Optical components (e.g., lenses, prisms, photosensors, or the like) may be susceptible to damage (e.g., scratches) or contamination (e.g., dust) from a wide variety of sources. The optical components may be stored and/or transported in gel packs. Gel packs may be expensive, require modification of manufacturing processes, and have a low part density (e.g., the number of optical components per unit area).
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
The present inventors have recognized, among other things, that a problem to be solved may include storing and transporting optical components such that the optical components are less susceptible to damage. The present inventors have recognized, among other things, that a problem to be solved may include storing and transporting optical components such that the optical components are less susceptible to contamination. The present inventors have recognized, among other things, that a problem to be solved may include storing and transporting optical components such that the optical components are less susceptible to moving out of the position in which they were stored. The present inventors have recognized, among other things, that a problem to be solved may include storing and transporting optical components such that the optical components are less susceptible to electrostatic discharge.
The present subject matter may help provide a solution to these problems, such as by providing an optical component storage tray. The optical component storage tray may be used for transporting the optical components. The optical component storage tray may define a plane. The tray may include a top side. The top side may be a first side. The tray may include a bottom side. The bottom side may be a second side. The top side and bottom side may be located on opposite sides of the plane. The tray may include a plurality of sockets. The plurality of sockets may be positioned on the top side. The plurality of sockets may include engaging features. The plurality of sockets may include a pocket. The pocket may be configured to receive an optical component. The tray may include a plurality of plugs. The plurality of plugs may be positioned on the bottom side. The plurality of plugs may include mating features. The mating features and the engaging features may be configured to intermesh. The tray may be formed from a composite material. The composite material may include a polycarbonate matrix. The composite material may include a dispersed carbon phase.
The present subject matter may help provide a solution to these problems, such as by securely retaining the optical component within the pocket. Securely retaining the optical component may include entirely or substantially inhibiting the movement of the optical component in relation to the tray. Securely retaining the optical component may prevent undesirable movement of the optical component. Movement of the optical component may damage the optical component. Movement of the optical component may result in the optical component not being in the position in which the optical component was stored. The present subject matter may help provide a solution to these problems, such as by forming the tray from the composite material. The composite material may prevent a build-up of electrostatic charge. Preventing the build-up of electrostatic charge may prevent the attraction of foreign material to the optical components stored within the tray. Preventing the build-up of electrostatic charge may prevent an electrostatic discharge to the optical component. The present subject matter may help provide a solution to these problems, such as by allowing a greater number of optical components to be stored in a specific area (e.g., increased part density). The part density may increase due to providing sufficient retention and protection of the optical components, in an area less than what is required for gel packs.

The optical component may extend into the void 145 and still be protected and/or sealed from the external environment (or foreign material contained therein).
The assembly 450 may include the first tray 400A and the second tray 400B. The first tray 400A and the second tray 400B may include the plurality of sockets 130. Each of the plurality of sockets 130 may include the pocket 132. The first optical component 570A may be positioned within an individual socket of the plurality of sockets 130. The first optical component 570A may be positioned within the pocket 132. Each of the plurality of sockets 130 may include the first optical component 570A or a second optical component 570B.
The assembly 450 may include a target surface 580. The target surface 580 may include a first target position 582A. The target surface 580 may include a second target position 582B. The pick and place machine 560 may be configured to transport the first optical component 570A and/or the second optical component 570B.

The pick and place machine 560 may be configured to transport each of the optical components contained within the plurality of sockets 130 to a corresponding number of target positions. The assembly 450 may include additional target surfaces having additional target positions. The pick and place machine 560 may be configured to transport the first optical component 570A and/or the second optical component 570B from their respective pockets (e.g., pocket 132) to the additional target positions.
The method 600 may also include that removing the second optical component storage tray demeshes engaging features (e.g., the engaging features 134 and 136 of
The method 600 may also include that picking the optical component from the first position includes grasping the optical component with mechanical pincers. The method 600 may also include that picking the optical component from the first position includes applying a vacuum to the optical component. The method 600 may also include that picking the optical component from the first position includes coupling a magnet to the optical component. The method 600 may also include that placing the optical component at the second position includes generating a magnetic field, thereby decoupling the magnet from the optical component. In an example, the attractive forces between the optical component and the magnet may be cancelled out by a magnetic field located near the magnet and the optical component, thereby causing the optical component to decouple from the magnet.

The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are also referred to herein as “examples.” Such examples may include elements in addition to those shown or described. However, the present inventors also contemplate examples in which only those elements shown or described are provided. Moreover, the present inventors also contemplate examples using any combination or permutation of those elements shown or described (or one or more aspects thereof), either with respect to a particular example (or one or more aspects thereof), or with respect to other examples (or one or more aspects thereof) shown or described herein.
In the event of inconsistent usages between this document and any documents so incorporated by reference, the usage in this document controls.
In this document, the terms “a” or “an” are used, as is common in patent documents, to include one or more than one, independent of any other instances or usages of “at least one” or “one or more.” In this document, the term “or” is used to refer to a nonexclusive or, such that “A or B” includes “A but not B,” “B but not A,” and “A and B,” unless otherwise indicated. In this document, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.” Also, in the following claims, the terms “including” and “comprising” are open-ended, that is, a system, device, article, composition, formulation, or process that includes elements in addition to those listed after such a term in a claim are still deemed to fall within the scope of that claim. Moreover, in the following claims, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects.
Geometric terms, such as “parallel”, “perpendicular”, “round”, or “square”, are not intended to require absolute mathematical precision, unless the context indicates otherwise. Instead, such geometric terms allow for variations due to manufacturing or equivalent functions. For example, if an element is described as “round” or “generally round,” a component that is not precisely circular (e.g., one that is slightly oblong or is a many-sided polygon) is still encompassed by this description.
Method examples described herein may be machine or computer-implemented at least in part. Some examples may include a computer-readable medium or machine-readable medium encoded with instructions operable to configure an electronic device to perform methods as described in the above examples. An implementation of such methods may include code, such as microcode, assembly language code, a higher-level language code, or the like.
