Quality

At HuiDia, quality comes first and service is rooted in responsibility. The company has passed the ISO 9001:2015 Quality Management System Certification​ (Reg. No.: 06525Q02495R0S, covering the production of Surface Mount Technology (SMT) equipment, valid until September 2028), accredited with CNAS/IAF international mutual recognition marks.

We have established a standardized quality control system. From material selection, sheet-metal processing, and electrical assembly to final commissioning, all steps strictly follow the system requirements and multi-stage inspections. All SMT peripheral equipment — including PCB loaders, unloaders, conveyors, buffer machines, transfer machines, and non-standard customized devices — must pass running tests, signal interconnection tests, and safety checks before delivery, ensuring fast start-up and stable long-term operation on-site.

Combining systematic management with continuous innovation (including multiple utility patents), HuiDia delivers highly reliable, customizable, and easy-to-maintain automation equipment to electronics manufacturers worldwide.

Since 2017, HuiDia has kept “R&D as the moat, patents as the quality shield” in SMT automation peripherals. By 2026, the company has been granted 10+ utility model and design patents​ by the China National Intellectual Property Administration, covering core products such as SMT loaders/unloaders, conveyors, buffer machines, transfer machines, flip machines, vacuum pick-up units, board collectors and conformal coating machines.

Key patents include:

• PCB Board Feeder (CN223721974U)

• PCB Magazine Flip Machine (CN222877002U)

• Board Flipping Device (CN222877000U)

• Adjustable Clamping Mechanism for Transfer Machine (CN223619685U)

• Suction Fixture for Pick-up Machine (CN223687612U)

• Pushing Mechanism for Board Collector (CN224091121U)

• Dispensing Mechanism for Coating Machine (CN224025480U)

• Design patents for dual-track conveyor, buffer machine, stack feeder, etc.

• PCB Board Screening & Buffering Device (App. No.: 202522423337.X, accepted)

These patents target real production pains—board jamming, heavy manual intervention, tact-time mismatch, and high maintenance cost—through automatic loading/unloading, NG/OK screening & buffering, cross-line transfer, precise clamping, and clean coating. With patented structures plus standardized quality control, HuiDia delivers more stable, flexible and service-friendly SMT peripheral equipment and non-standard solutions.
