Description

Technical Field

[0001] This utility model belongs to the field of battery pack assembly technology, specifically relating to a battery pack assembly and riveting device. Background Technology

[0002] With the increasing number of cars on the global road, the environment faces enormous challenges. Traditional gasoline-powered vehicles emit large amounts of exhaust fumes and particulate matter, causing serious pollution to air and water. In particular, carbon dioxide emissions are a major cause of global warming. The development of new energy vehicles is a crucial measure to address global climate change and environmental pollution. New energy vehicles use clean energy as their power source, reducing dependence on traditional energy sources such as oil, effectively lowering exhaust emissions and greenhouse gas emissions, significantly improving air quality, and reducing environmental impact. Therefore, the development and promotion of new energy vehicles are particularly important. Simultaneously, with the increasingly severe global energy security situation, new energy vehicles also play a vital role in ensuring energy supply. Traditional gasoline-powered vehicles rely heavily on imported oil; therefore, fluctuations in oil prices and supply instability have a significant impact on economic development and national security. New energy vehicles, powered by clean energy sources such as electricity and hydrogen, not only reduce dependence on oil but also utilize domestic renewable energy sources, increasing the stability and sustainability of energy supply.

[0003] For the development of new energy vehicles, the core component, the battery pack, is the most crucial, as it is the sole power source. Therefore, battery pack production technology is paramount, encompassing quality control during cell assembly, overall pack testing, and final cover installation. The cover installation process, in particular, demands stringent requirements, as it directly impacts the overall sealing and internal environmental stability of the battery pack. Current installation methods typically involve manual assembly and riveting, which is further limited by existing equipment structures. This not only fails to guarantee a perfect fit between the cover and the lower casing but also results in inconsistent manual processes, ultimately affecting product yield. Furthermore, current equipment struggles to accommodate the specifications of new products. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-3 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0022] This invention discloses a battery pack assembly riveting device, used for riveting connections between the casing and the top cover during the battery pack assembly process. This is mainly achieved through a top cover clamping device and a riveting device located on one side of the top cover clamping device. The top cover clamping device is positioned above the battery pack support mechanism to clamp the top cover, and the riveting device is used to rivet the clamped product at the required positions.

[0023] Furthermore, existing clamping mechanisms can easily lead to incomplete fit between the top cover and the housing, potentially causing displacement and affecting the riveting effect. The top cover clamping device of this invention includes a frame 1 and a transfer assembly mounted on the frame 1. A lifting assembly is mounted on the transfer assembly via a connecting plate 6. The lifting assembly is connected to a clamping assembly located below the transfer assembly. A clamping assembly is also provided between the connecting plate, the transfer assembly, and the clamping assembly.

[0024] In this embodiment, the transfer assembly includes a transfer slide rail mounted on a frame 1 and transfer rods 2 mounted on the transfer slide rail via a slider. A transfer cylinder 12 is provided on one side of the transfer slide rail, and the transfer cylinder 12 drives the slider to move the transfer rods back and forth on the transfer slide rail. A set of transfer rods 2 is provided, and the two transfer rods achieve reciprocating motion in opposite directions under the operation of the transfer cylinder 12.

[0025] The lifting assembly includes a main lifting cylinder 31 and auxiliary lifting cylinders 32 disposed on both sides of the main lifting cylinder 31. The main lifting cylinder 31 is used to perform the main clamping action on the clamping assembly. In this device, the clamping assembly itself is relatively heavy, and it will generate a corresponding reaction force during clamping. In order to better balance the force, when the main lifting cylinder 31 is clamping, the auxiliary lifting cylinder 32 will adopt the opposite action of the main lifting cylinder 31, that is, to pull the clamping assembly upward.

[0026] The lifting assembly is fixed to the connecting plate 6, and lifting guide rods 33 are also provided on both sides of the lifting assembly. A set of slide rails 61 is fixed to the bottom of the connecting plate 6. The bottom of the slide rails 61 is connected to the transfer rod 2 via sliding blocks 62. The transfer rod 2 reciprocates on the slide rails 61 via the sliding blocks 62, which is used to cooperate with the riveting equipment to make necessary positional avoidance during the riveting operation.

[0027] The clamping assembly includes a clamping plate 4 disposed below the transfer rod 2, and clamping blocks 41 are evenly distributed around the periphery of the clamping plate 4. An elastic element is provided between the clamping blocks 41 and the clamping plate 4; in this embodiment, the elastic element is a spring. The distributed clamping blocks 41 combined with springs can better clamp the product, avoiding the misfitting of the product caused by uneven force during clamping when using a one-piece clamping rod.

[0028] The clamping assembly includes a cylinder 5 mounted on the connecting plate 4. The cylinder shaft of the cylinder 5 is connected to a clamping block 51 mounted on the transfer rod 2. A second connecting assembly 53 is also provided between the outer side of the transfer rod 2 and the pressure plate 4. When the cylinder 5 operates, the relative positions of the connecting plate 6, the pressure plate 4, and the transfer rod 2 can be fixed. The reason for this arrangement is that this device is used to clamp the product cover to the box body. Both the clamping assembly and the lifting assembly are connected to the connecting plate. When the lifting assembly performs the clamping action, the pressure plate, the transfer rod, and the connecting plate maintain a balance between the applied force and the reaction force, thus maintaining the fixed relative positions. However, when the lifting assembly is not in operation, that is, when the connecting plate 6, the pressure plate 4, and the transfer rod 2 are not under force, since the transfer rod 2 and the connecting plate 6 are connected by a slide rail, only the connecting plate 6 is subjected to the force of the pressure plate 4's own weight, which can easily cause the connecting plate to slide in the slide rail position. This causes the pressure plate 4 to shift accordingly, resulting in a change in the reference when pressing the product. Ultimately, the pressure block 41 on the pressure plate 4 cannot accurately press the product to the required position. Therefore, it is necessary to keep the relative positions of the pressure plate, the connecting plate, and the transfer rod fixed at this time. This purpose can be achieved by using the clamping assemblies on both sides.

[0029] The riveting device of this invention includes a six-axis robotic arm 7 and a riveting assembly disposed at the operating end of the six-axis robotic arm 7. The riveting assembly includes a riveting gun 71 and an adsorption assembly disposed on one side of the riveting gun 71. The adsorption assembly is connected to a collection hopper 72 via a pipe. When riveting is performed, the waste generated will be directly adsorbed and collected into the collection hopper 72 by the adsorption assembly.

[0031] Furthermore, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although this 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 of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
