[0002] With the rapid development of the new energy industry, the market demand for energy storage batteries, as core components of energy storage, has seen explosive growth. Currently, mainstream energy storage battery assembly equipment generally uses automated production line operations, including basic modules such as loading, stacking, and welding. However, there are still many shortcomings in actual applications: traditional loading mechanisms lack precise battery posture adjustment and defect detection functions, resulting in stacking misalignment; transmission systems are mostly one-way linear layouts, with low space utilization and limited cycle time; quality inspections are often concentrated at the terminal, making it impossible to intercept defective products in real time, resulting in waste of materials and work hours. In addition, the existing equipment is not sufficiently automated, making it difficult to adapt to the production of batteries of multiple specifications, which restricts the improvement of production line efficiency and directly affects the consistency and safety of battery modules. Summary of the Invention

[0003] The main purpose of the present invention is to provide an energy storage battery assembly device, aiming to optimize the work process, improve work efficiency and reduce labor costs.

[0004] To achieve the above objectives, the present invention proposes an energy storage battery assembly device, comprising:

[0005] Feeding mechanism;

[0006] A stacking mechanism, the stacking mechanism being disposed adjacent to the loading mechanism, the loading mechanism moving a plurality of batteries one by one to the stacking mechanism, the stacking mechanism having a stacking plate for supporting the stacked batteries;

[0007] a strip rolling mechanism, the strip rolling mechanism being disposed adjacent to the stacking mechanism and having a pressing assembly for pressing the batteries on the stacking plate;

[0008] a welding mechanism, the welding mechanism being disposed adjacent to the strip rolling mechanism and capable of welding the battery and the electrode sheet placed on the battery;

[0009] The transmission mechanism sequentially connects the stacking mechanism, the strip rolling mechanism, and the welding mechanism. The stacking plate is arranged on the surface of the transmission mechanism. The transmission mechanism drives the stacking plate to pass through the stacking mechanism, the strip rolling mechanism, and the welding mechanism in sequence.

[0010] In a possible implementation, the feeding mechanism includes:

[0011] First feeding belt;

[0012] a second feeding belt, the second feeding belt being arranged perpendicular to the first feeding belt;

[0013] A steering assembly, which is arranged at the connection between the first feeding belt and the second feeding belt, and can turn the batteries on the first feeding belt and place them on the second feeding belt;

[0014] A tipping assembly is provided at the end of the second feeding belt, and the tipping assembly can lay the batteries on the second feeding belt flat one by one.

[0015] In a possible embodiment, the feeding mechanism further includes a height detection component and a thickness detection component, both of which are arranged between the steering component and the tipping component.

[0016] In a possible embodiment, the feeding mechanism further includes a conveyor belt, with two ends of the conveyor belt respectively located at the tipping assembly and the stacking mechanism, and a film positioning assembly is provided on the conveyor belt.

[0017] In a possible embodiment, a plurality of support bars are protruding from the surface of the stacking plate, and the batteries are placed on the support bars and form a rolling gap with the surface of the stacking plate.

[0018] In a possible implementation, the stacking mechanism further includes at least two limiting blocks, and the batteries are placed on the stacking plate in contact with the limiting blocks.

When the upper conveyor belt transports the stacking plate to the end, it is placed on the lifting assembly. The lifting assembly descends and places the stacking plate on the lower conveyor belt. The lower conveyor belt transports the stacking plate to the starting end of the upper conveyor belt, and is placed on the surface of the upper conveyor belt by another lifting assembly.

[0023] In a possible embodiment, a first conductivity test component and a second conductivity test component are further provided on both sides of the welding mechanism. The first conductivity test component is used to perform a conductivity test on a single battery before welding the electrode piece, and the second conductivity test component is used to perform a conductivity test on multiple batteries welded together after welding the stage piece.

[0037] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0038] Reference Figures 1 to 2 The present invention proposes an energy storage battery assembly device, including a feeding mechanism 1, a stacking mechanism 2, a strip rolling mechanism 3, a welding mechanism 4 and a transmission mechanism 5. The stacking mechanism 2 is arranged adjacent to the feeding mechanism 1, and the feeding mechanism 1 moves multiple batteries to the stacking mechanism 2 one by one. The stacking mechanism 2 has a stacking plate 21, and the stacking plate 21 is used to carry the stacked batteries; the strip rolling mechanism 3 is arranged adjacent to the stacking mechanism 2, and the strip rolling mechanism 3 has a pressing component 31, and the pressing component 31 presses the batteries on the stacking plate 21; the welding mechanism 4 is arranged adjacent to the strip rolling mechanism 3, and the welding mechanism 4 can weld the batteries and the pole pieces placed on the batteries; the transmission mechanism 5 connects the stacking mechanism 2, the strip rolling mechanism 3, and the welding mechanism 4 in sequence. The stacking plate 21 is arranged on the surface of the transmission mechanism 5, and the transmission mechanism 5 drives the stacking plate 21 to pass through the stacking mechanism 2, the strip rolling mechanism 3 and the welding mechanism 4 in sequence.

[0039] It can be understood that the loading mechanism 1 is responsible for transporting the individual batteries to the next workstation one by one in sequence. It can ensure that the batteries are moved one by one and accurately through a robotic arm, a conveyor belt or other automated equipment.

[0040] The stacking mechanism 2 is located adjacent to the loading mechanism 1. Its core component is the stacking plate 21, which serves as a platform for stacking batteries in layers. The loading mechanism 1 delivers batteries one by one to the stacking mechanism 2, where staff place them onto the stacking plate 21, which gradually forms a multi-layer battery stack.

[0041] The rolling mechanism 3 is used to physically fix the stacked battery packs. Its core component is the clamping assembly 31 such as a hydraulic or mechanical pressure plate, which compresses the batteries by applying pressure to prevent displacement. The stacked battery stack is then manually covered with a rolling belt to ensure close contact between the batteries for subsequent welding.

[0042] The electrode piece is a metal piece connecting the positive and negative electrodes of the battery. The welding mechanism 4 welds the battery pack and the electrode piece to ensure a stable electrical connection between the battery pack and the electrode piece.

[0043] The conveyor mechanism 5 connects all workstations in series to form an assembly line. It can be a pulley structure, a conveyor belt, or other structures. The stacking plate 21 is first placed on the conveyor mechanism 5. The conveyor mechanism 5 sequentially moves the stacking plate 21 to the stacking mechanism 2 for battery stacking, then to the stripping mechanism 3 for compaction and fixation, and finally to the welding mechanism 4 for welding the electrode sheets, achieving automated continuous production without the need for manual handling.

[0044] Through the above settings, most steps are completed collaboratively by mechanical mechanisms, reducing manual intervention. The batteries go through a standardized process from stacking to fixing to welding, which is suitable for the production lines of large-scale energy storage batteries such as power battery packs and energy storage power station battery modules.

[0045] Reference Figure 3 In one embodiment of the present invention, the feeding mechanism 1 includes a first feeding belt 11, a second feeding belt 12, a steering assembly 13 and a tipping assembly 14. The second feeding belt 12 is arranged perpendicular to the first feeding belt 11; the steering assembly 13 is arranged at the connection between the first feeding belt 11 and the second feeding belt 12, and the steering assembly 13 can turn the batteries on the first feeding belt 11 and place them on the second feeding belt 12; the tipping assembly 14 is arranged at the end of the second feeding belt 12, and the tipping assembly 14 can lay the batteries on the second feeding belt 12 flat one by one.

[0046] As can be understood, the first loading belt 11 and the second loading belt 12 are arranged vertically in an "L" shape. The first loading belt 11 is responsible for initial conveying, and the second loading belt 12 receives the turned batteries. The first loading belt 11 transports the batteries from the upstream process to the turning station, and the second loading belt 12 receives the turned batteries and arranges them in an alternating forward and reverse order to ensure the correct polarity direction of the batteries during subsequent stacking.

[0047] The steering assembly 13 is located at the connection between the first and second loading belts 12, and is used to rotate the batteries on the first loading belt 11 and transfer them to the second loading belt 12. Steering can be achieved through mechanical grippers, rotating platforms or guide rails, while controlling the positive and reverse directions of the batteries. For example, one positive pole of adjacent batteries faces left, and the next positive pole faces right, meeting the polarity matching requirements when the batteries are stacked.

[0048] The overturning component 14 is located at the end of the second loading belt 12, and pushes the upright batteries to be laid flat, changing from vertical to horizontal. This can be achieved by a cylinder push rod, a flipping robotic arm or an inclined slide, which facilitates the subsequent application of a film such as an insulating film to the battery surface, and laying it flat is more conducive to stable grasping and stacking by staff.

[0049] Reference Figure 3 In one embodiment of the present invention, the feeding mechanism 1 further includes a height detection component 15 and a thickness detection component 16 , both of which are arranged between the steering component 13 and the tipping component 14 .

[0050] It can be understood that the height detection component 15 is located on the second loading belt 12 after the steering component 13 and before the overturning component 14, that is, when the battery has completed the turn but has not yet been pushed over and laid flat, it is used to measure the height of the battery to determine whether it is within the allowable tolerance range. Laser ranging sensors, contact probes or visual inspection systems can be used to eliminate batteries with height deviations, such as abnormal batteries caused by expansion or poor assembly, to avoid excessive overall thickness or uneven welding pressure after stacking.

[0051] The thickness detection component 16 is arranged parallel to and adjacent to the height detection component 15 and is used to measure the thickness of the battery. Non-contact sensors such as infrared, ultrasonic sensors or precision roller pressure measurement can be used to identify batteries with abnormal thickness and prevent safety hazards caused by uneven force during stacking.

[0052] Reference Figures 1 to 3 In one embodiment of the present invention, the feeding mechanism 1 further includes a conveyor belt 17 , the two ends of the conveyor belt 17 are respectively located at the tipping assembly 14 and the stacking mechanism 2 , and a film positioning assembly 18 is provided on the conveyor belt 17 .

[0053] It can be understood that the conveyor belt 17 connects the overturning assembly 14 and the stacking mechanism 2 to form an independent transition transmission path, which receives the batteries laid flat by the overturning assembly 14 and smoothly conveys them to the entrance of the stacking mechanism 2.

[0054] The film positioning assembly 18 is mounted above the center of the conveyor belt 17 and straddles brackets on either side of the belt. When the battery is lying flat, it positions the battery, facilitating the automatic application of thin films, such as insulating film, to the battery surface. A mechanical baffle secures the battery's position on the conveyor belt 17, ensuring accurate film application. Both film application and positioning are completed simultaneously during the conveyor process, saving time in separate workstations.

[0055] Reference Figure 5 In one embodiment of the present invention, a plurality of support bars 22 are protruding from the surface of the stacking plate 21 , and the batteries are placed on the support bars 22 and form a rolling gap with the surface of the stacking plate 21 .

[0056] It can be understood that the support bars 22 on the stacking plate 21 are multiple parallel or cross-protruding bar structures, and the material can be metal or high-strength engineering plastics. They can lift the battery to a certain height so that a rolling strip gap is formed between the bottom of the battery and the surface of the stacking plate 21. The height of the support bar 22 is designed to be slightly larger than the thickness of the rolling strip 9, so that the rolling strip 9 can be placed in advance on the surface of the stacking plate 21. Before stacking, the metal rolling strip 9 or the fixed strip is spread flat on the surface of the stacking plate 21, in the gap between the support bars 22. When the batteries are placed one by one on the support bars 22, the rolling strip 9 naturally remains underneath. When the batteries reach the preset number of layers, they are transported to the rolling strip mechanism 3. The operator or the robot pulls up the two ends of the rolling strip 9 to quickly wrap the battery pack, eliminating the complicated step of "stacked and then threaded with the rolling strip" in the traditional process, reducing operation time and improving efficiency.

[0057] Reference Figure 4 In one embodiment of the present invention, the stacking mechanism 2 further includes at least two limiting blocks 23 , and the battery lamination limiting blocks 23 are placed on the stacking plate 21 .

[0058] It can be understood that the limit blocks 23 are used to limit the horizontal movement of the battery on the stacking plate 21 to ensure that the edges of each layer of batteries are aligned. At the same time, they also have a certain stacking guide function, preventing the battery from being cumulatively misaligned due to mechanical vibration or grasping errors when stacking multiple layers. The two limit blocks 23 can be L-shaped or bar-shaped, fixed above the stacking plate 21, and form a coordinated positioning with the support bar 22. The support bar 22 supports the bottom of the battery, and the limit blocks 23 constrain the side of the battery. Preventing battery stacking misalignment will cause uneven strapping or offset welding of the electrode, affecting electrical performance.

[0059] Reference Figures 1 to 2 In one embodiment of the present invention, the transmission mechanism 5 includes an upper conveyor belt, a lower conveyor belt and two lifting components 52. The lower conveyor belt is arranged parallel to the lower part of the upper conveyor belt, and the transmission direction is opposite to that of the upper conveyor belt; the two lifting components 52 are arranged at both ends of the upper conveyor belt and the lower conveyor belt. When the upper conveyor belt transports the stacking plate 21 to the end, it is placed on the lifting component 52. The lifting component 52 descends and places the stacking plate 21 on the lower conveyor belt. The lower conveyor belt transports the stacking plate 21 to the starting end of the upper conveyor belt, and is placed on the surface of the upper conveyor belt by another lifting component 52.

[0060] As can be understood, the upper conveyor belt is used to carry the stacking plates 21 and transport them in a forward direction, sequentially passing through the stacking, strip rolling, and welding stations. The lower conveyor belt, located below the upper conveyor belt and transporting in the opposite direction, is used to return empty stacking plates 21. There are two lifting assemblies 52, located at each end of the upper and lower conveyor belts, responsible for the vertical transfer of stacking plates 21 between the upper and lower layers. The layout of the upper and lower double-layer conveyor belts plus the lifting assemblies 52 achieves the circular transmission of stacking plates 21, significantly saving space on the production line while ensuring the continuity of the stacking, strip rolling, and welding processes.

[0061] The stacking plate 21 begins at the starting point of the upper conveyor, passing through the stacking mechanism 2 for battery stacking, the stripping mechanism 3 for strapping and securing, and the welding mechanism 4 for electrode welding. Once processed, the stacking plate 21 reaches the end of the upper conveyor, where the end lift assembly 52 lowers the plate 21 to the lower conveyor. The lower conveyor then reverses the motion, returning the empty plate 21 to its starting point. The starting lift assembly 52 then raises the plate 21 back to the upper conveyor, ready for the next stacking cycle. The double-layer layout reduces the footprint of the conveyor mechanism 5, making it suitable for compact production lines. Manual intervention is eliminated in the reflow of the plate 21, enabling fully automated production.

[0062] Reference Figures 1 to 2 In one embodiment of the present invention, a first conductivity test component 6 and a second conductivity test component 7 are further provided on both sides of the welding mechanism 4. The first conductivity test component 6 is used to perform a conductivity test on a single battery before welding the electrode piece, and the second conductivity test component 7 is used to perform a conductivity test on multiple batteries welded together after welding the stage piece.

[0063] Understandably, the first continuity test assembly 6 verifies that the cell voltage and internal resistance of a single battery are normal before electrode welding to prevent defective batteries from entering the welding process. After electrode welding, the second continuity test assembly 7 verifies the weld quality (such as cold joints, short circuits), the overall conductivity of the module, and the correct polarity of the connection of the completed multi-battery module.

[0064] After the batteries are stacked and before the electrode pieces are welded, the first conductivity test component 6 uses a probe or contact electrode to measure whether the open circuit voltage of the battery is within the rated range and whether the internal resistance is abnormally high. If the test fails, the staff removes the defective battery and the qualified battery continues to the welding station. The second conductivity test component 7 performs a circuit conductivity test on the welded battery module to confirm that there are no short circuits in the electrode welding; an insulation test to detect whether there are short circuits between the electrode pieces or with the casing; and polarity verification to check whether the series / parallel polarity is consistent with the design. Unqualified modules are marked and diverted to the rework line, and qualified modules enter the next process.

[0065] By introducing two-level continuity tests before and after the welding process, full-process quality monitoring of battery electrical performance is achieved, ensuring that battery cells and modules meet electrical safety standards before and after welding.

[0066] Reference Figures 1 to 2 In one embodiment of the present invention, the energy storage battery assembly device further includes a cleaning mechanism 8, which is arranged between the first conductivity test component 6 and the welding mechanism 4. The cleaning mechanism 8 is provided with a laser component for laser cleaning the battery surface.

[0067] Understandably, residual oxides, grease, or dust on the battery surface can lead to poor welding, such as cold joints and insufficient solder joint strength. Contamination at the interface between the electrode and the battery cell increases contact resistance, affecting the conductivity of the battery module. Furthermore, contaminants can create pores or cracks during welding, potentially triggering thermal runaway over long-term use.

[0068] Cleaning mechanism 8, located after the first continuity test assembly 6 and before the welding mechanism 4, first tests the battery's electrical performance and only cleans qualified batteries to avoid ineffective cleaning. A conveyor belt transports the batteries to the laser cleaning station, ensuring the laser beam is aligned with the area to be cleaned. Pulsed laser light is applied to the battery surface, instantly vaporizing or removing contaminants. An exhaust device is also installed to promptly remove vaporized residues from laser cleaning to prevent secondary contamination.

[0069] By introducing a laser cleaning process before welding, laser technology is used to remove pollutants on the battery surface such as oxides, oil stains, dust, etc., ensuring the reliability and consistency of subsequent welding.

[0070] Reference Figures 1 to 2 In one embodiment of the present invention, the cleaning mechanism 8 is further provided with a dust collection component 81, and the dust collection component 81 is provided adjacent to the laser component.

[0071] It is understandable that during the laser cleaning process, pollutants removed by the laser, such as metal oxides, dust, and organic matter vaporized residues, may re-attach to the battery surface or pollute the production line environment. The dust collection component 81 can be set to remove these residues in real time, ensure a stable cleaning effect, and maintain a clean working environment.

[0072] The dust collection component 81 is used to absorb particles vaporized or peeled off by the laser during laser cleaning to avoid secondary deposition; at the same time, it protects the optical system to prevent pollutants from blocking the lens or reflector of the laser component and affecting the laser accuracy; it maintains a clean workshop environment to avoid the spread of harmful dust such as nickel, cobalt and other metal particles, in compliance with industrial hygiene standards.

[0073] The technical solution of the present invention significantly improves production efficiency and product quality through highly automated and modular design. The feeding mechanism 1 adopts a double conveyor belt in conjunction with the steering and tipping assembly 14 to achieve precise orientation and posture adjustment of the battery, and integrates height / thickness detection to ensure that only qualified batteries enter the production line; the stacking mechanism 2 is designed with limit blocks 23 and support bars 22 to make the battery stack neatly and reserve rolling gaps, simplifying the subsequent fixing process; the upper and lower double-layer conveyor belts of the transmission mechanism 5 and the lifting assembly 52 form a closed-loop reflux system, saving space and ensuring continuous production; the welding mechanism 4 sets a two-stage conduction test before and after welding, combined with laser cleaning and dust collection assembly 81, to thoroughly remove pollutants from the welding surface and eliminate the risk of false welding or short circuit. Each workstation is closely coordinated, and the overall design combines high precision, high reliability and environmental protection. It is suitable for harsh scenarios such as power batteries and energy storage modules, greatly reducing the defective rate and maintenance costs, and is a model for intelligent battery production.
