Unwind / Rewind:
• uses air shafts, assures concentricity and non-slip of material roll (stable rolling), fast roll loading/unloading, supplied with choice 3” air shafts (standard) or with 6” air shaft sleeve (optional)
Web flow:
• servo-driven rolling, working with structural EPC tracking system; servo tensioning control
Screen printer:
• ATMA 4-post “OE” precision version module, integrating all function sections:
• Printer section: digital-controlled servo motor driven 4-post lift, to: print level(off-contact, digitally set, air locking - against heavy print pressure) / standby level / cleaning level.
• Substrate base table section: with dynamical On/Off and volume-adjustable vacuum (to fix material); servo-driven 4-post up/down(not air-borne concept)-web pass without scratch);
• Screen section: Adjustments: holder arm positioning / air-locking, pneumatic screen holder levels, holder arms(screen) leveling, supplementary positioning by screws, screen frame XXYY digital-servo driven fine-adjustments; servo-driven gradual peel-up of screen during print stroke (to prevent sticking, stroke/ speed adjustable; servo-driven digital-set stroke length & start/stop points, automatically averaged to print stroke)
• Squeegee section: servo-driven left-right stroke, coordinated to squeegee / flood coateralternative down for printing / flood coating (relative to screen-substrate in fixed position; Squeegee & flood coater both up to clear off screen); Adjustment: digital-set stroke start/stop points & speed, skew angle (to overcome print skips at corners); Squeegee / flood coater adjustments: manual mounting positioning, set-down level(depths), leveling(print evenness), inclination angle(deposit thickness), up/down speeds, digital-set pneumatic driven constant print pressure...
Printing / flood coating:
• servo-driven, stroke / speed digital-controlled, solid drive torque, super stable run over entire stroke, fault free.
Printing / flood coating pressure:
• digital-set constant pressure systems, each providing 3~62 kgf pressure parameter setting in HMI.
Camera visual automatic screen-substrate alignment:
• optional 4 cameras (2 as standard) cameras and servo-driven screen frame move auto-alignment system, achieving precisely registered printing.
High flatness table:
• made of thick aluminum alloy board, fine smooth processed and hard anodized(scratch-resistant), achieving flatness at ±0.02mm, realizes fine line/dot printing. Servo-driven 4-post down during printing / material web pass.
Control / operation system:
• high-level industrial computer integrated multiple controls, color LCD touch-operated HMI, provides multiple function parameter setting and immediate operation/monitoring, convenient for operation, complies to faultless demands in digitization, standardization and humanization.
Safety protection:
• with error diagnose/alert system, safety restoration, emergency-stop, beacon, safety dust covers(optional)..., considerate in safety protection.
Inspection / idle buffer sections:
• to provide ink idling (flow-out, antifoaming...) before work goes for drying, and hand-held camera shooting + magnified monitor display that assist operator eye inspection. (optional)
Various dryer type for choice (optional):
• according to material characteristics(thermal/tension durability), ink’s drying characteristics(energy, speed), and productivity demand(type, section length), normal types:
• IR + Hot Air drying: horizontal conveying type (with carrier belt, or pull-through type) Up/down routing type
• UV during: horizontal pull-through type (other types)
