The first motor 11 is a prior art and can be selected according to actual needs for corresponding models and specifications.

[0032] On the top of the workbench 22, four rotating trays are evenly installed. Each of the four rotating trays includes a second motor 19, and the second motor 19 is fixedly installed inside the workbench 22. The driving shaft of the second motor 19 penetrates through the workbench 22 and is fixedly connected to a crucible tray 21. The second motor 19 is a prior art and can be selected according to actual needs for corresponding models and specifications. A plain bearing is jointly installed between the crucible tray 21 and the workbench 22, which has a supporting effect on the crucible tray 21 and also reduces the rotational resistance of the crucible tray 21.

[0033] The outer surfaces of the four rotating trays are all provided with annular seats 5. Four through grooves penetrating to the interior are opened at the tops of the four annular seats 5. The inner walls on both sides of the sixteen grooves are jointly connected with sliding seats 20 in a sliding manner.

Moreover, the third motor 24 is fixedly installed on the top of the annular seat 5. The drive shaft of the third motor 24 penetrates through the annular seat 5 and is fixedly connected with a small gear 25. One side of the outer surface of the small gear 25 is meshed with a large gear 17, and the large gear 17 is rotatably connected with the inner wall of the annular seat 5.

[0034] A drain pipe 2 is fixedly penetrated on one side of the outer surface of the housing 3.

[0035] Working principle:

[0036] Step 1: First, place the crucible preform on the crucible tray 21 at the loading station with the crucible opening upward. Then, the corresponding third motor 24 is started and runs. The third motor 24 drives the small gear 25 to rotate. The small gear 25 drives the large gear 17 to rotate. The large gear 17 drives the Archimedean spiral groove 18 to rotate. The four sliding seats 20 are driven to approach synchronously along the grooves through the Archimedean spiral groove 18. The sliding seats 20 drive the vertical rods 23 to approach the crucible preform until the crucible is positioned by the auxiliary rollers 8.

[0037] Step 2: The first motor 11 operates, driving the driving gear 10 to rotate. The driving gear 10 drives the working station frame 22 to rotate through the driven gear 9. After the working station frame 22 rotates 45 degrees, it pauses for a set time, then operates again, rotates 45 degrees, and then pauses (this pause time is for cutting and processing). At this time, the empty crucible tray 21 moves to the loading station, and the operation of Step 1 can be carried out. This process is repeated. When the crucible preform to be processed moves below the industrial robotic arm 6, the industrial robotic arm 6 and the water jet cutting head 7 cooperate to perform the cutting operation (the industrial robotic arm 6 determines the cutting position and angle, and the water jet cutting head 7 cooperates with an external ultra-high pressure water jet generator to achieve the cutting function). During the cutting, the corresponding second motor 19 operates, driving the crucible tray 21 to rotate. While the crucible tray 21 rotates, it drives the crucible preform to rotate (the rotation principle is that the crucible preform has a certain self-weight, increasing the friction with the crucible tray 21, so it can drive its rotation), thus realizing circular cutting. After the cutting is completed, the second motor 19 stops operating, and the industrial robotic arm 6 drives the water jet cutting head 7 to reset;

[0038] Step 3: When the cut crucible preform moves below the lifting cylinder 4, the lifting cylinder 4 drives the mounting seat 14 and the double-acting cylinder 12 to descend until the set position is reached. Then, the double-acting cylinder 12 drives the two clamping plates 13 to approach each other through the U-shaped rod 16 until the ring cut from the crucible preform is clamped and fixed. Then it resets. When the working station frame 22 rotates 45 degrees again, the clamping assembly releases the fixation of the ring, and the ring falls under the action of gravity (a collection box should be placed below).

[0039] It should be noted that in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the industrial robotic arm 6, the first motor 11, the second motor 19, the third motor 24, the external ultra-high pressure water jet generator, the solenoid valve, and the air compressor, which is convenient for controlling the overall operation. The specific data analysis and processing involved to further realize the control function are the method contents that those skilled in the art can achieve based on common knowledge. These method contents are not within the scope of this solution. The above description only explains the beneficial effects that can be achieved by the improvement of this hardware structure in combination with common knowledge.
