[0001] The utility model relates to the technical field of diamond semiconductors, in particular to a selection device used for diamond semiconductor production. Background Art

[0002] With the continuous development of the semiconductor industry, more and more semiconductor materials are used in electronic devices. Ordinary semiconductor materials are constrained by their performance and their application under high temperature conditions is limited. Diamond semiconductor devices have excellent electrical properties such as high carrier mobility, high thermal conductivity and low dielectric constant, and can operate in very harsh environments such as high frequency, high power, high temperature and high pressure.

[0003] In the actual production process, the voltage values ​​of the produced diamond semiconductors are different due to differences in the skills of the production workers or the performance of the diamond itself. Therefore, in order to more accurately distinguish the levels of the produced diamond semiconductors, it is necessary to make corresponding selections through a selection machine. However, the current selection machine cannot mark the diamond semiconductor when it detects that the voltage value of the diamond semiconductor is not within the set range, which easily leads to the mixing of diamond semiconductors with different voltage values ​​in the subsequent intervals. Therefore, it is necessary to design a selection device for diamond semiconductor production to solve the above problem.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0035] The detection body 11 is fixedly mounted on the top of the long board 8. It should be noted that the voltage value of the diamond semiconductor body 5 is detected by the detection body 11;

[0036] By using the above-mentioned selection components, the diamond semiconductor body 5 is placed in the matching groove 4, and the driving motor 6 is started, so that the connecting rod 9 and the voltage detection head 10 can rotate synchronously until the voltage detection head 10 contacts the two poles on the diamond semiconductor body 5, and then the voltage value of the diamond semiconductor body 5 is detected by the detection body 11;

[0037] The marking assembly includes a cylinder 12, a marking pen 13, a locking screw 14 and a tightening block 15. The cylinder 12 is fixedly mounted on the drive shaft 7, and the marking pen 13 is in contact with the inner wall of the cylinder 12.

The locking screw 14 is threadedly mounted on the cylinder 12, and the end of the locking screw 14 is fixedly connected to the tightening block 15, and the tightening block 15 is in contact with the marking pen 13.

[0050] S3: The voltage setting range value is set in advance. After the detection body 11 completes the detection of the voltage value of the diamond semiconductor body 5, if the voltage value is within the set range value, the controller 16 starts the drive motor 6, and the drive motor 6 drives the drive shaft 7 to rotate counterclockwise, so that the voltage detection head 10 is separated from the diamond semiconductor body 5, and then the diamond semiconductor body 5 is taken out;
