Full PCB Coverage Coating Machine(HTF-450A)

Introduction

1.Control System:
Equipped with an industrial computer and motion control card, operated via a 21-inch monitor with mouse and keyboard. Programming is simple and user-friendly.All programs can be stored and recalled for different PCB models. The system can automatically immerse the glue gun when no workpiece is present, preventing adhesive drying and clogging.

2.Machine Frame:
The frame is welded from thickened square tubes, ensuring strength and stability. The platform is made of stainless steel, offering high hardness, corrosion resistance, and easy cleaning. The surfaces are finished with electrostatic powder coating for a refined appearance.

3.Working Section:
The Y-axis motion platform is made of a linear guide, lead screw, and servo motor. Compared with stepper motor systems, it provides more stable and precise motion control. The dispensing valve is equipped with a Japan-made SMC slide cylinder for smooth and accurate operation. The machine uses dispensing guns and high-precision atomizing spray valves with adjustable spray width. A fine-tuning pressure regulator ensures stable air pressure and consistent glue output, enabling cleaner and more precise edges.

4.Conveying System:
Driven by a 57 stepper motor, the machine maintains stable conveying even when high-viscosity adhesive sticks to the chain. The self-developed conveyor aluminum profile is elegant and practical. It uses a chain-drive transport method, and the conveyor width is manually adjusted through a gear-driven mechanism for higher accuracy, with a range of 50–450 mm. The chain is a 5 mm stainless-steel chain with extended pins and baffle plates.
