Technical Field

[0001] The present invention relates to the technical field of capacitors, and in particular to an assembling device and an assembling method for aluminum electrolytic capacitors. Background Art

[0002] Aluminum electrolytic capacitors are capacitors made of aluminum cylinders as negative electrodes, liquid electrolytes inside, and a curved aluminum strip inserted as positive electrodes. It is a general-purpose electrolytic capacitor made of aluminum material with good electrical properties, wide application range, and high reliability. It is widely used in air conditioners, recorders, and other household appliances as well as electronic machines, instruments, and meters.

[0003] In traditional aluminum electrolytic capacitor assembly equipment, a clamp of fixed size is used to directly clamp the outer wall of the capacitor. The shape of the clamp matches the shape of the capacitor and is fixed to the fixture body by bolts, nuts and other connectors. When clamping the capacitor, tighten the bolts to apply pressure to fix it. In terms of the supporting structure, a flat plate made of metal or plastic plate is usually used, which is directly placed on the workbench of the assembly equipment to provide a basic support surface for the capacitor.

[0004] When products of different specifications need to be assembled, it is often necessary to frequently replace fixtures and adjust support structures, which reduces assembly efficiency. At the same time, when the equipment is running or subjected to external vibrations, the capacitor is prone to displacement or damage, affecting the normal operation and service life of the equipment.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] like Figures 1 to 5 As shown, an aluminum electrolytic capacitor assembly device includes a accommodating tube 1, a clamping mechanism and a supporting mechanism. An aluminum electrolytic capacitor body 2 is installed in the accommodating tube 1. The clamping mechanism is arranged inside the accommodating tube 1 and is used to clamp the outer peripheral wall of the aluminum electrolytic capacitor body 2; the clamping mechanism includes a clamping ring 3, a first spring 31 and a pulling plate 32. The clamping rings 3 are arranged on both sides of the accommodating tube 1, and the first spring 31 is arranged between the outer peripheral wall of the clamping ring 3 and the inner wall of the accommodating tube 1, and the aluminum electrolytic capacitor body 2 is arranged between the clamping rings 3 on both sides; the pulling plate 32 is fixedly arranged on the top of the clamping ring 3 and extends to the outside of the accommodating tube 1, and the outer side wall of the clamping ring 3 is provided with a guide column 33, and the guide column 33 extends to the outside of the accommodating tube 1 and is connected to a limiting ring 34, and the guide column 33 is slidably matched with the accommodating tube 1; the supporting mechanism is arranged at the bottom of the aluminum electrolytic capacitor body 2.

[0028] Pull the pull plate 32, and under the guidance of the guide column 33, the clamping ring 3 is driven to overcome the elastic force of the first spring 31 and move toward the inner wall of the accommodating tube 1. When the aluminum electrolytic capacitor body 2 needs to be installed, the spacing between the two clamping rings 3 is expanded by pulling the limiting ring 34 to provide space for installation. After the installation is completed, loosen the limiting ring 34, and under the elastic force of the first spring 31, the two clamping rings 3 tightly clamp the outer peripheral wall of the aluminum electrolytic capacitor body 2 from both sides to achieve a stable clamping.

[0029] The elastic force of the first spring 31 is used to elastically clamp the aluminum electrolytic capacitor body 2, which can adapt to aluminum electrolytic capacitor bodies 2 of different sizes. The support mechanism provides stable support at the bottom. The two work together to firmly fix the aluminum electrolytic capacitor body 2 in the accommodating tube 1. In the subsequent use process, even if it is subjected to certain external force vibration or impact, it can remain stable and is not prone to displacement or damage, thereby ensuring the normal operation of the capacitor.

[0030] The support mechanism includes a support plate 4 and a second spring 41. The support plate 4 is arranged at the bottom of the aluminum electrolytic capacitor body 2. One end of the second spring 41 is connected to the bottom of the accommodating tube 1, and the other end is connected to the bottom of the support plate 4. Two mounting grooves 42 are provided on the support plate 4. Two mounting blocks 21 are provided at the bottom of the aluminum electrolytic capacitor body 2. The mounting blocks 21 are arranged in the mounting grooves 42.

[0031] One end of the second spring 41 is connected to the bottom of the accommodating tube 1, and the other end is connected to the support plate 4, providing an upward elastic force for the support plate 4. The mounting groove 42 on the support plate 4 cooperates with the mounting block 21 at the bottom of the aluminum electrolytic capacitor body 2 to achieve positioning and preliminary support for the capacitor body. During the installation process, pressing the support plate 4 can compress the second spring 41 to disengage the clamping ring 3, making it easier for the clamping ring 3 to clamp the capacitor body. Provide stable bottom support to ensure the verticality and stability of the aluminum electrolytic capacitor body 2 in the accommodating tube 1; the cooperation between the mounting groove 42 and the mounting block 21 facilitates positioning and installation and improves assembly accuracy.

[0032] The outer wall of the accommodating tube 1 is provided with a plurality of first heat dissipation holes 11, and the outer wall of the clamping ring 3 is provided with a plurality of second heat dissipation holes 35. When the aluminum electrolytic capacitor generates heat during operation, hot air will be discharged through the first heat dissipation holes 11 on the outer wall of the accommodating tube 1 and the second heat dissipation holes 35 on the outer wall of the clamping ring 3, thereby achieving heat dissipation, effectively reducing the operating temperature of the capacitor, preventing performance degradation or damage due to overheating, and extending the service life of the capacitor.

[0033] The side wall of the accommodating tube 1 is provided with a positioning hole, and a positioning screw 5 is provided at the positioning hole. The positioning screw 5 penetrates the accommodating tube 1, and the positioning screw 5 located inside the accommodating tube 1 penetrates the two mounting blocks 21. The second spring 41 is provided on both sides of the positioning screw 5.

[0034] The positioning screw 5 passes through the positioning hole on the side wall of the accommodating tube 1 and the two mounting blocks 21 at the bottom of the aluminum electrolytic capacitor body 2. By tightening the positioning screw 5, the capacitor body is firmly fixed in the accommodating tube 1, further enhancing the fixing effect of the aluminum electrolytic capacitor body 2, preventing it from being displaced during use, and improving the reliability of the equipment. At the same time, the second spring 41 is located on both sides of the positioning screw 5 to avoid interference when the positioning screw 5 is inserted, ensuring that the support plate 4 is evenly stressed, and always remains stable during compression and extension, improving the stability of the support, and avoiding unstable installation or damage to the capacitor body due to the tilt of the support plate 4.

[0035] The size of the mounting block 21 is adapted to the mounting groove 42, thereby ensuring the accuracy and firmness of the installation, reducing installation errors, and improving assembly efficiency and product quality.

[0036] The pull plate 32 and the clamping ring 3 are an integral structure, and a first arc surface 6 is provided at the connection between the pull plate 32 and the clamping ring 3. The pull plate 32 and the clamping ring 3 are integrally formed to ensure the strength and stability of the structure. The first arc surface 6 at the connection between the pull plate 32 and the clamping ring 3 can reduce the friction force when the aluminum electrolytic capacitor body 2 is installed, thereby reducing damage.

[0037] A second arc surface 7 is provided at the bottom of the clamping ring 3. In the initial state, the support plate 4 is arranged in the middle of the clamping rings 3 on both sides. After the aluminum electrolytic capacitor body 2 is installed, the support plate 4 is located below the clamping ring 3, and the top of the support plate 4 is in contact with the second arc surface 7.

[0038] The pull plate 32 is provided with a gripping groove 321 to facilitate the staff to grip and pull the pull plate 32 . Under the action of the guide pillar 33 , the distance between the two clamping rings 3 is expanded to facilitate the installation of the aluminum electrolytic capacitor body 2 .

[0039] The working principle of the present invention is as follows: pull the pull plate 32, and under the guidance of the guide column 33, the clamping ring 3 overcomes the elastic force of the first spring 31 and moves toward the inner wall of the accommodating tube 1, thereby expanding the distance between the two clamping rings 3. Under the elastic force of the second spring 41, the support plate 4 extends between the two clamping rings 3 to abut against them; align the mounting block 21 at the bottom of the aluminum electrolytic capacitor body 2 with the mounting groove 42 on the support plate 4, slowly lower it, so that the mounting block 21 falls into the mounting groove 42, press the support plate 4 downward, compress the second spring 41, and when the support plate 4 is separated from the two clamping plates, the two clamping plates clamp the aluminum electrolytic capacitor body 2 under the elastic force of the first spring 31; pass the positioning screw 5 through the positioning hole on the side wall of the accommodating tube 1, penetrate the two mounting blocks 21, tighten the positioning screw 5, and lock the aluminum electrolytic capacitor body 2.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
