Description

Technical Field

[0001] This utility model relates to the field of silicon material feeding equipment, and in particular to a silicon material feeding equipment. Background Technology

[0002] Current crystal pulling processes primarily rely on manual operation in the feeding stage. This involves manually adding bagged silicon material one by one into a quartz drum according to a predetermined formula. This process requires operators with specific expertise to ensure the silicon material meets technical requirements, thus affecting the quality and efficiency of single crystal growth. After feeding, the silicon material in the quartz drum is precisely fed into the single crystal furnace via a lifting device for high-temperature melting and crystallization. However, relying on manual feeding not only suffers from low operational efficiency and high labor intensity but also makes it susceptible to inaccurate formulas due to human error, affecting the stability of the entire production process and product quality. Therefore, there is an urgent need to find a more efficient and safer feeding solution to improve the automation level and production efficiency of the crystal pulling process.

[0003] Existing technologies, such as the utility model patent with publication number CN220827491U, disclose a feeder and monocrystalline silicon production equipment. This patent includes a barrel with openings at both ends and a lifting assembly inserted within the barrel. The lifting assembly is movable relative to the barrel along its length, and the lifting assembly and the inner wall of the barrel together define a space for accommodating raw materials. The feeder also includes a cover that covers one end of the barrel and has a through hole for the lifting assembly to extend from. The outer edge of the cover has a mating part configured to guide and engage with the auxiliary chamber cavity of the monocrystalline furnace. The feeder and monocrystalline silicon production equipment of this utility model offer high safety.

[0004] In daily use, it has been found that when adding materials to quartz, since quartz is generally 2.2 meters high, personnel need to climb to do so. This operation method is quite physically and time-consuming, and climbing is also dangerous and prone to accidents.

[0005] Therefore, it is necessary to provide a new silicon material feeding device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in the existing technology, when adding quartz, since the height of quartz is generally 2.2 meters, personnel need to climb to a height to add the material.

[0017] Preferably, ball bearings are fixedly connected to both sides of the auxiliary block, and the cross-section of the ball bearings is circular.

[0035] The working principle of the silicon material feeding device provided by this utility model is as follows: By setting the adjustment structure 7, the quartz is first placed on the moving plate 709, and at the same time, the limiting plate 710 limits the quartz to prevent it from falling. Then, the servo motor 703 on one side of the positioning plate 702 is started, so that the servo motor 703 drives the first bevel gear 705 to rotate. The first bevel gear 705 drives the second bevel gear 707 to rotate. The second bevel gear 707 drives the screw 706 to rotate inside the auxiliary plate 704. The screw 706 drives the moving plate 709 to move on the positioning rod 708 of the connecting plate 701. When the moving plate 709 moves, the quartz material is fed into the positioning plate 709. After the movement is completed, the electric cylinder 712 is activated, causing the electric cylinder 712 to drive the slider 713 to move within the connecting groove 711. When the slider 713 moves, it also drives the push plate 714 to move, causing the push plate 714 to push the quartz into the adjusting structure 7. The soft pad 715 can prevent the push plate 714 from directly contacting the quartz, preventing damage to the push plate 714. The protective cover 716 can protect the servo motor 703, preventing dust and other debris from entering the servo motor 703. The limit rod 717 can limit the slider 713, preventing the slider 713 from deviating during the movement.

[0036] By setting the auxiliary structure 8, the first electric push rod 802 on the positioning block 801 is first activated, causing the first electric push rod 802 to drive the pull rod 803 to move. The pull rod 803 then drives the conveyor belt 805 to move, causing the conveyor belt 805 to retract on the auxiliary rod 806. When the conveyor belt 805 retracts, the auxiliary rod 806 drives the fixed frame 804 to move, which in turn drives the pulley 811 to move. Simultaneously, one of the fixed frames 804 drives the auxiliary block 807 to move within the slide rail 808. When it reaches the appropriate position, the second electric push rod 809 is activated to move the top block 814, thus... The top block 814 moves the fixed frame 804 to a suitable position. Then, the motor 810 is started and the conveyor belt 805 is used to carry the quartz into the conveying pipe 5 on the platform 4. Then, the vibrator 6 is started to generate transverse and longitudinal waves to stably convey the material in the horizontal direction until it falls into the quartz barrel 3 of the fixed plate 2. The ball bearing 812 can reduce the friction of the auxiliary block 807, thereby making the auxiliary block 807 move more smoothly in the slide rail 808. The clamping plate 813 can fix the pulley 811 to prevent the pulley 811 from rolling.
