FIELD OF THE EMBODIMENTS

The field of the embodiments is video inspection gear. More specifically, the embodiments are directed to the use of video inspection of a printed wire board and other electronic devices at a remote location for inspection purposes.

BACKGROUND OF THE EMBODIMENTS

There are numerous instances in industrial practice that inspection of components is required. This is also true in the electronic component industry. Visual inspection has long been a required step in any quality control procedure. In many cases the manufacturer must have visual inspection performed by the customer of the project. This is particularly true in the aerospace industry where visual inspection of the components is a requirement of the final customer. In the past, this inspection required the customer to travel to the location of the manufacturer to inspect the product and the process. This is a costly process, requiring travel expenditure for a few people to perform the visual inspection. The overall purpose of the embodiments described herein is to provide a remote video inspection system that will save significant costs and improve the quality of visual inspections.

SUMMARY OF THE EMBODIMENTS

The embodiments of the Remote Video Inspection System are comprised of a remote video inspection hardware assembly and a remote video inspection software system. The hardware assembly is comprised of a video camera, an adjustable video camera mount, magnification control of the camera, and a means to view the component from varying positions and angles. The video inspection software system is comprised of both a local and remote component. The local component is operated by a technician who oversees the remote inspection, and allows for setup, manual positioning, and manual camera adjustment. The remote component is operated by an inspector, and provides video feed to them, as well as a system to control the viewing angle and position of the component and camera. In addition, the remote component can be viewed by multiple clients, though only the inspector has control of viewing angle and position.
There has thus been outlined, rather broadly, the more important features of the embodiments of the Remote Video Inspection System in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the embodiments that will be described hereinafter and which will form the subject matter of the claims appended hereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the Remote Video Inspection System comprise a remote video inspection hardware assembly 110 and a video inspection software system 400.
The remote video inspection hardware assembly 110 is comprised of a camera 101 and a stage assembly 110.
The stage assembly 110 is comprised of a horizontal gimbal 102, an outer gimbal 103, and an inner gimbal 104, a base plate 108, and a component table 301.
The camera 101 is a video camera with zoom, pan, and tilt capability. The camera is located adjacent to stage assembly 110 and is used to view any object mounted on the stage assembly 110.
The horizontal gimbal 102, outer gimbal 103, and inner gimbal 104 are combined to provide three axes of rotation so that a component to be viewed and mounted on the component table 301 can be oriented in any direction. The angular ranged of the horizontal gimbal 102 is 360 degrees (360°). The angular range of the outer gimbal 103, and inner gimbal 104 is 90 degrees (90°).
The horizontal gimbal 102 is comprised of a gear ring 109 and a horizontal gimbal motor 105. The horizontal gimbal motor 105 provides power to the gear ring 109 based on signals received from the video inspection software system to place the component to be viewed in the proper orientation.
The outer gimbal 103 is comprised of an outer gimbal motor 106. The outer gimbal 103 is mechanically connected to the outer gimbal motor via an outer gimbal cam 202. The outer gimbal motor 106 provides power to the outer gimbal 103 based on signals received from the video inspection software system to place the component to be viewed in the proper orientation.
In an analogous manner, the inner gimbal 104 is comprised of an inner gimbal motor 107. The inner gimbal 104 is mechanically connected to the inner gimbal motor 107 via an inner gimbal cam 203. The inner gimbal motor 107 provides power to the inner gimbal 104 based on signals received from the video inspection software system to place the component to be viewed in the proper orientation. The inner gimbal 104 forms an inner gimbal cam aperture.
Alternatively, a component table 301 is affixed to the base plate 108 via fasteners. The base plate 108 is in turn affixed to the horizontal gimbal 102 via fasteners. The stage assembly 110 can be affixed to a support of any kind in any orientation via the component table 301.
The video inspection software system 400 is comprised of local and remote components. The remote component of the video inspection software system 400 is comprised of one or more remote client with inspection controls 401, one or more remote viewing interfaces 402, and a log-in system 403. The local component of the video inspection software system 400 is comprised of a local controller 405 at the location of the component to be viewed wherein the controller 405 is in turn connected via a video connection to the camera 101 and to the horizontal gimbal motor 105, the outer gimbal motor 106, and the inner gimbal motor 107. The remote client with inspection controls 402 allows a remote user to view the video signal from the camera 101 and control the position of the component stage assembly 110 through interactive controls on the user interface. The one or more remote viewing interfaces 402 allows a remote user to view the video without controlling the local hardware system.
One use of Remote Video Inspection System is to inspect a printed wiring board (PWB). However, it should be emphasized that the Remote Video Inspection System can be used to remotely view any device or project that should be inspected. In the inspection of PWBs the system will accommodate a PWB with dimensions up to that of 17 inches wide by 19 inches long and with components 3 inches deep, a video camera that can capture images from various angles, wherein the video camera is capable of adjustments to orientation and field of view; and wherein the hardware assembly provides a platform on which to view the inspection component from varying positions and angles.
The Remote Video Inspection System can be used to observe the fit of a PWB into a chassis while the board is being installed. As another example, the Remote Video Inspection System can be used to observe the installation of components and the torque and force loading on components during installation. In another example, the Remote Video Inspection System can be used to inspect the conformance of solder joints relative to defined standards such as JSTD 001 and NASA Standard 8739 et seq.
The video inspection software system 401 is further comprised of a local and remote camera control means, means to pre-program camera movements so the same views can be captured on multiple boards, a local and remote camera magnification control means, a recording means for video, a means to automatically reference components on the video with a corresponding Computer Aided Design (CAD) electrical design and schematics; PWB safety means so that the Remote Video Inspection hardware assembly is incapable of touching the PWB, and wherein the Remote Video Inspection software can be interfaced with a remote system over the internet.
