With the rapid development of the automobile industry, the testing requirements for its related products are constantly changing. For example, poor joint contact of electronic control unit，and poor contact between switch joints of electric oil pump circuit in air flow sensor connectors，can lead to abnormal engine start; The wire disconnection of the power supply plug of the electronically controlled fuel injection valve of the engine causes the cylinder not to work. Therefore, considering the special condition of the automobile, the circuit under important working conditions can still work normally in the design of automobile connectors nowadays.
Therefore, in the initial design of the Pin needle, the special requirement loop pin needle will be 0.8mm-1.2mm higher than the other Pin; In addition to the original appearance and positivity detection, the pin height difference detection requirement is added to the traditional connector detection. This is to say, in addition to the 2D detection requirements in the plane XY direction, the Z direction is also added to and thus become the 3D detection requirements.
3DPIXA technology + characteristic dome light + professional image processing software + high-precision shifting platform.
Detection accuracy of camera:
0.015mm in X and Y direction; 0.003mm in Z direction;
System repetition accuracy: 6um;

Solution system advantages：
1.The 3D system adopts linear scanning binocular technology; it can detect and inspect all Pin needles in the slot of the connector; there is no so-called blind area of other detection methods; the image quality and accuracy are guaranteed by the one-time imaging.
2.The system has a fast speed, which can reach the detection and inspection speed of 0.58m/s. It can easily realize the Inline detection requirements of general needle insertion production line with the high-speed calculation GPU.
3.The system has good stability and can operate continuously for 7*24 hours in harsh industrial production environment because of the verifications of various working conditions of multiple production lines.
using the high stability and high standards 3D Pin needle detection system can bring customers a products all in one inspection, it avoids the pass of a problem part, all kinds of problems caused by poor contact of automobile electric control system caused by Pin position deviation/offset and too high or too low height are effectively avoided，the reliability of high grade circuit in emergency condition is guaranteed.
