[0001] The present invention relates to the technical field of capacitance detection, and specifically to a capacitance leakage and appearance detection device. Background Art

[0002] As a key component in electronic circuits, the performance and reliability of capacitors directly affect the quality of electronic devices. During the production process, capacitance leakage and appearance defects (such as breakage, deformation, etc.) of capacitors are common quality problems, and strict detection is required to ensure product qualification. Traditional detection methods mostly rely on manual visual inspection and manual testing, which have problems such as low efficiency, high labor intensity, high missed detection rate, and poor consistency, and are difficult to meet the requirements of modern large-scale production.

[0003] In the prior art, although some automated detection devices have been proposed, there are still many deficiencies. For example, Chinese Patent No. CN116046669B discloses a capacitor detection device and detection method, which uses a conveyor belt in cooperation with a simple clamping mechanism for detection. However, this device is prone to stacking and jamming during the capacitance feeding process, resulting in uneven feeding. At the same time, the appearance detection part of the capacitor lacks multi-angle adjustment detection and is difficult to comprehensively capture surface defects; the leakage detection module has a single structure and cannot perform multi-point repeated testing, and the reliability of the detection results is insufficient.

[0004] Therefore, there is an urgent need for a capacitance leakage and appearance detection device with high integration and excellent automation to solve the problems of unstable feeding, incomplete detection, and low reliability of leakage testing in the prior art, so as to improve the detection efficiency and product qualification rate and meet the refined requirements of modern industrial production.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The present invention provides a capacitance leakage and appearance detection device: 1. When detecting the leakage current of the capacitors after production and whether their appearance meets the standards, in order to avoid capacitor accumulation and blockage during the feeding process, the capacitors to be detected are uniformly put into the internal storage bin. According to the detection requirements, two partitions are dragged to orderly feed the capacitors to be detected inside the storage bin into the discharge bin. Then, several material distribution columns inside the discharge bin separate the squeezed and piled capacitors, facilitating sequential feeding through the feeding slot to the clamping seats on the second conveyor belt. When the capacitors carried on the clamping seats pass through the rubber pressing seat, the rubber pressing seat is pushed by the telescopic movement of the first electric telescopic rod to press the capacitors on the clamping seats, so that the capacitors are clamped and fixed to the clamping seats, avoiding accumulation and jamming during the feeding and conveying process of the capacitors, which may lead to uneven feeding.

The first conical extrusion seat rotates the capacitor by 360°. The CCD industrial camera takes pictures of the capacitor during the 360° rotation process, and then cooperates with the image processing module for processing to capture the surface image of the capacitor and identify and screen out the capacitors with damaged appearance and defects. The unqualified capacitor parts are driven by the contraction of the small electric telescopic rod to make the capacitor fall off, completing the multi-angle detection of the capacitor appearance and comprehensively capturing the surface defects.

[0015] 3. When detecting the leakage current of the capacitors on the arc-shaped grippers, the telescopic movement of the small telescopic electric rod corresponding to the top of the capacitor pushes the telescopic spring inside the sleeve, making the metal pin at one end of the telescopic spring contact the top of the capacitor to conduct electricity. The metal pin is electrically connected to the external high-voltage power supply. During the power-on process of the capacitor, the corresponding voltage detector is used to test the voltage and detect the leakage current value to determine whether the capacitor leaks electricity. At the same time, to ensure the accuracy of the capacitor detection, it can be moved and adjusted to the bottom of other remaining metal pins for inspection and testing, thus realizing multi-point repeated testing and improving the reliability of the detection results.

The feeding end of the inclined blanking chute 3 is placed at the bottom of the discharge opening 2012.

[0024] During specific use, when detecting the leakage and whether the appearance of the capacitors completed in production meets the standards, the capacitors need to be conveyed one by one to the conveying mechanism 4. In order to avoid the accumulation and blockage of capacitors during the feeding process, it is controlled by the set feeding mechanism 2. The capacitors to be detected are uniformly put into the storage bin 203. Then, according to the detection requirements, the two partition plates 202 are dragged, so that the capacitors to be detected inside the storage bin 203 are orderly fed into the discharging bin. Then, a number of material distribution columns 205 inside the discharging bin 204 separate the squeezed and piled capacitors, so as to facilitate the sequential feeding through the blanking slot 207 to the first conveyor belt 2011 for conveying, and reach the inclined blanking chute 3 through the discharge opening 2012 for orderly discharging.

[0025] The conveying mechanism 4 includes a conveying frame 401 fixedly connected to the top of the fixed table 1.

A first electric telescopic rod 408 is fixedly connected to the top of the installation frame 407. A rubber pressing seat 409 is fixedly connected to the telescopic end of the first electric telescopic rod 408.

[0026] During specific use, when transporting capacitors, to facilitate the orderly detection of capacitors, the capacitors fall from the inclined blanking chute 3 into the engaging seat 406 on the second conveyor belt 405. Then, when the capacitors carried by the engaging seat 406 pass through the rubber pressing seat 409, the rubber pressing seat 409 is pushed by the telescopic movement of the first electric telescopic rod 408 to press the capacitors on the engaging seat 406, so that the capacitors are clamped and fixed to the engaging seat 406 and are transported one by one to the appearance detection and sorting mechanism 5 for detection.

[0027] The appearance detection and sorting mechanism 5 includes an adjustment and fixing frame 501 fixedly connected to the top of the fixed table 1. One side of the top of the adjustment and fixing frame 501 is fixedly connected with a slide rail 502. One end of the top of the adjustment and fixing frame 501 is fixedly connected with a third driving motor 503. The driving end of the third driving motor 503 is fixedly connected with a lead screw 504. The outside of the lead screw 504 is threadedly connected with a moving slide seat 506 that is slidably connected to the slide rail 502. The bottom end of the moving slide seat 506 is fixedly connected with a second electric telescopic rod 507. The telescopic end of the second electric telescopic rod 507 is fixedly connected with an electric clamp 508. A blanking hole 509 is opened on the surface of the fixed table 1 directly opposite to the bottom position of the electric clamp 508. On both sides of the bottom end of the electric clamp 508, third electric telescopic rods 5010 are symmetrically arranged.

[0028] During specific use, to check whether there are defects on the surface of the capacitor, the third driving motor 503 rotates to drive the screw rod 504 to move the upper moving slide 506 to slide on the slide rail 502. The electric clamp 508 is adjusted to the top of the conveying mechanism 4. Then, the telescopic movement of the second electric telescopic rod 507 pushes the electric clamp 508 to clamp and lift the capacitor moving on the engaging seat 406 to between two symmetric rubber engaging clamps 5011. The small electric telescopic rod 5013 extends and retracts to push the first conical extrusion seat 5014 close to the capacitor. At the same time, the other end of the capacitor fits against one side of the second conical extrusion seat 5015 for clamping. The small electric telescopic rod 5013 is closed. Finally, the rotation of the fourth driving motor 505 drives the first main turntable 5018 to rotate. Under the rotation of the first main turntable 5018, the belt is driven to rotate, so as to facilitate the rotation of the first driven turntable 5017 to drive the second conical extrusion seat 5015 at one end of the transmission shaft 5016 to cooperate with the first conical extrusion seat 5014 to perform a 360° rotational appearance inspection on the capacitor. The CCD industrial camera 5012 takes pictures of the capacitor during the 360° rotation process, and then cooperates with the image processing module for processing to capture the surface image of the capacitor and identify and screen out the capacitors with appearance damage and defects. The unqualified capacitor parts are driven by the contraction of the small electric telescopic rod 5013 to drive the first conical extrusion seat 5014 to disengage from the capacitor. Then, the capacitor is discharged through the blanking hole 509 for unified collection. The capacitors with qualified appearance are clamped and moved to the feeding mechanism 6 by the electric clamp 508 under the cooperation of the third driving motor 503 and the screw rod 504, which facilitates the feeding mechanism 6 to move the capacitor to the bottom of the leakage detection mechanism 7 for further leakage detection.

The top of the feeding frame 608 is fixedly connected with a gear bar 609. The top of the gear bar 609 is meshed with a gear 6010. One side of the gear 6010 is fixedly connected with the driving end of a small driving motor 6011 fixedly connected to the top of the sliding adjustment seat 606; One end of the feeding rack 608 is fixedly connected with a fixed column 6012.

A fourth electric telescopic rod 6014 is movably connected between one ends of each group of arc-shaped clamping hands 6013.

[0030] During specific use, when detecting the leakage of the capacitor, it is necessary to make the power connection end of the capacitor contact the metal pin 705 for power-on detection of whether there is leakage. It is necessary to move the capacitor to the bottom of the leakage detection mechanism 7. By rotating the fifth driving motor, the second driving turntable 603 is driven to rotate. Under the rotation of the second driving turntable 603, the second driven turntable 604 is driven to rotate through the transmission belt 605, so that the transmission belt 605 slides along the X-axis under the bottom of the leakage detection mechanism 7 to different positions of the leakage detection structure, and multiple tests can be carried out under different leakage detection structures to ensure the accuracy of the detection. By rotating the small driving motor 6011, the gear 6010 is engaged with the rack 609, so as to facilitate the movement of the feeding rack 608 to move back and forth along the Y-axis on the limiting member 607, and move the capacitor clamped between the arc-shaped clamping hands 6013 to the bottom of the leakage detection mechanism 7 to facilitate contact with the metal pin 705 for power-on detection of whether there is leakage. After the leakage detection is completed, the arc-shaped clamping hands 6013 are opened by the telescopic movement of the set fourth electric telescopic rod 6014, so that the capacitor falls and unloads.

[0032] During specific use, when detecting the leakage of the capacitor on the arc-shaped clamping hand 6013, the telescopic spring 703 inside the sleeve 704 is pushed by the telescopic movement of the small telescopic electric rod 702 corresponding to the top of the capacitor, so that the metal pin 705 at one end of the telescopic spring 703 contacts the top of the capacitor to conduct electricity, and the metal pin 705 is electrically connected to the external high-voltage power supply. During the power-on process of the capacitor, the test voltage is detected by the corresponding voltage detector 707 to detect the leakage current value to determine whether the capacitor is leaking. When the voltage changes, the capacitor leakage indicator light 708 emits a red light. At the same time, to ensure the accuracy of the capacitor detection, it can be moved and adjusted to the bottom of other remaining metal pins 705 for inspection and testing, so as to maintain the accuracy of the capacitor detection. After the detection is completed, the capacitor controls the fourth electric telescopic rod 6014 through the PLC control panel 8 to adjust and open the arc-shaped clamping hand 6013 for blanking.

[0033] The PLC control panel 8 is fixedly connected to the top surface of the fixed table 1.
