Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery material technology, specifically to a bowl-filling system. Background Technology
[0002] In the field of lithium-ion battery powder manufacturing, the filling machine is a key piece of equipment used to quantitatively load raw materials into crucibles. Traditional filling machines typically employ two independent feeding and filling ports, each controlled by an independent PLC (Programmable Logic Controller) system, and the feeding weight is controlled by a preset single formula. This design results in completely consistent raw material filling amounts across all crucibles.
[0003] However, during the subsequent sintering process in the kiln, the uniformity of heating varied significantly due to the different placement of the saggers. This uneven heating not only affected the consistency of product quality but also limited the overall production capacity because the amount of saggers could not be adjusted for differentiating factors. Utility Model Content
[0004] In view of this, the present invention provides a sagger loading system to solve the problem that, during the subsequent kiln sintering process, the uneven heating is significantly different due to the different placement of the saggers. This uneven heating not only affects the consistency of product quality, but also limits the improvement of overall production capacity because the amount of saggers cannot be adjusted in a differentiated manner.
[0005] This utility model provides a bowl-filling system, including:
[0006] A conveyor line, wherein a first filling position and a second filling position are provided on the conveyor line;
[0007] The first sagger loading machine is installed on one side of the conveyor line corresponding to the first sagger loading position. The first sagger loading machine loads materials into the sagger loading position.
[0008] The second potting machine is installed on one side of the conveyor line corresponding to the second potting position;
[0009] The second sagger filling machine includes a feeding structure, the feeding end of which faces the second sagger filling position, and the feeding structure is configured to fill the sagger filling position with a number of materials of different weights.
[0010] Beneficial Effects: The above settings solve the problem of uneven heating within the kiln leading to inconsistent residual rates. The second sagger loading machine dynamically switches the input weight of the material in the saggers at the second loading position, implementing differentiated loading for the lower saggers of the large sagger group fed into the kiln for sintering. This ensures that the lower saggers in the first and fourth columns are filled with more material of the first formula, and that the first sagger loading machine, in conjunction with the upper saggers in the first to fourth columns, also fills them with more material of the first formula. These saggers can fully contact the heat source within the kiln, utilizing excess heat capacity to increase production capacity. However, the lower saggers in the second and third columns are located in the middle of the large sagger group fed into the kiln for sintering and cannot fully contact the heat source. Therefore, the loading structure of the second sagger loading machine fills the lower saggers in the second and third columns with less material of the second formula, effectively reducing the residual rate after sintering and improving the overall consistency of sintering quality.
[0011] In one alternative implementation, the loading structure includes:
[0012] The first hopper is installed above the second filling position;
[0013] The first feeding cup has one end installed at the lower end of the first feeding hopper and the other end facing the second feeding bowl position;
[0014] An adjustment component is installed on the first hopper and is used to adjust the material filling amount of the sagger facing the second sagger position.
[0015] In one alternative implementation, the regulating component includes:
[0016] A power unit is fixed on the first hopper, and the output end of the power unit is located inside the first hopper;
[0017] A spiral adjusting component is fixed on the first feeding hopper. One end of the spiral adjusting component is connected to the output end of the power unit, and the other end extends into the first feeding cup.
[0018] Beneficial effects: It can not only control the filling amount of the sagger in the second filling position, but also control the filling speed of the sagger in the second filling position. In conjunction with the sagger in the first filling position, it can make the filling time of the sagger in the two filling positions the same, avoiding the situation where one sagger is filled while the other is not, thus avoiding the waste of time and improving the production rate.
[0019] In one alternative embodiment, the loading structure includes at least two loading hoppers disposed above the second loading position;
[0020] The rate at which material is filled in any one hopper is different from the rate at which material is filled in the other hoppers.
[0021] In one alternative implementation, the loading structure includes:
[0022] The system comprises a second hopper, a third hopper, and a fourth hopper. The lower end of the second hopper is equipped with a second filling cup, the lower end of the third hopper is equipped with a third filling cup, and the lower end of the fourth hopper is equipped with a fourth filling cup.
[0023] In one alternative embodiment, the inner diameter of the third filling cup is larger than the inner diameter of the fourth filling cup, but smaller than the inner diameter of the second filling cup.
[0024] Beneficial effects: When it is necessary to fill the sagger of the second filling position with materials of the first formula, the second formula, or other formulas, one or more combinations of valves below the second, third, and fourth filling cups can be opened to control the material filling speed of the sagger of the second filling position. In conjunction with the sagger of the first filling position, the filling time of the saggers of the two filling positions is the same, avoiding the situation where one sagger is filled while the other is not, thus avoiding the waste of time and improving the production rate.
[0025] In one alternative embodiment, valves are installed near the lower ends of the second, third, and fourth filling cups, close to the conveyor line.
[0026] In one alternative embodiment, a handling device is also provided at the end of the conveyor line for handling the sagger.
[0027] In one alternative implementation, the first potting machine is controlled by a PLC, and the second potting machine is controlled by an HMI.
[0028] In one alternative embodiment, the potting system further includes a limiting structure installed on the conveyor line corresponding to the first potting position or the second potting position. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0039] In the field of lithium-ion battery powder manufacturing, the filling machine is a key piece of equipment used to quantitatively load raw materials into crucibles. Traditional filling machines typically employ two independent feeding and filling ports, each controlled by an independent PLC (Programmable Logic Controller) system, and the feeding weight is controlled by a preset single formula. This design results in completely consistent raw material filling amounts across all crucibles.
[0040] However, during the subsequent sintering process in the kiln, the uniformity of heating varied significantly due to the different placement of the saggers. This uneven heating not only affected the consistency of product quality but also limited the overall production capacity because the amount of saggers could not be adjusted for differentiating factors.
[0041] To solve the above technical problems, the following will be combined with... Figures 1 to 4 The following describes embodiments of the present invention.
[0042] According to an embodiment of the present invention, a potting system is provided, comprising: a conveyor line 1, a first potting machine 2, and a second potting machine 3. Figure 1 The arrow on the conveyor line points in the first direction.
[0043] like Figures 1 to 3 As shown, conveyor line 1 transports saggers along a first direction, and conveyor line 1 is provided with a first sagger position 11 and a second sagger position 12. A first sagger loading machine 2 is installed on one side of conveyor line 1 corresponding to the first sagger position 11, and the first sagger loading machine 2 loads material into the saggers at the first sagger position 11. A second sagger loading machine 3 is installed on one side of conveyor line 12 corresponding to the second sagger position 12, and the second sagger loading machine 3 loads material into the saggers at the second sagger position 12. The second sagger loading machine 3 includes a loading structure, the loading end of which faces the second sagger position 12, and the loading structure is configured to fill the saggers at the second sagger position 12 with materials of several different weights.
[0044] When conveyor line 1 transports saggers, it typically transports them in groups of two empty saggers, with the two empty saggers in a group placed alternately on conveyor line 1. Conveyor line 1 stops when the two empty saggers reach the first loading position 11 and the second loading position 12, respectively. The first loading machine 2 fills the sagger at the first loading position 11 with material. In this embodiment, the first loading machine 2 fills the sagger at the first loading position 11 with a fixed weight of material. The loading structure in the second loading position 12 fills the empty sagger at the second loading position 12 with material. The loading structure in the second loading position 12 can selectively fill the sagger at the second loading position 12 with different weights of material. For example, the sagger group entering the kiln for sintering has eight saggers, arranged in two stacked layers, with four rows of saggers along the first direction. In the first set of saggers conveyed on conveyor line 1, the first sagger loading machine 2 and the second sagger loading machine 3 respectively fill two saggers with a larger weight of the first formula material. After conveyor line 1 conveys the two saggers of this set to the end point, they are stacked, with the sagger corresponding to the second sagger loading machine 3 at the bottom and the sagger corresponding to the first sagger loading machine 2 at the top, forming a two-layered group of small saggers. In the second set of saggers conveyed on conveyor line 1, the first sagger loading machine 2 fills the sagger at the first sagger loading position 11 with a larger weight of the first formula material, and the second sagger loading machine 3 fills the sagger at the second sagger loading position 12 with a smaller weight of the second formula material. After conveyor line 1 conveys the two saggers of this set to the end point, they are stacked, with the sagger corresponding to the second sagger loading machine 3 at the bottom and the sagger corresponding to the first sagger loading machine 2 at the top, forming a two-layered group of small saggers. In the third group of saggers conveyed by conveyor line 1, the first sagger loading machine 2 fills the sagger at the first loading position 11 with a larger weight of the first formula material, while the second sagger loading machine 3 fills the sagger at the second loading position 12 with a smaller weight of the second formula material. After conveyor line 1 transports the two saggers of this group to the end point, they are stacked, with the sagger corresponding to the second sagger loading machine 3 at the bottom and the sagger corresponding to the first sagger loading machine 2 at the top, forming a two-layered row of small saggers. In the fourth group of saggers conveyed by conveyor line 1, the first sagger loading machine 2 and the second sagger loading machine 3 each fill two saggers with a larger weight of the first formula material. After conveyor line 1 transports the two saggers of this group to the end point, they are stacked, with the sagger corresponding to the second sagger loading machine 3 at the bottom and the sagger corresponding to the first sagger loading machine 2 at the top, forming a two-layered row of small saggers. Finally, the four small saggers are arranged in sequence to form a two-layered, four-row large sagger group before being fed into the kiln for sintering. Four groups, totaling eight saggers, constitute one cycle.
[0045] By implementing the above settings, the problem of uneven heating within the kiln leading to inconsistent residual rates is resolved. The second loading machine 3 dynamically switches the input weight of the material in the saggers at the second loading position 12, thus implementing differentiated loading for the lower saggers of the large sagger group fed into the kiln for sintering. This ensures that the lower saggers in the first and fourth columns are filled with a larger amount of the first formula material, and that the first loading machine 2, in conjunction with the first to fourth columns, fills the upper saggers with a larger amount of the first formula material. These saggers in these positions can fully contact the heat source within the kiln, utilizing excess heat capacity to increase production capacity. However, the lower saggers in the second and third columns are located in the middle of the large sagger group fed into the kiln for sintering and cannot fully contact the heat source. Therefore, the loading structure within the second loading machine 3 fills the lower saggers in the second and third columns with a smaller amount of the second formula material, effectively reducing the residual rate after sintering and improving the overall consistency of sintering quality.
[0046] Specifically, in one embodiment, such as Figures 1 to 3 As shown, the loading structure includes a first loading hopper 31, a first loading cup 311, and an adjusting component 32. The second loading machine 3 has a base frame, with the conveyor line 1 passing through it. The first loading hopper 31 is mounted on the base frame and positioned directly above the second loading position 12. The upper end of the first loading hopper 31 is closed, leaving a feed inlet. The first loading cup 311 is tubular, with one end fixed to the lower section of the first loading hopper 31 and the other end facing the second loading position 12. The entire first loading cup 311 is vertically arranged. The first loading hopper 31 is connected to the first loading cup 311. The adjusting component 32 is mounted on the first loading hopper 31 and is used to adjust the filling amount of material towards the sagger in the second loading position 12. Specifically, the adjustment component 32 includes a power unit 321 and a screw adjustment component 322. The power unit 321 is a rotary motor and is installed on the first hopper 31. The output end of the power unit 321 passes through the upper wall of the first hopper 31 and extends downward into the first hopper 31. The screw adjustment component 322 is an auger and is vertically installed in the first filling cup 311. One end of the screw adjustment component 322 is fixed to the output end of the power unit 321, and the other end of the screw adjustment component 322 is rotatably connected to the discharge port of the first filling cup 311.
[0047] When the sagger in the second filling position 12 needs to be filled, the power unit 321 drives the screw adjusting component 322 to rotate along the axis of the first filling cup 311. The material is then spiraled out from the space between the screw adjusting component 322 and the first filling cup 311. By adjusting the rotation speed of the power unit 321, the output amount of the material is controlled, thereby controlling the filling amount of the sagger in the second filling position 12. Through the above settings, the rotation speed of the screw adjusting component 322 is controlled in real time by the power unit 321, enabling the output of different weights of material from the same filling structure. The rotation speed and the amount of material fed are linearly related, resulting in high control precision. The screw blades forcefully push the powder, avoiding clogging problems caused by free-falling material.
[0048] Furthermore, through the above settings, not only can the filling amount of the sagger in the second filling position 12 be controlled, but also the material filling speed of the sagger in the second filling position 12 can be controlled. In conjunction with the sagger in the first filling position 11, the filling time of the saggers in the two filling positions is the same, avoiding the situation where one sagger is filled while the other sagger is not filled, thus avoiding the waste of time and improving the production rate.
[0049] At the same time, the above-mentioned loading structure can also be installed in the first loading machine 2 to load the empty saggers in the first loading position 11.
[0050] In another embodiment, such as Figure 1 and Figure 4 As shown, the loading structure includes a second loading hopper 33, a third loading hopper 34, and a fourth loading hopper 35. These three hoppers are arranged side-by-side in a horizontal direction and are all located above the second loading position 12. A second loading cup 331 is installed at the lower end of the second loading hopper 33, a third loading cup 341 is installed at the lower end of the third loading hopper 34, and a fourth loading cup 351 is installed at the lower end of the fourth loading hopper 35. All three loading cups (331, 341, and 351) are arranged vertically, and their inner diameters decrease sequentially. Valves are installed near the lower ends of each loading cup (331, 341, and 351) close to the conveyor line 1.
[0051] With the above settings, when it is necessary to fill the sagger of the second filling position 12 with materials of the first formula, the second formula, or other formulas, one or more combinations of valves below the second filling cup 331, the third filling cup 341, and the fourth filling cup 351 can be opened to control the material filling speed of the sagger of the second filling position 12. In conjunction with the sagger of the first filling position 11, the filling time of the saggers of the two filling positions is the same, avoiding the situation where one sagger is filled while the other sagger is not, thus avoiding the waste of time and improving the production rate.
[0052] In the above embodiment, a handling device (not shown in the figure) is also provided at the end of the conveyor line 1. The handling device is used to handle the crucibles. The handling device can be a robotic arm, which handles and stacks two corresponding crucibles on the conveyor line 1 to form a double-layer small crucible group, and then handles and fits the small crucible group together to form a large crucible group. This eliminates manual intervention, improves handling speed and accuracy, and avoids fluctuations in the residual inspection rate caused by manual stacking misalignment.
[0053] In the above embodiments, the first filling machine 2 is controlled by a PLC, and the second filling machine 3 is controlled by an HMI. The PLC control of the first filling machine 2 ensures a fixed formula execution, guaranteeing absolute consistency in the weight of the upper saggers. The HMI control of the second filling machine 3 allows for dynamic formula switching, enabling rapid manual intervention. The HMI interface visualizes the formula sequence, allowing operators to verify it in real time.
[0054] In the above embodiments, such as Figure 2 and Figure 4 As shown, the sagger filling system also includes a limiting structure 13, which is installed on the conveyor line 1 corresponding to the first sagger filling position 11 or the second sagger filling position 12. For example, limiting plates can be placed on both sides of the conveyor line 1, with the distance between the two limiting plates equal to the width of the sagger, thereby limiting the lateral displacement of the sagger and ensuring that the sagger can correctly stop at the first sagger filling position 11 or the second sagger filling position 12, providing a physical basis for filling accuracy.
[0055] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
