[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0026] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-2As shown, an electrical connector inspection mechanism is provided, including a workbench 1, a positioning component 2 disposed on the workbench 1, and a vision inspection component 3. The positioning component 2 includes a placement platform 21, the top of which has a contour groove 22 that matches the electrical connector. One side of the contour groove 22 penetrates the placement platform 21 and forms a notch 23, through which the connector's terminals are exposed outside the placement platform 21. The vision inspection component 3 includes a CCD camera 31 facing the notch 23. The contour groove 22 is used to uniformly fix the electrical connectors in the batch to be inspected. The connectors to be inspected are placed on the workbench 1 with the same reference, reducing deviations during photographic inspection. The CCD camera 31 acquires assembly images of the connector terminals, and image comparison is used to determine whether the assembly distribution of the product is incorrect. This saves on training inspectors and avoids the problem of inconsistent inspection standards. Inspectors only need to perform the loading and unloading of electrical connectors, which simplifies the inspection process and improves inspection efficiency. Specifically, the electrical connection includes the main housing, and an insulating sleeve and a rear cover that are sequentially installed into the terminals of the main housing. Distributed installation refers to the assembly sequence of the insulating sleeve and the rear cover. When the rear cover is located between the insulating sleeve and the main housing, the product is judged as defective; when the insulating sleeve is located between the rear cover and the main housing, the product is judged as good. This embodiment also requires an industrial computer (not shown in the figure) and a display screen (not shown in the figure). The industrial computer is equipped with an image acquisition unit, an image processor, and a comparison database. The image acquisition unit is electrically connected to the CCD camera 31 and is used to receive the terminals of the electrical connector mounted on the placement platform 21. The comparison database contains preset control groups that conform to the assembly standards. After receiving the actual captured image, the image processor compares it with the control groups in the comparison database. The comparison result is fed back to the inspector through the display screen. Compared with the conventional method of visually observing the object and work standards, this greatly reduces the time for subjective judgment, thereby improving inspection efficiency.

[0030] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes a first support 24, and the placement platform 21 is inclinedly mounted on the workbench 1 via the first support 24. Specifically, one end of the placement platform 21 with a notch 23 is inclined upward and faces the operating side of the workbench 1, thereby facilitating manual handling of products.

[0031] In one embodiment of this utility model, such as Figures 1-2 As shown, the positioning component 2 further includes a pair of gripping claws 25 and a drive member 26 capable of driving the pair of gripping claws 25 to open and close. The pair of gripping claws 25 are disposed opposite each other on both sides of the placement stage 21 and can act on the interface end of the electrical connector. By using the pair of gripping claws 25 to act on the electrical connector, the detection deviation caused by the relative movement between the electrical connector and the placement slot during the detection process is reduced.

[0032] In one embodiment of this utility model, such as Figures 1-2 As shown, the driving component 26 is a pneumatic finger fixed to the end of the placement platform 21 away from the notch 23, and a pair of gripping claws 25 are respectively connected to a pair of piston rods of the pneumatic finger. The structure is simple and easy to install.

[0033] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes a button assembly and a solenoid valve. The button assembly enables the solenoid valve to be electrically connected or disconnected. The pneumatic finger is connected to an external air source through the solenoid valve. The button assembly is a mechanical button connected in series on the circuit board of the solenoid valve. Pressing the mechanical button opens and closes a pair of gripping claws 25, making operation simple and convenient.

[0034] In one embodiment of this utility model, such as Figures 1-2 As shown, the clamping claw 25 has a vertically arranged first clamping end face 251 and a horizontally arranged second clamping end face 252 at its clamping end. The first clamping end face 251 can act on the interface end of the electrical connector in the horizontal direction, and the second clamping end face 252 can act on the interface end of the electrical connector in the vertical direction. Specifically, the clamping claw 25 has a strip-shaped structure, with the connecting end connected to the pneumatic finger, and a vertically arranged protrusion extending inward from the clamping end. The first clamping end face 251 is formed on the inner side of the clamping claw 25, and the second clamping end face is formed on the bottom end face of the protrusion. Furthermore, the inner end of the protrusion has a chamfered edge facing the insertion end of the electrical connector, which helps to reduce interference between the clamping claw 25 and the electrical connector.

[0035] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes a second bracket 32, the bottom end of which is movably connected to the worktable 1 and the top end of which is fixedly connected to the CCD camera 31.

[0036] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes a tightening screw 33. The worktable 1 has a hollow slot 11 corresponding to the second bracket 32. The bottom of the second bracket 32 ​​has an arc-shaped hole 321. One end of the tightening screw 33 passes through the arc-shaped hole 321 and the hollow slot 11, and its end is threaded into a nut. By loosening the nut, the second bracket 32 ​​can move relative to the worktable 1. The position of the CCD camera 31 on the worktable 1 can be adjusted using the hollow slot 11, and the orientation angle of the CCD camera 31 can be adjusted using the arc-shaped hole 321, thereby broadening the applicability of this embodiment.

[0037] In one embodiment of this utility model, such as Figures 1-2As shown, it also includes a light source assembly 12, which is disposed on the worktable 1 with its light-emitting end facing the notch 23. Specifically, the light source assembly 12 is an LED lamp disposed on the worktable 1.
