Capacitor formation device and capacitor formation method

Abstract

The invention discloses a capacitor formation device. The device comprises a formation tank and a carrier for placing a capacitor. The formation device further comprises a pressing device. During formation, the pressing device presses the capacitor above the carrier and is electrically connected with the capacitor. The invention also discloses a capacitor formation method. According to the capacitor formation device and method provided by the embodiments of the invention, during product formation, the pressing device is used for pressing a capacitor product and electrifying the capacitor product, so on one hand, ripple oscillation and buoyancy generated by liquid circulation can be counteracted, and on the other hand, continuous electrification of the product can be ensured, and formationquality and product quality are improved.

Description

technical field [0001] The present invention relates to the technical field of capacitors, and more particularly, to a formation device and a formation method of capacitors. Background technique [0002] When the capacitor is manufactured, it is generally wound to form a prime, and then the positive lead pin of the prime needs to be welded to the iron bar and immersed in the chemical solution for chemical repair. In the prior art, when the capacitor is formed, the capacitor is suspended and then immersed in the forming solution. The positive pole of the capacitor element is in contact with the suspension, the suspension is connected to the positive pole of the power supply, and the negative pole of the power supply is formed into the solution. A fastening bolt is connected with the negative pole of the power supply. After the power is turned on, the chemical conversion repair process is performed, and the chemical conversion time is preset during the chemical conversion pro...

Problems solved by technology

[0003] Because the forming liquid is generally sent in from the bottom of the forming tank with a water pump, the liquid entering the forming tank will cause ripples and vibrations in the liquid in the entire forming tank, and at the same time, the buoyancy of the liquid will cause the capacitor element to sway and sway, so that it will break when the forming is repaired. Continue to power on, and the actual time of formation cannot reach the set value

Because the formation time is preset according to the characteristics of the product material, once the formation time is up, the product will be removed immediately, so it is easy to cause poor formation effect of the capacitor, and the leakage current of the capacitor product is too large to be scrapped, because the actual performance test of the product cannot be completed until the finished product Judgment, even if it is judged that the sorted defective products cannot be reformed like liquid capacitors due to manufacturing process factors
