Abstract
The present disclosure generally relates to devices, systems, and methods associated with optical data capture. In some embodiment, the present invention is a chassis for use in an imaging apparatus having an imaging sensor positioned fixedly relative to the chassis and a window. The chassis includes a cavity; a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity; and a lens assembly having a protrusion, the lens assembly being positioned within the cavity such that the protrusion is positioned within the slot, where the lens assembly is fixedly secured to the chassis only via a hardened adhesive.
Claims21
A method of installing a lens assembly having a protrusion within a chassis having a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity, the lens assembly having a corresponding imaging sensor positioned fixedly relative to the chassis, the method comprising:
- providing the chassis having a cavity configured to receive the lens assembly;
- positioning the lens assembly within the chassis such that the protrusion is positioned within the slot, the lens assembly being free-floating relative to the chassis;
- adjusting the lens assembly relative to the imaging sensor while the lens assembly is free-floating relative to the chassis;
- and
- upon meeting an adjustment threshold, fixedly securing the lens assembly to the chassis.
An imaging apparatus comprising:
- a housing having a window;
- a chassis positioned inside the housing, the chassis having a cavity and a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity;
- an imaging sensor positioned fixedly relative to the chassis;
- and
- a lens assembly having a protrusion, the lens assembly being positioned within the cavity such that the protrusion is positioned within the slot, the lens assembly being further positioned between the imaging sensor and the window,
- wherein the lens assembly is fixedly secured to the chassis only via a hardened adhesive.
A barcode reader comprising:
- a housing having a window;
- a chassis positioned inside the housing, the chassis having a cavity and a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity;
- an imaging sensor positioned fixedly relative to the chassis;
- and
- a lens assembly having a protrusion, the lens assembly being positioned within the cavity such that the protrusion is positioned within the slot, the lens assembly being further positioned between the imaging sensor and the window,
- wherein the lens assembly is fixedly secured to the chassis only via a hardened adhesive.
A chassis for use in an imaging apparatus having an imaging sensor positioned fixedly relative to the chassis and a window, comprising:
- a cavity;
- a slot extending through a cavity wall, the cavity wall defining at least a portion of the cavity;
- and
- a lens assembly having a protrusion, the lens assembly being positioned within the cavity such that the protrusion is positioned within the slot,
- wherein the lens assembly is fixedly secured to the chassis only via a hardened adhesive.
