Why a Promass Coating Line.
The module.
- Very stable and reliable X,Y,Z constructions.
- Minimal maintenance by use of standard components and control systems.
- Upto 7-axis servo and steppermotor driven.
- X-axis, Y-axis.
- Upto 3 pcs. Z-axis.
- 1 pcs. Tilting.
- 1 pcs. Rotation.
- Open construction.
- Easy access to the nozzle’s.
- All nozzle’s at the front (1-line).
Nozzle system.
- Independent Z-axis.
- Upto 3 pcs. Independent Z-axis.
- Standard ‘off the shelve’ nozzle’s; wide range of nozzle’s available.
- Needle,
- Spray,
- Micro spray,
- Short distance between Cartridge and nozzle.
- High accuracy of the nozzle
- Auto calibration of the nozzle’s.
- Standard 0.05 mm repeatability of nozzle position.
- Special applications: 0.02 mm. Repeatability of the nozzles.
The software.
- Easy to use Software.
- Easy to learn.
- Short time to program new products.
- Easy to clean.
Movement of the gantry.
- High speed of the axis.
- Short cycle times.
- We are using Hiwin guiding systems, combined with a tooth-belt drive system.
- For the XY movements, we are using servomotors in combination with the Omron controllers
- Our Z-axis (upto 3 pcs.) are driven by Hiwin guiding and spindle driven.
- Optional:
- We can build a spindle driven movement of the gantry (X,Y).
Checking the viscosity and compensating it in automatic mode ?
- We can offer the option, to add an automatic scale to measure the amount of coating during 1 second of purging.
- This weight is related to the viscosity and opening of the valves.
- Based on these measurement, the speed of the spraying-needle valves can be corrected.
Checking and controlling the dimensions of the area to coat.
- The way of programming is, to load a picture of the product (can be done by the camera installed at the gantry or a “product.jpg” can be loaded from the harddisk).
- With lines, circles, squares and so on, you can program the area to coat (like using paint).
- Every area will be connected with a needle or valve, incl. the parameters.
- Option:
- After the coating process, it is possible to build in a control system (scanner system) to check the coated area.
- Checking based on reflection of the coating under an UV lamp.
Aperture of the spray.
- Option:
- Installing an Omron laser sensor to check the width of the spray beam. The width of the spray beam is depending on:
- Viscosity, depending on type of coating, temp. of the surrounding.
- Opening of the nozzle,
- Pressure on the coating pot,
- Pressure on the shroud air,
- Height of the nozzle above the product,
- Installing an Omron laser sensor to check the width of the spray beam. The width of the spray beam is depending on:
