Description

Technical Field

[0001] This invention relates to the field of roll forming and slitting technology, and in particular to a high-speed roll forming and slitting production line for use in unmanned factories. Background Technology

[0002] Traditional strip processing often requires multiple independent machines to complete unwinding, rolling, slitting, and rewinding operations in steps. This not only results in large equipment footprints but also complex connections between processes, requiring significant manual intervention, leading to low production efficiency and difficulty in ensuring consistent product quality. For example, in lithium battery electrode production, the rolling and slitting devices were previously separate. Battery electrodes had to be rolled on the rolling device, wound, and then transported to the slitting device for cutting. This process was inconvenient and structurally complex, reducing production efficiency. Furthermore, existing rolling and slitting technologies suffered from problems such as poor rolling effect, easy strip breakage during slitting, and burrs on the edges, all of which affected product quality. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to provide a high-speed roll forming and slitting production line that integrates various processes and has high precision and high stability for use in unmanned factories.

[0004] The present invention adopts the following technical solution:

At the same time, it takes into account efficient production, precise control and intelligent management, and has significant technological advancement and economic practicality.

[0037] like Figure 3As shown, a tape-connecting adjustment component 21 is provided on one side of the tape-connecting unit 2. The tape-connecting adjustment component 21 is used to adjust the tension of the tape 7 conveyed by the unwinding unit 1 and to convey the tape 7 to the tape-connecting unit 2. Specifically, the tape-connecting adjustment component 21 can effectively adjust the tension of the tape 7 conveyed by the unwinding unit 1, keeping the tape 7 stable during conveying and avoiding problems such as wrinkles and breakage of the tape 7 caused by uneven tension. This improves the quality and stability of the tape 7 conveying and ensures the smooth progress of subsequent processes. In this embodiment, the tape-connecting adjustment component 21 is a readily available and mature tension adjustment device; its structure and model will not be described in detail.

[0038] like Figure 1 and Figure 2 As shown, a thickness measuring component 8 is provided between the rolling unit 4 and the slitting unit 5. This component 8 is used to detect the thickness of the strip 7 processed by the rolling unit 4 and to transport the detected strip 7 to the slitting unit 5. Specifically, the thickness measuring component 8 allows for real-time detection of the thickness of the strip 7 after processing by the rolling unit 4. Accurate detection of the strip 7 thickness enables timely adjustment of the parameters of the rolling unit 4, ensuring that the strip 7 thickness meets production requirements, improving product quality consistency, and providing the slitting unit 5 with qualified strip 7, reducing slitting defects caused by strip 7 thickness issues.

[0039] like Figure 4 As shown, the slitting unit 5 is internally equipped with a laser thickness measuring module 51 and a burr detection module 52. The laser thickness measuring module 51 is used to detect the thickness of the strip 7 after slitting by the slitting unit 5; the burr detection module 52 is used to detect burrs on the strip 7 after slitting by the slitting unit 5. Specifically, the laser thickness measuring module 51 can detect the thickness of the strip 7 after slitting, further ensuring the thickness accuracy of the product after slitting; the burr detection module 52 can promptly detect burrs on the strip 7 after slitting, facilitating timely removal of burrs, improving the surface quality of the product, avoiding the impact of burrs on the subsequent performance of the product, and reducing the defect rate. In this embodiment, the laser thickness measuring module 51 is an existing mature laser thickness measuring device, and the burr detection module 52 is an existing mature detection camera; the structure and model of both will not be described in detail.

[0040] like Figures 5 to 7As shown, the roller pressing mechanism 42 is connected to the adjustment mechanism 43, and includes a roller pressing group 9 that is driven by the power drive assembly 44. The roller pressing group 9 includes an upper pressure roller 91 and a lower pressure roller 92. The upper pressure roller 91 is arranged parallel to the lower pressure roller 92 directly above it, and the upper pressure roller 91 and the lower pressure roller 92 are respectively driven by the power drive assembly 44 to form a roller pressing structure with corresponding upper and lower parts. Specifically, the upper pressure roller 91 and the lower pressure roller 92 are arranged vertically and horizontally in parallel to form a stable roller pressing structure to ensure uniform force on the material. Both are driven by the power drive assembly 44, and their speeds can be independently adjusted according to the material characteristics, enhancing the adaptability of the equipment to different materials.

[0041] like Figure 6 As shown, both ends of the upper pressure roller 91 are connected to an upper roller shaft 911, and an upper bearing seat 912 is adapted to be installed on the outer side of the upper roller shaft 911; both ends of the lower pressure roller 92 are connected to a lower roller shaft 921, and a lower bearing seat 922 is adapted to be installed on the outer side of the lower roller shaft 921; the upper bearing seat 912 and the lower bearing seat 922 abut against each other in the vertical direction; a support lifting assembly 45 is connected to the bottom of the lower bearing seat 922, and the support lifting assembly 45 is connected to the base 411 in the main frame 41; a plurality of support telescopic assemblies 46 are provided between two adjacent bases 411, and the support telescopic assemblies 46 are used to support the upper pressure roller 91 during the roller disassembly operation. Specifically, the matching installation of the upper roller shaft 911 with the upper bearing seat 912 and the lower roller shaft 921 with the lower bearing seat 922 provides stable support for the roller body and reduces vibration during the rolling process; the upper and lower bearing seats 922 abut in the vertical direction to ensure the parallelism of the roller body and improve the rolling stability; the support lifting assembly 45 connects the lower bearing seat 922 and the base 411, and can flexibly adjust the position of the lower pressure roller 92 to adapt to materials of different thicknesses; the support telescopic assembly 46 supports the upper pressure roller 91 when the roller is disassembled, avoiding deformation of the components during the disassembly process and ensuring maintenance safety.

[0042] like Figure 6 As shown, the supporting lifting assembly 45 is a hydraulic telescopic cylinder. The cylinder body of the hydraulic telescopic cylinder of the supporting lifting assembly 45 is fixedly connected to the base 411, and the end of its piston rod is connected to the bottom of the lower bearing seat 922. The lower bearing seat 922 and the lower pressure roller 92 are lifted as a whole by extending and retracting the piston rod.

[0043] The support telescopic assembly 46 is a hydraulic telescopic cylinder. The cylinder body of the hydraulic telescopic cylinder of the support telescopic assembly 46 is installed between adjacent bases 411. The piston rod end is provided with an arc-shaped support 47. During the roller disassembly operation, the piston rod extends to make the arc-shaped support 47 fit against the roller surface of the upper pressure roller 91 to support the upper pressure roller 91.

[0044] Specifically, the supporting lifting assembly 45 and the supporting telescopic assembly 46 employ hydraulic telescopic cylinders. Hydraulic drive features high output force, precise adjustment, and smooth operation. It can accurately control the lifting and lowering of the lower pressure roller 92 to adjust the roller gap, and also stably support the upper pressure roller 91 through the arc-shaped support 47, meeting the load-bearing and stability requirements of the roller dismantling operation. In this embodiment, the hydraulic telescopic cylinders are all existing mature drive devices, and their structure, model, etc., will not be described in detail.

[0045] like Figure 6 As shown, the power drive assembly 44 includes a drive motor 441, a reducer 442, and a coupling 443 integrated and installed inside the main frame 41. The output shaft of the drive motor 441 is connected to the input end of the reducer 442. The output end of the reducer 442 is connected to the upper roller shaft 911 and / or the lower roller shaft 921 via the coupling 443. The coupling 443 is connected to a support base plate 444, which is fixed inside the main frame 41. Specifically, the drive motor 441, reducer 442, and coupling 443 of the power drive assembly 44 are integrated and installed in the installation chamber, saving space and facilitating centralized maintenance. The drive motor 441 is transmitted to the roller shaft via the reducer 442 and coupling 443, resulting in a clear and efficient power transmission path. The support base plate 444 fixes the coupling 443, reducing radial runout during transmission, ensuring stable power output, and reducing equipment operating noise and component wear. In this embodiment, the power drive assembly 44 includes, but is not limited to, a drive motor 441, a reducer 442, and a coupling 443. In other embodiments, the power drive assembly 44 may also be other existing mature drive devices, the structure and model of which will not be described in detail.

[0046] like Figure 5 As shown, the adjustment mechanism 43 is connected to the axial end of the roller pressing group 9. The roller shape of the roller pressing group 9 is adjusted by the extension and retraction of the adjustment mechanism 43 to eliminate the gap between the rollers. The adjustment mechanism 43 includes a bending cylinder seat 431 and an adjusting bending cylinder 432. The bending cylinder seat 431 is connected to the upper pressure roller 91 and / or the lower pressure roller 92. There are two adjusting bending cylinders 432, which are symmetrically arranged at both ends of the bending cylinder seat 431. The cylinder body end of the adjusting bending cylinder 432 is connected to the bending cylinder seat 431. The piston rod end of the adjusting bending cylinder 432 is movably hinged to a triangular connecting seat 433, which is fixed to the main frame 41. Specifically, the bending cylinder seat 431 of the adjustment component is connected to the roller body, and the two symmetrically arranged adjusting bending cylinders 432 can apply force evenly to ensure uniform roller shape adjustment; the adjusting bending cylinder 432 is hinged to the main frame 41 through the triangular connecting seat 433. The triangular structure enhances the connection stability, reduces shaking during the adjustment process, and improves the roller shape adjustment accuracy and gap elimination effect.

[0047] like Figure 8 As shown, the main frame 41 is used to house the rolling mechanism 42; the feed end of the main frame 41 is connected to a front traction assembly 412, which is used to receive the material conveyed by the calendering unit 3; the discharge end of the main frame 41 is connected to a rear traction assembly 413, which is used to guide the rolled material to the thickness measuring assembly 8; both the front traction assembly 412 and the rear traction assembly 413 are equipped with several guide rollers 414. Specifically, the front traction assembly 412 receives the material from the calendering unit 3, and the rear traction assembly 413 guides the downstream material, realizing the continuity of material conveying and avoiding material accumulation or deviation before and after rolling; the guide rollers 414 guide and tension the material, ensuring that the material enters and leaves the rolling zone in a stable posture, improving the flatness and consistency of the material after rolling. Figure 8 The diagram shows the material traction and movement direction of the device. In this embodiment, the material is stably traction-conveyed through the traction structure and movement direction shown in the diagram. The dimensions and structure of the guide rollers 414 in the traction structure are differentiated, and can be adaptively adjusted according to the specifications of the material. In this embodiment, the material belt 7 is an electrode sheet.

[0048] The working principle of this embodiment is as follows:

[0049] The unwinding unit 1 unwinds the strip 7. After unwinding, the strip 7 is tensioned by the splicing adjustment component 21 and then conveyed to the splicing unit 2. The splicing unit 2 then smoothly conveys the strip 7 to the calendering unit 3 for preliminary processing. Next, the strip 7 output from the calendering unit 3 enters the rolling unit 4. The power drive component 44 drives the upper pressure roller 91 and lower pressure roller 92 of the rolling assembly 9 to rotate, rolling the strip 7. The adjustment mechanism 43 adjusts the roller shape of the rolling assembly 9 by adjusting the extension and retraction of the bending cylinder 432, eliminating the gap between the rollers and making the rolling of the strip 7 more uniform. After rolling, the strip 7 is inspected for thickness by the thickness measuring component 8 and then enters the slitting unit 5. The laser thickness measuring module 51 and the burr detection module 52 inside the slitting unit 5 inspect the slitting strip 7 to ensure slitting quality. Finally, the slitting strip 7 is wound up by the winding unit 6. Throughout the process, the front traction assembly 412 and the rear traction assembly 413 ensure the stability of material conveying through the guide roller 414. The units work together to achieve a high-efficiency and high-quality processing of the material strip 7 from unwinding to rewinding.

[0050] This embodiment achieves fully automated operation of the material strip 7 from unwinding to rewinding by sequentially setting up an unwinding unit 1, a tape receiving unit 2, a calendering unit 3, a rolling unit 4, an adjustment mechanism 43, a power drive assembly 44, a support lifting assembly 45, a support telescopic assembly 46, a front traction assembly 412, a rear traction assembly 413, a thickness measuring assembly 8, a slitting unit 5, and a rewinding unit 6. This greatly improves production efficiency and reduces manual intervention, making it suitable for the production mode of unmanned factories. In an unmanned factory, no human intervention is required for the unwinding, conveying, rolling, slitting, and rewinding of the material strip. The entire process can be autonomously operated through preset programs, reducing errors and safety hazards caused by manual operation. At the same time, it can produce 24 hours a day without interruption, further improving the overall capacity of the factory. The belt tension adjustment component 21 can adjust the tension of the material strip 7 to ensure stable conveying. The roller pressing group 9 works in conjunction with the adjustment mechanism 43 to eliminate gaps between rollers and adjust the roller shape. The support lifting component 45 can adjust the roller gap, and the support telescopic component 46 facilitates roller disassembly and maintenance. The power drive component 44 ensures stable power transmission, and the front traction component 412 and rear traction component 413 ensure smooth material conveying. The thickness measuring component 8 and the laser thickness measuring module 51 of the slitting unit 5 can accurately control the thickness of the material strip 7, and the burr detection module 52 can improve the surface quality of the product. The overall structure is compact and easy to maintain, effectively ensuring the consistency and stability of product quality, meeting different production needs and reducing costs.

[0051] Example 2

[0052] like Figures 9 to 10 As shown, this is an embodiment of the present invention, which relates to a high-speed roll forming and slitting production line for unmanned factories, including an unwinding unit 1, a tape receiving unit 2, a roll forming unit 4a, a slitting unit 5a and a winding unit 6a arranged in sequence.

[0053] The difference from Example 1 is that, as Figure 9 As shown, the rolling unit 4a is composed of a first rolling assembly 41a and a first rolling assembly 42a arranged in sequence. A thickness measuring component 8a for detecting the thickness of the strip 7a after being processed by the first rolling assembly 41a is provided between the first rolling assembly 41a and the first rolling assembly 42a. Downstream of the first rolling assembly 42a, a thickness measuring component 8b for detecting the thickness of the strip 7a after being processed by the first rolling assembly 42a is provided.

[0054] The slitting unit 5a includes a first slitting component 51a, a slitting traction component 52a, and a second slitting component 53a. The first slitting component 51a is responsible for separating the material strip 7a after it has been processed by the first roller pressing component 42a, and slitting a portion of the material strip 7a. The slitting traction component 52a is used to pull another portion of the material strip 7a separated by the first slitting component 51a to the second slitting component 53a, where the second slitting component 53a performs slitting on that portion of the material strip 7a.

[0055] The winding unit 6a is provided with a first winding component 61a and a second winding component 62a. The first winding component 61a is connected downstream of the first slitting component 51a and is used to wind up the material strip 7a after being slitted by the first slitting component 51a. The second winding component 62a is connected downstream of the second slitting component 53a and is used to wind up the material strip 7a after being slitted by the second slitting component 53a.

[0056] The working principle of this embodiment is as follows:

[0057] The strip 7a unwound from the unwinding unit 1 is processed sequentially by the splicing unit 2 and the calendering unit 3 before entering the rolling unit 4a. It undergoes initial rolling by the first rolling assembly 41a, followed by thickness measurement by the thickness measuring assembly 8a. The rolled strip 7a then enters the first rolling assembly 42a for secondary rolling. After secondary rolling, the strip 7a undergoes another thickness measurement by the thickness measuring assembly 8b. The qualified strip 7a enters the slitting unit 5a, where the first slitting assembly 51a separates it and simultaneously cuts a portion of the strip 7a. This cut portion is then wound up by the first winding assembly 61a. The other portion of the strip 7a separated by the first slitting assembly 51a is drawn by the slitting traction assembly 52a to the second slitting assembly 53a, where it is cut and then wound up by the second winding assembly 62a, completing the entire processing flow of the strip 7a.

[0058] In this embodiment, a high-speed roll forming and slitting production line applied to an unmanned factory is used. The roll forming unit 4a adopts a first roll forming component 41a and a first roll forming component 42a arranged in sequence. It can perform secondary roll forming on the material strip 7a to improve the roll forming quality and accuracy of the material strip 7a and meet higher processing requirements. The thickness measuring component 8a between the first roll forming component 41a and the first roll forming component 42a can detect the thickness of the material strip 7a after being processed by the first roll forming component 41a in a timely manner. It is convenient to adjust the parameters of the first roll forming component 42a according to the detection results to ensure the subsequent roll forming effect. The thickness measuring component 8b downstream of the first roll forming component 42a can detect the thickness of the material strip 7a after secondary roll forming again to ensure that the thickness of the material strip 7a entering the slitting unit 5a meets the standard. The slitting unit 5a is equipped with a first slitting component 51a, a slitting traction component 52a, and a second slitting component 53a. The first slitting component 51a can first separate and partially slit the material strip 7a. The slitting traction component 52a can smoothly pull another part of the material strip 7a to the second slitting component 53a for slitting, realizing step-by-step slitting of the material strip 7a, improving the flexibility and accuracy of slitting, and meeting the slitting requirements of material strips 7a of different specifications. The winding unit 6a is equipped with a first winding component 61a and a second winding component 62a, which respectively receive the material strips 7a after being slitted by the first slitting component 51a and the second slitting component 53a, realizing the separate winding of the material strips 7a after slitting, avoiding confusion of the material strips 7a, improving winding efficiency and the convenience of subsequent processing.
