Description

Technical Field

[0001] This application belongs to the field of battery testing technology, and in particular relates to a formation pressure fixture. Background Technology

[0002] Power pouch batteries are one of the main batteries used in new energy vehicles. In the later stages of production, power pouch batteries need to undergo high-temperature formation to activate the cells. In the formation process, the cells need to be charged and discharged by a drive box. In the existing process, the cells are placed between a pair of plates in a high-temperature fixture machine. The plates apply high temperature and pressure to the cells, while the contact plate probes clamp the battery tabs to activate the cells through a charge and discharge formation process.

[0003] In existing fixture forming equipment, the number of layers in each fixture is generally no more than 40. If the number of layers is too large, the pressure screw and the layer support guide shaft need to be lengthened. At this time, the screw and the support guide shaft are prone to bending, which leads to screw deformation, increases the pressure difference between the front and rear, and reduces the uniformity of the fixture pressure.

[0004] To prevent deformation of the lead screw and support guide shaft, existing designs use a support in the middle of the fixture forming equipment. This fixed support position makes it difficult to apply air pressure. It should be noted that air pressure here refers to situations where some positions between the layers do not have cells to be pressurized. Utility Model Content

The support guide shaft is located on both sides of the chemical formation pressurizing fixture in the Y direction and extends along the X direction. The support structure is located in the middle of the chemical formation pressurizing fixture in the X direction and includes a movable guide shaft support plate.

[0010] In an optional embodiment of this application, the support structure further includes a lead screw support plate, which is connected to the bracket assemblies on both sides and has lead screw through holes to allow the lead screw to pass through.

[0011] In an optional embodiment of this application, the chemical formation pressure fixture further includes a lead screw, a pressure module, and multiple shelf assemblies; the lead screw is located on both sides of the chemical formation pressure fixture in the Y direction and extends along the X direction, and is further outward relative to the support guide shaft; multiple shelf assemblies are spaced apart along the X direction and slidably connected to the support guide shafts on both sides, and shelf assemblies are arranged on both sides of the support structure in the X direction; the pressure module is connected to the lead screws on both sides and is used to move the shelf assemblies closer to or further away from the support structure, so as to cooperate with the support structure to apply X-direction pressure to the shelf assemblies.

[0012] In an optional embodiment of this application, the pressurizing module includes a front push plate assembly, a rear pressure plate assembly, and a pressurizing power module; the front push plate assembly and the rear pressure plate assembly are respectively connected to the two ends of the lead screws on both sides in the X direction, and the pressurizing power module is connected to the lead screws on both sides and is used to drive the lead screws on both sides to rotate, so that the front push plate assembly drives the shelf assembly between the front push plate assembly and the support structure to move toward or away from the support structure, and so that the rear pressure plate assembly drives the shelf assembly between the rear pressure plate assembly and the support structure to move toward or away from the support structure.

[0013] In an optional embodiment of this application, the pressurizing module further includes a pressure detection component. The pressure detection component is connected to the support guide shafts on both sides and is located between the rear pressure plate assembly and the shelf assembly on the X-direction end side.

[0014] In an optional embodiment of this application, the shelf assembly includes a shelf, in which flow channels are formed and a connector communicating with the flow channels is provided on the bottom side.

[0015] In an optional embodiment of this application, the shelf assembly includes airbags located on both sides of the shelf assembly in the Y direction and configured to inflate during pressurization.

[0016] In summary, the formation pressure fixture provided in this application has at least the following beneficial effects:

[0017] The chemical formation pressurizing fixture has a support structure at the center in the X direction to provide support in the middle. Specifically, the movable guide shaft support plate is located at the center of the support guide shaft, which can provide support for the support guide shaft, ensure that the support guide shaft is not easily deformed, and ensure uniform pressurization.

[0018] Furthermore, the movable guide shaft support plate can move along the X direction. When there is no cell to be pressurized on one side of the movable guide shaft support plate in the X direction, there is an empty pressure situation. During pressurization, the missing position is missing the thickness of the cell. Since the movable guide shaft support plate can move along the X direction, it can compensate for the missing cell thickness at the missing position. In this way, the formation pressurization fixture can be used in the empty pressure situation and has higher versatility. Attached Figure Description

[0031] In this application, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In the description of this specification, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0033] In the description of this application, "X direction", "Y direction" and "Z direction" are determined based on the orientation of the formation pressure fixture. Among them, "X direction" is longitudinal, which is also the length direction; "Y direction" is transverse, which is also the width direction; and "Z direction" is vertical, which is also the up and down direction.

[0034] Figure 1 This is a schematic diagram of a chemical formation pressure fixture provided according to one embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the chemical formation pressure fixture from another perspective. Figure 3 for Figure 1 A schematic diagram of the central support structure 20. Please refer to [link / reference]. Figures 1 to 3 The chemical forming pressure fixture includes a support guide shaft 10 and a support structure 20.

[0035] The support guide shaft 10 is located on both sides of the formation pressurization fixture in the Y direction and extends along the X direction. The support structure 20 is located in the middle of the formation pressurization fixture in the X direction and includes a movable guide shaft support plate 21. The movable guide shaft support plate 21 is arranged along the Y direction and has guide shaft through holes H1 on both sides of the Y direction to allow the support guide shaft 10 to pass through. The movable guide shaft support plate 21 is configured to be movable along the X direction.

[0036] In this embodiment, the forming pressure fixture has a support structure 20 at the middle position in the X direction to provide support in the middle. Specifically, the movable guide shaft support plate 21 is located at the middle position of the support guide shaft 10, which can provide support for the support guide shaft 10, ensure that the support guide shaft 10 is not easily deformed, and ensure uniform pressure.

[0037] Furthermore, the movable guide shaft support plate 21 can move along the X direction. When there is no cell to be pressurized on one side of the movable guide shaft support plate 21 in the X direction, there is an empty pressure situation. During pressurization, the missing position is missing the thickness of the cell. Since the movable guide shaft support plate 21 can move along the X direction, it can compensate for the missing cell thickness at the missing position. In this way, the formation pressurization fixture can be used in the empty pressure situation and has higher versatility.

[0038] In the illustrated embodiment, there are four supporting guide shafts 10, and two supporting guide shafts 10 on one side of the Y direction. Correspondingly, there are four guide shaft through holes H1, and two guide shaft through holes H1 on one side of the Y direction. It can be understood that the number of guide shaft through holes H1 can be determined based on the number of supporting guide shafts 10.

[0039] In a further optional embodiment, the movable guide shaft support plate 21 includes a guide shaft support plate 211 and support rollers 212. The guide shaft through hole H1 is located on both sides of the guide shaft support plate 211 in the Y direction, and the support rollers 212 are connected to both sides of the guide shaft support plate 211 in the Y direction and can roll in the X direction.

[0040] In this embodiment, the movable guide shaft support plate 21 is composed of a guide shaft support plate 211 and a support roller 212. The support roller 212 is installed on both sides of the guide shaft support plate 211 in the Y direction and located below the guide shaft support plate 211. The support roller 212 can roll in the X direction, so the guide shaft support plate 211 can also move in the X direction, that is, move along the support guide shaft 10.

[0041] In practical applications, the guide shaft through hole H1 is located on both sides of the guide shaft support plate 211 in the Y direction and is clearance-fitted with the support guide shafts 10 on both sides to ensure that the guide shaft support plate 211 can move in the X direction.

[0042] Figure 4 for Figure 3 A schematic diagram of the support structure 20 from another perspective. Please refer to... Figure 3 and Figure 4 In a further optional embodiment, the support structure 20 includes a bracket assembly 22, which is disposed below the Y-direction sides of the movable guide shaft support plate 21 and connected to the support rollers 212.

[0043] In this embodiment, bracket assemblies 22 are arranged on both sides of the movable guide shaft support plate 21 in the Y direction. The bracket assemblies 22 on both sides of the Y direction provide support so that the movable guide shaft support plate 21 is at a suitable height so that the height of the guide shaft support plate 211 is adapted to the height of the support guide shaft 10.

[0044] Furthermore, the support assembly 22 on one side is supported below the support roller 212 on the same side, meaning that the support roller 212 can move relative to the support assembly 22 in the X direction.

[0045] In one embodiment, the bracket assembly 22 can be finely adjusted in height. For example, the mounting holes on the bracket assembly 22 are elongated holes arranged along the Z direction, which can be finely adjusted to ensure that the height of the guide shaft support plate 211 is appropriate.

[0046] In a further optional embodiment, the bracket assembly 22 includes a fixed mounting bracket 221 and a support base plate 222. The support base plate 222 extends along the X direction and is connected to the top side of the fixed mounting bracket 221, and the support rollers 212 are capable of rolling along the support base plate 222.

[0047] In this embodiment, the bracket assembly 22 includes at least a fixed mounting bracket 221 and a support base plate 222. The fixed mounting bracket 221 provides support, and the support base plate 222 is a long strip plate that extends along the X direction. In conjunction with the support guide shaft 10 extending in the X direction, the support roller 212 has only the X-direction of freedom of movement.

[0048] In a further optional embodiment, the support structure 20 also includes a lead screw support plate 23, which has a lead screw through hole H2 to allow the lead screw 30 to pass through.

[0049] In this embodiment, the support structure 20 also includes a lead screw support plate 23 with a lead screw through hole H2 on the lead screw support plate 23. In specific applications, the lead screw support plate 23 is fixedly mounted on the fixed mounting bracket 221 in the bracket assembly 22.

[0050] The lead screw support plate 23 in the support structure 20 located in the middle of the X direction can provide support for the middle of the lead screw 30 in the X direction to ensure that the lead screw 30 is not easily deformed.

[0051] Please see Figure 1 and Figure 2 In some optional embodiments, the formation pressure fixture further includes a lead screw 30, a pressure module 40, and multiple shelf assemblies 50. The lead screw 30 is located on both sides of the formation pressure fixture in the Y direction and extends along the X direction, and is further outward relative to the support guide shaft 10. Multiple shelf assemblies 50 are spaced apart along the X direction and slidably connected to the support guide shaft 10 on both sides, and shelf assemblies 50 are arranged on both sides of the support structure 20 in the X direction.

[0052] The pressure module 40 is connected to the lead screws 30 on both sides and is used to move the shelf assembly 50 closer to or away from the support structure 20, so as to cooperate with the support structure 20 to apply X-direction pressure to the shelf assembly 50.

[0053] In this embodiment, the formation pressure fixture further includes a pressure module 40 and multiple shelf assemblies 50. The pressure module 40 cooperates with lead screws 30 on both sides in the Y direction. The multiple shelf assemblies 50 are all mounted on the support guide shafts 10 on both sides and can slide along the support guide shafts 10, thus having a degree of freedom of movement in the X direction. In specific applications, the shelf assemblies 50 are provided with through holes on both sides in the Y direction that are interference-fitted with the support guide shafts 10, so that the shelf assemblies 50 can move along the support guide shafts 10.

[0054] Multiple shelf assemblies 50 are arranged at intervals in the X direction, and a cell to be pressurized can be placed between any two adjacent shelf assemblies 50. The pressurization module 40, together with the lead screws 30 on both sides, can move these shelf assemblies 50 closer to or further away from the central support structure 20.

[0055] It should be understood that when these shelf assemblies 50 move closer to the central support structure 20, any two adjacent shelf assemblies 50 move closer to each other to clamp the battery cell located between them, i.e., to apply X-direction pressure to the battery cell. When these shelf assemblies 50 move away from the central support structure 20, any two adjacent shelf assemblies 50 move away from each other, thereby releasing the battery cell located between them.

[0056] It should be noted that most existing clamps use unilateral movement to pressurize the battery cell, which leads to high friction in the later stages of movement and excessive pressure deviation at both ends in the X direction.

[0057] The formation pressurization fixture provided in this solution allows the cells located on both sides of the support structure 20 in the X direction to move closer to or further away from the support structure 20 (at the middle position), meaning that pressure is applied from both sides of the X direction towards the middle. Compared to the existing single-sided pressurization solution, this reduces the impact of friction on pressurization and avoids excessive end pressure deviation.

[0058] In the illustrated embodiment, there are 4 lead screws 30, 2 lead screws 30 on the Y-axis single side, 2 lead screw support plates 23 on the Y-axis single side bracket assembly 22, and 2 through holes on the Y-axis single side of the shelf assembly 50 that are interference-fitted with the support guide shaft 10.

[0059] In a further optional embodiment, the pressurizing module 40 includes a front push plate assembly 41, a rear pressure plate assembly 42, and a pressurizing power module 43. The front push plate assembly 41 and the rear pressure plate assembly 42 are respectively connected to the X-axis ends of the lead screws 30 on both sides. The pressurizing power module 43 is connected to the lead screws 30 on both sides and is used to drive the lead screws 30 on both sides to rotate, so that the front push plate assembly 41 drives the shelf assembly 50 between the front push plate assembly 41 and the support structure 20 to move toward or away from the support structure 20, and so that the rear pressure plate assembly 42 drives the shelf assembly 50 between the rear pressure plate assembly 42 and the support structure 20 to move toward or away from the support structure 20.

[0060] In this embodiment, the pressurizing module 40 includes at least a front push plate assembly 41, a rear pressure plate assembly 42, and a pressurizing power module 43. The front push plate assembly 41 is connected to the lead screws 30 on both sides and is located at one end in the X direction, and the rear pressure plate assembly 42 is connected to the lead screws 30 on both sides and is located at the other end in the X direction.

[0061] The pressurizing power module 43 can drive the lead screws 30 on both sides to rotate synchronously, so that the front push plate assembly 41 and the rear pressure plate assembly 42 at both ends move closer to or further away from the central support structure 20. Specifically, the front push plate assembly 41 and the rear pressure plate assembly 42 at both ends move closer to or further away from each other.

[0062] As the front push plate assembly 41 moves closer to or further away from the central support structure 20, the front push plate assembly 41 can drive the layer plate assemblies 50 located between the front push plate assembly 41 and the support structure 20 to move closer to or further away from the support structure 20. When moving closer to the support structure 20, the cell is pressurized in the X direction, and when moving away from the support structure 20, the pressure is released from the cell.

[0063] As the rear pressure plate assembly 42 approaches or moves away from the central support structure 20, the rear pressure plate assembly 42 can drive the layer assemblies 50 located between the rear pressure plate assembly 42 and the support structure 20 to approach or move away from the support structure 20 together. When approaching the support structure 20, the cell is pressurized in the X direction, and when moving away from the support structure 20, the pressure is released from the cell.

[0064] In practical applications, the lead screw 30 is a bidirectional lead screw, which means it has two screw segments with two directions of rotation. Specifically, one segment of the bidirectional lead screw is a left-handed lead screw segment, and the other segment is a right-handed lead screw segment. In this embodiment, the lead screw segment on the X-direction side of the support structure 20 is a left-handed lead screw segment, and the lead screw segment on the other X-direction side of the support structure 20 is a right-handed lead screw segment. In this way, during the rotation of the lead screw 30, the front push plate assembly 41 and the rear pressure plate assembly 42 can synchronously approach or move away from each other.

[0065] In addition, the pressurized power module 43 is located at one end in the X direction and can be a combination of a motor and a transmission mechanism. The transmission mechanism can be a synchronous belt, a gear set, etc., which will not be listed here.

[0066] In a further optional embodiment, the pressurizing module 40 further includes a pressure detection component 44, which is connected to the support guide shafts 10 on both sides and located between the rear pressure plate assembly 42 and the shelf assembly 50 on the X-direction end side. The pressure detection component 44 is configured to be driven by the rear pressure plate assembly 42 to move along the X-direction.

[0067] In this embodiment, the pressurizing module 40 also includes a pressure detection component 44 capable of detecting X-direction pressure. During the pressurization detection process, the pressure detection component 44 can move along the X-direction together with the rear pressure plate assembly 42 and be clamped between the rear pressure plate assembly 42 and the layer plate assembly 50 on the X-direction end side. In this way, the pressure detection component 44 will bear X-direction pressure to achieve X-direction pressure detection.

[0068] In specific applications, the pressure detection component 44 is equipped with a pressure sensor and is a plate that is slidably connected to the support guide shafts 10 on both sides.

[0069] Figure 5 for Figure 1 A schematic diagram of the middle layer assembly 50. Please refer to [link / reference]. Figure 5 In some alternative embodiments, the shelf assembly 50 includes a shelf 51, in which flow channels are formed and a connector 52 communicating with the flow channels is provided on the bottom side.

[0070] In this embodiment, the shelf assembly 50 includes at least a shelf 51, the shelf 51 has a flow channel inside, and a connector 52 is installed on the bottom side of the shelf 51 to connect to an external liquid passage.

[0071] In practical applications, the shelf 51 is connected to an external hot water pipe through the connector 52 so that hot water can flow through the internal channels of the shelf 51, thereby raising the temperature of the shelf 51 and heating the battery cells sandwiched between the shelf assembly 50 to maintain the high temperature and high pressure test conditions. Replacing the existing electric heating with hot water heating can effectively reduce energy consumption.

[0072] In a further optional embodiment, the shelf assembly 50 includes airbags 53 located on both sides of the shelf assembly 50 in the Y direction and configured to inflate during pressurization.

[0073] In this embodiment, airbags 53 are arranged on both sides of the Y-direction of the layer assembly 50, and the airbags 53 expand during inflation. In specific applications, the airbags 53 are located at the positions of the electrode tabs of the battery cell, and expand during pressurization to press the electrode tabs together.

[0074] It should be noted that with existing fixtures, if there is no battery cell between two shelves, a dummy battery cell of the same size and specifications as the battery cell to be tested needs to be used as a substitute to prevent damage to the shelves due to stress. That is, existing fixtures use dummy batteries to cope with air pressure conditions. However, in this embodiment, due to the presence of airbags 53, air pressure can be achieved without using dummy batteries during pressurization, reducing the use of dummy batteries. The airbags 53 on two adjacent shelf assemblies 50 at the air pressure position can be connected to each other.

[0075] Furthermore, the description in this application that mentions no battery cells between the shelves mainly refers to the absence of battery cells between some shelves, not to the absence of battery cells between all shelves. In other words, the "air-pressurized" scenario refers to the absence of battery cells between shelves in a few scattered locations.

[0076] Furthermore, since the chemical formation pressurization fixture has a support structure 20 in the middle, it is more compatible with pneumatic conditions. Therefore, the number of shelf assemblies 50 can be appropriately increased. In this embodiment, the number of shelf assemblies 50 is not less than 40.

[0077] In summary, this formation pressurizing fixture offers several advantages: First, the addition of a support in the middle of the support guide shaft 10 reduces deformation, minimizes pressure deviation, and improves the uniformity of force distribution on the battery cells. Second, the addition of a support in the middle of the lead screw 30 reduces deformation and improves force distribution on the lead screw 30. Third, the guide shaft support plate 211 can move in the X direction, and in conjunction with the air bladder 53 on the shelf assembly 50, it can be compatible with compressed air, simplifying loading and unloading methods and saving costs. Fourth, bidirectional pressurization increases the number of battery cells formed in a single operation, reduces clamping time, and improves work efficiency. Fifth, the shelf assembly 50 uses hot water heating, reducing energy consumption. Of course, the advantages of this formation pressurizing fixture are not limited to these.

[0078] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
