Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a shaping device, a shaping method, and a battery production line. Background Technology

[0002] Before shaping, most bare battery cells undergo a winding process. During this process, the electrodes and separators in the bare cells retain some residual tension that cannot be released. When the blanking needle is pulled out, the separator will rebound significantly, causing the inner electrode to slip and resulting in abnormal gaps in the inner ring. Summary of the Invention

[0003] The main objective of this invention is to provide a shaping device, a shaping method, and a battery production line, which aims to improve the problem of abnormal gaps between the layers of the inner ring of a bare battery cell.

[0004] To achieve the above objectives, this invention proposes a shaping device, a shaping method, and a battery production line. The shaping device is used to shape bare battery cells, each having two openings arranged opposite each other along a first direction. The bare battery cell includes a first region and a second region arranged along the first direction. The shaping device includes a support platform, a first clamping assembly, a second clamping assembly, a first pressure plate, and a second pressure plate. The support platform is used to hold the bare battery cell. The first clamping assembly is arranged opposite to the first region and clamps the inner and outer walls of the first region. The second clamping assembly is arranged opposite to the second region and clamps the inner and outer walls of the second region. The first pressure plate is arranged opposite to the side of the first region facing away from the support platform. The second pressure plate is arranged opposite to the side of the second region facing away from the support platform.

[0005] The technical solution of this invention involves setting a first clamping component opposite to a first region and clamping the inner and outer walls of the first region, setting a second clamping component opposite to a second region and clamping the inner and outer walls of the second region, and setting a first pressure plate opposite to the side of the first region away from the support platform, and setting a second pressure plate opposite to the side of the second region away from the support platform. This allows the first clamping component to be pulled out of the first region and the first region to be pressed down and shaped by the first pressure plate. At this time, since the second clamping component is in the state of clamping the second region, the risk of abnormal gap in the inner ring of the first region caused by the rebound of the inner ring electrode and diaphragm can be reduced.

[0006] When the first pressure plate presses the first region tightly, and the inner ring of the first region is pressed against the wall surface near the support platform and the wall surface away from the support platform, the second clamping assembly is pulled out from the inner ring of the second region. At this time, since the first region is pressed tightly by the first pressure plate, the risk of abnormal gaps in the inner ring of the second region caused by the rebound of the electrode and separator of the inner ring of the bare cell can also be reduced. The second pressure plate can stably press the second region tightly, and make it less likely for gaps to appear at the corners of the inner ring of the second region, thereby improving the problem of abnormal gaps between the layers of the inner ring of the bare cell as a whole.

[0007] In one embodiment, a portion of the projection of the first clamping assembly onto the support platform falls within the projection of the second pressure plate onto the support platform.

[0008] With this configuration, when the first pressure plate presses down and shapes the first region, and the second clamping assembly is still clamping the inner and outer walls of the second region, the transition area between the first and second regions is a rounded transition, which reduces the risk that the angle between the first and second regions is too obvious and the bare cell will be deformed to a large extent.

[0009] In one embodiment, the size of the second pressure plate is larger than the size of the first pressure plate along the first direction.

[0010] With this setup, when the first pressure plate is driven to press down and shape the first region, and then the second pressure plate is driven to press down and shape the second region, it can be ensured that the wall surface near the support platform and the wall surface away from the support platform in the inner ring of the first region are more likely to fit together. This ensures that when the second clamping assembly is subsequently pulled out of the bare cell, the rebound of the electrode and separator of the bare cell is better restricted, thereby reducing the problem of abnormal gaps in the inner ring of the bare cell.

[0011] In one embodiment, the second clamping assembly includes an inner clamping member and an outer clamping member. The inner clamping member clamps the inner wall of the second region, and the end face of the inner clamping member near the first clamping assembly is inclined toward the second pressure plate along the first direction. The outer clamping member clamps the outer wall of the second region.

[0012] With this configuration, when the second clamping component clamps the second region and the first pressure plate presses down on the first region, the angle of the side of the first region closest to the second region is less than 90°, thereby reducing the risk of the bare cell being crushed by the second clamping component.

[0013] In one embodiment, the first clamping assembly includes a clamping body and a connecting portion, and the second clamping assembly is arranged with the clamping body in a first direction; one end of the connecting portion is connected to the clamping body, and the other end extends toward the first direction, and the second clamping assembly is clamped between the connecting portion and the bare battery cell.

[0014] With this configuration, the connecting part can be connected to the driving component on the side closer to the second clamping component, so that the driving component that drives the first clamping component to extract the bare battery cell and the driving component that drives the second clamping component to extract the bare battery cell can be distributed on the same side of the bare battery cell, thereby reducing the space occupied by the shaping equipment.

[0015] In one embodiment, the bare cell further includes a third region, which is located on the side of the first region away from the second region; the shaping device further includes a third clamping assembly and a third pressure plate, the third clamping assembly is located on the side of the first clamping assembly away from the second clamping assembly, and clamps the inner wall and outer wall of the third region; the third pressure plate is located on the side of the first pressure plate away from the second pressure plate, and is disposed opposite to the side of the third region away from the support platform.

[0016] This configuration results in a larger number of partitions for the bare cell, ensuring that the pressure plate for each area can be pressed into place after being pressed down. This further ensures that the inner ring of each bare cell has a wall surface close to the support platform and a wall surface away from the support platform, thereby further reducing the risk of abnormal gaps in the inner ring of the bare cell.

[0017] The present invention also proposes a shaping method based on the above-mentioned shaping equipment, the shaping method comprising:

[0018] Control the first clamping assembly to release the bare battery cell and pull it out of the bare battery cell;

[0019] Control the first pressure plate to move towards the support platform;

[0020] Control the second clamping assembly to release the bare battery cell and pull it out of the bare battery cell;

[0021] Control the second pressure plate to move towards the support platform.

[0022] The shaping method of the present invention first controls the first clamping component to release the bare cell and pull it out of the bare cell, while the second clamping component still holds the bare cell. This makes it so that when the first clamping component is pulled out of the bare cell, the electrode and separator of the first region of the bare cell are hindered from rebounding because the second clamping component is holding the second region. As a result, when the first pressure plate is controlled to move towards the support platform to press down on the first region, the inner ring of the first region is less likely to have abnormal gaps due to the rebound of the electrode and separator.

[0023] By controlling the first pressure plate to move closer to the support platform and then controlling the second clamping assembly to release the bare cell, the rebound of the electrode and separator corresponding to the second region is hindered by the first pressure plate pressing the first region when the second clamping assembly releases the bare cell and pulls it out of the bare cell. Therefore, when the second pressure plate moves closer to the support platform to press and shape the second region, the second region is less likely to have abnormal gaps due to the rebound of the electrode and separator. This allows both the first and second regions to be compacted, greatly reducing the risk of abnormal gaps in the first and second regions.

[0024] In one embodiment, the step of controlling the first clamping assembly to release the bare battery cell and extract it from the bare battery cell further includes the following steps before:

[0025] Control both the first pressure plate and the second pressure plate to press down a preset distance.

[0026] This setup enables pre-shaping of the bare battery cell, making it easier for the first and second pressure plates to press the bare battery cell firmly, so that the surface of the bare battery cell's inner wall near the support platform is in close contact with the surface of the bare battery cell's inner wall away from the support platform.

[0027] In one embodiment, the bare cell further includes a third region, the third region being disposed on the side of the first region away from the second region; the shaping device further includes a third clamping assembly and a third pressure plate, the third clamping assembly being disposed on the side of the first clamping assembly away from the second clamping assembly, and clamping the inner and outer walls of the third region; the third pressure plate being disposed on the side of the first pressure plate away from the second pressure plate, and opposite to the side of the third region away from the support platform; after the step of controlling the first pressure plate to move toward the support platform, the device further includes:

[0028] Control the third clamping assembly to release the bare battery cell and pull it out of the bare battery cell;

[0029] Control the third pressure plate to move towards the support platform, and make the third pressure plate flush with the first pressure plate.

[0030] This configuration divides the bare cell into more regions, and each region is individually pressed and shaped. This allows each pressure plate to shape a smaller region, thereby improving the shaping quality of each region and further reducing the risk of abnormal gaps in the inner ring of the bare cell.

[0031] In one embodiment, the step of controlling the second clamping assembly to release the bare battery cell and withdraw it from the bare battery cell is performed simultaneously with the step of controlling the third clamping assembly to release the bare battery cell and withdraw it from the bare battery cell;

[0032] The steps of controlling the second pressure plate to move closer to the support platform and the steps of controlling the third pressure plate to move closer to the support platform are performed simultaneously.

[0033] This setup can improve the efficiency of plastic surgery equipment.

[0034] In one embodiment, the step of controlling the second clamping assembly to release the bare battery cell and extract it from the bare battery cell specifically includes:

[0035] Control the second clamping assembly to release the bare battery cell;

[0036] Control the second clamping assembly to be pulled out of the bare cell along the first direction;

[0037] The step of controlling the third clamping assembly to release the bare battery cell and extract it from the bare battery cell specifically includes:

[0038] The third clamping assembly is controlled to release the bare battery cell;

[0039] Control the third clamping assembly to be pulled out of the bare cell in a direction opposite to the first direction.

[0040] This design further reduces the risk of interference between the second and third clamping components when they are simultaneously withdrawn. Additionally, it improves shaping efficiency.

[0041] The present invention also proposes a battery production line, including the above-mentioned shaping equipment. Attached Figure Description

If the specific posture changes, the directional indicators will also change accordingly.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0064] The battery structure mainly consists of a casing and bare cells housed within the casing. The bare cell comprises alternating layers of electrodes and separators. The assembly formed by the electrodes and separators undergoes a winding process, followed by a shaping process to shaped the bare cell into a square or other desired shape. During the winding process, the electrodes and separators are wound onto the winding needles, and both retain residual tension that cannot be released. When the material is withdrawn from the winding needles, the separator and electrodes exhibit some springback due to this residual tension. However, because of the significant difference in Young's modulus between the separator and the electrodes, the separator experiences substantial springback, causing the inner electrode layers to slip and resulting in abnormal gaps between the layers at the corners of the inner ring of the bare cell.

[0065] To address the issue of abnormal gaps between layers within the inner ring of bare battery cells in related technologies, this invention proposes a shaping device.

[0066] Please refer to the reference. Figures 1 to 7 In one embodiment of the present invention, the shaping device 200 is used to shape a bare battery cell 100. The bare battery cell 100 has two openings 101, which are arranged opposite to each other along a first direction. The bare battery cell 100 includes a first region 110 and a second region 120 arranged along the first direction. The shaping device 200 includes a support platform 210, a first clamping assembly 220, a second clamping assembly 230, a first pressure plate 250, and a second pressure plate 260. The support platform 210 is used to place the bare battery cell 100. The first clamping assembly 220 is arranged opposite to the first region 110 and clamps the inner and outer walls of the first region 110. The second clamping assembly 230 is arranged opposite to the second region 120 and clamps the inner and outer walls of the second region 120. The first pressure plate 250 is arranged opposite to the side of the first region 110 away from the support platform 210. The second pressure plate 260 is arranged opposite to the side of the second region 120 away from the support platform 210.

[0067] After the bare battery cell 100 is wound into a cylindrical shape, both ends of the cylindrical bare battery cell 100 have openings 101, and the two openings 101 are arranged opposite each other along a first direction, that is, the first direction refers to the axial direction of the cylindrical shape. The bare battery cell 100 has a first region 110 and a second region 120 arranged along the first direction, that is, the first region 110 and the second region 120 are arranged along the axial direction of the cylindrical shape. The first region 110 and the second region 120 can be of equal size, or the area of ​​the first region 110 can be larger than the area of ​​the second region 120, or the area of ​​the second region 120 can be larger than the area of ​​the first region 110.

[0068] The support platform 210 refers to the component used to support the bare battery cell 100 during the shaping process. The support platform 210 can be a flat plate or a groove-shaped structure, as long as it can achieve the effect of supporting the bare battery cell 100.

[0069] The first clamping assembly 220 refers to the assembly used to clamp the first region 110. The bare cell 100 has two openings 101. It is understood that there can be two sets of first clamping assemblies 220, each clamping the inner and outer walls of the first region 110 of the bare cell 100, with the two first clamping assemblies 220 located on opposite sides of the axis of the bare cell 100. Alternatively, one clamping assembly clamps opposite sides of the inner wall of the first region 110 of the bare cell 100, and the other clamping assembly clamps opposite sides of the outer wall of the first region 110 of the bare cell 100. Of course, in other examples, the first clamping assembly 220 can also be provided in three or more sets. Alternatively, the first clamping assembly 220 may include at least two clamping parts, each clamping opposite sides of the first region 110. The first clamping assembly 220 may include two clamping parts disposed opposite to each other. The clamping parts may be clamping pins, clamping rods, or clamping plates, etc. Both clamping parts are connected to a driving unit, which can drive the two clamping parts to move closer or further apart. It should be noted that clamping assemblies are common knowledge in the art, therefore the detailed structure of the driving unit will not be described in detail.

[0070] The second clamping assembly 230 refers to the assembly used to clamp the second region 120. The bare cell 100 has two openings 101. It is understood that there can be two sets of second clamping assemblies 230, each clamping the inner and outer walls of the second region 120 of the bare cell 100, with the two clamping assemblies 230 located on opposite sides of the axis of the bare cell 100. Alternatively, one clamping assembly clamps opposite sides of the second inner wall of the bare cell 100, and the other clamping assembly clamps opposite sides of the outer wall of the second region 120. Of course, in other examples, the second clamping assembly 230 can also be provided in three or more sets. Alternatively, the second clamping assembly 230 may include at least two clamping portions, each clamping opposite sides of the second region 120. The second clamping assembly 230 may include two clamping parts disposed opposite to each other. The clamping parts may be clamping pins, clamping rods, or clamping plates, etc. Both clamping parts are connected to the driving part, which can drive the two clamping parts to move closer or further apart. It should be noted that clamping assemblies are common knowledge in the art, so the detailed structure of the driving part will not be described in detail.

[0071] The first pressure plate 250 refers to the plate structure disposed on the side of the first region 110 of the bare battery cell 100 away from the support platform 210. The first pressure plate 250 is used to press down on the first region 110, thereby shaping the first region 110. It is understood that the shaping device 200 in this invention may also include a first lifting mechanism for driving the first pressure plate 250 to move toward or away from the support platform 210, and the first lifting mechanism is pulsatorically connected to the first pressure plate 250. The lifting mechanism may be a linear motor, a lead screw and nut assembly, a gear and rack assembly, or a cylinder, etc.

[0072] The second pressure plate 260 refers to the plate structure located on the side of the second region 120 of the bare battery cell 100 facing away from the support platform 210. The second pressure plate 260 is used to press down on the second region 120, thereby shaping the second region 120. It is understood that the shaping device 200 in this invention may also include a second lifting mechanism for driving the second pressure plate 260 to move towards or away from the support platform 210, and the second lifting mechanism is connected to the second pressure plate 260 in a transmission manner. The lifting mechanism may be a linear motor, a lead screw and nut assembly, a gear and rack assembly, or a cylinder, etc.

[0073] The dimensions of the first pressure plate 250 and the second pressure plate 260 may be the same or different. Along the first direction, the projected dimension of the first pressure plate 250 on the support table 210 may be the same as or different from the projected dimension of the first clamping assembly 220 on the support table 210. Similarly, along the first direction, the projected dimension of the second pressure plate 260 on the support table 210 may be the same as or different from the projected dimension of the second clamping assembly 230 on the support table 210.

[0074] During the shaping of the bare battery cell 100, the first pressure plate 250 and the second pressure plate 260 sequentially press down and shape the first region 110 and the second region 120, respectively. Specifically, the first pressure plate 250 can be driven to press down and shape the first region 110 first, and then the second pressure plate 260 can be driven to press down and shape the second region 120; or the second pressure plate 260 can be driven to press down and shape the second region 120 first, and then the first pressure plate 250 can be driven to press down and shape the first region 110. For example, let's take the scheme where the first pressure plate 250 first presses down and shapes the first region 110, and then the second pressure plate 260 presses down and shapes the second region 120 as an example: When the first pressure plate 250 presses down and shapes the first region 110, the first clamping component 220 is pulled out from the bare cell 100 in advance, while the second clamping component 230 still clamps the second region 120. Therefore, the risk of abnormal gap in the inner ring of the bare cell 100 caused by the rebound of the electrode and separator of the first region 110 when the first clamping component 220 is pulled out from the bare cell 100 can be reduced. As a result, the first pressure plate 250 can press down and shape the first region 110 on the basis of the second clamping component 230 supporting the bare cell 100, so that the upper and lower walls of the inner ring of the first region 110 are tightly attached. For example, the first region 110 can be flattened into a state without opening 101, so that the first region 110 is less likely to have abnormal gap. Next, keeping the first pressure plate 250 in its current state, the second clamping assembly 230 is pulled out from the bare cell 100. The second pressure plate 260 presses down on the second region 120 to shape it. Since the first pressure plate 250 has already pressed the first region 110 firmly, the risk of abnormal gaps caused by the rebound of the electrode and separator of the bare cell 100 when the second clamping assembly 230 is removed from the bare cell 100 can be reduced. When the second pressure plate 260 presses down on the second region 120 to shape it, the upper and lower inner walls of the inner ring of the second region 120 can be made to fit tightly. For example, the second region 120 can be flattened to a state without openings 101, so that the second region 120 is also less likely to have abnormal gaps.

[0075] The technical solution of the present invention is achieved by setting the first clamping component 220 opposite to the first region 110 and clamping the inner and outer walls of the first region 110, setting the second clamping component 230 opposite to the second region 120 and clamping the inner and outer walls of the second region 120, setting the first pressure plate 250 opposite to the side of the first region 110 away from the support platform 210, and setting the second pressure plate 260 opposite to the side of the second region 120 away from the support platform 210. This allows the first clamping component 220 to be pulled out from the first region 110 and the first pressure plate 250 to press down and shape the first region 110. At this time, since the second clamping component 230 is in the state of clamping the second region 120, the risk of abnormal gap in the inner ring of the first region 110 caused by the rebound of the electrode and diaphragm of the inner ring can be reduced. When the first pressure plate 250 presses the first region 110 tightly, and the inner ring of the first region 110 with the walls near the support platform 210 and away from the support platform 210 pressed together, the second clamping assembly 230 is pulled out from the inner ring of the second region 120. At this time, since the first region 110 is pressed by the first pressure plate 250, the risk of abnormal gaps in the inner ring of the second region 120 caused by the rebound of the electrode and separator of the inner ring of the bare cell 100 can also be reduced. The second pressure plate 260 can stably press the second region 120, and make it less likely for gaps to appear at the corners of the inner ring of the second region 120, thereby improving the problem of abnormal gaps between the layers of the inner ring of the bare cell 100 as a whole.

[0076] Please refer to the reference. Figures 3 to 5 In some embodiments of the present invention, a portion of the projection of the first clamping assembly 220 on the support platform 210 falls within the projection of the second pressure plate 260 on the support platform 210.

[0077] By placing a portion of the projection of the first clamping assembly 220 on the support platform 210 into the projection of the second pressure plate 260 on the support platform 210, when the first pressure plate 250 presses down and shapes the first region 110, and the second clamping assembly 230 is still clamping the inner and outer walls of the second region 120, the transition area between the first region 110 and the second region 120 is a rounded transition, reducing the risk that the angle between the first region 110 and the second region 120 is too obvious and the bare cell 100 will be deformed to a large extent.

[0078] Please refer to the reference. Figures 3 to 7 In some embodiments of the present invention, the size of the second pressure plate 260 is larger than the size of the first pressure plate 250 along the first direction.

[0079] Along the first direction, the size of the second pressure plate 260 is larger than that of the first pressure plate 250. When the first pressure plate 250 is driven to press down and shape the first region 110, and then the second pressure plate 260 is driven to press down and shape the second region 120, it can be ensured that the wall surface near the support platform 210 and the wall surface away from the support platform 210 in the inner ring of the first region 110 are more likely to fit together. This ensures that when the second clamping assembly 230 is subsequently pulled out from the bare cell 100, the rebound of the electrode and separator of the bare cell 100 is better restricted, thereby reducing the problem of abnormal gaps in the inner ring of the bare cell 100.

[0080] Please refer to the reference. Figures 3 to 8 In some embodiments of the present invention, the second clamping assembly 230 includes an inner clamping member 230a and an outer clamping member 230b. The inner clamping member 230a clamps the inner wall of the second region 120, and the end face of the inner clamping member 230a near the first clamping assembly 220 is inclined in the direction of the second pressure plate 260 along the first direction. The outer clamping member 230b clamps the outer wall of the second region 120.

[0081] The inner clamping member 230a of the second clamping assembly 230 can be a clamping rod, a clamping needle, or a clamping plate, etc. The outer clamping member 230b can also be a clamping rod, a clamping needle, or a clamping plate, etc.

[0082] By tilting the end face of the inner clamping member 230a near the first clamping assembly 220 toward the second pressure plate 260 in the first direction, when the second clamping assembly 230 clamps the second region 120 and the first pressure plate 250 presses down on the first region 110, the angle of the side of the first region 110 near the second region 120 is less than 90°, thereby reducing the risk of the bare cell 100 being crushed by the second clamping assembly 230.

[0083] Please refer to the reference. Figures 3 to 8 In some embodiments of the present invention, the first clamping component 220 includes a clamping body 221 and a connecting portion 222, and the second clamping component 230 is arranged with the clamping body 221 in a first direction; one end of the connecting portion 222 is connected to the clamping body 221, and the other end extends in the first direction, and the second clamping component 230 is clamped between the connecting portion 222 and the bare battery cell 100.

[0084] The clamping body 221 may include an inner clamping portion and an outer clamping portion. The inner clamping portion may be a clamping rod, a clamping needle, or a clamping plate, etc., and the outer clamping portion may also be a clamping rod, a clamping needle, or a clamping plate, etc. If one inner clamping portion and an adjacent outer clamping portion form a clamping body 221, then when the first clamping assembly 220 is withdrawn from the bare battery cell 100, the clamping restrictions on at least one side of the inner and outer rings of the bare battery cell 100 can be released respectively. Alternatively, the clamping body 221 of a first clamping assembly 220 may include two inner clamping portions, which may respectively abut against the opposite inner wall surfaces of the bare battery cell 100; or a first clamping assembly 220 may include two outer clamping portions, which may respectively clamp the opposite outer wall surfaces of the bare battery cell 100.

[0085] The connecting part 222 refers to the component in the first clamping assembly 220 used to connect the driving member. One end of the connecting part 222 is connected to the main body of the clamping plate. The two can be connected by snap-fit, welding, screw connection or other means, as long as the stability of the connection can be guaranteed. The other end of the connecting part 222 extends in the first direction, and the second clamping assembly 230 is clamped between the connecting part 222 and the bare battery cell 100, so that when the connecting part 222 extends in the first direction, it can avoid interference with the second clamping assembly 230 after installation.

[0086] By including a clamping body 221 and a connecting part 222 in the first clamping assembly 220, and arranging the second clamping assembly 230 and the clamping body 221 in a first direction, with one end of the connecting part 222 connected to the clamping body 221 and the other end extending in the first direction, the connecting part 222 can be connected to the driving member on the side close to the second clamping assembly 230. This allows the driving member that drives the first clamping assembly 220 to extract the bare battery cell 100 and the driving member that drives the second clamping assembly 230 to extract the bare battery cell 100 to be distributed on the same side of the bare battery cell 100, thereby reducing the space occupied by the shaping device 200.

[0087] like Figure 9 As shown, in some embodiments of the present invention, the bare cell 100 further includes a third region 130, which is located on the side of the first region 110 away from the second region 120; the shaping device 200 further includes a third clamping assembly 240 and a third pressure plate 270, the third clamping assembly 240 is located on the side of the first clamping assembly 220 away from the second clamping assembly 230, and clamps the inner wall and outer wall of the third region 130; the third pressure plate 270 is located on the side of the first pressure plate 250 away from the second pressure plate 260, and is disposed opposite to the side of the third region 130 away from the support platform 210.

[0088] By including a third region 130 in the bare cell 100 and a third clamping assembly 240 and a third pressure plate 270 in the shaping device 200, the first region 110, the second region 120, and the third region 130 of the bare cell 100 can be shaped in sections. For example, the first region 110 can be shaped by first pressing down the first pressure plate 250, then the second region 120 can be shaped by pressing down the second pressure plate 260, and finally the third region 130 can be shaped by pressing down the third pressure plate 270. The third region 120 can be shaped by: 1) driving the second pressure plate 260 downwards to shape the second region 120; 2) driving the first pressure plate 250 downwards to shape the first region 110; and 3) driving the third pressure plate 270 downwards to shape the third region 130. Alternatively, the first pressure plate 250 can be driven downwards to shape the first region 110; and 4) driving the second pressure plate 260 and the third pressure plate 270 simultaneously to shape the second region 120 and the third region 130 respectively. The size of the third pressure plate 270 can be the same as or different from the size of the first pressure plate 250 or the second pressure plate 260. The area of ​​the third region 130 can be the same as or different from the size of the first region 110 or the second region 120.

[0089] By placing the third region 130 on the side of the first region 110 away from the second region 120, placing the third clamping component 240 on the side of the first clamping component 220 away from the second clamping component 230 and clamping the inner and outer walls of the third region 130, and placing the third pressure plate 270 on the side of the first pressure plate 250 away from the second pressure plate 260 and opposite to the side of the third region 130 away from the support platform 210, the number of partitions of the bare cell 100 is increased. This ensures that the pressure plate corresponding to each region can press down into place after pressing down, further ensuring that the inner ring wall of each region of the bare cell 100 close to the support platform 210 is in close contact with the inner ring wall away from the support platform 210, thereby further reducing the risk of abnormal gaps in the inner ring of the bare cell 100.

[0090] This invention also proposes a shaping method based on the aforementioned shaping device 200. The specific structure of the shaping device 200 is as described in the above embodiments. Since this shaping method is based on the aforementioned shaping device 200, it adopts all the technical solutions of all the above embodiments, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. Please refer to the references provided. Figures 1 to 7 ,as well as Figure 10 The cosmetic surgery method includes:

[0091] S20: Control the first clamping assembly 220 to release the bare battery cell 100 and pull it out of the bare battery cell 100;

[0092] S30: Control the first pressure plate 250 to move toward the support platform 210 so that the surface of the inner wall of the first region 110 near the support platform 210 is in contact with the surface of the inner wall of the first region 110 away from the support platform 210.

[0093] S40: Control the second clamping assembly 230 to release the bare battery cell 100 and pull it out of the bare battery cell 100;

[0094] S50: Control the second pressure plate 260 to move toward the bearing platform 210, and make the second pressure plate 260 flush with the first pressure plate 250.

[0095] During the shaping of the bare battery cell 100, the bare battery cell 100 after the winding needle is removed is placed on the support platform 210, and the bare battery cell 100 is clamped by at least the first clamping assembly 220 and the second clamping assembly 230. Then, the bare battery cell 100 is shaped by the shaping device 200. Specifically, when controlling the first clamping assembly 220 to release the bare battery cell 100 and pull it out of the bare battery cell 100, the first driving member can drive the first clamping assembly 220 to release the bare battery cell 100 along a second direction, wherein the second direction is a direction that forms an angle with the first direction, and the second direction can be parallel to the platform surface of the support platform 210 or form an acute angle or an obtuse angle. When the first driving member drives the first clamping assembly 220 to pull the bare battery cell 100 out of the bare battery cell 100, the first clamping assembly 220 can be driven to pull out along the first direction or in the opposite direction to the first direction. Similarly, when controlling the second clamping assembly 230 to release the bare battery cell 100 and withdraw it from the bare battery cell 100, the second driving member can drive the second clamping assembly 230 to release the bare battery cell 100 first along a second direction, wherein the second direction is at an angle to the first direction, and the second direction can be parallel to the surface of the support platform 210 or at an acute or obtuse angle. When the second driving member drives the second clamping assembly 230 to withdraw from the bare battery cell 100, it can drive the second clamping assembly 230 to withdraw along the first direction or in a direction opposite to the first direction. The direction in which the first clamping assembly 220 is withdrawn from the bare battery cell 100 can be the same as or opposite to the direction in which the second clamping assembly 230 is withdrawn from the bare battery cell 100.

[0096] Understandably, when the unshaped bare battery cell 100 is placed on the support platform 210, the first pressure plate 250 and the second pressure plate 260 are positioned to avoid the bare battery cell 100, for example, above the bare battery cell 100. The first pressure plate 250 can be driven to move towards the support platform 210 via a linear motor, cylinder, lead screw and nut assembly, or gear and rack assembly. Similarly, the second pressure plate 260 can be driven to move towards the support platform 210 via a linear motor, cylinder, lead screw and nut assembly, or gear and rack assembly.

[0097] In addition, when the first pressure plate 250 is moved toward the support platform 210 so that the surface of the inner wall of the first region 110 near the support platform 210 is in contact with the surface of the inner wall of the first region 110 away from the support platform 210, a pressure sensor can be installed on the first pressure plate 250. That is, when the pressure sensor senses that the pressure of the first pressure plate 250 reaches the preset pressure, it is determined that the surface of the inner wall of the first region 110 near the support platform 210 is in contact with the surface of the inner wall of the first region 110 away from the support platform 210. Alternatively, it can be determined whether the surface of the inner wall of the first region 110 near the support platform 210 is in contact with the surface of the inner wall of the first region 110 away from the support platform 210 by controlling whether the movement distance of the first pressure plate 250 reaches the set first distance. When the first pressure plate 250 moves toward the support platform 210 so that the surface of the inner wall of the first region 110 near the support platform 210 is in contact with the surface of the inner wall of the first region 110 away from the support platform 210, by controlling the second pressure plate 260 to move toward the support platform 210 and making the second pressure plate 260 flush with the first pressure plate 250, it can be ensured that the surface of the inner wall of the second region 120 near the support platform 210 and the surface of the inner wall of the second region 120 away from the support platform 210 are also in contact with each other. To determine whether the second pressure plate 260 is flush with the first pressure plate 250, a first sensing element can be provided on the side of the first pressure plate 250 facing the second pressure plate 260. For example, the first sensing element can be a photoelectric sensor or a magnetic sensor. When the second pressure plate 260 moves to a position flush with the first pressure plate 250, the first sensing element receives a signal that the first pressure plate 250 and the second pressure plate 260 are flush and sends the signal to the control module. The control module then controls the second pressure plate 260 to stop moving and maintain the current state. Of course, in other examples, to determine whether the second pressure plate 260 and the first pressure plate 250 are flush, after the second pressure plate 260 moves a second distance toward the support platform 210, a measuring tool can be used to measure whether the surface of the second pressure plate 260 facing the support platform 210 and the surface of the first pressure plate 250 facing the support platform 210 are on the same plane. For example, the measuring tool can be a distance sensor, that is, two distance sensors are set on the support platform 210, and the two distance sensors are respectively set opposite to the first pressure plate 250 and the second pressure plate 260, and respectively measure the distance from the first pressure plate 250 to the support platform 210 and the distance from the second pressure plate 260 to the support platform 210. When the measured values ​​of the two distance sensors are consistent, it is determined that the first pressure plate 250 and the second pressure plate 260 are flush; otherwise, the first pressure plate 250 and the second pressure plate 260 are not flush, and the movement distance of the second pressure plate 260 can be further adjusted.

[0098] By first controlling the first clamping component 220 to release the bare cell 100 and pull it out of the bare cell 100, while the second clamping component 230 still clamps the bare cell 100, when the first clamping component 220 is pulled out of the bare cell 100, the electrode and separator of the first region 110 of the bare cell 100 are hindered from rebounding because the second clamping component 230 is clamping the second region 120. As a result, when the first pressure plate 250 is controlled to move towards the support platform 210 to press down on the first region 110, the inner ring of the first region 110 is less likely to have abnormal gaps due to the rebound of the electrode and separator. By controlling the first pressure plate 250 to move towards the support platform 210 and then controlling the second clamping assembly 230 to release the bare cell 100, when the second clamping assembly 230 releases the bare cell 100 and is pulled out of the bare cell 100, the rebound of the electrode and separator corresponding to the second region 120 is hindered by the first pressure plate 250 pressing the first region 110. Therefore, when the second pressure plate 260 moves towards the support platform 210 to press down and shape the second region 120, the second region 120 is less likely to have abnormal gaps due to the rebound of the electrode and separator. This allows both the first region 110 and the second region 120 to be compacted, greatly reducing the risk of abnormal gaps in the first region 110 and the second region 120.

[0099] Please refer to the reference. Figure 1 , Figure 2 as well as Figure 11 In some embodiments of the present invention, step S20, which involves controlling the first clamping assembly 220 to release the bare battery cell 100 and extract it from the bare battery cell 100, further includes the following steps before the step:

[0100] S10: Control both the first pressure plate 250 and the second pressure plate 260 to press down a preset distance.

[0101] Specifically, the first pressure plate 250 and the second pressure plate 260 can be controlled to press down simultaneously by a preset distance, or the first pressure plate 250 and the second pressure plate 260 can be controlled to press down by a preset distance separately. It should be noted that, in this embodiment, after the first pressure plate 250 and the second pressure plate 260 are pressed down by a preset distance, the wall surface of the inner ring of the bare battery cell 100 near the support platform 210 and the wall surface of the inner ring away from the support platform 210 are not in contact.

[0102] By driving the first pressure plate 250 and the second pressure plate 260 to press down a preset distance before the first clamping assembly 220 releases the bare battery cell 100 and pulls it out of the bare battery cell 100, a pre-shaping effect is achieved on the bare battery cell 100. This facilitates reducing the pressure of the first pressure plate 250 when pressing the first region 110 and the pressure of the second pressure plate 260 when pressing the second region 120, thereby improving the service life of the first pressure plate 250 and the second pressure plate 260. In addition, this arrangement also makes it easier for the first pressure plate 250 and the second pressure plate 260 to press the bare battery cell 100 tightly afterward, so that the surface of the inner wall of the bare battery cell 100 near the support platform 210 is in close contact with the surface of the inner wall of the bare battery cell 100 away from the support platform 210.

[0103] Please refer to the reference. Figure 9 and Figure 12 In some embodiments of the present invention, the bare cell 100 further includes a third region 130, which is located on the side of the first region 110 away from the second region 120; the shaping device 200 further includes a third clamping assembly 240 and a third pressure plate 270, the third clamping assembly 240 being located on the side of the first clamping assembly 220 away from the second clamping assembly 230, and clamping the inner and outer walls of the third region 130; the third pressure plate 270 being located on the side of the first pressure plate 250 away from the second pressure plate 260, and being disposed opposite to the side of the third region 130 away from the support platform 210; after step S30: controlling the first pressure plate 250 to move toward the support platform 210, the method further includes:

[0104] S60: Control the third clamping assembly 240 to release the bare battery cell 100 and pull it out of the bare battery cell 100;

[0105] S70: Control the third pressure plate 270 to move toward the support platform 210, and make the third pressure plate 270 flush with the first pressure plate 250.

[0106] When the third clamping assembly 240 is controlled to release the bare battery cell 100 and withdraw it from the bare battery cell 100, the third driving member can drive the third clamping assembly 240 to release the bare battery cell 100 first along a second direction. The second direction is an angled direction to the first direction, and the second direction can be parallel to, at an acute angle to, or at an obtuse angle to the surface of the support platform 210. When the third driving member drives the third clamping assembly 240 to withdraw from the bare battery cell 100, it can drive the third clamping assembly 240 to withdraw along the first direction or in a direction opposite to the first direction. The direction in which the first clamping assembly 220 is controlled to withdraw from the bare battery cell 100 can be the same as or opposite to the direction in which the third clamping assembly 240 is controlled to withdraw from the bare battery cell 100. When the third pressure plate 270 moves toward the bearing platform 210, the first pressure plate 250 can be driven to move by a linear motor, cylinder, lead screw and nut assembly or gear and rack assembly.

[0107] Furthermore, in this embodiment, the step of controlling the third clamping assembly 240 to release the bare battery cell 100 and withdraw it from the bare battery cell 100 can be performed simultaneously with the step of controlling the second clamping assembly 230 to release the bare battery cell 100 and withdraw it from the bare battery cell 100, or they can be performed sequentially, as long as the movement of the second clamping assembly 230 and the movement of the third clamping assembly 240 do not interfere with each other when the two steps are performed. Similarly, the step of controlling the third pressure plate 270 to move towards the support platform 210 and making the third pressure plate 270 flush with the first pressure plate 250 can be performed simultaneously with the step of "controlling the second pressure plate 260 to move towards the support platform 210 and making the second pressure plate 260 flush with the first pressure plate 250", or they can be performed sequentially.

[0108] To determine whether the third pressure plate 270 is flush with the first pressure plate 250, a second sensor can be installed on the side of the first pressure plate 250 facing the third pressure plate 270. For example, the second sensor can be a photoelectric sensor or a magnetic sensor. When the third pressure plate 270 moves to a position flush with the first pressure plate 250, the second sensor receives a signal that the first pressure plate 250 and the third pressure plate 270 are flush and sends the signal to the control module. The control module then controls the third pressure plate 270 to stop moving and maintain its current state. Of course, in other examples, to determine whether the third pressure plate 270 and the first pressure plate 250 are flush, after the third pressure plate 270 moves a third distance toward the support platform 210, a measuring tool can be used to measure whether the surface of the third pressure plate 270 facing the support platform 210 and the surface of the first pressure plate 250 facing the support platform 210 are on the same plane. For example, the measuring tool can be a distance sensor, that is, two distance sensors are set on the support platform 210, and the two distance sensors are respectively set opposite to the first pressure plate 250 and the third pressure plate 270, and respectively measure the distance from the first pressure plate 250 to the support platform 210 and the distance from the third pressure plate 270 to the support platform 210. When the measured values ​​of the two distance sensors are consistent, it is determined that the first pressure plate 250 and the third pressure plate 270 are flush; otherwise, the first pressure plate 250 and the third pressure plate 270 are not flush, and the movement distance of the third pressure plate 270 can be further adjusted.

[0109] By including a third region 130 in the bare cell 100 and a third clamping assembly 240 and a third pressure plate 270 in the shaping device 200, the bare cell 100 can be divided into more regions, and multiple regions can be pressed down and shaped separately. This allows each pressure plate to shape a smaller region, thereby improving the shaping quality of each region and further reducing the risk of abnormal gaps in the inner ring of the bare cell 100.

[0110] In some embodiments of the present invention, step S40: controlling the second clamping assembly 230 to release the bare battery cell 100 and extract it from the bare battery cell 100 is performed simultaneously with step S60: controlling the third clamping assembly 240 to release the bare battery cell 100 and extract it from the bare battery cell 100; step S50: controlling the second pressure plate 260 to move toward the support platform 210 and step S70: controlling the third pressure plate 270 to move toward the support platform 210 are performed simultaneously.

[0111] Specifically, the direction in which the second clamping assembly 230 releases the bare battery cell 100 and pulls it out of the bare battery cell 100 can be the same as or different from the direction in which the third clamping assembly 240 releases the bare battery cell 100 and pulls it out of the bare battery cell 100.

[0112] By simultaneously performing the steps of controlling the second clamping assembly 230 to release the bare battery cell 100 and extract it from the bare battery cell 100, and controlling the third clamping assembly 240 to release the bare battery cell 100 and extract it from the bare battery cell 100, and by simultaneously performing the steps of controlling the second pressure plate 260 to move toward the support table 210 and controlling the third pressure plate 270 to move toward the support table 210, the shaping efficiency of the shaping equipment 200 can be improved.

[0113] Please refer to the reference. Figure 13 and Figure 14 In some embodiments of the present invention, step S40: controlling the second clamping assembly 230 to release the bare battery cell 100 and extract it from the bare battery cell 100 specifically includes:

[0114] S41: Control the second clamping assembly 230 to release the bare battery cell 100;

[0115] S42: Control the second clamping assembly 230 to be pulled out from the bare cell 100 along the first direction;

[0116] S60: The step of controlling the third clamping assembly 240 to release the bare battery cell 100 and extract it from the bare battery cell 100 specifically includes:

[0117] S61: Control the third clamping assembly 240 to release the bare battery cell 100;

[0118] S62: Control the third clamping assembly 240 to be pulled out from the bare cell 100 along a direction away from the first direction.

[0119] By controlling the second clamping assembly 230 to be withdrawn from the bare battery cell 100 along the first direction and the third clamping assembly 240 to be withdrawn from the bare battery cell 100 along the direction opposite to the first direction, the risk of interference between the second clamping assembly 230 and the third clamping assembly 240 when they are withdrawn simultaneously can be further reduced. Furthermore, this configuration can improve the extraction efficiency of the second clamping assembly 230 and the third clamping assembly 240 from the bare battery cell 100, thereby improving the shaping efficiency of the shaping device 200.

[0120] The present invention also proposes a battery production line, including a shaping device 200. The specific structure of the shaping device 200 is as described in the above embodiments. Since the battery production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0121] The above are merely exemplary embodiments of the present invention and do not limit the scope of the patent of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
