This disclosure relates generally to a welded bracket structure for a multi-camera system.
The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. Some devices may include a multi-camera system that includes cameras held in place by a bracket formed of a single piece of material.
Some cameras may incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens. Furthermore, some cameras may incorporate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plane in front of the camera at an image plane to be captured by the image sensor. In some such AF mechanisms, the optical lens is moved as a single rigid body along the optical axis of the camera to refocus the camera.
This specification includes references to “one embodiment” or “an embodiment.” The appearances of the phrases “in one embodiment” or “in an embodiment” do not necessarily refer to the same embodiment. Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.
“Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units . . . ” Such a claim does not foreclose the apparatus from including additional components (e.g., a network interface unit, graphics circuitry, etc.).
“Configured To.” Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112, sixth paragraph, for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configure to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks.
“First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “first” and “second” values. The terms “first” and “second” do not necessarily imply that the first value must be written before the second value.
“Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B.
It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the intended scope. The first contact and the second contact are both contacts, but they are not the same contact.
The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.
Various embodiments described herein relate to a welded bracket structure for use in conjunction with multiple camera modules. In some examples, the welded bracket structure may provide a unitary body structure to which camera modules may be attached or otherwise coupled, e.g., to form a multi-camera system module that may be incorporated into a device, such as a phone or other computing device. The welded bracket structure may comprise at least two brackets that are welded together via one or more weld joints. Each of the brackets may be configured to couple with one or more camera modules. As a non-limiting example, a first bracket may be configured to couple with two camera modules, and a second bracket (that is welded to the first bracket) may be configured to couple with one camera module. The welded bracket structure may be T-shaped in various embodiments, which may enable a reduction in space consumption as compared to, e.g., a rectangular welded bracket structure. According to various embodiments, each of the first bracket and the second bracket may be formed by deep drawing a respective sheet of metal. In some embodiments, the welded bracket structure (and the techniques for forming the same) may not suffer from some manufacturing problems that may arise in other camera bracket structures, e.g., a T-shaped bracket structure formed via stamping a single sheet of metal (which may result in the metal being torn). Furthermore, the techniques described herein may reduce manufacturing costs, e.g., as compared to processes (e.g., CNC machining) used to form some other camera bracket structures.
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
As mentioned above, various embodiments include a welded bracket structure comprising at least two brackets that are welded together.
According to various embodiments, the first bracket 104 may be configured to couple with one or more camera modules (e.g., camera modules 110 and 112). Similarly, the second bracket 106 may be configured to couple with one or more other camera modules (e.g., camera module 114).
In some embodiments, the first bracket 104 may include a top wall 116 (also referred to herein as the “first top wall 116”) and one or more side walls 118 (e.g., side walls 118a-118d). The side wall(s) 118 may be oriented at a non-zero angle relative to the first top wall 116. As a non-limiting example, one or more of the side walls 118 may be orthogonal to the first top wall 116. In some examples, one or more of the side walls 118 may be oriented at a first angle relative to the first top wall 116, and another one or more of the side walls 118 may be oriented at a different, second angle relative to the first top wall 116.
The first top wall 116 may define one or more apertures, e.g., to receive at least a portion of a first set of one or more camera modules. As indicated in
In some embodiments, the second bracket 106 may include a top wall 128 (also referred to herein as the “second top wall 128”) and one or more side walls 130 (e.g., side walls 130a-130d). The side wall(s) 130 may be oriented at a non-zero angle relative to the second top wall 128. As a non-limiting example, one or more of the side walls 130 may be orthogonal to the second top wall 128. In some examples, one or more of the side walls 130 may be oriented at a first angle relative to the second top wall 128, and another one or more of the side walls 130 may be oriented at a different, second angle relative to the second top wall 128.
The second top wall 128 may define one or more apertures, e.g., to receive at least a portion of a second set of one or more camera modules. As indicated in
According to some embodiments, the first bracket 104 may be formed by deep drawing a first sheet of metal. Additionally, or alternatively, the second bracket 106 may be formed by deep drawing a second sheet of metal. However, the first bracket 104 and/or the second bracket 106 may be formed using any other suitable material and/or process. Example methods/processes for manufacturing a welded bracket structure for camera modules are described in further detail below with reference to
As mentioned above, the welded bracket structure 102 may include a weld joint arrangement 108 that couples the second bracket 106 with the first bracket 104.
In some embodiments, the weld joint arrangement 108 may include one or more weld joints to fixedly attach the first bracket 104 and the second bracket to one another, e.g., such that a first side wall 118a of the first bracket 104 abuts a second side wall 130a of the second bracket 106. According to various embodiments, the weld joint(s) may include one or more spot welds 136, e.g., as indicated in
In some non-limiting examples, the weld joint(s) may include a first set of one or more spot welds 136a (see detail view in
In some non-limiting examples, the weld joint(s) may include a seam weld 138 between a first interior edge of the first side wall 118a (of the first bracket 104) and a second interior edge of the second side wall 130a (of the second bracket 106). The first interior edge may at least partially define the first cutout portion of the first side wall 118a. The second interior edge may at least partially define the second cutout portion of the second side wall 130a. That is, the first interior edge and/or the second interior edge may define the combined cutout portion 144 in some embodiments.
In some non-limiting examples, the weld joint(s) may include side butt welds 140 and a top edge butt weld 142. A first side butt weld 140a may be produced between the first side wall 118a of the first bracket 104 and a first corner portion 146a the second bracket 106, e.g., as indicated in the detail view in
In various embodiments, the weld joint arrangement 108 (e.g., the spot weld(s) 136, the seam weld(s) 138, the side butt weld(s) 140, and/or the top edge butt weld(s) 142) may be configured to counteract forces (e.g., pull, torque, etc.) imposed on the welded bracket structure 102, such that the first bracket 104 and the second bracket 106 are maintained securely attached to one another. In some examples, the spot weld(s) 136 may be used to bring the first bracket 104 and the second bracket 106 together, e.g., such that the respective geometries of the first side wall 118a and the second side wall 130a abut one another. That is, the spot weld(s) 136 may be produced before the other types of weld joints in some non-limiting examples. In various examples, the first bracket 104 and the second bracket 106 may be welded to one another (e.g., via the weld joint arrangement 108) with the target of having no gaps between the first side wall 118a and the second side wall 130a. In some cases, gaps between the first side wall 118a and the second side wall 130a may negatively impact accuracy in the manufacturing and/or assembling of the welded bracket structure 102. Additionally, or alternatively, gaps between the first side wall 118a and the second side wall 130a may negatively impact accuracy of alignment between camera modules coupled to the welded bracket structure 102. As discussed below with reference to
At 306, the process 300 may include forming aperture(s) and/or cutout portion(s) on the first bracket. At 308, the process 300 may include forming aperture(s) and/or cutout portion(s) on the second bracket. In some non-limiting examples, the aperture(s) and/or cutout portion(s) may be formed by performing one or more piercing and/or punching operations on the first bracket and/or the second bracket.
At 310, the process 300 may include performing one or more lapping operations (e.g., rotational grinding) on a first top wall (e.g., the first top wall 116 in
At 312, the process 300 may include aligning the first bracket with the second bracket. For example, each of the first bracket and the second bracket may be positioned in respective attachment orientations so that they may be attached to one another, e.g., via welding. In some examples, a first cutout portion of the first bracket may be aligned with a second cutout portion of the second bracket. The first cutout portion may be defined by a first side wall (e.g., the first side wall 118a in
At 314, the process 300 may include welding the first bracket and the second bracket together. In various examples, the first bracket and the second bracket may be welded together via a weld joint arrangement (e.g., weld joint arrangement 108 described above with reference to
At 316, the process 300 may include performing one or more lapping operations on the first top wall of the first bracket and the second top wall of the second bracket, e.g., after the brackets have been welded together. The lapping operation(s) may be performed to ensure that the first top wall of the first bracket is flush with the second top wall of the second bracket. That is, in some embodiments the first top wall may be coplanar with the second top wall as a result of the lapping operation(s).
At 318, the process 300 may include plating the welded bracket structure. For example, the welded bracket structure may be plated with a material (e.g., nickel) to prevent corrosion, e.g., if the first bracket and/or the second bracket are formed of a material that is susceptible to corrosion (e.g., copper). In some examples, the plating may additionally, or alternatively, be performed on the first bracket and/or the second bracket individually, e.g., before the welding (at 314) as indicated by the dashed arrow in
As mentioned above, in various embodiments a welded bracket structure may include a cutout portion that may allow epoxy to flow from a first bracket to a second bracket, or vice-versa.
The welded bracket structure may include a first bracket 402 and a second bracket 404. While not shown in
In some examples, the multi-camera system may include a first camera module 406, a second camera module 408, and a third camera module 410. The first bracket 402 may at least partially encompass the first camera module 406 and the second camera module 408, e.g., such that they are adjacent to each other. The second bracket 404 may at least partially encompass the third camera module 410. In some embodiments, the multi-camera system of
According to various embodiments, the epoxy arrangement 400 may include a first epoxy 412 and/or a second epoxy 414. The first epoxy 412 and the second epoxy 414 may be different types of epoxies in some embodiments. In some non-limiting examples, the first epoxy 412 (e.g., a silver epoxy) may be used to electrically ground the welded bracket structure to the camera modules, and the second epoxy 414 may comprise a thermal epoxy.
In some examples, the first epoxy 412 may include one or more first portions 412a that provide an electrical connection between the welded bracket structure and the camera modules for the first bracket 402, e.g., to ground the welded bracket structure to those camera modules for electromagnetic interference (EMI) purposes. For example, the first portion(s) 412a may contact the first bracket 402 and a respective component (e.g., a shield can, a stiffener, etc.) of each of the first camera module 406 and the second camera module 408. Furthermore, the first epoxy 412 may include one or more second portions 412b that provide an electrical connection between the welded bracket structure and the camera modules for the second bracket 404, e.g., to ground the welded bracket structure to those camera modules for EMI purposes. For example, the second portion(s) 412b may contact the second bracket 404 and a component (e.g., a shield can, a stiffener, etc.) of the third camera module 410.
In some examples, the second epoxy 414 (e.g., a thermal epoxy) may be dispensed into the multi-camera system, e.g., in an epoxy potting process. A needle may be used to inject the second epoxy 414 into the multi-camera system via one or more injections points, such as the first injection point 414a and the second injection point 414b indicated in
In some embodiments, the first epoxy 412 and the second epoxy 414 may be dispensed into the multi-camera system after one or more of the camera modules are actively aligned. In performing such active alignment, the welded bracket structure may be used as a reference to align camera modules with one another. For example, the first camera module 406 (and/or the second camera module 408) may be placed in the welded bracket structure, and the third camera module 410 may be actively aligned to the first camera module 406 (and/or the second camera module 408). An ultraviolet (UV) flash epoxy (not shown) may be used during the active alignment process to mount the camera modules to the welded bracket structure. In some examples, the first epoxy 412 may be dispensed during a time period after the UV flash epoxy is dispensed and before the second epoxy 414 is dispensed. According to some examples, the second epoxy 414 may be dispensed (e.g., using the first injection point 414a and/or the second injection point 414b for potting) to produce a thermal fill that encompasses the camera modules. The second epoxy 414 may be dispensed until it reaches a particular height of the wall (e.g., the full height), which may increase rigidity and improve reliability of the multi-camera system.
According to some embodiments, each of the camera modules may include a flex circuit board. For example, the first camera module 406 may include a first flex circuit board 416, the second camera module 408 may include a second flex circuit board 418, and the third camera module 410 may include a third flex circuit board 420. The flex circuit boards may convey signals (e.g. power and/or control signals) from the respective camera modules to one or more other components outside of the welded bracket structure. In a non-limiting example, the multi-camera system may be included in a mobile device, and the flex circuit boards may convey signals from the respective camera modules to one or more components (e.g., processor(s), controller(s), etc.) of the mobile device that are external to the welded bracket structure.
At 504, the method 500 may include forming a second bracket of the welded bracket structure. For example, at 504a, forming the second bracket may include deep drawing a second sheet of metal. In some embodiments, forming the second bracket may include removing one or more portions of the second sheet of metal, at 504b. In various examples, one or more portions of the second sheet of metal may be removed to form one or more apertures, one or more cutout portions, and/or one or more reduced wall thicknesses, e.g., as described above with reference to
At 506, the method 500 may include welding the first bracket to the second bracket. In some examples, welding the first bracket to the second bracket may produce one or more weld joints that fixedly attach the first bracket to the second bracket, e.g., such that a first side wall of the first bracket abuts a second side wall of the second bracket. The first side wall may be adjacent a first top wall of the first bracket. The first top wall may define a first set of one or more apertures (e.g., apertures formed at 502b) to receive at least a portion of a first set of one or more camera modules. The second side wall may be adjacent a second top wall of the second bracket. The second top wall may define a second set of one or more apertures (e.g., an aperture formed at 504b) to receive at least a portion of a second set of one or more camera modules.
According to various examples, the welding the first bracket to the second bracket may include producing one or more spot welds, one or more seam welds, and/or one or more butt welds. The spot weld(s) may include a first spot weld and/or a second spot weld produced between the first side wall of the first bracket and the second side wall of the second bracket. The first spot weld may be located to a first side of a first cutout portion of the first bracket. The second spot weld may be located to a second side of the first cutout portion, the second side being opposite the first side. The seam weld(s) may include a seam weld produced between a first edge of the first side wall and a second edge of the second side wall. In some examples, the first edge may at least partially define the first cutout portion, and the second edge may at least partially define a second cutout portion of the second bracket. The butt weld(s) may include a first side butt weld, a second side butt weld, and/or a top edge butt weld. The first side butt weld may be produced between the first side wall of the first bracket and a first corner portion of the second bracket. The first corner portion may comprise a portion of the second side wall and a portion of a third side wall that is orthogonal to the second side wall and the second top wall. The second side butt weld may be produced between the first side wall of the first bracket and a second corner portion of the second bracket. The second corner portion may comprise another portion of the second side wall and a portion of a fourth side wall that is opposite the third side wall. The top edge butt weld may be produced between a first exterior edge of the first side wall and a second exterior edge of the second side wall.

Audio data may be retrieved from and/or transmitted to memory 602 and/or RF circuitry 608 by peripherals interface 618. In some embodiments, audio circuitry 610 also includes a headset jack (e.g., 712,
I/O subsystem 606 couples input/output peripherals on device 600, such as touch screen 612 and other input control devices 616, to peripherals interface 618. I/O subsystem 606 may include display controller 656 and one or more input controllers 660 for other input or control devices. The one or more input controllers 660 receive/send electrical signals from/to other input or control devices 616. The other input control devices 616 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 660 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 708,
Touch-sensitive display 612 provides an input interface and an output interface between the device and a user. Display controller 656 receives and/or sends electrical signals from/to touch screen 612. Touch screen 612 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.
Touch screen 612 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 612 and display controller 656 (along with any associated modules and/or sets of instructions in memory 602) detect contact (and any movement or breaking of the contact) on touch screen 612 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 612. In an example embodiment, a point of contact between touch screen 612 and the user corresponds to a finger of the user.
Touch screen 612 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 612 and display controller 656 may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 612. In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.
Touch screen 612 may have a video resolution in excess of 800 dpi. In some embodiments, the touch screen has a video resolution of approximately 860 dpi. The user may make contact with touch screen 612 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.
In some embodiments, in addition to the touch screen, device 600 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output.
