Description

Technical Field

[0001] The utility model relates to the technical field of capacitor sealing ring detection, in particular to a capacitor sealing ring detection device. Background Art

[0002] Capacitors are one of the basic components in electronic equipment and are widely used in power systems, communication equipment, household appliances and other fields. In order to ensure the stable performance and long service life of capacitors, their sealing performance is very important. The sealing ring cooperates with the cover plate to play a sealing role when the capacitor is sealed. However, the state of the sealing ring on the cover plate often affects the sealing condition. If the seal does not fit the cover plate, it will cause flanging, warping, etc., which will generally cause leakage. Therefore, during the production process, it is necessary to use a detection device to detect it to ensure the performance and service life of the capacitor.

[0003] Currently, most detection methods are mechanical and photoelectric. Mechanical detection usually requires direct contact with the sealing ring. Long-term or improper contact can easily cause damage to the surface of the sealing ring, thereby increasing the chance of damage to the sealing ring during detection. Photoelectric detection is easily affected by ambient light. When the lighting conditions are unstable, it will affect the detection results. If a part of the sealing ring is blocked by other components, it will be impossible to accurately identify the status of that part and it will be difficult to accurately identify all the details, resulting in false alarms and false detections during detection, reducing the detection effect. Utility Model Content

[0004] The purpose of the utility model is to provide a capacitor sealing ring detection device to solve the above-mentioned deficiencies in the technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a capacitor sealing ring detection device, comprising a detection platform, a support frame is fixedly connected to one side of the upper end surface of the detection platform, and a carrying plate is provided at the middle position of the upper end of the detection platform, the upper end surface of the carrying plate is equidistantly and evenly provided with a plurality of placement cavities, and the upper end of the support frame is provided with a detection component, the detection component comprises an outer cover arranged at the upper end of the carrying plate, a photoelectric sensor is installed on the inner surface wall of the outer cover, a laser scanner is installed on one side of the photoelectric sensor and located inside the outer cover, a positioning block used in conjunction with the photoelectric sensor is fixedly connected to the upper end surface of the carrying plate and on one side of the placement cavity, a rotary connecting seat is fixedly connected to the upper end surface of the detection platform and on one side of the carrying plate, a controller is installed on the rotary connecting seat, the lower end surface of the detection platform is fixedly connected to a supporting bottom box, a driving motor is installed in a placement groove reserved inside the supporting bottom box, and a driving shaft connected to the output end of the driving motor passes through the detection platform and is connected to the carrying plate.

[0006] The support frame is provided with a lifting assembly, and the lifting assembly includes a forward and reverse motor installed on the upper end surface of the support frame, and a slide groove is opened on the side wall of the support frame, and a screw rod is connected to the inside of the slide groove, one end of the screw rod passes through the support frame and is connected to the output end of the forward and reverse motor, and the external thread of the screw rod is connected to a slider embedded in the slide groove, and the end of the slider away from the slide groove is connected to a fixing rod, and the end of the fixing rod away from the slider is connected to the upper end surface of the outer cover.

[0007] Specifically, during inspection, the workpiece composed of the sealing ring cover plate to be inspected is placed in the placement cavity opened by the carrying plate, and then the corresponding switch on the controller is pressed to turn on the forward and reverse motors, the drive motor, the photoelectric sensor and the laser scanner in sequence. The forward and reverse motors drive the screw to rotate. During the rotation, the slider cooperates with the screw thread, and the slider moves down in the slide groove, driving the outer cover to a suitable height. The carrying plate is then driven to rotate by the drive motor. During the rotation, the position of the workpiece is detected by the photoelectric sensor. When the photoelectric sensor detects that the positioning block enters directly below, it transmits a signal to the controller. The controller sends a stop signal to the drive motor, and the carrying plate stops rotating. A line laser emitted by the laser scanner is used to perform a multi-directional comprehensive scan of the workpiece. The workpiece is scanned to form a three-dimensional stereogram. The scan data is transmitted to an external computer and compared with the height difference between the height of the circled specified range and the reference plane to determine whether it is a qualified product. The results of the inspection are displayed on the display screen on the controller.

[0008] Preferably, the supporting plate is provided with an ejection structure, and the ejection structure includes an elastic connecting plate arranged inside a cavity opened on the inner wall of the supporting plate, and the upper end surface of the elastic connecting plate is equidistantly and evenly connected with connecting columns matching the number of placement cavities, and the upper end surface of the connecting column is connected to a placement disc, and the placement disc is embedded inside the placement cavity.

[0009] Preferably, a position-limiting connection structure is provided on the outer side of the elastic connection plate, and the position-limiting connection structure includes a fastening component and a position-limiting component.

[0010] Preferably, the limiting assembly includes a block groove opened on the inner wall of the carrying plate, a moving block is embedded in the block groove, one end of the moving block is connected to the elastic connecting plate, and the upper end face of the moving block is fixedly connected to a connecting rod, the upper end face of the connecting rod is fixedly connected to a top block, and an embedding groove is opened on the outside of the top block and on the upper end face of the carrying plate.

[0011] Preferably, the fastening assembly includes a groove opened on the inner wall of the supporting plate and located on one side of the embedding groove, the outer side of the supporting plate is connected with a bolt, one end of the bolt passes through and extends to the inside of the groove and is connected with a clamping block, and the outer wall of the top block is provided with a clamping groove adapted to the clamping block.

[0012] Through the above technical solution:

[0013] After inspection, first take a special tool and insert one end of it into the socket opened at the end of the bolt, then screw the tool to loosen the bolt. While screwing, the blocking block moves out of the blocking slot. After the fixation is released, the spring force of the elastic connecting plate is used to move the plate body of the elastic connecting plate upward. At this time, the moving block moves upward in the block slot. At the same time, the top block connected by the connecting rod moves out of the embedding slot, and the placement disc connected by the connecting column moves out of the placement cavity. This operation can move the inspected workpiece out of the placement cavity, thereby increasing the workpiece removal space, avoiding the situation where manual picking is used, resulting in a high removal difficulty coefficient due to the limited space of the placement cavity, enhancing the convenience of workpiece removal, and also preventing the disadvantage of wear on the sealing ring during removal due to the small space of the placement cavity, ensuring the integrity of the sealing ring and the sealing performance of the capacitor.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. By setting up a photoelectric sensor, a laser scanner and a positioning block, the detection device uses a laser ranging method to detect the sealing condition of the sealing ring on the cover plate. During the detection, a line of laser emitted by the laser scanner is used to scan the sealing ring. The scanning forms a three-dimensional stereo image, which can show the overall shape and structure of the sealing ring, so that it can detect possible cracks, dents and other minor defects in the sealing ring, thereby improving the detection accuracy. In addition, the laser ranging does not require direct contact with the capacitor sealing ring, avoiding physical damage or deformation that may occur during the mechanical detection process, ensuring the integrity of the sealing ring after detection, and is not affected by ambient light during detection. It can be detected under unstable lighting conditions, ensuring the reliability of the detection device when detecting in different environments and improving the detection effect.

[0016] 2. By setting up the ejection structure, the carrier plate has an ejection function. After inspection, the workpiece can be moved out of the placement cavity, which increases the workpiece removal space and avoids the situation where manual picking makes it difficult to remove the workpiece due to the limited space of the placement cavity. It enhances the convenience of workpiece removal and prevents the disadvantage of wear on the sealing ring during removal due to the small space of the placement slot, thereby ensuring the integrity of the sealing ring and the sealing performance of the capacitor.
