3D Robot Laser Cladding Equipment Using Siemens PLC Controller

3d robot Laser Cladding Equipment using Siemens PLC controller

Light Guiding System 
The function of light guiding system is to transmit the produced laser beam to laser head, make it finally working on the work piece surface. Light system, including optical fiber, laser head and so on,laser head fixed on the sixth shaft of the robot.
2.1 Feeding fiber: During the laser processing, through the optical fiber, laser will be transferred to the cladding head. The system use LASERLING special conductive fiber. Conductive fiber is equipped with standard connectors, can change with different processing head quickly, easy to dis-assembly and assembly.The fiber has perfect self-protection function during energy transmission; .Specifications are as follows: LLK-D type , core diameter 600 um, length 20 m.
2.2.Optical head: the optical head will conduct a laser beam to the surface for laser cladding or heat treatment (quenching) processing. System is equipped with two sets of laser head: laser cladding head choose imported Laserline, spot size for Ф 3 mm; laser heat treatment (quenching) head choose AK390 type,with one piece inclined mirror reflector and one piece integral mirror, the spot size is 22 mm * 3 mm.

Specification
GS-TEL type laser powder feeding system
Above is the structure schematic diagram for the carrier feeding device, it mainly composed by hopper, rotary blade plate, entrance, export oriented, inlet port, discharging mouth, dc speed regulating motor, etc. Air inlet load/dry air or nitrogen argon, pressure about 3 KGF/cm2 ; through that the locator adjust the rotation speed of dc motor, dc motor driven rotating feed rotating, to realize the setting and adjusting of the feeding amount, motor speed display digitally. The powder feeding machine has the feature of continuous, uniform and adjustable precise powder feeding, etc.
Horizontal rotary worktable
To match usage with semiconductor laser and robots, it is at the same time equipped with a horizontal rotary worktable and machine tool base, main components are casting structure.
Horizontal rotary worktable 
Max.work piece length: 3500 mm; 
Max.work piece diameter: 1000 mm; 
Chuck diameter Φ 630 mm (four); High center: 700 mm; 
Horizontal rotary table bearing: 30 t; With a tail stock thimbles; 
Servo motor: 3.5 KW (KUKA); 
Horizontal rotating speed: 0.15-10 RPM (gear box high speed/low speed two shift); 
Workbench base: 5500 mm * 1000 mm * 280 mm, with T slots, through the T slots,to realize the position of the head stock, tail stock, center bracket,etc

Coaxial powder feeding system
Equipped with paraxial pneumatic type coaxial feeding device, installed below the laser head,move with the laser head, output powder overlaps with light beam focus, It is used for laser cladding processing of artifacts or work piece local repair, convenient, quick, efficient. It can feed powder with coaxial laser beam to complete the processing for the complex surface laser cladding.
