Recently, China's first and largest all-carbon fiber roof structure building, the Zen Hall, was officially built in Jinshanling, Chengde, Hebei.

It is reported that for the complex and special-shaped hyperbolic roof, the Zen Hall project adopts the digital component production + assembly method throughout the process, intelligently disassembles all hyperbolic modules, and uses a seven-axis high-degree-of-freedom robotic arm engraving system to accurately make hyperbolic modeling molds, 1:1 pre-assembly in the factory, and after the carbon fiber roof is transported to the site, the roof installation is completed within 24 hours. The entire construction process is inseparable from the assistance of Dajie Robot.

Founded in 2016, Dajie Robotics is a provider of intelligent construction solutions, focusing on the development of intelligent industrial robot systems.

After six years of deep cultivation in the construction field, Dajie has gradually become famous. So far, Dajie has provided intelligent robot production solutions for more than 100 factories, forming a matrix cloud factory production system; at the same time, it has provided intelligent construction services to hundreds of real estate developers, domestic and foreign architectural design agencies and architects, realizing the digital intelligent manufacturing of the construction industry D to M (design to manufacturing).

The intelligent manufacturing solutions provided by Dajie for the building steel structure industry mainly include Part bevel cutting, profile 3D cutting, and steel assembly welding , covering A complete set of comprehensive solutions from parts and components processing to component assembly and welding. It uses automation technology to improve the manufacturing level of steel structure industrialization and provide customers with high-quality, cost-effective intelligent solutions.

With the accumulation and development of technical strength and intelligent manufacturing experience, Dajie bevel cutting robots have been widely used in the production and processing of cross columns, H-shaped steel column parts and steel structure components. The components it produces are used in high-rise steel structures and tower projects such as Shenzhen Huiyun Center and Huaqiang Fantawild Building.

The production characteristics of building steel structure projects mainly revolve around customized production of multiple batches and small quantities of projects. This production characteristic is highly consistent with the customized production model of the coal machinery industry. The coal machinery industry has become the first battlefield for the application expansion of Dajie's intelligent solutions.

In recent years, with the in-depth development of coal mining mechanization in China and the recovery of the coal mining industry, the operating income of China's coal machinery companies has steadily increased. According to statistics from the Coal Machinery Industry Association, in 2020, the fixed asset investment in China's coal machinery industry was 400 billion yuan, and the market size of coal machinery equipment has reached 141.6 billion yuan .

As international energy prices are expected to remain high in the future due to the complex international situation , domestic and foreign coal prices are also expected to remain high. Coal companies will maintain high profits , which is expected to promote coal mine capacity renewal, intelligent transformation and replacement, and equipment demand is expected to increase.

What is the confidence of Dajie to enter the coal mining machinery market? What kind of intelligent blood can it inject into the traditional coal mining machinery industry?

Focus on industrial software RoBIM

Comprehensive coal mining equipment, including roadheaders, coal mining machines, scraper conveyors and hydraulic supports, are collectively referred to as "three machines and one support". Through the coordinated use of roadheaders, hydraulic supports, scraper conveyors and coal mining machines, tunneling, coal cutting, coal loading, coal transportation and support operations in coal mine tunnels can be achieved. Since the tunnel conditions and mining heights of each coal mine working face are different, coal mining equipment often needs to be customized according to the conditions of the mining tunnels.

In order to comprehensively improve the efficiency of the industry, coal mining machinery companies need to solve many production pain points in their production and manufacturing: large errors in incoming materials from the previous process, low processing accuracy of workers, large variations in bracket specifications and mine requirements, mainly customized orders, multiple batches and small batches of production mode, and a wide variety of robot teaching methods, which require a lot of manpower for debugging, is time-consuming and labor-intensive, and increases corporate costs.

As coal mining equipment gradually enters the intelligent, high-end transformation and upgrading, traditional production equipment can no longer meet the growing demand for high-end equipment. In the production of high-end hydraulic supports, the slowest production pace and the most complicated operation are the large-scale and fragmented small-piece bevel cutting. Support manufacturers are in urgent need of a teaching-free intelligent solution to release the production bottleneck of manual and traditional teaching operations.

Compared with traditional robot integration solutions and pure vision solutions, Dajie's intelligent beveling solution is equipped with professional and powerful beveling cutting software RobimCut.

Rob im Cut software It is built using the self-developed RoBIM industrial software platform, connecting model drawing data with the motion control of industrial robots, and using high-precision visual technology to enable the robot to quickly identify the geometric information of the workpiece, and through modular algorithms and process expert libraries, it can quickly and automatically generate cutting paths without programming, and with integrated control of hardware and software, it can achieve one-click production of large and small batches, quickly release production bottlenecks for manufacturing companies, and effectively improve cutting efficiency and product quality.

RobimCut plasma beveling cutting center can meet the requirements of automatic flexible cutting of straight lines, arcs and roundness of carbon steel plates with different sizes and thicknesses, and is suitable for coal mining machinery, engineering machinery, ships, bridges and other industries.

Achieve 95% specification component processing

Dajie has launched two RobimCut parts beveling plasma cutting centers for coal mining machinery manufacturers, namely a robot beveling cutting single station and an extra-long workpiece robot beveling cutting station. The two cutting centers are equipped with a variety of production modes, taking into account the different production needs of coal mining machinery manufacturers.

The robot bevel cutting station is mainly used for fully automatic bevel cutting of small and medium-sized bevel parts. The double-station cutting can achieve uninterrupted production, and with the help of 3D visual algorithms, it can accurately identify the size of incoming materials and update the robot cutting path in real time, achieving the best cutting effect and the highest production efficiency.

Robotic beveling cutting single station

The ultra-long workpiece robot bevel cutting station can meet the processing needs of ultra-long workpieces with a maximum length of more than 6 meters. It adopts global visual positioning and multi-segment reconstruction to perfectly eliminate the incoming material errors of ultra-long workpieces and solve a series of problems such as long workpieces warping up, achieving 1mm-level processing accuracy. With the support of the robot's free planning algorithm, it can realize fully automatic bevel cutting in a variety of placement methods.

Robotic beveling cutting station for ultra-long workpieces

The two RobimCut part beveling plasma cutting centers can meet 95% of the beveling workpiece production needs in the coal mining machinery industry.

In addition to RobimCut's standard cutting modules, Dajie also provides customized module services for customers with customized needs to meet the customized production needs of different manufacturers. Customized modules include a series of customized module services such as loading and unloading modules, bevel surface grinding modules, and integrated cutting and grinding modules.

The landing plan can be freely selected

With the help of the core software RoBIM , Dajie has completed multiple implementation cases in the coal machinery market, including many leading companies in the coal machinery industry.

In response to the demand for standard groove cutting products, Dajie provided a medium and thick plate plasma groove cutting robot solution for a heavy coal machinery enterprise in Shanxi , including self-developed industrial software RoBIM , advanced visual algorithms, dual-station cutting stations and ultra-long workpiece cutting stations. This solution helps customers increase the comprehensive output value of a single production cycle by 3.5 times compared to ordinary supports when producing high-end large-mining height hydraulic supports, and increase the production capacity of hundreds of small batch workpieces by 2-4 times. At the same time, each single station can save the labor cost of one skilled operator. One worker can take care of two workstations at the same time and coordinate the processing of multiple workpieces, which greatly improves work efficiency.
