Description

Technical Field

[0001] This utility model relates to the field of polysilicon production technology, and specifically to a polysilicon bundling machine. Background Technology

[0002] In the polysilicon production process, silicon rods (150-200mm in diameter) prepared in the reduction furnace need to be sampled from the central area for quality inspection. Current technology uses a diamond-tipped sampler to take a cylindrical sample with a diameter of 20mm and a length of 150-200mm from approximately 10mm-12mm off-center from the silicon rod. After being drawn into a 6mm diameter silicon core, the overall quality of the silicon rods in the furnace is determined through compositional analysis.

[0003] However, this technology has significant drawbacks: the diamond abrasive cutter head is prone to wear due to high-speed friction, requiring frequent machine shutdowns for replacement; furthermore, the cutter head is susceptible to bending and deformation due to thermal stress during continuous operation, leading to a decrease in machining accuracy. Statistics show that a single sampling takes approximately one hour, and this time can be further increased if cutter head misalignment or abnormal friction caused by foreign objects inside the silicon rod occurs, severely impacting production efficiency.

[0050] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0051] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0052] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0053] Example:

[0054] See Figure 1 This embodiment discloses a polysilicon bundling machine, including a cabinet 100, a cutting head 200, and a fixture 300. One side of the cabinet 100 is a control area 110, which includes a keyboard 111, a display screen 112, and multiple power control keys 113. The other side of the cabinet 100 is a processing area 120, with the cutting head 200 positioned at the top and the fixture 300 positioned at the bottom of the processing area 120, below the cutting head 200.

[0055] Specifically, the cutting head 200 includes an infrared cutting head 210 and a drive assembly 220. The drive assembly 220 is used to drive the infrared cutting head 210 to move and rotate on a horizontal plane. By changing the distance between the infrared cutting head 210 and the axis of rotation through the drive assembly 220, the cutting of samples with different diameters can be controlled. During cutting, the infrared cutting head 210 is turned on, and the drive assembly 220 drives the infrared cutting head 210 to rotate.

[0056] The fixture 300 includes a clamping part 310 and a displacement assembly 320. The clamping part 310 is used to clamp the material (polycrystalline silicon rod), and the displacement assembly 320 is used to drive the clamping part 310 to move on a horizontal plane. After the clamping part 310 clamps the polycrystalline silicon rod, the displacement assembly 320 drives the clamping part 310 to move, thereby realizing the cutting of samples of different shapes.

[0057] Although cylindrical samples are mostly cut in actual production, there are some cases where square samples need to be cut.

[0058] When cutting a circular sample, the clamping part 310 clamps the polycrystalline silicon rod and remains stationary. The infrared cutting head 210 is driven to rotate by the drive assembly 220 to cut the cylindrical sample.

[0059] When cutting a square sample, the drive assembly 220 first adjusts the distance between the infrared cutting head 210 and the axis to be equal to the square root of the sample's side length. Then, after the clamping part 310 clamps the polycrystalline silicon rod, the displacement assembly 320 drives the clamping part 310 and the polycrystalline silicon rod to make two mutually perpendicular linear movements, thereby cutting out the two sides of the sample. Then, the drive assembly 220 drives the infrared cutting head 210 to rotate 180 degrees, and the displacement assembly 320 drives the clamping part 310 and the polycrystalline silicon rod to make two more mutually perpendicular linear movements, cutting out the other two sides of the sample.

[0060] In this embodiment, by replacing the traditional diamond cutting head 200 with an infrared cutting head 210, a non-contact cutting method is used to avoid the problems of easy wear and bending of the cutting head 200.

[0061] In one specific embodiment:

[0062] See Figure 2 and Figure 3 The drive assembly 220 includes a spindle 221, a main motor (not shown in the figure), a support frame 222, and a telescopic unit 223. The spindle 221 is rotatably mounted on the top of the processing area 120. The main motor is also located on the top of the processing area 120, and its output shaft is poweredly connected to the top end of the spindle 221. The spindle 221 is driven to rotate by the main motor.

[0063] The support frame 222 is set on the bottom end of the main shaft 221. The support frame 222 has a slide groove 224, in which the infrared cutting head 210 is slidably arranged. The support frame 222 is also provided with a telescopic unit 223. The telescopic unit 223 drives the infrared cutting head 210 to slide in the slide groove 224, thereby controlling the distance between the infrared cutting head 210 and the axis of the main shaft 221, and thus controlling the side length or diameter of the sample.

[0064] Specifically, the telescopic unit 223 includes a connector 2231, a first screw 2232, and a first motor 2233. The connector 2231 is located on the top of the infrared cutting head 210 and extends through the slide groove 224 from the top. A threaded hole is provided on the connector 2231, which matches the first screw 2232. Both ends of the first screw 2232 are rotatably mounted on the support frame 222. At the same time, the first motor 2233 is also located on the top of the support frame 222, and the output shaft of the first motor 2233 is coaxially connected to one end of the first screw 2232.

[0065] In this embodiment, the first screw 2232 is driven to rotate by the first motor 2233, thereby driving the infrared cutting head 210 to move in the slide groove 224 through the thread matching relationship between the first screw 2232 and the connector 2231. Therefore, in this embodiment, the connector 2231 is the telescopic end of the telescopic unit 223.

[0066] In another specific embodiment:

[0067] See Figure 4 The clamping part 310 includes a base 311, a support plate 312, a movable plate 313, and a linear drive unit 314. The base 311 is mounted on the displacement assembly 320, the support plate 312 is mounted on the base 311, and the movable plate 313 is slidably mounted on the base 311. Both the support plate 312 and the movable plate 313 are vertically oriented, with the movable plate 313 located to one side of the support plate 312. The drive end of the linear drive unit 314 is connected to the movable plate 313 and is used to drive the movable plate 313 closer to or further away from the support plate 312.

[0068] Preferably, two semi-cylindrical pressure bars 315 are respectively provided on the side surfaces of the support plate 312 and the movable plate 313 that are close to each other.

[0069] In this embodiment, the polycrystalline silicon rod is placed between the support plate 312 and the movable plate 313. The movable plate 313 is driven to approach the support plate 312 by the linear drive unit 314, and the polycrystalline silicon rod is clamped by four pressure rods 315. When no cutting is performed, the clamped polycrystalline silicon rod is coaxially distributed with the main shaft 221.

[0070] Specifically, the linear drive unit 314 includes a vertical plate 3141 and a cylinder 3142. The vertical plate 3141 is fixedly mounted on the base 311, and the support plate 312 and the vertical plate 3141 are located on opposite sides of the base 311. The cylinder 3142 is fixedly mounted on the vertical plate 3141, and the piston rod end of the cylinder 3142 is fixedly connected to a movable plate 313, thereby driving the movable plate 313 to move closer to or away from the support plate 312 via the piston rod of the cylinder 3142. Therefore, in this embodiment, the piston rod of the cylinder 3142 is the driving end of the linear drive unit 314.

[0071] In another specific embodiment:

[0072] See Figure 5 The displacement assembly 320 includes a lateral displacement unit 321 and a longitudinal displacement unit 322. Both the lateral displacement unit 321 and the longitudinal displacement unit 322 are located on the top of the processing area 120 and are connected to the clamping part 310, which is generally connected to the base 311.

[0073] The direction of movement of the lateral displacement member driving the clamping part 310 is perpendicular to the direction of movement of the longitudinal displacement unit 322 driving the clamping part 310. Both the lateral displacement member and the longitudinal displacement unit 322 drive the clamping part 310 to move on the horizontal plane.

[0074] Specifically, the lateral displacement unit 321 includes a second motor 3211, a second screw 3212, a lateral slider 3213, and a lateral support rod 3214. The second motor 3211 is fixedly mounted at the bottom of the processing area 120. Both ends of the second screw 3212 are rotatably mounted at the bottom of the processing area 120, and one end of the second screw 3212 is coaxially connected to the second motor 3211. The lateral slider 3213 is slidably mounted on one side of the clamping part 310, typically one side of the base 311, and has a threaded hole that matches the second screw 3212.

[0075] The longitudinal displacement unit 322 includes a third motor 3221, a third screw 3222, a longitudinal slider 3223, and a longitudinal support rod 3224. The third motor 3221 is fixedly mounted at the bottom of the processing area 120. Both ends of the third screw 3222 are rotatably mounted at the bottom of the processing area 120, and one end of the third screw 3222 is coaxially connected to the third motor 3221. The longitudinal slider 3223 is slidably mounted at one end of the clamping part 310, typically one end of the base 311, and has a threaded hole that matches the third screw 3222.

[0076] In this embodiment, the length direction of the second screw 3212 is perpendicular to the length direction of the third screw 3222.

[0077] During operation, the second screw 3212 is driven to rotate by the second motor 3211, thereby driving the clamping part 310 to move along the length of the second screw 3212 on the horizontal plane via the transverse slider 3213. The third screw 3222 is driven to rotate by the third motor 3221, thereby driving the clamping part 310 to move along the length of the third screw 3222 on the horizontal plane via the longitudinal slider 3223.

[0078] Because the clamping part 310 is equipped with a transverse support rod 3214 that matches the transverse slider 3213, and a longitudinal support rod 3224 that matches the longitudinal slider 3223, when the transverse slider 3213 pushes the clamping part 310 to move along the length direction of the second screw 3212, the longitudinal slider 3223 slides on the longitudinal support rod 3224; when the longitudinal slider 3223 pushes the clamping part 310 to move along the length direction of the third screw 3222, the transverse slider 3213 slides on the transverse support rod 3214. This solves the jamming problem that easily occurs when moving in both directions.

[0079] Preferably, a transverse support rod 3214 is provided on each side of the clamping part 310, and a transverse slider 3213 is slidably mounted on each of the two transverse support rods 3214. Both transverse sliders 3213 are matched with the second screw 3212. By providing two transverse support rods 3214 and transverse sliders 3213, the bottom of the clamping part 310 has three support points to ensure the stability of the bottom of the clamping part 310.

[0080] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
