VisionLine for marking

Modular sensor technology for every step in the marking process

Marking with process reliability

– from precise positioning to verified marking

VisionLine is a modular sensor system that supports every step of the marking process. It detects the component position, corrects deviations in real time , and checks codes and text for readability, contrast, and completeness. Depending on the component size , it uses high-resolution cameras for very small parts or multi-camera systems for large workpieces. This reduces rework and inspection costs. All measured values are documented – full traceability for audits and compliance. The modules are designed to work with TRUMPF lasers and optics and operate without an external interface.

Position recognition

VisionLine Detect

Feature recognition for simple geometries
  • Automatically detects workpiece positions based on defined features such as bends, circles, or holes from a feature library 

  • Automatically aligns the laser with the workpiece, even if the parts are slightly misaligned or twisted 

  • Optional AI filter for reliable detection even in challenging component, lighting, or contrast conditions 

VisionLine Model

Geometric recognition of entire, pre-programmed workpieces  
  • Teach the system the entire workpiece once, and it will then automatically detect its position and orientation

  • Automatically compensates for variations in position and height by adjusting the focus position – even if the parts are positioned differently in the marking area each time

  • Captures multiple components in a single shot and marks only those it can reliably detect

Marking bone plates

Marking bone plates

Codes and markings on bone plates must be precisely positioned and permanently legible – this is a requirement for meeting the traceability requirements of the medical technology industry. Different component geometries make it difficult to position the markings consistently.

VisionLine Model automatically detects the geometry and corrects the marking position in real time. Codes and text are consistently applied to the specified location – reproducible quality even at high throughput.

Quality

VisionLine OCR

Detection and quality assessment of text and numbers
  • Automatically reads selected text and numbers, including both system fonts and machine fonts  

  • Evaluates the quality of the markings, such as contrast and character sharpness

  • Compares the read data with the database and, if desired, documents it along with its content and quality assessment

  • Uses the read data directly in the marking process, for example, for sequential serial numbers

VisionLine OCR in use

Reliable detection of cursive script

Reliable detection of cursive script

Intricate cursive script with intertwined letters and varying line thicknesses must be clearly legible. At the same time, different materials (metal, plastic, leather, ceramic) require specific marking parameters. Illegible or incorrect markings result in rejects and rework.

VisionLine OCR uses optical character recognition to verify each character after it has been marked. The markings are compared against your specifications – illegible, incomplete, or incorrect markings are reliably detected. This helps to avoid rejects and rework.

VisionLine Code

Detection and quality assessment of 1D and 2D codes
  • Automatically reads marked barcodes, Data Matrix codes, and QR codes

  • Checks each code for contrast, modulation, and uniformity in accordance with ISO 15416, 15415, and 29158, and assigns a quality rating

  • Documents each result to verify that the marking complies with the specifications 

VisionLine Code in use

Marking surgical instruments

Marking surgical instruments

Codes on delicate surgical instruments (tweezers, scalpels, forceps) must be reliably legible despite their small size. Different surface materials (stainless steel, titanium, special alloys) make precise marking even more difficult.

VisionLine Code reads every marking after the process – even intricate 1D and 2D codes. The system checks the content for legibility and accuracy and immediately detects incorrect or inadequate markings. This helps to maintain a traceable record and avoid defective instruments.

Marking watch components

Marking watch components

Data Matrix and QR codes containing serial numbers and authentication data must be precisely marked on very small surfaces and remain permanently legible. Reliably inspecting these intricate codes is a particular challenge in the watch industry.

After laser marking, VisionLine checks the legibility and content of each code. Incorrect or inadequate markings are immediately detected and documented. This enables you to implement reliable quality assurance that satisfies the high standards of the Swiss watch industry.

What makes VisionLine special

– the special features at a glance
Always correctly positioned – even when the component position changes

VisionLine captures the workpiece in real time using the same optics as the laser (coaxial camera alignment). Because the camera and the laser are aligned in the same direction, there is no misalignment between the camera image and the marking point. If the component deviates from the programmed position, the system detects the deviation and compensates for it before marking begins. This ensures that the marking is accurate even if there are tolerances in the fixture or if the workpiece has shifted slightly.

Faster setup – even without precise alignment

An additional side camera captures the entire working range and detects workpieces even before the marking process begins. You can therefore place the parts anywhere without having to position them precisely – VisionLine locates each one and marks it at the designated spot. This reduces the need for fixtures and setup time, especially when switching between series.

Automatically in focus – no manual readjustment required

Two autofocus systems operate in parallel. The laser autofocus measures the distance to the part surface and automatically adjusts the working distance, regardless of how high the part is at that point. The camera's autofocus keeps the image in focus at all times, allowing VisionLine to reliably detect features and codes. Even stepped or curved components can be marked this way without the need for readjustment.

Reliable detection – even in challenging lighting conditions

Four light sources illuminate the workpiece evenly, independent of the ambient lighting. Distracting reflections and shadows don't even appear in the camera image in the first place. This allows VisionLine to reliably detect bends, positions, and other features even on shiny or heavily structured surfaces.
