Description

Technical Field

[0001] The present application relates to a battery production line, in particular to a battery production line that can integrate multiple processes including drying, liquid injection, formation, and constant temperature standing in one production line. The production line has a higher degree of integration and can reduce the space occupied by the battery production line. Background Art

[0002] Batteries are a key component of modern power equipment and are widely used in various fields, including electric vehicles, mobile devices, and smart home appliances. With the continuous advancement of battery technology, the requirements for battery production lines are also increasing. The integration and space utilization of battery production lines are particularly important. Generally speaking, the battery production process includes multiple key steps such as drying, filling, formation, and constant temperature stabilization. These steps are usually carried out on multiple independent production lines.

[0003] However, existing battery production technology presents numerous challenges and shortcomings. First, existing battery production lines typically require multiple separate production lines for drying, filling, formation, and constant temperature stabilization. This not only consumes significant production space but also increases equipment acquisition and maintenance costs. Furthermore, the transfer of materials between production lines increases production time and energy consumption, reducing efficiency.

[0004] Secondly, because existing battery production lines require material transfer between multiple processes, this process can introduce contamination, impacting battery performance and reliability. Furthermore, each material transfer requires the production line to be started and shut down, which not only increases the complexity of the production process but can also impact line stability.

[0005] In view of the above problems, developing a more integrated battery production line is of great significance for improving the competitiveness of the battery industry and meeting society's demand for more efficient and environmentally friendly batteries. Summary of the Invention

[0056] like Figure 1-13 As shown, this embodiment discloses a highly efficient, space- and energy-saving, multi-process battery production line. This design primarily integrates drying, liquid injection, formation, and constant temperature stabilization processes into a single integrated production line, thereby reducing the space occupied by the battery production line, improving production efficiency, reducing energy consumption, and minimizing pollution risks and production process complexity.

[0057] In this embodiment, the battery production line includes an integrated equipment group 1, a material handling assembly 2 located on one side of the integrated equipment group 1, and a controller 3 connected to the integrated equipment group 1 and the material handling assembly 2. The material handling assembly 2 is controlled by the controller 3 and is used to perform material handling operations in the integrated equipment group 1.

[0058] In this embodiment, as a key component for automated production, the material handling assembly 2 includes a guide rail 13 and a material handling mechanism 14 mounted on and linearly moving along the guide rail 13 to facilitate material handling within the integrated device 4. Preferably, and for cost-conscious considerations, a stacker can be used for this mechanism, with its bottom wheels cooperating with the guide rail 13 to enable controlled linear motion along the guide rail 13. It should be understood that, depending on actual needs, the material handling mechanism 14 can also utilize automated equipment such as a multi-axis robotic arm. The specific type and form of mechanical equipment used are not further detailed.

[0059] In this embodiment, the integrated device group 1 includes at least two integrated devices 4, each of which is connected to a controller 3 and controlled by the controller 3. As a preferred embodiment, the integrated device group 1 has an even number of integrated devices 4, with two integrated devices 4 arranged one above the other to form an integrated device unit 12. Multiple integrated device units 12 are arranged in a straight line, forming a linear battery production line.

[0060] It should be understood that arranging the integrated devices 4 up and down to form the integrated device unit 12 is to improve the vertical space utilization to save horizontal space occupation, and it is not a unique arrangement structure. For example, multiple integrated devices 4 can also be arranged horizontally in a straight line.

[0061] In this embodiment, each integrated device 4 includes a vacuum chamber 6 and an automatic door 17 that cooperates with the vacuum chamber. The vacuum chamber 6 of the integrated device 4 can be opened and closed by the automatic door 17. The automatic door 17 is controlled by the controller 3 and can be linked with the material handling assembly 2 to automatically feed and unload materials, meeting the requirements of automated production.

[0062] It should be understood that the automatic door 17 can be used in a suitable form and mechanism according to the needs, for example, referring to the automatic door used in the existing battery oven.

[0063] In this embodiment, the vacuum chamber 6 contains a heat exchange assembly composed of several parallel heat exchange baffles 7 with heat exchange channels. Two adjacent heat exchange baffles 7 in the heat exchange assembly cooperate to form a work station 16 for placing the battery product 20. The battery product 20 is moved into the work station 16 by the loading and unloading assembly 2. After processing, the battery semi-finished product is removed from the work station 16 by the loading and unloading assembly 2. In order to realize the processing of the battery product 20, the work station 16 has a liquid injection assembly with multiple liquid injection ports 8 and a plurality of formation assemblies for the conductive pins 9. The heat exchange channel of the heat exchange assembly is connected to the cold source 10 and the heat source 11, so that the heat exchange assembly has the temperature control function of heating and cooling. Figure 11 As shown, the cold source 10 and the heat source 11 are connected in series and connected to the heat exchange channels in each heat exchange baffle 7 in the heat exchange component through a pipe. For example, the heat source 11 is a mold temperature controller controlled by a controller, which is connected to the heat exchange channel through a pipe with a valve, and provides a heat exchange medium, such as water or oil, to the heat exchange channel as needed. Similarly, the cold source 10 can also be set in the integrated device 4, connected to the heat exchange channel of the heat exchange component to enable the heat exchange component to have a cooling function. The cold source 10 can be a water chiller controlled by the controller 3, which is connected to the heat exchange channel through a pipe with a valve, and provides a heat exchange medium, such as water or oil, to the heat exchange channel as needed.

[0064] It should be understood that since both the heat source 11 and the cold source 10 need to cooperate with the heat exchange flow channel, the medium used by the two needs to be consistent. Otherwise, when the heat source 11 or the cold source 10 is working, the medium will mix, which may have an adverse effect on the equipment. When water is selected as the medium, it is necessary to consider the problem of increased pipe pressure after the water is heated. Therefore, when using water as the medium, an exhaust valve needs to be set to ensure the safe operation of the equipment. The specific use and arrangement of the pipeline is a technology well known to those skilled in the art. You can refer to the specific pipeline layout of the liquid bath battery oven. In this embodiment, no detailed description is given.

[0065] It should be understood that the movement of the bottom wheel necessarily requires the use of a drive unit, such as a drive motor.

[0066] It should also be understood that the layout of the guide rails 13 is consistent with the layout of the integrated devices 4, so that the material handling mechanism 14 can be aligned with each integrated device 4. In addition, the production line will also cooperate with the material handling mechanism 14 and the discharge device 15. However, the material handling mechanism 14 and the discharge device 15 are both well-known technologies in the field. Those skilled in the art can select the specific structure and form according to actual use needs. The two devices shown in the drawings are only to better conform to the actual production line situation and facilitate understanding of this technology. The two devices are not essential components of this application.

[0067] In this embodiment, in order to achieve a low vacuum environment, each integrated device 4 is independently connected to a vacuum device (not shown in the figure). For example, each vacuum chamber is connected to a screw pump, and the screw pump is used to achieve negative pressure in the vacuum chamber 6 in a sealed state.

[0068] It should be understood that each of the multiple integrated devices 4 can be connected to a vacuum device, through which the negative pressure of the vacuum chamber 6 of the multiple integrated devices 4 can be achieved. The specific connection method is selected according to the load capacity of the vacuum device and the actual size and load requirements of each vacuum chamber 6.

[0069] In this embodiment, in order to meet the needs of formation, the production line includes at least one battery formation power supply 23, which is connected to the formation components in each integrated device 4 and is used to provide power during the formation step.

[0070] In this embodiment, in order to realize the liquid injection and formation of the battery product 20, the liquid injection component and the formation component can be actively raised and lowered in the working position under the control of the controller 3. The upgrade is completed by a driving mechanism 19 controlled by the controller 3. More specifically, the liquid injection component and the formation component are fixedly mounted on a frame, and the frame is driven to move by a driving mechanism 19 including a motor and a screw, so that the two components can be controlled to connect and cooperate with the battery product 20 in the working position 16.

[0071] In this embodiment, if Figure 9 As shown, the liquid injection assembly has multiple liquid injection ports 8 for injecting liquid into the battery product 20. Each liquid injection port 8 is actually connected to the liquid injection pump 22 through a pipeline, and an electric control valve 21 controlled by the controller 3 is provided on the pipeline.

[0072] It is important to understand that if Figure 9As shown, each injection port 8 is connected to an independent injection pump 22. That is, each injection head 8 is equipped with an injection pump 22, enabling simultaneous injection of liquid from multiple injection ports 8. This maximizes injection efficiency and saves injection time. In practice, for cost considerations, each number of injection ports 8 is connected to an injection pump 22 via a pipe with an electronically controlled valve. The valve and the injection pump cooperate to selectively inject liquid. This achieves higher injection efficiency at a lower cost.

[0073] It should be understood that the injection pump is a well-known technology in the art, and suitable specifications and models can be selected according to actual use needs, so the specific structure of the injection pump will not be described in detail.

[0074] In this embodiment, there are multiple groups of conductive pins 9 in the formation assembly, which make electrical contact with the preset upper poles of the battery product 20 when descending, and perform controllable charging and activation on the battery product 20 to achieve the purpose of battery formation.

[0075] It should be understood that the main steps of battery formation generally include the following stages: Pre-charging stage: This is the initial stage of battery formation, and its main purpose is to activate the active materials in the battery and prepare for subsequent charge and discharge reactions. In this stage, the battery will be charged at a lower current to prevent overheating or other harmful reactions. Constant current charging stage: After pre-charging, the battery will enter the constant current charging stage. In this stage, the battery will be charged at a constant current until the battery voltage reaches a preset upper limit. After the battery voltage reaches the preset upper limit, the battery will enter the constant voltage charging stage. In this stage, the battery voltage will be maintained at the preset upper limit, and the charging current will gradually decrease. The above-mentioned formation process is mainly controlled by the battery formation power supply, and the battery formation power supply is a mature technology in this field. The specific circuit, structure, and working principle are based on the principle of simplicity and will not be described again.

[0076] In general, the design of this multi-process battery production line enables multiple processes such as drying, liquid injection, formation, and constant temperature standing to be smoothly implemented in a single integrated production line, thus bringing many advantages. First, such a design greatly reduces the space occupied by the battery production line, because multiple processes can be completed in a set of integrated equipment without the need to set up separate equipment for each process. Secondly, this design improves production efficiency. Since the material transfer time between processes is reduced, the production speed is increased. At the same time, this design also reduces energy consumption, because each device can share heat and cold sources to a certain extent, which is more energy efficient than each device requiring a separate heat and cold source. In addition, this design also reduces the risk of contamination and the complexity of the production process, because all processes are carried out in a closed system, reducing the chance of material exposure and reducing the complexity of operations. Example

[0077] like Figure 14 As shown, the difference between this embodiment and embodiment 1 is that the liquid injection port 8 in the liquid injection assembly and the normally connected pipeline connected thereto, that is, the connecting pipe section between the electric control valve 21 and the liquid injection port 8, are further connected to a device 24 for treating residual liquid. The device 24 is selected from a negative pressure air device or a positive pressure air device. When the positive pressure air device is selected, at the final stage of liquid injection, the residual liquid in the liquid injection port 8 and the pipeline normally connected thereto is blown out by a high-pressure air flow, ensuring that after the liquid injection is completed, no liquid remains in the liquid injection port 8 and the pipeline normally connected thereto. When the negative pressure air device is selected, after the liquid injection is completed, the residual liquid in the liquid injection port 8 and the pipeline normally connected thereto is sucked out by the negative pressure air device, ensuring that after the liquid injection is completed, no liquid remains in the liquid injection port 8 and the pipeline normally connected thereto.

[0078] It should be understood that the use of positive pressure air equipment is to blow the residual liquid into the battery product 20 to be injected, and its operation is started at the end of the liquid injection after the injection pump 22 is closed, while the pipeline normally connected using negative pressure air refers to a pipeline without valves or restrictions, and the pipeline and the injection port 8 can be freely connected. Example

[0079] like Figure 15 As shown, the difference between this embodiment and embodiment 1 is that the heat exchange baffle 7 in the heat exchange assembly is not connected to the heat source 11. That is, in this embodiment, all piping structures connected to the heat source 11 are removed, and correspondingly, the heating of the heat exchange baffle 7 is achieved by an electric heating assembly 25 built into the heat exchange baffle 7. The electric heating assembly 25 is controlled, for example, it is physically connected to the controller 3 and is controlled by the controller 3. The electric heating assembly 25 is composed of at least one PTC heating plate or at least one electric heating wire. Through reasonable arrangement, the surface of the heat exchange baffle 7 is evenly heated. Replacing the heat source 11 with the electric heating assembly 25 can simplify the structure and realize temperature control of different heat exchange baffles 7 in a single device, further improving the flexibility of use.

[0080] It should be understood that the electric heating component 25 should not be understood as a better solution for the heat source 11.
