Description

Technical Field

[0001] This utility model relates to capacitor manufacturing technology, and in particular to a capacitor appearance inspection device. Background Technology

[0002] A capacitor is a common electronic component, its basic structure consisting of electrodes, an electrolyte, and an insulating chamber. When a DC voltage is applied across the capacitor, ions in the electrolyte move directionally under the influence of the electric field, causing positive charges to accumulate on the anode plate and negative charges on the cathode plate, thus storing charge. The voltage across the capacitor gradually increases until it equals the applied voltage. When an external circuit is connected, the stored charge is released through the circuit. The charge on the plates gradually decreases, and the voltage drops accordingly. Ions in the electrolyte move in the opposite direction to maintain the flow of charge until the stored electrical energy is completely released. Capacitors are commonly used for filtering, coupling, and storing electrical signals in circuits.

[0003] During the manufacturing process, capacitors are easily damaged due to impacts with equipment or handling by robotic arms. Damaged capacitors are more prone to failure during use, posing serious safety hazards to users. Therefore, manufacturers need to inspect the appearance of capacitors before they leave the factory.

[0004] Currently, capacitor appearance inspection is all done manually, which is labor-intensive and inefficient. Utility Model Content

[0037] Example 1

[0038] like Figure 1 and 2 As shown, a capacitor appearance inspection device includes:

[0039] The turntable mechanism 1 includes a detection turntable 11 and a drive component 12. The drive component 12 drives the detection turntable 11 to rotate. Multiple detection grippers 13 are evenly distributed on the outer periphery of the detection turntable 11. Each detection gripper 13 switches to a different workstation in sequence as the detection turntable 11 rotates.

[0040] The feeding mechanism 2, the unloading mechanism 3, and multiple appearance inspection mechanisms 4 are respectively arranged next to the corresponding workstations of the inspection turntable 11, and the appearance inspection mechanisms 4 are sequentially distributed between the feeding mechanism 2 and the unloading mechanism 3 along the rotation direction of the inspection turntable 11.

[0041] The appearance inspection device of this utility model uses the rotation of the inspection turntable 11 to sequentially switch each inspection gripper 13 to different workstations. When each inspection gripper 13 is switched to a workstation corresponding to the feeding mechanism 2, the feeding mechanism 2 feeds the capacitor onto each inspection gripper 13. When each inspection gripper 13 is sequentially switched to a workstation corresponding to each appearance inspection mechanism 4, each appearance inspection mechanism 4 sequentially performs appearance inspection on the capacitor on each inspection gripper 13. When each inspection gripper 13 is switched to a workstation corresponding to the unloading mechanism 3, the unloading mechanism 3 removes the capacitor from each inspection gripper 13, thereby realizing automated inspection of the appearance of the capacitor and greatly improving inspection efficiency.

[0042] The drive assembly 12 includes a drive motor 121, a transmission unit 122, and a divider 123. The divider 123 has a transverse input shaft 123a and a longitudinal output shaft 123b. The transverse input shaft 123a of the divider 123 is connected to the output shaft 121a of the drive motor 121 via the transmission unit 122. The longitudinal output shaft 123b of the divider 123 is fixedly connected to the center of the detection turntable 11. The transmission unit 122 includes a drive wheel 122a, a driven wheel 122b, and a transmission belt 122c. The drive wheel 122a is coaxially fixed to the output shaft 121a of the drive motor 121, the driven wheel 122b is coaxially fixed to the transverse input shaft 123a of the divider 123, and the transmission belt 122c is sleeved between the drive wheel 122a and the driven wheel 122b.

[0043] The capacitor includes a cell portion and a lead portion. The cell portion is cylindrical or other common shapes. The lead portion is located at the top of the cell portion and includes a positive lead and a negative lead.

[0044] Preferably, each appearance inspection mechanism 4 is used to inspect the appearance at different locations on the capacitor, and includes at least one of the following inspection mechanisms:

[0045] The first testing mechanism 41 is used to test the appearance of the upper and lower end faces of the capacitor;

[0046] The second testing unit 42 is used to test the appearance of the side of the capacitor cell;

[0047] The third testing unit 43 is used to test the appearance of the upper inclined surface of the capacitor;

[0048] The fourth inspection unit 44 is used to inspect the appearance of the lead side of the capacitor;

[0049] The fifth inspection unit 45 is used to inspect the appearance of the lower inclined surface of the capacitor.

[0050] In this embodiment, the first detection mechanism 41, the second detection mechanism 42, the third detection mechanism 43, the fourth detection mechanism 44, and the fifth detection mechanism 45 are sequentially distributed around the detection turntable 11 along its rotation direction. Of course, the positional order of the first detection mechanism 41, the second detection mechanism 42, the third detection mechanism 43, the fourth detection mechanism 44, and the fifth detection mechanism 45 can be adjusted according to specific detection requirements and should not be limited to this embodiment.

[0051] like Figure 3 As shown, the first detection mechanism 41 includes an upper surface detection light source 411, an upper surface detection camera 412, a lower surface detection light source 413, a lower surface detection camera 414, and a first lifting assembly 414. The upper surface detection light source 411 and the upper surface detection camera 412 are located above the detection gripper 13, and the lower surface detection light source 413 and the lower surface detection camera 414 are located below the detection gripper 13. The first lifting assembly 414 drives the upper surface detection light source 411 and the upper surface detection camera 412 to move up and down, so as to adjust the distance between the upper surface detection light source 411 and the upper surface detection camera 412 and the upper surface of the capacitor.

[0052] When performing visual inspection on the upper and lower end faces of the capacitor, the inspection gripper 13 first transports the capacitor to the workstation corresponding to the first inspection mechanism 41 by rotating the inspection turntable 11; the upper end face inspection light source 411 emits light towards the upper end face of the capacitor to illuminate the upper end face of the capacitor, while the upper end face inspection camera 412 takes a picture of the upper end face of the capacitor to obtain an image of the upper end face of the capacitor, thereby performing visual inspection on the upper end face of the capacitor; at the same time, the lower end face inspection light source 413 emits light towards the lower end face of the capacitor to illuminate the lower end face of the capacitor, while the lower end face inspection camera 414 takes a picture of the lower end face of the capacitor to obtain an image of the lower end face of the capacitor, thereby performing visual inspection on the lower end face of the capacitor.

[0053] In this embodiment, the positions of the lower end face detection light source 413 and the lower end face detection camera 414 are fixed, and the distance between them and the lower end face of the capacitor cannot be adjusted. Of course, depending on the specific detection needs, and if the structure allows, the first detection mechanism 41 can also be equipped with another lifting component to connect and drive the lower end face detection light source 413 and the lower end face detection camera 414 to lift. Alternatively, the lower end face detection light source 413 and the lower end face detection camera 414 can also be mounted on the first lifting component 414, thereby adjusting the distance between the lower end face detection light source 413 and the lower end face detection camera 414 and the lower end face of the capacitor.

[0054] The upper surface detection light source 411 and the lower surface detection light source 413 are mainly composed of a housing with a viewing window, a diffuse reflection glass, and an LED light source. The LED light source is located inside the housing, and the diffuse reflection glass is located at the viewing window of the housing. The light emitted by the LED light source is diffused by the diffuse reflection glass and then exits from the viewing window of the housing onto the upper or lower surface of the capacitor. The upper surface detection camera 412 is located above the upper surface detection light source 411, and the lower surface detection camera 414 is located below the lower surface detection light source 413, so that the upper surface detection camera 412 and the lower surface detection camera 414 can respectively capture images of the upper and lower surfaces of the capacitor through the viewing windows of the upper surface detection light source 411 and the lower surface detection light source 413.

[0055] like Figure 4 As shown, the second detection mechanism 42 includes an outer detection light source 421, an outer detection camera 422, a first rotating seat 423, a first rotating component 424, and a second lifting component 425. The first rotating seat 423 is located below the detection gripper 13. The first rotating component 424 drives the first rotating seat 423 to rotate. The second lifting component 425 drives the first rotating seat 423 to lift. The outer detection light source 421 and the outer detection camera 422 are located on the side of the first rotating seat 423 away from the detection gripper 13, and their optical axes are perpendicular to the rotation axis of the first rotating seat 423.

[0056] When performing visual inspection on the side of the capacitor cell, the inspection gripper 13 first transports the capacitor to the workstation corresponding to the second inspection mechanism 42 by rotating the inspection turntable 11. After the second lifting component 425 drives the first rotating seat 423 to rise, the capacitor is released and placed on the first rotating seat 423. The outer inspection light source 421 emits light towards the side of the capacitor cell to illuminate the side of the capacitor cell, while the outer inspection camera 422 takes pictures of the side of the capacitor cell. At the same time, the first rotating component 424 drives the first rotating seat 423 and the capacitor to rotate, so that the outer inspection camera 422 can acquire images of each side of the capacitor cell by taking multiple pictures, thereby performing visual inspection on the side of the capacitor cell.

[0057] The outer detection light source 421 mainly consists of an upper light bar, a lower light bar, and a light bar bracket. The upper and lower light bars are both fixedly mounted on the light bar bracket and are arranged vertically opposite each other. The outer detection camera 422 is located on the side of the outer detection light source 421 away from the first rotating seat 423, so as to take pictures of the side of the capacitor cell portion through the gap between the upper and lower light bars.

[0058] like Figure 5 As shown, the third detection mechanism 43 includes an upward tilt detection light source 431, an upward tilt detection camera 432, a second rotating seat 433, a second rotating component 434, a third lifting component 435, and a fourth lifting component 436. The second rotating seat 433 is located below the detection gripper 13. The second rotating component 434 drives the second rotating seat 433 to rotate. The third lifting component 435 drives the second rotating seat 433 to rise or fall. The upward tilt detection light source 431 and the upward tilt detection camera 432 are located above the detection gripper 13, and their optical axes are tilted relative to the rotation axis of the second rotating seat 433. The fourth lifting component 436 drives the upward tilt detection light source 431 and the upward tilt detection camera 432 to rise or fall, thereby adjusting the distance between the upward tilt of ...

[0059] When performing visual inspection on the upper inclined surface of the capacitor, the inspection gripper 13 first transports the capacitor to the workstation corresponding to the third inspection mechanism 43 by rotating the inspection turntable 11. After the third lifting component 435 drives the second rotating seat 433 to rise, the capacitor is released and placed on the second rotating seat 433. The upper inclined detection light source 431 emits light towards the upper inclined surface of the capacitor to illuminate it, while the upper inclined detection camera 432 takes pictures of the upper inclined surface of the capacitor. At the same time, the second rotating component 434 drives the capacitor to rotate, so that the upper inclined detection camera 432 can acquire images of each upper inclined surface of the capacitor through multiple shots, thereby performing visual inspection on the upper inclined surface of the capacitor.

[0060] It should be noted that the upper tilt surface refers to the upper end surface and the side surface of the capacitor, that is, the upper tilt detection camera 432 needs to capture the upper end surface and the side surface of the capacitor in the same image at the same time.

[0061] The upward tilt detection light source 431 is an annular light source panel. The upward tilt detection camera 432 is disposed on the side of the upward tilt detection light source 431 away from the second rotating component 434 and aligned with the annular center of the upward tilt detection light source 431 so as to capture images of the upward tilt surface of the capacitor through the annular center of the upward tilt detection light source 431.

[0062] like Figure 6 As shown, the fourth detection mechanism 44 includes a pin detection light source 441, a pin detection camera 442, a third rotating seat 443, a third rotating assembly 444, and a fifth lifting assembly 445. The third rotating seat 443 is located below the detection gripper 13. The third rotating assembly 444 drives the third rotating seat 443 to rotate. The fifth lifting assembly 445 drives the third rotating seat 443 to lift. The pin detection light source 441 and the pin detection camera 442 are both located above the detection gripper 13, and their optical axes are perpendicular to the rotation axis of the third rotating seat 443. The pin detection light source 441 is located on one side of the third rotating seat 443, and the pin detection camera 442 is located on the other side of the third rotating seat 443.

[0063] When performing visual inspection on the side of the capacitor's leads, the inspection gripper 13 first transports the capacitor to the workstation corresponding to the fourth inspection mechanism 44 by rotating the inspection turntable 11. After the fifth lifting assembly 445 drives the third rotating seat 443 to rise, the capacitor is released and placed on the third rotating seat 443. The lead detection light source 441 emits light towards the side of the capacitor's lead portion to illuminate the side of the lead portion, while the lead detection camera 442 takes pictures of the side of the capacitor's lead portion. At the same time, the third rotating assembly 444 drives the capacitor to rotate, so that the lead detection camera 442 can acquire images of each side of the capacitor's lead portion through multiple shots, thereby performing visual inspection on the side of the capacitor's leads.

[0064] In this embodiment, the pin detection light source 441 is located on the side of the third rotating seat 443 away from the detection turntable 11; the pin detection camera 442 is located on the side of the third rotating seat 443 close to the detection turntable 11.

[0065] like Figure 7As shown, the fifth detection mechanism 45 includes a tilting detection light source 451, a tilting detection camera 452, a rotating gripper 453, and a fourth rotating component 454. The rotating gripper 453 is positioned above the detection gripper 13, and its gripping direction is perpendicular to the gripping direction of the detection gripper 13. The fourth rotating component 454 drives the rotating gripper 453 to rotate. The tilting detection light source 451 and the tilting detection camera 452 are positioned below the detection gripper 13, and their optical axes are tilted relative to the rotation axis of the rotating gripper 453.

[0066] When performing visual inspection on the lower inclined surface of the capacitor, the inspection gripper 13 first transports the capacitor to the workstation corresponding to the fifth inspection mechanism 45 by rotating the inspection turntable 11. After the rotating gripper 453 grips the capacitor, it releases the capacitor to transfer it to the rotating gripper 453. The lower inclined detection light source 451 emits light towards the lower inclined surface of the capacitor to illuminate it, while the lower inclined detection camera 452 takes pictures of the lower inclined surface of the capacitor. At the same time, the fourth rotating component 454 drives the rotating gripper 453 and the capacitor to rotate, so that the lower inclined detection camera 452 can acquire images of each lower inclined surface of the capacitor through multiple shots, thereby performing visual inspection on the lower inclined surface of the capacitor.

[0067] It should be noted that the lower tilt surface refers to the lower end surface and the side surface of the capacitor, that is, the lower tilt detection camera 452 needs to capture the lower end surface and the side surface of the capacitor in the same image at the same time.

[0068] In this embodiment, the tilting detection light source 451 is located directly below the detection gripper 13, and the pin detection camera 442 is located on the lower side of the detection gripper 13.

[0069] Preferred, such as Figure 1 As shown, the appearance inspection device also includes a protrusion detection mechanism 5, which is used to detect whether the capacitor has a bottom protrusion.

[0070] During the production or transportation of capacitors, bulges often appear on the bottom of the capacitor due to vibration, collision or internal short circuit. The bottom of the capacitor is very small, and it is difficult to detect the bottom bulges by relying solely on visual inspection systems.

[0071] like Figure 8As shown, the protrusion detection mechanism 5 includes a limiting seat 51, a contact sensor 52, and a sixth lifting assembly 53. The sixth lifting assembly 53 connects and drives the limiting seat 51 and the contact sensor 52 to move up and down. The limiting seat 51 is located below the detection gripper 13 and has a limiting hole 511 for accommodating the capacitor. The contact sensor 52 includes a sensing part 521 and a probe part 522. The sensing part 521 is located below the limiting seat 51. One end of the probe part 522 is connected to the sensing part 521, and the other end extends into the limiting hole 511 of the limiting seat 51.

[0072] When detecting the bottom protrusion of the capacitor, the detection gripper 13 first transports the capacitor to the workstation corresponding to the protrusion detection mechanism 5 by rotating the detection turntable 11. The sixth lifting assembly 53 drives the limiting seat 51 and the contact sensor 52 to rise synchronously. During the lifting process, the bottom of the capacitor first enters the limiting hole 511 of the limiting seat 51. As the capacitor continues to rise, the probe part 522 of the contact sensor 52 contacts the bottom of the capacitor, thereby triggering the sensing part 521 to generate a sensing signal. If the capacitor has a bottom protrusion, the rising amount of the probe part 522 is small. If the capacitor does not have a bottom protrusion, the rising amount of the probe part 522 is large. The rising amount of the probe part 522 can be calculated by the triggering time of the sensing part 521, thereby determining whether the capacitor has a bottom protrusion.

[0073] The protrusion detection mechanism 5 can be located between any two appearance inspection mechanisms 4. In this embodiment, the protrusion detection mechanism 5 is located between the first inspection mechanism 41 and the second inspection mechanism 42.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
