L-shaped PCB automatic board collecting machine, SMT production line board receiving equipment

L-Type Automatic PCB Receiving Machine - SMT Production Line Unloading and Receiving Equipment

I. Product Introduction

The L-type automatic PCB receiving machine, also known as a board unloading machine or PCB receiving machine, is used at the back end of an entire SMT and DIP production line. It is available in 250S and 330S sizes to accommodate PCBs of different sizes. The machine adopts a compact L-shaped layout with alternating double material frames. It automatically receives finished boards after reflow soldering, through-hole assembly, and PCB manufacturing processes, eliminating manual board handling and preventing high-temperature burns, board scratches, and component damage from compression. This improves the automation continuity of the production line and reduces labor and scrap costs.

Table 2. Dual Specification Dimension Comparison Table

Model Specifications - Compatible PCB Size Range - Matching Piece Frame Dimensions - Overall Machine Length, Width, and Height Dimensions - Applicable Scenarios
250S - Board Width 50-250mm - Board length ≤350mm - 355*320*563mm - 1000*1000*1680mm - Small and medium-sized PCB surface mount and small board insertion line receiving

330S - Board width 50-330mm - Board length ≤450mm - 460*400*563mm - 1200*1200*1680mm - Large-size circuit boards and multilayer boards end-of-process receiving

III. Equipment Features

1. Standard Configuration

1. Stable PLC electrical control system, supporting 24/7 uninterrupted production line operation with low failure rate;

2. Standard SMEMA communication, seamlessly connecting to reflow soldering, wave soldering, testing equipment, and insertion production lines;

3. Dual fault alarms (audio-visual + screen pop-up), rapid anomaly alerts, shortening downtime for maintenance.

2. Core Standard Configuration

1. Fully enclosed sheet metal aluminum alloy unibody design, dustproof and anti-pinch, with a safety protection level higher than ordinary open models;

2. Stepper motor paired with precision ball screw drives the material frame lifting, ensuring smooth and vibration-free operation and preventing deformation of thin sheets;

3. Three-point pneumatic positioning and clamping mechanism, with adjustable track width via hand crank, ensuring the material frame does not shift and sheets are stacked neatly;

4. Built-in buffer push plate protection structure, buffering pushing force, preventing component collisions and sheet surface damage, reducing scrap;

5. Touch screen with built-in automatic fault diagnosis program, one-button parameter adjustment, allowing even novice operators to quickly get started.

IV. Application Scenarios

1. Reflow Oven Outlet: Automatically collects high-temperature PCBs after soldering, replacing manual handling, avoiding burns and scratches, and stabilizing finished product yield;

2. Mid-Process of PCB Manufacturing: Automatically collects semi-finished products at the end of etching, solder mask, and circuit forming processes, ensuring uninterrupted multi-process flow;

3. End of DIP Assembly Line: Automatically collects circuit boards with inserted components, neatly storing them in the feed frame for easy transfer to wave soldering and functional testing stations.
