Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Specifically, the flipping mechanism 5 includes a motor 51, an inner rod 52, a sleeve 53, a connecting frame 54, and a clamping mechanism 55. The inner rod 52 is fixedly connected to the rotating shaft of the motor 51. The sleeve 53 is provided on the outer side of the inner rod 52. The connecting frame 54 is fixedly connected to the end of the sleeve 53 away from the motor 51. The clamping mechanism 55 is provided on the top of the connecting frame 54.

[0025] By adopting the above technical solution, motor 51 can drive inner rod 52 to rotate, and at the same time drive sleeve column 53 to rotate. When quartz wafer 6 is placed in connecting frame 54, it can drive quartz wafer 6 to rotate. Clamping mechanism 55 can fix quartz wafer 6 from both ends.

[0026] Specifically, the clamping mechanism 55 includes an internally threaded post 551, a long bolt 552, a bearing 553, and a pressure plate 554. The bottom of the internally threaded post 551 is fixedly connected to the connecting frame 54. The long bolt 552 is provided on the inner side of the internally threaded post 551. The bearing 553 is provided at the bottom of the long bolt 552. The pressure plate 554 is provided on the outer side of the bearing 553.

[0027] By adopting the above technical solution, the long bolt 552 is turned from above. The long bolt 552 will rise and fall in the internal thread column 551 due to the spiral movement. The rotation of the long bolt 552 in the bearing 553 can make the pressure plate 554 move down and then press against the quartz crystal 6 to achieve the clamping effect.

[0028] Specifically, the inner rod 52 has a groove 56 on its side, and a fixing bolt 57 is provided on the outer side of the sleeve 53 near the groove 56. A nut 58 is provided on the outer side of the fixing bolt 57.

The electric slide rail 10 drives the hydraulic cylinder 7 to move. The hydraulic cylinder 7 causes the drive motor 12 and the grinding wheel 11 to move up and down. The drive motor 12 causes the grinding wheel 11 to rotate, polishing the surface of the quartz crystal 6. When it is necessary to flip the quartz crystal 6, the first motor 51 can drive the inner rod 52 to rotate, and at the same time drive the sleeve column 53 to rotate. When the quartz crystal... When the quartz crystal 6 is placed inside the connecting frame 54, it can rotate the quartz crystal 6. Tightening the long bolt 552 from above will cause the long bolt 552 to rise and fall in the internal threaded column 551 due to the spiral motion. Rotating the long bolt 552 in the bearing 553 will allow the pressure plate 554 to move down and then press against the quartz crystal 6 to achieve a clamping effect. Pulling the sleeve column 53 outward can adjust the distance between the connecting frame 54 and the quartz crystal 6. Tightening the fixing bolt 57 with the nut 58 can fix the sleeve column 53 and the inner rod 52. The connecting frame 54 can be rotated by the motor 51, which can flip the quartz crystal 6, saving manpower.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the disassembly and assembly mechanism 8 includes a housing 81, a fixing rod 82, a limiting plate 83, a spring 84, a round hole 85, a hexagonal groove 86, and a hexagonal block 87. The top of the housing 81 is fixedly connected to the fixing frame 13. The fixing rod 82 is provided on the inner side of the housing 81. The upper outer end of the fixing rod 82 is fixedly connected to the limiting plate 83. The bottom of the limiting plate 83 is provided with a spring 84. The bottom of the grinding wheel 11 has a round hole 85. The shaft of the drive motor 12 is fixedly connected to the hexagonal block 87. The top of the grinding wheel 11 has a hexagonal groove 86 on the side below the hexagonal block 87.

[0033] By adopting the above technical solution, the drive motor 12 rotates the grinding wheel 11 through the cooperation of the hexagonal block 87 and the hexagonal slot 86. When disassembling or installing the grinding wheel 11, hold the fixing rod 82 and pull it down. The limiting plate 83 will compress the spring 84. At this time, the grinding wheel 11 can be taken out from the fixing frame 13. Insert the new grinding wheel 11 into the hexagonal block 87, release the fixing rod 82, and under the action of the spring 84, the fixing rod 82 will be inserted into the round hole 85.

[0034] Specifically, a circular groove 88 is provided on the side of the top of the grinding wheel 11 near the hexagonal groove 86, and a slide rod 89 is provided on the inner side of the circular groove 88. The top of the slide rod 89 is fixedly connected to the fixing frame 13.

[0035] By adopting the above technical solution, when the grinding wheel 11 rotates, the slide bar 89 will slide in the circular groove 88, which can make the grinding wheel 11 rotate more smoothly.

[0036] In this embodiment, the drive motor 12 rotates the grinding wheel 11 through the cooperation of the hexagonal block 87 and the hexagonal slot 86. When disassembling or installing the grinding wheel 11, hold the fixing rod 82 and pull it down. The limiting plate 83 will compress the spring 84. At this time, the grinding wheel 11 can be taken out from the fixing frame 13. Insert the new grinding wheel 11 into the hexagonal block 87, release the fixing rod 82. Under the action of the spring 84, the fixing rod 82 will be inserted into the round hole 85. When the grinding wheel 11 rotates, the sliding rod 89 will slide in the round slot 88, which can make the grinding wheel 11 rotate more smoothly. By pulling the fixing rod 82, the grinding wheel 11 can be disassembled and installed at any time, improving work efficiency.

[0037] The structure and operating principle of the mounting plate 1, sliding assembly 2, slide table 3 and grinding wheel 11 in this utility model have been disclosed in a quartz wafer grinding device disclosed in Chinese patent application number CN202122635353.7.

[0038] The working principle and usage process of this utility model are as follows: When using this utility model, motor 1 (51), electric slide rail 10, drive motor 12, and motor 2 (15) are connected to an external power source. The sliding assembly 2 moves the base 14 and motor 2 (15) on the mounting plate 1 via the slide table 3. Motor 2 (15) drives the U-shaped frame 4 and the quartz crystal 6 to rotate. The electric slide rail 10 drives the hydraulic cylinder 7 to move, and the hydraulic cylinder 7 causes the drive motor 12 and the grinding wheel 11 to move up and down. The drive motor 12 causes the grinding wheel 11 to rotate, polishing the surface of the quartz crystal 6. When the quartz crystal 6 needs to be flipped, motor 1 (51) drives the inner rod 52 to rotate, simultaneously driving the sleeve column 53 to rotate. When the quartz crystal 6 is placed in the connecting frame 54, it can rotate, allowing the long bolt 552 to be turned from above. The long bolt 552 will rise and fall within the internal thread column 551 due to spiral motion. Rotating the long bolt 552 within the bearing 553 allows the pressure plate 554 to move downwards. The sleeve 53 is held against the quartz wafer 6 to achieve a clamping effect. Pulling the sleeve 53 outward can adjust the distance between the connecting frame 54 and the quartz wafer 6. Tightening the fixing bolt 57 with the nut 58 can fix the sleeve 53 and the inner rod 52. The motor 11 drives the connecting frame 54 to rotate, which can flip the quartz wafer 6, saving manpower. The drive motor 12 rotates the grinding wheel 11 through the cooperation of the hexagonal block 87 and the hexagonal slot 86. When disassembling or installing the grinding wheel 11, hold it... Pulling down the fixing rod 82 will compress the spring 84 by the limiting plate 83. At this time, the grinding wheel 11 can be taken out from the fixing frame 13, and the new grinding wheel 11 can be inserted into the hexagonal block 87. Loosening the fixing rod 82 will cause the fixing rod 82 to be inserted into the round hole 85 under the action of the spring 84. When the grinding wheel 11 rotates, the sliding rod 89 will slide in the round groove 88, which can make the grinding wheel 11 rotate more smoothly. By pulling the fixing rod 82, the grinding wheel 11 can be disassembled and assembled at any time, improving work efficiency.
