The screw drives the sliders to slide against each other on the inner side of the guide rail. The sliders slide against each other to assist in driving the clamping blocks to move against each other. At this time, the oxygen sensor body is placed between the slots of the clamping blocks. When the clamping blocks move inward, the slots can assist in clamping the oxygen sensor body. Since the slots are V-shaped, the inner inclined surface can be used to guide the oxygen sensor body to contact the oxygen sensor body, so that the oxygen sensor body is in a centered state, which is convenient for clamping oxygen sensor bodies of different sizes.

The motor A4 is connected to the frame 1, and the output end of the motor A4 is connected to the roller shaft of one of the guide rollers. Infrared gratings are symmetrically arranged on both sides of the discharge end of the feed conveyor belt 2. The conductive seat 6 is rotatably connected to the frame 1. A conductive head 8 is arranged on the conductive seat 6, and the conductive seat 6 is located between the feed conveyor belt 2 and the discharge conveyor belt 3. The conductive seat 6 symmetrically connects two mold seats 9, a socket 901 is arranged inside the mold seat 9, and the mold seat 9 is connected to the plug-in terminal, and the plug-in terminal is electrically connected to the conductive head 8. The clamping and pushing mechanism is connected to the frame 1, and the clamping and pushing mechanism includes a movable frame 11, a bidirectional module 12 and an elastic clamping assembly. The two movable frames 11 are respectively located on both sides of the feed conveyor belt 2 and the discharge conveyor belt 3. The movable frames 11 on both sides are respectively connected to two elastic clamping assemblies with the same movement direction. The bidirectional module 12 is connected to the frame 1 and simultaneously drives the movable frames 11 on both sides to move closer or farther away from each other. The elastic clamping assembly includes a connecting rod A13, a clamping plate 14, a slider 15, a connecting rod B16 and a tensioning spring 17. The clamping plate 14 is parallel to the movable frame 11, and the two connecting rods A13 are parallel to each other and rotate to connect the movable frame 11 and the clamping plate 14 at the same time. The slider 15 is slidably connected to the movable frame 11, and the connecting rod B16 is rotatably connected to the slider 15 and the clamping plate 14, and the connecting rod A13 and the connecting rod B16 are distributed in a V-shaped structure. The tensioning spring 17 is connected to the movable frame 11 and abuts the slider 15, so as to provide tensioning force for the clamping plate 14 to clamp the sensor through the tensioning spring 17. In the working state, the clamping and pushing mechanism pushes the sensor on the feed conveyor belt 2 into the die base 9 close to the side of the feed conveyor belt 2 and pushes out the sensor in the die base 9 close to the side of the discharge conveyor belt 3 and makes it fall on the discharge conveyor belt 3. The detection component is connected to the frame 1. The detection component includes a control frame 18, a movable plate 19 and a detector 20.

The detection result is displayed on the touch screen. After the detection is completed, motor B7 drives the conductive seat 6 to continue to rotate 90 degrees so that the detected sensor faces the discharge conveyor belt 3. At this time, the second loading is carried out. During the second loading process, the feed side clamp 14 pushes the sensor to be detected and clamps it into the mold base 9, while the two clamps 14 on the discharge side 14 push the detected sensor out of the mold base 9 and push it onto the discharge conveyor belt 3.
