[0052] A first motor 7 is installed on the moving member 6. A clamping member 8 is installed at the output end of the first motor 7. The clamping member 8 includes a fixed seat 81 connected to the output end of the first motor 7. A cavity structure 82 is provided inside the fixed seat 81. A pair of movable holes 83 are opened on the side wall of one side of the cavity structure 82. A first gear 84 is installed in each of the pair of movable holes 83. A clamping arm 85 is installed at the upper end of each of the pair of first gears 84. The clamping arm 85 is composed of a clamping arm and a connecting arm. The clamping arm is made of a high-temperature resistant material, and the connecting arm is made of a heat-insulating material.

The clamping arm is made of a high-temperature resistant material and can withstand a high-temperature environment; the connecting arm is made of a heat-insulating material to prevent heat from being transferred to other parts of the clamping mechanism. The two-way air cylinder 86 realizes the opening and closing of the clamping arm 85 by pushing the first toothed plate 87 to engage with the first gear 84, ensuring the stability and safety of the sample during the movement and melting process, and at the same time improving the adaptability and flexibility of the clamping member 8.

[0054] A placement plate 9 is provided on the installation box 12. A transmission member 10 is provided between the placement plate 9 and the moving member 6. The transmission member 10 includes a fixing plate 1001 installed on the outer wall of the installation box 12.

A second toothed plate 1007 meshing with the second gear 1006 is installed on the outside of the moving seat 63;

[0055] The placement plate 9 is used for temporarily placing samples. The transmission member 10 realizes the rotation of the placement plate 9 through the transmission of the transmission wheels 1004 and the belt 1005, and the meshing of the second gear 1006 and the second toothed plate 1007, avoiding the placement plate 9 from blocking the movement of the moving seat 63 and improving the flexibility and operation efficiency of the entire automatic loading and unloading mechanism; When the moving seat 63 moves towards the melting sample machine body 1, the second toothed plate 1007 moves synchronously. Driven by the second toothed plate 1007, the second gear 1006 rotates. Driven by the transmission wheels 1004 and the belt 1005, the placement plate 9 rotates through the rotating shaft 1002. When the moving seat 63 returns to the initial position, the second toothed plate 1007 drives the second gear 1006 to rotate in the reverse direction, and the placement plate 9 returns to the initial position.

The first electric push rod 1003 is used to control the lifting of the storage plate 1004. The water-permeable holes 1005 provided on the surface of the storage plate 1004 contribute to the uniform distribution and rapid heat dissipation of the cooling medium, improving the cooling efficiency of the samples, ensuring that the samples can be quickly cooled to a suitable analysis temperature, and preventing the high-temperature samples from affecting the conveying device. The design of the cooling table 11 also takes into account the convenience and safety of operation. Through the control of the electric push rod, the stable lifting of the storage plate 1004 is achieved.

[0066] Meanwhile, the second electric push rod 101 starts, pushing the third toothed plate 102 to rotate the third gear 104. The rotation of the third gear 104 drives the closing door 103 to open. The moving part 6 continues to move, sending the crucible box into the melting machine. After the crucible box enters the melting machine, the clamping part 8 moves a short distance behind the moving part 6.

[0071] The refrigerator 1101 of the cooling table 11 transports the coolant to the cooling box 1002 through the connecting pipe 1006 to cool the crucible box. During the cooling process, the liquid level of the coolant is lower than the height of the crucible box. At the same time, the coolant does not enter the crucible box;

[0072] After the cooling is completed, the first electric push rod 1003 drives the storage plate 1004 to rise, lifting the crucible box to the grasping range of the robotic arm 4;

[0073] The robotic arm 4 starts again to clamp the cooled crucible box, and the robotic arm 4 places the crucible box on the second conveyor 3.

The method for operating the automatic loading and unloading mechanism of a melting machine according to any one of claims 1 to 9, characterized in that: The operation method includes the following steps: Start the melting machine body and the automatic loading and unloading mechanism, put the processed sample into the crucible box and place the crucible box on the first conveyor, and the first conveyor sends the crucible box to the grabbing range of the robot arm; The robot arm moves to the top of the crucible box according to a preset program and clamps the crucible box. The robot arm places the clamped crucible box on the placement plate, and the clamping piece clamps and fixes the crucible box. The control panel controls the moving part to start, and the moving part drives the clamping part to move to the inlet end of the melting machine body and delivers the crucible box into the melting machine. After the delivery is completed, the clamping part moves backward; During the movement, the placement plate is rotated by the transmission member, and the closed door is opened and closed; After the sample processing is completed, the clamping part takes the crucible box out of the fusion machine and returns it to the initial position; The first motor drives the clamping member to rotate 90 degrees and places the crucible box on the storage plate, and the first electric push rod drives the storage plate to descend to cool the crucible box; After cooling is completed, the first electric push rod drives the storage plate to rise, and the robotic arm clamps the cooled crucible box and places it on the second conveyor.
