近年来，我国光伏玻璃在全球市场的占有率保持在90%以上，是全球最大的光伏玻璃生产国。随着光伏行业技术的发展以及企业产能的持续扩张及环保意识的提升，光伏玻璃行业正加速提升“新质生产力”，以科技创新推动产业升级，进一步释放发展新动能。某大型上市光伏玻璃企业，旨在通过无人叉车智能物流系统的导入，实现光伏玻璃原片到深加工环节的物流智能化及打通上述环节数据链，从而推动光伏玻璃行业高质量发展。
Difficulty
1. The weight of the material is 3 tons, and the original glass is fragile
The upper and lower pieces at the beginning and end of the production line are transported manually and the weight of the material is up to 3 tons, and the original glass sheet is easily damaged due to low stability during long-term manual operation, and the quality is difficult to guarantee and the traceability of the production materials of the production line is difficult to achieve.
2. The on-site environment is empty, and there is a problem of navigating off the map in conventional SLAM navigation
The production site environment of glass manufacturing enterprises is empty, and the requirements for forklift AGV navigation technology and communication stability are high. There are few reference objects in conventional SLAM navigation and mapping, and there is a problem of navigating off the map, while AGV dynamic SLAM navigation can run stably in outdoor open scenes.
3. Docking with the loading machine, the accuracy is required to be ±5mm
By integrating laser vision technology, AGV realizes adaptive adjustment of left and right offset, front and rear offset and angle adjustment, etc., to improve the precision and accuracy of end operation and achieve accurate cargo forking.
Solution
通过多台负载3吨的平衡重式无人叉车完成从原片到平面库再到上片机、L架到暂存区之间的自动化搬运，同时基于艾吉威自研激光SLAM+视觉二次位定位技术、天枢调度系统AGVS、定制WCS系统、定制叉取稳定器及其他光伏玻璃行业定制开发技术，实现与两台重载RGV以及上片机的系统对接交互。
In addition, in terms of the accuracy requirements of pick-up and unloading of goods on the loader, the adaptive adjustment of left and right offset, front and rear offset and angle adjustment is realized through the fusion of laser vision technology, so as to improve the accuracy and accuracy of terminal operation and achieve accurate cargo forklifting.
In order to prevent the glass from tilting, AGV optimizes the design of the body structure and counterweight according to the tilting state of the glass in the mechanical structure of the car body, and adds an anti-dumping mechanism; In addition, the vehicle body motion control technology is optimized to ensure that the unmanned forklift has a uniform speed and stability when performing the pick-and-place action.
