[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following is for reference. Figures 1-9 A roller pressing apparatus 10 according to an embodiment of the first aspect of the present invention is described.

[0031] like Figure 1 and Figure 2 As shown, according to the first aspect of the present invention, the rolling device 10 is used to roll the welding area of ​​a battery cell 200. The battery cell 200 includes a shell and a cover. The shell is rectangular in shape and one side of the shell is open. The cover is closed on the open side of the shell. The periphery of the cover is welded to the periphery of the shell. The welding position of the cover and the shell is the welding area of ​​the battery cell 200. The welding area of ​​the battery cell 200 includes two long welding edges 201 and two short welding edges 202. The two long welding edges 201 extend along the width direction of the battery cell 200 and are spaced apart in the thickness direction of the battery cell 200. The two short welding edges 202 extend along the thickness direction of the battery cell 200 and are spaced apart in the width direction of the battery cell 200. The rolling device 10 of this embodiment is used to roll the two long welding edges 201 and the two short welding edges 202.

[0032] like Figures 3-5 As shown, the roller pressing device 10 of this embodiment includes: a base 101 and two roller pressing mechanisms 10a. The two roller pressing mechanisms 10a are disposed on the base 101 and are arranged along a first direction in the horizontal plane (e.g., Figure 4 The roller pressing mechanism 10a, arranged in the front-to-back direction as shown, includes a pressure roller 102, an angle detection and adjustment device 103, and a first drive member 111. The pressure rollers 102 of the two roller pressing mechanisms 10a are respectively used to press the welding areas on opposite sides of the battery cell 200. The angle detection and adjustment device 103 is connected to the pressure roller 102 and is used to detect and automatically adjust the relative angle between the pressure roller 102 and the battery cell 200. The first drive member 111 is connected to the pressure roller 102 and is used to drive the pressure roller 102 to move along a first direction to adjust the distance between the pressure rollers 102 of the two roller pressing mechanisms 10a.

[0033] like Figure 3 As shown, the pressure roller 102 extends vertically. The angle detection adjuster 103 is configured to detect the relative angle between the pressure roller 102 and the welding area of ​​the battery cell 200. The angle detection adjuster 103 is configured to adjust the angle of the pressure roller 102 according to the detected relative angle value, thereby adjusting the relative angle between the pressure roller 102 and the welding area of ​​the battery cell 200. This allows the angle of the pressure roller 102 to adapt to the angle of the welding area of ​​different models of battery cells 200, improving the rolling efficiency and rolling quality. Because the relative angle between the pressure roller 102 and the battery cell 200 is adjustable, the coverage rate of the welding area by the pressure roller 102 during rolling can be greater than or equal to 99%, thereby improving the rolling quality of the battery cell 200 and the finished product quality of the battery cell 200.

[0034] Furthermore, the first driving member 111 can adjust the distance between the pressure rollers 102 of the two rolling mechanisms 10a according to the width or thickness of the battery cell 200 in the first direction, so that the pressure rollers 102 of the two rolling mechanisms 10a can simultaneously roll the welding areas on opposite sides of the battery cell 200. In this way, the rolling device 10 can adjust the relative position of the pressure rollers 102 of the two rolling mechanisms 10a according to battery cells 200 of different specifications and sizes, thereby improving the applicability of the rolling device 10. At the same time, by adjusting the position of the battery cell 200, the rolling device 10 can also roll the long welding edge 201 and the short welding edge 202 of the battery cell 200 sequentially. In this way, the complete rolling of the welding area of ​​the battery cell 200 can be completed by one rolling device 10, improving the integration of the device and the rolling efficiency. In addition, by fine-tuning the relative position of the pressure rollers 102 of the two roller pressing mechanisms 10a in the first direction, the pressure applied to the battery cell 200 can be adjusted, so as to achieve precise and real-time control of the pressure, avoid damaging the battery cell 200, avoid ineffective pressure on the battery cell 200, improve the quality of roller pressing, and improve the automation level of the roller pressing device 10 in the roller pressing operation of the battery cell 200.

[0035] It should be noted that the dimension of the battery cell 200 in the first direction can be obtained by a sensor. The first drive member 111 is connected to the sensor and adjusts the relative position of the pressure rollers 102 of the two roller pressing mechanisms 10a according to the information obtained by the sensor.

[0036] According to the embodiments of the present invention, the roller pressing device 10, by setting an angle detection adjuster 103 and a first driving member 111, and by using the angle detection adjuster 103 and the first driving member 111 to automatically adjust the angle and relative position of the two pressure rollers 102, can adapt the roller pressing device 10 to different models of battery cells 200, improve the applicability of the roller pressing device 10, and can also accurately control the roller pressing pressure of the pressure rollers 102 on the battery cells 200, effectively avoiding damage or ineffective pressing of the battery cells 200, improving the roller pressing quality and roller pressing efficiency of the roller pressing device 10, and improving the finished quality of the battery cells 200.

[0037] In some embodiments of the present invention, such as Figure 4 As shown, the roller pressing mechanism 10a further includes: an adjusting plate 105, a pressure roller 102 disposed on the adjusting plate 105, an angle detection adjuster 103 disposed on the adjusting plate 105, and a first driving member 111 connected to the adjusting plate 105 for driving the adjusting plate 105 to move along a first direction. For example, the adjusting plate 105 can be a horizontally arranged flat plate. The pressure roller 102 and the angle detection adjuster 103 are disposed on the adjusting plate 105 in a second direction (e.g., ...). Figure 4At one end of the first drive member 111 (in the left-right direction shown in the diagram), the first drive member 111 is connected to the other end of the adjustment plate 105 in the second direction. In this embodiment, by setting the adjustment plate 105, the pressure roller 102 and the angle detection adjuster 103 can be easily installed. When the first drive member 111 drives the adjustment plate 105 to move in the first direction, the adjustment plate 105 can simultaneously drive the angle detection adjuster 103 and the pressure roller 102 to move in the first direction, so as to realize the adjustment of the relative position of the pressure rollers 102 of the two roller pressing mechanisms 10a in the first direction, so as to adapt to the roller pressing requirements of battery cells 200 of different sizes and to adapt to the roller pressing requirements of the welding area of ​​the battery cells 200 in different directions.

[0038] In some embodiments of the present invention, such as Figure 4 As shown, the roller pressing mechanism 10a may further include a mounting base 104 and an adjusting member 108. The mounting base 104 is rotatably mounted on the adjusting plate 105 about a first axis extending in the vertical direction. The pressure rollers 102 and the angle detection adjuster 103 are both mounted on the mounting base 104. The adjusting member 108 is connected to the mounting base 104 and is used to drive the mounting base 104 to rotate relative to the adjusting plate 105 in order to adjust the relative position between the two pressure rollers 102.

[0039] For example, the pressure roller 102 extends in the vertical direction, the pressure roller 102 is rotatable about its own axis, and the pressure roller 102 is mounted on the mounting base 104. Further, the mounting base 104 is located in a second direction (e.g., Figure 4 One end of the mounting base 104 (in the left-right direction shown in the diagram) is rotatably connected to the adjusting plate 105 so that it can rotate around the first axis. The pressure roller 102 is located at the other end of the mounting base 104 in the second direction. When the adjusting member 108 drives the mounting base 104 to rotate relative to the adjusting plate 105 around the first axis extending in the up-down direction, the pressure roller 102 located at the other end of the mounting base 104 in the second direction will swing in the second direction. At this time, the relative position of the pressure rollers 102 of the two roller pressing mechanisms 10a in the second direction will change. Thus, the relative position of the pressure rollers 102 of the two roller pressing mechanisms 10a can be adjusted, and the roller pressure of the battery cell 200 can be adjusted to meet the roller pressing requirements of battery cells 200 of different sizes.

[0040] In some examples, the adjustment element 108 can be a drive motor.

[0041] In other examples, the adjusting element 108 can be an adjusting knob, which allows for manual adjustment of the angle between the mounting base 104 and the adjusting plate 105 by turning the adjusting knob.

[0042] In some embodiments of the present invention, such as Figure 4As shown, the adjusting plate 105 is provided with a first hole, and the mounting base 104 is provided with a second hole 1041. The first hole and the second hole 1041 are provided correspondingly in the vertical direction. At least one of the first hole and the second hole 1041 extends along an arc with the first axis as the center to form an arc-shaped hole. The mounting base 104 and the adjusting plate 105 are fastened together by fasteners passing through the first hole and the second hole 1041.

[0043] For example, the first hole on the adjusting plate 105 is an arc-shaped hole, and the second hole 1041 on the mounting base 104 is a round hole. Or, the first hole on the adjusting plate 105 is a round hole, and the second hole 1041 on the mounting base 104 is an arc-shaped hole. Or, the first hole on the adjusting plate 105 is an arc-shaped hole, and the second hole 1041 on the mounting base 104 is also an arc-shaped hole.

[0044] When it is necessary to adjust the relative angle between the mounting base 104 and the adjusting plate 105, the fasteners can be loosened to allow the mounting base 104 and the adjusting plate 105 to rotate relative to each other. Then, the adjusting component 108 can be turned to adjust the position of the mounting base 104. After the position of the mounting base 104 is adjusted, the fasteners can be tightened to lock the mounting base 104 and the adjusting plate 105 at the current relative angle. This improves the positional accuracy between the mounting base 104 and the adjusting plate 105, prevents the mounting base 104 from sliding relative to the adjusting plate 105 during the rolling process, and ensures the rolling pressure and rolling accuracy of the battery cell 200.

[0045] In addition, by setting the first hole and / or the second hole 1041 as an arc-shaped hole, and by passing the fastener through the first hole and the second hole 1041, the maximum rotation angle between the mounting base 104 and the adjusting plate 105 can be limited, which can play a limiting role, prevent the mounting base 104 from rotating too much, and prevent the mounting base 104 from interfering with adjacent components.

[0046] In some embodiments of the present invention, such as Figure 4 As shown, there are multiple first holes, which are arranged radially inward and outward along the first axis. There are also multiple second holes 1041, each corresponding one-to-one with a first hole. For example, the number of first holes can be two, three, four, or more, and the number of second holes 1041 can also be two, three, four, or more. This embodiment, by providing multiple first holes and second holes 1041, increases the connection points between the mounting base 104 and the adjusting plate 105, improves the uniformity of force distribution between the mounting base 104 and the adjusting plate 105, reduces stress concentration, and extends the service life of the roller pressing mechanism 10a.

[0047] In some embodiments of the present invention, such as Figure 4As shown, the first driving component 111 is a cylinder. Therefore, the first driving component 111 can smoothly output linear thrust, driving the adjusting plate 105 to move along the second direction, precisely adjusting the relative position of the two pressure rollers 102 in the second direction. This allows the two pressure rollers 102 to precisely fit against the welding areas on opposite sides of the battery cell 200, easily control the pressure of the pressure rollers 102 on the battery cell 200, and also provides a certain buffering performance to avoid damage to the battery cell 200.

[0048] In some embodiments of the present invention, such as Figure 4 As shown, the roller pressing mechanism 10a further includes: a first guide rail 121, which extends along a first direction, and an adjusting plate 105 is slidably disposed on the first guide rail 121. Figure 3 As shown, the adjusting plate 105 is set horizontally and along the second direction (e.g., Figure 4 Extending in the left-right direction (as shown in the diagram), one end of the adjusting plate 105 is connected to the first driving member 111, and the lower surface of the other end of the adjusting plate 105 is provided with a first slider, which is slidably engaged with the first guide rail 121. When the first driving member 111 drives the adjusting plate 105 to move, the adjusting plate 105 can slide along the first guide rail 121. In this embodiment, the first guide rail 121 can guide and limit the movement of the adjusting plate 105 in the first direction, so that the adjusting plate 105 can move smoothly, avoid the adjusting plate 105 from deviating or tilting, and improve the position adjustment accuracy of the adjusting plate 105.

[0049] In some embodiments of the present invention, such as Figure 4 As shown, the roller pressing device 10 further includes a roller pressing drive 112, which is connected to the roller pressing mechanism 10a and is used to drive the roller pressing mechanism 10a along a second direction in the horizontal plane (e.g., Figure 4 The roller 10a moves in the left-right direction (as shown in the diagram) to roll the battery cell 200, with the first direction perpendicular to the second direction. When it is necessary to roll the welding area of ​​the battery cell 200, the angle of the pressure roller 102 and the relative position of the two pressure rollers 102 are first adjusted according to the model and position of the battery cell 200 to confirm that the pressure roller 102 is in the initial position suitable for starting the rolling. Then, the rolling drive 112 can drive the rolling mechanism 10a to move along the second direction to roll the welding area of ​​the battery cell 200 extending along the second direction. This allows for convenient and complete rolling of the welding area along the second direction, improving the rolling quality of the battery cell 200. In this embodiment, when rolling the battery cell 200, the battery cell 200 is fixed, and the rolling mechanism 10a moves under the drive of the rolling drive 112 to realize the rolling operation of the battery cell 200.

[0050] In some embodiments of the present invention, such as Figure 4As shown, the roller pressing drive 112 is a cylinder. Therefore, the roller pressing drive 112 can smoothly output linear thrust to drive the roller pressing mechanism 10a to move along the second direction, so as to precisely control the movement stroke of the roller pressing mechanism 10a in the second direction.

[0051] In some embodiments of the present invention, such as Figure 4 As shown, the rolling device 10 further includes: a first movable plate 106, two rolling mechanisms 10a are both mounted on the first movable plate 106, and a rolling drive 112 is connected to the first movable plate 106 to drive the first movable plate 106 to move along the second direction. For example, the first drive 111 and the first guide rail 121 are both mounted on the first movable plate 106. When the rolling drive 112 drives the first movable plate 106 to move along the second direction, the first movable plate 106 can simultaneously drive the two rolling mechanisms 10a to move along the second direction, thereby causing the two pressure rollers 102 to move simultaneously along the second direction. Thus, by using one rolling drive 112, two pressure rollers 102 can be driven to move simultaneously, achieving synchronous rolling of the welding areas on opposite sides of the battery cell 200 in the first direction, thereby improving rolling efficiency, reducing the number of parts, and making the rolling device 10 more compact.

[0052] In some embodiments of the present invention, such as Figure 4 As shown, the roller pressing device 10 further includes: a second guide rail 122, the second guide rail 122 being along a second direction (e.g., Figure 4 Extending in the left-right direction (as shown), the first movable plate 106 is slidably mounted on the second guide rail 122. Figure 4 As shown, the first moving plate 106 is a horizontal plate, with its length along a first direction. One side of the first moving plate 106 in a second direction is connected to the roller pressing drive 112. The first drive 111 and the first guide rail 121 of the roller pressing mechanism 10a are both fixed to the upper surface of the first moving plate 106. A second slider is provided on the lower surface of the first moving plate 106, and the second slider is slidably fitted onto the second guide rail 122. When the roller pressing drive 112 drives the first moving plate 106 to move, the first moving plate 106 can slide along the second guide rail 122. In this embodiment, the second guide rail 122 can guide and limit the movement of the first moving plate 106 in the second direction, allowing the first moving plate 106 to move smoothly, preventing offset and skew, and improving the position control accuracy of the first moving plate 106.

[0053] In some examples, there are multiple second guide rails 122, which are arranged at intervals along a first direction. The lower surface of the first moving plate 106 is provided with multiple second sliders, and each second guide rail 122 slides in engagement with at least one second slider. This further improves the guiding accuracy and stability of the movement of the first moving plate 106.

[0054] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the rolling device 10 further includes a second movable plate 107 and a moving drive member 113. A first movable plate 106 is movably mounted on the second movable plate 107 along a second direction. The second movable plate 107 is movably mounted on the base 101 along a second direction. The moving drive member 113 is connected to the second movable plate 107 and is used to drive the second movable plate 107 to move along the second direction, thereby adjusting the relative position of the rolling mechanism 10a and the battery cell 200 in the second direction. The moving drive member 113 is used to drive the rolling mechanism 10a closer to or further away from the battery cell 200.

[0055] In some embodiments, such as Figure 4 As shown, the moving drive component 113 is a motor.

[0056] When the moving drive 113 drives the second moving plate 107 to move, the second moving plate 107 can drive the two roller pressing mechanisms 10a to move along the second direction through the first moving plate 106, thereby adjusting the relative position of the roller pressing mechanism 10a and the battery cell 200 in the second direction, so that the roller pressing mechanism 10a can move towards the direction of gradually approaching and gradually moving away from the battery cell 200.

[0057] For example, when it is necessary to transport the battery cell 200 to the rolling device 10, the moving drive 113 can drive the second moving plate 107 to move away from the battery conveying mechanism 20 in the second direction to avoid the rolling mechanism 10a interfering with the transport and positioning of the battery cell 200. After the battery cell 200 is transported to the rolling device 10 and positioned, the moving drive 113 can drive the second moving plate 107 to move so that the rolling mechanism 10a is close to the battery cell 200 and the pressure roller 102 is positioned to prepare to roll the battery cell 200.

[0058] In some embodiments of the present invention, such as Figure 4 As shown, the roller pressing device 10 further includes: a third guide rail 123, which extends along a second direction and is disposed on the base 101, and a second movable plate 107 is movably disposed on the third guide rail 123. Figure 4 and Figure 5As shown, the second movable plate 107 is a horizontally arranged rectangular plate, positioned above the base 101. A moving drive component 113 is located between the second movable plate 107 and the base 101, and connected to the second movable plate 107. The roller pressing drive component 112 and the second guide rail 122 are both fixed to the upper surface of the second movable plate 107. A third slider is provided on the lower surface of the second movable plate 107, slidably engaging with the third guide rail 123. When the moving drive component 113 drives the second movable plate 107 to move, the second movable plate 107 can slide along the third guide rail 123. The third guide rail 123 guides and limits the movement of the second movable plate 107 in the second direction, allowing for smooth movement and preventing offset or skew, thus improving the positional control accuracy of the second movable plate 107.

[0059] In some examples, there are multiple third guide rails 123, which are spaced apart along a first direction. The lower surface of the second moving plate 107 is provided with multiple third sliders, and each third guide rail 123 slides in engagement with at least one third slider. This further improves the guiding accuracy and stability of the movement of the second moving plate 107.

[0060] like Figure 1 and Figure 2 As shown, the battery processing apparatus 100 according to a second aspect embodiment of the present invention includes a rolling device 10 according to the first aspect embodiment of the present invention described above.

[0061] According to the battery processing equipment 100 of the present invention, by providing the roller pressing device 10 of the first aspect embodiment described above, the roller pressing device 10 can automatically adjust the angle and relative position of the two pressing rollers 102 through the angle detection adjuster 103 and the first driving member 111, so that the roller pressing device 10 can be adapted to different types of battery cells 200, improving the applicability of the roller pressing device 10, and can also accurately control the pressure of the pressing rollers 102 on the battery cells 200, effectively avoiding damage or ineffective pressing of the battery cells 200, improving the rolling quality and rolling efficiency of the roller pressing device 10, thereby improving the overall performance of the battery processing equipment 100.

[0062] In some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 9 As shown, the battery processing equipment 100 may further include a battery conveying mechanism 20, which is configured to convey battery cells 200 along a first direction. In some examples, the battery conveying mechanism 20 may be a magnetic levitation conveying mechanism. This can improve the conveying efficiency of the battery cells 200.

[0063] like Figure 1 and Figure 2 As shown, there are multiple roller pressing devices 10, including a first roller pressing device and a second roller pressing device. The first roller pressing device and the second roller pressing device are arranged on opposite sides of the battery conveying mechanism 20 in a second direction, and the first direction is perpendicular to the second direction.

[0064] For example, the number of rolling devices 10 can be two, four, six, eight, or more. A portion of the multiple rolling devices 10 is formed as a first rolling device, and another portion is formed as a second rolling device. The first and second rolling devices are arranged opposite each other on both sides of the battery conveying mechanism 20 in the width direction. When rolling the battery cell 200, the first and second rolling devices can cooperate to jointly roll the battery cell 200. For example, the first rolling device can roll a portion of the welding area of ​​the battery cell 200 along the second direction, and the second rolling device can roll another portion of the welding area of ​​the battery cell 200 along the second direction. This reduces the moving distance of the pressure roller 102 of a single rolling device 10 in the second direction, improves the stability and reliability of rolling, shortens the rolling time, and increases the rolling efficiency of the battery cell 200.

[0065] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, there are multiple first rolling devices, which are arranged at intervals in a first direction. There are also multiple second rolling devices, each corresponding to one of the first rolling devices and facing each other in a second direction. In other words, the first and second rolling devices are arranged in pairs. This allows the first and second rolling devices to simultaneously roll the same pair of welding areas of the battery cell 200, improving the rolling efficiency of a single battery cell 200. Furthermore, the multiple first and second rolling devices can simultaneously roll multiple battery cells 200, improving the overall processing efficiency of the battery processing equipment 100.

[0066] In addition, by simultaneously pressing the welding area of ​​the same battery cell 200 by the first and second roller pressing devices, the battery cell 200 can be subjected to symmetrical force in the second direction, thus preventing the battery cell 200 from shifting in the second direction.

[0067] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the battery processing equipment 100 may further include a first fixing mechanism 30, which is configured to fix the battery cell 200 in the vertical direction. In this embodiment, by providing the first fixing mechanism 30, the position of the battery cell 200 can be restricted in the vertical direction, preventing the battery cell 200 from shifting vertically during rolling, ensuring that the rolling pressure of the rolling device 10 can act on the welding area, and guaranteeing the rolling effect and efficiency.

[0068] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the battery processing equipment 100 may further include a second fixing mechanism 40, which is configured to clamp and fix the battery cell 200 in a second direction. In this embodiment, by providing the second fixing mechanism 40, the second fixing mechanism 40 can limit the position of the battery cell 200 in the second direction, restrict the lateral displacement of the battery cell 200 along the second direction, prevent the battery cell 200 from shifting when the rolling device 10 rolls the battery cell 200, and ensure that the rolling path of the rolling device 10 conforms to a preset trajectory.

[0069] Furthermore, by simultaneously setting the first fixing mechanism 30 and the second fixing mechanism 40, the battery cell 200 can be fixed in both the vertical and horizontal directions and the second direction, thereby improving the positioning accuracy of the battery cell 200 and avoiding uneven rolling or damage to the casing of the battery cell 200 due to shaking of the battery cell 200 during the rolling process.

[0070] In some embodiments of the present invention, such as Figure 1 and Figure 8 As shown, the first fixing mechanism 30 includes: a first bracket 31, a first positioning block 32 and a first positioning drive member 33. The first positioning block 32 is movably disposed on the first bracket 31 in the vertical direction. The first positioning block 32 is used to press against the upper surface of the battery cell 200. The first positioning drive member 33 is connected to the first positioning block 32 and is used to drive the first positioning block 32 to move up and down.

[0071] For example, the first positioning block 32 is movable in the vertical direction between the first initial position and the first positioning position. In the first initial position, the first positioning block 32 is away from the battery cell 200 in the vertical direction. In the first positioning position, the lower surface of the first positioning block 32 abuts against the upper surface of the battery cell 200.

[0072] In some examples, the first positioning drive 33 is a cylinder.

[0073] When the battery cell 200 needs to be conveyed to the rolling device 10, the first positioning drive 33 drives the first positioning block 32 to move in the vertical direction to the first initial position to avoid the first positioning block 32 affecting the battery conveying mechanism 20 in conveying the battery cell 200. When the battery cell 200 reaches the rolling station, the first positioning drive 33 drives the first positioning block 32 to move downward toward the first positioning position, so that the first positioning block 32 gradually approaches, adheres to and presses against the upper surface of the battery cell 200. Finally, the first positioning drive 33 maintains the pressure so that the first positioning block 32 and the battery cell 200 are kept in a pressed state, thereby fixing and limiting the battery cell 200 in the vertical direction. After the battery cell 200 is rolled, the first positioning drive 33 drives the first positioning block 32 to move upward to the first initial position to reset. At this time, the battery cell 200 can be conveyed out of the rolling device 10 by the battery conveying mechanism 20, or the battery cell 200 can be clamped by the clamping device and the position of the battery cell 200 can be rotated and adjusted so that the rolling device 10 can roll the welding area of ​​the battery cell 200 in another direction.

[0074] In this embodiment, by setting a first positioning block 32, the first positioning block 32 can cooperate with the lower support structure of the battery cell 200 to limit the battery cell 200 in the vertical direction, thereby improving the stability of the limit on the battery cell 200. By setting a first positioning drive 33 to drive the first positioning block 32 to move, the first fixing mechanism 30 can be adapted to battery cells 200 of different heights and sizes, thereby improving the applicability of the first fixing mechanism 30.

[0075] In some examples, the lower surface of the first positioning block 32 may be provided with a flexible pad, and the first positioning block 32 can abut against the battery cell 200 through the flexible pad. This can avoid hard contact between the first positioning block 32 and the battery cell 200 and avoid damage to the casing of the battery cell 200.

[0076] In some embodiments of the present invention, such as Figure 8 As shown, the first fixing mechanism 30 further includes: a first slide rail 34, which is disposed on the first bracket 31 and extends in the vertical direction, and a first positioning block 32 is slidably disposed on the first slide rail 34. The first slide rail 34 can guide the movement of the first positioning block 32 in the vertical direction, so that the first positioning block 32 can slide smoothly and avoid the first positioning block 32 from tilting or shifting.

[0077] like Figure 8As shown, the first bracket 31 extends vertically, and the first slide rail 34 is disposed on the side of the first bracket 31 facing the battery delivery mechanism 20 in the second direction. The first fixing mechanism 30 also includes a first movable frame 35, which is arranged on the side of the first bracket 31 facing the battery delivery mechanism 20. The first movable frame 35 is slidably connected to the first slide rail 34 via a first sliding block. A first positioning block 32 is fixed to the lower end of the first movable frame 35. For example, the first positioning block 32 can be fixed to the lower side of the first movable frame 35 by fasteners. The first movable frame 35 may include an L-shaped frame body and a reinforcing plate connected to the frame body.

[0078] In some embodiments of the present invention, such as Figure 1 , Figure 6 and Figure 7 As shown, the second fixing mechanism 40 includes a first clamping component 401 and a second clamping component 402. The first clamping component 401 and the second clamping component 402 are respectively arranged on opposite sides of the battery conveying mechanism 20 in the second direction. The first clamping component 401 and the second clamping component 402 cooperate with each other to clamp the battery cell 200 in the second direction.

[0079] like Figure 1 , Figure 6 and Figure 7 As shown, both the first clamping assembly 401 and the second clamping assembly 402 include: a second bracket 41, a second positioning block 42, and a second positioning drive member 43. The second positioning block 42 is movably disposed on the second bracket 41 along a second direction. The second positioning drive member 43 is connected to the second positioning block 42 and is used to drive the second positioning block 42 to move along the second direction. The second positioning block 42 of the first clamping assembly 401 and the second positioning block 42 of the second clamping assembly 402 cooperate with each other to clamp the battery cell 200.

[0080] For example, the second positioning block 42 is movable along the second direction between the second initial position and the second positioning position. In the second initial position, the second positioning block 42 is away from the battery cell 200 in the second direction. In the second positioning position, the end face of the second positioning block 42 facing the battery cell 200 abuts against the end face of the battery cell 200 in the second direction.

[0081] In some examples, the second positioning drive 43 is a motor.

[0082] When it is necessary to transport the battery cell 200 to the rolling device 10, the second positioning drive 43 drives the second positioning block 42 to move along the second direction to the second initial position to avoid the second positioning block 42 affecting the battery conveying mechanism 20 in transporting the battery cell 200. When the battery cell 200 reaches the rolling station, the second positioning drive 43 drives the second positioning block 42 to move toward the second positioning position close to the battery cell 200, so that the second positioning block 42 gradually approaches, adheres to and presses against the side of the battery cell 200. Finally, the second positioning drive 43 maintains the pressure so that the second positioning block 42 and the battery cell 200 are kept in a pressed state, thereby fixing and limiting the battery cell 200 in the second direction. After the battery cell 200 is rolled, the second positioning drive 43 drives the second positioning block 42 away from the battery cell 200 in the second direction and moves to the second initial position to achieve reset. At this time, the battery cell 200 can be conveyed out of the rolling device 10 by the battery conveying mechanism 20, or the battery cell 200 can be clamped by the clamping device and the position of the battery cell 200 can be adjusted by rotation so that the rolling device 10 can roll the welding area of ​​the battery cell 200 in another direction.

[0083] In this embodiment, by setting a second positioning block 42, the two second positioning blocks 42 of the first clamping component 401 and the second clamping component 402 can cooperate with the battery cell 200 to limit the battery cell 200 in the second direction, thereby improving the stability of the battery cell 200 limit. By setting a second positioning drive member 43 to drive the second positioning block 42 to move, the second fixing mechanism 40 can be adapted to battery cells 200 with different widths, thereby improving the applicability of the second fixing mechanism 40.

[0084] In some embodiments of the present invention, such as Figure 1 , Figure 6 and Figure 7 As shown, the first clamping assembly 401 and the second clamping assembly 402 further include: a second slide rail 44, which is disposed on the second bracket 41 and extends along the second direction, and a second positioning block 42 is slidably disposed on the second slide rail 44. The second slide rail 44 can guide the movement of the second positioning block 42 in the second direction, so that the second positioning block 42 can slide smoothly and avoid the second positioning block 42 from tilting or shifting.

[0085] like Figure 6 and Figure 7As shown, the second bracket 41 extends vertically, and the second positioning drive 43 is located on the side of the second bracket 41 opposite to the battery conveying mechanism 20. The second positioning drive 43 is a drive motor. The second slide rail 44 is located on the top of the second bracket 41. There are multiple second slide rails 44, which extend along a second direction and are spaced apart in the first direction. The first clamping assembly 401 and the second clamping assembly 402 may also include a second movable frame 47. The second movable frame 47 extends vertically and is arranged above the second bracket 41. The second movable frame 47 is slidably connected to the second slide rail 44 via a second sliding block. The second positioning block 42 is fixed to the side of the second movable frame 47 facing the battery conveying mechanism 20 in the second direction and is arranged on the upper part of the second movable frame 47.

[0086] In some embodiments of the present invention, such as Figure 1 , Figure 6 and Figure 7 As shown, the surface of the second positioning block 42 facing the battery conveying mechanism 20 in the second direction is the first surface. The first surface of the second positioning block 42 of the first clamping assembly 401 is provided with two limiting blocks 46 arranged at intervals in the first direction. The two limiting blocks 46 are adapted to limit the battery cell 200. Thus, the two limiting blocks 46 can limit the battery cell 200 in the first direction, restrict the battery cell 200 from displacing in the first direction, and ensure the efficiency and rolling quality of the rolling device 10.

[0087] In some embodiments of the present invention, such as Figure 1 , Figure 6 and Figure 7 As shown, the first surface of the second positioning block 42 of the second clamping assembly 402 is provided with a buffer pad 45. The buffer pad 45 can buffer and prevent collisions when the second positioning block 42 positions the battery cell 200, avoiding hard contact between the second positioning block 42 and the battery cell 200 and preventing damage to the casing of the battery cell 200. In some examples, the buffer pad 45 is urethane.

[0088] In some embodiments of the present invention, such as Figure 1 As shown, the battery processing equipment 100 further includes a drive mechanism connected to the roller pressing device 10, used to drive the roller pressing device 10 to move along a first direction. Thus, the position of the roller pressing device 10 can be adjusted to achieve roller pressing of battery cells 200 at different positions along the first direction.

[0089] The following describes the rolling process of the battery processing equipment 100 on the battery cell 200 according to an embodiment of the present invention. The battery processing equipment 100 is mainly used to roll the two long welding edges 201 and two short welding edges 202 of the battery cell 200 to make the solder of the battery cell 200 flat.

[0090] First, the battery conveying mechanism 20 conveys the battery cells 200 between the first and second roller pressing devices for processing. The battery conveying mechanism 20 can convey multiple battery cells 200 as a battery pack, with each battery pack including multiple battery cells 200 spaced apart along the conveying direction. For example, each battery pack may include two, three, four, or five or more battery cells 200.

[0091] Second, the second positioning drive 43 is activated. Under the guidance of the second slide rail 44, the second positioning drive 43 pushes the second positioning blocks 42 located on both sides of the battery cell 200 to clamp and fix the battery cell 200 in the middle. The first positioning drive 33 is activated. Under the guidance of the first slide rail 34, the first positioning drive 33 pushes the first positioning block 32 downward to fix the upper surface of the cover of the battery cell 200.

[0092] Third, the pressure roller 102 is adjusted to the required rolling angle by the angle detection adjuster 103 and the first drive member 111 to avoid the phenomenon of moving away from the rolling surface during the later rolling process.

[0093] Fourth, the moving drive 113 is activated. Guided by the third guide rail 123, the moving drive 113 pushes the pressure rollers 102 of the two rolling mechanisms 10a close to the two long welded edges 201 of the battery cell 200 via the second moving plate 107. The rolling drive 112 is activated. Guided by the second guide rail 122, the rolling drive 112 pushes the pressure rollers 102 on both sides of the battery cell 200 to roll the long welded edges 201 of the battery cell 200 until the pressure rollers 102 of the first and second rolling devices meet at the middle position of the long welded edges 201 of the battery cell 200. Then the rolling drive 112 is activated. Under the action of the second guide rail 122, the rolling drive 112 pulls the two rolling mechanisms 10a back to their initial state (i.e., close to the battery cell 200), and the rolling is completed.

[0094] Fifth, the first fixing mechanism 30 and the second fixing mechanism 40 release the battery cell 200, the gripping device (e.g., a robotic arm) grips the battery cell 200, rotates the battery cell 200 by 90 degrees, and fixes the battery cell 200 again through the first fixing mechanism 30 and the second fixing mechanism 40. Then, the two short welded edges 202 of the battery cell 200 are rolled, wherein the rolling process of the short welded edges 202 is the same as the rolling process of the long welded edges 201.

[0095] Sixth, after confirming that the battery cell 200 has completed rolling, the drive mechanism drives the rolling device 10 to move, so that the rolling device 10 moves to the next battery cell 200 in the battery pack, and repeats the above steps until all the battery cells 200 in the battery pack have completed rolling.
