Technical Field

[0001] This utility model relates to the field of battery tab shaping technology, specifically a battery tab installation and shaping device. Background Technology

[0002] During the battery manufacturing process, the tabs of different batteries need to be welded together. The tabs are long strips, and when the tabs are assembled onto the battery, the length direction of the tabs is perpendicular to the axial direction of the battery, such as a lithium battery. Therefore, the tabs need to be bent before welding so that the tabs of different batteries can be brought closer to each other to facilitate welding. Generally, the above-mentioned bending of the tabs is called tab shaping.

[0003] Before laser welding, the tabs need to be flattened against the PCB. Currently, this is done manually using auxiliary tools to shape the tabs. Shaping a single tab takes a considerable amount of time and cannot guarantee consistency across all products, potentially leading to poor laser welding.

[0004] Now, a novel battery tab mounting and shaping device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to automate the tab shaping and bending process. This involves pre-bending, vertical rolling, and then horizontal rolling, using multiple rolling methods to ensure the tab adheres to the PCBA, guaranteeing consistency and yield during laser welding. The shaping fixture uses pressure sensors and springs to ensure that the stress between the tab and the PCBA does not exceed the limit.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery tab mounting and shaping device, comprising a mounting base, wherein an automatically shaping movable component is provided on the left side of the front end of the mounting base.

A second bearing groove is provided at the top of the second mounting plate. A second T-shaped module is fixedly connected to the front end of the second mounting plate. Second bushings are provided at the four corners of the top of the second T-shaped module. Second springs are provided at the four corners of the bottom of the second T-shaped module. A second fixing frame is fixedly connected to the bottom of the second spring. A bending blade is fixedly connected to the four corners of the bottom of the second fixing frame. A pressure sensor is provided inside the bending blade.

[0008] As a further technical solution of this utility model, the positions of multiple sets of the first bushings and the first springs correspond one-to-one, and the first T-shaped module and the second mounting plate are made of the same material.

[0009] As a further technical solution of this utility model, the external shape and size of the first cylinder output end are adapted to the internal shape and size of the first bearing groove, and the external shape and size of the second cylinder output end are adapted to the internal shape and size of the second bearing groove.

[0010] As a further technical solution of this utility model, the positions of the second bushing and the second spring correspond one-to-one, and the vertical center lines of the second bushing and the second fixing frame coincide.

[0014] As a further technical solution of this utility model, the connecting plate and the mounting base are fixedly connected, the shape and size of the inside of the slide block are adapted to the shape and size of the outside of the slide plate, and the slide plate can move up and down along the inside of the slide block.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the battery tab installation and shaping device not only realizes the function of automatic bending and rolling, but also realizes the function of all-round processing and flexible installation.

The first cylinder and the second cylinder are respectively installed on the left and right sides of the front end of the mounting base. The output end of the second cylinder engages with the second bearing groove, so that the second mounting plate can be moved up and down by the drive of the second cylinder, thereby driving the second T-shaped module to move towards the battery tab below it, and the bending cutter bends the battery tab.

The processed battery tabs maintain a high degree of consistency and realize the function of automatic bending and flattening.

[0017] (2) By setting a third support, a third spring, a third fixed frame, and a vertical pulley, the battery tab is sent to the bottom of the horizontal roller for horizontal rolling after being bent by the bending knife. During this process, it passes under the third fixed frame fixed by the third support until it contacts the vertical pulley inside the third fixed frame. Then, under the squeezing action of the vertical pulley, the surface of the battery tab after bending is vertically rolled flat. The third spring at the top of the third fixed frame can buffer the pressure of the vertical pulley to prevent processing deformation. The rolling effect of the battery tab is more comprehensive, realizing the all-round processing function.

At the same time, the movable plate slides up and down on the left and right sides of the slide via the sliding plate, so that the position of the movable plate can be changed.

[0029] Please see Figure 1-7 A battery tab mounting and shaping device further includes a movable component, which includes a first cylinder 2, located on the left side of the front end of the mounting base 1.

A bending blade 17 is fixedly connected to the four corners of the bottom end of the second fixing frame 16. A pressure sensor 27 is provided inside the bending blade 17.

[0030] The positions of multiple sets of first bushings 6 and first springs 7 correspond one-to-one. The first T-shaped module 5 and the second mounting plate 12 are made of the same material. The external shape and size of the output end of the first cylinder 2 are adapted to the internal shape and size of the first bearing groove 3.

After being bent, the battery tabs come to the bottom of the first fixed frame 8, and then the output end of the first cylinder 2 engages with the first bearing groove 3, causing the first mounting plate 4 to move up and down under the drive of the first cylinder 2. At the same time, it drives the first T-shaped module 5 to move downward until the transverse roller 9 inside the first fixed frame 8 contacts the surface of the battery tabs and flattens them. The first spring 7 at the top of the first fixed frame 8 is fixed by the first bushing 6. When the transverse roller 9 flattens the surface of the bent battery tabs, the first spring 7 can buffer the driving pressure of the first cylinder 2 to prevent excessive stress from causing deformation of the processed surface. This not only improves the forming efficiency but also reduces the processing time, and the processed battery tabs maintain a high degree of consistency.

[0032] A third bearing seat 18 is fixedly connected to the middle position of the front end of the mounting base 1.

A third fixing frame 20 is fixedly connected to the bottom end of the third spring 19. A vertical pulley 21 is provided inside the third fixing frame 20. The vertical center lines of the third fixing frame 20 and the vertical pulley 21 coincide. There is a distance between the vertical pulley 21 and the horizontal roller 9 and the bending knife 17.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 7 As shown, after being bent by the bending knife 17, the battery tab is sent to the bottom of the horizontal roller 9 for horizontal flattening. During this process, it passes under the third fixed frame 20 fixed by the third support seat 18 until it contacts the vertical pulley 21 inside the third fixed frame 20. Under the squeezing action of the vertical pulley 21, the surface of the battery tab after bending is vertically flattened. The third spring 19 at the top of the third fixed frame 20 can buffer the pressure of the vertical pulley 21 to prevent processing deformation, and the flattening effect of the battery tab is more comprehensive.

[0034] A connecting plate 22 is provided above the third support seat 18. A slide 23 is fixedly connected to the front end of the connecting plate 22. A slide plate 25 is movably connected to the outside of the slide 23. A movable plate 24 is fixedly connected to the front end of the slide plate 25.

The shape and size inside the slide 23 are adapted to the shape and size outside the slide plate 25. The slide plate 25 can move up and down along the inside of the slide 23.

[0035] Specifically, such as Figure 1 , Figure 6 and Figure 7 As shown, a connecting plate 22 is fixedly connected to the upper part of the front end of the mounting base 1, and a slide 23 is installed in front of the connecting plate 22. At the same time, the moving plate 24 slides up and down on the left and right sides of the slide 23 via the sliding plate 25, so that the position of the moving plate 24 can be changed. By inserting the mounting component that docks with the shaping device into the mounting hole 26 inside the moving plate 24, it is convenient to install the whole device according to different processing areas, and the applicability of the shaping device installation and use is better.

[0036] Working principle: In use, the first cylinder 2 and the second cylinder 10 are first installed on the left and right sides of the front end of the mounting base 1, respectively. The output end of the second cylinder 10 engages with the second bearing groove 11, allowing the second mounting plate 12 to move up and down under the drive of the second cylinder 10. This causes the second T-shaped module 13 to move towards the battery tab below it, and the bending blade 17 bends the battery tab. The bending blade 17 is equipped with a pressure sensor 27, and a second spring 15 is installed above the bending blade 17 via a second bushing 14. When the bending blade 17 bends the battery tab... During processing, the second spring 15 can provide cushioning, and the pressure sensor 27 monitors the driving pressure of the second cylinder 10 to prevent excessive stress. After bending, the battery tabs come to the bottom of the first fixing frame 8, and then the output end of the first cylinder 2 engages with the first bearing groove 3, causing the first mounting plate 4 to move up and down under the drive of the first cylinder 2, while simultaneously driving the first T-shaped module 5 to move downwards until the transverse roller 9 inside the first fixing frame 8 contacts the surface of the battery tabs and flattens them. The first spring 7 at the top of the first fixing frame 8 is fixed by the first bushing 6. When the transverse roller 9 flattens the bent battery... When the surface of the battery tab is rolled, the driving pressure of the first cylinder 2 is buffered by the first spring 7 to prevent excessive stress from causing deformation of the processed surface. This not only improves the forming efficiency but also reduces the processing time. The processed battery tabs maintain a high degree of consistency. After being bent by the bending cutter 17, the battery tabs are sent to the bottom of the transverse roller 9 for transverse rolling. During this process, they pass under the third fixed frame 20, which is fixed by the third support seat 18, until they contact the vertical pulley 21 inside the third fixed frame 20. Then, under the squeezing action of the vertical pulley 21, the bent surface of the battery tab is vertically rolled flat. The third spring 19 at the top of the third fixed frame 20 can buffer the pressure of the vertical pulley 21 to prevent processing deformation, and the rolling effect of the battery tabs is more comprehensive. A connecting plate 22 is fixedly connected to the upper front end of the mounting base 1, and a slide 23 is installed in front of the connecting plate 22. At the same time, the moving plate 24 slides up and down on the left and right sides of the slide 23 through the sliding plate 25, so that the position of the moving plate 24 can be changed. By connecting the mounting parts that dock with the shaping device into the mounting holes 26 inside the moving plate 24, it is convenient to install the whole device according to different processing areas, and the applicability of the shaping device installation and use is better.
