Description

Technical Field

[0001] This invention relates to the field of lithium-ion packaging technology, and in particular to a top-side sealing and dual-sealing machine for solid-state batteries. Background Technology

[0002] Entering the 21st century, with the improvement of people's consumption levels and productivity, car prices have become increasingly affordable, and cars have entered thousands of households. However, this has also brought a series of problems. Since current cars are all gasoline-powered, they rely on the combustion of fossil fuels to generate kinetic energy to propel the vehicle. But the combustion of fossil fuels produces exhaust gases containing various pollutants such as carbon dioxide, nitrogen oxides, and particulate matter, causing serious environmental pollution. Moreover, the Earth's fossil fuel reserves are limited; with increased use, the rate of depletion of fossil fuels is accelerating, ultimately leading to an energy crisis.

[0003] Since their introduction in the 1990s, lithium batteries have been widely used due to their high specific energy, long charge-discharge life, high voltage, no memory effect, fast charging, and low self-discharge rate. Because of these advantages, lithium batteries are used as power batteries in automobiles, with countries worldwide hoping that electric vehicles will replace traditional gasoline-powered vehicles to solve environmental problems and the energy crisis. However, existing lithium batteries use organic electrolytes, which pose safety risks such as flammability and explosiveness.

[0004] Current lithium batteries use organic electrolytes, which pose safety risks such as flammability and explosiveness. Compared to existing liquid lithium batteries, solid-state lithium batteries are one of the most promising technologies to replace existing high-energy-density lithium batteries. Solid-state lithium batteries offer longer cycle life and higher rate performance, with an energy density 2 to 5 times that of existing lithium batteries, fundamentally solving the safety issues of current liquid lithium batteries. Therefore, research institutes, universities, and companies worldwide are increasing their R&D investment in solid-state lithium batteries.

[0005] However, current top-side sealing and secondary sealing machines are based on liquid lithium batteries. Because there is a liquid injection process between the top-side sealing and secondary sealing processes, these machines cannot be integrated; they must be separate sets of equipment. This increases the equipment footprint and reduces the packaging efficiency of pouch cells. Currently, solid-state battery packaging still uses two separate sets of equipment based on liquid lithium batteries: a top-side sealing machine and a secondary sealing machine.

[0006] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0055] Specifically, each module connects the wiring and air passages of its functional components to the non-functional actuators below the equipment platform 101 via wiring holes 106 on the equipment platform 101. The non-functional actuators are located inside the equipment platform module. Several movable doors 103 are installed on the side of the first frame 102 to isolate the non-functional actuators from the outside environment and facilitate maintenance and replacement.

[0057] In some embodiments, the first top-side sealing module includes a second frame 201, a start button 202 mounted on the second frame 201, and a first movable clamp mounting plate 203 mounted on the second frame 201; the first movable clamp mounting plate 203 is provided with a cell positioning lower clamp 204, a cell pressure plate 205 corresponding to the cell positioning lower clamp 204, and tab positioning blocks 206 disposed on both sides of the cell positioning lower clamp 204; the first movable clamp mounting plate 203 is slidably connected to the plate guide rail 207.

[0058] Specifically, the second frame 201 serves a protective function, preventing pinching injuries during operation; the start button 202 includes two buttons, both mounted on the second frame 201. When both start buttons are pressed simultaneously, the top-side sealing program is activated. The two start buttons prevent accidental pressing; the cell positioning clamp 204 is used to fix the soft-pack battery cell, and the cell positioning clamp 204 is made of insulating material. The cell positioning clamp 204 is fixed to the first movable clamp mounting plate 203, and the cell positioning clamp can be customized to the corresponding size according to the size of the soft-pack battery cell; the cell pressure plate 205 is used to press down the aluminum-plastic film above the soft-pack battery cell to prevent relative sliding between the soft-pack battery cell and the aluminum-plastic film. The cell pressure plate 205 is made of insulating material and is fixed to the first movable clamp mounting plate 203, corresponding to the cell positioning clamp 204 and being flip-up. The tab positioning block 206 is fixed to the first movable clamp mounting plate 203 and its position is adjustable. The tab positioning block can be customized to the corresponding size according to the size and position of the tabs of the soft-pack battery cell, and the tab positioning block 206 is made of insulating material. The large plate guide rail 207 allows the first movable clamp mounting plate 203 to slide along the large plate guide rail, which is fixed to the equipment table 101.

[0059] In some embodiments, the second top-side sealing module includes a first top-sealing assembly 208, a second top-sealing assembly 209, a side-sealing assembly 210, a first actuator 211 that controls the cell pressure plate 205, a support 212, a mounting plate 213, a first ball screw 214, a first servo motor 215, and a first connecting plate 216.

[0060] One end of the support column 212 is fixed to the equipment table module 1, and the other end is connected to the mounting plate 213, forming a working area between the mounting plate 213 and the equipment table module 1; the first top sealing component 208 and the second top sealing component 209 are symmetrically installed on the mounting plate 213, and the side sealing component 210 is installed on the end of the mounting plate 213 away from the first top and side sealing module; the first connecting plate 216 forms a movable connection between the first moving clamp mounting plate 203 and the first ball screw 214, and the first servo motor 215 is used to control the first moving clamp mounting plate 203 to slide along the plate guide rail 207.

[0061] Specifically, the first top sealing assembly 208 includes a first lower actuator, a first lower heating copper mold, a first upper heating copper mold, and a first upper actuator, etc.; the first upper actuator is responsible for raising and lowering the first upper heating copper mold, and the first lower actuator is responsible for raising and lowering the first lower heating copper mold; the second top sealing assembly 209 includes a second lower actuator, a second lower heating copper mold, a second upper heating copper mold, and a second upper actuator, etc.; the second upper actuator is responsible for raising and lowering the second upper heating copper mold, and the second lower actuator is responsible for raising and lowering the second lower heating copper mold. The copper mold is raised and lowered; the side sealing assembly 210 includes a third lower actuator, a third lower heating copper mold, a third upper heating copper mold, and a third upper actuator, etc.; the third upper actuator is responsible for raising and lowering the third upper heating copper mold, and the third lower actuator is responsible for raising and lowering the third lower heating copper mold; the first top sealing assembly 208, the second top sealing assembly 209, and the side sealing assembly 210 are each partially disposed in the working area and partially disposed on the side of the mounting plate 213 away from the working area, that is, the top and side sealing of the soft-pack battery cell is completed within the working area.

[0062] The first actuator 211 is responsible for opening the cell pressure plate 205. The first actuator 211 can be a cylinder or an electric cylinder as a power source. The support column 212 is fixed at the corresponding position on the equipment table 101 to support the mounting plate 213. There are four support columns 212, and the mounting plate 213 is fixed on the four support columns. The first top sealing assembly 208, the second top sealing assembly 209, and the side sealing assembly 210 are installed at the fixed position on the mounting plate 213. The first actuator 211 is installed at the fixed position on the mounting plate 213 to control the opening of the cell pressure plate 205. A first connecting plate 216 is installed above the first ball screw 214. The first connecting plate 216 is used to connect the first movable fixture mounting plate 203 and the first ball screw 214. The first servo motor 215 is connected to the first ball screw 214 and the first connecting plate 216. The first servo motor 215 controls the sliding of the first movable fixture mounting plate 203 by controlling the first ball screw 214.

[0063] To better illustrate, the operation of the top-side sealing module 2 in this embodiment is as follows: The soft-pack battery cell to be packaged is placed in the battery cell positioning fixture 204, with the tabs of the soft-pack battery cell corresponding to the tab positioning blocks 206. The battery cell pressure plate 205 is flipped downwards by hand to press down on the top of the soft-pack battery cell, preventing it from sliding relative to the battery cell. Simultaneously, the two start buttons 202 are pressed, and the packaging process automatically starts. The first servo motor 215 controls the rotation of the first ball screw 214, driving the sliding of the first connecting plate 216, which in turn drives the first moving fixture mounting plate 203. The first moving fixture mounting plate 203 slides to the top sealing position and stops. The upper and lower heating copper in the first top sealing assembly 208... The upper and lower heating copper molds in the mold and the second top sealing assembly 209 are preheated to a certain temperature, with a temperature range of 100-300℃. The lower heating copper mold in the first top sealing assembly 208 moves upward to a fixed position, and the upper heating copper mold in the first top sealing assembly 208 moves downward to a fixed position, so that the first top sealing seal 701 is just stuck between the lower heating copper mold and the upper heating copper mold of the first top sealing assembly 208. The lower heating copper mold and the upper heating copper mold in the first top sealing assembly 208 apply a certain pressure to the first top sealing seal 701, and heat the position of the first top sealing seal 701. After heating to a certain temperature, the aluminum-plastic mold at the position of the first top sealing seal 701 is heat-sealed. Similarly, the second top sealing component 209 heat seals the second top sealing seal 702. The heat sealing of the first top sealing seal 701 and the second top sealing seal 702 is performed simultaneously. After the heat sealing is completed, the upper and lower heating copper molds in the first top sealing component 208 and the second top sealing component 209 return to their original positions.

[0064] Next, the first servo motor 215 drives the first moving fixture mounting plate 203 to continue sliding. The first moving fixture mounting plate 203 slides to the side sealing position and stops. The upper and lower heating copper molds in the side sealing assembly 210 are preheated to a certain temperature, with a temperature range of 100-300℃. The upper heating copper mold and the lower heating copper mold in the side sealing assembly 210 move to a fixed position, so that the side sealing seal 703 is just stuck between the lower heating copper mold and the upper heating copper mold of the side sealing assembly 210. The lower heating copper mold and the upper heating copper mold in the side sealing assembly 210 apply a certain pressure to the side sealing seal 703. The lower heating copper mold and the upper heating copper mold heat the side sealing position of the side sealing seal 703. After heating to a certain temperature, the aluminum-plastic film at the position of the side sealing seal 703 is heat-sealed. After the side sealing position of the side sealing seal 703 is completed, the upper and lower heating copper molds of the side sealing assembly 210 return to their original positions.

[0065] At this point, the top and side sealing of the soft-pack battery cell in the top and side sealing module 2 has been completed. Then, the first actuator 211 starts to work, causing the battery cell pressure plate 205 to flip back to its original position. After the material transfer module 3 sucks away the top and side sealed soft-pack battery cell in the battery cell positioning clamp 204 with a suction cup, the first servo motor 215 drives the first moving clamp mounting plate 203 to slide. The first moving clamp mounting plate 203 slides back to the original position of the second frame 201. At this point, the entire top and side sealing process is completed, and the process enters the material transfer process.

[0066] In some implementations, such as Figure 8 As shown, the material transfer module 3 includes a module bracket 301, a servo module 302, a first suction cup assembly 303 and a second suction cup assembly 304 mounted on the servo module, and a guide rail 305 that is slidably connected to the servo module; the module bracket 301 is used to support the servo module 302; the servo module 302 is used to drive the first suction cup assembly 303 and the second suction cup assembly 304 to slide along the guide rail 305.

[0067] In some embodiments, both the first suction cup assembly 303 and the second suction cup assembly 304 include a plurality of suction cups, a vacuum generator, and an actuator; the vacuum generator is used to control the suction and release of vacuum by the plurality of suction cups; and the actuator is used to control the raising and lowering of the plurality of suction cups.

[0068] Specifically, the actuator of the suction cup assembly can be controlled by an electric cylinder or a pneumatic cylinder; the first suction cup assembly 303 is responsible for transferring the soft-pack battery cell that has completed the second sealing process in the second sealing module 4 to the transfer module 5; the second suction cup assembly 304 is responsible for transferring the soft-pack battery cell that has completed the top side sealing process in the top side sealing module 2 to the second sealing module 4; the guide rail 305 is a linear guide rail, on which the first suction cup assembly 303 and the second suction cup assembly 304 are hung, and the first suction cup assembly 303 and the second suction cup assembly 304 can slide on the guide rail 305.

[0069] Specifically, the material transfer process of the soft-pack battery cell 7 from the top-side sealing module 2 to the second-side sealing module 4 is as follows: After the top-side sealing process of the soft-pack battery cell 7 is completed, the battery cell pressure plate 205 is opened, and the servo module 302 controls the second suction cup assembly 304 to slide horizontally in a straight line. The second suction cup assembly 304 slides in a straight line and stops directly above the battery cell positioning clamp 204. The actuator of the second suction cup assembly 304 controls several suction cups of the second suction cup assembly 304 to move downward on their own until several suction cups of the second suction cup assembly 304 contact the top of the soft-pack battery cell and continue to move downward a short distance. The vacuum generator controls several suction cups of the second suction cup assembly 304 to evacuate a vacuum. When the vacuum level reaches a set value, several suction cups of the second suction cup assembly 304 pick up the soft-pack battery cell. The core moves straight towards the second sealing module 4. After moving a set distance, the servo module 302 controls the second suction cup assembly 304 to move horizontally towards the second sealing module. When it reaches the position of the second sealing module, the actuator of the second suction cup assembly 304 controls several suction cups of the second suction cup assembly 304 to move straight downward until the soft-pack battery cell is placed in the positioning groove clamp of the second sealing module 4. At this time, the vacuum generator of the second suction cup assembly 304 controls several suction cups of the second suction cup assembly to break the vacuum. At this time, several suction cups of the second suction cup assembly no longer adhere to the soft-pack battery cell. The actuator of the second suction cup assembly controls the second suction cup assembly to move straight upward, returning to the position before the second suction cup assembly completed the material transfer task. At this time, the material transfer process of the soft-pack battery cell from the top side sealing module 2 to the second sealing module 4 is completed.

[0070] In some implementations, such as Figure 9 and Figure 10 As shown, the second sealing module 4 includes:

[0071] Second moving fixture mounting plate 401;

[0072] The positioning groove fixture 402 is installed on the second movable fixture mounting plate 401;

[0073] The central cavity guide rail 403 and the second movable clamp mounting plate 401 are slidably connected to the central cavity guide rail 403;

[0074] The second ball screw 404 and the second connecting plate 406 are connected to the second movable clamp mounting plate 401 through the second connecting plate 406.

[0075] The second servo motor 405 controls the movement of the second ball screw 404, so that the second moving fixture mounting plate 401 slides along the central cavity guide rail 403.

[0076] The secondary sealing assembly is installed at one end of the central cavity guide rail and is used to perform secondary sealing on the soft-pack battery cells that have completed the top-side sealing process.

[0077] Specifically, the second movable fixture mounting plate 401 can slide on the central cavity guide rail 403, and the positioning groove fixture 402 is fixed on the second movable fixture mounting plate 401; the positioning groove fixture 402 is used to fix the soft-pack battery cell, and the positioning groove fixture is made of insulating material; the central cavity guide rail is fixed on the equipment table 101, and the central cavity guide rail 403 allows the second movable fixture mounting plate to slide on it. The second ball screw 404 is connected to the second servo motor 405. The second ball screw 404 has a second connecting plate 406. The second connecting plate is connected to the second movable fixture mounting plate 401. The rotation of the second servo motor 405 drives the second ball screw 404 to rotate, which in turn drives the second connecting plate 406 of the second ball screw 404 to slide, and finally the second connecting plate 406 drives the movable fixture mounting plate 401 to slide.

[0078] In some embodiments, the dual-sealing assembly includes a side plate 407 fixed to the equipment platform 101 and located at one end of the central cavity guide rail 403, as well as an upper cavity 408, an upper cavity actuator 409, an upper copper mold assembly 410, an upper copper mold assembly actuator 411, an upper cavity cover 412, an upper cavity cover actuator 413, a lower cavity 414, a lower cavity actuator 415, and a vacuum connector 416.

[0079] Specifically, the upper cavity 408, upper cavity actuator 409, upper copper mold assembly 410, upper copper mold assembly actuator 411, upper cavity cover 412, upper cavity cover actuator 413, lower cavity 414, and lower cavity actuator 415 are located on the same side of the side plate 407 as the second movable clamp mounting plate 401. The upper cavity 408, upper cavity actuator 409, upper copper mold assembly 410, upper copper mold assembly actuator 411, upper cavity cover 412, upper cavity cover actuator 413, lower cavity 414, and lower cavity actuator 415 are used to perform a second sealing of the soft-pack battery cells fixed on the positioning groove clamp 402. The vacuum connector 416 is located on the side of the side plate 407 away from the second movable clamp mounting plate 401.

[0080] The sliding of the upper cavity 408 is controlled by the upper cavity actuator 409; the upper copper mold assembly 410, the upper copper mold assembly actuator 411, the upper cavity cover 412, and the upper cavity cover actuator 413 can slide together with the upper cavity 408; that is, the upper cavity 408 is fixedly connected to the upper copper mold assembly 410, the upper copper mold assembly actuator 411, the upper cavity cover 412, and the upper cavity cover actuator 413, and the upper cavity 408 is slidably connected to the side plate 407; the upper cavity actuator 409 can be a cylinder. The upper cavity actuator 409 is fixed on the side plate 407, with an electric cylinder as the power source. The upper copper mold assembly 410 is composed of key components such as a copper mold and a heating unit. The upper copper mold assembly actuator 411 controls the up-and-down movement of the upper copper mold assembly 410, and the upper copper mold assembly actuator 411 can be a pneumatic cylinder or an electric cylinder as the power source. The up-and-down sliding of the upper cavity cover 412 is controlled by the upper cavity cover actuator 413, and the upper cavity cover actuator 413 can be a pneumatic cylinder or an electric cylinder as the power source.

[0081] The upper cavity cover 412 serves as a seal during the second sealing process. The upper cavity cover 412 can slide upwards for maintenance, facilitating the inspection of the upper copper mold assembly 410. The lower cavity 414 contains a lower copper mold, a heating unit, and a spring pressure plate. The relative height of the lower copper mold and heating unit within the lower cavity 414 can be adjusted. The vertical sliding of the lower cavity 414 is controlled by the lower cavity actuator 415. The spring pressure plate in the lower cavity 414 can press down on the soft-pack battery cell 7, fixing it in place. The lower cavity actuator can be a pneumatic cylinder or an electric cylinder as a power source. The vacuum connector 416 is fixed behind the lower cavity 414 and is responsible for evacuating the vacuum during cavity sealing.

[0082] To better illustrate, the operation of the second sealing module 4 in this embodiment is as follows: After the second suction cup assembly 304 transfers the top-side sealed soft-pack battery cell from the battery cell positioning clamp 204 to the positioning groove clamp 402, the second sealing module program is started. The second servo motor 405 drives the second ball screw 404 to rotate, thereby driving the positioning groove clamp 402 to slide horizontally in a straight line into the second sealing module 4, stopping when the second sealing seal 704 is directly above the lower copper mold in the lower cavity 414. The upper copper mold assembly 410 and the lower copper mold in the lower cavity 414 have both been preheated to a certain temperature, ranging from 100 to 300°C.

[0083] The upper cavity actuator 409 controls the upper cavity 408 to move downwards. The upper copper mold assembly 410, the upper copper mold assembly actuator 411, the upper cavity cover 412, and the upper cavity cover actuator 413 can move downwards with the upper cavity 408 until the upper cavity 408 presses against the second movable clamp mounting plate 401. The lower cavity actuator 415 controls the lower cavity 414 to move upwards until the lower cavity 414 hits below the positioning groove clamp 402. The spring pressure plate in the lower cavity 414 presses down on the soft-pack battery cell. The lower copper mold in the lower cavity 414 hits below the second seal 704. The upper cavity cover actuator 413 controls the upper cavity cover 412 to move downwards until the lower cavity cover 412 hits above the upper cavity 408. At this time, the upper cavity, the upper cavity cover, and the lower cavity form a sealed space.

[0084] Vacuum is evacuated through the vacuum connector 416, and evacuation stops when the set vacuum level is reached. The actuator 411 of the upper copper mold assembly controls the upper copper mold assembly 410 to move downwards. At this time, the upper copper mold assembly 410 and the lower copper mold in the lower cavity 414 apply a certain pressure to the position of the second seal 704. The pressure is maintained for a certain time, and the heat sealing of the second seal position is completed. After heat sealing, the vacuum in the cavity is broken and returned to normal pressure. The upper cavity, upper copper mold assembly, upper cavity cover, and lower cavity are reset in sequence. The positioning groove clamp 402 carries the second-sealed soft-pack battery cell and slides to the initial position.

[0085] The material transfer process of the soft-pack battery cell from the secondary sealing module to the conveying module is as follows: After the secondary sealing process of the soft-pack battery cell is completed, the first suction cup assembly 303 slides linearly to the position groove clamp 402 and stops. The actuator of the first suction cup assembly 303 controls several suction cups of the first suction cup assembly to move straight down until the several suction cups of the first suction cup assembly contact the top of the soft-pack battery cell and continue to move down a short distance. The vacuum generator of the first suction cup assembly controls several suction cups of the first suction cup assembly to evacuate a vacuum. When the vacuum level reaches a set value, several suction cups of the first suction cup assembly hold the soft-pack battery cell and move straight up. After moving to the set distance, The servo module 302 controls the first suction cup assembly to move horizontally towards the conveying module 5. When it reaches the position of the conveying module, the actuator of the first suction cup assembly controls several suction cups of the first suction cup assembly to move linearly downward until the soft-pack battery cell is placed on the belt assembly. At this time, the vacuum generator of the first suction cup assembly controls several suction cups of the first suction cup assembly to break the vacuum. At this time, several suction cups of the first suction cup assembly no longer adhere to the soft-pack battery cell. The actuator of the first suction cup assembly controls the first suction cup assembly to move linearly upward back to the position before the first suction cup assembly completed the material transfer task. At this time, the material transfer process of the soft-pack battery cell from the second sealing module to the conveying module is completed.

[0086] In some implementations, such as Figure 11 As shown, the conveying module 5 includes: a belt assembly 501, including a belt and rollers; a plurality of fixed plates 502, one end of which is connected to the belt assembly 501 and the other end of which is connected to the equipment platform module 1; and a motor assembly 503, used to drive the movement of the belt assembly.

[0087] Specifically, several fixing plates 502 are fixed on the equipment platform 101, and the fixing plates 502 support the belt assembly 501; the motor assembly is composed of components such as a motor, a synchronous pulley, and a synchronous belt; the motor assembly provides power for the operation of the belt assembly 501.

[0088] The operation of the conveying module 5 is as follows: after the soft-pack battery cell is placed on the belt of the belt assembly 501 by the material transfer module 3, the motor assembly 503 drives the belt in the belt assembly 501 to run, and then the belt carries the soft-pack battery cell to the next device.

[0089] In some implementations, such as Figure 12 As shown, the human-machine interface module 6 includes: a fixed tube 601 and an operation screen 602. The operation screen 602 is provided at one end of the fixed tube 601 and the other end is connected to the equipment table module 1. The operation screen 602 is provided with an emergency stop switch 603 and a power switch 604.

[0090] In a preferred embodiment, the human-machine interface module 6 further includes an operation box 605, wherein the emergency stop switch 603 and the power switch 604 are not located on the operation screen; the operation screen 602, the emergency stop switch 603, and the power switch 604 are embedded in the operation box 605.

[0091] Specifically, the fixed pipe 601 is a round pipe, and the wiring of the human-machine interface module is embedded in the round pipe. The round pipe supports the operation box 605. The operation screen 602, the emergency stop switch 603, and the power switch 604 are embedded in the operation box 605. The operation screen 602 is responsible for setting the operation of each module and setting the operating program of each module. The emergency stop switch cuts off the main power supply of the entire device in an emergency. The power switch controls the power-off and power-on of the device.

[0092] In summary, the present invention provides a top-side sealing and second-side sealing integrated machine for solid-state batteries, comprising: a machine platform module, and a top-side sealing module, a material transfer module, a second-side sealing module, a conveying module, and a human-machine interface module disposed on the machine platform module; the top-side sealing module, the second-side sealing module, and the conveying module are arranged sequentially along the conveying direction of the material transfer module; the material transfer module is used to convey the pouch cells that have completed the top-side sealing process in the top-side sealing module to the second-side sealing module, and to convey the pouch cells that have completed the second-side sealing process in the second-side sealing module to the conveying module; the human-machine interface module is used to control the top-side sealing module, the material transfer module, the second-side sealing module, and the conveying module. Based on the characteristic that solid-state batteries do not require liquid injection, the present invention proposes a top-side sealing and second-side sealing integrated machine, which includes a top-side sealing module and a second-side sealing module to respectively realize the top-side sealing and second-side sealing processes of solid-state pouch batteries, and a material transfer module to realize the transfer of materials between different modules.
