Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery production, and in particular to a formation fixture and formation device based on fluid medium temperature regulation. Background Technology

[0002] After the lithium battery cells are packaged, they need to undergo formation and capacity testing. When the cell modules are formed, they need to undergo temperature control.

[0003] Existing formation devices generally use heating tubes or heating plates to regulate the temperature of the battery cell modules.

[0004] However, the heating element or heating plate only has the function of heating, which makes it impossible for the battery cell module to reach a temperature below room temperature. Since the temperature requirements for different battery cell manufacturing processes are different, the formation device cannot be adapted to temperature control below room temperature, thereby reducing the adaptability of the formation device. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a chemical formation fixture based on fluid medium temperature control, which can improve the temperature regulation range and thus improve the adaptability of the chemical formation device.

[0006] This invention also proposes a chemical formation apparatus having the above-mentioned chemical formation fixture based on fluid medium temperature regulation.

[0007] According to a first aspect embodiment of the present invention, a chemical formation fixture based on fluid medium temperature control includes:

[0008] A clamping element for clamping battery cells, having a medium flow channel for circulating a temperature-regulating medium;

[0009] A medium inlet pipe is connected to the input end of the medium flow channel and is used to input the temperature-regulating medium into the medium flow channel;

[0010] A medium outlet pipe is connected to the output end of the medium flow channel and is used to output the temperature-regulating medium from the medium flow channel.

[0011] The chemical formation fixture based on fluid medium temperature control according to the embodiments of this utility model has at least the following beneficial effects:

[0012] This invention incorporates a medium flow channel within the clamping component. A temperature-regulating medium is input into the medium flow channel via an inlet pipe and output via an outlet pipe. This allows the temperature-regulating medium to flow within the channel. By inputting temperature-regulating media of different temperatures into the medium flow channel, bidirectional temperature regulation of the clamping component (heating and cooling) can be achieved. Consequently, bidirectional temperature regulation of the battery cell (heating and cooling) by the clamping component is realized. Compared to existing heating elements or heating plates that can only heat the battery, this solution, through the flowing temperature-regulating medium, can control the battery cell temperature below or above room temperature, increasing the temperature regulation range and significantly improving the temperature adaptability of the formation device, thus meeting the differentiated needs of different battery cell manufacturing processes.

[0013] According to some embodiments of the present invention, the chemical formation fixture based on fluid medium temperature control further includes a mold temperature controller, which is connected to the medium inflow pipe and is used to adjust the temperature of the temperature-regulating medium input into the medium flow channel.

[0014] The advantages are: by setting up a mold temperature controller, which is connected to the medium inflow pipe, the mold temperature controller is used to adjust the temperature of the temperature-regulating medium in the input medium flow channel. It can be understood that by connecting the mold temperature controller to the medium inflow pipe, precise control of the input temperature of the temperature-regulating medium is achieved. The mold temperature controller can actively adjust the temperature of the temperature-regulating medium according to the needs, such as cooling or heating, further enhancing the temperature regulation range and efficiency, while reducing the cost of manual intervention and improving the level of automation.

[0015] According to some embodiments of this utility model, the mold temperature controller is connected to the medium outlet pipe, and the mold temperature controller adjusts the temperature of the temperature-regulating medium output from the medium outlet pipe to recycle the temperature-regulating medium.

[0016] The advantages of this invention are: by connecting the mold temperature controller to the medium outlet pipe, the mold temperature controller adjusts the temperature of the temperature-regulating medium output from the medium outlet pipe to recycle the temperature-regulating medium. It can be understood that the connection between the mold temperature controller and the medium outlet pipe forms a closed-loop circulation system, which can perform secondary temperature regulation on the outflowing temperature-regulating medium and reuse it. This helps to reduce the consumption cost of temperature-regulating medium, reduce energy waste, and at the same time, maintain temperature stability through circulation, thereby improving the environmental friendliness and economy of the system.

[0017] According to some embodiments of this utility model, the temperature regulating medium is set as water or oil.

[0018] The advantages are: by setting the temperature regulating medium as water or oil, it can be understood that water has advantages such as high specific heat capacity, low cost, easy availability, and no pollution. Compared with oil or special refrigerants, water is safer, easier to maintain, and conforms to the trend of green manufacturing. Oil has advantages such as high boiling point, wide temperature regulation range, and stable thermal conductivity.

[0019] According to some embodiments of the present invention, the number of clamping members is set to multiple, and a cell placement area is formed between two adjacent clamping members.

[0020] The advantages are: by setting up multiple clamping components, a cell placement area is formed between two adjacent clamping components. It can be understood that the cell placement area formed by multiple clamping components enables parallel processing of multiple cells, which significantly improves the efficiency of cell formation and capacity testing. At the same time, the modular design makes it easy to expand or reduce the capacity of the clamps to adapt to different production scale requirements, while saving equipment space.

[0021] According to some embodiments of this utility model, the number of medium inflow pipes and the number of medium outflow pipes are both provided in multiples, and one medium inflow pipe and one medium outflow pipe are respectively connected to the input end and the output end of the medium flow channel of one clamping member.

[0022] The advantages of this invention are that by having multiple media inflow pipes and multiple media outflow pipes, with each media inflow pipe and media outflow pipe connected to the input and output ends of the media flow channel of a clamping component, it can be understood that each clamping component is equipped with an independent media inflow pipe and media outflow pipe, realizing split-type temperature control, avoiding the problem of uneven temperature caused by series temperature adjustment between multiple cells, improving the stability of production quality, and at the same time, each media inflow pipe does not interfere with each other, and each media outflow pipe does not interfere with each other, so that there will be no interference or pipe pulling phenomenon when the clamping component moves.

[0023] According to some embodiments of the present invention, the clamping members are provided in multiple sets, and the number of clamping members in a set is several. The medium flow channel of the first clamping member in a set is connected to the medium inlet pipe, the medium flow channel of the last clamping member in a set is connected to the medium outlet pipe, and the medium flow channels of two adjacent clamping members in a set are connected in series through a medium flow pipe.

[0024] The advantages of this invention are: by setting multiple sets of clamping components, with a certain number of clamping components in each set, the medium flow channel of the first clamping component in each set is connected to the medium inlet pipe, the medium flow channel of the last clamping component in each set is connected to the medium outlet pipe, and the medium flow channels of two adjacent clamping components in each set are connected in series through a medium flow pipe. It can be understood that the series connection design within multiple sets of clamping components simplifies the pipeline layout, reduces the complexity of multi-channel independent control, and reduces the number of mold temperature controllers and pipe connection points while ensuring temperature uniformity, thereby reducing equipment manufacturing costs and failure rates and facilitating efficient temperature control.

[0025] According to some embodiments of the present invention, the input end and output end of the medium flow channel are disposed on the same side of the clamping member.

[0026] The advantages are: by setting the input and output ends of the medium flow channel on the same side of the clamping member, the present invention optimizes the clamping structure, reduces the bending and crossing of the medium flow pipe, facilitates quick installation and maintenance on the production line, and at the same time reduces the medium flow resistance in the medium flow channel and improves circulation efficiency.

[0027] According to some embodiments of this utility model, the medium flow tube is configured as a flexible tube.

[0028] The advantage is that by setting the medium flow pipe as a flexible hose, the flexible hose connection has vibration resistance and deformation resistance characteristics, adapts to the clamping and moving actions of the clamping components, and reduces the risk of leakage.

[0029] According to a second aspect of the present invention, a chemical formation apparatus includes a chemical formation fixture and a frame based on fluid medium temperature regulation according to a first aspect of the present invention, wherein the frame is provided with a plurality of clamping plate moving parts;

[0030] The clamping member is disposed on the moving clamping plate member or the clamping member constitutes the moving clamping plate member;

[0031] The number of clamping members is set to multiple, and a cell placement area is formed between two adjacent clamping members. The cell placement area is used to place the cell. Two adjacent clamping plate moving members move closer to drive the two clamping members to clamp the cell in the cell placement area.

[0032] The formation apparatus according to the embodiments of the present invention has at least the following beneficial effects:

[0033] 1. This utility model, by setting a medium flow channel in the clamping component, inputs a temperature-regulating medium into the medium flow channel through a medium inlet pipe and outputs the temperature-regulating medium from the medium flow channel through a medium outlet pipe. This allows the temperature-regulating medium to flow within the medium flow channel. By inputting temperature-regulating media of different temperatures into the medium flow channel, bidirectional temperature regulation of the clamping component (heating and cooling) can be achieved. Furthermore, this enables bidirectional temperature regulation of the battery cell (heating and cooling) by the clamping component. Compared to existing heating tubes or heating plates that can only heat, this solution, through the flowing temperature-regulating medium, can control the battery cell temperature below or above room temperature, improving the temperature regulation range and significantly enhancing the temperature adaptability of the formation device, meeting the differentiated needs of different battery cell manufacturing processes.

[0045] The following description, in conjunction with the accompanying drawings, describes a chemical formation fixture and device based on fluid medium temperature regulation according to an embodiment of the present invention.

[0046] This utility model aims to provide embodiments of a chemical formation fixture and chemical formation device based on fluid medium temperature control.

[0047] Reference Figure 1 and Figure 2 In this embodiment, the formation apparatus mainly includes a formation fixture based on fluid medium temperature control and a frame 140. The frame 140 is provided with multiple clamping plate moving parts. Clamping parts 100 are disposed on the clamping plate moving parts or the clamping parts 100 constitute the clamping plate moving parts. The number of clamping parts 100 is multiple, and a cell placement area is formed between two adjacent clamping parts 100. The cell placement area is used to place cell parts. Two adjacent clamping plate moving parts move closer to each other to drive the two clamping parts 100 to clamp the cell parts in the cell placement area. Thus, the formation apparatus can process multiple cell parts at the same time, thereby improving production efficiency.

[0048] Furthermore, the formation device is also equipped with a driving component, which is used to drive the clamping plate moving component to move so that multiple clamping plate moving components can approach and squeeze the battery cell located on the adjacent clamping plate moving component.

[0049] Reference Figure 3 The chemical formation fixture based on fluid medium temperature regulation according to this utility model embodiment includes a clamping member 100, a medium inflow pipe 110 and a medium outflow pipe 120.

[0050] The clamping member 100 is used to clamp the battery cell and has a medium flow channel for the flow of temperature regulating medium.

[0051] The medium inlet pipe 110 is connected to the input end of the medium flow channel and is used to input the temperature regulating medium into the medium flow channel.

[0052] The medium outlet pipe 120 is connected to the output end of the medium flow channel and is used to output the temperature-regulating medium from the medium flow channel.

[0053] This embodiment provides a medium flow channel in the clamping member 100. A temperature-regulating medium is input into the medium flow channel via the medium inlet pipe 110, and then output via the medium outlet pipe 120. This allows the temperature-regulating medium to flow within the medium flow channel. By inputting temperature-regulating media of different temperatures into the medium flow channel, bidirectional temperature regulation of heating and cooling of the clamping member 100 can be achieved. Consequently, bidirectional temperature regulation of heating and cooling of the battery cell by the clamping member 100 can be achieved. Compared to existing heating tubes or heating plates that can only heat, this solution can control the battery cell temperature below or above room temperature through the flowing temperature-regulating medium, improving the temperature regulation range and significantly enhancing the temperature adaptability of the formation device, thus meeting the differentiated needs of different battery cell manufacturing processes.

[0054] Specifically, the temperature regulating medium is set to water or oil.

[0055] It is understandable that water is chosen as the temperature control medium because it has advantages such as high specific heat capacity, low cost, easy availability, and no pollution. Compared with oil or special refrigerants, water is safer, easier to maintain, and conforms to the trend of green manufacturing. Oil is chosen as the temperature control medium because it has advantages such as high boiling point, wide temperature regulation range, and stable thermal conductivity.

[0056] Specifically, when the temperature regulating medium is set to oil, heat transfer oil, dimethyl silicone oil, etc. can be selected.

[0057] In some specific embodiments, the formation fixture based on fluid medium temperature control also includes a mold temperature controller, which is connected to the medium inflow pipe 110 and is used to adjust the temperature of the temperature-regulating medium in the input medium flow channel.

[0058] Understandably, by connecting the mold temperature controller to the medium inflow pipe 110, precise control of the input temperature of the temperature-regulating medium is achieved. The mold temperature controller can actively adjust the temperature of the temperature-regulating medium according to demand, such as cooling or heating, further enhancing the temperature regulation range and efficiency, while reducing the cost of manual intervention and improving the level of automation.

[0059] Furthermore, the mold temperature controller is connected to the medium outlet pipe 120, and the mold temperature controller adjusts the temperature of the temperature-regulating medium output from the medium outlet pipe 120 to recycle the temperature-regulating medium.

[0060] Understandably, the connection between the mold temperature controller and the medium outflow pipe 120 forms a closed-loop circulation system, which can perform secondary temperature regulation on the outflowing temperature-regulating medium and reuse it. This helps to reduce the consumption cost of the temperature-regulating medium, reduce energy waste, and at the same time maintain temperature stability through circulation, thereby improving the environmental friendliness and economy of the system.

[0061] In some specific embodiments, the number of clamping members 100 is set to multiple, and a cell placement area is formed between two adjacent clamping members 100.

[0062] It is understandable that the battery cell placement area formed by the multiple clamping components 100 enables parallel processing of multiple battery cells, significantly improving the efficiency of cell formation and capacity measurement. At the same time, the modular design facilitates the expansion or reduction of the clamping capacity to adapt to different production scale requirements, while saving equipment space.

[0063] Specifically, multiple clamping members 100 are arranged side by side, and the clamping members 100 can move along the arrangement direction of the multiple clamping members 100, thereby facilitating the movement of the multiple clamping members 100 to clamp or release the battery cell.

[0064] Furthermore, there are multiple media inflow pipes 110 and multiple media outflow pipes 120. One media inflow pipe 110 and one media outflow pipe 120 are respectively connected to the input end and the output end of the media flow channel of a clamping member 100.

[0065] Understandably, each clamping component 100 is equipped with an independent medium inflow pipe 110 and a medium outflow pipe 120 to achieve split temperature control, avoid the problem of uneven temperature caused by series temperature adjustment between multiple cells, improve the stability of production quality, and at the same time, each medium inflow pipe 110 does not interfere with each other, and each medium outflow pipe 120 does not interfere with each other, so that there will be no interference or pipe pulling phenomenon when the clamping component 100 moves.

[0066] In other embodiments, multiple sets of clamping members 100 are provided, and the number of clamping members 100 in a set is set to a certain number. The medium flow channel of the first clamping member 100 in a set of clamping members 100 is connected to the medium inlet pipe 110, the medium flow channel of the last clamping member 100 in a set of clamping members 100 is connected to the medium outlet pipe 120, and the medium flow channels of two adjacent clamping members 100 in a set of clamping members 100 are connected in series through the medium flow pipe 130.

[0067] Understandably, the series connection design of multiple clamping components 100 simplifies the pipeline layout and reduces the complexity of independent control of multiple channels. By connecting the components in series, the number of mold temperature controllers and pipeline connection points can be reduced while ensuring temperature uniformity, thereby reducing equipment manufacturing costs and failure rates and facilitating efficient temperature control.

[0068] In some specific embodiments, in order to reduce the bends and intersections of the medium flow pipe 130, facilitate quick installation and maintenance on the production line, and at the same time reduce the medium flow resistance in the medium flow channel and improve circulation efficiency, the input end and output end of the medium flow channel are set on the same side of the clamping member 100.

[0069] In some specific embodiments, the medium flow tube 130 is configured as a flexible tube.

[0070] Understandably, the hose connection has vibration resistance and deformation resistance characteristics, adapts to the clamping and moving action of the clamping component 100, and reduces the risk of leakage.
