When the first driving motor 203 drives the threaded shaft 202 to rotate, the clamping plate 204 can move along the threaded shaft 202;

[0030] like Figure 5 As shown, the support unit 1 includes a carrying platform 101 and a supporting leg 102 installed at the bottom of the carrying platform 101. The arrangement of the supporting leg 102 provides support for the stable operation of the entire detection device.

[0031] like Figure 2 As shown, the clamping unit 2 further includes a rubber pad 206 installed on the inner wall of the clamping plate 204. The rubber pad 206 is provided to prevent the clamping plate 204 from directly contacting the single-layer ceramic capacitor and causing damage.

[0033] When it is necessary to clamp single-layer ceramic capacitors of different sizes, after placing the single-layer ceramic capacitor on the conveyor belt 301, the second drive motor 302 drives the conveyor belt 301 to rotate, so that the single-layer ceramic capacitor follows the conveyor belt 301 and moves to the bottom of the gantry 201, and the first drive motor 203 drives the threaded shaft 202 to rotate. Since the threaded shaft 202 is provided with two sections of threads with opposite rotation directions, the two clamping plates 204 can move along the threaded shaft 202 towards each other until the rubber pad 206 contacts the side wall of the single-layer ceramic capacitor and stops. At this time, the clamping of the single-layer ceramic capacitor is completed. Example 2

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a detection device for production of single-layer ceramic capacitors includes a support unit 1, a conveying unit 3 disposed in the support unit 1, a clamping unit 2 disposed above the support unit 1, and a detection unit 4 disposed inside the clamping unit 2;

[0041] like Figure 3 As shown, the detection unit 4 also includes a limiting washer 405 installed on the inner side wall of the fixed groove, and the limiting washer 405 is sleeved on the peripheral side of the screw rod 401. The setting of the limiting washer 405 prevents the moving part 403 from colliding with the inner side wall of the fixed groove during the movement of the screw rod 401.

[0042] When it is necessary to clamp single-layer ceramic capacitors of different sizes, after placing the single-layer ceramic capacitor on the conveyor belt 301, the second drive motor 302 drives the conveyor belt 301 to rotate, so that the single-layer ceramic capacitor follows the conveyor belt 301 and moves to the bottom of the gantry 201, and the first drive motor 203 drives the threaded shaft 202 to rotate. Since the threaded shaft 202 is provided with two sections of threads with opposite rotation directions, the two clamping plates 204 can move along the threaded shaft 202 towards each other until the rubber pad 206 contacts the side wall of the single-layer ceramic capacitor and stops.
