[0026] A specific embodiment of the present invention provides a crucible cleaning device, including a frame 1, a moving platform 2, a clamping mechanism 3, a purge platform 4 and a brushing platform 5, wherein the moving platform 2 is installed on the frame 1, and the moving platform 2 is equipped with a clamping mechanism 3, the clamping mechanism 3 is used to clamp the crucible, the purge platform 4 and the brushing platform 5 are arranged on the side of the moving platform 2, and the two are arranged in sequence along the moving direction of the moving platform 2, wherein the purge platform 4 is equipped with an air nozzle 19, and the brushing platform 5 is equipped with a brush 27 to achieve purging and brushing of the crucible, and the clamping mechanism 3 can move vertically along the moving platform 2, and align the opening of the clamped crucible with the brush 27 and the air nozzle 19 in sequence.

[0027] During the working process, the crucible to be cleaned is placed on the clamping mechanism 3, the crucible is clamped by the clamping mechanism 3, the crucible is transported to the position of the brushing platform 3, the crucible is brushed by the brush 27, and then the crucible is transported to the position of the purge platform 4, the crucible is purged by the air nozzle 19, and finally the crucible is transported out by the clamping mechanism 3. Automatic cleaning is realized, work efficiency is improved, no manual intervention is required, no harm to people, and the cleaning is clean, which does not affect the next experimental results.

[0028] Specifically, the motion platform 2 is vertically arranged, the clamping mechanism 3 moves in the vertical direction, and the purge platform 4 and the brushing platform 5 are arranged in the vertical direction. The arrangement can also be adjusted according to the situation, such as the motion platform 2 is horizontally arranged, and the clamping mechanism 3 is horizontally arranged.

[0029] Specifically, the purge platform 4 is located above the brushing platform 5. During the cleaning process, it is necessary to brush and then purge, so the crucible needs to be moved downward for brushing and then moved upward for purge. With this arrangement, the crucible can be directly purged after brushing to prevent dust on the brush 27 from contaminating the crucible. If the brushing platform 5 is arranged at the top, the crucible will pass through the brushing platform 5 again during the exit process after purge, causing crucible contamination.

[0030] In the crucible cleaning device provided in the specific embodiment of the present invention, the clamping mechanism 3 includes a clamping jaw 11, a rotating platform 12, a positioning hole 13, a clamping drive mechanism 14 and a fixed seat 15. The rotating platform 12 is installed on the motion platform 2. The rotating platform 12 is an output shaft connected to the fixed seat 15, and the positioning hole 13 is arranged on the fixed seat 15, wherein the positioning hole 13 is a circular step through hole and a waist-shaped countersunk hole, and the two clamping jaws 11 are symmetrically arranged on both sides above the positioning hole 13, and the two clamping jaws 11 are driven by the clamping drive mechanism 14 to reciprocate linear motion. Specifically, a vertical guide rail is arranged on the motion platform 2, and the rotating platform 12 is linearly moved in the vertical direction by a motor-driven chain. The rotating platform 12 can use a rotary motor, and the clamping drive mechanism 14 is a cylinder mechanism, or other types of driving methods are used. Initially, the clamping mechanism 3 is located at the top, and the two jaws 11 are opened. The crucible to be cleaned is moved to the position of the positioning hole 13 and stably placed in the positioning hole 13, and then the two jaws 11 are driven to clamp the crucible, and the rotating platform 12 drives the fixed seat 15 to flip 90 degrees, and then it moves downward under the drive of the moving platform 2, so that the opening of the crucible is aligned with the air nozzle 19 and the brush 27 on the side. After cleaning, it moves upward under the drive of the moving platform 2, and the rotating platform 12 drives the fixed seat 15 to flip 90 degrees to return to its original position, release the jaws 11, and take out the crucible to complete the cleaning.

[0031] The purge platform 4 includes a purge drive mechanism 16, a purge movable seat 17, a mounting plate 18, an air nozzle 19 and a purge fixed seat 20, wherein the purge fixed seat 20 is mounted on the frame 1, the purge drive mechanism 16 is mounted on the purge fixed seat 20, the purge drive mechanism 16 is connected to the purge movable seat 17, and the air nozzle 19 is mounted on the purge movable seat 17 through the mounting plate 18, wherein the purge drive mechanism 16 can adopt a pneumatic drive structure or a motor drive mechanism. During operation, when the crucible moves to the purge platform 4, the purge drive mechanism 16 pushes the air nozzle 19 to move linearly into the crucible opening, starts the air nozzle 19 to purge the crucible, closes the air nozzle 19 after completion, and the purge drive mechanism 16 controls the air nozzle 19 to retract so that the crucible can continue to move.

[0032] The brushing platform 5 includes a brushing driving mechanism 21, a brushing fixed seat 22, a power mechanism 23, a brushing movable seat 24, a coupling 25, a connecting seat 26 and a brush 27. The brushing fixed seat 22 is installed on the frame 1, the brushing driving mechanism 21 is installed on the brushing fixed seat 22, the brushing driving mechanism 21 is connected to the brushing movable seat 24, the brushing movable seat 24 is installed with a connecting seat 26, the brush 27 is installed at the outer end of the connecting seat 26, the power mechanism 23 is installed at the inner end of the connecting seat 26, the power mechanism 23 is connected to the brush 27 through the coupling 25 and drives the brush 27 to rotate, wherein each power mechanism can adopt a pneumatic drive structure or a motor drive mechanism. During the working process, when the crucible moves to the brushing platform 5, the brushing driving mechanism 21 pushes the brush 27 to move straight into the crucible opening, the power mechanism 23 is started to make the brush 27 rotate to brush the crucible, and the brush 27 stops rotating after completion, and the brushing driving mechanism 21 controls the brush 27 to retract so that the crucible can continue to move.

[0033] In order to prevent dust from being raised during the cleaning process, a sealed environment needs to be provided. A surrounding plate 10 is installed around the frame 1, and an upper cover plate 7 is installed on the frame 1 to form a sealed structure. A self-opening door 9 is installed on the upper cover plate 7. The self-opening door 9 can be automatically opened and closed when the crucible is in and out. Furthermore, a fan 8 for blowing air inward is installed on the self-opening door 9.

[0034] On the basis of the crucible cleaning device provided in the above specific embodiments, a waste material collection mechanism 6 is installed under the frame 1, which can collect and clean the falling dust on the basis of improving the sealing structure. Specifically, the waste material collection mechanism 6 includes an inverted cone-shaped collection hopper 28, and a discharge pipe 29 is installed under the collection hopper 28, and the discharge pipe 29 is connected to the negative pressure device.

[0035] The specific implementation process is as follows: the manipulator or the automated device moves the crucible to be cleaned to the self-opening door 9 of the upper cover plate 7, the self-opening door 9 opens, the manipulator places the crucible into the positioning hole 13 of the fixed seat 15 on the clamping mechanism 3, the clamping claw 11 clamps the crucible under the drive of the clamping drive mechanism 14, the manipulator withdraws, and the self-opening door 9 closes. The clamping mechanism 3 moves downward under the drive of the moving platform 2. At the same time, the clamping mechanism 3 rotates 90 degrees. The crucible is brought to the brushing platform 5, and the brush 27 on the brushing platform 5 performs high-speed circular motion under the drive of the power mechanism 23. At the same time, under the drive of the brushing drive mechanism 21, the brush 27 enters the crucible to clean the residue on the inner wall, and then the brush 27 withdraws and stops rotating. The crucible moves upward under the drive of the moving platform 2 and is brought to the purge platform 4. The air nozzle 19 on the purge platform 4 sprays a high-speed airflow, and under the drive of the purge drive mechanism 16, it extends to the front of the crucible to blow away the swept residue. After the purging is completed, the air nozzle 19 is retracted under the drive of the purging drive mechanism 16, and the high-speed gas injection is stopped. The crucible after cleaning is moved upward again under the drive of the moving platform 2, and the clamping mechanism 3 begins to reverse 90 degrees and returns to the position of entering the crucible. At the same time, the self-opening door 9 opens, and the clamping claws 11 on the clamping mechanism 3 release the crucible. The manipulator removes the cleaned crucible, and the self-opening door 9 is closed, and the crucible cleaning is completed. Repeat the above steps to clean all crucibles one by one. At the same time, the residual materials swept away fall into the collecting hopper 28 under the strong blowing of the fan 8 on the self-opening door 9, and are discharged through the discharge hopper 29 under the action of the negative pressure device.
