Description

Technical Field

[0001] This application relates to the field of crystal pulling technology, and in particular to crystal stabilizers and crystal pulling equipment. Background Technology

[0002] During the crystal pulling process, when there is insufficient silicon powder, it is necessary to add silicon powder to the crucible through a feeding assembly. Specifically, combined with Figure 1 As shown, the feeding assembly includes a crystal pulling device 1', a connector 2', and a counterweight 3'; the crystal pulling device 1' is connected to the counterweight 3' via the connector 2', and the end of the counterweight 3' facing away from the connector 2' is connected to a tungsten wire rope 4'.

[0003] During the actual feeding process, because the upper end of the weight 3' is connected to the tungsten wire rope 4', when the tungsten wire rope 4' pulls the weight 3' upward, it simultaneously pulls the crystal pulling equipment 1' upward. When the crystal pulling equipment 1' is lifted, the cylinder in the crystal pulling equipment 1' will slowly rotate and rise due to the tungsten wire rope 4'. When the lifting speed is too fast, the cylinder of the crystal pulling equipment 1' will sway from side to side. When the cylinder slowly enters the auxiliary chamber, personnel need to straighten it to reduce the degree of swaying and prevent it from hitting the side wall of the auxiliary chamber due to excessive swaying, thereby preventing the cylinder from breaking.

[0004] However, the above-mentioned manual straightening method is not only dangerous, but also reduces work efficiency.

[0005] Therefore, there is an urgent need for material stabilizers and crystal pulling equipment to solve the technical problems existing in the current technology to a certain extent. Utility Model Content

[0016] The two ends of the elastic part abut against the abutment plate and the fixing ring, respectively.

[0017] In the above technical solution, the width of the abutting plate is greater than the width of the rotating plate, so that the abutting plate protrudes from the rotating plate and forms an abutting edge on the protruding part;

[0018] The two ends of the elastic portion abut against the abutment edge and the fixing ring, respectively.

[0019] In the above technical solution, the rotating plate is coaxial with the abutting plate and forms a preset angle with the axis of the lug;

[0046] Example 1

[0047] This application provides a material stabilizer, disposed on a connector 1 in a feeding assembly; specifically, combined with... Figure 1As shown, the feeding assembly includes a crystal pulling device 1', a connector 2', and a counterweight 3'; the crystal pulling device 1' is connected to the counterweight 3' via the connector 2', and the end of the counterweight 3' facing away from the connector 2' is connected to a tungsten wire rope 4'. The material stabilizer provided in this application is conveniently installed on the connector 1, and the following describes its application in conjunction with... Figures 2-4 This application provides a detailed description of a material stabilizer.

[0048] The stabilizer includes a fixing part 2, an abutting part 3, and an elastic part 4; wherein the combination Figure 3 As shown, the abutting part 3 is rotatably connected to the fixed part 2 via the rotating part 5, that is, the abutting part 3 and the fixed part 2 are rotatably connected. Further, multiple abutting parts 3 are provided, and the multiple abutting parts 3 are arranged at intervals along the circumferential direction of the fixed part 2, so that the multiple abutting parts 3 are claw-shaped; wherein, the elastic part 4 is sleeved on the rotating part 5 and its two ends abut against the fixed part 2 and the abutting part 3 respectively.

[0049] In the actual feeding process (the principle is the same as that in the background art), when the tungsten wire rope 4' pulls the weight 3' upward, it will simultaneously pull the crystal pulling equipment 1' upward. However, when the crystal pulling equipment 1' is lifted, the material cylinder 6 in the crystal pulling equipment 1' will slowly rise due to the slow rotation of the tungsten wire rope 4'. When the lifting speed is too fast, the material cylinder 6 of the crystal pulling equipment 1' will sway from side to side. The material stabilizer of this application can solve the above problems. The actual alignment process is as follows: When the abutting part 3 contacts the contact element (the contact element here refers to the side wall of the auxiliary chamber), the side wall of the auxiliary chamber will apply pressure to the abutting part 3 in the radial direction. This pressure will drive the abutting part 3 to rotate around the rotating part 5. During the rotation of the abutting part 3, since the elastic part 4 abuts against the abutting part 3, the elastic part 4 will be compressed. At this time, the elastic part 4 has a certain elasticity. Since the other end of the elastic part 4 abuts against the fixing part 2 sleeved on the connecting part 1, the connecting part 1 will move in the radial direction. At this time, the alignment of the axis of the fixing part 2 and the connecting part 1 is completed.

[0050] In summary, this application cleverly combines the fixing part 2, the abutting part 3, and the elastic part 4 to achieve automatic alignment of the material cylinder 6. This alignment method replaces the existing manual swinging method, which is safe and efficient.

[0051] In this embodiment, further, combined with Figure 3 See also Figure 4 As shown, the fixing part 2 includes a fixing ring 201, which is sleeved on the connector 1.

[0052] Preferably, in order to prevent the retaining ring 201 from falling off the connector 1, in this embodiment, the retaining ring 201 is configured to be interference-fitted with the connector 1, that is, the retaining ring 201 is securely connected to the connector 1.

[0053] Preferably, in order to prevent the retaining ring 201 from falling off the connector 1, in this embodiment, the retaining ring 201 can also be directly welded to the connector 1.

[0054] Furthermore, the height of the retaining ring 201 is slightly greater than the height of the connector 1, that is, the retaining ring 201 completely encloses the connector 1.

[0055] In this embodiment, further, combined with Figure 3 As shown, the rotating part 5 includes a lug 501 and a connecting shaft 502. There are two lugs 501, which are arranged opposite each other and spaced apart to form a rotation space between them. The connecting shaft 502 is disposed in the rotation space and its two ends are respectively connected to the two lugs 501.

[0056] Specifically, since there are multiple abutting parts 3, there are also multiple rotating parts 5, with each rotating part 5 corresponding to one of the multiple abutting parts 3.

[0057] Furthermore, lug 501 is welded to retaining ring 201.

[0058] In this embodiment, further, combined with Figure 3 As shown, the abutting part 3 includes an abutting plate 301 and a rotating plate 302.

[0059] Specifically, the abutment plate 301 and the rotating plate 302 are sequentially connected along the radial direction of the fixed ring 201. The rotating plate 302 is close to the fixed ring 201 and is rotatably connected to the connecting shaft 502. The abutment plate 301 is far away from the fixed ring 201, and the distance between it and the material cylinder 6 is set between 10 mm and 15 mm.

[0060] Furthermore, the elastic part 4 is sleeved on the connecting shaft 502, and its two ends abut against the abutment plate 301 and the fixing ring 201 respectively.

[0061] When the abutment plate 301 contacts the contact element (here, the contact element refers to the side wall of the auxiliary chamber), the side wall of the auxiliary chamber will exert radial pressure on the abutment plate 301. This pressure will cause the abutment plate 301 to rotate around the connecting shaft 502. During the rotation of the abutment plate 301, since the elastic part 4 is in contact with the abutment plate 301, the elastic part 4 will be compressed. At this time, the elastic part 4 has a certain elasticity. Since the other end of the elastic part 4 is in contact with the fixing ring 201 sleeved on the connecting member 1, the connecting member 1 will move in the radial direction. At this time, the alignment of the axis of the fixing ring 201 and the connecting member 1 is completed.

[0062] More specifically, the width of the abutment plate 301 is greater than the width of the rotating plate 302, so that the abutment plate 301 protrudes from the rotating plate 302, and an abutment edge 303 is formed on the protruding part; the two ends of the elastic part 4 abut against the abutment edge 303 and the fixing ring 201 respectively.

[0063] More specifically, the rotating plate 302 is coaxial with the abutting plate 301 and forms a preset angle with the axis of the lug 501; preferably, the preset angle is 135°. The diameter of the circle formed by the ends of the multiple rotating plates 302 away from the fixing ring 201 is larger than the diameter of the material cylinder 6. That is, during the lifting process, if a shaking problem occurs, the rotating plate 302 will first contact the inner wall of the auxiliary chamber, thereby achieving the alignment of the material cylinder 6.

[0064] More specifically, the abutment plate 301 has a hook portion 304 at one end facing away from the rotating plate 302, and the end face of the hook portion 304 facing away from the rotating plate 302 is parallel to the axis of the fixing portion 2. Furthermore, the hook portion 304 is integrally formed on the abutment plate 301.

[0065] More specifically, there are five abutment parts 3, and the five abutment parts 3 are arranged at intervals along the circumference of the fixing part 2. In this way, it can be ensured that the material cylinder 6 can be aligned in the circumferential direction.

[0066] When the hook part 304 contacts the contact member, the side wall of the auxiliary chamber will apply radial pressure to the hook part 304. This pressure will drive the abutment plate 301 to rotate around the connecting shaft 502. During the rotation of the abutment plate 301, since the elastic part 4 is in contact with the abutment plate 301, the elastic part 4 will be compressed. At this time, the elastic part 4 has a certain elasticity. Since the other end of the elastic part 4 is in contact with the fixing ring 201 sleeved on the connector 1, the connector 1 will move in the radial direction. At this time, the axis of the fixing ring 201 and the connector 1 is aligned, avoiding collision between the material cylinder 6 and the inner side wall of the auxiliary chamber, thereby ensuring the integrity of the material cylinder 6.

[0067] Additionally, it is worth noting that when the hook part 304 contacts the contact member, the side wall of the auxiliary chamber will apply pressure to the hook part 304 in the radial direction. Since the axis of the abutment plate 301 and the lug 501 is at a preset angle, and since the axis of the elastic part 4 is also at a preset angle to the axis of the lug 501, the elastic part 4 will generate a spring force at a preset angle to the axis of the lug 501. This spring force will cause the fixing ring 201 to move upward. Since the fixing ring 201 is fixed to the connector 1, it will cause the connector 1 to move upward, thus assisting in lifting the material cylinder 6 to a certain extent.

[0068] In this embodiment, further, combined with Figure 3As shown, the elastic part 4 includes a spring 401; the spring 401 is sleeved on the connecting shaft 502, and its two ends abut against the abutment edge 303 and the fixing ring 201 respectively.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
