Technical Field

[0001] The utility model belongs to the field of detection systems, and particularly relates to an optical detection device for detecting the size of a data line plug. Background Art

[0002] Data cables are commonly used signal connection cables in daily life. The data cable plug mainly includes the shell, pin, etc. The size error directly affects the subsequent use experience and customer praise rate of the data cable. As customer requirements become more and more stringent, manufacturers have begun to introduce inspection processes. In order to improve the inspection speed of automatic assembly lines, visual image measurement solutions are usually used. However, since the data cable fixture will block some angles, the existing visual image measurement has many blind spots and cannot fully detect the size of the data cable plug. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.

[0017] Reference Figure 1 and Figure 2 The utility model discloses an optical detection device for detecting the size of a data line plug, comprising a workbench 11, on the upper side of which a guide rail 12, a camera bracket 13 and a main control machine are arranged. The camera bracket 13 is located on the side of the guide rail 12, and the guide rail 12 bulges upward when passing through the camera bracket 13. The guide rail 12 is provided with a plurality of data line clamps 32 that can move along the extension direction of the guide rail 12. The camera bracket 13 is provided with three cameras 20, and the three cameras 20 are electrically connected to the main control machine. The three cameras 20 take pictures toward the guide rail 12 along the three directions of XYZ respectively. When passing through the camera bracket 13, the plurality of data line clamps 32 rise to a position where they can be photographed by the three cameras 20, and then descend to avoid the camera bracket 13. The main control machine is provided with at least four windows, three of which correspond to the real-time images obtained by the three cameras 20, and the fourth window is provided with a table and displays a plurality of statistical data and the results of algorithm judgment.

[0018] The guide rail 12 rises first and then falls, which facilitates the transfer of the data cable clamp 32 to a position where it can be observed by three cameras at the same time. The three cameras simultaneously obtain the current size parameters of the data cable 31. Compared with reading parameters one by one, the movement error of the data cable clamp 32 is avoided, and the measurement accuracy is high. After the data cable clamp 32 falls, it cleverly avoids one of the cameras on the path, which is convenient to use. Figure 1As shown, if the guide rail 12 is kept horizontal, the data cable clamp 32 will hit the camera 20 on the right side. If the camera 20 there is placed at a high place, the camera 20 can only obtain pictures at an inclined angle. Since the surface of the data cable 31 plug is a smooth arc surface, the edge is not obvious in the photo, so the computer may make a wrong judgment when analyzing the image.

[0019] As an improvement of the above solution, the three cameras 20 are located on the side of the camera bracket 13 away from the data cable clamp 32. When the data cable 31 plug is kept horizontal, the three cameras 20 respectively obtain the front view, top view and side view of the data cable 31 plug. Figure 1 As shown, the camera 20 at the back is not shown due to being blocked by the camera bracket 13 .

[0020] As an improvement of the above solution, the raised portion of the guide rail 12 includes an upwardly inclined ascending section, a horizontally maintained section and a downwardly inclined descending section. Furthermore, the guide rail 12 is provided with a curved surface at a corner position to achieve a smooth transition.

[0021] As an improvement of the above solution, the cross section of the guide rail 12 is T-shaped, and the bottom of the data line clamp 32 is bent toward the guide rail 12 and clamps the two sides of the guide rail 12, ensuring that the data line clamp 32 can only move along the length direction of the guide rail 12. When the data line clamp 32 is placed in the guide rail 12, it can only be pushed in from the side.

[0022] As an improvement of the above scheme, the data cable clamp 32 includes a horizontal bottom plate and a first vertical plate and a second vertical plate respectively located on opposite sides of the bottom plate. A hole is provided in the middle of the first vertical plate for the data cable 31 to enter, and an elastic soft bag is provided inside the hole for temporarily clamping the four sides of the data cable 31 plug, but does not block the end of the data cable 31 plug; at this time, the end face of the data cable 31 plug can be seen from the back of the first vertical plate. A notch is provided on the upper side of the second vertical plate so that the tail of the data cable 31 can be placed into the notch from top to bottom. The bottom plate, the first vertical plate and the second vertical plate form a U shape, so that the data cable 31 plug is displayed suspended. The above scheme is adopted to facilitate the cameras 20 located at the top and the side to obtain the overall situation of the data cable 31 plug.

[0023] As an improvement of the above solution, two adjacent data cable clamps 32 are connected by a rope, and after the machine pulls the frontmost data cable clamp 32, the subsequent data cable clamps 32 are pulled and continue to move forward.

[0024] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different options and changes. The scope of the utility model is intended to be defined by the claims and their equivalents.
