Abstract

The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by coupling a base of the cartridge to a carriage that is transported via a track. The track transports the carriages between various substations at which one or more parts are added to the base. The carriage may be lifted from the track by a lifter mechanism at each substation in order to perform assembly operations on the base. An inspection system may inspect the cartridges at various stages of completion at or between the various substations.

First claim

The invention claimed is:

1. An assembly substation comprising:
a robotic arm configured to assemble a partially-assembled cartridge with an outer body, the partially-assembled cartridge comprising a base, an atomizer, and a liquid transport element, the atomizer being coupled to the base, and the robotic arm comprising a gripper configured to grasp at least one of the partially-assembled cartridge or the outer body; and
a suction system configured to apply a negative pressure longitudinally through the outer body to facilitate assembly of the partially-assembled cartridge into the outer body.

2. The assembly substation of claim 1 , wherein the gripper is configured to grasp the outer body and direct the outer body over the partially-assembled cartridge, such that at least a portion of the atomizer and the liquid transport element are received within the outer body.

3. The assembly substation of claim 2 , wherein the gripper comprises a piston, the piston being in fluid communication with the suction system and configured to engage an end of the outer body to apply the negative pressure through the outer body.

4. The assembly substation of claim 3 , wherein the piston is configured to press the outer body into engagement with the base.

5. The assembly substation of claim 1 , wherein the gripper is configured to grasp the partially-assembled cartridge and direct the partially-assembled cartridge into the outer body, such that at least a portion of the atomizer and the liquid transport element are received within the outer body.

6. The assembly substation of claim 1 further comprising:
a bending mechanism configured to bend the liquid transport element; and
a substrate gripper configured to wrap a reservoir substrate at least partially around the bending mechanism, the bending mechanism being configured to retract relative to the partially-assembled cartridge following wrapping of the reservoir substrate such that the reservoir substrate is wrapped at least partially about and in contact with the liquid transport element.

7. The assembly substation of claim 6 , wherein the gripper is configured to receive the outer body therein while the bending mechanism receives the partially-assembled cartridge therein.

8. The assembly substation of claim 1 further comprising an inspection unit configured to determine if the partially-assembled cartridge is fit for further assembly.

9. The assembly substation of claim 8 , wherein the robotic arm is further configured to move the partially-assembled cartridge from a carriage to the inspection unit.

10. An assembly method comprising:
providing a partially-assembled cartridge comprising a base, an atomizer, and a liquid transport element, wherein the atomizer is coupled to the base;
providing an outer body configured to at least partially receive the partially-assembled cartridge;
grasping at least one of the partially-assembled cartridge or the outer body with a gripper of a robotic arm so as to assemble the partially-assembled cartridge with the outer body; and
applying a negative pressure to the outer body via a suction system to facilitate insertion of the partially-assembled cartridge into the outer body.

11. The assembly method of claim 10 , wherein the gripper is configured to grasp the outer body and direct the outer body over the partially-assembled cartridge, such that at least a portion of the atomizer and the liquid transport element are received within the outer body.

12. The assembly method of claim 11 , wherein applying the negative pressure to the outer body comprises engaging an end of the outer body with a piston of the gripper, the piston being in fluid communication with the suction system and configured to apply the negative pressure through the outer body.

13. The assembly method of claim 11 further comprising pressing the outer body into engagement with the base with the piston.

14. The assembly method of claim 10 , wherein the gripper is configured to grasp the partially-assembled cartridge and direct the partially-assembled cartridge into the outer body, such that at least a portion of the atomizer and the liquid transport element are received within the outer body.

15. The assembly method of claim 10 further comprising:
inserting the partially-assembled cartridge in a bending mechanism to bend the liquid transport element;
wrapping a reservoir substrate at least partially around the bending mechanism; and
retracting the bending mechanism relative to the partially-assembled cartridge following wrapping of the reservoir substrate, such that the reservoir substrate is wrapped at least partially about and in contact with the liquid transport element.

16. The assembly method of claim 10 further comprising moving the partially-assembled cartridge from a carriage to an inspection unit with the robotic arm prior to assembling with the outer body.

17. The assembly method of claim 16 , wherein the inspection unit is configured to determine if the partially-assembled cartridge is fit for further assembly.

18. The assembly method of claim 17 further comprising:
disposing of the partially-assembled cartridge if defective; and
providing a second partially-assembled cartridge comprising a base, an atomizer, and a liquid transport element, wherein the atomizer is coupled to the base.
