Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capacitor production equipment, in particular to a capacitor pin detection device. Background Art
[0002] The inside of an electrolytic capacitor contains an electrolyte material that stores charge, which is divided into positive and negative polarity. The positive electrode is a metal substrate with an oxide film attached, and the negative electrode is connected to the electrolyte solid and non-solid through a metal plate. The positive pin of the capacitor is connected to the positive polarity material, and the negative pin is connected to the negative polarity. They cannot be connected in reverse. During the production process of the capacitor, pin detection is an important quality inspection checkpoint. The long pin is connected to the positive pole of the capacitor, and the short pin is connected to the negative pole of the capacitor. In the continuous production process, the directions of the long pin and the short pin of the capacitor cannot be opposite, and the distance between the long pin and the short pin must also be consistent. In addition, a layer of heat-shrinkable PET sleeve with a mark is placed on the capacitor shell. The negative pole mark corresponds to the negative pole pin of the product. The negative pole mark of the sleeve is white and can be detected by optical fiber. When the product passes the optical fiber detection position, the optical fiber reflection amount in the negative pole mark area of the sleeve is large, and the reflection amount in other areas is small. It can be detected whether the negative pole mark area is consistent, thereby realizing the detection of the negative pole line of the capacitor sleeve. The existing technology does not have a device that can simultaneously detect the capacitor pin position, pin spacing and the negative pole line of the capacitor sleeve, so it needs to be improved. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the present invention proposes a capacitor pin detection device, which can simultaneously detect the capacitor pin position, pin spacing and the negative line of the capacitor sleeve.
[0004] The utility model provides a capacitor pin detection device, comprising: a base plate, a push plate mounting seat is installed on the base plate, a push plate arranged facing the paper tape is installed on the push plate mounting seat, a pin spacing detection piece is installed at the front end of the push plate, a first proximity switch arranged facing the push plate is installed at the bottom of the base plate at the rear end of the push plate, a pin detection optical fiber mounting bracket is installed at the right end of the push plate mounting seat, the pin detection optical fiber is installed on the pin detection optical fiber mounting bracket and is arranged facing the paper tape, a foot cutting knife mounting bracket is installed on the left side of the base plate, the foot cutting knife is installed on the foot cutting knife mounting bracket and is arranged facing the paper tape, an electric magnet is installed behind the foot cutting knife, a second proximity switch mounting bracket is installed on the right side of the foot cutting knife mounting bracket, a second proximity switch is installed on the second proximity switch mounting bracket and is arranged facing the paper tape, a detection optical fiber mounting bracket is installed opposite the foot cutting knife mounting bracket, the sleeve negative pole line detection optical fiber is installed on the detection optical fiber mounting bracket and is arranged obliquely from top to bottom facing the capacitor that follows the movement of the paper tape.
[0005] In the above technical solution, during actual operation, the capacitor moves gradually from right to left, driven by the paper braid. During this movement, when the capacitor passes through the pin detection fiber, a signal is generated when the long leg of the capacitor passes through the pin detection fiber, while no signal is generated when the short leg passes through the pin detection fiber. Inconsistency between the output signal and the pin orientation indicates an abnormality, thereby enabling detection of correct pin position during capacitor production. When the capacitor passes through the pin spacing detection sheet, if the spacing between the long and short legs of the capacitor exactly matches the spacing set on the pin spacing detection sheet, the capacitor passes through the sheet normally, the push plate does not retreat, and the first proximity switch does not detect an abnormal signal. However, if the spacing between the long and short legs of the capacitor is too large or too small, it cannot match the spacing set on the pin spacing detection sheet, triggering the push plate to retreat and the first proximity switch to detect a signal, indicating an abnormality. When the capacitor passes through the casing negative pole detection fiber, if the fiber reflection is less than a threshold, an abnormality is indicated. The casing negative pole detection fiber can be used to detect whether the negative pole marking area is consistent. When an abnormality occurs, the capacitor is directly cut off from the pin by pulling the cutting knife through the electric magnet. When three consecutive defects occur, the equipment stops and prompts the fault detection to avoid serious material loss.
[0006] Preferably, the push plate is provided with two parallel and spaced elongated holes, and the push plate is fixed to the push plate mounting base after being passed through the elongated holes by a push plate positioning bolt. A front spring traction screw is installed on the push plate positioning bolt located in the front elongated hole of the push plate, and a rear spring traction screw is installed in front of the rear elongated hole of the push plate. A spring is installed between the front spring traction screw and the rear spring traction screw. In actual operation, the push plate is pushed forward under the action of the spring, so that the pin spacing detection plate installed at the front end of the push plate can contact the pins of the capacitor. If the spacing between the long and short legs of the capacitor is exactly equal to the pin spacing set on the pin spacing detection plate, the capacitor passes the pin spacing detection plate normally, the push plate will not retreat, and the first proximity switch will not detect an abnormal signal. If the spacing between the long and short legs of the capacitor is too large or too small, it cannot match the pin spacing set on the pin spacing detection plate, triggering the push plate to retreat, and the first proximity switch will detect a signal, indicating an abnormality. When the abnormal capacitor passes, the spring force causes the push plate to continue to push forward to detect the next capacitor.
[0007] Preferably, the pins of the capacitor are attached to the front side of the paper tape and move from right to left following the paper tape.
[0008] The beneficial effects of a capacitor pin detection device provided by the utility model are as follows: the capacitor pin detection device has a reasonable design and a simple structure, and can simultaneously detect the capacitor pin position, pin spacing, and the negative electrode line of the capacitor casing. In actual operation, the capacitor is gradually moved from right to left under the drive of the paper braid. During the movement, when the capacitor passes through the pin detection optical fiber, a signal is generated when the long leg of the capacitor passes through the pin detection optical fiber, while no signal output is generated when the short leg passes through the pin detection optical fiber. The output signal is inconsistent with the pin direction, indicating an abnormality, thereby detecting whether the pin position is correct during the capacitor production process. When the capacitor passes through the pin spacing detection plate, if the spacing between the long and short legs of the capacitor is exactly equal to the pin spacing set on the pin spacing detection plate, the capacitor passes through the pin spacing detection plate normally, the push plate will not retreat, and the first proximity switch will not detect an abnormal signal. If the spacing between the long and short legs of the capacitor is too large or too small, it cannot match the pin spacing set on the pin spacing detection plate, triggering the push plate to retreat, and the first proximity switch will detect a signal, indicating an abnormality. When the capacitor passes through the negative-pole detection fiber, if the fiber's reflectance falls below the threshold, it indicates an anomaly. Using the negative-pole detection fiber can verify consistency in the negative-pole marking area. If an anomaly is detected, the capacitor is directly severed at the pins using an electric magnet to pull the cutter. If three consecutive failures occur, the equipment stops, prompting a fault detection prompt and preventing serious material loss. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.
[0013] Embodiment: A capacitor pin detection device.
[0014] Reference Figures 1 to 2 As shown, a capacitor pin detection device includes: a base plate 1, a push plate mounting seat 4 is installed on the base plate 1, a push plate 3 arranged opposite to the paper tape 19 is installed on the push plate mounting seat 4, a pin spacing detection piece 7 is installed at the front end of the push plate 3, a first proximity switch 2 arranged opposite to the push plate 3 is installed at the bottom of the base plate 1 at the rear end of the push plate 3, two parallel and spaced long holes 8 are provided on the push plate 3, the push plate 3 is fixed to the push plate mounting seat 4 after passing through the long hole 8 by a push plate positioning bolt 9, this structural design allows the push plate 3 to slide along the long hole 8, a front spring traction screw 11 is installed on the push plate positioning bolt 9 located in the long hole 8 at the front end of the push plate 3, a rear spring traction screw 11 is installed in front of the long hole 8 at the rear end of the push plate 3, and a spring 10 is installed between the front spring traction screw 11 and the rear spring traction screw 11. During actual operation, the push plate 3 is pushed forward by the force of the spring 10, so that the pin spacing detection piece 7 installed at the front end of the push plate 3 can contact the pins of the capacitor 20 moving with the paper tape 19. If the spacing between the long and short legs of the capacitor 20 is exactly equal to the pitch set on the pin spacing detection piece 7, the capacitor 20 passes through the pin spacing detection piece 7 normally, the push plate 3 will not retreat, and the first proximity switch 2 will not detect an abnormal signal; if the spacing between the long and short legs of the capacitor 20 is too large or too small, it cannot match the pitch set on the pin spacing detection piece 7, which will trigger the push plate 3 to retreat, and the first proximity switch 2 will detect a signal, indicating an abnormality. When the abnormal capacitor 20 passes, the elastic force of the spring 10 will cause the push plate 3 to continue to push forward to detect the next capacitor 20.
[0015] A pin detection optical fiber mounting bracket 5 is installed at the right end of the push plate mounting seat 4, and the pin detection optical fiber 6 is installed on the pin detection optical fiber mounting bracket 5 and is arranged opposite the paper tape 19. During actual operation, when the capacitor 20 passes through the pin detection optical fiber 6, a signal is generated when the long leg of the capacitor 20 passes through the pin detection optical fiber 6, and no signal output is generated when the short leg passes through the pin detection optical fiber 6. The inconsistency between the output signal and the pin direction indicates an abnormality, thereby detecting whether the pin position is correct during the capacitor production process.
[0016] A cutting knife mounting bracket 16 is installed on the left side of the base plate 1, and a cutting knife 17 is installed on the cutting knife mounting bracket 16 and is arranged opposite to the paper tape 19. An electric magnet 18 is installed behind the cutting knife 17. During actual operation, if an abnormality occurs, the cutting knife 17 is pulled by the electric magnet 18 to directly cut off the capacitor 20 from the pin, indicating that the capacitor 20 is defective. When three consecutive defects occur, the equipment stops, prompting a fault detection to avoid serious material loss.
[0017] The second proximity switch mounting bracket 12 is mounted to the right of the foot-cutting knife mounting bracket 16. The second proximity switch 13 is mounted on the second proximity switch mounting bracket 12 and is positioned directly opposite the paper braid 19. The detection fiber mounting bracket 14 is mounted opposite the foot-cutting knife mounting bracket 16. The sleeve negative pole detection fiber 15 is mounted on the detection fiber mounting bracket 14 and is positioned diagonally from top to bottom opposite the capacitor 20 that moves with the paper braid 19. During actual operation, the second proximity switch 13 is used to detect the position of the unqualified capacitor 20 to alert the electric magnet 18 to drive the foot-cutting knife 17. When the capacitor 20 passes through the sleeve negative pole detection fiber 15, if the fiber reflection amount is less than the threshold value, it indicates an abnormality. The sleeve negative pole detection fiber 15 can detect whether the negative pole identification area is consistent. In this embodiment, the pins of the capacitor 20 are attached to the front side of the paper braid 19 and move from right to left with the paper braid 19.
[0018] The present capacitor pin detection device has a reasonable design and a simple structure. It can simultaneously detect the capacitor pin position, pin spacing, and capacitor sleeve negative line, and remove unqualified products. In actual operation, the capacitor 20 is driven by the paper braid 19 and gradually moves from right to left. During the movement, when the capacitor 20 passes through the pin detection optical fiber 6, a signal is generated when the long leg of the capacitor 20 passes through the pin detection optical fiber 6, while no signal is generated when the short leg passes through the pin detection optical fiber 6. The output signal is inconsistent with the pin direction, indicating an abnormality, thereby detecting whether the pin position is correct during the capacitor production process. When the capacitor 20 passes through the pin spacing detection plate 7, if the spacing between the long leg and the short leg of the capacitor 20 is exactly equal to the pin spacing set on the pin spacing detection plate 7, the capacitor 20 passes through the pin spacing detection plate 7 normally, the push plate 3 will not retreat, and the first proximity switch 2 will not detect an abnormal signal. If the spacing between the long leg and the short leg of the capacitor 20 is too large or too small, it cannot match the pin spacing set on the pin spacing detection plate 7, triggering the push plate 3 to retreat, and the first proximity switch 2 will detect a signal, indicating an abnormality. When the capacitor 20 passes through the casing negative electrode detection optical fiber 15, if the optical fiber reflection amount is less than the threshold value, it indicates an abnormality. The casing negative electrode detection optical fiber 15 can detect whether the negative electrode identification area is consistent. After the abnormality occurs, the second proximity switch 13 detects the position of the unqualified capacitor 20 to remind the electric magnet 18 to drive the pin cutting knife 17 to work. When the abnormal capacitor 20 passes the pin cutting knife 17, the electric magnet 18 pulls the pin cutting knife 17 to work, directly cutting the capacitor 20 from the pin. When three consecutive defects occur, the equipment stops, prompting the fault detection to avoid serious material loss.

Therefore, any equivalent or modification completed without departing from the spirit disclosed in the present invention shall fall within the scope of protection of the present invention.
