[0002] The function of the crankshaft position sensor is to determine the position of the crankshaft, that is, the angle of rotation of the crankshaft. It is one of the most important sensors in the automobile control system. It is a cylinder identification and positioning device that inputs the camshaft position signal to the ECU to determine the basic ignition timing.

[0003] The crankshaft position sensor is often tested before waterproofing treatment, so it is often manually removed and simulated tested after the circuit board is installed. Manual testing is prone to misjudgment, omission, and wrong judgment, and is easy to damage the circuit board and increase labor costs. Summary of the Invention

[0010] S4, fixed fixture sent back;

[0011] Using the above technical solution, the fixing fixture is provided with 4 workpiece slots, and the 4 crankshaft position sensors are installed on the fixing fixture in sequence through the workpiece slots. The detection block is adjusted to the preset position by adjusting the terminal block. The detection block is provided with a detection terminal and the voltage signal is fed back through the detection terminal. The fixing fixture is transmitted to the signal disk mechanism through the moving frame. The detection block is moved to the upper surface of the crankshaft position sensor by the action of the cylinder, so that the detection terminal is connected to the contact of the crankshaft position sensor. The signal disk mechanism simulates the rotation of the signal disk on the motor.

When the fixed fixture is transported to the first lifting plate, the crankshaft position sensor is taken out from the fixed fixture by the picking mechanism, and the qualified products are placed on the output conveyor belt, and the unqualified products are placed in the recycling box for easy classification. After taking out, the fixed fixture returns to the starting position via the first lifting plate, the fixture return belt and the second lifting plate in turn to facilitate the installation of the undetected crankshaft position sensor, thereby realizing the purpose of automatic detection and picking of the crankshaft position sensor, saving labor costs and improving production efficiency.

[0012] The present invention is further configured such that a steering rod and a cylinder are provided on the wiring frame, a steering block and / or a universal joint is provided on the steering rod, the cylinder is connected to the wiring frame via the steering block and / or the universal joint, the detection block is connected to the cylinder in a detachable manner, the detection block moves toward the direction of the fixing fixture through the action of the cylinder transmission, and the detection block is arranged above the fixing fixture.
