Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of battery or capacitor manufacturing, and particularly relates to a continuous reciprocating swing folding mechanism, a folding method, a laminating mechanism and a laminating method. BACKGROUND

[0002] Chinese patent application with publication number CN113555595A discloses a hot composite lamination equipment and a hot composite lamination method, and specifically, a lamination mechanism is described in the specification. Specifically, the lamination mechanism includes a material box and a blowing assembly. The upper end of the material box is provided with an opening. A main conveying mechanism drives the material belt to enter the material box from the opening of the material box in the vertical direction. The blowing assembly is arranged on one side of the material box. When the end of the material belt enters the upper end of the material box, the blowing assembly blows air to the other side of the material box, so that the end of the material belt is blown to abut against the other side of the material box. Then, the material belt abuts against the material box and continues to move downward, realizing positioning of the first unit piece. Then, the blowing assembly stops blowing air, and the material belt freely falls and is folded in a Z shape, so that the unit pieces are stacked in the material box in sequence. When the unit pieces are stacked to a preset number, the material belt is cut, at this time, the material box filled with unit pieces is away from the lower side of the material belt, and the empty material box is moved to the lower side of the material belt, so that the lamination process is continuously carried out, the waiting time is reduced, and the production efficiency is improved.

[0003] Although the lamination mechanism can theoretically meet the lamination requirements of the material belt, the lamination accuracy cannot be guaranteed. During lamination, only the blowing assembly is used to blow the material belt for lamination, and the falling position and folding position of the material belt cannot be accurately controlled. The position accuracy of lamination is required to be high during battery manufacturing. If the lamination error is large, the battery products produced will be scrapped. If other auxiliary means are used after lamination to improve the lamination accuracy, relative movement will occur between the materials after lamination, which will affect the surface performance of the materials after lamination, and will also lead to the decline of the quality of the battery products produced.

[0037] Further, the sheet material pressing mechanism includes sheet material pressing rods, sheet material pressing pins or sheet material pressing blocks respectively located at the two ends of the sheet material.

[0038] The application also provides a continuous reciprocating swing laminating method, comprising the following steps:

[0039] 1) The folding roller group is located at the end position of the first end of the strip material, and the strip material on the first end is fixed and pressed by the folding positioning mechanism;

[0045] Further, in the step 1), after the strip material of the first end is pressed and fixed by the folding positioning mechanism, the swing shaft is driven to move to increase the distance between the folding roller set and the surface of the sheet material stacking table.

[0046] Further, in the steps 2) and 4), after the sheet material is stacked on the strip material, the sheet material is pressed and fixed.

[0048] Further, after the folding roller set moves to the end position of the second end of the strip material to be folded back and forth relative to the sheet material stacking table, the swing shaft is continuously driven to move towards the sheet material stacking table by a set distance to reduce the distance between the folding roller set and the surface of the sheet material stacking table, so that the strip material on the uppermost layer is attached to the strip material below, and then the strip material of the second end is pressed and fixed by the folding positioning mechanism.

[0051] Further, after the folding roller group moves to the end position of the first end of the back-and-forth folding of the strip, the driving swing shaft continues to move towards the laminating table by a set distance, reduces the distance between the folding roller group and the table surface of the laminating table, and makes the uppermost strip adhere to the strip below, and then the strip at the second end is fixed by the folding positioning mechanism.

[0052] Further, after the strip at the first end is fixed by the folding positioning mechanism, the driving swing shaft moves away from the laminating table by a set distance, and increases the distance between the folding roller group and the table surface of the laminating table.

Detailed Implementation

[0088] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0089] Example 1

[0090] like Figure 1 The diagram shown is a structural schematic of Embodiment 1 of the continuous reciprocating swing folding mechanism of the present invention. The continuous reciprocating swing folding mechanism of this embodiment includes:

[0091] Stacking table 10;

[0092] The conveyor belt mechanism is used to continuously convey the conveyor belt 1 and fold the conveyor belt 1 back and forth on the stacking table 10.

[0093] A sheet material conveying mechanism is used to convey sheet material 2 in sheet form and to stack sheet material 2 on the belt material 1 in sequence after each folding of the belt material 1;

[0094] The folding positioning mechanism is used to control the positions of both ends of the tape 1 during reciprocating folding.

[0095] Specifically, the conveyor belt mechanism includes a swing shaft 30, a swing arm 31 that swings synchronously with the swing shaft 30, and a folding drive mechanism for driving the swing shaft 30. The swing arm 31 is equipped with a folding roller assembly, which includes two folding rollers 11 for guiding the conveyor belt 1. The folding drive mechanism drives the swing shaft 30 to reciprocate within a set angle range, causing the folding roller assembly to reciprocate relative to the stacking table 10 to fold the conveyor belt 1 back and forth on the stacking table 10. While the swing arm swings, the folding drive mechanism drives the swing shaft 30 to move, adjusting the distance between the folding roller assembly and the stacking table 10, as well as between the stacked electrodes, to prevent interference between the folding roller assembly and the stacking table 10, and between the stacked electrodes.

[0096] Further, the folding positioning mechanism comprises positioning rods, positioning press pins or positioning blocks respectively located at the two end positions of the strip 1. The folding positioning mechanism of the embodiment comprises positioning blocks 12 respectively located at the two end positions of the strip 1. The positioning blocks 12 are arranged to press the end positions of the folded strip 1, so that the strip 1 can be positioned and folded. Specifically, the positioning blocks 12 press the uppermost layer of the strip 1. Of course, the same technical purpose can also be achieved by using positioning rods and positioning press pins, which will not be repeated.

[0097] Further, the swing shaft 30 is further provided with a secondary swing arm 32 that swings synchronously with the swing shaft 30. The secondary swing arm 32 is provided with two secondary guide rollers 33 for guiding the strip 1. The secondary guide rollers 33 can better guide the strip 1. Specifically, the included angle between the swing arm 31 and the secondary swing arm 32 is 180°. The swing shaft 30 is provided with a middle guide roller 34 that rotates with the swing shaft 30 and is used to guide the strip 1. Of course, in some embodiments, the included angle between the swing arm 31 and the secondary swing arm 32 can be less than 180°, and the same technical purpose of guiding the strip 1 by the guide roller 17 can also be achieved.

[0098] Further, the continuous reciprocating swing folding mechanism of the embodiment further comprises a strip buffer mechanism. The strip buffer mechanism comprises fixed rollers located on both sides. The two fixed rollers are provided with a movable roller 16 and a tension mechanism for driving the movable roller 16 to move to control the tension of the strip 1. Specifically, the two fixed rollers are a first fixed guide roller 27 and a second fixed guide roller 14. The first fixed guide roller 27 and the second fixed guide roller 14 are provided with a movable roller 16 and a tension mechanism for driving the movable roller 16 to move to control the tension of the strip 1. The tension mechanism drives the movable roller 16 to move, so that the tension of the strip 1 can be kept stable. A certain length of the strip 1 can also be stored between the first fixed guide roller 27, the movable roller 16 and the second fixed guide roller 14 to meet the requirements of the strip 1 and also serve as a buffer. Specifically, the tension mechanism can be realized by using various existing tension stabilizing mechanisms, which will not be repeated. Further, the strip 1 passes through the first fixed guide roller 27, the movable roller 16 and the second fixed guide roller 14 in sequence and then enters the strip conveying mechanism. The second fixed guide roller 14 is provided with two oppositely arranged fixed guide rollers. In this way, the strip 1 can be guided during the reciprocating swing of the folding roller group.

[0099] Further, the continuous reciprocating swing folding mechanism of the embodiment further comprises a stack table moving drive mechanism for driving the stack table 10 to move in a direction perpendicular to the table surface of the stack table 10, so as to adjust the height of the uppermost layer of the strip 1. Specifically, the stack table moving drive mechanism can be realized by using various existing linear drive mechanisms, such as ball screw mechanisms and gear and rack mechanisms.

[0100] The folding driving mechanism of the embodiment comprises a swing driving mechanism for driving the swing shaft 30 to rotate within a set angle range and a moving driving mechanism for driving the swing shaft to move. The swing driving mechanism is used to drive the swing arm 31 to swing back and forth, thereby driving the folding roller set to move back and forth between the first end and the second end of the strip material 1 to realize the back and forth folding of the strip material 1. The moving driving mechanism is used to drive the swing arm 31 to move along a direction perpendicular to the table surface of the laminating table 10, thereby adjusting the distance between the swing shaft 30 and the table surface of the laminating table 10, i.e. adjusting the distance between the folding roller set and the strip material 1 located at the uppermost layer, so as to avoid the interference between the folding roller set and the laminating table 10 and the strip material 1 located at the uppermost layer. Specifically, the swing driving mechanism can be realized in various ways, such as a servo motor or a linkage mechanism driven by a motor, which will not be repeated. Similarly, the moving driving mechanism can also be realized in various ways, such as a ball screw mechanism and a gear and rack mechanism, which will not be repeated.

[0101] The continuous back and forth swing folding mechanism of the embodiment can continuously convey the strip material by setting the strip material conveying mechanism, drive the swing shaft to move by the folding driving mechanism, drive the swing arm to rotate around the swing shaft within a set angle range, and adjust the distance between the folding roller set and the laminating table at the same time. In this way, the folding roller set can move back and forth relative to the laminating table. When the folding roller set moves to the first end of the folding relative to the laminating table, the strip material located at the end of the first end of the back and forth folding is pressed and fixed by the folding positioning mechanism, and then the folding roller set moves to the second end of the folding relative to the laminating table, and the strip material located at the end of the second end of the back and forth folding is pressed and fixed by the folding positioning mechanism again. In this way, the strip material can be positioned and folded on the laminating table, and the positions of the two ends of the folding are precisely positioned and controlled by the folding positioning mechanism, so that not only the continuous folding can be realized, but also the folding precision can be improved. In addition, by controlling the distance between the folding roller set and the laminating table, the length between the first end and the second end of the back and forth folding of the strip material can be controlled, so that the folding requirements of different sizes can be met, especially for the folding requirements of larger length sizes, and the versatility is better.

[0102] Specifically, when producing a battery or a capacitor, the first electrode sheet and the second electrode sheet can be interlaced and compounded on both sides of the separator respectively, so as to form a strip material. After the strip material is folded back and forth on the laminating table, there is a layer of separator between the adjacent first electrode sheet and the second electrode sheet, so as to form a battery or a capacitor structure, which can meet the production of the battery or the capacitor. Of course, the first electrode sheet and the second electrode sheet can also be interlaced and compounded on both sides of the solid electrolyte respectively, so as to form a strip material. After the strip material is folded back and forth on the laminating table, there is a layer of solid electrolyte between the adjacent first electrode sheet and the second electrode sheet, so as to form a solid battery or a solid capacitor structure, which can meet the production of the solid battery or the solid capacitor.

[0103] The continuous reciprocating swing folding method of the present application will be described in detail below in combination with the above continuous reciprocating swing folding mechanism.

[0104] The continuous reciprocating swing folding method of the present embodiment comprises the following steps:

[0105] 1) The folding roller set is positioned at the end position of the first end of the strip material reciprocating folding, and the strip material at the first end is tightly fixed by the folding positioning mechanism, as shown in Fig. 1. Figure 3 Specifically, after the strip material at the first end is tightly fixed by the folding positioning mechanism, the swing shaft is driven to move to increase the distance between the folding roller set and the table surface of the lamination table, as shown in Fig. 2. Figure 4

[0106] 2) The swing shaft is swung and moved by the folding driving mechanism, so that the folding roller set moves to the end position of the second end of the strip material reciprocating folding relative to the lamination table, and the strip material at the second end is tightly fixed by the folding positioning mechanism, as shown in Fig. 3. Figures 5-7 During the swinging of the folding roller set towards the second end of the strip material reciprocating folding, the swing shaft is first driven to move away from the lamination table to increase the distance between the swing shaft and the lamination table, and when the swing arm is perpendicular to the table surface of the lamination table, the distance between the swing shaft and the lamination table reaches the maximum, as shown in Fig. 4. Figure 5 Then the swing shaft is driven to move towards the lamination table to reduce the distance between the swing shaft and the lamination table. When the folding roller set moves to the end position of the second end of the strip material reciprocating folding relative to the lamination table, the swing shaft is continuously driven to move towards the lamination table by a set distance to reduce the distance between the folding roller set and the table surface of the lamination table, so that the strip material on the uppermost layer is attached to the strip material below, and then the strip material at the second end is tightly fixed by the folding positioning mechanism, as shown in Fig. 5. Figure 7 When the strip material at the second end is tightly fixed by the folding positioning mechanism, the swing shaft is driven to move away from the lamination table by a set distance to increase the distance between the folding roller set and the table surface of the lamination table, as shown in Fig. 6. Figure 8

[0107] 3) The swing shaft is swung and moved by the folding driving mechanism, so that the folding roller set moves to the end position of the first end of the strip material reciprocating folding relative to the lamination table, and the strip material at the first end is tightly fixed by the folding positioning mechanism, as shown in Fig. 7. Figures 9-11 During the swinging of the folding roller set towards the first end of the strip material reciprocating folding, the swing shaft is first driven to move away from the lamination table to increase the distance between the swing shaft and the lamination table, and when the swing arm is perpendicular to the table surface of the lamination table, the distance between the swing shaft and the lamination table reaches the maximum, as shown in Fig. 8. Figure 9 ​​As shown in the figure; then the driving swing shaft moves towards the laminating table to reduce the distance between the swing shaft and the laminating table. When the folding roller group moves to the end position of the first end of the strip material to be folded back and forth, the driving swing shaft continues to move towards the laminating table by a certain distance, reducing the distance between the folding roller group and the laminating table surface, so that the strip material on the uppermost layer is in contact with the strip material below, and then the folding positioning mechanism is used to press and fix the strip material at the second end, as shown in the figure. Figure 11 When the strip material at the first end is pressed and fixed by the folding positioning mechanism, the driving swing shaft moves away from the laminating table by a certain distance, increasing the distance between the folding roller group and the laminating table surface, as shown in the figure. Figure 4

[0108] 4) Repeat steps 2) to 3) until the folding is completed.

[0109] Further, in step 2) and / or step 3), when the folding roller group moves between the first end and the second end of the strip material to be folded back and forth for a certain n times, the driving laminating table moves a distance s in the second direction away from the side where the folding roller group is located, and s = n*h, h is the thickness of the strip material, n≥1.

[0110] Example 2

[0111] As shown in the figure, it is a structural schematic diagram of the continuous reciprocating swing laminating mechanism of the present application, which is example 2. The continuous reciprocating swing laminating mechanism of this embodiment includes a continuous reciprocating swing folding mechanism and a sheet material conveying mechanism, which is used to convey sheet-shaped sheet materials 2 and make the sheet materials 2 be stacked on the strip material 1 in turn after each folding of the strip material 1. Figure 12 Further, the sheet material conveying mechanism is provided with two and is located at the two ends perpendicular to the axis of the swing shaft 30 or at the two sides parallel to the axis of the swing shaft 30; or the sheet material conveying mechanism is provided with one and is located at one side parallel to the axis of the swing shaft 30. Specifically, if the sheet materials are two kinds, such as the first pole piece and the second pole piece, the sheet material conveying mechanism needs to be provided with two; if the sheet materials are only one kind, such as the first pole piece or the second pole piece, the sheet material conveying mechanism can be provided with only one; of course, if the sheet materials are only one kind, such as the first pole piece or the second pole piece, the sheet material conveying mechanism can also be provided with two. The sheet material conveying mechanism of this embodiment is provided with two and is located at the two ends perpendicular to the axis of the swing shaft 30, and the two sheet material conveying mechanisms stack the sheet-shaped sheet materials 2 on the uppermost strip material 1 in turn. Specifically, the sheet material conveying mechanism 17 can be realized by using various existing sheet material conveying mechanisms 17, such as conveying belt mechanism, conveying roller mechanism and mechanical hand device, etc., which will not be repeated here.

[0112]

[0113] ​​Further, the continuous reciprocating folding mechanism of the embodiment further comprises a sheet material alignment driving mechanism for driving the sheet material conveying mechanism to move along a direction perpendicular to the folding table top. That is, the spacing between the sheet material conveying mechanism 17 and the folding table 10 can be adjusted by driving the sheet material conveying mechanism 17 to move relative to the folding table 10 to meet the sheet material 2 folding requirements.

[0114] Further, the continuous reciprocating folding mechanism of the embodiment further comprises a sheet material pressing mechanism, specifically, the sheet material pressing mechanism is used to press and fix the uppermost sheet material 2 on the corresponding strip material 1 to prevent the sheet material 2 from being displaced or misaligned during the reciprocating folding of the strip material 1. The sheet material pressing mechanism comprises sheet material pressing rods, sheet material pressing pins or sheet material pressing blocks respectively located at both ends of the sheet material 2. The sheet material pressing mechanism of the embodiment comprises sheet material pressing blocks 15 respectively located at both ends of the sheet material 2.

[0115] Specifically, in some embodiments, the strip material 1 is a separator or a solid electrolyte, and the sheet material 2 conveyed by the feeding end 51 located at both ends of the folding table 10 is a first electrode sheet and a second electrode sheet respectively, and the first electrode sheet and the second electrode sheet are respectively folded on both sides of the separator or the solid electrolyte, thereby forming a battery or capacitor structure. In some other embodiments, the strip material 1 comprises a first electrode sheet strip, and the sheet material 2 is a second electrode sheet; the first electrode sheet strip is respectively compounded with a separator or a solid electrolyte layer on both sides; or, the second electrode sheet is respectively compounded with a separator or a solid electrolyte layer on both sides; or, one side of the first electrode sheet strip and one side of the second electrode sheet are respectively compounded with a separator or a solid electrolyte layer. In this way, after the first electrode sheet strip and the second electrode sheet are folded, the adjacent first electrode sheet strip and the second electrode sheet have a separator or a solid electrolyte layer therebetween, and a battery or capacitor structure can also be formed. The strip material 1 of the embodiment comprises a first electrode sheet strip 4, and the first electrode sheet strip 4 is respectively compounded with a separator 5 on both sides. That is, the first electrode sheet strip 4 is respectively compounded with a separator 5 on both sides to form a strip material 1, and the strip material feeding mechanism further comprises a first electrode sheet strip unwinding roller 17 for continuously unwinding the first electrode sheet strip 4 and a separator compounding mechanism for respectively compounding the separator 5 on both sides of the first electrode sheet strip 4, the separator compounding mechanism comprises a separator compounding roller 18 and a separator unwinding roller 19, and in some embodiments, a separator tensioning mechanism 20 is arranged between the separator compounding roller 18 and the separator unwinding roller 19.

[0116] Specifically, for some first electrode strip materials with excellent folding performance, the first electrode strip material 4 can be directly folded back and forth on the lamination table 10 after the diaphragm 5 is compounded on both sides of the first electrode strip material 4. For some first electrode strip materials 4 with poor folding performance, especially those that will affect the quality of the final shaped battery or capacitor after folding, the first electrode strip material 4 needs to be cut into pieces first, and then the diaphragm 5 is compounded to form the strip material 1. At this time, the diaphragm compounding roller 18 and the first electrode strip material unwinding roller 17 are provided with an electrode cutting mechanism 21 for cutting the first electrode strip material 4. The length of the first electrode strip material cut by the electrode cutting mechanism 21 is equal to the distance between the two end positions of the back-and-forth folding of the strip material 1. In this way, after the first electrode strip material 4 is cut into pieces, the length of the strip material 1 folded back and forth is equal to the length of the first electrode strip material. At this time, the position of the strip material 1 folded back and forth can be controlled to be just between the two first electrode strip materials. In this way, continuous folding is achieved by using flexible and foldable diaphragm 5, and the performance is not affected.

[0117] Preferably, in order to accurately control the cutting length of the first electrode strip material, an encoder 22 for measuring the cutting length of the first electrode strip material 4 is arranged between the electrode cutting mechanism 21 and the first electrode strip material unwinding roller 17. In order to continuously feed the first electrode strip material 4, a feeding roller group 23 for driving the electrode feeding is arranged between the encoder 22 and the electrode cutting mechanism 21. In order to enable the first electrode strip material unwinding roller 17 to continuously unwind the first electrode strip material 4 at a set speed, a first electrode strip material buffer area 24 is arranged between the encoder 22 and the first electrode strip material unwinding roller 17. The first electrode strip material buffer area 18 includes fixed rollers and movable rollers, and will not be repeated here.

[0118] Further, a hot pressing compounding mechanism is arranged between the diaphragm compounding roller 18 and the strip material folding mechanism to improve the compounding performance between the diaphragm 5 and the first electrode strip material 4. The hot pressing compounding mechanism of the present embodiment includes a heating box 25 for heating the strip material 1 and a hot roller pressing compounding roller group 26 for hot roller pressing the strip material 1.

[0119] The sheet material feeding mechanism of the present embodiment includes a feeding belt 50, a feeding drive mechanism, a feeding control mechanism, and a sheet material positioning mechanism. At least one end of the feeding belt 50 of the present embodiment is provided as a feeding end 51. The feeding drive mechanism of the present embodiment is used to drive the feeding end 51 to move back and forth between its starting position and end position.

[0120] Specifically, as shown in FIG. 6, the feeding drive mechanism of the present embodiment includes a feeding drive motor 52, a feeding drive belt 53, and a feeding drive belt pulley 54. The feeding drive motor 52 is arranged on the feeding end 51 of the feeding belt 50. The feeding drive belt 53 is arranged on the feeding end 51 of the feeding belt 50. The feeding drive belt pulley 54 is arranged on the feeding end 51 of the feeding belt 50. Figure 12As shown in FIG. 1, when only one feeding end 51 is provided at one end of the feeding belt 50, the sheet feeding mechanism is provided at the opposite ends of the sheet stacking table 10, so as to meet the technical purpose of respectively stacking the sheet material 2 on the to-and-fro folded strip material 1 from the two ends of the sheet stacking area. Specifically, when the feeding end 51 is at its initial position, the feeding end 51 is located outside the sheet stacking area and close to one end of the sheet stacking area; when the feeding end 51 is at its terminal position, the feeding end 51 is located inside the sheet stacking area and close to the other end of the sheet stacking area, so as to meet the technical purpose of feeding the sheet material 2 from outside the sheet stacking area to inside the sheet stacking area. The feeding control mechanism of the present embodiment is used to synchronize the movement of the sheet material 2 with the feeding belt 50 during the movement of the feeding end 51 from its initial position to its terminal position, and to enable the sheet material 2 to be separated from the feeding belt 50 during the movement of the feeding end 51 from its terminal position to its initial position. The sheet positioning mechanism of the present embodiment is used to position the sheet material 2 in the set sheet stacking area.

[0121] As shown in FIG. 2, when both ends of the feeding belt 50 are provided with feeding ends 51, the initial positions of the two feeding ends 51 are located at the opposite ends of the sheet stacking area, i.e., the sheet feeding mechanism is provided with only one feeding end 51 at this time, and the technical purpose of respectively stacking the sheet material 2 on the to-and-fro folded strip material 1 from the two ends of the sheet stacking area can also be met. Figure 13 and 14 As shown in FIG. 2, when both ends of the feeding belt 50 are provided with feeding ends 51, the initial positions of the two feeding ends 51 are located at the opposite ends of the sheet stacking area, i.e., the sheet feeding mechanism is provided with only one feeding end 51 at this time, and the technical purpose of respectively stacking the sheet material 2 on the to-and-fro folded strip material 1 from the two ends of the sheet stacking area can also be met. Figure 13 As shown in FIG. 3, the two feeding ends 51 have a linkage relationship, i.e., when one of the feeding ends 51 is at its initial position, the other feeding end 51 is at its terminal position; when one of the feeding ends 51 moves from its initial position to its terminal position, the other feeding end 51 moves from its terminal position to its initial position; and when one of the feeding ends 51 moves from its terminal position to its initial position, the other feeding end 51 moves from its initial position to its terminal position. Figure 14 As shown in FIG. 4, a buffer area is provided on the feeding belt 50, and a fixed roller 68 and a movable roller 69 are provided in the buffer area, and the movable roller 69 is used to control the tension of the feeding belt 50, i.e., a tension mechanism 53 is formed in the buffer area at the same time; due to the existence of the buffer area, when the length of the feeding belt 50 in the buffer area is long enough, the feeding ends 51 at the two ends of the feeding belt 50 can be controlled respectively, i.e., there is no linkage relationship between the feeding ends 51 provided at the two ends of the feeding belt 50 at this time, i.e., the feeding ends 51 provided at the two ends of the feeding belt 50 can be controlled independently, and the control mode of each feeding end 51 is equivalent to that shown in FIG. 1, and thus repeated description is omitted. Figure 1

[0122] ​Further, the feeding driving mechanism comprises driving members 52, which are arranged one-to-one with the feeding ends 51. The driving members 52 are arranged below the corresponding feeding ends 51, and the feeding ends 51 move synchronously with the corresponding driving members 52. In this embodiment, the feeding ends 51 are fixedly connected with the corresponding driving members 52, so that synchronous movement can be achieved. Specifically, the feeding belt 50 is also provided with a tensioning mechanism 53, so that the feeding belt 50 can maintain sufficient tension during the movement of the feeding ends 51 between the initial position and the terminal position.

[0123] Further, the feeding control mechanism comprises a control member 54, which is arranged corresponding to the driving member 52 and moves synchronously with the driving member 52, and is arranged above the corresponding feeding end 51. The control member 54 is used to make the sheet material 2 move synchronously with the feeding belt 50 during the movement of the feeding end 51 from the starting position to the end position, and can be separated from the feeding belt 50 during the movement of the feeding end 51 from the end position to the starting position. To achieve the technical purpose, the control member 54 can be implemented in various ways. The first way is that the control member 54 is provided with a gap control mechanism, which is used to adjust the gap between the control member 54 and the driving member 52. By adjusting the gap between the control member 54 and the driving member 52, when the feeding end 51 moves from the starting position to the end position, the gap between the control member 54 and the driving member 52 can be reduced, so that the sheet material 2 is subjected to appropriate pressure and moves synchronously with the feeding belt 50; when the feeding end 51 moves from the end position to the starting position, the gap between the control member 54 and the driving member 52 can be increased, i.e. the sheet material 2 is not subjected to pressure, so that the sheet material 2 can be separated from the feeding belt 50. The second way is that the control member 54 is a control roller, which can only rotate in one direction and the tangential velocity of the point closest to the feeding belt 50 during the rotation of the control roller points to the end position of the corresponding feeding end 51; in this way, when the feeding end 51 moves from the starting position to the end position, the control roller is subjected to the friction force exerted by the sheet material 2 towards the side where the starting position of the corresponding feeding end 51 is located, the torque exerted on the control roller by the friction force is opposite to the direction in which the control roller can rotate, so that the control roller does not rotate under the action of the friction force, i.e. the sheet material 2 does not slide on the feeding belt 50, so that the sheet material 2 moves synchronously with the feeding belt 50; when the feeding end 51 moves from the end position to the starting position, the sheet material 2 is separated from the feeding belt 50, so that the control roller is subjected to the friction force exerted towards the side where the end position of the corresponding feeding end 51 is located, at this time, the torque exerted on the control roller by the friction force is the same as the direction in which the control roller can rotate, so that the control roller rotates under the action of the friction force, so that the sheet material 2 can be separated from the feeding belt 50. Of course, there are various ways to realize that the control roller can only rotate in one direction, such as using a motor to control the rotation direction of the control roller, or setting a ratchet on the rotating shaft of the control roller, and the like, which will not be repeated. In some embodiments, when the control member 54 is a control roller, a gap control mechanism can also be arranged on the control member 54. Of course, the gap control mechanism can be implemented in various ways, such as an electric cylinder, a threaded screw mechanism, and the like, which will not be repeated.

[0124] Further, in some embodiments, a guide piece 55 for guiding the sheet material 2 when it is separated from the feeding belt 50 is arranged below the feeding end 51, and the guide piece 55 moves synchronously with the driving member 52. By arranging the guide piece 55, the sheet material 2 can be prevented from being damaged by excessive bending during the separation from the feeding belt 50.

[0125] Further, in some embodiments, the feeding belt 50 is provided with rollers or balls for rolling cooperation with the sheet material 2, so as to reduce the friction of the sheet material 2 during the process of separating from the feeding belt 50, and avoid damage to the surface of the sheet material 2.

[0126] Further, the sheet material feeding mechanism of the present embodiment further comprises a sheet material conveying mechanism for conveying the sheet material 2 to the feeding end 51, and the sheet material conveying mechanism is provided in one-to-one correspondence with the feeding end 51. Specifically, the sheet material conveying mechanism of the present embodiment comprises a front conveying roller 56 and a rear conveying roller 57 respectively located at the front end and the rear end, and a conveying belt 58 is provided between the front conveying roller 56 and the rear conveying roller 57; the feeding belt 21 is provided with a receiving roller 59, and the receiving roller 59 is arranged close to the front conveying roller 56. Of course, the sheet material conveying mechanism further comprises a sheet material conveying motor (not shown in the figure) for driving the front conveying roller 56 or the rear conveying roller 57 to rotate, so as to drive the conveying belt 58 to move and convey the sheet material 2 to the feeding end 51.

[0127] Further, the sheet material feeding mechanism of the present embodiment further comprises a sheet material slicing mechanism, and the sheet material slicing mechanism comprises a unwinding roller 60 for continuously unwinding the strip material, a cutter mechanism 61 for cutting the strip material to form the sheet material, and a driving roller set 62 for driving the strip material 3 to the cutter mechanism 61, and the cutter mechanism 61 is located between the rear conveying roller 57 and the driving roller set 62. By providing the sheet material slicing mechanism, the continuous strip material 3 can be cut into the sheet material 2. Preferably, a support table 63 is respectively provided between the cutter mechanism 61 and the rear conveying roller 57 and between the cutter mechanism 61 and the driving roller set 62, so as to avoid the end of the strip material 3 from being inclined downward and unable to smoothly enter the cutter mechanism 61 and the rear conveying roller 57. Specifically, the strip material 3 of the present embodiment is a second pole piece.

[0128] Preferably, in some embodiments, an encoder 64 for length measurement is provided between the driving roller set 62 and the unwinding roller 60, so as to ensure the dimensional accuracy of each sheet material 2.

[0129] Preferably, in some embodiments, a strip material buffer zone is provided between the encoder 64 and the unwinding roller 60 for buffering the strip material 3. The strip material buffer zone of the present embodiment comprises a fixed roller 65 and a tension movable roller 66, so that the unwinding roller 60 can continuously unwind at a set speed and will not be affected by the interval feeding of the sheet material 2.

[0130] Further, the sheet positioning mechanism of the embodiment includes a sheet positioning member 67 arranged at the end position close to the corresponding feeding end 51. The sheet positioning member 67 can be a sheet pressing rod, a sheet pressing pin, a sheet pressing block, etc. In the embodiment, the sheet positioning member 67 is a sheet pressing block. When the feeding end 51 moves to the end position, the sheet pressing block is used to press and fix the end of the sheet 2 on the strip 1 which has been folded in the lamination area, so as to realize the lamination positioning of the sheet 2. During the movement of the feeding end 51 to the starting position, the sheet 2 is separated from the feeding strip 50.

[0131] The specific implementation of the continuous reciprocating folding mechanism of the embodiment is the same as that of the embodiment 1, and will not be described again.

[0132] The specific implementation of the continuous reciprocating folding method of the embodiment will be described in detail in combination with the continuous reciprocating folding mechanism.

[0133] The continuous reciprocating folding method of the embodiment includes the following steps:

[0134] 1) The folding roller group is arranged at the end position of the first end of the reciprocating folding of the strip 1, and the strip at the first end is pressed and fixed by the folding positioning mechanism, as shown in FIG. 4. Figure 15 After the strip at the first end is pressed and fixed by the folding positioning mechanism, the swing shaft 30 is driven to move to increase the distance between the folding roller group and the table surface of the lamination table 10, as shown in FIG. 5. Figure 16

[0135] 2) The sheet-shaped sheet 2 is laminated on the strip 1 by the sheet conveying mechanism, as shown in FIG. 6. Figure 16 After the sheet 2 is laminated on the strip 1, the sheet 2 is pressed and fixed.

[0136] When the strip 1 is a diaphragm, the sheet-shaped first pole sheet or second pole sheet is laminated on the strip 1 at this time;

[0137] When the strip 1 is a first pole sheet, the sheet-shaped second pole sheet is laminated on the first pole sheet at this time;

[0138] When the strip 1 is a second pole sheet, the sheet-shaped first pole sheet is laminated on the first pole sheet at this time.

[0139] 3) The swing shaft 30 is driven to swing and move by the folding driving mechanism, so that the folding roller group moves to the end position of the second end of the reciprocating folding of the strip 1, and the strip 1 at the second end is pressed and fixed by the folding positioning mechanism, as shown in FIG. 7. Figures 17-20 ​As shown in Fig. 6, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. As shown in Fig. 7, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. Figure 17 As shown in Fig. 6, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. As shown in Fig. 7, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. Figure 19 As shown in Fig. 6, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. As shown in Fig. 7, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. Figure 20 As shown in Fig. 6, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. As shown in Fig. 7, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding.

[0140] 4) The sheet material 2 in the form of a sheet is stacked on the strip material 1 by using the sheet material conveying mechanism, as shown in Fig. 8. Figure 20 When the sheet material 2 is stacked on the strip material 1, the sheet material 2 is pressed and fixed.

[0141] When the strip material 1 is a diaphragm, if the first pole piece is stacked on the diaphragm in step 2), then the second pole piece is stacked on the diaphragm in step 4); if the second pole piece is stacked on the diaphragm in step 2), then the first pole piece is stacked on the diaphragm in step 4).

[0142] When the strip material 1 is a first pole piece, then the second pole piece in the form of a sheet is stacked on the first pole piece at this time.

[0143] When the strip material 1 is a second pole piece, then the first pole piece in the form of a sheet is stacked on the first pole piece at this time.

[0144] 5) The folding roller set is moved to the end position of the first end of the strip material 1 for folding by driving the swing shaft 30 to swing and move by using the folding driving mechanism, and the strip material 1 at the first end is pressed and fixed by using the folding positioning mechanism, as shown in Fig. 5. Figures 21-23 As shown in Fig. 6, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. As shown in Fig. 7, the folding roller set is first moved to the end position of the second end of the strip material 1 for folding, and then the folding roller set is moved to the end position of the first end of the strip material 1 for folding. Figure 21As shown; and then the driving swing shaft 30 moves towards the laminating table 10 to reduce the distance between the swing shaft 30 and the laminating table 10, so as to control the distance between the folding roller group and the laminating table 10 and the laminating sheet on the uppermost layer, to avoid interference and prevent the distance from being too large. When the folding roller group moves to the end position of the first end of the strip 1 for back-and-forth folding relative to the laminating table 10, the driving swing shaft 30 continues to move towards the laminating table 10 by a set distance, reducing the distance between the folding roller group and the laminating table 10, so that the strip 1 on the uppermost layer is in contact with the sheet 2 below, and then the folding positioning mechanism is used to press and fix the strip 1 at the second end, as shown. Figure 23 When the strip 1 at the first end is pressed and fixed by the folding positioning mechanism, the driving swing shaft 30 moves away from the laminating table 10 by a set distance, increasing the distance between the folding roller group and the laminating table 10, as shown. Figure 16

[0145] 6) Repeat steps 2) to 5) until the laminating is completed.

[0146] In step 3) and / or step 5), when the folding roller group moves between the first end and the second end of the strip for back-and-forth folding by a set number N times, the laminating table is driven to move in the second direction towards the side away from the folding roller group by a distance S, and S=N*H, H is the sum of the thickness of one layer of strip and one layer of sheet, and N≥1.

[0147] Specifically, the method for stacking the sheet-shaped sheet on the strip by using the sheet conveying mechanism includes the following steps:

[0148] (1) Move the feeding end 51 to its starting position; at this time, the sheet stacking feeding mechanism is arranged at both ends of the laminating table 10, and the sheet stacking feeding mechanism on the left is the first sheet stacking feeding mechanism, and the sheet stacking feeding mechanism on the right is the second sheet stacking feeding mechanism; the action process of the first sheet stacking feeding mechanism will be described in detail below. Specifically, as shown in the state, Figure 15 the feeding end 51 of the first sheet stacking feeding mechanism is located at its starting position.

[0149] (2) After the sheet 2 is sent to the feeding end, the feeding end 51 is driven by the feeding driving mechanism to move towards its end position, and the sheet 2 moves synchronously with the feeding belt 50 under the action of the feeding control mechanism. As shown, Figures 16-18 the feeding end 51 of the first sheet stacking feeding mechanism moves from its starting position towards its end position.

[0150] (3) After the feeding end 51 reaches its end position, the end of the sheet 2 is positioned in the laminating area by using the sheet positioning mechanism. As shown, Figure 19 ​As shown, the feeding end 51 of the first sheet stacking feeding mechanism reaches its end position, and the end of the sheet 2 is positioned and pressed against the stacking area by the sheet positioning member 67.

[0151] (4) The feeding end 51 is driven to move towards its starting position, and the sheet 2 is gradually separated from the feeding belt 50 under the action of the feeding mechanism until it completely falls into the stacking area. As shown, Figures 20-22 As shown, the feeding end 51 of the first sheet stacking feeding mechanism moves from its end position towards its starting position, and the sheet 2 is gradually separated from the feeding belt 50 during the process.

[0152] (5) Continue to drive the feeding end 51 to move towards its starting position until the feeding end 51 returns to its starting position. As shown, Figure 23 As shown, the feeding end 51 of the first sheet stacking feeding mechanism reaches its starting position.

[0153] Further, in order to enable the sheet positioning mechanism to position the end of the sheet 2 in the stacking area, the following two methods can be used:

[0154] The first method: in step (2), when the sheet 2 is sent to the feeding end 51, the end of the sheet 2 is exposed outside the feeding end 51; in step (3), the sheet positioning mechanism is used to position the end of the sheet exposed outside the feeding end in the stacking area.
