Description

Technical Field

[0001] The present application relates to the technical field of battery processing equipment, and particularly to a core blanking and pressing device for winding equipment and a core winding equipment. Background Art

[0002] In the process of processing and manufacturing cores, there is a process of flattening the cores. Specifically, the cores are usually flattened by a core blanking and pressing device for winding equipment. In order to ensure the flattening effect, after the core blanking and pressing device for winding equipment flattens the cores, it is also necessary to maintain pressure for a period of time. However, maintaining pressure on the cores takes some time, resulting in a low flattening efficiency of the core blanking and pressing device for winding equipment, and thus a low processing efficiency of the core winding equipment. Summary of the Invention

[0003] The present application discloses a core blanking and pressing device for winding equipment and a core winding equipment, which have a high flattening efficiency, thereby enabling the core winding equipment to have a high processing efficiency.

[0004] To achieve the above object, in a first aspect, the present application discloses a core blanking and pressing device for winding equipment, including:

[0005] A flattening assembly, the flattening assembly includes a first flattening member, a second flattening member and a third flattening member, the first flattening member, the second flattening member and the third flattening member are arranged at intervals and stacked in a first direction, and the second flattening member and the third flattening member are slidably arranged along the first direction; and,

[0006] A driving assembly, the driving assembly is located on a side of the third flattening member away from the second flattening member, and at least one second flattening member is arranged between the first flattening member and the third flattening member.

[0007] Since the first flattening member, the second flattening member and the third flattening member are arranged at intervals and stacked in the first direction, and the second flattening member and the third flattening member are slidably arranged along the first direction, and since the driving assembly is located on a side of the third flattening member away from the second flattening member, therefore, when cores are placed on a surface of the first flattening member facing the second flattening member and a surface of the second flattening member facing the third flattening member, when the driving assembly drives the third flattening member to move in a direction close to the second flattening member, so that the core on the second flattening member is clamped between the third flattening member and the second flattening member, the driving assembly can also drive the second flattening member to move in the first direction close to the first flattening member, so that the core on the first flattening member is clamped between the first flattening member and the second flattening member.

[0008] And when the battery cell on the second flattening piece is clamped between the third flattening piece and the second flattening piece, and when the battery cell on the first flattening piece is clamped between the first flattening piece and the second flattening piece, by keeping the driving component stationary, the battery cell on the second flattening piece and the battery cell on the first flattening piece can be continuously subjected to the clamping force, forming a pressure-maintaining effect, thereby allowing the battery cell on the second flattening piece and the battery cell on the first flattening piece to be well flattened.

[0009] It can be seen from this that when the driving component drives the third flattening piece to move, the battery cell on the first flattening piece can be clamped between the first flattening piece and the second flattening piece, thereby flattening the battery cell on the first flattening piece. At the same time, the battery cell on the second flattening piece can be clamped between the third flattening piece and the second flattening piece, thereby flattening the battery cell on the second flattening piece. Moreover, when the battery cell on the first flattening piece is clamped between the first flattening piece and the second flattening piece, and the battery cell on the second flattening piece is clamped between the third flattening piece and the second flattening piece, by keeping the driving component stationary, the battery cell on the second flattening piece and the battery cell on the first flattening piece can continue to be subjected to the clamping force, thereby forming a pressure-maintaining effect.

[0010] That is, the battery cell cutting and pressing device for the winding device can flatten the battery cells on the first flattening piece and the battery cells on the second flattening piece at the same time, and can also maintain the pressure of the battery cells on the first flattening piece and the battery cells on the second flattening piece at the same time. In layman's terms, the battery cell cutting and pressing device for the winding device can flatten multiple battery cells at one time and maintain the pressure of multiple battery cells at one time, so that the efficiency of the battery cell cutting and pressing device for the winding device in flattening the battery cells can be improved. Based on this, when the battery cell cutting and pressing device for the winding device is applied to the battery cell winding device, the processing efficiency of the battery cell winding device can be improved.

[0011] Optionally, the driving assembly comprises:

[0012] a first driving member; and

[0013] A pressing member is connected to the first driving member and is located at a side of the third flattening member away from the second flattening member.

[0014] Optionally, the flattening component further comprises:

[0015] A second driving member is disposed on the first flattening member and connected to the second flattening member.

[0016] By providing the second driving member, on the one hand, in addition to driving the pressing member to move towards the third flattening member along the first direction through the first driving member to flatten the battery cell on the first flattening member, the second driving member can also drive the second flattening member to move towards the first flattening member along the first direction to flatten the battery cell on the first flattening member. That is to say, the battery cell on the first flattening member can be subjected to a double flattening effect, and the flattening effect is better. On the other hand, the second driving member can drive the second flattening member to move away from the first flattening member along the first direction, so that the gap between the second flattening member and the first flattening member along the first direction becomes larger, which is conducive to placing the battery cell on the surface of the first flattening member facing the second flattening member, making it relatively simple to place the battery cell on the surface of the first flattening member facing the second flattening member.

[0017] Optionally, the flattening assembly further includes:

[0018] A third driving member, which is disposed on the second flattening member and connected to the third flattening member.

[0019] By providing the third driving member, on the one hand, in addition to driving the pressing member to move towards the third flattening member along the first direction through the first driving member to flatten the battery cell on the second flattening member, the third driving member can also drive the third flattening member to move towards the second flattening member along the first direction to flatten the battery cell on the second flattening member. That is to say, the battery cell on the second flattening member can be subjected to a double flattening effect, and the flattening effect is better. On the other hand, the third driving member can drive the third flattening member to move away from the second flattening member along the first direction, so that the gap between the third flattening member and the second flattening member along the first direction becomes larger, which is conducive to placing the battery cell on the surface of the second flattening member facing the third flattening member, making it relatively simple to place the battery cell on the surface of the second flattening member facing the third flattening member.

[0020] Optionally, the battery cell blanking and pressing device for the winding equipment further includes:

[0021] A heightening assembly, which includes a fourth driving member and a heightening member. The fourth driving member is disposed on the third flattening member, and the heightening member is connected to the fourth driving member. The fourth driving member is used to drive the heightening member to move between the third flattening member and the driving assembly or move away from between the third flattening member and the driving assembly.

[0022] In this way, the stroke of the pressing member along the first direction can be shortened to a certain extent, and then the time taken for the pressing member to move along the first direction can be shortened, thereby further improving the flattening efficiency of the battery cell blanking and pressing device for the winding equipment.

[0023] Optionally, a first conveyor belt is sleeved on the first flattening member, and a partial belt body of the first conveyor belt is attached to a surface of the first flattening member facing the second flattening member.

[0024] Since the first conveyor belt is sleeved on the first flattening member, and a partial belt body of the first conveyor belt is attached to a surface of the first flattening member facing the second flattening member, when it is necessary to place the battery cell on the surface of the first flattening member facing the second flattening member, the battery cell can be first placed on the first conveyor belt, and then the first conveyor belt can be started to run. When the first conveyor belt starts to run, the battery cell can be conveyed to the surface of the first flattening member facing the second flattening member, thereby achieving the purpose of placing the battery cell on the surface of the first flattening member facing the second flattening member. It is very convenient, with a high degree of automation, and can reduce the labor intensity of personnel.

[0025] Optionally, a second conveyor belt is sleeved on the second flattening member, and a partial belt body of the second conveyor belt is attached to a surface of the second flattening member facing the third flattening member.

[0026] Since the second conveyor belt is sleeved on the second flattening member, and a partial belt body of the second conveyor belt is attached to a surface of the second flattening member facing the third flattening member, when it is necessary to place the battery cell on the surface of the second flattening member facing the third flattening member, the battery cell can be first placed on the second conveyor belt, and then the second conveyor belt can be started to run. When the second conveyor belt starts to run, the battery cell can be conveyed to the surface of the second flattening member facing the third flattening member, thereby achieving the purpose of placing the battery cell on the surface of the second flattening member facing the third flattening member. It is very convenient, with a high degree of automation, and can reduce the labor intensity of personnel.

[0027] Optionally, the flattening assembly further includes:

[0028] A fourth flattening member, which is disposed on a side of the second flattening member facing the first flattening member. A belt-passing slit is formed between the fourth flattening member and the second flattening member, and at least a partial belt body of the second conveyor belt facing the first flattening member passes through the belt-passing slit.

[0029] Since the fourth flattening member is disposed on the side of the second flattening member facing the first flattening member, a belt-passing slit is formed between the fourth flattening member and the second flattening member, and at least a part of the belt body of the second conveyor belt facing the first flattening member is passed through the belt-passing slit. Therefore, the fourth flattening member can semi-wrap the second conveyor belt on the side of the second flattening member facing the first flattening member. In this way, when the first driving member drives the pressing member to move in the first direction towards the third flattening member, the battery cell on the first flattening member can be clamped between the fourth flattening member and the first flattening member. That is to say, the fourth flattening member can replace the second flattening member to jointly clamp the battery cell on the first flattening member with the first flattening member, thereby avoiding the interference between the second conveyor belt and the battery cell on the first flattening member, and enabling the battery cell on the first flattening member to be well flattened jointly by the fourth flattening member and the first flattening member.

[0030] Optionally, the conveying directions of the first conveyor belt and the second conveyor belt are both the second direction.

[0031] By making the conveying directions of the first conveyor belt and the second conveyor belt the same, on the one hand, the layout between the first conveyor belt and the second conveyor belt can be made more regular, which is convenient for the layout of the first conveyor belt and the second conveyor belt. On the other hand, it can also make the conveying directions of the battery cells on the first conveyor belt and the second conveyor belt the same, and further make the feeding of the battery cells more regular and simple.

[0032] In addition, by making the second direction perpendicular to the first direction, when the first direction is the vertical direction, the second direction can be the horizontal direction. In this way, the conveying of the battery cells on the first conveyor belt and the second conveyor belt can be made more stable.

[0033] Optionally, it further includes a feeding assembly, and the feeding assembly is located on one side of the first flattening member or the second flattening member for feeding the first flattening member and the second flattening member.

[0034] Optionally, the feeding assembly includes:

[0035] A first moving assembly; and,

[0036] A feeding conveyor belt, the feeding conveyor belt is disposed on the first moving assembly, and the first moving assembly is used to drive the feeding conveyor belt to move in the first direction.

[0037] Optionally, the feeding assembly includes:

[0038] Multiple feeding conveyor belts, and one of the multiple feeding conveyor belts is correspondingly disposed for each of the first flattening member and each second flattening member.

[0039] Optionally, the battery cell unloading and pressing device for the winding equipment further includes an unloading component, which is located on the side of the first flattening piece or the second flattening piece opposite to the loading component, and is used for unloading the first flattening piece and the second flattening piece.

[0040] Optionally, the unloading assembly includes a second moving assembly and an unloading conveyor belt, the unloading conveyor belt is arranged on the second moving assembly, and the second moving assembly is used to drive the unloading conveyor belt to move along the first direction.

[0041] By making the second moving component drive the unloading conveyor belt to move along the first direction, the battery cells on the first conveyor belt and the second conveyor belt can be automatically unloaded respectively through the same unloading conveyor belt. On the one hand, the unloading work of the battery cells on the first conveyor belt and the second conveyor belt can be made more automated. On the other hand, since there is no need to set up special unloading conveyor belts for the first conveyor belt and the second conveyor belt respectively, the number of unloading conveyor belts can be saved, the structure of the unloading component can be simplified, and the cost of the unloading component can be reduced.

[0042] Optionally, the blanking assembly comprises:

[0043] A plurality of unloading conveyor belts, wherein the first flattening member and each of the second flattening members are correspondingly provided with one of the plurality of unloading conveyor belts.

[0044] Optionally, a supporting frame is further included, wherein the supporting frame includes:

[0045] A guide rod extending along the first direction, and the second flattening member and the third flattening member are slidably disposed on the guide rod along the first direction;

[0046] A mounting member is arranged on the guide rod and is located at a side of the third flattening member away from the second flattening member, and the driving assembly is arranged on the mounting member.

[0047] Since the second flattening member and the third flattening member are slidably disposed on the guide rod along the first direction, under the guiding action of the guide rod, the second flattening member and the third flattening member can slide more steadily and smoothly along the first direction.

[0048] In a second aspect, the present application discloses a battery cell winding device, comprising a battery cell blanking and pressing device for a winding device as described in any one of the first aspects above.

[0049] Since the cell blanking and pressing device for winding equipment can flatten multiple cells at one time and maintain pressure on multiple cells at one time, the efficiency of the cell blanking and pressing device for winding equipment in flattening cells can be improved. Based on this, when the cell blanking and pressing device for winding equipment is applied to the cell winding equipment, the processing efficiency of the cell winding equipment can be improved.

[0050] Optionally, it also includes:

[0051] A winding mechanism, the winding mechanism is used for winding the battery core;

[0052] Feeding mechanism;

[0053] A conveying mechanism, wherein the unloading mechanism is used to unload the battery cells to the conveying mechanism;

[0054] A pre-pressing mechanism, wherein the pre-pressing mechanism is used to pre-press the battery cell on the conveying mechanism, and the conveying mechanism is used to convey the pre-pressed battery cell to the first flattening member or the second flattening member.

[0055] When the battery cell winding device also includes a pre-pressing mechanism, since the pre-pressing mechanism can perform preliminary flattening on the battery cell, it prepares for subsequent secondary flattening at the first flattening piece or the second flattening piece, thereby making the battery cell flattening effect produced by the battery cell winding device better.

[0056] When the battery cell winding equipment also includes a unloading mechanism and a conveying mechanism, the unloading mechanism can automatically unload the battery cells on the winding needle onto the conveying mechanism, and the conveying mechanism can automatically convey the battery cells after preliminary flattening to the first flattening piece or the second flattening piece. The entire process can be completed automatically without the need for human participation. Therefore, the degree of automation of the entire battery cell winding equipment can be made higher.

[0057] Compared with the prior art, the beneficial effects of this application are:

[0058] In the present application, since the first flattening piece, the second flattening piece and the third flattening piece are stacked at intervals along the first direction, the second flattening piece and the third flattening piece are slidably arranged along the first direction, and since the driving component is located on the side of the third flattening piece away from the second flattening piece, therefore, when battery cells are placed on a side of the first flattening piece facing the second flattening piece and a side of the second flattening piece facing the third flattening piece, when the driving component drives the third flattening piece to move toward the direction close to the second flattening piece, so that the battery cell on the second flattening piece is clamped between the third flattening piece and the second flattening piece, the driving component can also drive the second flattening piece to move along the first direction toward the direction close to the first flattening piece, so that the battery cell on the first flattening piece is clamped between the first flattening piece and the second flattening piece.

[0059] It can be seen that when the driving component drives the third flattening member to move, the battery cell on the first flattening member can be clamped between the first flattening member and the second flattening member. Thus, while flattening the battery cell on the first flattening member, the battery cell on the second flattening member can also be clamped between the third flattening member and the second flattening member, thereby flattening the battery cell on the second flattening member. Moreover, when the battery cell on the first flattening member is clamped between the first flattening member and the second flattening member, and the battery cell on the second flattening member is clamped between the third flattening member and the second flattening member, by keeping the driving component stationary, the battery cells on the second flattening member and the first flattening member can both continuously receive clamping force, achieving the effect of pressure holding.

[0060] That is to say, the battery cell blanking and pressing device for the winding equipment can flatten the battery cells on the first flattening member and the second flattening member simultaneously, and can also perform pressure holding on the battery cells on the first flattening member and the second flattening member simultaneously. Generally speaking, the battery cell blanking and pressing device for the winding equipment can flatten multiple battery cells at one time and perform pressure holding on multiple battery cells at one time. In this way, the efficiency of flattening the battery cells by the battery cell blanking and pressing device for the winding equipment can be improved. Based on this, when the battery cell blanking and pressing device for the winding equipment is applied to the battery cell winding equipment, the processing efficiency of the battery cell winding equipment can be improved.

[0085] Before explaining the technical solution of this application, the background technology of this application will be described first.

[0086] In the process of processing and manufacturing the battery cell, there is a process of flattening the battery cell. Specifically, usually, the battery cell is flattened by a battery cell blanking and pressing device for winding equipment. In order to ensure the flattening effect, after the battery cell blanking and pressing device for winding equipment flattens the battery cell, it is also necessary to keep the pressure for a period of time. However, keeping the pressure on the battery cell takes some time, resulting in a low flattening efficiency of the battery cell blanking and pressing device for winding equipment, and further resulting in a low processing efficiency of the battery cell winding equipment. Based on this, this application provides a new battery cell blanking and pressing device for winding equipment to solve the above problems.

[0087] Next, the technical solution of this application will be described in conjunction with specific embodiments and drawings.

[0088] Figure 1 FIG. 1 is a schematic diagram of a structure of a battery cell blanking and pressing device 100 for a winding device provided in an embodiment of the present application, see Figure 1 The battery cell blanking and pressing device 100 for winding equipment includes a supporting frame 1, a flattening assembly 2 and a driving assembly 3, wherein the flattening assembly 2 includes a first flattening member 21, a second flattening member 22 and a third flattening member 23, and the first flattening member 21, the second flattening member 22 and the third flattening member 23 are arranged along a first direction ( Figure 1 The second flattening member 22 and the third flattening member 23 are slidably disposed on the support frame 1 along the first direction.

[0089] The driving assembly 3 is located on a side of the third flattening member 23 facing away from the second flattening member 22 , and at least one second flattening member 22 is disposed between the first flattening member 21 and the third flattening member 23 .

[0090] Specifically, the driving assembly 3 includes a first driving member 31 and a pressing member 32. The first driving member 31 is disposed on the supporting frame 1. The pressing member 32 is connected to the first driving member 31 and is located on a side of the third flattening member 23 away from the second flattening member 22 ( Figure 1 The first driving member 31 is used to drive the pressing member 32 to approach ( Figure 1 in the negative direction of the Z axis) or away from ( Figure 1 The third flattening member 23 moves in the positive direction of the center Z axis.

[0091] In this embodiment, when the battery cell D is flattened by the battery cell blanking and pressing device 100 for winding equipment, the first flattening member 21, the second flattening member 22 and the third flattening member 23 are arranged along the first direction ( Figure 1 The first flattening member 21 is stacked in a spaced manner in the Z-axis direction, so that the first flattening member 21 can be stacked in a spaced manner on one side ( Figure 1 The first flattening member 21 is disposed on the upper surface of the first flattening member 21 and the second flattening member 22 is disposed on the side facing the third flattening member 23 ( Figure 1 The battery cells D are placed on the upper surface of the second flattening piece 22 in the middle), then, since the second flattening piece 22 and the third flattening piece 23 are slidably arranged along the first direction, specifically, the second flattening piece 22 and the third flattening piece 23 can be slidably arranged on the support frame 1 along the first direction, and since the driving component 3 is located on the side of the third flattening piece 23 away from the second flattening piece 22, specifically, the first driving member 31 is arranged on the support frame 1, the clamping member 32 is connected to the first driving member 31 and is located on the side of the third flattening piece 23 away from the second flattening piece 22, therefore, the first driving member 31 can drive the clamping member 32 to move along the first direction toward the third flattening piece 23.

[0092] As the first driving member 31 drives the pressing member 32 to move in the first direction towards the third flattening member 23 ( Figure 1 in the negative Z-axis direction in FIG. Figure 1 ), the pressing member 32 can move to contact the third flattening member 23. When the pressing member 32 contacts the third flattening member 23, when the first driving member 31 drives the pressing member 32 to continue moving in the first direction towards the third flattening member 23, the pressing member 32 can push the third flattening member 23 to move towards the second flattening member 22, so that the battery cell D on the second flattening member 22 is clamped between the third flattening member 23 and the second flattening member 22, and thus the battery cell D on the second flattening member 22 can be flattened.

[0093] Meanwhile, when the battery cell D on the second flattening member 22 is clamped between the third flattening member 23 and the second flattening member 22, the power of the driving assembly 3, specifically, the power of the pressing member 32 can also be transmitted to the second flattening member 22 through the third flattening member 23 and the battery cell D on the second flattening member 22, so that the second flattening member 22 can move in the first direction towards the first flattening member 21, and thus the battery cell D on the first flattening member 21 can be clamped between the first flattening member 21 and the second flattening member 22. When the battery cell D on the first flattening member 21 is clamped between the first flattening member 21 and the second flattening member 22, the battery cell D on the first flattening member 21 can also be flattened.

[0094] When the battery cell D on the second flattening member 22 is clamped between the third flattening member 23 and the second flattening member 22, so that the battery cell D on the second flattening member 22 is flattened, and the battery cell D on the first flattening member 21 is clamped between the first flattening member 21 and the second flattening member 22, so that the battery cell D on the first flattening member 21 is also flattened, the pressing member 32 can remain stationary. At this time, the battery cell D on the second flattening member 22 and the battery cell D on the first flattening member 21 can continuously receive the clamping force, forming a pressure maintaining effect, and thus the battery cell D on the second flattening member 22 and the battery cell D on the first flattening member 21 can both be flattened well.

[0095] It can be seen that since the first flattening piece 21, the second flattening piece 22 and the third flattening piece 23 are arranged in an interval and stacked manner along the first direction, the second flattening piece 22 and the third flattening piece 23 are slidably arranged along the first direction, and since the driving component 3 is located on the side of the third flattening piece 23 away from the second flattening piece 22, therefore, when the battery cell D is placed on the side of the first flattening piece 21 facing the second flattening piece 22 and the side of the second flattening piece 22 facing the third flattening piece 23, when the driving component 3 drives the third flattening piece 23 to move toward the second flattening piece 22, so that the battery cell D on the second flattening piece 22 is clamped between the third flattening piece 23 and the second flattening piece 22, the driving component 3 can also drive the second flattening piece 22 to move along the first direction toward the first flattening piece 21, so that the battery cell D on the first flattening piece 21 is clamped between the first flattening piece 21 and the second flattening piece 22.

[0096] And when the battery cell D on the second flattening piece 22 is clamped between the third flattening piece 23 and the second flattening piece 22, and the battery cell D on the first flattening piece 21 is clamped between the first flattening piece 21 and the second flattening piece 22, by keeping the driving component 3 stationary, the battery cell D on the second flattening piece 22 and the battery cell D on the first flattening piece 21 can be continuously subjected to the clamping force, forming a pressure-maintaining effect, thereby allowing the battery cell D on the second flattening piece 22 and the battery cell D on the first flattening piece 21 to be well flattened.

[0097] It can be seen that when the driving component 3 drives the third flattening piece 23 to move, the battery cell D on the first flattening piece 21 can be clamped between the first flattening piece 21 and the second flattening piece 22, thereby flattening the battery cell D on the first flattening piece 21, and the battery cell D on the second flattening piece 22 can be clamped between the third flattening piece 23 and the second flattening piece 22, thereby flattening the battery cell D on the second flattening piece 22. In addition, when the battery cell D on the first flattening piece 21 is clamped between the first flattening piece 21 and the second flattening piece 22, and the battery cell D on the second flattening piece 22 is clamped between the third flattening piece 23 and the second flattening piece 22, by keeping the driving component 3 stationary, the battery cell D on the second flattening piece 22 and the battery cell D on the first flattening piece 21 can continue to be subjected to the clamping force, thereby forming a pressure-maintaining effect.

[0098] That is to say, the cell blanking and pressing device 100 for the winding device can simultaneously flatten the cells D on the first flattening member 21 and the cells D on the second flattening member 22, and can also simultaneously maintain the pressure on the cells D on the first flattening member 21 and the cells D on the second flattening member 22. Generally speaking, the cell blanking and pressing device 100 for the winding device can flatten multiple cells D at one time and maintain the pressure on multiple cells D at one time. In this way, the efficiency of flattening the cells D by the cell blanking and pressing device 100 for the winding device can be improved. Based on this, when the cell blanking and pressing device 100 for the winding device is applied to the cell winding device 200, the processing efficiency of the cell winding device 200 can be improved.

[0099] Among them, the above-mentioned first flattening member 21, second flattening member 22 and third flattening member 23 can all be hot plates or any other components capable of flattening the cell D, and this embodiment does not make any limitations in this regard.

[0100] The above-mentioned first direction can be the vertical direction or approximately the vertical direction. When the first direction is the vertical direction, the surface of the first flattening member 21 facing the second flattening member 22 and the surface of the second flattening member 22 facing the third flattening member 23 can be horizontal planes. In this way, the cells D placed on the surface of the first flattening member 21 facing the second flattening member 22 and the surface of the second flattening member 22 facing the third flattening member 23 can be made more stable and not easily fall off.

[0101] The above-mentioned first driving member 31 can be a cylinder, a hydraulic cylinder, a motor screw nut mechanism, etc., and this embodiment does not make any limitations in this regard. The pressing member 32 can be a plate-shaped part or any other shaped part, as long as it is convenient to push the third flattening member 23 to move along the first direction through the pressing member 32, and this embodiment does not make any limitations in this regard.

[0102] It should be noted that the number of the above-mentioned second flattening members 22 can be one, or two, three, four, etc., and this embodiment does not make any limitations in this regard.

[0103] Among them, when the number of the second flattening members 22 is multiple, in the case where cells D are placed between two adjacent second flattening members 22, the cells D between two adjacent second flattening members 22 can be clamped between the two second flattening members 22 and flattened.

[0104] In some embodiments, refer to Figure 2 , Figure 2 is a schematic structural diagram of another cell blanking and pressing device 100 for a winding device provided in an embodiment of the present application. The flattening assembly 2 further includes a second driving member 24. The second driving member 24 is disposed on the first flattening member 21 and connected to the second flattening member 22. The second driving member 24 is used to drive the second flattening member 22 along the first direction (Figure 2 It moves in the Z-axis direction (towards or away from the first flattening member 21).

[0105] Since the second driving member 24 is disposed on the first flattening member 21 and connected to the second flattening member 22, the second driving member 24 can drive the second flattening member 22 to move in the first direction towards or away from the first flattening member 21. When the second driving member 24 drives the second flattening member 22 to move away from the first flattening member 21 in the first direction, the gap between the second flattening member 22 and the first flattening member 21 in the first direction can be increased, which is conducive to placing the battery cell D on the surface of the first flattening member 21 facing the second flattening member 22. When the second driving member 24 drives the second flattening member 22 to move towards the first flattening member 21 in the first direction, the battery cell D can be clamped between the first flattening member 21 and the second flattening member 22, and thus the purpose of flattening the battery cell D on the first flattening member 21 can be achieved.

[0106] It can be seen that by providing the second driving member 24, on the one hand, in addition to driving the pressing member 32 to move towards the third flattening member 23 in the first direction through the first driving member 31 to achieve the purpose of flattening the battery cell D on the first flattening member 21, the second driving member 24 can also drive the second flattening member 22 to move towards the first flattening member 21 in the first direction to achieve the purpose of flattening the battery cell D on the first flattening member 21. That is to say, the battery cell D on the first flattening member 21 can be subjected to a double flattening effect, and the flattening effect is better. On the other hand, the second driving member 24 can drive the second flattening member 22 to move away from the first flattening member 21 in the first direction, so that the gap between the second flattening member 22 and the first flattening member 21 in the first direction is increased, which is conducive to placing the battery cell D on the surface of the first flattening member 21 facing the second flattening member 22, making it relatively simple to place the battery cell D on the surface of the first flattening member 21 facing the second flattening member 22.

[0107] It should be noted that the above-mentioned second driving member 24 can be any structure such as a cylinder or an electric cylinder that can drive the second flattening member 22 to move towards or away from the first flattening member 21 in the first direction, and this embodiment does not make any limitation in this regard.

[0108] The number of the above-mentioned second driving members 24 can be one. Of course, the number of the second driving members 24 can also be multiple, and this embodiment does not make any limitation in this regard.

[0109] Further, in some embodiments, refer to Figure 3 , Figure 3FIG. 0 is a schematic structural diagram of another cell blanking and pressing device 100 for a winding device provided by an embodiment of the present application. The flattening assembly 2 further includes a third driving member 25. The third driving member 25 is disposed on the second flattening member 22 and connected to the third flattening member 23. The third driving member 25 is configured to drive the third flattening member 23 to move in a first direction toward or away from the second flattening member 22.

[0110] Since the third driving member 25 is disposed on the second flattening member 22 and connected to the third flattening member 23, the third driving member 25 can drive the third flattening member 23 to move in a first direction toward or away from the second flattening member 22. When the third driving member 25 drives the third flattening member 23 to move in the first direction away from the second flattening member 22, the gap between the third flattening member 23 and the second flattening member 22 in the first direction can be increased, which is conducive to placing the cell D on the surface of the second flattening member 22 facing the third flattening member 23. When the third driving member 25 drives the third flattening member 23 to move in the first direction toward the second flattening member 22, the cell D can be clamped between the third flattening member 23 and the second flattening member 22, and thus the purpose of flattening the cell D on the second flattening member 22 can be achieved.

[0111] It can be seen that by providing the third driving member 25, on the one hand, in addition to driving the pressing member 32 to move in a first direction toward the third flattening member 23 by the first driving member 31 to achieve the purpose of flattening the cell D on the second flattening member 22, the third driving member 25 can also drive the third flattening member 23 to move in a first direction toward the second flattening member 22 to achieve the purpose of flattening the cell D on the second flattening member 22. That is, the cell D on the second flattening member 22 can be subjected to a double flattening effect, and the flattening effect is better. On the other hand, the third driving member 25 can drive the third flattening member 23 to move in the first direction away from the second flattening member 22, so that the gap between the third flattening member 23 and the second flattening member 22 in the first direction is increased, which is conducive to placing the cell D on the surface of the second flattening member 22 facing the third flattening member 23, making it relatively simple to place the cell D on the surface of the second flattening member 22 facing the third flattening member 23.

[0112] It should be noted that the above-mentioned third driving member 25 can be a cylinder or an electric cylinder or any other structure capable of driving the third flattening member 23 to move in a first direction toward or away from the second flattening member 22, and this embodiment does not limit this.

[0113] The number of the above-mentioned third driving members 25 can be one. Of course, the number of the third driving members 25 can also be multiple, and this embodiment does not limit this.

[0114] In some embodiments, refer to Figure 4 , Figure 4FIG. 0 is a schematic structural diagram of another cell blanking and pressing device 100 for a winding device provided in an embodiment of the present application. The cell blanking and pressing device 100 for a winding device further includes a heightening assembly 4. The heightening assembly 4 includes a fourth driving member 41 and a heightening member 42. The fourth driving member 41 is disposed on the third flattening member 23, and the heightening member 42 is connected to the fourth driving member 41. The fourth driving member 41 is configured to drive the heightening member 42 to move between the third flattening member 23 and the driving assembly 3 or move away from between the third flattening member 23 and the driving assembly 3. Specifically, the fourth driving member 41 can drive the heightening member 42 to move between the third flattening member 23 and the pressing member 32 or move away from between the third flattening member 23 and the pressing member 32.

[0115] Since the fourth driving member 41 is disposed on the third flattening member 23 and the heightening member 42 is connected to the fourth driving member 41, the fourth driving member 41 can drive the heightening member 42 to move between the third flattening member 23 and the pressing member 32 or move away from between the third flattening member 23 and the pressing member 32.

[0116] Specifically, when it is necessary to drive the pressing member 32 to move in the first direction toward the third flattening member 23 by the first driving member 31 to push the third flattening member 23 to move in the first direction toward the second flattening member 22, so as to achieve the purpose of flattening the cell D. When the fourth driving member 41 drives the heightening member 42 to move between the third flattening member 23 and the pressing member 32, the first driving member 31 only needs to drive the pressing member 32 to move to a position where it abuts against the heightening member 42, and then the driving force of the pressing member 32 can be transmitted to the third flattening member 23 through the heightening member 42, and thus the purpose of flattening the cell D can be achieved.

[0117] That is to say, when the fourth driving member 41 drives the heightening member 42 to move between the third flattening member 23 and the pressing member 32, when it is necessary to achieve the purpose of flattening the cell D, the first driving member 31 does not need to drive the pressing member 32 to move too far in the first direction toward the third flattening member 23. Specifically, it does not need to move to a position where it abuts against the third flattening member 23, but only needs to move to a position where it abuts against the heightening member 42 to achieve the purpose of flattening the cell D. In this way, the stroke of the pressing member 32 in the first direction can be shortened to a certain extent, and then the time taken for the pressing member 32 to move in the first direction can be shortened, thereby further improving the flattening efficiency of the cell blanking and pressing device 100 for a winding device.

[0118] Wherein, the above-mentioned heightening member 42 can be in a plate shape or any other arbitrary shape structure, and this embodiment does not limit this. The above-mentioned fourth driving member 41 can be a cylinder, an electric cylinder or any other possible structure, as long as it can drive the heightening member 42 to move between the third flattening member 23 and the pressing member 32 or move away from between the third flattening member 23 and the pressing member 32, and this embodiment does not limit this.

[0119] In order to facilitate the placement of the battery cell D on the surface of the first flattening member 21 facing the second flattening member 22, in some embodiments, refer to Figure 4 , a first conveyor belt 211 is sleeved on the first flattening member 21, and a part of the belt body of the first conveyor belt 211 is attached to the surface of the first flattening member 21 facing the second flattening member 22.

[0120] Since the first conveyor belt 211 is sleeved on the first flattening member 21 and a part of the belt body of the first conveyor belt 211 is attached to the surface of the first flattening member 21 facing the second flattening member 22, when it is necessary to place the battery cell D on the surface of the first flattening member 21 facing the second flattening member 22, the battery cell D can be first placed on the first conveyor belt 211, and then the first conveyor belt 211 can be started to run. When the first conveyor belt 211 starts to run, the battery cell D can be conveyed to the surface of the first flattening member 21 facing the second flattening member 22, thereby achieving the purpose of placing the battery cell D on the surface of the first flattening member 21 facing the second flattening member 22. It is very convenient, with a high degree of automation, and can reduce the labor intensity of personnel.

[0121] When the first conveyor belt 211 is sleeved on the first flattening member 21, under the action of the first conveyor belt 211, the battery cell D can be placed on the surface of the first flattening member 21 facing the second flattening member 22 by means of conveying. Compared with the method of placing the battery cell D on the surface of the first flattening member 21 facing the second flattening member 22 by clamping with a clamping jaw, on the one hand, the situation of the clamping jaw scratching the battery cell D can be avoided, and on the other hand, the first conveyor belt 211 is more suitable for conveying the battery cell D that has not been completely flattened compared with the clamping jaw.

[0122] Similarly, in order to facilitate the placement of the battery cell D on the surface of the second flattening member 22 facing the third flattening member 23, in some embodiments, refer to Figure 4 , a second conveyor belt 221 is sleeved on the second flattening member 22, and a part of the belt body of the second conveyor belt 221 is attached to the surface of the second flattening member 22 facing the third flattening member 23.

[0123] Since the second conveyor belt 221 is sleeved on the second flattening member 22, and a part of the belt body of the second conveyor belt 221 is attached to the surface of the second flattening member 22 facing the third flattening member 23, when it is necessary to place the battery cell D on the surface of the second flattening member 22 facing the third flattening member 23, the battery cell D can be first placed on the second conveyor belt 221, and then, the second conveyor belt 221 can be started to convey. When the second conveyor belt 221 starts to convey, the battery cell D can be conveyed to the surface of the second flattening member 22 facing the third flattening member 23, thereby achieving the purpose of placing the battery cell D on the surface of the second flattening member 22 facing the third flattening member 23. It is very convenient, with a high degree of automation, and can reduce the labor intensity of personnel.

[0124] In some embodiments, referring to Figure 4 and Figure 5 , Figure 5 is Figure 4 a partial cross-sectional view of a part of the battery cell blanking and pressing device 100 for a winding device in Figure 5 along the X-axis view. The flattening assembly 2 further includes a fourth flattening member 26. The fourth flattening member 26 is disposed on the side of the second flattening member 22 facing the first flattening member 21 (

[0125] the lower side of the second flattening member 22 in Figure 4 ), and a belt-passing slit 20 is formed between the fourth flattening member 26 and the second flattening member 22. At least a part of the belt body of the second conveyor belt 221 facing the first flattening member 21 passes through the belt-passing slit 20.

[0126] In some embodiments, the conveying directions ( Figure 4 the X-axis direction in of the first conveyor belt 211 and the second conveyor belt 221 are both the second direction, and the second direction is perpendicular to the first direction.

[0127] By making the conveying directions of the first conveyor belt 211 and the second conveyor belt 221 the same, on the one hand, the layout between the first conveyor belt 211 and the second conveyor belt 221 can be made more regular, which is convenient for the layout of the first conveyor belt 211 and the second conveyor belt 221. On the other hand, it can also make the conveying direction of the battery cell D on the first conveyor belt 211 the same as the conveying direction of the battery cell D on the second conveyor belt 221, thereby making the feeding of the battery cell D more regular and simple.

[0128] In addition, by making the second direction perpendicular to the first direction, when the first direction is the vertical direction, the second direction can be the horizontal direction. In this way, the conveying of the battery cell D on the first conveyor belt 211 and the second conveyor belt 221 can be made more stable.

[0129] In some embodiments, refer to Figure 6A , Figure 6A FIG. is a schematic structural diagram of another battery cell blanking and pressing device 100 for a winding device provided by an embodiment of the present application.

[0130] The battery cell blanking and pressing device 100 for a winding device further includes a feeding assembly 5. The feeding assembly 5 is located on one side of the first flattening member 21 or the second flattening member 22 and is used for feeding the first flattening member 21 and the second flattening member 22.

[0131] Specifically, refer to Figure 6A , the first conveyor belt 211 and the second conveyor belt 221 both have input ends 210 along the second direction. The feeding assembly 5 is located on one side where the input end 210 of the first conveyor belt 211 is located along the second direction ( Figure 6A the X-axis direction in Figure 6A the left side of the first conveyor belt 211 in Figure 6A the Z-axis direction in

[0132] Since the feeding assembly 5 is located on one side where the input end 210 of the first conveyor belt 211 is located along the second direction and the feeding conveyor belt 52 is arranged on the first moving assembly 51, when the first moving assembly 51 drives the feeding conveyor belt 52 to move along the first direction, the feeding conveyor belt 52 can be made to be docked with the input end 210 of the first conveyor belt 211 and the input end 210 of the second conveyor belt 221 respectively.

[0133] When the loading conveyor belt 52 is docked with the input end 210 of the first conveyor belt 211, with the battery cell D placed on the loading conveyor belt 52, the battery cell D can be conveyed to the first conveyor belt 211 by the rotation of the loading conveyor belt 52, thereby achieving the purpose of loading the battery cell D onto the first conveyor belt 211.

[0134] When the loading conveyor belt 52 is docked with the input end 210 of the second conveyor belt 221, with the battery cell D placed on the loading conveyor belt 52, the battery cell D can be conveyed to the second conveyor belt 221 by the rotation of the loading conveyor belt 52, thereby achieving the purpose of loading the battery cell D onto the second conveyor belt 221.

[0135] It can be seen that by making the first moving component 51 drive the loading conveyor belt 52 to move in the first direction, the same loading conveyor belt 52 can automatically load the battery cell D onto the first conveyor belt 211 and the second conveyor belt 221 respectively. On the one hand, it can make the work of loading the battery cell D onto the first conveyor belt 211 and the second conveyor belt 221 more automated. On the other hand, since there is no need to separately set up dedicated loading conveyor belts 52 for the first conveyor belt 211 and the second conveyor belt 221, the number of loading conveyor belts 52 can be saved, the structure of the loading component 5 can be simplified, and the cost of the loading component 5 can be reduced.

[0136] Among them, the structure of the above-mentioned loading conveyor belt 52 can be the same as or similar to the structure of the first conveyor belt 211 or the second conveyor belt 221, and this embodiment does not limit this.

[0137] The above-mentioned first moving component 51 can be a lead screw lifting module or any structure that can drive the loading conveyor belt 52 to reciprocate in the first direction, and this embodiment does not limit the structure of the first moving component 51 either.

[0138] In some embodiments, referring to Figure 6B , Figure 6B is a schematic structural diagram of another battery cell unloading and pressing device for a winding device provided by an embodiment of the present application. The loading component 5 includes multiple loading conveyor belts 52, and one loading conveyor belt 52 among the multiple loading conveyor belts 52 corresponds to the first flattening member 21 and each second flattening member 22 respectively.

[0139] Since one loading conveyor belt 52 among the multiple loading conveyor belts 52 corresponds to the first flattening member 21 and each second flattening member 22 respectively, that is, each first flattening member 21 corresponds to one loading conveyor belt 52, and each second flattening member 22 corresponds to one loading conveyor belt 52. In this way, it can be ensured that each first flattening member 21 and each second flattening member 22 each have a dedicated loading conveyor belt 52, thereby improving the loading efficiency.

[0140] In some embodiments, referring to Figure 6A , the battery cell blanking and pressing device 100 for a winding device further includes a blanking assembly 6. The blanking assembly 6 is located on the side opposite to the feeding assembly 5 with respect to the first flattening member 21 or the second flattening member 22, and is used for blanking the first flattening member 21 and the second flattening member 22.

[0141] Specifically, referring to Figure 6A , both the first conveyor belt 211 and the second conveyor belt 221 have an output end 220 along the second direction. The blanking assembly 6 is located on the side where the output end 220 of the first conveyor belt 211 is located along the second direction ( Figure 6A the X-axis direction in Figure 6A the right side of the first conveyor belt 211 in ). The blanking assembly 6 includes a second moving assembly 61 and a blanking conveyor belt 62. The blanking conveyor belt 62 is arranged on the second moving assembly 61, and the second moving assembly 61 is used to drive the blanking conveyor belt 62 to move along the first direction.

[0142] Since the blanking assembly 6 is located on the side where the output end 220 of the first conveyor belt 211 is located along the second direction, and the blanking conveyor belt 62 is arranged on the second moving assembly 61, when the second moving assembly 61 drives the blanking conveyor belt 62 to move along the first direction, the blanking conveyor belt 62 can be docked with the output end 220 of the first conveyor belt 211 and the output end 220 of the second conveyor belt 221 respectively.

[0143] When the blanking conveyor belt 62 is docked with the output end 220 of the first conveyor belt 211, in the case where the battery cell D is placed on the first conveyor belt 211, the battery cell D can be conveyed to the blanking conveyor belt 62 by the rotation of the first conveyor belt 211, and thus the purpose of blanking the battery cell D on the first conveyor belt 211 can be achieved.

[0144] When the blanking conveyor belt 62 is docked with the output end 220 of the second conveyor belt 221, in the case where the battery cell D is placed on the second conveyor belt 221, the battery cell D can be conveyed to the blanking conveyor belt 62 by the rotation of the second conveyor belt 221, and thus the purpose of blanking the battery cell D on the second conveyor belt 221 can be achieved.

[0145] It can be seen that by driving the blanking conveyor belt 62 to move along the first direction by the second moving assembly 61, the battery cell D on the first conveyor belt 211 and the second conveyor belt 221 can be automatically blanked by the same blanking conveyor belt 62. On the one hand, the blanking work for the battery cell D on the first conveyor belt 211 and the second conveyor belt 221 can be made more automated. On the other hand, since there is no need to separately provide a dedicated blanking conveyor belt 62 for the first conveyor belt 211 and the second conveyor belt 221, the number of blanking conveyor belts 62 can be saved, the structure of the blanking assembly 6 can be simplified, and the cost of the blanking assembly 6 can be reduced.

[0146] Among them, the structure of the second moving component 61 can be the same as or similar to that of the first moving component 51 described above. For details, reference can be made to the description of the first moving component 51 in the above embodiments, and details will not be repeated herein.

[0147] In some embodiments, referring to Figure 6B , the blanking component 6 includes a plurality of blanking conveyor belts 62, and one blanking conveyor belt 62 among the plurality of blanking conveyor belts 62 corresponds to each of the first flattening member 21 and each second flattening member 22.

[0148] Since one blanking conveyor belt 62 among the plurality of blanking conveyor belts 62 corresponds to each of the first flattening member 21 and each second flattening member 22 respectively, that is, each first flattening member 21 corresponds to one blanking conveyor belt 62, and each second flattening member 22 corresponds to one blanking conveyor belt 62. In this way, each first flattening member 21 and each second flattening member 22 can each have a dedicated blanking conveyor belt 62, thereby improving the blanking efficiency.

[0149] In some embodiments, referring to Figure 4 , the support frame 1 includes a guide rod 11 and a mounting member 12. Among them, the guide rod 11 extends along the first direction ( Figure 4 the Z-axis direction in Figure 4 ), the second flattening member 22 and the third flattening member 23 are slidably arranged on the guide rod 11 along the first direction, and the mounting member 12 is arranged on the guide rod 11 and on the side of the third flattening member 23 away from the second flattening member 22 (

[0150] the upper side of the third flattening member 23 in

[0151] ), and the first driving member 31 is arranged on the mounting member 12.

[0152] Among them, the above-mentioned mounting member 12 can be a mounting plate or other possible structures, and this embodiment does not limit this.

[0153] Since the second flattening member 22 and the third flattening member 23 are slidably arranged on the guide rod 11 along the first direction, therefore, under the guiding action of the guide rod 11, the second flattening member 22 and the third flattening member 23 can slide more smoothly along the first direction.

[0154] Figure 7It is a schematic structural diagram of a battery core winding device 200 provided by an embodiment of the present application. Refer to Figure 7 , the battery core winding device 200 includes a battery core blanking and pressing device 100 for the winding device.

[0155] Among them, the structure of the battery core blanking and pressing device 100 for the winding device can be the same as the structure of any of the battery core blanking and pressing devices 100 for the winding device in the above embodiments, and can bring the same or similar beneficial effects. Specifically, reference can be made to the description of the battery core blanking and pressing device 100 for the winding device in the above embodiments, and this embodiment will not be elaborated here.

[0156] In this embodiment, since the battery core blanking and pressing device 100 for the winding device can flatten multiple battery cores D at one time and keep the pressure on multiple battery cores D at one time, in this way, the efficiency of flattening the battery cores D by the battery core blanking and pressing device 100 for the winding device can be improved. Based on this, when the battery core blanking and pressing device 100 for the winding device is applied to the battery core winding device 200, the processing efficiency of the battery core winding device 200 can be improved.

[0157] In some embodiments, the battery core winding device 200 further includes a winding mechanism 201, a blanking mechanism 202, a conveying mechanism 203 and a pre-pressing mechanism 204. Among them, the winding mechanism 201 is used for winding the battery core D, the blanking mechanism 202 is used for blanking the battery core D to the conveying mechanism 203, the pre-pressing mechanism 204 is used for pre-pressing the battery core D on the conveying mechanism 203, and the conveying mechanism 203 is used for conveying the pre-pressed battery core D to the first flattening member 21 or the second flattening member 22.

[0158] In this embodiment, first, the winding mechanism 201 can wind the battery core D. Specifically, the winding mechanism 201 can include a winding needle, and the battery core D can be made when the winding needle rotates. Then, the blanking mechanism 202 can blank the battery core D on the winding needle to the conveying mechanism 203. After the battery core D is blanked to the conveying mechanism 203, the pre-pressing mechanism 204 can pre-press the battery core D on the conveying mechanism 203 so that the battery core D is preliminarily flattened.

[0159] After the battery core D is preliminarily flattened, that is, after the battery core D is pre-pressed, the conveying mechanism 203 can convey the preliminarily flattened battery core D to the first flattening member 21 or the second flattening member 22 for secondary flattening work and pressure holding.

[0160] When the battery core winding device 200 further includes a pre-pressing mechanism 204, since the pre-pressing mechanism 204 can preliminarily flatten the battery core D, it prepares for the secondary flattening at the first flattening member 21 or the second flattening member 22, and further makes the flattening effect of the battery core D produced by the battery core winding device 200 better.

[0161] When the battery cell winding device 200 further includes a blanking mechanism 202 and a conveying mechanism 203, the blanking mechanism 202 can automatically blank the battery cell D on the winding needle to the conveying mechanism 203, and the conveying mechanism 203 can automatically convey the preliminarily flattened battery cell D to the first flattening member 21 or the second flattening member 22. The whole process can be completed automatically without the participation of personnel. Therefore, the automation degree of the whole battery cell winding device 200 can be higher.

[0162] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
