Inline Vacuum Potting Machine (HTD-550)

Introduction

• Control System:
Equipped with an industrial computer and motion control card, using a 21-inch display with mouse-and-keyboard operation. Programming is simple and user-friendly. The operating software is independently developed, making maintenance convenient. When editing dispensing programs, operators can select different mixing valves according to product requirements, and freely adjust Z-axis height based on PCB component height. All edited programs can be stored and recalled for different PCB boards. During spray operation without a workpiece, an anti-curing/dormant timer can be set. The machine will periodically perform a micro-purge to effectively prevent clogging of the dispenser gun and hose due to material drying.

• Machine Frame:
The base frame is welded from reinforced 60×60 mm square tubes with stress-relieved treatment, delivering excellent rigidity, hardness, and minimal thermal deformation. The working platform is precision-milled with a gantry milling machine to ensure the motion system operates on a stable and accurate platform. Other areas are covered with stainless steel to prevent conformal coating corrosion.The surfaces are finished with electrostatic powder coating for a refined appearance.

• Working Section:
The X, Y, and Z axes motion platform consists of slide rails, lead screws, and servo motors. The Z axis is equipped with a static/dynamic mixing valve, and a brushless motor drives the stirring rod, with a stirring ratio from 1:1 to 1:10.

• Conveying System:
Driven by a stepper motor with a 2.5 times speed chain conveyor, ensuring stable transport even with high-viscosity glue residue on the chain. The custom-developed aluminum conveyor structure is clean and aesthetically designed.

• Material Supply:
Provides automatic and precise ratio-mixing. Includes two or four SUS304 40L material tanks for continuous high-volume feeding. In a four-tank setup, the system automatically switches from A1/B1 to A2/B2 when levels reach the lower limit, enabling uninterrupted production. A and B materials are stored and supplied separately, supporting vacuum degassing. Vacuum tanks are placed on an independent platform with leveling feet for easy movement.

Features Summary

• 1. Supports dot, line, surface, arc, circle, and three-axis linkage functions to handle potting for irregular-shaped products.
• 2. Large-capacity storage without re-programming; The software features functions such as area array, translation, rotation operations, etc.
• 3. Adjustable glue volume，potting speed,potting time, and stop time; stable dispensing with no dripping.
• 4. Vacuum gauge with adjustable parameters; vacuum pump auto-stops when reaching upper limit.
• 5. Integrates mixing, dispensing, and trajectory potting with automatic loading/unloading.
• 6. On-demand metering enables mix-while-dispense, minimizing glue waste.
• 7. Built-in anti-curing timer; supports single-shot and continuous dispensing modes.
• 8. Independent control system unaffected by air pressure, preventing uneven flow, stringing, and bubbles.
• 9. Z-axis height adjustment accommodates components of various heights.
• 10. Material tanks equipped with level sensors and low-material alarms.
• 11. Optional German vacuum pump (165 m³/h)
