In order to meet the requirements of large-scale production, semiconductor chip manufacturers need efficient and accurate sorting equipment to improve production efficiency and product quality.

[0003] Semiconductor chip sorting machines mainly consist of conveyor belts, testers, etc. Chips are fed to the conveyor belt by the feeding device, first passing through the inspection station, where a light source-assisted camera takes pictures. The images are transmitted to the control system for analysis of the appearance. Then, the control system classifies the chips according to preset rules based on the two inspection results. Finally, the sorting execution mechanism places the chips into the corresponding containers according to the instructions, completing the sorting and ensuring that the chips are classified according to quality.

[0004] In existing technologies, some screening devices can only perform some basic parameter tests and simple sorting on chips, which is slow and cannot meet the complex needs of modern chip production. Therefore, a semiconductor chip sorting machine is proposed to solve the above problems. Utility Model Content

The first motor 306 drives the transmission threaded column 304 to rotate. The sliding columns 3010 cause the fixed limiting block 3011 to slide. The fixed limiting block 3011 is slidably connected to the outer side of the sliding column 3010. A sliding rack 309 is slidably connected to the inner side of the fixed limiting block 3011. The outer side of the sliding rack 309 meshes with the outer side of the drive gear 308. The connection and drive gear 308 are used to drive the sliding rack 309 to slide inside the fixed limit block 3011 to adjust its position. The top of the base plate 301 is fixedly connected to the support plate 302. The top of the support plate 302 is fixedly connected to the limit post 303. The support plate 302 is used to connect the base plate 301 and the limit post 303. The limit post 303 is used to limit the position of the transmission thread post 304. One side of the limit post 303 is rotatably connected to one side of the transmission thread post 304, that is, the side away from the support plate 305.

One side of the fixed connecting plate 901 is fixedly connected to the outside of the support column 6. A rotating rod 905 is rotatably connected to the outside of the fixed connecting plate 901. The rotating rod 905 pushes a rotating connecting rod 906 to swing. The rotating connecting rod 906 pushes a sliding block 907. A spring is provided on the inner side of the rotating connecting rod 906 to make it swing back and forth. A second motor 902 is fixedly connected to the outside of the fixed connecting plate 901. The support column 6 is fixedly connected to the outer side of the rotating rod 905 to drive the rotation. The bottom two sides of the slide rail 903 are fixedly connected to the industrial camera 904, which is used to detect and photograph the chip.

[0029] Working principle: The motor 902 drives the rotating rod 905 to rotate through the fixed connecting plate 901. The protruding cylinder on the outside of the rotating rod 905 pushes the protruding bar of the rotating connecting rod 906 to swing back and forth through the spring on the outside of the rotating connecting rod 906, thereby pushing the protruding block on the top of the sliding block 907 to slide inside the slide rail 903. After being illuminated by the industrial camera 904, the data is transmitted to the display screen 8 on the outside of the support column 6 for display. The rotation speed of the rotating rod 905 is controlled to control the sliding speed of the sliding block 907 inside the slide rail 903. The semiconductor chip is moved from the screening placement plate 5 to the light source irradiation plate 4 for irradiation and screening through the suction cup 908.

[0030] Driven by motor 306, the transmission threaded column 304 restricted by support plate 305 rotates. The rotation of the transmission threaded column 304 is further transmitted to the transmission gear 307, causing it to rotate as well. The rotation of the transmission gear 307 then drives the drive gear 308 to rotate as well. Under the precise restriction of the fixed limit block 3011, the rotation of the drive gear 308 causes the sliding rack 309 to slide inside the fixed limit block 3011, thereby adjusting the position of the light source illumination plate 4 and the screening placement plate 5, thus facilitating the screening process.
