AF-8500A Lid Placement, Tack and Seam Sealing System (formerly known as AF8500)
The Auto flow system is flexible enough to meet the ever-increasing demands of lid placement and seam-sealing applications as seen in the optoelectronic packaging industry. It can be configured either as a stand-alone unit or as part of a fully-integrated, automated manufacturing line. The computer-controlled precision tacking and seam-sealing mechanism is combined with a high-frequency inverter welding power supply and an optional high-resolution vision system to provide a robust and repeatable process. Auto flow can also be incorporated into an atmospheric enclosure to provide an integrated seam sealing glove box system, ensuring high-yield hermetic sealing results.
Key features AF-8500A Lid Placement, Tack and Seam Sealing System
- Programmable electrode force and weld current using a Windows®-based proprietary software
- Closed-loop high frequency inverter welding power supply features low sealing temperatures and power feedback, increasing yields and productivity
- Current control mode optimized for superior seam sealing results
- Position-based weld pulses ensure consistent spot spacing, optimized spot density at corners, reduced leaks, and elimination of acceleration/deceleration problems
- Auto-Trak™ software indexes electrodes ensuring extended electrode life and more even wear
- Electrode roll-back feature assists in electrode release from lightweight parts
- Automated lid alignment and placement option holds lid in place during tacking, preventing misalignment; easy-to-program vision software
- Automated magazine loader option loads from either top or bottom for a fully or semi-automated part handling system
