APPLICATION AND GENERAL INFORMATION

LTA4 laser welders are intended for production and workshop welding of electronic equipment, precision instruments, jewelries and medical devices.

ADVANTAGES OVER SIMILAR TYPES OF EQUIPMENT

  • Advanced energy characteristics and extensive control over laser pulse energy, repetition rate, duration and shape
  • Higher reliability new generation components
  • Flexible module connection and open architecture solution allow to better meet ergonomic requirements
  • Options and modernized modules offer more operation functions
  • Standard package includes a variety of drives and tools (removable operators desk equipped with a height-adjustable workpiece stage with Z-axis precision motion mechanism, control, pedal, optical system with camera monitoring, workpiece positioning drives)

MACHINE LAYOUT

Package includes

  • Laser emitter
  • Optical system
  • Positioning system
  • Power supply unit
  • Cooling system
  • Control units
  • Pneumatic system
  • Operators work place
  • Function modules
  • Spare parts, tools and accessories

Module arrangement

The machine comprises two modules operators work place and a rack for power supply unit and cooling system. The modules are connected by flexible hoses and tubes at least 2 meters long

Modules design advantages:

  • Laser emitter with a dust-proof cover. Laser head with divided metal-ceramic reflectors, which allow to avoid resonator adjustment after lamp replacement
  • Optical system. Includes a telescope with adjustable magnification and changeable objective lenses and camera pointing and monitoring system. Allows double-channel laser spot sizing, adjustment of visual channel acutance and sizing of the laser spot by deepening the focus without changing the acutance of the visual channel
  • Positioning system includes the precision Z-stage with a hand drive for workpiece vertical travel, automatic ? rotary drive for workpiece rotation and a drive for workpiece linear travel, which allow automatic round and linear seam welding
  • Power supply unit for lamp powering. Allows laser pulse shape and duration adjustment
  • Cooling system. Double-circuit thermostable cooling system with liquid floorage control.
  • Pneumatic system. Includes a set of gas nozzles, gas connectors and hoses, filter-regulator, electro-driven valves and rotameter
  • Functional modules include T-slot workpiece stage for workpiece fixing, manual XY-stage, lighting system
  • Operators work place. Compliance with ergonomic requirements. Equipped with height-adjustable workpiece stage and optical system. Includes a visual system monitor, pedal, control unit of laser parameters, optical system and positioning system drives, check indicators of laser output parameters and operation modes
  • Spare parts tools and accessories include consumables (protective class, lamps) for 1 year of operation
  • Technical documentation (technical certificate, specifications and operation manual) contains a detailed machine description and operating instructions accompanied by schemes and drawings
