[0001] The utility model relates to the technical field of semiconductor processing, in particular to a semiconductor grain screening device. Background Art
[0002] Semiconductor grains are the core part of thermoelectric coolers. Each grain is sometimes composed of several sub-grains with slightly different orientations. During the processing, the grains need to be screened. However, manual selection is usually used, and screening with the assistance of a microscope is required when necessary. This method is inefficient, labor-intensive, and the quality cannot be guaranteed. Utility Model Content
[0003] The utility model aims to provide a semiconductor crystal grain screening device in view of the defects and shortcomings of the prior art.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a semiconductor grain screening device, including a screen cylinder, and its innovation lies in: the screen cylinder is arranged horizontally, and a left closed plate and a right closed plate are respectively arranged at the left and right ends of the screen cylinder, a rotating shaft is rotatably arranged between the left closed plate and the right closed plate, and the rotating shaft is driven by a motor, connecting rods are arranged on the left and right sides of the rotating shaft, and a stirring plate is arranged between the connecting rods, a feed port is arranged on the upper part of the left closed plate, a support leg is hingedly arranged at the lower part of the left closed plate, a discharge port is arranged at the lower part of the right closed plate, a hydraulic cylinder is hingedly arranged at the bottom of the discharge port, and the bottom of the hydraulic cylinder is hinged on the base, and a recovery box is placed below the screen cylinder.
