Description

Technical Field

[0001] This invention relates to the field of automotive equipment manufacturing technology, and in particular to a flexible loading and unloading device for battery trays of multi-model automobiles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, battery trays, as an important component for supporting and protecting power battery systems, are facing increasingly stringent requirements in terms of production scale and quality. Existing battery tray production lines have significant bottlenecks in terms of production efficiency and flexibility. To meet the urgent demands of vehicle manufacturing for higher production efficiency and flexibility, the level of automation and intelligence in battery tray production lines has become a crucial indicator of industry competitiveness.

[0003] Currently, existing battery tray production lines still face significant bottlenecks in their loading and unloading processes. Most existing battery tray loading and unloading methods employ dedicated positioning and handling devices designed for single vehicle models. While these achieve initial automation, they lack sufficient flexibility. When the production line needs to switch to producing battery trays of different models, sizes, or positioning structures, the existing loading and unloading methods are often incompatible, requiring downtime and manual disassembly, replacement, and recalibration. This not only increases non-value-adding time and lengthens production cycles but also reduces equipment utilization and introduces the risk of human error, thereby increasing labor and equipment modification costs.

[0004] Furthermore, existing battery tray loading and unloading production methods typically employ a serial operation approach, meaning that the loading and unloading processes are independent and executed sequentially. Specifically, a new battery tray can only begin loading after the previous one has been completely unloaded. This "wait-and-carry" model results in equipment idleness and periodic efficiency losses, limiting further increases in production cycle time and becoming a key obstacle to improving overall line capacity, making it difficult to meet actual application needs.

[0033] Due to the adoption of the above structure, the present invention has the following beneficial effects:

[0034] In this invention, a flexible loading and unloading device for battery trays of multiple car models is pre-connected to an external control cabinet. Through the cooperation of the first sliding device and the first positioning device, the second sliding device and the second positioning device, and the third sliding device and the third positioning device, positioning parameters for battery trays of at least three car models can be pre-set and stored. When the production line needs to switch car models, the corresponding program is called through the control cabinet to control the first sliding device, the second sliding device, or the third sliding device to work with the corresponding first positioning device, the second positioning device, or the third positioning device. This moves the required first positioning device, the second positioning device, or the third positioning device to the working position, thus achieving rapid and automatic car model switching. This enables efficient parallel and seamless switching of loading and unloading operations for battery trays of different car models without any manual disassembly or mechanical adjustment. It fundamentally solves the problem of insufficient flexibility of traditional single tooling and significantly improves the response speed and equipment utilization of the production line.

[0035] In this invention, the independent control of the first, second, and third sliding devices enables physical separation and collaborative operation of the loading and unloading stations. While one battery tray is being unloaded, the loading of another vehicle model or a tray of the same model can be performed simultaneously, breaking the "waiting" bottleneck of the traditional model. This synchronous flexible production mechanism achieves seamless connection between loading and unloading actions, greatly reducing non-productive auxiliary time, thereby significantly shortening the overall production cycle and increasing production line capacity.

[0036] In this invention, the coordinated operation of the first sliding device and the first positioning device, the second sliding device and the second positioning device, and the third sliding device and the third positioning device achieves fully automated operation, completely replacing manual labor. This fundamentally eliminates personal safety risks and human error, ensuring the consistency and stability of product quality. Simultaneously, rapid automatic production switching reduces reliance on professional personnel and associated time and training costs, while avoiding equipment wear and production interruptions caused by frequent tooling changes, thus achieving multiple benefits in safety, quality, and cost.

[0037] This invention employs a modular integrated design, consisting of a first sliding device and a first positioning device, a second sliding device and a second positioning device, and a third sliding device and a third positioning device. The overall structure is compact, saving production line space. Furthermore, by replacing the corresponding positioning and detection components, it can adapt to more vehicle models, significantly reducing the difficulty and cost of later modifications, and providing a solid foundation for the construction of intelligent unmanned workshops.

[0038] Therefore, the present invention has the advantages of being able to adapt to the battery tray loading and unloading operations of various vehicle models, efficiently and in parallel with seamless switching to improve production cycle time, and effectively improve equipment utilization to reduce labor and equipment modification costs.

[0086] Please refer to Figures 9 to 10 As shown, the high-cycle loading and unloading mode for a single vehicle model:

[0087] S1. Initial State: The first positioning device 400 is located at the leftmost loading position, on which the battery tray 100 is placed. Both the first left sensor 202 and the first sensor 403 detect the presence of the battery tray 100.

[0088] S2. First Position Switching of Positioning Devices: The unloading robot removes the battery tray 100 from the second positioning device 600, and the second sensor 603 detects that the battery tray 100 is not present. The second sliding device 500 moves the second positioning device 600 to the leftmost position, and the second right sensor 205 detects that the battery tray 100 is not present. Simultaneously, the first sliding device 300 moves the first positioning device 400 and the battery tray 100 to the rightmost position, and the first left sensor 202 detects that the battery tray 100 is not present. At this time, the first positioning device 400 is in the unloading position, and the second positioning device 600 is in the loading position, completing the first positioning device position switching. The current state is as follows: Figure 10 As shown.

[0089] S3.

The loading robot then loads the second vehicle model battery tray 100 onto the second positioning device 600. At this time, the state is as follows. Figure 14 As shown, this reciprocating motion completes the loading and unloading of the second vehicle model's battery tray 100.

[0095] S3, Third Vehicle Model Loading / Unloading Mode: Initially, the third positioning device 800 is located at the leftmost end, and the loading robot completes the loading. At this time, the first positioning device 400 and the second positioning device 600 are both at the rightmost end. The third sliding device 700 drives the third positioning device 800 to slide to the rightmost end, while the first sliding device 300 and the second sliding device 500 respectively drive the first positioning device 400 and the second positioning device 600 to slide to the leftmost end. The state at this time is as follows. Figure 15 As shown; then the unloading robot removes the third vehicle model battery tray 100, the third sliding device 700 drives the third positioning device 800 to slide to the leftmost end, and at the same time the first sliding device 300 and the second sliding device 500 respectively drive the first positioning device 400 and the second positioning device 600 to slide to the rightmost end, and the loading robot again loads the third vehicle model battery tray 100 onto the third positioning device 800, at which point the state is as shown.
