3.Operating instructions

A Preparation before operation

1)Check the electric box has loose line and short circuit conditions or not;
check the transmission part if there is any Unidentified thing stuck;

3)check the preheating box have flammable objects and debris or not;

4)check the air pressure have 4 to 7 kg/cm or not

5)check whether the power supply three phase five wire, ground wire of resistance under 10R;

6)check whether the spray transverse cylinder flexible;

7) check the flux box if there is flux or not;

8)check whether the spray filter through content;

B The machine hardware installation and instructions

1):Install import board Conveyor

Take the import board conveyor to install docking, screw can be adjusted up and down the balance.


Note: 1.Conveyor guide high and low level adjustment

2.Conveyor guide vertical level adjustment

3.Conveyor guide right and left adjustment

2):Must let import conveyor chain plane into a straight line with claw.



 

3):Install the oil-water separator

a.Oil-water separator is installed on the side of board import hole where has a small hole (The above has two cross screws )


 

b.Plug in pipe ,installation is completed


 

4):Molten tin stove installation


a, the tin stove frame is installed in the position of tin stove in and out .

b.The tin should be distributed on the sides and bottom of the tin stove.(In order to avoid empty tin stove burning lead to deformation )


c.Open a tin furnace for heating temperature

d.In the process of heating, when tin melting on both sides of the tin stove,must continue to add tin. Until it is full .

e.Tin surface should be the plane in 5 mm different with tin stove . As the best state.

5):Following figure


Note: 1.The first wave control speeder

2.The second wave control speeder

3.Chain height adjustment


Note: 1.Adjust the size of air demand of rosin spraying

2.Adjust the size of air demand of rosin spraying moving orbit

1) Monitoring menu: boot monitor will show as below

Touch screen display and flashing automatically ;


2) According to company name to the main menu. Any touch screen to enter the next menu.


3) This grapics for operating

a:In this picture is able to transport, spray, wave, washing, tin stove,manual/

automatically control one by one.

b:Tin stove is automatically start when turn on PC

c.Production counter starts counting from the first piece of PCB.

d:Transportation speed display 。”U” type optical eye not shown without detection.(” U “light eyes in export of equipment )

e:”Settings”button to enter the next menu.


 

4) This menu is the main menu of setting spray distance, wave distance, peak time.

a: Spraying distance, setting value refers to the distance from light eyes into the sprayer.

b:wave distance, setting value refers to the distance from light eyes into the tin stove.

c:wave time, setting value refers to the automatic state the time of the wave crest.
(note: the value set are analog value, not as the actual distance and time.)

5) In the control panel of preheating and tin stove temperature control table

a: SV : Set value,
b: PV : easurements value.
c: OUT for SSR output signals
d: AT : PID automatic calculation indicator
e: ALM1 : Alarm 1 light
f: ALM2 : Alarm 2 lights
g: SET keys function keys.
h: Another three arrow button is used to set value.

5.Maintenence

1), Check whether the transmission has lubrication and smooth;

2), Check the transmission system fixed position whether there is loose;

3), Check whether the chain claw has a deformed shape;

4), Check whether the preheating box with debris, dust, and the stagnational flux ,clean them up;

5), Check the filter and remove flux cover and clean residue excess;

6), Check the sprayer spray atomization system is uniform or not, transverse cylinder smooth or not;

7), Check the tin oxide black powder, slag is too much or not;

8), Check whether the plane wave soldering tin is stable, thoroughly clean again per 400h.

 

 

6.Attention

1), Never put flux in a preheated box and tin stove

2), Never will drip flux on machinery and equipment with high temperature and electric box;

3), Absolutely can’t unlimited heating when without adding tin in tin stove;

4), Grounding line must be reliable;

5), Tin stove temperature optimal setting temperature to 260 ± 5 degrees;

6),The best transmission speed : 0.8-1.3 m/min.

7),Best preheating temperature, PCB welding side temperature :100±10 degrees.
