Description

Technical Field

[0001] This utility model relates to the field of metal terminal testing technology, specifically to a metal terminal size testing mechanism for vehicle connectors. Background Technology

[0002] In the automotive connector manufacturing industry, metal terminals, as core components for current transmission, directly affect the electrical performance and mechanical reliability of connectors due to their dimensional accuracy. Currently, the industry primarily relies on two methods for dimensional inspection of metal terminals: one is contact measurement, which involves manual or semi-automatic point-by-point measurement of key terminal components using mechanical measuring tools (such as calipers and micrometers); the other is non-contact optical inspection, which uses a fixed industrial camera to capture two-dimensional images of the terminals from a preset angle, and then analyzes the dimensional data using image processing software. Some automated production lines incorporate conveyor systems to transport terminals to the inspection station, where robotic arms perform positioning and image acquisition. These methods are widely used in basic dimensional inspection scenarios, especially in the sampling inspection of simple parameters such as length and width.

[0003] However, existing technologies still have significant limitations. First, fixed-view optical inspection cannot cover the three-dimensional structural features of metal terminals, such as the tilt angle of the terminal sidewall, the depth of the bottom groove, or the curvature of the pin, resulting in blind spots. To address this, we propose a metal terminal size inspection mechanism for automotive connectors. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a metal terminal size detection mechanism for vehicle connectors, which can conveniently and comprehensively detect the size of metal terminals, avoid detection blind spots, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal terminal size detection mechanism for vehicle connectors, comprising a mounting box and conductive components;

[0006] Mounting box: An internal belt conveyor is installed. Height adjustment components and actuation components are installed on the front and rear sides of the mounting box.

[0008] Wherein: the input end of the brush slip ring is electrically connected to the output end of an external PLC controller, and the output end of the brush slip ring is electrically connected to the input end of a belt conveyor.

[0009] Furthermore, the movable component includes a fixed ring, a movable frame, a first motor, a gear, and a rotating ring. A fixed ring is fixed to the center of the upper side of the mounting box. A first annular groove is formed at the upper end of the fixed ring, and a rotating ring is rotatably connected inside the first annular groove.

By setting two electric telescopic rods to drive two fastening plates to move, the metal terminal to be initially detected is clamped and fixed. Then, the fourth motor is started to rotate the front fastening plate, which drives the metal terminal to rotate, making it convenient for the camera to detect the bottom of the metal terminal.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This vehicle connector metal terminal size detection mechanism has the following advantages:

[0015] 1. The integrated design of the moving component and the shooting component allows the camera to move freely on a circular track. Combined with the tilt angle adjustment capability, this dynamic motion mechanism allows the camera to capture the metal terminal from all directions, including the upper surface, side wall contours and bottom hidden structures (such as grooves or curved parts) of the terminal, thereby overcoming the limitations of traditional fixed-view detection.

[0016] 2. The height adjustment component and the toggle component work together to automatically adjust the vertical height to accommodate terminals of different sizes. At the same time, the fixing component, driven by an electric telescopic rod and a motor, quickly clamps and rotates the terminals. This adaptive design not only reduces manual intervention (e.g., eliminating the need to manually change clamps or adjust equipment) but also ensures stable fixing and precise rotation of the terminals during the inspection process, facilitating data capture by the camera from the optimal angle. As a result, the inspection cycle is significantly shortened, and the risk of errors caused by human factors is reduced. Attached Figure Description

[0027] The working principle of the vehicle connector metal terminal size detection mechanism provided by this utility model is as follows: First, the vehicle connector metal terminal is transported to the detection station by a belt conveyor and then paused. When the height adjustment component is activated, the third motor drives the sprocket to drive the chain to rotate the threaded rods on both sides synchronously, so that the moving bar is vertically raised and lowered along the guide of the limit rod, thereby adjusting the height of the fixed component to accommodate terminals of different sizes. The fixed component pushes the connecting block and fastening plate to clamp the terminal through the electric telescopic rod, and the fourth motor drives the front fastening plate to rotate the clamped terminal to achieve multi-angle positioning of the terminal. During detection, the moving component is driven by the first motor to engage the gear with the fixed ring gear ring, driving the moving frame to move along the circular trajectory of the rotating ring. The shooting component adjusts the pitch angle of the camera on the connecting plate through the second motor driving the T-shaped column. Combining the circular movement of the moving frame and the rotation of the T-shaped column, the camera can perform multi-angle dynamic shooting around the terminal, covering the three-dimensional structure of the terminal's upper surface, side wall and bottom groove, completely eliminating the detection blind spot. After the detection is completed, the fixed component releases the terminal, and the belt conveyor moves the inspected terminal out and transports the new workpiece, forming a continuous automated detection process.
