[0015] When either the first pressure mechanism or the second pressure mechanism is in operation, the controller controls the drive component to stop.

[0016] In one embodiment, the mold plate includes:

[0017] A turntable, rotatable about a vertical axis, wherein the first pressure mechanism and the second pressure mechanism are disposed on at least one side of the turntable along the vertical direction; and

[0018] Multiple base supports are arranged at intervals along the circumference of the turntable and together with the turntable define multiple receiving slots for accommodating the mold.

[0019] In one embodiment, the first pressure mechanism includes a first positioning member and a first pressure boosting member, the first positioning member and the first pressure boosting member being located on both sides of the turntable along the vertical direction, and both being able to move closer to or further away from the turntable; the first positioning member is used to lock the mold, and the first pressure boosting member is used to apply pressure to the material inside the mold;

[0020] The second pressure mechanism includes a second positioning member and a second pressure boosting member.

[0021] In one embodiment, both the first positioning member and the second positioning member are located above the turntable, and both the first pressure booster and the second pressure booster are located below the turntable; the base includes:

[0022] The tray is located below the turntable; and

[0023] An elastic element connects the tray and the turntable, and together with the tray and the turntable, defines a receiving groove.

[0024] In one embodiment, the base is equipped with a sensor electrically connected to the controller, which is used to send a positioning signal to the controller based on the positioning of the mold;

[0025] When the positioning signal is not received, the controller controls the first pressure mechanism and / or the second pressure mechanism to be in an idle state.

[0026] In one embodiment, the solid-state battery assembly apparatus further includes:

[0027] The equipment's external frame defines the working space;

[0028] The mold plate, at least a portion of the first pressure mechanism, and at least a portion of the second pressure mechanism are all located within the working space.

[0029] In one embodiment, the first pressure mechanism includes a first operating handle, and the second pressure mechanism includes a second operating handle, wherein the first and second operating handles are located at the top of the device's outer frame; and / or,

[0044] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] The manufacturing process of all-solid-state batteries requires sample preparation and testing. Testing includes various aspects such as ionic conductivity, electronic conductivity, voltage window, rate capability, and cycle performance. Similarly, the performance evaluation of the positive electrode, negative electrode, and other related materials must be conducted under the same sealed conditions to ensure the accuracy and consistency of the data.

[0047] Traditional assembly methods employ a single-station sequential operation: first, the electrolyte material is placed into a mold and pressure is applied, requiring a certain time to achieve full molding; then, the positive electrode mixture or positive electrode sheet is added, and pressure is applied again, again requiring sufficient time; finally, the negative electrode mixture or negative electrode sheet is added and pressed. Because each step must be executed strictly in sequence, and the next step cannot begin until the previous one is completed, the entire assembly process involves significant waiting times. This operational mode not only relies heavily on manual monitoring, increasing labor costs, but also severely restricts production efficiency.

[0048] To address the above problems, this application provides a solid-state battery assembly apparatus and method. The solid-state battery assembly apparatus includes a mold disk, a first pressure mechanism, and a second pressure mechanism. The first and second pressure mechanisms cooperate with the mold disk to apply pressure to the material inside the mold. The first and second pressure mechanisms can operate independently, reducing inter-process waiting time through parallel operation, thereby improving production efficiency, reducing waiting time, and lowering labor costs.

[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] Combination Figure 1 This application provides an embodiment of a solid-state battery assembly apparatus 100. The solid-state battery assembly apparatus 100 includes a mold plate 30, a first pressure mechanism 40, and a second pressure mechanism 50.

[0051] The mold disk 30 is rotatably mounted to support multiple molds 200. The molds 200 are used to contain electrolytes, positive or negative electrode materials, etc., during pressing or forming. The mold disk 30 can be designed to rotate manually, allowing the operator to rotate it as needed to move the molds 200 to a designated position. Alternatively, the mold disk 30 can be configured to rotate via a drive unit that drives it to rotate at preset angles or time intervals.

[0052] The first pressure mechanism 40 cooperates with the mold plate 30 to apply pressure to the material inside the mold 200; the second pressure mechanism 50 cooperates with the mold plate 30 to apply pressure to the material inside the mold 200. The first pressure mechanism 40 and the second pressure mechanism 50 are used to press the electrolyte material, the positive electrode material, and the negative electrode material. Optionally, the first pressure mechanism 40 and the second pressure mechanism 50 can be a hydraulic press, a pneumatic press, or a motor-driven press, which is not limited here.

[0053] The first pressure mechanism 40 and the second pressure mechanism 50 are arranged circumferentially along the mold plate 30 and are configured to operate independently. Independent operation of the first pressure mechanism 40 and the second pressure mechanism 50 means that their operation is not linked. For example, both the first pressure mechanism 40 and the second pressure mechanism 50 have operating and idle states. When the first pressure mechanism 40 is operating, the second pressure mechanism 50 can also be operating or idle, and vice versa. Alternatively, the first pressure mechanism 40 and the second pressure mechanism 50 may each employ two separate drive components, and the operating and idle states of the first pressure mechanism 40 or the second pressure mechanism 50 can be switched by controlling different drive components.

[0054] "Idle state" refers to a state in which neither the first pressure mechanism 40 nor the second pressure mechanism 50 applies pressure to the material inside the mold 200, while "working state" refers to a state in which at least one of the first pressure mechanism 40 or the second pressure mechanism 50 is applying pressure to the material inside the mold 200.

[0055] In conjunction with the above structure, when assembling batteries using the solid-state battery assembly apparatus 100 provided in this application embodiment, the mold disk 30 can be fully utilized. The rotating mold disk 30 allows multiple molds 200 to move between the first pressure mechanism 40 and the second pressure mechanism 50. When the operator uses the first pressure mechanism 40 to press the electrolyte layer, after the mold disk 30 rotates, the second pressure mechanism 50 can immediately press the electrolyte layer and positive electrode material in another mold 200 without waiting for the first pressure mechanism 40 to be completely idle. Subsequently, the first pressure mechanism 40 can be reused to perform final pressing on the mold 200 with added negative electrode material. This design allows multiple pressing processes to be performed in parallel, shortening the assembly cycle of a single battery and improving overall production efficiency.

[0056] Thus, the solid-state battery assembly apparatus 100 proposed in this application, by providing a rotatable mold disk 30 and configuring a first pressure mechanism 40 and a second pressure mechanism 50 arranged circumferentially along the mold disk 30 and capable of independent operation, allows the mold disk 30 to support multiple molds 200 and facilitate the transfer of the molds 200 between the first pressure mechanism 40 and the second pressure mechanism 50, enabling multiple pressing processes to be performed in parallel or alternately. Therefore, the technical solution of this application effectively avoids the limitation of traditional single-station operations that require waiting for the previous process to complete before proceeding to the next, thereby improving the overall efficiency of battery assembly, reducing manpower input, and shortening the overall turnaround time.

[0057] In one embodiment, the solid-state battery assembly apparatus 100 further includes a drive unit 33 and a controller.

[0058] The drive unit 33 is connected to the mold disk 30 and is used to drive the mold disk 30 to rotate; the controller is electrically connected to the drive unit 33, the first pressure mechanism 40 and the second pressure mechanism 50; based on the automatic mode of the mold disk 30, the controller is configured to control the drive unit 33 according to the working state of the first pressure mechanism 40 and the second pressure mechanism 50.

[0059] The drive unit 33 is connected to the mold disk 30 and is used to drive the mold disk 30 to rotate. The drive unit 33 can be a stepper motor or a servo motor, and is connected to the mold disk 30 through a gear transmission mechanism, belt transmission mechanism, or chain transmission mechanism to achieve precise rotation of the mold disk 30. Alternatively, the drive unit 33 can also be a pneumatic or hydraulic rotary actuator, which drives the mold disk 30 to rotate intermittently or continuously by controlling air pressure or hydraulic pressure.

[0060] The controller is electrically connected to the drive unit 33, the first pressure mechanism 40, and the second pressure mechanism 50. The controller may be a programmable logic controller, capable of receiving status signals from the first pressure mechanism 40 and the second pressure mechanism 50, and sending control commands to the drive unit 33.

[0061] In this embodiment, the mold disk 30 has two modes: manual and automatic. In manual mode, the operator manually rotates the mold disk 30. In automatic mode, the controller controls the drive component 33 to rotate the mold disk 30. For example, the mold disk can be set to have 10 mold positions, and the drive component rotates 36° each time. In automatic mode, it automatically rotates 36° when the conditions are met; in manual mode, the rotation button needs to be clicked to make the drive component rotate 36°.

[0062] In the automatic mode of the mold platen 30, the controller is configured to control the drive unit 33 based on the operating status of the first pressure mechanism 40 and the second pressure mechanism 50. Specifically, the controller determines whether rotation of the mold platen 30 is permitted by receiving status feedback signals from the first pressure mechanism 40 and the second pressure mechanism 50. The status feedback signals are used to indicate whether the first pressure mechanism 40 or the second pressure mechanism 50 is in an operating state or an idle state.

[0063] This embodiment introduces a drive component 33 and a controller, and the controller controls the drive component 33 according to the working state of the first pressure mechanism 40 and the second pressure mechanism 50, thereby realizing the automated rotation of the mold disk 30, reducing manual intervention, improving the continuity of operation, and enhancing the automation level of all-solid-state battery sample preparation.

[0064] Optionally, in one embodiment of this application, when both the first pressure mechanism and the second pressure mechanism 50 are in an idle state, the controller can control the drive member 33 to drive the mold disk 30 to rotate; when either the first pressure mechanism or the second pressure mechanism 50 is in a working state, the controller controls the drive member 33 to stop.

[0065] The controller can detect the position or pressure of the first pressure mechanism 40 and the second pressure mechanism 50 by installing sensors on them, thereby determining the state of the first pressure mechanism 40 and the second pressure mechanism 50. For example, the controller can determine that the first pressure mechanism 40 and the second pressure mechanism 50 are in working condition when the actual pressure value applied by the first pressure mechanism 40 and the second pressure mechanism 50 reaches a preset threshold, and otherwise determine that they are in idle condition. Alternatively, the controller can monitor the drive command status of the pressure mechanism. When no pressure application command is issued, it is determined that it is in idle condition, and when the pressure application command is active, it is determined that it is in working condition.

[0066] When both the first pressure mechanism 40 and the second pressure mechanism 50 are idle, the controller issues a command to start the drive unit 33 and drive the mold disk 30 to rotate at a preset speed. This rotation can be continuous or stepwise to accurately position the next mold 200 to be processed to the next station.

[0067] Once the controller detects that either the first pressure mechanism 40 or the second pressure mechanism 50 is in operation, it controls the drive 33 to stop, ensuring that the mold plate 30 remains stationary during pressure operation, thus avoiding equipment damage, operational errors, or product defects caused by the movement of the mold plate 30.

[0068] Through the above technical solution, the mold plate 30 in this embodiment moves only during pressureless operation, avoiding interference with the ongoing pressure application process, thereby ensuring pressing quality and equipment safety. Simultaneously, when either the first pressure mechanism 40 or the second pressure mechanism 50 is in operation, the controller stops the drive component 33, preventing the mold plate 30 from rotating unexpectedly during pressure application. This eliminates the risk of equipment damage due to motion interference and reduces the need for manual monitoring and intervention, making the entire assembly process more automated and reliable.

[0069] Combination Figure 1 and Figure 2 In some embodiments, the mold plate 30 includes a turntable 31 and a plurality of base supports 35.

[0070] The turntable 31 is the main structure of the mold platen 30. The turntable 31 can rotate around a vertical axis, and multiple molds 200 can be placed horizontally. Optionally, the turntable 31 can be a circular or polygonal flat plate structure, with its center connected to the output end of the drive unit 33. The first pressure mechanism 40 and the second pressure mechanism 50 are disposed on at least one side of the turntable 31 along the vertical direction. Optionally, the first pressure mechanism 40 and the second pressure mechanism 50 can be disposed entirely above the turntable 31, entirely below the turntable 31, or partially above and partially below.

[0071] Multiple base supports 35 are arranged at intervals along the circumference of the turntable 31, and together with the turntable 31, they define multiple receiving slots 311 for receiving the mold 200. The base supports 35 can be designed as groove structures fixed to the surface of the turntable 31, or they can be detachable independent tray units connected to the turntable 31 by snaps, bolts or other connection methods.

[0072] For example, the turntable 31 has multiple openings that match the shape of the base 35. The base 35 is connected below the turntable 31 and aligned with the openings, thus forming a receiving groove together with the turntable 31. The opening of the receiving groove faces upward, facilitating the placement and removal of the mold 200 by the operator. The receiving groove 311 provides a precise placement space for the mold 200. The shape, size, and depth of the receiving groove 311 can be customized according to the mold 200 used to ensure that the mold 200 can be smoothly placed and removed and maintain a high degree of stability within it.

[0073] Combination Figure 1 In some embodiments, the first pressure mechanism 40 includes a first positioning member 41 and a first pressure boosting member 43. The first positioning member 41 and the first pressure boosting member 43 are respectively located on both sides of the turntable 31 in the vertical direction, and both can move closer to or further away from the turntable 31.

[0074] The first positioning element 41 is used to lock the mold 200, fixing it in a predetermined position during the pressing process to prevent displacement or tilting under pressure. For example, the first positioning element 41 includes a positioning rod extending vertically, configured as a lead screw, and is connected to a base, which may be part of a housing. By rotating the positioning rod, the first positioning element 41 can move vertically closer to or further away from the mold 200. Alternatively, the first positioning element 41 can also be driven by a guide rail and slider mechanism in conjunction with a cylinder or motor, which will not be elaborated here. The first positioning element 41 can be a gripper that uses pneumatic or hydraulic drive to clamp the mold 200; or it can be a limiting block or guide groove that matches the shape of the mold 200, restricting the movement of the mold 200 through physical contact.

[0075] The first pressurizing component 43 is used to provide pressing force. It can be a hydraulic cylinder or a pneumatic cylinder, which acts directly or indirectly on the upper surface of the mold 200 through a piston rod; or it can be a press head driven by an electric screw, which controls the rotation of the screw through a motor to realize the up and down movement of the press head and the application of pressure.

[0076] The first positioning member 41 and the first pressure boosting member 43 are located on both sides of the turntable 31 along the vertical direction. For example, the first positioning member 41 can be set above the turntable 31 to position the mold 200 from above, while the first pressure boosting member 43 can be set below the turntable 31 to apply pressure to the mold 200 by moving upward.

[0077] The second pressure mechanism 50 includes a second positioning element 51 and a second pressure boosting element 53. Similarly, the second positioning element 51 is used to lock the mold 200. For example, the second positioning element 51 includes a positioning rod extending vertically, configured as a lead screw, and is connected to a base, which may be part of a housing. By rotating the positioning rod, the second positioning element 51 can be moved closer to or further away from the mold 200 in the vertical direction. Alternatively, the second positioning element 51 can also be implemented using a guide rail and slider mechanism in conjunction with a cylinder or motor drive, which will not be elaborated further here. The second positioning element 51 can be a pneumatically or hydraulically driven gripper clamping the mold 200; or it can be a limiting block or guide groove that matches the shape of the mold 200, restricting the movement of the mold 200 through physical contact.

[0078] The second pressurizing component 53 is used to provide pressing force. It can be a hydraulic cylinder or a pneumatic cylinder, which acts directly or indirectly on the upper surface of the mold 200 through a piston rod; or it can be a press head driven by an electric screw, which controls the rotation of the screw through a motor to realize the up and down movement of the press head and the application of pressure.

[0079] The second positioning member 51 and the second pressure boosting member 53 are located on both sides of the turntable 31 along the vertical direction. For example, the second positioning member 51 can be set above the turntable 31 to position the mold 200 from above, while the second pressure boosting member 53 can be set below the turntable 31 to apply pressure to the mold 200 by moving upward.

[0080] In this embodiment, the first positioning member 41 and the second positioning member 51 firmly fix the mold 200 in a preset position before pressing, effectively preventing the mold 200 from shifting, tilting, or shaking during the pressing process, thereby solving the problem of unstable positioning of the mold 200. The first pressure booster 43 and the second pressure booster 53 can provide pressing force. In addition, the arrangement of the first positioning member 41, the second positioning member 51, the first pressure booster 43, and the second pressure booster 53 on both sides or the top and bottom sides of the turntable 31 along the vertical direction can form a stable pressing structure, further enhancing the stability and uniformity of pressing.

[0081] Please refer to this again. Figure 1 In one embodiment, the first positioning member 41 and the second positioning member 51 are both located above the turntable 31, and the first pressure booster 43 and the second pressure booster 53 are both located below the turntable 31.

[0082] The base 35 includes a tray and an elastic element. The tray is located below the turntable 31. The elastic element connects the tray and the turntable 31 and together with the tray and the turntable 31, defines the receiving groove 311.

[0083] The pallet, serving as the direct support platform for the mold 200, sinks along with the mold 200 during pressure application. The pallet can be a metal plate or block, with its upper surface in close contact with the bottom of the mold 200 and its lower surface engaging with the pressure-boosting component below. The elastic element provides cushioning and restoring force to the pallet, ensuring the mold 200 remains stable in its non-working state and quickly returns to its original position after working. Furthermore, its elastic deformation absorbs some impact, making the pressure application process smoother. The elastic element can be in the form of a coil spring, disc spring, rubber pad, or gas spring.

[0084] Specifically, when the first pressure mechanism 40 and the second pressure mechanism 50 are in operation, the first positioning member 41 and the second positioning member 51 located above the turntable 31 press down on the mold 200, causing the tray to sink. Simultaneously, the first pressure boosting member 43 and the second pressure boosting member 53 located below the turntable 31 move upwards, pressing against the lower surface of the tray. This upward and downward pressure method achieves precise and uniform pressure application to the material within the mold 200. When the first pressure mechanism 40 and the second pressure mechanism 50 are in an idle state, both the positioning member and the pressure boosting member retract. At this time, the restoring force of the elastic member pushes the tray upwards back to its initial position, maintaining a certain distance between the tray and the first pressure boosting member 43 and the second pressure boosting member 53, preventing the bottom support 35 from rubbing against the first pressure boosting member 43 and the second pressure boosting member 53 and affecting the rotation of the turntable 31.

[0085] Furthermore, in some embodiments, the base 35 is equipped with a sensor electrically connected to a controller for sending a positioning signal to the controller based on the positioning of the mold 200. When no positioning signal is received, the controller controls the first pressure mechanism 40 and / or the second pressure mechanism 50 to be in an idle state.

[0086] Optionally, the sensor can be in the form of a force feedback device. When the mold 200 is placed on the base 35, the sensor sends a force signal from the base 35 to the controller. The controller determines that the force on the base 35 is greater than a certain threshold, and then generates a positioning signal based on the force signal. Alternatively, the sensor can be a photoelectric sensor, which determines the presence of the mold 200 by emitting and receiving a light beam. When the mold 200 blocks or reflects the light beam, it is considered that the mold 200 is in position.

[0087] When the controller does not receive a signal indicating that the mold 200 is in place, it means that the mold 200 is not in place or is incorrectly placed. In this case, the controller will execute a preset safety control strategy, keeping the first pressure mechanism 40 and / or the second pressure mechanism 50 in an idle state, preventing them from operating. This effectively avoids the first pressure mechanism 40 and / or the second pressure mechanism 50 operating without the mold 200, preventing wear and energy consumption caused by idling, extending the equipment's service life, improving operational safety, and avoiding potential equipment damage or personal injury risks.

[0088] Combination Figure 1 In this embodiment of the application, the solid-state battery assembly apparatus 100 further includes an equipment frame 10. The equipment frame 10 is provided with a working space 11, and the mold plate 30, at least a portion of the first pressure mechanism 40 and at least a portion of the second pressure mechanism 50 are all located in the working space 11.

[0089] The equipment frame 10 provides a mounting base for the mold plate 30, the first pressure mechanism 40, and the second pressure mechanism 50. Optionally, the working space 11 defined by the equipment frame 10 can be a closed space or an open space, and is not limited here.

[0090] Exemplarily, the device frame 10 is formed as a glove box. A glove box is a sealed container typically filled with an inert gas, such as nitrogen or argon, designed to provide a controlled environment free of water, oxygen, or with low water and oxygen content. The workspace 11 is the space within the device frame 10 used for operations, isolating the external environment from the internal operating area to prevent the entry of water vapor and oxygen from the outside air, thereby protecting the battery materials. The mold plate 30, at least a portion of the first pressure mechanism 40, and at least a portion of the second pressure mechanism 50 are all located within the workspace 11 to ensure that the entire pressing and assembly process of the battery materials is carried out in a controlled environment, preventing the materials from being contaminated by water and oxygen during operation.

[0091] In this regard, this application further proposes that the first pressure mechanism 40 includes a first operating handle 411, and the second pressure mechanism 50 includes a second operating handle 511, with the first operating handle 411 and the second operating handle 511 located on the top of the equipment outer frame 10.

[0092] The first operating handle 411 and the second operating handle 511 are mechanical components used for manually controlling the first pressure mechanism 40 and the second pressure mechanism 50. For example, the first operating handle 411 is part of the first positioning member 41, and the second operating handle 511 is part of the second positioning member. Rotating the first operating handle 411 can drive the first positioning member 41 closer to or further away from the mold 200, and rotating the second operating handle 511 can drive the second positioning member 51 closer to or further away from the mold 200. The exposed first operating handle 411 and the second operating handle 511 facilitate operation by workers. In addition, the exposed first operating handle 411 and the second operating handle 511 can reduce the risk of wear and tear on the gloves of the equipment frame 10, reduce the possibility of inert gas leakage and contamination of the workspace 11 due to glove damage, thereby ensuring the environmental requirements for all-solid-state battery processing.

[0093] The equipment frame 10 has an operating side, and gloves are provided on the operating side. The operating side typically refers to the front or side of the equipment frame 10, which is designed with openings for operator operation, and gloves are installed at these openings. The first pressure mechanism 40 is closer to the operating side than the second pressure mechanism 50. In actual operation, tasks requiring high operator involvement can be arranged at the first pressure mechanism 40, while tasks requiring less operator involvement can be arranged at the second pressure mechanism. This allows operators to perform operations closer to the first pressure mechanism 40, reducing movement frequency and improving assembly efficiency.

[0094] Of course, in some other embodiments, the equipment frame 10 may also be an open structure, forming an open working space 11, so that the staff can easily interact with the mold plate 30, the first pressure mechanism 40 and the second pressure mechanism 50.

[0095] In one embodiment, the first pressure mechanism 40 is provided with a first pressure sensor for detecting a first pressure value applied by the first pressure mechanism 40; the second pressure mechanism 50 is provided with a second pressure sensor for detecting a second pressure value applied by the second pressure mechanism 50. The first and second pressure sensors can be piezoresistive sensors, which reflect pressure by measuring the change in resistance after being compressed, or they can be piezoelectric sensors, which convert pressure into an electrical charge signal using the piezoelectric effect. The first and second pressure sensors are electrically connected to a controller.

[0096] The controller is responsible for receiving and processing data from the first and second pressure sensors. The controller includes a timing module, which can be an internal software timer that records time using the system clock, or a separate hardware real-time clock chip that provides timestamps.

[0097] The solid-state battery assembly device 100 also includes an interaction component 20, which is connected to the device's outer frame 10 and electrically connected to the controller. The interaction component 20 serves as a human-machine interface, used to intuitively display key parameters to the operator. For example, the interaction component 20 can be a touchscreen display integrating display and input functions; or it can be a display screen combined with physical buttons, etc.

[0098] Understandably, the interactive component 20 can at least display the first pressure value, the second pressure value, the running time of the first pressure mechanism 40, and the running time of the second pressure mechanism 50, so that staff can understand the operating status and key parameters during the assembly process, thereby enabling them to promptly detect and correct pressure deviations or time anomalies, and avoid material damage or product quality problems caused by inaccurate parameters.

[0099] In addition, the interactive component 20 can also be used to display a first preset pressure value, a second preset pressure value, a first preset time, and a second preset time. The first preset pressure value is the target pressure value that the first pressure mechanism 40 needs to achieve. By comparing the real-time first pressure value with the first preset pressure value, the operator can determine whether the first pressure mechanism 40 meets the production conditions, facilitating adjustments. Similarly, the second preset pressure value is the target pressure value that the second pressure mechanism 50 needs to achieve. By comparing the real-time second pressure value with the second preset pressure value, the operator can determine whether the second pressure mechanism 50 meets the production conditions. The first preset time is the pressure holding time required by the first pressure mechanism 40. Comparing the operating time of the first pressure mechanism 40 with the first preset time helps the operator monitor the pressing process, allowing for the scheduling of subsequent processes and improving work efficiency. Similarly, the second preset time is the pressure holding time required by the second pressure mechanism 50. Comparing the operating time of the second pressure mechanism 50 with the second preset time helps the operator monitor the pressing process.

[0100] In addition, the interactive component 20 allows users to change the above parameters and other parameters through touch, pressing buttons and other operations, so as to adjust the production process in real time, enabling the solid-state battery assembly device 100 to provide a variety of different pressing forces and times, thereby being compatible with the production of more products.

[0101] As shown in the figure, the interactive component 20 is set on the side adjacent to the operating side of the device frame 10 to avoid occupying the space on the operating side and to facilitate operation by the staff.

[0102] Based on the aforementioned solid-state battery assembly apparatus 100, another aspect of this application provides an assembly method, the method comprising:

[0103] S1: Place the mold containing the electrolyte material into the mold plate, and press the electrolyte layer through the first pressure mechanism.

[0104] This refers to placing the mold 200, which is pre-filled with electrolyte material, into the receiving groove 311 of the mold tray 30. This operation can be performed manually or by an automated robotic arm or feeding mechanism to meet different automation requirements. Of course, the electrolyte material can also be added to the mold 200 after it has been placed in the mold tray 30; this is not limited to this step.

[0105] S2: Place the positive electrode material into the mold and rotate the mold plate.

[0106] This refers to adding positive electrode material to the mold 200 after the electrolyte layer is pressed. This step can be done manually or through an automated feeding device. After the positive electrode material is added, the mold disk 30 is driven to rotate circumferentially, moving the current mold 200 away from the working position of the first pressure mechanism 40 and moving it to the next preset position. The rotation of the mold disk 30 can be achieved by the drive component 33, rotating one mold 200 position at a time, or it can be achieved manually by the operator. For example, for a mold disk 30 carrying ten evenly distributed molds 200, the mold disk 30 rotates 36° each time to switch to the next mold 200 position.

[0107] S3: The electrolyte layer and positive electrode material are pressed by the second pressure mechanism, causing the mold disk to rotate.

[0108] When the mold 200 containing the electrolyte layer and positive electrode material rotates to the working position of the second pressure mechanism 50, the second pressure mechanism 50 presses the material inside the mold 200. The second pressure mechanism 50 and the first pressure mechanism 40 are arranged circumferentially around the mold disk 30 and are configured to operate independently. Therefore, pressing operations can be performed in parallel while the first pressure mechanism 40 is processing other molds 200 or is idle. After the second pressure mechanism 50 completes pressing, it drives the mold disk 30 to rotate again, moving the current mold 200 out of the working area of ​​the second pressure mechanism 50 and moving it to the next station to prepare for the subsequent addition of negative electrode material and final pressing.

[0109] S4: Flip the mold, put the negative electrode material into the mold after it has been pressed by the second pressure mechanism, press it by the first pressure mechanism, assemble and remove the mold.

[0110] After the second pressure mechanism 50 completes the pressing, the mold 200 moves to the first pressure mechanism 40, where negative electrode material is added. This step can also be completed manually or by an automated feeding device. When the mold 200 containing the electrolyte layer, positive electrode material, and negative electrode material rotates to the working position of the first pressure mechanism 40, the first pressure mechanism 40 is used again to perform final pressing on all the materials in the mold 200. At this point, the first pressure mechanism 40 has completed its initial task and is idle, and can be reused for final pressing, thereby maximizing equipment utilization. After final pressing is completed, the assembled battery mold 200 is removed. This operation can be performed manually or by an automated robotic arm or ejection mechanism.

[0111] Thus, the operator can repeat steps S1 to S4.

[0112] Through the above technical solution, this application optimizes the assembly process, enabling the alternating and parallel use of the first pressure mechanism 40 and the second pressure mechanism 50, and coordinating with the rotation of the mold disk 30. This effectively solves the problems of long waiting time between processes, high labor costs, and low efficiency in traditional single-station operations. Specifically, when the first pressure mechanism 40 is pressing the electrolyte layer, after the mold disk 30 rotates, the second pressure mechanism 50 can immediately press the electrolyte layer and positive electrode material in another mold 200 without waiting for the first pressure mechanism 40 to be completely idle. Subsequently, the first pressure mechanism 40 can be reused to perform the final pressing on the mold 200 with added negative electrode material. This design allows multiple pressing processes to be performed in parallel, greatly shortening the assembly cycle of a single battery and improving overall production efficiency. At the same time, the automated rotation of the mold disk 30 reduces manual intervention, lowering operational intensity and labor costs.
