Backdoor structure

Magnet with hand buckle detachable structure, maximum maintenance space

Top of the body

Set of explosion-proof lighting

Surface treatment

The whole machine is sprayed with computer white (the glass door frame is sky blue)

Spay Parts

Nozzle

The spray range is adjustable from 20 to 65mm, the nozzle height is adjustable from 50 to 80mm, and the maximum flow rate is 100ml/min.

Air system

Adopt imported filter, control valve and pipe joint, digital display air pressure. The spray air pipe adopts acid and alkali resistant, anti-corrosion SMC air pipe

Spray nozzle moving system

Stepping motor drive, PLC intelligent control, combined control with limit proximity switch and plate entrance light eye, automatic detection of induction spray according to the speed and width of the PCB.

Flux recovery system

The bottom of the nozzle is made of stainless steel bent and formed as a tray to contain waste water and flux, which can be taken out and cleaned at will

Flux exhaust filter system

Ventilation system: stainless steel screen frame and double-layer filter screen, using the characteristics of the fluid to filter and recover excess flux

Isolated wind curtain

Pneumatic air knife blows the excess flux during spraying into the recovery box to prevent the flux from entering the preheating zone. Ensure production safety.

Spray box structure

All stainless steel structure, easy to clean and maintain. High level of anti-corrosion and durable.

Preheating parts

Four-stage preheating zone

1800mm/4 sections of independent temperature control preheating zone can provide adequate preheating adjustment space, can preheat some relatively large PCBs, more complex products, adaptable low solid residue no-clean rosin flux; reduce PCB Board thermal shock, PCB board is heated evenly, which can improve production efficiency.

Temperature control method

Mitsubishi temperature acquisition module, PID temperature control is accurate and reliable, imported thermocouple detection system, with thermocouple abnormal alarm function.

Heating parts

Adopting Taiwan Taiwan Exhibition heating element, fast heating, long life, low thermal inertia; uniform heat in the temperature zone.

Preheating power

Total 22kw

Installation mode

The preheating system adopts a direct pull-out drawer type modular design, which is convenient for maintenance and cleaning.

Preheat box cover

It adopts arc streamline appearance design, and is filled with imported Cissr high-density rock wool to enhance heat preservation effect.

Conveyor parts

High-strength wear-resistant guide rail

SFG special aluminum guide rail uses high temperature and wear resistance, and the special thermal compensation anti-deformation telescopic structure ensures that the guide rail is not deformed and does not fall off the board

Rail parallelism

Two-point synchronous guide rail width adjustment device, high-precision screw rod width adjustment, the width adjustment accuracy is less than 0.2mm, 6-point support, so that the guide rails are parallel and consistent, there is no big or small head, the guide rail installation, do not need to cut off,
