2. Industry Standard

Industrial-grade Safety Body: The enclosed sheet metal body combined with an aluminum alloy composite structure ensures a robust and stable design. It is dustproof, impact-resistant, and protected against workshop environmental interference, providing a high level of safety protection. Suitable for long-term, high-intensity mass production operations in factories, it extends the equipment's service life.

Precision Stepping Lifting System: Utilizes a stepper motor-driven ball screw structure to achieve precise stepping lifting of the material frame. It ensures uniform positioning, smooth and quiet operation, and eliminates offset and vibration, perfectly adapting to the production of medium to large-sized precision PCB boards, preventing board misalignment and jamming issues.

Intelligent Touch Control Operating System: Equipped with a high-definition touchscreen human-machine interface, it offers simple and intuitive operation. It features a built-in automatic fault diagnosis program, coupled with dual alarm prompts (audio-visual and screen), enabling rapid fault location and troubleshooting, reducing the barrier to manual maintenance.

High-Precision Positioning Adjustment: Employs a three-point upper and lower pneumatic clamping positioning structure, combined with a hand-cranked screw-based width adjustment mechanism. This ensures secure clamping and precise positioning of the material frame, adaptable to various specifications of medium to large-sized PCB boards, offering wider compatibility.

Dedicated Board Protection System: Featuring an independent pusher protection structure, it intelligently buffers the pushing force, effectively preventing problems such as squeezing, scratching, and cracking of medium to large-sized PCB boards, significantly reducing production waste and saving production costs.

Uninterrupted and High-Efficiency Mass Production: Dual material frames operate alternately, with a rapid automatic frame change every 20 seconds. The production line requires no downtime and allows for continuous material feeding, effectively improving the production cycle time and overall capacity of the entire production line.
