SMT (Surface Mount Technology) peripheral equipment covers multiple aspects according to technical classification, including board loading and unloading equipment, transmission and connection equipment, buffering and testing equipment, and other auxiliary equipment. These equipment play an important role in the SMT production line and together constitute an efficient and automated production system.

1. Loading and unloading equipment

Board loading machine (board feeding machine)

Technical features: By receiving the board-required signal from the lower computer, the PCB is automatically sent to the SMT placement machine.

Classification: Including micro board feeder, stacked board feeder (stack board machine), fully automatic board loading machine, etc.

Function: Effectively save labor costs and improve production line efficiency.

Unloading machine (receiving machine)

Technical features: By receiving the signal from the host computer, the PCB completed on the SMT placement machine is placed into the material frame.

Classification: Including fully automatic board unloading machine, L-type board collecting machine, stacking board collecting machine, etc.

Function: Realize automatic board collecting function to save labor costs.

2. Transmission and connection equipment

Connection desk

Technical features: used for connection between SMT production lines, and can also be used for manual insertion of PCB buffer, auxiliary inspection, testing or electronic components.

Classification: including single-track docking station, double-track docking station, telescopic docking station, etc.

Function: Provides flexibility and scalability of SMT production lines to meet various production needs.

Parallel transfer machine

Technical features: used to connect SMT single-track equipment with dual-track equipment, realizing two-in-one, three-in-one, and one-in-two functions.

Function: Mainly used for connecting single-track placement machines with dual-track reflow soldering, saving manpower, material resources and electricity costs.

3. Cache and detection equipment

Multi-function register

Technical features: used for AOI/SPI waiting for NG PCBs in SMT production lines.

Function: According to the temporary storage and maintenance of AOI/SPI waiting for inspection equipment to give NG/OK signals, handle defective products and improve the efficiency and quality of the production line.

NG Buffer Conveyor

Technical features: Also used for PCB buffering of AOI/SPI waiting for NG inspection equipment.

Function: Quickly process defective products to avoid affecting subsequent processes and improve the efficiency and quality stability of the production line.

Temporary storage machine (board storage machine)

Technical features: Used to temporarily buffer slower equipment on the SMT production line.

Function: Prevent damage to the stacked boards and improve the efficiency and quality stability of the SMT production line.

4. Other auxiliary equipment

Flipping machine

Technical features: Automatic double-sided board flipping for SMT production line.

Function: By flipping the PCB 180 degrees, negative operation can be achieved, saving manpower.

NG/OK board collecting machine

Technical features: After being used in AOI inspection equipment, NG and OK plates are stored separately according to the NG/OK signal of the inspection equipment given by AOI.

Function: Intelligent plate collection, saving manpower, quickly processing defective products, and avoiding affecting subsequent processes.

Suction machine

Technical features: Through four systems including lifting platform, vacuum adsorption system, translation transmission and track transmission, the stacked bare boards are transferred to the connecting track through vacuum adsorption.

Function: Realize the automatic board loading function and improve the efficiency of the SMT production line.

Suction integrated board loading machine

Technical features: Combines the functions of automatic board loading machine and board suction machine.

Function: The two board loading modes can be switched at will, which is convenient and fast, and improves the flexibility of the production line.
