Description

Technical Field

[0001] The present invention belongs to the technical field of sawing devices, and more specifically, relates to a sawing device for special-shaped lithium battery shells with a cooling and lubricating structure. Background Art

[0002] In the field of lithium battery manufacturing, it is often necessary to use a sawing device to process the special-shaped shells of lithium batteries. For example, during the assembly process of lithium batteries, in order to make the shell meet specific size and shape requirements, manufacturers often use a sawing process. At this time, it is necessary to use a sawing device to cut the special-shaped shell of the lithium battery to facilitate the subsequent battery assembly process.

[0003] However, when sawing the irregularly shaped lithium battery casings, the high-speed friction between the saw blade and the casing material often causes a large amount of heat to accumulate, causing the saw blade temperature to rise sharply. However, traditional sawing devices usually use cutting fluid to directly cool the saw blade. As a result, during the actual sawing process, due to the difficulty in controlling the cutting fluid spray position, a large amount of cutting fluid will splash everywhere. After the splashing cutting fluid mixes with the cutting debris, it easily makes the work area dirty and difficult to clean. This not only affects the cleanliness of the production environment and makes it inconvenient to manage the production site, but also increases labor and time costs due to frequent cleaning of the work area, thereby reducing production efficiency.

DETAILED DESCRIPTION

[0048] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but are not intended to limit the scope of protection of the present invention.

[0049] Example:

[0050] like Figures 1 to 10 As shown, the present invention provides a lithium battery special-shaped shell sawing device with a cooling and lubrication structure, including a base 11, a sliding mechanism and a cutting plate 12 are provided on the base 11, the cutting plate 12 is slidably connected to the base 11 through the sliding mechanism, and the cutting plate 12 is provided with a clamping assembly for clamping the battery shell, the clamping assembly includes two groups of adaptive clamping plates 21 and two groups of fixed plates 22, and the adaptive clamping plates 21 are connected to the fixed plates 22 through adjusting members.

[0051] By connecting two sets of adaptive clamping plates 21 and a fixed plate 22 via an adjustment member, the clamping assembly can adjust the clamping spacing based on the size of the irregularly shaped lithium battery casing, improving the device's adaptability to casings of varying specifications. During cutting, the adaptive clamping plates 21 conform to the casing and, in conjunction with the adjustment member, ensure stability and cutting accuracy. Furthermore, this structure is easy to operate, reducing operator labor and skill requirements, and improving clamping and production efficiency.

[0052] The base 11 is provided with a receiving groove 111, and a protective cover 112 is provided above the receiving groove 111. The protective cover 112 is installed on the base 11, and a support frame 13 is provided on the protective cover 112. A driving component is slidingly provided on the support frame 13. The driving component includes a rotating cylinder 31 and a first driving motor 32. The first driving motor 32 is installed at the bottom of the rotating cylinder 31, and a saw blade 41 is sleeved on the output shaft of the first driving motor 32.

[0053] The provision of the receiving groove 111 provides space for collecting debris and waste liquid generated during the cutting process, which facilitates subsequent unified processing and maintains the cleanliness of the work area. The provision of the protective cover 112 can block debris that may splash out during cutting, ensure the safety of the operator, and prevent external debris from entering and affecting the cutting work. The support frame 13 provides a stable support structure for the drive assembly to ensure its stability during operation. In the drive assembly, the rotary cylinder 31 can adjust the angle of the saw blade 41 by receiving the signal from the control module 63 to meet the diverse cutting requirements of the special-shaped shells of lithium batteries. The first drive motor 32 provides power to the saw blade 41 by receiving the signal from the control module 63 to ensure the progress of the cutting process. This overall layout and component coordination improves the functionality, safety and cutting efficiency of the device to adapt to the complex task of sawing special-shaped shells of lithium batteries.

[0054] The support frame 13 is also provided with a cooling assembly, which includes a three-way nozzle 51 and a mounting frame 52. The mounting frame 52 is slidably connected to the support frame 13. The three-way nozzle 51 is installed on the mounting frame 52 and faces the saw blade 41.

[0055] The mounting frame 52 is slidably connected to the support frame 13, giving the three-way nozzle 51 the flexibility to adjust its position so that it can adapt to the position changes of the saw blade 41 during different cutting operations. The three-way nozzle 51 is installed on the mounting frame 52 and faces the saw blade 41. It can directly deliver cutting fluid to the working area of ​​the saw blade 41. Through multi-angle spraying, it removes the heat generated by the friction between the saw blade 41 and the special-shaped shell of the lithium battery, and plays a cooling and lubricating role on the saw blade 41. This setting helps to maintain the stable performance of the saw blade 41, reduce the wear of the saw blade 41 caused by overheating and the deviation of the cutting accuracy, ensure the stability and continuity of the sawing process, and thus improve the overall quality and efficiency of the sawing of the special-shaped shell of the lithium battery.

[0056] like Figures 2 to 4As shown, the saw blade 41 comprises a base 411 and teeth 412 evenly distributed along the edge of the base 411. A cutting head 413 is mounted on the teeth 412, and a first chip removal groove 414 and a second chip removal groove 415 are located between adjacent teeth 412. This arrangement optimizes the cutting and chip removal performance of the saw blade 41. The base 411 serves as the main structure of the saw blade 41, providing support for all components and ensuring the overall strength and stability of the saw blade 41. The teeth 412 evenly distributed along the edge of the base 411, in conjunction with the cutting head 413, are capable of cutting even the irregularly shaped lithium battery casings. The first and second chip removal grooves 414, 415, located between adjacent teeth 412, facilitate the removal of larger debris during the cutting process, preventing it from accumulating in the cutting area and affecting the cutting effect. The second chip removal grooves 415 assist in removing smaller debris and, in conjunction with the first chip removal grooves 414, optimize the chip removal path. The chip removal efficiency of the saw blade 41 is improved, the interference of debris on cutting is reduced, and the smooth cutting is ensured, thereby improving the cutting quality and efficiency of the sawing device on the special-shaped shell of the lithium battery.

[0057] Both sides of the base 411 are provided with collecting grooves 416 and multiple groups of guide grooves 417. The collecting groove 416 is located at the end away from the saw teeth 412. The second chip groove 415 is located in the transition area between the root of the saw teeth 412 and the center of the base 411. The first chip groove 414 is a U-shaped groove, which is opened between the roots of adjacent saw teeth 412.

[0058] During the sawing process, the collecting grooves 416 and the guide grooves 417 on both sides of the base 411 cooperate with each other. The collecting groove 416 is set at the end away from the saw teeth 412, so that the cutting fluid and debris are concentrated in this area under the action of centrifugal force. Multiple groups of guide grooves 417 are radially distributed with the center of the base 411 as the origin, and one end extends to the edge of the groove of the second chip groove 415. They can guide the cutting fluid and debris discharged from the second chip groove 415 to the collecting groove 416. The first chip groove 414 is a U-shaped groove, which is opened between the tooth roots of adjacent saw teeth 412. It is conducive to quickly collecting the debris generated at the tooth roots during cutting, and cooperates with the second chip groove 415 and the guide groove 417 to ensure the orderly flow of debris and cutting fluid.

[0059] The bottom of the second chip groove 415 is an arc-shaped surface, and the notch is a trapezoidal surface. The angle between the notch of the trapezoidal surface and the radial plane of the base 411 is α, and α∈15° to 45°. The arc-shaped groove bottom helps to reduce the resistance of the debris to the flow in the groove, so that the debris can move more smoothly along the bottom of the groove. The trapezoidal notch increases the notch area, which is convenient for collecting more debris generated from the cutting part. The angle α between the trapezoidal notch and the radial plane of the base 411 is limited to 15° to 45° after optimization consideration. Within this angle range, it can ensure that during the rotation of the saw blade 41, the centrifugal force is used to throw the debris into the guide groove 417, and then enter the collecting groove 416 to achieve chip removal. It can also ensure that the cutting fluid, under the action of this structure, evenly covers the working area of ​​the saw blade 41, enhances the cooling and lubrication effect, and ultimately improves the cutting performance and service life of the saw blade 41.

[0060] The collecting groove 416 is annular and surrounds the central mounting hole of the base 411. The guide grooves 417 are streamlined and radially distributed from the center of the base 411. One end of the guide groove 417 extends to the edge of the notch of the second chip removal groove 415, and the other end is connected to the collecting groove 416.

[0061] A chip removal and cutting fluid collection path is constructed for the saw blade 41. The collecting groove 416 is annularly surrounding the central mounting hole of the base 411. This layout can collect cutting fluid and debris coming from different directions. The guide groove 417 adopts a streamlined setting and is radially distributed. One end is connected to the second chip removal groove 415, and the other end is connected to the collecting groove 416. The centrifugal force generated by the rotation of the saw blade 41 can guide the chips and cutting fluid generated during the cutting process along the streamlined groove body of the guide groove 417, from the second chip removal groove 415 to the collecting groove 416. This structure avoids the disorderly splashing or accumulation of chips and cutting fluid on the saw blade 41, ensures the cleanliness of the cutting area of ​​the saw blade 41, maintains the stable performance of the saw blade 41, and thereby improves the stability and cutting efficiency of the sawing process.

[0062] Specifically, when the saw blade 41 rotates at high speed to cut the irregular-shaped lithium battery casing, the resulting debris varies in size. Larger debris is initially caught by the first chip removal groove 414. Using the centrifugal force generated by the rotation of the saw blade 41, it escapes from the cutting area, thus preventing it from obstructing subsequent cutting. Meanwhile, smaller debris more easily enters the second chip removal groove 415. Thanks to its curved groove bottom and trapezoidal notch, small debris flows smoothly within the groove, and the larger notch area captures more of this type of debris.

[0063] Regarding the role of the cutting fluid, a portion of the cutting fluid delivered to the saw blade 41 directly acts on the cutting point, reducing the cutting temperature. The remaining portion, similarly affected by centrifugal force as the saw blade 41 rotates, moves along with the debris. This ensures that the cutting fluid is evenly distributed across the working area of ​​the saw blade 41, enhancing the cooling and lubricating effect. The cutting fluid, carrying debris, then flows orderly along the guide groove 417 to the collecting groove 416. The collecting groove 416 temporarily collects the cutting fluid and debris for subsequent centralized processing, further ensuring stable sawing operations.

[0064] like Figure 2 、 3 As shown in Figures 5 and 6, the cooling assembly also includes a saw blade cover 42. The saw blade cover 42 is a semi-enclosed arc-shaped shell that is sleeved on the outside of the saw blade 41, and its opening direction is consistent with the rotation and cutting direction of the saw blade 41. The saw blade cover 42 of the semi-enclosed arc-shaped shell is sleeved on the outside of the saw blade 41, which can block the splashing of debris generated during the sawing process, ensuring the safety of the operator and the surrounding equipment from being damaged by debris. Its opening direction is consistent with the rotation and cutting direction of the saw blade 41, and the airflow generated by the rotation of the saw blade 41 can be used to guide the debris and waste liquid generated by the cutting to be discharged along the opening direction, thereby preventing the debris and waste liquid from being scattered disorderly around the saw blade 41 and maintaining the cleanliness of the working area.

[0065] The saw blade cover 42 is mounted on the first drive motor 32. Water guide ports 421 are provided on both sides of the saw blade cover 42. The water outlet ends of the three-way nozzle 51 are respectively connected to the water guide ports 421. The saw blade cover 42 is mounted on the first drive motor 32 so that the relative positions of the saw blade cover 42 and the saw blade 41 remain stable, ensuring that the saw blade 41 is covered during the cooling process. Water guide ports 421 are provided on both sides of the saw blade cover 42 and are connected to the water outlet pipes of the three-way nozzle 51, so as to evenly transport the cutting fluid to the inside of the saw blade cover 42. In this way, the cutting fluid can act on the saw blade 41 from both sides of the saw blade 41 at the same time, ensuring the uniformity of cooling, maximizing the cooling and lubricating effect, reducing the working temperature of the saw blade 41, reducing wear, improving cutting accuracy, and optimizing the flushing and diversion effects of debris and waste liquid, maintaining a clean sawing environment.

[0066] The inner wall of the saw blade cover 42 is provided with a plurality of guide ridges 422 , which are spirally distributed along the rotation direction of the saw blade 41 . Guide plates 423 for draining the waste cutting fluid are provided at both ends of the saw blade cover 42 .

[0067] The multiple groups of guide ridges 422 on the inner wall of the saw blade cover 42 are distributed in a spiral shape along the rotation direction of the saw blade 41. When the saw blade 41 is running at high speed, they can change the flow path of the cutting fluid and debris, prompting them to move more orderly along the spiral trajectory. This not only enhances the cooling coverage effect of the cutting fluid on the saw blade 41, but also helps the debris to quickly converge in a specific direction. The guide blades 423 at both ends of the saw blade cover 42 can guide the discharge of cutting waste fluid, preventing waste fluid from accumulating in the saw blade cover 42, maintaining the cleanliness of the saw blade 41 cutting environment, further ensuring the cutting performance and service life of the saw blade 41, and improving the working efficiency and stability of the entire sawing device.

[0068] Two sets of guide plates 14 are installed within the receiving tank 111, each with multiple sets of guide protrusions 141 on its surface. These plates redirect the flow of cutting fluid and debris within the receiving tank 111, directing them to specific locations for centralized collection and processing. The guide protrusions 141 on the surfaces of the plates 14 increase friction between the fluid and the surfaces, promoting a more orderly flow of cutting fluid and debris, preventing their disorderly diffusion within the receiving tank 111. These protrusions also facilitate the sedimentation of debris, improving the recycling rate of the cutting fluid, maintaining the cleanliness of the receiving tank 111, and ensuring the continuous and stable operation of the sawing device.

[0069] like Figure 1 、 2 As shown in Figures 3, 4, 8, 9, and 10, a seepage hole 121 is provided on the cutting plate 12, and a spiral guide column 15 and a filter plate 16 are provided under the guide plate 14. The spiral guide column 15 and the filter plate 16 are both tilted in the receiving groove 111, and a chip discharge port 113 is provided on the base 11, which faces the spiral guide column 15. The seepage hole 121 on the cutting plate 12 allows the cutting fluid and the fine debris carried by the cutting process to seep smoothly into the receiving groove 111. The tilted spiral guide column 15 and the filter plate 16 optimize the waste liquid and debris treatment process in the receiving groove 111. When the spiral guide column 15 rotates, it can push heavier debris along its spiral trajectory to the chip discharge port 113 to realize automatic chip removal; the filter plate 16 filters the seeping cutting fluid, separates the fine impurities remaining therein, and ensures the cleanliness of the cutting fluid. The inclined layout is conducive to the natural sliding of waste liquid and debris under the action of gravity, thereby improving processing efficiency. The chip discharge port 113 faces the spiral guide column 15, which facilitates the discharge of debris pushed by the spiral guide column 15 and avoids the accumulation of debris in the receiving groove 111, ensuring the continuous and stable sawing work, and facilitating the recycling and reuse of the cutting fluid.

[0070] The spiral guide column 15 is provided with a continuous spiral blade 151. The two ends of the spiral guide column 15 are rotatably connected to the side wall of the receiving groove 111 through a bearing seat. A second drive motor 17 is provided on one side of the base 11. The output shaft of the second drive motor 17 is connected to one end of the spiral guide column 15. The continuous spiral blade 151 on the spiral guide column 15 can push the debris to move along a spiral trajectory when it rotates. The two ends are rotatably connected to the side wall of the receiving groove 111 through a bearing seat, thereby ensuring the stability of the rotation of the spiral guide column 15. The second drive motor 17 provides power for the rotation of the spiral guide column 15 by receiving a signal from the control module 63, so that the debris can be continuously and stably transported to the chip discharge port 113 for discharge, reducing the frequency of manual cleaning and improving the degree of automation and work efficiency of the sawing device.

[0071] A liquid outlet is provided at the bottom of the receiving tank 111, and a filter device 61 and a water pump 62 are provided on one side of the base 11. The liquid outlet is connected to the three-way nozzle 51 through a pipeline, and the filter device 61 and the water pump 62 are installed on the connecting pipeline. The liquid outlet at the bottom of the receiving tank 111 is connected to the three-way nozzle 51 through a pipeline, and the filter device 61 and the water pump 62 are installed on the connecting pipeline. The filter device 61 can filter the cutting fluid flowing out of the receiving tank 111, remove impurities therein, and ensure the cleanliness of the cutting fluid. The water pump 62 is powered by receiving a signal from the control module 63, and re-delivers the filtered cutting fluid to the three-way nozzle 51, so that it can cool and lubricate the saw blade 41 again, forming a circulation loop of the cutting fluid, saving resources, reducing production costs, and ensuring the continuous sawing work.

[0072] A control module 63 is installed on the base 11, a temperature sensor 64 is installed on the saw blade cover 42, and a flow control valve 65 is installed on one side of the three-way nozzle 51. The control module 63 is electrically connected to the temperature sensor 64 and the flow control valve 65. The temperature sensor 64 on the saw blade cover 42 monitors the temperature around the saw blade 41 and feeds the temperature signal back to the control module 63. Based on the received temperature signal, the control module 63 adjusts the flow control valve 65 on one side of the three-way nozzle 51. When the temperature of the saw blade 41 rises, the control module 63 increases the opening of the flow control valve 65, allowing more cutting fluid to be sprayed onto the saw blade 41, enhancing the cooling effect. When the temperature drops, the control module 63 decreases the opening of the flow control valve 65 to control the flow of cutting fluid, ensuring that the saw blade 41 always remains within the appropriate operating temperature range, thereby improving the service life and cutting quality of the saw blade 41. The control module 63 can be a SIMATIC IPC427E industrial computer, and the temperature sensor 64 can be a Raytek MX2 infrared temperature sensor.

[0073] The sliding mechanism includes a slide rail 71 provided on the base 11. A slider 72 slides within the slide rail 71. The top of the slider 72 is connected to the bottom of the cutting board 12. The slide rail 71 provided on the base 11 cooperates with the slider 72, allowing the cutting board 12 to slide smoothly on the slide rail 71. The top of the slider 72 is connected to the bottom of the cutting board 12, ensuring a stable connection between the two. This structure allows the cutting board 12 to be flexibly moved as needed during the sawing process, meeting different cutting position requirements, while also improving the stability and precision of the cutting process.

[0074] like Figures 1 to 10 As shown, a transmission rod 73 is provided in the slide rail 71, and a third drive motor 74 is provided on one side of the base 11. The output shaft of the third drive motor 74 is connected to one end of the transmission rod 73, and the slider 72 is sleeved on the transmission rod 73. Power drive is provided for the movement of the slider 72. The transmission rod 73 provided in the slide rail 71 rotates when the third drive motor 74 receives the signal from the control module 63. The third drive motor 74 is installed on one side of the base 11, and its output shaft is connected to one end of the transmission rod 73 to transmit power to the transmission rod 73. The slider 72 is sleeved on the transmission rod 73. When the transmission rod 73 rotates, the slider 72 is driven to move in the slide rail 71 through threaded engagement, thereby realizing the position adjustment of the cutting plate 12, so that the sawing device can adapt to the cutting requirements of lithium battery special-shaped shells of different sizes and shapes, and improve the versatility and operational convenience of the device.

[0075] First guide rods 75 are provided on both sides of the slider 72. The ends of the first guide rods 75 are mounted on the protective cover 112 and the base 11 via bearing blocks, respectively. The cutting plate 12 is mounted on the two sets of first guide rods 75. This further enhances the stability of the movement of the cutting plate 12. The first guide rods 75 on both sides of the slider 72 are mounted on the protective cover 112 and the base 11 via bearing blocks, respectively, providing additional guiding support for the movement of the cutting plate 12. The cutting plate 12 is mounted on the two sets of first guide rods 75, preventing it from shaking or shifting as it moves along the slide rail 71. This ensures the accuracy of the cutting position, helps improve cutting quality, and also extends the service life of the cutting plate 12 and related components.

[0076] Two sets of fixed plates 22 are symmetrically arranged on either side of the cutting plate 12. The adjusting members include a rotating rod 76 and two sets of second guide rods 81, which are pierced through the fixed plates 22. This provides a structural foundation for adjusting the adaptive clamping plate 21. Two sets of fixed plates 22 are symmetrically arranged on either side of the cutting plate 12. The rotating rod 76 and two sets of second guide rods 81 are pierced through the fixed plates 22. One end of the rotating rod 76 is connected to the fixed plates 22 via a bearing, enabling rotational adjustment to facilitate adjustment of the angle of the adaptive clamping plate 21. One end of the second guide rod 81 is connected to the fixed plate 22 to provide guidance for the movement of the adaptive clamping plate 21. This structure enables the adaptive clamping plate 21 to be adjusted according to the shape and size of the material being cut, enhancing the applicability of the clamping assembly.

[0077] One end of the rotating rod 76 is connected to the fixed plate 22 through a bearing, and one end of the second guide rod 81 is connected to the fixed plate 22. Two groups of springs 82 are provided between the fixed plate 22 and the adaptive splint 21. The two groups of springs 82 are respectively mounted on the two groups of second guide rods 81.

[0078] This arrangement imparts a certain degree of elastic clamping capability to the adaptive clamping plate 21. Two sets of springs 82, positioned between the fixed plate 22 and the adaptive clamping plate 21, are respectively mounted on two sets of second guide rods 81. When the material being cut is placed, the elastic force of the springs 82 allows the adaptive clamping plate 21 to conform to the material surface, providing a stable and appropriate clamping force. This elastic clamping method not only ensures that the material does not loosen during the cutting process, but also prevents damage to the material due to excessive clamping force, thereby improving cutting stability and product quality.

[0079] The clamping assembly also includes two sets of limit plates 83. Two sets of guide plates 84 are provided at each end of the cutting plate 12, each with a first slot 841. The limit plates 83 are slidably connected to the cutting plate 12 via the first slots 841. Both sets of guide plates 84 have adjustment slots, each fitted with fixing bolts 85. These fixing bolts 85 are connected to the limit plates 83, enabling the adaptive clamping plate 21 to be adjusted and fixed. The first slots 841 at each end of the cutting plate 12 allow the limit plates 83 to slide on the cutting plate 12 to accommodate materials of varying lengths. The adjustment slots on the guide plates 84 engage the fixing bolts 85. Once the limit plates 83 have slid to the desired position, the fixing bolts 85 are tightened to secure them to the guide plates 84. This limits the range of movement of the adaptive clamping plate 21, ensuring a stable clamping effect for materials of varying sizes. This further enhances the versatility and reliability of the clamping assembly.

[0080] A supporting boss 86 is also provided on the cutting plate 12, and a cutting groove 861 is provided on the supporting boss 86 and the limiting plate 83. A heat dissipation fin 87 and two sets of heat dissipation fans 88 are provided on one side of the limiting plate 83. A plurality of ventilation holes 831 are provided on one side of the limiting plate 83, and an air exchange groove 832 is provided on the top of the limiting plate 83. The ventilation holes 831 are connected to the air exchange groove 832.

[0081] This arrangement further enhances the functionality of the cutting plate 12 and the stopper plate 83 during the cutting process. The support boss 86 on the cutting plate 12 and the cutting groove 861 on the stopper plate 83 provide positioning and support for the cutting operation. The support boss 86 helps stabilize the material being cut, ensuring stability during cutting and reducing vibration, thereby improving cutting accuracy. The cutting groove 861 guides the cutting path, ensuring a more standardized cutting operation, avoiding cutting deviations, and ensuring cutting quality.

[0082] The heat dissipation fins 87 and two sets of heat dissipation fans 88 arranged on one side of the limit plate 83, together with the ventilation holes 831 and the air exchange slots 832, form a set of heat dissipation structure. During the cutting process, the heat generated will be transferred to the limit plate 83, and the heat dissipation fins 87 will increase the heat dissipation area and accelerate the heat dissipation. The heat dissipation fan 88 operates by receiving the signal of the control module 63, accelerates the air flow, discharges the hot air through the ventilation holes 831, and exchanges it with the outside cold air through the air exchange slots 832. Multiple sets of ventilation holes 831 increase the air circulation efficiency, enhance the heat dissipation effect, and can timely reduce the temperature of the limit plate 83 and the surrounding area to avoid overheating affecting the cutting accuracy, damaging the material or shortening the service life of the equipment, and ensure that the cutting work is carried out continuously and stably.

[0083] The drive assembly also includes a sliding plate 91. Two sets of second sliding grooves 131 are provided on the top of the support frame 13. Screw rods 92 are passed through the second sliding grooves 131. Electric sliders 93 are mounted on the two sets of screw rods 92. The sliding plate 91 is slidably connected to the screw rods 92 through the two sets of electric sliders 93. A telescopic cylinder 94 is provided on the top of the sliding plate 91. The movable rod of the telescopic cylinder 94 passes through the sliding plate 91 and is connected to the rotating cylinder 31. This arrangement improves the flexibility and adjustability of the drive assembly. The two sets of second sliding grooves 131 on the top of the support frame 13 and the screw rods 92 passed through them, together with the electric sliders 93, enable the sliding plate 91 to move along the direction of the screw rods 92. The electric slider 93 is driven by receiving signals from the control module 63 to adjust the position of the sliding plate 91 to meet the requirements of different cutting positions, thereby expanding the working range of the sawing device in the horizontal direction.

[0084] A telescopic cylinder 94 is mounted on top of the sliding plate 91, with its movable rod extending through the sliding plate 91 and connected to the rotating cylinder 31. The telescopic cylinder 94 vertically adjusts the height of the rotating cylinder 31 and the saw blade 41 to accommodate cutting of various thicknesses of irregularly shaped lithium battery casings. The rotating cylinder 31 adjusts the angle of the saw blade 41. Combined with the horizontal and vertical adjustment of the telescopic cylinder 94 and the sliding plate 91, the saw blade 41 can be adjusted in multiple dimensions within the space, meeting the diverse cutting requirements of irregularly shaped lithium battery casings and improving the sawing device's processing adaptability and cutting accuracy.
