Description
Technical field
The present invention relates to capacitor detection technique field more particularly to a kind of capacitor film quality determining methods.
Background technology
The great advantage of metalized film capacitance is " self-healing " characteristic.If so-called self-healing feature be exactly thin film dielectrics due to
Certain is put existing defects and puncture short occurs under overvoltage effect, and the metal layer of breakdown point can be in wink under arcing
Between fusing evaporation and formed very little without metal area, make two pole pieces of capacitance again mutually insulated and remain to continue work
Make, therefore greatly improves the reliability of capacitor work.In process of production, if metallized film exists during vapor deposition
Became uneven is even, the plating defects such as raised when, influence whether using effect and use of the film after being wound into membrane electrode
Service life, therefore, in order to ensure that the excellent service condition of capacitor, needs that the evaporation effect of metallized film is detected and is adjusted.
Invention content
Technical problems based on background technology, the present invention propose a kind of capacitor film quality determining method；
A kind of capacitor film quality determining method proposed by the present invention, the capacitor by a face metal cladding plastics
Film is made, the method includes：
S1, plastic film is flattened；
S2, pressure-detecting device is arranged in plastic film metal cladding one side, by blowing device to plastic film
It is blowed, the metal cladding of plastic film is made to be close to pressure-detecting device；
S3, driving pressure detection device are moved along the length direction of plastic film；
S4, the pressure value of statistics pressure-detecting device during the motion are more than the quantity M of preset pressure threshold value, according to M
Judge whether plastic film is qualified.
Preferably, in step S2, the pressure-detecting device detection zone is more than the width of plastic film.
Preferably, include at least one pressure sensor in step S2, on the pressure-detecting device.
Preferably, in step S2, blowing device is set to the non-metal cladding of plastic film, the wind direction of blowing device perpendicular to
Plastic film.
Preferably, step S4, it is described to judge whether plastic film is qualified, specifically includes according to M：
By M and predetermined threshold value M0It is compared, as M > M0When, judge that plastic film is unqualified；Otherwise, judge plastic film
It is qualified.
Preferably, step S4 further includes：
When judging that plastic film is unqualified, send a warning.
The present invention using blowing device makes plastic film, and metal cladding is close to pressure-detecting device, driving pressure detection dress
It sets and is moved along plastic film length direction, when there is protrusion on plastic film metal cladding, pressure-detecting device obtains
Real-time pressure value can be more than predetermined threshold value, when the quantity of the real-time pressure value more than predetermined threshold value be more than predetermined threshold value when, say
The quantity that bright plastic film has had protrusion on metal cladding is exceeded, and it is not excellent enough to make precision, judges plastic film for not
Qualified products quickly and effectively distinguish substandard product, improve the quality of the capacitor to come into the market, further,
Be conducive to relevant staff to be adjusted plastic film present situation, to ensure the quality of capacitor after processing.
Description of the drawings
Fig. 1 is a kind of flow diagram of capacitor film quality determining method proposed by the present invention.
Specific implementation mode
Referring to Fig.1, a kind of capacitor film quality determining method proposed by the present invention, the capacitor plate metal by one side
The plastic film of layer is made, the method includes：
Step S1, plastic film is flattened.
It is plastic film after metal cladding fold causes in order to prevent by plastic film flattening purpose in concrete scheme
There is error in continuous pressure detecting.
Pressure-detecting device is arranged in plastic film metal cladding one side, by blowing device to plastics by step S2
Film is blowed, and the metal cladding of plastic film is made to be close to pressure-detecting device, the pressure-detecting device detection zone
Include at least one pressure sensor more than the width of plastic film, on the pressure-detecting device, blowing device is set to plastics
The non-metal cladding of film, the wind direction of blowing device is perpendicular to plastic film.
In concrete scheme, in the non-metal cladding of plastic film, to be carried out to plastic film perpendicular to the wind of plastic film
Blowing, making plastic film, metal cladding is close to pressure-detecting device, wherein it is thin that pressure-detecting device detection zone is more than plastics
The width of film allows the metal cladding of plastic film can to the pressure of pressure-detecting device in the width direction of plastic film
It is detected comprehensively by pressure-detecting device.
Step S3, driving pressure detection device are moved along the length direction of plastic film.
In concrete scheme, driving pressure detection device is moved along the length direction of plastic film, and plastic film is made to exist
The pressure of pressure-detecting device can be detected by pressure-detecting device comprehensively on length direction.
Step S4, the pressure value of statistics pressure-detecting device during the motion are more than the quantity M of preset pressure threshold value, root
Judge whether plastic film is qualified, specifically includes according to M：By M and predetermined threshold value M0It is compared, as M > M0When, judge that plastics are thin
Film is unqualified；Otherwise, judge plastic film qualification.
This step further includes：When judging that plastic film is unqualified, send a warning.
In concrete scheme, pressure-detecting device during the motion pressure value be more than preset pressure threshold value when, illustrate to mould
Expect that film has protrusion on metal cladding, when the quantity of the pressure value more than predetermined threshold value is more than predetermined threshold value, illustrates to mould
Expect film existed on metal cladding protrusion quantity it is exceeded, it is not excellent enough to make precision, judges plastic film to be unqualified
Product reminds staff at this point, sending a warning.
Present embodiment using blowing device makes plastic film, and metal cladding is close to pressure-detecting device, driving pressure inspection
Device is surveyed to move along plastic film length direction, when there is protrusion on plastic film metal cladding, pressure-detecting device
The real-time pressure value of acquisition can be more than predetermined threshold value, when the quantity of the real-time pressure value more than predetermined threshold value is more than predetermined threshold value
When, illustrate plastic film existed on metal cladding protrusion quantity it is exceeded, it is not excellent enough to make precision, judges plastic film
For substandard product, quickly and effectively substandard product is distinguished, improves the quality of the capacitor to come into the market, further
, be conducive to relevant staff and the present situation of plastic film is adjusted, to ensure the quality of capacitor after processing.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
