Description

Technical Field

[0001] The utility model relates to the field of capacitor detection, in particular to a surface defect detection device for capacitors. Background Technique

[0002] Two conductors close to each other with a layer of non-conductive insulating medium in between form a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of the capacitor is numerically equal to the ratio of the amount of charge on one conductive plate to the voltage between the two plates. After the production of cylindrical capacitors is completed, it is necessary to detect the surface of the cylindrical capacitors to screen out the cylindrical capacitors that do not meet the standards.

[0003] Currently, a Chinese patent with the publication number CN219016117U discloses a surface defect detection device for the capacitor housing, including a device main body and a detection mechanism. A conveying mechanism is installed inside the device main body, a detection mechanism is connected above the device main body, and a control panel is installed outside the detection mechanism.

The isolation layer directly reduces the possibility of static electricity. The sliding rod moves up and down in the sliding groove according to the height of the capacitor until the soft pad clamp clamps the capacitor. The rotating plate below starts to rotate, the sliding block above moves back and forth outside the sliding plate, and the scanning laser scans the capacitor up and down, thus completing the use of the training equipment.

[0004] Most of the existing structures for detecting the surface defects of cylindrical capacitors only facilitate the rotational detection of the curved surface part of the cylindrical capacitor, and the two ends of the cylindrical capacitor cannot be effectively detected, easily causing missed detection of the surface defects of the cylindrical capacitor.

[0029] As shown Figures 1-5 in the figure, a surface defect detection device for a capacitor provided by an embodiment of the present utility model includes a bottom plate 1. A rotating mechanism 4 is arranged on the top of the bottom plate 1. A first motor 15 is arranged on the top of the bottom plate 1. A display screen 19 is fixedly connected to the front side of the top of the bottom plate 1. A bracket 3 is fixedly connected to the rear side of the top of the bottom plate 1. Cameras 2 are fixedly connected to both the rear side and the top of the inner wall of the bracket 3;

[0030] The rotating mechanism 4 includes a first roller 401, a turntable 402 and a second roller 403. The first roller 401 is arranged on the right side of the second roller 403. Both the first roller 401 and the second roller 403 are arranged on the top of the bottom plate 1.

[0031] In the technical solution of the present utility model, the distance between the first roller 401 and the second roller 403 is adjusted according to the diameter of the cylindrical capacitor to be defect-detected, so that the first roller 401 and the second roller 403 can rotate and hold up the cylindrical capacitor. At this time, control the second motor 10 to rotate. When the second motor 10 rotates, it can drive the second roller 403 to rotate. At this time, the second roller 403 can drive the cylindrical capacitor to rotate between the first roller 401 and the second roller 403. Then control the first motor 15 to rotate. When the first motor 15 rotates, it can drive the runner 16 to rotate through the output shaft, so that the turntable 402 rotates. At this time, the top camera 2 can detect the defects on the curved surface part of the cylindrical capacitor, and the bottom camera 2 can detect the defects at both ends of the cylindrical capacitor. Then the detection information is transmitted to the display screen 19 for display, which is convenient for the staff to observe the detection results, avoiding the problem that most of the existing structures for detecting the surface defects of cylindrical capacitors only facilitate the rotational detection of the curved surface part of the cylindrical capacitor, and the two ends of the cylindrical capacitor cannot be effectively detected, which is likely to cause missed detection of the surface defects of the cylindrical capacitor. It should be noted that the camera 2 is a mature technology that has been published, and is connected to the display screen 19 through the existing published wireless connection technology. The display screen 19 is internally provided with an existing published defect detection system, which is convenient for detecting and displaying the surface defects of the cylindrical capacitor.

[0036] In addition, please refer to Figure 4 and Figure 5 . A rotating cylinder 20 is fixedly connected to the bottom of the turntable 402. A rotating block 17 is fixedly connected to the top of the bottom plate 1. The rotating block 17 is rotatably connected to the inside of the rotating cylinder 20.
