Description

Technical Field

[0001] The present invention relates to the field of electrolytic capacitor pin detection, and specifically to an electrolytic capacitor pin defect detection device. Background Art

[0002] An electrolytic capacitor is a capacitor that uses an electrolyte as the cathode (or anode), has a relatively large capacitance value, and is usually used in circuits that require large-capacity energy storage. It is characterized by a small volume and a large capacity, but relatively poor withstand voltage and frequency characteristics, and is suitable for occasions such as low-frequency filtering and power supply voltage regulation. When producing electrolytic capacitors, they need to be detected, and a detection device is used to detect the electrolytic capacitors to check whether they meet the factory standards.

[0003] The pins of an electrolytic capacitor are its main components, and the quality of the pins is related to whether the electrolytic capacitor can work properly. Therefore, the detection device can detect whether there are defects in the pins of the electrolytic capacitor. When detecting the electrolytic capacitor, it is usually manually detected with a multimeter. The pins of the electrolytic capacitor are inserted into the detection port of the multimeter, and the value on the display screen of the multimeter is observed to determine whether the electrolytic capacitor is qualified.

[0004] However, the existing manual detection has a low work efficiency. Manually pick up the electrolytic capacitors and insert them one by one into the detection port of the multimeter. It is also necessary to adjust the position of the electrolytic capacitor to avoid reversing the positive and negative poles. After the detection, it is also necessary to manually remove it and then detect the next electrolytic capacitor. This detection method has a low work efficiency and is also rather troublesome. Summary of the Invention

[0034] In the above embodiment, please refer to Figure 1 、 Figure 6 and Figure 7 The first gear 34 is fixed to the first rack 13 and the second gear 34 is fixed to the first rack 13. When the first gear 34 rotates, the first gear 34 is driven by the first gear 34 to rotate. When the first gear 34 rotates, the first gear 33 is driven to rotate.

[0035] In the above embodiment, please refer to Figure 5 , multiple groups of limit sleeve assemblies 15 are set on the top of the fixed plate 6, and the end of the limit sleeve assembly 15 is provided with an upper splint 8, multiple groups of pressure blocks 82 are fixed to the bottom of the upper splint 8, and multiple groups of second racks 81 are fixed to one side of the upper splint 8, multiple groups of connecting frames 9 are fixed on the top of the fixed plate 6, and a second rotating rod 92 is set on the top of the connecting frame 9, and the outer wall of the second rotating rod 92 is provided with a second gear 91, and a first rack 79 is fixed on one side of the connecting plate 71. A group of second rotating rods 92 are connected to the input end of the speed change gear box 4 through a transmission assembly. When the second cylinder 7 works, it drives the connecting plate 7 1 moves upward, and when the connecting plate 71 moves upward, it drives the first rack 79 to move upward. When the first rack 79 moves upward, it drives the second gear 91 to rotate. When the second gear 91 rotates, it drives the second rack 81 to move downward. When the second rack 81 moves downward, it drives the clamping plate 8 to move downward. The clamping plate 8 drives the inner rod 152 downward to slide on the inner wall of the outer rod 151. The clamping plate 8 can press the pins of the electrolytic capacitor so that the pins of the electrolytic capacitor fit with the first metal block 73, the second metal block 74, the third metal block 75 and the fourth metal block 76, so that detection can be convenient.

[0036] In the above embodiment, please refer to Figure 5, a resistor 710 is provided at the end of the connecting plate 71, and two groups of fifth metal blocks 77 are fixed at the end of the connecting plate 71. The fifth metal blocks 77 are connected to the pins at both ends of the resistor 710, and the material of the fifth metal blocks 77 is a conductive metal material. And the two groups of fifth metal blocks 77 are on the same horizontal line. By providing the resistor, the electrolytic capacitor to be detected can be discharged, avoiding the problem that there are electric charges inside the electrolytic capacitor during detection, which may lead to inaccurate inspection results. The two groups of fifth metal blocks 77 being on the same horizontal line can better detect the electrolytic capacitor and can contact the positive and negative pins of the electrolytic capacitor.

[0037] In the above embodiment, specifically, please refer to again Figure 1 , Figure 2 and Figure 7 , the transmission assembly includes a first belt 17, a first pulley 16, a second belt 171 and a second pulley 161. The first pulleys 16 are sleeved at the ends of the two groups of first rotating rods 33, and the first belt 17 is sleeved between the two groups of first pulleys 16. The second pulley 161 is sleeved at the input end of the second rotating rod 92 and the speed change gearbox 4, and the second belt 171 is sleeved between the two groups of second pulleys 161. By providing the transmission assembly, when the first rotating rod 33 rotates, it can drive the lever 32 to rotate through the transmission assembly. When the second gear 91 rotates through the transmission assembly, it can drive the speed change gearbox 4 to work.

[0038] In the above embodiment, specifically, please refer to again Figure 2 , Figure 5 and Figure 9 , the limit sleeve assembly 15 includes an outer rod 151 and an inner rod 152. The outer rod 151 is fixed to the top of the fixing plate 6, and the inner rod 152 is sleeved inside the outer rod 151. An avoidance hole 72 is formed inside the connecting plate 71, and the inner wall of the avoidance hole 72 fits with the outer wall of the outer rod 151. By providing the inner rod 152 and the outer rod 151, when the clamping plate 8 moves upward, it can drive the inner rod 152 to slide inside the outer rod 151, thereby limiting the movement direction of the clamping plate 8, so that the clamping plate 8 can only move up and down, thus better clamping the pins of the electrolytic capacitor. The inner diameter of the avoidance hole 72 is larger than that of the outer rod 151, reducing the friction between the connecting plate 7 and the outer rod 151.

[0039] In the above embodiment, specifically, please refer to again Figure 3 , a third mounting bracket 56 is fixed to one side of the equipment frame 1 away from the fixing plate 6, and a first cylinder 57 is fixed to the end of the third mounting bracket 56. By providing the first cylinder 57, it can push the electrolytic capacitor during operation, making the electrolytic capacitor close to the fixed block 31, so as to facilitate the later detection of the pins of the electrolytic capacitor.

[0040] In the above embodiment, specifically, please refer to againFigure 1 and Figure 2 On one side of the second mounting bracket 51, two sets of limiting rods 53 are fixed, and the limiting rods 53 are located on both sides of the guiding rod 52. A sliding hole 59 is formed inside the dial block 54, and the inner wall of the sliding hole 59 fits with the outer wall of the limiting rod 53. By providing the limiting rod 23, the dial block 54 can be limited, so that the dial block 54 can only slide on the outer wall of the limiting rod 23.

[0041] In the above-mentioned embodiment, specifically, please refer to Figure 3 , a material guiding frame 18 is arranged on one side of the equipment frame body 1, and the material guiding frame 18 is inclined. By providing the material guiding frame 18, it is convenient to guide the falling electrolytic capacitors, and avoid the problem that the electrolytic capacitors are directly dropped and damaged.

[0042] Please refer to Figure 6 and Figure 10 , a rotating groove 35 is formed on one side of the fixed block 31, and a groove 36 is formed on the outer wall of the dial rod 32. By providing the rotating groove 35, one side of the dial rod 32 can be in the same plane as one side of the fixed block 31. The setting of the groove 36 can increase the contact area between the dial rod 32 and the pins of the electrolytic capacitor when the dial rod 32 rotates, and avoid the problem that the pins of the electrolytic capacitor are damaged due to the small contact area.

[0043] When the present invention is specifically working: when in use, the electrolytic capacitor to be detected is placed above the roller 11 above the conveyor belt 26, the pins of the electrolytic capacitor are located on both sides of the fixed block 31, and the electrolytic capacitor does not contact the conveyor belt 26. Subsequently, the motor 21 works to drive the driving roller 22 to rotate intermittently. When the driving roller 22 rotates, it drives the sprocket 27 to rotate. When the sprocket 27 rotates, it drives the chain 25 to drive, thereby driving the conveyor belt 26 to rotate. The conveyor belt 26 drives the electrolytic capacitor to move. When the chain 25 drives, it drives the fixed block 31 to move. When the fixed block 31 moves, the first gear 34 on one side of the fixed block 31 contacts the fourth rack 13, and the fourth gear 13 drives the first gear 34 to rotate. When the first gear 34 rotates, it drives the first rotating rod 33 to rotate. When the first rotating rod 33 rotates, it drives the first pulley 16 to rotate. When the first pulley 16 rotates, it drives another first rotating rod 33 to rotate through the belt 17. The first rotating rod 33 rotates to drive the dial rod 32 to rotate. The dial rod 32 approaches the electrolytic capacitor, and the dial rod 32 rotates to contact the pin end of the electrolytic capacitor, thereby driving the electrolytic capacitor to rotate, so that the pins of the electrolytic capacitor are in a horizontal state. Under the action of the roller 11, when the electrolytic capacitor rotates, the friction force can be reduced. When the electrolytic capacitor moves a certain distance, the motor 21 stops rotating. Subsequently, the first air cylinder 57 works to push the electrolytic capacitor, so that the electrolytic capacitor is closer to the fixed block 31, and the first air cylinder 57 resets; Subsequently, the second cylinder 7 operates. When the second cylinder 7 operates, it drives the connecting plate 71 to move upward. When the connecting plate 71 moves upward, it drives the first rack 79 to move upward. When the first rack 79 moves upward, it drives the second gear 91 to rotate. When the second gear 91 rotates, it drives the second rack 81 to move downward. When the second rack 81 moves downward, it drives the clamping plate 8 to move downward. The clamping plate 8 drives the inner rod 152 to slide on the inner wall of the outer rod 151 downward. When the second cylinder 7 stops operating, at this time, the two groups of fifth metal blocks 77 are in contact with the pins of the electrolytic capacitor, and the pressing block 82 at the bottom of the clamping plate 8 is also in contact with the pins of the electrolytic capacitor, thereby pressing the pins tightly. The electrolytic capacitor is discharged through the resistor 710. Subsequently, a new electrolytic capacitor is continued to be placed above the roller 11, and the second cylinder 7 resets. When the second cylinder 7 resets, it drives the connecting plate 71 to reset. At this time, the clamping plate 8 moves upward; The motor 21 continues to drive the conveyor belt 26 to rotate intermittently. When the motor 21 stops again, the electrolytic capacitor after being discharged and processed moves to one side of the third metal block 75 and the fourth metal block 76. The newly placed electrolytic capacitor repeats the previous discharge operation. The second cylinder 7 drives the connecting plate 71 to move upward. When the second cylinder 7 stops operating, the pins of the electrolytic capacitor are in contact with the third metal block 75 and the fourth metal block 76. If the multimeter 10 does not display any parameters, it indicates that the positive electrode of the electrolytic capacitor is in contact with the third metal block 75, and the fourth metal block 76 is not in contact with the negative electrode of the electrolytic capacitor. If the multimeter 10 displays parameters, it indicates that the positive electrode pin of the electrolytic capacitor is in contact with the fourth metal block 76, and the negative electrode pin of the electrolytic capacitor is in contact with the third metal block 75. Observe the value of the multimeter to determine whether there are defects in the pins of the electrolytic capacitor. The newly placed electrolytic capacitor continues to be placed above the roller 11; Subsequently, the second cylinder 7 resets, and the motor 21 continues to drive the conveyor belt 26 to drive. When the motor 21 stops, the electrolytic capacitor reaches one side of the first metal block 73 and the second metal block 74. Subsequently, the second cylinder 7 continues to operate. When the connecting plate 7 moves upward, it drives the second gear 91 to rotate. When the second gear 91 rotates, it drives the first pulley 16 to rotate. When the second cylinder 7 stops operating, the negative electrode pin of the electrolytic capacitor is in contact with the second metal block 74 and the first metal block 73. If the multimeter 10 does not display any parameters, it indicates that the positive electrode pin of the electrolytic capacitor is in contact with the second metal block 74, and the first metal block 73 is not in contact with the negative electrode of the electrolytic capacitor. If the multimeter 10 displays parameters, it indicates that the positive electrode pin of the electrolytic capacitor is in contact with the first metal block 73, and the negative electrode pin of the electrolytic capacitor is in contact with the second metal block 74. Observe the value of the multimeter to determine whether there are defects in the pins of the electrolytic capacitor. The second group of multimeters 10 is set to test the electrolytic capacitors that did not detect results in the previous step. By setting the connected multimeter 10, the detection structure can be made more accurate and avoid errors; Subsequently, the motor 21 continues to rotate, driving the electrolytic capacitor after detection. When the chain 25 drives the fixed block 31 to move, the first gear 34 on one side of the bottom of the fixed block 31 contacts the third rack 12. Under the action of the third rack 12, the first gear 34 is driven to reverse. When the first gear 34 rotates, it drives the first rotating rod 33 to rotate. The first rotating rod 33 drives the first rotating rod 33 at the top to rotate through the first pulley 16 and the belt 17. When the first rotating rod 33 rotates, it drives the lever 32 to reset; When the motor 21 stops again, a new electrolytic capacitor is continuously placed above the roller 11, and the above operation steps are repeated. When the second cylinder 7 pushes the connecting plate 71 to move upward, it drives the first pulley 16 to rotate. When the first pulley 16 rotates, it drives the first pulley 16 at the input end of the variable speed gearbox 4 to rotate through the belt 17. When the first pulley 16 rotates, it drives the variable speed gearbox 4 to work. Driving the variable speed gearbox 4 to work drives the guide rod 52 to rotate. The guide groove 55 on the outer wall of the guide rod 52 cooperates with the protrusion 510, so that the slider 54 can be driven to slide on its outer wall. When the slider 54 slides, it drives the electrolytic capacitor to move, and the electrolytic capacitor falls above the material guide frame 18. By repeating the above steps, the pins of the electrolytic capacitor can be detected.
