MOTOPAC laser welding packages
The MOTOPAC laser welding packages combine a MOTOMAN robot and a YRC1000 with laser processing equipment such as a galvano scanner head. For the manipulator specifications, grease and battery replacement, follow the pages of the base robot (GP50, GP25); the package manuals do not cover them.
| Package | Base robot | Head |
|---|---|---|
| MOTOPAC-RL3D1200-GP50 | MOTOMAN-GP50 + YRC1000 | Galvano scanner head (working distance 1200 mm) |
| MOTOPAC-RL2D300-GP25JP | MOTOMAN-GP25 + YRC1000 | Compact galvano scanner head and driver (working distance 329.5 mm) |
Main specifications of the heads
| Item | RL3D1200-GP50 | RL2D300-GP25JP |
|---|---|---|
| Laser | Fiber-delivered high-power multimode, wavelength 1060 to 1080 nm, up to 20 kW (center plus ring) | Wavelength 1050 to 1090 nm, 8 kW |
| Fiber connector | HLC-16 | QBH |
| Working distance | 1200 mm (from the end of the protective glass holder) | 329.5 mm |
| Coverage area | φ520 mm (Z = −225 mm) / φ630 mm (Z = 0) / φ720 mm (Z = +182 mm) | φ25 mm |
| Optical magnification | 8.5× | 3× |
| Spot travel speed | X-Y 6 m/s, Z 8 m/s | 8 m/s |
| Repeatability | X-Y ±0.05 mm or less | ±30 μm or less |
| Mass | Head 31.5 kg | Head 15.8 kg, air knife 2.5 kg, driver 4 kg |
| Protection class | Equivalent to IP54 (except the fiber connector mating part) | Equivalent to IP54 |
| Power supply | 24 V ±1.2 V, 10.6 A | 24 V ±1.2 V, 13.7 A |
| Operating temperature | 5 to 40 °C | 5 to 40 °C |
The RL3D1200-GP50 head needs cooling water (1.0 L/min, 0.4 MPa, 27 to 33 °C). It communicates over CAN, and output is controlled by two analog 0 to 10 V channels.
Maintenance
| Item | Interval | What to do |
|---|---|---|
| Protective glass | Daily / 1 year | Clean and check the transmittance. Replace it if dirt or scratches cannot be removed, if transmittance is below 90 %, or after 1 year of use |
| Galvano scanner head | Daily | Check for collision damage. Replace or repair if transmittance is below 90 % even with a new protective glass |
| (GP25 version) Galvano scanner driver | Daily | Check the condition |
| Overall appearance / mounting points | Daily | Clean / retighten |
| Robot internal leads and dress cables | Daily | Check for abnormalities (on the GP25 version, also listen for abnormal noise). Replace when abnormal or at the robot overhaul |
| Fixed cables (analog, safety, CAN, 24 V, etc.) | Daily / 1 year | Measure the analog values every year |
| Hoses and fittings | Daily | Check for leaks |
| Robot and head (and driver on the GP25 version) | 36000 h | Overhaul by the YASKAWA service |
- Measure the transmittance with a calibrated power meter.
- To adjust the tool point, follow the YRC1000 remote laser function manual.
