[0002] Quartz crucible pre-charging is a key pre-process in the high-temperature production process of single-crystal silicon and polycrystalline silicon. The core is to accurately calculate the polycrystalline silicon charge amount according to the quartz crucible specifications and process requirements. Taking the production of single-crystal silicon rods as an example, it is necessary to comprehensively consider parameters such as the target silicon rod weight, crucible volume and polycrystalline silicon density to ensure that the raw materials in the melting and crystal pulling process meet the process requirements and avoid production efficiency and product quality problems caused by deviation in charge amount.

[0003] In the pre-loading process, the port of the quartz crucible needs to be sealed after the loading is completed to prevent impurities from mixing in. At present, the commonly used sealing method is to manually buckle a metal sealing suction cup on the port of the quartz crucible, and vacuum the quartz crucible by vacuuming. The vacuum sealing can reduce the oxygen content in the quartz crucible. However, due to the heavy weight of the metal sealing suction cup, the process of manually carrying and buckling the sealing suction cup on the port of the quartz crucible is not only labor-intensive and inconvenient to carry, but also has poor operational stability during the buckling process, and the sealing suction cup is prone to collision with the edge of the quartz crucible, which can easily cause damage to the quartz crucible.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0020] Please see Figure 1 and Figure 2The embodiment of the present invention provides a sealing suction cup auxiliary lifting device for pre-charging a quartz crucible, comprising a lifting mechanism 10, a lifting arm 20, an auxiliary stabilizing mechanism 30 and an auxiliary operating mechanism 40. The lifting arm 20 is arranged in parallel on the lifting mechanism 10, one end of the lifting arm 20 is pin-connected with the lifting mechanism 10, and the other end of the lifting arm 20 is a free end. The free end of the lifting arm 20 can rotate freely and parallelly around the lifting mechanism 10, and a hook 21 for lifting a sealing suction cup 50 is arranged at the free end of the lifting arm 20. The sealing suction cup 50 is a circular metal disc body adapted to the quartz crucible, and a lifting ring 51 is arranged at the center of the upper surface of the sealing suction cup 50. The hook 21 on the lifting arm 20 is adapted to the lifting ring 51. By hooking the lifting ring 51 with the hook 21, the lifting mechanism 10 can drive the lifting arm 20 to lift vertically to lift the sealing suction cup 50, and the auxiliary stabilizing mechanism 30 is symmetrically arranged on both sides of the hook 21, and can be on both sides of the hook 21 The auxiliary control mechanism 40 is arranged at the free end of the lifting arm 20 and is connected with the auxiliary stabilizing mechanism 30 by pulling and pulling the auxiliary control mechanism 40 manually, so as to drive the free end of the lifting arm 20 to rotate freely and parallelly around the lifting mechanism 10, so as to transfer or move the suspended sealing suction cup 50. By rotating the lifting arm 20, the suspended sealing suction cup 50 can be moved to the upper end of the quartz crucible to be sealed. In the process of pushing and pulling the lifting arm 20 to move the sealing suction cup 50, the auxiliary stabilizing mechanism 30 can be manually pulled downward by the auxiliary control mechanism 40, so that the auxiliary stabilizing mechanism 30 is pressed on both sides of the upper surface of the suspended sealing suction cup 50, so that the sealing suction cup 50 remains stable during the movement, and the shaking of the sealing suction cup 50 is reduced, so as to facilitate the manual buckling of the sealing suction cup 50 to the upper end of the quartz crucible, and reduce the occurrence of the sealing suction cup 50 and the edge of the quartz crucible collision.

[0021] Please see Figures 1 to 3The two reset springs 32 are respectively sleeved on the two pressing arms 31, and one end of the two reset springs 32 is respectively against the upper end surface of the lifting arm 20, and the other end thereof is respectively against the connecting plate 33. The lower end surface of the two pressing arms 31 is used to form a supporting force for the pressing arms 31 upwards, and the auxiliary operating mechanism 40 is connected to the connecting plate 33 for traction, and the auxiliary operating mechanism 40 can pull the connecting plate 33 to move downward. When the connecting plate 33 moves downward, the two pressing arms 31 can move downward synchronously along the positioning through holes 22, and at the same time form a downward extrusion force on the two return springs 32, so that the two return springs 32 are compressed and deformed. After the two pressing arms 31 move downward along the positioning through holes 22, the pressing plates 34 arranged at the lower ends of the two pressing arms 31 can be symmetrically pressed on both sides of the upper surface of the suspended sealing suction cup 50, and a downward pressing force is formed on the sealing suction cup 50 by the two pressing plates 34, so that the sealing suction cup 50 can remain stable during the movement. When the auxiliary operating mechanism 40 releases the traction on the connecting plate 33, the two pressing arms 31 can be reset by the rebound force of the two return springs 32, so that the pressing plates 34 at the lower ends of the two pressing arms 31 are away from the sealing suction cup 50.

[0022] Please see Figure 1The auxiliary control mechanism 40 includes an auxiliary operation bracket 41, a handle 42, a traction ring 43, a traction wire 44 and a guide wheel 45. The auxiliary operation bracket 41 is transversely fixedly arranged on one side of the free end of the lifting arm 20. The guide wheel 45 is arranged on the upper end of the lifting arm 20 and is located between the two positioning through holes 22 and facing the middle of the connecting plate 33. The handle 42 is arranged on the side of the auxiliary operation bracket 41 away from the lifting arm 20. The traction ring 43 is movably arranged on the auxiliary operation bracket 41 close to the lifting arm 20. The auxiliary control mechanism 40 further comprises an operating rod 46, which is arranged on the auxiliary operation bracket 41 and is arranged close to one side of the operating handle 42. The traction wire 44 is a wire twisted by multiple strands of thin steel wires. One end of the traction wire 44 is fixedly connected to the traction ring 43. The other end of the traction wire 44 passes through the guide groove of the guide wheel 45 and is fixedly connected to the middle part of the connecting plate 33. The guide wheel 45 plays a role in positioning and guiding the traction wire 44. After the staff member holds the handle 42 with one hand, the finger holding the handle 42 can hook the traction ring 43. When the traction ring 43 is pulled toward the handle 42, the traction wire 44 can be pulled. The auxiliary control mechanism 40 also comprises an operating rod 46, which is arranged on the auxiliary operation bracket 41 and is arranged close to one side of the operating handle 42. This is convenient for the staff member to operate with one hand. The operating rod 46 is an electric control switch, which is electrically connected to the lifting mechanism 10 and is used to control the lifting mechanism 10 to lift.

[0023] During the specific implementation, the staff can hold the handle 42, push and pull the free end of the lifting arm 20 to rotate parallel to the lifting mechanism 10, turn the lifting arm 20 to the top of the sealing suction cup 50, and then control the lifting mechanism 10 to drive the lifting arm 20 to descend through the operating rod 46. After the hook 21 is hung in the ring 51 of the sealing suction cup 50, the lifting mechanism 10 is controlled by the operating rod 46 to drive the lifting arm 20 to rise, and push and pull the lifting arm 20 to turn the lifted sealing suction cup 50 to the front of the quartz crucible to be sealed. When the lifting arm 20 is moved, the worker can hold the handle 42 and hook the traction ring 43 with the fingers holding the handle 42, and pull the traction ring 43 toward the handle 42, and pull the traction wire 44 through the traction ring 43. Under the traction force of the traction wire 44, the connecting plate 33 drives the two pressing arms 31 to move downward, so that the pressing plates 34 at the lower ends of the two pressing arms 31 press on both sides of the upper surface of the suspended sealing suction cup 50, and the sealing suction cup 50 is pressed by the two pressing plates 34. The sealing suction cup 50 forms a downward pressing force, which can limit the inertial swing of the sealing suction cup 50 generated during the movement, reduce the shaking of the sealing suction cup 50, and keep the sealing suction cup 50 stable. At this time, the lifting mechanism 10 is controlled to drive the lifting arm 20 to slowly descend, so that the staff can buckle the sealing suction cup 50 on the upper end of the quartz crucible. During the descent process, the two pressing arms 31 always form a downward pressing force on both sides of the sealing suction cup 50, so that the staff can accurately buckle the sealing suction cup 50 on the port of the quartz crucible. When the sealing suction cup 50 is buckled in place, the staff's fingers release the traction ring 43. After the connecting plate 33 loses the traction force of the traction wire 44, the two pressing arms 31 can be raised and reset under the rebound force of the two reset springs 32, so that the pressure plate 34 at the lower end of the two pressing arms 31 is away from the sealing suction cup 50. At this time, the hook 21 can be taken out from the lifting ring 51 of the sealing suction cup 50 to complete the buckling work of the sealing suction cup 50.

[0024] Furthermore, a magnet 47 is provided on the side of the handle 42 facing the traction ring 43. The traction ring 43 is an iron rectangular ring. When the traction ring 43 is pulled toward the handle 42 and close to the magnet 47, the magnet 47 can generate an attraction for the traction ring 43 to assist in applying force to the traction ring 43, so that the staff can save more effort when pulling the traction ring 43. It should be noted that the attraction of the magnet 47 to the traction ring 43 needs to be smaller than the rebound force of the reset spring 32, so that when the staff releases the traction ring 43, the traction ring 43 can be reset by the traction wire 44 under the rebound force of the reset spring 32.

[0025] Furthermore, the pressure plate 34 at the lower end of the two pressing arms 31 is a laterally arranged arc-shaped plate, which extends laterally to both sides of the lower end of the pressing arm 31 and matches the curvature of the upper surface of the sealing suction cup 50, thereby increasing the contact area and limiting the sealing suction cup 50 from swinging to both sides. In addition, an elastic protective pad is provided on the lower end surface of the pressure plate 34 in contact with the sealing suction cup 50. The elastic protective pad is made of rubber and can increase the friction between the sealing suction cup 50 and the sealing suction cup 50 to keep the sealing suction cup 50 stable.

[0026] Please see Figure 1 and Figure 2 Further, the lifting mechanism 10 includes a base 11, a column 12, a drive motor 13, a screw 14 and a lifting slide 15. The column 12 is vertically arranged at the upper end of the base 11, and a slide rail 16 is vertically arranged on the column 12 along its height direction. The screw 14 is rotatably arranged vertically in the slide rail 16 and is parallel to the slide rail 16. The lifting slide 15 is clamped in the slide rail 16 and is threadedly connected with the screw 14. The drive motor 13 is a servo motor, which is arranged on the column 12 and is connected to the screw 14 axis. The operating rod 24 is electrically connected to the drive motor 13 and is used to control the start of the drive motor 13. The lifting arm 20 is pin-connected to the lifting slide 15 and can rotate freely and parallelly along the lifting slide 15. The drive motor 13 drives the screw 14 to rotate, so as to drive the lifting slide 15 to slide up and down along the slide rail 16, and the lifting arm 20 is driven to rise and fall vertically through the lifting slide 15. In this embodiment, a cylinder or a hydraulic cylinder may be provided on the column 12 to drive the lifting slide 15 to move up and down, so as to lift the lifting arm 20.

[0027] Please see Figure 1 Furthermore, in a preferred embodiment, the lifting arm 20 is composed of a main arm 201 and a secondary arm 202, one end of the main arm 201 is pin-connected to the lifting slide 15, the other end of the main arm 201 extends parallel to the outside of the lifting slide 15, and can rotate freely and parallel to the lifting slide 15, one end of the secondary arm 202 is pin-connected to the end of the main arm 201 away from the lifting slide 15, and can rotate freely and parallel to the main arm 201, the auxiliary stabilizing mechanism 30, the auxiliary control mechanism 40 and the hook 21 are arranged at the end of the secondary arm 202 away from the main arm 201, the main arm 201 and the secondary arm 202 are arranged parallel to each other, and the main arm 201 and the secondary arm 202 are pin-connected to each other, which can improve the mobile operation range and flexibility.

A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
