[0049] Reference Figures 1 to 5 The crucible cleaning device provided by the embodiment of the utility model includes a frame 100, a lifting assembly 200, a limiting assembly 300 and a cleaning assembly 400. The lifting assembly 200 is arranged on the frame 100; the limiting assembly 300 is arranged on the top of the lifting assembly 200, and the limiting assembly 300 is provided with a crucible limiting cylinder 311, and the crucible limiting cylinder 311 is used to fix the crucible cleaning assembly 400 arranged on the frame 100 and located above the lifting assembly 200. The cleaning assembly 400 includes a cleaning seat 420, and the cleaning seat 420 is provided with a cleaning component mounting hole 421 and a flow channel 425, one end of the flow channel 425 is connected to the cleaning component mounting hole 421, and the other end is used to connect the gas transmission device; the first end of the cleaning component mounting hole 421 is sealed with a cleaning component 430, and the second end of the cleaning component mounting hole 421 is provided with an air inlet 423. It should be noted that the lifting assembly 200 is used to adjust the limiting assembly 300 to switch between a first position and a second position. In the first position, the second end of the cleaning component mounting hole 421 is sealed and connected to the crucible limiting cylinder 311; in the second position, the second end of the cleaning component mounting hole 421 is separated from the crucible limiting cylinder 311.

[0050] In the above structure, the embodiment of the utility model can adjust the positional relationship between the cleaning component mounting hole 421 and the crucible limiting tube 311 by setting the lifting assembly 200. When the crucible needs to be cleaned, the cleaning component mounting hole 421 and the crucible limiting tube 311 can be connected in a sealed manner through the lifting assembly 200, so that the cleaning component 430 cleans the crucible 500 fixed on the crucible limiting tube 311. Since the cleaning component mounting hole 421 and the crucible limiting tube 311 are in a sealed connection, a closed space is formed between the two. An air inlet 423 is provided at the second end of the cleaning component mounting hole 421, that is, an air inlet 423 is provided at one end where the cleaning component mounting hole 421 and the crucible limiting tube 311 are released, that is, the air inlet 423 is located at the connection between the cleaning component mounting hole 421 and the crucible limiting tube 311. After the cleaning component 430 removes the residue on the crucible 500, a gas transmission device is connected to the flow channel 425, so that negative pressure is formed inside the cleaning component installation hole 421 and the crucible limiting tube 311, so that gas enters the inside of the crucible, forming an upward vortex to extract the residue, and the automatic cleaning of the residue is completed. The utility model creates a certain negative pressure area inside the cleaning component installation hole 421 and the crucible limiting tube 311, and the suction force generated is relatively large, so that large pieces of residue can be cleaned. After cleaning, the two can be separated by the lifting component 200.

[0051] Specifically, the cleaning component mounting hole 421 is a cylindrical structure, with openings at both ends, and the cleaning component mounting hole 421 can also be understood as a hole that runs through the cleaning seat 420, and the cleaning component mounting hole 421 is arranged perpendicular to the cleaning seat 420. The flow channel 425 is arranged inside the cleaning seat 420, one end of which is connected to the cleaning component mounting hole 421, and the other end extends to the outside of the cleaning seat 420 and is provided with a connecting pipe 422, and the function of the connecting pipe 422 is to facilitate the connection of the flow channel 425 with the gas transmission device. The cleaning component 430 is vertically installed inside the cleaning component mounting hole 421, and the top end extends to the outside through the top opening of the cleaning component mounting hole 421, and the cleaning component 430 is sealed and connected with the top opening of the cleaning component mounting hole 421, so that the gas transmission device can be guaranteed to have only one flow direction when the internal airflow is working, that is, from the air inlet 423 to the connecting pipe 422.

[0052] When the crucible needs to be cleaned, the cleaning component 430 can extend to the inside of the crucible through the bottom opening of the cleaning component mounting hole 421 to clean it. It can be understood that the top of the cleaning component mounting hole 421 is the first end, and the bottom of the cleaning component mounting hole 421 is the second end. In some possible embodiments, the bottom opening of the cleaning component mounting hole 421 is also provided with a sealing member 424. When the cleaning component mounting hole 421 and the crucible limiting cylinder 311 are in contact, the sealing member 424 forms a certain seal between the two to ensure the airtightness inside the flow channel 425.

[0053] The top of the crucible limiting cylinder 311 is open, and the bottom is closed. In some possible embodiments, in order to make the crucible more stably fixed inside the crucible limiting cylinder 311, a limiting groove matching the crucible can be provided inside the crucible limiting cylinder 311, so that the crucible can be stuck inside the limiting groove. A clamping mechanism can also be provided inside the crucible limiting cylinder 311, and when the crucible is prevented from being stuck in the crucible limiting cylinder 311, the clamping mechanism can automatically clamp it.

[0054] Reference Figure 3 In some embodiments of the present invention, the cleaning component 430 includes a housing 431, a motor 432 and a cleaning brush 433. The housing 431 is slidably disposed in the cleaning component mounting hole 421; the motor 432 is disposed in the housing 431, and the output shaft of the motor 432 extends to the outside of the housing 431; the cleaning brush 433 is disposed in the motor 432 for brushing the crucible.

[0055] When the crucible needs to be cleaned, the motor 432 can be started, and the motor 432 drives the cleaning brush 433 to rotate, and the cleaning brush 433 cleans the crucible. It should be noted that the shape and size of the cleaning brush 433 need to match the shape and size of the crucible. In the process of rotation, the cleaning brush 433 can not only clean the dirt on the inner wall of the crucible, but also avoid the wear of the inner wall of the crucible by the cleaning brush 433. It should be noted that in the present embodiment, the connecting rod of the cleaning brush 433 is an electric telescopic rod. When it is necessary to work, the electric telescopic rod is extended so that the brush head of the cleaning brush 433 enters the inside of the crucible. When it is not necessary to work, the electric telescopic rod shrinks. In other possible embodiments, the connecting rod of the cleaning brush 433 can also be a telescopic rod driven by a cylinder.

[0056] Reference Figure 3In some embodiments of the present invention, the cleaning seat 420 is provided with an adjusting component 440, and the adjusting component 440 is used to adjust the height of the cleaning component 430. The adjusting component 440 includes a driving member 441 and a lifting member 442. The driving member 441 is fixedly mounted on the cleaning seat 420, and one end of the lifting member 442 is connected to the driving member 441, and the other end is connected to the cleaning component 430. In this embodiment, the connecting rod of the cleaning brush 433 can be a rod of fixed length.

[0057] When the crucible needs to be cleaned, the lifting member 442 can be driven downward by the driving member 441, and the connecting pipe 422 will drive the entire cleaning member 430 to move downward, so that the cleaning brush 433 is deeply inserted into the crucible. When it is necessary to clean up the large pieces of waste residue, the lifting member 442 can be driven upward by the driving member 441, so that the cleaning brush 433 moves upward, so as to avoid the cleaning brush 433 blocking the discharge of large pieces of waste residue and ensure the smoothness of the flow channel. In addition, the height of the cleaning brush 433 can be adjusted by the adjusting member 440, so that different parts of the crucible can be cleaned.

[0058] Reference Figure 3 ( Figure 3 The arrow in the figure indicates the flow direction of the gas), in some embodiments of the present invention, the port at one end of the flow channel 425 connected to the cleaning component mounting hole 421 is located on the same line as the air inlet 423.

[0059] Specifically, when the gas transmission device starts to suck, a high-speed airflow will be generated on the crucible surface. By using the principle that low pressure will be generated near a high-speed flowing fluid, the air pressure inside the crucible is reduced, forming a pressure difference with the air inlet 423, and the airflow enters the crucible through the air inlet 423, and forms a vortex rising airflow in the crucible, thereby taking away the bottom waste residue, entering the negative pressure channel, and then discharging the waste residue. In this embodiment, since the port at one end of the flow channel 425 connected to the cleaning component mounting hole 421 is located on the same line as the air inlet 423, such a design can form a larger vortex rising airflow inside the crucible due to the pressure difference, so that large pieces of residue can be extracted.

[0060] Reference Figure 6 In some embodiments of the present invention, the cleaning seat 420 is provided with a plurality of cleaning component mounting holes 421, and the limiting assembly 300 is provided with a plurality of crucible limiting cylinders 311, and the cleaning component mounting holes 421 and the crucible limiting cylinders 311 are arranged in a one-to-one correspondence.

[0061] With such a configuration, multiple crucibles can be cleaned at one time, greatly improving the cleaning efficiency. It should be noted that there is no limit on the number of cleaning component mounting holes 421 and crucible limiting tubes 311, and they can be designed according to actual conditions. The cleaning component mounting holes 421 and crucible limiting tubes 311 can also be set to corresponding types according to different crucible types. It should be noted that the types of the three should correspond to each other.

[0062] Reference Figure 6 In some embodiments of the utility model, the limiting assembly 300 includes a crucible limiting plate 310 and a rotating part 320. The crucible limiting plate 310 has at least two crucible placement areas, and the crucible placement areas are symmetrically arranged with respect to the center of the crucible limiting plate 310. The crucible limiting cylinder 311 is located in the crucible placement area. The rotating part 320 is arranged at the top of the lifting assembly 200. The output shaft of the rotating part 320 is connected to the center of the crucible limiting plate 310. The rotating part 320 is used to adjust the position of the crucible placement area so that the cleaning part 430 cleans the crucibles on each crucible placement area in turn. The rotating part 320 can be a stepping motor, a servo motor, or a rotating mechanism formed by a motor and a mechanical transmission structure.

[0063] It is understandable that when there are two crucible placement areas, the two crucible placement areas are symmetrically arranged about the center of the crucible limiting plate 310. When there are three or more crucible placement areas, the crucible placement areas are arranged in a circular array with the vertical center line of the crucible limiting plate 310 as the center. With such a design, when the crucible on one of the crucible placement areas is cleaned, it is only necessary to start the rotating part 320 to make the crucible on the next crucible placement area enter the position to be cleaned. This greatly facilitates the work of the staff and improves the cleaning efficiency of the crucible.

[0064] Figure 7 It is a front view of a lifting assembly and a limiting assembly of a crucible cleaning device provided by the utility model.

[0065] Reference Figure 6 and Figure 7 In some embodiments of the present invention, the lifting assembly 200 includes a base 210, a lifting seat 220 and a lifting component. The base 210 is arranged on the frame 100; the lifting seat 220 is slidably arranged on the base 210, and the limiting assembly 300 is located on the top of the lifting seat 220; the lifting component is arranged between the base 210 and the lifting seat 220 to adjust the height of the lifting seat 220.

[0066] Specifically, the base 210 includes a bottom plate and two side plates, wherein the two side plates are vertically and symmetrically arranged on the top surface of the bottom plate, and a reinforcing rib is arranged between the left and right side plates, and the function of the reinforcing rib is to make the left and right side plates more stable. A slide groove is arranged on the side where the left and right sides are close to each other. Slide blocks are arranged on the left and right sides of the lifting seat 220, and the slide blocks are arranged in a one-to-one correspondence with the slide grooves, and the slide blocks are slidably connected inside the slide grooves. In some other possible embodiments, in order to make the movement of the lifting seat 220 more stable, a protruding block can be arranged on the lifting seat 220, and a guide plate is vertically arranged on the bottom plate of the base 210, and a guide groove is arranged on the guide plate, and the protruding block slides with the guide groove.

[0067] Reference Figure 7 In some embodiments of the utility model, the lifting component includes a lifting plate 230, a telescopic member 250 and an adjusting wheel 260. The lifting plate 230 is arranged at the bottom of the lifting seat 220, and the lifting plate 230 is provided with a recessed area; the telescopic member 250 is horizontally arranged on the base 210, and an adjusting block 240 is provided at the movable end of the telescopic member 250; the adjusting wheel 260 is rotatably arranged on the top of the adjusting block 240, and the adjusting wheel 260 is rollingly connected to the recessed area.

[0068] Specifically, the telescopic member 250 is an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod. The adjustment block 240 is a triangular structure. One side of the adjustment block 240 is arranged parallel to the bottom plate of the base 210, and one corner is located at the highest point, and the adjustment wheel 260 is rotatably arranged on a corner at the highest point of the adjustment block 240. In addition, a groove is provided in the middle of the adjustment wheel 260, and the width of the groove is greater than the thickness of the lifting plate 230, so that the lifting plate 230 is arranged in the groove of the adjustment wheel 260. The recessed area includes two intersecting inclined planes, and the inclination of the inclined plane on the left side is less than the inclination of the inclined plane on the right side, or the inclination of the inclined plane on the right side is less than the inclination of the inclined plane on the left side, or the inclination of the two inclined planes is the same.

[0069] In the above structure, when the height of the lifting seat 220 needs to be increased, the adjusting block 240 can be pushed to move by the telescopic member 250, so that the adjusting wheel 260 on the adjusting block 240 contacts different parts of the lifting plate 230, thereby adjusting the height of the lifting seat 220. Figure 7 As shown, the adjusting wheel 260 contacts the highest point of the recessed area, and the height of the lifting seat 220 is at the lowest. As the adjusting wheel 260 moves leftward or rightward, the height of the lifting seat 220 can be increased.

[0070] Reference Figure 7 In some embodiments of the present invention, the base 210 is provided with a slideway, and the bottom of the adjustment block 240 is provided with a moving wheel, and the moving wheel is connected with the sliding roller. Such a configuration can improve the stability and convenience of the movement of the adjustment block 240.

[0071] Reference Figure 1 In some embodiments of the utility model, the frame 100 includes a support frame 110, which is a rectangular frame structure, with a first placement plate 120 at the bottom and a second placement plate 130 in the middle. The lifting assembly 200 is fixedly mounted on the first placement plate 120, and the cleaning assembly 400 also includes a hanging frame 410, one end of the hanging frame 410 is connected to the second placement plate 130, and the other end is connected to the cleaning seat 420. The cleaning assembly 400 is hung at the bottom of the second placement plate 130 through the hanging frame 410, and is spaced apart from the limit assembly 300.

[0072] In some embodiments of the present invention, a limiting block is provided at the bottom of the cleaning component mounting hole 421, and the limiting block is used to limit the crucible.

[0073] Specifically, there may be a plurality of limit blocks, which are spaced apart along the inner wall of the cleaning component mounting hole 421. One end of the limit block is fixedly connected to the inner wall of the cleaning component mounting hole 421, and the other end extends horizontally toward the center of the cleaning component mounting hole 421, so that the limit block blocks the top of the crucible. With such an arrangement, when the cleaning assembly 400 starts working, the crucible can be prevented from being separated from the crucible limit tube 311 under the action of the airflow, thereby playing a role of blocking and limiting the crucible.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
