[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] See also Figure 1 and Figure 2As shown, the present invention provides an embodiment: an online piston pin length detection device, comprising a first conveyor belt 1, a second conveyor belt 2, and a third conveyor belt 3. The first conveyor belt 1, the second conveyor belt 2, and the third conveyor belt 3 are arranged in sequence from left to right. The second conveyor belt 2 is hingedly connected to the first conveyor belt 1 and the third conveyor belt 3 via a rotating shaft. A gantry 4 is provided on the upper surface between the front and rear support plates of the second conveyor belt 2. The gantry 4 is equipped with a detection member 5 for measuring the piston pin. By placing the piston pin on the first conveyor belt 1 for transmission and then transferring it to the second conveyor belt 2, the detection member 5 can detect the length and curvature of the piston pin. If the piston pin passes the test, it is transferred to the third conveyor belt 3 for further transmission. If it fails the test, the motor drives the second conveyor belt 2 to rotate, causing it to tilt outward, thereby screening the piston pin.

[0012] Please continue reading Figure 1 and Figure 2As shown, in one embodiment of the present invention, the detection component 5 includes a dual-output motor 51, and the dual-output motor 51 is embedded in the middle of the horizontal plate of the gantry 4.
