Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of production of laminations of batteries or capacitors, and in particular to a sheet material lamination mechanism, a sheet material-belt material collaborative lamination mechanism and a collaborative lamination method. BACKGROUND

[0002] Chinese patent application CN113555595A discloses a hot composite lamination equipment and a hot composite lamination method, and in particular, 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 belt material 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 belt material 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 belt material is blown to abut against the other side of the material box. Then, the belt material abuts against the material box and continues to move downward, realizing positioning of the first sheet unit. Then, the blowing assembly stops blowing air, and the belt material freely falls and is folded in a Z shape, so that the sheet units are stacked in the material box one by one. When the sheet units are stacked to a preset number, the belt material is cut, at which time the material box filled with sheet units is away from the lower side of the belt material, and the empty material box is moved to the lower side of the belt material, so as to ensure continuous lamination process, reduce waiting time and improve production efficiency.

[0003] Although the lamination mechanism can theoretically meet the lamination requirements of the belt material, the lamination accuracy cannot be guaranteed. During lamination, only the blowing assembly is used to blow the belt material for lamination, and the falling position and folding position of the belt material 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 properties of the materials after lamination, and will also lead to a decrease in the quality of the battery products produced.

[0048] The present application also provides a sheet material-strip material cooperative lamination method, wherein a reciprocating folding mechanism drives the strip material to fold back and forth on a lamination table, in the process that the reciprocating folding mechanism drives the strip material to move from one end to the other end of the back-and-forth folding, a sheet material conveying mechanism conveys the sheet material to a position close to the lamination table; the reciprocating folding mechanism drives the strip material to reach the other end from one end of the back-and-forth folding, and a folding positioning mechanism is used for positioning to complete one folding of the strip material, and then a sheet material transferring mechanism is used for stacking the sheet material beside the lamination table on the strip material which has been folded on the lamination table; after the sheet material stacking is completed, the reciprocating folding mechanism is used for driving the strip material to move towards the other end of the back-and-forth folding, and the process is repeated until the lamination is completed.

[0049] Further, the reciprocating folding mechanism comprises a folding guide mechanism and a folding driving mechanism; the folding guide mechanism comprises a swing arm, two ends of the swing arm are respectively a moving end and a swing end, the moving end of the swing arm can rotate relative to a rotating shaft, and the swing end is provided with a first guide roller group for guiding the strip material, the folding driving mechanism comprises a driving assembly for driving the moving end of the swing arm to move along a preset track and a swing assembly for driving or guiding the swing arm to rotate around the rotating shaft, and the preset track comprises at least one vertical track perpendicular to the lamination table; under the combined action of the linear motion of the first guide roller group along the direction perpendicular to the lamination table and the rotary motion of the swing arm around the rotating shaft, the first guide roller group moves back and forth relative to the lamination table to fold the strip material back and forth on the lamination table.

[0050] The method comprises the following steps:

[0051] 1) Position the swing end of the swing arm and the first guide roller at the end of the first end of the reciprocating folding of the strip. Use the folding positioning mechanism to press and fix the strip at the first end. Use the linear drive assembly to control the moving end of the swing arm to move away from the stacking table, so that the distance between the first guide roller group and the stacking table increases to the set value.

[0052] Sheets are stacked on a stacking table using a sheet stacking mechanism;

[0053] 2) 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, so that the angle between the swing arm and the reference plane is reduced. 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.

[0054] 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. Then, 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, so that the angle between the swing arm and the reference plane increases 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 towards the second end of the reciprocating folding of the material relative to the stacking table.

[0055] During this process, the sheet material is transported to the position near the stacking table using a sheet material conveying mechanism;

[0056] 3) 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 included angle between the swing arm and the reference plane reaches the maximum value in the opposite direction. The folding positioning mechanism is used to press and fix the strip at the second end. Then, the linear drive assembly is used to drive the moving end of the swing arm to move away from the stacking table, so that the distance between the first guide roller group and the stacking table increases to the set value.

[0057] Sheets are stacked on a stacking table using a sheet stacking mechanism;

[0058] 4) The swing arm is driven to rotate around the axis by the swing drive assembly, which reduces 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. When the angle between the swing arm and the reference plane is reduced to zero, the distance between the moving end of the swing arm and the stacking table reaches its maximum value. After that, the moving end of the swing arm is driven to move toward the stacking table by the linear drive assembly, while the swing drive assembly is driven to rotate around the axis, which increases 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 toward the first end of the reciprocating folding of the material.

[0059] During this process, the sheet material is transported to the position near the stacking table using a sheet material conveying mechanism;

[0060] 5) 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 included angle between the swing arm and the reference plane reaches the maximum positive value. The folding positioning mechanism is used to press and fix the strip at the first end. Then, the linear drive assembly is used to drive the moving end of the swing arm to move away from the stacking table, so that the distance between the first guide roller group and the stacking table increases to the set value.

[0061] 6) Repeat steps 2 to 5 until the stacking is complete.

[0062] Furthermore, the sheet material transfer mechanism includes a fixed base located above the sheet material conveying mechanism and a movable base located between the fixed base and the sheet material conveying mechanism. The fixed base is provided with a first drive mechanism for driving the movable base to move vertically. The movable base is provided with a horizontal slide rail, and a sliding seat that slides with the horizontal slide rail is provided with the slide rail. A suction cup is arrayed on the bottom surface of the sliding seat. The movable base is provided with a second drive mechanism for driving the sliding seat to reciprocate between the stacking table and the sheet material conveying mechanism along the horizontal slide rail.

[0063] In steps 1) and 3), the sliding seat is driven to move above the stacking table, and the moving seat is driven to move downward using the first driving mechanism to stack the sheet material on the top layer of the already folded strip material. Then, the moving seat is driven to move upward to the set position, and the sliding seat is driven to move above the sheet material conveying mechanism.

[0064] In steps 2) and 4), the sheet material is conveyed to a position near the stacking table and corresponds to the position of the suction cup using the sheet material conveying mechanism; then the moving seat is driven to move downward, and after the suction cup picks up the sheet material, the moving seat is driven to reset upward.

[0065] The beneficial effects of this invention are as follows:

[0066] The sheet stacking mechanism of the present invention conveys the sheet material to a position near the stacking table through a sheet material conveying mechanism, and then transfers the sheet material to the stacking table through a sheet material transfer mechanism, thereby achieving the technical objective of stacking the sheet material on the stacking table.

[0067] The sheet-strip collaborative stacking mechanism of the present invention uses a reciprocating folding mechanism to fold the strip material back and forth on the stacking table. After the reciprocating folding mechanism drives the strip material to complete one fold and is positioned by the folding positioning mechanism, the sheet material stacking mechanism stacks the sheet material on the topmost strip material that has already been folded, thereby achieving the technical objective of collaborative stacking of sheet and strip materials. This can effectively improve stacking efficiency, especially for larger sheet materials. Simply using the sheet material transfer mechanism to drive the sheet material stacking is less efficient. In this case, by coordinating with the reciprocating folding method of the strip material, the efficiency of large-size stacking can be greatly improved. Attached Figure Description

However, the embodiments described are not intended to limit the present invention.

[0095] Example 1

[0096] like Figure 1 The diagram shown is a structural schematic of Embodiment 1 of the sheet-strip collaborative stacking mechanism of the present invention.

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 linear motion of the moving end 111 of the swing arm 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.

[0103] Furthermore, such as Figure 7 As shown, the preset track 14 in this embodiment includes a vertical track perpendicular to the stacking table 10. A sliding block 15 is provided within the vertical track and slidably engages with it. The moving end 111 of the swing arm 11 and the sliding block 15 are rotatably engaged via a rotating shaft 12. In some other embodiments, the preset track may also be configured to include two vertical tracks perpendicular to the stacking table 10, with the ends of the two vertical tracks furthest from the stacking table connected by an arc track, such as... Figure 13 As shown; or two vertical tracks are connected at both ends by circular arc tracks, such as... Figure 14As shown, 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.

[0104] Furthermore, during the reciprocating movement of the moving end 111 of the swing arm 11 along the preset track 14, there are two main ways to control the rotation of the swing arm 11 around the pivot 12: one is a non-powered mode, in which the swing component includes a swing track (not shown in the figure), and a slider is provided on the swing arm 11. The slider slides with the swing track and can rotate relative to the swing track. Specifically, take any point on the swing arm 11 and install the slider at that point. The path of this point during the reciprocating movement of the moving end 11 of the swing arm along the preset track 14 and the reciprocating movement of the swing end 112 of the swing arm along the preset track is the swing track. The slider slides with the swing track and rotates with the swing arm 11. Since the center line of the swing track is a curve, the slider adjusts its posture by rotating around the swing arm 11 during the movement along the swing track to prevent the slider from getting stuck in the swing track. Another method is a powered approach. In this case, the swing assembly includes a swing control motor for controlling the swing arm to rotate around the axis. The swing control motor controls the swing arm 11 to rotate around the axis 12 according to a set pattern, which can also achieve the technical purpose of driving the swing end 112 of the swing arm 11 to reciprocate relative to the stacking table 10 along a set trajectory line 141. Specifically, in this embodiment, the trajectory line 141 of the reciprocating movement of the swing end 112 relative to the stacking table 10 is a straight line parallel to the stacking table 10, that is, the trajectory of the center of the first guide roller group 13 relative to the stacking table 10 is a straight line parallel to the stacking table 10. Of course, in some other embodiments, the trajectory line 141 of the reciprocating movement of the swing end 112 relative to the stacking table 10 can also be a curve or other shapes, which will not be described further.

[0105] Furthermore, the swing end of the swing arm 11 is provided with a first roller frame 16, and the first guide roller group 13 is mounted on the first roller frame 16; the first roller frame 16 is fixedly mounted on the swing arm 11, such as... Figure 9 As shown; or a rotational engagement between the first roller frame 16 and the swing arm 11, such as Figure 8As shown. The first guide roller group 13 includes two opposing first guide rollers, with a first symmetry plane parallel to their axes between the two first guide rollers; when the first roller frame 16 is fixedly mounted on the swing arm 11, the axis of the rotating shaft 12 falls on the first symmetry plane; when the first roller frame 16 and the swing arm 11 are rotatably engaged, the axis of the first rotating shaft 161 of the first roller frame 16 relative to the swing arm 11 falls on the first symmetry plane. Specifically, in some embodiments, when the first roller frame 16 and the swing arm 11 are rotatably engaged, an attitude control motor is mounted on the swing arm 11 to control the rotation angle of the first roller frame 16 relative to the swing arm 11, so as to control the attitude of the first roller frame 16 in real time, so as to facilitate the guidance of the strip 1 during the stacking process.

[0106] Furthermore, the sheet-strip collaborative stacking mechanism of this embodiment also includes a second guide roller group 17 for guiding the strip 1 to the first guide roller group 13; the second guide roller group 17 of this embodiment is fixedly disposed relative to the preset track 14. Of course, in some other embodiments, a second roller frame 171 can also be provided at the moving end of the swing arm 11, and the second guide roller group 17 is mounted on the second roller frame, such as... Figure 4 As shown, the second guide roller group 17 at this time includes two second guide rollers arranged opposite each other, and there is a second symmetry plane between the two second guide rollers that is parallel to their axis. The axis of the rotating shaft 12 falls on the second symmetry plane.

[0107] Furthermore, the tension stabilizing mechanism includes a tension balancing roller 31 disposed on the feed side of the second guide roller group 17 and a balancing force applying mechanism for applying pressure from the tension balancing roller 31 to the strip 1. Specifically, as shown in FIG6, in this embodiment, two tension balancing rollers 31 are provided and located on both sides of the second strip 1, respectively, with the two tension balancing rollers 31 staggered. Of course, in some other embodiments, the tension balancing roller 31 can also be a single roller (e.g., Figure 12 (As shown), or set to three or more roots, which will not be elaborated further. For example... Figure 10 As shown, in a preferred embodiment, the tension stabilizing mechanism includes a balance roller frame 32 with a central rotating shaft 33 at its center. The balance roller frame 32 can rotate around the central rotating shaft 33. Two tension balancing rollers 31 are respectively installed at both ends of the balance roller frame 32, thus enabling linkage between the two tension balancing rollers 31. Under the action of the balancing force application mechanism of each tension balancing roller, the balance roller frame 32 is subjected to a torque. This torque is balanced by the reaction force of the tension of the strip 1 on the tension balancing roller, thereby allowing real-time adjustment of the tension of the strip 1 and maintaining its stability. Specifically, the balancing force application mechanism includes a compression spring 34 for applying elastic pressure to the tension balancing roller 31, or the balancing force application mechanism includes a tension spring for applying elastic tension to the tension balancing roller. In this embodiment, the balancing force application mechanism includes a compression spring 34 for applying elastic pressure to the tension balancing roller 31, which will not be described further.

[0108] Furthermore, the folding positioning mechanism includes positioning rods, positioning pins, or positioning blocks 18 located at both ends of the reciprocating folding of the strip 1. In this embodiment, the folding positioning mechanism includes positioning blocks 18 located at both ends of the reciprocating folding of the strip 1. By setting the positioning blocks 18 to press on the folded ends of the strip 1, the strip 1 can be positioned and folded. Specifically, the positioning blocks 18 press on the topmost strip 1. Of course, the same technical purpose can also be achieved by using positioning rods and positioning pins in the folding positioning mechanism, which will not be elaborated further.

[0109] Furthermore, the sheet-strip collaborative stacking mechanism of this embodiment also includes a strip buffer mechanism. The strip buffer mechanism includes fixed rollers 19 located on both sides, a movable roller 20 and a tension mechanism for driving the movable roller 20 to move to control the tension of the strip 1 are provided between the fixed rollers 19 on both sides, and the strip 1 enters the reciprocating folding mechanism after passing through the buffer mechanism.

[0110] Furthermore, the sheet-strip collaborative stacking mechanism of this embodiment also includes a stacking table moving drive mechanism for driving the stacking table 10 to move in a direction perpendicular to its table surface. The stacking table moving drive mechanism can be implemented by means of a screw mechanism or a gear and rack mechanism, etc., which will not be described in detail here. By setting the stacking table moving drive mechanism to drive the stacking table 10 to move in a direction perpendicular to its table surface, when the thickness of the folded strip 1 is relatively thick, the stacking table 10 can be driven to move to make way.

[0111] In some embodiments, the strip 1 is a separator, requiring two sheet conveying mechanisms 40. The sheets 2 conveyed by the two sheet conveying mechanisms are respectively the first electrode and the second electrode. The first electrode and the second electrode are stacked on both sides of the separator, thereby forming a battery or capacitor structure. In other embodiments, the strip 1 includes a first electrode strip, and the sheet 2 is the second electrode; a separator or solid electrolyte layer is laminated on both sides of the first electrode strip; or, a separator or solid electrolyte layer is laminated on both sides of the second electrode; or, a separator or solid electrolyte layer is laminated on one side of the first electrode strip and the second electrode. Thus, after the first electrode strip and the second electrode are stacked, a separator or solid electrolyte layer is formed between adjacent first electrode strips and second electrodes, which can also form a battery or capacitor structure. In this embodiment, the strip 1 includes a first electrode strip 4, and a separator 5 is laminated on both sides of the first electrode strip 4. That is, diaphragms 5 are respectively laminated on both sides of the first electrode strip 4 to form a strip 1. The strip feeding mechanism also includes a first electrode strip unwinding roller 21 for continuously unwinding the first electrode strip 4 and a diaphragm laminating mechanism for laminating diaphragms 5 on both sides of the first electrode strip 4. The diaphragm laminating mechanism includes a diaphragm laminating roller 22 and a diaphragm unwinding roller 23. In some embodiments, a diaphragm tension mechanism 24 is provided between the diaphragm laminating roller 22 and the diaphragm unwinding roller 23.

[0112] Specifically, for some first electrode strips with excellent folding performance, separators 5 can be laminated to both sides of the first electrode strip 4 and then directly folded back and forth on the stacking table 10. For some first electrode strips 4 with poor folding performance, especially those whose folding will affect the quality of the final battery or capacitor product, the first electrode strip 4 needs to be sliced ​​first, and then laminated with separators 5 to form strip 1. At this time, an electrode cutting mechanism 25 for cutting the first electrode strip 4 is provided between the separator laminating roller 22 and the first electrode strip unwinding roller 21. The length of the first electrode sheet cut by the electrode cutting mechanism 25 is equal to the distance between the two ends of the strip 1 during back and forth folding. In this way, after the first electrode strip 4 is sliced, the length of the strip 1 during back and forth folding is equal to the length of the first electrode sheet. At this time, the position of the strip 1 during back and forth folding can be controlled to be exactly between the two first electrode sheets. Thus, continuous folding is achieved by utilizing the flexible and foldable separator 5 without affecting the performance. In this embodiment, the strip 1 includes a first strip 4 in the shape of a strip and sheet 5 laminated on the first strip 4, with a gap 3 between adjacent sheets 5. The sheet-strip co-lamination mechanism of this embodiment also includes a hot-pressing lamination device for thermally laminating the strip, such as... Figure 15 As shown.

[0113] Preferably, to precisely control the slicing length of the first electrode sheet, an encoder 26 for measuring the cutting length of the first electrode sheet 4 is provided between the electrode cutting mechanism 25 and the first electrode strip unwinding roller 21. To drive the continuous feeding of the first electrode sheet 4, a feeding roller group 27 for driving the electrode feeding is provided between the encoder 26 and the electrode cutting mechanism 25. To enable the first electrode sheet unwinding roller 21 to continuously prevent the first electrode sheet 4 from winding at a set speed, a first electrode sheet buffer area 28 is provided between the encoder 26 and the first electrode sheet unwinding roller 21. The first electrode sheet buffer area 28 includes a fixed roller and a moving roller, etc., which will not be described further.

[0114] Furthermore, in this embodiment, the strip 1 includes a second strip in the shape of a strip and a sheet in the shape of a sheet laminated on the second strip, with a gap between adjacent sheets; that is, the second strip is the diaphragm 5 or a solid electrolyte, and the sheet 4a is obtained by slicing the first electrode strip 4 by the electrode cutting mechanism 25, that is, the sheet 4a includes a current collector and an active material layer coated on the current collector. The sheet-strip co-stacking mechanism in this embodiment also includes a hot-pressing composite device for thermally composited strips. Specifically, the hot-pressing composite device is disposed between the diaphragm composite roller 22 and the strip folding mechanism to improve the composite performance between the diaphragm 5 and the first electrode strip 4.

[0115] like Figure 16As shown, the hot pressing composite device of this embodiment includes a heating device 29 for heating the strip material and a hot rolling composite device for hot rolling the heated strip material. The hot rolling composite device includes a hot pressing roller group 30, and tension roller groups 35 for balancing tension are respectively provided on both sides of the hot pressing roller group 30. The hot pressing roller group 30 includes two hot pressing rollers arranged opposite each other. At least one of the two hot pressing rollers can move in a direction perpendicular to its axis and parallel to the axes of the two hot pressing rollers. By controlling the movement of the hot pressing rollers, the pressure applied by the hot pressing roller group 30 to the strip material 1 can be adjusted. In this embodiment, only one of the two hot pressing rollers can move in a direction perpendicular to its axis and parallel to the axes of the two hot pressing rollers. Of course, in some other embodiments, both hot pressing rollers can be configured to move in a direction perpendicular to their axes and parallel to the axes of the two hot pressing rollers, which will not be elaborated further. The tension roller group 35 includes two tension rollers arranged opposite each other; at least one of the two tension rollers can move in a direction perpendicular to its axis and parallel to the axes of the two tension rollers. By controlling the movement of the tension rollers, the pressure applied by the tension roller group 35 to the strip 1 can be adjusted. In this embodiment, only one of the two hot pressing rollers can move in a direction perpendicular to its axis and parallel to the axes of the two tension rollers. Of course, in some other embodiments, both tension rollers can be configured to move in a direction perpendicular to their axes and parallel to the axes of the two tension rollers, which will not be elaborated further. Specifically, in this embodiment, the distance between the plane passing through the axes of the two tension rollers belonging to the same tension roller group 35 and the plane passing through the axes of the two hot pressing rollers is greater than or equal to the distance between two adjacent sheets 4a. Further, the hot pressing composite device in this embodiment also includes a tension mechanism 36 for maintaining a set tension in the composite strip within the heating device 29; the tension mechanism 36 is located on the rear side of the heating device, and the hot pressing composite device is located on the front side of the heating device.

[0116] Specifically, when the rear end of a sheet 4a is located behind the hot press roller group 30, and the distance between the rear end of the sheet 4a and the hot press roller group 30 is less than or equal to a set threshold, the hot press rollers are driven to move, increasing the distance between the two hot press rollers and reducing the pressure applied by the hot press rollers to the strip 1. At the same time, the tension rollers of the two tension roller groups 35 are driven to move, decreasing the distance between the two tension rollers belonging to the same tension roller group 35 and increasing the pressure applied by the tension rollers to the composite strip, thereby reducing or even eliminating the pressure applied by the hot press roller group to the composite strip due to the decrease in pressure. The resulting tension fluctuations; when the front end of the next sheet 4a passes the hot press roller group 30 and is located in front of the hot press roller group 30, and the distance between the front end of the sheet 4a and the hot press roller group 30 is greater than or equal to a set threshold, the hot press roller is driven to move, so that the distance between the two hot press rollers is reduced, and the pressure applied by the hot press roller to the composite strip is increased; at the same time, the tension rollers of the two tension roller groups 35 are driven to move, so that the distance between the two tension rollers belonging to the same tension roller group 35 is increased, and the pressure applied by the tension roller to the strip 1 is reduced, so as to achieve hot roller pressing of the strip 1.

[0117] This embodiment also proposes a sheet-strip collaborative stacking method. A reciprocating folding mechanism drives the strip to fold back and forth on the stacking table 10. During the process of the reciprocating folding mechanism driving the strip to move from one end of the reciprocating folding to the other, the sheet conveying mechanism 40 conveys the sheet 2 to a position adjacent to the stacking table 10. The reciprocating folding mechanism drives the strip from one end of the reciprocating folding to the other, and the folding positioning mechanism positions it, completing one fold of the strip. Then, the sheet transfer mechanism stacks the sheet 2 located next to the stacking table on top of the strip 1 already folded on the stacking table. After the sheet 2 is stacked, the reciprocating folding mechanism drives the strip 1 to move towards the other end of the reciprocating folding, and this cycle repeats until the stacking is complete. Figures 17 to 21 As shown, the specific process is as follows:

[0118] 1) Position the swing end 112 of the swing arm 11 and the first guide roller group 13 at the end position of the first end of the reciprocating folding of the strip 1. Use the folding positioning mechanism to press and fix the strip 1 at the first end. Use the linear drive assembly to control the moving end of the swing arm to move away from the stacking table, so that the distance between the first guide roller group 13 and the stacking table 10 increases to a set value, such as... Figure 17 As shown; taking the plane passing through the axis of the rotating shaft 12 and perpendicular to the stacking table 10 as the reference plane, the angle between the swing arm 11 and the reference plane reaches the maximum positive value at this time;

[0119] Sheets are stacked on a stacking table using a sheet stacking mechanism; specifically, a sliding seat is driven to move above the stacking table, and a moving seat is driven to move downward using a first driving mechanism to stack the sheet on the top layer of already folded strip. Then, the moving seat is driven to move upward to a set position, and the sliding seat is driven to move above the sheet conveying mechanism.

[0120] 2) such as Figure 18 As shown, the linear drive assembly drives the moving end 111 of the swing arm 11 to move away from the stacking table 10, while the swing drive assembly drives the swing arm 11 to rotate around the rotating shaft 12, 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 rotational motion of the swing arm around the rotating shaft, the swing end of the swing arm moves relative to the stacking table toward the second end of the reciprocating folding of the material.

[0121] 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 toggle block or an auxiliary motor. Then, the moving end of the swing arm is driven to move closer to the stacking table by the linear drive assembly, while the swing drive assembly drives the swing arm to rotate around the axis, so that the angle between the swing arm and the reference plane increases 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 towards the second end of the reciprocating folding of the material relative to the stacking table.

[0122] During this process, the sheet material 2 is transported to the position near the stacking table using the sheet material conveying mechanism; specifically, the sheet material is transported to the position near the stacking table using the sheet material conveying mechanism and corresponds to the position of the suction cup; then the moving seat is driven to move downward, and after the suction cup picks up the sheet material, the moving seat is driven to reset upward.

[0123] 3) 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. Figures 10-12 As shown; then, the moving end of the swing arm is driven by the linear drive assembly to move away from the stacking table, so that the distance between the first guide roller group 13 and the stacking table 10 increases to a set value, as shown. Figure 19 As shown;

[0124] Sheets are stacked on a stacking table using a sheet stacking mechanism; specifically, a sliding seat is driven to move above the stacking table, and a moving seat is driven to move downward using a first driving mechanism to stack the sheet on the top layer of already folded strip. Then, the moving seat is driven to move upward to a set position, and the sliding seat is driven to move above the sheet conveying mechanism.

[0125] 4) The swing arm is driven to rotate around the axis using a swing drive assembly, 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 towards the first end of the reciprocating folding of the material. 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. Afterward, the moving end of the swing arm is driven to move closer to the stacking table using a linear drive assembly, 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. Figure 20 As shown;

[0126] During this process, the sheet material 2 is transported to the position near the stacking table using the sheet material conveying mechanism; specifically, the sheet material is transported to the position near the stacking table using the sheet material conveying mechanism and corresponds to the position of the suction cup; then the moving seat is driven to move downward, and after the suction cup picks up the sheet material, the moving seat is driven to reset upward.

[0127] 5) When the swing end of the swing arm and the first guide roller group reach the end position of the first end of the tape reciprocating folding, the angle between the swing arm and the reference plane reaches its maximum positive value. The folding positioning mechanism presses and fixes the tape at the first end. Then, the linear drive assembly drives the moving end of the swing arm to move away from the stacking table, increasing the distance between the first guide roller group 13 and the stacking table 10 to the set value, such as... Figure 21 As shown;

[0128] 6) Repeat steps 2 to 5 until the stacking is complete.

29. A method for sheet-strip co-stacking, characterized in that: The reciprocating folding mechanism drives the strip material to fold back and forth on the stacking table. During the process of the reciprocating folding mechanism driving the strip material to move from one end of the reciprocating folding to the other end, the sheet material conveying mechanism conveys the sheet material to a position near the stacking table. The reciprocating folding mechanism drives the strip material from one end of the reciprocating folding to the other end, and the folding positioning mechanism is used to position it, completing one fold of the strip material. Then, the sheet material transfer mechanism is used to stack the sheet material located next to the stacking table on top of the strip material that has been folded on the stacking table. After the sheet material is stacked, the reciprocating folding mechanism drives the strip material to move towards the other end of the reciprocating folding, and this cycle is repeated until the stacking is completed. The reciprocating folding mechanism includes a folding guide mechanism and a folding drive mechanism. The folding guide mechanism includes a swing arm with a moving end and a swinging end at its two ends. The moving end of the swing arm is rotatable relative to a rotating shaft, and the swinging end is provided with a first guide roller group for guiding the material. The folding drive mechanism includes a drive component for driving the moving end of the swing arm to move along a preset track and a swing component for driving or guiding the swing arm to rotate around the rotating shaft. The preset track includes at least one vertical track perpendicular to the stacking table. The first guide roller group reciprocates relative to the stacking table under the combined motion of the moving end of the swing arm moving along a direction perpendicular to the stacking table and the rotational motion of the swing arm around the rotating shaft, so as to fold the material back and forth on the stacking table. Includes the following steps: 1) Position the swing end of the swing arm and the first guide roller at the end of the first end of the reciprocating folding of the strip. Use the folding positioning mechanism to press and fix the strip at the first end. Use the linear drive assembly to control the moving end of the swing arm to move away from the stacking table, so that the distance between the first guide roller group and the stacking table increases to the set value. Sheets are stacked on a stacking table using a sheet stacking mechanism; 2) 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, so that the angle between the swing arm and the reference plane is reduced. 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. 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. Then, 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, so that the angle between the swing arm and the reference plane increases 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 towards the second end of the reciprocating folding of the material relative to the stacking table. During this process, the sheet material is transported to the position near the stacking table using a sheet material conveying mechanism; 3) 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 included angle between the swing arm and the reference plane reaches the maximum value in the opposite direction. The folding positioning mechanism is used to press and fix the strip at the second end. Then, the linear drive assembly is used to drive the moving end of the swing arm to move away from the stacking table, so that the distance between the first guide roller group and the stacking table increases to the set value. Sheets are stacked on a stacking table using a sheet stacking mechanism; 4) The swing arm is driven to rotate around the axis by the swing drive assembly, which reduces 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. When the angle between the swing arm and the reference plane is reduced to zero, the distance between the moving end of the swing arm and the stacking table reaches its maximum value. After that, the moving end of the swing arm is driven to move toward the stacking table by the linear drive assembly, while the swing drive assembly is driven to rotate around the axis, which increases 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 toward the first end of the reciprocating folding of the material. During this process, the sheet material is transported to the position near the stacking table using a sheet material conveying mechanism; 5) 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 included angle between the swing arm and the reference plane reaches the maximum positive value. The folding positioning mechanism is used to press and fix the strip at the first end. Then, the linear drive assembly is used to drive the moving end of the swing arm to move away from the stacking table, so that the distance between the first guide roller group and the stacking table increases to the set value. 6) Repeat steps 2 to 5 until the stacking is complete.

The movable base is provided with a horizontal slide rail, and a sliding seat that slides with the horizontal slide rail is provided with the horizontal slide rail. A suction cup is arrayed on the bottom surface of the sliding seat. The movable base is provided with a second drive mechanism for driving the sliding seat to reciprocate between the stacking table and the sheet material conveying mechanism along the horizontal slide rail. In steps 1) and 3), the sliding seat is driven to move above the stacking table, and the moving seat is driven to move downward using the first driving mechanism to stack the sheet material on the top layer of the already folded strip material. Then, the moving seat is driven to move upward to the set position, and the sliding seat is driven to move above the sheet material conveying mechanism. In steps 2) and 4), the sheet material is conveyed to a position near the stacking table and corresponds to the position of the suction cup using the sheet material conveying mechanism; then the moving seat is driven to move downward, and after the suction cup picks up the sheet material, the moving seat is driven to reset upward.
