Description

Technical Field

[0001] The utility model relates to the technical field of silicon core lifting, in particular to a silicon core lifting device. Background Art

[0002] Silicon core lifting is a process for preparing silicon cores. In the semiconductor industry, silicon cores are usually used as starting materials for producing single-crystalline silicon. Silicon core lifting is mainly achieved by the Czochralski method. With the development of society, a large number of silicon core lifting devices have been put into use.

[0003] The prior art such as the utility model with the publication number of CN204342917U discloses a silicon core lifting device, which includes a motor, a rotating wheel, and a guiding component for guiding the lifting direction of the silicon core. The guiding component is fixedly arranged on the wall of the silicon core furnace cylinder. A rotating shaft is fixedly arranged on the end face of the rotating wheel, and the rotating shaft can be connected to the motor. Arc-shaped grooves are arranged on both the circumference of the rotating wheel and the guiding component. The silicon core can be placed in the arc-shaped groove of the guiding component and be in contact with the arc-shaped groove of the rotating wheel. The rotating wheel can rotate around the rotating shaft under the action of the power provided by the motor, and continuously lift the silicon core by means of the friction force between the arc-shaped groove of the rotating wheel and the silicon core. During the silicon core drawing process, the silicon core lifting device itself does not move, avoiding the limitation of the length of a single silicon core lifted by the steel wire rope of the existing silicon core lifting device, and enabling continuous drawing of silicon cores, thereby improving the production efficiency of silicon cores.

[0004] Currently, most silicon core lifting devices use rotating wheels to lift silicon cores. However, during the preparation process of silicon cores, due to the increase in weight, it is difficult for the rotating wheels to push the silicon cores upward, and the silicon cores are prone to slipping, resulting in damage to the silicon cores and increasing the economic losses of producers. Therefore, improvements are needed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that in the prior art, most silicon core lifting devices use rotating wheels to lift silicon cores, but during the preparation process of silicon cores, due to the increase in weight, it is difficult for the rotating wheels to push the silicon cores upward, and the silicon cores are prone to slipping, resulting in damage to the silicon cores and increasing the economic losses of producers. A silicon core lifting device is proposed.

[0006] To achieve the above object, the utility model adopts the following technical scheme: a silicon core lifting device, including a mounting frame and a silicon core body, the silicon core body is located inside the mounting frame, a lifting component is arranged on the upper surface of the mounting frame, the lifting component includes a bracket, the bracket is fixedly connected to the upper surface of the mounting frame, a control motor is installed on the upper surface of the bracket, a mounting hoop is installed on the upper surface of the bracket, the control motor is installed inside the mounting hoop, a winding wheel is fixedly connected to the driving end of the control motor, a pulling rope is fixedly connected to the surface of the winding wheel, one end of the pulling rope is fixedly connected to a carrier frame, a mounting sleeve is fixedly connected to the lower surface of the carrier frame, one end of the silicon core body is inserted into the mounting sleeve, and an auxiliary component is arranged on the surface of the mounting frame. This scheme effectively guides the silicon core to stably rise vertically, and stably lifts the silicon core through the mounting sleeve, reducing the situation of the silicon core slipping off, reducing the probability of silicon core damage, reducing the economic losses of producers, and facilitating the normal use of the equipment.

[0007] Preferably, the inner wall of the mounting sleeve is provided with threads, the upper end of the silicon core body is provided with threads, and the upper end of the silicon core body is screwed into the mounting sleeve.

[0008] Preferably, the number of both the mounting sleeves and the silicon core bodies is five, and the five mounting sleeves and silicon core bodies are arranged at equal intervals.

[0009] Preferably, a guide rod is fixedly connected to the lower surface of the mounting frame, and the carrier frame is slidably connected to the surface of the guide rod. One end of the silicon core body is inserted into the mounting sleeve by means of threaded connection to ensure firm connection. The mounting frame is fixed in a suitable position to provide stable support for the whole device. When it is necessary to lift the silicon core body, the control motor is started, the driving end of the control motor drives the winding wheel to rotate, and the winding wheel starts to wind the pulling rope. As the winding wheel continuously winds the pulling rope, the carrier frame connected to one end of the pulling rope starts to move upward under the pulling force of the pulling rope. Since the lower surface of the carrier frame is connected to the mounting sleeve with the silicon core body installed, the silicon core body is also lifted upward accordingly. During this process, the carrier frame slides along the surface of the guide rod fixed to the lower surface of the mounting frame, and the guide rod plays a guiding role to ensure that the carrier frame rises vertically and prevent it from shifting or shaking during the lifting process. At the same time, the convex block at the lower end of the guide rod can prevent the carrier frame from accidentally slipping off the guide rod.

[0010] Preferably, a convex block is fixedly connected to the lower end of the guide rod, and the cross-section of the convex block is circular.

[0011] Preferably, the auxiliary component includes a support rod fixedly connected to the inner wall of the mounting frame. A sliding rod is slidably connected to the inner wall of the support rod. One end of the sliding rod is fixedly connected to a limiting plate. A spring is sleeved on the sliding rod, and the two ends of the spring are respectively fixedly connected to the surfaces of the support rod and the limiting plate. The end of the sliding rod away from the limiting plate is fixedly connected to a stop block. When the silicon core body is lifted upward, the side surface of the processed silicon rod contacts the limiting plate. Since the longitudinal section of the limiting plate is trapezoidal and two symmetrically arranged guide rollers are rotatably connected to the inner wall, the silicon rod generates rolling friction with the guide rollers during the rising process. On the one hand, the frictional resistance is reduced, and on the other hand, it also plays a certain role in limiting and stabilizing the silicon rod, preventing the silicon rod from swinging greatly during the lifting process. As the silicon rod rises, the limiting plate is subjected to the extrusion force of the silicon rod, pushing the sliding rod to slide into the support rod and compressing the spring. The elastic force of the spring in turn exerts a reverse force on the limiting plate, so that the limiting plate always maintains a certain contact pressure with the silicon rod, further enhancing the stabilizing effect on the silicon rod.

[0012] Preferably, the longitudinal section of the limiting plate is trapezoidal, and two symmetrically arranged guide rollers are rotatably connected to the inner wall of the limiting plate to ensure the normal use of the device.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, one end of the silicon core body is inserted into the mounting sleeve by means of threaded connection to ensure firm connection. The mounting frame is fixed at a suitable position to provide stable support for the entire device. When it is necessary to lift the silicon core body, the motor is controlled to start, and the driving end of the motor drives the winding wheel to rotate. The winding wheel starts to wind the pulling rope. As the winding wheel continuously winds the pulling rope, the carrier frame connected to one end of the pulling rope starts to move upward under the pulling force of the pulling rope. Since the lower surface of the carrier frame is connected to the mounting sleeve equipped with the silicon core body, the silicon core body is also lifted upward accordingly. In this process, the carrier frame slides along the surface of the guide rod fixed on the lower surface of the mounting frame. The guide rod plays a guiding role to ensure that the carrier frame rises vertically and prevent it from deviating or shaking during the lifting process. At the same time, the convex block at the lower end of the guide rod can prevent the carrier frame from accidentally slipping off the guide rod. When the silicon core body is lifted upward, the side surface of the processed silicon rod contacts the limiting plate. Since the longitudinal section of the limiting plate is trapezoidal and two symmetrically arranged guide rollers are rotatably connected to the inner wall, the silicon rod generates rolling friction with the guide rollers during the rising process. On the one hand, the frictional resistance is reduced, and on the other hand, it also plays a certain role in limiting and stabilizing the silicon rod to prevent the silicon rod from swinging greatly during the lifting process. As the silicon rod rises, the limiting plate is subjected to the extrusion force of the silicon rod, pushing the sliding rod to slide into the support rod and compressing the spring. The elastic force of the spring in turn exerts a reverse force on the limiting plate, making the limiting plate always maintain a certain contact pressure with the silicon rod, further enhancing the stabilizing effect on the silicon rod. This solution effectively guides the silicon core to rise stably and vertically, and stably lifts the silicon core through the mounting sleeve, reducing the situation of the silicon core slipping off, reducing the probability of silicon core damage, reducing the economic losses of producers, and facilitating the normal use of the equipment.

[0022] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a silicon core lifting device, including a mounting frame 1 and a silicon core body 2. The silicon core body 2 is located inside the mounting frame 1. A lifting assembly 3 is arranged on the upper surface of the mounting frame 1. The lifting assembly 3 includes a bracket 31, the bracket 31 is fixedly connected to the upper surface of the mounting frame 1. A control motor 32 is installed on the upper surface of the bracket 31. A mounting hoop 33 is installed on the upper surface of the bracket 31. The control motor 32 is installed inside the mounting hoop 33. The driving end of the control motor 32 is fixedly connected to a winding wheel 34. A pulling rope 35 is fixedly connected to the surface of the winding wheel 34. One end of the pulling rope 35 is fixedly connected to a carrier 38. A mounting sleeve 39 is fixedly connected to the lower surface of the carrier 38. One end of the silicon core body 2 is inserted into the mounting sleeve 39. An auxiliary assembly 4 is arranged on the surface of the mounting frame 1. This solution effectively guides the silicon core to move vertically upward stably, and stably lifts the silicon core through the mounting sleeve 39, reducing the situation of the silicon core slipping off, reducing the probability of silicon core damage, reducing the economic losses of producers, and facilitating the normal use of the equipment.

[0023] Specifically, the inner wall of the mounting sleeve 39 is provided with threads, and the upper end of the silicon core body 2 is provided with threads. The upper end of the silicon core body 2 is threadedly inserted into the mounting sleeve 39.

[0024] In this embodiment: the number of both the mounting sleeve 39 and the silicon core body 2 is five, and the five mounting sleeves 39 and the silicon core bodies 2 are arranged at equal intervals.

[0025] Specifically, a guide rod 36 is fixedly connected to the lower surface of the mounting frame 1. The carrier frame 38 is slidably connected to the surface of the guide rod 36. One end of the silicon core body 2 is inserted into the mounting sleeve 39 by means of threaded connection to ensure a firm connection. The mounting frame 1 is fixed at a suitable position to provide stable support for the entire device. When it is necessary to lift the silicon core body 2, the motor 32 is controlled to start, and the driving end of the motor 32 drives the winding wheel 34 to rotate. The winding wheel 34 starts to wind the pulling rope 35. As the winding wheel 34 continuously winds the pulling rope 35, the carrier frame 38 connected to one end of the pulling rope 35 starts to move upward under the pulling force of the pulling rope 35. Since the lower surface of the carrier frame 38 is connected to the mounting sleeve 39 in which the silicon core body 2 is installed, the silicon core body 2 is also lifted upward accordingly. During this process, the carrier frame 38 slides along the surface of the guide rod 36 fixed to the lower surface of the mounting frame 1. The guide rod 36 plays a guiding role to ensure that the carrier frame 38 rises vertically and prevent it from shifting or shaking during the lifting process. At the same time, the convex block 37 at the lower end of the guide rod 36 can prevent the carrier frame 38 from accidentally slipping off the guide rod 36.

[0026] Specifically, a convex block 37 is fixedly connected to the lower end of the guide rod 36, and the cross-section of the convex block 37 is circular.

[0027] In this embodiment: The auxiliary component 4 includes a support rod 41. The support rod 41 is fixedly connected to the inner wall of the mounting frame 1. A sliding rod 42 is slidably connected to the inner wall of the support rod 41. One end of the sliding rod 42 is fixedly connected to a limiting plate 45. A spring 43 is sleeved on the sliding rod 42. The two ends of the spring 43 are respectively fixedly connected to the surfaces of the support rod 41 and the limiting plate 45. A stop block 44 is fixedly connected to the end of the sliding rod 42 away from the limiting plate 45. When the silicon core body 2 is lifted upward, the side surface of the processed silicon rod contacts the limiting plate 45. Since the longitudinal section of the limiting plate 45 is trapezoidal and two symmetrically arranged guide rollers 46 are rotatably connected to the inner wall, the silicon rod generates rolling friction with the guide rollers 46 during the rising process. On the one hand, the frictional resistance is reduced, and on the other hand, it also plays a certain role in limiting and stabilizing the silicon rod to prevent the silicon rod from swinging greatly during the lifting process. As the silicon rod rises, the limiting plate 45 is subjected to the extrusion force of the silicon rod, pushing the sliding rod 42 to slide into the interior of the support rod 41 and compressing the spring 43. The elastic force of the spring 43 in turn exerts a reverse force on the limiting plate 45, so that the limiting plate 45 always maintains a certain contact pressure with the silicon rod, further enhancing the stabilizing effect on the silicon rod.

[0028] Specifically, the longitudinal section of the limiting plate 45 is trapezoidal, and two symmetrically arranged guide rollers 46 are rotatably connected to the inner wall of the limiting plate 45 to ensure the normal use of the equipment.

[0029] Working principle: One end of the silicon core body 2 is inserted into the mounting sleeve 39 by means of threaded connection to ensure firm connection. The mounting frame 1 is fixed in a suitable position to provide stable support for the entire device. When it is necessary to lift the silicon core body 2, the control motor 32 is started, and the driving end of the control motor 32 drives the winding wheel 34 to rotate. The winding wheel 34 starts to wind the pulling rope 35. As the winding wheel 34 continuously winds the pulling rope 35, the carrier 38 connected to one end of the pulling rope 35 starts to move upward under the pulling force of the pulling rope 35. Since the lower surface of the carrier 38 is connected to the mounting sleeve 39 on which the silicon core body 2 is installed, the silicon core body 2 is also lifted upward accordingly. During this process, the carrier 38 slides along the surface of the guide rod 36 fixed on the lower surface of the mounting frame 1. The guide rod 36 plays a guiding role to ensure that the carrier 38 rises vertically and prevent it from shifting or shaking during the lifting process. At the same time, the convex block 37 at the lower end of the guide rod 36 can prevent the carrier 38 from accidentally slipping off the guide rod 36. When the silicon core body 2 is lifted upward, the side surface of the processed silicon rod contacts the limiting plate 45. Since the longitudinal section of the limiting plate 45 is trapezoidal and two symmetrically arranged guide rollers 46 are rotatably connected to the inner wall, the silicon rod generates rolling friction with the guide rollers 46 during the rising process. On the one hand, the frictional resistance is reduced, and on the other hand, it also plays a certain role in limiting and stabilizing the silicon rod to prevent the silicon rod from swinging greatly during the lifting process. As the silicon rod rises, the limiting plate 45 is subjected to the extrusion force of the silicon rod and pushes the sliding rod 42 to slide into the support rod 41, compressing the spring 43. The elastic force of the spring 43 in turn exerts a reverse force on the limiting plate 45, so that the limiting plate 45 always maintains a certain contact pressure with the silicon rod, further enhancing the stabilizing effect on the silicon rod. This solution effectively guides the silicon core to rise vertically and stably, and stably lifts the silicon core through the mounting sleeve 39, reduces the situation of the silicon core slipping off, reduces the probability of silicon core damage, reduces the economic losses of producers, and is convenient for the normal use of the equipment.
