Patent Application
20170091918
This application claims priority to Chinese Patent Application No. 201510619320.X, filed on Sep. 25, 2015, the contents of which are incorporated by reference herein.
The subject matter herein relates to a printed circuit board checking system.
Printed circuit boards are necessary to electronic devices. The printed circuit board must be checked to determine whether it meets requirements. The printed board is checked by people.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
The image capture unit 20 and the light source 30 are attached to the movement mechanism 40 and positioned above the printed circuit board 90. The light source 30 lightens the printed circuit board 90. When the movement mechanism 40 moves, the image capture unit 20 relative to the printed circuit board 90 moves in X axis, Y axis and Z axis and continuously captures a number of images. The image capture unit 20 is charge couple device camera. The captured images includes elements of the printed circuit board 90 to be checked. In an embodiment, the captured images includes all elements of the printed circuit board 90. The image analyzing unit 50 analyzes the captured images to obtain an arrangement information of each element of the printed circuit board 90 to be checked. The storage unit 60 stores a standard arrangement information of each element of the printed circuit board 90 to be checked. The standard arrangement information includes a standard arrangement parameter and a standard arrangement image. The determining unit 70 determines whether the arrangement of elements of the printed circuit board 90 meets requirements and which element does not meet requirement according to the analyzed arrangement information of each element of the printed circuit board 90 to be checked and the standard arrangement information of each element of the printed circuit board 90 to be checked. The display unit 80 displays a checked result of the printed circuit board 90.
The movement mechanism 40 includes a left-right movement unit 42, a front-back movement unit 49, a vertical movement unit 44, a first drive unit 46, a second drive unit 48 and a third drive unit 41. Referring to
The movement mechanism 40 further includes a first switch 43, a second switch 45 and a third switch 47. The first switch 43 controls the left-right movement unit 42 to work in response to an operation to it. The second switch 45 controls the front-back movement unit 49 to work in response to an operation to it. The third switch 47 controls the vertical movement unit 41 to work in response to an operation to it.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
