Controller 8 is fixedly installed on rack 1, and controller 8 is used to control first servo motor 18, first cylinder 6 and second cylinder 7 work.
[0023] The feeding mechanism comprises a second servo motor 9 fixedly installed on the rack 1, an installation rack 10 fixedly installed at the output shaft end of the second servo motor 9, and a plurality of storage assemblies installed at the ends of the installation rack 10 and arranged in a circumferential array. The storage assembly comprises an annular ring 11 fixedly connected at the end of the installation rack 10, and a movable plate 12 penetrating through the annular ring 11, with elastic members 13 fixedly connected at the two sides of the movable plate 12 and at the other end of the annular ring 11. The upper surface of the movable plate 12 is provided with a strip-shaped anti-skid pattern 14, and a third servo motor 15 is fixedly installed on the rack 1, with an incomplete friction wheel 16 fixedly installed at the output shaft end of the third servo motor 15.
[0024] The annular ring 11 is provided with two spaced-apart mark lines 17, which can serve as position references. The capacitive sensor is placed in the annular ring 11, and the mark lines 17 are located at the side of the pins. The staff can refer to the mark lines 17 to place the capacitive sensor more accurately.
[0025] Working principle: The capacitive sensor is continuously placed on the annular ring 11, one end of the movable plate 12 limits the bottom of the capacitive sensor, the installation rack 10 is intermittently driven to rotate by the second servo motor 9, the annular ring 11 rotates synchronously with the installation rack 10, the capacitive sensor is intermittently driven to be above the two supporting plates 2 and stops for a period of time, during which the third servo motor 15 drives the incomplete friction wheel 16 to rotate, the incomplete friction wheel 16 rotates to contact the strip-shaped anti-skid pattern 14 and moves the movable plate 12 by friction, the movable plate 12 separates from the capacitive sensor, the elastic members 13 are stretched, and the capacitive sensor falls between the two supporting plates 2. When the incomplete friction wheel 16 separates from the strip-shaped anti-skid pattern 14, the elastic members 13 drive the movable plate 12 to reset.
[0026] Then the controller 8 controls the first air cylinder 6 to work, the first air cylinder 6 drives the pushing block 5 to move towards the two pins, when the gap between the two pins is small, the pushing block 5 applies an outward expansion force to the two pins, and the side plate 3 limits one side of the capacitive sensor.

Thus, the device can automatically calibrate the distance between the two pins of the capacitive sensor. After calibration is completed, the first servo motor 18 drives the side plate 3 to rotate one circle, the side plate 3 can push the capacitive sensor to slide between the two supporting plates 2 and move out of the device, and the staff takes it out. Then the first air cylinder 6 drives the pushing block 5 to reset, and the second air cylinder 7 drives the pressing plate 4 to reset.
