Description

TECHNICAL FIELD

[0001] The application relates to the technical field of lithium battery copper foil processing, in particular to a lithium battery copper foil multilayer composite pressing forming device. BACKGROUND

[0002] Lithium battery copper foil is one of the core key materials of lithium ion batteries, mainly serving as a negative electrode current collector, and plays an important role in collecting electrons, conducting current and supporting negative active materials. Its performance directly affects the energy density, cycle life, charging and discharging efficiency and safety performance of lithium ion batteries. High-quality lithium battery copper foil has the characteristics of thin thickness, smooth surface, high tensile strength, excellent electrical conductivity and strong corrosion resistance, and can meet the production needs of different types of lithium ion batteries. It is widely used in new energy vehicles, energy storage equipment, portable electronic devices and other fields. It is an indispensable basic material for the development of new energy industry. Lithium battery copper foil multilayer composite pressing is a key processing technology developed for the demand of high-performance lithium ion batteries. Its core is to stack and press multiple lithium battery copper foils and functional adhesive films in a predetermined order under a specific temperature, pressure and vacuum environment to form a stable structure with excellent performance. This process can effectively compensate for the shortcomings of single-layer copper foil in thickness, strength, and uniformity of electrical conductivity. Through interlayer synergistic effect, the overall tensile strength, electrical conductivity and cycle resistance of the composite structure are improved. It is an important supporting process for promoting the performance upgrade of lithium ion batteries and realizing large-scale and efficient production. In the prior art field, the existing equipment in the current lithium battery copper foil multilayer composite pressing forming field has the problem of low automation degree, which is difficult to meet the production needs of large-scale and high-precision. In the material pretreatment link, the traditional process relies on manual stripping of release film, which not only has high labor intensity and high labor cost, but also is easy to cause scratches and wrinkles on the surface of copper foil or adhesive film due to uneven manual operation force and non-standard action, affecting the subsequent composite quality. At the same time, the speed of manual release film stripping is limited, which cannot form efficient connection with the subsequent process. In the material stacking link, the existing technology mainly adopts simple manual stacking or semi-automatic stacking method, which is difficult to realize precise layering and arrangement of copper foil and adhesive film, and is easy to cause interlayer deviation and misalignment, thereby causing uneven interlayer bonding force of the product after pressing, and quality problems such as bubbles and delamination. In the pressing and material taking link, the workpiece taking and posture after pressing rely on manual or simple mechanical structure, which is easy to cause workpiece damage, and the taking efficiency is low, which cannot realize full-process automatic closed-loop production.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The adhesive film is pushed piece by piece to the discharge station by the stacking and unloading equipment. After the three-axis suction cup handling equipment picks up the adhesive film, it is transferred to the electric suction cup. The four corner electric suction cups fix the adhesive film from the bottom, completing the adhesive film handover. The horizontal moving platform drives the lifting platform and the adhesive film to the film-tearing station under the base frame. The first set of electric telescopic rods extends. Under the constraint of the limit telescopic components, the pressure roller is driven to compact the release film. The air knife sprays high-pressure airflow to make the corners of the release film curl up. The linear moving module drives the mounting plate to descend. The micro clamping module clamps the curled corners of the release film. The second electric telescopic rod is connected by a connecting rod. The micro clamping module is rotated to roll up the release film and expand the separation area. Then, the horizontal moving module drives the relevant structure to pull the release film, completing the peeling of the release film on the upper surface of the adhesive film. Subsequently, the lifting platform carries the adhesive film to the underside of the electric suction cup seat. After being adsorbed by the electric suction cup seat and rotated 180 degrees by the rotating module, it is transferred to the electric suction cup again. The above film peeling process is repeated to remove the release film on the lower surface of the adhesive film. After the double-sided film peeling is completed, the three-axis suction cup handling equipment transfers the adhesive film to the bracket of the chain stacking component and places it above the copper foil. The multi-layer stacking is completed in the order of copper foil-adhesive film-copper foil.

[0016] 2. After the copper foil and adhesive film are stacked according to the designed number of layers, the control panel starts the relevant actuators. The second ground rail drives the clamping robotic arm to move to the chain stacking component, clamps the stacked copper foil and adhesive film composite layer, and transfers it to the working chamber of the vacuum pressing equipment inside the third housing. Then, the clamping robotic arm and the second ground rail are reset. The vacuum pressing equipment performs high temperature, high pressure, and vacuum pressing and curing on the workpiece to form a firmly bonded composite structure. After pressing, the third electric telescopic rod retracts, and the cross telescopic frame is extended through the insertion rod and U-shaped frame, driving the electric suction cup frame to extend into the vacuum pressing equipment. The second motor drives the belt assembly to adjust the height of the lifting frame, so that the electric suction cup frame is attached to and adsorbed with the workpiece. Then, the cross telescopic frame retracts to remove the workpiece. The electric turntable drives the upper structure to turn to the right, and the micro electric telescopic rod drives the second rotating seat to rotate 180 degrees through the gear and rack assembly, so that the workpiece is flipped over and prepared for subsequent material discharge and inspection.

[0017] In summary, this invention achieves fully automated release film peeling through a fully automated process design, reducing manual labor intensity. Automated control also prevents damage such as scratches and wrinkles on the copper foil and adhesive film surfaces, ensuring the surface cleanliness and flatness of the pre-treated materials, laying a solid foundation for subsequent lamination processes. The automated peeling action can be precisely integrated with subsequent processes, significantly improving production cycle time. Furthermore, it achieves orderly layered stacking of the copper foil and adhesive film, ensuring precise interlayer positioning and uniform spacing, effectively avoiding interlayer offset and misalignment, thus improving the stability and consistency of the multi-layer composite structure. Finally, it automates workpiece unloading, orientation flipping, and transfer after lamination, effectively preventing workpiece damage and improving unloading efficiency.

It is equipped with an independent vacuum control system and is controlled by the control panel 5 to stably adsorb and rotate the pressed copper foil composite workpiece.

[0026] The specific work steps are as follows: Step 1: Before operation, the operator neatly places the stacked adhesive film into the stacking and unloading equipment 25, and starts the preset fully automatic processing flow through the control console 5. The control console 5 drives the second conveyor belt 24, the three-axis suction cup handling device 23, and the first motor 38 into working state in sequence according to the built-in control logic. The externally cut lithium battery copper foil is transported from the previous process to the second conveyor belt 24. The second conveyor belt 24 transports the copper foil in the front-back direction to the picking station of the three-axis suction cup handling device 23. The three-axis suction cup handling device 23 moves along the X, Y, and Z axes in a coordinated motion to suction the copper foil on the second conveyor belt 24. The copper foil is grasped and transferred to the two sets of brackets 35 at the top of the chain stacking component 3. The first motor 38 drives the long shaft 36 to rotate. The long shaft 36 drives the two sets of bevel gears 37 to drive synchronously, so that the mounting shafts 33 on the front and rear sides rotate synchronously in the same direction. The mounting shafts 33 further drive the corresponding chain assembly 34 to operate. The two sets of chain assemblies 34 move in a closed loop in the clockwise and counterclockwise directions respectively, driving multiple sets of brackets 35 to move synchronously inward in a circular motion, conveying the placed copper foil downward to the preset stacking height, reserving space for the next layer of material to be loaded, and realizing orderly spacing between layers. Step 2: The control console 5, following the timing logic, sequentially starts the stacking unloading device 25, electric suction cup 28, horizontal moving platform 26, first electric telescopic rod 217, air knife 219, linear moving module 222, micro clamping module 225, second electric telescopic rod 226, horizontal moving module 213, lifting platform 27, electric suction cup base 211, and rotating module 210. The stacking unloading device 25 pushes the stacked films one by one to the discharge station. The three-axis suction cup handling device 23 moves above the discharge station to vacuum-pick up individual films and transfer them to the electric suction cup 28. The electric suction cups 28, arranged at the four corners, stably adhere and fix the films from the bottom. Subsequently, the three-axis suction cup handling device 23 releases the upper suction. After the film is handed over, the horizontal moving platform 26 drives the lifting platform 27 and the film to move backward, conveying the film to the film-tearing station below the base frame 212. The two sets of first electric telescopic rods 217 extend synchronously. Under the guidance and constraint of the limiting telescopic component 216, they drive the pressure roller 218 and the air knife 219 to move downward respectively. The pressure roller 218 slightly compacts and positions the release film on the surface of the film. The air knife 219 moves to the outside of the edge of the release film and sprays out a high-pressure narrow airflow, causing the edge of the release film to automatically separate from the film substrate and lift up, forming a clampable film-tearing starting point. The linear moving module 222 drives the mounting plate 223 to move. Under the guidance of the first limiting component 221, the mounting plate 223 descends to the set height, so that the micro clamping module 225 is aligned and clamped. The second electric telescopic rod 226 extends from the corner of the already raised release film, driving the micro clamping module 225 to flip downwards around the first rotating seat 224 via the connecting rod 227, rolling the release film upwards and expanding the effective separation area. The horizontal moving module 213 drives the square sleeve 214 to move forward, causing the entire film-tearing mechanism to pull the release film backwards. With the positioning and cooperation of the electric suction cup 28, the release film on the upper surface of the adhesive film is completely peeled off. After the upper surface release film is removed, the lifting platform 27 rises, sending the adhesive film to the bottom of the two sets of electric suction cup seats 211. The electric suction cup seats 211 adsorb and fix the adhesive film from the top, and the bottom electric suction cup 28 releases adsorption and returns to its original position as the lifting platform 27 descends, completing the flipping and transfer of the adhesive film. The two sets of rotating modules 210 move in tandem. The electric suction cup holder 211 rotates 180°, flipping the entire adhesive film. The lifting platform 27 rises again, and the electric suction cup 28 re-adheres to the lower surface of the adhesive film. The electric suction cup holder 211 releases its grip, allowing the adhesive film to be transferred again. Subsequently, the horizontal moving platform 26, the lifting platform 27, and the electric suction cup 28 work together to send the flipped adhesive film back to the film-peeling station. The above film-peeling process is repeated to complete the fully automatic peeling of the release film from the lower surface of the adhesive film. After the release film on both sides is removed, the adhesive film is transferred to the picking position of the three-axis suction cup transport device 23. The three-axis suction cup transport device 23 adsorbs the clean adhesive film and places it on the bracket 35 of the chain stacking component 3, above the copper foil already placed. The chain stacking component 3 continues to operate, causing the adhesive film to descend to the designated layer.The multi-layer stacking is completed according to the sequence of copper foil, adhesive film, and copper foil; Step 3: After the copper foil and adhesive film are stacked according to the designed number of layers, the control panel 5 starts the second ground rail 228, the clamping robotic arm 229, the vacuum pressing device 43, the third electric telescopic rod 413, the second motor 49, the electric turntable 44, and the mini electric telescopic rod 423. The second ground rail 228 drives the clamping robotic arm 229 to move to the outside of the chain stacking component 3. The clamping robotic arm 229 clamps and picks up the stacked copper foil and adhesive film composite layer as a whole, and then moves it along the second ground rail 228 into the third cover. Inside the outer shell 42, the stacked workpiece is precisely placed into the working chamber of the vacuum pressing equipment 43. Then, the clamping robotic arm 229 and the second ground rail 228 are reset. The vacuum pressing equipment 43 performs lamination and curing on the internal workpiece under high temperature, high pressure, and vacuum conditions, causing the copper foil and adhesive film to form a dense and stable composite structure. After pressing, the third electric telescopic rod 413 retracts, pulling the insertion rod 412 forward along the slot seat 411, pushing the U-shaped frame 417 forward, and further driving the cross-type telescopic frame 416 to cross. The hinge point moves forward, causing the cross-type telescopic frame 416 to unfold and extend under the limiting constraint of the rotating rod 415. The two sets of meshing gear rods 419 move synchronously with the telescopic frame, pushing the second mounting base 418 to extend backward, so that the end electric suction cup frame 424 extends into the material picking station inside the vacuum pressing equipment 43. The second motor 49 drives the belt assembly 48 to rotate, and the belt assembly 48 drives the lifting frame 47 to make slight up and down adjustments under the guidance of the second limiting assembly 46, so that the electric suction cup frame 424 is in contact with the surface of the pressed workpiece. The bonding process forms a vacuum adsorption. After adsorption is complete, the third electric telescopic rod 413 extends, and the cross-type telescopic frame 416 retracts and resets, removing the molded composite workpiece from the vacuum pressing equipment 43. The electric turntable 44 drives the upper overall structure to rotate to the right discharge position, and the micro electric telescopic rod 423 extends, driving the gear and rack assembly 422 to move. The gear drives the second rotating seat 421 to rotate upward 180°, so that the electric suction cup frame 424 and the workpiece above it can be flipped simultaneously, providing a suitable posture for subsequent discharge. Step 4: The control console 5 starts the first ground rail 15, suction cup robotic arm 16, first conveyor belt 13, and vision inspection equipment 14. The first ground rail 15 drives the suction cup robotic arm 16 to move to the transfer station on the right side of the electric suction cup frame 424 inside the third housing shell 42. The suction cup robotic arm 16 adjusts its suction cup position to adhere to the surface of the workpiece on the electric suction cup frame 424 and form a vacuum adsorption. The electric suction cup frame 424 releases the adsorption, completing the automated transfer of the composite workpiece. The suction cup robotic arm 16, driven by the first ground rail 15, retreats back into the first housing shell 12 and places the workpiece on the first conveyor belt 13. The first conveyor belt 13 transports the formed workpiece from back to front, passing through the first housing shell 12 to the external discharge area. When the workpiece passes under the vision inspection equipment 14, the vision inspection equipment 14 performs a full-area appearance inspection of the workpiece surface, identifying defects such as pressing defects, bubbles, wrinkles, misalignment, and scratches, and feeds the inspection results back to the control console 5, realizing the automatic judgment and differentiation of qualified and unqualified parts.
