Description

Technical Field

[0001] This utility model relates to the technical field of battery tab shaping equipment, specifically, to a lithium battery tab shaping device. Background Technology

[0002] In the field of lithium battery manufacturing, the tabs are key components that connect the internal and external circuits of the battery. Their shape, size and conductivity have a crucial impact on the overall performance of the battery. The tabs are usually made of metal sheets (such as copper or nickel) and are connected to the positive and negative current collectors of the battery by welding or mechanical connection, so as to conduct electricity and transmit current.

[0003] Traditional lithium battery tab shaping processes primarily employ stamping. During stamping, the closing of upper and lower dies presses out the desired shape, achieving the desired shaping effect. However, this type of stamping operation can only press a single metal sheet at a time, and after pressing, it needs to be removed from the mold for unloading. Although some molds are equipped with ejection mechanisms to remove the tabs, the unloading process still requires manual intervention, which is relatively cumbersome and affects processing efficiency. Therefore, we propose a lithium battery tab shaping device. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a shaping device for lithium battery tabs, including a support plate 1. A shaping mold 11 and a cutting mold 13 are detachably installed on the left and right sides of the support plate 1, respectively. Specifically, a first rectangular groove 10 and a second rectangular groove 12 are respectively provided on the left and right sides of the support plate 1. The shaping mold 11 is fixedly installed on the bottom wall of the first rectangular groove 10 by multiple fastening screws, and the cutting mold 13 is fixedly installed on the bottom wall of the second rectangular groove 12 by multiple fastening screws, so as to facilitate the fixing, installation and disassembly replacement operations.

[0027] Specifically, support frames 14 are fixedly installed on both the left and right sides of the support plate 1. A first cylinder 16 is fixedly installed on the top plate of the support frame 14 located on the front side. A fixed plate 161 is fixedly installed at the end of the telescopic shaft of the first cylinder 16. A shaping moving mold 162 is fixedly installed on the bottom surface of the fixed plate 161. The shaping moving mold 162 is located directly above the shaping fixed mold 11. As the shaping moving mold 162 moves downward, the metal strip between the shaping fixed mold 11 and the shaping moving mold 162 is shaped.

[0028] Specifically, a second cylinder 17 is fixedly installed on the top plate of another support frame 14. A movable template 171 is fixedly installed at the end of the telescopic shaft of the second cylinder 17. A cutting movable mold 172 is fixedly installed on the bottom surface of the movable template 171. The cutting movable mold 172 is located directly above the cutting fixed mold 13. When the shaped electrode tab on the metal strip moves between the cutting movable mold 172 and the cutting fixed mold 13, a cutting operation can be performed to separate the shaped electrode tab from the metal strip.

[0029] In this embodiment, a rectangular hole 121 communicating with the outside is provided on the bottom wall of the second rectangular groove 12, and a material discharge hole 131 is provided on the cutting mold 13. The material discharge hole 131 is used for the electrode tabs that have been shaped and cut off from the metal strip to fall down for unloading.

[0030] Specifically, multiple support legs 15 arranged in a matrix are fixedly installed at the bottom of the support plate 1. The height of the support legs 15 is greater than 60cm, so that the support legs 15 can be used for support operation.

[0031] Furthermore, two symmetrical guide sleeves 18 are fixedly installed on the top surfaces of both the moving template 171 and the fixed plate 161. Guide posts 19 are slidably connected inside the guide sleeves 18. The guide posts 19 are fixedly installed on the corresponding support frame 14, which serves to guide the moving template 171 and the fixed plate 161.

[0032] In addition, the size of the rectangular hole 121 is larger than the size of the blanking hole 131, and the size of the cutting moving die 172 is adapted to the size of the blanking hole 131 for normal cutting and blanking operations.

[0033] It is worth noting that two symmetrical side plates 2 are fixedly installed on the side of the support plate 1. The two side plates 2 are rotatably connected by two symmetrical upper and lower conveying rollers 21 through a rotating shaft 20. A drive motor 23 is coaxially installed at the end of one of the rotating shafts 20. Gears 22 are fixedly installed at the same end of both rotating shafts 20, and the upper and lower gears 22 mesh with each other. The conveying rollers 21 are located on one side of the support frame 14 and are parallel to the support frame 14. The conveying rollers 21 are located on the side of the forming moving mold 162 away from the cutting moving mold 172. The rotation of the upper and lower conveying rollers 21 enables the long strip of thin metal sheet to be conveyed to the forming fixed mold 11 and the cutting fixed mold 13 for processing.

[0034] When using the lithium battery tab shaping device of this utility model, a long strip of thin metal sheet is placed between two upper and lower conveying rollers 21. The drive motor 23 is connected to an external power source and made to work. When the drive motor 23 works, its output shaft rotates, which drives the conveying rollers 21 to rotate. The rotation of the conveying rollers 21 realizes the forward conveying of the strip of thin metal sheet.

[0035] After the strip metal sheet is conveyed to the shaping mold 11, the first cylinder 16 is activated and put into operation. When the first cylinder 16 is in operation, its telescopic shaft extends and drives the shaping moving mold 162 to move downward, thereby realizing the shaping operation of the metal strip between the shaping mold 11 and the shaping moving mold 162. After the shaping is completed, the telescopic shaft of the first cylinder 16 shortens and drives the shaping moving mold 162 to move upward. At this time, as the conveying roller 21 continues to rotate, the strip metal sheet can continue to be conveyed forward. At this time, the telescopic shaft of the first cylinder 16 continues to extend, so that the shaping operation can continue to be performed on other parts of the strip metal sheet.

[0036] When the shaped tab on the strip metal sheet moves to the cutting mold 13, the second cylinder 17 is activated and put into operation. When the second cylinder 17 is in operation, the telescopic shaft on it extends and drives the cutting moving mold 172 to move downward, so as to cut the shaped tab at the cutting mold 13. The cut tab can fall out from the dropping hole 131 and the rectangular hole 121 to complete the unloading.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
