Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a cell tab bending mechanism and a cell welding and coating integrated equipment. Background Technology

[0002] In the lithium battery manufacturing process, the battery electrodes require current collector welding and circumferential encapsulation. The former connects the electrodes of the entire cell to form a unified conductive system, while the latter ensures the insulation of the electrodes inside the battery, preventing contact with the steel casing. Both processes are indispensable parts of lithium battery production. Before welding the current collectors, the tabs of the positive current collector extend radially relative to the battery. These tabs need to be bent to ensure their position does not obstruct the subsequent encapsulation process.

[0003] Currently, the equipment for bending the tabs is arranged separately, requiring manual placement of each cell in sequence, which makes continuous processing impossible and results in poor production efficiency. Utility Model Content

[0034] Please see Figures 1 to 5 One embodiment of this utility model provides a battery cell tab bending mechanism, including: a battery cell support assembly 10, a battery cell rotation assembly 20, and multiple tab bending assemblies 30.

[0035] The cell support assembly 10 includes a first cell lifting seat 11, a second cell lifting seat 12, and a cell lifting module 13. A clearance conveying space 14 is formed between the first cell lifting seat 11 and the second cell lifting seat 12, through which the cell conveying mechanism passes. Multiple support wheels 111 are rotatably arranged on both the first cell lifting seat 11 and the second cell lifting seat 12. The multiple support wheels 111 are arranged sequentially along the extension direction of the clearance conveying space 14. A support space 112 is formed between two adjacent support wheels 111 on the first cell lifting seat 11 and between two adjacent support wheels 111 on the second cell lifting seat 12.

[0036] The cell rotation assembly 20 includes a mounting base 21, a wheel drive module 22, and multiple drive wheels 23. The wheel drive module 22 is drivenly connected to the multiple drive wheels 23. The drive wheels 23 are arranged above the clearance conveying space 14, and the multiple drive wheels 23 are arranged sequentially along the extension direction of the clearance conveying space 14.

[0037] Multiple tab bending assemblies 30 are arranged on one side of multiple support spaces 112. Each tab bending assembly 30 includes a tab detection module 31, a first tab bending member 32, and a first bending drive module 33. The tab detection module 31 is arranged on one side of the support space 112 of the first cell lifting seat 11. The first bending drive module 33 is drivenly connected to the first tab bending member 32. The first tab bending member 32 is arranged on one side of the support space 112 of the first cell lifting seat 11. The first tab bending member 32 moves back and forth from the first cell lifting seat 11 to the second cell lifting seat 12 under the drive of the first bending drive module 33.

[0038] Please see Figure 6 The working principle of the battery cell tab bending mechanism according to one embodiment of this utility model is explained below:

[0039] The cell conveying mechanism passes through the clearance conveying space 14. The subcontracted cell 40 is conveyed horizontally by the cell conveying mechanism between the first cell lifting seat 11 and the second cell lifting seat 12. The positive terminal of the subcontracted cell 40 faces the first cell lifting seat 11, and both ends of the subcontracted cell 40 extend from both sides of the cell conveying mechanism. The cell lifting module 13 drives the first cell lifting seat 11 and the second cell lifting seat 12 to rise. The parts of the subcontracted cell 40 extending from both sides of the cell conveying mechanism will enter the support space 112. The two support wheels 111 on the first cell lifting seat 11 and the two support wheels 111 on the second cell lifting seat 12 jointly support one subcontracted cell 40. The first cell lifting seat 11 and the second cell lifting seat 12 rise until the top of the subcontracted cell 40 abuts against the bottom of the power wheel 23. At this time, the power wheel 23 contacts the subcontracted cell 40. The rear-wheel drive module 22 drives the power wheel 23 to rotate. The friction between the power wheel 23 and the processed battery cell 40 will drive the processed battery cell 40 to rotate. Since the support wheel 111 can rotate, the friction between the support wheel 111 and the processed battery cell 40 is rolling friction, so the processed battery cell 40 can rotate relatively smoothly. After the processed battery cell 40 rotates to a specific position, the tab of the current collector of the positive terminal of the processed battery cell 40 will trigger the tab detection module 31. After the tab detection module 31 detects the tab, the first tab bending member 32 moves under the drive of the first bending drive module 33. Since the tab is a radial extension relative to the processed battery cell 40, the tab protrudes from the processed battery cell 40. The first tab bending member 32 moves along the axial direction of the processed battery cell 40. As the first tab bending member 32 moves, it will drive the tab to bend axially toward the processed battery cell 40, so that the tab extends axially.

[0040] The specific structure of the cell lifting module 13 can be designed according to actual needs. For example, the cell lifting module 13 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example.

[0041] The specific structure of the first bending drive module 33 can be designed according to actual needs. For example, the first bending drive module 33 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example.

[0042] The specific structure of the wheel drive module 22 can be designed according to actual needs. For example, the wheel drive module 22 includes multiple wheel drive motors, which are connected to the drive wheels 23.

[0043] In some optional embodiments, the cell support assembly 10 further includes a first cell positioning seat 15, a second cell positioning seat 16, a first positioning drive module 17, and a second positioning drive module 18. The first cell positioning seat 15 is movably disposed on the first cell lifting seat 11 and is located on the side of the first cell lifting seat 11 away from the second cell lifting seat 12. The first positioning drive module 17 is drivenly connected to the first cell positioning seat 15. Under the drive of the first positioning drive module 17, the first cell positioning seat 15 approaches and moves away from the support wheel 111 of the first cell lifting seat 11. The second cell positioning seat 16 is movably disposed on the second cell lifting seat 12 and is located on the side of the second cell lifting seat 12 away from the first cell lifting seat 11. The second positioning drive module 18 is drivenly connected to the second cell positioning seat 16. Under the drive of the second positioning drive module 18, the second cell positioning seat 16 approaches and moves away from the support wheel 111 of the second cell lifting seat 12. After the cell lifting module 13 drives the first cell lifting seat 11 and the second cell lifting seat 12 to rise, the support wheel 111 supports the processed cell 40. Then, the first cell positioning seat 15 and the second cell positioning seat 16 move toward the support wheel 111. The first cell positioning seat 15 abuts against the positive terminal of the processed cell 40, so that the current collector on the positive terminal of the processed cell 40 is pressed. The second cell positioning seat 16 abuts against the negative terminal of the processed cell 40. The support wheel 111 supports the processed cell 40, and the first cell positioning seat 15 and the second cell positioning seat 16 cooperate to restrict the two sides of the processed cell 40. Then, the power wheel 23 presses the processed cell 40 downward, so that the processed cell 40 is restricted vertically and laterally, improving the stability of the restriction.

[0044] The specific structure of the first positioning drive module 17 and the second positioning drive module 18 can be designed according to actual needs. For example, the first positioning drive module 17 and the second positioning drive module 18 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and are not limited to this example.

[0045] In some optional embodiments, a plurality of first positioning elements 151 are provided on the first cell positioning seat 15, and the plurality of first positioning elements 151 are correspondingly arranged on one side of the support space 112. A plurality of second positioning elements 161 are rotatably provided on the second cell positioning seat 16, and the plurality of second positioning elements 161 are correspondingly arranged on one side of the support space 112. When the first cell positioning seat 15 moves toward the support wheel 111, the first positioning elements 151 abut against the positive terminal of the processed cell 40 in the support space 112. When the second cell positioning seat 16 moves toward the support wheel 111, the second positioning elements 161 abut against the negative terminal of the processed cell 40 in the support space 112. The first positioning elements 151 abut against the positive terminal of the processed cell 40, and the second positioning elements 161 abut against the negative terminal of the processed cell 40. The friction between the second positioning elements 161 and the processed cell 40 causes the second positioning elements 161 to rotate with the processed cell 40, thereby facilitating the positional stability of the processed cell 40.

[0046] In some optional embodiments, the tab bending assembly 30 further includes a second tab bending member 34 and a second bending drive module 35. The second tab bending member 34 is vertically and vertically disposed above the first cell positioning seat 15. The second bending drive module 35 is drivenly connected to the second tab bending member 34. After the first tab bending member 32 moves, it will drive the tab to bend axially toward the processed cell 40. Then the second tab bending member 34 will descend to press the tab onto the first cell positioning seat 15, so that the tab is stably straightened.

[0047] The specific structure of the second bending drive module 35 can be designed according to actual needs. For example, the second bending drive module 35 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc., and is not limited to this example.

[0048] Please see Figures 7 to 8 In some optional embodiments, the second electrode bending member 34 is positioned above the first positioning member 151. The first positioning member 151 has a support portion 152. After the second electrode bending member 34 descends, it can drive the electrode to press against the support portion 152. When the electrode is bent by the first electrode bending member 32, it also bends towards the support portion 152. Since the second electrode bending member 34 cannot completely straighten the electrode, it descends under the drive of the second bending drive module 35, pressing the electrode against the support portion 152, thus stably straightening the electrode. In this embodiment, the moving direction of the first electrode bending member 32 and the moving direction of the second electrode bending member 34 are perpendicular to each other.

[0049] In some optional embodiments, both the first cell lifting seat 11 and the second cell lifting seat 12 are provided with movable tracks 113. The first cell positioning seat 15 is slidably connected to the movable track 113 of the first cell lifting seat 11, and the second cell positioning seat 16 is slidably connected to the movable track 113 of the second cell lifting seat 12. The first cell lifting seat 11 and the second cell lifting seat 12 are moved stably through the movable tracks 113.

[0050] In some alternative embodiments, a friction layer 24 is provided on the outer peripheral surface of the drive wheel 23. The friction layer 24 can be a rubber layer or a silicone layer, etc. The friction layer 24 can increase the friction between the drive wheel 23 and the processed battery cell 40, thereby ensuring that the drive wheel 23 can drive the processed battery cell 40 to rotate, so that the processed battery cell 40 can rotate to a suitable angle.

[0051] In some optional embodiments, the first cell lifting seat 11 and the second cell lifting seat 12 are connected to each other by a connector 19, and the cell lifting module 13 is driven to the first cell lifting seat 11 or the second cell lifting seat 12, so that the cell lifting module 13 can be arranged on one side of the conveying space 14 to facilitate the simultaneous lifting of the first cell lifting seat 11 and the second cell lifting seat 12 by the cell lifting module 13.

[0052] The aforementioned battery cell tab bending mechanism can be applied to a battery cell welding and coating integrated equipment, which includes: the aforementioned battery cell tab bending mechanism.
