Adhesive application apparatus for use with an assembling machine
The invention relates to an adhesive application apparatus for use with an assembling machine for assembling operatively upper and lower components for carrying printhead integrated circuits. The application apparatus includes a plate and a dispensing mechanism which includes an adhesive reservoir, said mechanism being operatively engaged with said plate in a sealing and sliding manner, the mechanism configured to dispense adhesive onto the plate when sliding along the plate. The apparatus also includes a displacement mechanism to slide the dispensing mechanism along the plate, and a control system to control operation of the dispensing and displacement mechanisms.
1. An adhesive application apparatus for use with an assembling machine for assembling upper and lower components of a carrier for carrying printhead integrated circuits, the application apparatus comprising:
a plate for receiving thereon an adhesive;
a dispensing mechanism having an adhesive reservoir in contact with the plate, the adhesive reservoir being magnetically attracted to the plate to form a tight seal therewith and adapted to slide across the plate to dispense adhesive thereon;
a displacement mechanism to slide the adhesive reservoir along the plate; and
a control system to control operation of the dispensing and displacement mechanisms, wherein
the adhesive reservoir further includes a sealing member in contact with the plate, the sealing member for reducing a surface friction between the adhesive reservoir and the plate.
2. An adhesive application apparatus as claimed in claim 1 , wherein the dispensing mechanism is configured to dispense adhesive according to a pad printing technique.
3. An adhesive application apparatus as claimed in claim 1 , wherein the plate defines an etched channel shaped and dimensioned according to the upper component, so that a particular part of the upper component is covered in adhesive when the portion is placed on the plate.
4. An adhesive application apparatus as claimed in claim 1 , wherein the displacement mechanism includes a linear carriage and actuator engaged with the dispensing mechanism.
5. An adhesive application apparatus as claimed in claim 1 , wherein the adhesive reservoir is a glue cup.
