Why Choose G-AMC Laser Check System?
In The Actual Production Process, When Machining Sheet Metal Parts With High Precision Requirements, It Is Often Encountered That The Thickness Of The Sheet Metal And The Existing Stress Are Different, Resulting In Changes In The Angle, Such As:
Inconsistent plate thickness
Different rebound performance
Change of oxide layer or rolling line on the plate surface
Changes in mechanical properties of materials in different batches or the same batch
In Order To Solve The Above Problems And Help Users Complete Mass Production Tasks With High Quality, We Have Developed A Solution Dedicated To Detecting Bending Angles And Automatically Correcting Them, Namely G-AMC Laser Angle Check System.
It is not only an angle check, but a complete closed loop system perfectly connected with the press brake.

What Is G-AMC?
G-AMC Laser Angle Check System Is ,Composed Of Angle Detection Sensor, Customized Software, System Connection Port, Frame Deformation Measuring Instrument, Drive Shaft For Sensor Movement, Parking Space, Etc., Thus Forming A Complete Closed-Loop System For Real-Time Angle Measurement And Compensation.

It Ensures The Bending Angle Accuracy During The Sheet Metal Bending Process, Improves The Sheet Metal Processing Quality, And Effectively Reduces The Scrap Rate Of The Work Piece.
It Is Especially Suitable For Automatic Unit Of Bending Machine Or Automatic Production Line Project. The Laser Angle Detection Device Can Detect The Characteristics Of Different Plates During The Sliding Block Pressing, Maintain Real-Time Communication With The CNC System, Calculate And Control The Precise Position Of The Sliding Block's Lower Dead Point, And Adjust It Through CNC Control Y1, Y2 And Deflection Compensation System, So As To Ensure That The First Bending Can Achieve The Preset Perfect Effect!
Working Principle
Through CMOS /CCD The Camera Scans The Projection Of The Laser Projected On The Sheet Surface To Measure The Bending Angle. The Angle Between The Observation Axis Of The Laser And The Camera Determines The Measured Distance, Which Is Used To Calculate The Angle Between The Sensor And The Sheet. And Calculate The Bending Angle Together Through The Second Sensor In The Opposite Direction .

Real Time Measurement, Angle Detection Sensor And Configured High-Speed Gige Camera Can Realize Real-Time Measurement, With Refresh Rate Up To 100HZ .
The Compensation Process Starts Bending And Compensates In Real Time Until The Bending Force Drops To A Preset Value. For 250T And Above Tonnage Equipment, Strain Gauges Shall Be Installed At C-Shaped Ports On Both Sides Of The Bending Machine Frame. Because The Deformation "Opening" Phenomenon Of Wallboard Under Reaction Force During Bending Will Lead To "Error" Of Grating Ruler Measurement Movement. The Installation Of Strain Gauge Can Be Used To Measure The Opening Deformation Of The Racks On Both Sides. The Opening Deformation Is Fed Back To CNC Through The Strain Gauge And Amplifier, And The Spring Back Angle Is Calculated And Compensated In Real Time Through Real-Time Communication With The CNC System.

G-AMC Application
Angle Detection, It Can Be Set To Detect Only The First Piece Or The Initial N Pieces; It Can Also Be Set That After The First Piece Is Detected, The Rest Of The Work Pieces Follow The First Piece Detection Mode. When The Following Mode Is Selected, The Laser Check Angle Detection Compensation System Does Not Need To Move Repeatedly, Saving The Beat Time. During The Processing Of The Same Batch Of Work Pieces, Sampling Inspection Can Be Selected As Required
For Workpieces With Complicated Bending Steps Or Bending Surfaces With Small Side Lengths, The First Tool Bending Detection Can Be Set To Ensure That The First Tool Reaches A Satisfactory Result. For Other Bending Steps, The "Learn" First Tool Mode Can Be Selected For Detection To Save Bending Beat Time.
It Can Move Freely Along The Length Of The Sheet, And The Moving Speed Can Reach 1000/S.
The Middle Point And Two End Points Of The Workpiece Can Be Set For Detection, And The Left, Middle And Right Points Within The Full Length Range Can Also Be Set For Detection.
According To The Lower Die With Different Widths, Choose To Add The Bracket Expansion Axis. The Automatic Bracket Can Rotate Up And Down, Left And Right Automatically According To The Scope Of The Workpiece. The Laser Beam Can Be Adjusted Freely Accordingly To Ensure That It Can Adapt To The Lower Die With Different Widths And Heights. Generally, It Can Cover The Lower Die Within The V6-V180 Range.
The Sensor Accuracy Is Within ± 0.1 ° And The Angle Accuracy Is Within ± 0.3 °.
The Workpiece Can Be Detected Within The Angle Range Of 30 ° - 180 °.
When The Bending Workpiece Is Long, Two Pairs Of Products, Namely Four Sensors, Can Be Selected For Correction And Compensation.
Measurement Accuracy
The Accuracy Error Of The Sensor Is Within ± 0.1 °. However, It Is Affected By The Working Conditions, Especially The Mold And Sheet Batch. Generally, The Bending Accuracy Can Meet ± 0.3 °
Bending Accuracy Display
