In order to cooperate with the production line production mode, the laser printer is also equipped with the corresponding pipeline marking mode under the combination of computer technology information, which not only ensures the marking speed, but also has no influence on the marking effect. Then, if you want to set the pipeline mode of the laser printer, the following steps are taken to debug the system by taking the fiber laser printer as an example;
(1) Jog control module; click the button to enter the jog control module. This module of the laser printer is mainly used for jog control of each axis. After setting the card number, axis number and motion parameters, click the button.
(2) The IO control module clicks the button to enter the IO control module. I/O test module interface. Laser printer, fiber laser printer, semiconductor laser printer, carbon dioxide laser printer. The price of the laser marking machine is in this module. The user can view the status of the universal input port and the dedicated input port. The red light indicates the high level input, the green light indicates the low level input, and if it is wrong, the blue light is on.
In the dedicated input, the check box after each signal is used to set whether to enable the dedicated input port, the selected indication is used as a dedicated input, and the cancel indication is used as a universal input port. Two radio blocks, active high and active low, can be seen after the alarm signal to set the trigger level of the dedicated input signal. The button below the interface is used to set the signal of the 24 universal output ports, and the initial button is red, indicating that the corresponding output port is in the off-off state (all common output ports are OC gate output mode).
After clicking, it turns green, indicating that the corresponding output port is in the on-ON state (conducting with the externally input 24V power ground). The default axis dedicated signal of the control card is active high. In this program, the axis signal is set to low level for easy debugging. Please pay attention to the user's use. At this time, the state of the marking of the laser marking machine of the assembly line is basically debugged.
(3) Command test module Click the button to enter the IO control module. In the command test module, the user can view and test all the functions provided by the MPC2810. In the process of using the laser marking machine software, the user only needs to select the function name in the list box, double-click the corresponding parameter box, input the correct parameters, and then click the button to execute the corresponding instruction. If it is a running motion command, to stop the motion, just click on the corresponding buttons in the back. If you find that the function does not work properly after clicking Run, you can find get_last_err in the function list box. Run the function to get the error code, check the error code table in the programming manual to understand the cause of the error.
(4) Parameter setting module Click the setting menu in the menu bar, and the parameter setting dialog interface will pop up. In this module, the user can modify the pulse output mode, feedback and other parameter settings. Modify the parameters and click the OK button to complete the operation. Upon reaching this step, the system commissioning of the fiber laser printer for the pipeline mode is completed.
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.
