Description

Technical Field

[0001] The present invention belongs to the technical field of flexible batteries, and in particular relates to a flexible component battery sheet vibration breaking device and a vibration breaking method. Background Art

[0002] In order to achieve the windability of flexible components, large-sized battery cells need to be broken into hundreds of smaller battery cells. The traditional way to split large flexible component battery cells into small pieces is mainly to manually break the large pieces into long strips, and then break the long strips into small pieces one by one. The disadvantages of this production method are low efficiency and high production costs, and it is not suitable for mass production.

[0003] Existing large-size solar cells typically consist of a protective layer, adhesive, and silicon wafer stacked in sequence. With the development of existing technologies, a process has emerged that involves performing a double fracture of large-size solar cells. This process involves first fracturing the protective layer and silicon wafer, leaving the cell connected after the fracture, creating a semi-fractured state. A second fracture is then performed to break the adhesive. The main advantage of this process is that it significantly reduces fracture pressure, effectively protects the cell structure, and prevents cell misalignment and disorder.

[0004] However, the current two-step process usually uses a splitting shaft to split the cells. That is, a splitting shaft is used to press down on the cracks on the cell in sequence. This method is first used to split the protective layer and the silicon wafer, and then the adhesive is further split. The disadvantage of this production method is that the cracks need to be broken in sequence, and the splitting efficiency is not high enough.

[0005] It should be noted that this part of the present invention only provides background technology related to the present invention and does not necessarily constitute prior art or public known technology. Summary of the Invention

[0010] Preferably, each first guide column is provided with a first limiting member that can move up and down to limit the vibration frame.

[0011] Preferably, a plurality of second guide post fixing plates are provided on the top surface of the vibration mounting base plate, and a plurality of second guide posts are provided on each second guide post fixing plate. The plurality of second guide posts pass through the vibration mounting base plate and extend downward into the plurality of second guide sleeves on the pressing plate.

[0012] Preferably, a plurality of third guide pillars are provided on the top surface of the vibration plate, and the plurality of third guide pillars extend upward into a plurality of third guide sleeves on the vibration mounting base plate.

[0017] In a second aspect, the present invention provides a method for vibrating and breaking a flexible module battery sheet. The method is applied to the above-mentioned flexible module battery sheet vibration breaking device. The method comprises:

[0018] S102, multiple vibrating parts and multiple follower plates clamp the small battery cells in odd or even rows of battery cells in the upper and lower parts;

[0019] S104: The first driving member and the first elastic member drive the plurality of vibrating parts to vibrate up and down;

[0020] S106 , the plurality of follower plates follow the plurality of vibrating parts to move synchronously via the plurality of second elastic members, thereby driving the odd-numbered or even-numbered rows of small battery cells to vibrate up and down, so as to synchronously break the adhesive between the plurality of rows of small battery cells.

[0021] Preferably, S104 specifically includes the intermittent extension of the moving end of the first driving member to drive the multiple vibration parts to move downward through the bottom surface of the vibration frame.

[0022] The beneficial effects of the present invention are:

[0023] 1. This invention utilizes high-frequency vibrations to simultaneously sever all adhesive bonds through the synergistic effect of a vibrating assembly and a platform assembly. The vibrating plate's multiple vibrating sections and a follower plate clamp the battery cells vertically. A first driver intermittently drives the vibrating section downward, combining with the rebound of a first elastic member to achieve up-and-down vibration. Simultaneously, the follower plate, via a second elastic member, synchronously follows the vibrations, generating staggered shear stresses in adjacent rows of small battery cells, severing all adhesive bonds simultaneously. Compared to traditional splitting shafts that require individual downward pressure, this significantly improves production efficiency and is particularly suitable for mass production of small battery cells under 50mm x 50mm.

[0024] 2. The vibration fracture process is flexible and controllable, and fragments are precisely repositioned. The vibrating unit and follower plate are cushioned by elastic components to prevent rigid impact damage to the silicon wafer. After vibration is complete, the elastic components rebound and automatically push the cracked small cells back to a horizontal position. Combined with the follower plate structure and the positioning of the feed plate, the fragments are prevented from tilting or stacking, significantly minimizing misalignment and allowing them to be directly transferred to the next process.

[0025] 3. High mechanical synchronization and stable cracking accuracy. The vibration plate achieves vertical directional vibration through the guide pillar and guide sleeve matching structure, eliminating lateral deviation. The vibration part and the follower plate adopt an active follower matching paired design, and the battery cell is adsorbed by the vacuum suction port to ensure that the battery cell does not move during the vibration process, effectively improving the uniformity of the adhesive cracking.

[0026] 4. The device is compatible with automated production lines, significantly reducing costs and increasing efficiency. Through the coordination of the lifting component, vibration component, and platform component, the entire process of pressing, vibrating, and resetting is automated. This significantly shortens the time required for a single fracture, reduces manual intervention, and effectively reduces the defective fragment rate, making it suitable for the continuous production of flexible battery components.

[0040] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" are generally understood in conjunction with the directions shown in the drawings and actual applications.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0042] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0043] The endpoints of the ranges and any values ​​disclosed herein are not limited to the precise ranges or values, and such ranges or values ​​should be understood to encompass values ​​approximate to such ranges or values. For numerical ranges, the values ​​between the endpoints of each range, between the endpoints of each range and individual point values, and between individual point values ​​can be combined to form one or more new numerical ranges, and such numerical ranges should be considered specifically disclosed herein. The terms "optional" and "optional" both mean that a range may or may not be included (or may or may not be present).

[0044] The battery cells are arranged in a rectangular shape. After production, the cell size is small (500mm*500mm). They need to be broken into multiple small pieces (50mm*50mm). That is, one cell needs to be broken into approximately 100 small pieces (arranged in a rectangular shape). Manual breaking of such a small size and quantity is obviously not suitable. The force application point is difficult to grasp, making it difficult to break. It is also time-consuming and labor-intensive, with low breaking efficiency and low automation, making it unsuitable for mass production. The disadvantages of using a splitting shaft to press down on the cracks on the cell in sequence are that debugging is cumbersome and requires a high level of technical skills from the equipment debugger. The cracks need to be broken in sequence, and the breaking efficiency is not high enough. Therefore, the vibration breaking method of the present invention is used to break the cell cells. But it is not limited to this. In other embodiments, the size of the battery cell may be 600mm*600mm, 700mm*700mm, 800mm*800mm, and the size of the small piece may be 30mm*30mm, 40mm*40mm. There is no specific limitation on the size of the battery cell and the size of the small piece.

[0045] The present invention provides a flexible component battery cell vibration breaking device 10, wherein the battery cell has been split into a plurality of small battery cells connected to each other by adhesive, such as Figures 1 to 6 As shown, the vibration breaking device 10 includes a vibration assembly 100 and a platform assembly 200; the vibration assembly 100 includes a vibration frame 110, a vibration plate 120, a first driving member 130, and a plurality of first elastic members 140; the vibration plate 120 is arranged in the vibration frame 110, and the bottom surface of the vibration plate 120 has a plurality of vibration parts 121 evenly spaced, the first driving member 130 is arranged on the vibration frame 110 and is used to intermittently drive the plurality of vibration parts 121 to move downward through the bottom surface of the vibration frame 110, and the bottom surface of the vibration plate 120 also has a plurality of first elastic members 140, and the plurality of first elastic members 140 cause the plurality of vibration parts 121 to move upward when they rebound; the platform assembly 200 includes a platform bottom plate 21 0, multiple follower plates 220, multiple second elastic members 230; multiple follower plates 220 are evenly spaced on the platform bottom plate 210, and a second elastic member 230 is provided between the bottom of each follower plate 220 and the platform bottom plate 210, and multiple vibration parts 121 are opposite to the multiple follower plates 220 one by one in the upper and lower directions; wherein, the multiple vibration parts 121 and the multiple follower plates 220 clamp the odd-numbered rows or even-numbered rows of small battery cells in the upper and lower directions, the first driving member 130 and the first elastic member 140 drive the multiple vibration parts 121 to vibrate up and down, and the multiple follower plates 220 follow the multiple vibration parts 121 to move synchronously through the multiple second elastic members 230 to synchronously break the adhesive between the multiple rows of small battery cells.

[0046] The present invention utilizes high-frequency vibrations through the synergistic effect of the vibration assembly 100 and the platform assembly 200 to generate staggered shear stress in adjacent rows of small cells, breaking all adhesive bonds simultaneously. Compared to traditional splitting shafts that require individual downward pressure, this significantly improves production efficiency and is suitable for mass production of small cells.

[0047] It is understandable that the odd and even rows are specifically counted starting from the outermost row on one side of the small battery cell and then row by row. Specifically, for example, the battery cell is composed of four rows of small battery cells, and each row of small battery cells is connected by adhesive. Then, when the battery cell is split, when the multiple vibration parts 121 and the multiple follower plates 220 clamp the small battery cells in the first and third rows of the battery cell, the small battery cells in the second and fourth rows of the battery cell do not vibrate. When the multiple vibration parts 121 and the multiple follower plates 220 clamp the small battery cells in the second and fourth rows of the battery cell, the small battery cells in the first and third rows of the battery cell do not vibrate.

[0048] It should be noted that the best use scenario of the flexible component battery cell vibration breaking device 10 of the present invention is: after the battery cell has been split into multiple small battery cells connected to each other by adhesive, the adhesive between the multiple rows of small battery cells is broken. Because the vibration breaking device 10 of the present invention provides shear force along the vibration direction for every other row of small battery cells, this shear force is particularly suitable for breaking adhesives and has a high breaking efficiency. For brittle hard materials such as silicon wafers and protective layers, the shear force has a lower breaking efficiency. Nevertheless, it should be noted that the above scenario is only a preferred use scenario of the present invention and does not constitute the sole limitation of the present invention. Even if the present invention is used to directly break the protective layer, adhesive, and silicon wafer of the battery cell at the same time, or even if the present invention is used to break only the protective layer and silicon wafer of the battery cell, it should still fall within the protection scope of the present invention.

[0049] Preferably, if Figure 2 and Figure 3 As shown, the vibration frame 110 includes a vibration mounting base plate 111 and a pressing plate 112; the vibration mounting base plate 111 and the pressing plate 112 are arranged relative to each other up and down, and the vibration plate 120 is arranged between the vibration mounting base plate 111 and the pressing plate 112. The first driving member 130 is arranged on the top surface of the vibration mounting base plate 111, and its moving end passes through the vibration mounting base plate 111 and abuts against the top surface of the vibration plate 120. A plurality of first elastic members 140 are arranged between the bottom surface of the vibration plate 120 and the pressing plate 112, and the plurality of vibration parts 121 can move up and down through the pressing plate 112.

[0050] As you can understand, the vibration frame 110 utilizes a dual-layer structure consisting of a vibration mounting base 111 and a pressure plate 112. The vibration plate 120 is precisely constrained between the two, forming a stable vibration transmission path. The moving end of the first driving member 130 directly acts on the top surface of the vibration plate 120 through the vibration mounting base 111, driving it downward. The first elastic member 140 on the bottom surface of the vibration plate 120 provides a reverse rebound force. Together, these two elements achieve high-frequency reciprocating motion of the vibrating portion 121.

[0051] Preferably, if Figure 4 As shown, the vibration plate 120 includes a laterally extending substrate and a plurality of vibration parts 121. The plurality of vibration parts 121 are a parallel array composed of longitudinal rectangular racks arranged equidistantly on the substrate. The ends of the racks are flat surfaces, so that each row of racks can evenly press against the entire row of small battery cells at the same time.

[0052] Preferably, if Figure 3 As shown, the pressing plate 112 is also provided with a through hole that precisely matches the rack array of the vibration part 121. A small gap is maintained between the through hole and the rack, which ensures that the vibration part 121 can freely pass through the pressing plate 112 to contact the battery cell and effectively limits lateral deviation.

[0053] It can be understood that the vibration part 121 is guided by the through hole of the pressing plate 112, so that the vibration energy is directed to a specific row of battery cells to avoid vibration dispersion; at the same time, the straight end of the rack contacts the full width of the battery cell to ensure that the shear force is evenly applied to the entire adhesive. Combined with the synchronous elastic follow-up of the follower plate 220, the small battery cells in odd or even rows produce vertical vibrations, forming concentrated alternating shear stress at the adhesive to achieve efficient synchronous fracture, and the rack array design can cover all target rows of the entire battery at one time, greatly shortening the fracture cycle.

[0054] Preferably, the first driving member 130 is a high-frequency vibration cylinder, the moving end of which is a rigid push rod, which intermittently extends and abuts against the top surface of the vibration plate 120 to drive the multiple vibration parts 121 to move downward.

[0055] Preferably, if Figure 2 and Figure 3 As shown, the first elastic member 140 is a spring, which is evenly distributed between the bottom surface of the vibration plate 120 and the pressing plate 112, and provides a reverse rebound force to drive the vibration part 121 to return to its original position and rise when the rigid push rod retracts.

[0056] It is understandable that the present invention realizes high-frequency directional reciprocating motion of the vibrating part 121 through the synergistic effect of the pulsed power output of the cylinder and the elastic energy storage characteristics of the spring.

[0057] Preferably, if Figure 2 As shown, the first driving member 130 is disposed on the top surface of the vibration mounting base 111 through a first driving member mounting block 131 .

[0058] Preferably, if Figure 3 As shown, a through hole is provided on the vibration installation base plate 111 to accommodate the movement end of the first driving member 130 to pass through.

[0059] Preferably, if Figure 2 and Figure 5 As shown, a plurality of first guide sleeves 150 are circumferentially arranged between the vibration mounting base plate 111 and the pressing plate 112 , a plurality of first guide pillars 211 are provided on the platform base plate 210 , and the plurality of first guide sleeves 150 are correspondingly sleeved on the plurality of first guide pillars 211 to guide the vibration frame 110 .

[0060] It is understood that the multiple first guide sleeves 150 circumferentially arranged between the vibration mounting base 111 and the pressure plate 112 cooperate with the corresponding multiple first guide posts 211 on the platform base 210 to form a high-precision guide structure, ensuring that the vertical motion trajectory of the vibration frame 110 is strictly limited. This design eliminates lateral offset or swing during vibration through the rigid fit of the guide posts and sleeves, directing the vibration energy to the adhesive area of ​​a specific row of battery cells, avoiding uneven cracking or silicon wafer damage caused by vibration dispersion. At the same time, the sliding fit of the guide posts and sleeves provides stable mechanical support for high-frequency vibration, significantly improving the coordination accuracy of the vibration assembly 100 and the platform assembly 200.

[0061] Preferably, if Figure 5 As shown, each first guide column 211 is provided with a first position-limiting member 212 that can move up and down to limit the vibration frame 110. More preferably, the first position-limiting member 212 is preferably an adjustable stop bolt.

[0062] It is understood that in the vibration-fracture device 10, by providing a vertically movable stop bolt as the first limiter 212 on the first guide post 211, the downward stroke of the vibration frame 110 can be precisely adjusted and rigidly limited. This design allows for flexible adjustment of the downward stroke of the vibration frame 110 according to the thickness of the battery cells, ensuring that the clamping force of the vibrating portion 121 and the follower plate 220 on the battery cells is always within the optimal range, thus avoiding silicon wafer fracture caused by excessive downward pressure or incomplete fracture caused by insufficient downward pressure.

[0063] Preferably, if Figure 2 and Figure 3 As shown, a plurality of second guide column fixing plates 160 are provided on the top surface of the vibration mounting base plate 111, and a plurality of second guide columns 161 are provided on each second guide column fixing plate 160. The plurality of second guide columns 161 pass through the vibration mounting base plate 111 and extend downward to the plurality of second guide sleeves 162 on the pressing plate 112.

[0064] It can be understood that the present invention achieves precise positioning of the core moving parts of the vibration assembly 100 through a through-type guide structure. The sliding fit of the second guide post 161 and the second guide sleeve 162 provides a high-rigidity vertical guide constraint between the vibration mounting base 111 and the pressure plate 112, effectively eliminating the lateral offset and swing of the vibration mounting base 111 and the pressure plate 112, and ensuring that the vibration energy is accurately and directional transmitted to the adhesive area of ​​a specific row of battery cells; at the same time, the distributed layout of multiple guide posts significantly enhances the overall torsional rigidity of the vibration frame 110, avoids deformation of the mechanism, and thus ensures the alignment accuracy of the vibration part 121 and the tooth groove of the follower plate 220. In addition, the full-stroke through-design of the guide post enables the vibration plate 120 to maintain an effective guide length at the extreme position, further enhancing the position controllability and mechanism durability of the vibration process.

[0065] Preferably, if Figure 2 and Figure 3 As shown, a plurality of third guide pillars 170 are provided on the top surface of the vibration plate 120 , and the plurality of third guide pillars 170 extend upward into a plurality of third guide sleeves 171 on the vibration installation base plate 111 .

[0066] It can be understood that the present invention precisely constrains the motion trajectory of the vibration plate 120 through a rigid guide structure, ensuring that high-frequency vibration energy is directed along the vertical direction to the adhesive area of ​​a specific row of battery cells, while eliminating the risk of lateral offset and vibration dispersion. Specifically, the precise sliding fit of the third guide post 170 and the third guide sleeve 171 forms a high-rigidity vertical guide channel, which allows the vibration plate 120 to strictly maintain vertical lifting and lowering during high-speed reciprocating motion to avoid deflection; this not only significantly improves the alignment accuracy of the vibration part 121 and the follower plate 220 tooth groove, ensuring that each adhesive is evenly loaded, but also greatly reduces vibration energy loss, allowing the alternating shear stress to be efficiently concentrated at the target crack. In addition, by limiting the degrees of freedom of the vibration plate 120, the design enhances the overall stability of the mechanism, reduces mechanical wear caused by vibration impact, extends the service life of the equipment, and provides reliable protection for the consistency of the cracks in the high-frequency vibration mode.

[0067] Preferably, if Figure 2 and Figure 3 As shown, a plurality of second stoppers 180 are further provided on the top surface of the vibration mounting base 111. The lower portions of the plurality of second stoppers 180 pass through the vibration mounting base 111 and extend downwardly to be fixedly connected to the press plate 112. A third elastic member 181 is sleeved on the lower portion of the second stoppers 180. The top and bottom portions of the third elastic member 181 abut against the vibration mounting base 111 and the press plate 112, respectively. More preferably, the second stoppers 180 are driving screws and the third elastic member 181 is a spring.

[0068] It can be understood that the present invention deeply integrates rigid limiting and elastic buffering, which not only ensures the efficiency and reliability of the splitting process, but also significantly improves the product yield and equipment automation compatibility through adaptive pressure control. Specifically, during the downward pressing process of the vibration component 100, when the pressing plate 112 contacts the battery cell, the third elastic member 181 absorbs mechanical impact through elastic deformation, provides a flexible buffer space, and effectively avoids the risk of battery cell fragmentation caused by rigid stroke; in the rising stage after the splitting is completed, when the lifting component 300 drives the vibration component 100 to move upward as a whole, the rebound force of the third elastic member 181 continues to act on the pressing plate 112, so that it always maintains stable pressure on the battery cell during the process of detaching from the battery cell, completely eliminating the risk of displacement of fragments due to vacuum release or mechanical separation, and ensuring that the cracked small battery cells maintain precise alignment.

[0069] Preferably, if Figure 5 and Figure 6 As shown, the top surface of the follower plate 220 is provided with a plurality of vacuum suction ports, the bottom surface of the follower plate 220 is connected to the vacuum connecting plate 221 , and the bottom surface of the vacuum connecting plate 221 is connected to the platform bottom plate 210 through the second elastic member 230 .

[0070] More preferably, a vacuum interface is provided on the vacuum connection plate 221 to connect an external vacuum pumping component, and the second elastic member 230 is a spring.

[0071] It can be understood that the present invention realizes precise adsorption and fixation of the battery cell during the vibration fracture process through the synergistic effect of the multiple vacuum suction ports provided on the top surface of the follower plate 220 and the vacuum connecting plate 221 on the bottom surface, thereby effectively preventing the displacement or disorder of fragments caused by high-frequency vibration; at the same time, the vacuum connecting plate 221 is elastically connected to the platform bottom plate 210 through the second elastic member 230, so that the follower plate 220 can actively follow the up and down movement of the vibration part 121 and displace synchronously, which not only provides the necessary flexible shear space for the adhesive to fracture, avoids rigid impact damage to the silicon wafer, but also ensures that the small battery cell automatically returns to a horizontal state after cracking through elastic reset; in addition, the vacuum interface reserved on the vacuum connecting plate 221 can be directly connected to an external vacuum pumping system, which simplifies the gas circuit integration and ensures balanced and stable adsorption force, and is particularly suitable for high-frequency continuous operation scenarios of automated production lines, significantly improving the uniformity of the cracks and production reliability.

[0072] Preferably, the vibration fracture device 10 also includes a vacuum pump component (not shown in the figure), which includes a vacuum pump and multiple branch pipes. The vacuum pump is connected to multiple branch pipes at the same time, and each branch pipe is connected to a vacuum interface to realize the vacuum adsorption function of each vacuum suction port and ensure the vacuum adsorption effect.

[0073] Preferably, the vacuum pump assembly also includes a main pipeline, a vacuum gas distribution block, multiple branch pipelines and a bus. The vacuum pump is connected to the vacuum gas distribution block through the main pipeline, the vacuum gas distribution block is connected to the bus through multiple branch pipelines, the bus is connected to multiple vacuum interfaces through multiple branch pipelines, the vacuum gas distribution block is used to realize the first-level gas distribution function, and the bus is used to realize the second-level gas distribution function. Specifically, through the two-level gas distribution of the vacuum gas distribution block and the bus, the thicker main pipeline is divided into multiple thinner branch pipelines step by step, and connected to multiple vacuum interfaces, avoiding the situation where the vacuum pump directly leads to multiple vacuum pipelines to connect to multiple vacuum interfaces, thereby avoiding the problem of uneven airflow in multiple vacuum pipelines due to large changes in pipeline diameter, and thus realizing the step-by-step transition function, ensuring that the pressure of multiple pipelines (multiple branch pipelines or multiple branch pipelines) at the same level is balanced, making the entire vacuum pumping system stable and reliable.

[0074] Preferably, if Figure 5As shown, the platform assembly 200 also includes a middle partition plate 240 and a placing plate 250 which are sequentially arranged on the platform bottom plate 210, and the middle partition plate 240 includes a plurality of first limiting portions 241, and the plurality of first limiting portions 241 are filled one-to-one between the gaps at the lower portions of the plurality of follower plates 220; the placing plate 250 includes a plurality of second limiting portions 251, and the plurality of second limiting portions 251 are filled one-to-one between the gaps at the upper portions of the plurality of follower plates 220, and each second limiting portion 251 is arranged on the first limiting portion 241; wherein, the width of the lower portion of the follower plate 220 is greater than the width of the upper portion, and the width of the first limiting portion 241 is less than the width of the second limiting portion 251.

[0075] As can be understood, the present invention achieves multiple mechanical constraints and precise resetting functions through the stepped structure of the follower plate 220 (i.e., the lower width is greater than the upper width), combined with the nested stopper system formed by the first stopper 241 of the middle partition plate 240 and the second stopper 251 of the holding plate 250. Specifically, the first stopper 241 fills the gap below the follower plate 220, limiting its horizontal displacement. The second stopper 251 fills the gap above the follower plate 220 and overlaps the first stopper 241, forming a stepped stopper surface. This ensures that the follower plate 220 can only move vertically during vibration, completely eliminating the risk of lateral movement. At the same time, the "convex" profile of the follower plate 220, which is narrow at the top and wide at the bottom, and the size difference of the stepped limit portion (the width of the first limit portion 241 is smaller than that of the second limit portion 251) constitute a self-locking reset structure: when the vibration component 100 rises, the follower plate 220 is pushed upward by the second elastic member 230, and its wide lower part is precisely blocked by the wide limit surface of the second limit portion 251, forcing all follower plates 220 to stop at the same horizontal height, ensuring that the small battery cell fragments after cracking are restored to the same plane under the action of the rebound force of the second elastic member 230, effectively avoiding the tilting, stacking or overall disorder of the fragments due to vibration dislocation, and significantly improving the product neatness and subsequent chip retrieval efficiency.

[0076] Preferably, when the multiple vibrating parts 121 and the multiple follower plates 220 clamp the odd-numbered or even-numbered rows of small battery cells, the multiple rows of small battery cells that are not clamped are clamped and fixed by the pressing plate 112 and the placing plate 250. This design uses the pressing plate 112 and the placing plate 250 to coordinately fix the even-numbered or odd-numbered rows of small battery cells that are not clamped by the vibrating parts 121 and the follower plates 220, effectively isolating the transmission of vibration shear stress and preventing the misalignment, tilting, or stacking of adjacent rows of battery cells due to the involved movement.

[0077] Preferably, if Figure 7As shown, the vibration breaking device 10 also includes a lifting assembly 300, which includes a support frame 310 and a second driving member 320; the second driving member 320 is arranged on the support frame 310, and the moving end of the second driving member 320 is fixedly connected to the vibration frame 110 through the lifting frame 330 to drive the vibration frame 110 to move up and down.

[0078] It can be understood that the present invention drives the vibration frame 110 to be precisely pressed down and reset through the coordinated action of the support frame 310 and the second driving member 320. Specifically, the second driving member 320 is connected to the vibration frame 110 through the lifting frame 330 to realize the overall vertical lifting of the vibration assembly 100, ensuring that the pressure of the pressing plate 112 is uniform and controllable when it contacts the battery cell, avoiding force deviation caused by manual placement; the lifting process is combined with the precise guiding structure of the guide column and guide sleeve to eliminate the risk of lateral offset, so that the vibration part 121 and the follower plate 220 are strictly aligned, ensuring the direction of high-frequency vibration energy to the adhesive area; at the same time, the timing linkage of the lifting assembly 300 and the vibration assembly 100 realizes the full process automation of pressing-vibration-separation, greatly shortens the single fracture cycle, and significantly improves production efficiency, especially adapted to the high beat requirements of continuous production lines.

[0079] Preferably, if Figure 7 As shown, the support frame 310 includes two support columns 311 and a power mounting plate 312 disposed between the tops of the two support columns 311. The power mounting plate 312 and the two support columns 311 together form a structure similar to a door. The two support columns 311 are respectively disposed on either side of the platform assembly 200, and the power mounting plate 312 is disposed above the vibration assembly 100.

[0080] Preferably, if Figure 2 As shown, the lifting frame 330 includes two lifting support plates 331 and a lifting connection plate 332 arranged between the tops of the two lifting support plates 331. The two lifting support plates 331 are arranged on the vibration installation base plate 111, and the first driving member 130 is arranged in the lifting frame 330.

[0081] Preferably, the second driving member 320 is a power source such as a motor, a stepper motor, a servo motor, a cylinder, etc. More preferably, the second driving member 320 is a cylinder.

[0082] Preferably, if Figure 7As shown, the second driving member 320 may include a power joint fixing plate 321, a power joint 322, and a power cylinder 323. The power cylinder 323 is mounted on the power mounting plate 312. One end of the power joint 322 is connected to the power cylinder 323, and the other end passes through the power mounting plate 312 and is connected to the power joint fixing plate 321. The power joint fixing plate 321 is fixedly connected to the lifting connecting plate 332. The power cylinder 323 drives the power joint 322 to move up and down, thereby driving the vibration assembly 100 to move through the lifting frame 330.

[0083] Preferably, the surface of the pressing plate 112 can be covered with a polyurethane or rubber coating to prevent impact and damage to the cell. This design effectively prevents microcracks or hidden cracks caused by direct contact between the rigid pressing plate 112 and the brittle silicon wafer. Furthermore, the high coefficient of friction between the soft coating and the cell surface enhances holding stability, preventing lateral slippage and dislocation of fragments during vibration. Its elastic deformation provides the necessary flexible shear space for adhesive fracture, ensuring that vibration energy is precisely focused on the target crack area. This improves cracking efficiency while ensuring product yield, further enhancing the device's compatibility with automated continuous production.

[0084] The present invention provides a method for vibrating and breaking a flexible module battery sheet. The method is applied to the flexible module battery sheet vibration breaking device 10. The method includes:

[0085] S100, placing a battery cell having a plurality of small battery cells connected to each other by adhesive on a loading plate 250, and fixing the small battery cells in odd or even rows of the battery cell by vacuum adsorption through a plurality of follower plates 220;

[0086] S101, the lifting assembly 300 drives the vibration frame 110 to descend, the pressing plate 112 and the placing plate 250 clamp the battery cell, and the third elastic member 181 is compressed;

[0087] S102, multiple vibration parts 121 and multiple follower plates 220 clamp the small battery cells in odd or even rows of battery cells from top to bottom;

[0088] S102 further includes the pressing plate 112 and the placing plate 250 fixing the even-numbered rows or odd-numbered rows of small battery cells that are not clamped by the vibrating portion 121 and the following plate 220 .

[0089] S104: The first driving member 130 and the first elastic member 140 drive the plurality of vibration parts 121 to vibrate up and down;

[0090] S104 specifically includes the intermittent extension of the moving end of the first driving member 130 to drive the multiple vibration parts 121 to move downward through the bottom surface of the vibration frame 110; when the moving end of the first driving member 130 is extended, the bottom surface of the vibration plate 120 compresses the first elastic member 140, and the multiple vibration parts 121 move downward through the bottom surface of the vibration frame 110; when the moving end of the first driving member 130 is retracted, the first elastic member 140 rebounds to drive the multiple vibration parts 121 to move upward, and the moving end of the first driving member 130 continuously expands and contracts, and then the multiple vibration parts 121 are driven to vibrate up and down through the first driving member 130 and the first elastic member 140.

[0091] S106, the plurality of follower plates 220 follow the plurality of vibrating parts 121 to move synchronously via the plurality of second elastic members 230, thereby driving the odd-numbered or even-numbered rows of small battery cells to vibrate up and down, thereby synchronously breaking the adhesive between the plurality of rows of small battery cells;

[0092] S108, the lifting assembly 300 drives the vibration frame 110 to rise, the third elastic member 181 rebounds, so that the pressing plate 112 always maintains stable pressure on the battery cell during the process of separating from the battery cell, and the second elastic member 230 rebounds, so that all the follower plates 220 stop at the same horizontal height.

[0093] The flexible component cell vibration fracturing method provided by the present invention utilizes high-frequency vibration to simultaneously sever all adhesives through the synergistic effect of the vibration component 100 and the platform component 200, significantly improving the fracturing efficiency and product quality. The elastic buffer design of the vibrating portion 121 and the follower plate 220 prevents rigid impact damage to the silicon wafers. The press plate 112 and the placement plate 250 coordinately fix and isolate the non-vibrating row of cell cells, preventing fragment dislocation. After fracturing, the third elastic member 181 rebounds, allowing the press plate 112 to continue pressing the cell cells during the separation process. Combined with the stepped limiting structure of the follower plate 220 and the rebound of the second elastic member 230, all small cell cells are forced to return to the same horizontal plane, eliminating the risk of tilted stacking. In addition, the rack array of the vibration part 121 and the vacuum adsorption of the follower plate 220 ensure that the shear force evenly covers the entire adhesive strip. The rigid guiding structure of the guide pin and guide sleeve prevents lateral deviation, so that the fracture uniformity meets the requirements of the automated production line, greatly shortens the single operation cycle, reduces the intensity of manual intervention and the defective rate of fragments, and is especially suitable for the large-scale continuous production of small-sized battery cells below 50mm×50mm.

Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner. These simple variations and combinations should also be regarded as disclosed in the present invention and fall within the scope of protection of the present invention.
