Problems solved by technology

Among them, the metallized film will have coating defects during the evaporation process, such as uneven thickness, protrusions, etc. Such defective films are prone to excessive loss after being wound into a thin film electrode, and the product quality is difficult to control. Even cause the capacitor to explode

Embodiment Construction

[0019] refer to figure 1 , an intelligent capacitor film precision detection system proposed by the present invention, the capacitor is made of a plastic film with a metal layer on one side, and the system includes: N pressure detection modules, N pressure detection modules used in conjunction with the N pressure detection modules A distance record module, a blower module, a drive module, and a feedback module;

[0020] The blowing module is used to blow the plastic film so that the metallized layer of the plastic film is close to the N pressure detection modules and the N distance recording modules, and the wind direction of the blowing module is perpendicular to the plastic film.

[0021] In a specific solution, when the plastic film is not coated with a metal layer, the plastic film is blown with a wind perpendicular to the plastic film, so that the metal-plated layer of the plastic film is close to the pressure detection module.

[0022] The N pressure detection modules a...

Abstract

The invention discloses an intelligent capacitor film precision detection system. The system comprises a blowing module, N pressure detection modules, a driving module, N distance recording modules and a feedback module, wherein the blowing module is used for blowing on plastic film, so that a plated metal layer of the plastic film tightly fits the pressure detection module and the distance recording modules; the pressure detection modules are numbered, and the pressure detection modules are used for obtaining the pressure of the plastic film on the pressure detection modules; the driving module is used for driving the pressure detection modules and the distance recording modules to move along a length direction of the plastic film; the distance recording modules are used for recording distance values of the movement of the driving module; and the feedback module is used for feeding back a number of one certain pressure detection module and a distance value of the corresponding distance recording module used cooperatively with the pressure detection module when a pressure value detected by the pressure detection module is larger than a preset pressure threshold.

Description

technical field [0001] The invention relates to the technical field of capacitor detection, in particular to an intelligent capacitor film precision detection system. Background technique [0002] In the prior art, the common manufacturing method of film capacitors is to overlap metal film and plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wind it into a cylindrical metallized film electrode. Then it is placed in the capacitor case, injected with insulating oil and epoxy resin, and then assembled to obtain a film capacitor. Among them, the metallized film will have coating defects during the evaporation process, such as uneven thickness, protrusions, etc. Such defective films are prone to excessive loss after being wound into a thin film electrode, and the product quality is difficult to control. Even lead to capacitor explosion. Therefore, it is necessary to detect and adjust the evaporation effect of the metallize...
