Description

Technical Field

[0001] This utility model relates to the field of sheet material conveying technology, and specifically to an automatic conveying system for sheet material production lines based on intelligent collaborative drive. Background Technology

[0002] In the field of sheet metal processing, such as furniture manufacturing, building decoration, and metal sheet processing, large-sized sheets (such as wood panels, metal sheets, and composite panels) are often transported to designated workstations for operations such as cutting, drilling, and edge banding. To meet the needs of automated production, the precision, automation level, and operational reliability of sheet metal conveying devices are crucial.

[0003] In the field of sheet metal processing, such as furniture manufacturing, building decoration, and metal sheet processing, sheet metal conveying is a fundamental and crucial process. Efficient and precise conveying is a prerequisite for ensuring the quality of subsequent processing such as cutting, edge banding, drilling, and spraying.

[0004] Currently, common sheet metal conveying devices mainly employ fixed conveying mechanisms, such as roller conveyors or belt conveyors. Sheets are placed on the conveyor line, and a drive mechanism moves the rollers or belt, transporting the sheets in a single direction from one workstation to another.

[0005] However, the aforementioned prior art has the following significant drawbacks: For roller conveyor lines, due to the gaps between the rollers, when conveying thin or brittle sheets, the front end of the sheet is prone to breakage or deformation due to uneven force when passing through the gaps between the rollers, which affects product quality.

[0006] While belt conveyors provide a continuous support surface, preventing breakage at the front end of the sheet metal, long conveying distances can lead to belt elongation and loosening due to variations in belt length and tension. This can cause slippage during transmission, preventing the sheet metal from reaching the intended precise position and affecting processing accuracy. Furthermore, belt misalignment can cause the sheet metal to become misaligned on the conveyor line, severely restricting the reliability and processing quality of automated production lines.

[0007] Therefore, there is an urgent need in this field for a new type of sheet material conveying device that can avoid damage to the front end of the sheet material during the conveying process and overcome the slippage and positioning inaccuracy problems caused by long-distance conveying, thereby achieving efficient, stable and accurate conveying of the sheet material. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic conveying system for a sheet metal production line based on intelligent collaborative drive. It can effectively avoid damage during the sheet metal conveying process and solve the problems of slippage and inaccurate positioning caused by long-distance conveying, so as to achieve high-precision and high-efficiency conveying of sheet metal.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automated conveying system for a sheet metal production line based on intelligent collaborative drive includes a base and a conveying mechanism configured on the base for conveying sheet metal; the conveying mechanism includes: The main frame is slidably connected to the base via a sliding connection structure; A conveyor belt assembly, configured to be spaced apart and fixedly connected to the frame body in the transverse direction, for carrying and conveying sheet metal; and An actuating component, which is fixedly connected to the frame body, is used to drive the frame body to perform reciprocating linear motion along the sliding connection structure; The conveyor belt assembly moves in the same direction as the frame body, and the conveyor belt assembly and the frame body move in the same direction to convey the sheet metal.

[0010] Furthermore, the sliding connection structure includes a guide rail fixed to the base and a slider fixed to the frame body and cooperating with the guide rail.

[0011] Furthermore, the guide rails are configured as two spaced-apart rails, and the actuating member is disposed between the two guide rails.

[0012] Furthermore, the conveyor belt assembly includes a drive roller, a driven roller, and a conveyor belt tensioned on both. A rotating shaft is fixedly connected to the frame body in the transverse direction. The drive roller is fixedly connected to the rotating shaft, and the drive rollers of multiple conveyor belt assemblies are driven by the same rotating shaft.

[0013] Furthermore, the drive roller is keyed to the rotating shaft to ensure a stable connection between the drive roller and the rotating shaft.

[0014] Furthermore, the spacing between two adjacent conveyor belt assemblies is adjustable in the lateral direction of the frame body.

[0015] Furthermore, the frame body is equipped with a drive assembly for driving the rotating shaft to rotate. The drive assembly is connected to the rotating shaft via a transmission mechanism. The drive assembly includes a first drive motor, and the transmission mechanism is configured as a belt drive mechanism.

[0016] Furthermore, the actuating component includes a second drive motor fixedly connected to the frame body, a rack is disposed on the base, and a gear meshing with the rack is fixedly connected to the output end of the second drive motor. The second drive motor drives the frame body to move through the meshing of the gear and the rack.

[0017] Furthermore, an electric push rod is disposed on the base, the slider of the electric push rod is fixedly connected to the actuating member, and the driving part of the actuating member is fixedly connected to the frame body, so that the actuating member can drive the frame body to move.

[0018] Furthermore, the base is provided with limiting parts at both ends to restrict the movement of the frame body.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects: This invention solves the core technical problem of positioning inaccuracies caused by long-distance slippage and elongation in traditional belt conveyors by employing a collaborative conveying mechanism that combines the movement of the conveyor belt and the frame body. The conveyor belt handles the initial large-stroke transport, while when final precise positioning is required, an actuating component drives the entire frame body and the plates supported on it to perform precise linear motion. This design prevents the transmission error of the belt from accumulating at the final station; the precise displacement of the frame body directly compensates for the belt's transmission error, thus achieving positioning accuracy far exceeding that of traditional fixed conveyor devices.

[0020] Unlike roller conveyors which have gaps, this invention uses conveyor belt assemblies arranged laterally along the main frame to support the sheet metal, providing a large-area, continuous, and flexible support for the bottom surface of the sheet metal. This completely eliminates the risk of breakage, deformation, or scratches caused by concentrated force on the front end of thin or brittle sheets when crossing the gaps between rollers. It is particularly suitable for conveying materials with high surface quality requirements, such as high-end furniture panels and thin metal sheets, significantly improving conveying quality and product yield.

[0021] This utility model features a compact and rational structural design. By setting two guide rails and placing the actuating component between them, the main frame body is ensured to have balanced force and stable operation. A single rotating shaft synchronously drives the drive rollers of all conveyor belt assemblies, ensuring the synchronicity of the operation of multiple conveyor belts and preventing the sheet metal from deviating. Furthermore, the adjustable spacing between the conveyor belt assemblies allows the device to flexibly adapt to sheet metal of different widths, making it highly versatile. The inclusion of limiting parts ensures operational safety. These design features work together to result in a device with good overall rigidity, reliable operation, and wide applicability.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] Example 1: like Figures 1 to 5 As shown, the automatic conveying system for a sheet metal production line based on intelligent collaborative drive provided by this utility model mainly includes a base 1 and a conveying mechanism. The conveying mechanism is responsible for carrying and conveying the sheet metal.

[0031] The conveying mechanism includes a frame body 2. This frame body 2 is typically constructed from welded or bolted steel sections (such as square steel or channel steel) to form a frame structure with sufficient rigidity and strength to ensure that excessive deformation does not occur during movement and load-bearing. The frame body 2 is slidably connected to the base 1 via a sliding connection structure 3. In this embodiment, the sliding connection structure preferably includes a guide rail 31 and a slider 32. The guide rail 31 is securely bolted to the upper surface of the base 1 and extends along the longitudinal direction of the base 1 (i.e., the direction of plate conveying). The slider 32 is fixedly installed at the bottom of the frame body 2, precisely engaging with the guide rail 31. Preferably, the guide rail 31 and slider 32 employ a high-precision linear guide pair to ensure that the frame body 2 can reciprocate smoothly and with low resistance along a straight line.

[0032] Multiple conveyor belt assemblies 4 are arranged at intervals along the transverse direction (i.e., perpendicular to the conveying direction) on the frame body 2. These conveyor belt assemblies 4 are fixedly connected to the frame body 2 by bolts or other fasteners. Each conveyor belt assembly 4 is used to carry and convey sheet metal. Specifically, each conveyor belt assembly 4 includes a drive roller 41, a driven roller 42, and a conveyor belt 43 tensioned on the drive roller 41 and the driven roller 42. The conveyor belt 43 can be made of rubber, PVC, or polyurethane to provide continuous friction and support. To synchronously drive all conveyor belt assemblies 4, a rotating shaft 44 is fixedly connected to the frame body 2 in the transverse direction via bearing seats. The drive rollers 41 of each conveyor belt assembly 4 are securely connected to this rotating shaft 44 via flat keys. This flat key connection ensures the reliability and stability of power transmission and prevents relative rotation between the drive rollers 41 and the rotating shaft 44. The scheme of using a single rotating shaft 44 to drive all active rollers 41 ensures that the linear speed of all conveyor belts 43 is absolutely synchronized, effectively preventing the problem of the board running off track due to speed asynchrony.

[0033] To drive the rotating shaft 44 to rotate, a drive assembly 5 is disposed on the base 1. This drive assembly 5 includes a first drive motor 51, which is fixed to the base 1. The output shaft of the first drive motor 51 is connected to the rotating shaft 44 via a transmission mechanism 52. In this embodiment, the transmission mechanism 52 is preferably a belt drive mechanism. Specifically, a driving pulley can be installed on the output shaft of the first drive motor 51, and a driven pulley can be installed on the rotating shaft 44, with the two connected by a synchronous belt or a V-belt. Belt drives have the advantages of buffering, vibration absorption, and overload protection. Of course, those skilled in the art can also conceive of using equivalent methods such as chain drives or gear drives.

[0034] The conveying mechanism also includes an actuating component 6. This actuating component 6 is fixedly mounted on the frame body 2 and is used to drive the entire frame body 2 and all its components (including the conveyor belt assembly 4 and the plates) to perform precise reciprocating linear motion along the guide rail 31. In this embodiment, a preferred embodiment of the actuating component 6 includes a second drive motor 61 fixedly connected to the frame body 2. A rack 7 is fixedly mounted longitudinally on the base 1, and a gear 62 that meshes with the rack 7 is fixedly connected to the output shaft of the second drive motor 61. When the second drive motor 61 starts, the gear 62 rolls on the rack 7, thereby pushing the second drive motor 61 and the entire frame body 2 it is fixed to move along the length of the rack 7. Gear and rack transmission has the advantages of high transmission accuracy, large output force, and good rigidity, making it very suitable for precise positioning drive in this solution.

[0035] In another embodiment, the actuating member 6 is configured to be fixedly connected to the slider of the electric actuator, and the actuating member 6 is further fixedly connected to the frame body 2. When the electric actuator is energized, its slider begins to slide, thereby directly pushing or pulling the frame body 2 to perform reciprocating linear motion along the guide rail 31. In this embodiment, the lower end of the actuating member 6 is configured as a U-shaped fixing plate for fixed connection with the slider of the electric actuator, and the upper end is configured to be fixedly connected to the frame body 2 by bolts. Compared with gear and rack transmission, the electric actuator solution has a simpler and more compact structure, may be lower in cost, and has a self-locking function, reliably locking the position when stopped. It is suitable for applications with varying requirements for thrust, speed, and accuracy, providing users with more options.

[0036] To ensure safety, limiters 8 are provided at both ends of the base 1. These limiters 8 can be mechanical stops or inductive limit switches. When the frame body 2 moves to its limit position, the limiters 8 can physically block it or send a signal to force the system to stop, preventing the frame body 2 from derailing and ensuring safe operation.

[0037] Example 2: Based on Example 1, in order to further enhance the adaptability of the device and enable it to stably transport plates of different widths, the installation method of the conveyor belt assembly 4 has been optimized in this example.

[0038] In this embodiment, the spacing between two adjacent conveyor belt assemblies 4 in the transverse direction of the frame body 2 is adjustable. Specifically, this can be achieved by creating elongated mounting holes on the crossbeams of the frame body 2, allowing the flange bolts used to fix the base of the conveyor belt assembly 4 to move and tighten within these holes. The spacing is adjusted in stages by changing the mounting position of the conveyor belt assemblies 4.

[0039] When conveying narrower plates, the conveyor belt assemblies 4 on both sides can be adjusted inwards to provide uniform and sufficient support for the plates, preventing deformation or tilting due to insufficient support points. When conveying wider plates, the conveyor belt assemblies 4 can be adjusted to both sides to ensure that the support range covers the edge of the plates, guaranteeing conveying stability. This design greatly enhances the versatility of this invention.

[0040] In summary, this utility model creatively proposes the concept of "segmented collaborative conveying" by integrating the conveyor belt assembly 4 onto a frame body 2 that can be moved as a whole, perfectly solving the two core problems of "easy damage to the sheet metal" and "inaccurate positioning" in the prior art.

[0041] The continuous support surface provided by conveyor belt 43 completely avoids the risks caused by roller gaps, making it particularly suitable for conveying thin plates, brittle plates, and decorative panels with high surface requirements.

[0042] The dual-guide rail layout ensures the balance of forces and smooth operation of the main frame 2; the single-shaft drive of all active rollers guarantees absolute synchronization of transmission; the adjustable spacing design enhances the flexibility of the equipment; and the setting of the limiting part ensures safety. These features together constitute an efficient, reliable, and highly adaptable plate conveying solution.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
