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.

Claims

1. A system configured to assemble a plurality of cartridges for an aerosol delivery device, the system comprising:

a plurality of assembly substations collectively configured to assemble a base and a plurality of additional components together, the base extending between an inner end configured to receive the additional components during assembly of the cartridges and an attachment end defining an internal surface configured to engage a control body during usage of the aerosol delivery device;

a track extending between the assembly substations; and

a carriage configured to engage the track and to cooperate therewith to move between the assembly substations, the carriage comprising an engagement head defining a plurality of sections configured to engage the internal surface of the attachment end of the base via an interference fit to provide the assembly substations with access to the inner end of the base to attach the additional components thereto.

2. The system of claim 1, wherein the assembly substations include a base load substation, the base load substation being configured to rotationally align the base with the engagement head of the carriage and engage the base with the engagement head.

3. The system of claim 1, wherein the base load substation comprises an imaging device configured to detect a rotational orientation of the base based on image of the attachment end of the base.

4. The system of claim 1, wherein the carriage comprises a storage module configured to store cartridge identification and status information.

5. The system of claim 1, wherein the carriage defines one or more alignment apertures and the track comprises one or more locking pins configured to engage the alignment apertures to releasably lock the carriage at one or more of the assembly substations.

6. The system of claim 5, wherein the track further comprises a conveyor and a lifter mechanism, the lifter mechanism comprising the locking pins and being configured to lift the carriage from the conveyor.

7. The system of claim 1, wherein the carriage comprises an electrostatic dissipative material.

8. The system of claim 7, wherein the carriage further comprises a locator module comprising a ferromagnetic material.

9. An assembly method, comprising:

providing a base and a plurality of additional components collectively configured to form a plurality of cartridges for an aerosol delivery device, the base extending between an inner end configured to receive the additional components during assembly of the cartridges and an attachment end defining an internal surface configured to engage a control body during usage of the aerosol delivery device;

providing a plurality of assembly substations, a track, and a carriage comprising an engagement head defining a plurality of sections, the track extending between the assembly substations, and the carriage being configured to engage the track and to cooperate therewith to move between the assembly substations;

engaging the internal surface of the attachment end of the base with the sections of the engagement head via an interference fit to provide the assembly substations with access to the inner end of the base;

transporting the carriage by way of the track between the assembly substations; and

assembling the additional components with the inner end of the base at the assembly substations.

10. The assembly method of claim 9, wherein engaging the base with the engagement head comprises rotationally aligning the base with the engagement head.

11. The assembly method of claim 10, wherein rotationally aligning the base with the engagement head comprises detecting a rotational orientation of the base based on image of the attachment end of the base.

12. The assembly method of claim 9, further comprising storing cartridge identification and status information in a storage module coupled to the carriage.

13. The assembly method of claim 9, further comprising locking the carriage at one or more of the substations by directing one or more locking pins from the track into one or more alignment apertures defined in the carriage.

14. The assembly method of claim 13, wherein transporting the carriage by way of the track comprises transporting the carriage by way of a conveyor, and wherein locking the carriage comprises lifting the carriage from the conveyor.
