[0042] A plurality of material slots 3 are arranged on the polygonal prism 2, so that the polygonal prism 2 can accommodate a plurality of LED chip samples at one time, and the swivel 5 is set in the upper end of the support frame 6, and the cylinder 8 is driven, and the cylinder 8 drives the rack 7 to move, and the rack 7 is meshed with the gear 4, and can rub the gear 4 to rotate, and at the same time, the gear 4 drives the polygonal prism 2 to rotate; in this embodiment, the detection probe 1 is one part of the LED Raman spectrum continuous detection device, when the detection probe 1 is opposite to the LED chip sample in one of the material slots 3, the detection is started, and after the detection is completed, the cylinder 8 is driven, and the rack 7 rubs the gear 4 and drives the polygonal prism 2 to rotate. The polygonal prism 2 arranged in this embodiment is a hexagonal prism, so the rotation angle is sixty degrees, so that the adjacent LED chip samples are opposite to the detection probe 1, and the rotation direction is as follows Figure 7 As shown in the figure, the cylinder 8 drives the rack 7 to move to the left, and rubs the gear 4 to rotate in the counterclockwise direction; the entire rack 7 can intermittently rub the gear 4 to rotate five times, so that the LED chip samples in each material slot 3 on the polygonal prism 2 can be opposite to the detection probe 1;

When the distance between the detection probe 1 and the LED chip sample is too large, the detection probe 1 cannot detect the LED chip sample. If the detection probe 1 is close to the LED chip sample, when the polygonal prism 2 rotates, the polygonal prism 2 itself will touch the detection probe 1, affecting the normal detection of the LED Raman spectrum continuous detection device.

At this time, the bottom plate 9 moves down and resets, and the detection probe 1 is close to the LED chip sample. At this time, the distance between the detection probe 1 and the LED chip sample becomes the preset distance, and it is the normal working distance of the detection probe 1.

[0057] Working principle: In this embodiment, the shape of the designed material trough 3 is not limited to Figure 6 The elliptical shape shown in the figure may also be a circular shape or a rectangular shape. The material slot 3 is made according to the LED chip sample so that the LED chip sample can be stably embedded in the material slot 3.

The polygonal prism 2 arranged in this embodiment is a hexagonal prism, so the rotation angle is sixty degrees, so that the adjacent LED chip samples are opposite to the detection probe 1, and the rotation direction is as follows Figure 7 As shown in the figure, the cylinder 8 drives the rack 7 to move to the left, and rubs the gear 4 to rotate in the counterclockwise direction; the entire rack 7 can intermittently rub the gear 4 to rotate five times, so that the LED chip samples in each material slot 3 on the polygonal prism 2 can be opposite to the detection probe 1;

[0059] The LED Raman spectrum continuous detection device pre-installs the LED chip samples in the material slot 3, and the material slot 3 allows the LED chip samples to be opposite to the detection probe 1 one by one. Compared with the existing method, the steps of adjusting the position of the LED chip samples on the sample stage are reduced. At the same time, after the detection of one LED chip sample is completed, the rotation unit can be used to control the rotation of the polygonal prism 2 so that the adjacent LED chip samples are rotated to a position opposite to the detection probe 1.

[0060] In this embodiment, the distance between the detection probe 1 and the LED chip sample is taken into consideration. When the distance between the detection probe 1 and the LED chip sample is too large, the detection probe 1 cannot detect the LED chip sample. If the detection probe 1 is close to the LED chip sample, when the polygonal prism 2 rotates, the polygonal prism 2 itself will touch the detection probe 1, affecting the normal detection of the LED Raman spectrum continuous detection device. For this purpose, a support mechanism is provided, and the support mechanism cooperates with the protrusion 16 on the polygonal prism 2 to perform; when the polygonal prism 2 rotates, the protrusion 16 pushes the inclined surface 11 on the lower surface of the bottom plate 9, tilting the bottom plate 9 to push up, so that the detection probe 1 is away from the polygonal prism 2.
