Description

Technical Field

[0001] This application relates to the field of weighing equipment technology, and in particular to an automatic weighing and batching device for the manufacture of quartz crucibles. Background Technology

[0002] Quartz crucibles are high-purity quartz sand products widely used in the photovoltaic and semiconductor fields. They are mainly used for continuous crystal pulling under high-temperature conditions, serving as consumable quartz devices for holding polycrystalline silicon raw materials. They possess properties such as cleanliness, homogeneity, and high-temperature resistance, ensuring the quality of single-crystal silicon rod pulling and making them one of the key auxiliary materials in single-crystal pulling systems.

[0003] The main raw material for quartz crucibles is high-purity quartz sand, typically with a SiO2 content of 99.99% or higher. In some preparation methods, barium carbonate is also used as an auxiliary material. The structure of a quartz crucible is generally divided into an outer layer (opaque layer), a middle layer (vacuum transparent layer), and an inner layer. The outer layer (opaque layer) is a high-density area containing numerous air bubbles, known as the bubble composite layer. It provides uniform heating and good heat preservation. The purity requirements for the outer layer sand are relatively low; for example, it can be prepared using slightly lower quality and stability vein quartz grade A ore, with a purity characteristic of ω(SiO2) ≥ 99.995% (4N5) for a mid-to-high-end product. The middle layer (vacuum transparent layer) is a 3-5mm transparent layer, uniformly dense, and with a smooth surface. It enhances the crucible's strength (resistance to deformation) and reduces the temperature of the inner surface (preventing devitrification), and is known as the bubble-poor layer. The middle layer sand can be prepared using Grade A vein quartz ore as raw material. It is a high-end product with a purity characteristic of ω(SiO2) ≥ 99.998% (4N8), and the total content of 15 impurity elements meets the requirements of IOTA-CG. The inner layer is also a 3-5mm transparent layer with fewer and sparsely distributed bubbles, with diameters ranging from 10 to 100μm. This is called a bubble-poor layer, with a uniform and dense structure to enhance the crucible's strength and reduce the temperature of the inner surface to prevent crystallization. Because the inner layer quartz sand is in direct contact with the molten crystal, extremely high cleanliness is required, with a purity requirement of 4N8 (greater than 99.998%). High requirements are also placed on gas-liquid inclusions, lattice impurities, and stability. Furthermore, different product models and customer requirements result in different types and weights of raw materials.

[0004] The batching process is a critical step in the manufacture of quartz crucibles. Traditionally, this process relies primarily on manual weighing and batching, which is not only time-consuming and labor-intensive but also susceptible to variations in operator skill levels, making it difficult to guarantee consistency and accuracy. Furthermore, manual operation involves multiple contacts with raw materials, posing a risk of contamination. With the development of industrial automation technology, more and more companies are seeking efficient automation solutions to improve production efficiency and product quality.

[0005] In existing technologies, common approaches to address these issues include using single-channel automated weighing equipment, semi-automated weighing systems, and simple mechanical aids. For example, some companies use a single hopper with a synchronously driven quantitative feeder to achieve basic automated weighing; others use multiple fixed weighing platforms combined with manual handling for batch weighing. More advanced solutions utilize pneumatic or electric valves to control material flow, but these methods typically only handle single types of materials and cannot achieve high-precision dynamic weighing.

[0006] Current technologies in this field generally suffer from the following shortcomings: First, the weighing accuracy is not high, especially when multiple materials are mixed, making it difficult to achieve high weighing requirements; second, the degree of automation is limited, still requiring considerable manual intervention and failing to completely free up labor; and third, adaptability is poor, unable to flexibly meet the needs of products with different specifications and models. Therefore, developing a system capable of efficiently and accurately completing the automatic weighing and batching of multiple materials in quartz crucible manufacturing is particularly urgent. Utility Model Content

[0007] To improve the automation and accuracy of material batching in quartz crucible manufacturing, this application provides an automatic weighing and batching device for quartz crucible manufacturing.

[0008] The automatic weighing and batching device for manufacturing quartz crucibles provided in this application adopts the following technical solution:

[0009] An automatic weighing and batching device for quartz crucible manufacturing includes a frame and a controller. At least three sets of parallel weighing and conveying mechanisms are mounted on the frame. Each weighing and conveying mechanism includes a collection bin, a lifting assembly, a weighing assembly, and a conveying assembly mounted on the frame. The collection bin is located on one side of the lifting assembly. The lifting assembly has a dispensing bin on it, and the lifting assembly can lift and lower the dispensing bin, pouring the material from the dispensing bin into the collection bin after the dispensing bin reaches its designated position. A control valve is located at the bottom outlet of the collection bin. A loading bin is located above the weighing assembly and the conveying assembly, below the collection bin. The weighing assembly weighs the loading bin, and the conveying assembly conveys the loading bin laterally. The controller is electrically connected to the lifting assembly, the weighing assembly, the conveying assembly, and the control valve.

[0010] This application sets up multiple weighing and conveying mechanisms, with the coordinated operation of the collection bucket, lifting component, weighing component and transmission component, to accurately and reliably automate the weighing of different product models, different customer requirements and various types of raw materials, realize automatic batching, meet the free combination of different types of raw materials, and precisely control and adjust the measurement range and accuracy of raw material weighing to ensure the accuracy of weighing, thereby meeting the production needs of the product.

[0011] By adopting the above technical solution, the weight of the material in each filling hopper is ensured to meet the preset value, reducing errors during manual weighing and improving the accuracy and consistency of weighing. The automated weighing and batching process replaces traditional manual operation, significantly improving batching speed and work efficiency, and reducing labor costs and labor intensity. The controller can automatically identify the type and batch of raw materials and monitor and adjust the weighing process in real time, ensuring accurate recording and management of batching information and avoiding the possibility of errors in manual recording. The device in this application supports the free combination and precise control of various materials, meeting the needs of different product models and customers, and has high flexibility and applicability.

[0012] Optionally, the collection bins in the multiple sets of weighing and conveying mechanisms are arranged side by side, the lifting components in the multiple sets of weighing and conveying mechanisms are arranged side by side and a partition is provided between two adjacent sets of lifting components, the lifting components are arranged vertically and the collection bins are located at the upper end or near the upper end of the lifting components, and the weighing components and the conveying components are located below the collection bins.

[0013] By adopting the above technical solution, the material collection bins in multiple sets of weighing and conveying mechanisms are arranged side by side, resulting in a compact layout and space-saving design. Simultaneously, the lifting components are arranged side by side with partitions between adjacent sets of lifting components, effectively preventing material mixing and improving the accuracy of batching. The lifting components are vertically positioned, with the material collection bins located at or near their top, facilitating smooth material pouring and accurate metering. The weighing and conveying components are located below the material collection bins, achieving seamless material connection and efficient conveying, further enhancing the automation level and work efficiency of the entire system.

[0014] Optionally, the transmission assembly includes several parallel and spaced transmission belts and a drive motor for driving the belts to rotate; each weighing assembly includes at least two support bars, the support bars are disposed in the gap between two adjacent transmission belts and the support bars can move up and down at two positions on the upper side of the transmission belts, and a weighing pressure sensor is provided on the support bars.

[0015] The support bar can be driven to rise and fall by a cylinder or hydraulic cylinder. When the material collection bucket discharges, the support bar rises and protrudes above the conveyor belt. The material collection bucket is positioned on the support bar, and a weighing pressure sensor on the support bar weighs the bucket. Once the predetermined quantity is reached, a signal is sent to the controller, which closes the control valve to stop the discharge. Then, driven by the cylinder or hydraulic cylinder, the support bar descends and moves to below the upper side of the conveyor belt. The material collection bucket falls onto the conveyor belt, and the drive motor rotates the conveyor belt, thus conveying the bucket forward. By adopting this technical solution, the weighing pressure sensor on the support bar can monitor the weight change of the material collection bucket in real time, ensuring accurate weighing every time; eliminating errors caused by human factors during manual weighing, and improving the reliability and accuracy of weighing. The weighed material can be efficiently transported by the conveyor belt, significantly improving the speed and efficiency of the entire batching process and reducing waiting time and labor costs.

[0016] Optionally, the lifting assembly includes a vertically arranged lifting chain and a lifting plate connected to one side of the lifting chain. The lifting chain is located on one side of the collection bin, and the lifting plate is fixed to the side of the lifting chain away from the collection bin. The dispensing bin is detachably tied to the lifting plate. When the lifting chain drives the dispensing bin to rise to the upper end of the lifting chain, the lifting chain continues to operate and can drive the lifting plate and the dispensing bin to flip towards the side of the collection bin.

[0017] By adopting the above technical solution, the design of the lifting chain and lifting plate enables the distribution hopper to rise smoothly to the designated position and reliably tilt towards the collection hopper to dump materials after reaching the top, ensuring the accuracy and stability of material transfer. The entire process is uniformly scheduled by the controller, ensuring coordination between various actions and further improving the stability and reliability of the system.

[0018] Optionally, as another solution, the lifting assembly includes a vertically arranged lifting chain and a lifting plate connected to one side of the lifting chain. The lifting chain is located on one side of the collection bin, and one side of the lifting plate is hinged to the lifting chain. The dispensing bin is detachably tied to the lifting plate. The frame or the lifting chain is provided with a pusher for pushing the lifting plate and the dispensing bin to flip toward the side of the collection bin.

[0019] By adopting the above technical solution, the material in the dispensing hopper can be automatically flipped and poured into the collection hopper after rising to its designated position, improving the efficiency and accuracy of material transfer. The entire device has a high level of automation, while also ensuring the accuracy and consistency of the weighing and batching processes.

[0020] Optionally, the collecting hopper is a cone-shaped bucket with a flared opening at the top, and a discharge pipe is provided at the lower outlet of the collecting hopper. The control valve is located at the lower outlet of the collecting hopper or on the discharge pipe.

[0021] By adopting the above technical solution, the collecting hopper is designed in a conical shape with a flared opening at the top, which effectively increases the inlet area, facilitating smooth material entry into the collecting hopper and reducing blockages. A discharge pipe is installed at the lower outlet, and a control valve is installed at the discharge pipe or the bottom outlet of the collecting hopper, making the material flow more controllable, avoiding leakage or unstable flow caused by improper valve position, and improving weighing accuracy and stability.

[0022] Optionally, the controller is a PLC controller or a microcontroller controller. The frame is also equipped with a display screen for displaying operating parameters. The controller is electrically connected to the display screen, and the display screen is also equipped with an alarm light and an emergency button.

[0023] By adopting the above technical solutions, the actions of each component can be precisely controlled, ensuring the accuracy of weighing and conveying, and improving the automation level of the device.

[0024] Optionally, the dispensing bin is provided with an identification code, and the frame is provided with a code reader for reading the information on the identification code, the code reader being electrically connected to the controller.

[0025] By adopting the above technical solution, the function of automatically identifying raw material types and batches is realized. By transmitting the ingredient information to the control system, the control system can automatically control weighing and conveying according to needs. This reduces errors from manual recording and improves the accuracy and consistency of ingredient preparation, thereby greatly improving the efficiency and reliability of the entire ingredient preparation process.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0043] The following will be combined with the appendix Figure 1 - Appendix Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.

[0044] Example 1

[0045] The automatic weighing and batching device in this application is used in the manufacturing process of quartz crucibles. It accurately and reliably weighs various required raw materials automatically according to process requirements, different product models, and different customer requirements, and achieves automatic batching. (Refer to...) Figure 1and Figure 2 As shown, the automatic weighing and batching device in this application includes a frame 10 and a controller 20. At least three sets of weighing and conveying mechanisms 30 are arranged side by side on the frame 10. In this embodiment, three sets of weighing and conveying mechanisms 30 are used as an example, which can respectively correspond to the outer layer material, middle layer material, and inner layer material of the quartz crucible. Each weighing and conveying mechanism 30 includes a collection bin 31, a lifting assembly 32, a weighing assembly 33, and a transmission assembly 34 mounted on the frame 10. The collection bin 31 is located on one side of the lifting assembly 32, which is equipped with a distributing bin 40. Multiple distributing bins 40 are used to hold different materials. The lifting assembly 32 can lift and lower the distributing bins 40, and after the distributing bins 40 reach their designated positions, the material inside is poured into the collection bin 31. A control valve 35 is installed at the bottom outlet of the collection bin 31. A loading bin 50 is located above the weighing assembly 33 and the transmission assembly 34, below the collection bin 31. A control valve 35 is installed at the bottom of the collection bin 31. After valve 35 is opened, the material in the collection bin 31 falls into the corresponding loading bin 50 below. The weighing component 33 weighs the loading bin 50. After the weighing component 33 feeds back the weighing data to the controller 20, the weight of the material in the loading bin 50 can be calculated. Based on the comparison with the predetermined value, the control valve 35 is opened or closed, so that the weight of the material in the loading bin 50 meets the preset requirements. Then, the transmission component 34 horizontally conveys the loading bin 50 and the material in the loading bin 50. The controller 20 is electrically connected to the lifting component 32, the weighing component 33, the transmission component 34, and the control valve 35 to realize the automated control of the entire device. In this application, the collection bins 31 in the multiple sets of weighing and conveying mechanisms 30 are arranged side by side, with a compact overall layout that saves space. The lifting components 32 in the multiple weighing and conveying mechanisms 30 are arranged side by side and a partition 11 is provided between two adjacent lifting components 32 to effectively prevent the materials in each weighing and conveying mechanism 30 from mixing. The lifting components 32 are arranged vertically and the collection bucket 31 is located at the upper end or near the upper end of the lifting components 32. The weighing components 33 and the transmission components 34 are located below the collection bucket 31.

[0046] Furthermore, refer to Figure 1As shown, the transmission assembly 34 includes several parallel and spaced transmission belts 341 and a drive motor 342 for driving the belts. Each weighing assembly 33 includes at least two support bars 331, which are positioned in the gap between adjacent transmission belts 341 and can move up and down to two positions on the upper side of the transmission belts 341. A weighing pressure sensor 332 is installed on the support bar 331. The support bar 331 can be driven to rise and fall by a cylinder or hydraulic cylinder. When the collection bucket 31 discharges material, the support bar 331 rises and protrudes from the upper side of the transmission belts 341, and the loading bucket 50 is located on the support bar 331. The weighing pressure sensor 332 on the support bar 331 weighs the loading bucket 50. After reaching a predetermined quantity, a signal is promptly sent to the controller 20, which closes the control valve 35 to stop the discharge from the collection bucket 31. Then, driven by a cylinder or hydraulic cylinder, the support bar 331 descends and moves to the underside of the upper side of the conveyor belt 341. The filling bucket 50 falls onto the conveyor belt 341, and the drive motor 342 drives the conveyor belt 341 to rotate, thereby conveying the filling bucket 50 forward. The weighing pressure sensor 332 on the support bar 331 can monitor the weight change of the filling bucket 50 in real time, ensuring accurate weighing every time; eliminating errors caused by human factors during manual weighing, and improving the reliability and accuracy of weighing; the weighed material can be efficiently conveyed using the conveyor belt 341, significantly improving the speed and efficiency of the entire batching process, and reducing waiting time and labor costs.

[0047] Reference Figure 1 , Figure 3 and Figure 4 As shown, the lifting assembly 32 includes a vertically arranged lifting chain 321 and a lifting plate 322 connected to one side of the lifting chain 321. The lifting chain 321 is located on one side of the collection bin 31, and the lifting plate 322 is fixed to the side of the lifting chain 321 away from the collection bin 31. The dispensing bin 40 is detachably tied to the lifting plate 322. When the lifting chain 321 drives the dispensing bin 40 to rise to the upper end of the lifting chain 321, the lifting chain 321 continues to operate, causing the lifting plate 322 and the dispensing bin 40 to flip towards the side of the collection bin 31. After the material in the dispensing bin 40 has been emptied, the lifting chain 321 drives the dispensing bin 40 to descend, facilitating the replenishment of the dispensing bin 40. The design of the lifting chain 321 and the lifting plate 322 allows the dispensing bin 40 to rise smoothly to the designated position and reliably flip towards the collection bin 31 after reaching the top, ensuring the accuracy and stability of material transfer. The entire process is uniformly scheduled by controller 20, which ensures the coordination and consistency between various actions and further improves the stability and reliability of the system.

[0048] Reference Figure 1 , Figure 3 and Figure 4 As shown, the material collection hopper 31 in this application has a conical bucket design with a flared opening at the top. This effectively increases the inlet area and facilitates smooth material entry into the collection hopper 31 and downward discharge, reducing blockage. A lid can be installed at the top of the collection hopper 31 to increase its sealing performance. A discharge pipe 60 is provided at the lower outlet. The control valve 35 is installed at the discharge pipe 60 or at the bottom outlet of the collection hopper 31, making the material flow more controllable, avoiding leakage or unstable flow caused by improper valve position, and improving weighing accuracy and stability. The control valve 35 in this application can be a structure in which a cylinder or hydraulic cylinder drives the valve plate to move linearly, or it can be a structure similar to a swing door driven by a rotary cylinder or motor.

[0049] The controller 20 in this application uses a PLC controller or a microcontroller controller. A display screen 70 for displaying operating parameters is also provided on the frame 10. The controller 20 is electrically connected to the display screen 70, which also includes an alarm light 71 and an emergency button 72. The display screen 70 can be an HMI (Human Machine Interface) touchscreen or graphical interface, providing a user-friendly interface for easy input of formula parameters and monitoring of the batching process, making operation simpler and more intuitive. The entire control system in this application has data processing and communication functions, capable of receiving formula parameters and automating operation. It also includes fault detection and alarm functions to ensure the safe and stable operation of the equipment. The control system can import batching information, including raw material type, batch, weight, and quantity, to correspond one-to-one with the products. The control system can automatically identify the raw material type and batch according to the batching process, accurately controlling weighing and conveying.

[0050] Furthermore, in this application, an identification code is set on the dispensing bin 40, and a barcode reader 80 is installed on the frame 10 to read the information on the identification code. The barcode reader 80 is electrically connected to the controller 20. In this way, when the dispensing bin 40 is filled with the corresponding material and placed on the lifting plate 322, the material information corresponding to each dispensing bin 40 can be automatically identified through the identification code and the barcode reader 80 on the frame 10, thereby transmitting the relevant information to the controller 20. The controller 20 can control the weighing and conveying mechanism 30 at the corresponding position according to the required material, thus avoiding errors in human visual identification.

[0051] The implementation principle is as follows: Each distribution bin 40 in this application is used to hold different materials. The controller 20 controls the lifting component 32 to lift the distribution bin 40 according to the required weight of the materials. After the distribution bin 40 is lifted to the position, the materials in the distribution bin 40 are poured into the collection bin 31. The bottom outlet of the collection bin 31 is equipped with a control valve 35. After the controller 20 opens the control valve 35 at the bottom of the collection bin 31, the materials in the collection bin 31 can fall into the corresponding loading bin 50 below. The weighing component 33 weighs the loading bin 50. After the weighing component 33 feeds back the weighing data to the controller 20, it can calculate the weight of the materials in the loading bin 50. Based on the comparison with the predetermined requirement value, the controller 20 can continue to open or close the control valve 35, so that the weight of the materials in the loading bin 50 meets the preset requirements. Then the transmission component 34 transports the loading bin 50 and the materials in the loading bin 50 laterally.

[0052] The coordinated operation of the material collection bin 31, lifting assembly 32, weighing assembly 33, and transmission assembly 34 in this application ensures that the weight of the material in each filling bin 50 conforms to the preset value, reducing errors during manual weighing and improving the accuracy and consistency of weighing. The automated weighing and batching process replaces traditional manual operation, significantly improving batching speed and work efficiency, and reducing labor costs and labor intensity. The controller 20 can automatically identify the type and batch of raw materials and monitor and adjust the weighing process in real time, ensuring accurate recording and management of batching information and avoiding the possibility of errors in manual recording. The device in this application supports the free combination and precise control of various materials, meeting the needs of different product models and customers, and possesses high flexibility and applicability.

[0053] In this application, after the ingredient information is transmitted to the control system, the control system can automatically identify the required raw material type and batch according to the ingredient process, and accurately control the weighing and conveying. Then, through the identification code on the dispensing bin 40 and the barcode reader 80 on the frame 10, the raw material type and batch are automatically identified, thereby controlling the corresponding dispensing bin 40 and weighing conveying mechanism 30 to perform corresponding actions. The corresponding lifting mechanism pours the material into the corresponding collection bin 31, and accurately weighs it according to the weight required by the ingredient process. After weighing, the filling bin 50 is transported to the corresponding position via the conveying component 34. The entire process reduces errors from manual recording, improves the accuracy and consistency of ingredient preparation, and greatly enhances the efficiency and reliability of ingredient preparation.

[0054] The device in this application can collect weighing data and material information from each set of weighing and conveying mechanisms 30 in real time. The collected data needs to be processed and analyzed to improve the control accuracy of the batching process. Data processing may include correction and compensation to eliminate errors and deviations in the weighing components 33. At the same time, the batching process can be optimized and improved through methods such as statistical analysis and trend prediction.

[0055] Example 2

[0056] This embodiment is largely the same as Embodiment 1, except that the lifting assembly 32 in this embodiment includes a vertically arranged lifting chain 321 and a lifting plate 322 connected to one side of the lifting chain 321. The lifting chain 321 is located on one side of the collection bin 31, and one side of the lifting plate 322 is hinged to the lifting chain 321. The dispensing bin 40 is detachably tied to the lifting plate 322. A pushing member is provided on the frame 10 or the lifting chain 321 for pushing the lifting plate 322 and the dispensing bin 40 to flip toward the side of the collection bin 31. The pushing member can be a cylinder or a hydraulic cylinder. For example, the pushing member is a hydraulic cylinder. The housing of the pushing member is hinged to the lifting chain 321, and the output shaft end of the pushing member is hinged to the lifting plate 322. After the lifting plate 322 carries the dispensing bin 40 to the correct position, the pushing member pushes the lifting plate 322 to swing toward the side of the collection bin 31, thereby pouring the material in the dispensing bin 40 into the corresponding collection bin 31. This structure also achieves the goal of automatically flipping and pouring the material in the distribution bucket 40 into the collection bucket 31 after it rises to the correct position. Moreover, the installation structure is more convenient and flexible, improving the efficiency and accuracy of material transfer. The entire device has a high level of automation, while also ensuring the accuracy and consistency of the weighing and batching process.
