed. According to the position of the light emitting device tested to enter the sorting mechanism 11, the distance to move in the first axis direction (X-axis direction) may increase.
