Description

Technical Field

[0001] The present invention relates to the technical field of product leakage electricity, and particularly relates to a device for reducing the leakage current of small shell number products. Background Art

[0002] There has always been a rather thorny problem with aluminum electrolytic capacitor products in small shell numbers, small capacities, and related specifications of 25 - 50V: the leakage current value of the products is large and shows an upward trend. For similar products, the factory leakage current standard is ≤3μA. In the internal aging process and related testing processes, this leakage current value is generally controlled at ≤1.8μA. This value is basically close to the minimum limit of the leakage current control of aluminum electrolytic capacitors, so it is difficult to control. This results in a low aging qualification rate of the products and the leakage current of the products is extremely likely to rise. This phenomenon has seasonal characteristics and has a relatively high probability of occurring from May to October every year.

[0003] In the prior art, the reason for the leakage current of small shell number products is that the aging repair time is insufficient, and the repair of the surface of the product forming pins during aging is not completely carried out. Therefore, how to control the forming effect on the surface of the pins is the key to controlling the leakage current. The pins are also called conductive pins. It is very necessary to cool the conductive pins, which plays a great role in avoiding the leakage current of small shell number products. Therefore, there is an urgent need for a device for reducing the leakage current of small shell number products. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for reducing the leakage current of small shell number products, which solves the problem that in the prior art, the reason for the leakage current of small shell number products is that the aging repair time is insufficient and the repair of the surface of the product forming pins during aging is not completely carried out.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A device for reducing the leakage current of small shell number products includes a box body. A base is fixedly connected to the bottom of the box body, and a refrigerating machine is fixedly connected to one side of the top of the base through bolts. Air outlet covers are fixedly connected to both the upper side and the lower side of the box body, and cold air pipes at the air outlet of the refrigerating machine are respectively communicated between the two air outlet covers. A driving motor is fixedly connected to the top of the box body through bolts. A bearing rod is rotatably connected to the inside of the box body, and a plurality of bearing plates are fixedly connected to the bearing rod along the vertical direction. A plurality of bearing grooves are formed at the bottom of all the bearing plates, and limiting plates are rotatably connected to both sides of the inside of all the bearing grooves through torsion spring shafts. The top end of the bearing rod penetrates through the top of the box body and is in transmission connection with the output shaft of the driving motor.

[0007] Preferably, sliding blocks are fixedly connected to both sides of all the bearing plates, and the sliding blocks are fixedly connected to the inner wall of the box body through annular grooves.

[0008] Preferably, both one side of the bottom and one side of the top of the box body are fixedly connected with bearing frames, and filter plates are arranged inside both bearing frames. Both sides of the filter plate are fixedly connected with sliding blocks, and the sliding blocks are slidably connected with the inner wall of the box body through sliding grooves.

[0009] Preferably, one side of the inner top of the box body is rotatably connected with a connecting rod, and the bottom end of the connecting rod is fixedly connected with a fan. And the top end of the connecting rod passes through the top of the box body through a bearing sleeve. Among them, the connecting rod and the bearing rod are wound and connected through a belt.

[0010] Preferably, pulley wheels are sleeved on one end of the connecting rod located at the top of the box body and one end of the bearing rod located at the top of the box body, and the two pulley wheels are wound and connected through a belt.

[0011] Preferably, the bottom end of the bearing rod is rotatably connected with the inner bottom of the box body through a rotating shaft, and the top end of the bearing rod passes through the top of the box body through a bearing sleeve. One side of the outside of the box body is rotatably connected with a door body through a hinge, and fixing frames are fixedly connected to the tops of all bearing plates.

[0012] The present invention at least has the following beneficial effects:

[0013] When the device for reducing the leakage current of small shell number products in the present invention is used, first place the guide pins to be cooled into the bearing grooves on the bearing plates, that is, press down the two limit plates in the bearing grooves, so that the two limit plates are separated. At this time, the guide pins can be placed into the bearing grooves, and then release the limit plates, so that the two limit plates are butted under the action of the torsion spring rotating shaft to limit the guide pins. Then start the driving motor and the refrigerator, use the refrigerator to transport the cold air into the box body through the cold air pipe and the air outlet cover, and then use the driving motor to drive the bearing plates on the bearing rod to rotate, and then all the guide pins can be driven to rotate, so that the contact between the guide pins and the cold air is more uniform, until the guide pins are cooled to a certain degree. Compared with the prior art, the reason for the leakage current of small shell number products is that the aging repair time is insufficient and the repair of the surface of the product forming guide pins during aging is not completely carried out. The method proposed in the present invention, through the rotation of the bearing plates and the bearing of the guide pins through the bearing grooves, and using the refrigerator to input cold air, can make the guide pins be cooled evenly. After taking out the guide pins after more than 12 hours, without changing the aging process, the leakage current value of the product can be effectively controlled.
