Description

Technical Field

[0001] This application relates to the field of battery processing equipment technology, and in particular to a cell feeding and pressing device and a cell winding device for winding equipment. Background Technology

[0002] In the manufacturing process of battery cells, there is a step of flattening the cells. Specifically, the cells are typically flattened using a cell pressing device used in winding equipment. To ensure the flattening effect, the pressing device needs to hold the cells under pressure for a period of time after flattening. However, holding the pressure for the cells takes time, resulting in low flattening efficiency of the pressing device and consequently low processing efficiency of the battery cell winding equipment. Utility Model Content

[0003] This application discloses a cell feeding and pressing device and a cell winding equipment for a winding machine, which has a high flattening efficiency, thereby making the processing efficiency of the cell winding equipment high.

[0004] To achieve the above objectives, in a first aspect, this application discloses a battery cell feeding and pressing device for a winding equipment, comprising:

[0005] A flattening assembly, comprising a first flattening member, a second flattening member, and a third flattening member, wherein the first flattening member, the second flattening member, and the third flattening member are stacked at intervals along a first direction, and the second flattening member and the third flattening member are slidably disposed along the first direction; and,

[0006] A driving assembly is located on the side of the third flattening member opposite to the second flattening member, and at least one second flattening member is disposed between the first flattening member and the third flattening member.

[0007] Since the first, second, and third flattened parts are stacked at intervals along the first direction, and the second and third flattened parts are slidably arranged along the first direction, and since the driving assembly is located on the side of the third flattened part away from the second flattened part, when battery cells are placed on both the side of the first flattened part facing the second flattened part and the side of the second flattened part facing the third flattened part, when the driving assembly drives the third flattened part to move closer to the second flattened part, the battery cells on the second flattened part are clamped between the third flattened part and the second flattened part. The driving assembly can also drive the second flattened part to move along the first direction closer to the first flattened part, so that the battery cells on the first flattened part are clamped between the first flattened part and the second flattened part.

[0008] Furthermore, when the battery cell on the second flattening member is clamped between the third flattening member and the second flattening member, and when the battery cell on the first flattening member is clamped between the first flattening member and the second flattening member, by keeping the driving component stationary, the battery cells on the second flattening member and the battery cells on the first flattening member can be continuously subjected to clamping force, forming a pressure-holding effect, thereby enabling both the battery cells on the second flattening member and the battery cells on the first flattening member to be well flattened.

[0009] Therefore, when the driving component drives the third flattening member to move, the battery cell on the first flattening member is clamped between the first flattening member and the second flattening member, thus flattening the battery cell on the first flattening member. At the same time, the battery cell on the second flattening member is also clamped between the third flattening member and the second flattening member, thus flattening the battery cell on the second flattening member. Furthermore, when the battery cell on the first flattening member is clamped between the first flattening member and the second flattening member, and when 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 battery cells on the first flattening member can be continuously subjected to clamping force, forming a pressure-holding effect.

[0010] In other words, this cell feeding and pressing device for winding equipment can simultaneously flatten the cells on the first flattening member and the second flattening member, and can also simultaneously maintain pressure on the cells on the first and second flattening members. Simply put, this cell feeding and pressing device for winding equipment can flatten multiple cells at once and maintain pressure on multiple cells at once, thus improving the efficiency of flattening the cells. Therefore, when this cell feeding and pressing device for winding equipment is applied to cell winding equipment, it can improve the processing efficiency of the cell winding equipment.

[0011] Optionally, the driving component includes:

[0012] The first driving component; and,

[0013] A clamping member, which is connected to the first driving member and located on the side of the third flattening member opposite to the second flattening member.

[0014] Optionally, the flattening assembly further includes:

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

[0016] By providing a second driving member, on the one hand, in addition to using the first driving member to drive the clamping member to move along the first direction towards the third flattening member to flatten the battery cell on the first flattening member, the second driving member can also drive the second flattening member to move along the first direction towards the first flattening member to flatten the battery cell on the first flattening member. That is, the battery cell on the first flattening member can be subjected to a double flattening effect, resulting in a better flattening effect. On the other hand, the second driving member can drive the second flattening member to move along the first direction away from the first flattening member, increasing the gap between the second and first flattening members along the first direction. This facilitates placing the battery cell on the side of the first flattening member facing the second flattening member, making the placement of the battery cell on the side of the first flattening member facing the second flattening member simpler.

[0017] Optionally, the flattening assembly further includes:

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

[0019] By incorporating a third driving component, on the one hand, in addition to using the first driving component to drive the clamping component to move towards the third flattening component along the first direction to flatten the battery cell on the second flattening component, the third driving component can also drive the third flattening component to move towards the second flattening component along the first direction to flatten the battery cell on the second flattening component. That is, the battery cell on the second flattening component can undergo a double flattening effect, resulting in a better flattening effect. On the other hand, the third driving component can drive the third flattening component to move away from the second flattening component along the first direction, increasing the gap between the third and second flattening components along the first direction. This facilitates placing the battery cell on the side of the second flattening component facing the third flattening component, making the placement of the battery cell on the side of the second flattening component facing the third flattening component simpler.

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

[0021] A shim assembly, comprising a fourth driving member and a shim, wherein the fourth driving member is disposed on the third flattening member, and the shim is connected to the fourth driving member, and the fourth driving member is used to drive the shim to move between the third flattening member and the driving assembly or to move away from the third flattening member and the driving assembly.

[0022] In this way, the travel of the clamping member along the first direction can be shortened to a certain extent, thereby shortening the time spent by the clamping member moving along the first direction, and thus further improving the flattening efficiency of the cell feeding and pressing device used in the winding equipment.

[0023] Optionally, a first conveyor belt is fitted onto the first flattening member, and a portion of the first conveyor belt is attached to the side of the first flattening member facing the second flattening member.

[0024] Since the first conveyor belt is fitted onto the first flattening member, and part of the first conveyor belt is attached to the side of the first flattening member facing the second flattening member, when it is necessary to place the battery cell on the side of the first flattening member facing the second flattening member, the battery cell can be placed on the first conveyor belt first, and then the first conveyor belt can be started to convey the battery cell to the side of the first flattening member facing the second flattening member when the first conveyor belt starts to convey the battery cell. This achieves the purpose of placing the battery cell on the side of the first flattening member facing the second flattening member, which is very convenient, has a high degree of automation, and can reduce the labor intensity of personnel.

[0025] Optionally, a second conveyor belt is fitted onto the second flattening member, and a portion of the second conveyor belt is attached to the side of the second flattening member facing the third flattening member.

[0026] Since the second conveyor belt is fitted onto the second flattening member, and part of the second conveyor belt is in contact with the side of the second flattening member facing the third flattening member, when it is necessary to place the battery cell on the side of the second flattening member facing the third flattening member, the battery cell can be placed on the second conveyor belt first, and then the second conveyor belt can be started to convey the battery cell to the side of the second flattening member facing the third flattening member when the second conveyor belt starts to convey the battery cell. This achieves the purpose of placing the battery cell on the side of the second flattening member facing the third flattening member, which is very convenient, has 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 is disposed on the side of the second flattening member facing the first flattening member, and a threading seam is formed between the fourth flattening member and the second flattening member, wherein at least a portion of the second conveyor belt facing the first flattening member passes through the threading seam.

[0029] Since the fourth flattening member is located on the side of the second flattening member facing the first flattening member, a threading seam is formed between the fourth flattening member and the second flattening member. At least a portion of the second conveyor belt facing the first flattening member is threaded through the threading seam. Therefore, the fourth flattening member can partially 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 towards the third flattening member in the first direction, the battery cell on the first flattening member can be clamped between the fourth flattening member and the first flattening member. That is, the fourth flattening member can replace the second flattening member and the first flattening member to clamp the battery cell on the first flattening member. This can avoid the interference between the second conveyor belt and the battery cell on the first flattening member, so that the battery cell on the first flattening member can be well flattened by the fourth flattening member and the first flattening member.

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

[0031] By aligning the first and second conveyor belts in the same direction, two things are achieved: firstly, their layout becomes more organized and easier to arrange; secondly, the direction in which the first and second conveyor belts transport the battery cells is the same, making the loading of the battery cells more standardized and simpler.

[0032] In addition, by making the second direction perpendicular to the first direction, when the first direction is vertical, the second direction can be horizontal. This makes the transmission of the battery cells on the first and second conveyor belts more stable.

[0033] Optionally, it also includes a feeding assembly located on one side of the first flattened part or the second flattened part, for feeding the first flattened part and the second flattened part.

[0034] Optionally, the feeding assembly includes:

[0035] The first moving component; and,

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

[0037] Optionally, the feeding assembly includes:

[0038] Multiple feeding conveyor belts are provided, and the first flattening component and each of the second flattening components are respectively provided with one of the multiple feeding conveyor belts.

[0039] Optionally, the cell feeding and pressing device for the winding equipment further includes a feeding assembly, which is located on the side opposite to the feeding assembly of the first flattened piece or the second flattened piece, and is used to feed the first flattened piece and the second flattened piece.

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

[0041] By causing the second moving component to drive the unloading conveyor belt to move along the first direction, the same unloading conveyor belt can automatically unload the battery cells on the first and second conveyor belts respectively. On the one hand, this makes the unloading of battery cells on the first and second conveyor belts more automated. On the other hand, since there is no need to set up separate unloading conveyor belts for the first and second conveyor belts, 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 feeding assembly includes:

[0043] Multiple feeding conveyor belts are provided, and each of the first flattened part and each of the second flattened parts is correspondingly provided with one of the multiple feeding conveyor belts.

[0044] Optionally, it also includes a support frame, the support frame comprising:

[0045] A guide rod extends 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] The mounting component is disposed on the guide rod and located on the side of the third flattening member opposite to the second flattening member, and the drive assembly is disposed on the mounting component.

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

[0048] Secondly, this application discloses a battery cell winding device, including the battery cell feeding and pressing device for winding devices described in any of the first aspects above.

[0049] Because the cell feeding and pressing device used in winding equipment can flatten multiple cells at once and maintain pressure on multiple cells simultaneously, the efficiency of flattening the cells can be improved. Therefore, when this cell feeding and pressing device is applied to cell winding equipment, the processing efficiency of the cell winding equipment can be increased.

[0050] Optionally, it also includes:

[0051] A winding mechanism for winding battery cells;

[0052] Feeding mechanism;

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

[0054] A 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 equipment also includes a pre-pressing mechanism, the pre-pressing mechanism can initially flatten the battery cell, preparing it for subsequent secondary flattening at the first or second flattening part, thus making the battery cell flattening effect produced by the battery cell winding equipment better.

[0056] When the battery cell winding equipment also includes a feeding mechanism and a conveying mechanism, the feeding mechanism can automatically feed the battery cells from the winding needles to the conveying mechanism, and the conveying mechanism can automatically convey the initially flattened battery cells to the first flattening part or the second flattening part. The whole process can be completed automatically without human intervention, thus making the automation level of the entire battery cell winding equipment higher.

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

[0058] In this application, since the first flattened member, the second flattened member, and the third flattened member are stacked at intervals along the first direction, and the second flattened member and the third flattened member are slidably disposed along the first direction, and since the driving component is located on the side of the third flattened member away from the second flattened member, when battery cells are placed on both the side of the first flattened member facing the second flattened member and the side of the second flattened member facing the third flattened member, when the driving component drives the third flattened member to move towards the second flattened member, the battery cells on the second flattened member are clamped between the third flattened member and the second flattened member. The driving component can also drive the second flattened member to move along the first direction towards the first flattened member, so that the battery cells on the first flattened member are clamped between the first flattened member and the second flattened member.

[0059] Therefore, when the driving component drives the third flattening member to move, the battery cell on the first flattening member is clamped between the first flattening member and the second flattening member, thus flattening the battery cell on the first flattening member. At the same time, the battery cell on the second flattening member is also clamped between the third flattening member and the second flattening member, thus flattening the battery cell on the second flattening member. Furthermore, when the battery cell on the first flattening member is clamped between the first flattening member and the second flattening member, and when 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 battery cells on the first flattening member can be continuously subjected to clamping force, forming a pressure-holding effect.

[0060] In other words, this cell feeding and pressing device for winding equipment can simultaneously flatten the cells on the first flattening member and the second flattening member, and can also simultaneously maintain pressure on the cells on the first and second flattening members. Simply put, this cell feeding and pressing device for winding equipment can flatten multiple cells at once and maintain pressure on multiple cells at once, thus improving the efficiency of flattening the cells. Therefore, when this cell feeding and pressing device for winding equipment is applied to cell winding equipment, it can improve the processing efficiency of the cell winding equipment.

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

[0086] In the manufacturing process of battery cells, there is a step of flattening the cells. Specifically, the cells are typically flattened using a cell blanking and pressing device used in winding equipment. To ensure the flattening effect, the cell blanking and pressing device needs to hold the cells under pressure for a period of time after flattening. However, holding the cells under pressure takes time, resulting in low flattening efficiency of the cell blanking and pressing device used in winding equipment, and consequently, low processing efficiency of the battery cell winding equipment. Therefore, this application provides a new cell blanking and pressing device for winding equipment to solve the above problems.

[0087] The technical solution of this application will be described below with reference to specific embodiments and accompanying drawings.

[0088] Figure 1 This is a schematic diagram of the structure of a cell feeding and pressing device 100 for a winding equipment according to an embodiment of this application. See also... Figure 1 The cell feeding and pressing device 100 for winding equipment includes a support frame 1, a flattening assembly 2, and a drive assembly 3. The flattening assembly 2 includes a first flattening member 21, a second flattening member 22, and a third flattening member 23. The first flattening member 21, the second flattening member 22, and the third flattening member 23 are aligned along a first direction (…). Figure 1 The components are stacked at intervals along the Z-axis direction, and 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 drive assembly 3 is located on the side of the third flattening member 23 that is 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 drive assembly 3 includes a first drive member 31 and a clamping member 32. The first drive member 31 is disposed on the support frame 1, and the clamping member 32 is connected to the first drive member 31 and is located on the side of the third flattening member 23 opposite to the second flattening member 22. Figure 1 The upper side of the third flattening member 23), the first driving member 31 is used to drive the clamping member 32 towards (the upper side of the third flattening member 23) along the first direction. Figure 1 (negative direction of the Z-axis) or away from ( Figure 1 (Positive direction of the Z-axis) The third flattening part 23 moves.

[0091] In this embodiment, when the battery cell D is flattened by the battery cell feeding and pressing device 100 for the winding equipment, the first flattening member 21, the second flattening member 22, and the third flattening member 23 move along the first direction ( Figure 1 The layers are stacked at intervals along the Z-axis, so the first flattened member 21 can be placed on the side facing the second flattened member 22. Figure 1 The upper surface of the first flattening member 21 and the side of the second flattening member 22 facing the third flattening member 23. Figure 1 Battery cells D are placed on the upper surface of the second flattened member 22. Then, since the second flattened member 22 and the third flattened member 23 are slidably arranged along the first direction, specifically, the second flattened member 22 and the third flattened member 23 can be slidably arranged on the support frame 1 along the first direction. Since the driving component 3 is located on the side of the third flattened member 23 away from the second flattened member 22, specifically, the first driving component 31 is arranged on the support frame 1, and the clamping component 32 is connected to the first driving component 31 and located on the side of the third flattened member 23 away from the second flattened member 22, the first driving component 31 can drive the clamping component 32 to move along the first direction toward the third flattened member 23.

[0092] As the first driving member 31 drives the clamping member 32 to move towards the third flattening member 23 in the first direction ( Figure 1 Moving along the negative Z-axis, the clamping member 32 can move until it contacts the third flattening member 23. When the clamping member 32 is in contact with the third flattening member 23, when the first driving member 31 drives the clamping member 32 to continue moving towards the third flattening member 23 along the first direction, the clamping member 32 can push the third flattening member 23 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, thereby flattening the battery cell D on the second flattening member 22.

[0093] Simultaneously, when the battery cell D on the second flattened member 22 is clamped between the third flattened member 23 and the second flattened member 22, the power of the drive assembly 3, specifically the power of the clamping member 32, can also be transmitted to the second flattened member 22 through the battery cell D on the third flattened member 23 and the second flattened member 22. This allows the second flattened member 22 to move closer to the first flattened member 21 along the first direction, thereby clamping the battery cell D on the first flattened member 21 between the first flattened member 21 and the second flattened member 22. When the battery cell D on the first flattened member 21 is clamped between the first flattened member 21 and the second flattened member 22, the battery cell D on the first flattened 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, the battery cell D on the second flattening member 22 is flattened. 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 is also flattened, the clamping 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 be continuously subjected to clamping force, forming a pressure-holding effect, thereby enabling the battery cell D on the second flattening member 22 and the battery cell D on the first flattening member 21 to be flattened well.

[0095] As can be seen, since the first flattened member 21, the second flattened member 22, and the third flattened member 23 are stacked at intervals along the first direction, and the second flattened member 22 and the third flattened member 23 are slidably arranged along the first direction, and since the driving component 3 is located on the side of the third flattened member 23 away from the second flattened member 22, when the battery cell D is placed on both the side of the first flattened member 21 facing the second flattened member 22 and the side of the second flattened member 22 facing the third flattened member 23, when the driving component 3 drives the third flattened member 23 to move towards the direction closer to the second flattened member 22, the battery cell D on the second flattened member 22 is clamped between the third flattened member 23 and the second flattened member 22. The driving component 3 can also drive the second flattened member 22 to move along the first direction towards the direction closer to the first flattened member 21, so that the battery cell D on the first flattened member 21 is clamped between the first flattened member 21 and the second flattened member 22.

[0096] Furthermore, 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, and 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, by keeping the driving component 3 stationary, the battery cell D on the second flattening member 22 and the battery cell D on the first flattening member 21 can be continuously subjected to clamping force, forming a pressure-holding effect, thereby enabling the battery cell D on the second flattening member 22 and the battery cell D on the first flattening member 21 to be well flattened.

[0097] Therefore, when the driving component 3 drives the third flattening member 23 to move, the battery cell D on the first flattening member 21 is clamped between the first flattening member 21 and the second flattening member 22, thereby flattening the battery cell D on the first flattening member 21. At the same time, the battery cell D on the second flattening member 22 is also clamped between the third flattening member 23 and the second flattening member 22, thereby flattening the battery cell D on the second flattening member 22. Furthermore, 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, and the battery cell D on the second flattening member 22 is clamped between the third flattening member 23 and the second flattening member 22, by keeping the driving component 3 stationary, the battery cell D on the second flattening member 22 and the battery cell D on the first flattening member 21 can be continuously subjected to clamping force, forming a pressure-holding effect.

[0098] In other words, the cell feeding and pressing device 100 for the winding equipment can simultaneously flatten the cells D on the first flattening member 21 and the second flattening member 22, and can also simultaneously hold the cells D on the first flattening member 21 and the second flattening member 22 under pressure. In simpler terms, the cell feeding and pressing device 100 for the winding equipment can flatten multiple cells D at once and hold multiple cells D under pressure at once, thus improving the efficiency of flattening the cells D. Therefore, when the cell feeding and pressing device 100 for the winding equipment is applied to the cell winding equipment 200, the processing efficiency of the cell winding equipment 200 can be improved.

[0099] The first flattening component 21, the second flattening component 22 and the third flattening component 23 can all be hot press plates or other components that can flatten the battery cell D. This embodiment does not limit this.

[0100] The first direction mentioned above can be vertical or approximately vertical. When the first direction is vertical, the side of the first flattened member 21 facing the second flattened member 22 and the side of the second flattened member 22 facing the third flattened member 23 can be horizontal. In this way, the battery cell D placed on the side of the first flattened member 21 facing the second flattened member 22 and the side of the second flattened member 22 facing the third flattened member 23 can be more stable and less likely to fall off.

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

[0102] It should be noted that the number of the second flattening member 22 mentioned above can be one, two, three or four, etc., and this embodiment does not limit this.

[0103] When there are multiple second flattening parts 22, if a battery cell D is placed between two adjacent second flattening parts 22, the battery cell D between the two adjacent second flattening parts 22 can be clamped between the two second flattening parts 22 and flattened.

[0104] In some embodiments, see Figure 2 , Figure 2 This is a schematic diagram of another battery cell feeding and pressing device 100 for a winding equipment provided in an embodiment of this application. The flattening assembly 2 further includes a second driving member 24, which 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 a first direction ( Figure 2 (In the Z-axis direction) it moves toward or away from the first flattened part 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 towards or away from the first flattening member 21 along the first direction. When the second driving member 24 drives the second flattening member 22 to move away from the first flattening member 21 along the first direction, the gap between the second flattening member 22 and the first flattening member 21 along the first direction can be increased, which is beneficial for placing the battery cell D on the side 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 along the first direction, the battery cell D can be clamped between the first flattening member 21 and the second flattening member 22, thereby achieving the purpose of flattening the battery cell D on the first flattening member 21.

[0106] As can be seen, by setting the second driving member 24, on the one hand, in addition to driving the pressing member 32 along the first direction towards the third flattening member 23 through the first driving member 31 to flatten the battery cell D on the first flattening member 21, the second driving member 24 can also drive the second flattening member 22 along the first direction towards the first flattening member 21 to flatten the battery cell D on the first flattening member 21. That is, the battery cell D on the first flattening member 21 can be subjected to a double flattening effect, resulting in a better flattening effect. On the other hand, the second driving member 24 can drive the second flattening member 22 along the first direction away from the first flattening member 21, making the gap between the second flattening member 22 and the first flattening member 21 along the first direction larger. This facilitates placing the battery cell D on the side of the first flattening member 21 facing the second flattening member 22, making it simpler to place the battery cell D on the side of the first flattening member 21 facing the second flattening member 22.

[0107] It should be noted that the 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 closer to or further away from the first flattening member 21 along the first direction. This embodiment does not limit this.

[0108] The number of the second driving element 24 can be one, or it can be multiple. This embodiment does not limit this.

[0109] Furthermore, in some embodiments, see Figure 3 , Figure 3This is a schematic diagram of the structure of another battery cell feeding and pressing device 100 for winding equipment provided in an embodiment of this application. The flattening component 2 also 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 used to drive the third flattening member 23 to move along the 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 towards or away from the second flattening member 22 along the first direction. When the third driving member 25 drives the third flattening member 23 to move away from the second flattening member 22 along the first direction, the gap between the third flattening member 23 and the second flattening member 22 along the first direction can be increased, which is beneficial for placing the battery cell D on the side 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 towards the second flattening member 22 along the first direction, the battery cell D can be clamped between the third flattening member 23 and the second flattening member 22, thereby achieving the purpose of flattening the battery cell D on the second flattening member 22.

[0111] As can be seen, by setting the third driving member 25, on the one hand, in addition to driving the clamping member 32 along the first direction towards the third flattening member 23 through the first driving member 31 to flatten the battery cell D on the second flattening member 22, the third driving member 25 can also drive the third flattening member 23 along the first direction towards the second flattening member 22 to flatten the battery cell D on the second flattening member 22. That is, the battery cell D on the second flattening member 22 can be subjected to a double flattening effect, resulting in a better flattening effect. On the other hand, the third driving member 25 can drive the third flattening member 23 along the first direction away from the second flattening member 22, thereby increasing the gap between the third flattening member 23 and the second flattening member 22 along the first direction. This facilitates placing the battery cell D on the side of the second flattening member 22 facing the third flattening member 23, making it simpler to place the battery cell D on the side of the second flattening member 22 facing the third flattening member 23.

[0112] It should be noted that the aforementioned third driving component 25 can be any structure, such as a cylinder or an electric cylinder, capable of driving the third flattening component 23 to move towards or away from the second flattening component 22 along the first direction. This embodiment does not limit this.

[0113] The number of the aforementioned third driving component 25 can be one, or of course, multiple. This embodiment does not limit this.

[0114] In some embodiments, see Figure 4 , Figure 4This is a schematic diagram of the structure of another battery cell feeding and pressing device 100 for a winding equipment provided in an embodiment of this application. The battery cell feeding and pressing device 100 for a winding equipment also includes a padding component 4. The padding component 4 includes a fourth driving member 41 and a padding member 42. The fourth driving member 41 is disposed on the third flattening member 23, and the padding member 42 is connected to the fourth driving member 41. The fourth driving member 41 is used to drive the padding member 42 to move between the third flattening member 23 and the driving component 3 or to move away from the third flattening member 23 and the driving component 3. Specifically, the fourth driving member 41 can drive the padding member 42 to move between the third flattening member 23 and the pressing member 32 or to move away from 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 shim 42 is connected to the fourth driving member 41, the fourth driving member 41 can drive the shim 42 to move between the third flattening member 23 and the clamping member 32 or to move away from the third flattening member 23 and the clamping member 32.

[0116] Specifically, when it is necessary to drive the clamping member 32 to move along the first direction toward the third flattening member 23 through the first driving member 31, so as to push the third flattening member 23 to move along the first direction toward the second flattening member 22, thereby achieving the purpose of flattening the battery cell D, when the fourth driving member 41 drives the raising member 42 to move between the third flattening member 23 and the clamping member 32, the first driving member 31 only needs to drive the clamping member 32 to move to the position of abutting against the raising member 42, so that the pushing force of the clamping member 32 can be transmitted to the third flattening member 23 through the raising member 42, thereby achieving the purpose of flattening the battery cell D.

[0117] In other words, when the fourth driving member 41 drives the raising member 42 to move between the third flattening member 23 and the clamping member 32, when the purpose of flattening the battery cell D needs to be achieved, the first driving member 31 does not need to drive the clamping member 32 to move too far along the first direction towards the third flattening member 23. Specifically, it does not need to move to the position of abutting against the third flattening member 23, but only to the position of abutting against the raising member 42 to achieve the purpose of flattening the battery cell D. In this way, the stroke of the clamping member 32 along the first direction can be shortened to a certain extent, thereby shortening the time spent by the clamping member 32 moving along the first direction, and thus further improving the flattening efficiency of the battery cell feeding and pressing device 100 used for winding equipment.

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

[0119] In order to facilitate the placement of the battery cell D on the side of the first flattening member 21 facing the second flattening member 22, in some embodiments, see... Figure 4 A first conveyor belt 211 is fitted onto the first flattening member 21, and a portion of the first conveyor belt 211 is attached to the side of the first flattening member 21 facing the second flattening member 22.

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

[0121] When the first flattening member 21 is fitted with the first conveyor belt 211, the battery cell D can be placed on the side of the first flattening member 21 facing the second flattening member 22 by conveying under the action of the first conveyor belt 211. Compared with the method of placing the battery cell D on the side of the first flattening member 21 facing the second flattening member 22 by clamping, on the one hand, it can avoid the situation of the clamping claw damaging the battery cell D. On the other hand, the first conveyor belt 211 is more suitable for conveying the battery cell D that has not been completely flattened than the clamping claw.

[0122] Similarly, in order to facilitate the placement of the battery cell D on the side of the second flattening member 22 facing the third flattening member 23, in some embodiments, see [reference needed]. Figure 4 A second conveyor belt 221 is fitted onto the second flattening member 22, and a portion of the second conveyor belt 221 is attached to the side of the second flattening member 22 facing the third flattening member 23.

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

[0124] In some embodiments, see Figure 4 and Figure 5 , Figure 5 yes Figure 4 A partial cross-sectional view of the cell feeding and pressing device 100 for the winding equipment along the X-axis shows that the flattening assembly 2 also includes a fourth flattening member 26, which is disposed on the side of the second flattening member 22 facing the first flattening member 21. Figure 5 (Under the second flattening member 22), a threading seam 20 is formed between the fourth flattening member 26 and the second flattening member 22, and at least a portion of the second conveyor belt 221 is threaded through the threading seam 20 toward the first flattening member 21.

[0125] Since the fourth flattening member 26 is disposed on the side of the second flattening member 22 facing the first flattening member 21, a threading slot 20 is formed between the fourth flattening member 26 and the second flattening member 22. At least a portion of the second conveyor belt 221 facing the first flattening member 21 passes through the threading slot 20. Therefore, the fourth flattening member 26 can partially wrap the second conveyor belt 221 on the side of the second flattening member 22 facing the first flattening member 21. In this way, when the first driving member 31 drives the pressing member 32 to move towards the third flattening member 23 in the first direction... Figure 4 When moving in the negative direction of the Z-axis, the battery cell D on the first flattening member 21 can be clamped between the fourth flattening member 26 and the first flattening member 21. That is, the fourth flattening member 26 can replace the second flattening member 22 and clamp the battery cell D on the first flattening member 21 together. This can avoid the interference between the second conveyor belt 221 and the battery cell D on the first flattening member 21, so that the battery cell D on the first flattening member 21 can be well flattened by the fourth flattening member 26 and the first flattening member 21.

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

[0127] By aligning the conveying directions of the first conveyor belt 211 and the second conveyor belt 221, on the one hand, the layout between the first conveyor belt 211 and the second conveyor belt 221 becomes more regular, facilitating their arrangement. On the other hand, it also ensures that the direction in which the first conveyor belt 211 conveys the battery cell D is the same as the direction in which the second conveyor belt 221 conveys the battery cell D, thereby making the feeding of the battery cell D more regular and simpler.

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

[0129] In some embodiments, see Figure 6A , Figure 6A This is a schematic diagram of another battery cell feeding and pressing device 100 for a winding equipment provided in an embodiment of this application.

[0130] The cell feeding and pressing device 100 for the winding equipment also includes a feeding component 5, which is located on one side of the first flattening member 21 or the second flattening member 22 and is used to feed the first flattening member 21 and the second flattening member 22.

[0131] Specifically, see Figure 6A Both the first conveyor belt 211 and the second conveyor belt 221 have input ends 210 along the second direction, and the feeding assembly 5 is along the second direction ( Figure 6A (in the X-axis direction) located on the side where the input end 210 of the first conveyor belt 211 is located ( Figure 6A The feeding assembly 5 includes a first moving assembly 51 and a feeding conveyor belt 52, located on the left side of the first moving assembly 51. The first moving assembly 51 is used to drive the feeding conveyor belt 52 along a first direction ( Figure 6A (Moves along the Z-axis).

[0132] Since the feeding component 5 is located on the side of the input end 210 of the first conveyor belt 211 along the second direction, and the feeding conveyor belt 52 is disposed on the first moving component 51, when the first moving component 51 drives the feeding conveyor belt 52 to move along the first direction, the feeding conveyor belt 52 can be connected to 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 feeding conveyor belt 52 is connected to the input end 210 of the first conveyor belt 211, and a battery cell D is placed on the feeding conveyor belt 52, the battery cell D can be transferred to the first conveyor belt 211 by the rotation of the feeding conveyor belt 52, thereby achieving the purpose of feeding the battery cell D to the first conveyor belt 211.

[0134] When the feeding conveyor belt 52 is connected to the input end 210 of the second conveyor belt 221, if a battery cell D is placed on the feeding conveyor belt 52, the battery cell D can be transferred to the second conveyor belt 221 by the rotation of the feeding conveyor belt 52, thereby achieving the purpose of feeding the battery cell D to the second conveyor belt 221.

[0135] As can be seen, by causing the first moving component 51 to drive the feeding conveyor belt 52 to move along the first direction, the same feeding conveyor belt 52 can automatically feed the battery cells D to the first conveyor belt 211 and the second conveyor belt 221 respectively. On the one hand, the operation of feeding the battery cells D to the first conveyor belt 211 and the second conveyor belt 221 can be more automated. On the other hand, since there is no need to set up separate feeding conveyor belts 52 for the first conveyor belt 211 and the second conveyor belt 221, the number of feeding conveyor belts 52 can be saved, the structure of the feeding component 5 can be simplified, and the cost of the feeding component 5 can be reduced.

[0136] The structure of the feeding conveyor belt 52 may be the same as or similar to that of the first conveyor belt 211 or the second conveyor belt 221, and this embodiment does not limit it.

[0137] The first moving component 51 can be a lead screw lifting module or any structure that can drive the feeding conveyor belt 52 to reciprocate along the first direction. In this embodiment, the structure of the first moving component 51 is not limited.

[0138] In some embodiments, see Figure 6B , Figure 6B This is a schematic diagram of the structure of another battery cell feeding and pressing device for winding equipment provided in an embodiment of this application. The feeding component 5 includes multiple feeding conveyor belts 52. The first flattening member 21 and each second flattening member 22 are respectively provided with one of the multiple feeding conveyor belts 52.

[0139] Since each of the first flattened parts 21 and each of the second flattened parts 22 is respectively provided with one of the multiple feeding conveyor belts 52, that is, each first flattened part 21 corresponds to one feeding conveyor belt 52 and each second flattened part 22 corresponds to one feeding conveyor belt 52, in this way, each first flattened part 21 and each second flattened part 22 can have its own dedicated feeding conveyor belt 52, thereby improving the feeding efficiency.

[0140] In some embodiments, see Figure 6A The cell feeding and pressing device 100 for the winding equipment also includes a feeding component 6, which is located on the side opposite to the feeding component 5 of the first flattening member 21 or the second flattening member 22, and is used to feed the first flattening member 21 and the second flattening member 22.

[0141] Specifically, see Figure 6A Both the first conveyor belt 211 and the second conveyor belt 221 have output ends 220 along the second direction, and the unloading assembly 6 is along the second direction ( Figure 6A (in the X-axis direction) located on the side where the output end 220 of the first conveyor belt 211 is located ( Figure 6A (Right side of the first conveyor belt 211), the unloading component 6 includes a second moving component 61 and an unloading conveyor belt 62. The unloading conveyor belt 62 is disposed on the second moving component 61, and the second moving component 61 is used to drive the unloading conveyor belt 62 to move along the first direction.

[0142] Since the unloading component 6 is located on the side of the output end 220 of the first conveyor belt 211 along the second direction, and the unloading conveyor belt 62 is disposed on the second moving component 61, when the second moving component 61 drives the unloading conveyor belt 62 to move along the first direction, the unloading conveyor belt 62 can be connected to 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 unloading conveyor belt 62 is connected to the output end 220 of the first conveyor belt 211, and a battery cell D is placed on the first conveyor belt 211, the rotation of the first conveyor belt 211 can transfer the battery cell D to the unloading conveyor belt 62, thereby achieving the purpose of unloading the battery cell D on the first conveyor belt 211.

[0144] When the unloading conveyor belt 62 is connected to the output end 220 of the second conveyor belt 221, and a battery cell D is placed on the second conveyor belt 221, the rotation of the second conveyor belt 221 can transfer the battery cell D to the unloading conveyor belt 62, thereby achieving the purpose of unloading the battery cell D on the second conveyor belt 221.

[0145] As can be seen, by causing the second moving component 61 to drive the unloading conveyor belt 62 to move along the first direction, the same unloading conveyor belt 62 can automatically unload the battery cells D on the first conveyor belt 211 and the second conveyor belt 221 respectively. On the one hand, the unloading of the battery cells 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 set up separate unloading conveyor belts 62 for the first conveyor belt 211 and the second conveyor belt 221, the number of unloading conveyor belts 62 can be saved, the structure of the unloading component 6 can be simplified, and the cost of the unloading component 6 can be reduced.

[0146] The structure of the second moving component 61 may be the same as or similar to that of the first moving component 51 described above. For details, please refer to the description of the first moving component 51 in the above embodiments. This embodiment will not repeat the description here.

[0147] In some embodiments, see Figure 6B The unloading assembly 6 includes multiple unloading conveyor belts 62. The first flattening part 21 and each second flattening part 22 are respectively provided with one of the multiple unloading conveyor belts 62.

[0148] Since each of the first flattened parts 21 and each of the second flattened parts 22 is respectively provided with one of the multiple unloading conveyor belts 62, that is, each first flattened part 21 corresponds to one unloading conveyor belt 62 and each second flattened part 22 corresponds to one unloading conveyor belt 62, in this way, each first flattened part 21 and each second flattened part 22 can have its own dedicated unloading conveyor belt 62, thereby improving unloading efficiency.

[0149] In some embodiments, see Figure 4 The support frame 1 includes a guide rod 11 and a mounting component 12, wherein the guide rod 11 is along a first direction ( Figure 4 Extending along the Z-axis direction, the second flattening member 22 and the third flattening member 23 are slidably disposed on the guide rod 11 along the first direction, and the mounting member 12 is disposed on the guide rod 11 and located on the side of the third flattening member 23 opposite to the second flattening member 22. Figure 4 The first driving member 31 is disposed on the mounting member 12 (on the upper side of the third flattening member 23).

[0150] The aforementioned mounting component 12 can be a mounting plate or other possible structures, and this embodiment does not limit this.

[0151] Since the second flattening member 22 and the third flattening member 23 are slidably disposed on the guide rod 11 along the first direction, under the guiding action of the guide rod 11, the second flattening member 22 and the third flattening member 23 can slide more smoothly and steadily along the first direction.

[0152] The number of guide rods 11 can be multiple, such as two, three or four, etc. This embodiment does not limit this.

[0153] When there are multiple guide rods 11, the guide rods 11 can better guide the second flattening member 22 and the third flattening member 23, thereby making the second flattening member 22 and the third flattening member 23 slide more smoothly and steadily along the first direction.

[0154] Figure 7This is a schematic diagram of the structure of a battery cell winding device 200 provided in one embodiment of this application. See also: Figure 7 The battery cell winding equipment 200 includes a battery cell feeding and pressing device 100 for the winding equipment.

[0155] The structure of the cell feeding and pressing device 100 for the winding equipment can be the same as that of the cell feeding and pressing device 100 for the winding equipment described in any of the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the cell feeding and pressing device 100 for the winding equipment in the above embodiments. This embodiment will not repeat the description here.

[0156] In this embodiment, since the cell feeding and pressing device 100 for the winding equipment can flatten multiple cells D at once and hold multiple cells D under pressure at once, the efficiency of the cell feeding and pressing device 100 for flattening the cells D can be improved. Based on this, when the cell feeding and pressing device 100 for the winding equipment is applied to the cell winding equipment 200, the processing efficiency of the cell winding equipment 200 can be improved.

[0157] In some embodiments, the battery cell winding equipment 200 further includes a winding mechanism 201, a feeding mechanism 202, a conveying mechanism 203, and a pre-pressing mechanism 204. The winding mechanism 201 is used to wind the battery cell D, the feeding mechanism 202 is used to feed the battery cell D to the conveying mechanism 203, the pre-pressing mechanism 204 is used to pre-press the battery cell D on the conveying mechanism 203, and the conveying mechanism 203 is used to convey the pre-pressed battery cell D to the first flattening member 21 or the second flattening member 22.

[0158] In this embodiment, firstly, the winding mechanism 201 can wind up the battery cell D. Specifically, the winding mechanism 201 can include a winding needle, which can produce the battery cell D when it rotates. Next, the unloading mechanism 202 can unload the battery cell D from the winding needle onto the conveying mechanism 203. After the battery cell D is unloaded onto the conveying mechanism 203, the pre-pressing mechanism 204 can pre-press the battery cell D on the conveying mechanism 203, so that the battery cell D is initially flattened.

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

[0160] When the cell winding equipment 200 also includes a pre-pressing mechanism 204, the pre-pressing mechanism 204 can initially flatten the cell D, which prepares for subsequent secondary flattening at the first flattening part 21 or the second flattening part 22, thereby making the flattening effect of the cell D produced by the cell winding equipment 200 better.

[0161] When the battery cell winding equipment 200 also includes a feeding mechanism 202 and a conveying mechanism 203, the feeding mechanism 202 can automatically feed the battery cell D from the winding needle to the conveying mechanism 203. The conveying mechanism 203 can automatically convey the initially flattened battery cell D to the first flattening part 21 or the second flattening part 22. The whole process can be completed automatically without human intervention. Therefore, the automation level of the entire battery cell winding equipment 200 can be increased.

[0162] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
