L-type PCB downloader​

Our company has been in operation for 11 years and will definitely be your best choice with guaranteed quality and fast delivery

Product Introduction – L-type PCB Downloader (Unloader)

The L-type PCB Downloader, also known as an L-type PCB Unloader, is used at the end of an SMT production line to automatically unload finished PCBs into storage magazines. Its L-shaped structure positions the magazine rack perpendicular to the conveyor, saving floor space and allowing easier magazine handling in compact environments.

Key Features

L-shaped magazine orientation: Optimizes floor layout by placing magazines at a 90-degree angle to the conveyor.
Fully automatic unloading: Transfers PCBs from the conveyor into magazine slots using a push-arm and lift system.
Touch screen operation: Intuitive HMI for setting operating modes, lift control, and diagnostics.
Programmable slot control: Supports empty-slot skip, adjustable unloading pitch, and full magazine detection.
SMEMA-compatible: Enables inline communication with AOI, reflow, or inspection equipment.
Safe and stable design: Aluminum frame with ESD-safe construction, emergency stop button, and protective covers.

LED light boards
Aluminum or fiberglass (FR4) boards
PCB size typically from 50 × 50 mm to 330 × 250 mm (customizable)

4. What are the compatible magazine sizes?

355 × 320 × 563 mm (standard)
390 × 320 × 570 mm (optional)
Custom magazine sizes are supported upon request

5. What are the main features?

L-shape magazine placement for compact line layout
Fully automatic PCB loading into magazines
Touch screen + PLC control system
Programmable slot pitch and skip-empty function
