3D Scanning Automatic Spray Machine

Model: SL-TSP-W-3D

Load the workpiece onto either rotating table and start with its actual geometry, not a preset outline. The external HIKROBOT scanner captures contours, dimensions, position, and internal openings, then transfers the data into an automatically generated spray path. Five-axis motion follows the scanned shape while the second table remains available for workpiece changeover.

Application Materials:

  • Wood, MDF, Glass, Ceramics
  • Metal, Plastic, Special material, etc.

Application Coatings:

  • PU, PE, Water-based paint, Special paint, etc.

3D Scanning Automatic Spray Machine for Irregular Parts

The 3D scanning automatic spray machine begins with workpiece recognition before coating starts. HIKROBOT vision technology captures the outer contour, dimensions, position, and internal openings of each part. The control system converts the scanned data into processing information, allowing different product shapes to enter the same spraying workflow without manually rebuilding every spray path.

The automatic spraying machine adapts the coating path according to the actual geometry of the workpiece. This makes it suitable for parts with changing profiles, irregular surfaces, and complex structures.

Scan First, Then Build The Spray Path

After scanning is completed, the touchscreen displays the detected shape and related processing information. The generated data becomes the reference for five-axis spraying movement.

The system supports:

  • Rectangular and polygonal parts
  • Curved or irregular outlines
  • Components with internal openings
  • Products with thicker edges or shaped profiles
  • Repeated parts using saved graphics and batch files

Different product geometries can run through the same machine workflow without depending on one permanently fixed trajectory. This flexibility allows production changes without rebuilding spray programs from the beginning.

Keep One Table Spraying While The Other Is Ready For Changeover

Two rotating and turnover tables separate spraying and preparation operations. While one table remains inside the spraying area, the second table provides space for loading, unloading, or preparing the next workpiece.

Motor-driven indexing beneath each platform changes the workpiece orientation relative to the spray head. The five-axis mechanism then reaches additional edges and surfaces by adjusting the spray direction according to the part position.

This working method keeps the spraying process continuous by reducing downtime during workpiece changeover.

Follow The Scanned Shape With Five-Axis Motion

Servo-controlled axes move the spray head through linear travel and angular adjustment according to the scanned geometry. A HIWIN linear guide supports long-axis movement, while the integrated spray-head assembly changes position and angle around shaped surfaces and thicker edges.

The automatic spray machine keeps the spray head aligned with the workpiece as the profile changes. Curved and irregular components can be processed without being limited to a flat-panel spraying pattern.

Apply Coating Through A GRACO Air-Mix System

The spraying system uses a GRACO medium-pressure Air-Mix gun with a 30:1 plunger pump. The spray gun combines coating pressure and atomizing air to create a controlled spray pattern during movement.

The pump maintains stable coating supply while the motion system controls spray direction and coverage. This coordination keeps material delivery synchronized with the programmed spraying path.

For a wider finishing process, the cell can operate together with other spray painting equipment and suitable drying processes. When production requires predefined spraying paths for repeated parts instead of automatic geometry recognition, a five-axis spray painting machine can support that workflow.

Automatic Spray Advantages

https://www.slcoating.com/wp-content/uploads/2026/04/3-50-efficiency-improvement.jpg

50% Efficiency Improvement

The new automatic spraying machine is equipped with two rotating workstations, enabling simultaneous loading/unloading of workpieces, 3D scanning, and automated spraying for non-stop operation. With an 8-hour workday, only 1 or 2 general workers are needed to produce 200-300 m² of high-quality products, delivering 50% higher efficiency than traditional manual spraying.
