Technical Field

[0001] This utility model relates to the field of pressure clamp technology, specifically to a temperature control layer structure. Background Technology

[0002] With the development of high-density electronic devices and precision industrial equipment, the requirements for working temperature environment are becoming increasingly stringent. Traditional single heat dissipation or heating modes are insufficient to meet the dual demands of temperature control accuracy and efficiency under complex working conditions.

[0003] In the field of solid-state battery manufacturing, the layered assembly and reaction processes of the cells impose stringent standards on temperature uniformity, rapid response, and precise regulation. During the production process of solid-state batteries, the complex chemical reactions and physical assembly steps are greatly affected by temperature fluctuations. Localized overheating or underheating can lead to battery performance degradation and safety hazards. Similarly, in high-performance computing devices, chips and peripheral components generate a large amount of heat during high-load operations. However, low-temperature startup or special scenarios require preheating to ensure performance. Traditional temperature control methods often fail to address both aspects, resulting in uneven heat dissipation or slow heating, and are difficult to adapt to limited space and complex layouts.

Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] like Figures 1-12 As shown, this utility model describes a temperature control layer structure.

[0032] Solid-state batteries, with their high energy density and safety, are considered strong candidates for next-generation energy storage technology. However, their industrialization still faces core challenges such as poor solid-solid interface contact and lithium dendrite growth. Research has confirmed that ensuring uniform and dynamically controllable pressure during the charging and discharging process of solid-state batteries is a key technical means to improve interface contact stability and suppress lithium dendrite growth. This invention, through an innovative configuration design of existing battery clamps and the integration of a high-precision pressure servo control system, effectively solves the technical problems of uniformity control and dynamic response speed optimization during pressure application. The pressure clamp equipment used in this invention can significantly improve the interface stability of solid-state batteries, extend battery cycle life, and provide key process equipment support for the research and development and large-scale production of solid-state batteries.

[0033] This utility model presents a temperature-controlled layer structure specifically designed for the cell stacking and pressure application stages in solid-state battery manufacturing. Its purpose is to apply stable, uniform, and controllable high pressure to the cells, ensuring the compactness and stability of the internal structure of the solid-state battery, thereby improving battery performance and quality. This high-pressure clamping machine adopts an integrated design of power supply, pressure clamps, and frame, offering advantages such as compact structure, small footprint, convenient maintenance, and high charge / discharge efficiency, flexibly adaptable to laboratory R&D needs. Furthermore, this high-pressure clamping machine supports production line-level expansion applications. By deploying multiple machines side-by-side, combined with overhead cranes and robotic arms to achieve automatic battery loading and unloading, a highly automated solid-state battery mass production line can be built. This fully meets the charge / discharge requirements of various pouch batteries in processes such as pressure formation, pressure capacity testing, and pressure OCV / DCIR testing, accelerating the industrialization of solid-state batteries.

[0034] Example 1

[0035] like Figures 1-2 As shown, a high-pressure clamping machine includes: a high-pressure clamping body 1, which is used to apply pressure to solid-state batteries for encapsulation; a second frame mechanism 9, on which the high-pressure clamping body 1 is mounted; a first frame mechanism 8, which is mounted on the second frame mechanism 9 and adapted to the second frame mechanism 9; a cavity is provided inside the second frame mechanism 9 for placing the charging and discharging power supply 92, which is electrically connected to the high-pressure clamping body 1; and a loading and unloading platform; the loading and unloading platform is placed near the pressure clamping platform for manual loading and unloading.

[0036] Specifically, the high-pressure clamp body 1, as the core of the high-pressure clamping machine, is responsible for applying uniform and dynamically controllable pressure to the battery. Through a precise pressure control system, it can simulate pressure environments under different working conditions, ensuring the stability and safety of the battery during charging and discharging.

[0037] In one embodiment, the bottom of the second frame mechanism 9 is equipped with a moving device 91 to facilitate the handling and positioning of the equipment. It can also be fixed to the ground by welding or bolting to ensure equipment stability. The moving device can be rollers or forklift mounting holes, etc.

[0038] In one embodiment, the surface of the loading and unloading platform is covered with an anti-slip mat to ensure the stability of the operator during operation. The anti-slip mat is made of rubber material with an anti-slip texture, which can effectively increase the friction between the operator and the platform, preventing slips and other safety accidents.

[0039] In a preferred embodiment, a hazardous gas monitoring system is integrated within the first frame structure 8. The hazardous gas monitoring system includes a gas concentration sensor and an emergency response module. The gas concentration sensor is installed on the inner wall of the first frame structure to detect the concentration of hazardous substances. The emergency response module is used to activate an emergency ventilation device when the concentration of hazardous substances exceeds a preset threshold. When the concentration exceeds the warning limit, the emergency response module immediately sends a signal to the control system to trigger the activation of the emergency ventilation device.

[0040] In a preferred embodiment, the emergency ventilation device includes a plurality of emergency ventilation outlets, which are disposed at the top of the first frame structure 8. The emergency ventilation outlets are activated by electric or manual control to reduce the concentration of harmful substances.

[0041] Specifically, the top of the first frame mechanism 8 is equipped with several emergency exhaust vents 81. When the detection device detects that the concentration of hazardous substances in the pressure fixture platform exceeds the warning limit, it can automatically activate the emergency exhaust vents 81 to reduce the concentration of hazardous substances and ensure production safety. The emergency exhaust vents 81 are controlled electrically or manually. When the concentration of hazardous substances is detected to exceed the warning limit, the emergency exhaust vents 81 can be activated automatically or manually to reduce the concentration of hazardous substances. The emergency exhaust vents 81 are reasonably designed and can effectively remove hazardous gases.

[0042] In a preferred embodiment, the first frame mechanism 8 is provided with a protective device 83, which includes a safety door and a safety door lock. The safety door lock is connected to a safety module and is used to detect abnormalities in the high-pressure clamping machine and promptly alarm and stop the machine, which can effectively prevent safety hazards.

[0043] In a preferred embodiment, the first frame mechanism 8 is provided with a display device 82 for displaying relevant parameters of the pressure clamp platform, as well as whether materials are lacking, etc. The display device 82 can be a display screen or an industrial control computer, etc.

[0044] In a preferred embodiment, such as Figure 3 As shown, the overhead crane track 10 extends along the length of several large pressure clamping machines placed side by side, and is installed on the inner top surface of the first frame mechanism 8 of the several large pressure clamping machines in a continuous transverse manner; an overhead crane robot 101 is installed on the overhead crane track 10 to realize the automatic loading and unloading of the large pressure clamping body 1, thereby constructing a highly automated solid-state battery mass production line, meeting the needs of large-scale production, and solving the problem of slow manual loading and unloading speed.

[0045] Specifically, the overhead crane track 10 is rigidly fixed directly to the inner top surface of the first frame mechanism 8 of each piece of equipment, ensuring that the track has sufficient load-bearing rigidity and stability. The track is erected at a certain height above the equipment operating area (such as the pressure clamp body, loading and unloading station), creating an unobstructed high-altitude movement channel for the overhead crane robot 101 that covers all parallel equipment. The track is directly integrated into the top of the first frame, eliminating the need for additional ground or inter-equipment passage space, thus solving the spatial bottleneck of material transfer when multiple pieces of equipment are arranged side by side. A continuous track spans all equipment, allowing a single overhead crane robot to serve an entire row of clamping machines, achieving efficient material flow in high-density equipment layouts. The overhead crane robot 101 can move freely and precisely on the track to directly above any clamping machine, performing gripping, lifting, horizontal transfer, lowering, and placement actions of the large pressure clamp body 1 (or battery unit), completely replacing manual loading and unloading. The robotic arm can quickly switch between adjacent machines according to the production rhythm, or perform parallel tasks on multiple machines (such as one machine picking up material while another is unloading it), significantly improving overall production efficiency. The overhead crane track 10 is continuously fixed to the top of the first frame mechanism of each of the parallel-arranged high-pressure clamping machines, creating an elevated, continuous, and highly rigid automated logistics channel. This design fully utilizes the structural space of the equipment body, achieving a high degree of automation, high efficiency, and inherent safety in material handling between multiple machines. It is a key innovative layout for achieving unmanned / reduced manpower loading and unloading in compact production lines.

[0046] Example 2

[0047] In one embodiment, such as Figure 4As shown, a high-pressure clamp body 1 includes a support frame, which comprises several tie rod assemblies 11, a front end plate 12, a push plate 14, and a rear end plate 13; the front end plate 12 is connected to the rear end plate 13 via the tie rod assemblies 11; a pressurization power assembly system 2 passes through the front end plate 12 and is connected to a correction assembly 3, which is mounted on the outside of the push plate 14; and a battery support system 4, the first end of which is connected to the push plate 14 via a first pressure detection device 43. Inside, the tail end of the battery carrying system 4 is connected to the rear end plate 13 via a second pressure detection device 44; the guide post 16 passes through the front end plate 12, linear bearing 141, push plate 14, battery carrying system 4 and rear end plate 13 in sequence to form a coaxial guide structure, and the axis of the guide post 16 is in the same plane as the output axis of the pressurized powertrain system 2; the distance adjustment system 5 has one end fixed to the left side of the push plate 14 and the other end fixed to the inside of the rear end plate 13.

[0048] Specifically, the front end plate 12 and the rear end plate 13 are connected by four tie rod assemblies 11 to form an integral frame structure. The connection uses a double-nut locking structure, and the expected force of the nuts is calculated and controlled to ensure that the front end plate 12 and the rear end plate 13 will not shift or deform during the stress process, providing a stable installation and support platform for the internal system, components, and solid-state battery of the pressure clamp device. The linear bearing 141 is fixed to the push plate with screws, and the guide post 16 passes through the linear bearing 141 and the push plate 14 in sequence. At the same time, the high-pressure clamp is equipped with double guide posts, which are set inside the tie rod assembly 11 and are parallel to the tie rod assembly 11 and symmetrically arranged. The central axis of the guide post 16 and the output axis of the powertrain are in the same plane, which solves the problem of frame deformation caused by off-center load under high pressure conditions.

[0049] In a preferred embodiment, the front end plate 12 and the rear end plate 13 are provided with stepped through holes adapted to the pull rod assembly 11; the pull rod assembly 11 passes through the stepped through holes of the front end plate 12 and the rear end plate 13 in sequence; after passing through the front end plate 12 and the rear end plate 13, the pull rod assembly 11 is fixed to the front end plate 12 and the rear end plate 13 respectively by a double nut top locking structure; the tensioning and positioning mechanism includes a tensioning sleeve 15 disposed between the front end plate 12 and the guide post 16 and a tensioning sleeve 15 disposed between the rear end plate 13 and the guide post 16; the inner hole of the tensioning sleeve 15 is provided with an interference fit with the outer surface of the guide post 16; one end of the guide post 16 is connected to the front end plate 12 through the tensioning sleeve 15, and the other end of the guide post 16 is connected to the rear end plate 13 through the tensioning sleeve 15.

[0050] Specifically, the stepped through holes of the front plate 12 and the rear plate 13 accommodate the threaded section of the tie rod assembly 11 in their large-diameter sections, while the small-diameter sections provide axial restraint, forming a dual function of "positioning + connection". A double-nut counter-rotating structure (such as two M16 nuts screwed in opposite directions) is adopted, utilizing the friction between the threads to eliminate the risk of loosening caused by vibration. This ensures that the tie rod assembly 11 will not experience axial displacement or loosening when subjected to the tension and pressure generated during the operation of the high-pressure fixture, guaranteeing the structural stability and reliability of the entire device and providing a stable processing environment for solid-state battery production. The inner hole of the expansion sleeve 15 and the guide post 16 adopt an H7 / S6 grade interference fit, generating radial pressure through hydraulic expansion or mechanical pressing to form a keyless connection. This design achieves zero-backlash transmission, ensuring the axial / radial positioning accuracy of the guide post 16. The conical structure of the expansion sleeve 15 allows for fine-tuning in the loosened state. When shelf misalignment needs to be calibrated, the tension force is released using hydraulic tools. The guide post 16 can automatically eliminate the gap after being re-tightened by disassembling the tension positioning mechanism. Disassembling the tension positioning mechanism is necessary to replace worn guide sleeves and other components; however, this disassembly is not required when adapting to batteries of different sizes. Furthermore, this design facilitates replacement of shelves worn due to frequent expansion and contraction during long-term use, improving the system's maintainability and adaptability.

[0051] Example 3

[0052] In one embodiment, such as Figure 8 As shown, the pressurized powertrain system 2 includes: a servo drive module 21, which is composed of a transmission chain consisting of a servo motor 211, a reduction gearbox 212, and a gearbox 213; and an electric cylinder actuation module 22, which includes an electric cylinder body base 221 connected to the output shaft of the gearbox 213. The output end of the electric cylinder body base 221 is connected to the correction assembly 3 through a floating ball joint mechanism 222, wherein the floating ball joint mechanism 222 is provided with an axial pressure plate limiting structure 2221.

[0053] In detail, the servo drive module 21 consists of a transmission chain formed by a servo motor 211, a reduction gearbox 212, and a gearbox 213. The servo motor 211 has position control and speed adjustment functions, enabling it to accurately drive the subsequent electric cylinder execution module 22 according to a pre-set program, achieving stable and controllable pressure on the solid-state battery and meeting the pressure loading speed requirements of the solid-state battery at different process stages. The electric cylinder body base 221 and the output shaft of the gearbox 213 are connected by a spline to ensure the smoothness and reliability of power transmission. The output thrust of the electric cylinder body base 221 can reach 150 tons, and its output end is connected to the correction component 3 through a floating ball joint mechanism 222. The floating ball joint mechanism 222 can automatically adjust within a certain angle range, effectively compensating for minor angular deviations that may occur due to the solid-state battery or the fixture itself, ensuring uniform pressure application. Simultaneously, the floating ball joint mechanism 222 also has an axial pressure plate limiting structure 2221, which can limit the axial displacement of the axial pressure plate, preventing equipment damage or abnormal pressure application due to excessive displacement, with the limiting accuracy within a suitable range.

[0054] Example 4

[0055] In one embodiment, such as Figure 12 As shown, the correction assembly 3 is composed of an output connection plate 31, a flexible pressure holding plate 32 and a fixed connection plate 33 connected in sequence; wherein, the flexible pressure holding plate 32 is made of rubber.

[0056] In detail, the correction assembly 3 consists of an output connecting plate 31, a flexible pressure-holding plate 32 with a special elastic corrugated plate structure, and a fixed connecting plate 33, which are sequentially connected by bolts. Under the pressure applied by the pressurized powertrain system 2, the flexible pressure-holding plate 32 undergoes elastic deformation to maintain pressure against the solid-state battery surface, thus automatically adapting to subtle geometric differences on the solid-state battery surface and ensuring uniform pressure distribution. Simultaneously, the correction assembly 3 achieves adaptive pressure control through the rubber-material flexible pressure-holding plate 32, effectively alleviating localized stress concentration and improving the contact stability of the battery interface. Under the axial pressure of the pressurized powertrain system 2, the flexible pressure-holding plate 32 undergoes controllable elastic deformation, achieving intelligent pressure holding through the following mechanism: when the pressure reaches 5-30 MPa, the curved microstructure of the flexible pressure-holding plate 32 undergoes gradient deformation, precisely matching the geometric differences on the solid-state battery surface.

[0057] Example 5

[0058] In one embodiment, such as Figure 4As shown, the battery carrying system 4 includes: a layer plate assembly array 41, the layer plate assembly 411 having guide post through holes adapted to the guide post 16, and adjacent layer plate assemblies 411 being mounted on the guide post 16 via guide sleeves; the top end of the layer plate assembly 411 having a plurality of mounting holes for fixing PCB assemblies 42; the PCB assemblies 42 being respectively mounted on both ends of the layer plate assembly 411.

[0059] Specifically, the layer assembly array 41 includes several layer assemblies 411 (the specific number of layer assemblies is determined according to the number of layers of the solid-state battery cell), which are made of aluminum alloy. The surface of the layer assembly 411 is anodized to give it good wear resistance, corrosion resistance, and a low coefficient of friction, thereby reducing damage to the surface of the solid-state battery. The layer assembly 411 is provided with guide post through holes 4116.d that are adapted to the guide post 16 to ensure that the layer assembly 411 can slide smoothly and be positioned on the guide post 16. Adjacent layer assemblies 411 are mounted on the guide post 16 through guide sleeves. The spacing between adjacent layer assemblies 411 can be flexibly adjusted according to the design requirements of the solid-state battery cell. The position of the layer assembly 411 is fixed by adjusting the locking nut installed on the guide post 16 to ensure the stability and consistency of the solid-state battery cell during the loading and unloading process. PCB assemblies 42 are respectively installed at both ends of the layer board assembly 411. Several mounting holes are evenly provided at the top of each layer board assembly 411 for fixing the PCB assembly 412. The PCB assembly 42 can change the position of the mounting holes to adapt to the size of solid-state batteries of different sizes. The PCB assembly 412 can realize the electrical connection and signal acquisition functions of the solid-state battery cells. At the same time, it can withstand a certain pressure without damage or degradation of electrical performance, ensuring that the solid-state battery works normally under pressure and communicates stably with the external control system.

[0060] In a preferred embodiment, both the first pressure detection device 43 and the second pressure detection device 44 include a heat-insulating plate, a pressure sensor mounting plate, and a pressure sensor; the heat-insulating plate is respectively disposed at the beginning and end of the layer assembly array 41, and the heat-insulating plate is connected to the pressure sensor through the pressure sensor mounting plate.

[0061] Specifically, both the first heat-insulating plate 431 and the second heat-insulating plate 441 are made of ceramic fiber composite material, possessing excellent heat insulation performance. This effectively isolates the heat generated during solid-state battery operation from the pressure sensor, ensuring accurate pressure detection. Their dimensions are compatible with the shelf assembly 411, and they are fixed to the shelf assembly 411 with screws, ensuring no displacement or detachment during stress. Both the first pressure sensor mounting plate 432 and the second pressure sensor mounting plate 442 are made of carbon steel and are used to mount the first pressure sensor 433 and the second pressure sensor 443, respectively, and are tightly connected to their corresponding heat-insulating plates. The mounting plates and heat-insulating plates are fixedly connected with countersunk screws, ensuring a secure and reliable connection. The mounting plates have mounting holes matching the pressure sensors, ensuring accurate installation and positioning of the pressure sensors and accurate transmission of the pressure from the solid-state battery to the pressure sensors. Both the first pressure sensor 433 and the second pressure sensor 443 are strain gauge pressure sensors, capable of real-time and accurate detection of the pressure on the solid-state battery at different locations, and converting the pressure signal into an electrical signal output to the monitoring terminal of the control system. By monitoring the pressure at the beginning and end of the layer assembly array 41 in real time, dynamic analysis and precise control of the pressure distribution of the solid-state battery can be achieved, ensuring that the solid-state battery is always in a suitable pressure environment during the production process, and guaranteeing the stable performance and quality of the solid-state battery.

[0062] In a preferred embodiment, such as Figures 9-10As shown, the layer assembly 411 includes: a substrate layer 4112, which integrates a fluid cooling system 4119. The fluid cooling system 4119 includes a central cooling region and an edge cooling region. The central cooling region is a biomimetic flow channel with a cross-section resembling a leaf vein branching structure. The edge cooling region is an annular closed flow channel, the inner diameter of which is adapted to the outer edge of the biomimetic flow channel. The fluid cooling system adopts a parallel dual-loop structure. A heating device 4114 is connected to the substrate layer. A temperature detection device 4115 is built into the substrate layer 4112. A control system is connected to the fluid cooling system 4119, the heating device 4114, and the temperature detection device 4115. By designing the fluid cooling system 4119 within the substrate layer 4112 and equipping it with a central cooling region composed of biomimetic flow channels and an edge cooling region composed of an annular closed flow channel, a highly efficient heat dissipation structure is formed. The biomimetic flow channel's leaf-vein-like branching design allows for rapid coolant distribution and even heat removal, while the edge cooling zone focuses on suppressing the thermal edge effect, preventing excessive heat accumulation at the edges. The control system connects the fluid cooling system, heating device 4114, and temperature detection device 4115, automatically adjusting the coolant flow rate and direction, as well as the power of heating device 4114, based on real-time temperature data to achieve dynamic temperature balance. During initial equipment startup, the control system quickly activates heating device 4114 to raise the temperature; under high load operation, it increases cooling intensity to suppress overheating. Heating device 4114 is connected to substrate layer 4112, enabling direct heat transfer and facilitating heating. Temperature detection device 4115 is built into substrate layer 4112 to monitor the internal temperature in real time, allowing for precise temperature control and monitoring of the entire layer assembly.

[0063] In a preferred embodiment, the central cooling region is a biomimetic flow channel with a cross-section resembling a leaf vein-like branching structure; the edge cooling region is an annular closed flow channel with its inner diameter adapted to the outer edge of the biomimetic flow channel; the fluid cooling system 4119 adopts a parallel dual-loop structure. The biomimetic leaf vein-like branching structure significantly reduces fluid flow resistance and improves the surface area utilization of the flow channel, achieving over 60% higher efficiency compared to traditional straight flow channels, thus maximizing heat transfer efficiency per unit volume. The branching structure forms multi-stage flow distribution, which, combined with the parallel dual-loop design, makes the fluid distribution more uniform within the substrate layer, avoiding thermal stress concentration caused by localized overheating. The annular structure matches the outer edge of the biomimetic flow channel, forming a closed thermal boundary layer that effectively suppresses temperature gradients in the edge region. The fluid cooling system 4119 with a parallel dual-loop structure allows two independent cooling channels to operate simultaneously, improving cooling efficiency. Under high heat loads, the dual loops effectively share the cooling load, reducing the overall temperature and enhancing system reliability. The parallel dual-loop structure means that the annular closed flow channel and the biomimetic flow channel can work simultaneously and operate independently. The coolant in the two loops can circulate in their respective cooling areas according to their specific flow rates and other parameters, without interfering with each other, thus more accurately meeting the cooling needs of different areas at the center and the periphery.

[0083] Example 8

[0084] In one embodiment, such as Figure 4 As shown, the position installation detection system 7 includes a sensor mounting bracket 71, a position sensor 721, and a position sensor mounting plate 73. The sensor mounting bracket 71 has an arc-shaped mounting groove adapted to the pull rod assembly 11. The position sensor 721 is fixed to the sensor mounting bracket 71 by the sensor mounting plate 72. The position sensor mounting plate 73 is fixed to the left side of the push plate 14 and cooperates with the position sensor 721 to detect the position of the push plate movement to ensure that overpressure is not applied.

[0085] Specifically, the sensor mounting bracket 71 is made of aluminum alloy and has an arc-shaped mounting groove that matches the pull rod assembly 11. It is fixed to the pull rod assembly 11 with bolts and can be flexibly adjusted in position along the circumference of the pull rod assembly 11 to adapt to different detection needs. The design of the sensor mounting bracket 71 ensures the installation stability and reliability of the position sensor 721. Its arc-shaped structure can, to some extent, mitigate the impact of minor deformations of the pull rod assembly 11 under stress on the sensor installation, ensuring the measurement accuracy of the position sensor 721. The position sensor 721 is a magnetic grating position sensor, which is firmly fixed to the sensor mounting bracket 71 by the sensor mounting plate 72.

The position sensor mounting plate 73 is fixed to the left side of the push plate 14 and tightly connected to it with screws, ensuring the accuracy and stability of its installation position. The position sensor mounting plate 73 and the position sensor 721 work together to form a closed-loop position installation detection system 7, which can monitor the displacement of the push plate 14 in real time and feed the displacement signal back to the control system. The position installation detection system can protect the pressure fixture's push plate from extreme positions during forward and backward movement, ensuring no overpressure. The control system compares and analyzes the displacement signal with pre-set process parameters, and adjusts the output of the pressurizing powertrain system 2 in a timely manner to achieve precise control of the solid-state battery pressure application process, ensuring that the solid-state battery is always at the optimal pressure position during production, thus improving the performance and quality of the solid-state battery.

[0086] The working principle of the high-pressure clamping machine is as follows: During the solid-state battery production process, the battery cells are first placed on the layer assembly 411 of the battery carrying system 4, and the cell positioning system 8 performs preliminary positioning of the cells. After the pressurization power assembly system 2 is started, the servo drive module 21 drives the electric cylinder execution module 22 to move along the guide column 16 towards the solid-state battery, and the correction component 3 applies pressure evenly to the surface of the solid-state battery. During the pressure application process, the first pressure detection device 43 and the second pressure detection device 44 monitor the pressure on the solid-state battery in real time and feed the pressure signal back to the control system. The control system compares the pressure signal with the preset pressure value and adjusts the output of the servo drive module 21 to better control the stroke of the electric cylinder execution module 22, thereby achieving closed-loop control of the solid-state battery pressure and ensuring that the solid-state battery is always in a stable and uniform high-pressure environment. At the same time, the distance adjustment system 7 adjusts the position of the battery carrying system 4 on the guide column 16 according to the size and process requirements of the solid-state battery to ensure that the interlayer distance of the solid-state battery cells meets the design requirements during the stacking process. The position installation detection system 9 can monitor the position changes of the push plate 14 in real time, further ensuring the accuracy and stability of pressure application. The tensioning and positioning mechanism ensures that the guide column 16-layer plate assembly array is inserted on it throughout the process, and can also be tightly connected to the front and rear end plates to prevent equipment failure or abnormal pressure application caused by loosening of the tie rod, providing a solid foundation for the normal operation of the entire high-pressure fixture.

[0087] The specific workflow of the high-pressure fixture is as follows: the equipment is preheated to the set temperature for the solid-state battery packaging process; the solid-state battery to be packaged is placed into the preset station of the shelf assembly; the battery loading status is automatically detected by the cell in-situ sensor integrated in the shelf assembly, confirming that the station is fully loaded; the pressurization powertrain system is started, driving the pusher plate to move forward; the correction component corrects the displacement trajectory of the pusher plate in real time to ensure that the pressure direction is vertical; the shelf assembly slides precisely along the guide column, pressing the battery to the set pressure value and entering the pressure holding state; the charging and discharging power supply is started, executing the preset charging and discharging protocol; the temperature, pressure, and current / voltage are dynamically adjusted synchronously to achieve multi-parameter closed-loop control; after the process is completed, the pressurization powertrain system reverses; the spacer chain component precisely pulls the shelf assembly back to the initial design position; the packaged solid-state battery is removed; the equipment performs sensor calibration, mechanism reset, and abnormal diagnosis, ready for the next cycle.

[0088] The application of this high-pressure clamp in solid-state battery production enables the application of high pressure (up to 150 tons) to solid-state batteries. Through various detection and control methods, it ensures the uniformity and stability of pressure, effectively improving the cell compaction density and interfacial contact performance of solid-state batteries, thereby enhancing their energy density, cycle life, and overall performance stability. Furthermore, the addition of positioning and adjustment functions ensures improved accuracy and consistency in solid-state battery production, reducing the defect rate and increasing production efficiency and economic benefits. The device's rational structural design allows it to meet the continuous operation requirements of large-scale solid-state battery production, providing strong technical support and equipment assurance for the development of the solid-state battery industry.
