Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and in particular relates to a battery tab bending device. Background Art

[0002] During battery manufacturing, plates are a crucial component. With advancements in battery production technology, parallel connection of plates is now common practice in current manufacturing processes to increase battery capacity and achieve a more compact structure. Plates of the same polarity are connected together to form an assembly called a plate group. Plate groups are made by alternately separating positive and negative plates with separator paper. Currently, plate groups are typically produced using a plate-wrapping machine or manually. After this process is complete, the plate assembly needs to be placed in a shell and welded. To facilitate welding of the tabs, the tabs are often bent.

[0003] The existing Chinese utility model with publication number CN202121753964.5 discloses a tab bending device for a battery pole group, which relates to the technical field of battery pole group production. The utility model includes a workbench, a first pressing plate, a first fixing block, a second pressing plate and a bending plate. In response to the problems of manual operation of the existing tab bending process, low work efficiency, inability to ensure consistency in the tab bending angle, and high defective rate, the utility model provides a first pressing plate and a second pressing plate to firmly clamp the pole group to prevent deviation, and then fix the bending plate to the first rotating shaft through a first connecting rod, and the servo motor is fixedly connected to the first rotating shaft; the servo motor controls the rotation angle of the first rotating shaft, thereby accurately controlling the bending angle of the bending plate to the tab, effectively ensuring the consistency of the tab bending angle, and improving production efficiency and product quality.

[0004] Although the above-mentioned battery pole group and tab bending device can accurately control the bending angle of the bending plate to the tab, workers are required to manually place the pole group to the processing position before using the device for processing. After the processing is completed, the processed pole group also needs to be taken out for the next processing. This results in each device requiring a worker to perform the placement and removal operations to cooperate with the normal operation of the device, resulting in low processing efficiency and not suitable for the processing of large quantities of pole groups.

[0037] Example 1

[0038] See also Figures 1-4As shown, the present invention is a battery tab bending device, comprising a base 1 and a processing platform 2.

The base 1 is provided with a rotating chassis 101, and the top surface of the rotating chassis 101 is provided with a rotating groove 102. The bottom surface of the processing platform 2 is provided with a rotating block 201. The rotating block 201 is rotatably mounted in the rotating groove 102.

Eight groups of first mounting brackets 4 are fixedly mounted on the top of the rotating chassis 101. The eight groups of first mounting brackets 4 are evenly arranged in a circular shape on the rotating chassis 101. Each first mounting bracket 4 is rotatably mounted with a roller 5. The roller 5 is in rolling connection with the lower surface of the processing platform 2.

[0039] Also, see Figures 1-4 As shown, a rotating mechanism is provided between the processing platform 2 and the base 1 for driving the processing platform 2 to rotate above the base 1, so that the processing platform 2 can rotate and stop according to actual needs; the rotating mechanism includes a driving motor 6 and a rotating gear 7, and four groups of mounting blocks 103 are evenly provided on the circumferential side of the rotating chassis 101. The bottom surface of each mounting block 103 is fixedly mounted with a driving motor 6, and the rotating shaft of the driving motor 6 passes through the mounting block 103, and the rotating shaft of the driving motor 6 is fixedly connected to the rotating gear 7. The driving motor 6 can drive the driving gear forest 7 to rotate synchronously, and a gear ring 202 is provided on the ground of the processing platform 2, and the gears of the gear ring 202 are opened on the inner side. The four groups of rotating gears 7 are all engaged with the gear ring 202, which can realize horizontal rotation of the processing platform 2 when the driving motor 6 is working, and stop rotation of the processing platform 2 when the driving motor 6 stops working. By setting the start and stop interval of the driving motor 6 in advance, the rotation angle of the processing platform 2 can be controlled.

[0040] See also Figures 1-8As shown, four groups of processing boxes 3 for placing battery pole groups are fixedly installed on the circumferential side of the top surface of the processing platform 2. Different numbers of groups can be set according to actual needs. The top of each processing box 3 is provided with a bending mechanism for completing the tab bending work; both sides of each processing box 3 are provided with fixing mechanisms for positioning and fixing the battery pole groups. The fixing mechanism includes a pneumatic telescopic rod 8 and a fixing plate 10. The pneumatic telescopic rod 8 includes a piston part 801 and a main body part 802.

During processing, the pole group that needs to be bent is placed into the processing box 3, and the pneumatic telescopic rods 8 on both sides of the processing box 3 are started to make the piston part 801 pass through the through holes 301 to clamp the pole group that needs to be bent, and the pole group is bent by the bending mechanism arranged on the top of the processing box 3; the fixing plate 10 includes a sliding part 1001 and a limiting part 1002. Slide grooves 302 are provided on both sides of the processing box 3. The sliding part 1001 is slidably connected to the slide groove 302, and a sliding hole 1003 is provided on the limiting part 1002. The piston part 801 is slidably connected to the sliding hole 1003, and two groups of first limit posts 11 are respectively provided on both sides of the processing box body 3. The first limit posts 11 pass through the limit part 1002, and the first limit posts 11 are slidably connected to the limit part 1002, which realizes the sliding displacement of the fixed plate 10 in the extension direction of the pneumatic telescopic rod 8, and a spring 12 is sleeved on the piston part 801, one end of the spring 12 abuts against the limit part 1002, and the other end of the spring 12 abuts against the main body 802, which realizes that during the extension process of the piston part 801 of the pneumatic telescopic rod 8, under the expansion action of the spring 12, the fixed plate 10 moves along the extension direction of the piston part 801 until the two groups of fixed plates 10 are closed, and the piston part 801 of the pneumatic telescopic rod 8 continues to extend and fit the pole group that needs to be bent. In this way, the position of the pole group is fixed and the position of the pole group can be prevented from changing during the rotation of the processing platform 2.

[0041] In the actual processing process, a worker places the pole group to be processed into the processing box 3, starts the pneumatic telescopic rod 8, closes the fixed plate 10 and clamps the pole group plate with the two piston parts, then starts the drive motor 6 to rotate the processing platform 2, and places another pole group to be processed into the next processing box 3. At the same time, another worker is arranged on the other side of the processing platform 2 to take out the processed pole group to complete the cycle. In this way, two people can continuously process the pole groups that need to be bent, thereby improving processing efficiency.

In addition, two conveyor lines 16 are provided around the processing platform 2, one for transporting the electrode groups to be processed to the processing platform and the other for transporting the completed electrode groups to the next processing step. This saves workers time in transporting the electrode groups and further improves processing efficiency. The pushing mechanism includes a pushing plate 13 and a pushing cylinder 14. The pushing plate 13 is arranged on the inner side wall of the processing box 3 near the center of the processing platform 2.

The four groups of second limiting columns 1301 pass through the side wall of the processing box 3 near the center of the processing platform 2, and the second limiting columns 1301 are slidably connected to the processing box 3. A mounting frame 15 is provided on the side of the processing box 3 near the center of the processing platform 2. The pushing cylinder 14 is fixedly installed on the mounting frame 15 by bolts. The piston end of the pushing cylinder 14 passes through the processing box 3 and is fixedly connected to the pushing plate 13. By driving the pushing cylinder 14, it is possible to limit the pole group to be processed when it is placed in the processing box 3, and the pole group that has been processed can be pushed out of the processing box 3 after the processing is completed, thereby improving the processing efficiency.
