Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0031] This application provides a cutting and feeding device for automatically cutting and feeding electrode tabs for welding, such as... Figure 1 As shown, the cutting and feeding device includes an unwinding mechanism 1, a cutting mechanism 2, a transport mechanism 3, a feeding mechanism 4, and a welding mechanism 5, which are arranged sequentially along the first direction X. The first direction X is the conveying direction of the electrode tab on the cutting and feeding device. The unwinding mechanism 1 is used to install the coil material 01 of the electrode tab to be cut. One end of the coil material 01 extends to the cutting mechanism 2. The cutting mechanism 2 is used to cut the coil material 01 into electrode tabs. The transport mechanism 3 is used to transport the electrode tab to the feeding mechanism 4. The feeding mechanism 4 is used to place the electrode tab to the welding mechanism 5. The welding mechanism 5 is used to weld the electrode tab and the electrode sheet.

[0032] In this embodiment, the roll material 01 is pulled out from the unwinding mechanism 1 to the cutting mechanism 2. The cutting mechanism 2 cuts the roll material 01 into sheet-shaped tabs with a preset shape and size. Then, the tabs are transported by the transport mechanism 3 to the vicinity of the feeding mechanism 4. The feeding mechanism 4 places the tabs on the welding mechanism 5 so that the tabs and the electrode sheets are stacked. Finally, the welding mechanism 5 welds and fixes the tabs and the electrode sheets. In this embodiment, the electrode sheets cut into sheet form are directly transported by the transport mechanism 3 to the loading mechanism 4, eliminating the operation of loading the tabs into the magazine, and thus eliminating the operation of the loading mechanism 4 picking up the tabs from the magazine. This also reduces the loading difficulty of the loading mechanism 4, which is conducive to shortening the loading cycle of the tabs, and thus helps to shorten the overall processing cycle of the cell and lithium battery. In addition, by omitting the operation of the loading mechanism 4 picking up the tabs from the magazine, problems such as tab wrinkling, damage, displacement, and reversal caused by the loading mechanism 4 during the material picking process are reduced, thereby improving the accuracy of the loading mechanism 4 in placing the tabs on the welding mechanism 5 in terms of position, angle, and direction.

[0033] The structure of the unwinding mechanism 1 is as follows: Figure 2 As shown, the unwinding mechanism 1 includes an air shaft 11, which is used to fix the coil 01 and to drive the coil 01 to rotate around the axis of the air shaft 11.

[0034] In this embodiment, the roll material 01 is fixed by the air expansion shaft 11, which simplifies the fixing method and structure of the roll material 01, thereby simplifying the structure of the unwinding mechanism 1 and reducing the cost of the unwinding mechanism 1.

[0035] like Figure 2 As shown, the unwinding mechanism 1 also includes multiple guide rollers 12 along the second direction Z. The guide rollers 12 are used to abut against the coil material 01 to tighten the coil material 01, reduce the risk of local accumulation of the coil material 01 and wrinkles, thereby improving the yield of the tabs. The second direction Z is perpendicular to the first direction X.

[0036] like Figure 2 As shown, the unwinding mechanism 1 also includes a deviation correction device 13, located above or below the roll 01 along the second direction Z. The deviation correction device 13 is used to detect and correct the tilt angle of the roll 01. Specifically, as... Figure 3As shown, the correction device 13 includes a second driving member 131 for contacting the roll 01, a second driving member 132 and a second driving member 133 drivenly connected to the second driving member 131, along a third direction Y. The third direction Y is parallel to the axis of the air shaft 11 and perpendicular to the first direction X and the second direction Z. The second driving member 132 and the second driving member 133 are respectively connected to both sides of the second driving member 131. The second driving member 132 can drive one end of the second driving member 131 to move along the second direction Z, and the second driving member 133 can drive the other end of the second driving member 131 to move along the second direction Z, so that the second driving member 131 tilts, thereby making the second driving member 131 re-contact the tilted roll 01. That is, the second driving member 131 and the roll 01 are kept in contact by the second driving member 132 and the second driving member 133, which improves the tensioning effect of the roll 01, reduces the problems of wrinkles and curling edges caused by local bending and tilting of the roll 01, and further improves the yield of the tab.

[0037] like Figure 2 As shown, the unwinding mechanism 1 includes a first pressure roller 14 and a second pressure roller 15 distributed along the second direction Z. The first pressure roller 14 and the second pressure roller 15 are used to clamp the coil material 01. One of the first pressure roller 14 and the second pressure roller 15 can rotate clockwise around its own axis, and the other can rotate counterclockwise around its own axis to pull the coil material 01 along the first direction X.

[0038] In this embodiment, after the first pressure roller 14 and the second pressure roller 15 clamp the roll material 01, the first pressure roller 14 and the second pressure roller 15 rotate in opposite directions, so that frictional forces in the same direction are generated between the first pressure roller 14 and the roll material 01, and between the second pressure roller 15 and the roll material 01. Under the action of frictional force, the roll material 01 can be pulled out and extended to the cutting mechanism 2. In this embodiment, by pulling the roll material 01 by the opposite rotation of the first pressure roller 14 and the second pressure roller 15, the feeding operation of the roll material 01 at the cutting mechanism 2 is simplified, thereby simplifying the structure of the cutting and feeding device and reducing the cost of the cutting and feeding device.

[0039] like Figure 4 As shown, the cutting mechanism 2 includes a cutting platform 21, a cutting component 22, and a pressure plate 23. Along the first direction X, the cutting component 22 is located between the pressure plate 23 and the first pressure roller 14. The first pressure roller 14 and the second pressure roller 15 are used to clamp and fix one side of the roll material 01, and the pressure plate 23 and the cutting platform 21 are used to press and fix the other side of the roll material 01. The cutting component 22 is used to cut the roll material 01.

[0040] In this embodiment, one side of the roll material 01 is clamped and fixed by the first pressure roller 14 and the second pressure roller 15, and the other side is pressed and fixed by the pressure plate 23 and the cutting platform 21. This reduces the risk of the roll material 01 moving during the cutting process of the cutting part 22, thereby improving the cutting accuracy of the cutting mechanism 2 on the tabs, and thus improving the size and shape yield of the tabs.

[0041] Among them, such as Figure 4 As shown, the cutting mechanism 2 also includes a third driving member 24 and a fourth driving member 25. The third driving member 24 is driven to move the pressure plate 23 along the second direction Z, so that the pressure plate 23 moves closer to or away from the cutting platform 21. The fourth driving member 25 is driven to move the cutting member 22 along the second direction Z, so that the cutting member 22 moves closer to or away from the cutting platform 21.

[0042] In this embodiment, after the cutting mechanism 2 completes one cutting, the third driving member 24 and the fourth driving member 25 can drive the pressure plate 23 and the cutting member 22 away from the cutting platform 21 so as to facilitate the next cutting process.

[0043] like Figure 1 As shown, the transport mechanism 3 includes a conveyor belt 31 and a transfer platform 32. The conveyor belt 31 is used to transport the tabs at the cutting mechanism 2 to the transfer platform 32.

[0044] In this embodiment, the electrode tabs are transported by the conveyor belt 31, which simplifies the transport structure of the electrode tabs, that is, simplifies the structure of the transport mechanism 3 and reduces the transport cost of the electrode tabs; and the conveyor belt 31 can transport multiple electrode tabs at the same time, which improves the transport efficiency of the transport mechanism for the electrode tabs.

[0045] like Figure 1 As shown, the cutting and feeding device also includes a first detection element 33, which is distributed along the second direction Z with the conveyor belt 31. The first detection element 33 is used to detect whether the electrode tab is a qualified electrode tab or an unqualified electrode tab. The cutting and feeding device also includes a storage box 6, which is located on the side of the transfer platform 32 away from the conveyor belt 31 along the first direction X. The first detection element 33 is electrically connected or signal connected to the feeding mechanism 4. The feeding mechanism 4 is used to place qualified electrode tabs onto the welding mechanism 5 and unqualified electrode tabs into the storage box 6.

[0046] In this embodiment, the size, shape, and other parameters of the electrode tabs are first detected by the first detection element 33, and then the qualified electrode tabs are placed onto the welding mechanism 5 by the feeding mechanism 4, thereby improving the yield of the battery cells and lithium batteries. The storage box 6 for accommodating unqualified electrode tabs facilitates their reuse, thereby reducing the cost of the battery cells and lithium batteries. Simultaneously, it reduces the risk of safety issues arising from the accumulation of unqualified electrode tabs near the cutting and feeding device.

[0047] During the cutting of the tabs, the coil 01 gradually decreases in size. Typically, the beginning of another coil 01 is bonded to the end of the coil 01 currently in use using tape to extend the length of the coil 01. When tape is present on the tabs, the tabs cannot be welded to the electrode sheet. Therefore, as... Figure 1 As shown, the transport mechanism 3 includes a color mark sensor 34, which is distributed along the second direction Z with the transfer platform 32. The color mark sensor 34 is electrically or signal-connected to the loading mechanism 4. The color mark sensor 34 is used to detect whether the electrode tab is a qualified electrode tab or an unqualified electrode tab according to the color on the electrode tab. The loading mechanism 4 is used to place qualified electrode tabs onto the welding mechanism 5 and unqualified electrode tabs onto the storage box 6.

[0048] The working principle of the color mark sensor 34 is based on the difference in reflection or transmission of light on surfaces of different colors. Specifically, the color mark sensor 34 emits test light onto the surface of the tab. The test light is reflected back to the color mark sensor 34 by the surface of the tab. Since the intensity and wavelength of the light reflected back from surfaces of different colors are different, the color mark sensor 34 identifies the color of the tab based on the intensity and wavelength of the reflected light. When the color of the tab surface matches the calibrated color, the color mark sensor 34 determines that the tab is unqualified. If there is tape on the tab surface, the color mark sensor 34 can directly or indirectly control the feeding mechanism 4, which places the unqualified tab into the storage box 6.

[0049] In this embodiment, the presence of adhesive tape on the surface of the tab is detected by the color mark sensor 34, which reduces the cost of manual identification and shortens the identification cycle, thereby helping to shorten the processing cycle of the battery cell and lithium battery. In addition, it also reduces the risk that the battery cell cannot work properly due to the welding of the tab with adhesive tape to the electrode sheet, thereby improving the processing yield of the battery cell and lithium battery.

[0050] like Figure 1 and Figure 5As shown, the feeding mechanism 4 includes a first fixed frame 41, a second fixed frame 42, a third fixed frame 43, and a feeding robot 44. The first fixed frame 41 is installed on the transport mechanism 3, and the second fixed frame 42 is installed on the welding mechanism 5. Along the first direction X, the two ends of the third fixed frame 43 are connected to the first fixed frame 41 and the second fixed frame 42 respectively. The third fixed frame 43 is provided with a slide rail 431 extending along the first direction X. The feeding robot 44 cooperates with the slide rail 431 and can move along the slide rail 431.

[0051] In this embodiment, the slide rail 431 can guide the movement of the loading robot 44, thereby improving the accuracy of the movement direction of the loading robot 44, and thus improving the working stability and reliability of the loading robot 44.

[0052] The movement of the loading robot 44 in the first direction X is driven by a drive unit (not shown in the figure). The drive unit can be directly connected to the loading robot 44 or indirectly connected to the loading robot 44 through a lead screw.

[0053] like Figure 6 and Figure 7 As shown, the welding mechanism 5 includes a welding head 51 and a welding seat 52 distributed along the second direction Z. The welding seat 52 is used to support the electrode and the electrode tab, and the welding head 51 is used to weld and fix the electrode and the electrode tab. The welding mechanism 5 also includes a shaping platform 53 and a second detection element 54 distributed along the second direction Z. The loading mechanism 4 is used to place the electrode tab on the transport mechanism 3 onto the shaping platform 53. The second detection element 54 is used to detect the position and angle relationship between the electrode tab and itself. The shaping platform 53 is used to adjust the position and angle of the electrode tab according to the detection result of the second detection element 54. The loading mechanism 4 is used to place the adjusted electrode tab onto the welding seat 52.

[0054] In this embodiment, after the loading robot 44 places the electrode tab on the shaping platform 53, the shaping platform 53 can adjust the placement position and angle of the electrode tab by its own movement and rotation. After that, the loading robot 44 places the adjusted electrode tab on the welding base 52, which can improve the accuracy of the placement angle of the electrode tab on the welding base 52, thereby helping to improve the welding quality of the electrode tab and the electrode sheet.

[0055] The shaping platform 53 is a common existing structure, and the specific structure of the shaping platform 53 will not be described in detail in this embodiment.

[0056] like Figure 6 and Figure 7 As shown, the welding mechanism 5 includes a welding machine 55 and an adjustment device 56. The welding machine 55 is connected to the welding head 51 through the adjustment device 56, which is used to increase or decrease the vibration frequency of the welding head 51.

[0057] In this embodiment, the welding machine 55 is used to control the welding head 51 to vibrate at high frequency. The energy of the high-frequency vibration of the welding head 51 is used to weld the tab and the electrode together, that is, the tab and the electrode are welded and fixed by ultrasonic welding. The welding machine 55 and the welding head 51 are connected by an adjustment device 56, which can adjust the vibration frequency of the welding head 51 to adjust the welding quality of the welding mechanism 5.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
