Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic capacitor detection, in particular to a side drum detection device for an electrolytic capacitor. Background Art

[0002] The electrolytic capacitor side bulge detection device is a device specifically used to detect whether electrolytic capacitors have side bulge. During the use of electrolytic capacitors, due to internal chemical reactions, overheating, overvoltage or aging, the side of the capacitor shell may bulge. This phenomenon is called side bulge. Side bulge is an obvious sign that the electrolytic capacitor has failed or is about to fail. Therefore, timely detection and replacement of capacitors with side bulges is crucial to ensure the stable operation of electronic equipment. Among them, the more commonly used equipment is the electrolytic capacitor appearance inspection machine.

[0003] Electrolytic capacitor appearance inspection equipment is an automated or semi-automated inspection system used to check for appearance defects in electrolytic capacitors to ensure product quality meets standards. These defects may include side bulging, leakage, cracks, deformation, unclear markings, etc. However, during use, relying solely on images captured by industrial cameras to determine whether the capacitor shell has bulges can result in large errors and easily misjudgment, resulting in capacitors with slight side bulging being qualified as good products.

[0004] In response to the above problems, this utility model document proposes a side drum detection device for electrolytic capacitors. Utility Model Content

[0005] The utility model provides an electrolytic capacitor side bulge detection device, which solves the shortcomings of the prior art that only relies on images captured by industrial cameras to judge whether the capacitor shell has bulges, resulting in large errors and easy misjudgment, causing capacitors with slight side bulges to become good products.

[0006] The utility model provides the following technical solutions:

[0007] A device for detecting side bulge of an electrolytic capacitor, comprising:

[0008] A base, wherein an electric rotating base is fixedly installed on the top of the base, and a fixing groove for fixing the electrolytic capacitor to be tested is provided in the center of the top of the electric rotating base. A rotating plate is fixedly provided on one side of the base, and a high-definition camera for collecting images of the electrolytic capacitor shell is provided on the rotating plate. The high-definition camera transmits data with an external computer to observe the side bulge on the surface of the electrolytic capacitor shell;

[0009] The auxiliary judgment component is arranged on the base and is used to further detect the electrolytic capacitors that are not found to have side bulge, so as to prevent the capacitors with slight side bulge from becoming good products.

[0010] In one possible design, the auxiliary judgment component includes an L-shaped mounting frame fixedly provided on the top of the base, an electric push rod is fixedly provided on the top of the inner wall of the L-shaped mounting frame, and a detection cover is fixedly provided on the telescopic end of the electric push rod, and the detection cover is located directly above the fixed groove.

[0011] In a possible design, an annular mounting groove is provided on the inner wall of the detection cover, and a plurality of pressure sensors are embedded and installed in the annular mounting groove in an annular array. The plurality of pressure sensors are arranged in an arc surface that fits the annular mounting groove.

[0012] In a possible design, the inner circle radius of the detection cover is consistent with the outer circle radius of the shell of the electrolytic capacitor to be detected.

[0013] In a possible design, a buzzing alarm is fixedly installed on the outer wall of the detection cover to remind staff of the presence of side drum products, and the buzzing alarm is electrically connected to multiple pressure sensors.

[0014] In one possible design, a plurality of direct fill lights are embedded in a circular array at the bottom of the detection cover to illuminate the surface of the electrolytic capacitor shell to be detected, so that a shadow is generated at the side drum position for recording by a high-definition camera.

[0015] In a possible design, an L-shaped bracket for facilitating installation of the HD camera is fixedly provided on the back of the HD camera, and a slot for clamping and fixing the L-shaped bracket is provided on the top of the mounting plate.

[0016] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0017] In this application, when in use, the electrolytic capacitor to be tested is placed in the fixed slot on the top of the electric rotating seat to ensure that the capacitor is firmly fixed. The high-definition camera is installed on the card slot of the rotating plate through the L-shaped card bracket so that the surface of the capacitor shell can be clearly photographed. Then, the electric rotating seat is started to slowly rotate the capacitor in the fixed slot. At the same time, the direct fill light at the bottom of the detection cover is turned on to illuminate the surface of the capacitor shell, so that a shadow is generated at the side bulge position. The high-definition camera synchronously captures the image of the capacitor shell and transmits the data to an external computer. The staff preliminarily judges whether there is a side bulge phenomenon on the surface of the capacitor shell by observing the computer screen.

[0018] For capacitors that are not found to have side bulges during the preliminary inspection, the auxiliary judgment component is started, the electric push rod works, and the inspection cover is pushed down until it tightly covers the top of the capacitor shell. The pressure sensor starts working to detect the pressure changes of the capacitor shell on the inner wall of the inspection cover. If one or more pressure sensors detect abnormal pressure changes, it means that the capacitor has side bulges. At this time, the buzzing alarm sounds to alert the staff. The staff can further process or mark the capacitor with side bulges based on the alarm information.

[0019] The utility model has the following beneficial effects:

[0020] The utility model can realize efficient and accurate detection of the side bulge phenomenon of electrolytic capacitors, and perform secondary detection on suspected good products through the auxiliary judgment component, thereby avoiding missed detection and misjudgment, thereby ensuring product quality.

[0021] The utility model provides a direct fill light to illuminate the surface of the electrolytic capacitor shell to be inspected, so that a shadow is generated at the side drum position, thereby helping the high-definition camera to more accurately record the side drum situation, which helps to improve the inspection efficiency.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0030] Example 1

[0031] Please refer to Figure 1-4 A side drum detection device can efficiently and accurately detect whether electrolytic capacitors have side drum phenomenon, and further perform secondary inspection on suspected good products through auxiliary judgment components to ensure product quality, including:

[0032] Base 1, an electric rotating base 2 is fixedly installed on the top of the base 1, and a fixing slot 3 is provided in the center of the top of the electric rotating base 2 for fixing the electrolytic capacitor to be tested. By rotating the electric rotating base 2, the angle of the electrolytic capacitor can be easily adjusted so that the high-definition camera 5 can observe its shell surface from multiple angles. On one side of the base 1, a rotating plate 4 is fixedly provided, and a high-definition camera 5 is installed on the rotating plate 4. The high-definition camera 5 is used to collect high-definition images of the electrolytic capacitor shell and transmit data to an external computer via a data cable. The staff can observe the situation of the electrolytic capacitor shell surface in real time through the computer screen to determine whether there is a side bulge phenomenon;

[0033] In order to improve the accuracy of detection, the device is also provided with an auxiliary judgment component, which includes an L-shaped mounting frame 8 fixedly arranged on the top of the base 1, an electric push rod 9 fixedly arranged on the top of the inner wall of the L-shaped mounting frame 8, and a detection cover 10 fixedly arranged on the telescopic end of the electric push rod 9. The detection cover 10 is located just above the fixed groove 3. When a secondary inspection is required for a suspected good product, the electric push rod 9 will push the detection cover 10 down until it covers the top of the electrolytic capacitor shell;

[0034] An annular mounting groove 12 is provided on the inner wall of the detection cover 10, and a plurality of pressure sensors 13 of model LFC-05 are embedded and installed in an annular array in the annular mounting groove 12. These pressure sensors 13 are arranged in an arc surface that fits the annular mounting groove 12 and can be evenly distributed on the inner wall of the detection cover 10. When the detection cover 10 is covered on the electrolytic capacitor housing, if the capacitor has a side bulge phenomenon, the side bulge part will squeeze the detection cover 10, thereby causing the corresponding pressure sensor 13 to generate a pressure signal. In order to further improve the accuracy of the detection, the inner circle radius of the detection cover 10 is designed to be consistent with the outer circle radius of the electrolytic capacitor housing to be detected. In this way, the detection cover 10 can fit tightly on the capacitor housing, ensuring that the pressure sensor 13 can accurately sense the side bulge phenomenon.

[0035] A buzzing alarm 14 is also fixedly installed on the outer wall of the detection cover 10. The buzzing alarm 14 is electrically connected to multiple pressure sensors 13. When any pressure sensor 13 detects the side drum phenomenon, the buzzing alarm 14 will immediately sound an alarm to remind the staff that there is a side drum product.

[0036] This application can be used for electrolytic capacitor testing, and can also be used in other fields applicable to this application.

[0040] Please refer to Figure 2 and 4 In order to improve the camera effect, a plurality of direct fill lights 11 are embedded in a circular array at the bottom of the detection cover 10. These direct fill lights 11 can illuminate the surface of the electrolytic capacitor shell to be detected, so that a shadow is generated at the side drum position, thereby helping the high-definition camera 5 to record the side drum situation more accurately.

[0041] Please refer to Figure 3 In order to facilitate the installation of the high-definition camera 5, an L-shaped bracket 6 is fixed on the back of the high-definition camera 5. The top of the rotating plate 4 is provided with a slot 7 for fixing the L-shaped bracket 6. The high-definition camera 5 can be easily installed and removed through the snap-on fixing method.
