Summary of the Characteristics and Advantages of L-shaped PCB Board Unloader in SMT Equipment

I. Basic Definition and Working Principle of L-shaped PCB Board Unloader

The L-shaped PCB board unloader is a key piece of equipment in the SMT (Surface Mount Technology) production line, mainly used for collecting processed PCB boards and is typically installed at the end of the production line. Depending on their functions, they can be classified into standard models and NG/OK PCB board unloaders; based on their shapes, there are standard models and L-shaped PCB board unloaders.

The working principle is as follows:

The equipment is controlled by a microcomputer PLC control system and is equipped with two anti-static material frames. When the connection part sensor detects a board, the empty material frame enters the elevator from above. The elevator cylinder clamps the material frame, and the motor push plate device pushes the boards one by one from bottom to top into the material frame. The material frame moves down one grid at a time. When it is full of boards, the material frame conveyor belt will send out the full frame of PCB boards.

II. Technical Features and Structural Parameters of L-shaped Lower Plate Machine

1. Structural Design Features

The entire machine mainly consists of three parts: the front connection section, the middle body, and the right input and output frame.

The body adopts a sheet metal welding structure, with aluminum profiles for the input and output frame, and is surface-coated white.

It features an L-shaped special structure design, with a length of less than one meter, which can meet the requirements of almost all SMT production sites.

It occupies a small area, approximately 3 square meters, saving production space.

2. Core Performance Parameters

Control System: Equipped with a dedicated Siemens PLC control system.

Sensor: Omron brand.

Power Supply: Mingwei brand.

Input Voltage: 220V.

Feeding Form: PLC controlled.

The step distance for the material rack's lifting can be adjusted, and it can be set according to the height of the components on the PCB board.

III. Main Advantages of L-shaped Lowering Board Machine

1. Space Efficiency Advantage

Adopting an L-shaped design, with a length of less than one meter, it can meet the requirements of almost all SMT production sites.

It occupies a small area (about 3 square meters), saving 30-50% of space compared to traditional lowering board machines.

The front exit frame design ensures that the input and output frames do not interfere with each other.

2. Operational Performance Advantage

The electric push plate device is stable and controllable, with adjustable push plate speed, distance and force.

The conveyor belt speed is adjustable to adapt to different production rhythms.

It features a mature and simple operation interface, ensuring smooth operation of the loading and unloading adjustment track.

3. System Compatibility Advantage

It is equipped with standard short-circuit signals and can be connected to almost all electronic devices.

It is equipped with an SMEMA signal port and can be online automated connected with other equipment for operation.

It can be applied after reflow soldering, wave soldering, and various SMT machines.

4. Production Efficiency Advantage

The fully automatic board collection reduces the workload of personnel and improves production efficiency.

It uses brand components (such as Siemens PLC, Omron sensors, etc.) to ensure the stability and reliability of the equipment.

It operates stably and reliably, is convenient and fast, and helps improve the overall production line efficiency.
