Description
TECHNICAL FIELD
[0001] The present application relates to a folding mechanism, in particular to a continuous reciprocating folding mechanism with displacement and swing. 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. The 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 the 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 one by one. 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 as to ensure the continuous lamination process, reduce the waiting time, and improve the production efficiency.
[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.

Detailed Implementation
[0077] 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.
[0078] Example 1
[0079] like Figure 1 The diagram shown is a structural schematic of Embodiment 1 of the continuous reciprocating folding mechanism of the present invention. The continuous reciprocating folding mechanism of this embodiment includes:
[0080] Stacking table 10;

[0083] A tension stabilizing mechanism is used to maintain the tension of the strip material during reciprocating folding.
[0084] The reciprocating folding mechanism includes a folding guide mechanism and a folding drive mechanism. The folding guide mechanism includes a swing arm 11, with a moving end 111 and a swinging end 112 at its two ends. The moving end 111 of the swing arm 11 can rotate relative to a rotating shaft 12.

Specifically, the balance force applying mechanism includes a compression spring 34 for applying elastic pressure to the tension balance roller 31, or the balance force applying mechanism includes a tension spring for applying elastic tension to the tension balance roller.

[0095] The specific implementation of the continuous reciprocating folding method of the present application will be described in detail below in combination with the continuous reciprocating folding mechanism of the embodiment.
[0096] The continuous reciprocating folding method of the embodiment includes the following steps:
[0097] 1) The swing end 112 of the swing arm 11 and the first guide roller group 13 are located at the end position of the first end of the reciprocating folding of the strip material 1, and the strip material 1 at the first end is pressed and fixed by the folding positioning mechanism, as shown in Figure 6 . The angle between the swing arm 11 and the reference plane at this time reaches a positive maximum value;
[0098] 2) As shown in Figure 7 , the moving end 111 of the swing arm 11 is driven to move away from the lamination table 10 by the linear drive assembly, and the swing arm 11 is driven to rotate around the rotation shaft 12 by the swing drive assembly, so that the angle between the swing arm 11 and the reference plane is reduced. Under the combined action of the linear motion of the moving end of the swing arm and the rotation motion of the swing arm around the rotation shaft, the swing end of the swing arm moves to the second end of the reciprocating folding of the strip material relative to the lamination table;
[0099] 3) As shown in Figure 8As shown, when the angle between the swing arm and the reference plane decreases to zero, the distance between the moving end of the swing arm and the stacking table reaches its maximum value. At this time, the swing direction of the swing arm can be controlled by setting a lever or auxiliary motor. Subsequently, the linear drive assembly drives the moving end of the swing arm to move closer to the stacking table, while the swing drive assembly drives the swing arm to rotate around the axis, causing the angle between the swing arm and the reference plane to increase in the opposite direction. Under the combined action of the linear motion of the moving end of the swing arm and the rotational motion of the swing arm around the axis, the swing end of the swing arm continues to move relative to the stacking table towards the second end of the reciprocating folding process, as shown. Figure 9 As shown;
[0100] 4) When the swing end of the swing arm and the first guide roller group reach the end position of the second end of the reciprocating folding of the strip, the angle between the swing arm and the reference plane reaches its maximum value in the opposite direction. The folding positioning mechanism then presses and fixes the strip at the second end, as shown below. Figure 10-12 As shown;
[0101] 5) such as Figure 13 As shown, the linear drive assembly drives the moving end of the swing arm to move away from the stacking table, while the swing drive assembly drives the swing arm to rotate around the axis, reducing the angle between the swing arm and the reference plane. Under the combined action of the linear motion of the moving end of the swing arm and the rotational motion of the swing arm around the axis, the swing end of the swing arm moves relative to the stacking table toward the first end of the reciprocating folding of the material.
[0102] 6) For example Figure 14 As shown, when the angle between the swing arm and the reference plane decreases to zero, the distance between the moving end of the swing arm and the stacking table reaches its maximum value. At this time, the swing direction of the swing arm can be controlled by setting a lever or auxiliary motor. Subsequently, the linear drive assembly drives the moving end of the swing arm to move closer to the stacking table, while the swing drive assembly drives the swing arm to rotate around the axis, increasing the positive angle between the swing arm and the reference plane. Under the combined action of the linear motion of the moving end of the swing arm and the rotational motion of the swing arm around the axis, the swing end of the swing arm continues to move relative to the stacking table towards the first end of the reciprocating folding of the material, as shown. Figure 15 As shown;
[0103] 7) When the swing end of the swing arm and the first guide roller group reach the end position of the first end of the reciprocating folding of the strip, the angle between the swing arm and the reference plane reaches its maximum positive value. The folding positioning mechanism then presses and fixes the strip at the first end, as shown below. Figure 16-8 As shown;
[0104] 8) Repeat steps 2 to 7 until the material folding is complete.
[0105] Further, in steps 4) and 7), when the swing end 112 of the swing arm 11 and the first guide roller set 13 reach the end position of the first end or the second end of the back-and-forth folding of the strip 1, the first guide roller set 13 is driven to move towards the laminating table 10 to reduce the distance between the first guide roller set 13 and the laminating table 10, so that the strip on the first guide roller set 13 is in contact with the already folded strip located thereunder, and then the strip is pressed and fixed by the folding positioning mechanism, as shown in Figure 11 and Figure 17 When the strip is pressed and fixed by the folding positioning mechanism, the first guide roller set 13 is driven to move away from the laminating table 10 to increase the distance between the first guide roller set and the laminating table 10, so that the first guide roller set returns to the preset position, as shown in Figure 12 and 18 Specifically, the first guide roller set 13 can be driven to move towards or away from the laminating table 10 in various ways, such as driving the swing arm 11 and the first guide roller set 13 mounted on the swing arm 11 to move towards or away from the laminating table 10, or keeping the position of the moving end 111 of the swing arm 11 unchanged and controlling the swing arm 11 to rotate around the rotation shaft 12, or achieving the technical purpose of controlling the swing end 112 of the swing arm 11 to move towards or away from the laminating table 10. That is, during the driving of the first guide roller set to move towards or away from the laminating table 10, the moving end 111 of the swing arm 11 and the first guide roller set 13 can be synchronously moved, or the swing arm 11 can be rotated by a set angle relative to the rotation shaft to control the first guide roller set 13 to move towards or away from the laminating table 10.
[0106] In addition, when the swing end 112 of the swing arm is provided with a first roller frame 16, the first guide roller set 13 is mounted on the first roller frame, the first roller frame is rotationally connected with the swing arm, and a posture control motor for controlling the rotation angle of the first roller frame relative to the swing arm is mounted on the swing arm. At this time, the distance between the first guide roller set 13 and the laminating table 10 can be adjusted by controlling the first guide roller set 13. Specifically, in steps 4) and 7), when the swing end of the swing arm and the first guide roller set reach the end position of the first end or the second end of the back-and-forth folding of the strip, the first roller frame is controlled to rotate relative to the swing arm by the posture control motor to reduce the distance between the first guide roller set and the laminating table, so that the strip on the first guide roller set is in contact with the already folded strip located thereunder, and then the strip is pressed and fixed by the folding positioning mechanism; when the strip is pressed and fixed by the folding positioning mechanism, the first roller frame is controlled to rotate relative to the swing arm by the posture control motor to reset, so that the first guide roller set returns to the preset position.
[0107] Further, in the step 2), step 3), step 5) and step 6), the center of the first guide roller group 13 moves along a straight line parallel to the laminating table 10. Of course, in other embodiments, the center of the first guide roller group 13 can also move along a curved trajectory by adjusting the regularity of the movement of the moving end 111 along the preset track 14 and the regularity of the rotation of the swing arm 11 around the rotation shaft 12, which will not be repeated here.
[0108] Further, when the swing end 112 of the swing arm 11 is provided with a first roller frame, the first guide roller group is installed on the first roller frame, the first roller frame is rotationally connected with the swing arm, and the swing arm is provided with a posture control motor for controlling the rotation angle of the first roller frame relative to the swing arm, in the step 2), step 3), step 5) and step 6), the posture control motor can also be used to control the angle of the first roller frame 16 relative to the swing arm 11, so as to control the posture of the first guide roller group 13. Specifically, in the preferred embodiment, the first guide roller group includes two oppositely arranged first guide rollers, and the posture control motor is used to control the angle of the first roller frame relative to the swing arm, so that the plane in which the axes of the two first guide rollers are located remains parallel to the laminating table 10.
[0109] Further, in some embodiments, after the first roller group moves a set of n times between the first end and the second end of the back-and-forth folding of the strip, the laminating table is driven by the laminating table movement driving mechanism to move a distance s in the direction away from the first guide roller group, and s = n * h, h is the thickness of the strip, and n ≥ 1.
[0110] Specifically, when producing a battery or a capacitor, the first electrode sheet and the second electrode sheet can be alternately and complexly arranged on both sides of the diaphragm, so as to form a strip. After the strip is folded back and forth on the laminating table, there is a diaphragm 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 alternately and complexly arranged on both sides of the solid electrolyte, so as to form a strip. After the strip is folded back and forth on the laminating table, there is a 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.
[0111] The specific implementation of the continuous reciprocating laminating mechanism of the present application will be described in detail below in combination with the continuous reciprocating folding mechanism of the present embodiment.
[0112] As Figure 19As shown in the figure, it is a structural schematic diagram of the continuous reciprocating lamination mechanism of the present application. The continuous reciprocating lamination mechanism of the present embodiment comprises a continuous reciprocating folding mechanism and a sheet material lamination feeding mechanism, which is used to transport sheet material 2 in the form of a sheet and to sequentially laminate sheet material 2 on the strip material 1 after each folding of the strip material 1. Specifically, the two ends of the strip material 1 between which the strip material 1 is folded back and forth form a lamination area, and the sheet material lamination feeding mechanism comprises a sheet material feeding mechanism for transporting sheet material 2 to the lamination area and a sheet material positioning mechanism for positioning the sheet material in the set lamination area.
[0113] Further, the sheet material feeding mechanism of the present embodiment comprises:
[0114] A feeding belt 50, at least one end of the feeding belt is provided with a feeding end 51;
[0115] A feeding driving mechanism for driving the feeding end to move back and forth between its initial position and its terminal position, when both ends of the feeding belt are provided with feeding ends, the initial positions of the two feeding ends are located at the opposite ends of the lamination area respectively; and:
[0116] When the feeding end is at its initial position, the feeding end is located outside the lamination area and close to one end of the lamination area; when the feeding end is at its terminal position, the feeding end is located inside the lamination area and close to the other end of the lamination area;
[0117] A feeding control mechanism for synchronously moving the sheet material with the feeding belt during the movement of the feeding end from its initial position to its terminal position, and for allowing the sheet material to be separated from the feeding belt during the movement of the feeding end from its terminal position to its initial position.
[0118] Specifically, as Figure 19 shown, when only one end of the feeding belt 50 is provided with a feeding end 51, the opposite ends of the lamination table 10 are respectively provided with sheet material feeding mechanisms, thereby meeting the technical purpose of laminating sheet material 2 on the strip material 1 folded back and forth from the two ends of the lamination area respectively. Specifically, when the feeding end 51 is at its initial position, the feeding end 51 is located outside the lamination area and close to one end of the lamination area; when the feeding end 51 is at its terminal position, the feeding end 51 is located inside the lamination area and close to the other end of the lamination area, thereby meeting the technical purpose of feeding sheet material 2 from outside the lamination area to inside the lamination area. The feeding control mechanism of the present embodiment is used to synchronously move 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 allow 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 material positioning mechanism of the present embodiment is used to position the sheet material 2 in the set lamination area.
[0119] As Figure 22 and 23As shown, when both ends of the feeding belt 50 are provided with feeding ends 51, the starting positions of the two feeding ends 51 are respectively located at opposite ends of the lamination area, that is, the sheet material feeding mechanism at this time is only provided with one, and the technical purpose of respectively laminating sheet materials 2 on the reciprocating folded strip material 1 from both ends of the lamination area can also be met. There are two ways to set the feeding ends 51 at both ends of the lamination table 10: the first is as shown in Figure 4 As shown, there is a linkage relationship between the two feeding ends 51, that is, when one of the feeding ends 51 is located at its starting position, the other feeding end 51 is located at its end position; when one of the feeding ends 51 moves from its starting position to its end position, the other feeding end 51 moves from its end position to its starting position; when one of the feeding ends 51 moves from its end position to its starting position, the other feeding end 51 moves from its starting position to its end position. The second is as shown in Figure 5 As shown, a buffer zone is provided on the feeding belt 50, and a fixed roller 68 and a movable roller 69 are provided in the buffer zone, and the tension of the feeding belt 50 is controlled by the movable roller 69, that is, a tension mechanism 53 is formed in the buffer zone at the same time; due to the existence of the buffer zone, when the length of the feeding belt 50 in the buffer zone is long enough, the feeding ends 51 at both ends of the feeding belt 50 can be controlled respectively, that is, there is no linkage relationship between the feeding ends 51 provided at both ends of the feeding belt 50, that is, the feeding ends 51 provided at both ends of the feeding belt 50 can be controlled independently, and the control mode of each feeding end 51 is equivalent to that of Figure 1 As shown in the first embodiment, only one feeding end 51 is provided at one end of the feeding belt 50, and the details are not repeated.
[0120] Further, the feeding driving mechanism includes a driving member 52, the driving member 52 is provided one-to-one corresponding to the feeding end 51, the driving member 52 is provided below the corresponding feeding end 51, and the feeding end 51 and the corresponding driving member 52 move synchronously, and the feeding end 51 and the corresponding driving member 52 are fixedly connected in the embodiment, so that synchronous movement can be realized. Specifically, the feeding belt 50 is also provided with a tension mechanism 53, so that the feeding belt 50 can maintain sufficient tension during the movement of the feeding end 51 between its starting position and end position.
[0121] 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.
[0122] 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.
[0123] Further, in some embodiments, the feeding belt 50 is provided with rollers or balls for rolling engagement with the sheet material 2, which can reduce the friction of the sheet material 2 during disengagement from the feeding belt 50 and avoid damage to the surface of the sheet material 2.
[0124] 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 and rear ends, 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, which drives the conveying belt 58 to move and convey the sheet material 2 to the feeding end 51.
[0125] Further, the sheet material feeding mechanism of the present embodiment further comprises a sheet material slicing mechanism, which 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 sheet materials 2. Preferably, a support table 63 is provided between the cutter mechanism 61 and the rear conveying roller 57 and between the cutter mechanism 61 and the driving roller set 62, respectively, to avoid the end of the strip material 3 from tilting downward and failing 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.
[0126] 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.
[0127] 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.
[0128] 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 positioning member 67 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.
[0129] Specifically, in some embodiments, the strip 1 is a diaphragm, and the sheets 2 fed by the feeding ends 51 at both ends of the lamination table 10 are first and second electrode sheets respectively, and the first and second electrode sheets are laminated on both sides of the diaphragm respectively, so as to form a battery or capacitor structure. In other embodiments, the strip 1 includes a first electrode sheet strip, and the sheet 2 is a second electrode sheet. The first electrode sheet strip is respectively compounded with a diaphragm or a solid electrolyte layer on both sides. Alternatively, the second electrode sheet is respectively compounded with a diaphragm or a solid electrolyte layer on both sides. Alternatively, one side of the first electrode sheet strip and one side of the second electrode sheet are respectively compounded with a diaphragm or a solid electrolyte layer. In this way, after the first electrode sheet strip and the second electrode sheet are laminated, the diaphragm or the solid electrolyte layer is arranged between the adjacent first electrode sheet strip and the second electrode sheet, so as to form a battery or capacitor structure. In the embodiment, the strip 1 includes a first electrode sheet strip 4, and the first electrode sheet strip 4 is respectively compounded with a diaphragm 5 on both sides. That is, the first electrode sheet strip 4 is respectively compounded with a diaphragm 5 on both sides to form the strip 1, and the strip feeding mechanism further includes a first electrode sheet strip unwinding roller 21 for continuously unwinding the first electrode sheet strip 4 and a diaphragm compounding mechanism for respectively compounding the diaphragm 5 on both sides of the first electrode sheet strip 4. The diaphragm compounding mechanism includes a diaphragm compounding roller 22 and a diaphragm unwinding roller 23. In some embodiments, a diaphragm tension mechanism 24 is arranged between the diaphragm compounding roller 22 and the diaphragm unwinding roller 23.
[0130] Specifically, for some first electrode strip material 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 material 4 with poor folding performance, especially the product quality of the battery or capacitor after folding will affect the final forming, the first electrode strip material 4 needs to be cut into pieces first, and then the diaphragm 5 is compounded to form the strip 1. At this time, the diaphragm compounding roller 22 and the first electrode strip unwinding roller 21 are provided with an electrode cutting mechanism 25 for cutting the first electrode strip material 4. The length of the first electrode strip material cut by the electrode cutting mechanism 25 is equal to the interval between the two end positions of the back and forth folding of the strip 1. In this way, the length of the strip 1 folded back and forth is equal to the length of the first electrode strip material after the first electrode strip material 4 is cut into pieces. At this time, the position of the strip 1 folded back and forth can be controlled to be just between the two first electrode strip materials. In this way, continuous folding is realized by using flexible and foldable diaphragm 5, and the performance is not affected.
[0131] Preferably, in order to accurately control the cutting length of the first electrode strip material, an encoder 26 for measuring the cutting length of the first electrode strip material 4 is arranged between the electrode cutting mechanism 25 and the first electrode strip unwinding roller 21. In order to continuously feed the first electrode strip material 4, a feeding roller group 27 for driving the electrode feeding is arranged between the encoder 26 and the electrode cutting mechanism 25. In order to enable the first electrode strip unwinding roller 21 to continuously unwind the first electrode strip material 4 at a set speed, a first electrode strip buffer area 28 is arranged between the encoder 26 and the first electrode strip unwinding roller 21. The first electrode strip buffer area 28 includes fixed rollers and movable rollers, and will not be described again.
[0132] Further, a hot pressing compounding mechanism is arranged between the diaphragm compounding roller 22 and the strip 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 embodiment includes a heating box 29 for heating the strip 1 and a hot roller pressing compounding roller group 30 for hot roller pressing the strip 1.
[0133] The specific implementation of the continuous reciprocating lamination method of the present application will be described in detail below in combination with the continuous reciprocating lamination mechanism of the embodiment.
[0134] The continuous reciprocating lamination method of the embodiment includes the following steps:
[0135] 1) The swinging end of the swing arm and the first guide roller group are located at the end position of the first end of the strip folded back and forth, and the strip at the first end is pressed and fixed by the folding positioning mechanism, as shown in 24; with the plane perpendicular to the lamination table and passing through the axis of the rotating shaft as the reference plane, the included angle between the swing arm and the reference plane reaches the maximum positive value at this time;
[0136] 2) as shown in Figure 25As shown, the linear drive assembly drives the moving end of the swing arm to move away from the stacking table, while the swing drive assembly drives the swing arm to rotate around the axis, reducing the angle between the swing arm and the reference plane. Under the combined action of the linear motion of the moving end of the swing arm and the rotational motion of the swing arm around the axis, the swing end of the swing arm moves relative to the stacking table toward the second end of the reciprocating folding of the material.
[0137] 3) such as Figure 26 As shown, when the angle between the swing arm and the reference plane decreases to zero, the distance between the moving end of the swing arm and the stacking table reaches its maximum value. Subsequently, the linear drive assembly drives the moving end of the swing arm to move closer to the stacking table, while the oscillating drive assembly drives the swing arm to rotate around its axis, causing the angle between the swing arm and the reference plane to increase in the opposite direction. Under the combined action of the linear motion of the swing arm's moving end and the rotational motion of the swing arm around its axis, the oscillating end of the swing arm continues to move relative to the stacking table towards the second end of the reciprocating folding process, as shown... Figure 27 As shown;
[0138] 4) When the swing end of the swing arm and the first guide roller group reach the end position of the second end of the reciprocating folding of the strip, the angle between the swing arm and the reference plane reaches its maximum value in the opposite direction. The folding positioning mechanism then presses and fixes the strip at the second end, as shown below. Figure 28-30 As shown;
[0139] 5) The sheet-like materials are stacked onto the strip using a sheet-stacking feeding mechanism, such as... Figure 29-30 As shown;
[0140] 6) For example Figure 31 As shown, the linear drive assembly drives the moving end of the swing arm to move away from the stacking table, while the swing drive assembly drives the swing arm to rotate around the axis, reducing the angle between the swing arm and the reference plane. Under the combined action of the linear motion of the moving end of the swing arm and the rotational motion of the swing arm around the axis, the swing end of the swing arm moves relative to the stacking table toward the first end of the reciprocating folding of the material.
[0141] 7) For example Figure 32 As shown, when the angle between the swing arm and the reference plane decreases to zero, the distance between the moving end of the swing arm and the stacking table reaches its maximum value. Subsequently, the linear drive assembly drives the moving end of the swing arm to move closer to the stacking table, while the oscillating drive assembly drives the swing arm to rotate around its axis, increasing the positive angle between the swing arm and the reference plane. Under the combined action of the linear motion of the swing arm's moving end and the rotational motion of the swing arm around its axis, the oscillating end of the swing arm continues to move relative to the stacking table towards the first end of the reciprocating folding of the material, as shown... Figure 33 As shown;
[0142] 8) When the swing end of the swing arm and the first guide roller group reach the end position of the first end of the strip material to be folded back and forth, the included angle between the swing arm and the reference plane reaches a positive maximum value, and the first end of the strip material is pressed and fixed by the folding positioning mechanism, as shown in Figure 34-36
[0143] 9) The sheet material stack in sheet shape is placed on the strip material by the sheet material stack feeding mechanism, as shown in Figure 35-36
[0144] 10) Steps 2 to 9 are cycled until the strip material folding is completed.
[0145] Further, in steps 4) and 8), when the swing end of the swing arm and the first guide roller group reach the end position of the first end or the second end of the strip material to be folded back and forth, the first guide roller group is driven to move towards the stack table to reduce the distance between the first guide roller group and the stack table, so that the strip material on the first guide roller group is in contact with the already folded strip material below, and then the folding positioning mechanism is used to press and fix the strip material; after the strip material is pressed and fixed by the folding positioning mechanism, the first guide roller group is driven to move away from the stack table to increase the distance between the first guide roller group and the stack table, so that the first guide roller group returns to the preset position. Specifically, the first guide roller group 13 can be driven to move towards or away from the stack table 10 in various ways, such as driving the swing arm 11 and the first guide roller group 13 mounted on the swing arm 11 to move towards or away from the stack table 10, or keeping the position of the moving end 11 of the swing arm unchanged and controlling the swing arm 11 to rotate around the rotation shaft 12, or achieving the technical purpose of controlling the swing end 112 of the swing arm 11 to move towards or away from the stack table 10. That is, during the driving of the first guide roller group to move towards or away from the stack table 10, the moving end 111 of the swing arm and the first guide roller group 13 can be moved synchronously; or the swing arm 11 can be rotated by a set angle relative to the rotation shaft to control the first guide roller group 13 to move towards or away from the stack table 10.
[0146] In addition, when the swing end 112 of the swing arm is provided with the first roller frame 16, the first guide roller set 13 is installed on the first roller frame; the first roller frame is rotationally connected with the swing arm, and the swing arm is provided with a posture control motor for controlling the rotation angle of the first roller frame relative to the swing arm. At this time, the distance between the first guide roller set 13 and the laminated sheet table 10 can be adjusted by controlling the first guide roller set 13. Specifically, in steps 4) and 8), when the swing end of the swing arm and the first guide roller set reach the end position of the first end or the second end of the strip material back and forth folding, the posture control motor is used to control the rotation of the first roller frame relative to the swing arm, so as to reduce the distance between the first guide roller set and the laminated sheet table, so that the strip material on the first guide roller set is in close contact with the strip material below which has been folded, and then the strip material is fixed by the folding positioning mechanism; after the strip material is fixed by the folding positioning mechanism, the posture control motor is used to control the rotation of the first roller frame relative to the swing arm to reset, so that the first guide roller set returns to the preset position.
[0147] Further, in steps 2), 3), 6) and 7), the center of the first guide roller set moves along a straight line parallel to the laminated sheet table. Of course, in other embodiments, by adjusting the movement of the moving end 111 along the preset track 14 and the rotation of the swing arm 11 around the rotation shaft 12, the center of the first guide roller set 13 can also move along a curved trajectory, which will not be repeated here.
[0148] Further, when the swing end 112 of the swing arm 11 is provided with the first roller frame, the first guide roller set is installed on the first roller frame; the first roller frame is rotationally connected with the swing arm, and the swing arm is provided with a posture control motor for controlling the rotation angle of the first roller frame relative to the swing arm. In steps 2), 3), 6) and 7), the posture control motor can also be used to control the angle of the first roller frame relative to the swing arm to control the posture of the first guide roller set. Specifically, in the preferred embodiment, the first guide roller set includes two oppositely arranged first guide rollers, and the posture control motor is used to control the angle of the first roller frame relative to the swing arm, so that the plane in which the axes of the two first guide rollers are located remains parallel to the laminated sheet table 10.
[0149] Further, in some embodiments, after the first roller set moves between the first end and the second end of the strip material back and forth folding for a set of N times, the laminated sheet table is driven by the laminated sheet table moving drive mechanism to move a distance S in the direction away from the first guide roller set, and S=N*H, H is the sum of the thickness of one layer of strip material and one layer of sheet material, and N≥1.
[0150] Specifically, the method for stacking the sheet material in the form of a sheet on the strip material by using the sheet material conveying mechanism includes the following steps:
[0151] (1) Move the feeding end 51 to its initial position; at this time, the lamination feeding mechanism is arranged at both ends of the lamination table 10, and the lamination feeding mechanism at the left is the first lamination feeding mechanism, and the lamination feeding mechanism at the right is the second lamination feeding mechanism; the action process of the first lamination feeding mechanism will be described below. Specifically, as shown in Figure 24 , the feeding end 51 of the first lamination feeding mechanism is at its initial position.
[0152] (2) After the sheet 2 is fed to the feeding end, the feeding end 51 is driven by the feeding driving mechanism to move towards its terminal position, and the sheet 2 is driven to move synchronously with the feeding belt 50 under the action of the feeding control mechanism. As shown in Figure 25-29 , the feeding end 51 of the first lamination feeding mechanism moves from its initial position towards its terminal position.
[0153] (3) After the feeding end 51 reaches its terminal position, the end of the sheet 2 is positioned in the lamination area by the sheet positioning mechanism. As shown in Figure 30 , the feeding end 51 of the first lamination feeding mechanism reaches its terminal position, and the end of the sheet 2 is positioned and pressed in the lamination area by the sheet positioning member 67.
[0154] (4) Drive the feeding end 51 to move towards its initial position, and make the sheet 2 gradually separate from the feeding belt 50 under the action of the feeding mechanism until it completely falls into the lamination area. As shown in Figure 30-35 , the feeding end 51 of the first lamination feeding mechanism moves from its terminal position towards its initial position, and the sheet 2 gradually separates from the feeding belt 50 in this process.
[0155] (5) Continue to drive the feeding end 51 to move towards its initial position until the feeding end 51 returns to its initial position. As shown in Figure 36 , the feeding end 51 of the first lamination feeding mechanism reaches its initial position.
[0156] Further, in order to enable the sheet positioning mechanism to position the end of the sheet 2 in the lamination area, the following two methods can be used:
[0157] The first method: in step (2), when the sheet 2 is fed to the feeding end 51, the end of the sheet 2 is exposed outside the feeding end 51; in step 3), the end of the sheet exposed outside the feeding end is positioned in the lamination area by the sheet positioning mechanism.
[0158] The second method: in step (3), when the feeding end 51 reaches its terminal position, the sheet 2 is driven to move by the feeding control mechanism, so that the end of the sheet is exposed outside the feeding end, and then the end of the sheet exposed outside the feeding end is positioned in the lamination area by the sheet positioning mechanism.
[0159] Both methods allow the end of the sheet 2 to protrude beyond the feeding end 51, thereby enabling the sheet positioning mechanism to position the protruding end of the sheet in the stacking area, or the sheet positioning member 37 to press and position the protruding end of the sheet in the stacking area.
[0160] Example 2
[0161] like Figure 37 The diagram shown is a structural schematic of Embodiment 2 of the continuous reciprocating folding mechanism of the present invention. The continuous reciprocating folding mechanism of this embodiment includes:
[0162] Stacking table 10;
[0163] A reciprocating folding mechanism is used to reciprocate folding the strip material 1 into a strip shape on the stacking table 10;
[0164] The folding positioning mechanism is used to control the positions of both ends of the tape 1 during reciprocating folding.
[0165] The reciprocating folding mechanism includes a folding guide mechanism and a folding drive mechanism. The folding guide mechanism includes a swing arm 11, with a moving end 111 and a swinging end 112 at its two ends. The moving end 111 of the swing arm 11 can rotate relative to a rotating shaft 12. The swinging end 112 is provided with a first guide roller group 13 for guiding the strip material 1. The folding drive mechanism includes a drive component for driving the moving end 111 of the swing arm 11 to move along a preset track 14 and a swing component for driving or guiding the swing arm 11 to rotate around the rotating shaft 12. The preset track 14 includes at least one vertical track perpendicular to the stacking table 10. The first guide roller group 13 reciprocates relative to the stacking table 10 under the combined motion of the moving end 111 of the swing arm moving along a direction perpendicular to the stacking table 10 and the rotational motion of the swing arm 11 around the rotating shaft 12, so as to fold the strip material 1 back and forth on the stacking table 10.
[0166] The preset track in this embodiment includes two vertical tracks perpendicular to the stacking table 10. The ends of the two vertical tracks furthest from the stacking table are connected by an arc track, such as... Figure 37 As shown; or two vertical tracks are connected at both ends by circular arc tracks, such as... Figure 38 As shown. In this embodiment, the two vertical tracks are connected by an arc track at the ends away from the stacking table. During the folding process, the moving end 111 of the swing arm 11 moves along the preset track. Since the two vertical tracks are parallel to each other, when the swing arm 11 is perpendicular to the stacking table 10, the linear velocity of the moving end 111 of the swing arm 11 is parallel to that of the stacking table 10, thereby avoiding the swing arm 11 from having a swing dead angle.
