Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to an angle-adjustable bending device and battery production equipment for the cell packaging process. Background Technology

[0002] In battery cell packaging, the corner bending process significantly impacts the forming quality of the cell's edges and corners. Current mainstream corner bending devices employ a fixed-angle design, meaning the spatial orientation of the bending execution unit cannot be dynamically adjusted. When the production line needs to process battery cells of different specifications, the relatively fixed position of the cells on the transfer fixture, coupled with the fact that the fixed corner bending device can only accommodate a single corner angle, often necessitates downtime to replace specialized molds or adjust the overall machine layout. This not only disrupts production continuity but also increases changeover time and labor costs. More importantly, when batch variations in the battery cell's edge geometry cause changes, the fixed-angle device may fail to adequately fit the corner area, affecting bending accuracy and packaging sealing. While some improvements attempt to introduce multi-station turntables, these solutions increase structural complexity and maintenance costs, and still struggle to achieve continuous angle adjustment. Therefore, a basic structural solution that can flexibly adapt to multi-angle processing requirements is urgently needed. Utility Model Content

[0003] In view of this, the present invention provides an angle-adjustable bending device and battery production equipment, which can adapt to bending requirements of different angles and has good processing flexibility.

[0004] The objective of this utility model is achieved through the following technical solution: An angle-adjustable bending device includes an angle-adjusting component and a bending component; the angle-adjusting component includes an angle-adjusting reference component and a sliding component, and the bending component is disposed on the sliding component; the sliding component is slidably connected to the reference surface of the angle-adjusting reference component, and the reference surface is constructed as an arc-shaped sliding trajectory surface.

[0005] By utilizing the arc-shaped sliding trajectory surface of the angle adjustment reference component in conjunction with the sliding component, a continuously adjustable angle adjustment basic structure is constructed. The free sliding of the sliding component along the arc-shaped trajectory allows the angle adjustment assembly to adapt to any angle requirement, overcoming the technical deficiency of traditional fixed angle adjustment devices in handling multi-angle processing. Because the arc-shaped trajectory surface provides continuous path guidance, the angle adjustment process of the angle adjustment assembly does not require disassembly or replacement of parts, simplifying the operation process.

[0006] This structural design directly enhances the versatility of the device. The fixed connection between the angle-folding component and the sliding element ensures the stability of the processing unit during angle adjustment, avoiding deviations in angle-folding accuracy caused by component displacement. The physical constraint characteristics of the arc-shaped trajectory surface prevent the sliding element from derailing, ensuring mechanical reliability for long-term use. The overall structure achieves basic angle adaptation without relying on a complex control system, reducing manufacturing costs and maintenance difficulty, and providing a universal solution for angle-folding processing of multi-specification battery cells in battery production.

[0007] Preferably, the angle adjustment reference component has an angle adjustment scale on its surface perpendicular to the reference plane; the slider is provided with a pointer, which is aligned with the angle adjustment scale.

[0008] The alignment of the angle adjustment scale and pointer forms an intuitive visual positioning system. Operators can directly read the current angle by the real-time position of the pointer on the scale, eliminating the need for experience-based estimation or external measuring tools required by traditional devices. This structure lowers the operational threshold for angle adjustment and reduces the risk of human error. The geometric matching of the scale markings and the curved trajectory surface ensures the linear accuracy of the angle indication, enabling even non-professionals to quickly and accurately adjust the angle. The visual assistance system operates without power, enhancing the equipment's applicability in unpowered environments.

[0009] Preferably, it further includes an adjustment component, which includes a horizontal adjustment component and a vertical adjustment component; the horizontal adjustment component is disposed on the moving end of the vertical adjustment component; and the angle adjustment reference component is fixedly connected to the moving end of the horizontal adjustment component.

[0010] The hierarchical structure of the adjustment components enables three-dimensional spatial positioning. The vertical adjustment component, supporting the horizontal adjustment component, forms the initial vertical positioning reference. The horizontal adjustment component provides secondary translational freedom at its moving end. Finally, the angle adjustment module and displacement adjustment module are integrated into a unified system through the fixed connection of the angle adjustment reference component. This structure allows the angle-adjusting device not only to adjust the angle but also to compensate for the cell's positional deviation in the fixture. When the cell's processing position changes due to incoming material tolerances or clamping offsets, the adjustment sequence of first lifting and then translating can efficiently correct the coordinates of the angle-adjusting point, significantly reducing the dependence on the positioning accuracy of the preceding process.

[0011] Preferably, the horizontal adjustment component includes a horizontal drive component and a translation block; the translation block is connected to the output end of the horizontal drive component, and the translation block is fixedly connected to the angle adjustment reference component.

[0012] The mechanical transmission design of the horizontal drive component and the translation block provides stable linear displacement output. The translation block, acting as a power transmission intermediary, converts the output of the drive component into the linear motion of the angle adjustment reference component. Its rigid connection characteristics prevent position drift during transmission. This structure is particularly suitable for production line environments requiring high-frequency position fine-tuning. The large contact area of ​​the translation block disperses the motion load, reducing wear on the drive component. The fixed connection ensures that horizontal displacement is transmitted to the angle adjustment module without delay, maintaining consistency in the processing position.

[0013] Preferably, the vertical adjustment component includes a vertical drive component and a lifting block; the lifting block is connected to the output end of the vertical drive component, and the horizontal adjustment component is installed on the lifting block.

[0014] The lifting block, acting as the actuator of the vertical drive component, provides a stable lifting platform for the horizontal adjustment module. Its support-type mounting structure forms a rigid whole between the horizontal adjustment component and the lifting block, preventing swaying caused by layered installation. When handling battery cells of varying thicknesses, the vertical displacement of the lifting block can quickly match the cell's bend height requirements. This design optimizes the force transmission path; the output force of the vertical drive component acts directly on the load through the lifting block, reducing energy loss in intermediate stages and improving the timeliness of the lifting response.

[0015] Preferably, the adjustment component is equipped with a photoelectric sensor, which is used to detect vertical displacement and horizontal displacement.

[0016] The displacement detection function of the photoelectric sensor establishes a position feedback mechanism. By monitoring vertical and horizontal movement in real time, positioning deviations can be detected promptly and compensation actions can be triggered. This non-contact detection avoids mechanical wear and is suitable for high-speed continuous operation environments. Sensor data directly reflects the actual displacement, providing a foundation for closed-loop control and helping to improve positioning accuracy. Dual-axis detection capability covers the main motion dimensions of the adjustment components, forming a complete displacement monitoring system.

[0017] Preferably, the bottom surface of the angle adjustment reference component is provided with a plurality of locking holes, and the sliding component is provided with a locking through groove, wherein the locking through groove and any of the locking holes are detachably connected by a locking component.

[0018] The locking holes and locking slots work together to form a mechanical angle-fixing structure. When the sliding component moves to the target angle, the locking component passes through the slot and engages with the corresponding locking hole to achieve physical locking, preventing angular deviation during processing. The multi-hole design provides discrete and reliable fixing points, accommodating rapid positioning for commonly used angles. The detachable connection allows for repeated adjustments, balancing flexibility and stability. This purely mechanical locking solution requires no additional energy, making it particularly suitable for explosion-proof environments or power-constrained scenarios.

[0019] Preferably, it further includes a rotary drive component, the output end of which is fixedly connected to the sliding component.

[0020] A direct connection between the rotary drive and the sliding component enables electric angle adjustment. The output torque of the drive component acts directly on the sliding component, eliminating the impact of transmission backlash on angular accuracy. This design supports programmed control, allowing automatic switching of the bending angle via external commands to meet the continuous operation requirements of automated production lines. The fixed connection method ensures efficient power transmission, reduces response delay, and provides a technical foundation for high-cycle production.

[0021] Preferably, the corner-folding assembly includes a corner-folding frame, a corner-folding module, and a corner-folding drive; the corner-folding frame is fixed on the sliding member; the corner-folding drive is mounted on the corner-folding frame; the corner-folding module is connected to the moving end of the corner-folding drive, the corner-folding frame has a corner-folding platform, and the corner-folding module is configured to move toward the corner-folding platform.

[0022] The modular design of the cornering assembly ensures the structural stability of the processing unit. The cornering frame, acting as a load-bearing base, transmits the cornering force to the sliding component, avoiding localized stress concentration. The linear transmission relationship between the cornering drive and the cornering module provides a vertically downward bending force, and its motion trajectory closely matches the requirements of the battery cell cornering process. This layout optimizes force transmission efficiency, allowing the end execution position of the cornering module to maximize the use of the drive's output force, ensuring the reliability of the cornering action. The cornering platform provides a local support reference surface for the battery cell; when the cornering module is pressed down, the battery cell's corners are constrained between the platform and the module. This double-sided clamping structure helps to disperse the bending force, reducing the risk of deformation of thin-walled battery cells while improving the accuracy of the cornering line position.

[0023] Preferably, the photoelectric sensor is signal-connected to the horizontal drive component and the vertical drive component.

[0024] The photoelectric sensor and the driving component work together to form a closed-loop control system. Displacement data detected by the sensor is fed back to the driving component in real time, allowing the driving component to dynamically adjust its output to eliminate position errors. This structure can suppress positioning deviations caused by mechanical backlash or load variations, improving repeatability. Direct signal connection shortens the response chain, enhancing the system's adaptability to changes in the production environment and ensuring high-precision angle adjustments.

[0025] Furthermore, this utility model also provides a battery production equipment, including the aforementioned angle-adjustable folding device. Because this battery production equipment employs the aforementioned angle-adjustable folding device, it can flexibly adapt to the folding and packaging requirements of battery cells of different specifications, effectively improving the flexibility and production efficiency of the production line.

[0026] The advantages of this utility model compared to the prior art are: This utility model's angle-adjustable bending device solves the problem of bending angle adaptability at a fundamental level by constructing a matching structure between an arc-shaped sliding trajectory surface and a sliding component. 1. Continuous Angle Adjustment Capability: The arc-shaped sliding trajectory surface of the angle adjustment reference component provides a physical guide path for the slider, allowing the angle-folding assembly to move continuously within the arc-shaped trajectory coverage area. Compared to the discrete angle positioning of traditional fixed-angle devices, this structure allows operators to steplessly adjust the angle parameters according to the actual angle requirements of the battery cell. This continuously adjustable characteristic helps reduce the risk of crease misalignment caused by angle deviation, while avoiding frequent mold changes and operational interruptions. The geometric constraint characteristics of the arc-shaped trajectory also prevent the slider from detaching from the reference surface during adjustment, improving the mechanical stability during long-term use.

[0027] 2. Substantial simplification of operation: The direct sliding connection between the slider and the curved trajectory surface eliminates the need for complex transmission mechanisms. During operation, simply pushing the slider changes the spatial angle of the angled assembly, without disassembling parts or using special tools. This "single-action adjustment" mode helps shorten production line changeover time and reduces reliance on operator skill levels. The simplicity of the basic structure also reduces potential points of equipment failure, supporting ease of maintenance.

[0028] 3. Resource savings from versatility design: Because a single device can cover multi-angle processing needs, production lines do not need to configure dedicated angle bending equipment for different cell specifications. This not only reduces equipment procurement costs but also reduces workshop space occupancy. From a manufacturing perspective, the arc-shaped sliding trajectory surface can be formed using standardized machining processes (such as CNC milling), with manufacturing costs comparable to conventional linear guides, but providing greater freedom of movement.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0042] The technical solutions in this application will now be described with reference to the accompanying drawings. Example 1

[0043] This embodiment provides an angle-adjustable bending device, including an angle-adjusting component 1 and a bending component 2; the angle-adjusting component 1 includes an angle-adjusting reference component 11 and a sliding component 12, and the bending component 2 is disposed on the sliding component 12; the sliding component 12 is slidably connected to the reference surface 111 of the angle-adjusting reference component 11, and the reference surface 111 is constructed as an arc-shaped sliding trajectory surface.

[0044] By cooperating with the sliding component 12, the arc-shaped sliding trajectory surface of the angle adjustment reference component 11 forms a continuously adjustable angle adjustment base structure. The free sliding of the sliding component 12 along the arc-shaped trajectory allows the angle adjustment assembly 2 to adapt to any angle requirement, solving the technical defect that traditional fixed angle adjustment devices cannot handle multi-angle processing. Since the arc-shaped trajectory surface provides continuous path guidance, the angle adjustment process of the angle adjustment assembly 2 does not require disassembly or replacement of parts, simplifying the operation process.

[0045] This structural design directly enhances the versatility of the device. The fixed connection between the angle-folding component 2 and the slider 12 ensures the stability of the processing unit during angle adjustment, avoiding deviations in angle-folding accuracy caused by component displacement. The physical constraint characteristics of the arc-shaped trajectory surface prevent the slider 12 from derailing, ensuring mechanical reliability for long-term use. The overall structure achieves basic angle adaptation without relying on a complex control system, reducing manufacturing costs and maintenance difficulty, and providing a universal solution for angle-folding processing of multi-specification battery cells in battery production.

[0046] In this embodiment, the angle adjustment reference member 11 has an angle adjustment scale 112 on its surface perpendicular to the reference plane 111; the slider 12 has a pointer 121, which is aligned with the angle adjustment scale 112.

[0047] The alignment of the angle adjustment scale 112 and the pointer 121 forms an intuitive visual positioning system. Operators can directly read the current angle by observing the real-time position of the pointer 121 on the scale, eliminating the need for experience-based estimation or external measuring tools required in traditional devices. This structure lowers the operational threshold for angle adjustment and reduces the risk of human error. The geometric matching of the scale markings and the curved trajectory surface ensures linear accuracy of the angle indication, enabling even non-professionals to quickly and accurately adjust the angle. The visual assistance system operates without power, enhancing the equipment's applicability in unpowered environments.

[0048] In this embodiment, an adjustment component 3 is also included, which includes a horizontal adjustment component 31 and a vertical adjustment component 32. The horizontal adjustment component 31 is disposed on the moving end of the vertical adjustment component 32. The angle adjustment reference component 11 is fixedly connected to the moving end of the horizontal adjustment component 31.

[0049] The hierarchical structure of adjustment component 3 enables three-dimensional spatial positioning. The vertical adjustment component 32, bearing the horizontal adjustment component 31, forms the initial positioning reference in the vertical direction. The horizontal adjustment component 31 provides secondary translational freedom at its moving end. Finally, the angle adjustment module and the displacement adjustment module are integrated into a unified system through the fixed connection of the angle adjustment reference component 11. This structure enables the angle-bending device not only to adjust the angle but also to compensate for the positional deviation of the battery cell in the fixture. When the processing position of the battery cell changes due to incoming material tolerances or clamping offsets, the adjustment sequence of first lifting and then translating can efficiently correct the coordinates of the angle-bending action point, significantly reducing the dependence on the positioning accuracy of the previous process.

[0050] In this embodiment, the horizontal adjustment member 31 includes a horizontal drive member 311 and a translation block 312; the translation block 312 is connected to the output end of the horizontal drive member 311 and is fixedly connected to the angle adjustment reference member 11.

[0051] The mechanical transmission design of the horizontal drive component 311 and the translation block 312 provides stable linear displacement output. The translation block 312, acting as a power transmission intermediary, converts the output of the drive component into the linear motion of the angle adjustment reference component 11. Its rigid connection characteristics prevent position drift during transmission. This structure is particularly suitable for production line environments requiring high-frequency position fine-tuning. The large contact area of ​​the translation block 312 disperses the motion load, reducing wear on the drive component. The fixed connection ensures that horizontal displacement is transmitted to the angle adjustment module without delay, maintaining consistency in the processing position.

[0052] In this embodiment, the vertical adjustment member 32 includes a vertical drive member 321 and a lifting block 322; the lifting block 322 is connected to the output end of the vertical drive member 321, and the horizontal adjustment member 31 is installed on the lifting block 322.

[0053] The lifting block 322, acting as the execution terminal of the vertical drive component 321, provides a stable lifting platform for the horizontal adjustment module. Its support-type mounting structure forms a rigid whole between the horizontal adjustment component 31 and the lifting block 322, preventing swaying caused by layered installation. When handling battery cells of varying thicknesses, the vertical displacement of the lifting block 322 can quickly match the angle height requirements of the battery cells. This design optimizes the force transmission path; the output force of the vertical drive component 321 acts directly on the load through the lifting block 322, reducing energy loss in intermediate stages and improving the timeliness of the lifting response.

[0054] In this embodiment, the adjustment component 3 is equipped with a photoelectric sensor 33, which is used to detect vertical displacement and horizontal displacement.

[0055] The displacement detection function of photoelectric sensor 33 establishes a position feedback mechanism. By monitoring vertical and horizontal movement in real time, positioning deviations can be detected promptly and compensation actions can be triggered. This non-contact detection avoids mechanical wear and is suitable for high-speed continuous operation environments. Sensor data directly reflects the actual displacement, providing a basis for closed-loop control and helping to improve positioning accuracy. The dual-axis detection capability covers the main motion dimensions of the adjustment component 3, forming a complete displacement monitoring system.

[0056] In this embodiment, the bottom surface of the angle adjustment reference member 11 is provided with a plurality of locking holes 113, and the sliding member 12 is provided with a locking through groove 122. The locking through groove 122 and any locking hole 113 are detachably connected by the locking member 4.

[0057] The locking hole 113 and the locking through slot 122 cooperate to form a mechanical angle fixing structure. When the sliding member 12 moves to the target angle, the locking member 4 passes through the through slot and embeds into the corresponding locking hole 113 to achieve physical locking, preventing angle deviation during processing. The multi-hole design provides discrete and reliable fixing points, adapting to the rapid positioning of commonly used angles. The detachable connection allows for repeated adjustments, balancing flexibility and stability. This purely mechanical locking solution requires no additional energy, making it particularly suitable for explosion-proof environments or power-constrained scenarios.

[0058] In this embodiment, the slider 12 adopts a manual adjustment mode. To achieve angle locking, multiple locking holes 113 are evenly distributed along the arc trajectory on the bottom surface of the angle adjustment reference part 11, and the slider 12 is correspondingly provided with a locking through groove 122. After adjustment, the operator inserts the locking part 4 through the locking through groove 122 and into the target locking hole 113 to form a detachable mechanical fixing structure, ensuring angle stability during angle bending processing.

[0059] In this embodiment, the corner folding assembly 2 includes a corner folding frame 21, a corner folding module 22, and a corner folding drive 23; the corner folding frame 21 is fixed on the sliding member 12; the corner folding drive 23 is mounted on the corner folding frame 21; the corner folding module 22 is connected to the moving end of the corner folding drive 23, the corner folding frame 21 has a corner folding platform 211, and the corner folding module 22 is configured to move in the direction of the corner folding platform 211.

[0060] The modular design of the corner assembly 2 ensures the structural stability of the processing unit. The corner frame 21, acting as a load-bearing base, transmits the cornering force to the sliding member 12, avoiding local stress concentration. The linear transmission relationship between the corner drive member 23 and the corner module 22 provides a vertically downward cornering force, and its motion trajectory is highly compatible with the requirements of the battery cell cornering process. This layout optimizes force transmission efficiency, and the end execution position of the corner module 22 can maximize the use of the drive member's output force, ensuring the reliability of the cornering action. The corner platform 211 provides a local support reference surface for the battery cell. When the corner module 22 is pressed down, the battery cell corners are constrained between the platform and the module. This double-sided clamping structure helps to disperse the cornering force, reduce the deformation risk of thin-walled battery cells, and improve the accuracy of the cornering line position.

[0061] In this embodiment, the photoelectric sensor 33 is signal-connected to the horizontal drive unit 311 and the vertical drive unit 321.

[0062] The photoelectric sensor 33 and the driving component work together to form a closed-loop control system. Displacement data detected by the sensor is fed back to the driving component in real time, allowing the driving component to dynamically adjust its output to eliminate position errors. This structure can suppress positioning deviations caused by mechanical backlash or load variations, improving repeatability. Direct signal connection shortens the response chain, enhancing the system's adaptability to changes in the production environment and ensuring high-precision angle adjustments. Example 2

[0063] This embodiment is an electrification upgrade based on the structure of Embodiment 1: A rotary drive component is added, with its output end rigidly connected to the slider 12, replacing the manual adjustment mode. This drive component directly drives the slider 12 to slide along the arc-shaped trajectory of the reference plane 111, realizing electric angle adjustment.

[0064] Technical advantages: ① Eliminate transmission errors: The direct-drive structure avoids the accumulation of backlash in gear / connecting rod transmissions, improving angular positioning accuracy; ②Automation compatibility: Supports program command-controlled angle switching, adapting to high-speed production line cycle time; ③ Dynamic response optimization: The torque is directly applied to the slider 12, shortening the angle adjustment response time to the millisecond level.

[0065] Note: This embodiment retains the locking hole 113 and locking through groove 122 structure of embodiment 1, but the locking part 4 is only used as a safety redundancy in electric mode.

[0066] Furthermore, this utility model also provides a battery production equipment, including the angle-adjustable folding device described in any of the above embodiments. Because this battery production equipment employs the aforementioned angle-adjustable folding device, it can flexibly adapt to the folding and packaging requirements of battery cells of different specifications, effectively improving the flexibility and production efficiency of the production line.
