Description

Technical Field

[0001] This utility model relates to the field of battery sealing technology, and in particular to a fully automatic three-channel aluminum foil sealing machine for batteries. Background Technology

[0002] Battery sealing refers to the process of sealing the electrolyte filling holes or terminals with aluminum foil after the battery is assembled. This process ensures the sealing of the electrolyte inside the battery, prevents leakage and the intrusion of external contaminants, and maintains the stability of the internal chemical environment. It is a key step in ensuring the safety, reliability, and extended service life of the battery.

[0003] However, existing battery sealing machines rely on semi-automatic or single-channel sealing equipment, which generally suffer from low efficiency and low production efficiency. The single-station, one-by-one processing method makes it difficult to achieve large-scale, efficient production. At the same time, it requires a lot of manual intervention for loading, unloading, positioning, or starting, resulting in high labor costs. Furthermore, it cannot quickly adapt to batteries of different specifications and sizes. For example, a typical single-channel heat sealing machine is equipped with only one heat sealing head and one conveyor line. During operation, workers manually place the battery into a fixed position on the conveyor belt. The machine then transports the battery to the sealing station, where the heat sealing head descends to complete a single seal. The battery is then ejected, and a worker or robotic arm removes it to place the next battery to be sealed. During this process, the lifting and lowering adjustment of the heat sealing mechanism may not be precise enough, leading to uneven sealing pressure. More importantly, the entire cycle time is limited by the operating time of a single heat sealing head and the waiting time between preceding and following processes. When faced with large orders, this single-channel serial working mode inevitably leads to a bottleneck in production efficiency, and the entire process remains highly dependent on manual labor. Three-channel synchronous sealing and automatic clamping and positioning directly double the theoretical production capacity of traditional equipment and significantly reduce manual intervention. Utility Model Content

[0004] This utility model discloses a fully automatic three-channel aluminum foil sealing machine for batteries, aiming to solve the technical problems of existing battery sealing machines, such as low efficiency, low production efficiency, single-station processing, difficulty in achieving large-scale and efficient production, the need for a lot of manual intervention for loading, unloading, positioning or starting, resulting in high labor costs, and the inability to quickly adapt to batteries of different specifications and sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fully automatic three-channel aluminum foil sealing machine for batteries includes a support base and a reinforcing plate fixedly connected to the middle of the support base. A unwinding seat is fixedly connected to the top left side of the support base, and a first steering roller is slidably connected to the bottom of the unwinding seat. A feeding seat is provided on the reinforcing plate, and a battery is placed on top of the feeding seat. The machine also includes: a heat sealing mechanism: the heat sealing mechanism includes a connecting seat fixedly connected to the top of the support base, a lead screw threadedly connected to the middle of the connecting seat, a lifting plate rotatably connected to the bottom of the lead screw, a mounting plate fixedly connected to the bottom of the lifting plate, a hydraulic rod fixedly connected to the middle of the bottom of the mounting plate, and a heating seat fixedly connected to the bottom end of the hydraulic rod; and a conveying mechanism: the conveying mechanism is fixedly connected to the top of the reinforcing plate, and the battery is placed on top of the conveying mechanism.

[0006] By adopting the above technical solution, a precision heat-sealing system integrating three-channel parallel operation and graded pressure control is constructed. This achieves precise control over sealing quality while fundamentally doubling production efficiency. The core of this mechanism lies in its efficient integration of macroscopic height adjustment, microscopic process pressure control, and a multi-channel synchronous operation strategy. Specifically, three independent mounting plates, along with their bottom hydraulic rods and heating seats, form three parallel heat-sealing stations under the support of the lifting plate. This allows the equipment to seal three batteries simultaneously, directly increasing the theoretical output of a single operation cycle to several times that of traditional single-channel equipment, greatly optimizing the production cycle. Furthermore, by rotating the lead screw located in the middle of the connecting seat, the operator can drive the entire lifting plate to move smoothly up and down along the guide rod over a wide range. This coarse adjustment process can quickly adapt to the overall height of different product series. Each channel's mounting plate can also be independently fine-tuned for alignment, and finally, each hydraulic rod independently drives its heating seat to press against the corresponding battery sealing surface with constant and programmable pressure. This innovative architecture of "three-channel parallel operation, screw-based coarse positioning, and hydraulic rod-based fine pressing" not only breaks through efficiency bottlenecks through parallel processing, but also effectively overcomes problems such as poor sealing or aluminum foil damage caused by pressure fluctuations or misalignment in traditional equipment through hierarchical control. Thus, it can still stably output high-quality seals with excellent airtightness and consistency under high-speed production conditions.

[0007] As a further embodiment of this utility model: the conveying mechanism includes a transmission roller fixedly connected to the top of the reinforcing plate, a gear fixedly connected to the front side of the transmission roller, a gear chain drivingly connecting the gears, a servo motor at the bottom of the transmission roller, a sliding plate at the top of the feeding seat, a fixing pin inserted inside the sliding plate, a guide rail fixedly connected to the inner side of the sliding plate, and a fixing clamp fixedly connected to the inner side of the guide rail.

[0008] By adopting the above technical solution, an automated conveying system integrating synchronous transmission, flexible positioning, and intelligent sensing was used to solve the efficiency bottlenecks and specification compatibility issues in the production process. This mechanism, powered by a servo motor and a transmission system composed of gears and chains, ensures that all transmission rollers rotate in perfect synchronization, providing a stable base for the battery without slippage or speed difference. The mechanism's innovation is particularly evident in its positioning and clamping unit: by loosening the fixing pin, the position of the sliding plate on the feeding seat can be easily adjusted, thereby changing the distance between the guide rails on both sides, allowing the production line to quickly switch to accommodate battery products of different widths. When the battery is conveyed to the heat-sealing station by the synchronously driven rollers, the sensor inside the fixed fixture detects the workpiece's arrival in real time, triggering the actuator to drive the guide rails and fixtures on both sides to move towards the center, completing the precise clamping and rigid fixation of the battery, providing a zero-displacement reference for the subsequent heat-sealing process. This device not only automates the entire process from conveying and testing to clamping, eliminating cycle delays and uncertainties caused by manual intervention, but its flexible design also enables a single unit to cover a wider range of products, greatly improving equipment utilization and the overall efficiency of the production line.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. Adopting an innovative architecture of "three-channel parallel operation, screw-based coarse positioning, and hydraulic rod-based fine pressing", production efficiency has been doubled. At the same time, the pressure and position of the sealing process are precisely controllable. Thus, even under high-speed production conditions, it can still stably output high-quality and highly consistent airtight seals, and has excellent flexibility to quickly adapt to different product specifications.

[0010] 2. The system adopts a conveying system that integrates synchronous transmission, flexible positioning and intelligent sensing, realizing full automation of the battery conveying, precise positioning and rigid clamping process. This not only greatly improves the production cycle and process stability, but its flexible width adjustment capability also allows a single machine to quickly adapt to a variety of products, significantly improving the utilization rate of the equipment and the overall efficiency of the production line.

[0023] 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.

[0024] Reference Figures 1 to 5The fully automatic three-channel aluminum foil sealing machine for batteries includes a support base 1 and a reinforcing plate 2 fixedly connected to the middle of the support base 1. A unwinding seat 3 is fixedly connected to the top left side of the support base 1, and a first steering roller 4 is slidably connected to the bottom of the unwinding seat 3. A feeding seat 12 is provided on the reinforcing plate 2, and a battery 5 is provided on the top of the feeding seat 12. The machine also includes: a heat sealing mechanism: the heat sealing mechanism includes a connecting seat 6 fixedly connected to the top of the support base 1, a lead screw 7 threadedly connected to the middle of the connecting seat 6, a lifting plate 8 rotatably connected to the bottom of the lead screw 7, an mounting plate 9 fixedly connected to the bottom of the lifting plate 8, a hydraulic rod 10 fixedly connected to the bottom center of the mounting plate 9, and a heating seat 11 fixedly connected to the bottom end of the hydraulic rod 10; and a conveying mechanism: the conveying mechanism is fixedly connected to the top of the reinforcing plate 2, and the battery 5 is placed on the top of the conveying mechanism.

[0025] Specifically, by manually rotating the lead screw 7, the threaded connecting seat 6 is driven, thereby causing the entire lifting plate 8 to make precise and wide-range vertical displacements along the guide rod, achieving a rapid and stable initial working height setting for the heat sealing system to adapt to the overall height of different product series. The second stage is independent channel fine-tuning, which allows the three mounting plates 9 to slide independently back and forth on the slide rails at the bottom of the lifting plate 8, so that each heat sealing head can be laterally aligned with a specific sealing point on the battery 5. The third stage is channel-specific precision pressing, using the hydraulic rod 10 as the final actuator. After receiving a control signal, it independently drives the heating seat 11 to make a small-stroke precision downward press along the guide rod on the mounting plate 9. The pressure provided by the hydraulic medium is constant and precisely controllable, ensuring that each heating seat 11 applies a preset and uniform clamping force to the workpiece at the moment of sealing. The three heat sealing channels can achieve true parallel synchronous operation without sacrificing individual pressing quality, improving work efficiency.

[0026] The connecting seat 6 has a threaded seat corresponding to the lead screw 7 in the middle. Through the threaded transmission principle between the lead screw 7 and the threaded seat, the operator can rotate the hand valve to realize the smooth, precise and self-locking vertical displacement of the lifting plate 8 and the entire heat sealing unit it carries. This allows for quick setting of the initial working height to accommodate batteries 5 of different specifications. Guide rods are provided on the left and right sides of the lead screw 7. The top of the guide rod is slidably connected inside the connecting seat 6, and the bottom of the guide rod is fixedly connected to the top of the lifting plate 8. The guide rods effectively constrain the degree of freedom of the lifting plate 8 during the lifting process, completely preventing radial offset or rotation, and ensuring the linear accuracy and stability of the lifting motion. A hand valve is provided at the top of the lead screw 7.

[0027] The device includes three mounting plates 9, which are equidistantly positioned at the bottom of the lifting plate 8. The mounting plates 9 can slide back and forth via a slide rail on the top of the lifting plate 8. Guide rods are provided on the left and right sides of the top of the heating seat 11, and the top of the guide rods are slidably connected inside the mounting plates 9. The independent sliding capability of each mounting plate 9 on the slide rail allows the operator to make precise lateral alignment adjustments to a single heating seat 11 based on the actual position of a specific sealing point on the battery 5. This greatly enhances the adaptability of the equipment to different product models and the accuracy of the sealing position.

[0028] Reference Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In a preferred embodiment, the conveying mechanism includes a transmission roller 13 rotatably connected to the middle of the feeding seat 12 and fixedly connected to the top of the reinforcing plate 2. A gear 14 is fixedly connected to the front side of the transmission roller 13, and a gear chain 15 is connected between the gears 14. A servo motor 16 is provided at the bottom of the transmission roller 13. A sliding plate 17 is provided at the top of the feeding seat 12. A fixing pin 18 is inserted into the sliding plate 17. A guide rail 19 is fixedly connected to the inner side of the sliding plate 17, and a fixing clamp 20 is fixedly connected to the inner side of the guide rail 19.

[0029] Specifically, the servo motor 16 serves as the power source, driving the tightly meshed gear 14 and gear chain 15 system to synchronously distribute power to all transmission rollers 13, ensuring that the linear velocity of all roller surfaces on the conveyor line is consistent, providing a stable conveying base for the battery 5 without slippage or speed difference. For width adaptation, by releasing the locking pin 18, the position of the sliding plate 17 on the unloading seat 12 can be manually adjusted, thereby changing the width of the conveying channel formed by the guide rails 19 on both sides, giving the production line the flexibility to quickly respond to the width of products of different specifications. When the battery 5 is conveyed to the sealing station, the sensor inside the fixing fixture 20 uses a photoelectric sensor to detect the workpiece arrival signal in real time. This signal immediately triggers a clamping program driven by a pneumatic or hydraulic actuator, pushing the guide rails 19 on both sides and the fixture to move synchronously towards the center, completing the precise clamping and rigid fixation of the battery 5.

[0030] The device includes multiple drive rollers 13 and gears 14. The multiple drive rollers 13 are equidistantly rotatably connected to the middle of the feeding seat 12. The multiple equidistantly distributed drive rollers 13 provide a continuous and uniform support plane for the battery 5, effectively avoiding the sinking, deformation or jamming of the workpiece due to insufficient support during the conveying process, and ensuring the stability of the conveying process. The servo motor 16 is fixedly connected to the bottom of the feeding seat 12 through the motor plate, and one of the gears 14 is fixedly connected to the end of the drive shaft of the servo motor 16.

[0031] The device includes four sliding plates 17, which are slidably connected to the top of the feeding seat 12 near the four corners via extension plates. The sliding plates 17 are fixedly connected to the upper part of the extension plates by fixing pins 18. By releasing the locking of the fixing pins 18, the position of the sliding plates 17 can be flexibly adjusted, thereby changing the width of the conveying channel formed by the guide rails 19 on both sides. This design gives the equipment excellent flexibility to quickly adapt to different specifications of batteries 5. There are two fixing clamps 20, which are fixedly connected to the middle of the guide rails 19. Sensors are set inside the fixing clamps 20. The cooperation between the sensors set inside the fixing clamps 20 and the actuators realizes the closed-loop control of automatic detection and precise clamping of the workpiece in place, ensuring that each battery 5 can be stably held on the preset reference during the heat sealing process.

[0032] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the number of unwinding seat 3, second steering roller 21, cutter 22 and bonding seat 23 are all three. The three second steering rollers 21 are fixedly connected at equal intervals on the left side of the lifting plate 8, and the three cutters 22 and bonding seats 23 are fixedly connected at equal intervals on the right side of the mounting plate 9.

[0033] Specifically, the design of the second steering roller 21 fixed to the left side of the lifting plate 8 ensures that when the height of the lifting plate 8 is adjusted by the lead screw 7 to accommodate different specifications of batteries 5, the guide path of the aluminum foil can be adjusted synchronously, always maintaining the correct relative position with the heat sealing station. When the battery 5 is sealed and transported to the cutting station, the pressing cylinder in the bonding seat 23 of the channel will precisely press its aluminum foil strip to provide the necessary tension, and then the cutter 22 of the same group will perform the cutting, completing the separation of the tail of the current battery 5 from the head of the next battery 5.

[0034] Working Principle: During operation, three independent unwinding seats 3 each carry an aluminum foil roll. After being turned and tensioned by the first steering roller 4 and the second steering roller 21, the aluminum foil strip is precisely guided to the heat-sealing station area. Simultaneously, the battery 5 to be sealed is placed on the conveyor line. The servo motor 16 drives all the transmission rollers 13 to rotate synchronously through the gear 14 and gear chain 15 transmission system, providing a stable conveying base for the battery 5. Before the battery 5 enters the heat-sealing station, the operator can adjust the position of the sliding plate 17 by pulling out the fixing pin 18, thereby changing the spacing of the guide rails 19 on both sides to accommodate different product specifications. After adjustment, the fixing pin 18 is reinserted to fix the guide rails 19. When the battery 5 is conveyed to the heat-sealing station, the sensor inside the fixing clamp 20 detects the workpiece arrival signal, triggering the actuator to drive the fixing clamp 20 to move towards the center, completing the precise clamping and rigid fixation of the battery 5. The heat-sealing mechanism then begins operation: Before heat sealing, the operator can adjust the overall height of the lifting plate 8 by rotating the lead screw 7 to accommodate batteries 5 of different specifications. Next, the three mounting plates 9 can be independently fine-tuned on the slide rails at the bottom of the lifting plate 8, ensuring that each heating seat 11 is precisely aligned with a specific sealing point on the battery 5. Finally, each hydraulic rod 10 independently drives the heating seat 11 to precisely press down along the guide rod on the mounting plate 9, pressing the aluminum foil onto the sealing surface of the battery 5, completing the heat sealing. During this process, the three aluminum foil strips are continuous, being pulled forward as the battery 5 is intermittently conveyed. After the heat sealing process is completed, the hydraulic rod 10 drives the heating seat 11 to return to its original position and rise. The fixing clamp 20 releases its clamp on the battery 5, and the clamp loosens. The conveying mechanism restarts, conveying the first battery 5 forward one station. Simultaneously, the second battery 5 has been conveyed to the heat-sealing station and is clamped and heat-sealed. When the first battery 5 arrives at the cutting station, the aluminum foil behind it is in front of the heat-sealing station of the second battery 5. At this time, the sensor at the cutting station triggers two actions: first, the pressing cylinder actuates, pressing down on the aluminum foil strip to provide it with stable downward pressure and tension; then, the cutter 22 actuates, cutting the aluminum foil behind the pressing point. This cutting not only completes the sealing of the tail of the first battery 5, but also completes the pre-cutting of the head of the second battery 5. This cycle continues, with each battery 5 moving to the cutting station for the final cutting of its tail after being sealed at the heat-sealing station, while simultaneously cutting the head of the next battery 5.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
