7.7 Routing the Beam Delivery Optic
CAUTION: If damage to the conduit or optical connector is
suspected, stop using the QUBE Fiber Laser and contact SPI
Lasers immediately.
Failure to do so may result in exposure to harmful levels of
radiation.
Delivery fibers and optical connectors are precision parts.
Avoid contamination and mechanical stress when handling.
Avoid shocks and impacts on optical connectors
Avoid pulling, twisting and over-bending of the conduit
Beam delivery optics are less robust than electrical cables, although superficially they look
similar. If fibers are treated and handled as electrical cables, they will fail prematurely. Fiber
replacement can be both time-consuming and expensive.
Avoid kinking and twisting the conduit by unrolling the coil, rather than pulling it straight.
If the BDO is led through openings, the openings must be sufficiently large that the optical
connector with protector can be led through without applying any force.
In static applications (where BDO and process head do not move):
The BDO may be routed alongside power, water or control cables provided these do
not impose stresses or strains on the conduit.
The conduit must not be bent tighter than the minimum bend radius at any point along
the route. (Refer to Table 33.)
The maximum tensile loading should not be exceeded. (Refer to Table 33.)
The conduit should be supported at points along its length, at intervals no greater than
3m, to prevent gross movements under its own weight during the production
sequence.
At the support points, the conduit should be held using mechanical parts which prevent
bends tighter than the minimum bend radius and which do not apply a compressive
force on the conduit.
The external surface of the conduit should be prevented from rubbing or abrading at
support points or on any other parts in the workstation (e.g. jigs, fixtures, production
parts, workstation walls, floors, robot parts).
In dynamic applications (where BDO and process head move), additionally:
The BDO must be routed separately from power, water and control cables.
