DICI There are several terms for linear module, such as linear module, rectangular coordinate robot, linear sliding table, etc., which are automatic upgrading units following linear guide, linear motion module, and ball screw linear transmission mechanism. The combination of each unit can realize the linear and curve movement of the load, making the automation of light load more flexible and positioning more accurate.
The linear module was first developed and used in Germany, and its market positioning is in photovoltaic equipment, loading and unloading manipulator, cutting and moving equipment, gluing equipment, patch equipment, etc. The advantages of this manipulator for equipment in this industry are: fast monomer movement speed, high repetitive positioning accuracy, light body quality, small equipment space occupation, and long service life. The application scope of linear modules has been expanding all the time. In our country, the speed is faster. In recent years, the development of linear modules is faster. Especially in Shenzhen, there is a lot of work done, and the quality is also good, which is favored by equipment manufacturers.
The linear module has been widely used in a variety of equipment since its development. It has contributed indispensable contributions to the development of equipment manufacturing in China, reduced dependence on imported complete sets of equipment, and brought more opportunities for engineers who are keen on equipment research and development and manufacturing. At present, linear modules have been widely used in measurement, laser welding, laser cutting, gluing machine, spraying machine, punching machine, dispensing machine, small CNC machine tools, engraving and milling machines, sample plotters, cutting machines, transfer machines, classification machines, testing machines, applicable education and other places.
The development of linear modules is faced with a problem. The miniaturization and enlargement of the modules are difficult to control the accuracy. In particular, the belt driven by the belt itself has no accuracy. It should be installed on the modules. At the same time, the technology to control the accuracy is only available in foreign countries. Germany and South Korea do a better job. Their installation environment is: the ambient temperature of the workshop is controlled at 20C °, the precision of the installation equipment is high, and the precision of the detection equipment is high. Although there are many linear modules in our country, expensive installation equipment and testing equipment are the biggest problems facing production. We should admit that we have to learn from others about these technologies.
DICI linear motor control technology can be basically divided into three categories: traditional control technology and modern control technology. The third is intelligent control technology. Traditional control technologies such as PID feedback control and decoupling DICI control are widely used in AC servo systems. PID control is the most basic control method of the AC servo motor drive system. Decoupling control and vector control are often used to improve the control effect. It is easy and effective to use the conventional control technology when the target model is fixed, linear, operating conditions and the execution environment DICI are unchanged. But for high performance precision feed, the object structure and parameters must be considered. Time varying and uncertain factors such as various nonlinear effects, changes in operating environment and environmental disturbances can provide satisfying control effects to DICI. Therefore, modern control technology is of great significance in the research of linear servo motor control. Common control methods include adaptive control, sliding deformation structure control, adaptive control and intelligent control. Fuzzy logic can achieve better control performance by combining the neural network with the existing mature control methods of DICI (such as PID, H.inf. control) to remedy the advantages and disadvantages.
The above figure shows DICI's linear module. This linear motor platform is driven by imported coreless linear motor. This linear motor platform is widely applicable to industrial applications requiring cost-effective and precise solutions, such as semiconductor wafer detection, microelectronic component testing, access and release, DNA sequencing, laser processing and other fields.
This linear motor platform uses the coreless linear motor as the driving component. The direct drive platform has higher speed, higher acceleration and stable precision performance. The linear motor platform has a more compact structure and higher efficiency compared with the lead screw drive. The single axis linear motor platform provides a better system solution for applications requiring high throughput, high reliability, precise positioning, silent operation, etc.
The ideal positioning accuracy can be easily obtained by laser interferometer calibration and compensation.
Easily realize your requirements for high-precision positioning.
