Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion batteries, and more specifically to a battery tab cutting system. Background Art

[0002] As a core component of the new energy industry, lithium batteries have a direct impact on the popularity and safety of electric vehicles and energy storage systems. This type of battery is favored for its high energy density and long life. With the rapid development of the electric vehicle and energy storage industries, the safety issues of battery technology have attracted widespread attention. In order to solve the problem of internal short circuits, the industry has adopted a variety of battery assembly and management technologies, especially in the treatment of battery tabs, and has tried a variety of cutting and welding technologies in order to improve the overall safety performance of the battery.

[0003] In the prior art, the production process of lithium batteries mainly includes the welding and connection of the tabs. The commonly used method is to weld the copper tabs to the copper connecting pieces and the aluminum tabs to the aluminum connecting pieces. This welding process usually uses ultrasonic welding technology, which is fixed by pressing the welding head down before welding. In addition, the processing of the battery tabs also includes tab cutting to remove the excess parts caused by welding, so as to prevent the tabs from being too long and interfering with the welding of the opposite tabs, or affecting the appearance and performance of the battery cell.

[0004] However, existing cutting and welding technologies have many shortcomings. During the tab cutting process, the use of hardware cutting knives may cause the material to draw, and inaccurate cutting positions may also cause the tabs to tear. These problems not only affect the structural integrity of the battery, but may also cause copper and aluminum foil scraps to fall into the battery cell. These metal scraps can cause short circuits inside the battery cell, especially during charging, and are very likely to penetrate the diaphragm and cause spontaneous combustion or fire.

[0005] On the other hand, although laser cutting technology provides a potential alternative, this method also has stability issues. During the laser cutting process, the instability of laser power and welding shielding gas may lead to uneven cutting and the generation of molten beads of varying sizes, which will also affect the safety and performance of the battery. These technical defects reveal key issues in lithium battery production that need to be solved through technological innovation to ensure the safety and reliability of battery products.

[0006] In short, the existing lithium battery production technology has many defects in the welding and cutting process of the tabs. The metal cutting process is prone to material drawing and tab tearing, increasing the risk of metal chips entering the battery cell, which may cause internal short circuits or spontaneous combustion of the battery; and the instability of the cutting process of laser cutting technology is also very likely to cause uneven cutting, affecting the overall performance and safety of the battery.

[0056] refer to Figure 1 In an embodiment of the present application, a battery tab cutting system 100 is provided, comprising:

[0057] A suspension device 1 and a laser cutting device 2 arranged on the suspension device 1;

[0058] The laser cutting device 2 is a cutting array composed of a plurality of laser cutting units 21;

[0059] In the cutting array, the laser light source points emitted by the plurality of laser cutting units 21 are arranged to form a transverse linear cutting light source 2121;

[0060] The length direction of the transverse linear cutting light source 2121 is parallel to the plane of the to-be-cut battery tab 41 of the target battery 4;

[0061] The length of the transverse linear cutting light source 2121 is not less than the width of the target battery 4 .

[0062] As mentioned above, the laser cutting device 2 includes multiple laser cutting units 21, and the multiple laser cutting units 21 constitute a cutting array, so that the laser light source points emitted by each laser cutting unit 21 are arranged horizontally to form a strip-shaped laser light source line, that is, a horizontal linear cutting light source 2121.

[0063] The conventional laser cutting method is to move the laser head through the laser light source point so that the laser light source point moves on the surface of the cutting position of the battery tab 41 to be cut, thereby achieving cutting.

[0064] In the embodiment of the present application, the laser light source points emitted by multiple laser cutting units 21 are arranged to form a horizontal linear cutting light source 2121. On the surface of the cutting position of the battery tab 41 to be cut, there is no need to move the laser cutting unit 21 for cutting, but a one-time forming cutting is performed.

[0065] As mentioned above, multiple laser cutting units 21 are connected to the suspension device 1, and the battery tab 41 to be cut of the target battery 4 is placed below the laser cutting unit 21. Each laser cutting unit 21 emits a laser beam to a specific position of the battery tab 41 to be cut below, thereby forming a strip-shaped laser light source line on the surface of the battery tab 41 to be cut, that is, a transverse linear cutting light source 2121.

[0066] It should be noted that the multiple laser cutting units 21 can adjust the length of the transverse linear cutting light source 2121 by opening or closing some of the laser cutting units 21, or by adjusting the position, adjusting the light overlapping position of the laser cutting unit 21, and so on.

[0067] In summary, the battery tab cutting system 100 provided in the embodiment of the present application, through the laser light source points emitted by multiple laser cutting units 21 are arranged to form a strip-shaped horizontal linear cutting light source 2121. The cutting process is fast and stable, and it can be cut in a short time at one time. There is no cutting process from left to right, which can ensure the stability of the cutting process. The molten bead at the tab cutting position is better and the formation of slag is greatly reduced.

[0068] Furthermore, the length of the transverse linear cutting light source 2121 is 20 mm-100 mm.

[0069] As mentioned above, the length of the transverse linear cutting light source 2121 is obtained by arranging and adjusting the laser light source points emitted by multiple laser cutting units 21. It can be set according to the width of the pole ear that needs to be cut. The length is 20mm-100mm, which can meet the cutting requirements of different types of batteries.

[0070] For example, the 3914895-50Ah tab is 20mm wide, and the laser light source T can be adjusted to 20mm for accurate cutting, which can save energy consumption and cutting processing time.

[0071] For further reference, Figure 2 The laser cutting unit 21 includes an adjustment mechanism 211 and a laser emitting mechanism 212 connected to the adjustment mechanism 211 .

[0072] As mentioned above, the adjustment mechanism 211 is connected to the laser emitting mechanism 212. The laser emitting mechanism 212 is a mechanism for emitting a laser beam, which may include but is not limited to a laser head, a heat dissipation device (such as a liquid nitrogen cooling circulation system), and a dust suction device (for synchronously sucking out debris).

[0073] As mentioned above, the adjustment mechanism 211 is used to adjust the position of the laser emitting mechanism 212, so as to form a strip-shaped laser light source line on the surface of the battery tab 41 to be cut.

[0074] For further reference, Figure 3 , the adjustment mechanism 211 includes a movable base 2111;

[0075] The laser emitting mechanism 212 is connected to the movable base 2111 ; the movable base 2111 is connected to the suspension device 1 , and the position thereof can be adjusted through the suspension device 1 .

[0076] As mentioned above, the movable base 2111 can be moved relative to the suspension device 1 to adjust the position of the corresponding laser emitting mechanism 212 .

[0077] Furthermore, the mobile base 2111 includes a mobile connecting member 21111, a first transmission mechanism 21112 and a first motor 21113; the mobile connecting member 21111 is provided with a first mobile pulley 21114;

[0078] The movable connecting member 21111 is connected to the suspension device 1 via the first movable pulley 21114;

[0079] One end of the first transmission mechanism 21112 is connected to the first motor 21113 and the other end is connected to the first moving pulley 21114 .

[0080] As mentioned above, the mobile base 2111 is a part of the entire laser cutting device 2, and its main function is to provide mobile support and precise positioning of the laser emitting mechanism 212. The technology and functions of this component can be subdivided into the following aspects:

[0081] Mobile connector 21111: As the core part of the mobile base 2111, it connects various mechanical components and transmission systems to ensure the coordinated movement of the entire base.

[0082] The first movable pulley 21114 is installed on the movable connecting member 21111 and connected to the suspension device 1 through a pulley system. The pulley system can reduce friction and make the movement of the laser emitting mechanism 212 more stable.

[0083] First transmission mechanism 21112 : The transmission mechanism connects the first motor 21113 and the first moving pulley 21114 , and is responsible for transmitting power and controlling the precise position adjustment of the moving base 2111 .

[0084] First motor 21113: The motor provides necessary power for the transmission mechanism, supporting the mobile base 2111 to move along a predetermined path and position.

[0085] The mobile base 2111 can be adjusted in position with the help of the suspension device 1, which is the key to achieving controlled laser precision cutting. The position adjustment depends on the coordinated work of the motor and the transmission mechanism to ensure that the laser emitting mechanism 212 can be aligned with the correct position of the battery tab. Through the fine regulation of the first motor 21113 and the transmission mechanism, the mobile base 2111 can be accurately positioned at a specific position, which is crucial for high-precision cutting work.

[0086] The design of the mobile base 2111 allows the laser cutting device 2 to move within a larger range, increasing the ability to process battery tabs of different sizes and types. Through rapid and accurate position adjustment, a large number of different types of tab cutting tasks can be completed in a short time, improving production efficiency. Automated movement and adjustment reduce human errors during operation and improve the reliability of the production process.

[0087] For further reference, Figure 4 , the mobile base 2111 further includes a hinge part 21115, a second transmission mechanism 21116 and a second motor 21117;

[0088] The laser emitting mechanism 212 is hinged to the hinge part 21115 through a pin shaft, and the second transmission mechanism 21116 is connected to the pin shaft, and the other end is connected to the second motor 21117, so that the laser emitting mechanism 212 can adjust its angle relative to the base through the second transmission mechanism 21116 driven by the second motor 21117.

[0089] As mentioned above, the hinged portion 21115 enables the laser emitting mechanism 212 to be hinged thereto via a pin shaft. Such a design allows the laser emitting mechanism 212 to rotate within a certain angle to meet different cutting requirements.

[0090] The second transmission mechanism 21116 and the second motor 21117 : By connecting the pin shaft and the second motor 21117 , the second transmission mechanism 21116 allows the laser emitting mechanism 212 to adjust its angle based on the drive of the second motor 21117 .

[0091] Through the design of the hinge 21115, the laser emitting mechanism 212 can adjust its angle of aiming at the battery tab to improve the adaptability and accuracy of cutting. The angle of the laser head can be adjusted according to the position and shape of different battery tabs to optimize the cutting path.

[0092] The technical solution of the hinged part 21115 can enhance the cutting adaptability, can adapt to battery tabs of different thicknesses and shapes, and improve the adaptability of the product.

[0093] As mentioned above, the hinged part 21115 may include two fixed ears, each of which is provided with a through hole. After the pin passes through the laser emitting mechanism 212 , both ends of the pin pass through the through hole to be connected to the hinged part 21115 .

[0094] The second transmission mechanism 21116 can be a driving wheel and a driven wheel connected by a belt, wherein the driving wheel is connected to the first motor 21113, and the driven wheel is connected to the pin shaft, and the pin shaft is fixedly connected to the laser emitting mechanism 212, so as to output power through the motor, and the driving wheel drives the driven wheel to rotate, and then drives the laser emitting mechanism 212 through the pin shaft to adjust the angle of the emission light beam.

[0095] For further reference, Figure 5 , the adjustment mechanism 211 further includes a lifting member 2112, a third transmission mechanism 2113 and a third motor 2114;

[0096] The lifting member 2112 is disposed between the hinge portion 21115 and the connecting member; one end of the third transmission mechanism 2113 is connected to the lifting member 2112, and the other end is connected to the third motor 2114;

[0097] The lifting member 2112 can adjust the length of the lifting member 2112 through the third transmission mechanism 2113 under the drive of the third motor 2114, so as to adjust the distance between the laser emitting mechanism 212 and the plane of the battery tab 41 to be cut of the target battery 4.

[0098] As mentioned above, the lifting member 2112 is located between the hinge portion 21115 and the connecting member, and can adjust its own length.

[0099] The third transmission mechanism 2113 and the third motor 2114 drive the lifting member 2112 to adjust the distance between the laser emitting mechanism 212 and the battery tab plane by changing the length of the lifting member 2112 .

[0100] The lifting member 2112 can adjust the distance between the laser emitting mechanism 212 and the battery tab 41 to be cut as needed to meet the cutting requirements of different heights and positions. By adjusting the distance between the laser head and the battery tab, the laser focus depth and cutting depth can be controlled to meet the different battery tab designs.

[0101] Enhance cutting accuracy and flexibility, allowing the laser head position to be fine-tuned to suit different battery tab specifications and production line requirements. Improve cutting quality, by precisely controlling the distance between the laser head and the battery tab, you can improve cutting accuracy and quality and reduce production defects.

[0102] For example, the third motor 2114 may be a stepper motor or a servo motor, and the lifting member 2112 may include a lead screw, a nut, and a bracket, etc.;

[0103] The third motor 2114 drives the nut to move up and down along the screw by rotating the screw. The nut is fixedly connected to the lifting member 2112, so the position of the lifting member 2112 changes with the nut, thereby adjusting its height relative to the base.

[0104] By controlling the rotation direction and the number of rotation steps or angle of the third motor 2114 through a program, the moving distance of the lifting member 2112 can be precisely controlled.

[0105] refer to Figure 6 The position and angle of each laser emitting mechanism 212 are adjusted by the adjustment mechanism 211, thereby forming a strip-shaped current cutting light source.

[0106] For further reference, Figure 7 , the suspension device 1 comprises a suspension mechanism;

[0107] The suspension mechanism includes two support columns 11, and a transverse suspension frame 12 disposed between the two support columns 11 and vertically connected to the support columns 11;

[0108] refer to Figure 8 , the transverse suspension 12 is provided with a moving groove;

[0109] The first movable pulley 21114 of the movable connecting member 21111 can be placed in the movable groove, and the movable connecting member 21111 of the adjustment mechanism 211 of the laser cutting unit 21 can move along the length direction of the movable groove.

[0110] As mentioned above, the suspension device 1 includes two symmetrically arranged support columns 11 and a "door"-shaped transverse suspension 12 arranged in the middle and vertically connected to the support columns 11, which provides a solid support and suspension structure for the entire laser cutting unit 21.

[0111] As mentioned above, the moving groove is provided on the transverse suspension 12 , which is a key component used to provide a moving limit mechanism for the laser cutting unit 21 and limit the moving range of the laser cutting unit 21 .

[0112] As mentioned above, the first movable pulley 21114 is mounted on the movable connecting member 21111 and placed in the movable groove, allowing the laser cutting unit 21 to move smoothly along the length direction of the transverse suspension 12.

[0113] The laser cutting unit 21 can move along the length of the moving slot so that the laser light source can be accurately aligned with the battery tab to be cut. This arrangement increases the accuracy and repeatability of the cutting. Through the solid structure of the support column 11 and the lateral suspension 12, the entire suspension device 1 provides sufficient stability, which is necessary for high-precision cutting work.

[0114] Due to the design of the first movable pulley 21114, the laser cutting unit 21 can be easily moved on the transverse suspension 12 to adapt to battery tabs of different widths and specifications. The stability of the suspension structure and the adjustability of the laser cutting unit 21 make the cutting process more precise, reduce errors, and improve product quality. This design allows the cutting device to be quickly adjusted to the appropriate position to adapt to battery tabs of different types and sizes, improving the flexibility and efficiency of the production line.

[0115] Furthermore, the battery tab cutting system 100 further includes a workbench 3;

[0116] The workbench 3 is provided with two parallel movable rails 31;

[0117] A second movable pulley 111 is disposed at the bottom end of the support column 11 , and the support column 11 is connected to the movable track 31 via the second movable pulley 111 , and can move along the length direction of the movable track 31 relative to the workbench 3 .

[0118] As mentioned above, the workbench 3 is equipped with two parallel movable rails 31 to provide a path for the movement of the support column 11 .

[0119] As mentioned above, the second movable pulley 111 is installed at the bottom end of the support column 11 and connected to the movable track 31 to allow the support column 11 to slide along the length direction of the movable track 31 of the workbench 3.

[0120] By arranging the movable track 31 on the workbench 3, the support column 11 (and the laser cutting device 2 thereon) can move along the track, thereby increasing the movable range and flexibility of the cutting device. The movable track 31 allows the position of the laser cutting device 2 to be adjusted quickly to accommodate batteries of different sizes and shapes, thereby improving production efficiency.

[0121] By enabling the laser cutting system to move over a wider range, it can adapt to different production needs more quickly, reducing adjustment time and increasing the flexibility and output of the production line.

[0122] For further reference, Fig. 9 The workbench 3 also includes a placement area 32, a recovery tank 33, a drop flap 34, a filter 35, an exhaust duct 36 and an exhaust device 37;

[0123] The placement area 32 is used to place the target battery 4;

[0124] The falling flap 34 is connected to the notch of the recovery groove 33 through the pin shaft;

[0125] The bottom of the recovery tank 33 is provided with a filter screen 35, and is connected to the exhaust device 37 through the exhaust duct 36;

[0126] The battery tab 41 to be cut of the target battery 4 is placed above the drop flap 34, and when the battery tab 41 to be cut is cut into tab fragments 42 and falls onto the drop flap 34, the drop flap 34 can flip according to the weight of the tab fragments 42, so that the tab fragments 42 are transferred into the recovery tank 33. Fig.10 , which is an exploded schematic diagram of the placement area 32, the recovery tank 33, the drop flap 34, the filter screen 35, the exhaust duct 36 and the exhaust equipment 37.

[0127] As mentioned above, the placement area 32 is a special area designed on the workbench 3 for placing the target battery 4. A fixing mechanism can be provided in the area to fix the target battery 4, thereby achieving stable cutting.
