Description

Technical Field

[0001] This utility model relates to the field of single crystal silicon rod technology, and more specifically, to a purging device. Background Technology

[0002] Currently, in the production process of monocrystalline silicon rods, after the pre-processing steps such as cutting and grinding, residual moisture and silicon powder are easily present on both ends of the monocrystalline silicon rod. The presence of moisture and silicon powder can easily affect the quality of the end face of the monocrystalline silicon rod, thereby affecting subsequent processes such as end face marking, and thus reducing the quality of the product.

[0003] In existing technologies, fixed purging devices are typically used to clean the end faces of monocrystalline silicon rods in order to dry and remove residual moisture and silicon powder from the end faces, thereby improving the quality of the end faces of the monocrystalline silicon rods.

[0004] However, because the angle and position of the fixed purging device are fixed, it can only purify in a single direction and cannot be adjusted according to the different conveying positions of the monocrystalline silicon rod. This results in the inability to purify the end face of the monocrystalline silicon rod from multiple angles, which in turn leads to insufficient purging of the end face of the monocrystalline silicon rod, thereby reducing the quality of the end face of the monocrystalline silicon rod. Utility Model Content

[0005] The main objective of this invention is to provide a purging device to solve the problem that existing devices for purging moisture and silicon powder remaining on the end face of a single crystal silicon rod have poor purging effect on the end face of the single crystal silicon rod.

[0006] To achieve the above objectives, this utility model provides a purging device, comprising: a frame; a drive assembly disposed on the frame, the drive assembly having a rotating shaft, the rotating shaft being oscillating within a predetermined swing angle; a mounting assembly mounted on the rotating shaft; and a purging structure for purging the workpiece to be purged, mounted on the mounting assembly, so that the purging structure oscillates under the drive of the rotating shaft; wherein the mounting assembly is adjustablely mounted on the rotating shaft about its axis, so that the purging angle of the purging structure can be adjusted by adjusting the position of the mounting assembly.

[0007] Furthermore, the drive assembly also includes a drive structure and a connection structure. The connection structure is mounted on the rotating shaft, and the drive structure is driven to connect with the connection structure so as to drive the connection structure to make the rotating shaft swing.

[0008] Furthermore, the drive structure is a cylinder, with one of the cylinder body and piston rod rotatably mounted on the frame, and the other of the cylinder body and piston rod rotatably connected to the connecting structure for driving the connecting structure to rotate the rotating shaft.

[0009] Furthermore, the connecting structure includes a connecting block and a connecting lug. The connecting block is sleeved on the rotating shaft, and the driving structure is rotatably connected to the connecting lug. The purging device also includes: a mounting base, which is mounted on the frame, and the cylinder is rotatably connected to the mounting base; and two connecting seats, which are mounted on the frame and are rotatably connected to both ends of the rotating shaft, respectively.

[0010] Furthermore, the mounting assembly includes: at least two opposing clamping structures, with a clamping space formed between the at least two clamping structures, the size of which is adjustable to clamp or release the rotating shaft; and a connector, one end of which is connected to at least one clamping structure and the other end of which is connected to a purging structure, wherein there are multiple mounting assemblies, which are spaced apart along the length of the rotating shaft.

[0011] Furthermore, each clamping structure has a clamping recess to form a clamping space around it; and / or the mounting assembly also includes a locking structure that passes through the connection between two adjacent clamping structures to lock the two adjacent clamping structures.

[0012] Furthermore, there are two clamping structures. The first end of each clamping structure is rotatably connected by a hinge shaft, and the second end of each clamping structure is connected by a locking structure. The locking structure includes a locking bolt and a locking nut. The locking bolt and the locking nut are threaded together to lock the two clamping structures.

[0013] Furthermore, the purging device also includes: a protective structure, which is arranged around the frame, with at least a portion of the inner wall of the protective structure forming a protective space, and at least a portion of the part to be purged located within the protective space; a conveying structure, which is arranged on the frame, with at least a portion of the conveying structure located within the protective space, and the conveying structure is used to convey the part to be purged; and a collecting structure, which is arranged on the side of the conveying structure away from the part to be purged, the collecting structure having a collecting cavity, the conveying structure having a gap hole, and at least a portion of the collecting cavity communicating with the protective space through the gap hole to collect impurities within the protective space.

[0014] Furthermore, the conveying structure also includes a support leg, and the purging device also includes an air supply structure. The air supply structure is installed on the support leg and is connected to both the purging structure and the drive structure to supply air to the drive structure and the purging structure.

[0015] Furthermore, the purging device also includes: a position sensor, mounted on the frame, for detecting the position of the part to be purged; and a control module, connected to both the position sensor and the drive structure, which controls the operation of the drive structure based on the detection results of the position sensor.

[0016] The present invention utilizes a purging device with a drive assembly mounted on a frame. This drive assembly has a rotating shaft that is oscillating within a predetermined swing angle. A mounting assembly is mounted on the rotating shaft. A purging structure for purging the workpiece is mounted on the mounting assembly, allowing the purging structure to oscillate under the drive of the rotating shaft. The mounting assembly is adjustable around the axis of the rotating shaft, allowing the purging angle of the purging structure to be adjusted by changing the position of the mounting assembly. Thus, during the production process of the workpiece, the drive structure drives the rotating shaft to rotate, thereby rotating the purging structure. This enables the purging structure to perform multi-angle purging of the end face of the workpiece, expanding the purging area, improving the cleanliness of the end face, and enhancing the quality of the end face. This solves the problem of poor purging effect on the end face of monocrystalline silicon rods in existing devices used for purging residual moisture and silicon powder. Meanwhile, the above-mentioned configuration of the mounting components enables the connection between the purging structure and the rotating shaft, allowing the purging structure to be driven by the rotating shaft and thus achieve the oscillation of the purging structure. On the other hand, it allows the operator to adjust the position of the purging structure around the axis of the rotating shaft when adjusting the position of the mounting components around the axis of the rotating shaft, thereby adjusting the purging angle of the purging structure. This makes the purging angle of the purging structure more accurate and appropriate, further improving the cleanliness of the parts to be purged. Attached Figure Description

[0036] To address the problem that existing devices for blowing away residual moisture and silicon powder from the end faces of monocrystalline silicon rods have poor blowing effects, this application provides a blowing device.

[0037] like Figures 1 to 6As shown, the purging device includes a frame 10, a drive assembly 20, and a purging structure 40 for purging the workpiece 1. The drive assembly 20 is mounted on the frame 10 and has a rotating shaft 21, which is oscillating within a predetermined swing angle. A mounting assembly 30 is mounted on the rotating shaft 21. The purging structure 40 for purging the workpiece 1 is mounted on the mounting assembly 30 so that the purging structure 40 oscillates under the drive of the rotating shaft 21. The mounting assembly 30 is adjustablely mounted on the rotating shaft 21 about its axis, so that the purging angle of the purging structure 40 can be adjusted by adjusting the position of the mounting assembly 30.

[0038] Applying the technical solution of this embodiment, the drive assembly 20 of the purging device is mounted on the frame 10. The drive assembly 20 has a rotating shaft 21, which is oscillating within a predetermined swing angle. The mounting assembly 30 is mounted on the rotating shaft 21. The purging structure 40 for purging the part 1 to be purged is mounted on the mounting assembly 30, so that the purging structure 40 swings under the drive of the rotating shaft 21. The mounting assembly 30 is adjustablely mounted on the rotating shaft 21 about its axis, so that the purging angle of the purging structure 40 can be adjusted by adjusting the position of the mounting assembly 30. Thus, during the production process of the part to be purged 1, the drive structure 22 drives the rotating shaft 21 to rotate, thereby realizing the rotation of the purging structure 40. This allows the purging structure 40 to perform multi-angle purging of the end face of the part to be purged 1, expanding the purging area of ​​the purging structure 40, improving the cleanliness of the end face of the part to be purged 1, and enhancing the quality of the end face of the part to be purged 1. This solves the problem that the existing devices used to purge moisture and silicon powder remaining on the end face of the monocrystalline silicon rod have poor purging effect on the end face of the monocrystalline silicon rod. Meanwhile, the above-mentioned configuration of the mounting component 30 enables the connection between the blowing structure 40 and the rotating shaft 21, allowing the blowing structure 40 to be driven by the rotating shaft 21, thereby realizing the swing of the blowing structure 40. On the other hand, when the operator adjusts the position of the mounting component 30 around the axis of the rotating shaft 21, the position of the blowing structure 40 around the axis of the rotating shaft 21 is also adjusted, thereby adjusting the blowing angle of the blowing structure 40. This makes the blowing angle of the blowing structure 40 more accurate and appropriate, further improving the cleanliness of the part 1 to be blown.

[0039] In this embodiment, the component to be purged, 1, is a single-crystal silicon rod.

[0040] In this embodiment, the purging structure 40 is an air knife.

[0041] Specifically, when adjusting the position of the installation component 30 around the axis of the rotating shaft 21, the staff rotates the installation component 30 relative to the rotating shaft 21 to ensure that the blowing angle of the air knife is more appropriate.

[0042] like Figures 1 to 3 As shown, the drive assembly 20 also includes a drive structure 22 and a connecting structure 23. The connecting structure 23 is mounted on the rotating shaft 21, and the drive structure 22 is driven to connect with the connecting structure 23, thereby driving the connecting structure 23 to make the rotating shaft 21 swing. In this way, the drive structure 22 drives the rotating shaft 21 through the connecting structure 23. At the same time, the above-mentioned arrangement of the connecting structure 23 avoids direct connection between the drive structure 22 and the rotating shaft 21, thus preventing vibration caused by the drive structure 22 driving the rotating shaft 21 and resulting in damage to the rotating shaft 21. This not only extends the service life of the rotating shaft 21 but also ensures the operational stability and reliability of the drive assembly 20.

[0043] In this embodiment, the drive structure 22 is controlled by a solenoid valve.

[0044] like Figures 1 to 3 As shown, the drive structure 22 is a cylinder. One of the cylinder body 221 and piston rod 222 is rotatably mounted on the frame 10, and the other is rotatably connected to the connecting structure 23 to drive the connecting structure 23 to rotate the rotating shaft 21. This arrangement converts the linear driving force of the cylinder into torque, thereby realizing the rotation of the rotating shaft 21 and enabling multi-angle blowing by the blowing structure 40. Furthermore, it allows for more flexible and diverse placement of the cylinder body 221 and piston rod 222 to adapt to different working conditions and usage requirements, improving the processing flexibility of the operator. Simultaneously, the cylinder provides a more stable driving force to the rotating shaft 21, ensuring the reliability of the rotation of the rotating shaft 21.

[0045] like Figure 3 As shown, the connecting structure 23 includes a connecting block 231 and a connecting lug 232. The connecting block 231 is sleeved on the rotating shaft 21, and the driving structure 22 is rotatably connected to the connecting lug 232. The purging device also includes a mounting base 50 and a connecting seat 60. The mounting base 50 is mounted on the frame 10, and the cylinder 221 is rotatably connected to the mounting base 50. Two connecting seats 60 are mounted on the frame 10, and each connecting seat 60 is rotatably connected to both ends of the rotating shaft 21. In this way, the connecting structure 23 realizes the connection between the driving structure 22 and the rotating shaft 21 through the connecting block 231, and the connecting structure 23 converts the linear driving force of the driving structure 22 on the rotating shaft 21 into torque through the connecting lug 232, thereby realizing the rotation of the rotating shaft 21. At the same time, the above-mentioned arrangement of the connecting seat 60 realizes the rotational connection between the rotating shaft 21 and the frame 10, and also improves the rotational stability and reliability of the rotating shaft 21.

[0046] In this embodiment, the connecting seat 60 is a mounted bearing.

[0047] In this embodiment, the piston rod 222 is rotatably connected to the connecting lug 232.

[0048] In an embodiment not shown in the accompanying drawings, the cylinder body is rotatably connected to the connecting lug, and the piston rod is rotatably connected to the mounting base.

[0049] like Figures 1 to 3 As shown, the mounting assembly 30 includes at least two opposing clamping structures 31 and a connector 32. A clamping space is formed between the at least two clamping structures 31, the size of which is adjustable to clamp or release the rotating shaft 21. One end of the connector 32 is connected to at least one clamping structure 31, and the other end is connected to the purging structure 40. Multiple mounting assemblies 30 are provided, spaced apart along the length of the rotating shaft 21. This arrangement, on the one hand, achieves connection between the purging structure 40 and the rotating shaft 21, and on the other hand, allows the operator to adjust the position of the mounting assembly 30 around the axis of the rotating shaft 21 while adjusting the clamping space, reducing the difficulty of operation and improving work efficiency. On the other hand, the adjustable clamping space allows the mounting assembly to accommodate rotating shafts 21 of different specifications and sizes, thereby improving the versatility of the mounting assembly 30 and, consequently, the versatility of the purging device. Meanwhile, the arrangement of multiple mounting components 30 improves the stability of the connection between the purging structure 40 and the rotating shaft 21, ensuring the stability and reliability of the oscillation of the purging structure 40.

[0050] In this embodiment, there are two mounting components 30, located on both sides of the connecting structure 23 respectively.

[0051] It should be noted that the number of mounting components 30 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of mounting components 30 may be three, four, five, six, seven, or more.

[0052] like Figure 3 As shown, each clamping structure 31 has a clamping recess 311 to form a clamping space. And / or the mounting assembly 30 also includes a locking structure 33, which passes through the connection point of two adjacent clamping structures 31 to lock the two adjacent clamping structures 31 together. Thus, the above arrangement, on the one hand, increases the contact area between the clamping structure 31 and the rotating shaft 21 through the clamping recess 311, thereby improving the clamping reliability of the clamping structure 31; on the other hand, the locking structure 33 further improves the clamping reliability of the clamping structure 31 on the rotating shaft 21, thereby improving the connection reliability between the purging structure 40 and the rotating shaft 21.

[0053] like Figure 1 and Figure 6 As shown, there are two clamping structures 31. The first end of each clamping structure 31 is rotatably connected via a hinge shaft 34, and the second end of each clamping structure 31 is connected via a locking structure 33. The locking structure 33 includes a locking bolt and a locking nut, with the locking bolt and locking nut threaded together to lock the two clamping structures 31. This arrangement reduces the number of clamping structures 31 while still allowing the mounting assembly 30 to clamp the rotating shaft 21, thus simplifying the structure of the mounting assembly 30, making it easier to manufacture and implement, and reducing the processing difficulty and cost for workers. Simultaneously, the hinge shaft 34 ensures smoother and more convenient clamping of the clamping structures 31, guaranteeing their clamping flexibility. Furthermore, the locking structure 33 simplifies its formation, reduces installation difficulty, and improves worker efficiency.

[0054] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the purging device also includes a protective structure 70, a conveying structure 80, and a collecting structure 90. The protective structure 70 is arranged around the frame 10, and at least a portion of the inner wall of the protective structure 70 forms a protective space 71, within which at least a portion of the part to be purged 1 is located. The conveying structure 80 is arranged on the frame 10, and at least a portion of the conveying structure 80 is located within the protective space 71. The conveying structure 80 is used to convey the part to be purged 1. The collecting structure 90 is located on the side of the conveying structure 80 away from the part to be purged 1. The collecting structure 90 has a collecting cavity, and the conveying structure 80 has a gap hole 81. At least a portion of the collecting cavity communicates with the protective space 71 through the gap hole 81 to collect impurities within the protective space 71. This arrangement ensures that most of the impurities purged by the purging structure 40 are located within the protective space 71 and fall into the collecting cavity through the gap hole 81. This not only improves the cleanliness of the end face of the part to be purged 1 but also ensures the cleanliness of the production environment. Furthermore, it ensures centralized processing of impurities and reduces the workload of personnel. Meanwhile, the above-mentioned arrangement of the conveying structure 80 enables the purging device to simultaneously perform conveying and purging functions, so that the part to be purged 1 is cleaned during the conveying process, further improving processing efficiency.

[0055] In this embodiment, the protective structure 70 is made of acrylic material.

[0056] In this embodiment, the bottom of the frame 10 is connected to two opposite sides of the conveying structure 80. There are four protective structures 70, two of which are connected to the sides of the frame 10 and the conveying structure 80. There is a preset gap between the two protective structures 70 and the conveying structure 80 so that the part to be purged 1 can be conveyed from the preset gap into the protective space 71 and then conveyed out of the protective space 71 to the next station.

[0057] like Figure 1 , Figure 4 and Figure 5 As shown, the conveying structure 80 also includes a support leg 82, and the purging device also includes an air supply structure 100. The air supply structure 100 is mounted on the support leg 82 and is connected to both the purging structure 40 and the drive structure 22 to supply air to them. In this way, the air supply structure 100 ensures the operational reliability of the drive structure 22 and the purging structure 40. Furthermore, mounting the air supply structure 100 on the support leg 82 further saves installation space for the purging device, ensuring its compact structure.

[0058] Specifically, the purging device also includes a position sensor and a control module. The position sensor is mounted on the frame 10 to detect the position of the part 1 to be purged. The control module is connected to both the position sensor and the drive structure 22, and controls the operation of the drive structure 22 based on the detection results from the position sensor. This configuration improves the automation level of the purging device, reduces the labor intensity of workers, and further increases processing efficiency.

[0059] Specifically, when the position sensor detects that the monocrystalline silicon rod is being conveyed to the frame 10, it transmits the detection result to the control module. The control module controls the solenoid valve to connect the air supply structure 100, which drives the piston rod 222 to retract. The rotating shaft 21 rotates and drives the air knife to swing. The air knife blows towards one end face of the monocrystalline silicon rod, and the monocrystalline silicon rod continues to be conveyed. The position sensor continuously detects and transmits the detection result to the control module in real time. The control module controls the solenoid control cylinder piston rod 222 to extend. The rotating shaft 21 rotates and drives the air knife to continue swinging. The blowing angle of the air knife is continuously adjusted from one end face of the monocrystalline silicon rod until it blows towards the other end face of the monocrystalline silicon rod, and the other end face of the monocrystalline silicon rod is swept. The water droplets and silicon powder generated by the sweeping are blown onto the inner wall of the protective structure 70 and collected in the collection chamber of the collection structure 90. Finally, they are recycled and processed by the staff periodically.

[0060] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0061] The drive assembly of the purging device is mounted on the frame. The drive assembly has a rotating shaft that is oscillating within a predetermined swing angle. A mounting assembly is mounted on the rotating shaft. A purging structure for purging the workpiece is mounted on the mounting assembly, allowing the purging structure to oscillate under the drive of the rotating shaft. The mounting assembly is adjustable about the axis of the rotating shaft, allowing the purging angle of the purging structure to be adjusted by changing the position of the mounting assembly. Thus, during the production process of the workpiece, the drive structure drives the rotating shaft to rotate, thereby rotating the purging structure. This enables the purging structure to purify the end face of the workpiece at multiple angles, expanding the purging area, improving the cleanliness of the end face, and enhancing the quality of the end face. This solves the problem of poor purging effect on the end face of monocrystalline silicon rods in existing technologies for purging residual moisture and silicon powder. Meanwhile, the above-mentioned configuration of the mounting components enables the connection between the purging structure and the rotating shaft, allowing the purging structure to be driven by the rotating shaft and thus achieve the oscillation of the purging structure. On the other hand, it allows the operator to adjust the position of the purging structure around the axis of the rotating shaft when adjusting the position of the mounting components around the axis of the rotating shaft, thereby adjusting the purging angle of the purging structure. This makes the purging angle of the purging structure more accurate and appropriate, further improving the cleanliness of the parts to be purged.
