[0037] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] As Figures 1-4 shown, an automatic material taking device for a crystal growth furnace includes a furnace body 1, a connecting column 2, a crystal bar 3, a sleeve 4, a connecting plate 5, a first driving mechanism, a second driving mechanism and a connecting mechanism. A hole is provided at the top of the furnace body 1; the connecting column 2 is passed through the hole at the top of the furnace body and can move up and down relative to the hole, and one end of the connecting column extends into the furnace body; the crystal bar 3 is fixed to the end of the connecting column; the sleeve 4 is detachably connected to the connecting column through the connecting mechanism; the connecting plate 5 is fixed to the top of the sleeve; the first driving mechanism can drive the connecting plate to move up and down; the second driving mechanism can drive the connecting plate to rotate by a certain angle.

[0039] Specifically, the connecting mechanism includes a limit baffle 61, a locking rod 62, a locking block 63, a fixing plate 64 and a tension spring 65. The limit baffle 61 is fixed to the outer wall of the connecting column and is located above the furnace body; the locking rod 62 is uniformly passed through the sleeve, and the sleeve is provided with a round hole for the locking rod to pass through; the locking block 63 is fixed to the end of the locking rod, and a clamping groove 21 is provided on the outer wall of the connecting column, and the clamping groove can be used for the locking block to be inserted; a groove 41 matching with the locking block is provided on the inner wall of the sleeve; the fixing plate 64 is fixed to the outer wall of the locking rod; the tension spring 65 is sleeved on the locking rod, one end of which is fixed to the fixing plate and the other end is fixed to the outer wall of the sleeve; arc-shaped curved surfaces are provided at the end of the sleeve and the bottom of the locking block. Then when it is necessary to take out the crystal, the sleeve is aligned with the connecting column, and then the sleeve is moved down by the first driving mechanism. During the downward movement of the sleeve, the end of the connecting column will squeeze the locking block into the groove. When the connecting column is inserted into the top of the sleeve, the locking block is exactly aligned with the clamping groove, and the tension spring will pull the locking rod to move, and then move the locking block into the clamping groove, so that the sleeve and the connecting column are connected. Then the sleeve is moved up by the first driving mechanism to drive the crystal bar out of the furnace body. When the crystal bar is completely removed from the furnace body, the connecting plate is rotated by the second driving mechanism to adjust the position of the crystal bar for subsequent operations. Then the locking rod is pulled to move the locking block out of the clamping groove, and the connecting column can be taken out of the sleeve, and the material taking is very convenient and facilitates subsequent processing.

[0040] Specifically, the first driving mechanism includes a fixing frame 71, a lead screw 72, a driving block 73, a limiting post 74 and a first driving member 75. The two ends of the lead screw 72 are respectively rotatably connected to the fixing frame. The driving block 73 is screwed onto the lead screw, is provided with a threaded hole, and is fixedly connected to the connecting plate. The two ends of the limiting post 74 are respectively fixed to the fixing frame, and the driving block is provided with a limiting hole for the limiting post to pass through. The first driving member 75 is a motor, which is fixed to the fixing frame, and its output shaft is connected to the end of the lead screw. Then, starting the first driving member to drive the lead screw to rotate can drive the driving block to move up and down on the lead screw, and further drive the connecting plate to move up and down. The second driving mechanism includes a base 81, a supporting foot 82, a turntable 83, a limiting connecting plate 85 and a second driving member 84. The supporting foot 82 is fixed to the bottom of the base. The second driving member 84 is a motor, which is fixed to the base. The turntable 83 is fixed to the output shaft of the second driving member and is fixedly connected to the fixing frame. One side of the limiting connecting plate 85 is fixed to the base, and the other side is fixed to the outer wall of the furnace body. Then, starting the second driving member can drive the turntable to rotate, and further drive the fixing frame to rotate, thereby driving the connecting plate to rotate.

[0041] In other embodiments, the connecting mechanism further includes a connecting ring 91, a driving column 92, a pushing block 93, a push rod 94 and a protection component. The connecting ring 91 is rotatably connected to the outer wall of the sleeve. The driving column 92 is fixed to the locking rod. The pushing blocks 93 are evenly fixed to the outer wall of the connecting ring. The number of the pushing blocks is the same as that of the locking rods, and the pushing blocks are provided with inclined surfaces, and the inclined surfaces can contact the driving column. The push rod 94 is fixed to the connecting ring. Then, when it is necessary to move the locking block out of the card slot, the connecting ring can be rotated through the push rod. During the process of the connecting ring driving the pushing block to rotate, the pushing block will squeeze the driving column, and under the guidance of the inclined surface of the pushing block, all the locking blocks can be simultaneously moved out of the card slot, and the disassembly is very convenient. The protection component includes an installation hole 951, an elastic member 952, a top rod 953 and a ball 954. The installation hole 951 is opened on the outer wall of the sleeve. The elastic member 952 is a spring, one end of which is fixed to the bottom of the installation hole. One end of the top rod 953 is fixed to the end of the elastic member, and it can slide relative to the inner wall of the installation hole. The ball 954 is rotatably connected to the end of the top rod. A limiting groove matched with the ball is provided on the inner wall of the connecting ring. When the lowest and highest points of the inclined surface of the pushing block contact the driving column, the ball is exactly aligned with the limiting groove, which can prevent misoperation.
