Quasi-simultaneous welding is a combination of contour welding and simultaneous welding. With quasi-simultaneous welding, the galvano scanner of the laser head directs the laser beam around the components so that the components combine quasi simultaneously along the welding seam. This welding technique is one of the most flexible joining technologies and allows for dramatic improvements in design freedom. In contrast to the technique of contour welding it offers a high tolerance compensation and low processing times.Weitere Abbildungen
High-quality plastic welding
The VL-W1 Laser welding system is equipped with our original FAYb fiber laser. It is based on the technologies we have accumulated in the last decades through the manufacturing of laser marking systems. The new Laser welding system VL-W1 has taken the proven and tested fiber technology one step further and guarantees welding results of the highest quality.Weitere Abbildungen
The new Panasonic laser welding system creates high-quality welded joints on plastic components. The laser beam passes through the laser transparent (upper) material and is then absorbed by the laser absorbing (lower) material. The laser-absorbing material heats up and melts together with the laser-transparent material by heat transmission. During welding, a joining pressure adapted to the workpiece supports a precise junction of the plastic components.Weitere Abbildungen
Precise laser beam
Thanks to Panasonic's fiber laser technology, the laser beam of the VL-W1 series has achieved the quality level M2 < 1.1.
M2 is a numeric value which indicates the quality of the laser beam. The closer this value is to 1.0, the higher the quality of the laser beam.
3D plastic geometries
The combination of the high-quality beam with a level of M2 < 1.1 and our proven optical design has realized a parallel light beam with minimal beam widening. This allows working on different planes in a height difference of +/- 15mm. Furthermore, it is possible to weld 3D plastic geometries to one another.
Parallel laser beam
The parallel laser beam allows precise welding even very close to the edge of parts. This feature supports a great design freedom when it comes to designing plastic components. At the same time, component design is becoming much less expensive. Conventional laser welding systems do not offer these advantages because they produce a conical laser beam (left graphic) which is deflected at the component geometry.
Variable beam diameter
The variable beam diameter mechanism enables the adjustment of the beam diameter between 0.7 and 2.0mm. Therefore, the desired welding width can be set without replacing the optical parts.
Integrated power correction for curved sections
With normal laser output, the heat tends to accumulate more at curved sections. This may lead to uneven welding results. The VL-W1 Laser welding system optimizes the laser output at curved sections to achieve a uniform welding result even for complex welding patterns.
The spiral width can be flexibly changed in the longitudinal or transverse direction. An appropriate pattern can be easily set according to the workpiece and the required laser energy. Even thick welding seams are no problem with the spiral function.
Laser output power monitoring
The VL-W1 series features a high-performance monitor in its head. It monitors the laser output power accurately in real time during welding. This is extremely useful for recording and managing the laser output power.
The operation with the color touch panel (optional) is intuitive and easy. Besides inputting parameters, you can also set up any welding geometry on the touch panel. The laser position in relation to the component can be checked with the red pointer.
CAD data import function
Complex patterns can be produced with CAD software and imported into the VL-W1.
Data check function
With the data check function, the code reader compares the 2D code with pre-registered data and reads the code only when the 2D code matches the predefined settings. This function provides two setting types: "Perfect match" and "Partial match." This way, you can prevent defect products from being mixed up with perfect products.
The Ethernet compatibility enables the transmission of not only the read data but also of images and quality verification data. The 2D Code Reader LP-ABR10 is equipped with a PLC link function for easy configuration of a network.
The sheer range of industries and applications for which Panasonic provides first-class solutions and systems is astounding. Our experts are able to draw on years of experience, helping them solve custom applications quickly and to perfection – just take a look at the photo gallery for some practical examples.
