[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] In related technologies, during the electrolyte injection process of power prismatic batteries, the battery casing needs to undergo positive and negative pressure circulation according to process requirements. Under the action of positive and negative pressure, the surface of the battery casing will contract or expand back and forth, which can easily lead to unevenness on the battery surface. Usually, the restraint plates of the battery restraint clamp are used to restrain and press the sides of the battery, but this cannot solve the problem of unevenness on the surface of the battery casing due to expansion under negative pressure.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in order to solve the above-mentioned technical problems, this application provides a restraint plate 100, which includes a restraint plate 110. The restraint plate 110 has a front side 113 and a vacuum port 112. The front side 113 has at least one vacuum adsorption hole 114, which is distributed throughout the entire front side 113 and is connected to the vacuum port 112. The vacuum port 112 is away from the front side 113. The front side 113 is used to abut against the side of the battery 300 casing, so that the side of the battery 300 casing can seal all the vacuum adsorption holes 114.

[0046] In these embodiments, typically, the side surface of the battery 300 casing is flat, and the front surface 113 of the corresponding restraint plate 110 is used to abut against the side surface of the battery 300 casing. That is, the restraint plate 110 and the side surface of the battery 300 casing are parallel, ensuring that they are in surface-to-surface contact, increasing the contact area, and facilitating the sealing of the vacuum adsorption hole 114 through the side surface of the battery 300 casing, so that the vacuum adsorption hole 114 is in a negative pressure environment, thereby generating an adsorption force on the side surface of the battery 300 casing.

[0047] Obviously, by distributing the vacuum adsorption holes 114 across the entire front side 113, the adsorption force on the side of the battery 300 casing can be increased, and most of the side area of ​​the battery 300 casing can be adsorbed.

[0048] For example, the number of vacuum adsorption holes 114 is one. The opening of the vacuum adsorption hole 114 extends along a predetermined path on the front surface 113 of the restraint plate 110, so that the openings of the vacuum adsorption hole 114 can be distributed on the front surface 113 of the restraint plate 110. For example, the vacuum adsorption hole 114 includes multiple horizontal segments 1141 and multiple vertical segments 1142. The horizontal segments 1141 are parallel to the width direction of the front surface 113 of the restraint plate 110, and the vertical segments 1142 are parallel to the length direction of the front surface 113 of the restraint plate 110. The multiple vertical segments 1142 are spaced apart in the width direction of the restraint plate 110, and the multiple horizontal segments 1141 are spaced apart in the length direction of the restraint plate 110. The vertical segments 1142 and the horizontal segments 1141 are intersecting and connected. This arrangement is beneficial to the uniformity of vacuum degree at all points of the vacuum adsorption hole 114.

[0049] Of course, in other embodiments, there are multiple vacuum adsorption holes 114, which are distributed on the front side 113 of the restraint plate 110. While ensuring that all vacuum adsorption holes 114 are connected to the vacuum port 112, a negative pressure environment is created at the vacuum adsorption holes 114 by drawing negative pressure into the vacuum port 112. The number of vacuum adsorption holes 114 can be two, three, four, five, six, seven, or eight, etc.

[0050] This application addresses the surface flatness issue of the battery 300 during positive and negative pressure breathing processes. By providing vacuum adsorption holes 114 on the restraint plate 110 and connecting it to an external vacuum system via a vacuum port 112, a uniform adsorption force can be applied to the sides of the battery 300 when it is under negative pressure, effectively reducing surface deformation caused by internal pressure changes. Simultaneously, when the battery 300 is under positive pressure, the restraint plate 110 can also apply pressure to the sides of the battery 300 to prevent excessive expansion. Clearly, this design not only improves the quality and efficiency of the battery 300 manufacturing process but may also extend its lifespan by reducing deformation of the battery casing caused by repeated pressure changes, thus helping to maintain the stability and sealing of the battery 300 structure.

[0051] Of course, in the implementation of this technology, the following points should be noted: the restraint plate 110 and its related components need to be made of corrosion-resistant and high-temperature-resistant materials to adapt to the battery 300 production environment. The sealing between the restraint plate 110 and the battery 300 must be maintained to prevent leakage during the vacuuming process. The design parameters of the restraint plate 110, such as the size, number, and distribution of the vacuum adsorption holes 114, should be appropriately adjusted according to different battery 300 models and sizes.

[0052] like Figure 1 As shown, in some embodiments, the number of vacuum adsorption holes 114 is one, the front surface 113 of the restraint plate 110 has a groove, the groove is connected to the vacuum port 112, the groove is distributed throughout the front surface 113 of the restraint plate 110, and the groove opening is located on the front surface 113, so that the groove opening forms a vacuum adsorption hole 114.

[0053] In these embodiments, the restraint plate 110 has an elongated vacuum adsorption hole 114, which is actually achieved through a groove. Compared to a design with multiple small holes, a single large hole (achieved through a groove) can more effectively cover the surface of the battery 300, providing a more uniform adsorption force and helping to better maintain the flatness of the surface of the battery 300.

[0054] Furthermore, the trench design reduces processing steps on the restraint plate 110, such as drilling, thereby simplifying the manufacturing process and reducing costs. It should be noted that the trench design can be flexibly adjusted according to the specific size and shape of the battery 300, for example, by changing the width, depth, and layout of the trenches to accommodate different types of batteries 300. The trench layout needs careful design to ensure uniform adsorption force across the entire surface of the battery 300. An unreasonable trench distribution will result in uneven adsorption force, affecting the flatness of the battery 300 surface.

[0055] For example, the depth of the trench gradually decreases in the direction of gas flow, which helps to control the uniformity of gas pressure throughout the trench.

[0056] like Figure 4 As shown, in some embodiments, the restraint plate 100 further includes a sealing plate 120, which is disposed on the front side 113. The sealing plate 120 has a plurality of through holes 121, which are distributed on the sealing plate 120 and are connected to the vacuum adsorption holes 114.

[0057] In these embodiments, the restraint plate 100 incorporates a sealing plate 120, which further enhances the system's reliability and functionality. Specifically, the sealing plate 120 fills the minute gaps between the restraint plate 110 and the surface of the battery 300, ensuring no air leakage occurs during vacuuming and thus improving the vacuum adsorption effect. In other words, the sealing plate 120 allows for a tighter fit to the surface of the battery 300, effectively sealing even if the battery 300 surface has slight unevenness.

[0058] The sealing plate 120 is typically made of a soft material, which reduces the direct pressure of the restraint plate 110 on the surface of the battery 300, preventing scratches or damage to the battery 300 casing. The soft sealing plate 120 can also absorb some mechanical stress, reducing stress concentration in the battery 300 during positive and negative pressure cycles, and extending the service life of the battery 300.

[0059] The multiple through holes 121 on the sealing plate 120 are connected to the vacuum adsorption holes 114 on the restraint plate 110, which can distribute the adsorption force more evenly, ensuring that the adsorption force on all parts of the battery 300 surface is consistent, and further improving the surface flatness. It can also increase the contact area between the restraint plate 110 and the side of the battery 300 casing, so that when the battery 300 casing is in an expanded state, the restraint plate 110 can be used to compress the battery 300 casing.

[0060] For example, the sealing plate 120 is made of materials such as silicone rubber and EPDM (ethylene propylene diene monomer rubber). These materials not only provide a good sealing effect, but also withstand various chemical substances and temperature changes encountered during the production of battery 300.

[0061] The through holes 121 should be evenly distributed on the sealing plate 120, corresponding to the positions of the vacuum adsorption holes 114 on the restraint plate 110, to ensure that each adsorption point can work effectively. The diameter and spacing of the through holes 121 need to be optimized according to the specific size and shape of the battery 300 to achieve the best adsorption effect.

[0062] For example, the sealing plate 120 can be fixed to the front side 113 of the restraint plate 110 by adhesive, snap-on or other means to ensure that it will not shift or fall off during use.

[0063] In some embodiments, the sealing plate 120 is an elastic sealing plate 120 or a flexible sealing plate 120.

[0064] In these embodiments, the resilient sealing plate 120 is typically made of a material with good elasticity, such as silicone rubber, nitrile rubber (NBR), fluororubber (FPM), etc. These materials can deform under pressure and quickly return to their original shape after the pressure is released. The elastic material can better fill the tiny gaps between the restraint plate 110 and the surface of the battery 300, ensuring no air leakage during vacuuming.

[0065] The flexible sealing plate 120 is typically made of a soft and resilient material, such as polyurethane (PU) or TPU (thermoplastic polyurethane). These materials can deform under pressure, but their recovery speed after deformation is relatively slow. Flexible materials can better conform to the shape of the battery 300 surface, allowing for a tight fit even on surfaces with significant unevenness. The flexible material exerts less contact pressure on the battery 300 surface, effectively preventing scratches or damage to the battery 300 casing.

[0066] like Figure 4 As shown, in some embodiments, this application also provides a restraint assembly 10, which includes a restraint plate 100 and a drive member 200 as described in any of the above embodiments. The drive member 200 is connected to the restraint plate 110 of the restraint plate 100, and the drive member 200 is used to drive the restraint plate 110 to move along a first preset direction. The first preset direction is perpendicular to the front face 113.

[0067] In these embodiments, the restraint assembly 10 includes not only the aforementioned restraint plate 100, but also a driving member 200. The driving member 200 is connected to the restraint plate 110 and drives the restraint plate 110 to move along a first preset direction to approach or move away from the side of the battery 300 casing. That is, when the battery 300 is filled with electrolyte, the driving member 200 drives the restraint plate 110 towards the side of the battery 300 casing until it makes contact, and the sealing between the two is ensured by adjusting the pressure. For example, the first preset direction is perpendicular to the front face 113 of the restraint plate 110. The driving member 200 can automatically adjust the position of the restraint plate 110 according to the size and position of the battery 300, ensuring that the restraint plate 110 always fits tightly against the side of the battery 300. This automatic adjustment function can adapt to batteries 300 of different sizes, improving the versatility and flexibility of the system.

[0068] It should be noted that the drive unit 200 can precisely control the pressure applied by the restraint plate 110 to the side of the battery 300, avoiding excessive pressure that could cause deformation or damage to the battery 300. During positive and negative pressure breathing, the deformation of the battery 300 can be better controlled by adjusting the position and pressure of the restraint plate 110.

[0069] The automated drive unit 200 reduces manual intervention and improves production efficiency and consistency. Through programmable control, standardized operations can be achieved during mass production, ensuring that every battery 300 receives the same treatment.

[0070] There are several options for the type of drive element 200. For example, an electric linear actuator, a pneumatic cylinder, or a hydraulic cylinder can be selected as the drive element 200. Electric linear actuators are suitable for applications requiring high precision, enabling accurate position control. Pneumatic and hydraulic cylinders are suitable for applications requiring greater thrust, providing stable driving force.

[0071] Typically, the drive unit 200 is connected to a control system (such as a PLC or computer) to control the movement of the restraint plate 110 via a program. The control system can automatically adjust the position and pressure of the restraint plate 110 according to the size and process requirements of the battery 300. Alternatively, position and pressure sensors can be added to the restraint assembly 10 to monitor the position of the restraint plate 110 and the pressure applied to the battery 300 in real time. Clearly, through a feedback mechanism, the action of the drive unit 200 can be adjusted promptly, ensuring the stability and reliability of the system.

[0072] like Figure 4 As shown, in some embodiments, the drive member 200 includes a bladder 210 connected to the back surface 115 of the restraint plate 110; wherein the bladder 210 has an inlet and outlet for fluid to enter and exit the bladder 210, such that the bladder 210 can switch between at least an inflated state and a contracted state, in which the front surface 113 of the restraint plate 110 presses against the side surface of the battery 300 housing; in which the contracted state, the restraint plate 110 and the side surface of the battery 300 housing are spaced apart.

[0073] In these embodiments, the drive unit 200 employs a capsule 210 design, an innovative and efficient solution. The capsule 210 moves the restraint plate 110 by filling and discharging fluid (such as air or liquid), thereby better adapting to the needs of the battery 300 during positive and negative pressure breathing processes.

[0074] The capsule 210 is an expandable and contractible elastic container, typically made of corrosion-resistant and high-pressure-resistant materials, such as rubber or special synthetic materials. The capsule 210 is connected to the back surface 115 of the restraint plate 110, ensuring that the expansion and contraction of the capsule 210 directly drives the movement of the restraint plate 110 in a first predetermined direction. The capsule 210 has inlets and outlets for fluid to enter and exit. These inlets and outlets are typically connected to a fluid control system, such as an air pump or hydraulic pump, for fluid delivery and recovery via pipelines.

[0075] In the expansion state: when fluid (such as air or liquid) enters the bladder 210 through the inlet and outlet, the bladder 210 expands, pushing the restraint plate 110 to move toward the side of the battery 300 casing, so that the front 113 of the restraint plate 110 is tightly attached to the battery 300 casing, and a uniform pressure is applied to the side of the battery 300.

[0076] Contraction state: When fluid is discharged from the bladder 210, the bladder 210 contracts, and the restraint plate 110 moves away from the battery 300 casing, so that the restraint plate 110 and the side of the battery 300 casing maintain a certain distance, thereby releasing the restraint on the battery 300.

[0077] Clearly, by controlling the flow rate and pressure of the fluid, the expansion and contraction of the capsule 210 can be precisely adjusted, thereby achieving fine control over the position of the restraint plate 110. This precise control capability allows the system to adapt to batteries 300 of different sizes and shapes, improving the system's versatility and flexibility. Furthermore, the expansion of the capsule 210 provides a uniform pressure distribution, ensuring that the pressure of the restraint plate 110 on the sides of the battery 300 is uniform and consistent, preventing excessive local pressure that could lead to deformation or damage to the battery 300. The uniform pressure distribution facilitates the adaptive adjustment of the restraint plate 110 according to the sides of the battery 300's casing, helping to improve the flatness of the battery 300's surface and reduce unevenness.

[0078] Furthermore, the structure of the capsule 210 drive component 200 is relatively simple, easy to install and maintain, and has a low cost. Compared with traditional drive methods such as electric actuators or cylinders, the capsule 210 drive component 200 has a lower failure rate and lower maintenance costs. In addition, the capsule 210 has elastic deformation capability, which has a buffering effect and avoids impact or compression damage to the battery 300.

[0079] For example, the capsule 210 should be made of a material that is corrosion-resistant, pressure-resistant, and temperature-resistant, such as special rubber or synthetic material.

[0080] The fluid control system should include an air pump or hydraulic pump, pipelines, valves, and controllers. The controller can be a PLC or a computer, which is programmed to precisely control the expansion and contraction of the bladder 210. Pressure sensors and position sensors can be installed on the bladder 210 and the restraint plate 110 to monitor the expansion status of the bladder 210 and the position of the restraint plate 110 in real time. Through a feedback mechanism, the fluid supply can be adjusted in a timely manner to ensure the stability and reliability of the system.

[0081] For example, valve cores are installed at the inlet and outlet. The main function of the valve cores is to inflate and maintain the airtightness of the bladder 210. When air is inflated into the bladder 210 through the valve core, the force of the increased air inside the bladder 210 due to the pressure difference causes the bladder 210 to elongate, clamping the battery 300 and stopping the inflation. During normal rest, the gas-chemical reaction inside the battery 300 plays a restraining role in preventing the battery 300 from expanding. Before removing the battery 300, the pressure in the bladder 210 is first released through the valve core, and the bladder 210 retracts.

[0082] like Figure 4 As shown, in some embodiments, the drive member 200 includes a mounting base, the bladder 210 has opposite ends, one end of the bladder 210 is connected to the mounting base, and the other end of the bladder 210 is connected to the back surface 115 of the restraint plate 110.

[0083] In these embodiments, the drive element 200 includes not only the capsule 210 but also a mounting base. The capsule 210 has two opposing ends, one end of which is connected to the mounting base, and the other end is connected to the back surface 115 of the restraint plate 110. The mounting base is a fixed support structure, typically mounted on the frame of the device, for securing one end of the capsule 210. The mounting base ensures that the capsule 210 has a stable fulcrum during expansion and contraction, thereby allowing for more precise control of the movement of the restraint plate 110.

[0084] Clearly, the mounting base provides a fixed fulcrum for the bladder 210, ensuring its stable operation during expansion and contraction. This stable fulcrum contributes to improving the service life and reliability of the bladder 210.

[0085] For example, the connection between the bladder 210 and the mounting base can be achieved through threaded connection, snap-fit ​​connection, or adhesive bonding, ensuring a secure and airtight connection. The connection should be sealed to prevent fluid leakage.

[0086] For example, the connection between the capsule 210 and the restraint plate 110 can be achieved using bolts, clips, or adhesive bonding to ensure a strong and stable connection. Similarly, the connection should be sealed to prevent fluid leakage.

[0087] like Figure 4 As shown, in some embodiments, at least one of the mounting base and restraint plate 110 is provided with a drain port 111, which is connected to the inlet and outlet of the bladder body 210.

[0088] In these embodiments, the following situations exist:

[0089] The first scenario: The mounting base is equipped with a drain port 111, which is connected to the inlet and outlet of the bladder body 210 via a pipe.

[0090] The second scenario: The restraint plate 110 is equipped with a drain port 111, which is connected to the inlet and outlet of the bladder 210 through a pipe.

[0091] The third scenario: Both the mounting base and the restraint plate 110 are equipped with exhaust ports 111, which are connected to the inlet and outlet of the bladder body 210 via pipes.

[0092] Any of the above methods can achieve the filling and emptying of fluid in the capsule 210. The inclusion of extraction / extraction ports 111 on both the mounting base and the restraint plate 110 provides multiple redundancies, improving the system's reliability and flexibility.

[0093] Furthermore, the design of multiple exhaust ports 111 provides more control points, further improving the accuracy and reliability of the system. The exhaust ports 111 on the mounting base and restraint plate 110 provide multiple redundancies, ensuring that even if one exhaust port 111 fails, another exhaust port 111 can continue to operate, ensuring the stability and reliability of the system. The design of multiple exhaust ports 111 can also reduce fluid flow resistance and improve fluid transfer efficiency.

[0094] For example, the exhaust port 111 can be connected to the pipeline by means of quick-connect fittings, threaded fittings, or welding to ensure a secure and airtight connection. The connection should be sealed to prevent fluid leakage.

[0095] like Figure 4 As shown, in some embodiments, the restraint plate 110 is provided with a drain port 111, and the two opposite ends of the bladder 210 are provided with inlets and outlets. One of the inlets and outlets is connected to the drain port 111 on the restraint plate 110, and the mounting base is used to block the other inlet and outlet.

[0096] In these embodiments, the restraint plate 110 is provided with an exhaust port 111 for fluid to enter and exit the bladder 210. The exhaust port 111 is connected to a fluid control system, such as an air pump or a hydraulic pump, via a pipe. Both ends of the bladder 210 are provided with inlets and outlets. One inlet / outlet communicates with the exhaust port 111 on the restraint plate 110, and the other inlet / outlet is blocked by a mounting base. The mounting base is used to secure one end of the bladder 210 and block one of the inlets / outlets. The mounting base is typically mounted on the frame of the device, providing a stable support.

[0097] For example, the capsule 210 is configured as a corrugated rubber tube. Of course, in other embodiments, the capsule 210 is configured as a flexible rubber tube.

[0098] like Figure 6As shown, in some embodiments, this application also provides a battery 300 restraint clamp, which includes a restraint component 10 as described in any of the above embodiments and a carrier 400. The carrier 400 has a second preset direction, and the first preset direction and the second preset direction are arranged parallel to each other. The carrier 400 is provided with at least a plurality of restraint components 10, and the plurality of restraint components 10 are arranged sequentially in the second preset direction. The number of restraint components 10 in each group is two, and each group of restraint components 10 is arranged opposite to each other. The gap between the restraint plates 110 of the two restraint components 10 in the same group defines a battery placement cavity 410, and the battery 300 placement slot is used to place the battery 300.

[0099] In these embodiments, the battery 300 restraint clamp not only includes the aforementioned restraint assembly 10, but also adds a carrier member 400. The carrier member 400 is used to fix and support multiple sets of restraint assemblies 10. The carrier member 400 has a second preset direction, which is parallel to the first preset direction. At least multiple sets of restraint assemblies 10 are provided on the carrier member 400, and these restraint assemblies 10 are arranged sequentially in the second preset direction.

[0100] Each set of restraint components 10 consists of two units, and each set of restraint components 10 is arranged opposite to each other. A battery placement cavity 410 is formed by the gap between the restraint plates 110 of the two restraint components 10 in the same set, for placing the battery 300. The battery placement cavity 410 is formed by the gap between the restraint plates 110 of the two restraint components 10 in the same set. The size of the battery placement cavity 410 should match the size of the battery 300 to ensure that the battery 300 does not shift during placement and fixation.

[0101] The battery 300 is placed in the battery placement cavity 410, ensuring that both sides of the battery 300 are in contact with the front faces 113 of the two restraint plates 110. Fluid is injected into the bladder 210 through the fluid control system, causing the bladder 210 to expand and push the restraint plates 110 towards the side of the battery 300 casing. The front faces 113 of the restraint plates 110 fit tightly against the battery 300 casing, applying uniform pressure to the side of the battery 300 and preventing unevenness on the surface of the battery 300 during positive and negative pressure breathing. When it is necessary to remove the battery 300, the fluid in the bladder 210 is expelled through the fluid control system, causing the bladder 210 to contract and the restraint plates 110 to move away from the battery 300 casing. A certain distance is maintained between the restraint plates 110 and the battery 300 casing, releasing the restraint on the battery 300, allowing for easy removal of the battery 300.

[0102] Clearly, the design of multiple restraint components 10 allows the battery 300 restraint fixture to process multiple batteries 300 simultaneously, improving production efficiency. Each restraint component 10 operates independently without affecting others, ensuring that each battery 300 receives uniform restraint and protection. The opposing arrangement of each restraint component 10 ensures that both sides of the battery 300 are subjected to uniform pressure simultaneously, preventing asymmetrical deformation of the battery 300 during positive and negative pressure breathing. The opposing arrangement also provides better stability, preventing the battery 300 from tilting or shifting during processing.

[0103] For example, the support member 400 can be designed as a frame structure using high-strength materials such as stainless steel or aluminum alloy to ensure structural stability and durability. Optionally, guide rails or sliders can be provided on the support member 400 to ensure precise movement of the restraint assembly 10 in a second preset direction to adjust the size of the battery placement cavity 410 to accommodate batteries 300 of different sizes.

[0104] like Figure 6 As shown, in some embodiments, the carrier 400 has a receiving groove that extends along a second preset direction, the mounting base 220 has a plug-in end, the groove wall of the receiving groove has a slot, and the plug-in end passes through the slot to limit the movement of the mounting base 220 in the second preset direction.

[0105] In these embodiments, the carrier 400 has a receiving groove extending along a second preset direction. A mounting base 220 is used to fix the restraint assembly 10, and the mounting base 220 has a plug-in end. The plug-in end is designed so that the mounting base 220 can be inserted into a slot in the receiving groove, thereby enabling the mounting base 220 to be positioned and moved in the second preset direction. The slot is designed to ensure that the plug-in end can be smoothly inserted and removed, while providing sufficient friction to prevent the mounting base 220 from loosening during operation. The plug-in engagement between the plug-in end and the slot enables a detachable connection between the carrier 400 and the restraint assembly 10.

[0106] For example, the plug-in end of the mounting base 220 is inserted into the slot of the receiving groove to ensure the positioning of the mounting base 220 in a second predetermined direction. The size and shape of the slot should match the plug-in end to ensure the stability and accuracy of the mounting base 220. Of course, in other embodiments, the mounting base 220 may also be connected to the carrier 400 by screws.

[0107] For example, the mounting base 220 is configured as a plate, and the cross-section of the mounting base 220 and the receiving groove are parallel.

[0108] like Figure 5 As shown, in some embodiments, the mounting bases 220 of adjacent restraint assemblies 10 are integrated into each other.

[0109] In these embodiments, installation is simplified by integrating the mounting bases 220 that are close to each other in adjacent groups of restraint assemblies 10. In other words, sharing a single mounting base 220 reduces the number of parts and lowers costs.

[0112] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
