[0033] Please refer to Figures 1 to 7 and now a turntable structure for a silicon wafer dicing machine provided by the present utility model will be described. A turntable structure for a silicon wafer dicing machine includes a base 1, a rotating table 2, a workbench 3 and a clamping mechanism 4. The base 1 is used to be installed on the dicing machine. The base 1 is provided with a receiving groove 11, and a motor 5 is arranged in the receiving groove 11. The rotating table 2 is arranged in the receiving groove 11 and is located above the motor 5. The free end of the motor 5 is in transmission connection with the rotating table 2 for driving the rotating table 2 to rotate. The workbench 3 is arranged on the rotating table 2, and an installation groove 31 for installing a silicon wafer 7 and a blue film frame 6 is provided on the workbench 3. The number of the clamping mechanisms 4 is multiple, and the multiple clamping mechanisms 4 are arranged along the circumferential direction of the rotating table 2. The clamping mechanism 4 includes a clamping member 41 and a limiting member 42. The clamping member 41 is arranged on the rotating table 2, and the clamping member 41 has the freedom to clamp or loosen the blue film frame 6 along with the rotation of the rotating table 2. The limiting member 42 is arranged on the rotating table 2 for restricting the rotation of the clamping member 41.

[0034] For the turntable structure for a silicon wafer dicing machine provided in this embodiment, compared with the prior art, in the turntable structure for a silicon wafer dicing machine of the present utility model, during use, since the workbench 3 is arranged on the rotating table 2 and the workbench 3 is provided with the installation groove 31, after the silicon wafer 7 is pasted on the blue film frame 6, the silicon wafer 7 and the blue film frame 6 are then placed into the installation groove 31. Since the clamping member 41 is arranged on the rotating table 2 and the clamping member 41 has the freedom to clamp or loosen the blue film frame 6 along with the rotation of the rotating table 2, and at the same time the limiting member 42 is arranged on the rotating table 2, when controlling the clamping mechanism 4 to clamp the blue film frame 6, only need to rotate the clamping member 41, so that the clamping member 41 clamps the blue film frame 6, and at the same time the clamping member 41 is fixed by means of the limiting member 42, thereby preventing the clamping member 41 from rotating randomly. Since the motor 5 is installed in the receiving groove 11 of the base 1 and the free end of the motor 5 is in transmission connection with the rotating table 2 arranged in the receiving groove 11, after the silicon wafer 7 and the blue film frame 6 are fixed on the workbench 3 by means of the clamping mechanism 4, the motor 5 drives the rotating table 2 to rotate, so that the cutting tool makes a scratch on the silicon wafer 7. Since the number of the clamping mechanisms 4 is multiple and they are arranged along the circumferential direction of the rotating table 2, the clamping effect of the clamping mechanism 4 can be better by means of the multiple clamping mechanisms 4. In this way, by means of the rotation of the clamping member 41 to clamp or loosen the blue film frame 6 located in the receiving groove 11 and using the limiting member 42 to restrict the rotation of the clamping member 41, the blue film frame 6 is fixed in the receiving groove 11, without the need for the staff to rotate bolts, greatly shortening the time required for fixing the silicon wafer 7, thereby improving the work efficiency.

One end of the clamping member 41 is rotatably connected to the rotating table 2, and the other end is located above the workbench 3 for clamping or loosening the blue film frame 6. Since the clamping member 41 is set to have an L-shaped structure and one end of the clamping member 41 is rotatably connected to the rotating table 2, when controlling the rotation of one end of the clamping member 41, the other end of the clamping member 41 clamps or loosens the blue film frame 6 as the clamping member 41 rotates, thereby clamping or loosening the silicon wafer 7.

The elastic member 432 is arranged in the pressing groove 411 and is fixedly connected to the pressing block 431 and the inner wall of the pressing groove 411 at both ends respectively. When the clamping member 41 rotates to clamp the blue film frame 6, the pressing block 431 contacts the blue film frame 6, and as the clamping member 41 rotates, the pressing block 431 moves in the pressing groove 411 in the direction away from the blue film frame 6 and compresses the elastic member 432. Then, the elastic member 432 reversely pushes the pressing block 431 to move by means of the elastic force, so that the pressing block 431 presses on the blue film frame 6, thereby increasing the clamping effect of the clamping member 41 by means of the elastic member 432 and the pressing block 431.
