The function is as follows: (1) The middle part of the top surface of the bottom plate is provided with a reference plate, the left side edge or the right side edge of the top surface of the reference plate is provided with an X-direction positioning baffle plate extending forwards and backwards, the front side edge or the rear side edge of the top surface of the reference plate is provided with a Y-direction positioning baffle plate extending leftwards and rightwards, and the X-direction positioning baffle plate and the Y-direction positioning baffle plate can position a test fixture placed on the top surface of the reference plate; therefore, the test fixture can lean against the inner side surfaces of the X-direction positioning baffle plate and the Y-direction positioning baffle plate respectively through the two sides of the included angle, so that the test fixture can be rapidly positioned and in place.

For further convenience, those skilled in the art will understand the technical solutions of the present utility model, the following will illustrate:

1. the system operation description of the utility model:

(1) The clamp is taken manually, the two-dimensional code on the tool code of the test clamp is scanned manually by the code scanning gun 13, and after scanning is completed, the clamp is placed in a workbench (namely a reference plate) and pushed to be positioned by the side.

2. For example, referring to fig. 3, the workflow is: the method comprises the steps of starting equipment, opening a shutter (namely a window shade on a shell), scanning codes (scanning the test jig by using a code scanner, and inputting a next step after the codes are input without scanning the codes), starting a button (a starting button on the shell, which is in a waiting state when not pressed), moving the jig to a camera scanning starting point position 1, sending a visual photographing command 1, waiting for a visual software reply 1, judging the visual software reply result 1, moving to a camera scanning starting point position 2, sending the visual photographing command 2, waiting for the visual software reply 2, judging the visual software reply result 2, moving to a camera scanning starting point position 3, sending the visual photographing command 3, waiting for the visual software reply 3, judging the visual software reply result 3, moving to a camera scanning starting point position 4, sending the visual photographing command 4, waiting for the visual software reply 4, waiting for the visual software end flow, acquiring and analyzing the result, performing data flow processing and maintaining data.

3. Defect solutions, practical examples:

A. in order to prevent inaccurate positioning of components on the PCBA board and inconsistent heights of the components, the height and the flatness of the pressing bars of the clamp are required to be controlled, and the pressing bars are required to be detected one by one. The number of the pressing bars on the single clamp is about 350 in this case, the diameter of the size cross section is about 3 mm-20 mm, and the heights are consistent. The number of the pressing bars is extremely large, the height of the pressing bars is required to be controlled to be 20mm plus or minus 0.1mm, and the flatness of the whole pressing bars is required to be 0.2mm.

When the height of the pressing rod is too high, for example, 20.12mm, components can be pressed, so that the components are offset and cannot be installed in place;

when the height of the pressing rod is too low, such as 19.85mm, the fixed components cannot be pressed;

when the flatness of the whole press bars exceeds 0.2mm, the whole components on the PCBA board can be offset, and the cold joint is easy to occur.

In order to improve the yield of PCBA board paster, consequently detect anchor clamps pressure stick height and planarization through using 3D structure light camera vision fixed point to shoot.

B. At present, the existing detection mode of the height and flatness of the pressing rod adopts manual meter-beating measurement and three-coordinate detection, has low detection efficiency and is easy to misdetect.

If the fixture needs to be rapidly and effectively positioned and fixed through development equipment, whether the measured fixture is in place or not can be monitored, the fixture is placed flatly, the rapid taking and the rapid transformation time are convenient to achieve and less than 5 minutes, and simultaneously, the fixture is compatible with 800mm in length, 600mm in length, 180mm in height and maximum dimension of the measured fixture, 400mm in minimum dimension and 80mm in length, 400mm in minimum dimension.

In order to solve the problems, a reference plate is designed in the equipment, the flatness of the placing clamp is guaranteed to be 0.15mm, and the clamp is positioned by two sides respectively by using 2 in-place sensors and positioning baffles of an XY axis, so that the clamp is positioned quickly and in place.

And the camera positions are adjusted by adopting the mode of carrying 3D structure light cameras on the X-axis, Y-axis and Z-axis linear modules respectively so as to be compatible with clamps with different lengths, widths and heights.

Wherein, when different clamps are compatible, the XYZ axes can be driven. In the test process, the camera can also move through the XZY shaft to realize multi-point photographing.

C. In order to facilitate rapid identification and screening of the press bars, after the 3D structure light camera is adopted for scanning, a background automatically marks the press bars and displays the press bars on a display screen in a picture mode.

Description: and (3) taking one calibrated pressing rod as a reference, and comparing other pressing rods with the reference pressing rod in data.

When the dimensions deviate negatively, the cumulative average of signed values across all press bars is given an absolute sign. Thereby judging the flatness and the height.

4. Summarizing: the novel 3D structure light camera vision detection fixture has the functions of detecting the height, flatness and the like of the pressing rod, the 3D structure light camera is used for performing multipoint positioning photographing, the height and flatness of the pressing rod in the fixture are detected, and meanwhile, the distance is adjusted through movement of the camera, so that the novel 3D structure light camera vision detection fixture can be compatible with multiple fixtures with different heights. The operation of each motion mechanism is controlled through the PC of the upper computer, and each pressing rod is quickly and automatically selected for calibration through one-key importing of the processed fixture 2D drawing. And in the photographing process, photographing detection analysis is carried out on the pressing bars in the whole area respectively, so that the detection efficiency is improved, the height and the flatness of each pressing bar of the clamp are ensured, the false detection of the pressing bars of the manual detection clamp is reduced, and the reject ratio of the patch PCBA is greatly reduced.

Description: the original 2D drawing is not compared with the picture shot by the 3D camera, the press bar is firstly selected by the clamp 2D drawing, and the press bar calibration tool can be quickly and automatically selected when the clamp 2D drawing is subsequently used for calibrating a visual template, so that the clamp 2D drawing belongs to the pre-processing work.

Judging whether the pressing rod is qualified or not, wherein the pressing rod is automatically set within a certain parameter tolerance range, and the internal program analysis data of the picture software shot by the 3D camera belongs to a conventional software algorithm.

The 2D drawing is only theoretical data and is used for pre-processing, and belongs to calibration, but the 3D camera shoots, and the shooting is of a physical clamp, and the clamp has machining errors. It is therefore desirable to know what the errors exist between the theoretical data of the design jig and the physical jig, which is what we want.
