[0002] New energy vehicle battery securing straps are used to secure battery packs. In new energy vehicles, battery packs typically consist of multiple cells. To ensure the safety and stability of the battery pack during vehicle operation, securing straps are required to securely fasten the battery pack to a specific location within the vehicle. These straps are typically constructed from high-strength, corrosion-resistant steel and are protected by insulating material to ensure secure, long-term reliability, and safety. The structural design of the securing straps must take into account the size and shape of the battery pack, as well as the vehicle's structural characteristics, ensuring they can fully enclose and secure the entire battery pack.

This has led to the development of steel strip structures with extruded insulation layers. Existing steel strip production is manually performed, requiring straightening and other processes, resulting in low efficiency and high complexity.

The terms used herein in the specification of this invention are only for the purpose of describing specific embodiments and are not intended to limit this invention. Figures 1 to 7As shown, in one embodiment of the utility model, a fixed-length cutting and forming device for fixing steel strips for new energy batteries is involved, comprising a frame 1, a fixed-length transmission mechanism 2, a cutting mechanism 3 and a forming mechanism 4 arranged in sequence on the frame 1, the fixed-length transmission mechanism 2 is used to transport the steel strip to a fixed length, and the cutting mechanism 3 cuts the steel strip according to the specified length transmitted by the fixed-length transmission mechanism 2; the forming mechanism 4 comprises a forming bracket 41, a clamping transmission component 42, a transmission fixing fixture 43, a bending clamping roller group 44 and a bending drive component 45 arranged in sequence on the forming bracket 41, the clamping transmission component 42 is used to transport the cut steel strip toward the transmission fixing fixture 43, the transmission fixing fixture 43 is used to fix the transmission direction of the steel strip, a heating element 46 is provided in the bending clamping roller group 44 to heat the steel strip during the transmission tightening process, and the bending drive component 45 is used to bend and form the steel strip. This embodiment utilizes automated production, sequentially conveying the steel strip through a fixed-length conveyor mechanism 2. The steel strip is cut to a specified length by a cutting mechanism 3. After cutting, the steel strip is conveyed by a forming mechanism 4, clamped, and bent, achieving automated cutting and forming. This cutting-before-bending process achieves excellent forming results and is suitable for fixed steel strip structures for small-sized packaging. It also facilitates subsequent processing and resolves the complex and inefficient problems of existing steel strip production processes.

[0031] This embodiment significantly improves production efficiency and product precision through integrated design. Its fixed-length transmission mechanism 2 ensures the accuracy of steel strip transportation, effectively avoids material waste, and improves material utilization. The cutting mechanism 3 cooperates with the fixed-length transmission to achieve precise cutting of the steel strip. The forming mechanism 4, as the core part, cleverly integrates the clamping transmission, fixed fixture, heating bending and drive components to form a set of efficient and precise steel strip forming solutions. The coordinated work of the clamping transmission component 42 and the transmission fixed fixture 43 not only ensures the stability of steel strip transmission, but also ensures the accurate positioning of the steel strip before bending. The heating element 46 integrated in the bending clamping roller group 44 optimizes the bending performance of the steel strip through timely heating, reduces stress concentration during the bending process, and improves the bending quality of the product. The precise control of the bending drive component 45 realizes the precise bending and forming of the steel strip, meeting the strict requirements of high precision and high quality for the fixed steel strip of new energy batteries. This embodiment greatly improves production efficiency and product quality, has significant technical effects and broad application prospects.

[0032] See Figure 4As shown, the fixed-length conveying mechanism 2 includes a fixed-length support 21, a fixed-length guide roller 22, a fixed-length measuring motor 23, and a fixed-length connecting roller 24. The fixed-length support 21 is mounted on the frame 1, the fixed-length guide roller 22 is mounted on the fixed-length support 21, and the fixed-length measuring motor 23 is mounted below the fixed-length support 21. One end of the fixed-length connecting roller 24 is connected to the drive end of the fixed-length measuring motor 23, which is used to drive the fixed-length connecting roller 24 in rotation. Specifically, the fixed-length measuring motor 23 is equipped with an encoder (not shown) that detects shaft rotation and converts the angle information into an electrical signal. This information is then used to determine the conveyed length of the steel strip based on the rotation angle. In this embodiment, the precise coordination of the fixed-length support 21, guide roller, measuring motor, and connecting roller enables precise control of the conveyed length of the steel strip. The encoder (not shown) of the fixed-length measuring motor 23 provides real-time feedback on the shaft rotation angle, which is accurately converted into an electrical signal representing the conveyed length of the steel strip. This ensures strict consistency in the length of each steel strip segment, meeting the stringent material precision requirements of new energy battery manufacturing. This design not only improves the automation level of the production line, but also significantly enhances the stability of product quality and production efficiency, providing strong support for the high-quality development of the new energy battery industry.

[0033] See Figure 5 As shown, the cutting mechanism 3 includes a cutting bracket 31, a cutting drive motor 32, a cutting drive element 33 connected to the cutting drive motor 32, and a cutting shear 34 connected to the cutting drive element 33. The cutting bracket 31 is arranged at the rear side of the fixed-length conveying mechanism 2. The cutting drive motor 32 is used to drive the cutting drive element 33 toward the steel strip delivery position. Specifically, the cutting drive element 33 is a hydraulic cylinder that drives the cutting shear 34 to cut the steel strip. In this embodiment, the stable support of the cutting bracket 31 and the powerful driving force of the cutting drive motor 32 are integrated to drive the cutting shear 34 toward the steel strip. The combination of the hydraulic cylinder as the cutting drive element 33 ensures smooth and reliable cutting. The precise control of the hydraulic cylinder enables the cutting shear 34 to accurately act on the steel strip, achieving efficient cutting and meeting the precise requirements of new energy batteries for a fixed steel strip length. This structure not only improves production efficiency but also ensures the quality consistency of steel strip cutting, providing a solid guarantee for the stability and safety of new energy batteries.

[0034] See Figure 6 As shown, the clamping and transmission assembly 42 includes multiple clamping and transmission rollers 421, positioned vertically and oppositely, for conveying the steel strip. In this embodiment, these multiple clamping and transmission rollers 421 precisely and stably clamp and convey the steel strip, ensuring that the strip's position remains stable on high-speed production lines and effectively preventing misalignment and wrinkling during the production process. This structure not only improves the smoothness and accuracy of steel strip transmission, but also enhances the smoothness and accuracy of steel strip transmission.

[0035] The transmission fixing jig 43 includes a horizontal fixed wheel 431 and a vertical fixed wheel 432. The horizontal fixed wheel 431 and the vertical fixed wheel 432 are each provided with a plurality of them and are used to fix and guide the steel strip in the vertical and horizontal directions respectively. Specifically, the horizontal fixed wheel 431 is provided with a horizontal fixed groove 4311, and the vertical fixed wheel 432 is provided with a vertical fixed groove 4321, which are used to position the direction of the steel strip during transmission. In this embodiment, the integrated transmission fixing jig 43 of the horizontal fixed wheel 431 and the vertical fixed wheel 432 significantly improves the stability and directional accuracy of the steel strip transmission. The horizontal fixed groove 4311 on the horizontal fixed wheel 431 and the vertical fixed groove 4321 on the vertical fixed wheel 432 are closely matched to ensure that the steel strip is accurately guided and firmly fixed in both the vertical and horizontal directions, effectively avoiding deviation and jitter during transmission, and ensuring the continuity and quality consistency of steel strip preparation.

[0036] See Figure 7 As shown, the bending clamping roller group 44 includes a fixed clamping roller 441, a movable clamping roller 442, and a clamping drive module 443. The clamping drive module 443 is used to drive the movable clamping roller 442 to move relative to the fixed clamping roller 441 to clamp and transmit the steel strip during transmission. The heating element 46 is provided on the fixed clamping roller 441 and the movable clamping roller 442. Specifically, the bending drive assembly 45 includes a bending bracket 451, a bending motor 452, and a bending clamping shaft 453. The bending bracket 451 is provided on one side of the bending clamping roller group 44, the bending motor 452 is provided on the bending bracket 451, the bending clamping shaft 453 is provided at the driving end of the bending motor 452, and the bending clamping shaft 453 is provided with a bending clamping groove 4531, one end of which faces between the fixed clamping roller 441 and the movable clamping roller 442. In this embodiment, through the precise control of the clamping drive module 443, the movable clamping roller 442 and the fixed clamping roller 441 work closely together to ensure that the steel strip is stably clamped during transmission, effectively avoiding positional offset and deformation, and improving the processing accuracy and yield rate of the steel strip. At the same time, the clever arrangement of the heating element 46 achieves uniform heating treatment of the steel strip, optimizes the physical properties of the material, and lays a solid foundation for the subsequent bending process. The bending drive assembly 45 drives the bending clamp shaft 453 in an efficient and stable manner, using the bending clamp groove 4531 to accurately clamp the steel strip and guide it to bend at a preset angle, ensuring the precise forming of the new energy battery fixing steel strip and meeting the high-standard production process requirements.
