[0012] Preferably, the connector pin detection and correction system further comprises a limiting mechanism, wherein the limiting mechanism has a limiting surface, the limiting surface is located above the connector pin, and is suitable for limiting the connector pin in the vertical direction.

[0013] Preferably, the limiting mechanism comprises a limiting frame and a second driving member, the limiting surface is arranged on the limiting frame, the second driving member drives the limiting frame to move, and the limiting frame drives the limiting surface to move to a set position away from the connector pin.

[0017] S3. The limiting mechanism moves away from the connector Pin;

[0018] S4. The detection device detects one of the pins on the connector pin, and if the detection is qualified, the next pin is detected;

[0019] S5. If the test fails, the calibration device calibrates the unqualified pins after the test.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. The connector pin detection and correction system of the present invention includes a detection platform, a detection device and a correction device. The detection platform is suitable for placing the connector pin; the detection device includes a shooting component and a first driving mechanism, the shooting component is arranged on the first driving mechanism and is located on one side of the connector pin; the correction device includes a correction piece and a second driving mechanism, and the correction piece is connected to the second driving mechanism.

[0022] When in use, the shooting component is driven by the first driving mechanism to move to a set position to detect the position of the connector pin; the correction member is driven by the second driving mechanism to correct the position of the connector pin. By setting up a detection device, unqualified connector pins are detected, and by setting up a correction device, unqualified connector pins are corrected. The pin detection and correction system of the present invention realizes automated detection and correction, overcoming the problems of low operating efficiency, missed detection, inaccurate detection and correction caused by manual detection and correction with a ruler.

[0023] 2. In the connector pin detection and correction system of the present invention, a receiving groove is arranged at the end of the correction piece, and the receiving groove is a tubular structure. This tubular structure can accommodate the connector pin, and then the connector pin is corrected according to the detection information.

The limiting mechanism has a limiting surface, which is located above the connector pin and is suitable for limiting the connector pin in the vertical direction.

[0025] When in use, the limiting mechanism first acts to move the limiting surface toward the connector Pin needle until the limiting surface abuts against the upper surface of the connector Pin needle, so that the connector Pin needle cannot move in the vertical direction. Then the first clamping assembly starts to act, and multiple claws support the inner ring of the connector Pin needle to position the connector Pin needle. Then the limiting mechanism acts again to move the limiting surface away from the connector Pin needle to facilitate detection by the detection device and correction by the correction device.

[0026] Due to the manufacturing deviation of the inner ring of the connector Pin, the connector Pin moves in the vertical direction after the claws support the inner ring of the connector Pin, resulting in the inability of various parts of the connector to fit with the detection platform, that is, the detection reference and the correction reference are shifted. By setting a limit mechanism, the problem of the inner ring of the connector Pin moving and misaligned when the claws support the inner ring of the connector Pin is solved, ensuring that the detection reference and the correction reference remain unchanged after the claws support the connector Pin, and the detection and correction are more accurate.

[0038] The end of the correction member 5 is provided with a receiving groove, which is a tubular structure suitable for receiving the connector pin 2. This tubular structure can receive the connector pin 2, and then the connector pin 2 is corrected according to the detection information. The correction member 5 has a very simple structure and effectively realizes the correction of the connector pin 2 by controlling the second driving mechanism 4.

[0039] The shooting component includes: a first camera and a second camera. The first camera is a 3D laser profile sensor, which determines whether the connector Pin 2 is tilted in space; the second camera is an industrial array camera, which is suitable for determining whether the connector Pin 2 has a deviation in the height direction.

[0044] When in use, the limiting mechanism first acts to move the limiting surface toward the connector Pin needle until the limiting surface abuts against the upper surface of the connector Pin needle, so that the connector Pin needle cannot move in the vertical direction. Then the first clamping assembly starts to act, and multiple claws support the inner ring of the connector Pin needle to position the connector Pin needle. Then the limiting mechanism acts again to move the limiting surface away from the connector Pin needle to facilitate detection by the detection device and correction by the correction device.

[0045] Due to the manufacturing deviation of the inner ring of the connector Pin, the connector Pin moves in the vertical direction after the claws support the inner ring of the connector Pin, resulting in the inability of various parts of the connector to fit with the detection platform, that is, the detection reference and the correction reference are shifted.
