Automatic parallel seam sealer

AF1250

Product Description

The Autoflow 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. Autoflow can also be incorporated into an atmospheric enclosure to provide an integrated seam sealing glovebox system, ensuring high yield hermetic sealing results.

Key Features

  • Lid Placement, Tack and Seam Sealing System – AF8500 & AF1250The AF series automated seam sealing systems provide users with the flexibility to meet the increasing demands of lid placement and seam sealing either as a stand-alone unit or as part of a fully integrated glovebox or automated manufacturing line. The computer-controlled precision tacking and seam-sealing mechanism is combined with a high frequency inverter power supply, and an optional high resolution vision system to provide a robust and repeatable process.
  • Key Features
  • 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.Wide Range of Part Processing Capabilities
  • Operates as tacker only, sealer only, or combined tacker-sealer.
  • Four-pass welding feature starts weld from centre and welds to the part corner– best for large parts sealing.
  • Set different energy levels for each axis welded for higher yields on rectangular parts.
  • Single or double side tack options.
  • Real time monitoring of weld inhibit inputs such as moisture, oxygen, and helium levels.
  • Unlimited weld schedule storage.
  • Lid hold-down feature assists tacking process.
  • Chain or link multiple schedules together.
