Structure of UV Laser Coding Machine

The Industrial UV Laser Coding Machine consists of several core components that work together to achieve stable and accurate coding during production. The configuration may vary according to application requirements, production speed, and installation conditions, but the overall structure typically includes a laser source, marking head, control system, supporting structure, and product detection system.

 

UV Laser Source

The UV laser source is the core component of the machine. It generates the laser beam used to create permanent markings on product surfaces and packaging materials. Depending on the application, different laser power configurations can be selected to match the required coding content, production speed, and packaging material characteristics.

 

Marking Head

The marking head directs the laser beam onto the product surface and performs the coding operation. It is responsible for producing text, dates, batch numbers, QR codes, barcodes, logos, and other identification information. The marking head can be positioned according to product dimensions and the required coding location.

 

Touch Screen Control System

The control system allows operators to create, edit, and manage coding content.
