Description

Technical Field

[0001] The utility model relates to the technical field of a turntable machine, in particular to an improved turntable machine. Background Art

[0002] In the semiconductor industry, for the crystal grains cut after the wafer processing is completed, these crystal grains are tiny plate structures, and the opposite two side surfaces of the plate structure are a P surface and an N surface respectively. Since the characteristics of these two side surfaces are different, when the crystal grains are processed subsequently onto other components such as circuit boards, they need to be placed with a correct orientation to produce the correct performance. This processing flow of identifying the two side surfaces of the crystal grains and turning them to the correct surface is achieved through a turntable. The turntable has a plurality of crystal grain holes. The user holds the turntable by hand and sprinkles the crystal grains on the turntable and then starts to gently shake it. Since the crystal grain holes have a special groove shape, when the crystal grains fall into the crystal grain holes during the shaking process, if they enter the crystal grain holes with the correct orientation (N surface facing down), they can cooperate with the groove shape and be stably arranged in the crystal grain holes. However, if they enter the crystal grain holes with the incorrect orientation (P surface facing down), they will not be able to be stably arranged in the crystal grain holes because their shapes do not match the shape inside the crystal grain holes. Furthermore, they will be shaken out of the crystal grain holes again during the continuous shaking process. Through this process of shaking the crystal grains, after the shaking is completed, the crystal grains can all be arranged in the crystal grain holes with the correct orientation, achieving the function of turning the crystal grains to the correct orientation.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1-5 , an improved turntable machine, including a base 1, a U - shaped support rod 2 is installed on the base 1, an equipment table 3 is installed on the U - shaped support rod 2, a drive mechanism 4 is installed on the equipment table 3, two relatively arranged open boxes 5 are connected to the drive mechanism 4, a servo motor 6 is installed on the U - shaped support rod 2, a threaded rod 7 is connected to the output shaft of the servo motor 6, both ends of the threaded rod 7 are respectively rotatably connected to the U - shaped support rod 2 and the base 1, and a plurality of threaded blocks 8 are threadedly connected to the threaded rod 7, a sieve plate 9 is rotatably connected to each of the plurality of threaded blocks 8, and the sieve plate 9 is located between the two open boxes 5.

[0023] When the turntable machine is in use, first start the servo motor 6. The rotation of the servo motor 6 drives the threaded rod 7 to rotate synchronously, so that a number of threaded blocks 8 threaded on the threaded rod 7 move, and then drive a number of sieve plates 9 to move. When the lowermost sieve plate 9 moves to a position flush with the two open boxes 5, turn off the servo motor 6 so that the sieve plate 9 stays in this position. Then start the driving mechanism 4. The driving mechanism 4 drives the two open boxes 5 to rotate reciprocally in a small amplitude, so that the grains in the open boxes 5 fall into the grooves on the sieve plate 9 during the shaking of the turntable machine, so as to achieve the purpose of collecting the grains with the same side facing down. After the grooves on the sieve plate 9 are all filled with grains, keep the open box 5 tilted to one side, and continue to operate the servo motor 6 to make the sieve plate 9 filled with grains move downward, so that the sieve plate 9 above it moves to the position of the open box 5. Then operate the driving mechanism 4 to continue the work of grain induction and collection. By arranging a plurality of sieve plates 9 in the turntable machine, when one sieve plate 9 is all filled with grains, move the sieve plate 9 downward and move the sieve plate 9 on this sieve plate 9 to an appropriate position, so as to continuously collect the grains, avoiding the situation that the sieve plate 9 needs to be manually replaced repeatedly after being filled with grains, ensuring the correctness of grain induction and collection, effectively reducing the labor cost and improving the work efficiency.

[0024] Specifically, in this embodiment, a moving groove 10 is opened on the equipment table 3. The size of the moving groove 10 is larger than the size of the sieve plate 9, so that the sieve plate 9 can pass through the equipment table 3 through the moving groove 10 when moving, so that the sieve plate 9 can move normally, and then complete the height adjustment of the sieve plate 9, so that each sieve plate 9 can move to a height flush with the open box 5.

[0025] Specifically, in this embodiment, a sliding rod 11 is installed between the base 1 and the U-shaped support rod 2. A number of sliders 12 are slidably installed on the sliding rod 11. One ends of the number of sliders 12 away from the sliding rod 11 are respectively rotatably connected to the corresponding sieve plates 9, so that one end of the sieve plate 9 away from the threaded rod 7 can be slidably connected to the sliding rod 11 through the slider 12, thereby providing support for the sieve plate 9 and further improving the stability of the sieve plate 9.

[0026] Specifically, in this embodiment, rotating shafts 13 are slidably installed on both sides of the number of sieve plates 9. One ends of the two rotating shafts 13 installed on the same sieve plate 9 away from each other are respectively rotatably connected to the corresponding threaded blocks 8 and sliders 12, so that the sieve plate 9 can be rotatably installed on the corresponding threaded block 8 through the rotating shaft 13, so as to ensure that the sieve plate 9 is connected to the threaded rod 7 and can rotate synchronously with the open box 5.

[0027] Specifically, in this embodiment, connecting blocks 14 are installed on both sides of several sieve plates 9. Connecting grooves 15 are formed at one ends of several rotating shafts 13 close to the sieve plates 9. The connecting blocks 14 are slidably installed in the corresponding connecting grooves 15, so that the sieve plates 9 can be slidably connected to the rotating shafts 13 through the connecting blocks 14 at both ends thereof, thereby completing the lifting of the sieve plates 9 and the processing of the grains. At the same time, the processing requirements for different specifications of grains can be met by replacing the sieve plates 9.

[0028] Specifically, in this embodiment, L-shaped connecting rods 16 are installed on both sides of the two open boxes 5. One ends of adjacent two L-shaped connecting rods 16 close to each other are both installed with telescopic rods 17. Clamping blocks 18 are installed on the telescopic rods 17. The two clamping blocks 18 close to each other are in contact with the corresponding rotating shafts 13, so that the rotating shafts 13 can be limited by the clamping blocks 18, so that the sieve plates 9 are connected to the two open boxes 5 through the rotating shafts 13. When the open boxes 5 move, the corresponding sieve plates 9 can be driven to move synchronously, thereby completing the collection of the grains.

[0029] Specifically, in this embodiment, a sensor 19 is installed on one of the open boxes 5. The sensor 19 is electrically connected to the driving mechanism 4 and the servo motor 6, so that the sensor 19 can monitor the sieve plate 9. When one of the sieve plates 9 is filled with grains, the driving mechanism 4 and the servo motor 6 can be triggered to work, thereby performing the next round of grain collection, effectively improving the working efficiency.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
