A company manufacturing orthodontic components required a special system to prepare "assembly cards" to be used with their products. The card required discreet, variable amounts of a special UV curable adhesive to be applied at multiple sites on each card. Following the adhesive dispense, a foil cover sheet needed to be formed and hermetically seal over the dispensed adhesive. Additionally, a component was to be attached to the card, coded with an I.D. number and the finished assembly needed to be collated into stacks of 5 for packaging.
Drawing on Creative Automations extensive dispensing experience, a special heated servo driven linear dispense pump was designed and incorporated into the system. Card blanks are placed in a hopper and are automatically processed through the 8 stations using a walking beam style conveyor. The next station started with a roll of foil which was formed and die cut prior to placement and heat seal onto the card. The next stations performed the attachment of another component, ink jet printing and additional processing. The completed card was transferred onto an accumulation conveyor which assembled the cards into stacks of 5.
