Description

Technical Field

[0001] This utility model relates to the technical field of lead-acid battery production equipment, and in particular to an adaptive cutting and brushing mechanism for the tabs of an integrated device for cutting and brushing the lower groove of the electrode group. Background Technology

[0002] In the manufacturing process of lead-acid batteries, the pre-sinking of electrode groups is a core process. Electrode groups are formed by clamping the electrode plates and AGM separators. After clamping, the electrode groups enter the fixtures of the pre-sinking machine through a designated conveyor channel. The fixtures compress the electrode groups to a specified thickness, and then, via ejector pins, place the electrode groups into the battery casing grooves, completing the sinking operation. In actual production, the clamping process can easily cause positional deviations, misalignment, or uneven arrangement of the electrode tabs. The condition of the tabs directly determines the welding quality of subsequent casting and welding processes. Inconsistent tab heights or the presence of oxides or burrs on the surface will lead to welding defects and reduce battery performance. Therefore, before pre-sinking the electrode groups, the tabs usually need to be trimmed to unify their height and remove surface impurities, ensuring welding reliability.

[0003] Currently, the trimming of electrode tabs mostly employs dedicated cutting and brushing equipment independent of the pre-grooving process, or is done manually using hand tools. Electrode clusters need to be transferred between different equipment or workstations, increasing process time, reducing production efficiency, and repeated handling can easily lead to loosening of the electrode clusters or secondary deformation of the electrode tabs. Furthermore, independent equipment occupies additional workshop space, resulting in high equipment investment and maintenance costs. In addition, existing cutting and brushing mechanisms are mostly rigid, unable to adaptively adjust to the actual condition of the electrode tabs, leading to low trimming accuracy, easy misalignment or damage to the electrode tabs, and even affecting the overall quality of the electrode cluster.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Figures 1 to 5As shown, this utility model discloses an adaptive cutting mechanism for the electrode tabs of an integrated electrode group lower groove cutting and brushing device, including a flipping component 200 and a cutting component 300. The flipping component 200 is disposed on the lower groove device 100 and is provided with a flap 220, which can clamp the clamp 110 of the lower groove device 100 and flip the clamp 110 by 180°. The cutting component 300 is disposed on one side of the flipping component 200. The cutting component 300 is provided with a first support roller 320 and a second support roller 330, which are respectively located on both sides of the clamp 110. A conveyor belt 340 is sleeved on the first support roller 320 and the second support roller 330. Ribs 341 are evenly distributed along the length of the conveyor belt 340, and abrasive cloth 350 is attached between two adjacent ribs 341. The abrasive cloth 350 can abut against the end of the electrode tab of the electrode group in the clamp 110. Specifically, this technical solution uses a flipping component 200 to clamp the fixture 110 and flip it so that the tabs of the electrode group in the fixture 110 face downwards. Simultaneously, the first support roller 320 and the second support roller 330 drive the conveyor belt 340 to rotate, which in turn moves the abrasive cloth 350, which cuts and trims the ends of the tabs. The powder generated during trimming falls downwards due to gravity, away from the electrode group and the fixture 110, preventing powder residue inside the electrode group. Through this structural design, the cutting and brushing component 300 is integrated into the lower trough device 100. This structural design avoids the transfer of the electrode group between different devices, reduces waiting time between processes, avoids the risk of the electrode group becoming loose due to repeated handling, and prevents secondary deformation of the tabs. This technical solution uses a flipping component 200 to clamp the fixture 110 and flip it so that the tabs of the electrode group in the fixture 110 face downwards. Simultaneously, the ends of the electrode tabs are processed by the cutting brush assembly 300, allowing the powder generated during processing to fall off naturally due to gravity, preventing powder from adhering to the electrode tabs or electrode cluster surface and ensuring the cleanliness of the electrode cluster. This technical solution employs a structure where abrasive cloth 350 is attached between adjacent ribs 341. The abrasive cloth 350 can adaptively fit according to the actual height difference and surface morphology of the electrode tab ends. This flexible trimming method avoids the trimming deviation caused by rigid mechanisms, prevents damage to the electrode tabs, and effectively removes oxides and burrs from the electrode tab surface. This structural design improves the overall quality of the electrode cluster while ensuring the welding reliability of subsequent casting and welding processes.

[0025] As a further improvement, the flipping assembly 200 includes a flipping base plate 210, a first bearing seat 230, a second bearing seat 240, a drive shaft 250, and a first motor 260. The first motor 260 is fixedly connected to the flipping base plate 210, and the first bearing seat 230 and the second bearing seat 240 are fixedly connected to both sides of the flipping base plate 210, respectively. One end of the drive shaft 250 is bearing-connected to the first bearing seat 230, and the other end of the drive shaft 250 is bearing-connected to the second bearing seat 240. The end of the drive shaft 250 passes through the first bearing seat 230 and is connected to the output end of the first motor 260 for transmission. The drive shaft 250 is fixedly connected to the flip plate 220. In this embodiment, the first motor 260 outputs power, and the first motor 260 drives the drive shaft 250 to rotate through its output end. The drive shaft 250 drives the flip plate 220 to rotate. The flip plate 220 clamps the clamp 110, and when the flip plate 220 rotates, it drives the clamp 110 to achieve a flipping action. The first bearing seat 230 and the second bearing seat 240 provide rotational support for the drive shaft 250, ensuring its stability during rotation. The first motor 260 is directly connected to the drive shaft 250, resulting in a short transmission chain and fast response. The first bearing seat 230 and the second bearing seat 240 are respectively arranged on both sides of the flip base plate 210, providing two-point support for the drive shaft 250 and reducing vibration and sway during rotation. The flip base plate 210 serves as the mounting base, integrating the first motor 260, bearing seats, and drive shaft 250 into a single unit, facilitating overall fixation on the lower slot device 100. This results in a compact structure and minimal space occupation.

[0026] As a further improvement, the drive shaft 250 is provided with a mounting surface 251 along its axial direction. The drive shaft 250 and the flip plate 220 are connected by bolts through the mounting surface 251. The drive shaft 250 fits against the flip plate 220 through the mounting surface 251, which provides a positioning reference to ensure the accurate relative position of the flip plate 220 and the drive shaft 250. After passing through the flip plate 220, the bolts are screwed into the threaded holes on the mounting surface 251, securing the flip plate 220 to the drive shaft 250. The combination of the mounting surface 251 and the bolts achieves circumferential fixation between the drive shaft 250 and the flip plate 220, ensuring that the flip plate 220 rotates synchronously when the drive shaft 250 rotates, avoiding relative slippage or slippage. This connection method facilitates the installation and disassembly of the flip plate 220, and is beneficial for subsequent maintenance and replacement. The bolt connection structure is simple and reliable, and can meet the positioning accuracy and load-bearing requirements of the flip assembly 200 during repetitive operations.

[0027] As a further improvement, the output end of the first motor 260 is connected to the end of the drive shaft 250 via a flexible coupling 270. Specifically, in this embodiment, the power output by the first motor 260 is transmitted to the drive shaft 250 through the flexible coupling 270. The flexible coupling 270 can absorb the vibration and impact generated during the start-up and operation of the first motor 260. The flexible coupling 270 can compensate for the coaxiality and angular deviations between the output shaft of the first motor 260 and the drive shaft 250. This connection method reduces the rigid impact of the transmission system and improves the smoothness of power transmission. This connection method reduces the wear of the drive shaft 250 and the motor, extending the service life of the equipment.

[0028] As a further improvement, the flip substrate 210 is provided with a clearance groove 211 at the output end of the corresponding clamp 110. In this embodiment, the flip assembly 200 is disposed on the lower slot device 100. The flip assembly 200 is provided with a flip plate 220, which can clamp the clamp 110 of the lower slot device 100 and flip the clamp 110 180°, flipping the clamp 110 from its original working position to the upper end of the brush cutting assembly 300. The brush cutting assembly 300 polishes the tabs of the electrode group in the clamp 110. After the polishing process is completed, the flip assembly resets the clamp 110 and uses other devices to input the tabs in the clamp 110 into the lower conveying mechanism through the clearance groove 211.

[0029] As a further improvement, the cutting brush assembly 300 includes a cutting brush base 310, a second motor 360, a first pulley 361, a second pulley 362, and a synchronous belt 363. The second motor 360 is fixedly connected to the flipping base plate 210, and the output end of the second motor 360 is drivenly connected to the first pulley 361. The second pulley 362 is fixedly connected to the first support roller 320. The two ends of the synchronous belt 363 are respectively sleeved on the first pulley 361 and the second pulley 362. The first support roller 320 is rotatably connected to the cutting brush base 310. The second motor 360 drives the first pulley 361 to rotate through its output end. The first pulley 361 transmits power to the second pulley 362 through the synchronous belt 363. The second pulley 362 drives the first support roller 320 to rotate. The first support roller 320 drives the conveyor belt 340 to move. The cutting brush base 310 provides rotational support for the first support roller 320. In this structure, the second motor 360 is fixed to the flipping base plate 210, integrating the drive part of the cutting brush assembly 300 with the flipping assembly 200 on the same mounting base. This results in a compact structure and reduces the need for additional support components. The synchronous belt 363 transmission method can absorb vibrations during motor startup and operation, ensuring smooth motion transmission. The transmission mechanism composed of the first pulley 361, the second pulley 362, and the synchronous belt 363 occupies little space and is easy to arrange on one side of the cutting brush base 310. This transmission method requires no lubrication, is easy to maintain, operates with low noise, and is suitable for workshop environments.

[0030] As a further improvement, the two ends of the first support roller 320 are rotatably connected to the cutter base 310 via a bearing 321. This design provides stable power output.

[0031] As a further improvement, the brush base 310 is provided with support arms 370 and limiting bolts 372 on both sides. The lower end of the support arm 370 is fixedly connected to the flip base plate 210. A limiting hole 371 is provided vertically on the support arm 370. Mounting holes are provided on both sides of the brush base 310 corresponding to the limiting hole 371. One end of the limiting bolt 372 passes through the limiting hole 371 and is threaded into the mounting hole. The lower end of the support arm 370 is fixed to the flip base plate 210, providing support and a mounting base for the brush base 310. The limiting hole 371 is vertically oriented. The brush base 310 is connected to the mounting hole after the limiting bolt 372 passes through the limiting hole 371, achieving relative fixation between the brush base 310 and the support arm 370. When the height of the brush base 310 needs to be adjusted, the limiting bolt 372 is loosened, and the brush base 310 moves vertically up and down along the limiting hole 371. After the brush is moved into place, tighten the limiting bolt 372 to lock the position of the brush base 310. The limiting hole 371 extends vertically, providing guidance and travel limitation for the height adjustment of the brush base 310, ensuring that the brush base 310 does not tilt during vertical movement. The limiting bolt 372 serves both as a connector and a lock, with a simple structure and convenient operation, requiring no additional locking components. The height of the brush base 310 is adjustable, allowing the abrasive cloth 350 to be adaptively adjusted according to different specifications of electrode groups and the initial height of the electrode tabs, ensuring that the abrasive cloth 350 can accurately abut against the end of the electrode tab for processing. This adjustment structure improves the versatility and processing accuracy of the brush assembly 300.

[0032] As a further improvement, the cutting brush base 310 is provided with adjustment grooves 311 on both sides. The two ends of the second support roller 330 are slidably disposed in the adjustment grooves 311. The cutting brush assembly 300 also includes a tensioning block 381, a tensioning screw 382, ​​and a fisheye bearing 383. The tensioning block 381 is fixedly connected to the cutting brush base 310, and the tensioning screw 382 is threadedly connected to the tensioning block 381. One end of the tensioning screw 382 passes through the tensioning block 381 and is rotatably connected to the fisheye bearing 383. One end of the fisheye bearing 383 is rotatably connected to the end of the second support roller 330. When the tensioning screw 382 is rotated, it moves axially relative to the tensioning block 381. The tensioning screw 382 drives the fisheye bearing 383 to move. The fisheye bearing 383 drives the end of the second support roller 330 to slide along the adjustment grooves 311. The adjusting groove 311 restricts the movement direction of the second support roller 330, causing it to move along the extension direction of the adjusting groove 311. As the second support roller 330 moves, the center distance between it and the first support roller 320 changes. The conveyor belt 340 is thus tensioned or relaxed. Once the desired tension is reached, the tension screw 382 stops rotating and maintains its current position via thread self-locking. The adjusting groove 311 provides a sliding guide for the second support roller 330, ensuring synchronous movement at both ends. The threaded engagement of the tension screw 382 and the tension block 381 provides precise displacement control, allowing the operator to adjust the tension as needed. A fisheye bearing 383 connects the ends of the tension screw 382 and the second support roller 330, compensating for angular deviations between them and preventing bending forces on the screw. This tensioning structure maintains proper tension on the conveyor belt 340, preventing slippage. When the conveyor belt 340 becomes loose after long-term use, this structure allows for convenient compensation and adjustment, ensuring the stability of the conveyor belt 340's operation.

[0033] As a further improvement, a locking nut 384 is provided at one end of the tensioning screw 382. After the tensioning screw 382 completes the tension adjustment of the conveyor belt 340, the locking nut 384 is tightened. The locking nut 384 moves towards the tensioning block 381. The end face of the locking nut 384 abuts against the side of the tensioning block 381. The locking nut 384 generates friction in the abutting state, which prevents the tensioning screw 382 from rotating relative to the tensioning block 381. This locking structure can prevent the tensioning screw 382 from loosening due to vibration during equipment operation. This locking structure can keep the position of the second support roller 330 constant, ensure the long-term stability of the tension of the conveyor belt 340, reduce the frequency of equipment adjustment, and improve the reliability of operation.

[0034] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
