HDY-2.8M dual-car PCB transfer machine is a high-efficiency parallel shuttle transmission equipment specially developed for long-distance docking and cross-line PCB transfer of SMT automated production lines. Adopting a heavy-duty thickened bent sheet metal frame, the equipment features stable structure, strong load-bearing capacity and long-term operational stability in high-frequency mass production scenarios. The guide rail is made of special industrial aluminum profile, with a single rail manual adjustment range of 50~350mm, compatible with most mainstream standard PCBs on the market.

The whole machine adopts dual stepper motor independent drive, realizing precise control of track conveying and horizontal translation respectively. Equipped with imported timing belt and high-precision linear guide transmission mechanism, it achieves smooth and low-noise PCB transfer, with the fastest front board output speed up to 14S/PCS, effectively improving SMT line production efficiency. The standard working height is 900±20mm, perfectly matching the installation height of mainstream SMT equipment such as solder paste printers, chip mounters and reflow ovens.

In terms of control configuration, the machine is equipped with Inovance PLC programmable controller and humanized touch screen operation panel, with simple operation and stable program operation. The complete electrical system adopts Mean Well power supply and Omron relays, equipped with a complete set of control box, ensuring low failure rate and high durability for 24-hour continuous production.

1. Reinforced Thickened Frame: Adopts thickened bent sheet metal frame, which is more rigid and anti-deformation than ordinary thin sheet metal transfer machines, suitable for long-span 2800mm wide line body operation.
2. Dual Independent Stepper Drive: Track conveying and horizontal translation adopt separate stepper motors, with higher transmission accuracy and more stable beat control than single-motor integrated drive of peers.
3. Imported Transmission Configuration: Matches imported timing belt + precision linear guide, effectively avoiding board shaking and deviation, with faster transfer speed (14S/PCS) and better stability than ordinary belt transmission models.
4. Wide Compatibility Rail Design: 50~350mm manual adjustable aluminum rail, flexible adaptation to various PCB specifications, strong production compatibility and low line transformation cost.
5. High-standard Electrical Accessories: Standard Inovance PLC, Mean Well power supply and Omron relays, industrial-grade stable configuration, lower failure rate and longer service life than generic domestic accessories.
6. Long-span Stable Operation: Optimized structural design for 2.8m ultra-wide line body, solving the jitter and unsmooth transmission problems of ordinary transfer machines in long-distance docking.
7. Intuitive Human-computer Interaction: Equipped with independent touch screen panel, convenient parameter adjustment, operation monitoring and fault query, saving debugging time.
8. Industrial Durability: Professional industrial aluminum rail and anti-wear transmission structure, adapting to long-term uninterrupted SMT mass production, reducing later maintenance cost.

This HDY-2.8M dual-car parallel transfer machine is widely used in the connection and cross-line transfer of full SMT assembly lines. It is perfectly compatible with mainstream SMT equipment including SMT chip mounters, solder paste printers, reflow ovens, AOI inspection machines and PCB loaders/unloaders. It is mainly applicable to the production lines of consumer electronics, automotive PCBA, communication circuit boards, medical electronic boards and industrial control motherboards, and is especially suitable for long-span line body docking and beat matching in large-scale SMT automated production workshops.
