Description

Technical Field

[0001] This invention relates to the field of automated equipment, and in particular to a rotating automatic stacking machine. Background Technology

[0002] With the country's vigorous promotion of new energy development, the demand for lithium-ion power batteries from all walks of life is increasing. The production process of lithium-ion power batteries involves the stacking of positive and negative electrode sheets to form an electrode assembly. During the stacking process, a separator needs to be inserted between adjacent positive or negative electrode sheets to block the flow. After being separated by the separator, the positive and negative electrode sheets are cross-stacked to form the battery's electrode assembly. The stacked electrode assembly needs to undergo a hot-pressing process for curing. After hot pressing, multiple strips of adhesive tape are wrapped around the four sides of the electrode assembly to secure it for subsequent processing. In the electrode lamination section, the key processes are the staggered lamination of positive and negative electrodes and the insertion of a separator between the staggered positive and negative electrodes to isolate them. The incoming electrodes are continuous and uncut. Before lamination, the electrodes need to be cut into individual sheet electrodes. The incoming separator is also a continuous wound strip structure. It needs to be pulled out and covered on the electrode surface before being cut. The traditional single-piece, single-station lamination method has too low lamination efficiency and cannot meet the lamination requirements of high-speed automated production lines. To meet the existing lamination capacity requirements of customers and adapt the lamination efficiency to future development needs, it is necessary to change the existing single-station lamination method. At the same time, it is also necessary to realize the function of laminating multiple electrodes in a single action and coordinate with the electrode picking and cutting and separator pulling and cutting. In addition, during the process of alternating stacking of positive and negative electrodes and insertion of separators, the separator needs to be automatically pressed during the time interval between stacking the next electrode after the separator is completed to prevent the stacked electrodes or separators from shifting or becoming misaligned. In the electrode assembly coating section, the four side walls of the electrode assembly formed after stacking need to be coated and fixed simultaneously. Each side wall of the electrode assembly needs to be coated with multiple strips of adhesive tape at intervals. During the tape coating process, to prevent the electrodes or separators inside the electrode assembly from shifting, the electrode assembly needs to be clamped and fixed by the electrode assembly placement platform. Therefore, the motion interference between the tape coating and the electrode assembly placement platform needs to be resolved during the tape coating process. Simultaneously, to ensure the tape coating effect, the tape coating needs to cover the end walls of the electrode assembly while extending to the upper and lower surfaces of the electrode assembly, maintaining continuous and stable coating pressure during the tape coating process, so that the tape coating action is completed while the electrodes and separators inside the electrode assembly are tightly stacked.

[0019] Beneficial effects of the present invention

[0020] This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing a dual-station alternating stacking feeding system that automatically stacks multiple electrode sheets in a single operation. This system effectively utilizes the station connection time, significantly improves stacking capacity, and features independent side-separated automatic diaphragm pressing. It also enables simultaneous electrode sheet picking, diaphragm pulling, and electrode sheet cutting, simplifying the structure and process, shortening the pre-stacking processing time, and realizing the alternating automatic stacking machine with multi-side wall spacer sealing and pressing functions for electrode groups. This invention is used to realize the production of lithium-ion power batteries, which involves the single-time feeding, cutting, and staggered stacking of four positive and negative electrode sheets, and the pulling out and inserting of the separator to cover between the positive and negative electrode sheets. This invention realizes the alternating operation of feeding and stacking and unloading of stacked sheets. Through the rotation of two platforms, while stacking is carried out on one platform, the other platform sends the stacked electrode assembly to the production line for removal and subsequent hot pressing and coating. This realizes the synchronous operation of each station, reduces waiting time, and improves stacking efficiency. This invention realizes the continuous pressing and coating of multiple side adhesive sheets on one side of the electrode assembly by rotating synchronously.

[0021] Specifically, this invention addresses the effective connection between the stacking and unloading actions after stacking by designing a stacking platform. The stacking platform is designed with stacking stations and unloading stations along a straight line. The stacking platform comprises two stacking supports. One stacking support is supported by a first stacking module and driven to move back and forth in a horizontal straight line. The other stacking support is driven by a second stacking module to move back and forth in the same direction as the first stacking module. Simultaneously, this stacking support is also driven by a third stacking module to move vertically up and down. The actual movement path of this stacking support during operation is a U-shape below the movement plane driven by the first stacking module. The path, or U-shaped path, moves between the stacking station and the stacking unloading station. When the stacking support driven by the first stacking module needs to stack at the stacking station, another stacking support first descends from the stacking station, slides linearly to the stacking station, and then returns linearly to the stacking unloading station before rising to synchronize stacking and unloading. After the stacking support at the stacking station completes stacking, the stacking support at the stacking unloading station descends so that the stacking support at the stacking station returns linearly to the stacking unloading station. Simultaneously, the stacking support at the original stacking unloading station moves linearly to the stacking station before rising to stack. This combination of linearly sliding stacking supports moving along the U-shaped path achieves seamless synchronization between stacking and stacking unloading, reducing waiting time. Furthermore, the lamination support platform of the present invention serves as a lamination support structure. Based on the process requirements during lamination, and considering the lightweight nature of the electrodes and separators, the separator needs to be pressed firmly during the time interval between the first and second electrode stackings after the separator is stacked. Therefore, the lamination support platform has a separator pressing function. The lamination support platform as a whole includes a drive assembly, an electrode support assembly, and a separator pressing assembly. A horizontally arranged lamination support plate serves as the support structure. The electrode support assembly is located in the middle of the lamination support plate. The positive and negative electrodes and the separator are placed alternately on the electrode support assembly. The drive assemblies at both ends of the electrode support assembly drive the separator pressing assembly to press and fix the stacked separator from both sides. The electrode support assembly has an electrode support platform that is slidably supported by an electrode support in the vertical direction and connected to the electrode support by a vertically arranged spring. This vertically elastic structure provides a buffering force during the stacking process, preventing damage caused by excessive pressure when placing the electrode or diaphragm. The electrode support platform of this invention has four electrode placement stations to simultaneously complete the stacking of four electrode groups, improving stacking efficiency. The drive assembly uses a rotating shaft rotatably mounted on the stacking support plate as a power transmission component. The corresponding electrode placement station on the rotating shaft is equipped with four sets of active cams. Each set of active cams includes two active cam plates arranged in parallel and spaced apart. When the rotating shaft rotates, it synchronously drives the four sets of active cams to rotate.The diaphragm pressing assembly of the present invention is disposed between the driving assembly and the electrode support assembly, and the whole assembly includes 8 sets, which are respectively set with four sets of active cams on one side of the electrode support assembly. The diaphragm pressing assembly includes a passive cam, a diaphragm pressing lifting component, a diaphragm pressing translation component and a diaphragm pressing plate. The passive cam is provided with two passive cam plates corresponding to the active cam. One passive cam plate is provided with the diaphragm pressing lifting component and the other passive cam plate is provided with the diaphragm pressing translation component. When the passive cam plate rotates driven by the active cam plate, it transmits power to the diaphragm pressing lifting component and the diaphragm pressing translation component respectively. The diaphragm pressing and lifting component of the present invention uses a lifting lever rotatably mounted on the side wall of the pressing support as a power transmission component. One end of the lifting lever near the passive cam plate is provided with a roller, and the other end is provided with a groove. The upper part of the other end of the lifting lever is provided with a pressing lifting seat that is slidably connected in the vertical direction to the pressing support side wall. The side wall of the pressing lifting seat is provided with a lifting wheel corresponding to the groove. When the lifting lever rotates, the pressing lifting seat is driven to move up and down through the groove and the lifting wheel. In order to avoid motion interference between the lifting motion and the linear translation motion, the pressing lifting seat is provided with a sliding groove in the horizontal direction. The diaphragm translation component of this invention uses a translation lever rotatably connected to the side wall of the diaphragm support as a power transmission component. One end of the translation lever near the passive cam plate has a roller, and the other end has a groove. Above the translation lever is a diaphragm translation seat slidably connected to the side wall of the diaphragm support in a horizontal direction. The lower part of the diaphragm translation seat has a translation roller. When the translation lever rotates, it drives the diaphragm translation seat to move linearly through the groove and the translation roller. A diaphragm seat is slidably connected to the side wall of the diaphragm translation seat, and the diaphragm translation seat drives the translation along the seat, thereby achieving linear drive of the diaphragm seat. Simultaneously, the lower end of the diaphragm seat can also rotate. A pressing roller is connected to the ground. The pressing roller extends into the sliding groove along the pressing lifting seat and moves freely in a straight line within the sliding groove. When the pressing lifting seat is raised or lowered, the pressing roller drives the pressing seat to move up and down. At the same time, when the pressing seat moves horizontally, the pressing roller moves in a straight line within the sliding groove. This linearly slidable structure design with the pressing lifting seat does not cause movement interference with the pressing lifting seat during horizontal movement, effectively realizing the horizontal and vertical movement of the pressing seat. The pressing seat drives the diaphragm pressing plate set on it to move horizontally or vertically, so as to press the diaphragm on the electrode support from above or retract outward to place the diaphragm or electrode.

[0022] To address the process requirements of synchronous stacking of multiple electrode sheets and diaphragm insertion and isolation, this invention innovatively designs a diaphragm-pulling electrode sheet attracting device. This device integrates electrode sheet attracting, electrode sheet cutting, and diaphragm pulling functions. After attracting four electrode sheets from the conveyor belt, the device simultaneously cuts the four connected electrode sheets into single electrode sheets as they move upwards. This allows the four single electrode sheets to be placed on the stacking platform later. Simultaneously, as the electrode sheets are stacked... Then, a diaphragm needs to be covered on the surface. After the electrode is cut by rising, the diaphragm-pulling and electrode-suction device clamps the strip-shaped diaphragm and pulls it straight out from under the electrode. The diaphragm and the electrode move together to the top of the stacking platform. After the diaphragm covers the surface of the stacked electrode on the stacking platform, the electrode descends and is placed on top of the diaphragm, completing one cycle of taking the electrode, cutting the electrode, pulling the diaphragm, covering the diaphragm, and stacking the electrode. The strip-shaped diaphragm is cut by the diaphragm cutting mechanism set on one side of the stacking platform for each individual electrode. The diaphragm-pulling electrode assembly includes a first translation mechanism, a second translation mechanism, a diaphragm-pulling mechanism, and an electrode cutting mechanism. The first linear module of the first translation mechanism is mounted above the stacking platform between the two conveyor belts. The first linear module drives the first slide connected below it to move back and forth in a linear motion. The bottom of the first slide is equipped with four sets of electrode cutting mechanisms. The electrode cutting mechanisms are driven by vertically arranged electrode cylinders to move the suction plates horizontally connected to their lower output ends in a lifting motion. The suction plates adsorb four interconnected electrode sheets from the conveyor belts through vacuum negative pressure. There is also a U-shaped bracket with the opening facing downward between adjacent suction plates. Inside the bottom opening, there are cutting wires along the side of the suction plate. The cutting wires can be tungsten wires. They are connected to an external heating device to generate high temperature. When the suction plate adsorbs the electrode sheets and moves the electrode sheets upward, the interconnected electrode sheets are cut into single electrode sheets by the tungsten wires after passing through the high temperature. The second linear module of the second translation mechanism of the diaphragm-pulling absorber device of the present invention is mounted on the first slide. The second linear module is arranged in the same direction as the first linear module. The output end of the second linear module is connected to the second slide. The second slide extends to the outer side of the end of the second linear module and extends vertically downward to the side of the suction plate. The bottom of the second slide is provided with a strip-shaped clamp extending towards the suction plate. Multiple vertically extending supports are provided parallel to each other on the clamp. Each support is provided with a membrane clamping cylinder with the output end facing downward. The lower part of the output end of the membrane clamping cylinder is provided with a strip-shaped clamping block. The membrane clamping cylinder drives the clamping block to move up and down above the clamp. After the clamping block and the clamp clamp clamp the end of the diaphragm, the second linear module drives the second slide to move the clamp and the clamp as a whole to pull out the diaphragm.

[0023] To address the coating and fixing requirements of stacked electrode assemblies, this invention innovatively designs a coating device to complete the multi-film-interval coating process on all four sides of the electrode assembly. The coating device includes a coating mechanism and a coating platform. The coating mechanism comprises two sets, symmetrically arranged on both sides of the coating platform. The coating platform adopts a rotatable structure design. After the two sets of coating mechanisms complete the coating of the symmetrical sides of the electrode assembly placed on the coating platform in one operation, the coating platform rotates 90°, and the two coating mechanisms complete the coating of the other two sides of the electrode assembly. The coating of all four sides of the electrode assembly is completed through two coating operations. At the same time, for the long side of the electrode assembly, since the required coating area is larger than the single coating area of ​​the coating mechanism, the coating mechanism completes the coating operation by sliding in a straight line along the long side of the electrode assembly. After completing one coating operation, the coating mechanism moves in a straight line to the next position until the coating of all coating positions on the long side of the electrode assembly is completed.

[0024] The coating platform of this invention uses a platform support as a supporting mechanism, on which a platform motor with its output end facing upwards is mounted. A rotating support plate is horizontally connected to the output end of the platform motor as a rotation drive component. An electrode holder is located in the middle of the rotating support plate. The electrode holder includes multiple vertically arranged bearing seats that are parallel to each other. The upper part of the multiple bearing seats forms an electrode assembly placement platform. The gap space between adjacent bearing seats is the coating position, so that the coating assembly can be inserted and pressed tightly to cover the electrode assembly from the side end face and the top and bottom sides. In addition, electrode pressing cylinders are respectively provided at both ends of the electrode holder. The electrode pressing cylinders drive the horizontally arranged electrode pressing blocks to move up and down, so that the electrode pressing blocks press the electrode assembly placed on the electrode holder from above, so as to prevent the position of the stacked electrode or diaphragm from shifting during coating.

[0025] The coating mechanism of the present invention comprises a coating drive assembly, a translation adjustment assembly, a lifting adjustment assembly, a coating assembly, and a glue dispensing assembly. The coating drive assembly uses a support perpendicular to the coating platform as a carrier, and drives a slide block on it to slide linearly via a motor, a lead screw, and a lead screw seat. The linear module of the translation adjustment assembly is arranged on the slide block perpendicular to the support and drives a translation bracket connected to its output end to slide linearly. The glue dispensing assembly and the lifting adjustment assembly comprise two sets, respectively arranged on both sides of the linear module. The glue paper discharged by the glue dispensing assembly is tensioned by the glue dispensing roller and extends vertically upward through the glue guiding gap of the glue guiding support. The lifting adjustment motor of the lifting adjustment assembly drives the lifting adjustment slide block to move the glue pulling cylinder up and down towards the glue guiding support. After the glue paper on the glue guiding support is clamped by the control of the glue clamping claw, the strip of glue paper is torn horizontally along the plane where the glue guiding gap is located.

[0026] The coating assembly of this invention comprises two sets, simultaneously disposed on both sides of a linear module. The two sets of coating assemblies simultaneously adsorb two pieces of adhesive paper from the adhesive dispensing assembly vertically and then coat them onto the electrode side. The coating assembly uses a vertically arranged coating support plate as its supporting structure. The coating support plate is mounted on a translational bracket and moves linearly with the translational bracket in both longitudinal and transverse directions. A coating support seat is horizontally arranged on the coating support plate, and a coating cylinder is mounted on the coating support seat. A vertically arranged coating pusher seat is also fitted onto the coating support seat. The coating pusher seat is slidably connected to the coating support seat and connected to the output end of the coating cylinder. A stop plate is horizontally connected to the bottom of the coating pusher seat. The stop plate extends from one side to the other through the coating support plate. The outer end face of the stop plate is planar. During the coating process, the stop plate continuously holds the adhesive paper against the electrode assembly end face. Two sets of coating components are symmetrically arranged on the upper and lower sides of the backing plate. The coating components use a coating suction plate horizontally set on the side wall of the coating support plate as a carrier. A gap is left between the coating suction plate and the backing plate. A coating suction seat is provided on the outside of the coating suction plate, and a coating suction nozzle is provided on the coating suction seat. By forming a vacuum negative pressure on the outer surface of the coating suction seat through the coating suction nozzle, the adhesive paper to be coated is sucked and fixed from the clamping claw of the adhesive dispensing component. A coating roller plate is provided between the coating suction plate and the backing plate. One end of the coating roller plate is rotatably connected to the side wall of the coating support plate, and the other end of the coating roller plate is rotatably connected to the coating roller. When the backing plate presses the vertically adsorbed adhesive paper against the end wall of the electrode assembly, the coating roller plate is positioned above and below the backing plate. The coating rollers on both sides press against the adhesive paper from the top and bottom. As the coating support plate moves synchronously towards the electrode assembly, the coating rollers gradually slide the adhesive paper to the top and bottom sides of the electrode assembly. The adhesive-pressing cylinder, located outside the coating suction plate, drives the adhesive-pressing ball to output continuous power, pressing the coating rollers towards the side wall of the electrode assembly. This causes the coating rollers to press the adhesive paper onto the surface of the electrode assembly while sliding along the top and bottom surfaces of the electrode assembly. Simultaneously, the coating cylinder drives the push plate to retract away from the electrode assembly, maintaining a synchronous movement opposite to that of the coating support plate. This keeps the adhesive paper pressed against the side wall of the electrode assembly until the coating rollers complete the coating process. Attached Figure Description

[0067] Furthermore, this invention designs a dual-station alternating stacking feeding system that automatically stacks multiple electrode sheets in a single operation. This effectively utilizes the station connection time, significantly improving stacking capacity. It features independent side-by-side automatic separator pressing, simultaneous electrode sheet picking, separator pulling, and electrode sheet cutting, simplifying the structure and process, shortening pre-stacking processing time, and realizing an alternating automatic stacking machine with multi-sidewall spacer bonding and adhesive application for electrode groups. This invention is used to realize the single-stage picking, cutting, and staggered stacking of four positive and negative electrode sheets for lithium-ion power batteries, and the separation of the separator being pulled out and inserted between the positive and negative electrode sheets. This invention achieves alternating operation of loading and stacking, with dual-platform rotation. While stacking is performed on one platform, the other platform delivers the stacked electrode group to the production line for removal and subsequent hot-pressing and adhesive application, achieving synchronous operation at each station, reducing waiting time, and improving stacking efficiency. This invention also enables the continuous pressing and coating of multiple side-adhesive sheets on one side of the electrode group during synchronous rotation.

[0068] Specifically, this invention addresses the effective connection between the stacking and unloading actions after stacking by designing a stacking platform. The stacking platform is designed with stacking stations and unloading stations along a straight line. The stacking platform comprises two stacking supports. One stacking support is supported by a first stacking module and driven to move back and forth in a horizontal straight line. The other stacking support is driven by a second stacking module to move back and forth in the same direction as the first stacking module. Simultaneously, this stacking support is also driven by a third stacking module to move vertically up and down. The actual movement path of this stacking support during operation is a U-shape below the movement plane driven by the first stacking module. The path, or U-shaped path, moves between the stacking station and the stacking unloading station. When the stacking support driven by the first stacking module needs to stack at the stacking station, another stacking support first descends from the stacking station, slides linearly to the stacking station, and then returns linearly to the stacking unloading station before rising to synchronize stacking and unloading. After the stacking support at the stacking station completes stacking, the stacking support at the stacking unloading station descends so that the stacking support at the stacking station returns linearly to the stacking unloading station. Simultaneously, the stacking support at the original stacking unloading station moves linearly to the stacking station before rising to stack. This combination of linearly sliding stacking supports moving along the U-shaped path achieves seamless synchronization between stacking and stacking unloading, reducing waiting time. Furthermore, the lamination support platform of the present invention serves as a lamination support structure. Based on the process requirements during lamination, and considering the lightweight nature of the electrodes and separators, the separator needs to be pressed firmly during the time interval between the first and second electrode stackings after the separator is stacked. Therefore, the lamination support platform has a separator pressing function. The lamination support platform as a whole includes a drive assembly, an electrode support assembly, and a separator pressing assembly. A horizontally arranged lamination support plate serves as the support structure. The electrode support assembly is located in the middle of the lamination support plate. The positive and negative electrodes and the separator are placed alternately on the electrode support assembly. The drive assemblies at both ends of the electrode support assembly drive the separator pressing assembly to press and fix the stacked separator from both sides. The electrode support assembly has an electrode support platform that is slidably supported by an electrode support in the vertical direction and connected to the electrode support by a vertically arranged spring. This vertically elastic structure provides a buffering force during the stacking process, preventing damage caused by excessive pressure when placing the electrode or diaphragm. The electrode support platform of this invention has four electrode placement stations to simultaneously complete the stacking of four electrode groups, improving stacking efficiency. The drive assembly uses a rotating shaft rotatably mounted on the stacking support plate as a power transmission component. The corresponding electrode placement station on the rotating shaft is equipped with four sets of active cams. Each set of active cams includes two active cam plates arranged in parallel and spaced apart. When the rotating shaft rotates, it synchronously drives the four sets of active cams to rotate.The diaphragm pressing assembly of the present invention is disposed between the driving assembly and the electrode support assembly, and the whole assembly includes 8 sets, which are respectively set with four sets of active cams on one side of the electrode support assembly. The diaphragm pressing assembly includes a passive cam, a diaphragm pressing lifting component, a diaphragm pressing translation component and a diaphragm pressing plate. The passive cam is provided with two passive cam plates corresponding to the active cam. One passive cam plate is provided with the diaphragm pressing lifting component and the other passive cam plate is provided with the diaphragm pressing translation component. When the passive cam plate rotates driven by the active cam plate, it transmits power to the diaphragm pressing lifting component and the diaphragm pressing translation component respectively. The diaphragm pressing and lifting component of the present invention uses a lifting lever rotatably mounted on the side wall of the pressing support as a power transmission component. One end of the lifting lever near the passive cam plate is provided with a roller, and the other end is provided with a groove. The upper part of the other end of the lifting lever is provided with a pressing lifting seat that is slidably connected in the vertical direction to the pressing support side wall. The side wall of the pressing lifting seat is provided with a lifting wheel corresponding to the groove. When the lifting lever rotates, the pressing lifting seat is driven to move up and down through the groove and the lifting wheel. In order to avoid motion interference between the lifting motion and the linear translation motion, the pressing lifting seat is provided with a sliding groove in the horizontal direction. The diaphragm translation component of this invention uses a translation lever rotatably connected to the side wall of the diaphragm support as a power transmission component. One end of the translation lever near the passive cam plate has a roller, and the other end has a groove. Above the translation lever is a diaphragm translation seat slidably connected to the side wall of the diaphragm support in a horizontal direction. The lower part of the diaphragm translation seat has a translation roller. When the translation lever rotates, it drives the diaphragm translation seat to move linearly through the groove and the translation roller. A diaphragm seat is slidably connected to the side wall of the diaphragm translation seat, and the diaphragm translation seat drives the translation along the seat, thereby achieving linear drive of the diaphragm seat. Simultaneously, the lower end of the diaphragm seat can also rotate. A pressing roller is connected to the ground. The pressing roller extends into the sliding groove along the pressing lifting seat and moves freely in a straight line within the sliding groove. When the pressing lifting seat is raised or lowered, the pressing roller drives the pressing seat to move up and down. At the same time, when the pressing seat moves horizontally, the pressing roller moves in a straight line within the sliding groove. This linearly slidable structure design with the pressing lifting seat does not cause movement interference with the pressing lifting seat during horizontal movement, effectively realizing the horizontal and vertical movement of the pressing seat. The pressing seat drives the diaphragm pressing plate set on it to move horizontally or vertically, so as to press the diaphragm on the electrode support from above or retract outward to place the diaphragm or electrode.

[0069] To address the process requirements of synchronous stacking of multiple electrode sheets and diaphragm insertion and isolation, this invention innovatively designs a diaphragm-pulling electrode sheet attracting device. This device integrates electrode sheet attracting, electrode sheet cutting, and diaphragm pulling functions. After attracting four electrode sheets from the conveyor belt, the device simultaneously cuts the four connected electrode sheets into single electrode sheets as they move upwards. This allows the four single electrode sheets to be placed on the stacking platform later. Simultaneously, as the electrode sheets are stacked... Then, a diaphragm needs to be covered on the surface. After the electrode is cut by rising, the diaphragm-pulling and electrode-suction device clamps the strip-shaped diaphragm and pulls it straight out from under the electrode. The diaphragm and the electrode move together to the top of the stacking platform. After the diaphragm covers the surface of the stacked electrode on the stacking platform, the electrode descends and is placed on top of the diaphragm, completing one cycle of taking the electrode, cutting the electrode, pulling the diaphragm, covering the diaphragm, and stacking the electrode. The strip-shaped diaphragm is cut by the diaphragm cutting mechanism set on one side of the stacking platform for each individual electrode. The diaphragm-pulling electrode assembly includes a first translation mechanism, a second translation mechanism, a diaphragm-pulling mechanism, and an electrode cutting mechanism. The first linear module of the first translation mechanism is mounted above the stacking platform between the two conveyor belts. The first linear module drives the first slide connected below it to move back and forth in a linear motion. The bottom of the first slide is equipped with four sets of electrode cutting mechanisms. The electrode cutting mechanisms are driven by vertically arranged electrode cylinders to move the suction plates horizontally connected to their lower output ends in a lifting motion. The suction plates adsorb four interconnected electrode sheets from the conveyor belts through vacuum negative pressure. There is also a U-shaped bracket with the opening facing downward between adjacent suction plates. Inside the bottom opening, there are cutting wires along the side of the suction plate. The cutting wires can be tungsten wires. They are connected to an external heating device to generate high temperature. When the suction plate adsorbs the electrode sheets and moves the electrode sheets upward, the interconnected electrode sheets are cut into single electrode sheets by the tungsten wires after passing through the high temperature. The second linear module of the second translation mechanism of the diaphragm-pulling absorber device of the present invention is mounted on the first slide. The second linear module is arranged in the same direction as the first linear module. The output end of the second linear module is connected to the second slide. The second slide extends to the outer side of the end of the second linear module and extends vertically downward to the side of the suction plate. The bottom of the second slide is provided with a strip-shaped clamp extending towards the suction plate. Multiple vertically extending supports are provided parallel to each other on the clamp. Each support is provided with a membrane clamping cylinder with the output end facing downward. The lower part of the output end of the membrane clamping cylinder is provided with a strip-shaped clamping block. The membrane clamping cylinder drives the clamping block to move up and down above the clamp. After the clamping block and the clamp clamp clamp the end of the diaphragm, the second linear module drives the second slide to move the clamp and the clamp as a whole to pull out the diaphragm.

[0070] To address the coating and fixing requirements of stacked electrode assemblies, this invention innovatively designs a coating device to complete the multi-film-interval coating process on all four sides of the electrode assembly. The coating device includes a coating mechanism and a coating platform. The coating mechanism comprises two sets, symmetrically arranged on both sides of the coating platform. The coating platform adopts a rotatable structure design. After the two sets of coating mechanisms complete the coating of the symmetrical sides of the electrode assembly placed on the coating platform in one operation, the coating platform rotates 90°, and the two coating mechanisms complete the coating of the other two sides of the electrode assembly. The coating of all four sides of the electrode assembly is completed through two coating operations. At the same time, for the long side of the electrode assembly, since the required coating area is larger than the single coating area of ​​the coating mechanism, the coating mechanism completes the coating operation by sliding in a straight line along the long side of the electrode assembly. After completing one coating operation, the coating mechanism moves in a straight line to the next position until the coating of all coating positions on the long side of the electrode assembly is completed.

[0071] The coating platform of this invention uses a platform support as a supporting mechanism, on which a platform motor with its output end facing upwards is mounted. A rotating support plate is horizontally connected to the output end of the platform motor as a rotation drive component. An electrode holder is located in the middle of the rotating support plate. The electrode holder includes multiple vertically arranged bearing seats that are parallel to each other. The upper part of the multiple bearing seats forms an electrode assembly placement platform. The gap space between adjacent bearing seats is the coating position, so that the coating assembly can be inserted and pressed tightly to cover the electrode assembly from the side end face and the top and bottom sides. In addition, electrode pressing cylinders are respectively provided at both ends of the electrode holder. The electrode pressing cylinders drive the horizontally arranged electrode pressing blocks to move up and down, so that the electrode pressing blocks press the electrode assembly placed on the electrode holder from above, so as to prevent the position of the stacked electrode or diaphragm from shifting during coating.

[0072] The coating mechanism of the present invention comprises a coating drive assembly, a translation adjustment assembly, a lifting adjustment assembly, a coating assembly, and a glue dispensing assembly. The coating drive assembly uses a support perpendicular to the coating platform as a carrier, and drives a slide block on it to slide linearly via a motor, a lead screw, and a lead screw seat. The linear module of the translation adjustment assembly is arranged on the slide block perpendicular to the support and drives a translation bracket connected to its output end to slide linearly. The glue dispensing assembly and the lifting adjustment assembly comprise two sets, respectively arranged on both sides of the linear module. The glue paper discharged by the glue dispensing assembly is tensioned by the glue dispensing roller and extends vertically upward through the glue guiding gap of the glue guiding support. The lifting adjustment motor of the lifting adjustment assembly drives the lifting adjustment slide block to move the glue pulling cylinder up and down towards the glue guiding support. After the glue paper on the glue guiding support is clamped by the control of the glue clamping claw, the strip of glue paper is torn horizontally along the plane where the glue guiding gap is located.

[0073] The coating assembly of this invention comprises two sets, simultaneously disposed on both sides of a linear module. The two sets of coating assemblies simultaneously adsorb two pieces of adhesive paper from the adhesive dispensing assembly vertically and then coat them onto the electrode side. The coating assembly uses a vertically arranged coating support plate as its supporting structure. The coating support plate is mounted on a translational bracket and moves linearly with the translational bracket in both longitudinal and transverse directions. A coating support seat is horizontally arranged on the coating support plate, and a coating cylinder is mounted on the coating support seat. A vertically arranged coating pusher seat is also fitted onto the coating support seat. The coating pusher seat is slidably connected to the coating support seat and connected to the output end of the coating cylinder. A stop plate is horizontally connected to the bottom of the coating pusher seat. The stop plate extends from one side to the other through the coating support plate. The outer end face of the stop plate is planar. During the coating process, the stop plate continuously holds the adhesive paper against the electrode assembly end face. Two sets of coating components are symmetrically arranged on the upper and lower sides of the backing plate. The coating components use a coating suction plate horizontally set on the side wall of the coating support plate as a carrier. A gap is left between the coating suction plate and the backing plate. A coating suction seat is provided on the outside of the coating suction plate, and a coating suction nozzle is provided on the coating suction seat. By forming a vacuum negative pressure on the outer surface of the coating suction seat through the coating suction nozzle, the adhesive paper to be coated is sucked and fixed from the clamping claw of the adhesive dispensing component. A coating roller plate is provided between the coating suction plate and the backing plate. One end of the coating roller plate is rotatably connected to the side wall of the coating support plate, and the other end of the coating roller plate is rotatably connected to the coating roller. When the backing plate presses the vertically adsorbed adhesive paper against the end wall of the electrode assembly, the coating roller plate is positioned above and below the backing plate. The coating rollers on both sides press against the adhesive paper from the top and bottom. As the coating support plate moves synchronously towards the electrode assembly, the coating rollers gradually slide the adhesive paper to the top and bottom sides of the electrode assembly. The adhesive-pressing cylinder, located outside the coating suction plate, drives the adhesive-pressing ball to output continuous power, pressing the coating rollers towards the side wall of the electrode assembly. This causes the coating rollers to press the adhesive paper onto the surface of the electrode assembly while sliding along the top and bottom surfaces of the electrode assembly. Simultaneously, the coating cylinder drives the push plate to retract away from the electrode assembly, maintaining a synchronous movement opposite to that of the coating support plate. This keeps the adhesive paper pressed against the side wall of the electrode assembly until the coating rollers complete the coating process.
