The panasonic LAPRISS laser Beam synthesis technology namely the WBC (where Beam Combining) technology, has developed high brightness semiconductor laser directly, it will be more low power laser Beam through the synthetic technology of the Wavelength of the coupling into a high brightness, reach 2 kw, 4 kw, 6 kw and a series of high power laser Beam, and the Beam quality reach 4 mm mrad, meet the requirements of laser remote welding and cutting, we named this kind of laser for direct semiconductor laser (DDL), compared with other laser pointer, It has higher efficiency, higher reliability and smaller size.
Panasonic laser head is the industry’s lightest scanning laser head, weight is only 4. 5 kg, so it can carry on more quickly, panasonic TM series robot flexible, greatly improving the efficiency of laser, panasonic laser is not a simple focus on guns, but with functions of scanning, laser head and set the robot has two external shaft motor, and with laser refractive lenses internal connection, through changing the Angle of the lens, can be achieved under the condition of the laser head did not move, move through the spot, scanning the 9 kinds of graphics, the graphics are commonly used in laser welding of graphics, can be called directly, and can be edited within 16 mm diameter, the size of the graphics The convenience of laser system is greatly improved.
Laser welding requirements for the precision of the workpiece is very high, because the light spot diameter is very small, generally for fractions of a millimeter, if there is gap between weld position deviation or weld, there will be partial welding and welding welding defects such as leakage, it is also the customer worry about a topic, for panasonic laser scanning head, so can realize flare side spin, side in the robot driven by linear motion, we in the welding of spiral welding, the advantages of spiral welding method: 1) the weld width increase. Because the laser spot is small, the additional rotation motion is equivalent to increasing the spot size, thus increasing the weld width. 2) increase gap adaptability to a certain extent. Since the beam has an additional rotating motion while advancing, the adaptability of the gap can be improved while the weld width is increased. In addition, because the boundary of spiral swing method is different from that of normal laser welding, it is beneficial to restrain the crack growth. Therefore, spiral welding can greatly reduce welding defects and improve welding quality.
In terms of operation, panasonic LAPRISS laser system to provide more convenient way of operation, 1) laser and robot to realize digital communication, laser requires no additional computer control of panasonic, can completely by the robot controller to control it, both the setting of the laser power and the selection of the spectral optical path, can completely avoid the wrong operation or response. 2) panasonic robot controller can easily control the robot, laser head and laser, increasing the operability of the equipment. 3) equipped with laser welding navigation system and built-in laser welding expert database in the controller, the welding process is simple and easy to learn, and the welding can be completed by setting key requirements such as material, plate thickness and joint form. 4) auxiliary red light for demonstration, a guiding light unit is installed on the laser head, which can send out a red line, and the center of the laser head can send out the teaching spot. When the red line and the teaching spot coincide, it is the focus position. The height ruler is no longer needed to measure the focus, making the operation more simple and convenient.
