Why this question comes up: the physics
A CCD vision marker calibrates the camera, then uses template matching to capture each part's actual coordinates and rotation theta, feeding both offset and angle into the marking coordinate system. Parts placed skewed or at random still receive a square mark, which removes the need for custom fixtures. Our vision platform locates to plus or minus 0.05 mm and can image once, locate every part on the tray and then mark continuously.
The answer and the process detail
Inspection and marking can be combined. The vision system applies defined rules - dimensions, presence of features, missing material - skips any part that fails, and can output a signal to a reject mechanism. The precondition is that the criteria are explicit and measurable; vague cosmetic defects have to be trained on samples and the false-reject rate agreed. Send defective samples along with good ones and we will verify the recognition rate on real faults.
How to set it up and verify it
Recognition runs in milliseconds and is rarely the bottleneck - marking time and load-unload cycle dominate. There is no fixed calendar interval for calibration: recalibrate after every changeover or any adjustment to camera or fixture, and in normal production check with a standard part once per shift or week to confirm deviation stays within plus or minus 0.05 mm. Reflective, transparent or feature-poor parts need the grip strategy agreed first, and heavy overlap calls for singulation on the feed side.
Selection and delivery
It suits random part presentation, mixed-model lines and cases where defects must be detected and skipped automatically. Vision can also combine inspection with marking: apply rules on dimensions or features, skip anything that fails and output a reject signal. The criteria must be measurable - vague cosmetic defects have to be trained on samples and the false-reject rate agreed.

Procurement Q&A
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.
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.
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.

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.
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.

Yes. One image is taken and the vision system solves the coordinates of every part on the tray, then the head marks them in sequence - much faster than aligning each piece. Accuracy depends on camera resolution and calibration quality; our vision platform locates to plus or minus 0.05 mm. If parts sit at different heights, confirm the depth of field covers them, or image the tray in zones.
Yes. The vision system classifies by template matching or measured features and passes the result to the control software, which loads the matching marking file - no operator intervention. The precondition is a measurable difference between variants; parts that look too similar need an added fiducial or barcode identification. Our vision platform supports multi-template management and custom decision logic.
