Description

Technical Field

[0001] This utility model relates to the field of removing insulating tape from lithium batteries, specifically a tape-removing device. Background Technology

[0002] With the explosive growth of the new energy vehicle market, the demand for lithium-ion batteries is increasing. In the field of square lithium battery manufacturing, an insulating tape is applied to the surface of the aluminum casing of the battery, which plays a triple role of electrical insulation protection, mechanical buffer protection, and environmental isolation. The high insulation material blocks the direct contact between the aluminum casing and external conductors, effectively preventing the risk of short circuits. At the same time, it buffers the impact of external impacts on the aluminum casing and avoids cell damage caused by extrusion deformation. In addition, the tape layer can also block the intrusion of external dust and moisture penetration into the battery, improving the battery's environmental adaptability and long-term reliability.

[0003] However, when defective adhesive tape requires rework, the industry mainly uses two methods: manual peeling and mechanical peeling. While manual peeling can protect the integrity of the lithium battery's outer layer, it is inefficient and wastes manpower. Mechanical peeling mechanisms, on the other hand, work by gripping the edge of the tape with a clamping device and applying tension to peel it off. Although this improves efficiency, excess tape at the top is often completely compacted during the battery encapsulation process, forming a tightly adhered layer with no exposed edges. This causes traditional mechanical clamping methods to fail due to a lack of leverage points, and often even scratches the battery's outer layer.

[0004] In summary, existing lithium battery adhesive removal devices have problems such as high risk of battery damage, difficulty in removing adhesive, and low efficiency of manual adhesive removal, making it difficult to meet the requirements of current lithium battery production. Utility Model Content

[0005] The technical problem this invention aims to solve is the current difficulty of lithium batteries, which suffer from high risk of battery damage and low efficiency when the adhesive is removed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a peeling device, including a laser, a battery flipping mechanism, and a battery lifting and rotating mechanism; the laser is located above the battery flipping mechanism and the battery lifting and rotating mechanism, the battery flipping mechanism includes two symmetrical sets, and the battery lifting and rotating mechanism is located between the two sets of battery flipping mechanisms; the laser is capable of multi-dimensional movement.

[0007] This invention replaces traditional mechanical tape-tearing with laser thermal melting technology. Controllable laser energy is precisely applied to the adhesive layer, eliminating the risk of scratches, indentations, or cell deformation caused by mechanical clamping. It is particularly suitable for complex situations where compacted tape has no exposed edges, ensuring battery integrity and safety. Laser pretreatment reduces tape stickiness, eliminating the need for manual tearing by searching for peel points or pulling forcefully; a gentle pull is sufficient. This shortens tearing time, reduces labor intensity, and increases rework efficiency, significantly reducing human resource input and rework costs. Through the coordinated action of the battery flipping mechanism and the lifting and rotating mechanism, combined with the multi-dimensional movement of the laser, omnidirectional coverage of all six sides of the square lithium battery is achieved, precisely locating and completing the tape thermal melting process, solving the industry pain point that traditional mechanical tape tearing cannot handle compacted tape.

[0009] As a preferred embodiment of this invention, the laser includes a scanning galvanometer and a human-computer interaction device, wherein the scanning galvanometer is located below the laser and the human-computer interaction device is located above the laser.

[0010] The laser includes a scanning galvanometer, which allows the laser to dynamically adjust the width, length, and projection angle of the scanning lines to adapt to the geometric contours of different planes such as the large surface, bottom surface, and side surface of the battery.

[0011] As a preferred technical solution of this utility model, the battery flipping mechanism includes a push cylinder, a push block, a slide rail assembly and a bracket. The telescopic rod at the end of the push cylinder is connected to the push block. The push block is fixed to the bottom of the bracket, and the bottom of the bracket is provided with a slide rail assembly.

[0014] The battery flipping mechanism can flip all six sides of the square battery, ensuring that the insulating adhesive on each side can be irradiated by the laser.

[0015] As a preferred embodiment of this invention, the battery flipping mechanism further includes a protective pad located at the end of the battery fixing block.

[0016] The protective pads ensure that the battery retaining blocks will not damage the battery surface during the flipping process.

[0017] As a preferred technical solution of this utility model, the battery lifting and rotating mechanism includes a lifting cylinder, a fixing plate, and a mounting plate; the lifting cylinder is fixed to the working platform by the fixing plate, and the end of the telescopic rod of the lifting cylinder is rigidly connected to the mounting plate.

[0018] As a preferred technical solution of this utility model, the battery lifting and rotating mechanism further includes a rotating cylinder and a gripper. The rotating cylinder is fastened to the upper surface of the mounting plate, and its driving end is connected to the gripper in a transmission manner.

[0019] As a preferred technical solution of this utility model, it also includes a control system, wherein the laser, the battery flipping mechanism, and the battery lifting and rotating mechanism are all connected to the control system.

[0020] By using a unified automated control system to control the three groups of mechanisms, synchronous coordination can be achieved, thus improving efficiency.

[0021] The advantages of this utility model are: 1. Achieve non-destructive adhesive removal, significantly reducing battery damage risk: Laser hot melt technology replaces traditional mechanical clamping adhesive tape removal. Controllable laser energy is precisely applied to the adhesive layer, avoiding the risk of aluminum shell scratches, indentations, or cell deformation caused by mechanical clamping from the source. It is especially suitable for complex working conditions where the compacted adhesive tape has no exposed edges, ensuring battery integrity and safety.

[0022] 2. Significantly improves tape removal efficiency and reduces labor costs: Laser pretreatment reduces the tape's stickiness, eliminating the need for manual peeling to find a release point or pull forcefully; a gentle pull is sufficient. This shortens the time required for each peeling cycle, reduces labor intensity, increases rework efficiency, and significantly reduces human resource input and rework costs.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown in the figure, this utility model embodiment discloses a glue-removing device, including a laser fixing mechanism 1, a battery flipping mechanism 2, a battery lifting and rotating mechanism 3, and a laser 5.

[0028] Specifically, according to Figure 2 As shown, the laser fixing mechanism 1 includes a Y-axis module 11, an X-axis module 12, a Z-axis module 13, and a fixing platform 14.

[0029] See Figure 2The Y-axis module 11 comprises two sets, located on the upper wall of the fixed platform 15 on both sides in the width direction (assuming the width direction of the fixed platform 15 is the Y-axis direction, the length direction of the fixed platform 15 is the X-axis direction, and the direction perpendicular to the platform 15 is the Z-axis direction). The Y-axis module 11 consists of two rectangular columnar components with grooves in the middle of their left and right sides along the Y-axis direction, and their length is slightly narrower than the width of the fixed platform 15. The X-axis module 12 comprises one set, located on the upper wall of the Y-axis module 11, and is a rectangular columnar component with grooves in the middle of its front and rear sides along the X-axis direction, its length being the distance between the two sets of Y-axis modules 11. Two grooves are provided on the lower surfaces at both ends of the X-axis module 12, which cooperate with the slide rails of the Y-axis module 11, allowing the X-axis module 12 to slide freely along the grooves of the Y-axis module 11 in the Y-axis direction. The Z-axis module 13 comprises a set of rectangular columnar components with grooves on the middle of both sides along the Z-axis direction. The inner surface of the Z-axis module 13 has a groove, and the outer surface also has a groove. The groove on the inner surface mates with the slide rail of the X-axis module 12. The Z-axis module 13 is secured to the outer wall of the X-axis module 12, allowing it to slide freely in the X-axis direction. The fixed platform 14, located below the X, Y, and Z-axis modules, is a table consisting of multiple columns and a platform, used to fix the multi-dimensional movement modules.

[0030] See Figure 3 The battery flipping mechanism 2 includes two sets arranged symmetrically, specifically including a push cylinder 21, a push block 22, a slide rail assembly 23, a bracket 24, a servo motor 25, a clamping assembly 26, a battery fixing block 27, and a protective pad 28.

[0031] Specifically, the push cylinder 21 comprises two sets, fixed to both sides of the work platform. The push block 22 comprises two sets, each a rectangular component connected to the output end of the push cylinder 21. The slide rail assembly 23 comprises two sets, each comprising two slide rails, located between the two sets of push blocks 22. The bracket 24 comprises two sets, specifically including a bracket base and a column plate. The lower wall of the bracket base is provided with a sliding groove that can precisely match the slide rails of the slide rail assembly 23. The side of the bracket base is bolted to the push block 22. Since the bracket 24 is connected to the push cylinder 21 through the push block 22, and the bracket base is slidably connected to the slide rail assembly 23, the bracket 24 synchronously extends and retracts when the push cylinder 21 performs an extension and retraction movement. The servo motor 25 comprises two sets, respectively disposed on the top of the column plate of the bracket 24, arranged in the same direction as the push cylinders 21 on both sides. Two clamping assemblies 26 are included, each positioned opposite the servo motor 25, and the servo motor 25 is connected to the clamping assembly 26 via a coupling. Two battery retaining blocks 27 are included, rigidly fixed to the clamping assembly 26. The clamping assembly 26 and the battery retaining blocks 27 constitute a synchronously moving clamping actuator. Protective pads 28 are installed on the outer surface of the battery retaining blocks 27 to buffer mechanical stress and prevent damage to the battery's aluminum casing. In application, the clamping actuator formed by the clamping assembly 26 and the battery retaining blocks 27 can clamp the battery. The servo motor 25 drives the clamping assembly 26 and the battery retaining blocks 27 to rotate, thereby achieving the rotation of the battery.

[0032] See Figure 4 The battery lifting and rotating mechanism 3 includes a lifting cylinder 31, a fixing plate 32, a mounting plate 33, a rotating cylinder 34, and a gripper 35. The lifting cylinder 31 is located between the two battery flipping mechanisms 2. The fixing plate 32 is an L-shaped plate component, its bottom fixed to the worktable surface, and its sides fixedly connected to the sides of the lifting cylinder 31 for fixing the lifting cylinder 31. The mounting plate 33 is a rectangular plate component, its lower wall rigidly connected to the output end of the lifting cylinder 31. The mounting plate 33 can move vertically under the drive of the lifting cylinder 31. The rotating cylinder 34 is fastened to the upper surface of the mounting plate 33 with bolts. The gripper 35 is connected to the output end of the rotating cylinder 34 and can rotate at multiple angles following the rotating cylinder 34. The gripper 35 is made of a material with a hardness lower than the battery aluminum shell (such as polyurethane, silicone, and other polymer materials), effectively avoiding scratches or indentations on the aluminum shell during clamping. In application, the gripper 35 fixes the battery, the lifting cylinder 31 lifts the battery, and the rotating cylinder 34 rotates the battery.

[0033] See Figure 5 Battery 4 includes a large surface tape 41, a side tape 42, a top tape 43, and a bottom tape 44.

[0034] See Figure 2The laser 5 is fixed to a groove on the outer surface of the Z-axis module 13 via a mounting bracket. The groove engages with the slide rail of the Z-axis module 13, allowing the laser 5 to slide freely along the Z-axis. Combined with the Y-axis module 11, X-axis module 12, and Z-axis module 13, the laser 5 can move freely within a certain range in the X, Y, and Z directions. The laser 5 includes a scanning galvanometer that emits a high-energy-density linear beam to scan the insulating tape on the battery surface from all angles. The width, length, and projection angle of the scanning line can be dynamically adjusted to adapt to the geometric contours of different planes, such as the battery's large surface, bottom surface, and sides. Simultaneously, through a human-machine interface, operators can preset process parameters for different battery models, such as laser power and scanning time, achieving precise adjustments. This ensures that the energy is only enough to melt the adhesive layer, rendering it non-adhesive, but far below the energy threshold that could damage the battery's aluminum casing or internal cells, balancing flexibility and production consistency.

[0035] This device integrates an action timing management module. The actions of the servo motor, modules, laser, and cylinders are all automated through a self-developed PLC control system, achieving full-process automation control of "positioning-heat melting-relocation". During the battery flipping process, when the position of the battery to be scanned changes, the PLC controller adjusts the X, Y, and Z axis module motion trajectory of the laser fixing mechanism in real time to ensure that the laser 5 always maintains the optimal irradiation distance and angle, and that the laser scanning plane always accurately follows the battery surface. This dynamic adjustment mechanism effectively compensates for spatial position deviations during battery flipping, ensuring that the laser energy acts uniformly and omnidirectionally on the tape surface, achieving a stable and consistent heat melting effect.

[0036] See Figure 1 The working process of the device in this embodiment of the utility model is as follows: When the device is in operation, the battery 4 is first manually placed in the gripper 35 of the battery lifting and rotating mechanism 3. The lifting cylinder 31 then lifts it to the working height of the servo motor 25. At this time, the push cylinders 21 on both sides of the battery flipping mechanism 2 push the bracket 24 forward, and the battery is accurately fixed by the battery fixing block 27. The protective pad 28 relieves stress and prevents damage to the battery's aluminum shell. After the battery 4 is clamped, the lifting cylinder 31 resets, and the servo motor 25 drives the clamping assembly 26 to rotate the battery 90 degrees so that the large adhesive tape 41 faces the laser 5. At this time, the X, Y, and Z modules work together to move the laser 5 to the designated location and scan and heat-melt the large adhesive tape 41 and the top adhesive tape 43 of the battery. The servo motor 25 then continues to rotate the battery 90 degrees until the bottom is facing up, repeats the laser treatment, and then rotates it 90 degrees again to complete the heat-melting on the other side. After that, the battery is rotated 90 degrees and reset to the initial position. Then, the battery lifting and rotating mechanism 3 is activated, the lifting cylinder 31 rises, and the battery 4 is clamped by the gripper 35. The pushing cylinder 21 resets, and the rotating cylinder 34 rotates the battery horizontally by 90° to adjust its position. After the rotation is complete, the pushing cylinder 21 pushes the bracket 24 forward again to fix the battery, the lifting cylinder 31 resets, and the servo motor 25 drives the battery to flip 90 degrees, so that the side tape 42 and the top tape 43 are aligned with the laser 5 for heat melting. Then, it is flipped 180 degrees to process the other side. Finally, the battery is flipped 90 degrees and reset to the initial position. The lifting cylinder 31 clamps the battery upward, the pushing cylinder 21 resets, and the lifting cylinder 31 descends to release the battery, completing the laser pretreatment of all the tapes. At this time, the adhesiveness of the tapes is greatly reduced, making it easy to tear off manually and avoiding damage to the battery body.

[0037] This utility model application utilizes laser hot-melt technology to replace traditional mechanical tape-tearing. By precisely applying controllable laser energy to the adhesive layer, it avoids the risks of scratches, indentations, or cell deformation caused by mechanical clamping. This is particularly suitable for complex situations where compacted tape has no exposed edges, ensuring battery integrity and safety. Laser pretreatment reduces tape stickiness, eliminating the need for manual tearing by searching for peel points or pulling forcefully; a gentle pull is sufficient. This shortens tearing time, reduces labor intensity, and improves rework efficiency, significantly reducing human resource input and rework costs. Furthermore, through the coordinated action of the battery flipping mechanism 2 and the rotating mechanism, combined with the X, Y, and Z-axis linkage of the laser fixing mechanism 1, it achieves omnidirectional coverage of all six sides of the square lithium battery, precisely positioning and completing the tape hot-melt treatment, solving the industry pain point that traditional mechanical tape tearing cannot handle compacted tape.
