Description

Technical Field

[0001] This utility model relates to the field of automotive parts conveying devices, and in particular to a conveying device in a new energy vehicle parts production line. Background Technology

[0002] Suspended conveyor systems are widely used aerial transport systems in new energy vehicle production lines, primarily for the painting, drying, and final assembly processes of irregular parts such as car bodies and battery packs. They suspend workpieces in the air via tracks and hangers, using chains or electric drives for continuous transport. This saves ground space and avoids interference with other process equipment. The system is suitable for multi-station workflows, especially for contactless transport of lightweight materials or precision components, but it relies on a high-precision track layout and dynamic balance control system.

[0003] Current overhead conveyor systems exhibit significant shortcomings when dealing with irregular structures and weight distributions of new energy vehicle components, such as irregularly shaped battery boxes and multi-curved body surfaces. Dynamic balance control of the lifting device is particularly critical: due to the complex shapes of the components and frequent shifts in the center of gravity, if the load is overloaded or unevenly distributed, the lifting device is prone to longitudinal shift in the vertical direction of movement during high-speed operation. This can lead to inaccurate positioning at painting or assembly stations, and even pose a risk of collision between the workpiece and the robotic arm. Simultaneously, the rigid transmission characteristics of the conveyor chain can cause lateral swaying along the direction of movement. Especially during track turns or sudden stops, inertia causes the lifting device to swing back and forth, exacerbating uneven spray atomization or sealant misalignment. More seriously, the lateral swaying of the lifting device can couple with the longitudinal shift, accumulating errors over long distances and ultimately requiring frequent shutdowns for manual calibration, severely slowing down the production line.

[0004] Therefore, this application provides a conveying device in a new energy vehicle parts production line to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a conveying device in a new energy vehicle parts production line, which solves the problems of existing suspended conveying devices having high dynamic balance requirements, easy lateral and longitudinal swaying of the lifting device when the load is uneven, resulting in positioning deviation, and the need for frequent calibration due to vibration accumulation.

[0006] To solve the above-mentioned technical problems, this utility model provides a conveying device in a new energy vehicle parts production line, including an I-shaped slide rail, with first slide rails on both sides of the slide rail, and two second slide rails extending parallel to the conveying direction on the bottom surface of the slide rail.

[0007] Multiple lifting device assemblies are movably installed on the first slide rail. All lifting device assemblies are locked by a fixed chain. Each lifting device assembly includes a first roller respectively installed on the first slide rail. A support frame is installed on the outer side of the first roller. Two support frames extend downward and cover both sides of the bottom surface of the slide rail. Each support frame is symmetrically provided with an upwardly inclined support arm. A second roller adapted to the second slide rail is installed at the end of the support arm. The second roller is embedded in the second slide rail to limit the lateral and longitudinal swaying of the lifting device.

[0008] A further improvement of this utility model is that: the edge of the support frame is provided with an outwardly protruding stop, and a chain groove is opened on the bottom stop of the support frame.

[0009] A further improvement of this utility model is that a fixed chain is installed in the chain groove, the fixed chain connects all the lifting equipment components into one unit, and a traction machine is set at the front end of the fixed chain.

[0010] A further improvement of this utility model is that a suspension plate is provided between the interlayers of two adjacent support frames, the suspension plate protrudes downward from the bottom of the support frame, and multiple through locking holes are opened on the overlapping part of the support frame and the suspension plate. Locking bolts are provided in the locking holes, and the locking bolts are used to lock the support frame and the suspension plate.

[0011] A further improvement of this utility model is that at least two locking holes are provided.

[0012] A further improvement of this utility model is that a suspension hole is provided on the part of the suspension plate that protrudes downward from the support frame.

[0013] A further improvement of this utility model is that: the two second slides are arranged relatively parallel to each other, the depth of the two second slides is 2 to 3 cm, and the vertical distance between the two second slides is ≥ 5 cm.

[0014] A further improvement of this utility model is that the support arms on the same support frame extend along the conveying direction, and the included angle between the two support arms is ≥120°.

[0015] A further improvement of this utility model is that the surfaces of the first roller and the second roller are covered with a polyurethane damping layer.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides a conveying device in a new energy vehicle parts production line. This conveying device is beneficial for multi-dimensional anti-deviation. Two parallel second slides are set on the bottom surface of the I-shaped slide rail. The second roller at the end of the support arm is embedded in the slide. The bidirectional limiting effect of the second roller and the slide effectively suppresses the lateral and longitudinal sway of the lifting device, and solves the problem of spraying deviation or assembly error caused by inertial swing of traditional lifting devices.

[0018] 2. The present invention provides a conveying device in a new energy vehicle parts production line. The symmetrical design of the support arm of the conveying device with an included angle of ≥120°, combined with the layout of the second slide rail with a vertical spacing of ≥5cm, forms a stable triangular support structure, which improves the adaptability of the lifting device to the center of gravity shift of irregular parts and reduces the risk of longitudinal shift caused by uneven load.

[0019] 3. The present invention provides a conveying device in a new energy vehicle parts production line. This conveying device is beneficial for suppressing vibration and enhancing stability. The surfaces of the first roller and the second roller are covered with a polyurethane damping layer to absorb the vibration energy generated by the rigid transmission of the fixed chain, avoid the vibration from being transmitted and amplified along the track, and reduce the cumulative impact of coupled vibration on positioning accuracy. The suspension plate and the support frame are rigidly connected by locking bolts, which enhances the overall structural rigidity of the lifting device assembly, prevents high-frequency shaking from causing the connecting parts to loosen, and reduces the frequency of downtime for calibration.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The present invention will be further explained below with reference to specific embodiments.

[0033] like Figures 1-7As shown in the figure, the conveying device in the production line of new energy vehicle parts provided in this embodiment includes an I-shaped slide rail 1. First slide rails 11 are opened on both sides of the slide rail 1. Two second slide rails 12 extending parallel to each other along the conveying direction are opened on the bottom surface of the slide rail 1. The two second slide rails 12 are arranged relatively parallel to each other to form a bidirectional limiting channel. The depth of the two second slide rails 12 is 2 to 3 cm, and the vertical distance between the two second slide rails 12 is ≥ 5 cm.

[0034] like Figures 1-7 As shown, in this embodiment, multiple lifting device assemblies 2 are movably arranged on the first slide rail 11. All lifting device assemblies 2 are locked by a fixed chain 3. Each lifting device assembly 2 includes a first roller 21 respectively arranged on the first slide rail 11. A support frame 22 is arranged on the outer side of the first roller 21. The two support frames 22 extend downward and cover both sides of the bottom surface of the slide rail 1. Each support frame 22 is symmetrically arranged with an upwardly inclined support arm 24. The end of the support arm 24 is provided with a second roller 23 adapted to the second slide rail 12. The second roller 23 is embedded in the second slide rail 12 to limit the lateral and longitudinal sway of the lifting device. The embedded cooperation between the second slide rail 12 and the second roller 23 simultaneously restricts the degree of freedom of the lifting device in both the lateral and longitudinal directions, reducing the offset amplitude by more than 40%. The support arm 24 on the same support frame 22 extends along the conveying direction, and the included angle between the two support arms 24 is ≥120°. This conveying device facilitates multi-dimensional anti-deviation. Two parallel second slide rails 12 are set on the bottom surface of the I-shaped slide rail 1, and the second rollers 23 at the ends of the support arm 24 are embedded in the slide rails. The bidirectional limiting effect of the second rollers 23 and the slide rails effectively suppresses lateral and longitudinal swaying of the lifting device, solving the problem of spraying deviation or assembly errors caused by inertial swaying in traditional lifting devices. The symmetrical design of the support arm 24 with an included angle ≥120°, combined with the layout of the second slide rails 12 with a vertical spacing ≥5cm, forms a stable triangular support structure. This triangular support structure adapts to center of gravity shifts. Through the rolling of the second rollers 23 within the slide rails, it compensates in real time for longitudinal deviations caused by uneven loads, controlling the positioning error within ±1.5mm. This improves the lifting device's adaptability to center of gravity shifts of irregularly shaped parts and reduces the risk of longitudinal deviations caused by uneven loads.

[0035] like Figures 2-7As shown, in this embodiment, the support frame 22 has outwardly protruding flanges 25 on its edges, and chain grooves 31 are formed on the bottom flanges 25 of the support frame 22. Fixed chains 3 are installed in the chain grooves 31, connecting all lifting assemblies 2 into one unit. A traction machine is installed at the front end of the fixed chain 3; the traction machine is an existing product. Suspension plates 26 are provided between the layers of two adjacent support frames 22, protruding downwards from the bottom of the support frame 22. Multiple through-holes 28 are formed on the overlapping portions of the support frame 22 and the suspension plates 26, with at least two locking holes 28. Locking bolts 29 are installed within the locking holes 28 to lock the support frame 22 and the suspension plates 26. Suspension holes 27 are formed on the downward-protruding portion of the suspension plates 26, used to connect workpieces. The fixed chain 3 and the lifting assemblies 2 form a closed traction system, preventing lubricating grease from splashing and contaminating sensitive areas such as the battery casing, while also reducing the risk of the fixed chain 3 derailing.

[0036] like Figure 4 As shown, in this embodiment, the surfaces of the first roller 21 and the second roller 23 are covered with a polyurethane damping layer. This absorbs the vibration energy generated by the rigid transmission of the fixed chain 3, prevents vibration from being transmitted and amplified along the track, and reduces the cumulative impact of coupled vibration on positioning accuracy. The suspension plate 26 is rigidly connected to the support frame 22 by locking bolts 29, which enhances the overall structural rigidity of the lifting device assembly 2, prevents high-frequency shaking from causing the connecting parts to loosen, and reduces the frequency of downtime for calibration.

[0037] This utility model also provides the operating principle of a conveying device in a new energy vehicle parts production line:

[0038] When using the conveyor device in this new energy vehicle parts production line, the slide rail 1 is first fixed to the top of the production line. The first slide rails 11 on both sides provide rolling support for the first rollers 21 of the lifting assembly 2, while the second slide rail 12 at the bottom achieves bidirectional limiting through the insertion of the second rollers 23 at the end of the lifting support arm 24. The workpiece is fixed to the bottom of the lifting device by the suspension plate 26 and the locking bolts 29. After the workpiece is connected to the suspension hole 27, the fixed chain 3 is driven by the traction machine to move at a constant speed along the slide rail 1. The fixed chain 3 drives all the lifting assemblies 2 to move synchronously. The second rollers 23 slide in the second slide rail 12 to suppress lateral swaying, and the triangular structure of the support arm 24 adaptively adjusts the center of gravity offset to prevent longitudinal offset. When transported to the spraying station, the stability of the lifting device ensures the uniformity of spraying, and the polyurethane rollers absorb vibration energy to reduce error transmission. After completing the process, the lifting device continues to move to the next station. During the cycle operation, the suspension plate 26 can be quickly replaced to adapt to different specifications of parts. During maintenance, only the lubrication of the fixed chain 3 and the wear condition of the first roller 21 and the second roller 23 need to be checked, so as to achieve efficient and high-precision continuous conveying.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
