Description

Technical Field

[0001] This utility model relates to the field of medium-frequency heated silicon-based materials technology, specifically to a medium-frequency heated silicon-based material blending mechanism. Background Technology

[0002] Medium-frequency heating of silicon-based materials involves heating silicon wafers, ingots, and powders in a medium-frequency heating cabinet. First, the prepared silicon-based material is placed in a suitable position inside the induction coil, specifically in the heating tray inside the cabinet. Then, the heating frequency, power, and time are set. After setting the parameters, the medium-frequency heating equipment is started, allowing the medium-frequency power supply to output alternating current at the set frequency and power, which passes through the induction coil. This generates an alternating magnetic field around the coil. Under the influence of this magnetic field, the silicon-based material begins to generate eddy currents and heat up. During the initial heating phase, close monitoring of the silicon-based material's temperature is crucial. This can be achieved using a temperature monitoring instrument installed on the equipment to measure the material's temperature in real time, ensuring that the temperature rise follows the expected heating curve.

[0003] In current technologies, when heating silicon powder using a medium-frequency heating cabinet, workers need to manually spread the silicon powder evenly on a heating tray before placing the tray into the cabinet. However, this heating method still results in uneven heating, causing the silicon powder in the heating tray to be heated unevenly, thus affecting the heating efficiency. Therefore, a medium-frequency heating silicon-based material blending mechanism is proposed to solve the above problems. Utility Model Content

It solves the problem that when heating silicon powder in a medium-frequency heating cabinet, workers need to manually spread the silicon powder on the heating tray before placing the tray into the cabinet for heating. However, this heating method still results in uneven heating, causing the silicon powder in the heating tray to be heated unevenly, thus affecting the heating efficiency of the silicon powder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medium-frequency heating silicon-based material blending mechanism, comprising a medium-frequency heating cabinet, wherein a material carrying tray is provided inside the medium-frequency heating cabinet, a control panel and a heat dissipation mesh are provided on the medium-frequency heating cabinet, and a material turning structure and a driving structure are provided inside the medium-frequency heating cabinet;

[0006] The material turning structure includes a support frame fixedly installed inside the medium-frequency heating cabinet. A cylindrical annular frame with one end extending through and to the outside is rotatably installed inside the support frame. An installation frame is slidably installed between the left and right side walls of the inner cavity of the cylindrical annular frame. A cleaning component for turning silicon powder is slidably installed inside the installation frame.

[0007] Furthermore, the drive structure includes a mounting box fixedly installed on the left side of the medium-frequency heating cabinet. An asynchronous motor is fixedly installed inside the mounting box, and a transmission component for driving the cylindrical annular frame to rotate is provided on one side of the asynchronous motor.

[0008] Furthermore, the control panel and heat dissipation mesh are both fixedly installed on the medium-frequency heating cabinet, and the material tray is installed inside the medium-frequency heating cabinet.

[0009] Furthermore, a limiting strip is fixedly installed on the rear side wall of the inner cavity of the mounting frame, and a limiting groove is opened on the back of the cleaning component. The inner wall of the limiting groove is slidably connected to the outer surface of the limiting strip.

[0010] Furthermore, the feeding component includes an electric push rod and a connecting block. The electric push rod is fixedly installed on the mounting frame, and the telescopic end of the electric push rod is fixedly connected to the connecting block. The connecting block is fixedly connected to the top of the cleaning component.

[0011] Furthermore, the telescopic component includes a rectangular frame and two linear actuators. The two linear actuators are fixedly mounted on the rectangular frame, which is fixedly mounted on the top of the cylindrical annular frame.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This medium-frequency heated silicon-based material blending mechanism, by incorporating a material-turning structure and a drive structure, utilizes an asynchronous motor as the drive source and mechanical transmission to control the rotation of a cylindrical annular frame. A linear actuator in the telescopic component controls the insertion of a cleaning component into the silicon powder within the material tray. An electric push rod in the feeding component controls the cleaning component's left-right reciprocating movement. The rotating cylindrical annular frame drives the moving cleaning component to rotate, thereby automatically turning the silicon powder in the material tray. This improves the heating efficiency of the silicon powder, resulting in more uniform heating and enhancing the practicality of the medium-frequency heated silicon-based material blending mechanism.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 The medium-frequency heating silicon-based material blending mechanism in this embodiment includes a medium-frequency heating cabinet 1, a material tray 2 inside the medium-frequency heating cabinet 1, a control panel 3 and a heat dissipation mesh plate 4 on the medium-frequency heating cabinet 1, a material turning structure and a driving structure inside the medium-frequency heating cabinet 1, the control panel 3 and the heat dissipation mesh plate 4 are both fixedly installed on the medium-frequency heating cabinet 1, and the material tray 2 is installed inside the medium-frequency heating cabinet 1.

[0021] In this embodiment, the material turning structure includes a support frame 51 fixedly installed inside the medium-frequency heating cabinet 1. A cylindrical annular frame 52 is rotatably installed inside the support frame 51, with one end penetrating and extending to the outside. An installation frame 53 is slidably installed between the left and right side walls of the inner cavity of the cylindrical annular frame 52. A cleaning component 54 for turning silicon powder is slidably installed inside the installation frame 53. A limit strip is fixedly installed on the rear side wall of the inner cavity of the installation frame 53. A limit groove is formed on the back of the cleaning component 54, and the inner wall of the limit groove is slidably connected to the outer surface of the limit strip. To prevent the cleaning component 54 from falling off during left and right movement, a feeding component 55 for controlling the left and right movement of the cleaning component 54 is fixedly installed on the mounting frame 53. The feeding component 55 includes an electric push rod and a connecting block. The electric push rod is fixedly installed on the mounting frame 53, and the telescopic end of the electric push rod is fixedly connected to the connecting block. The connecting block is fixedly connected to the top of the cleaning component 54, so that the cleaning component 54 can be moved left and right by telescopic movement of the electric push rod. A telescopic component 56 for controlling the up and down sliding of the mounting frame 53 is fixedly installed on the cylindrical annular frame 52.

[0022] The telescopic component 56 includes a rectangular frame and two linear actuators. The two linear actuators are fixedly installed on the rectangular frame, which is fixedly installed on the top of the cylindrical annular frame 52. The telescopic ends of the two linear actuators are fixedly connected to the top of the mounting frame 53, so as to control the mounting frame 53 to move downward using the linear actuators, thereby controlling the cleaning component 54 to insert into the silicon powder in the material tray 2.

[0023] By adopting the above technical solution, the two linear actuators in the telescopic component 56 are activated. The linear actuators extend and drive the mounting frame 53 and the cleaning component 54 to move downward until the cleaning component 54 is inserted into the silicon powder in the material tray 2. Then, the electric push rod in the feeding component 55 is activated, which drives the cleaning component 54 to move back and forth inside the mounting frame 53. Then, the drive structure controls the rotation of the cylindrical annular frame 52, so that the rotating cylindrical annular frame 52 drives the moving cleaning component 54 to rotate. Thus, the cleaning component 54 is used to turn over the silicon powder in the material tray 2, thereby improving the heating efficiency and ensuring that the silicon powder is heated evenly.

[0024] In this embodiment, the drive structure includes a mounting box 57 fixedly installed on the left side of the intermediate frequency heating cabinet 1. An asynchronous motor 58 is fixedly installed inside the mounting box 57. A transmission component 59 for driving the cylindrical annular frame 52 to rotate is provided on one side of the asynchronous motor 58. The transmission component 59 includes a bevel gear and a bevel gear ring. The outer surfaces of the bevel gear and the bevel gear ring mesh with each other. The bevel gear ring is fixedly installed on the top of the cylindrical annular frame 52. The output shaft of the asynchronous motor 58 passes through the interior of the intermediate frequency heating cabinet 1 and is rotatably connected to the intermediate frequency heating cabinet 1. The bevel gear is fixedly installed on the outer surface of the output shaft of the asynchronous motor 58, so that the rotating output shaft can drive the cylindrical annular frame 52 to rotate through the meshing of the bevel gear and the bevel gear ring.

[0025] By adopting the above technical solution, the asynchronous motor 58 inside the starting installation box 57 is realized, so that the asynchronous motor 58 drives the output shaft to rotate. The rotating output shaft uses the bevel gear and bevel gear ring in the transmission component 59 to drive the cylindrical annular frame 52 to rotate.

[0026] The working principle of the above embodiments is as follows:

[0027] In use, the medium-frequency heating silicon-based material blending mechanism activates two linear actuators in the telescopic component 56, which extend and move the mounting frame 53 and the cleaning component 54 downwards until the cleaning component 54 inserts into the silicon powder in the material tray 2. Then, the electric push rod in the feeding component 55 is activated, which drives the cleaning component 54 to move back and forth inside the mounting frame 53. The asynchronous motor 58 inside the mounting box 57 is activated, causing the asynchronous motor 58 to drive the output shaft to rotate. The rotating output shaft uses the bevel gear and bevel gear ring in the transmission component 59 to drive the cylindrical annular frame 52 to rotate, which in turn drives the moving cleaning component 54 to rotate. Thus, the cleaning component 54 agitates the silicon powder in the material tray 2, thereby improving heating efficiency and ensuring uniform heating of the silicon powder.
