3.3Description of the system characteristics

3.3.1 Design standard

The equipment strictly is accordance with the EU CE standardEN13155:2003, To carry on the design on based of US ASME(Mechanical engineering association)B30-20-2006standard and Germany UVV18standard,Main design index is higher than the above standard.

(1)Safety factor:Main design is greater than 2.0,Vacuum system pressure value for calculation is 60%,The actual peak pressure can reach 85% degrees,Set aside about 40% degrees.

(2)Board of  overhang

To calculated according to the board overhang. (Minimum thickness)

Minimum thickness of plate: 3mm

Max. overhangL=1016mm

See below schematic diagram.

 

Remarks: If the board handling amount of overhang beyond the maximum allowable value,Can cause irreversible permanent deformation of board.

 

3.3.2 Suction forcecalculation :

Dia.230mm.

Single pad max.suction force in theory on horizontal=Effective surface (Theory of area*factor)* calculated pressure(0.6bar).=(0.115*0.115*3.14)*0.6*10000=249N,Approx249Kgf.

According to the double safety factor,Actually allow the suction pad249/2=124kgf,  number of 6 total suction force 700kgf.

 

Note: The holding force mentioned above is calculate on 60% vacuum pressure, maximum vacuum degreeof the system will be up to 85% above in a normal working condition.

3.4Main Spare parts list and functional description.

The device includes the following main components:

1,Vacuum pump:

To choose Germanybrand of Becker,Oilless, air cooling, rotary vanes vacuum pump, bleed air rate 8m³/h,  and the max. Vacuum degree up to 85%;to save energy,  small and light,  maintenance-free, etc

Oil free air cooling type rotary vane vacuum pump, connected to 220V,, Three-phase power can produce vacuum, As a core part of vacuum system,  The highest vacuum degree 85%;

2,Vacuum pad:

To suction the work piece surface, Rubber in contact with the workpiece, ensure that won't cause damage to the workpiece surface.

3,Vacuum filter:

To eliminate the dust and particles in the air flow, ensure the lifetime of the vacuum pump;

4,Vacuum gauge:

To show the vacuum level to the operator, Provide security;

5,Vacuum pressure switch:

Pump-film type,When insufficient vacuum pressure, To give electrical signal to alarm system.

6, Manual slide valve:

To switch off the access of vacuum pump and suction pads between the air flow, Safety locks ,prevent accidental operation.

7,Vacuum non-return valve:

When the system power failure occurs, automatically shut off the vacuum pump and air channel, Lock the vacuum energyofvacuum tank.Provide enough pressure holding time, ensure the workpiece will not falling insuddenly.

8, Manual Ball Valve:

To manually open or close vacuum pump and suction pads pathway, convenient maintenance.

9, Alarm indicator lamp:

When the suction force of a single set of suction pads is insufficient, The corresponding indicator light alarm.
