Description

Technical Field

[0001] This application relates to the field of soft-pack lithium battery assembly technology, specifically to a battery waste edge cutting device. Background Technology

[0002] Currently, pouch lithium batteries are mostly square and cylindrical in shape, and are widely used in 3C fields such as mobile phones, Bluetooth headsets, laptops, and smartwatches. However, with the continuous iteration and technological updates of electronic products in the 3C field, the regular shape of batteries, as an important energy device for end-users, is gradually becoming insufficient to accommodate the space requirements of increasingly powerful electronic devices.

[0003] Currently, in the later stages of manufacturing of pouch batteries, excess waste material on both sides needs to be precisely cut to ensure a certain cutting accuracy, so as to provide accurate edge precision for subsequent processes such as double-folding and single-folding adhesive coating.

[0004] In related technologies, the traditional cutting mechanism in the precision cutting process is mainly a die-cutting mechanism, which uses upper and lower dies for mechanical cutting. However, this method has the following shortcomings:

[0005] 1. Traditional die cutting places great demands on the machining and installation accuracy of the cutting die. If the machining and installation accuracy are insufficient, it will be unable to cut off the waste material or produce burrs, which may puncture the subsequent aluminum-plastic film encapsulation structure.

[0006] 2. Traditional die-cutting molds are cut to a fixed width. Long-term cutting will cause burrs and wear on the mold, requiring regular return to the factory for maintenance and repair, resulting in a shorter lifespan. Utility Model Content

[0051] Currently, pouch lithium batteries are mostly square and cylindrical in shape, and are widely used in 3C fields such as mobile phones, Bluetooth headsets, laptops, and smartwatches. However, with the continuous iteration and technological updates of electronic products in the 3C field, the regular shape of batteries, as an important energy device for end-users, is gradually becoming insufficient to accommodate the space requirements of increasingly powerful electronic devices.

[0052] Currently, in the later stages of manufacturing of pouch batteries, excess waste material on both sides needs to be precisely cut to ensure a certain cutting accuracy, so as to provide accurate edge precision for subsequent processes such as double-folding and single-folding adhesive coating.

[0053] In related technologies, the traditional cutting mechanism in the precision cutting process is mainly a die-cutting mechanism, which uses upper and lower dies for mechanical cutting. However, this method has the following shortcomings:

[0054] 1. Traditional die cutting places great demands on the machining and installation accuracy of the cutting die. If the machining and installation accuracy are insufficient, it will be unable to cut off the waste material or produce burrs, which may puncture the subsequent aluminum-plastic film encapsulation structure.

[0055] 2. Traditional die-cutting molds use a fixed width for cutting, which leads to burrs and wear over time, requiring regular return to the factory for maintenance and resulting in a short lifespan. Therefore, this application provides a battery waste edge cutting device to solve or improve the technical problems of failing to cut waste materials and generating burrs.

[0056] The following is combined with Figures 1 to 4 This describes an embodiment of the present application.

[0057] According to embodiments of this application, such as Figure 1 and Figure 2 As shown, a battery waste edge cutting device is provided, including: a bracket 1, a cutting wire 2, a first driving mechanism 3, a second driving mechanism 4, a battery clamping mechanism 5, and an image recognition mechanism 6.

[0058] Specifically, the bracket 1 is provided with multiple support parts 101;

[0059] The cutting wire 2 is connected end to end and is wound around multiple support parts 101 in sequence, and is slidably connected to each support part 101. The cutting wire 2 is used to cut the waste material 10 of the battery 9.

[0060] The driving part of the first driving mechanism 3 is connected to the cutting wire 2 in a transmission connection, and is suitable for driving the cutting wire 2 to slide around multiple support parts 101;

[0061] The drive unit of the second drive mechanism 4 is adapted to move in a plane;

[0062] The battery clamping mechanism 5 is mounted on the drive part of the second drive mechanism 4, which is adapted to drive the battery 9 to move relative to the cutting wire 2.

[0063] The image recognition mechanism 6 is used to collect the location information of the waste material 10 of the battery 9, and is electrically connected to the first drive mechanism 3 and the second drive mechanism 4.

[0064] In this embodiment, such as Figure 1 and Figure 2 As shown, the battery 9 is installed on the battery clamping mechanism 5. The image recognition mechanism 6 takes a picture of the battery 9, analyzes and obtains the position information of the waste material 10 of the battery 9, and transmits the obtained position information of the waste material 10 of the battery 9 to the first drive mechanism 3 and the second drive mechanism 4. The first drive mechanism 3 drives the cutting wire 2 to rotate around the multiple support parts 101. The second drive rod mechanism drives the battery clamping mechanism 5 to move in the plane and approach the cutting wire 2. The cutting wire 2 cuts the waste material 10 of the battery 9. The first drive mechanism 3 drives the cutting wire 2 to rotate, which can increase the relative speed when in contact with the waste material 10 of the battery 9, improve the flatness of the cut surface, and prevent burrs from appearing on the cut section.

[0065] In some embodiments, such as Figure 1 As shown, the second drive mechanism 4 includes an X-axis moving module 401 and a Y-axis moving module 402. The Y-axis moving module 402 is mounted on the X-axis moving module 401. The X-axis moving module 401 can drive the Y-axis moving module 402 to move along the X direction. The battery clamping mechanism 5 is mounted on the Y-axis moving module 402.

[0066] Specifically, such as Figure 1 As shown, the X-axis moving module 401 includes an X-axis mounting plate and an X-axis driving mechanism. The X-axis driving mechanism is mounted on the X-axis mounting plate, and the Y-axis driving module is slidably connected to the X-axis mounting plate. The driving end of the X-axis driving mechanism is connected to the Y-axis driving module.

[0067] Specifically, such as Figure 1 As shown, the X-axis drive mechanism can be a cylinder or a ball screw mechanism. Both cylinder and ball screw mechanisms are related technologies and will not be described in detail here.

[0068] In some embodiments, the Y-axis moving module 402 includes a Y-axis mounting plate and a Y-axis driving mechanism. The Y-axis driving mechanism is mounted on the Y-axis mounting plate, the battery clamping mechanism 5 is slidably connected to the Y-axis mounting plate, and the driving end of the Y-axis driving mechanism is connected to the battery clamping mechanism 5.

[0069] Specifically, such as Figure 1 As shown, the Y-axis drive mechanism can be a cylinder or a ball screw mechanism. Both cylinder and ball screw mechanisms are related technologies and will not be described in detail here.

[0070] In some embodiments, such as Figure 1As shown, the battery clamping mechanism 5 includes: a plate 501, a first clamping plate 502, a second clamping plate, and a driving clamping member. The first clamping plate 502 is fixed on the plate 501, and the second clamping plate is slidably connected to the plate 501. A clamping gap for installing the battery 9 is provided between the first clamping plate 502 and the second clamping plate. The driving clamping member is installed on the plate 501, and its driving end is connected to the second clamping plate, driving the second clamping plate to approach the first clamping plate 502 and clamp the battery 9.

[0071] Specifically, the driving clamping component can be a spring, a cylinder, or a ball screw mechanism.

[0072] In some embodiments, such as Figure 1 As shown, the image recognition mechanism 6 includes a support frame 601 and a laser profilometer 602. The laser profilometer 602 is mounted on the support frame 601. The laser profilometer 602 is used to collect the contour of the battery 9 and identify the position of the waste material 10 of the battery 9. It also transmits the position information of the battery 9 and the waste material 10 of the battery 9 to the first drive mechanism 3, the X-axis drive mechanism and the Y-axis drive mechanism. Through the cooperation of the X-axis drive mechanism and the Y-axis drive mechanism, the waste material 10 of the battery 9 is cut.

[0073] In another implementation, such as Figure 1 As shown, the image recognition mechanism 6 can also be a camera. The camera takes a picture of the battery 9 and generates a distribution image of the waste material 10 of the battery 9. The distribution image information of the waste material 10 of the battery 9 is transmitted to the X-axis drive mechanism and the Y-axis drive mechanism. Through the cooperation of the X-axis drive mechanism and the Y-axis drive mechanism, the waste material 10 of the battery 9 is cut.

[0074] In one embodiment, such as Figure 1 and Figure 2 As shown, the cutting wire 2 is wound around multiple support parts 101 in sequence to form two cutting units 201. The two cutting units 201 are arranged in parallel and a cutting gap is provided between them. The two cutting units 201 are used to cut the waste material 10 on both sides of the battery 9.

[0075] In this embodiment, such as Figure 1 and Figure 2 As shown, the two cutting units 201 are used to cut the waste material 10 on both sides of the battery 9. The two cutting units 201 are arranged in parallel to ensure the symmetry of the cutting on both sides and to cut both sides of the battery 9 at the same time, thereby improving efficiency.

[0076] In one embodiment, such as Figure 2 and Figure 3 As shown, the support 1 includes:

[0077] The fixing frame 102 is provided with a guide part 1021;

[0078] The deformation frame 103 has multiple support parts 101 disposed on it. The deformation frame 103 is provided with a sliding end 1031 and a connecting end 1032. The connecting end 1032 is connected to the fixed frame 102, and the sliding end 1031 is slidably connected to the guide part 1021. When the sliding end 1031 slides along the guide part 1021, it can change the shape of the deformation frame 103 to adjust the cutting spacing.

[0079] In this embodiment, such as Figure 2 and Figure 3 As shown, the cutting wire 2 is set on the deformation frame 103, and when the sliding end 1031 of the deformation frame 103 slides along the guide portion 1021, the cutting spacing can be adjusted, and the waste material 10 of batteries 9 of various sizes and widths can be cut.

[0080] In some embodiments, the guide portion 1021 is a groove or a guide rail, and the guiding direction of the guide portion 1021 is a third direction M.

[0081] In some embodiments, a third driving mechanism is also included. The third driving mechanism is mounted on the fixed frame 102, and its driving end is connected to the sliding end 1031. The sliding end 1031 is driven to slide along the guide portion 1021. The third driving mechanism is electrically connected to the image recognition mechanism 6.

[0082] Specifically, the third drive mechanism can be a cylinder or a ball screw mechanism.

[0083] In one embodiment, such as Figure 2 and Figure 3 As shown, there are four support parts 101, and the cutting wire 2 is wound around the four support parts 101 to form two cutting units 201.

[0084] The deformable frame 103 includes:

[0085] The first link 1033 has a support part 101 at both ends;

[0086] The center of the second link 1034 is hinged to the center of the first link 1033. Both ends of the second link 1034 are provided with support parts 101. One end of the first link 1033 is a connecting end 1032, which is rotatably connected to the fixed frame 102. One end of the second link 1034 is a sliding end 1031. The two cutting units 201 are arranged opposite to each other along the guiding direction of the guide part 1021.

[0087] In this embodiment, such as Figure 2 and Figure 3As shown, the first link 1033 and the second link 1034 are centrally hinged, forming a cross-shaped rotating frame. Support parts 101 are respectively provided at the four ends of the cross-shaped rotating frame. The cutting wire 2 is wound around the four support parts 101 to form a rectangle. The two cutting units 201 are arranged left and right. When the sliding end 1031 of the second link 1034 slides along the guide part 1021, the height and width of the cross-shaped rotating frame change synchronously. When the height increases, the width narrows, and when the height decreases, the width widens. The change in the width of the cross-shaped rotating frame can adjust the cutting distance between the two cutting units 201.

[0088] In one embodiment, such as Figure 2 and Figure 3 As shown, the bracket 1 also includes:

[0089] A connecting plate 104 is fixed on a fixing frame 102. A first sliding groove 1041 is provided on the connecting plate 104 along the first direction W. The connecting end 1032 of the first connecting rod 1033 is rotatably connected to the connecting plate 104. The end of the second connecting rod 1034 away from the sliding end 1031 is slidably connected to the first sliding groove 1041.

[0090] The sliding plate 105 is slidably connected to the guide part 1021. The sliding plate 105 has a second groove 1051 along the first direction W. The end of the first connecting rod 1033 away from the connecting end 1032 is slidably connected to the second groove 1051. The sliding end 1031 of the second connecting rod 1034 is rotatably connected to the sliding plate 105.

[0091] In this embodiment, such as Figure 2 and Figure 3 As shown, the end of the first connecting rod 1033 away from the connecting end 1032 is slidably connected to the second slide groove 1051, and the end of the second connecting rod 1034 away from the sliding end 1031 is slidably connected to the first slide groove 1041, which can maintain the stability of the cross rotating frame rotation when adjusting the width of the cross rotating frame.

[0092] In one embodiment, such as Figure 2 and Figure 3 As shown, the cutting wire 2 is wound around four support parts 101 to form a first connecting unit 202 and a second connecting unit 203 arranged opposite to each other along the first direction W.

[0093] It also includes a tensioning device 7. A sliding part 1022 is provided on the fixed frame 102 along the first direction W. The tensioning device 7 is slidably connected to the sliding part 1022. The tensioning device 7 is pressed against the first connecting unit 202 to tension the two cutting units 201.

[0094] The drive unit of the first drive mechanism 3 is connected to the second connecting unit 203 via a transmission connection.

[0095] In this embodiment, to avoid affecting the width variation of the cross rotating component, the length of the cutting wire 2 is sufficient to meet the maximum distance connecting the four ends of the cross rotating frame. Therefore, the tensioning device 7 presses against the first connecting unit 202 to tension the two cutting units 201 and the second connecting unit 203. When the cross rotating frame deforms, the position of the second connecting unit 203 along the first direction W remains unchanged, while the first connecting unit 202 moves up and down along the first direction W.

[0096] In one embodiment, such as Figure 2 and Figure 3 As shown, the tensioning device 7 includes:

[0097] Slider 701 is slidably connected to sliding part 1022;

[0098] Tensioner 702 is rotatably connected to slider 701 and rolls against first connecting unit 202.

[0099] The elastic element has one end connected to the fixed frame 102 and the other end connected to the slider 701. Under the elastic force of the elastic element, the slider 701 is driven to slide along the sliding part 1022 so that the tensioning wheel 702 is pressed against the first connecting unit 202.

[0100] Specifically, the elastic element can be a spring or a sheet.

[0101] In one embodiment, such as Figure 2 and Figure 3 As shown, the first drive mechanism 3 includes:

[0102] A drive motor 301 is mounted on a fixed frame 102, and a drive wheel 302 is mounted on the output shaft of the drive motor 301.

[0103] The clamping wheel 303 is rotatably connected to the fixed frame 102, and the second connecting unit 203 is clamped between the driving wheel 302 and the clamping wheel 303.

[0104] In this embodiment, such as Figure 2 and Figure 3 As shown, the position of the second connecting unit 203 along the first direction W remains unchanged, and the drive wheel 302 and clamping wheel 303 on the drive motor 301 can drive the cutting wire 2 to rotate around the four support parts 101.

[0105] In one embodiment, such as Figure 2 and Figure 3 As shown, it also includes a heating mechanism 8, which is mounted on the fixed frame 102 and is used to heat the second connecting unit 203.

[0106] In this embodiment, heating the cutting wire 2 by the heating mechanism 8 can increase the cutting speed. The increased cutting speed can improve the flatness of the cut surface and prevent burrs from forming.

[0107] Specifically, the heating mechanism 8 can be an electromagnetic heating mechanism.

[0108] In one embodiment, such as Figure 2 and Figure 4 As shown, the deformable frame 103 also includes: four mounting shafts 1035, the first ends of the four mounting shafts 1035 being respectively connected to the two ends of the first connecting rod 1033 and the two ends of the second connecting rod 1034, and each mounting shaft 1035 extending along the second direction N;

[0109] The support part 101 is a pulley, and the four pulleys are rotatably connected to the second end of the four mounting shafts 1035;

[0110] In this context, the second direction N is perpendicular to the first direction W.

[0111] In this embodiment, such as Figure 2 and Figure 4 As shown, the four mounting shafts 1035 can move the cutting wire 2 away from the deformation frame 103 along the second direction N, providing space for the cutting wire 2 to cut the waste material 10 of the battery 9, preventing the battery 9 from contacting the deformation frame 103 and affecting the cutting of the waste material 10 of the battery 9. The cutting wire 2 is wound on four pulleys to facilitate the rotation of the cutting wire 2.

[0112] The following is an example, combined with Figures 1 to 4 A comprehensive explanation of all the above-mentioned plans is provided.

[0113] The battery 9 is clamped on the first clamping plate 502 and the second clamping plate. The laser profilometer 602 is used to collect the profile of the battery 9 and identify the position of the waste material 10 of the battery 9. The position information of the battery 9 and the waste material 10 is transmitted to the first drive mechanism 3, the X-axis drive mechanism and the Y-axis drive mechanism. Through the cooperation of the X-axis drive mechanism and the Y-axis drive mechanism, the waste material 10 of the battery 9 is cut.

[0114] The drive wheel 302 and clamping wheel 303 on the drive motor 301 can drive the cutting wire 2 to rotate around the four pulleys, which can increase the cutting speed. The increased cutting speed can improve the flatness of the cut surface of the waste material 10 of the battery 9 and prevent burrs. At the same time, the electromagnetic heating mechanism 8 heats the cutting wire 2, further increasing the cutting speed and improving the flatness of the cut surface of the waste material 10 of the battery 9.

[0115] The third drive mechanism is installed on the fixed frame 102, and drives the sliding end 1031 to slide along the guide part 1021, changing the width of the cross rotating frame and adjusting the cutting distance between the two cutting units 201 to adapt to batteries 9 of different widths.

[0116] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
