Description

Technical Field

[0001] This invention belongs to the field of battery cell stacking technology, and particularly relates to a stacking device with a film-coating and adhesive tape application function. Background Technology

[0002] Numerous stacking devices exist in the prior art, such as CN201210303599.7, which describes an alternating pressing stacking table device. This device includes four sets of clamping claw mechanisms distributed at both ends of the stacking table. Each pair of clamping claw mechanisms alternately acts on one end of the stacking table panel. Each set of clamping claw mechanisms includes two clamping claws for clamping the two corners of the electrode, a clamping claw cylinder for moving the clamping claws up and down, and a movable seat that mounts the clamping claw cylinder and the clamping claws and is connected to a moving mechanism. The device also includes two sets of moving mechanisms, each driving two sets of clamping claw mechanisms to alternately approach or move away from the stacking table. The moving mechanism includes a horizontal slide rail below the stacking table panel for mounting the clamping claw mechanisms, a rack connecting the clamping claw mechanisms, a gear shaft driving the rack to move horizontally, and a servo motor driving the gear shaft to rotate. The device also includes a filling mechanism for filling the clamping claw grooves on the stacking table panel. The filling mechanism includes a filling plate with an area close to the groove and a filling cylinder for pushing the filling plate. Its advantages are: two sets of clamping claw mechanisms alternately press the electrode sheets, saving time and achieving high stacking efficiency. CN201910642631.6, a die-cutting stacking system and method. The system includes an unwinding mechanism, an electrode roll cutting mechanism, a preheating roller pressing device, a detection device, a diaphragm cutting mechanism, and a stacking device. The negative electrode cutting mechanism cooperates with the negative electrode unwinding mechanism to cut the negative electrode sheet, and the positive electrode cutting mechanism cooperates with the positive electrode unwinding mechanism to cut the positive electrode sheet, resulting in a stack of negative and positive electrode sheets alternately distributed on the upper and lower sides of the diaphragm. The preheating roller pressing device causes the positive and negative electrode sheets of the stack to adhere to the diaphragm respectively. The detection device detects whether there are defects in the stack. The first diaphragm cutting mechanism cuts and discharges defective stacking units in pairs, and the second diaphragm cutting mechanism cuts the diaphragm of the last qualified stacking unit based on the number of stacking layers. The stacking device alternately stacks the positive and negative electrode stacking units. The system has a relatively simple structure, fast stacking speed, low failure rate, fewer diaphragm cutting times, and low risk of diaphragm wrinkles leading to external electrode leakage.

[0003] The above solutions achieve alternating stacking and diaphragm setup during stacking. However, these solutions cannot perform circumferential coating on the stacked cells with diaphragm setup, resulting in displacement between adjacent cells during transport. For example, Chinese patent 202220543362.5 discloses a cell composite electrode coating and stacking integrated machine, including a machine base. The machine base is equipped with a stacking mechanism, an electrode storage and feeding mechanism, a composite electrode coating mechanism, a composite electrode transport mechanism, a hot pressing station, a unloading robot, and a cell unloading station. The composite electrode coating mechanism, after completing the composite coating, transports the electrode to the unloading station via hot pressing and laser slicing. The composite electrode transport mechanism transports the laser-sliced ​​electrode to the electrode storage and feeding mechanism for storage. The unloading robot transports the stacked cells to the hot pressing station for hot pressing. The cell unloading station is equipped with a cell unloading mechanism that outputs the hot-pressed cells. The composite electrode coating mechanism includes a four-station turntable and a coating mechanism. The coating mechanism includes an electrode feeding fixture, a pre-composite platform, a pre-composite pressure plate mechanism, a film unwinding mechanism, a film stretching mechanism, and a film cutting mechanism. The electrode feeding fixture simultaneously lifts multiple electrode sheets for feeding, and the pre-composite pressure plate mechanism moves to directly above the electrode feeding fixture to pick up multiple electrode sheets. The film-pulling mechanism in this scheme pulls out the diaphragm from the film unwinding mechanism and lays the diaphragm on the pre-composite platform. The pre-composite pressing plate mechanism moves multiple electrode sheets to the top of the pre-composite platform and presses the electrode sheets onto the diaphragm. The film-cutting mechanism cuts the diaphragm to a fixed length. One side of the pre-composite platform is provided with a cover plate that can be flipped over to cover the pre-composite platform. The cover plate drives the diaphragm to flip over and cover the upper surface of the multiple electrode sheets, thus completing the coating of the multiple electrode sheets. This cell composite electrode sheet coating and stacking integrated machine has low coating efficiency, and after stacking, manual tape application is required on the corresponding circumferential sides of the stacked sheets to prevent stack displacement. Manual tape application requires applying tape of a set length to the corresponding side of the stacked sheets, which is not only inefficient but also results in poor tape application quality consistency. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a laminating device with a film-coating and adhesive tape application function that can solve the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A lateral tape application mechanism for applying tape to the sides of the laminated sheets.

[0009] There are two lateral grippers for the stacked plates, and both lateral grippers for the stacked plates are connected to the same rotary drive power.

[0010] In the aforementioned laminating equipment with film-coating and adhesive tape application function, the telescopic pressure roller assembly is located above the center position of the two laminating lateral grippers.

[0011] In the above-mentioned stacking equipment with film coating and adhesive tape application function, the telescopic pressure roller assembly includes a roller rotatably connected to the lifting frame, the lifting frame is connected to the fixed frame through a lifting guide pair, and a lifting driver for driving the lifting frame to rise and fall is provided on the fixed frame.

[0012] In the aforementioned laminating equipment with film-coating and tape-applying function, the rotary drive power includes a rotary drive shaft rotatably connected to the fixed frame, the two laminating side grippers are respectively connected to the rotary drive shaft through a first transmission structure, and the rotary drive shaft is connected to a rotary drive motor through a second transmission structure.

[0013] In the above-mentioned stacking device with film-coating and adhesive tape application function, the fixed frame is provided with two sliding seats that move relative to the fixed frame. The sliding seats are connected to a sliding driver. Each sliding seat is rotatably connected to a stacking side gripper. Each sliding seat and the rotary drive shaft are provided with a linkage structure that can drive the first transmission structure to slide axially on the rotary drive shaft when the sliding driver drives the sliding seat to slide.

[0014] In the aforementioned laminating device with film-coating and adhesive tape application function, the linkage structure includes an axially sliding sleeve that is axially slidably connected to the rotary drive shaft and circumferentially fixedly connected. An annular track groove is provided in the circumference of the axially shifting sleeve. A rotating wheel is rotatably connected to the sliding seat. The rotating wheel is located in the annular track groove and the rotating wheel and the groove wall of the annular track groove are in rotational contact. The first transmission structure is provided between the axially shifting sleeve and the laminating side gripper.

[0015] A rotary overlay lamination method, comprising a rotary overlay lamination mechanism, and comprising the following steps:

[0016] S10. The laminate is held by two lamination side grippers from opposite sides, and the lamination film is tightened during lamination.

[0017] The two lateral grippers of S11 and S10 rotate simultaneously. According to the rotation direction, the coating is continuously applied to the corresponding surface of the stack. The telescopic pressure roller assembly continuously rolls on the outer surface of the coating already covering the stack in the direction of stack rotation, thus completing the coating on the stack.

[0018] In the aforementioned lamination equipment with film-coating and tape-applying function, the lamination side tape-applying mechanism includes a mounting frame fixed on the machine base. A transverse drive assembly is provided on the mounting frame. An elastic component is provided on the transverse drive assembly, with its elastic extension direction perpendicular to the transverse drive direction of the transverse drive assembly. Two parallel clamping arms spaced vertically apart are connected to the elastic component, and an elastic clamping opening smaller than the total thickness of the laminate is formed between the two clamping arms. The opposite ends of the two clamping arms each have a tape-applying plane. A clamping roller assembly located in the elastic clamping opening is provided on each clamping arm. The clamping roller assembly located on the upper clamping arm protrudes from the lower surface of the clamping arm, and the clamping roller assembly located on the lower clamping arm protrudes from the upper surface of the clamping arm.

[0019] In the above-mentioned stacked lateral tape application mechanism, the two tape application planes are respectively provided with inclined surfaces on their opposing sides, and the two inclined surfaces are symmetrically distributed with respect to the central plane of the two clamping arms.

[0020] In the above-mentioned stacked sheet side-applying tape mechanism, a wheel assembly receiving groove is provided on one end of the clamping arm near the elastic clamping port, and the clamping roller assembly is rotatably installed in the corresponding wheel assembly receiving groove.

[0021] In the above-mentioned stacked lateral tape application mechanism, the clamping roller group includes at least one friction rotating wheel partially placed in the wheel group receiving groove. The axial ends of the friction rotating wheel are rotatably connected to the groove wall of the wheel group receiving groove, and a portion of the circumferential surface of the friction rotating wheel protrudes from the groove opening of the wheel group receiving groove. The friction rotating wheels provided on the two clamping arms are symmetrically distributed one above the other.

[0022] In the above-mentioned stacked lateral tape application mechanism, at least one blind hole extending along the length direction of the clamping arm is provided on each of the tape application planes.

[0023] In the above-mentioned stacked lateral tape application mechanism, the elastic component is a vertical elastic component. The elastic component includes a follower seat fixed to the lateral drive component, a vertical guide rod on the follower seat, a guide hole for the vertical guide rod to pass through on the clamping arm, an upper elastic component between the upper surface of the clamping arm and the follower seat, and a lower elastic component between the lower surface of the clamping arm and the follower seat. The upper elastic component and the lower elastic component are distributed along the same track.

[0024] In the above-mentioned stacked lateral tape application mechanism, the elastic force of the upper elastic component is equal to the elastic force of the lower elastic component, and a central elastic component is also provided between the two clamping arms. The elastic force of the central elastic component is less than the elastic force of the upper elastic component.

[0025] In the above-mentioned stacked lateral tape application mechanism, the lateral drive assembly includes a cantilever plate fixed on the mounting frame, a lateral drive is provided on the upper surface of the cantilever plate, the output end of the lateral drive is connected to the follower seat, and a lateral guide pair is provided between the cantilever plate and the follower seat.

[0026] In the above-mentioned stacked lateral tape application mechanism, the stacked lateral tape application mechanism further includes a tape unwinding assembly, an upper clamping assembly, and a vertical traction clamping assembly installed sequentially from top to bottom on the mounting frame, as well as a cutting assembly that cuts the tape when the upper clamping assembly and the vertical traction clamping assembly are vertically taut and adhered to the tape application surface.

[0027] In the above-mentioned stacked lateral tape application mechanism, the cutting assembly includes a cutting blade that is inclinedly distributed on a horizontal plane. The cutting blade is connected to a cutting translation drive device, which drives the cutting blade to cut from one side of the tape to the other side of the tape.

[0028] A method for applying adhesive tape to stacked sheets laterally, wherein the method employs the aforementioned mechanism for applying adhesive tape to stacked sheets laterally, and the method includes the following steps:

[0029] S1. The unwound tape is vertically stretched and adhered to the tape adhesion surface of the two clamping arms;

[0030] S2, Cut the upper end of the tape stretched in S1, and after cutting, let the lower end of the cut tape be unclamped;

[0031] S3. Under the drive of the transverse drive assembly, the two clamping arms cause the middle part of the tape that was stuck on the adhesive tape surface in S2 to first contact and stick to the side of the stacked sheet. As the transverse drive assembly continues to drive, the two ends of the tape are folded and stuck to the two surfaces in the thickness direction of the stacked sheet.

[0032] The stacked sheet has multiple lateral directions in its circumferential direction. By rotating the stacked sheet and repeating the above steps S1-S3, the corresponding lateral directions of the stacked sheet are processed by applying adhesive tape.

[0033] In the aforementioned stacked sheet side-applying tape mechanism, a rotary sheet-carrying robot is slidably connected to the machine base. The rotary sheet-carrying robot is used to obtain the stacked sheets after being stacked by the alternating stacking mechanism and transfer them to the rotary covering stacked sheet laminating mechanism. The rotary sheet-carrying robot is also used to obtain the stacked sheets after being laminating by the rotary covering stacked sheet laminating mechanism and transfer them to the stacked sheet side-applying tape mechanism. A discharge storage station is provided on the machine base. After obtaining the stacked sheets with side-applying tape, the rotary sheet-carrying robot stacks the stacked sheets in the discharge storage station. The aforementioned rotation of the stacked sheets is achieved by a stacking sheet clamping rotation station slidably disposed on the machine base. The stacking sheet clamping rotation station is slidably connected to the machine base. The machine base is provided with a station driver that drives the stacking sheet clamping rotation station to move. The station driver is a power source such as a pneumatic cylinder or a hydraulic cylinder. The stacking sheet clamping rotation station includes a lower fixed fixture and an upper movable pressure plate. The upper movable pressure plate moves downward under the action of a lifting drive cylinder. The stacked sheets after rotation and coating are pressed between the lower fixed fixture and the upper movable pressure plate. Then, the lower fixed fixture rotates under the action of a rotation drive power so that the corresponding side of the stacked sheets is located beside the elastic clamping port.

[0034] Compared with existing technologies, the advantages of this application are:

[0035] Achieving 360° coating using a rotary coating method not only simplifies the structure but also improves coating efficiency. It also prevents displacement of stacked monomers during adsorption and handling, as well as during post-processing.

[0036] Side-applying tape, through mechanized and automated operation, improves efficiency and reduces costs.

[0037] The elastic component forces the elastic clamping opening formed by the two clamping arms to have a vertical diameter smaller than the total thickness of the stack. When the clamping rollers on the corresponding clamping arms contact the stack, the elastic component is compressed. As the transverse drive component continues to drive, the tape adheres to the corresponding surface in the thickness direction of the stack under the pressure of the clamping rollers. This not only improves processing efficiency but also ensures the stability and firmness of the bonding quality of different stacks in different lateral directions, significantly reducing production costs.

[0056] The following are specific embodiments of the invention, which are described in conjunction with the accompanying drawings. The technical solution of the invention will be further described, but the invention is not limited to these embodiments.

[0057] See the lamination and tape application process. Figure 1 and Figure 3 And see the state of the tape being applied to the back side of the stacked sheets. Figure 2 .

[0058] Example 1

[0059] Based on the appendix Figures 1-3 As shown, Figures 4-6 As shown, this laminating equipment with film coating and tape application function includes a machine base 1, a film coating unwinding mechanism 2 on the machine base 1, and an alternating laminating mechanism a for stacking multiple laminated units, and the film unwinding mechanism 2 separates adjacent upper and lower laminated units stacked by the alternating laminating mechanism a to form a laminate.

[0060] The film unwinding mechanism 2 of this embodiment includes a film roll core 20 and a plurality of unwinding tension rollers 21 arranged in the unwinding direction, wherein two unwinding tension rollers 21 are on the same horizontal plane.

[0061] The alternating stacking mechanism a in this embodiment includes a stacking moving platform a1, which is slidably connected to a machine base 1. A translational drive power source is provided on the machine base 1 to drive the stacking moving platform a1 to translate. The sliding motion can be achieved, for example, by a guide rail pair. The translational drive power source can be any one of a cylinder, a hydraulic cylinder, or a linear motor. A front pressing claw group a2 and a rear pressing claw group a3 are provided in the sliding direction of the stacking moving platform a1. When the stacked units are alternately stacked on the stacking moving platform a1, the platform a1 moves back and forth between the front pressing claw group a2 and the rear pressing claw group a3. At the corresponding position, the front pressing claw group a2 or the rear pressing claw group a3 presses down on the stacked units, so that the coating can cover the thickness surface of the upper and lower stacked units. The front pressing claw group a2 and the rear pressing claw group a3 can also be understood as left and right claw groups.

[0062] The front tablet pressing claw assembly a2 and the rear tablet pressing claw assembly a3 have the same structure, including symmetrically distributed pressing plates. The pressing plates are connected to a lifting drive cylinder, which can be replaced by a hydraulic cylinder. The two pressing plates of the front tablet pressing claw assembly a2 and the two pressing plates of the rear tablet pressing claw assembly a3 move up and down simultaneously.

[0063] like Figures 4-6As shown, the alternating stacking mechanism a also includes two stacking unit hoppers a4 located beside the stacking moving platform a1. The stacking unit hoppers a4 are lifting hoppers, lifting the stacked units in a4 upwards to facilitate the unit manipulators a6 in acquiring and transferring them to their respective transfer platforms a5. The unit manipulators a6 are suction cup-type multi-axis moving manipulators, for example, with vertical and translational axes. The stacked units on the transfer platform a5 are acquired by the two manipulators corresponding to the front pressing claw group a2 and the rear pressing claw group a3 and transferred to the stacking moving platform a1, at which point stacking begins on the stacking moving platform a1. The unwound coating first covers the upper surface of the first stacked unit placed on the stacking moving platform a1. Due to the forward / backward or left / right movement of the stacking moving platform a1, the coating covers the continuously stacked stacked units in a serpentine trajectory.

[0064] like Figures 7-11 As shown, this laminating equipment with film coating and tape application function also includes a rotary covering laminating and film coating mechanism b and a laminating and side tape application mechanism c. The rotary covering laminating and film coating mechanism b is used to clamp the laminated sheets and drive them to rotate, at which time the film coating forms at least 360° of coverage on the laminated sheets. After the coating is completed, it is necessary to cut the coated laminated sheets and the continuously unwound and tensioned film. A cutting blade assembly 3 with rollers is provided on the machine base 1. During the coating stage, the blades 30 of the cutting blade assembly 3 do not contact the film coating, while the film coating only contacts the rollers 31 of the cutting blade assembly 3. After the coating is completed, the blades cut the film downwards under the action of the lifting drive power 34, which is a cylinder. The roller 31 is mounted on the lifting frame 33, which is connected to the frame lifting cylinder 32. When the blade is cutting, the frame lifting cylinder 32 drives the roller 31 to descend and press the film onto the stacking moving platform a1. That is, the stacking moving platform a1 moves to below the roller 31.

[0065] The rotary covering laminating mechanism (b) achieves 360° full lamination of the stacked sheets, providing an overall circumferential limiting effect and improving the regularity of the stacked sheet's outer contour. It not only has a simple structure but also improves lamination efficiency and prevents displacement of individual stacked sheets during adsorption, handling, and post-processing. Simultaneously, the same rotary drive power propels two sets of lateral clamping jaws to rotate synchronously, maintaining equal rotational angular velocities to ensure consistent lamination quality on both sides of the stacked sheet. Furthermore, a telescopic pressure roller assembly first continuously rolls and adheres the film to the stacked sheet surface in the center, then relies on the film's own surface adhesion to spread and adhere from the center to both sides, thereby expelling air from the gaps to both sides. This ensures external stability of the lamination, improves the flatness of the film on the outer surface of the stacked sheet, eliminates internal air bubbles and wrinkles, and avoids the problem of easy breakage of protruding surfaces during later lamination.

[0066] The rotary covering laminated film mechanism b includes a fixed frame b1, which serves as an equipment platform or a shared installation platform with other components, acting as a carrier for component installation.

[0067] The laminated structure consists of several laminated units stacked vertically at intervals. The film is wound onto a film-coating mandrel 20. The unwound film first covers the surface of the first laminated unit placed at the bottom, and then covers the continuously stacked laminated units in a serpentine pattern. The width of the film is greater than the width of the laminated units. There is a gap between the film-coating mandrel 20 and the laminated side grippers b2, so the part of the structure with the film between the film-coating mandrel 20 and the laminated side grippers b2 is in a flat state and remains taut.

[0068] like Figures 7-12 As shown, two sets of symmetrically arranged lateral grippers b2 are rotatably connected to the fixed frame b1 for clamping the stacked sheets at their respective edges. In this embodiment, each set of lateral grippers b2 includes a gripping cylinder rotatably connected to the fixed frame b1. A clamping plate b21 is connected to each of the two gripping cylinders. The clamping plates b21 are arranged along the edges of the stacked sheets. Driven by the clamping cylinder, the clamping plates b21 on the same side clamp the upper and lower ends of one side of the stacked sheet, achieving clamping and limiting of the stacked sheets and improving the fixing foundation for rotating and coating the stacked sheets.

[0069] Two sets of lateral grippers b2 are connected to the same rotary drive power b4. Specifically, the rotary drive power b4 includes a rotary drive power b40 rotatably connected to the fixed frame b1. The two sets of lateral grippers b2 are respectively connected to the rotary drive power b40 through a first transmission structure b41, which can be either belt drive or chain drive. The rotary drive power b40 is connected to a rotary drive motor b43 through a second transmission structure b42, which can be either belt drive, chain drive, or gear drive. In this embodiment, both the first transmission structure b41 and the second transmission structure b42 use belt drive. The rotary drive motor b43 drives the rotary drive power b40 to rotate through the second transmission structure b42, and then transmits the power to the lateral grippers b2 through the two sets of first transmission structures b41 spaced apart on the rotary drive power b40. This completes the synchronous flipping of the lateral grippers b2, causing the flat-laid film to rotate and adhere to the outer circumference of the lateral grippers b2 at least one revolution. In this embodiment, a rotary coating method is used to achieve 360° coating of the stacked sheets, realizing an overall circumferential limiting effect on the stacked sheets, improving the regularity of the stacked sheet's outer contour, simplifying the structure, increasing coating efficiency, and preventing displacement of individual stacked sheets during adsorption, handling, and post-processing. Simultaneously, the same rotary drive b4 drives the two sets of lateral grippers b2 to rotate synchronously, maintaining equal rotational angular velocities to ensure consistent coating quality on both sides of the stacked sheets during rotation.

[0070] The fixed frame b1 is equipped with two sliding seats b50 that move relative to the fixed frame b1. The sliding seats b50 are connected to a sliding driver b51, which is a cylinder. Each sliding seat b50 is rotatably connected to a set of stacking lateral grippers b2. The sliding driver b51 drives the sliding seat b50 to move the stacking lateral grippers b2, thereby adjusting the distance between the two stacking lateral grippers b2. This prevents interference between the stacking, the coating and the stacking lateral grippers b2 when the stacking enters or leaves the stacking lateral grippers b2, thus avoiding entanglement problems.

[0071] To ensure that the lateral gripper b2 of the stacked sheets can perform rotation and translation operations respectively, a linkage structure b6 is provided between each sliding seat b50 and the rotary driving power b40. When the sliding driver b51 drives the sliding seat b50 to slide, it can drive the first transmission structure b41 to slide axially in the rotary driving power b40.

[0072] like Figures 7-11 As shown, in this embodiment, the linkage structure b6 includes an axially sliding sleeve b60 that is axially slidably connected to the rotary drive power b40 and circumferentially fixedly connected. An annular track groove b61 is provided circumferentially on the axially shifting sleeve b60. A rotating wheel b62 is rotatably connected to the sliding seat b50. The rotating wheel b62 is located in the annular track groove b61, and the rotating wheel b62 and the groove wall of the annular track groove b61 are in rotational contact. A first transmission structure b41 is provided between the axially shifting sleeve b60 and the stacked piece lateral gripper b2. During the translation of the stacked piece lateral gripper b2 via the linkage structure b6, the first transmission structure b41 is driven to move synchronously, preventing translational misalignment in the connection of the first transmission structure b41.

[0073] When the sliding actuator b51 drives the lateral gripper b2 of the stacked pieces to move, the sliding seat b50 will drive the rotating wheel b62 placed in the annular track groove b61 to move together. The axial displacement sleeve b60 can only move axially with the rotary driving force b40 and will not rotate circumferentially relative to the rotary driving force b40. At this time, it can drive the first transmission structure b41 to move as a whole to adjust the relative position of the two lateral grippers b2 of the stacked pieces. When the rotary driving force b40 is driven, it drives the axial displacement sleeve b60 to rotate together. The first transmission structure b41 is connected to the axial displacement sleeve b60, so the first transmission structure b41 can also transmit the rotational power of the rotary driving force b40 to the lateral gripper b2 of the stacked pieces, so that the lateral gripper b2 of the stacked pieces rotates. And since the rotating wheel b62 and the annular track groove b61 are in rotational contact, the following rotation of the axial displacement sleeve b60 forces the rotating wheel b62 to rotate relative to the annular track groove b61.

[0074] The sliding seat b50, together with the sliding driver b51, the annular track groove b61, and the rotating wheel b62, can keep the first transmission structure b41 in a stable transmission state.

[0075] Axial sliding connections and circumferential fixed connections can be achieved using flat keys and keyways. This structure is a standard design in transmission devices, so it will not be elaborated upon here.

[0076] The sliding seat b50 is provided with an extension plate b63 extending towards the axial displacement sleeve b60. The rotating wheel b62 is connected to one end of the extension plate b63 near the axial displacement sleeve b60 via a rotating shaft. The extension plate b63 increases the protruding structure of the rotating wheel b62 to ensure that the rotating wheel b62 can be embedded into the annular track groove b61 without interference.

[0077] It is conceivable that the linkage structure b6 can also be set on the annular track disk with the axial displacement sleeve b60, and two rotating wheels b62 are connected at intervals on the extension plate b63. ​​The two rotating wheels b62 abut against the two sides of the annular track disk respectively. This outward-convex linkage method achieves the same effect as the rotating wheels b62 being embedded in the annular track groove b61.

[0078] like Figures 7-12 As shown, the rotary covering lamination mechanism further includes a telescopic pressure roller assembly b3 that is continuously tangential to the corresponding surfaces of the laminations rotated by the lateral grippers b2. The telescopic pressure roller assembly b3 is used to continuously roll the laminations onto the outer surface of the film already covered on the laminations in the direction of rotation. In this embodiment, the telescopic pressure roller assembly b3 is located above the central position of the two sets of lateral grippers b2. The two sets of lateral grippers b2 and the telescopic pressure roller assembly b3 are arranged in an isosceles triangle. This ensures balanced force on the laminations and prevents deformation. It is conceivable that the telescopic pressure roller assembly b3 can also be located below the central position of the two sets of lateral grippers b2. Similarly, the two sets of lateral grippers b2 and the telescopic pressure roller assembly b3 are arranged in an isosceles triangle, ensuring balanced force on the laminations and preventing deformation.

[0079] Specifically, the telescopic pressure roller assembly b3 includes a rolling roller b31 rotatably connected to the lifting frame b30. The lifting frame b30 is connected to the fixed frame b1 via a lifting guide pair b32. The fixed frame b1 is provided with a lifting driver b33, which drives the lifting frame b30 to move up and down. The lifting driver b33 is a cylinder. Before the lateral gripper b2 of the stacking sheet begins to rotate, the lifting driver b33 drives the lifting frame b30 to move up and down relative to the fixed frame b1 along the lifting guide pair b32 until one end of the rolling roller b31 abuts against the surface of the stacked sheet near the side of the sheet in the flat-laying state.

[0080] A cantilever block b34 is provided on the fixed frame b1, suspended above two sets of lateral grippers b2 for lamination. A lifting drive b33 is fixed on the cantilever block b34. A lifting guide pair b32 is movably connected to the cantilever block b34, and the lifting frame b30 is located below the cantilever block b34. The cantilever block b34 fixes the initial height of the telescopic pressure roller assembly b3, preventing the rolling roller b31 from interfering with the lateral grippers b2 for lamination before covering.

[0081] The lateral gripper b2 simultaneously holds and rotates the stacked sheets. In the direction of rotation, the film is continuously applied to the corresponding surfaces of the stacked sheets. One end of the roller b31 continuously rolls from the surface of the stacked sheets near the film-coated side in the flat state onto the outer surface of the film already covering the stacked sheets in the direction of stacked sheet rotation. When the roller b31 moves upward, the cylinder maintains the same pressure to achieve force-fitting and retraction. When the roller b31 moves downward, the cylinder pushes the roller b31 down to abut against the film surface.

[0082] The width of the rolling roller b31 is smaller than the width of the clamping station formed between the two sets of lateral grippers b2. It can be imagined that the two sides of the film are covered on the surface of the lateral grippers b2, with gaps between them and the surface of the film. The rolling roller b31 first rolls and applies the middle part of the film to the surface of the film along the center position. Then, relying on the surface adhesion of the film itself, it spreads and adheres from the center to both sides, thereby expelling the air in the gaps to both sides. This forms an external limit during the film application process, ensuring the external stability of the film application, improving the flatness of the film on the outer surface of the film, eliminating internal air bubbles and wrinkles, and avoiding the problem of easy damage to the protruding surface of the film in the later stage. When the lamination is a regular film, after the lamination is completed, the lateral gripper b2 of the stack can extend beyond the film-covered surfaces on both sides of the stack by translating. When the lamination is a release film, the adhesive surface of the release film always faces the surface of the stack. The lateral gripper b2 of the stack is made of anti-adhesion material, which makes it easy for the lateral gripper b2 of the stack to extend beyond the film-covered surfaces on both sides of the stack by translating after the lamination is completed.

[0083] A cutting blade assembly 3 with rollers is installed above the flat-laid film. During the wrapping stage, the blades of the cutting blade assembly 3 do not contact the film, while the film only contacts the rollers of the cutting blade assembly 3. After wrapping, the blades cut the film downwards under the action of a lifting drive power, which is a cylinder. The rollers are mounted on a lifting frame, which is connected to a lifting cylinder. After the film is cut, the remaining material is wound around the outside of the stack, and the telescopic pressure roller assembly b3 completes the wrapping.

[0084] like Figures 7-12As shown, the rotary covering method for laminating sheets includes the following steps: S10, the sheets are clamped from opposite sides by two lateral clamping jaws b2, and the film is stretched during lamination; S11, the two lateral clamping jaws b2 in S10 rotate simultaneously, and the film is continuously applied to the corresponding surfaces of the sheets in the direction of rotation, and the telescopic pressure roller assembly b3 continuously rolls on the outer surface of the film already applied to the sheets in the direction of sheet rotation, thus completing the application of the film to the sheets.

[0085] During the lamination process, the stacked sheets are held stably, and there is no interference during the rotational lamination process. Simultaneously, the telescopic pressure roller assembly b3 is used to roll and form external limit fixation, which further improves the lamination efficiency and lamination flatness.

[0086] like Figures 14-18 As shown, the stacked lateral tape application mechanism c includes a mounting frame c1, which has a vertical plate-like or frame-like structure.

[0087] A transverse drive assembly c2 is provided on the mounting frame c1. Specifically, the transverse drive assembly c2 in this embodiment includes a cantilever plate c20 fixed on the mounting frame c1. A transverse driver c21 is provided on the upper surface of the cantilever plate c20. The transverse driver c21 can be any one of a cylinder, a hydraulic cylinder, and a linear motor.

[0088] The transverse drive assembly c2 is provided with an elastic component c3 whose elastic extension direction is perpendicular to the transverse drive direction of the transverse drive assembly c2. For example, the transverse direction is horizontal, while the elastic extension direction is vertical. Two parallel clamping arms c4 are connected to the elastic component c3, and an elastic clamping opening c0 smaller than the total thickness of the stack is formed between the two clamping arms c4. That is, the diameter of the elastic clamping opening c0 in the vertical direction is smaller than the total thickness of the stack.

[0089] The two clamping arms c4 each have an adhesive tape bonding surface c40 at their opposite ends. The adhesive tape bonding surface c40 is adhesive to hold the adhesive tape. Of course, when the tape is being bonded and bent, the driving force must be greater than the adhesive force. The adhesive tape bonding surface c40 is a vertical surface. Each clamping arm c4 is provided with a clamping roller assembly c5 located in the elastic clamping opening c0. The clamping roller assembly c5 located on the upper clamping arm c4 protrudes from the lower surface of the clamping arm c4, and the clamping roller assembly c5 located on the lower clamping arm c4 protrudes from the upper surface of the clamping arm c4.

[0090] like Figures 14-18As shown, the elastic component c3 forces the elastic clamping opening c0 formed by the two clamping arms c4 to have a vertical diameter smaller than the total thickness of the stack. When the clamping roller group c5 on the corresponding clamping arm c4 contacts the stack, the elastic component c3 is compressed. As the transverse drive component c2 continues to drive, the tape adheres to the corresponding surface in the thickness direction of the stack under the pressure of the clamping roller group c5. This not only improves processing efficiency but also ensures the stability and firmness of the bonding quality of different stacks in different lateral directions, significantly reducing production costs.

[0091] In a preferred embodiment, the two tape-adhesive bonding surfaces c40 are each provided with an inclined surface c43 on their opposing sides, and the two inclined surfaces c43 are symmetrically distributed around the central plane of the two clamping arms c4. The inclined surface c43 allows the tape to be applied to smoothly enter the elastic clamping opening c0, while also preventing bending damage to the tape at the edges.

[0092] For example, the two inclined surfaces c43 are distributed in a figure-eight shape.

[0093] Secondly, a wheel assembly receiving groove c41 is provided at the end of one surface of the clamping arm c4 near the elastic clamping opening c0, and a clamping roller assembly c5 is rotatably installed in the corresponding wheel assembly receiving groove c41. The wheel assembly receiving groove c41 allows the clamping roller assembly c5 to be installed in a partially embedded manner, which can protect the clamping roller assembly c5, and at the same time, can shorten the extension length of the elastic component c3 in the vertical direction. In addition, the groove opening of the wheel assembly receiving groove c41 can limit the side edge of the tape when the tape is bent relative to the clamping roller assembly c5, so as to ensure the flatness of the tape during bending and pasting as much as possible. Specifically, the clamping roller assembly c5 in this embodiment includes at least one friction rotating wheel partially placed in the wheel assembly receiving groove c41. The axial ends of the friction rotating wheel are rotatably connected to the groove wall of the wheel assembly receiving groove c41, and a part of the circumferential surface of the friction rotating wheel protrudes from the groove opening of the wheel assembly receiving groove c41. The friction rotating wheels provided on the two clamping arms c4 are symmetrically distributed one above the other. The design of the friction rotating wheel can minimize mutual impact and wear when the friction rotating wheel contacts the stacked plates, ensuring that the stacked plates are free from scratches and other phenomena.

[0094] The friction rotating wheels rotate by friction, and the number of friction rotating wheels is 1-8. Here, the friction rotating wheels are distributed in a row with uniform intervals between each other.

[0095] To facilitate the installation of the friction rotating wheel, at least one long sidewall of the wheel assembly receiving groove c41 is a detachable baffle c44, and one end of the friction rotating wheel is rotatably connected to the baffle c44.

[0096] Secondly, each tape-adhesive surface c40 is provided with at least one blind hole c42 extending along the length of the clamp arm c4. When the tape is adhered to the tape-adhesive surface c40, the blind hole c42 is closed by the tape, making it less likely for the tape to fall off during transport.

[0097] Specifically, such as Figures 14-18 As shown, the elastic component c3 in this embodiment is a vertical elastic component. The elastic component c3 includes a follower seat c30 fixed to the transverse drive component c2. The follower seat c30 is U-shaped and rotated 90° counterclockwise. A vertical guide rod c31 is provided on the follower seat c30. The two ends of the follower seat c30 are fixed to the two end sections of the U-shaped seat. A guide hole is provided on the clamping arm c4 for the vertical guide rod c31 to pass through, i.e., the vertical guide rod c31 and the guide hole are loosely fitted. An upper elastic component c32 is provided between the upper surface of the upper clamping arm c4 and the follower seat c30, and a lower elastic component c34 is provided between the lower surface of the lower clamping arm c4 and the follower seat c30. The upper elastic component c32 and the lower elastic component c34 are distributed along the same track. The shared track of the upper elastic component c32 and the lower elastic component c34 ensures the symmetrical formation of the elastic force, thereby forming a relative adhesive pressure.

[0098] Secondly, both the upper elastic component c32 and the lower elastic component c34 are elastic components such as compression springs or springs. The upper elastic component c32 and the lower elastic component c34 can be independent of the vertical smooth rod c31, or they can be fitted onto the vertical smooth rod c31.

[0099] In a preferred embodiment, the elastic force of the upper elastic member c32 is equal to the elastic force of the lower elastic member c34. A central elastic member c35 is also provided between the two clamping arms c4, and the elastic force of the central elastic member c35 is less than the elastic force of the upper elastic member c32. Furthermore, the central elastic member c35 is located between the upper elastic member c32 and the lower elastic member c34, and all three are distributed along a common track.

[0100] The centrally located elastic component C35 is a compression spring or other elastic component.

[0101] Specifically, in this embodiment, the output end of the transverse drive c21 is connected to the follower seat c30, and a transverse guide pair c22 is provided between the cantilever plate c20 and the follower seat c30. The transverse guide pair c22 is a mating pair of guide rod and guide sleeve, or a mating pair of guide rail and slider, to improve the translational stability of the follower seat c30.

[0102] Also, such as Figures 14-18As shown, the stacking side-applying tape mechanism c also includes a stacking clamping rotary station c10 located beside the elastic clamping port c0. The stacking clamping rotary station c10 is slidably connected to the machine base 1. A station driver c11 is provided on the machine base 1 to drive the stacking clamping rotary station c10 to move. The station driver c11 is a linear drive assembly or a cylinder, etc. The driving direction of the station driver c11 is perpendicular to the sliding direction of the stacking moving platform a1. The station driver c11 drives the stacking clamping rotary station c10 to approach the sliding trajectory of the stacking moving platform a1, so that the stacked sheets can be transferred onto the stacking clamping rotary station c10. The stacking clamping rotation station includes a lower fixed fixture and an upper movable pressure plate. The upper movable pressure plate moves downward under the action of the lifting drive cylinder. The stacked sheets after rotation and coating are pressed between the lower fixed fixture and the upper movable pressure plate. Then, the lower fixed fixture rotates under the action of the rotation drive power so that the corresponding side of the stacked sheets is located next to the elastic clamping port.

[0103] A rotary sheet conveying robot 4 is slidably connected on the machine base 1. The rotary sheet conveying robot 4 is used to obtain the stacked sheets after the alternating stacking mechanism a is stacked and transfer them to the rotary covering stacking and film coating mechanism b. The rotary sheet conveying robot 4 is also used to obtain the stacked sheets after the film coating mechanism b is coated and transfer them to the stacking side tape application mechanism c. The machine base 1 is provided with a discharge storage station 5. After the rotary sheet conveying robot 4 obtains the stacked sheets with side tape application, it stacks the stacked sheets in the discharge storage station 5.

[0104] The rotary film transport robot 4 includes a gripper 40 and a rotary drive power source 41 for driving the gripper to rotate, such as a DD motor or an electric motor. The rotary film transport robot 4 is connected to the machine base 1 via a guide rail sliding pair 42, and the sliding power is a linear drive or a cylinder, etc.

[0105] This stacked side-applying tape mechanism also includes a tape unwinding assembly c6, an upper clamping assembly c7, and a vertical traction clamping assembly c8, which are installed sequentially from top to bottom on the mounting frame c1. It also includes a cutting assembly c9 that cuts the tape when it is vertically taut and adhered to the tape pasting plane c40 by the upper clamping assembly c7 and the vertical traction clamping assembly c8.

[0106] The tape unwinding assembly c6 includes a tape unwinding roller c60, a plurality of tape tensioning rollers c61 located below the tape unwinding roller c60, and at least one tape tensioning roller c61 connected to a tensioning driver c62 to make the tape unwinding tension adjustable. Some or all of the tape tensioning rollers c61 have annular friction protrusions on their surfaces to prevent slippage during unwinding and to increase friction.

[0107] like Figures 14-18As shown, the upper clamping assembly c7 includes an upper clamping wheel c70 and upper clamping blocks c71 spaced apart from the upper clamping wheel c70. The upper clamping blocks c71 have a tangent surface that is tangent to the circumferential surface of the upper clamping wheel c70. The upper clamping blocks c71 are connected to the upper clamping driver c72, which can be any one of a cylinder, a hydraulic cylinder, or a linear motor. The upper clamping driver c72 drives the upper clamping blocks c71 to approach the upper clamping wheel c70 to clamp the tape. For example, during cutting, the upper clamping assembly c7 and the vertical traction clamping assembly c8 can keep the tape taut. After the cutting assembly c9 completes the cutting, the upper clamping assembly c7 can clamp the unwinding outer end of the tape. At this time, the traction clamping assembly c8 approaches the upper clamping assembly c7 and clamps the outer end of the tape, and then pulls it downward. The cutting process described above is then repeated.

[0108] The vertical traction clamping assembly c8 includes a clamping finger cylinder c80, which is connected to a traction lifting driver c81. The traction lifting driver c81 can be any one of a cylinder, a hydraulic cylinder, or a linear motor. A clamping component c82 is provided on the corresponding clamping finger of the clamping finger cylinder c80. The clamping component c82 can be any one of a clamping wheel and a clamping block, or a combination of both. Preferably, it consists of one clamping wheel and one clamping block.

[0109] In order to make the finger-clamping cylinder C80 lift and lower more smoothly and stably, a vertical guide assembly is provided between the finger-clamping cylinder C80 and the mounting bracket 1. The vertical guide assembly is, for example, a guide rail pair or a guide rod pair.

[0110] The cutting assembly c9 includes a cutting blade c90 that is inclinedly distributed on a horizontal plane. The cutting blade c90 is connected to a cutting translation drive device c91, which drives the cutting blade c90 to cut from one side of the tape to the other side. The cutting translation drive device c91 can be any one of a cylinder, a hydraulic cylinder, or a linear motor. A protective cover c92 is provided on the mounting frame 1, which covers the cutting blade c90 in three dimensions. The cutting blade c90 moves horizontally within the protective cover c92, which is U-shaped.

[0111] The design of the cutter c90 allows the tape to be cut from one side to the other at a uniform speed. Combined with the U-shaped protective cover c92 with the opening facing the tape, the upper end of the cut tape is interfered with by the lower side of the protective cover c92 and will not curl or self-adhere.

[0112] Example 2

[0113] like Figures 14-18 As shown, this embodiment provides a method for applying adhesive tape to stacked sheets laterally. The method uses the stacked sheet lateral adhesive tape application mechanism of Embodiment 1, and includes the following steps:

[0114] S1. The unwound tape is vertically taut and adhered to the tape adhesion plane c40 of the two clamping arms c4; the tautness is the combined effect of the upper clamping assembly c7 and the vertical traction clamping assembly c8.

[0115] S2, Cutting the upper end of the taut tape in S1, and after cutting, the lower end of the cut tape is unclamped; that is, the cutting component c9 performs the cutting, and the vertical traction clamping component c8 unclamps.

[0116] S3. Driven by the transverse drive assembly c2, the two clamping arms c4 cause the middle part of the tape adhered to the tape bonding plane c40 in S2 to first contact and adhere to the side of the stack. As the transverse drive assembly c2 continues to drive, the two ends of the tape are folded and adhered to the two surfaces in the thickness direction of the stack. Since the elastic clamping opening c0 is smaller than the total thickness of the stack, the clamping arms c4 continue to advance, thereby changing the tape from the initial vertical state to the final U-shaped bonding state.

[0117] That is, the adhesive side of the unwound tape faces the stack of sheets.

[0118] The stacked sheets have multiple lateral directions. By rotating the stacked sheets and repeating steps S1-S3 above, the corresponding lateral directions of the stacked sheets are processed to apply adhesive tape. The rotating stacking method uses a rotary motor combined with a positioning fixture.

[0119] Example 3

[0120] Please see Figure 13 The structure and principle of this embodiment are basically the same as those of Embodiment 1, with the only difference being that an elastic element b35 is sleeved on the lifting guide pair b32, connecting the cantilever block b34 and the lifting frame b30. In this embodiment, the elastic element b35 is a spring. The spring can be connected to one side or both sides of the cantilever block b34. Through the elastic properties of the spring, the rolling roller b31 continuously rolls elastically onto the outer surface of the film already covered on the stacked sheets, achieving an elastic bonding effect of the rolling roller b31, replacing the bonding effect formed by the stroke drive of the lifting driver b33. This method improves the bonding effect of the rolling roller b31 and simplifies the complex stroke control devices such as the lifting driver b33 and sensors.
