Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a multi-station blade battery cutting and core extraction device. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage industries, blade batteries have been widely used in the field of power batteries due to their high volumetric energy density, high structural strength and good safety performance. Blade batteries are flat and long, with the outer shell mostly made of aluminum alloy. They are encapsulated with rolled or stacked cells. Scenarios such as dismantling defective products in the production process, extracting cells in the recycling process, and sampling and testing cells in the research and development stage all have an urgent need for cutting and core extraction devices.

[0003] Traditional core cutting and coring devices generally adopt a single-station architecture, with core processes such as cutting, coring, and loading / unloading arranged in sequence. Due to the limited process connection mode, the equipment needs to be stopped and waiting when performing loading / unloading operations, which cannot achieve continuous operation throughout the entire process. Ultimately, this results in low overall processing efficiency, making it difficult to match the capacity requirements of large-scale mass production. Summary of the Invention

One end of the thin external gear cylinder seat is fixedly connected to a thrust block. A connecting seat is fixedly installed on the lower surface of the thrust block, and a core-taking frame is fixedly installed on the lower surface of the connecting seat.

[0014] Preferably, the lower surface of the core-taking frame is connected to a core-taking pusher seat, and the inner side wall of the core-taking pusher seat is connected to a pusher assembly. The pusher assembly includes a cylinder mounting seat connected to the inner side of the core-taking pusher seat.

One end of the two-rod cylinder is connected to a pusher plate. There are several pusher plates, which are evenly distributed on the core-taking frame in a horizontal array.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The battery's movement trajectory is constrained by guide strips. Lateral positioning relies on a precision-ground positioning push plate and a cutting positioning block to form a rigid fit. The clamping process uses an arc-shaped flexible rubber plate to adaptively fit the battery's shape, preventing the battery from shifting, rotating, or deforming during the cutting process. Longitudinal cutting is driven by a high-precision linear slide rail through a hydraulic cylinder. Lateral cutting is combined with a limit wheel group for guidance and laser positioning calibration to ensure that the cut is flat and burr-free and the cutting trajectory is accurate. This not only avoids deformation of the outer shell but also effectively protects the internal cell separator and electrode sheets, preventing cell damage caused by cutting deviations and ensuring the reliability of subsequent cell testing or recycling.

[0016] 2. Parallel linkage between units is achieved through linear slide modules. During longitudinal cutting, the material transfer mechanism is ready simultaneously. After cutting, the material transfer action is executed immediately without any downtime. The material transfer, clamping, cutting, and flipping actions of the transverse cutting unit are continuously connected. The core extraction unit and the transverse cutting unit adjust their postures seamlessly. The entire process requires no manual intervention. From battery loading, positioning, cutting to cell extraction and material diversion, a closed-loop operation is formed. At the same time, the timing of each execution component is precise and controllable, effectively shortening the cycle of a single process and meeting the capacity requirements of large-scale mass production and recycling dismantling, significantly reducing labor costs and operational risks.

[0017] 3. By making small adjustments, the push plate and the battery cell are precisely aligned. The two-stage extension speed combined with uniform thrust control can smoothly push out the battery cell, avoiding damage caused by excessive local force. During the cutting process, negative pressure dust collection is activated simultaneously to collect metal dust and aluminum shavings in real time. This not only prevents dust from affecting the operation of the equipment and subsequent processes, but also prevents dust from harming the health of the operators. At the same time, through flexible clamping and stable transmission design, safety hazards such as short circuits and fires caused by residual battery power are avoided, improving the overall safety of the operation.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0022] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a multi-station blade battery cutting and core extraction device includes a cylinder connecting seat with a slide rail assembly on one side surface. The cylinder connecting seat is slidably connected to a cross-cutting lifting plate 36 via the slide rail assembly on one side. A pressure beam 37 is connected to one side of the cross-cutting lifting plate 36. The cutting unit 2 includes a material transfer fixing frame 21 fixedly installed on one side of the upper surface of the integral processing frame 1. The upper surface of the material transfer fixing frame 21 is fixed with a material transfer support column by bolts. A three-bar cylinder is fixedly installed on the lower surface of the material transfer fixing frame 21. A pusher plate 22 is connected to one end of the material transfer fixing frame 21 via the three-bar cylinder. The cutting unit 2 also includes a three-bar cylinder mounting seat connected to the lower surface of the linear slide module 6 via the three-bar cylinder. A fixed clamping plate 23 is connected to the front end of the three-bar cylinder mounting seat. A movable clamping plate 24 is fixedly installed on the lower surface of the three-bar cylinder mounting seat. The movable clamping plate 24 is adapted to the fixed clamping plate 23. A clamping rubber strip 25 is connected to the side of the movable clamping plate 24 near the fixed clamping plate 23.

[0023] In the embodiments of the above technical solution, the flat, elongated blade battery to be processed is smoothly transferred to the initial loading station of the overall processing frame 1 via an external conveyor line. This station is precisely connected to the working area of ​​the cutting unit 2 through a positioning pin, ensuring that the initial placement deviation of the battery is controlled within a very small range.

[0024] After receiving the PLC start signal, the three-bar cylinder integrated at the bottom of the material transfer fixing frame 21 of the cutting unit 2 extends the piston rod at a constant speed, driving the pusher plate 22 to move horizontally along the preset linear guide rail of the material transfer fixing frame 21 through the floating joint. The flexible rubber pad attached to the front end of the pusher plate 22 is tightly attached to the center position of the battery end face, applying a uniform pushing force to smoothly push the battery to the preset cutting area on the top plate 26 of the cutter table. During the pushing process, the guide strips on both sides of the top plate 26 of the cutter table provide longitudinal limit for the battery, ensuring that the longitudinal reference of the battery is aligned with the cutting blade 2. 12. After the center line of the cutting blade 213 coincides and the battery is fully entered into the cutting area, the anti-rotation thin cylinder 28 embedded in the side of the blade top plate 26 is activated. The piston rod pushes the positioning push plate 29 to move horizontally to one side of the battery. The limiting surface at the front end of the positioning push plate 29 is parallel to the reference surface of the cutting positioning block 210 until the two are respectively attached to the left and right end faces of the battery. Appropriate clamping force is applied to form a bidirectional rigid limit, which prevents the battery from horizontally shifting and rotating during the subsequent cutting process, and ensures that the cutting cut is parallel to the battery axis.

[0025] Synchronous with the lateral limiting action, the three-bar cylinder fixed to the bracket above the blade plate 26 drives the cutting and clamping rubber plate 27 to move vertically downward. The movement speed is adjustable in two stages to avoid rapid downward pressure impacting the battery casing. The cutting and clamping rubber plate 27 is made of flexible silicone material, and the bottom is machined into an arc-shaped groove that fits the shape of the blade battery. When it contacts the upper surface of the battery, it can adaptively conform to the contour of the casing. Without scratching the aluminum alloy casing, it applies uniform clamping force to firmly fix the battery on the smooth working surface of the blade plate 26, achieving complete battery positioning.

[0026] The preferred technical solution in this embodiment is: Reference Figure 6 A three-bar cylinder is fixedly installed on the lower surface of the material transfer fixing frame 21, and a pusher plate 22 is connected to one end of the three-bar cylinder of the material transfer fixing frame 21; The cutting unit 2 also includes a three-bar cylinder mounting base connected to the lower surface of the linear slide module 6 via a three-bar cylinder. A fixed clamping plate 23 is connected to the front end of the three-bar cylinder mounting base, and a movable clamping plate 24 is fixedly installed on the lower surface of the three-bar cylinder mounting base. The movable clamping plate 24 is adapted to the fixed clamping plate 23, and a clamping rubber strip 25 is connected to the side of the movable clamping plate 24 near the fixed clamping plate 23.

[0027] An anti-rotation thin-type cylinder 28 is fixedly installed on the bottom inner wall of the top plate 26 of the knife holder. One end of the anti-rotation thin-type cylinder 28 is connected to a positioning push plate 29. A cutting positioning block 210 is movably connected to the bottom inner wall of the top plate 26 of the knife holder. The cutting positioning block 210 is adapted to the positioning push plate 29 on one side. An upper knife holder 211 is fixedly installed on one end of the cylinder. An upper cutting knife 212 is fixedly installed on the upper knife holder 211 by bolts. A linear slide rail is slidably connected to one side of the upper knife holder 211. A lower knife adjustment seat 214 is fixedly installed on the bottom inner wall of the top plate 26 of the knife holder. A lower cutting knife 213 is provided on the lower knife adjustment seat 214.

[0028] After the battery completes triple positioning, the cutting unit 2 starts the longitudinal cutting process. The rigid shear driven by the hydraulic cylinder achieves the initial cutting of the battery shell. The cut penetrates the shell but does not damage the internal cells, leaving space for subsequent transverse cutting.

[0029] The hydraulic cylinder mounted on the rear side of the top plate 26 of the cutting table serves as the main cutting power source. After receiving the cutting signal, it drives the upper cutting seat 211 to move downward at high speed along the linear slide rail configured on its side. The upper cutting blade 212, which is fixed at the bottom of the upper cutting seat 211 by the internal hex bolt, moves downward synchronously. When the upper cutting blade 212 and the lower cutting blade 213 fixed on the lower cutting adjustment seat 214 form a reasonable shearing angle, the aluminum alloy shell of the battery is rigidly sheared. During the shearing process, the hydraulic cylinder output force is stable, and a narrow through-cut is made along the length of the battery, initially separating the battery shell into two symmetrical half-shell structures, avoiding damage to the internal cell separator.

[0030] After the longitudinal cutting is completed, the hydraulic cylinder switches the oil circuit through the reversing valve, driving the upper blade holder 211 and the cutting upper blade 212 to move upward and reset until the top limit sensor is triggered and stops. At the same time, the piston rod of the three-bar cylinder corresponding to the cutting clamping rubber plate 27 retracts, driving the rubber plate to move upward and reset to a height higher than the battery thickness. The anti-thinning cylinder 28 also retracts synchronously, driving the positioning push plate 29 to detach from the battery end face and orderly release the cut battery assembly.

[0031] Reference Figure 2 and Figure 5 The upper surface of the integral processing frame 1 is respectively equipped with a cutting unit 2, a cross-cutting unit 3 and a core-taking unit 4. The upper surface of the integral processing frame 1 is fixedly equipped with a material transfer bracket 5. The lower surface of the integral material transfer bracket 5 is fixedly equipped with a linear slide module 6. The upper surface of the integral processing frame 1 has linear slide rails on both sides. The side of the upper surface of the integral processing frame 1 near the linear slide rail is connected to a rodless cylinder. The upper surface of the rodless cylinder is fixedly equipped with a cylinder connecting seat. The cross-cutting unit 3 includes an external thread thin cylinder 31 connected to the lower surface of the linear slide module 6. One side extension end of the external thread thin cylinder 31 is fixedly equipped with a thrust connecting seat 32. The lower surface of the thrust connecting seat 32 is fixedly equipped with a cross-cutting material transfer bracket 33 by bolts. A three-rod cylinder is connected to the inner side wall of the cross-cutting material transfer bracket 33. The downward extension end of the three-rod cylinder is connected to a material transfer push plate 35.

[0032] While the longitudinal cutting operation is underway, the linear slide module 6 at the bottom of the transfer bracket 5 carries the three-cylinder mounting base of the cutting unit 2 and moves to a position directly above the cutting area. A visual sensor confirms the completion of the battery cutting. After the battery assembly is released, the three-cylinder immediately actuates, and the piston rod drives the movable clamping plate 24 to move towards the fixed clamping plate 23. The clamping adhesive strip 25 attached to the inner side of the movable clamping plate 24, together with the reference surface of the fixed clamping plate 23, clamps both ends of the battery assembly. The clamping force is controlled within a reasonable range, ensuring stable clamping while avoiding damage to the outer casing. Subsequently, the linear slide module 6 drives the clamping mechanism and the battery assembly to move horizontally and precisely to the working position of the transverse cutting unit 3.

[0033] After the linear slide module 6 transfers the battery pack to the cross-cutting station, it triggers the station limit sensor, and the slide immediately stops. Then, the piston rod of the external thread thin cylinder 31 of the cross-cutting unit 3 extends, pushing the thrust connecting seat 32 and the cross-cutting transfer frame 33, which is fixed to it by bolts, to move downwards until the transfer push plate 35 on the inner side of the cross-cutting transfer frame 33 is aligned with the end face of the battery pack. Immediately afterwards, the three-bar cylinder built into the cross-cutting transfer frame 33 drives the transfer push plate 35 to move. The flexible pad at the front end of the push plate fits against the end face of the battery, and smoothly pushes the battery pack between the two sets of clamping beams 82 of the flipping component 8. The pushing stroke is precisely controlled by the displacement sensor to ensure that the transverse cutting line of the battery coincides with the rotation trajectory of the saw blade 75.

[0034] After the battery assembly is fully inserted between the clamping beams 82, the clamping strips 821, made of polyurethane and with anti-slip particles on the surface, installed on the inner side of the clamping beams 82, automatically adhere to the two sides of the battery casing and apply appropriate clamping force under the drive of the built-in micro cylinder.

[0035] Reference Figure 7 , Figure 8 and Figure 9 The cross-cutting unit 3 also includes a cross-cutting blade assembly 7 and a flipping assembly 8. The cross-cutting blade assembly 7 includes a blade head fixing plate 71 slidably connected to the lower surface of the linear slide module 6. A cylinder seat 72 is fixedly installed on the inner side wall of the blade head fixing plate 71, and a connecting plate 73 is connected to one end of the cylinder seat 72. A lead screw module is fixedly installed on the lower surface of the connecting plate 73, and a blade holder 74 is connected to the lower surface of the connecting plate 73 through the lead screw module. The flipping assembly 8 includes a flipping support 81 connected by a rodless cylinder. A linear slide rail is connected to the side of the flipping support 81 near the rodless cylinder. The flip support 81 is connected to clamping beams 82 on both sides of the linear slide rail. A flip lifting plate 83 is connected to one end face of the clamping beam 82. The front end of the blade holder 74 is equipped with a cutting motor. The blade holder 74 is movably connected to a saw blade 75 through the cutting motor. Limiting wheel seats 76 are connected to both sides of the blade holder 74. A wheel set 77 is connected to the bottom of one side surface of the limiting wheel seat 76 through a rotating shaft. The limiting wheel seats 76 on both sides are placed in the middle of the clamping beams 82 on both sides. A dust suction pipe 78 is fixedly installed at the front end of one of the limiting wheel seats 76.

[0036] After the battery assembly is clamped and fixed, the linear slide module 6 drives the cutter head fixing plate 71 to move directly above the battery assembly. The cylinder seat 72 inside the cutter head fixing plate 71 actuates, causing the connecting plate 73 to make a small horizontal adjustment. Through laser positioning sensor calibration, the cutter holder 74 at the bottom of the connecting plate 73 is precisely aligned with the preset transverse cutting line of the battery. After positioning, the lead screw module installed on the lower surface of the connecting plate 73 starts, driving the cutter holder 74 to make a linear feed motion along the width direction of the battery at a uniform speed. At the same time, the cutting motor fixed at the front end of the cutter holder 74 drives the saw blade cutter 75 to rotate at high speed, performing high-precision transverse cutting of the battery assembly. During the cutting process, the feed speed and the saw blade speed are matched to avoid problems such as saw blade jamming and shell chipping, and the battery is separated from the shell.

[0037] During the cutting process, the wheel sets 77 on the symmetrically mounted limit wheel seats 76 on both sides of the tool holder 74 roll closely against the high-precision guide surface of the clamping beam 82, providing bidirectional guidance and limiting for the feed movement of the tool holder 74, ensuring the straightness of the cutting trajectory. At the same time, the dust suction pipe 78 fixed on one side of the limit wheel seat 76 starts the negative pressure dust suction mode, with the dust suction port close to the cutting area, collecting aluminum alloy dust and aluminum chips generated during cutting in real time, preventing dust from adhering to the battery casing, cell surface or equipment guide rail, ensuring the stability of the subsequent core extraction process and extending the service life of the equipment.

[0038] Reference Figure 10 and Figure 11 A power shaft 84 is connected to the middle of one end face of the tilting lifting plate 83. A hyperboloid reduction motor is fixedly installed at one end of the power shaft 84. A transmission gear A85 is fixedly installed at the end of the power shaft 84 away from the motor. A tilting bracket 87 is movably connected to both sides of the transmission gear A85 through bearings. A pressure cover 86 is sleeved on the middle of both sides of the tilting bracket 87. An active rotating shaft is connected through the inner wall of one of the pressure covers 86. A transmission gear B88 is meshed with the upper surface of the transmission gear A85. A clamping beam 82 is fixedly installed on the middle of one side of the transmission gear B88. A clamping bar 821 is connected to the inner wall of the clamping beam 82.

[0039] After the transverse cutting is completed, the flipping component 8 initiates the posture adjustment process, flipping the battery assembly to a position where the interface between the cell and the casing faces upwards. This facilitates the precise separation of the cell by the core extraction unit 4. The hyperboloid geared motor fixed on the flipping support 81 drives the power shaft 84 to rotate at a constant speed. The end of the power shaft 84 rotates synchronously through the transmission gear A85 connected by a flat key. Through gear meshing, the transmission gear B88 is driven to rotate in the opposite direction, thereby driving the clamping beam 82 fixed to the transmission gear B88 and the battery assembly to rotate smoothly. The flipping angle can be precisely set by an angle sensor until the interface between the cell and the casing faces upwards and remains horizontal. During this process, the flipping support 81 can be slightly adjusted in the horizontal direction through the cooperation of the rodless cylinder and the linear slide rail to adapt to the flipping requirements of blade batteries of different lengths and specifications, improving the versatility of the device.

[0040] Reference Figure 12 and Figure 13 The core extraction unit 4 includes a thin external gear cylinder seat 41 fixedly installed on the lower surface of the linear slide module 6. One end of the thin external gear cylinder seat 41 is fixedly connected to a thrust block 42. A connecting seat is fixedly installed on the lower surface of the thrust block 42. A core extraction frame 44 is fixedly installed on the lower surface of the connecting seat. A core extraction pusher seat 45 is connected to the lower surface of the core extraction pusher seat 44. A pusher shell assembly 46 is connected to the inner side wall of the core extraction pusher seat 45. The pusher shell assembly 46 includes a cylinder mounting seat 461 connected to the inner side of the core extraction pusher seat 45. A three-rod cylinder is connected to the back of the cylinder mounting seat 461. A two-rod cylinder is connected to the lower surface of the cylinder mounting seat 461. One end of the two-rod cylinder is connected to a pusher shell plate 462. There are several pusher shell plates 462, which are evenly distributed on the core extraction frame 44 in a horizontal array.

[0041] After the battery assembly is flipped to the set posture and stabilized, the core extraction unit 4 starts the cell extraction process. The array-type push structure is used to achieve non-destructive separation of the cell from the casing, ensuring the integrity of the cell to meet the needs of subsequent testing or recycling.

[0042] The linear slide module 6 drives the thin external gear cylinder seat 41 to move directly above the flipping station. After the posture and position of the battery assembly are confirmed by the vision sensor, the piston rod of the thin external gear cylinder seat 41 extends and pushes the thrust block 42 and the core retrieval frame 44, which is fixed to it by bolts, to move downward. The movement stroke is precisely controlled by the displacement sensor, so that the core retrieval pusher seat 45 at the bottom of the core retrieval frame 44 is precisely aligned with the end face of the battery assembly. The reference surface of the core retrieval pusher seat 45 and the end face of the cell maintain a high degree of parallelism, ensuring that the subsequent pushing operation is evenly stressed.

[0043] The three-bar cylinder on the cylinder mounting seat 461 inside the core ejector 45 first actuates, driving the pusher assembly 46 to make a small horizontal adjustment, so that the positions of several pusher plates 462 correspond one-to-one with the inner wall of the battery casing, and the center of the pusher plate 462 coincides with the central axis of the battery cell. Subsequently, the two-bar cylinder drives all the pusher plates 462 to extend synchronously in an array. The extension speed is divided into two stages. The pusher plates 462 apply a uniform pushing force against the end face of the battery cell, slowly and smoothly pushing the battery cell out of the cut half-shell casing. During the pushing process, the pushing force is transmitted through a pressure sensor. The device monitors in real time. If an abnormal thrust occurs, the system will immediately stop and alarm to prevent the battery cell from being damaged by pressure, thus achieving non-destructive extraction of the battery cell. After the battery cell is completely ejected, it is smoothly received by the external conveying mechanism on the side of the core extraction frame 44 and transferred to the subsequent battery cell testing, sorting or recycling process. At the same time, the clamping bar 821 on the inner side of the clamping beam 82 retracts under the drive of the micro cylinder, releasing the battery casing. The casing falls into the pre-set collection box under the flipping frame under the action of gravity, realizing the orderly separation of battery cell and casing, which facilitates the centralized recycling and processing of the casing in the future.

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.
