Description

Technical Field

[0001] This utility model relates to the field of automated assembly equipment technology, and in particular to a connector AOI detection module. Background Technology

[0002] AOI (Automated Optical Inspection) is an intelligent inspection system based on optical principles and machine vision technology. It is primarily used for quality inspection in industrial production, particularly in the electronics manufacturing field (such as PCB boards and semiconductors). When assembling serial boards and connectors, AOI is typically used to inspect the male and female connectors of both the serial board and the connector before they are fully engaged. In existing technology, a camera perpendicular to the plane being tested is used to capture images, which are then transmitted back to the system to determine if there are any abnormalities in the male and female connectors. However, this method only obtains a projected view; if there are abnormalities in the connector pins or other components, they cannot be detected in time. Furthermore, after the serial board is engaged with the upper housing, the male and female connectors are inside the upper housing and cannot be directly observed with the naked eye. If abnormalities are not detected in time, troubleshooting after assembly requires disassembling the entire assembly, which is time-consuming and labor-intensive.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a connector AOI detection module.

[0005] The technical solution of this utility model is as follows: This utility model provides a connector AOI detection module, including: a mounting plate and three sets of cameras disposed on the mounting plate, one set of cameras being disposed in a direction perpendicular to the plane being measured, and the other two sets of cameras being disposed on both sides. The cameras on both sides are tilted, and the center lines of the cameras on both sides and the focal point of the camera disposed in the middle converge on the plane being measured. The cameras are electrically connected to the control system.

[0006] Furthermore, the cameras on both sides are symmetrically arranged with respect to the central camera.

[0007] Furthermore, the front end of each of the three sets of cameras is provided with a ring light source, and the framing areas of the three sets of cameras respectively pass through the central through hole of the ring light source.

[0008] Furthermore, the mounting plate is provided with several adjustment slots corresponding to the cameras on both sides, and the cameras on both sides are respectively fixed on the adjustment slots.

[0009] Furthermore, the present invention also includes: a linear motor and a movable bracket disposed on the moving end of the linear motor, wherein the mounting plate is disposed on the movable bracket.

[0010] Furthermore, a position guidance camera is installed on the mobile support.

[0011] By adopting the above solution, this utility model uses three sets of cameras to acquire images from different angles, thereby ensuring visual inspection of the pins and other components on both sides of the male and female connectors. This allows for timely determination of any abnormalities in the connectors, avoiding the need to disassemble the serial board and the upper shell for inspection only after assembly, thus ensuring product yield.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please see Figure 1 This utility model provides a connector AOI detection module, including: a mounting plate 1 and three sets of cameras 2 disposed on the mounting plate 1. One set of cameras 2 is disposed in a direction perpendicular to the plane being measured, and the other two sets of cameras 2 are disposed on both sides. The cameras 2 on both sides are tilted and the center lines of the cameras 2 on both sides and the focal point of the camera 2 disposed in the middle converge on the plane being measured. The cameras 2 are electrically connected to the control system.

[0017] When it is necessary to perform corresponding AOI inspection on the connectors on the serial board or connector, the serial board or connector is moved to the inspection area of ​​the corresponding AOI inspection module. Three sets of cameras 2 acquire images from different angles to ensure visual inspection of the pins and other parts on both sides of the male and female connectors. This allows for timely judgment of whether there are any abnormalities in the corresponding connectors, avoiding the situation where defects are detected only after assembly and the serial board and the upper shell need to be disassembled for inspection, thus ensuring product yield.

[0018] In some embodiments, please refer to Figure 2The mounting plate 1 is placed on the machine base, and the camera 2 is oriented upwards. This allows the three sets of cameras 2 positioned below to detect and identify the connectors at the bottom of the serial board before assembly. In some embodiments, please refer to... Figure 1 The mounting plate 1 is suspended above the machine platform, and the camera 2 is oriented downwards. This allows the three sets of cameras 2 located above to perform corresponding detection and identification of the connectors on the upper shell before the upper shell is assembled.

[0019] In some embodiments, the cameras 2 on both sides are symmetrically arranged about the middle camera 2, so as to effectively recognize the pins on both sides of the connector and the internal pins, and ensure the stability of the detection effect.

[0020] In some embodiments, a ring light source 3 is provided at the front end of the three sets of cameras 2, and the viewing areas of the three sets of cameras 2 respectively pass through the central through-hole of the ring light source 3. Supplemental lighting through the ring light source 3 can eliminate the influence of shadows generated under lighting conditions on image recognition, and improve the accuracy of determining connector malfunctions.

[0021] In some embodiments, the mounting plate 1 has a plurality of adjustment slots corresponding to the cameras 2 on both sides, and the cameras 2 on both sides are respectively fixed to the adjustment slots. In some optional embodiments, the adjustment slots are arc-shaped holes to facilitate the rotation of the cameras 2 on both sides along the adjustment slots and to ensure that their focus remains on the measured surface, thereby reducing the response work of focusing after adjustment.

[0022] In some embodiments, please refer to Figure 3 This utility model also includes: a linear motor 4, and a movable bracket 41 disposed on the moving end of the linear motor 4, with the mounting plate 1 disposed on the movable bracket 41. The linear motor 4 drives the movable bracket 41 to translate, thereby meeting the movement requirements of the AOI inspection module and the inspection requirements of the upper shell. Multiple sets of products can be inspected separately, improving inspection efficiency, or providing clearance for product movement to avoid interference, thus adapting to different working conditions.

[0023] In some embodiments, a position guidance camera 52 is provided on the movable support 41. The guidance camera 52 acquires and recognizes images of the product's feeding direction to determine the product's position, and then the linear motor 4 moves the AOI detection module to the corresponding position to perform AOI detection and recognition of the product.

[0024] In summary, this utility model uses three sets of cameras 2 to acquire images from different angles, thereby ensuring visual inspection of the pins and other components on both sides of the male and female connectors. This allows for timely determination of any abnormalities in the connectors, avoiding the need to disassemble the serial board and the upper shell for inspection only after assembly, thus ensuring product yield.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
