Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery manufacturing equipment technology, and in particular to a high-speed adhesive application device and method for pre-peeling the upper release paper. Background Technology

[0002] In the assembly of power battery modules for new energy vehicles, adhesive films need to be pasted onto the surface of the battery cells to achieve functions such as insulation, fixation, or heat dissipation. These films are usually double-sided adhesives with two layers of release paper. Existing automated adhesive application equipment typically integrates the upper release paper removal process into an adhesive application gripper or a separate upper release paper removal mechanism. For example, as shown in patent publication number CN120376716A, a first robotic arm removes the lower release paper and applies adhesive. After adhesive application, the battery cell is transferred to a second station where a second robotic arm removes the upper release paper. As shown in patent publication number CN217405497U, separate mechanisms for removing the lower and upper release papers are set up. After the adhesive film is applied and rolled, the upper release paper is removed by a separate mechanism. These existing adhesive applicators all remove the release paper after applying the adhesive. In scenarios involving multi-station collaborative operation and switching between different battery pack quantities, this method can easily lead to limited adhesive application cycle time, affecting the overall line efficiency. Furthermore, a separate actuator is required for removing the release paper, increasing equipment costs and floor space. The adhesive applicator gripper needs to coordinate with the subsequent release paper removal mechanism, resulting in complex control logic and severely limiting the adhesive application cycle time.

[0003] As the assembly of new energy vehicle batteries moves towards multi-specification parallel production and high cycle time, adhesive application equipment has higher requirements for process flexibility and cycle time efficiency. There is an urgent need for adhesive application equipment and process methods that can significantly improve adhesive application cycle time and process compatibility, and simplify equipment structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a high-speed adhesive application device and method with pre-tear-off upper release paper. By decoupling the adhesive application process and reconstructing the adhesive application mechanism and process flow, the upper release paper tear-off process is moved forward and integrated with the material picking action, thereby significantly improving the adhesive application cycle time. This effectively solves the technical problems of slow adhesive application cycle time and large equipment footprint of existing adhesive application machines.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] One technical solution of the present invention provides a high-speed adhesive applicator for pre-tear-off of upper release paper, including a hopper, a material handling gripper, a lower release paper tearing mechanism, a centering shuttle table, and an adhesive applicator.

[0007] The hopper is used to store film with upper and lower release papers;

[0008] The material handling gripper is used to transfer film between the hopper, the release paper tearing mechanism, and the centering shuttle table;

[0009] The material handling gripper is integrated with an upper release paper clamp, which is used to clamp the upper release paper of the film during material handling;

[0010] The lower release paper tearing mechanism is used to tear off the lower release paper of the film;

[0011] The centering shuttle is used to receive and position the film.

[0012] The centering shuttle platform is equipped with a vacuum adsorption device for adsorbing and fixing the film, which is used in conjunction with the release paper claws to tear off the release paper when they retract.

[0013] The adhesive gripper is used to obtain adhesive film from the centering shuttle table and apply it to the surface of the battery cell.

[0014] Using the above technical solution, the working process of the high-speed adhesive applicator of the present invention is configured as follows:

[0015] The material handling gripper retrieves the film with upper and lower release papers from the hopper. At the same time, the upper release paper gripper holds the upper release paper of the film. The material handling gripper transfers the film to the lower release paper tearing mechanism to tear off the lower release paper of the film. Then, the material handling gripper transfers the film to the centering shuttle table for positioning. The film is then adsorbed and fixed by the vacuum adsorption device. The material handling gripper then retracts and the upper release paper gripper tears the upper release paper off the film. The adhesive application gripper retrieves the film with the upper and lower release papers removed from the centering shuttle table and applies it to the surface of the battery cell.

[0016] In some possible implementations, the material handling gripper includes a multi-axis robotic arm, the execution end of which is vertically connected to a mounting frame. On one side of the mounting frame, multiple sets of parallel suction cup assemblies are vertically arranged, and on the other side of the mounting frame, multiple sets of upper release paper grippers are vertically arranged. Each set of suction cup assemblies cooperates with a set of upper release paper grippers to pick up the film while holding the upper release paper of the film.

[0017] The upper release paper clamping claw includes a linear drive mechanism, a fixed claw, and a movable claw. The linear drive mechanism is vertically fixedly connected to the mounting frame. The fixed claw is vertically disposed on the side of the suction cup assembly and fixedly connected to the mounting frame. The movable claw is fixed below the output end of the linear drive mechanism. The linear drive mechanism drives the movable claw to move up and down to cooperate with the fixed claw to clamp the upper release paper.

[0018] Using the above technical solution, the multi-axis robotic arm rotates to move multiple sets of suction cup assemblies on the mounting frame to the material bin for material retrieval. Each set of suction cup assemblies picks up a film with upper and lower release papers. At the same time, the linear drive mechanism drives the movable claw downward to move it down so that the upper release paper clamping claw opens. The lower part of the movable claw moves to below the tear tab in the upper release paper. Then, the linear drive mechanism drives the movable claw upward. At this time, the movable claw lifts the tear tab of the upper release paper. When the upper release paper clamping claw closes, the tear tab is clamped between the movable claw and the fixed claw.

[0019] Because the release force of the adhesive sheet used for bonding power batteries is relatively small, and the strength of the upper release paper tear tab structure is limited, improper control of the relative position between the upper release paper clamps and the adhesive sheet can easily lead to premature peeling or tearing of the tear tabs during clamping, thus affecting the tearing stability. Therefore, this invention incorporates process constraint design for the clamping height of the upper release paper clamps.

[0020] In some possible implementations, when the upper release paper grippers close, the initial distance H from the bottom surface of the movable gripper to the surface of the upper release paper, and the effective length S of the upper release paper tear, satisfy the following relationship: H=K·S, where K is a correction coefficient, and K takes a value of 0.3~0.4, so as to avoid the tear being peeled off prematurely due to the gripping position being too high.

[0021] In some possible implementations, the suction cup assembly is an accordion suction cup with a free height of L, an effective length of S for the upper release paper tear, and an initial distance H from the bottom surface of the movable claw to the surface of the upper release paper satisfying the relationship: H=K·S+L / 2, where K is a correction coefficient with a value of 0.3~0.4, thereby achieving stable clamping of the upper release paper tear and smoothly completing the overall peeling of the upper release paper after the film is adsorbed on the center shuttle table, thus ensuring the reliability of the tearing process.

[0022] Furthermore, the suction cup assembly is fixedly connected to the mounting frame via several detachably fixed suction cup brackets. Each suction cup bracket has a strip-shaped adjustment hole, and the suction cup assembly is detachably vertically inserted into the adjustment hole. By changing the installation and connection position of the suction cup assembly and the adjustment hole, the distance between the suction cup assembly and the upper release paper clamp can be adjusted, which can match different models and sizes of films, accurately pick up the films, and further ensure that the upper release paper clamp stably grips the film tear ears.

[0023] In some possible implementations, the lower release paper tearing mechanism includes a flipping cylinder, a flipping shaft fixedly connected to the output end of the flipping cylinder, and a plurality of paper tearing gripper assemblies distributed along the axial direction of the flipping shaft.

[0024] The paper tearing gripper assembly includes a vertically arranged upper fixed gripper, a lower movable gripper, and a lower gripper linear drive. The upper fixed gripper includes a connecting part and a clamping part. The connecting part is vertically connected to the flipping shaft and rotates synchronously. The clamping part is horizontally fixed to the top of the connecting part. The lower movable gripper is located below the clamping part. The lower gripper linear drive is vertically arranged and fixedly connected to the side of the connecting part. The movable end at the top of the lower gripper linear drive is fixedly connected to the lower movable gripper.

[0025] During operation, the material handling gripper picks up the film with upper and lower release papers and moves it to the lower release paper tearing mechanism to peel off the lower release paper: the lower jaw linear drive drives the lower movable jaw to move upward, the lower movable jaw and the upper fixed jaw clamping part close together and clamp the tearing ear part of the lower release paper, and the flipping cylinder drives the flipping shaft to drive the tearing jaw assembly to rotate synchronously. Preferably, the flipping shaft rotates on the side where the clamping part is located to separate the lower release paper from the film.

[0026] Furthermore, several locking blocks are fixedly mounted on the flip shaft. The locking blocks are connected to and fixed to the flip shaft through "C"-shaped slots. The connecting part of the upper fixed gripper is connected to the locking blocks to achieve synchronous rotation with the flip shaft.

[0027] In some possible implementations, a recycling bin for recycling the release paper is provided below the paper tearing gripper assembly, an air pipe connector is connected to the side of the connecting part, the air pipe connector is connected to an external air blowing device, an air blowing hole is provided on the upper end of the connecting part near the lower movable gripper, and an air flow channel is provided inside the connecting part, with the two ends of the air flow channel connected to the air pipe connector and the air blowing hole respectively.

[0028] After the paper-tearing gripper assembly tears off the lower release paper, the material handling gripper transfers the film stripped from the lower release paper to the centering shuttle table. At this time, the lower gripper linear drive drives the lower movable gripper to move downward, and the lower movable gripper opens up between itself and the clamping part. Simultaneously, the external air blowing device blows air out through the air pipe joint, airflow channel and air blowing hole in sequence to help blow the lower release paper down to the recycling bin below for recycling, so as to avoid sticking to the lower movable gripper or the clamping part.

[0029] Furthermore, a photoelectric detection switch is connected to the connecting part, and a sensing block is connected to the side of the lower movable gripper. The sensing block corresponds to the position of the photoelectric detection switch. The photoelectric detection switch replaces the traditional magnetic switch, improving the stability of monitoring performance. The photoelectric detection switch can sense and monitor the movement position of the lower movable gripper in real time through the position of the sensing block, thereby accurately and stably controlling the lower movable gripper to close and clamp the lower release paper with the upper fixed gripper. In addition, the photoelectric detection switch can also be configured to sense the height of the material level in the lower recycling bin, thereby monitoring the storage height of the lower release paper in the recycling bin in real time and transferring it in time when the bin is full.

[0030] In some possible implementations, the centering shuttle includes two sets of parallel servo linear modules. Each set of servo linear modules is connected to a centering mechanism. The two sets of centering mechanisms have different horizontal heights at their bottoms. The centering mechanism is used to uniformly position multiple sets of films at one time. The two sets of servo linear modules drive the centering mechanism on them to reciprocate along their axial direction. Because the two sets of centering mechanisms have different horizontal heights of displacement, they can shuttle back and forth on different height planes, continuously receiving and fixing the films put in by the material picker, and continuously supplying materials to the adhesive gripper, thus ensuring the stability of the high-speed production line's cycle time.

[0031] Each centering mechanism is equipped with a positioning platform, and multiple glue carriers are arranged in parallel and spaced apart on the positioning platform. The glue carriers are provided with negative pressure channels inside.

[0032] The vacuum adsorption device includes a vacuum generator and a suction cup. The suction cup is vertically inserted inside the adhesive carrier stage. The lower port of the suction cup is connected to the negative pressure channel. The vacuum generator is connected to the negative pressure channel through a pipeline. The upper port of the suction cup is located on the upper surface of the adhesive carrier stage and is used to adsorb the film.

[0033] During operation, after the lower release paper tearing mechanism tears off the lower release paper, the material grabber transports the film with the upper release paper to the adhesive table. The vacuum generator is activated, and the film is adsorbed and fixed to the adhesive table by the suction cup. Then the material grabber moves up and retracts, while the upper release paper gripper peels the upper release paper off the surface of the film.

[0034] In some possible implementations, the centering mechanism is further provided with a first positioning mechanism and a second positioning mechanism, the positioning platform is provided with a first slide rail and a second slide rail with perpendicular directions, and a first limiting plate and a second limiting plate are fixed on two adjacent sides of the glue carrier.

[0035] The first positioning mechanism includes a first driving device, a first driving plate connected to the output shaft of the first driving device, a first sliding plate fixedly connected to the first driving plate, and a plurality of first push blocks fixed on the first sliding plate. The first driving device is located below the positioning platform, the first driving plate is vertically located on the side of the positioning platform, the first sliding plate is parallel to and slidably connected to the first slide rail, the first push block is located on the side of the glue carrier and perpendicular to the first sliding plate, the side of the first push block is connected to a first push plate, and the first push plate and the first limiting plate are located on both sides of the glue carrier respectively.

[0036] The second positioning mechanism includes a second driving device located below the positioning platform. The output shaft of the second driving device is connected to at least two lead screw drive shafts via a synchronous belt. A second driving plate is meshed on the lead screw drive shaft. The second driving plate is vertically arranged and a second sliding plate is fixedly connected to its upper end. The second sliding plate is parallel to and slidably connected to the second slide rail. Several second push blocks are fixed to the side of the second sliding plate. A second push plate is connected to the side of the second push block near the glue carrier table. The second push plate is perpendicular to the first push plate. The second push plate and the second limiting plate are located on both sides of the glue carrier table.

[0037] After the release liner gripper peels the release liner from the film surface, the vacuum generator releases the vacuum, the suction cup releases the film, and the positions of multiple sets of films can be uniformly adjusted on the adhesive table through the first and second positioning mechanisms. This facilitates the adhesive applicator to pick up the film and apply it, ensuring the accuracy and consistency of the adhesive application position. The first positioning mechanism drives the first drive plate to perform synchronous linear telescopic movement through the first drive device, and drives the first sliding plate to slide linearly along the first slide rail. This further drives the first push block and the first push plate to push the film against the first limiting plate from the side, so that the film is positioned in the X-axis direction (refer to...). Figure 11 The upper limit (as indicated by the symbol) is located between the first push plate and the first limiting plate; the second positioning mechanism rotates through the second drive device, which drives the lead screw drive shaft to rotate synchronously through the synchronous belt. The second drive plate reciprocates along the axial direction of the lead screw drive shaft, thereby driving the second push block and the second push plate to push the film against the second limiting plate from the other side of the film, so that the film moves in the Y-axis direction (refer to the reference). Figure 11 The upper limit (as indicated by the label) is located between the second push plate and the second limit plate, thereby achieving the centering adjustment of the film position.

[0038] Furthermore, the adhesive applicator includes a spider-hand robot and an adhesive applicator mechanism connected below the spider-hand robot. The adhesive applicator mechanism includes a drive motor and a multi-suction cup mechanism that rotates synchronously with the motor shaft of the drive motor. The spider-hand robot drives the adhesive applicator mechanism to pick up the adhesive sheet from above the adhesive platform through the multi-suction cup mechanism, and then drives the multi-suction cup mechanism to rotate 90 degrees through the drive motor, thus attaching the adhesive sheet to the vertical surface of the battery cell at the adhesive applicator station.

[0039] Furthermore, the high-speed adhesive applicator is also equipped with a visual inspection device, which is located between the lower release paper tearing mechanism and the centering shuttle table, and can also be located on the material handling gripper, to detect whether the lower and upper release papers of the film have been completely torn off.

[0040] This invention also provides a high-speed adhesive application method for pre-peeling the upper release paper, using the high-speed adhesive application device described in any of the above technical solutions, and performing the following steps:

[0041] S1: Pick up and clamp the upper release paper: The picking gripper picks up the film with upper and lower release papers from the hopper and clamps the upper release paper of the film with the upper release paper clamp integrated on it.

[0042] S2: Lower release paper tearing: The material handling gripper transfers the film to the lower release paper tearing mechanism to tear off the lower release paper;

[0043] S3: Top release paper tearing: The material grabber transfers the film with the top release paper and places it on the centering shuttle table. The vacuum adsorption device is activated to adsorb and fix the film. Then, when the material grabber retracts, the top release paper is torn off from the adsorbed and fixed film through the top release paper gripper.

[0044] S4: Film Position Alignment: Turn off the vacuum adsorption device and adjust the position of the film, from which both the upper and lower release papers have been removed, using the alignment shuttle table;

[0045] S5: Cell Adhesive Application: The adhesive application gripper picks up the adhesive film from the centering shuttle table and applies it to the surface of the cell.

[0046] In some possible implementations, after step S2, the film is inspected by a visual inspection device to confirm that the lower release paper has been completely removed; after step S3, the film is inspected by a visual inspection device to confirm that the upper release paper has been completely removed.

[0047] Compared with the prior art, the present invention has the following advantages:

[0048] The high-speed adhesive application device with pre-tear-off upper release paper provided by this invention integrates an upper release paper gripper on the material handling gripper. During the material handling stage, the upper release paper's tear tab is clamped. Subsequently, the adhesive sheet is fixed using vacuum adsorption on the centering shuttle table, and the upper release paper is directly torn off by retracting the material handling gripper. This achieves pre-clamping and coordinated tearing of the upper release paper, reducing the steps and time required for separate upper release paper handling in traditional processes, and significantly improving the overall adhesive application efficiency. This invention integrates multiple functions such as material handling, tearing off the lower release paper, positioning, tearing off the upper release paper, and adhesive application into a single high-speed adhesive application device, achieving high integration and automated operation. Through the coordinated operation of various mechanisms, the entire process from material supply to adhesive application is automated, reducing manual intervention, improving production efficiency and process consistency, and is suitable for high-volume, high-cycle adhesive application scenarios such as power batteries.

[0070] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention will be presented in conjunction with preferred embodiments, this does not mean that the features of the invention are limited to these embodiments. To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0071] refer to Figure 1 and Figure 2One embodiment of the present invention provides a high-speed adhesive applicator for pre-tear-off of upper release paper, including a hopper 1, a material handling gripper 2, a lower release paper tearing mechanism 3, a centering shuttle table 4, and an adhesive applicator 5. The hopper 1 is used to store film 100 with upper and lower release papers. The material handling gripper 2 is used to transfer the film 100 between the material bin 1, the lower release paper tearing mechanism 3, and the centering shuttle table 4. The material handling gripper 2 is integrated with an upper release paper gripper 6, which is used to hold the upper release paper 101 attached to the adhesive surface of the film 100 during material handling. The lower release paper tearing mechanism 3 is used to tear off the lower release paper 102 attached to the lower adhesive surface of the film 100. The centering shuttle table 4 is used to receive and position the film 100. The centering shuttle table 4 is equipped with a vacuum adsorption device 41, which is used to adsorb and fix the film 100, and tear off the upper release paper 101 when the upper release paper gripper 6 retracts. The adhesive application gripper 5 is used to obtain the film 100 from the centering shuttle table 4 and apply it to the surface of the battery cell.

[0072] The working process of the above-mentioned high-speed adhesive applicator is configured as follows:

[0073] The material handling gripper 2 picks up the film 100 with upper and lower release papers from the hopper 1. At the same time, the upper release paper gripper 6 holds the upper release paper 101 of the film 100. The material handling gripper 2 transfers the film 100 to the lower release paper tearing mechanism 3 to tear off the lower release paper 102 of the film 100. Then, the material handling gripper 2 transfers the film 100 to the centering shuttle table 4 for positioning. The vacuum adsorption device 41 adsorbs and fixes the film 100. The material handling gripper 2 then retracts and the upper release paper 101 is torn off the film 100 by the upper release paper gripper 6. The adhesive application gripper 5 picks up the film 100 with the upper and lower release papers removed from the centering shuttle table 4 and attaches it to the surface of the battery cell.

[0074] In this embodiment, the upper release paper clamp 6 and the lower release paper tearing mechanism 3 are respectively clamped at the tearing ears of the upper and lower release papers.

[0075] The silo in this embodiment includes at least two silos, which can be arranged in a one-for-one configuration to ensure uninterrupted material feeding and a high-efficiency production cycle.

[0076] refer to Figure 3 and Figure 4 The material handling gripper 2 includes a multi-axis robotic arm 21. The execution end of the multi-axis robotic arm 21 is vertically connected to a mounting frame 22. On one side of the mounting frame 22, multiple sets of parallel suction cup assemblies 23 are vertically arranged. The suction cup assemblies 23 are connected to an external vacuum device through pipes to create negative pressure to pick up the film 100 with upper and lower release papers. On the other side of the mounting frame 22, multiple sets of upper release paper grippers 6 are vertically arranged. Each set of suction cup assemblies 23 cooperates with a set of upper release paper grippers 6 to pick up the film 100 while holding the upper release paper 101 of the film 100.

[0077] refer to Figures 4 to 6 The upper release paper gripper 6 includes a linear drive mechanism 61, a fixed gripper 62, and a movable gripper 63. The linear drive mechanism 61 is vertically fixedly connected to the mounting frame 22, and the linear drive mechanism 61 and the suction cup assembly 23 are located on opposite sides of the mounting frame 22. The fixed gripper 62 is vertically disposed on the side of the suction cup assembly 23 and fixedly connected to the bottom surface of the mounting frame 22. The upper part of the movable gripper 63 is fixed below the output end of the linear drive mechanism 61, and the lower part of the movable gripper 63 is L-shaped and can fit against the fixed gripper 62. The linear drive mechanism 61 drives the movable gripper 63 to move up and down to cooperate with the fixed gripper 62 to grip the upper release paper 101. The linear drive mechanism 61 can be a pneumatic cylinder or an electric cylinder, etc. During operation, the multi-axis robotic arm 21 rotates to move multiple sets of suction cup assemblies 23 on the mounting frame 22 to the material bin 1 to pick up materials. Each set of suction cup assemblies 23 picks up a set of film 100 with upper and lower release papers. At the same time, the linear drive mechanism 61 drives the movable claw 63 downward to move it down so that the upper release paper clamping claw 6 opens. The lower part of the movable claw 63 moves to below the tear ear in the upper release paper 101. Then the linear drive mechanism 61 drives the movable claw 63 to move upward. At this time, the movable claw 63 lifts the tear ear of the upper release paper 101. When the upper release paper clamping claw 6 closes, the tear ear is clamped between the movable claw 63 and the fixed claw 62.

[0078] Because the release force of the adhesive sheet used for bonding power batteries is relatively small, and the strength of the upper release paper tear tab structure is limited, if the relative position between the upper release paper clamp 6 and the adhesive sheet 100 is not properly controlled, the tear tab may peel off or tear prematurely during the clamping process, thus affecting the tearing stability. Therefore, this invention incorporates process constraint design for the clamping height of the upper release paper clamp.

[0079] refer to Figure 6 When the upper release paper clamp 6 closes, the initial distance H from the bottom surface of the movable claw 63 in the upper release paper clamp 6 to the upper surface of the upper release paper 101 must be within the effective length S of the upper release paper tear ear and maintain a proportional relationship with S. Preferably, H=K·S, where K is a correction coefficient with a value range of 0.3~0.4, to avoid the tear ear being peeled off prematurely due to the clamping position being too high.

[0080] Furthermore, when the suction cup assembly 23 adopts a double accordion suction cup structure, the suction cup will undergo axial compression during the vacuum suction of the film 100, causing the film to shift upward relative to the upper release paper gripper 6. Therefore, considering the influence of the tear length and suction cup compression deformation, the actual clamping height H of the upper release paper gripper 6 is configured as H = K·S + L / 2, where K is a correction coefficient with a value ranging from 0.3 to 0.4. For example, when the effective length S of the upper release paper tear is 20 mm and the double accordion suction cup height L is 14 mm, the initial distance H from the bottom surface of the movable gripper 63 to the upper surface of the upper release paper is controlled within the range of 13 to 15 mm. Within this range, stable clamping of the upper release paper tear can be achieved, and the overall peeling of the upper release paper can be successfully completed after the film is adsorbed by the center shuttle table, thereby ensuring the reliability of the tearing process and providing a stable process basis for decoupling and improving the cycle time of the adhesive application process.

[0081] refer to Figure 5 When the upper release paper clamping claw 6 closes, the lower part of the movable claw 63 abuts against the bottom of the fixed claw 62, and the contact surfaces of the two are configured as bevels with matching shapes and serrated structures to increase the friction between the tear ears and improve the clamping firmness. At the same time, it can also prevent the tear ears from sticking to the upper release paper clamping claw 6 when the upper release paper is discarded and not easily detached.

[0082] refer to Figure 5 The suction cup assembly 23 is fixedly connected to the mounting frame 22 via several detachably fixed suction cup holders 24. Each suction cup holder 24 has a strip-shaped adjustment hole 25. The suction cup assembly 23 is detachably vertically inserted into the adjustment hole 25. By changing the installation and connection position of the suction cup assembly 23 and the adjustment hole 25, the distance between the suction cup assembly 23 and the upper release paper clamp can be adjusted. This allows for the matching of different types and sizes of film, achieving precise material picking and stable clamping, and enhancing the equipment's compatibility with different products.

[0083] refer to Figure 7 The release paper tearing mechanism 3 includes a flipping cylinder 31, a flipping shaft 32 fixedly connected to the output end of the flipping cylinder 31, and a plurality of paper tearing gripper assemblies 33 distributed along the axial direction of the flipping shaft 32. (Reference) Figure 8 and Figure 9The paper tearing gripper assembly 33 includes a vertically arranged upper fixed gripper 331, a lower movable gripper 332, and a lower gripper linear drive member 333. The upper fixed gripper 331 includes a connecting part 3311 and a clamping part 3312. The connecting part 3311 is vertically connected to the flipping shaft 32 and rotates synchronously. The clamping part 3312 is integrally formed and horizontally connected to the top of the connecting part 3311. The lower movable gripper 332 is located below the clamping part 3312. The lower gripper linear drive member 333 is vertically arranged and fixedly connected to the side of the connecting part 3311. The movable end of the top of the lower gripper linear drive member 333 is fixedly connected to the lower movable gripper 332. When the paper tearing gripper assembly 33 closes, the lower surface of the gripping part 3312 of the upper fixed gripper 331 abuts against the upper surface of the lower movable gripper 332, and the lower surface of the gripping part 3312 is provided with a serrated rough surface to increase the friction between it and the lower release paper tearing ear, while reducing the plane contact with the tearing ear, which helps to release the lower release paper when the paper tearing gripper assembly 33 opens.

[0084] During operation, the material handling gripper 2 picks up the film 100 with upper and lower release papers and moves it to the lower release paper tearing mechanism 3 to peel off the lower release paper 102: the lower jaw linear drive 333 drives the lower movable jaw 332 to move upward, the lower movable jaw 332 closes with the clamping part 3312 of the upper fixed jaw 331 and clamps the tearing ear part of the lower release paper 102, and the flipping cylinder 31 drives the flipping shaft 32 to drive the tearing gripper assembly 33 to rotate synchronously. Preferably, the flipping shaft 32 rotates to the side where the clamping part 3312 is located, separating the lower release paper 102 from the film 100.

[0085] refer to Figure 7 and Figure 9 Several locking blocks 34 are fixedly mounted on the flip shaft 32. The locking blocks 34 are connected to and fixed to the flip shaft 32 through a "C"-shaped slot. The connecting part 3311 of the upper fixing claw 331 rotates synchronously with the flip shaft 32 by fixing the locking blocks 34.

[0086] refer to Figure 7 Below the tearing gripper assembly 33 is a recycling bin 35 for collecting the lower release paper. A tilting shaft 32 passes through the upper part of the recycling bin 35. The recycling bin 35 surrounds the entire tearing gripper assembly 33 at its upper opening, receiving the peeled lower release paper. (Reference) Figure 9The connecting part 3311 is connected to an air pipe connector 3313 on its side. The air pipe connector 3313 is connected to an external air blowing device. An air blowing hole 3314 is provided on the upper end of the connecting part 3311 near the lower movable gripper 332. The air blowing hole 3314 is located at the part where the connecting part 3311 is connected to the clamping part 3312. An airflow channel 3315 is provided inside the connecting part 3311. The two ends of the airflow channel 3315 are respectively connected to the air pipe connector 3313 and the air blowing hole 3314. After the paper-tearing gripper assembly 33 tears off the lower release paper, the material-retrieving gripper 2 transfers the film stripped from the lower release paper to the centering shuttle table 4. At this time, the lower gripper linear drive 333 drives the lower movable gripper 332 to move downward, and the lower movable gripper 332 opens with the clamping part 3312. Simultaneously, the external air blowing device blows air through the air pipe connector 3313, airflow channel 3315, and air blowing hole 3314 to help blow the lower release paper 102 into the recycling bin 35 below, preventing it from sticking to the lower movable gripper 332 or the clamping part 3312. This achieves rapid and thorough peeling and automatic cleaning of the lower release paper, avoiding adhesion and ensuring smooth continuous operation.

[0087] refer to Figure 8 and Figure 9 A photoelectric detection switch 36 is also connected to the connecting part 3311. A sensing block 3321 is connected to the side of the lower movable gripper 332. The sensing block 3321 corresponds to the position of the photoelectric detection switch 36. The photoelectric detection switch 36 replaces the traditional magnetic switch, improving the stability of monitoring performance. The photoelectric detection switch 36 can sense and monitor the movement position of the lower movable gripper 332 in real time through the position of the sensing block 3321, thereby accurately and stably controlling the lower movable gripper 332 to close and clamp the lower release paper with the upper fixed gripper 331. In addition, the photoelectric detection switch 36 can also be configured to sense the material level height of the lower recycling bin 35, thereby monitoring the storage height of the lower release paper in the recycling bin 35 in real time, and transferring it in time when the bin is full.

[0088] refer to Figure 10The centering shuttle table 4 includes two sets of parallel servo linear modules 42. Each set of servo linear modules 42 is connected to a centering mechanism 43. The bottom of the two sets of centering mechanisms 43 are at different horizontal heights. The centering mechanism 43 is used to uniformly position multiple sets of films 100 at one time. The two sets of servo linear modules 42 drive the two sets of centering mechanisms 43, which are staggered in height, to reciprocate along their respective axial directions. The two sets of centering mechanisms 43 can alternately receive and position films at different height planes, realizing uninterrupted material supply and effectively matching the cycle time of high-speed production lines. Each set of centering mechanisms 43 is equipped with a positioning platform 44. Multiple spaced glue carriers 441 are arranged in parallel on the positioning platform 44. The glue carriers 441 have negative pressure channels inside for vacuuming. The upper surface of the adhesive carrier 441 is an anti-stick surface, which is a Teflon-coated surface, a silicone surface, or a structured surface with a micro-protrusion array, such as a serrated surface, to reduce the bonding area between the film 100 and the adhesive carrier 441, reduce the adhesion between the two, and facilitate the adhesive gripper 5 to quickly pick up the material from the adhesive carrier 441.

[0089] refer to Figure 11 The vacuum adsorption device 41 includes suction cups 411 and a vacuum generating device. The suction cups 411 are vertically inserted into the interior of the adhesive carrier stage 441, with at least four suction cups 411 connected inside each stage 441. They adsorb the film 100 from below and around the perimeter to fix the film and prevent displacement. The lower port of the suction cup 411 is connected to a negative pressure channel, and the vacuum generating device is connected to the negative pressure channel via a vacuum connector 442. The upper port of the suction cup 411 is located on the upper surface of the adhesive carrier stage 441 and is used to adsorb the film 100. The surface of the upper port of the suction cup 411 is an anti-stick surface, or it can be coated with an anti-stick liquid to prevent poor adhesion and separation from the film 100. During operation, after the lower release paper tearing mechanism 3 tears off the lower release paper 102, the material handling gripper 2 transports the film 100 with the upper release paper 101 to the adhesive table 441. The vacuum generator is activated, and the film 100 is adsorbed and fixed to the adhesive table 441 by the suction cup 411. Then the material handling gripper 2 moves up and retracts, while the upper release paper gripper 6 peels the upper release paper 101 from the surface of the film 100.

[0090] refer to Figures 10 to 12 The centering mechanism 43 is also equipped with a first positioning mechanism 45 and a second positioning mechanism 46 to synchronously center and adjust multiple sets of films, ensuring the accuracy and consistency of the adhesive application position. The positioning platform 44 is equipped with a first slide rail 443 and a second slide rail 444 perpendicular to each other, and a first limiting plate 445 and a second limiting plate 446 are fixed on two adjacent sides of the adhesive table 441.

[0091] The first positioning mechanism 45 includes a first driving device 451, a first driving plate 452 connected to the output shaft of the first driving device 451, a first sliding plate 453 fixedly connected to the first driving plate 452, and a plurality of first push blocks 454 fixed on the first sliding plate 453. The first driving device 451 can be a motor or a cylinder. The first driving device 451 is located below the positioning platform 44. The first driving plate 452 is vertically located on the side of the positioning platform 44. The first sliding plate 453 is parallel to and slidably connected to the first slide rail 443. The first push blocks 454 are located on the side of the glue carrier 441 and perpendicular to the first sliding plate 453. A first push plate 455 is connected to the side of the first push block 454. The first push plate 455 and the first limiting plate 445 are located on both sides of the glue carrier 441, respectively. The second positioning mechanism 46 includes a second driving device 461 located below the positioning platform 44. The second driving device 461 may be a motor. The output shaft of the second driving device 461 is connected to at least two lead screw drive shafts 463 via a synchronous belt 462. A second driving plate 464 is meshed on the lead screw drive shaft 463. The second driving plate 464 is vertically arranged and a second sliding plate 465 is fixedly connected to its upper end. The second sliding plate 465 is parallel to and slidably connected to the second slide rail 444. Several second push blocks 466 are fixed on the side of the second sliding plate 465. A second push plate 467 is connected to the side of the second push block 466 near the glue carrier 441. The second push plate 467 is perpendicularly distributed to the first push plate 455. The second push plate 467 and the second limiting plate 446 are located on both sides of the glue carrier 441, respectively. After the release paper gripper 6 peels the release paper 101 off the surface of the film 100, the vacuum generator releases the vacuum, the suction cup 411 releases the film 100, and the positions of multiple sets of films 100 can be uniformly adjusted on the adhesive table 441 through the first positioning mechanism 45 and the second positioning mechanism 46, so that the adhesive gripper can pick up the film and apply the adhesive, ensuring the accuracy and consistency of the adhesive application position.

[0092] Specifically, the first positioning mechanism 45 drives the first driving plate 452 to perform synchronous linear telescopic movement through the first driving device 451, and drives the first sliding plate 453 to slide linearly along the first slide rail 443. This further drives the first push block 454 and the first push plate 455 to push the film 100 against the first limiting plate 445 from the side, so that the upper limit of the film 100 in the X-axis direction is between the first push plate 455 and the first limiting plate 445. The second positioning mechanism 46 rotates through the second driving device 461, which drives the lead screw drive shaft 463 to rotate synchronously through the synchronous belt 462. The second driving plate 464 reciprocates along the axial direction of the lead screw drive shaft 463, thereby driving the second push block 466 and the second push plate 467 to push the film 100 against the second limiting plate 446 from the other side of the film 100, so that the upper limit of the film 100 in the Y-axis direction is between the second push plate 467 and the second limiting plate 446, thus achieving the centering adjustment of the film position.

[0093] refer to Figure 1 and Figure 13 The adhesive applicator 5 includes a spider-hand robot 51 and an adhesive applicator mechanism 52 connected below the spider-hand robot 51. The adhesive applicator mechanism 52 includes a drive motor 521 and a multi-suction cup mechanism 522 that rotates synchronously with the motor shaft of the drive motor 521. The spider-hand robot 51 drives the adhesive applicator mechanism 52 to pick up the adhesive sheet 100 from above the adhesive table 441 through the multi-suction cup mechanism 522. Then, the drive motor 521 drives the multi-suction cup mechanism 522 to rotate 90 degrees, and the adhesive sheet 100 is adhered to the vertical surface of the battery cell at the adhesive applicator station. The adhesive applicator mechanism 52 adopts a traditional adhesive applicator, and its internal structure and transmission principle will not be described in detail here.

[0094] The high-speed adhesive applicator of the present invention is also equipped with a visual inspection device. The visual inspection device is set between the lower release paper tearing mechanism 3 and the centering shuttle table 4, and can also be set on the material handling gripper 2. It is used to detect whether the lower release paper and the upper release paper of the film have been completely torn off.

[0095] refer to Figure 1 and Figure 2 The high-speed adhesive applicator of the present invention also includes a protective frame 7, which is installed outside the material bin 1, the material handling gripper 2, the release paper tearing mechanism 3, the centering shuttle table 4, and the adhesive applicator 5. The spider-hand robot 51 in the adhesive applicator 5 can be fixedly connected to the top of the protective frame 7. A monitoring screen can also be installed on the side of the protective frame 7 for real-time monitoring of the working status of the various electrical components inside the device. Figure 2 The center arrow indicates the direction, and the inner side of the protective frame 7 is also provided with a channel for the power supply core wire to pass through, so that the adhesive gripper 5 can continuously apply adhesive to the core wire flowing on the wire.

[0096] Another embodiment of the present invention provides a high-speed adhesive application method for pre-peeling the upper release paper, which uses the high-speed adhesive application device as described in any of the above embodiments and performs the following steps:

[0097] S1: Pick up and clamp the upper release paper: The picking gripper 2 picks up the film with upper and lower release papers from the hopper 1 and clamps the upper release paper of the film through the upper release paper clamp 6 integrated on it.

[0098] S2: Lower release paper tearing: The material handling gripper 2 transfers the film to the lower release paper tearing mechanism 3 to tear off the lower release paper;

[0099] S3: Top release paper tearing: The material grabber 2 transfers the film with the top release paper and places it on the centering shuttle table 4. The vacuum adsorption device 41 is activated to adsorb and fix the film. Then, when the material grabber 2 retracts, the top release paper is torn off from the adsorbed and fixed film through the top release paper gripper 6.

[0100] S4: Film position alignment: Turn off the vacuum adsorption device 41 and adjust the position of the film, which has had both upper and lower release papers removed, by using the alignment shuttle table 4;

[0101] S5: Cell Adhesive Application: The adhesive application gripper 5 picks up the adhesive film from the centering shuttle table 4 and applies it to the surface of the cell.

[0102] In step S2, the film can be inspected by a visual inspection device to confirm that the lower release paper has been completely removed; in step S3, the film can be inspected by a visual inspection device to confirm that the upper release paper has been completely removed.

[0103] This invention integrates the release paper peeling process with the material handling action, effectively reducing the workload of the adhesive applicator and simplifying the adhesive application cycle logic. It significantly improves the equipment cycle time and process compatibility in multi-specification parallel production scenarios, and is suitable for automated adhesive application production lines for new energy vehicle batteries, demonstrating good engineering application value.
