Precision Revolution in Surface Carving DFC dynamic focus control module

0.1mm level focus tracking, allowing any curved surface to be carved and formed in one go

Overcome the problem of defocusing in micro curved/step surface carving, and adapt to complex shapes such as cylindrical water bottles and 3D phone cases

Focus Accuracy

The fatal weakness of curved carving - why is traditional focusing inadequate

Scene pain point restoration

When carving cylindrical water bottles, fixed focal length causes blurry patterns on the upper and lower edges; 3D phone case step surface carving requires focusing in three stages, which is inefficient
Fixed focal length cannot adapt to surface undulations
The spot size has increased from 0.05mm to 0.2mm (accuracy has decreased by 75%)

Batch focusing leads to increased working hours

Process of Focus Offset in Surface Carving

A
Focus state
Clear light spot and precise carving
B
Slight defocusing
The edges are starting to blur
C
Serious defocusing
The pattern is blurry and indistinct

Five dimensional dynamic focusing system - millisecond level closed-loop control from distance measurement to execution

① Real time distance measurement layer

  • ToF laser sensor: 2000Hz sampling frequency
  • 0.1mm ranging accuracy
  • High speed ADC conversion: data transmission delay

From Process Difficulties to Commercial Gains - DFC Reshaping the Economic Model of Surface Carving

Case 1: Curved relief of wooden crafts

pain spot
The curved walnut ornament needs to be focused three times, with a scrap rate of 15% and a single piece time of 45 minutes
Solution
The ToF module scans the surface in real-time, and the motor drives the lens to move up and down by 1.2mm (convex)/0.8mm (concave), maintaining a focus error of ± 0.1mm
benefit
Once formed, the uniformity of pattern depth is increased by 40%; Reduced working hours to 28 minutes, increased monthly production capacity by 60 pieces, and increased income by 12000 yuan/month
45 minutes
Time consumption per item before use

Single piece time consumption after use

Case 2: TPU phone case oblique step carving

pain spot
The 2mm step drop results in varying carving depths, requiring manual adjustment of power density
Solution
200 object surface samples per second, 0.3mm focal length switching completed within 0.5 seconds, synchronized adjustment of laser power
benefit
The customized unit price has increased from 35 yuan to 58 yuan, and the daily order volume has increased from 12 pieces to 25 pieces; Monthly profit increased by 4200 yuan, equipment investment recovered in 6 months
