[0002] With the development of new energy vehicles, the comprehensive performance of the thermal management system is becoming increasingly important. Therefore, the manufacturing requirements for its components are also getting higher and higher.

[0003] However, for temperature sensors (see Figure 1 ), due to their complex structure, there is currently no automated and intelligent assembly or detection equipment for them. Therefore, the quality before use is difficult to guarantee.

Therefore, it is necessary to integrate optical detection and pre-oiling, and it should be adapted to an unmanned intelligent production line. Summary of the Invention

Two calibration pins are arranged on each calibration block to prevent the sensor from rotating and yawing. The height and angle of the calibration and detection unit are adjustable and are arranged facing the sensor on the calibration block. Parameters such as the height and roundness of the sensor can be detected.

[0010] Further, the fouling detection module includes a fouling detector arranged on a fouling detection frame, and the height and angle of the fouling detection frame are adjustable.

[0011] Further, the oiling module includes an oil injection assembly, an oil pressure tank, an oil injection controller, and an oil baffle; the oil injection assembly includes an oil injection gun and an oil injection seat.
