IV. Core Features of the Equipment
This equipment adopts a sheet metal and aluminum alloy enclosed body structure, which is sturdy and robust, with a high protection level, ensuring long-term safe and stable operation. It is equipped with a stepper motor and ball screw drive, ensuring smooth stepping and lifting of the frame with high repeatability. The equipment uses a PLC intelligent control system with a touch-screen interface and built-in automatic fault diagnosis function, making human-machine interaction simple and convenient. The lifting platform supports five-level pitch adjustment, adaptable to PCB board processing of different thicknesses and processes; it is equipped with a three-point pneumatic clamping positioning structure, combined with a hand-cranked screw width adjustment mechanism, ensuring no frame positioning deviation. The equipment features a pusher protection structure, effectively preventing board breakage due to compression and reducing production process losses. It comes standard with an industry-standard SMEMA communication interface, ensuring seamless compatibility with mainstream SMT production equipment, offering enhanced versatility and adaptability.

V. Application Scenarios

- Reflow Soldering Back-End Process: Connects to the reflow oven's discharge end, automatically collecting high-temperature PCBs and neatly stacking them, replacing manual board picking, avoiding the risks of high-temperature operations, and improving production cleanliness.

- Multi-Process Mid-Stage Storage: Suitable for the back-end of multiple processes such as pattern transfer, etching, and solder masking, automatically collecting processed boards to ensure smooth transitions between processes and achieve uninterrupted production on the assembly line.

- DIP Component Insertion Production Line: Located at the end of the component insertion process, automatically collecting completed circuit boards and neatly storing them in a material rack, preparing them for subsequent soldering, testing, and packaging processes.

6. Differences between General Product Features and Core Advantages

1. General Features

Industry-standard PCB receiving machines all possess basic functions such as automatic PCB receiving, material frame circulation switching, production line integration, and pneumatic transmission. Basic parameters such as power supply, air pressure, and frame changing time are universally applicable, ensuring stable and consistent basic receiving performance.

2. Core Advantages

- L-shaped corner structure: Unlike inline models, the corner-exit design adapts to workshop corners and narrow workstations, flexibly optimizing production line layout.

- Dual specifications available: 250S/330S models cover small to medium-sized PCBs, suitable for the production of various electronic products.

- Multiple protection structures: Audible and visual alarms + fault self-diagnosis + push-board protection significantly reduce board scrap rates, suitable for precision circuit board production.

- Compact and lightweight: The machine has a compact footprint and is lightweight, allowing for flexible placement and greater adaptability to small to medium-sized workshops.
