[0073] Embodiment 2:

[0074] See also Figure 1-9 This embodiment provides a multi-crucible PMN-PT crystal growth furnace station linkage control method based on the first embodiment, and the steps are as follows:

[0075] The first step is to place the down-conductor 2 with the PMN-PT crystal inside the carrying frame 5, and to position the down-conductor 2 with the aid of the transmission assembly 8 and the movable clamping plate 14;

[0076] In more detail, after the down-conductor 2 is placed in the corresponding mounting frame 5, the transmission motor A41 is started to drive the central shaft 39 to rotate. With the arrangement of the threaded sections 40 with opposite threads at two places on the central shaft 39, the two guide plates 38 can be used to drive the two air supply rods 36 to move synchronously into the air supply pipe 33, so as to transmit the gas in the air supply pipe 33 to the inside of the diverter pipe 35 through the transmission riser 34 with the help of the air supply sheet 37. The gas entering the diverter pipe 35 will be diverted to the air supply hose 31, and then injected into the push pipe 12 through the flow control box 18 and the transmission pipe 17. The gas entering the push pipe 12 will push the push sheet 15, causing the push rod 13 and the movable clamping plate 14 to approach the fixed clamping plate 11 until the down-conductor 2 is positioned between the movable clamping plate 14 and the fixed clamping plate 11.

[0077] The second step is to push the push frame 4 to move by the hydraulic cylinder 3, so that the down-conductor 2 is synchronously moved into the furnace chamber of the crystal growth furnace;

[0078] The third step is to adjust the position of the receiving bucket 46 by the rodless cylinder 9 and the transmission motor B44 so that the receiving bucket 46 corresponds to the position of the damaged downconductor 2;

[0079] In more detail, when any one of the down-conductors 2 is damaged and crystal generation is impossible, the rodless cylinder 9 is first started to drive the support frame 42 to move horizontally until the position of the receiving bucket 46 corresponds to the displacement of the damaged down-conductor 2, and then the transmission motor B44 is started to drive the transmission screw 43 to rotate, and under the connection between the transmission screw 43 and the displacement plate 45, the displacement plate 45 is displaced along the transmission screw 43 until the receiving bucket 46 reaches a suitable position below the carrying frame 5;

[0080] Step 4: start the corresponding electric push rod 30 to release the positioning of the damaged downconductor 2, so that the damaged downconductor 2 can be moved out of the furnace cavity alone by adjusting the receiving bucket 46;

[0081] In more detail, when the position of the receiving bucket 46 corresponds to the damaged down-conductor 2, the electric push rod 30 corresponding to the displacement of the receiving bucket 46 is started. Under the connection between the electric push rod 30 and the on-off plate 29, the on-off plate 29 can be driven to move downward, prompting the on-off plate 29 to move into the flow control box 18. With the continuous displacement of the on-off plate 29, the on-off plate 29 will contact the displacement rod A20 and press the displacement rod A20, prompting the displacement rod A20 to follow the displacement of the on-off plate 29. At the same time, under the connection between the displacement rod A20 and the linkage frame 23, when the displacement rod A20 is displaced, the linkage frame 23 can be used to synchronously pull the displacement rod B25, prompting the displacement rod B25 to drive the displacement sheet B26 to move;

[0082] When the on-off plate 29 moves to the bottom end of the flow control box 18, the displacement plate B26 will pass through the air outlet 28. At this time, the on-off plate 29 can be used to block the air supply hose 31 to prevent the gas in the air supply hose 31 from transmitting to the transmission pipe 17. At the same time, the gas in the transmission pipe 17 and the push pipe 12 will be discharged through the air outlet 28. When the movable clamping plate 14 moves toward the fixed clamping plate 11, the push piece 15 will drive the spiral spring A16 to deform. When the gas in the push pipe 12 and the transmission pipe 17 is discharged, the rebound of the spiral spring A16 can be used to push the movable clamping plate 14 away from the fixed clamping plate 11, so as to unlock the down pipe 2. The unlocked down pipe 2 will fall into the receiving bucket 46.

[0083] At the same time, the transmission motor C54 is started to drive the adjustment shaft 51 connected thereto to rotate. Under the connection of the two linked spur gears 53, the power of the transmission motor C54 can be transmitted to cause the two adjustment plates 52 to rotate simultaneously in opposite directions, and cooperate with the connection between the adjustment plates 52 and the guide through grooves 49, so that the two adjustment plates 52 drive the two guide vertical plates 48 to approach each other, thereby clamping the damaged down-conductor 2 through the two stabilizing clamps 47 to achieve the positioning of the down-conductor 2, and then start the transmission motor B44 to drive the displacement plate 45 to move downward, so that the damaged down-conductor 2 can be moved out of the furnace chamber of the crystal growth furnace without affecting the growth of other crystals.
