Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cartoning and feeding mechanisms, specifically a silicon material cartoning and feeding mechanism. Background Technology
[0002] Silicon material boxing and feeding systems are key equipment in the photovoltaic and semiconductor industries for the efficient and precise handling of silicon materials. They are primarily used to automatically load silicon materials (such as polycrystalline silicon blocks and ingots) into process boxes and transport them to downstream production stages (such as ingot casting and crystal pulling). These systems typically include automatic sorting, weighing, boxing, sealing, and conveying modules, integrating visual recognition or sensor technology to ensure accurate silicon material positioning and prevent contamination and damage. Their core advantages lie in improved feeding efficiency, reduced manual intervention, and lower risk of impurity introduction, while also supporting data traceability and meeting high-cleanliness process requirements. They represent an important automated solution for the front-end processing of silicon materials in intelligent manufacturing.
[0003] The existing technology, patent application number 201922412901.2, entitled "An Intelligent Feeding System," includes a first AGV trolley, a conveying system, a vertical storage system, and a feeding system. The first AGV trolley is used to deliver silicon material to the conveying system; the conveying system is used to deliver the silicon material into the vertical storage system; and the feeding system is used to retrieve and feed material from the vertical storage system. This utility model sets up a feeding system to minimize employee contact with silicon material through automation, thereby ensuring safety. Furthermore, automated feeding significantly improves production efficiency. However, during the boxing process, silicon material is prone to splattering and various dust particles. During the boxing intervals, the existing solution lacks a buffer system, preventing continuous and automated boxing production. Also, because there is a certain distance between the box opening and the box body, silicon material is prone to generating various silicon slag particles during the falling process, causing various silicon materials to bounce out from the gaps. Additionally, the weighing mechanism is usually connected in series with the overall equipment system; during operation, interference from other components often leads to inaccurate weighing.

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.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicon material boxing and feeding mechanism, including a belt conveyor, an installation plate fixedly connected to the outer side of the belt conveyor, a buffer feeding hopper fixedly connected to the inner side of the installation plate, a support plate provided below the belt conveyor, a tray fixedly connected to the inner side of the support plate, two card holders rotatably connected to both sides of the tray, and two limiting blocks fixedly connected to the top of the tray. Through the anti-isolation and anti-leakage mechanism, the parts of the device that come into contact with the silicon material or that may generate metal dust are effectively isolated, effectively avoiding secondary metal contamination of the silicon material and effectively preventing silicon material leakage due to jamming. Furthermore, due to the effective protection and isolation of the hinge part, the opening and closing system operates more stably and reliably.

One end of the power output shaft of the hopper opening and closing actuator passes through the mounting plate and extends to the other side of the mounting plate.

[0009] Preferably, a protective cover is fixedly connected to the bottom of the support plate, the protective cover is located outside the buffer feeding hopper, and a material box is fixedly connected to the bottom of the protective cover to contain and collect silicon material.
[0010] Preferably, a base is provided below the belt conveyor, and two air cushion vibration isolators are fixedly connected to the top of the base. The top of the air cushion vibration isolators is fixedly connected to a base plate, and vibration is reduced by the air cushion vibration isolators.

[0013] 1. The silicon material feeding and dispensing mechanism effectively isolates the parts of the device that come into contact with the silicon material or that may generate metal dust through an anti-isolation and anti-leakage mechanism. This effectively avoids secondary metal contamination of the silicon material and prevents silicon material leakage due to jamming. Furthermore, the effective protection and isolation of the hinge part makes the opening and closing system more stable and reliable in operation.
[0014] 2. The silicon material boxing and feeding mechanism uses a precise weighing mechanism to automatically detach the material box from the positioning mechanism, so that the material box no longer rubs or collides with other mechanisms during the weighing process, thereby greatly improving the weighing accuracy of the silicon material.

Detailed Implementation
[0022] 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.
[0023] Example 1: Please refer to again Figure 1-6 This utility model provides a silicon material boxing and feeding mechanism, including a belt conveyor 100. A mounting plate 110 is fixedly connected to the outer side of the belt conveyor 100. A buffer feeding hopper 120 is fixedly connected to the inner side of the mounting plate 110. A hopper opening and closing actuator 130 is fixedly connected to the outer side of the mounting plate 110. One end of the power output shaft of the hopper opening and closing actuator 130 passes through the mounting plate 110 and extends to the other side of the mounting plate 110. The power output shaft of the hopper opening and closing actuator 130 is fixedly connected to... There is an opening and closing hopper 131. Four connecting rods 140 are fixedly connected to the bottom of the mounting plate 110. The bottom end of the connecting rods 140 is fixedly connected to the bearing plate 141. Two tension sensors 150 are fixedly connected to both sides of the mounting plate 110. The bottom of the tension sensors 150 is fixedly connected to the bearing plate 141. A protective cover 160 is fixedly connected to the bottom of the bearing plate 141. The protective cover 160 is located outside the buffer feeding hopper 120. A material box 170 is fixedly connected to the bottom of the protective cover 160.
[0024] Specifically, the silicon material is conveyed to the buffer feeding hopper 120 by the belt conveyor 100. The buffer feeding hopper 120 collects the silicon material. When the silicon material accumulates to a certain extent in the buffer feeding hopper 120, the tension sensor 150 sends a start command to the hopper opening and closing actuator 130, causing the hopper opening and closing actuator 130 to open and close the hopper 131. The silicon material in the buffer feeding hopper 120 falls into the material box 170 through the protective cover 160. During this process, the silicon material is conveyed in a sealed manner to isolate it and prevent leakage.
[0025] Example 2: Please refer to again Figure 1-6A support plate 200 is provided below the belt conveyor 100. A tray 210 is fixedly connected to the inner side of the support plate 200. Two card holders 220 are rotatably connected to both sides of the tray 210. Two limit blocks 230 are fixedly connected to the top of the tray 210. A base 300 is provided below the belt conveyor 100. Two air cushion vibration isolators 310 are fixedly connected to the top of the base 300. A base plate 320 is fixedly connected to the top of the air cushion vibration isolator 310. A lifting cylinder 330 is fixedly connected to the top of the base 300. The top of the lifting cylinder 330 passes through the base plate 320 and extends to the top of the base plate 320. Two pressing rods 340 are fixedly connected to the top of the base plate 320. A weighing sensor 350 is fixedly connected to the top of the lifting cylinder 330. The weighing sensor 350 is fixedly connected to the pressing rod 340. A positioning plate 351 is fixedly connected to the top of the weighing sensor 350.
[0026] Specifically, when the material bin 170 is weighing, it applies pressure to the card holder 220 installed on the tray 210, causing the card holder 220 to rotate and deform. Then, the bottom end of the card holder 220 applies pressure to the positioning plate 351 below, causing the positioning plate 351 to apply pressure to the weighing sensor 350 below, causing the weighing sensor 350 to weigh the silicon material inside the material bin 170. During this process, the material bin 170 no longer rubs or collides with other mechanisms, thereby greatly improving the weighing accuracy of the silicon material.
[0027] Working principle: Silicon material is conveyed to the buffer feeding hopper 120 by the belt conveyor 100. The buffer feeding hopper 120 collects the silicon material. When the silicon material accumulates to a certain level in the buffer feeding hopper 120, the tension sensor 150 sends a start command to the hopper opening and closing actuator 130, causing the hopper opening and closing actuator 130 to open and close the hopper 131. The silicon material in the buffer feeding hopper 120 falls into the material box 170 through the protective cover 160. During this process, the silicon material is conveyed in a sealed manner to isolate it and prevent leakage.
[0028] When the material bin 170 is weighing, it applies pressure to the card holder 220 installed on the tray 210, causing the card holder 220 to rotate and deform. Then, the bottom end of the card holder 220 applies pressure to the positioning plate 351 below, causing the positioning plate 351 to apply pressure to the weighing sensor 350 below, causing the weighing sensor 350 to weigh the silicon material inside the material bin 170. During this process, the material bin 170 no longer rubs or collides with other mechanisms, thereby greatly improving the weighing accuracy of the silicon material.
