Technical Field
[0001] This invention relates to the field of laser cutting technology for battery tabs, and in particular to a laser cutting device and method for solid-state battery tabs. Background Technology
[0002] In the field of solid-state battery manufacturing, the tabs are the core components that connect the positive and negative electrodes of the battery to the external circuit. Their cutting precision and processing stability directly affect the energy storage performance, safety performance and production efficiency of the battery. As the new energy industry continues to increase its requirements for the energy density and mass production scale of solid-state batteries, the processing of tabs is gradually developing towards high speed and high precision. Laser cutting technology has become the mainstream technical solution for tab cutting due to its advantages such as non-contact processing, smooth cut, and small heat-affected zone. To meet the cutting requirements of electrode sheets operating at high speeds, Chinese Patent CN107999972B discloses a laser cutting device and method for electrode sheets. This device, through optimized structural design, can effectively reduce the generation of laser cutting waste during high-speed electrode sheet transmission, while suppressing electrode sheet vibration during cutting to ensure cutting accuracy. In addition, it effectively protects the core component, the galvanometer, allowing waste and dust generated during cutting to fall off and be discharged smoothly. It also has flexible production capabilities to adapt to cutting electrode sheets of different specifications, eliminating the need for frequent replacement of vacuum adsorption platforms. It shows significant advantages in improving processing efficiency and reducing maintenance costs, providing a feasible solution for the efficient processing of solid-state battery electrode sheets. However, in actual industrial applications, the above-mentioned devices and existing similar electrode laser cutting devices still have key technical shortcomings, which are mainly reflected in the design defects of the flue gas treatment process. During the laser cutting of electrode tabs, the electrode material generates a large amount of flue gas under high temperature, which is mixed with impurities such as metal dust and molten debris. If it cannot be treated in a timely and efficient manner, it will not only affect the workshop working environment, but also have an adverse effect on subsequent processes and equipment. At present, most of the existing electrode laser cutting devices only use simple smoke extraction pipes for flue gas collection, without setting up targeted pretreatment and efficient purification structures, resulting in poor flue gas treatment effect. Specifically, during the operation of the smoke extraction duct, large particles of impurities generated during cutting can easily enter the duct's interior directly. Over time, these particles accumulate on the inner wall of the duct, forming dust deposits that reduce the duct's diameter and affect the efficiency of flue gas flow. Simultaneously, capillary dust in the workshop environment and small debris from cutting processes can directly enter the subsequent flue gas purification system along with the flue gas. Since these impurities are not pre-treated by filtration, they can easily clog the filter elements of the purification system. This not only requires frequent maintenance and cleaning of the ducts and purification system, significantly increasing operating costs, but also disrupts production continuity due to equipment downtime, severely reducing overall production efficiency. More seriously, if the filtration system becomes clogged and is not detected in time, the flue gas cannot be effectively purified and discharged, allowing it to diffuse into the production workshop. This not only pollutes the working environment and endangers the health of operators, but may also affect the cleanliness of the electrode surface due to dust diffusion, thereby reducing the quality of electrode processing and even causing safety hazards such as internal short circuits in the battery, threatening the mass production quality of solid-state batteries.

The outer end of the connecting frame is fixedly connected to the bottom of the synchronous belt, and the upper end of the connecting frame is movably connected to the inside of the top rail frame.
[0013] A method for laser cutting solid-state battery tabs includes the following steps: Step 1: Install the linear motion module in the fixture slot of the cutting workbench via the fixture mounting base. Install the corresponding type of electrode pneumatic fixture on the top of the linear motion module. Place the electrode workpiece to be cut on the electrode pneumatic fixture and fix the electrode workpiece with the electrode pneumatic fixture. Multiple fixture mounting bases are distributed at equal intervals along the fixture slot to form multiple workstations. Complete the loading and clamping of one workstation, and prepare for loading of the other workstations simultaneously. Step 2: Start the linear movement module to move the pneumatic clamp and workpiece along the front-back direction, and move the workpiece to the cutting area directly below the laser cutting head. At the same time, start the transverse movement mechanism to drive the entire cutting mechanism to move and adjust the cutting position along the left-right direction. After the drive motor starts, it drives the synchronous belt through the synchronous pulley. The synchronous belt drives the slider along the guide rail through the connecting frame, thereby driving the mounting motherboard and the entire cutting mechanism to move synchronously left and right. Step 3: Start the cutting module and drive the laser cutting head to move up and down in the vertical direction through the lifting electric cylinder to adjust the distance between the laser cutting head and the workpiece tab to a suitable cutting height; Step 4: The laser cutting head emits a laser to cut the workpiece with the electrode tab, and at the same time, the suction fan in the purification module is activated to create negative pressure inside the dust collection module; Step 5: The smoking assembly is aimed at the cutting area through the smoking pipe, and draws in the smoke and impurities generated during cutting. The large particles in the smoke are initially filtered through the dust filter inside the smoking pipe. Step Six: When the cutting mechanism moves left and right with the transverse movement mechanism, the main toothed ring meshes with the rack, causing the main slip ring to rotate along the outer side of the ring frame. The main slip ring drives the main bevel toothed ring to rotate, which in turn drives the transmission shaft to rotate through the bevel gear. The lower spur gear at the bottom of the transmission shaft meshes with the outer toothed ring, causing the auxiliary slip ring to slide along the ring track, which in turn drives the cleaning brush plate to rotate synchronously. The cleaning brush plate cleans the surface of the dustproof filter screen. Step 7: The flue gas filtered by the dust filter enters the annular flue pipe through the smoke extraction pipe. The annular flue pipe collects the flue gas and then transports it to the purification box through the connecting pipe. The purification box performs deep purification treatment on the flue gas. The purified gas is discharged by the suction fan. After the cutting is completed, the linear motion module drives the pneumatic clamp for the electrode tab and the cut electrode tab workpiece to leave the cutting area and move it to the unloading station for unloading. At the same time, the next station that has been clamped is moved to the cutting area for cutting operation by the linear motion module. Step 8: When the dust removal brush plate needs to be replaced or maintained, unscrew the mounting screws on the mounting rail, remove the mounting plate, and then replace or maintain the dust removal brush plate. When the purification module needs to be cleaned, unscrew the screws on the sealing door, open the inspection window, and clean and maintain the inside of the purification box. Assemble, inspect, and replace the components of each module through the detachable connection structure.
[0014] Compared with the prior art, the beneficial effects of the present invention are: Firstly, in this invention, during the application of this technical solution, by setting up a dedicated smoke extraction structure and a multi-stage filtration structure, the smoke generated by the laser cutting tab can be efficiently collected during use. At the same time, large particulate impurities in the smoke are effectively intercepted and filtered, preventing large particulate impurities from entering the subsequent pipelines and purification system, preventing dust accumulation on the inner wall of the pipeline and blockage of the purification system, thereby achieving the effect of stabilizing the smoke treatment process, reducing the frequency of filtration system maintenance, reducing manual maintenance costs, and ensuring the continuous and stable operation of the equipment. Secondly, in this invention, during the application of this technical solution, multiple suction ducts are set up to surround the laser cutting head, so that the cutting area can be wrapped in smoke during use, achieving uniform and comprehensive collection and treatment of smoke, avoiding local smoke escape. At the same time, the suction structure is coordinated with the linkage cleaning design, which can simultaneously clean the filter components, remove attached impurities in time, further improve the filtration smoothness and cleaning effect, ensure the continuous and stable smoke extraction efficiency, and enhance the overall efficiency of smoke treatment.

[0017] Please see Figures 1-10 The present invention provides a solid battery tab laser cutting device, including a chassis 1, a cutting worktable 4 fixedly installed on the top of the chassis 1, a mounting frame 3 fixedly installed on the rear side of the top of the cutting worktable 4, a transverse mechanism 2 fixedly installed on the top of the mounting frame 3, and a cutting mechanism 6 fixedly installed at the moving end of the transverse mechanism 2. The cutting mechanism 6 includes a mounting motherboard 61, a purification module 62 fixedly mounted on the upper end of the mounting motherboard 61, a cutting module 63 fixedly mounted on the front of the mounting motherboard 61, a dust suction module 64 fixedly mounted on the lower end of the mounting motherboard 61 on the side away from the horizontal movement module, and a dust removal module 65 provided at the bottom of the dust suction module 64. The vacuum module 64 includes a mounting arm 646, a transmission assembly 644, a smoke extraction assembly 645, and a rack 66. A ring-shaped frame 641 is fixedly mounted at the bottom of the mounting arm 646. A main slip ring 642 is rotatably and slidably mounted on the outer side of the ring-shaped frame 641. A main gear ring 643 is fixedly mounted on the outer side of the main slip ring 642. The rack 66 is fixedly mounted on the upper end of the mounting main frame 3 near the mounting main plate 61. The transmission assembly 644 is evenly spaced at the bottom of the ring-shaped frame 641. The smoke extraction assembly 645 is fixedly mounted on the bottom of the main frame 641. The main gear ring 643 is fixedly installed on the outer end of the transmission assembly 644 and meshes with the transmission assembly 644. The main mounting board 61 integrates a purification module 62, a cutting module 63, and a dust collection module 64, allowing each module to work collaboratively to complete the electrode laser cutting and fume treatment operations. During cutting, the lateral movement mechanism 2 drives the cutting mechanism 6 to move as a whole, adjusting the cutting position to suit the electrode processing requirements. The cutting module 63 performs laser cutting on the electrode, while the dust collection module... When the dust extraction module 64 is activated, it works in conjunction with the purification module 62 to process the fumes generated during cutting. During the operation of the dust extraction module 64, the main slip ring 642 can rotate along the outer side of the ring frame 641. Because the main toothed ring 643 meshes with the rack 66 fixed on the mounting frame 3, the main slip ring 642 will rotate synchronously when the cutting mechanism 6 moves with the transverse mechanism 2. The main slip ring 642 drives the smoke extraction component 645 to move through the transmission component 644, ensuring that the smoke extraction component 645 can accurately correspond to the cutting area for fume collection. The dust removal module 65 works synchronously at the bottom of the dust extraction module 64 to reduce the accumulation of impurities in the dust extraction module 64 and ensure that the smoke extraction channel is unobstructed. This integrated design allows the modules to work together in coordination, improving the synchronicity of fume collection and processing, and preventing the spread of fumes generated during cutting. At the same time, with the cooperation of the transmission component 644, rack 66, and main toothed ring 643, the smoke extraction component 645 can be adjusted without additional drive, simplifying the operation process and enhancing the stability and efficiency of the device.
[0018] Please see Figures 1-6The top center of the cutting worktable 4 has a clamping groove 5. Clamping mounting bases 7 are fixedly installed at equal intervals on the inner side of the clamping groove 5. The cutting module 63 includes a mounting base 631, which is screwed onto the side of the mounting main board 61 away from the transverse module. A lifting electric cylinder 632 is fixedly installed on the inner side of the mounting base 631. A laser cutting head 633 is screwed onto the bottom output end of the lifting electric cylinder 632. The laser cutting head 633 is slidably connected to the middle of the ring frame 641. The transmission assembly 644 includes... The assembly includes a main bevel gear ring 6441 and a mounting base arm 6442. A smoke extraction assembly 645 is fixedly mounted on the outer end of the mounting base arm 6442. The mounting base arms 6442 are evenly spaced and arranged in a ring shape, fixedly mounted on the bottom of the ring frame 641. A drive shaft 6443 is rotatably connected to the inner end of the mounting arm 6446. A bevel gear 6444 is fixedly mounted on the top of the drive shaft 6443. The bottom end of the drive shaft 6443 is connected to the dust removal module 65 to drive the dust removal module 65 to rotate. The main bevel gear ring 6441 is fixedly mounted on the bottom of the main slip ring 642. The bevel gear 6444 and the main bevel gear ring 6441 are meshed and connected. The smoke extraction assembly 645 includes a smoke extraction tube 6451 and an annular smoke tube 6452. The smoke extraction tube 6451 is fixedly installed on the outer end of the mounting base arm 6442, and the annular smoke tube 6452 is fixedly installed on the top of the smoke extraction tube 6451. A connecting pipe 6453 is fixedly installed on the top of the annular smoke tube 6452. The output end of the connecting pipe 6453 is connected to the purification module 62. Each smoke extraction tube 6451 is connected to the purification module 62 through the annular smoke tube 6452 and the connecting pipe 6453. The module 62 is connected, and a smoke bucket 6454 is fixedly installed at the bottom of the smoke pipe 6451. The dust removal module 65 is installed at the bottom of the smoke bucket 6454. A dust filter 6455 is installed on the inner side of the smoke bucket 6454 by screws. The smoke bucket 6454 has an inverted cone-shaped structure, and an annular negative pressure flow channel is formed between its inner wall and the annular frame 641. When the dust removal brush plate 657 rotates and cleans, the dust removal brush plate 657 is located within the negative pressure coverage area of the smoke bucket 6454, and the swept-off impurities are directly sucked into the annular negative pressure flow channel.By setting the clamping groove 5 and the clamping mounting base 7 with equal spacing on the inner side, the appropriate clamping structure can be stably installed during use, providing basic support for clamping the electrode workpiece. During the cutting operation, the lifting electric cylinder 632 on the mounting base 631 drives the laser cutting head 633 to rise and fall along the middle of the ring frame 641, adjusting the distance between the laser cutting head 633 and the electrode workpiece to adapt to the cutting requirements and ensure smooth cutting operation. When the main slip ring 642 rotates, it drives the bottom main bevel gear ring 6441 to rotate synchronously. The main bevel gear ring 6441 meshes with the bevel gear 6444 at the top of the transmission main shaft 6443, driving the transmission main shaft 6443 to rotate. The bottom end of the transmission main shaft 6443 drives the dust removal module 65 to rotate. The mounting base arm 6442 is arranged in a ring, and its outer end smoke extraction component 645 follows the transmission. Component 644 operates by collecting fumes from the cutting area via the smoke extraction bucket 6454. The fumes are initially filtered by the dust filter 6455 inside the smoke extraction bucket 6454 before entering the smoke extraction pipe 6451. The fumes collected in each smoke extraction pipe 6451 are then collected through the annular smoke extraction pipe 6452 and transported to the purification module 62 for processing via the connecting pipe 6453. The dust filter 6455 prevents impurities from entering subsequent pipelines. The dust removal module 65, working in conjunction with rotation, ensures unobstructed smoke extraction channels. The annularly distributed mounting arms 6442 and smoke extraction components 645 enhance the comprehensiveness of fumes collection. The lifting cylinder 632 drives the laser cutting head 633 to precisely lift and lower. The coordinated operation of the overall structure improves the synchronization and stability of cutting and fumes treatment, simplifies the work process, and reduces the impact of impurities on equipment operation.
[0019] Please see Figures 6-8The dust removal module 65 includes an annular rail 651, an external gear ring 652, and a lower spur gear 653.

The external gear ring 652 is fixedly installed on the outer side of the secondary slip ring 654. The lower spur gear 653 is fixedly installed at the bottom end of the transmission main shaft 6443. The lower spur gear 653 meshes with the outer side of the external gear ring 652. The mounting screw 658 is a screw with a knob. The purification module 62 includes a purification box 621, which is fixedly installed on the upper side of the mounting main board 61 away from the lifting cylinder 632.

One side input end of the purification box 621 is connected to the output end of the connecting pipe 6453. A maintenance window 623 is opened on the top of the purification box 621. A sealing door 624 is installed on the top of the maintenance window 623 by screws. The dust removal module 65 is set to cooperate with the purification module 62. This allows for simultaneous cleaning of impurities and purification of flue gas during use. When the drive shaft 6443 rotates, it drives the lower spur gear 653 at the bottom to rotate. The lower spur gear 653 meshes with the outer toothed ring 652 on the outer side of the auxiliary slip ring 654, driving the auxiliary slip ring 654 to slide along the annular rail 651. The auxiliary slip ring 654 drives the cleaning brush plate 657 on the mounting rail 655 and mounting plate 656 to move synchronously. The top bristles of the cleaning brush plate 657 slide against the filter surface of the dustproof filter 6455, achieving cleaning of the dustproof filter 6455. When the cleaning brush plate 657 needs replacement or maintenance, the mounting plate 656 can be removed from the mounting rail 655 by turning the mounting screw 658 with the knob. The operation is convenient and requires no additional tools. When the purification module 62 is operating, the suction... When the machine 622 starts, it creates a negative pressure inside the purification chamber 621. The flue gas, after preliminary filtration, enters the purification chamber 621 through the connecting pipe 6453. After the purification chamber 621 processes the flue gas, it is discharged by the suction fan 622. The maintenance window 623 on the top of the purification chamber 621 facilitates internal maintenance. The sealing door 624 ensures the airtightness of the purification chamber 621 after closing, preventing flue gas leakage. The close contact and cleaning of the dust removal brush 657 keeps the dust filter 6455 unobstructed, preventing impurities from accumulating and affecting flue gas collection. The mounting screw 658 with a knob simplifies the maintenance process of the dust removal components. The cooperation between the purification chamber 621 and the suction fan 622 ensures the flue gas treatment effect. The coordinated operation of the overall structure improves the stability and continuity of equipment operation and reduces the difficulty of operation and maintenance.

The outer end of the connecting frame 25 is fixedly connected to the bottom of the timing belt 223, and the upper end of the connecting frame 25 is movably connected to the inside of the top rail frame 21. The cutting mechanism 6 is moved by the transverse movement mechanism 2, so that the cutting position can be flexibly adjusted to adapt to the needs of tab processing. When the drive module 22 is operating, The drive motor 221 starts, causing the synchronous pulley 222 at one end of the top rail frame 21 to rotate. The synchronous pulley 222 drives the synchronous pulley 222 at the other end to rotate synchronously via the synchronous belt 223. During the rotation of the synchronous belt 223, it drives the connecting frame 25 fixedly connected to it to move. The upper end of the connecting frame 25 moves inside the top rail frame 21, and at the same time, it drives the mounting main plate 61 and the slider 24 at the bottom to slide along the guide rail 23. The guide rail 23 provides guidance for the slider 24, ensuring that the mounting main plate 61 and the cutting mechanism 6 remain stable during the movement and avoiding spillage. The current offset is achieved by the cooperation of the drive motor 221, synchronous pulley 222 and synchronous belt 223 to ensure stable power transmission. The linkage between the connecting frame 25, synchronous belt 223 and mounting main board 61 ensures the synchronicity of the movement. The cooperation between the guide rail 23 and slider 24 improves the accuracy and smoothness of the movement of the cutting mechanism 6. The overall structure operates stably and can accurately adjust the position of the cutting mechanism 6 to meet the needs of tab cutting at different positions. At the same time, it reduces the shaking during the movement, ensures the stability of the cutting operation, and reduces the impact of position offset on the processing.
[0021] A method for laser cutting solid-state battery tabs includes the following steps: Step 1: Workstation layout and workpiece clamping. The clamping groove 5 in the middle of the top of the cutting worktable 4 provides a fixed space for clamp installation. The clamping mounting base 7 is used to install the linear movement module. The top of the linear movement module is equipped with the corresponding type of pneumatic clamp for the tab according to the tab specifications. The operator places the tab to be cut on the pneumatic clamp. The pneumatic clamp achieves stable clamping of the tab workpiece through vacuum adsorption, pneumatic clamping, positioning pin limiting, or magnetic attraction. Multiple clamping mounting bases 7 are distributed at equal intervals along the clamping groove 5 to form multiple workstations. In the initial state, the loading and clamping of one workstation is completed, and the loading preparation of the other workstations is carried out simultaneously. Step 2: Workpiece delivery and positioning. The linear moving module is activated, driving the pneumatic clamps and workpieces on it to move along the front-back direction, moving the workpiece to be cut to the cutting area directly below the laser cutting head 633. At the same time, the transverse moving mechanism 2 is activated, driving the cutting mechanism 6 to move along the left-right direction to adjust the cutting position. In the transverse moving mechanism 2, the top rail frame 21 provides installation support for the drive module 22 and the guide rail 23. After the drive motor 221 is activated, it drives the synchronous belt 223 through the synchronous wheel 222. The synchronous belt 223 drives the slider 24 to slide along the guide rail 23 through the connecting frame 25, thereby driving the mounting main board 61 fixedly connected to the slider 24 and the entire cutting mechanism 6 to move synchronously left and right. The mounting main frame 3 provides overall installation support for the transverse moving mechanism 2 and the cutting worktable 4. The mounting main board 61 realizes the integrated installation of the purification module 62, the cutting module 63, and the dust collection module 64. Step 3: Cutting height adjustment. After positioning, the cutting module 63 is started. The mounting base 631 provides fixed support for the lifting cylinder 632. The lifting cylinder 632 drives the laser cutting head 633 to move up and down in the vertical direction, adjusting the distance between the laser cutting head 633 and the workpiece to a suitable cutting height, in preparation for precise cutting. Step 4: Laser cutting is carried out. The laser cutting head 633 emits a laser to cut the tab workpiece. At the same time, the suction fan 622 in the purification module 62 is started, creating negative pressure inside the dust collection module 64 to provide power for the collection of flue gas. Step 5: Preliminary collection and filtration of smoke. In the dust collection module 64, the mounting arm 646 provides fixed support for the ring frame 641. The ring frame 641 is set around the laser cutting head 633. The smoke collection component 645 at its bottom is aligned with the cutting area through the smoke collection bucket 6454 to suck in the smoke and impurities generated during cutting. The dust filter 6455 inside the smoke collection bucket 6454 performs preliminary filtration of large particulate impurities in the smoke, preventing large particulate impurities from entering the subsequent pipeline. Step Six: Synchronous dust removal operation. When the cutting mechanism 6 moves left and right with the transverse mechanism 2, the main toothed ring 643 meshes with the rack 66 fixed on the main mounting frame 3, driving the main slip ring 642 to rotate along the outer side of the ring frame 641. When the main slip ring 642 rotates, its bottom main bevel toothed ring 6441 rotates synchronously, driving the transmission main shaft 6443 to rotate through the bevel gear 6444. The lower spur gear 653 at the bottom of the transmission main shaft 6443 meshes with the outer toothed ring 652, driving the secondary slip ring 654 to slide along the ring rail 651, thereby driving the mounting rail frame 655 and the dust removal brush plate 657 on the mounting plate 656 to rotate synchronously. The brush bristles on the top of the dust removal brush plate 657 are in contact with the filter surface of the dustproof filter screen 6455. During the rotation, the surface of the dustproof filter screen 6455 is cleaned to remove the attached impurities, realizing the synchronous operation of dust removal and cutting. Step 7: Deep purification and continuous processing of flue gas. After preliminary filtration by the dust filter 6455, the flue gas enters the annular flue pipe 6452 through the smoke extraction pipe 6451. The annular flue pipe 6452 collects the flue gas from each smoke extraction pipe 6451 and then transports it to the purification box 621 of the purification module 62 through the connecting pipe 6453. The purification box 621 performs deep purification treatment on the flue gas. The purified gas is discharged through the suction fan 622. The maintenance window 623 on the top of the purification box 621 facilitates subsequent maintenance and repair. The sealing door 624 ensures the sealing performance of the purification box 621. After cutting, the linear motion module drives the pneumatic clamping fixture and the cut workpiece to leave the cutting area and move it to the unloading station for unloading. At the same time, the next station that has completed loading and clamping is moved to the cutting area for cutting operation by the linear motion module, realizing the alternating cycle processing of multiple stations and completing the continuous and uninterrupted loading, cutting and unloading work. Step 8: Equipment Maintenance and Technical Effects. During long-term use, when the cleaning brush 657 shows wear or needs replacement, the operator unscrews the mounting screw 658 on the mounting rail 655, removes the mounting plate 656 from the mounting rail 655, and replaces or maintains the cleaning brush 657. The mounting screw 658 is designed with a handle, eliminating the need for additional tools. After the purification module 62 has been used for a period of time, the operator unscrews the screws on the sealing door 624, opens the inspection window 623, and cleans and maintains the interior of the purification box 621. Each module is connected by screws or other detachable means, facilitating the assembly, maintenance, and component replacement of this device. This technical solution improves overall work efficiency through the coordinated operation of various structures, multi-station parallel preparation, and alternating cycle design, avoiding waste from waiting at a single station. The transverse movement mechanism 2 and... The precise drive of the lifting electric cylinder 632 ensures the accuracy of cutting positioning and height control. Integrated installation improves the overall stability of the device and reduces the impact of vibration on cutting accuracy. The annularly distributed smoke extraction component 645 achieves all-round collection of smoke, and the dustproof filter 6455 reduces pipe blockage from the source. The synchronous dust removal design realizes automated dust removal, reduces operation and maintenance costs, and ensures production continuity. The purification module 62 effectively removes fine impurities, solves the problem of blockage in the purification system, avoids environmental pollution, and ensures operational safety. The multi-type adaptability of the electrode pneumatic clamp improves the versatility of the device. The mounting screw 658 with a knob and the detachable connection design reduce the difficulty and cost of operation and maintenance. The whole system realizes precise and continuous cutting of the electrode, specifically solves the defects in smoke treatment in the background technology, and is fully adapted to the needs of large-scale precision processing of solid-state battery electrode.

A method for laser cutting solid-state battery tabs, using the solid-state battery tab laser cutting apparatus according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Install the linear moving module in the fixture groove (5) of the cutting workbench (4) through the fixture mounting base (7), install the corresponding type of pole tab pneumatic fixture on the top of the linear moving module, place the pole tab workpiece to be cut on the pole tab pneumatic fixture, fix the pole tab workpiece through the pole tab pneumatic fixture, and form multiple workstations by distributing multiple fixture mounting bases (7) at equal intervals along the fixture groove (5). Complete the loading and clamping of one workstation, and prepare the loading of the other workstations simultaneously. Step 2: Start the linear movement module to move the pneumatic clamp and workpiece along the front-back direction, and move the workpiece to the cutting area directly below the laser cutting head (633). At the same time, start the transverse movement mechanism (2) to drive the cutting mechanism (6) to move along the left and right direction to adjust the cutting position. After the drive motor (221) starts, it drives the synchronous belt (223) through the synchronous wheel (222). The synchronous belt (223) drives the slider (24) to slide along the guide rail (23) through the connecting frame (25), thereby driving the mounting motherboard (61) and the entire cutting mechanism (6) to move synchronously left and right. Step 3: Start the cutting module (63), and drive the laser cutting head (633) to move up and down in the vertical direction through the lifting electric cylinder (632) to adjust the distance between the laser cutting head (633) and the workpiece to a suitable cutting height; Step 4: The laser cutting head (633) emits a laser to cut the tab workpiece, and at the same time, the suction fan (622) in the purification module (62) is started to form a negative pressure inside the dust collection module (64); Step 5: The smoking assembly (645) is aligned with the cutting area through the smoking pipe (6454) to draw in the smoke and impurities generated during cutting.

The purification box (621) performs deep purification treatment on the flue gas. The purified gas is discharged through the suction fan (622). After the cutting is completed, the linear moving module drives the electrode pneumatic clamp and the cut electrode workpiece to leave the cutting area and move to the unloading station for unloading.
