PB300CE
Fiber transmission laser outputs laser beams through fiber to conduct welding and realize non-contact remote operation which is convenient for integration with automation production line; fiber transmission laser adopts a laser power real-time feedback control system. This system can, according to preset laser waveforms, work together with laser power detection device to automatically realize real-time closed-loop control of laser power supply, adjustment of output current of power supply, and stable laser energy. The laser power real-time feedback control system eliminates the instability of laser energy caused by power grid fluctuations, water temperature changes, xenon lamp aging and other problems, thus improving the consistency of welded products.
Laser power supply firstly ignites the pulsed xenon lamp. With pulsed discharge of laser power supply towards xenon lamp, light wave of certain frequency and pulse width is generated. The light wave is then radiated via pumping cavity onto the Nd: YAG crystal, thereby exciting the Nd: YAG crystal to emit light, and with further resonance of laser resonant cavity, pulsed laser with a wavelength of 1064nm is produced. The pulsed laser is then expanded, reflected (or transmitted via fiber optic) and finally focused onto the object to be welded; under the control of PLC or industrial PC, NC platform is moved to complete welding. Such parameters as laser frequency, pulse width and duty ratio as well as worktable speed and motion direction can all be controlled by SCM, PLC or industrial PC. And energy of pulsed laser can be regulated by setting different laser frequency and pulse width.
PB300CE has advantages of good beam, fine spot, strong penetrating ability, flexible installation, remote control and operation, etc. Especially, it is far superior to current feedback or non-feedback laser welding machine in energy stability control, which is the unparalleled advantage of PB300CE in China. Nowadays, it is widely used in the welding of mobile phone shells, laptop shells, optical fiber connectors, electronic components, advanced instruments, medical equipment and other precision parts.
