[0021] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings.

[0022] As Figure 1 shown, the embodiment of the present application provides an automotive connector pin detection mechanism, including a positioning mechanism 1 for positioning the connector and a detection mechanism 2 for detecting the connector pins on the positioning mechanism 1.

[0023] The positioning mechanism 1 includes a horizontal driving mechanism 11 that moves along the Y-axis direction, a rotating driving mechanism 12, and a carrier table 13 for positioning the connector. The driving end of the first driving mechanism is connected to the rotating driving mechanism 12, and the driving end of the rotating driving mechanism 12 is connected to the carrier table 13.

[0024] The detection mechanism 2 includes a biaxial driving mechanism 21, a fixed plate 22, a sensing device 23 for detecting the height of the pins inside the connector, and a camera assembly 24 for detecting the positions of the connector pins. The driving end of the biaxial driving mechanism 21 is connected to the fixed plate 22, and the sensing device 23 and the camera assembly 24 are respectively installed on the fixed plate 22.

[0025] Specifically, place the connector on the carrier table 13. The horizontal drive mechanism 11 drives the rotary drive mechanism 12 and the carrier table 13 to move along the Y-axis direction to the detection position. The first linear module 211 of the dual-axis drive mechanism 21 drives the second linear module 212 to move along the X-axis direction. The second linear module 212 drives the fixing plate 22 and the sensing device 23 to move along the X-axis direction. The second linear module 212 drives the fixing plate 22 and the sensing device 23 to move along the Z-axis direction. This enables the sensing device 23 to scan the height of the pin in the connector. Then, the rotary drive mechanism 12 drives the carrier table 13 to drive the connector to rotate 180 degrees. The dual-axis drive mechanism 21 drives the sensing device 23 again to scan the height of the pin in the connector. Through splicing calculation and analysis of multiple scan data, the "height" of the pin point relative to the reference plane is determined. The dual-axis drive mechanism 21 drives the fixing plate 22 to drive the camera assembly 24 to move along the X-axis and Z-axis to take pictures and detect the position of the pin in the connector, obtaining the height position of the pin installation.

[0026] In the above structure, the dual-axis drive mechanism 21 drives the sensing device 23 and the camera assembly 24 to move along the Z-axis and X-axis directions, enabling the sensing device 23 and the camera assembly 24 to detect the installation height and installation position of the pins in the automotive connector on the positioning mechanism 1 respectively. This connector pin detection mechanism 2 not only realizes automatic detection but also improves the detection efficiency and detection accuracy.

[0027] As Figure 1 shown, in one embodiment, the camera assembly 24 of the automotive connector pin detection mechanism includes a connection plate 241, a camera 242, and a light source 243. The camera 242 and the light source 243 are respectively installed on the connection plate 241, and the camera 242 is located directly above the light source 243. The lens of the camera 242 faces the light source 243, and the connection plate 241 is connected to the fixing plate 22.

[0028] Specifically, after the carrier table 13 drives the connector to move to the detection position, the dual-axis drive mechanism 21 drives the fixing plate 22 to drive the camera 242 and the light source 243 to move above the connector. The light source 243 illuminates the camera 242, and the camera 242 takes pictures and detects the installation position of the pins in the connector on the carrier table 13. This setting facilitates the automatic detection of the installation position of the pins in the connector, improving the detection efficiency and detection accuracy.

[0029] As Figure 1As shown, in one embodiment, the sensing device 23 of the automotive connector pin detection mechanism is a 3D line scan sensor. The 3D line scan sensor is used to scan the pins inside the connector. The hollow rotary platform 121 drives the carrier stage 13 to drive the connector to rotate 180 degrees, and then the 3D line scan sensor moves in the reverse direction to scan the pins inside the connector. The scanned data is stitched, calculated and analyzed, and the "height" of the pin point relative to the reference plane is determined according to the analysis result. This setting facilitates the automatic detection of the installation height of the pins of the connector, and also improves the detection efficiency and accuracy.

[0030] As Figure 1 shown, in one embodiment, the sensing device 23 of the automotive connector pin detection mechanism is a contact displacement sensor. Using a contact displacement sensor facilitates the detection of the height of the pins inside the connector.

[0031] As Figure 1 shown, in one embodiment, the dual-axis drive mechanism 21 of the automotive connector pin detection mechanism includes a first linear module 211 that moves in the X-axis direction and a second linear module 212 that moves in the Z-axis direction. A first support plate 213 is provided on the back of the second linear module 212, and the driving end of the first linear module 211 is connected to the first support plate 213. The first linear module 211 drives the second linear module 212 to drive the sensing device 23 and the camera assembly 24 to move in the X-axis direction, and the second linear module 212 drives the fixing plate 22 to drive the sensing device 23 and the camera assembly 24 to move in the Z-axis direction. This setting facilitates driving the sensing device 23 and the camera assembly 24 to move in the X-axis and Z-axis directions.

[0032] As Figure 1 shown, in one embodiment, a second support plate 214 is provided on the back of the first linear module 211 of the automotive connector pin detection mechanism, and the second support plate 214 is used to connect to an external frame. The provision of this second support plate 214 facilitates the fixation of the first linear module 211.

[0033] As Figure 1 shown, in one embodiment, the horizontal drive mechanism 11 of the automotive connector pin detection mechanism is a third linear module 111. This setting facilitates driving the hollow rotary platform 121 to drive the carrier stage 13 to move in the Y-axis direction.

[0034] As Figure 1 shown, in one embodiment, the rotary drive mechanism 12 of the automotive connector pin detection mechanism is a hollow rotary platform 121. This setting facilitates driving the carrier stage 13 to drive the connector to rotate at multiple angles.

[0035] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
