[0070] In the related art, the appearance inspection of capacitors is carried out by manually inspecting whether the capacitor is leaking, whether the aluminum shell is deformed, and whether the rubber plug is properly engaged. However, the inspection by manual means has the problem of low inspection efficiency.

[0071] In order to solve the above problems, the present invention provides an automated device and method for capacitor appearance inspection, wherein a first acquisition module collects an image of a cover plate of the capacitor, a second acquisition module collects an image of a through hole of the cover plate, and a third acquisition module collects an image of an aluminum shell of the capacitor. A control module determines whether the capacitor is qualified based on the images collected by the first acquisition module, the second acquisition module, and the third acquisition module, thereby realizing automated inspection of the capacitor appearance, reducing labor, and improving inspection efficiency.

[0072] The following describes in detail the automated device and method for capacitor appearance detection provided by the embodiments of the present invention in conjunction with specific embodiments.

[0073] Figure 2 A schematic diagram of the structure of an automated device for capacitive appearance detection provided by an embodiment of the present invention; Figure 3 for Figure 2 Schematic diagram of the partial structure of the automated equipment used for capacitor appearance inspection.

[0074] like Figure 2 and Figure 3As shown, an embodiment of the present invention provides an automated equipment for capacitor appearance inspection, including a frame 10 and a first loading module, a correction module 20, a second loading module 30, a rotating worktable 40, a first acquisition module 51, a second acquisition module 52, a third acquisition module 53, a first collection box 54, a second collection box 55 and a control module 60 installed on the frame 10.

[0075] The correction module 20 is located downstream of the first loading module, and is used to correct the first pin 104 and the second pin 105 of the capacitor 100 provided by the first loading module; the second loading module 30 is located downstream of the correction module 20, and is used to transfer the corrected capacitor 100 to the rotating workbench 40.

[0076] Six workstations are arranged at equal intervals along the circumferential direction on the outer side of the rotating worktable 40. The second loading module 30, the first acquisition module 51, the second acquisition module 52, the third acquisition module 53, the first collection box 54 and the second collection box 55 are arranged in sequence on the six workstations. The second loading module 30, the first acquisition module 51, the second acquisition module 52, the third acquisition module 53, the first collection box 54 and the second collection box 55 are all communicatively connected with the control module 60. The first acquisition module 51 is used to acquire an image of the cover plate 103 of the capacitor 100, the second acquisition module 52 is used to acquire an image of the through hole of the cover plate 103, and the third acquisition module 53 is used to acquire an image of the aluminum shell 101 of the capacitor 100. The control module 60 is used to determine whether the capacitor 100 is qualified according to the images acquired by the first acquisition module 51, the second acquisition module 52 and the third acquisition module 53. The first collection box 54 is used to collect unqualified capacitors 100, and the second collection box 55 is used to collect qualified capacitors 100.

[0077] When the capacitor 100 leaks, the leaked liquid will remain on the cover 103. The image of the cover 103 of the capacitor 100 is collected by the first acquisition module 51, and the image collected by the first acquisition module 51 is transmitted to the control module 60.

[0078] The control module 60 may be a host computer. The control module 60 stores a first training set, and determines whether the capacitor 100 is leaking by extracting color features from the image captured by the first acquisition module 51 and comparing them with the first training set. The first training set includes a first qualified color library and a first unqualified color library. The first qualified color library is the color on the image of the cover 103 of the qualified capacitor 100, and the first unqualified color library is the color on the image of the cover 103 of the leaking capacitor 100 that does not belong to the first qualified color library.

[0079] In an optional embodiment, after the capacitor 100 leaks, white liquid will appear on the cover 103. The colors in the first qualified color library include black, and the colors in the first unqualified color library include white. When the control module 60 extracts color features from the image acquired by the first acquisition module 51, the extracted features are compared with the first training set. If the extracted color features all belong to the first qualified color library, the capacitor 100 does not leak, that is, the capacitor 100 is a qualified capacitor; if the extracted color features partially belong to the first unqualified color library, the capacitor 100 leaks, that is, the capacitor 100 is an unqualified capacitor.

[0080] The first training set can be obtained as follows: first, obtain an image library of the cover 103 of the qualified capacitor 100 and an image library of the cover 103 of the leaking capacitor 100, the number of images in these two image libraries being greater than 100, then extract color features, and finally obtain a first qualified color library and a first unqualified color library through an algorithm program.

[0081] When the rubber plug 102 is not engaged in place, there will be no rubber plug 102 in the through hole of the cover plate 103. The image of the through hole of the cover plate 103 is collected by the second collection module 52, and the image collected by the second collection module 52 is transmitted to the control module 60.

[0082] The control module 60 stores a second training set. By extracting color features from the image acquired by the second acquisition module 52 and comparing the image with the second training set, it is determined whether the rubber plug of the capacitor 100 is engaged in place.

[0083] The second training set includes a second qualified color library and a second unqualified color library. The second qualified color library is the colors on the image of the through hole of the cover plate 103 of the qualified capacitor 100, and the second unqualified color library is the colors on the image of the through hole of the cover plate 103 of the capacitor 100 that is not properly engaged that do not belong to the second qualified color library. The process of obtaining the second training set is similar to the process of obtaining the first training set, and will not be described here.

[0084] In an optional embodiment, after the rubber plug of capacitor 100 is not engaged, there is no rubber plug 102 in the through hole of cover plate 103, and the color on the image is black. The color of rubber plug 102 is white. The colors in the second qualified color library include white, and the second unqualified color library includes black. When the control module 60 extracts color features from the image acquired by the second acquisition module 52, the extracted features are compared with the second training set. If the extracted color features all belong to the second qualified color library, the rubber plug of capacitor 100 is engaged in place, which means that capacitor 100 is a qualified capacitor; if the extracted color features partially belong to the second unqualified color library, the rubber plug 102 of the capacitor is not engaged in place, which means that capacitor 100 is an unqualified capacitor.

[0085] After the capacitor 100 is deformed, the shape of the aluminum housing 101 will change. The image of the aluminum housing 101 of the capacitor 100 is collected by the third collection module 53 and the image collected by the third collection module 53 is transmitted to the control module 60 .

[0086] The control module 60 stores a third training set. By extracting color features from the image acquired by the third acquisition module 53 and comparing the image with the third training set, it is determined whether the capacitor 100 is deformed.

[0087] The third training set includes a qualified shape library and an unqualified shape library. The qualified shape library is the shapes on the image of the aluminum shell 101 of the qualified capacitor 100, and the unqualified shape library is the shapes on the image of the deformed aluminum shell 101 of the capacitor 100 that do not belong to the qualified shape library.

[0088] In an optional embodiment, after the capacitor 100 is deformed, the shape of the aluminum housing 101 is an irregular curved shape. The qualified shape library includes regular curved shapes, and the unqualified shape library includes irregular curved shapes. When the control module 60 extracts shape features from the image acquired by the third acquisition module 53, the extracted features are compared with the third training set. If the extracted shape features all belong to the qualified shape library, the capacitor 100 is not deformed, that is, the capacitor 100 is a qualified capacitor; if the extracted shape features partially belong to the unqualified shape library, the capacitor 100 is deformed, that is, the capacitor 100 is an unqualified capacitor.

[0089] The automated equipment for capacitor appearance inspection provided by the embodiment of the present invention collects images of the cover plate 103 of the capacitor 100 through the first acquisition module 51, the second acquisition module 52 collects images of the through holes of the cover plate 103, and the third acquisition module 53 collects images of the aluminum shell 101 of the capacitor 100. The control module 60 determines whether the capacitor 100 is qualified based on the images collected by the first acquisition module 51, the second acquisition module 52, and the third acquisition module 53, thereby realizing automated inspection of the capacitor appearance, reducing labor, and improving inspection efficiency. In addition, compared with the manual method, the automated equipment for capacitor appearance inspection provided by the embodiment of the present invention can also improve the accuracy of capacitor appearance inspection and reduce production costs.

The six fixed jaws 43 are arranged in sequence at equal intervals in the circumferential direction of the circular turntable 42. Each fixed jaw 43 is used to fix the capacitor 100 transmitted by the second loading module 30.

[0091] The fixed jaw 43 is a jaw that can fix the aluminum housing 101 of the capacitor 100. The fixed jaw 43 is fixed on the round turntable 42. The fixed jaw 43 is in communication connection with the control module 60, and the control module 60 is used to control the fixed jaw 43 to be loosened or clamped.

The third fill light 533 and the magnet 532 are fixed on the lifting rod 531. The lifting rod 531 can slide on the axis of the aluminum housing 101. The magnet 532 is used to adsorb the first pin 104 and the second pin 105.

[0105] The two third cameras 534 are fixed on the third fixing frame, the two third cameras 534 are symmetrically arranged with respect to the axis of the aluminum housing 101, the two third cameras 534 are in communication connection with the control module 60, the two third cameras 534 are used to collect images of the aluminum housing 101 of the capacitor 100, and the third fill light 533 is used to fill light for the two third cameras 534. In this arrangement, the image of the aluminum housing 101 of the capacitor 100 can be obtained.

[0106] The lenses of the two third cameras 534 are aligned with the side walls of the aluminum housing 101 of the capacitor 100 .

[0107] There are multiple third fill lights 533, and the multiple third fill lights 533 are arranged around the two third cameras 534. The multiple third fill lights 533 can improve the clarity and brightness of the image collected by the third camera 534.

The lifting rod 531 is fixedly connected to the cylinder, and the cylinder can drive the lifting rod 531 to slide along the slide rail 535. The lifting rod 531 slides along the axis of the aluminum housing 101.

[0109] When the third acquisition module 53 acquires images, the fixing fixture 53 needs to loosen the capacitor 100 so that the side wall of the aluminum housing 101 of the capacitor 100 can be fully exposed.

[0110] When the third acquisition module 53 acquires an image, first the fixing clamp 53 releases the capacitor 100 and the magnet 532 adsorbs the first pin 104 and the second pin 105, then the lifting rod 531 drives the capacitor 100 to move on the axis of the aluminum shell 101 through the magnet 532, and finally the image of the aluminum shell 101 of the capacitor 100 is acquired through the two third cameras 534.

[0112] Alternatively, if Figure 3 and Figure 7 As shown, the first collection box 54 is located on the fourth station 404. The first collection box 54 includes a first shell 541, a first cover plate 542, a second cover plate 543 and a third cover plate 544. The first shell 541 is provided with a first cavity 5411, a second cavity 5412 and a third cavity 5413. The first cover plate 542 is covered on the first cavity 5411, the second cover plate 543 is covered on the second cavity 5412, and the third cover plate 544 is covered on the third cavity 5413. The first cavity 5411 is used to collect the capacitor 100 with leakage, the second cavity 5412 is used to collect the deformed capacitor 100, and the third cavity 5413 is used to collect the capacitor 100 with the plug not being properly engaged. Such a configuration can facilitate the recovery and reprocessing of unqualified capacitors 100.

[0113] Among them, the first cover plate 542, the second cover plate 543 and the third cover plate 544 are all configured with a driving structure, the driving mechanism of the first cover plate 542 is communicated with the control module 60, the driving structure of the second cover plate 543 is communicated with the control module 60, and the driving structure of the third cover plate 544 is communicated with the control module 60.

[0115] When the control module 60 determines that the capacitor 100 is unqualified based on the image captured by the first acquisition module 51, the control module 60 controls the driving mechanism of the first cover plate 542 to open the first cover plate 542. When the fixed clamp 43 stays at the fourth station 404, the control module 60 controls the fixed clamp 43 to release, and the unqualified capacitor 100 will enter the first cavity 5411.

[0117] When the control module 60 determines that the capacitor 100 is unqualified based on the image captured by the third acquisition module 53, the control module 60 controls the driving mechanism of the third cover 544 to open the third cover 544. When the fixed clamp 43 stays at the fourth station 404, the control module 60 controls the fixed clamp 43 to release, and the unqualified capacitor 100 will enter the third cavity 5413.

[0122] Fig. 9 for Figure 2 The structural diagram of the spiral hopper in FIG. Fig.10 for Figure 2 The structural diagram of the linear hopper in FIG. Fig.11 for Fig.10 The schematic diagram of the structure of the linear hopper and capacitor; Fig.12 for Fig.10 Schematic diagram of the structure of the linear hopper, capacitor, third sensor and fourth sensor.

[0123] Optionally, the first loading module can adjust the postures of multiple capacitors 100 and sequentially enter the working area. The capacitors 100 on the first loading module are capacitors to be detected.

[0124] Among them, Figure 2 and Figure 3 As shown, the first feeding module includes a spiral hopper 11, a linear hopper 12, a first pulse electromagnet 13, a second pulse magnet 14, a third sensor 15 and a fourth sensor 16. The first pulse electromagnet 13 is installed below the spiral hopper 11, the second pulse magnet 14 is installed below the linear hopper 12, the linear hopper 12 is connected to the outlet of the spiral hopper 11, and the third sensor 15 and the fourth sensor 16 are installed on the linear hopper 12.

[0125] The first pulse electromagnet 13 is in communication connection with the control module 60 , and the first pulse electromagnet 13 can make the spiral hopper 11 vibrate when working.

[0126] like Fig. 9 As shown, a spiral track 111 and a spring sheet 112 are provided on the spiral hopper 11. The spring sheet 112 is tiltedly arranged on the spiral track 111. The capacitor 100 in the spiral hopper 11 moves along the spiral track 111 under the vibration of the first pulse electromagnet 13. The spring sheet 112 is used to adjust the posture of the capacitor.

[0127] It should be noted that the capacitor 100 is in a vertical state when it reaches the outlet of the spiral hopper 11 through the spiral track 111. During the movement of the capacitor 100, the spring sheet 112 can make the aluminum shell 101 of the capacitor 100 face the outside of the spiral hopper 11, and the first pin 104 and the second pin 105 of the capacitor 100 face the inside of the spiral hopper 11, so that when the capacitor 100 reaches the outlet of the spiral hopper 11, the first pin 104 and the second pin 105 of the capacitor 100 face downward, and the aluminum shell 101 faces upward.

[0128] The second pulse magnet 14 is in communication connection with the control module 60. When the second pulse magnet 14 is working, the linear hopper 12 is vibrated, and the first pin 104 and the second pin 105 of the capacitor 100 in the linear hopper 12 are facing downward, and the capacitor 100 in the linear hopper 12 moves along the linear track to the working area under the vibration of the second pulse magnet 14. The working area is an area that can store a certain number of capacitors 100.

[0129] In an optional embodiment, if Fig.10As shown, the linear hopper 12 includes a first baffle 121, a second baffle 122 and a bottom plate 123. The first baffle 121 and the second baffle 122 are detachably mounted on the bottom plate 123. The distance between the first baffle 121 and the second baffle 122 is adjustable. The bottom plate 123 has a through slot 1231 through which the first pin 104 and the second pin 105 of the capacitor 100 pass. By adjusting the distance between the first baffle 121 and the second baffle 122, the linear hopper 12 can adapt to capacitors of aluminum housings 101 of different sizes, thereby improving the versatility of the automated equipment for capacitor appearance detection.

[0130] The first baffle 121 , the second baffle 122 , and the bottom plate 123 form a linear track. The first baffle 121 and the second baffle 122 can ensure that the capacitor 100 does not collapse during the movement in the linear track.

[0131] like Fig.11 As shown, the aluminum housing 101 of the capacitor 100 in the linear hopper 12 is partially exposed outside the linear track.

[0132] The third sensor 15 is connected to the control module 60 for communication. The third sensor 15 is used to detect whether there is a capacitor 100 at one end of the working area close to the spring clamp 21. The fourth sensor 16 is used to detect whether there is a capacitor 100 at one end of the working area away from the spring clamp. Fig.12 As shown, when the third sensor 15 detects the presence of capacitor 100, it means that the capacitor has reached the position where the spring clamp 21 can clamp it; when the fourth sensor 16 detects the presence of capacitor 100, it means that the number of capacitors 100 is sufficient, and when the fourth sensor 16 does not detect the presence of capacitor 100, it means that the number of capacitors 100 is insufficient and the spiral hopper 11 needs to supplement capacitor 100.

The first sensor 25 is used to detect whether the corrected first pin 104 is qualified. The second sensor 26 is used to detect whether the corrected second pin 105 is qualified. The rotating fixture 24 is used to clamp the qualified first pin and second pin capacitor 100 and rotate the capacitor 100 180°.

[0136] The spring clamp 21 is provided with a first horizontal moving mechanism, which is a mechanism that can drive the spring clamp 21 to move in the extension direction of the linear track, and stop at the positions of the first correction component, the second correction component, the first sensor 25, the second sensor 26 and the rotating clamp 24 in sequence. The dwell time of the spring clamp 21 can be set according to actual needs. The spring clamp 21 can include two clamps, a spring and a cylinder, the spring is arranged between the clamps, the cylinder rod of the cylinder is fixedly connected to a clamp, and the release and clamping of the two clamps are controlled by the cylinder and the spring.

[0137] like Fig.14 As shown, the first correction component includes a first correction block 221, and the first correction block 221 is provided with a triangular protrusion 2211, which can correct the capacitor with the first pin 104 and the second pin 105 in an inner-eight shape. The first correction block 221 is configured with a first vertical driving mechanism and a second horizontal moving mechanism, the first vertical driving mechanism is a mechanism that can drive the first correction block 221 to move in the vertical direction, and the second horizontal moving mechanism is a mechanism that can drive the first correction block 221 to move in the horizontal direction.

[0138] In an optional embodiment, if Fig.13 and Fig.14 As shown, when the first pin 104 and the second pin 105 of the capacitor 100 are in an inner-eight shape, the triangular protrusion 2211 of the first correction block 221 is first inserted between the first pin 104 and the second pin 105 through the second horizontal moving mechanism, and is set close to the aluminum shell 101, and then the first vertical driving mechanism drives the first correction block 221 to move in the vertical direction. The triangular protrusion 2211 can make the spacing between the first pin 104 and the second pin 105 consistent in the length direction of the first pin 104 and the second pin 105.

[0139] like Fig.13 , Fig.15 and Fig.16As shown, the second correction component includes a second correction block 231, a third correction block 232 and a fourth correction block 233. The second correction block 231 is configured with a third horizontal moving mechanism, and the third correction block 232 is configured with a fourth horizontal moving mechanism. The third horizontal moving mechanism and the fourth horizontal moving mechanism are mechanisms that can make the second correction block 231 and the third correction block 232 abut against each other or move away from each other. The fourth correction block 233 is configured with a second vertical moving mechanism, and the second vertical moving mechanism is a mechanism that can make the fourth correction block 233 move in the vertical direction. The second correction block 231, the third correction block 232 and the fourth correction block 233 can correct the capacitor whose first pin 104 and the second pin 105 are in an outward-facing eight shape.

[0140] like Fig.15 As shown, the second correction block 231 and the third correction block 232 are combined to form a circular hole 2301 and a first inclined surface 2302. Fig.16 As shown, the fourth correction block 233 is provided with a second inclined surface 2303 .

[0141] In an optional embodiment, when the first pin 104 and the second pin 105 of the capacitor 100 are in an outward-facing O-shape, the second correction block 231 and the third correction block 232 are first brought into contact with each other through the third horizontal moving mechanism and the fourth horizontal moving mechanism, the aluminum shell 101 of the capacitor 100 is located in the circular hole 2301, and the first pin 104 and the second pin 105 are located below the aluminum shell 101, and then the fourth correction block 233 is moved along the first inclined surface 2302 through the second vertical moving mechanism. During the movement of the fourth correction block 233 along the first inclined surface 2302, the second inclined surface 2303 clamps the first pin 104 and the second pin 105, thereby correcting the first pin 104 and the second pin 105.

[0142] The rotating clamp 24 can clamp the capacitor 100 from the spring clamp 21 and rotate the capacitor 100 by 180°. After the capacitor 100 is rotated, the aluminum housing 101 faces downward, and the first pin 104 and the second pin 105 face upward.

[0143] The first sensor 25 can detect the bottom end of the first pin 104 . At this time, the first pin 104 is a qualified first pin 104 .

[0144] The second sensor 26 can detect the bottom end of the second pin 105 . At this time, the second pin 105 is a qualified second pin 105 .

[0145] It should be noted that when the first pin 104 or the second pin 105 is unqualified, the control module controls the spring clamp 21 to release, so that the capacitor 100 falls into the box below.
