Description

Technical Field

[0001] The utility model relates to the technical field of capacitor aging testing, in particular to an aging sorting machine for aluminum electrolytic capacitors. Background Art

[0002] An aluminum electrolytic capacitor is a capacitor made of an aluminum cylinder as the negative electrode, filled with liquid electrolyte, and a curved aluminum strip inserted as the positive electrode. It is a general-purpose electrolytic capacitor made of aluminum material with good electrical performance, a wide range of applications, and high reliability.

[0003] After the production is completed, the aluminum electrolytic capacitors need to be subjected to aging testing, that is, the aluminum electrolytic capacitors are charged at high temperature and then their performance is tested. The capacitors are then graded according to their performance.

[0004] In the prior art, when performing an aging test on a capacitor, a device is usually installed on the upper end of a fixture, and the capacitor is energized to achieve the purpose of aging the capacitor. However, during the aging process, damaged capacitors may appear, and it is difficult to remove the damaged capacitors in a timely manner when the capacitors are damaged in the prior art, which can easily cause the damaged capacitors to burn and cause irreversible damage to surrounding capacitors and even sorting devices. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an aging sorting machine for aluminum electrolytic capacitors, so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] An aging sorting machine for aluminum electrolytic capacitors includes a collecting trough, a test chassis is provided at the upper end of the collecting trough, a plurality of mounting racks distributed in a rectangular array are provided inside the test chassis, a slidingly connected capacitor clamp is provided at the upper end of the mounting rack, an electromagnetic pop-up mechanism is provided at the bottom end of the mounting rack at a position corresponding to the clamp, and a burying mechanism is provided inside the collecting trough.

[0008] By adopting the above technical solution, the capacitors to be tested are inserted into the capacitor fixture one by one, and then the capacitor fixture is pushed into the interior of the mounting frame. By energizing the capacitor fixture, the capacitors inserted into the capacitor fixture are powered on for testing. When the capacitor is overheated and damaged, the damaged capacitor is ejected by the electromagnetic ejection mechanism, thereby achieving the effect of timely discharge of the damaged capacitor, and the capacitor falls into the interior of the collection tank. The heated capacitor is buried by the burying mechanism, thereby achieving the effect of heat insulation and explosion prevention.

[0009] In a preferred example, the present invention can be further configured as follows: a metal mesh connected to the test chassis is provided between two laterally adjacent mounting frames.

[0010] By adopting the above technical solution and setting the metal mesh, the impact force of the capacitor when it is ejected is reduced, so that the capacitor falls vertically under the influence of gravity after contacting the metal mesh, and falls into the inside of the collection tank, achieving the effect of facilitating collection.

[0011] In a preferred example, the present invention can be further configured as follows: the capacitor clamp includes an extension plate slidably connected to the mounting frame, fixed frames are provided on both sides of the upper end of the extension plate, arc-shaped grooves are provided on opposite sides of the two fixed frames, elastic clamps are embedded in the interior of the arc-shaped grooves, and a pin contact plate slidably connected to the extension plate is provided at a position inside the extension plate between the two opposite arc-shaped grooves.

[0012] By adopting the above technical solution, when installing the capacitor, the end of the capacitor with the pin is directly inserted between the two corresponding elastic clamps, and the elastic clamps are stretched open by the volume processing of the capacitor itself, thereby achieving the effect of fixing the capacitor, and the pin part of the capacitor is brought into contact with the pin contact plate, and then after the extension plate is energized, the current is introduced into the capacitor through the pin contact plate to achieve the testing effect.

[0013] In a preferred example, the present invention can be further configured as follows: the electromagnetic pop-up mechanism includes a mounting groove located inside the mounting frame, an electromagnetic suspension block is provided inside the mounting groove, and the conductive end of the electromagnetic suspension block is connected in series with the pin contact plate at a relative position.

[0014] By adopting the above technical solution, when the capacitor is damaged and heated, the electromagnetic suspension block is pushed upward to hit the pin contact plate, and then the capacitor is pushed out by the impact force generated by the upward movement of the pin contact plate.

[0015] In a preferred example, the present invention can be further configured as follows: a plurality of evenly distributed dry sands are provided inside the collecting tank.

[0016] By adopting the above technical solution, the capacitor is buried with dry sand to isolate the air and prevent the capacitor from continuing to burn.

[0017] In a preferred example, the present invention can be further configured as follows: the burying mechanism includes an air duct located at the bottom end of the collection tank, an exhaust hole is provided at the upper end of the air duct, and one end of the air duct passes through the collection tank and is connected to an air pump.

[0018] By adopting the above technical solution, air is passed into the interior of the collection tank through the air guide pipe and the exhaust hole through the setting of the air guide pump, so as to achieve the effect of rolling the dry sand. When the capacitor falls to the upper end of the dry sand inside the collection tank, it will sink into the interior of the dry sand, thereby achieving the effect of burying the capacitor.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] 1. This aging sorting machine for aluminum electrolytic capacitors uses current fluctuations generated when a capacitor is damaged and overheated, causing the electromagnetic suspension block to vibrate violently. As the electromagnetic suspension block moves upward, it impacts the pin contact plate. The impact force generated by the upward movement of the pin contact plate pushes the capacitor out, thereby timely discharging the damaged and overheated capacitor during the inspection process, thereby protecting the remaining capacitors being tested and the test equipment.

[0021] 2. This aging sorting machine for aluminum electrolytic capacitors has two corresponding elastic clamps, where the elastic clamp close to the metal mesh has a smaller elastic force. Therefore, when the capacitor is ejected, the elastic clamp with a larger elastic force will cause the capacitor to fly toward the metal mesh, thereby preventing the capacitor from falling on the upper end of the capacitor clamp after being ejected. Then, the capacitor falls into the inside of the collection tank under the guidance of the metal mesh, and is buried in the dry sand by the burying device, thereby preventing the capacitor from catching fire.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings. Example

[0029] Reference Figure 1 - Figure 4 The utility model discloses an aging sorting machine for aluminum electrolytic capacitors, which includes a collecting tank 1, a test box 2 is provided at the upper end of the collecting tank 1, a plurality of mounting racks 3 distributed in a rectangular array are provided inside the test box 2, the upper end of the mounting rack 3 is provided with a slidingly connected capacitor clamp 4, the bottom end of the mounting rack 3 is provided with an electromagnetic pop-up mechanism 5 at a position corresponding to the clamp, and a burying mechanism 6 is provided inside the collecting tank 1.

[0030] In this embodiment, the capacitors to be tested are inserted into the capacitor fixture 4 one by one, and then the capacitor fixture 4 is pushed into the mounting frame 3. By energizing the capacitor fixture 4, the capacitors inserted into the capacitor fixture 4 are powered on for testing. When the capacitor is overheated and damaged, the damaged capacitor is ejected by the electromagnetic ejection mechanism 5, thereby achieving the effect of timely discharge of the damaged capacitor, and the capacitor falls into the interior of the collection tank 1. The heated capacitor is buried by the burying mechanism 6, thereby achieving the effect of heat insulation and explosion prevention.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a metal mesh 7 connected to the test chassis 2 is provided between two laterally adjacent mounting frames 3 .

[0032] In this embodiment, when the capacitor is ejected, it contacts the loose metal mesh 7, thereby reducing the impact force of the ejected capacitor, so that the capacitor falls vertically under the influence of gravity after contacting the metal mesh 7, and falls into the interior of the collection tank 1, achieving the effect of facilitating collection.

[0033] In a further preferred embodiment of the present invention, Figure 1-4As shown, the capacitor clamp 4 includes an extension plate 401 that is slidably connected to the mounting frame 3, and fixed frames 402 are provided on both sides of the upper end of the extension plate 401. The two opposite sides of the fixed frames 402 are provided with arc-shaped grooves 403, and elastic clamps 404 are embedded in the arc-shaped grooves 403. A pin contact plate 405 that is slidably connected to the extension plate 401 is provided in the extension plate 401 between the two opposite arc-shaped grooves 403.

[0034] In this embodiment, when installing the capacitor, the end of the capacitor with the pin is directly inserted between the two corresponding elastic clamps 404, and the elastic clamp 404 is stretched out by the volume processing of the capacitor itself, thereby achieving the effect of fixing the capacitor, and the pin part of the capacitor is brought into contact with the pin contact plate 405, and then after the extension plate 401 is energized, the current is introduced into the capacitor through the pin contact plate 405 to achieve the testing effect, and since the elastic clamps 404 at the two corresponding positions have a smaller elastic force, the elastic clamp 404 close to the metal mesh 7 has a smaller elastic force, so when the capacitor is ejected, the elastic clamp 404 with a larger elastic force will cause the capacitor to fly toward the metal mesh 7, so as to achieve the effect of preventing the capacitor from falling on the upper end of the capacitor fixture 4 after being ejected.

[0035] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the electromagnetic pop-up mechanism 5 includes a mounting slot 501 located inside the mounting frame 3, an electromagnetic suspension block 502 is provided inside the mounting slot 501, and the conductive end of the electromagnetic suspension block 502 is connected in series with the pin contact plate 405 at the opposite position.

[0036] In this embodiment, since the capacitor will generate large current fluctuations when it is damaged, and the conductive end of the electromagnetic suspension block 502 is connected in series with the pin contact plate 405, when the capacitor is damaged and generates heat, the electromagnetic suspension block 502 will vibrate violently. When the electromagnetic suspension block 502 moves upward, it will collide with the pin contact plate 405, and the impact force generated by the upward movement of the pin contact plate 405 will have the effect of ejecting the capacitor.

[0037] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a number of evenly distributed dry sands are arranged inside the collecting tank 1.

[0038] In this embodiment, the capacitor is buried in dry sand to isolate the air and prevent the capacitor from continuing to burn.

[0039] In a further preferred embodiment of the present invention, Figure 1-4As shown, the burying mechanism 6 includes an air pipe 601 located at the bottom end of the collection tank 1, an exhaust hole 602 is provided at the upper end of the air pipe 601, and one end of the air pipe 601 passes through the collection tank 1 and is connected to an air pump 603.

[0040] In this embodiment, the air pump 603 is provided to allow air to pass through the air pipe 601 and the exhaust hole 602 into the interior of the collection tank 1, thereby causing the dry sand to tumble. When the capacitor falls to the upper end of the dry sand inside the collection tank 1, it will sink into the dry sand, thereby burying the capacitor.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
