Description

Technical Field

[0001] This application relates to the field of battery cover conveying, and in particular to a battery cover conveying device. Background Technology

[0002] In the field of battery cover conveying, existing technologies mainly use fixed-structure conveyor belt lines. This type of design has significant technical drawbacks: the fixed structure can only be adapted to products of a single size. When applied to small-sized products, although compatibility can be achieved by changing the belt, when facing larger-sized products, the replacement cost increases sharply due to the increase in belt size. This not only significantly increases production costs (such as the manpower and material consumption of frequently changing large-sized belts), but also reduces efficiency due to the single adjustment method (only supporting single-sided width adjustment). For example, it cannot simultaneously adapt to battery cover specifications of different lengths and widths, resulting in insufficient production line flexibility. Furthermore, during the adjustment process, uneven force on one side can easily cause belt deviation or wear, affecting the stability of the conveying. Utility Model Content

[0006] A limiting plate is disposed on the surface of the conveying assembly used to convey the battery cover. Along the conveying direction of the conveying assembly, the limiting plates on adjacent conveying assemblies in the transmission group are staggered, and the amount of staggered adjustment of adjacent limiting plates in the transmission group is directly proportional to the amount of movement of the straight rail adjustment assembly, so that the limiting plate can move synchronously with the straight rail adjustment assembly.

[0011] Preferably, the diameter of the limiting hole is in the range of 3-6 mm.

[0012] Preferably, the adjusting member is provided with an oval adjusting hole at the position corresponding to the limiting hole, which extends along the extension direction of the slide rail. The orthographic projection area of ​​the adjusting hole covers at least 3-5 of the limiting holes along the vertical direction perpendicular to the extension direction of the slide rail.

[0013] The adjustment hole is used for fasteners to pass through and connect with the limiting hole. There are multiple fasteners, and there is at least one limiting hole between adjacent fasteners.

[0014] Preferably, the conveying device further includes a wheel track adjustment component, which is disposed on the outer side of the conveying component away from another adjacent conveying component. The wheel track adjustment component and the conveying component are movably connected to adjust the spacing between adjacent transmission groups.

[0015] Preferably, the misalignment adjustment amount of adjacent limiting plates in the transmission assembly relative to the adjustment amount of the wheel track adjustment assembly is within the ratio range of 0.45-0.55.

[0016] Preferably, at least one working surface of the limiting plate used to limit the battery cover is covered with a polyurethane buffer layer, the buffer layer having a thickness of 2-3 mm and a surface roughness Ra≤0.4 μm;

[0017] And / or, the conveying assembly is used to convey the surface of the battery cover plate, which is coated with a composite material of polytetrafluoroethylene and ceramic.

[0018] Preferably, the conveying device further includes an encoder feedback mechanism disposed on the conveying components to detect speed deviations of each of the conveying components and to trigger an automatic compensation program when the speed deviation is greater than 5%.

[0019] And / or, a vibration damper is provided below the transmission component, the vibration damper including a vibration isolation pad and a buffer dual damping structure, so that the natural frequency of the transmission component is less than 15Hz and the resonance amplification factor is not greater than 2.

This not only meets the stringent requirements for conveying vehicle battery cover panels but also significantly improves the compatibility, efficiency, and reliability of the production line.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0031] like Figures 1-5 As shown in the figure, this application discloses a battery cover 200 conveying device 100, which is used to convey the battery cover 200 of a vehicle battery. It is understood that the battery cover 200 of the vehicle battery has characteristics such as heavy weight, delicate surface, and high dimensional accuracy requirements.

[0032] Therefore, the conveying device 100 includes:

[0033] Multiple conveying components 121 are used to convey the battery cover 200. The multiple conveying components 121 are arranged in parallel and driven synchronously. Adjacent conveying components 121 are movably connected and arranged in pairs to form a transmission group 12.

[0034] A straight rail adjustment assembly 13 is disposed on the side of at least one of the transmission groups 12 away from the other transmission group 12, so as to change the spacing between adjacent transmission groups 12 by driving the transmission group 12 to move.

[0035] A limiting plate 14 is disposed on the surface of the conveying assembly 121 for conveying the battery cover 200. Along the conveying direction X of the conveying assembly 121, the limiting plates 14 on adjacent conveying assemblies 121 in the transmission group 12 are staggered, and the amount of staggered adjustment of adjacent limiting plates 14 in the transmission group 12 is directly proportional to the amount of movement of the straight rail adjustment assembly 13, so that the limiting plate 14 can move synchronously with the straight rail adjustment assembly.

[0036] Understandably, given the typically heavy weight of the vehicle battery cover 200, the conveying device 100 requires high load-bearing capacity and stability. Therefore, this application employs a design of "multiple conveying components 121 arranged in parallel and driven synchronously" to ensure uniform force distribution on each conveyor belt, avoiding issues such as uneven loading or deformation caused by excessive force at a single point. Simultaneously, the "paired transmission groups 12" structure enhances overall rigidity, enabling stable support of the heavy battery cover 200, reducing vibration or swaying during transport, and ensuring that the battery cover 200 is not damaged by impact.

[0037] Given the diverse sizes and delicate surfaces of the vehicle battery cover 200, where scratches or collisions are unacceptable, this application utilizes a "straight rail adjustment component 13" to move the transmission assembly 12, achieving precise adjustment of the spacing between adjacent transmission assemblies 12. The limiting plates 14 on adjacent transmission components 121 within the transmission assembly 12 are staggered, and the amount of staggered adjustment is directly proportional to the movement of the straight rail adjustment component 13. This ensures that the limiting plates 14 and the straight rail adjustment component move synchronously, guaranteeing that the battery cover 200 is always precisely limited during spacing adjustments, preventing offset or jamming due to adjustment errors. Furthermore, the flexible movement of the straight rail adjustment component 13 allows for rapid adaptation to battery cover 200s of different lengths without requiring equipment replacement or downtime adjustments, significantly improving the compatibility and efficiency of the production line.

[0038] Because the surface of the vehicle battery cover 200 is typically finely coated or treated, the contact requirements during transportation are extremely high. Therefore, the "offset setting of the limiting plate 14" design in this application ensures that the battery cover 200 only contacts specific parts of the limiting plate 14 during transportation, avoiding surface scratches or wear caused by large-area contact in traditional transportation methods. Simultaneously, the synchronous movement of the limiting plate 14 and the straight rail adjustment assembly ensures that the battery cover 200 is always subjected to a uniform and stable limiting force during adjustment, further reducing the risk of surface damage.

[0039] The production of vehicle battery cover 200 typically requires high efficiency and automation. Therefore, this application achieves synchronous adjustment of the straight rail adjustment component 13 and the limiting plate 14. Since the movement of the straight rail adjustment component 13 and the misalignment adjustment of the limiting plate 14 are directly proportional, the operator only needs to complete the spacing adjustment through a single adjustment action, which greatly shortens the adjustment time, realizes the rapid adaptation of the conveying device 100, and reduces the need for manual intervention.

[0040] Therefore, this application, through technical features such as "synchronous driving of multiple conveying components 121," "straight rail adjustment component 13," and "misaligned setting of limit plate 14," combined with the characteristics of the vehicle battery cover 200—heavy weight, delicate surface, and high dimensional accuracy requirements—achieves multiple technical effects in the conveying device 100, including high stability, high-precision adjustment, surface protection, and high-efficiency automation. This not only meets the stringent requirements for conveying the vehicle battery cover 200 but also significantly improves the compatibility, efficiency, and reliability of the production line.

[0041] like Figures 2-3 As shown, the straight rail adjustment assembly 13 includes a column 131, a slide rail 132, a slider 133, and an adjusting member 134. The slide rail 132 is horizontally arranged along the conveying direction X perpendicular to the conveying assembly 121. The surface of the slide rail 132 is provided with scale markings for spacing adjustment. One end of the column 131 is connected to the conveying assembly 121, and the other end of the column 131 is connected to the slide rail 132 through the slider 133, so that it can move on the slide rail 132. The adjusting member 134 is disposed on the slider 133 and movably connected to the slide rail 132, so as to fix the slider 133 to the target position of the scale markings.

[0042] It is understood that the slide rail 132 is arranged in the horizontal direction and its extension direction is perpendicular to the conveying direction X of the conveying assembly 121.

[0043] Understandably, the slide rail 132 has scale markings on its surface, allowing operators to directly read and adjust the slider 133 to the target position according to the dimensions of the battery cover 200. This avoids errors caused by visual inspection or experience-based judgment, making it suitable for scenarios where the vehicle battery cover 200 has high dimensional accuracy requirements, ensuring that the spacing of the transmission assembly 12 perfectly matches the dimensions of the battery cover 200. Furthermore, the adjusting component 134 fixes the slider 133 to the target position marked on the scale, preventing the slider 133 from shifting due to vibration or external force during transport. This ensures the stability of the spacing between adjacent transmission assemblies 12 and prevents the battery cover 200 from shifting or jamming due to spacing deviations.

[0044] It is understandable that the column 131 is vertically set perpendicular to the extension direction Y of the slide rail 132. The column 131 is connected to the slide rail 132 through the slider 133 and can move quickly in the horizontal direction perpendicular to the conveying direction of the conveying component 121. Compared with the traditional bolt adjustment method, the sliding adjustment does not require repeated disassembly / tightening of bolts. The adjustment can be completed by simply loosening the adjusting part 134, pushing the slider 133 to the target scale and then locking it.

[0045] It is understandable that the movement of the straight rail adjustment component 13 is directly proportional to the misalignment adjustment of the limiting plate 14, ensuring that the limiting plate 14 maintains uniform contact pressure with the edge of the battery cover 200 during spacing adjustment. The surface of the vehicle battery cover 200 is typically treated with high-gloss spraying or electroplating. This synchronous adjustment mechanism avoids excessive local pressure caused by asynchronous adjustment, thus preventing surface scratches or indentations. Furthermore, the sliding engagement between the slider 133 and the slide rail 132 employs a linear guide structure, ensuring a smooth and impact-free adjustment process and guaranteeing the integrity of the battery cover 200.

[0046] In a preferred embodiment, the misalignment adjustment of adjacent limiting plates 14 in the transmission assembly 12 relative to the linear displacement of the column 131 is within the range of 0.45-0.55.

[0047] In a preferred embodiment, the slide rail 132 is provided with a plurality of limiting holes 135 to form the scale markings, and the plurality of limiting holes 135 are arranged at equal intervals along the extension direction Y of the slide rail 132.

[0048] The misalignment adjustment of adjacent limiting plates 14 in the transmission assembly 12 relative to the distance between adjacent limiting holes 135 is within the range of 1.8-2.2.

[0049] Understandably, based on vehicle battery type and its aspect ratio data, such as passenger cars, commercial vehicles, and hybrid models, the aspect ratio is concentrated between 1.8 and 2.2, indicating that the width change and the length change are approximately linearly related. Since the aspect ratio is stable, the width adjustment is usually small, so a small displacement is required to achieve precise adaptation.

[0050] The misalignment adjustment amount of the adjacent limiting plates 14 in the transmission group 12 relative to the linear displacement of the column 131 is designed to be within a ratio range of 0.45-0.55, and the misalignment adjustment amount of the adjacent limiting plates 14 in the transmission group 12 relative to the distance between the adjacent limiting holes 135 is designed to be within a ratio range of 1.8-2.2, which can highly match the linear change trend of the aspect ratio of the battery cover 200.

[0051] In a preferred embodiment, the diameter of the limiting hole 135 is in the range of 3-6 mm.

[0052] like Figure 3 As shown, the adjusting member 134 is provided with an oval adjusting hole 1341 extending along the extension direction Y of the slide rail 132 at the position corresponding to the limiting hole 135. Along the vertical direction perpendicular to the extension direction of the slide rail 132, the orthographic projection area of ​​the adjusting hole 1341 covers at least 3-5 of the limiting holes 135.

[0053] The adjustment hole 1341 is used for fasteners 136 to pass through and connect with the limiting hole 135. There are multiple fasteners 136, and at least one limiting hole 135 is spaced between adjacent fasteners 136.

[0054] It is understandable that the length direction of the oval adjustment hole 1341 is set along the extension direction of the slide rail 132, so that the adjustment part 134 can move continuously within a certain range without strictly aligning with a single limiting hole 135. This achieves a combination of "coarse adjustment + fine adjustment". The operator can first move to the target area quickly, and then use the fastener 136 to accurately position it, avoiding the tedious operation of strictly aligning the traditional round hole, and significantly improving the adjustment efficiency.

[0055] Understandably, the length of the adjustment hole 1341 covers 3-5 limit holes 135, which provides a sufficient adjustment range to adapt to the width changes of the battery cover 200 of different models, while avoiding excessive length that would reduce structural rigidity and affect positioning accuracy.

[0056] like Figures 4-5 As shown, the conveying device 100 also includes a wheel track adjustment component 15, which is disposed on the outer side of the conveying component 121 away from another adjacent conveying component 121. The wheel track adjustment component 15 and the conveying component 121 are movably connected to adjust the spacing between adjacent transmission groups 12.

[0057] In this embodiment, the wheel track adjustment component 15 refers to the adjustment screw. This embodiment includes two transmission groups 12, each containing two pairs of transmission components 121. The four transmission components 121 are arranged in parallel. The two outer transmission components 121 are connected to the transmission shaft of the drive mechanism 16 by the tips of screws. When a large battery cover 200 needs to be transported, adjusting the two outer transmission components loosens the outer screws of the outer transmission components 121 to increase the distance between them and adjacent transmission components 121; or the straight rail adjustment component 13 is directly driven to move, increasing the distance between adjacent transmission groups 12. When a small battery cover 200 needs to be transported, adjusting the two inner transmission components 121 involves rotating the screws along the axial direction of the transmission shaft to loosen the connection between the inner transmission components 121 and the transmission shaft by reducing the deformation of the screw holes, thereby reducing the distance between two adjacent inner transmission components 121.

[0058] Furthermore, the misalignment adjustment amount of adjacent limiting plates 14 in the transmission assembly 12 relative to the adjustment amount of the wheel track adjustment assembly 15 is within a ratio range of 0.45-0.55. The principle is the same as described above and will not be repeated here.

[0059] It is understood that the conveying device 100 includes a controller, which is communicatively connected to the linear guide rail 132 mechanism and the wheel track adjustment component 15 for synchronous and real-time control.

[0060] In a preferred embodiment, the limiting plate 14 has at least one working surface used to limit the battery cover 200 covered with a polyurethane buffer layer, the buffer layer having a thickness of 2-3 mm and a surface roughness Ra≤0.4 μm;

[0061] And / or, the conveying assembly 121 is used to convey that the surface of the battery cover 200 is coated with a composite material of polytetrafluoroethylene and ceramic.

[0062] Based on the core characteristics of the battery cover 200—its delicate and undamage-resistant surface—a polyurethane buffer layer is applied to the working surface of the limiting plate 14, reducing its surface roughness Ra≤0.4μm and lowering the probability of scratches on the battery cover 200. The elastic modulus of polyurethane and the 2-3mm thickness of the buffer layer are optimally matched, facilitating energy absorption during the contact between the battery cover 200 and the limiting plate 14, reducing impact and ensuring the integrity of the battery cover 200. The surface of the battery cover 200 transported by the conveying assembly 121 is coated with a composite of polytetrafluoroethylene and ceramic materials, utilizing its ultra-low coefficient of friction (μ≤0.05) to eliminate transport scratches.

[0063] Therefore, it can be seen that the risk of surface damage to the battery cover 200 during transportation can be minimized by the dual protection design of "soft contact + low friction".

[0064] In a preferred embodiment, the conveying device 100 further includes an encoder feedback mechanism (not shown in the figure), which is disposed on the conveying component 121 to detect the speed deviation of each of the conveying components 121 and to trigger an automatic compensation program when the speed deviation is greater than 5%.

[0065] And / or, a vibration damper (not shown in the figure) is provided below the transmission component 121. The vibration damper includes a dual damping structure of vibration isolation pad and buffer, so that the natural frequency of the transmission component 121 is less than 15Hz and the resonance amplification factor is not greater than 2.

[0066] In this embodiment, the vibration isolation pad is a rubber vibration isolation pad, and the buffer is a hydraulic buffer.

[0067] By employing an encoder feedback mechanism, speed deviations can be monitored in real time, automatically compensated, and synchronized operation ensured. This also prevents battery cover 200 from shifting or being scratched, improving conveying stability. The use of a vibration damper provides a dual-damping structure to suppress vibration, with a natural frequency <15Hz and a resonance amplification factor ≤2. This also protects the surface and structure of the battery cover 200, extending the lifespan of the conveying device 100.

[0068] The foregoing description has fully disclosed the specific embodiments of this application. It should be noted that any modifications made by those skilled in the art to the specific embodiments of this application do not depart from the scope of the claims. Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
