Description

Technical Field

[0001] This invention belongs to the field of capacitor testing technology, specifically a capacitor testing device. Background Technology

[0002] A capacitor is a component used in electronic circuits to store and release electrical charge. During the capacitor manufacturing process, surface defects often occur, such as broken bushings, blistering, and scratches. To prevent substandard capacitors from entering the market, surface inspection of the capacitors is necessary.

[0003] Patent CN109444159B discloses an appearance inspection device for cylindrical capacitors, including a support, a feeding support, and an appearance inspection device. The appearance inspection device includes a rotating support base, a movable support base, a side camera, an upper camera, and a lower camera. The rotating support base includes a cylindrical rotating lower support base that mates with a lower rotating groove. A pair of symmetrically arranged support plates slide back and forth on the upper end of the rotating lower support base. The movable support base is positioned to the right of the feeding support base, moving left and right. A suction nozzle is mounted on the left end face of the movable support base. The side camera is mounted on a left vertical plate. The lower camera is mounted on the upper end face of the support base and located to the right of the feeding support base. The upper camera is mounted on the horizontal part of the right support plate and located directly above the lower camera. This patent's upper, lower, and side cameras respectively inspect the upper, lower, and side surfaces of the film capacitor, providing comprehensive and efficient inspection.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0047] Specifically, in existing technologies, when inspecting multiple capacitors, the capacitors are sequentially transported to a camera, which then captures images of the capacitor surfaces and uploads the images to an image processing system, thereby enabling the detection of surface defects in the capacitors.

[0048] However, when multiple capacitors are transported, they can easily overlap and obscure each other, preventing the camera from capturing a complete image of the surface of each capacitor and thus affecting the normal detection of the capacitors.

[0049] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0050] This method is applied to the inspection of cylindrical capacitors of the same specifications in the same batch, where the length of the capacitor is greater than its diameter. First, cylinder six (32) drives the adjusting plate 8 to move laterally, so that the distance between one surface of the adjusting plate 8 and one surface of the fixed plate 4 is equal to the capacitor diameter. Furthermore, since one edge of the top of the loading frame 2 is aligned with one edge of the fixed plate 4, the distance between the adjusting plate 8 and the top edge of the loading frame 2 is also equal to the capacitor diameter. Then, cylinder seven (34) drives the guide plate 39 and the telescopic plate 40 to rise and fall, so that the distance between their bottoms and the surface of the conveyor belt 36 is equal to the capacitor diameter. Additionally, cylinder eight (38) drives the telescopic plate 40 to slide inside the guide plate 39, so that the end of the telescopic plate 40 is in contact with the adjusting plate 8.

[0051] The upper surfaces of push plate 1 (26) and push plate 2 (29) together form a rectangular placement surface. The width of the placement surface can be adjusted by having push plate 1 (26) slide on push plate 2 (29) via cylinder 5 (30), making the width equal to the capacitor diameter. Multiple capacitors are then placed on placement plate 3. Initially, the upper surface of placement plate 3 is aligned with the upper surface of push plate 1 (26), causing the capacitors to slide onto the placement surface under gravity. The capacitors' posture on the placement surface is random. Subsequently, motor 4 (28) drives threaded rod 3 (27) to rotate, causing push plate 2 (29) and push plate 1 (26) to move upwards synchronously. Since the width of the placement surface is equal to the capacitor diameter, the capacitor can only be stably placed on the placement surface when its end face is in contact with the surface or when its length direction is parallel to the length direction of the placement surface. Otherwise, the capacitor will fall off due to imbalance. Therefore, only capacitors whose length direction is parallel to the length direction of the placement surface or those that are upright can rise stably. When the placement surface aligns with the upper edge of the loading frame 2, the capacitor will slide onto the conveyor belt 36 and arrange itself on the conveyor belt 36. Then, it will move under the action of the conveyor belt 36. Due to the limiting effect of the adjusting plate 8, the capacitors will not be arranged side by side on the conveyor belt 36. When the capacitor moves to the bottom of the guide plate 39 and the telescopic plate 40, since the distance between the bottom of both and the surface of the conveyor belt 36 is equal to the diameter of the capacitor, only the flat capacitors can pass under the guide plate 39 and the telescopic plate 40. The upright or overlapping capacitors will slide along the guide plate 39 and the telescopic plate 40 to the opening on the fixed plate 4, and then fall back onto the placement plate 3 via the return plate 7. Therefore, the capacitors passing under the guide plate 39 and the telescopic plate 40 are all in a flat state. When a capacitor passes under the infrared sensor 41, the infrared sensor 41 will detect a signal. Then, cylinder 23 drives the blocking block 35 to move, and the blocking block 35 blocks the subsequent capacitor. The capacitor passing through the infrared sensor 41 will slide onto the flipping block 43. Then, cylinder 48 drives the lifting plate 49 to descend, so that the pressure roller 53 is tightly attached to the upper side of the capacitor under the action of the sliding column 50 and the spring 51.Subsequently, cylinder 45 drives connecting plate 47 to rise, causing friction roller 46 to contact the bottom of capacitor. Then, motor 44 drives friction roller 46 to rotate, thus rotating capacitor through friction. At this time, industrial camera 42 can photograph capacitor. As capacitor rotates, industrial camera 42 can capture images of various positions on capacitor surface and upload the captured images to image processing system for analysis, thereby detecting whether there are defects on capacitor surface. When a capacitor is inspected, pressure roller 53 moves away from capacitor. At the same time, motor 9 drives flip block 43 to rotate, causing capacitor to slide down the surface of flip block 43. Then blocking block 35 resets, and subsequent capacitors continue to move onto flip block 43. This process is repeated, enabling continuous inspection of multiple capacitors. During the inspection process, multiple capacitors to be inspected will move onto flip block 43 in an orderly manner before being photographed by industrial camera 42. This prevents capacitors from overlapping and making it difficult to capture complete surface images of each capacitor, thus ensuring the stable operation of the inspection work.

[0052] In this embodiment, as Figures 3-5 As shown, it also includes collection auxiliary components;

[0053] The collection auxiliary components include a bracket 6 slidably connected to one side of the upper surface of the base 1. Both ends of the upper side of the bracket 6 are fixedly connected to a fixing ring 15. Multiple adjusting rods 19 are evenly distributed and slidably connected along the circumference of the fixing ring 15. One end of the adjusting rod 19 is fixedly connected to a limit plate 13. Both ends of one side of the limit plate 13 are fixedly connected to a sliding rod 18. The sliding rod 18 is slidably connected to a slider 55. One side of the slider 55 is fixedly connected to a cylinder 22. The piston end of the cylinder 22 is fixedly connected to a blocking block 37. One side of the limit plate 13 is provided with a through hole for the blocking block 37 to pass through. A baffle 12 is rotatably provided on the lower side of the limit plate 13.

[0054] A motor 21 is fixedly connected to one side of the lower end of the limiting plate 13. The output end of the motor 21 is fixedly connected to one end of the baffle 12. A threaded rod 10 is threadedly connected to one side of the lower end of the bracket 6. Both ends of the threaded rod 10 are rotatably mounted on the base 1. A motor 21 is fixedly connected to one side of the upper end of the base 1. The output end of the motor 21 is fixedly connected to one end of the threaded rod 10.

[0055] A cylinder 14 is fixedly connected to one side of the upper end of the bracket 6. The piston end of the cylinder 14 is fixedly connected to one end of the adjusting rod 19 on both sides. The outer ring of the fixing ring 15 is rotatably fitted with a transmission ring 16. One end of the adjusting rod 19 is rotatably connected with a connecting rod 20, and one end of the connecting rod 20 is rotatably mounted on the transmission ring 16.

[0056] A threaded rod 17 is threadedly connected to one side of the slider 55. Both ends of the threaded rod 17 are rotatably mounted on the limiting plate 13. A motor 54 is fixedly connected to one end of the limiting plate 13. The output end of the motor 54 is fixedly connected to one end of the threaded rod 17.

[0057] Specifically, in the above embodiments, although continuous testing of capacitors can be achieved, and qualified and unqualified products can be collected separately using collection boxes for subsequent processing, when it is necessary to pack a specified number of capacitors into specific collection boxes for storage and transportation based on the quantity of qualified and unqualified capacitors, manual operation and counting by operators are still required. This is not only cumbersome but also prone to confusion and errors.

[0058] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0059] Based on the capacitor's diameter, the piston ends on both sides of cylinder 14 are moved simultaneously, causing the adjusting rods 19 on both sides to slide on the fixed ring 15. With the coordinated action of connecting rod 20 and transmission ring 16, multiple adjusting rods 19 slide radially on the fixed ring 15 simultaneously, causing multiple limiting plates 13 to form a barrier matching the capacitor's diameter. The two barriers are used to receive qualified and unqualified capacitors respectively. Motor 11 drives threaded rod 10 to rotate, causing bracket 6 to slide on base 1. This allows either barrier to align with the flipping block 43, and the tested capacitor will fall into the barrier. Since the barrier size matches the capacitor size, multiple capacitors will be stacked longitudinally within the barrier, and baffle 12 blocks the capacitors, preventing them from falling out.

[0060] Once all capacitors are placed within the enclosure, the collection box can be aligned with the bottom of the enclosure. Based on the required number of capacitors to be removed, motor 6 (54) drives threaded rod 17 to rotate, adjusting the height of slider 55 so that blocking block 37 aligns with the corresponding capacitor. Then, cylinder 22 drives blocking block 37 through the through hole, holding the capacitor in place. Subsequently, motor 3 (21) drives baffle 12 to rotate, causing only the capacitors located below blocking block 37 to fall out. This achieves the collection of a specific number of capacitors, allowing them to be packaged into a designated collection box. This facilitates subsequent capacitor storage and transportation, avoiding confusion and errors caused by manual operation and counting.

[0061] Working principle: First, cylinder 6 (32) drives the adjusting plate 8 to move laterally, so that the distance between one surface of the adjusting plate 8 and one surface of the fixed plate 4 is equal to the diameter of the capacitor. Furthermore, since one edge of the top of the feeding frame 2 is aligned with one edge of the fixed plate 4, the distance between the adjusting plate 8 and the top edge of the feeding frame 2 is also equal to the diameter of the capacitor. Then, cylinder 7 (34) drives the guide plate 39 and the telescopic plate 40 to rise and fall, so that the distance between their bottoms and the surface of the conveyor belt 36 is equal to the diameter of the capacitor. Additionally, cylinder 8 (38) drives the telescopic plate 40 to slide inside the guide plate 39, so that the end of the telescopic plate 40 is in contact with the adjusting plate 8.

[0062] The upper surfaces of push plate 1 (26) and push plate 2 (29) together form a rectangular placement surface. The width of the placement surface can be adjusted by having push plate 1 (26) slide on push plate 2 (29) via cylinder 5 (30), making the width equal to the capacitor diameter. Multiple capacitors are then placed on placement plate 3. Initially, the upper surface of placement plate 3 is aligned with the upper surface of push plate 1 (26), causing the capacitors to slide onto the placement surface under gravity. The capacitors' posture on the placement surface is random. Subsequently, motor 4 (28) drives threaded rod 3 (27) to rotate, causing push plate 2 (29) and push plate 1 (26) to move upwards synchronously. Since the width of the placement surface is equal to the capacitor diameter, the capacitor can only be stably placed on the placement surface when its end face is in contact with the surface or when its length direction is parallel to the length direction of the placement surface. Otherwise, the capacitor will fall off due to imbalance. Therefore, only capacitors whose length direction is parallel to the length direction of the placement surface or those that are upright can rise stably. When the placement surface aligns with the upper edge of the loading frame 2, the capacitor will slide onto the conveyor belt 36 and arrange itself on the conveyor belt 36. Then, it will move under the action of the conveyor belt 36. Due to the limiting effect of the adjusting plate 8, the capacitors will not be arranged side by side on the conveyor belt 36. When the capacitor moves to the bottom of the guide plate 39 and the telescopic plate 40, since the distance between the bottom of both and the surface of the conveyor belt 36 is equal to the diameter of the capacitor, only the flat capacitors can pass under the guide plate 39 and the telescopic plate 40. The upright or overlapping capacitors will slide along the guide plate 39 and the telescopic plate 40 to the opening on the fixed plate 4, and then fall back onto the placement plate 3 via the return plate 7. Therefore, the capacitors passing under the guide plate 39 and the telescopic plate 40 are all in a flat state. When a capacitor passes under the infrared sensor 41, the infrared sensor 41 will detect a signal. Then, cylinder 23 drives the blocking block 35 to move, and the blocking block 35 blocks the subsequent capacitor. The capacitor passing through the infrared sensor 41 will slide onto the flipping block 43. Then, cylinder 48 drives the lifting plate 49 to descend, so that the pressure roller 53 is tightly attached to the upper side of the capacitor under the action of the sliding column 50 and the spring 51. Subsequently, cylinder 45 drives connecting plate 47 to rise, causing friction roller 46 to contact the bottom of capacitor. Then, motor 44 drives friction roller 46 to rotate, thus rotating capacitor through friction. At this time, industrial camera 42 can capture images of capacitor. As capacitor rotates, industrial camera 42 can capture images of various positions on capacitor surface and upload the captured images to image processing system for analysis, thereby detecting whether there are defects on capacitor surface. When a capacitor has completed inspection, pressure roller 53 moves away from capacitor. At the same time, motor 9 drives flip block 43 to rotate, causing capacitor to slide down the surface of flip block 43. Then, blocking block 35 resets, and subsequent capacitors continue to move onto flip block 43. This process is repeated to achieve continuous inspection of multiple capacitors.

[0063] Based on the capacitor's diameter, the piston ends on both sides of cylinder 14 are moved simultaneously, causing the adjusting rods 19 on both sides to slide on the fixed ring 15. With the coordinated action of connecting rod 20 and transmission ring 16, multiple adjusting rods 19 slide radially on the fixed ring 15 simultaneously, causing multiple limiting plates 13 to form a barrier matching the capacitor's diameter. The two barriers are used to receive qualified and unqualified capacitors respectively. Motor 11 drives threaded rod 10 to rotate, causing bracket 6 to slide on base 1. This allows either barrier to align with the flipping block 43, and the tested capacitor will fall into the barrier. Since the barrier size matches the capacitor size, multiple capacitors will be stacked longitudinally within the barrier, and baffle 12 blocks the capacitors, preventing them from falling out. Once all capacitors are placed within the enclosure, the collection box can be aligned with the bottom of the enclosure. Based on the required number of capacitors to be removed, motor 6 54 drives threaded rod 17 to rotate, adjusting the height of slider 55 so that blocking block 37 aligns with the corresponding capacitor. Then, cylinder 22 drives blocking block 37 through the through hole, holding the capacitor in place. Subsequently, motor 3 21 drives baffle 12 to rotate, causing only capacitors located below blocking block 37 to fall out, thus achieving the collection of a specific number of capacitors.
