Remanufactured inkjet printer cartridge, system and process
View Patent ↗Systems, methods and structures for remanufacturing inkjet printer cartridges and inkjet printer print heads by removing the print head and adhesive holding the print head to a used inkjet printer cartridge, preparing the cartridge housing for a new print head by routing out the used print head and used adhesive to create a new mounting surface for new adhesive and a new print head, placing the adhesive and new print head on the new mounting surface, curing the adhesive and assembling a re-manufactured cartridge from the cartridge housing having a new print head positioned thereon.
1. A process comprising:
providing an inkjet printer cartridge wherein at least a portion of ink has been depleted; and
replacing a print head assembly integrated with the inkjet printer cartridge with another print head assembly.
2. The process of claim 1 , wherein the inkjet printer cartridge comprises:
a housing defining an opening;
a foam disposed at least partially within the housing;
a cap covering the opening of the housing; and
filter disposed within the housing.
3. The process of claim 2 , wherein the print head assembly is coupled with the housing.
4. The process of claim 2 , further comprising:
removing the cap;
removing the foam; and
removing the ink from the housing.
5. The process of claim 4 , further comprising washing the foam.
6. The process of claim 5 , further comprising removing the filter prior to removing ink from the housing.
7. The process of claim 2 , further comprising electrically testing the inkjet printer cartridge.
8. The process of claim 7 , further comprising inserting another foam or a washed foam into the inkjet printer cartridge after electrically testing the inkjet printer cartridge.
9. The process of claim 8 , further comprising installing a the cap on the housing.
10. The process of claim 9 wherein installing the cap is by ultrasonic welding.
11. The process of claim 1 , wherein the print head assembly comprises:
a print head;
electrical contacts; and
a flexible board electrically associated with the print head and the electrical contact.
12. The process of claim 11 , wherein the print head is coupled with the housing.
13. The process of claim 12 , wherein the flexible board is coupled with the housing.
14. The process of claim 13 , wherein replacing a print head assembly associated with the inkjet printer cartridge with another print head assembly comprises:
heating the inkjet printer cartridge to decouple the flexible board and the housing;
applying routing bit to decouple the print head and the housing; and
coupling the another print head assembly to the housing.
15. The process of claim 14 , further comprising:
washing the housing after the print head is decoupled from the housing; and
drying the housing.
16. The process of claim 14 , wherein coupling the another print head assembly to the housing comprises:
applying adhesive to the housing;
pressing the another print head assembly onto the adhesive.
17. The process of claim 16 , further comprising curing the adhesive after pressing the another print head assembly onto the adhesive.
18. The process of claim 16 , further comprising bending the another print head assembly over an edge of the housing.
19. The process of claim 18 , further comprising applying heat and pressure to the another print head assembly to activate said adhesive.
20. The process of claim 16 , wherein applying adhesive comprises applying a two-component, epoxy amine or acrylic based adhesive.
21. The process of claim 16 , wherein applying adhesive comprises dispensing said adhesive with a robotic dispensing machine.
22. The process of claim 1 , wherein the another print head assembly comprises:
a print head;
electrical contacts; and
a flexible board electrically associated with the print head and the electrical contact.
23. A system comprising:
a fixture configured to hold a housing of an inkjet printer cartridge in a first position;
a swivel locking bar associated with the fixture and configured to releasably lock the housing in the fixture;
a computer-controlled router configured to remove a first print head assembly coupled with the housing; and
a robotic arm configured to couple a second print head assembly to the housing.
24. A method comprising:
providing an inkjet printer cartridge; and
removing a print head assembly integrated with the inkjet printer cartridge, wherein the print head assembly comprises a print head, electrical contacts, and a flexible board electrically associated with the print head and the electrical contact, wherein removing a print head assembly associated with the inkjet printer cartridge comprises heating the inkjet printer cartridge to decouple the flexible board and the inkjet printer cartridge and applying a routing bit to decouple the print head and the inkjet printer cartridge.
25. A method comprising:
providing an inkjet printer cartridge wherein a first print head assembly has been removed; and
coupling a second print head assembly directly with the inkjet printer cartridge, wherein coupling a second print head assembly to the inkjet printer cartridge comprises applying an adhesive to the inkjet printer cartridge and pressing the second print head assembly onto the adhesive.
26. The method of claim 25 , further comprising curing the adhesive after pressing the second print head assembly onto the adhesive.
27. The method of claim 25 , further comprising bending the second print head assembly over an edge of the inkjet printer cartridge.
28. The method of claim 27 , further comprising applying heat and pressure to the second print head assembly to activate said adhesive.
29. The method of claim 25 , further comprising electrically testing the inkjet printer cartridge.
