[0002] At present, single crystal silicon is a relatively active non-metallic element, an important component of crystal materials, and is at the forefront of the development of new materials. Its main uses are as a semiconductor material and in the use of solar photovoltaic power generation and heating.

[0003] Current technology often uses circular horizontal parallel rotary engraving and cutting machines for linear cutting, mainly using diamond wire to cut brittle and hard materials such as stone and silicon crystal. The cutting wheel system consists of multiple cutting wheels, and the diamond wire is a closed circular cutting wire structure and is wound in the wire groove on the cutting wheel system. After the cutting wheel system rotates, it drives the diamond wire to do linear motion.

[0004] During cutting, the single crystal silicon is generally glued to the turntable of the engraving and cutting machine by hot melt glue or other soluble glue, and then linear cutting is performed. In the prior art, the turntable and the engraving machine are not detachable, and cutting cannot be performed during loading and unloading.

[0005] Therefore, in order to improve production efficiency, it is urgent to improve the turntable structure. Utility Model Content

The pneumatic rotary chuck and the protective cover are both fixed on the engraving machine. The protective cover is arranged on the pneumatic rotary chuck. A clearance hole is opened in the middle of the protective cover. The clearance hole is coaxially arranged with the center of the disk body of the pneumatic rotary chuck. The turntable comprises an integrally formed table body and a connecting column. The pneumatic rotary chuck can clamp and fix the connecting column.

[0009] Preferably, in order to ensure that the turntable can be clamped by the pneumatic rotary chuck, a claw of the pneumatic rotary chuck is provided with an arcuate surface on one side corresponding to the connecting column, the arcuate surface has anti-slip grooves, and the surface of the connecting column is wrapped with a rubber pad.

[0010] Preferably, in order to ensure the smooth rotation of the turntable, a plurality of guide support wheels are evenly arranged on the upper surface of the protective cover, and the plurality of guide support wheels are evenly distributed on the protective cover in a ring shape, and the table body can contact the guide support wheels.

[0011] Preferably, a retaining ring is integrally formed on the protective cover, and the retaining ring is arranged on the top of the clearance hole.

[0012] By adopting the above technical solution, the retaining ring can play a role in blocking the lubricating liquid and prevent excessive lubricating liquid from entering the protective cover.

[0013] Preferably, in order to facilitate the insertion of the turntable from the clearance hole to the pneumatic rotary chuck, the bottom edge of the connecting column is chamfered.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. The turntable is easy to load and unload. The turntable is fixed and driven by a pneumatic rotary chuck, which can not only realize the automatic centering of the turntable, but also has a reliable fixing effect;

[0016] 2. When the turntable mechanism for an engraving machine that is easy to load and unload is used in an engraving and cutting machine, the single crystal silicon to be cut can be fixed on the turntable in advance. After the cutting is completed, only the turntable needs to be replaced, which saves the time for replacing the single crystal silicon and can improve the production efficiency.

[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] The embodiment of the present application discloses a turntable mechanism for an engraving machine that is convenient for loading and unloading the turntable. Figure 1-2, including a pneumatic rotary chuck 1, a protective cover 2 and a turntable 3. The pneumatic rotary chuck 1 and the protective cover 2 are both fixed on the engraving machine. The protective cover 2 is arranged on the pneumatic rotary chuck 1. A clearance hole 21 is opened in the middle of the protective cover 2. The clearance hole 21 is coaxially arranged with the center of the disk body of the pneumatic rotary chuck 1. The turntable 3 includes an integrally formed table body 31 and a connecting column 32. The pneumatic rotary chuck 1 can clamp and fix the connecting column 32. The bottom edge of the connecting column 32 is chamfered.

[0022] When the turntable 3 needs to be removed, the turntable 3 can be removed by simply loosening the pneumatic rotary chuck 1 , and vice versa, the turntable 3 can be fixed by inserting it into the pneumatic rotary chuck 1 .

[0023] Reference Figure 2 In order to ensure that the turntable 3 can be clamped by the pneumatic rotary chuck 1, a curved surface 11 is provided on one side of the pneumatic rotary chuck 1 corresponding to the connecting column 32, and the curved surface 11 has anti-slip grooves, and the surface of the connecting column 32 is wrapped with a rubber pad.

[0024] Reference Figure 2 In order to ensure the smooth rotation of the turntable 3, a plurality of guide support wheels 22 are evenly arranged on the upper surface of the protective cover 2. The plurality of guide support wheels 22 are evenly distributed on the protective cover 2 in a ring shape, and the platform body 31 can contact the guide support wheels 22.

[0025] Reference Figure 2 A retaining ring 23 is also integrally formed on the protective cover 2, and the retaining ring 23 is arranged on the top of the clearance hole 21. The retaining ring 23 can block the lubricating liquid and prevent excessive lubricating liquid from entering the protective cover 2 (most of the lubricating liquid has been separated from the turntable 3 under the action of centrifugation).

[0026] The implementation principle of the turntable mechanism for an engraving machine that is convenient for loading and unloading the turntable in the embodiment of the present application is as follows:

[0027] In actual use, there are multiple turntables 3. When the engraving and cutting machine is working, the staff can glue and fix the single crystal silicon on several turntables 3 respectively for preparation. After the engraving and cutting machine is finished cutting, the staff only needs to remove the turntable 3 on the engraving and cutting machine, and then replace it with the turntable 3 glued with the single crystal silicon, which saves the time of replacing the single crystal silicon, thereby greatly improving the production efficiency;
