Description

Technical Field

[0001] This invention relates to the field of solid-state battery technology, and more particularly to a solid-state battery pressurization device. Background Technology

[0002] Solid-state batteries are a battery technology that uses solid electrodes and solid electrolytes. Compared with traditional liquid or gel electrolyte batteries, they have advantages such as higher energy density, better safety, and longer service life. Solid-state batteries are pressurized by mechanical means, mainly by first pressurizing the solid-state battery and elastic materials. After that, shrink-type resin is filled and cured to form shrinkage pressure. Before pressurization, the performance of solid-state batteries is poor, while after pressurization, the gaps between solid-state battery materials are smaller, resulting in a larger contact area, lower internal resistance, and more charge and discharge cycles.

[0003] Existing patent CN117832738A discloses a solid-state battery pressurization device. It includes a pressurization bag and a fastening device. The pressurization bag is a flat bag made of flexible material, with a battery cell placed between adjacent pressurization bags. The pressurization bags and battery cells are arranged in layers and are in uniform contact with the battery cell surface. The fastening device is located on the outer side of the stacked pressurization bags and battery cells to limit the overall thickness of the device. This invention achieves full contact between the surface of the pressurization bag and the surface of the battery cell. The pressure-holding device adjusts the internal medium pressure and transmits the medium pressure to the pressurization bag through a pipeline, distributing it evenly across the flexible surface of the pressurization bag. This uniformly pressurizes the surface of the battery cell, ensuring uniform force distribution within the battery cell. The fastening device limits the overall thickness of the device, enhancing the pressurization effect and improving discharge efficiency.

[0004] While the above structure achieves a pressurizing effect, after pressurizing the solid-state battery, it becomes difficult to remove it from the mold due to its location inside the mold. This hinders the unloading of the solid-state battery. Furthermore, even with the use of a release agent, a small portion of the shrink-type resin will adhere to the mold after filling, making it difficult to move the solid-state battery during unloading. This makes rapid demolding difficult and may even damage the solid-state battery during movement, affecting its quality, reducing the pressurizing effect, and compromising its protection. This also reduces the unloading efficiency of the device, thereby lowering the overall pressurizing efficiency.

[0005] Therefore, how to provide a solid-state battery pressurization device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One object of the present invention is to provide a solid-state battery pressurization device. The solid-state battery pressurization device of the present invention includes a support frame, an end cap disposed on the support frame, a moving component disposed on the support frame, a pressurization component disposed on both the end cap and the moving component, a pushing component adapted to the end cap disposed on the support frame, an opening and closing component disposed on the pushing component, a pressurization space formed between the end cap, the opening and closing component and the moving component, an adjusting component disposed on the opening and closing component, a rolling component disposed between the adjusting component and the end cap, and the pushing component… The device is equipped with a lifting component connected to the adjusting component, a snap-fit ​​component, and a resin injection component on both the moving component and the opening / closing component. After the pressurizing component applies pressure, the moving component retracts, and the pushing component advances, forcing the opening / closing component to advance to form a first state, creating a relative displacement between the opening / closing component and the resin on the outside of the solid-state battery. The pushing component is then forced to advance further, forcing the opening / closing component to advance to form a second state, causing the opening / closing component to separate from the solid-state battery resin, thereby exposing the solid-state battery.

[0007] Preferably, the moving component includes an electric push rod disposed on the support frame, the output end of the electric push rod is provided with a connecting block, and the connecting block is provided with a sealing cover adapted to the end cover.

[0008] Preferably, the pressurizing assembly includes a pressurizing cylinder disposed on the support frame, a pressurizing piston disposed inside the pressurizing cylinder, a pressurizing rod disposed on the pressurizing piston that penetrates the pressurizing cylinder or the end cover, a pressurizing block disposed on the pressurizing rod, and a connecting pipe disposed on the pressurizing cylinder.

[0009] Preferably, the pushing component includes a hydraulic push rod disposed on the support frame, the output end of the hydraulic push rod is provided with a pushing block, and the pushing block is provided with a support frame sleeved on the outer ring of the end cap.

[0010] Preferably, the opening and closing assembly includes a support block disposed on the support frame, a shaft is connected to the support block by a bearing, an opening and closing rod is fixedly sleeved on the shaft, and an opening and closing plate is hinged to the opening and closing rod.

[0011] Preferably, the adjustment assembly includes a fixed block disposed on the support block, an adjustment rod one hinged to the fixed block, an adjustment rod two disposed on the adjustment rod one, and the adjustment rod two hinged to the opening and closing rod.

[0012] Preferably, the rolling assembly includes a roller mounted on the adjusting rod, and the end cover is provided with an arc-shaped track adapted to the roller, the roller passing through the end cover and the arc-shaped track.

[0013] Preferably, the lifting assembly includes a support outer rod hinged to the support frame, an adjusting rod hinged to a stop block, a support inner rod passing through the support outer rod on the stop block, and a lifting spring sleeved on the outer ring of the support inner rod between the support outer rod and the stop block.

[0014] Preferably, the snap-fit ​​assembly includes a guide plate disposed on the support block, a snap-fit ​​rod passing through the guide plate, a pin disposed on the snap-fit ​​rod, a snap-fit ​​spring sleeved on the outer ring of the snap-fit ​​rod between the pin and the guide plate, and a snap-fit ​​gear adapted to the pin fixedly sleeved on the shaft.

[0015] Preferably, the injection assembly includes an injection tube disposed on the pressurizing block, the injection tube penetrating the sealing cap, a guide groove being formed on the pressurizing block, and a filling groove for filling resin being formed on the opening and closing plate.

[0016] The beneficial effects of this invention are as follows:

[0017] In use, the solid-state battery and the elastic material are sequentially connected and placed inside the opening and closing assembly. The moving assembly is then activated, causing it to come into contact with the opening and closing assembly, forcing the end cap, opening and closing assembly, and moving assembly to form a pressurized environment. During pressurization, the pressurizing assembly is activated, forcing it to pressurize multiple solid-state batteries and the elastic material, causing the elastic material to compress and generate rebound force. Once the pressurizing assembly has achieved adequate pressure, a shrinkable resin is introduced into the interior through the injection assembly, causing the shrinkable resin to wrap around the outer ring of the pressurized solid-state battery until the resin cures and generates shrinkage pressure; pressurization is then complete. Next, the solid-state battery, elastic material, and shrinkable resin need to be removed. The moving component is then activated in reverse to move it away from the solid-state battery, creating space for the opening and closing component to move. At this point, the pressure component clamps the solid-state battery. During demolding, the pushing component is activated, causing the opening and closing component to move in its first state. Under the limiting action of the lifting component, adjusting component, and rolling component, the opening and closing component moves horizontally along the end cap, causing relative displacement between the opening and closing component and the resin on the outside of the solid-state battery, resulting in the separation of the opening and closing component from a small portion of the resin. The pushing component continues to move forward. The movement causes the pushing component to drive the opening and closing component to form a second state of movement. The adjusting component and the opening and closing component drive the rolling component to move forward. Under the lifting action of the lifting component, the rolling component is forced to drive the adjusting component to move and adjust, which in turn forces the opening and closing component to move, causing the opening and closing component to rotate and open. At the same time, the locking component forms a locking mechanism, forcing multiple opening and closing components to move away from the solid-state battery simultaneously, exposing the solid-state battery covered by resin. The solid-state battery is picked up using a tool, and the solid-state battery is released using the pressurizing component, realizing the unloading operation of the pressurized solid-state battery. In summary, the solid-state battery pressurizing device of this application can effectively combine the pressurization of the solid-state battery with the shrinkage pressure formed by the curing of shrink-type resin, which greatly improves the performance of the solid-state battery. After pressurization is completed, the device can quickly demold using various form changes, reducing the adhesion between the resin and the mold, so that the pressurized solid-state battery is fully exposed, which facilitates the unloading operation of the solid-state battery, avoids damage to the solid-state battery, improves the quality of the solid-state battery, improves the pressurization effect, helps protect the solid-state battery, improves the unloading efficiency of the device, and thus improves the overall pressurization efficiency of the solid-state battery.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0031] Example 1:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes a support frame 1, an end cap 2 disposed on the support frame 1, a moving component 3 disposed on the support frame 1, a pressurization component 4 disposed on both the end cap 2 and the moving component 3, a pushing component 5 adapted to the end cap 2 disposed on the support frame 1, an opening and closing component 6 disposed on the pushing component 5, a pressurization space is formed between the end cap 2, the opening and closing component 6 and the moving component 3, an adjusting component 7 disposed on the opening and closing component 6, a rolling component 8 disposed between the adjusting component 7 and the end cap 2, and a component 8 disposed on the pushing component 5 that interacts with the adjusting component 7. The connecting lifting component 9 and the opening and closing component 6 are provided with a snap-fit ​​component 10. The moving component 3 and the opening and closing component 6 are provided with a resin injection component 11. After the pressurizing component 4 pressurizes, the moving component 3 is moved backward, the pushing component 5 is pushed forward, and the opening and closing component 6 is forced to move forward to form a first state, so that the opening and closing component 6 and the resin on the outside of the solid battery are relatively displaced. The pushing component 5 is forced to move forward further, and the opening and closing component 6 is forced to move forward to form a second state, so that the opening and closing component 6 and the solid battery resin are separated, thereby exposing the solid battery.

[0033] Working principle: In use, the solid-state battery and the elastic material are connected sequentially and placed inside the opening and closing assembly 6. The moving assembly 3 is activated, causing it to fit against the opening and closing assembly 6, forcing the end cap 2, the opening and closing assembly 6, and the moving assembly 3 to form a pressurized environment. During pressurization, the pressurizing assembly 4 is activated, forcing it to pressurize multiple solid-state batteries and the elastic material, causing the elastic material to compress and generate rebound force. Once the pressurizing assembly 4 has achieved adequate pressure, shrink-type resin is introduced into the interior through the injection assembly 11, causing the shrink-type resin to wrap around the outer ring of the pressurized solid-state battery until the resin cures and generates shrinkage pressure. After pressing, the solid-state battery, elastic material, and shrinkable resin need to be removed. The moving component 3 is then reversed and moved away from the solid-state battery, creating space for the opening / closing component 6 to move. At this time, the pressurizing component 4 clamps the solid-state battery. During demolding, the pushing component 5 is activated, causing the opening / closing component 6 to move in its first state. Under the limiting action of the lifting component 9, adjusting component 7, and rolling component 8, the opening / closing component 6 moves horizontally along the end cap 2, causing relative displacement between the opening / closing component 6 and the resin on the outside of the solid-state battery, separating the opening / closing component 6 from a small portion of the resin. Component 5 continues its forward movement, causing the pushing component 5 to drive the opening and closing component 6 into a second state of motion. The adjusting component 7 and the opening and closing component 6 drive the rolling component 8 forward. Under the pushing action of the lifting component 9, the rolling component 8 is forced to drive the adjusting component 7 to adjust its movement, which in turn forces the adjusting component 7 to move the opening and closing component 6, causing the opening and closing component 6 to rotate and open. At the same time, the locking component 10 forms a locking mechanism, forcing multiple opening and closing components 6 to move away from the solid-state battery simultaneously, exposing the resin-coated solid-state battery. The solid-state battery is then picked up using a tool, and the pressurizing component 4 is used to release the solid-state battery, thus achieving the pressurized... Solid-state battery unloading operation; In summary, the solid-state battery pressurization device of this application can effectively combine the pressurization of the solid-state battery with the shrinkage pressure formed by the curing of shrink-type resin, which greatly improves the performance of the solid-state battery. After pressurization is completed, the device can quickly demold by changing its various forms, reducing the adhesion between the resin and the mold, so that the pressurized solid-state battery is fully exposed, which facilitates the unloading operation of the solid-state battery, avoids damage to the solid-state battery, improves the quality of the solid-state battery, improves the pressurization effect, helps protect the solid-state battery, improves the unloading efficiency of the device, and thus improves the overall pressurization efficiency of the solid-state battery.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes a moving component 3 comprising an electric push rod 301 mounted on a support frame 1, a connecting block 302 mounted on the output end of the electric push rod 301, and a sealing cover 303 adapted to the end cover 2 mounted on the connecting block 302.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes a pressurization component 4 comprising a pressurization cylinder 401 disposed on a support frame 1, a pressurization piston disposed inside the pressurization cylinder 401, a pressurization rod 402 disposed on the pressurization piston and penetrating the pressurization cylinder 401 or the end cap 2, a pressurization block 403 disposed on the pressurization rod 402, and a connecting pipe 404 disposed on the pressurization cylinder 401.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes an opening and closing component 6 comprising a support block 601 disposed on a support frame 503, a shaft 602 connected to the support block 601 by a bearing, an opening and closing rod 603 fixedly sleeved on the shaft 602, and an opening and closing plate 604 hinged to the opening and closing rod 603.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes an adjustment component 7 comprising a fixed block 701 disposed on a support block 601, an adjustment rod 702 hinged to the fixed block 701, an adjustment rod 703 disposed on the adjustment rod 702, and the adjustment rod 703 hinged to the opening and closing rod 603.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes a rolling assembly 8 comprising a roller 801 mounted on an adjusting rod 702, and an arc-shaped track 802 adapted to the roller 801 on the end cover 2, wherein the roller 801 passes through the end cover 2 and the arc-shaped track 802.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes a lifting assembly 9 comprising a supporting outer rod 901 hinged to a support frame 503, an adjusting rod 702 hinged to a stop block 902, a supporting inner rod 903 passing through the supporting outer rod 901 on the stop block 902, and a lifting spring 904 sleeved on the outer ring of the supporting inner rod 903 between the supporting outer rod 901 and the stop block 902.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, a solid-state battery pressurization device of the present invention includes a snap-fit ​​assembly 10 comprising a guide plate 1001 disposed on a support block 601, a snap-fit ​​rod 1002 disposed on the guide plate 1001 and passing through the guide plate 1001, a pin 1003 disposed on the snap-fit ​​rod 1002, a snap-fit ​​spring 1004 disposed between the pin 1003 and the guide plate 1001 and sleeved on the outer ring of the snap-fit ​​rod 1002, and a snap-fit ​​gear 1005 adapted to the pin 1003 fixedly sleeved on the shaft 602.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a solid-state battery pressurization device of the present invention includes an injection component 11 comprising an injection pipe 1101 disposed on a pressurization block 403, the injection pipe 1101 penetrating a sealing cover 303, a guide groove 1102 formed on the pressurization block 403, and a filling groove 1103 for filling resin formed on the opening and closing plate 604.

[0044] Working principle: In use, the solid-state battery and the elastic material are connected in sequence and placed into the opening and closing plate 604, so that the solid-state battery corresponds to the filling groove 1103. The electric push rod 301 is activated, and the output end of the electric push rod 301 drives the connecting block 302 and the closing cover 303 to move. At the same time, the pressure cylinder 401 is pressurized appropriately, so that the closing cover 303 moves synchronously with the pressure rod 402 and the pressure block 403 until the closing cover 303 is in contact with the opening and closing plate 604. At this time, a pressurized environment is formed between the end cover 2, the opening and closing plate 604 and the closing cover 303. During pressurization, the pressure cylinders 401 on both sides are pressurized synchronously and appropriately through the connecting pipe 404, so that the hydraulic oil drives the pressure piston to move, forcing the pressure piston to move. The plug drives the pressure rod 402 to move, and the pressure rod 402 drives the pressure block 403 to move forward, so that the pressure blocks 403 on both sides simultaneously pressurize multiple solid batteries and elastic materials, causing the elastic materials to compress and generate rebound force. After the pressure block 403 applies reasonable pressure to the solid battery, the resin delivery system is connected through the injection pipe 1101 to inject resin into the guide groove 1102. The guide groove 1102 guides the resin to the filling groove 1103, so that the resin wraps around and covers the outer ring of the solid battery. Through heating or cooling treatment, the resin and solid battery become one, realizing the curing effect of shrinkage resin, generating shrinkage pressure, which, combined with the rebound effect of the elastic material, achieves a bidirectional pressurization effect.

[0045] After pressurization is completed, the solid-state battery, elastic material and shrink-type resin need to be removed. The electric push rod 301 is started in reverse. The output end of the electric push rod 301 drives the connecting block 302 to retract, so that the connecting block 302 drives the sealing cover 303 to retract. The sealing cover 303 moves back along the pressurization rod 402 and the injection tube 1101, so that the sealing cover 303 is away from the pressurized solid-state battery, leaving space for the movement of the opening and closing plate 604. At this time, the pressurization blocks 403 on both sides form a clamping effect on the solid-state battery.

[0046] During demolding, the hydraulic push rod 501 is activated. The output end of the hydraulic push rod 501 drives the push block 502 to move, which in turn drives the support frame 503 to move. This causes the support frame 503 to move the support block 601 to the first state of motion. The support block 601 then drives the shaft 602, the opening / closing rod 603, and the opening / closing plate 604 to move. This causes relative displacement between the inner wall of the opening / closing plate 604 and the resin on the outside of the solid-state battery, reducing the separation of the resin from the solid-state battery and ensuring that the resin coats the solid-state battery. Under the action of the molding agent, the opening and closing plate 604 separates from a small part of the resin. During this process, due to the restriction of the end cap 2, the roller 801 moves horizontally in a straight line, so that the adjusting rod 702 does not rotate around the hinge point. When the support frame 503 moves in a straight line, the support frame 503 drives the support block 601, adjusting rod 702, adjusting rod 703, opening and closing rod 603, snap-fit ​​assembly 10 and lifting assembly 9 to move. The adjusting rod 702 drives the roller 801 to move along the end cap 2.

[0047] The hydraulic push rod 501 continues to move forward, and its output end continues to drive the push block 502 and support frame 503 to move forward, forcing the support frame 503 to drive the support block 601 to form a second state of movement. At this time, the roller 801 rolls onto the arc track 802 and moves forward along the arc track 802. Under the action of the lifting spring 904, the inner support rod 903 moves within the outer support rod 901. The inner support rod 903 drives the stop block 902 to move, and the stop block 902 drives the adjusting rod 1 702 to rotate upward around the hinge point. The adjusting rod 1 702 drives the adjusting rod 2 703 to rotate as well, causing the adjusting rod 2 703 to drive the opening and closing rod 603 to rotate, causing the shaft 602 to rotate. The rotation of the shaft 602 drives the locking gear 1005 to rotate, causing the locking gear 1005 to separate from the pin 1003. The pin 1003 then engages the locking mechanism. Rod 1002 moves on guide plate 1001, and locking spring 1004 is compressed. When locking gear 1005 rotates one tooth, locking gear 1005 meshes with pin 1003 again, thereby achieving intermittent locking effect on shaft 602, preventing opening and closing rod 603 and shaft 602 from rotating freely, until opening and closing rod 603 drives opening and closing plate 604 to move to a reasonable angle, so that opening and closing plate 604 forms a rotating open state, forcing multiple opening and closing plates 604 to move away from solid battery at the same time, so that solid battery covered by resin is completely exposed. Solid battery is picked up with tools, and hydraulic oil in pressurizing cylinder 401 is discharged through connecting pipe 404, so that pressurizing piston drives pressurizing rod 402 to retract, so that pressurizing rod 402 drives pressurizing block 403 to retract, so that pressurizing block 403 releases solid battery, realizing the unloading operation of pressurized solid battery;

[0048] Similarly, during loading, tools are used to place the solid-state battery and elastic material at positions corresponding to the opening and closing plate 604. The solid-state battery is clamped using the pressure cylinders 401 and pressure blocks 403 on both sides. The tools are released, and the hydraulic push rod 501 is activated in the reverse direction. This causes the output end of the hydraulic push rod 501 to drive the push block 502 and support frame 503 to retract, causing the roller 801 to move from the arc track 802 to the end cover 2. That is, the opening and closing plate 604 moves from the second state to the first state. Under the action of the lifting assembly 9, the adjusting rod 1 702 and adjusting rod 2 703 rotate, causing the adjusting rod 2 703 to drive the opening and closing rod 603 and the opening and closing plate 604 closer to the solid-state battery until the opening and closing plate 604 is in contact with the solid-state battery. At this point, the locking assembly 10 and the lifting assembly... Component 9 returns to its original state, and hydraulic push rod 501 continues to move in the opposite direction. Under the limiting action of roller 801, support frame 503 drives support block 601, opening and closing rod 603, opening and closing plate 604, adjusting rod one 702, adjusting rod two 703, snap-fit ​​component 10 and lifting component 9 to move back. Adjusting rod one 702 drives roller 801 to move back in a straight line along end cover 2 until end cover 2 is in contact with opening and closing plate 604. Electric push rod 301 is activated. The output end of electric push rod 301 drives connecting block 302 and sealing cover 303 to move forward until sealing cover 303 is in contact with opening and closing plate 604, thereby creating a pressurized environment for end cover 2, opening and closing plate 604 and sealing cover 303. The above operation is repeated to complete the pressurization operation of multiple solid-state batteries.

[0049] This solution effectively combines the pressurization of solid-state batteries with the shrinkage pressure generated by the curing of shrink-type resin, greatly improving the performance of solid-state batteries. Furthermore, after pressurization, the device's various configurations enable rapid demolding, reducing resin adhesion to the mold and fully exposing the pressurized solid-state battery. This facilitates unloading, prevents damage, improves battery quality, enhances pressurization, protects the battery, and increases the device's loading and unloading efficiency, thereby improving the overall pressurization efficiency of the solid-state batteries.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
