Background of the project:
In the early 1990s, due to the increase in material processing requirements, laser marking, a new technology developed after laser welding, laser heat treatment, laser cutting, laser drilling, and other applied technologies, has become an indispensable processing tool. Laser marking technology has become the most widely used and most mature technology in the field of laser processing with its new contactless, non-polluting and non-abrasive marking process.
The core of laser marking equipment is the laser marking control system. Therefore, the development of laser marking is the development process of the marking control system. In just 7 years, the control system has experienced the large-format era, the rotating mirror era and the galvanometer era in the field of laser marking, and the control mode has also experienced from software direct control to the control of the upper and lower machines to the real-time processing. A series of evolutions that are time-multiplexed.
Project principle:
The laser marking system is mainly composed of Advantech IPC, laser, galvanometer scanning system and f-θ lens. The schematic diagram of the system structure is shown in the figure below:
The power system is connected to 220V (50Hz) power supply for IPCs and (gas/solids) lasers respectively. The IPC controls the galvanometer scan system and laser power supply through laser marking software. When preparing for marking work, the IPC sends a signal to the power system to control the laser switch light and its laser power level. At the same time, a certain transformation is made according to the marking coordinate data and transmitted to the galvanic mirror scanning system. The galvo mirror scanning system receives The signal adjusts the X/Y-axis oscillating mirror, that is, the X/Y-axis oscillating mirror is deflected by a certain angle. At this point, the complete optical transmission path is that the beam emitted by the laser is refracted by the X and Y galvanometers, and then is incident on the surface of the workpiece to be marked.
System Features:
Advantech IPC is mainly used to transmit and process laser marking signals in this system, and coordinate the work of each part through the timing function. Due to the timely performance requirements of laser marking, the selection of IPCs is the key. Not only is it required to be able to respond quickly, but it is also characterized by stability, safety, and anti-jamming, so that it can be normally produced under harsh operating conditions. The industrial computer mainly completes the following tasks in the laser marking system:
1. The main switch of the power system is turned on. After the operator has set relevant parameters on the industrial control computer, the industrial computer controls the hardware parts of the system.
2. The IPC extracts the coordinate data of the marking and converts it into an angular deflection signal that can be recognized by the galvanometer system through a certain algorithm.
3. When the marking of a single character is completed, the IPC controls the Q parameter to turn off the laser. At this time, the laser is still in operation. After the entire marking task is completed, the laser power is set to 0, thus completely turning off the laser.
4. The industrial control machine shall carry out timely monitoring and control of the marking process and record and store the information.
Project evaluation:
After the verification of the production of thousands of characters, the high control accuracy has been achieved and the customer's requirements have been accurately completed.
1. High stability: due to the use of a highly reliable Advantech original machine for processing, to enhance the stability of the system;
2. Flexible configuration: It adopts distributed structure and flexible configuration;
3. Cost-effective: Advantech IPC has better scalability, rational use of various methods, and optimizes the cost of the entire system.
Dc Gear Motor can be defined as an extension of Dc Motor which already had its Insight details demystified here. A dc Gear Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a dc gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.
Application field: usually used Electronic door locks, shutter motor, home audio equipment, sweep the floor machine robot
Features: dc gear motor drive precision, small volume, large torque, low noise, durability, low energy consumption, customized power design,easy installation, easy maintenance;Simplify design and save space.
Method of use: the best stable in horizontal plane, installed on the dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Dc geared motors should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Dc geared motors should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of dc gear motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
