[0031] Reference Figure 1 , shows one of the axonometric views of a single crystal furnace provided in an embodiment of the present application; refer to Figure 2 , showing the second axonometric view of a single crystal furnace provided in an embodiment of the present application; referring to Figure 3 , showing a cross-sectional view of a single crystal furnace provided in an embodiment of the present application; referring to Figure 4 , shows a schematic diagram of the electrical connection between a controller, a detection component, and a drive component provided in an embodiment of the present application. Figures 1 to 4 As shown, the single crystal furnace includes: a furnace body, a charging cylinder 10 , a connecting rod 20 , an isolation tube 30 and a blocking member 40 .

[0032] The feeding barrel 10 is arranged in the furnace body, and the feeding barrel 10 has a first opening and a second opening relative to each other. The sealing member 40 is arranged at the second opening, and the sealing member 40 blocks the second opening. The isolation tube 30 is located in the feeding barrel 10, at least part of the connecting rod 20 is passed through the isolation tube 30, and the first end of the connecting rod 20 cooperates with the sealing member 40, the connecting rod 20 is connected to the isolation tube 30, the feeding barrel 10 is used to accommodate silicon material, and the isolation tube 30 is used to isolate the silicon material in the feeding barrel 10 from the connecting rod 20; in the case that the silicon material in the feeding barrel 10 is stuck, the connecting rod 20 drives the isolation tube 30 to rotate, so that the silicon material in contact with the isolation tube 30 can move, so that the silicon material in the feeding barrel 10 is unstuck.

[0033] In the embodiment of the present application, since the feeding barrel 10 has a first opening and a second opening relative to each other, the blocking member 40 is disposed at the second opening, and the blocking member 40 blocks the second opening, the inside of the feeding barrel 10 can accommodate silicon material, and silicon material can be added to the inside of the feeding barrel 10 through the first opening. Since the isolation tube 30 is located in the feeding barrel 10, at least part of the connecting rod 20 is passed through the isolation tube 30, and the first end of the connecting rod 20 cooperates with the blocking member 40, and the connecting rod 20 is connected to the isolation tube 30, silicon material can be added to the feeding barrel 10 through the first opening, and the silicon material is located outside the isolation tube 30, and the isolation tube 30 isolates the silicon material from the connecting rod 20 to prevent the connecting rod 20 from contacting the silicon material, and in the process of adding materials, once the material is stuck, the isolation tube 30 can be driven to move by the connecting rod 20, so that the silicon material in contact with the isolation tube 30 will be driven by the isolation tube 30 to move, so that the problem of silicon material stuck in the feeding barrel 10 is solved. That is, in the embodiment of the present application, by connecting the connecting rod 20 with the isolation tube 30, during the process of adding silicon material to the feeding barrel 10, once the silicon material is stuck in the feeding barrel 10, the isolation tube 30 can be driven to move by the connecting rod 20, so that the isolation tube 30 drives the silicon material in contact with it to move, which is equivalent to stirring the silicon material in the feeding barrel 10 through the connecting rod 20 and the isolation tube 30, so that the stuck silicon material moves, and then the stuck silicon material moves more smoothly in the feeding barrel 10. That is, in the embodiment of the present application, the problem of silicon material getting stuck when adding silicon material to the feeding barrel 10 can be solved, so that the efficiency of producing monocrystalline silicon can be improved, and then the production efficiency of solar cells can be improved.

[0034] It should be noted that in the embodiment of the present application, when adding silicon material to the feeding barrel 10, silicon material jamming means that the silicon material is jammed at a certain position of the feeding barrel 10, thereby causing the silicon material to be unable to smoothly fall into the bottom of the feeding barrel 10. In addition, when adding silicon material to the single crystal furnace, crystal pulling can be performed to form silicon rods, and then the silicon rods are sliced ​​to form solar cells. In the embodiment of the present application, the problem of silicon material jamming can be solved, and then the efficiency of producing silicon rods can be improved, thereby improving the production efficiency of solar cells.

[0035] In addition, in the embodiment of the present application, the connecting rod 20 can be formed of a metal material, so that the connecting rod 20 has a higher strength and a longer service life. For example, the connecting rod 20 is formed of stainless steel, and for another example, the connecting rod 20 is formed of an alloy. The isolation tube 30 can be formed of quartz or silicon, so that when the isolation tube 30 contacts the silicon material, the isolation tube 30 can not only isolate the connecting rod 20 from the silicon material, but also the isolation tube 30 can less pollute the silicon material in the feeding cylinder 10.

[0036] In addition, in the embodiment of the present application, once the problem of material jamming occurs in the feeding barrel 10, the connecting rod 20 can rotate, so that the connecting rod 20 drives the isolation tube 30 to rotate, so that the isolation tube 30 drives the silicon material in contact with it to move, and then the position of the silicon material already added to the feeding barrel 10 moves, so that the gap between the silicon materials changes, so that the silicon material is no longer jammed. Among them, the silicon material is usually in block shape, so when the isolation tube 30 rotates, the gap between the silicon material blocks becomes larger, and the friction between the silicon material blocks becomes smaller, so that the silicon material blocks slide more easily, avoiding the silicon material jam.

[0037] In addition, in some embodiments, an elastic member may be provided in the isolation tube 30 , one end of the elastic member abuts against the inner wall of the isolation tube 30 , and the other end of the elastic member is connected to the connecting rod 20 , so that the connecting rod 20 is connected to the isolation tube 30 .

[0038] With such a configuration, the elastic member can connect the connecting rod 20 to the isolation tube 30, so that when the connecting rod 20 rotates, the connecting rod 20 can drive the isolation tube 30 to rotate through the elastic member, thereby moving the silicon material in contact with the isolation tube 30 and releasing the silicon material jam.

[0039] It should be noted that in the embodiment of the present application, the elastic member can be a high temperature resistant elastic member, wherein high temperature refers to a temperature greater than 800 degrees, so as to ensure that the elastic member remains normal in the furnace body of the single crystal furnace, and avoid damage to the elastic member, which affects the connection between the isolation tube 30 and the connecting rod 20. In addition, in actual applications, when it is necessary to connect the connecting rod 20 with the isolation tube 30, the connecting rod 20 can be first inserted into the isolation tube 30, and then the elastic member can be inserted into the gap between the connecting rod 20 and the isolation tube 30. Since the elastic member is deformable, once the elastic member enters the gap between the isolation tube 30 and the connecting rod 20, the elastic member can connect the connecting rod 20 with the isolation tube 30, and in this way, the connection between the connecting rod 20 and the isolation tube 30 can be facilitated.

[0040] Of course, in the embodiment of the present application, the isolation tube 30 and the connecting rod 20 may be connected in other ways, for example, a fixing rod is provided on the outer wall of the connecting rod 20, an opening is provided on the tube wall of the isolation tube 30, and the fixing rod is fixed in the opening on the tube wall of the isolation tube 30, so that the isolation tube 30 is connected to the connecting rod 20. The specific way of connecting the isolation tube 30 and the connecting rod 20 is not limited in the embodiment of the present application.

[0041] It should be noted that, in the embodiment of the present application, the length of the isolation tube 30 may be less than or equal to the length of the feeding cylinder 10 .

[0042] In addition, in some embodiments, the blocking member 40 may be provided with a through hole, the first end of the connecting rod 20 may be provided with a blocking member 21, the connecting rod 20 passes through the through hole, and the blocking member 21 is located on one side of the blocking member 40, and the blocking member 40 is located between the blocking member 21 and the second end of the connecting rod 20, so that the first end of the connecting rod 20 cooperates with the blocking member 40.

[0043] Since the through hole is provided on the plugging member 40, when the connecting rod 20 needs to cooperate with the plugging member 40, the first end of the connecting rod 20 can be passed through the through hole, and the blocking member 21 can be located on one side of the plugging member 40, that is, the plugging member 40 is located between the blocking member 21 and the second end of the connecting rod 20, so that the connecting rod 20 can fix the plugging member 40 through the blocking member 21, so that the plugging member 40 can block the second opening of the feeding barrel 10, ensuring that the silicon material is not easy to leak from the second opening after the silicon material is added to the feeding barrel 10. In addition, after the feeding, when the silicon material in the feeding barrel 10 needs to be removed from the feeding barrel 10, the connecting rod 20 can be moved, so that the connecting rod 20 drives the plugging member 40 to move, and the plugging member 40 releases the blockage of the second opening, and the silicon material can be removed from the second opening.

[0044] It should be noted that in the embodiment of the present application, the shape of the blocking member 40 can be set according to actual needs, for example, the blocking member 40 is cone-shaped, and for another example, the blocking member 40 is disc-shaped. The specific shape of the blocking member 40 is not limited in the embodiment of the present application.

[0045] In addition, in the embodiment of the present application, one end of the isolation tube 30 can be in contact with the sealing member 40, and the other end of the isolation tube 30 can be flush with one end of the feeding barrel 10 where the first opening is set, thereby ensuring that the isolation tube 30 can isolate part of the connecting rod 20 located in the feeding barrel 10 to prevent the silicon material from being contaminated by the connecting rod 20.

[0046] In addition, in some embodiments, the blocking member 21 may be connected to the blocking member 40 so that the blocking member 21 can drive the blocking member 40 to rotate.

[0047] Since the blocking member 21 is connected to the plugging member 40, once the material is stuck in the feeding barrel 10, when the connecting rod 20 rotates, the connecting rod 20 can not only drive the isolation tube 30 to rotate, but also drive the blocking member 21 to rotate, so that the blocking member 21 drives the plugging member 40 to rotate, so that the plugging member 40 and the isolation tube 30 both rotate, thereby applying more force to the silicon material in the feeding barrel 10, which is further conducive to solving the problem of silicon material stuck. That is, by setting the blocking member 21 to be connected to the plugging member 40, it can be further conducive to solving the problem of silicon material stuck.

[0048] It should be noted that the blocking member 21 can be connected to the blocking member 40 by snapping, that is, a snap-fitting boss can be provided on the blocking member 21, and a snap-fitting groove can be provided on the blocking member 40, and the snap-fitting boss is snapped into the snap-fitting groove, so that the blocking member 21 is connected to the blocking member 40. Of course, the blocking member 21 and the blocking member 40 can also be connected in other ways, for example, a through hole is provided on the blocking member 21, and a threaded hole is provided on the blocking member 40, and a bolt passes through the through hole on the blocking member 21 and is embedded in the threaded hole on the blocking member 40, so that the blocking member 21 and the blocking member 40 are connected. The specific way of connecting the blocking member 21 and the blocking member 40 is not limited in the embodiment of the present application.

[0049] Of course, in the embodiment of the present application, the blocking member 21 may also be disconnected from the blocking member 40 .

[0050] In addition, in some embodiments, the single crystal furnace may also include a detection component 100, a controller 200 and a drive component 300. The detection component 100 and the drive component 300 are both electrically connected to the controller 200. The drive component 300 is connected to the connecting rod 20. The drive component 300 is used to drive the connecting rod 20 to rotate. The detection component 100 is used to detect whether the silicon material in the feeding barrel 10 is stuck. When the detection component 100 detects that the silicon material in the feeding barrel 10 is stuck, the controller 200 controls the drive component 300 to operate, so that the drive component 300 drives the connecting rod 20 to rotate, and the connecting rod 20 drives the isolation tube 30 to rotate.

[0051] Since the detection component 100 and the drive component 300 are both electrically connected to the controller 200, and the drive component 300 is connected to the connecting rod 20, once the detection component 100 detects that the silicon material in the feeding barrel 10 is stuck, the detection component 100 can transmit a signal to the controller 200. After the controller 200 receives the signal, the controller 200 can control the drive component 300 to operate, so that the drive component 300 can drive the connecting rod 20 to rotate, and the connecting rod 20 can drive the isolation tube 30 to rotate, and the isolation tube 30 will drive the silicon material in contact with it to move, so that the silicon material is no longer stuck. That is, by setting the detection component 100 and the controller 200, it is possible to achieve a fully automated solution to the problem of silicon material stuck when adding silicon material to the feeding barrel 10, avoid manual participation, and thus reduce the labor intensity of the operator.

[0052] It should be noted that the controller 200 may be a programmable logic controller (PLC). Of course, the controller 200 may also be other types, for example, the controller 200 is a control chip. The specific type of the controller 200 is not limited in the embodiment of the present application.

[0053] In addition, in the embodiment of the present application, the drive component 300 may be a motor. Of course, the drive component 300 may also be other types, for example, the drive component 300 is a steering gear. The embodiment of the present application does not limit the specific type of the drive component 300.

[0054] In addition, in the embodiment of the present application, the detection component 100 may have a detection end, and the detection end faces the first opening of the feeding barrel 10, so that the detection component 100 can detect whether the silicon material in the feeding barrel 10 is stuck in real time.

[0055] In addition, in some embodiments, the detection component 100 may include a shooting module, which faces the first opening of the feeding barrel 10. The shooting module is electrically connected to the controller 200. The shooting module is used to shoot the silicon material in the feeding barrel 10 during the process of feeding into the feeding barrel 10 to determine whether the silicon material in the feeding barrel 10 is stuck; when the shooting module captures that the silicon material in the feeding barrel 10 is stuck, the controller 200 controls the driving component 300 to operate, so that the driving component 300 drives the connecting rod 20 to rotate.

[0056] Since the shooting module faces the first opening of the feeding barrel 10, and the shooting module is electrically connected to the controller 200, during the process of feeding the feeding barrel 10, the shooting module can shoot the silicon material in the feeding barrel 10 in real time, and send the shot image to the controller 200. The shooting module can determine whether the material is stuck in the feeding barrel 10 based on the shot image, or the controller 200 can determine whether the material is stuck in the feeding barrel 10 based on the image sent by the shooting module. Once it is determined that the feeding barrel 10 is stuck, the controller 200 can control the driving assembly 300 to operate, so that the driving assembly 300 drives the connecting rod 20 to rotate, the connecting rod 20 drives the isolation tube 30 to rotate, and the isolation tube 30 drives the silicon material in contact with it to move, thereby solving the problem of silicon material stuck.

[0057] It should be noted that the shooting module can be a CCD camera, so that the CCD camera transmits the captured picture to the controller 200, and the controller 200 can determine whether the material is stuck in the feeding barrel 10 based on the picture captured by the CCD camera. Specifically, the image recognition model can be pre-trained, and the image recognition model is stored in the controller 200, so that the controller 200 determines whether the material is stuck in the feeding barrel 10 according to the image recognition model. Among them, the image recognition model can be an existing model, and the design of this application is only an application of the existing model, and does not involve the improvement of the model.

[0058] Of course, the shooting module may include a shooting component and an identification component. The identification component may be a chip in which an image recognition model is stored. The image of the feeding barrel 10 taken by the shooting component is transmitted to the chip. The chip determines whether there is material stuck in the feeding barrel 10 based on the image recognition model. Once it is determined that there is material stuck in the feeding barrel 10, the chip sends a signal to the controller 200, so that the controller 200 controls the operation of the driving component 300.

[0059] In addition, in some embodiments, the detection component 100 may include a laser sensor, which has a detection end, the detection end facing the first opening of the feeding barrel 10, the laser sensor is electrically connected to the controller 200, and the laser sensor is used to emit a detection laser to the feeding barrel 10 to detect whether the silicon material in the feeding barrel 10 is stuck; when the laser sensor detects that the silicon material in the feeding barrel 10 is stuck, the controller 200 controls the driving component 300 to operate, so that the driving component 300 drives the connecting rod 20 to rotate.

[0060] Since the detection end of the laser sensor is facing the first opening of the feeding barrel 10, and the laser sensor is electrically connected to the controller 200, the laser sensor can detect the silicon material in the feeding barrel 10 in real time during the process of adding material to the feeding barrel 10. Once the laser sensor determines that the material is stuck in the feeding barrel 10, the laser sensor can send a signal to the controller 200, and the controller 200 can control the operation of the driving component 300, so that the driving component 300 drives the connecting rod 20 to rotate, the connecting rod 20 drives the isolation tube 30 to rotate, and the isolation tube 30 drives the silicon material in contact with it to move, thereby solving the problem of silicon material jamming.

[0061] It should be noted that the laser sensor emits a detection light, which is irradiated on the silicon material in the feeding barrel 10. If the feeding barrel 10 is not stuck, the distance between the silicon material in the feeding barrel 10 and the laser sensor detected by the detection light of the laser sensor decreases relatively evenly. If the material is stuck in the feeding barrel 10, the distance between the silicon material in the feeding barrel 10 and the laser sensor detected by the detection light of the laser sensor changes suddenly, so that the laser sensor can determine that there is a problem of material jamming in the feeding barrel 10.

[0062] In addition, in some embodiments, the controller 200 may also be electrically connected to an alarm component 400; when the detection component 100 detects that the silicon material in the feeding barrel 10 is stuck, the controller 200 controls the alarm component 400 to operate so that the alarm component 400 issues an alarm message.

[0063] Since the controller 200 is electrically connected to the alarm component 400, once it is determined that material is stuck in the feeding barrel 10, the controller 200 can control the alarm to run only, so that the alarm component 400 can prompt the operator, so that the operator can pay attention to the situation in the feeding barrel 10, which is convenient for the operator to solve the problem of material jam in the feeding barrel 10.

[0064] It should be noted that the alarm component 400 may be a buzzer. Of course, the alarm component 400 may also be of other types, for example, the alarm component 400 is a flashing light. The specific type of the alarm component 400 is not limited in the embodiment of the present application.

[0065] In addition, in some embodiments, the single crystal furnace may further include a connecting rope 50 and a weight 60; the first end of the connecting rope 50 is connected to the driving assembly 300, the second end of the connecting rope 50 is connected to the weight 60, and the weight 60 is connected to the second end of the connecting rod 20.

[0066] Since the first end of the connecting rope 50 is connected to the driving assembly 300, the second end of the connecting rope 50 is connected to the weight 60, and the weight 60 is connected to the second end of the connecting rod 20, once the driving assembly 300 is running, the driving assembly 300 can drive the weight 60 to rotate through the connecting rope 50, so that the weight 60 drives the connecting rod 20 to rotate, and the connecting rod 20 drives the isolation tube 30 to rotate. That is, by providing the connecting rope 50 and the weight 60, it is convenient to connect the connecting rod 20 with the driving assembly 300, and then it is convenient for the driving assembly 300 to drive the connecting rod 20 to rotate.

[0067] In the embodiment of the present application, since the feeding barrel 10 has a first opening and a second opening relative to each other, the blocking member 40 is disposed at the second opening, and the blocking member 40 blocks the second opening, the inside of the feeding barrel 10 can accommodate silicon material, and silicon material can be added to the inside of the feeding barrel 10 through the first opening. Since the isolation tube 30 is located in the feeding barrel 10, at least part of the connecting rod 20 is passed through the isolation tube 30, and the first end of the connecting rod 20 cooperates with the blocking member 40, and the connecting rod 20 is connected to the isolation tube 30, silicon material can be added to the feeding barrel 10 through the first opening, and the silicon material is located outside the isolation tube 30, and the isolation tube 30 isolates the silicon material from the connecting rod 20 to prevent the connecting rod 20 from contacting the silicon material, and in the process of adding materials, once the material is stuck, the isolation tube 30 can be driven to move by the connecting rod 20, so that the silicon material in contact with the isolation tube 30 will be driven by the isolation tube 30 to move, so that the problem of silicon material stuck in the feeding barrel 10 is solved. That is, in the embodiment of the present application, by connecting the connecting rod 20 with the isolation tube 30, during the process of adding silicon material to the feeding barrel 10, once the silicon material is stuck in the feeding barrel 10, the isolation tube 30 can be driven to move by the connecting rod 20, so that the isolation tube 30 drives the silicon material in contact with it to move, which is equivalent to stirring the silicon material in the feeding barrel 10 through the connecting rod 20 and the isolation tube 30, so that the stuck silicon material moves, and then the stuck silicon material moves more smoothly in the feeding barrel 10. That is, in the embodiment of the present application, the problem of silicon material getting stuck when adding silicon material to the feeding barrel 10 can be solved, so that the efficiency of producing monocrystalline silicon can be improved, and then the production efficiency of solar cells can be improved.
