Description

Technical Field

[0001] This invention belongs to the field of cutting technology, specifically, it relates to a silicon rod fixed-length cutting device. Background Technology

[0002] Silicon single crystal rods formed by zone melting or Czochralski pulling in a furnace are cylindrical single crystal silicon rods. Single crystal silicon wafers are cut from single crystal silicon rods. Generally, the single crystal silicon rods are first cut into square rods to obtain square rods used to prepare single crystal silicon wafers, and then the square rods are sliced ​​to obtain single crystal silicon wafers.

[0003] Patent application number CN201820858606.2 discloses a cutting device for silicon rod production, including a worktable with a working chamber at its bottom and a storage slot at its bottom. The storage slot is located on the worktable and connected to the working chamber. A collection plate is placed in the storage slot, and a collection chamber is located on the collection plate. A working slot is located on the worktable and connected to the working chamber. A silicon rod is placed in the working slot for processing. A pushing device is provided on the worktable to adjust the working height of the adjustment plate, facilitating height adjustment during operation and when not in operation, thus improving the convenience and safety of the operation. An adjustment slot is provided on the adjustment plate, allowing manual pulling of a control lever to slide within the adjustment slot, thereby adjusting the position of the cutting blade in a horizontal position, further facilitating the cutting operation.

[0004] The aforementioned technical solution, by setting a manually pulled control handle, allows the control rod to slide within the adjustment slot, thereby enabling adjustment of the cutting blade position in a horizontal position, facilitating the cutting operation and making cutting easier. However, this patent can only cut one or a small number of silicon rods at a time, and lacks a cutting positioning device. This can easily lead to the silicon rod shaking due to external forces during the cutting process, resulting in inaccurate cutting position and potentially lower cutting efficiency.

[0005] Therefore, in order to solve the above problems, the present invention provides a silicon rod length cutting device. Summary of the Invention

[0006] The purpose of this invention is to provide a silicon rod length-cutting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a silicon rod fixed-length cutting device, comprising a device body, a bottom box installed at the bottom end of the device body, a set of grooves opened at the top end of the bottom box, two sets of collection boxes installed inside the grooves, two sets of first motors installed on each opposite side of the bottom box, a set of first pulleys rotatably installed at the output end of the first motors, two sets of fixing plates installed on each opposite side of the bottom box, a rotating shaft rotatably installed on the fixing plate, two sets of second pulleys and two sets of gears fixedly sleeved on the rotating shaft, the first pulleys and the second pulleys being connected by belt drive, four sets of connecting plates installed at the top end of the bottom box, a set of movable rods slidably installed on the connecting plates, a set of racks installed at one end of the movable rods, the gears meshing with the racks, a set of limiting plates installed at the other end of the movable rods, and a set of mounting plates installed at the top end of the bottom box.

[0008] Furthermore, the two sets of collection boxes are mirror-symmetrical about the mounting plate.

[0009] Furthermore, a set of springs is sleeved on the movable rod, and the springs are installed inside the connecting plate.

[0010] Furthermore, a set of horizontal plates is installed at the top of the mounting plate, and two sets of hydraulic telescopic rods are installed on the horizontal plates. Each set of hydraulic telescopic rods has a set of cutting blades installed at its telescopic end.

[0011] Furthermore, the mounting plate has two sets of mounting slots. A second motor is installed at the top of the inside of the mounting slot. A reciprocating screw is rotatably installed at the bottom of the second motor. A slider is threaded onto the reciprocating screw. A set of rotating plates is rotatably installed on each opposite side of the mounting plate. The rotating plates and the sliders are connected by a connecting rod. A set of positioning slots is provided on the rotating plates.

[0012] Furthermore, the first motor, the hydraulic telescopic rod, and the second motor are electrically connected to an external controller.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this invention, a first motor is provided to drive a limiting plate to move, thereby pushing a silicon rod on a rotating plate to move, so that one end of the rod is fixed to a mounting plate and the other end is fixed to the limiting plate. A rubber layer is installed on one side of both the mounting plate and the limiting plate, which can play a buffering role when the rod is squeezed, and also increase the friction, making the rod clamped and fixed more firmly, thus preventing it from shaking during cutting. Two sets of rotating plates are provided, and multiple sets of silicon rods can be placed on each set of rotating plates, thereby improving the cutting efficiency and making it more convenient to use.

[0015] 2. In this invention, by setting a second motor and a rotating plate, the rotating plate can rotate around the rotating shaft after the cutting is completed, thus tilting it downwards. The cut silicon rod can then slide down the slope and be collected inside the collection box. Therefore, there is no need to send special personnel to collect it, making it more convenient to use.

[0022] The invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0023] Please see Figure 1-3According to an embodiment of the present invention, a silicon rod length-cutting device includes a device body 1. A bottom box 2 is installed at the bottom end of the device body 1. A set of grooves 201 is formed at the top end of the bottom box 2. The grooves 201 can provide a certain space for the rotation of the rotating plate 9. Two sets of collection boxes 202 are installed inside the grooves 201. The grooves 201 are in communication with the front side of the bottom box 2. Therefore, when the silicon rods in the collection box 202 are full, the collection box 202 can be pulled out from its front side. Two sets of collection boxes 202 are installed on each of the opposite sides of the bottom box 2. A first motor 3 is rotatably mounted on the output end of the first motor 3. The first motor 3 drives the first pulley 301 to rotate, which in turn drives the rotating shaft 401 to rotate under the transmission action of the belt 404. This, in turn, drives the gear 403 to rotate. When the gear 403 meshes with the rack 502, it drives the rack 502 to move, thereby pushing the limiting plate 503 to move. This, in turn, pushes one end of the silicon rod to move, so that the other end contacts the mounting plate 6. The clamping and fixing process continues, allowing multiple silicon rods to be clamped and fixed at once, thus increasing cutting efficiency. Two sets of fixing plates 4 are installed on each opposite side of the base box 2. A rotating shaft 401 is rotatably mounted on each fixing plate 4. Two sets of second pulleys 402 and two sets of gears 403 are fixedly sleeved on the rotating shaft 401. The first pulley 301 and the second pulleys 402 are connected by a belt 404. Four sets of connecting plates 5 are installed at the top of the base box 2, and a [missing information - likely a device or mechanism] is slidably mounted on each connecting plate 5. A movable rod 501 is provided, with a rack 502 installed at one end. A gear 403 meshes with the rack 502. A limiting plate 503 is installed at the other end of the movable rod 501. A mounting plate 6 is installed at the top of the base box 2. A rubber layer is installed on one side of both the mounting plate 6 and the limiting plate 503, which can buffer when they are squeezed and increase friction, making them clamped and fixed more firmly and preventing them from shaking when cutting.

[0024] Through the above-described scheme of the present invention, the two sets of collection boxes 202 are mirror-symmetrical about the mounting plate 6. A set of springs 504 are sleeved on the movable rod 501. The springs 504 are installed inside the connecting plate 5. The springs 504 can exert a certain force on the movable rod 501, thus ensuring that the gear 403 can always mesh with the rack 502. A set of horizontal plates 601 is installed at the top of the mounting plate 6. Two sets of hydraulic telescopic rods 7 are installed on the horizontal plates 601. A set of cutting rods is installed at the telescopic end of each set of hydraulic telescopic rods 7. The cutting blade 701 and the hydraulic telescopic rod 7 can push the cutting blade 701 downward to cut the silicon rod. The mounting plate 6 has two sets of mounting slots 8. A second motor 801 is installed at the top of the mounting slot 8. A reciprocating screw 802 is rotatably installed at the bottom of the second motor 801. A slider 803 is threaded onto the reciprocating screw 802. A rotating plate 9 is rotatably installed on each opposite side of the mounting plate 6. The rotating plate 9 and the slider 803 are connected by a connecting rod 804. Next, a set of positioning grooves 901 are provided on the rotating plate 9. The positioning grooves 901 correspond to the positions of the cutting blade 701. The length from the positioning grooves 901 to the mounting plate 6 is constant, thus enabling fixed-length cutting of the silicon rod. When the rotating plate 9 is in a horizontal state, the two sets of rotating plates 9 and the two sets of connecting rods 804 form a mutually balanced triangle. Therefore, when the hydraulic telescopic rod 7 extends and pushes the cutting blade 701 downward, the downward movement of the cutting blade 701 to cut the silicon rod will not cause a large pulling force on the reciprocating lead screw 802, thus avoiding its breakage. Once the cutting is complete, the second motor 801 drives the reciprocating screw 802 to rotate, which in turn drives the slider 803 to move, causing the rotating plate 9 to rotate around the axis of rotation. This allows it to tilt downwards, and the cut silicon rod can slide down the slope and eventually be collected inside the collection box 202. Therefore, it is not necessary to send special personnel to collect it, making it more convenient to use. The first motor 3, the hydraulic telescopic rod 7, and the second motor 801 are electrically connected to an external controller.

[0025] The working principle of the silicon rod fixed-length cutting device of this invention is as follows: In use, the silicon rod to be cut is first placed on the rotating plate 9. Then, the first motor 3 drives the first pulley 301 to rotate. Under the transmission action of the belt 404, the rotating shaft 401 can be rotated, which in turn drives the gear 403 to rotate. When the gear 403 meshes with the rack 502, it can drive the rack 502 to move, thereby pushing the limiting plate 503 to move. Thus, one end of the silicon rod can be moved, so that the other end contacts the mounting plate 6 and is clamped and fixed. Then, the hydraulic telescopic rod 7 extends and pushes the cutting blade 701 to move downward, thereby cutting the silicon rod to a fixed length. After the cutting is completed, the second motor 801 drives the reciprocating screw 802 to rotate, which in turn drives the slider 803 to move, so that the rotating plate 9 rotates around the rotating shaft, thus tilting it downward. The cut silicon rod can slide down the slope and finally be collected inside the collection box 202.

[0026] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
