Vision Laser Marker: Accurate Marking on Irregular and Multiple Parts

When parts are not neatly placed, or incoming material shifts, fixed marking drifts off. A vision laser marker photographs with a CCD, computes position and auto-compensates so every part is marked exactly where it should be.

Principle: see first, then mark

A CCD camera photographs the part; vision software reads feature points, edges or a QR code to get each part's real coordinate and angle, and the galvo compensates. It is millisecond-fast and needs no manual alignment.

Best-fit scenarios

Irregular parts (round bottles, curved surfaces, odd shapes), loose parts with shifting positions, multiple parts across a large area, and parts whose existing QR/feature must be read before marking related info. These are exactly where fixed markers fail.

Vision vs fixed

For tidy, fixed, high-volume parts, a fixed marker is cheaper and faster. But whenever incoming material varies or shapes are complex, the labour and scrap savings of vision far outweigh the price gap.

Typical industries

Electronics (PCB, connector alignment), hardware (loose nameplates), pharma (vials, boxes traceability), auto parts (curved parts) and gift customisation. Whenever manual alignment is costly or a miss is serious, choose vision.

Procurement Q&A

How do overseas buyers communicate and ship?

Open Mo–Su 08:00–23:00 (GMT+8) with English support. Reach us at +86 159 9995 5734, WhatsApp +86 190 9874 6815 or Laurie@laserdg.com. Machines are packed to export standards.

What is your engineering and supply capacity?

We have 3+ engineers, 7+ authorised patents and 5000+ units shipped. Standard parts like laser source and galvo are stocked long-term for predictable replenishment.

How is the price calculated?

Price depends on the model (UV / fiber / CO₂), power, laser-source brand (Raycus / JPT / IPG) and configuration (galvo, field lens, control software). Zhongyi Laser lists the exact laser-source and galvo models on the quote and in the contract, so the configuration is verifiable and easy to reorder or replace later.

What is the typical lead time?

Standard machines ship in 7 days; rush orders in 3–5 days; custom non-standard builds in 15–30 days. Before production we confirm drawings, process and sample results to avoid rework.

What about warranty and service?

18-month warranty on the machine. Core parts like the laser source and galvo are replaceable standard parts with long-term supply, so repairs and swaps are documented.

Can I test before buying?

Yes. Send a sample and we return a real test video within 24 hours and ship the part back. Key models get a 48-hour aging test, so you see the actual result on your own workpiece before deciding.

Can it mark irregular curved parts accurately?

Yes. Vision compensates in 2D after reading features; for large height differences add auto-focus Z-axis or 3D vision to keep focus consistent.

For many parts at once, is speed enough?

Vision and marking run in parallel — one shot, per-part compensation. Cycle time depends on galvo speed and part count; we size the solution to your line rate.

How much does vision affect accuracy?

It depends on camera resolution and lens; typical repeatability is around ±0.02–0.05mm, meeting most marking-alignment needs.
