Description

Technical Field

[0001] The utility model relates to the technical field of polysilicon processing, in particular to a polysilicon carbon head material processing device. Background Art

[0002] Graphite chuck is a device used to install silicon core and conduct electricity in polysilicon reduction furnace. It is the core material of polysilicon production in reduction furnace. In the process of polysilicon manufacturing, polysilicon will be attached to graphite chuck. Polysilicon is a necessary raw material for the production of solar photovoltaic panels and thyristor components. The most common and well-known method of producing polysilicon is the improved Siemens method, the principle of which is to reduce high-purity trichlorosilane with high-purity hydrogen, but this reaction needs to be carried out on a high-purity silicon core at about 1100°C. After the reduction reaction is completed, silicon is deposited around the silicon core, and the silicon core and silicon are crushed together as polysilicon raw materials. A large amount of polysilicon material will be attached to the surface of the graphite chuck used, and the staff needs to separate the polysilicon material from the graphite chuck.

[0003] After searching, the polysilicon carbon head material processing device, application number: CN201920409197.2, uses a knocking component to knock on the surface of the graphite chuck below, but in order to make the polysilicon on the surface of the graphite chuck fall off evenly, the staff needs to hold the end of the graphite chuck and rotate the graphite chuck, which causes the flying polysilicon fragments to cause harm to the staff when knocking on the graphite chuck, and the safety is poor. In addition, by holding the graphite chuck, the vibration generated by the knocking component will be transmitted to the hand, which will cause numbness in the palm of the staff after a period of processing work, which will cause trouble for subsequent processing work.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 As shown, a polysilicon carbon head material processing device includes a processing table 1, a groove 2 is opened on the top of the processing table 1, support plates 3 are bolted to the four sides of the top of the processing table 1, a fixing box 4 is arranged above the processing table 1, and the fixing box 4 and the support plate 3 are fixedly connected, a motor 5 is fixed above the back of the fixing box 4, a driving structure 6 is arranged inside the fixing box 4, and a knocking plate 7 is arranged below the fixing box 4, a fixing plate 8 is fixed to the back of the processing table 1, and a rotating structure 9 is movably connected to the front side of the fixing plate 8, and a fixing sleeve 10 is arranged at the rear of the processing table 1.

[0023] The driving structure 6 includes a lifting plate 61, a rotating rod 62, a cam 63, a spring 64 and a push rod 65. The lifting plate 61 is slidably connected to the upper part of the interior of the fixed box 4, the rotating rod 62 is rotatably connected to the upper part of the inner wall of the fixed box 4, and the output shaft of the motor 5 passes through the interior of the fixed box 4 and is fixedly connected to the rear end of the rotating rod 62. The cam 63 is fixed to the front and rear sides of the surface of the rotating rod 62. The spring 64 is fixed to the bottom of the lifting plate 61, and the bottom end of the spring 64 is fixedly connected to the inner wall of the fixed box 4. The push rod 65 is fixed to the left and right sides of the bottom of the lifting plate 61, and the bottom end of the push rod 65 passes through the bottom of the fixed box 4 and is bolted to the top of the knocking plate 7. Guide grooves 11 are provided on both sides of the wall, and guide blocks 12 are fixed on both sides of the lifting plate 61. The guide blocks 12 are located inside the guide grooves 11 and are slidably connected to the inner walls of the guide grooves 11. When the staff turns on the motor 5, the rotating rod 62 rotates, so that the cam 63 pushes the lifting plate 61 below to fall, and the push rod 65 pushes the knocking plate 7 to move, so that the knocking plate 7 contacts the graphite chuck below. Through the rotation of the cam 63 and the continuous rebound of the spring 64, the knocking plate 7 moves back and forth up and down, and the guide blocks 12 on both sides can guide the lifting plate 61, so that the lifting plate 61 can only move in the up and down directions.

[0024] The rotating structure 9 includes a driving wheel 91, a driven wheel 92, a first gear 93 and a second gear 94. The driving wheel 91 is fixed on the surface of the output shaft of the motor 5. The first gear 93 is rotatably connected to the upper side of the front of the fixed plate 8. The driven wheel 92 is rotatably connected to the front side of the first gear 93, and the driving wheel 91 is connected to the driven wheel 92 through a belt. The second gear 94 is rotatably connected to the lower side of the front of the fixed plate 8, and the second gear 94 is meshed with the first gear 93. The diameter of the first gear 93 is smaller than the diameter of the second gear 94, and the rear side of the fixed sleeve 10 is fixedly connected to the front side of the second gear 94. When the staff turns on the motor 5 and the knocking plate 7 moves up and down, the driving wheel 91 can drive the driven wheel 92 below to rotate, and the second gear 94 drives the fixed sleeve 10 on the front side to rotate through the first gear 93 at the rear. Since the diameter of the first gear 93 is smaller than the second gear 94, the second gear 94 rotates slowly, so that the fixed sleeve 10 drives the graphite chuck to rotate so that the polysilicon on its surface falls off.

[0025] The position of the fixing sleeve 10 corresponds to the position of the groove 2. Fixing bolts are provided on both sides of the fixing sleeve 10, and the fixing bolts are threadedly connected to the fixing sleeve 10. When the staff puts the rear end of the graphite chuck into the fixing sleeve 10, the fixing bolts on both sides can be rotated to directly fix the graphite chuck and the fixing sleeve 10, which is convenient for the subsequent fixing sleeve 10 to control the rotation of the graphite chuck.

[0026] Working principle: When the staff needs to separate the polysilicon on the graphite chuck, the staff first takes out the graphite chuck, places the graphite chuck inside the groove 2, pushes the graphite chuck, so that the rear end of the graphite chuck moves to the inside of the fixed sleeve 10, and fixes the rear end of the graphite chuck with the fixing bolts on both sides. After the fixation is completed, the staff can turn on the upper motor 5, so that the push rod 65 pushes the lower knocking plate 7 to move, so that the knocking plate 7 hits the surface of the graphite chuck below. While the knocking plate 7 moves, the rear fixed sleeve 10 also starts to rotate, so that the graphite chuck rotates while being knocked, so that the polysilicon attached to the surface of the graphite chuck can be effectively separated from the graphite chuck. After a period of processing, the staff can remove the graphite chuck to complete the separation operation of the polysilicon.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
