Factory automation, also known as shop automation, refers to the automatic completion of all or part of the manufacturing process. Since the beginning of the 21st century, the concept of "people-oriented" and "energy-saving and environmental protection" has been deeply rooted in the hearts of the people, and new requirements have been placed on factory automation.
At the beginning of the "Industry 4.0", many companies have embarked on the road of factory automation transformation, and the unmanned factory seems to gradually become the development trend of the future factory. However, the fully automated assembly line has sporadically appeared in large enterprises. Although the government has vigorously promoted the robot substitution policy, many enterprises have received the subsidies issued by the state, which is to put the equipment in the production workshop. Automated transformation costs huge manpower, material and financial resources, but why is it very little? You must know these big mistakes!
1, the robot as a smart device, not simply installed and debug can be used. If you ignore the development and application of robots, many robots will not be bought or used improperly. Take robots and sports athletes to make an analogy. A group of good athletes (robots) plus a good coach (system integrator) is the key to winning the entire sports team.
2, the real automation upgrade, not a simple workstation or machine replacement can be completed, but an extremely complex system engineering. The automation transformation needs to be carried out in a quantitative manner. Starting from the more mature automation technology, starting from the urgent need to upgrade and renovate the factory, it is necessary to pursue one step.
3. The application of robots is one of the most representative aspects of automated upgrades. But it does not mean that it can solve all problems. Pneumatic hydraulic control and non-standard equipment automation is also one of the most important means of achieving automation. Especially for some special applications, robots can't solve, non-standard automation equipment is the answer. Automated upgrades and transformations must not be seen only by robots, and multiple channels are the best.
4. Products produced by automated production lines should have sufficient output; product design and process should be advanced, stable, and reliable, and remain basically unchanged for a long time. Not all processes are suitable for automated retrofitting. The use of automatic lines in large batches and mass production has significant economic benefits.
5. The concept of Industry 4.0 and China Manufacturing 2025 has been very hot recently, and many companies have followed suit blindly. Manufacturing companies should pay more attention to the actual technology and problem solutions. When it comes to generalized management automation with information as the core technology, the industry 4.0 era will also emerge.
With the continuous development and innovation of computer technology, wireless technology, fieldbus technology, industrial Ethernet technology, IT technology, robot technology, sensor technology and safety technology, factory automation has experienced single machine automation, workshop automation, and the whole plant. After several important stages such as centralized control, the company is developing integrated automation, that is, integrating process control, supervision and control, product design, quality monitoring, and factory management, using modern control theory, large system theory, artificial intelligence, 4C. Technology to achieve optimal control, hierarchical control, decentralized control, test automation, building automation, information processing and business decision automation to further improve work efficiency, quality and safety, energy and raw materials.
The automatic biochemical analyzer is an instrument that measures a specific chemical composition in body fluids according to the principle of photoelectric colorimetry. Due to its fast measurement speed, high accuracy and small consumption of reagents, it has been widely used in hospitals, epidemic prevention stations and family planning service stations at all levels. The combined use can greatly improve the efficiency and benefits of routine biochemical testing.
principle
The automatic analyzer is to automatically run all or part of the steps of sampling, mixing, warm bath (37°C) detection, result calculation, judgment, display and printing results and cleaning in the original manual operation process. Today, biochemical tests are basically automated analysis, and there are fully automatic biochemical analysis systems designed for large or very large clinical laboratories and commercial laboratories, which can be arbitrarily configured according to the laboratory's testing volume.
Whether it is the fastest-running (9600Test/h) modular fully automatic biochemical analyzer today, or the original manual-operated photoelectric colorimeter for colorimetry, the principle is the use of absorption spectroscopy in spectroscopic technology. It is the most basic core of the biochemical instrument.
Optical system: is a key part of ACA. Older ACA systems used halogen tungsten lamps, lenses, color filters, and photocell assemblies. The optical part of the new ACA system has been greatly improved. ACA's beam splitting system can be divided into front splitting and rear splitting due to different light positions. The advanced optical components use a set of lenses between the light source and the cuvette to convert the original light source. The light projected by the lamp passes through the cuvette to bring the beam to the speed of light (unlike traditional wedge beams), so that the spot beam can pass through even the smallest cuvette. Compared with traditional methods, it can save reagent consumption by 40-60%. After the spot beam passes through the cuvette, the spot beam is restored to the original beam through this group of restoration lenses (wide difference correction system), and is divided into several fixed wavelengths (about 10 or more wavelengths) by the grating. The optical/digital signal direct conversion technology is used to directly convert the optical signal in the optical path into a digital signal. It completely eliminates the interference of electromagnetic waves to the signal and the attenuation in the process of signal transmission. At the same time, the optical fiber is used in the signal transmission process, so that the signal can achieve no attenuation, and the test accuracy is improved by nearly 100 times. The closed combination of the optical path system makes the optical path without any maintenance, and the light splitting is accurate and the service life is long.
Constant temperature system: Since the temperature of the biochemical reaction has a great influence on the reaction results, the sensitivity and accuracy of the constant temperature system directly affect the measurement results. The early biochemical instruments used the method of air bath, and later developed into a dry bath with constant temperature liquid circulation which combines the advantages of dry air bath and water bath. The principle is to design a constant temperature tank around the cuvette, and add a stable constant temperature liquid that is odorless, non-polluting, non-evaporating and non-deteriorating in the tank. The constant temperature liquid has a large capacity, good thermal stability and uniformity. The cuvette does not directly contact the constant temperature liquid, which overcomes the characteristics of the water bath type constant temperature being susceptible to pollution and the uneven and unstable air bath.
Sample reaction stirring technology and probe technology: The traditional reaction stirring technology adopts magnetic bead type and vortex stirring type. The current popular stirring technology is a stirring unit composed of multiple groups of stirring rods that imitate the manual cleaning process. When the first group of stirring rods is stirring the sample/reagent or mixed solution, the second group of stirring rods performs high-speed and high-efficiency cleaning at the same time. The set of stirring bars also undergoes a warm water washing and air drying process at the same time. In the design of a single stirring rod, a new type of spiral high-speed rotating stirring is adopted, and the rotation direction is opposite to the spiral direction, thereby increasing the stirring force, the stirred liquid does not foam, and reducing the scattering of light by microbubbles. Reagent and sample probes are based on the principle of early capacitive sensing, but slightly improved to increase the alarm of blood clots and protein clots, and re-test results according to the alarm level, reducing sample aspiration errors and improving the reliability of test results. . Large-scale biochemical instruments can detect more than 1,000 tests per hour, so automatic retesting is very important. Subjective evaluation of test results and manual retesting can no longer meet clinical needs.
Other aspects: barcode recognition of reagents and samples and computer login. Due to the lack of barcode recognition function of early biochemical instruments, there are more opportunities for errors. In recent years, both imported and domestic chemical instruments have adopted barcode detection. The use of this technology in biochemical instruments has provided technical support for the development of high-speed ACA, and also made the instrument quite supportive. The software development is simple and easy, therefore, barcode detection is the basis for the intelligence of the instrument. Open reagents, as an important factor for hospitals to choose models, whether the instrument supports open reagents is very important. After the reagents are opened, hospitals and scientific research units can choose their own reagent suppliers, and have a greater degree of freedom in measuring the price, the reliability of the test results, and the validity period of the reagents. Ion Selective Electrode Analysis Accessory (ISE), human serum and urine electrolyte indicators are very important, and hospitals can save money by adding ISE to the ACA system.
