Product details

The dual-head vision labeling machine is automated high-accuracy labeling equipment that replaces mechanical templates with machine vision and a single dispensing mechanism with two independent label-picking heads. After a workpiece enters the labeling station, industrial cameras first capture the workpiece’s datum features and the label outline, and the control system calculates the position and angle deviation between them and distributes the compensation to the motion mechanisms of the pick-and-place heads, so the label coincides with the intended position at the moment of application. The whole process is closed-loop across images, algorithms, and servo motion, no longer relying on the physical fit accuracy of fixtures and locating blocks. The two heads can act synchronously to apply 2 labels in one loading, doubling efficiency; they can also act independently by cycle to handle labels of different specifications and positions. This reduces investment in line-specific machines, and the unit can be used standalone or as a linked station in an automated line.

Key features

  • 1. Two cameras align independently with real-time deviation compensation: the two cameras separately capture the workpiece datum and the label edge, and the system calculates translation and rotation deviation from image coordinates and compensates before application. Even if the workpiece shifts slightly or changes angle during conveying, the label still lands in the set position.
  • 2. One loading, two labels applied. The two label-picking heads can apply 2 labels synchronously in a single loading, and the synchronous mode reduces secondary positioning.
  • 3. Recipe-based changeover compatible with mixed-specification lines: camera calibration parameters, application coordinates, pressure, and cycle are stored as recipes; at changeover, entering the product model recalls the corresponding parameters, suiting small-batch, multi-variety production organization.
  • 4. Handles reflective, transparent, and low-contrast surfaces: for metal, coated, transparent film, and dark surfaces, ring light, coaxial light, backlight, and polarization can be combined to restore feature contrast;
  • 5. Traceable data and open interfaces: the machine can integrate barcode and QR code reading, keeps labeling records by time, batch, and station, and connects to the manufacturing execution system via Ethernet or serial port, meeting product traceability and quality data review needs.
  • 6. Operator-friendly with complete safety protection: a color touch screen centrally presents recipe management, output statistics, and alarm information, with operating permissions graded by role; operating status and fault causes are shown instantly on the interface so shift teams can handle common faults themselves.
  • 7. Optional functions: 1. Defective product rejection — after application, a re-inspection camera checks label position, angle, edge lifting, and missing labels; products judged defective are automatically marked and separated at the rejection station, and the inspection result is recorded in the production log at the same time, preventing defective products from entering the next process. 2. Safety protection — the machine is fitted with a safety light curtain and interlocked guard doors;
