Fig. 3 is the figure of the configuration relation illustrating CCD camera 40 (first camera 40a, second camera 40b) and treatment tube 31. In the following description, enumerate and two CCD camera 40a be configured with film cross direction, the example of CCD camera 40b illustrates, But the configuration number not limited to this of CCD camera.

The configuration number of CCD camera correspondingly suitably can change according to the size of the visual field width of CCD camera, film width. For example, it is also possible to increase the configuration number of CCD camera in the case of wanting to improve resolution, and made by changing in CCD camera With lens reduce visual field width.

It should be noted that it is also possible to make the resolution of the film cross direction of CCD camera in the case of carrying out sided corona treatment For 100 μm/pixel about.

In figure 3, reference AR1 is region (below, the sometimes referred to as film conveying of the feeding optical film in treatment tube 31 Region.).Reference AR2 be the both ends for the treatment of tube 31 not the region of feeding optical film, i.e. the surface for the treatment of tube 31 expose Region (below, sometimes referred to as roller exposed area.).Reference W1 be the length of film conveyor zones AR1 on film cross direction, I.e. width (below, the sometimes referred to simply as film width of blooming.).Reference W2 is roller exposed area AR2 on film cross direction Length.Reference W3 is the total length of the length for the treatment of tube 31 on film cross direction, i.e. treatment tube 31.Reference Wa is two The visual field width of first camera 40a in individual CCD camera 40.Reference Wb is the visual field width of second camera 40b.Accompanying drawing mark Note CL is centrage (below, the sometimes referred to simply as centrage for the treatment of tube 31 on film cross direction.).

In the present embodiment, film width W1 is 1500mm, and total length W3 for the treatment of tube 31 is 1800mm, CCD camera 40a The visual field width Wb of visual field width Wa and CCD camera 40b is respectively 760mm.

Two CCD camera 40a, CCD camera 40b consider that the sinuous amplitude of film is configured to shoot film width entirety.In this reality Apply in mode, first camera 40a is configured to shoot film conveyor zones AR1 of the -X direction side (left side) for the treatment of tube 31, the second phase Machine 40b is configured to shoot film conveyor zones AR1 of the +X direction side (right side) for the treatment of tube 31.

Specifically, first camera 40a is configured to the edge (edge on right side) of the +X direction side of visual field width Wa and is located at Centrage CL.The edge (edge in left side) that second camera 40b is configured to the -X direction side of visual field width Wb is located at centrage CL. It should be noted that the end (end on right side) of the +X direction side of visual field width Wa of first camera 40a and second camera 40b The -X direction side of visual field width Wb end (end in left side) can also near centrage CL part superposition.

Thus, even if blooming is advanced tortuously (sinuous amplitude 10mm) it is also possible to make the overall width of blooming (1500mm) in the visual field width (visual field width 760mm and second by first camera 40a of CCD camera 40a, CCD camera 40b The visual field width 760mm of camera 40b is added the width 1520mm of gained) in the range of.

If in addition, can make blooming overall width be in CCD camera 40a, CCD camera 40b visual field width model In enclosing, then can detect the light quantity of the discharging light of corona discharge exactly throughout the whole width of blooming.

According to the research of the present inventor, it is clear that, deposit between the intensity of discharge current density and intermembranous bonding force In high correlation.In addition, also specify that, there is high correlation between discharge current density and the light quantity of discharging light, especially can The deviation of the light quantity of discharging light is enough accurately detected using CCD camera.Though its reason is failed to understand, it is considered, CCD camera is by light It is converted into the signal of telecommunication, the light quantity due to discharging light changes according to discharge current density, therefore for both sides, produce above-mentioned The mechanism of dependency is similar.Thus, if detect the distribution of the light quantity of discharging light in the face of blooming using CCD camera, can Enough underproof generating unit of laminating being caused because intermembranous bonding force is not enough with high-precision forecast, be can aid in and be manufactured into The raising of product rate.

Hereinafter, discharge current density and discharging light are described.

Discharging light is produced with gas molecule collision by the charged particle released from sparking electrode.

By improving discharge current, give energy (kinetic energy and internal energy sum) to more charged particles.Its result It is that charged particle is increased with the collision energy of gas molecule, and the light quantity of discharging light is consequently increased.

The energy balance actually represents as follows：Electric discharge energy=each charged particle energy (kinetic energy with interior Portion's energy sum) × charged particle number+radiation+conduction of heat.

Because the more big then electric power of electric current is bigger, therefore, though the average energy of each charged particle (Temperature) fixing, by Increase in the larger charged particle of energy, therefore radiation increases.In fact, when the current increases, temperature changes because of heating, because And the internal energy change of charged particle.Thus, radiation increases, and conduction of heat also increases simultaneously.

Exist from the radiant density of the material stefan boltzmann's law proportional to 4 powers of temperature. Because radiation is the total emission energy obtaining the whole spectrum additions comprising the visible region that human perception is light, therefore put Penetrate the luminous of the spectral sensitivity region that will not be wholly converted into the only visible ray of human perception or CCD element.Due to being energy The total amount of density, therefore radiation is proportional to the surface area of luminous body.

Thus, energy be not all converted to luminous, so luminous quantity proportional to electric current or electric current density or with square Proportional etc. uniquely can not be represented with relational expression.

The information of the light quantity of discharging light is related to the positional information of the long side direction of blooming and width, for example, make For image mapping, it is stored respectively in storage part and the check device 4 of DCS6.Thus, easily in applying system described later Except the light quantity of discharging light does not control the part in suitable scope (to produce abnormal in corona discharge, suitably do not carry out surface The part of modification：Unusual part), part in suitable scope for the fader control of discharging light (is not produced in corona discharge Abnormal, it is appropriately the part of surfaction：Part without exception) it is used in product.

It should be noted that the light quantity that can also not remove discharging light in applying system described later does not control suitable The part (unusual part) of scope, even if there is unusual part also not regarding as unqualified for the time being, but emphasis checks final producing Product come to confirm quality aspect whether there is problem.

Next, the inspection of the light quantity of the discharging light of corona discharge that explanation is carried out by the check device 4 of present embodiment.

Fig. 4 A, Fig. 4 B be illustrate by electric discharge output be set as the blooming in the case of 800W width position with The figure of the relation of light quantity grade.

Fig. 4 A be every 999.9 microseconds implement single pass (acquisition of data) and by the light quantity data of a minute, i.e. 1000 time/second × 60 second=60000 time light quantity data are continuously drawn on the figure of same chart (being repeatedly written).

Fig. 4 B is the figure of the data of the single pass illustrating not being repeatedly written.

In Fig. 4 A, Fig. 4 B, transverse axis represents the position of the width of blooming, and the longitudinal axis illustrates light quantity grade as CCD The photosensitive light quantity of the corona discharge light that camera 40 receives.

Here, light quantity grade illustrates the photosensitive light quantity of corona discharge light with 256 GTGs.It should be noted that not with CCD phase Light quantity grade is represented based on the data of photosensitive light quantity of the corona discharge light that machine receives, i.e. so-called initial data, and with Light quantity grade is represented based on initial data is eliminated with the data after the effect of noise such as illumination light (rationalization data).

Fig. 4 A, the transverse axis of Fig. 4 B are corresponding with the visual field width (760mm) of a CCD camera in two CCD camera 40, if with Pixel represents, is equivalent to 4096pixel.Fig. 4 A, the longitudinal axis of Fig. 4 B illustrate 256 GTGs, in Figure 4 A, make under light quantity grade Limit value is that 0, higher limit illustrates for 255.

As shown in Fig. 4 A, Fig. 4 B, the meansigma methodss of the light quantity grade in the case that electric discharge output is set as 800W are 127, It is the substantially half of 256 GTGs.Light quantity grade is in the width whole region of blooming to a certain degree to change.Work as observation During the width whole region of blooming, the mobility scale of light quantity grade is 97～156.As shown in Figure 4 A, light quantity grade Mobility scale is in that banding extends in the width whole region of blooming.

But, the difference of the position of the width according to blooming, the mobility scale of light quantity grade is different.For example, exist Be equivalent at the position of pixel 600pixel on the width of blooming, the lower limit of light quantity grade is lower than other positions.That is, On the width of blooming, the discharge current density of corona discharge diminishes, and the surface that may fully not carry out blooming changes Matter.

In the present embodiment, by the setting up and down of the light quantity grade in the case that electric discharge output is set as 800W Threshold value is such that it is able to be judged as normal, in light in the case that light quantity grade is included in the range of by upper and lower prescribed threshold Amount grade is not included in by being judged as exception in the case of in the range of upper and lower prescribed threshold.For example, by than light quantity grade The value of meansigma methodss 127 low 50 is 77 to be set as threshold value, if on the width of blooming, under the mobility scale of light quantity grade Limit value is included in (situation that is identical with threshold value or being higher than threshold value) in the range of with threshold value as lower limit, then will be identical with threshold value or high Part in threshold value is judged as normally, in the situation in the range of with threshold value as lower limit that is not included in (less than the situation of threshold value) Under, the part that will be less than threshold value is judged as exception.

It should be noted that can also be, it be not only the mobility scale of light quantity grade on the width of blooming Lower limit is less than the situation of threshold value, the higher limit of the mobility scale of light quantity grade or meansigma methodss on the width of blooming In the case of threshold value, the part that also will be less than threshold value is judged as exception.

The information related to the light quantity of discharging light is with related with the position of the long side direction and width of blooming Information sets up the storage part that the mode associating is stored in DCS6.And, in applying system described later, read these from storage part Information, the blooming that will be deemed as the abnormal part of light quantity grade is excised as unqualified position, is reclaimed by retracting device.By This, the generation of the laminating causing because of sided corona treatment unqualified (the intermembranous laminating caused by bonding force deficiency is unqualified) is pressed down System, is provided that the manufacture system of high yield rate.

As described above, the manufacture device 1 of the blooming according to present embodiment, light can be checked by check device 4 Learn the distribution of the discharging light of corona discharge in the face of film.According to the research of the present inventor, the distribution of discharging light with put There is high correlation between the distribution of electric electric current density, and, the intensity of discharge current density and surfaction (intermembranous is bonding Power) between there is high correlation.Therefore, by obtaining the distribution of discharging light, can be pre- to before liquid crystal panel laminating blooming Survey the underproof generating unit of laminating causing because intermembranous bonding force is not enough, can aid in raising fabrication yield.

Further, since check device 4 possesses carries out photosensitive CCD camera 40 to corona discharge light, therefore, it is possible in real time The light quantity of the discharging light of corona discharge is checked.In addition, according to this structure, need not separately checking and implement sided corona treatment The wettability of the surface of blooming.Therefore, it is possible to simply and rapidly be confirmed whether uniformly implementing in blooming Sided corona treatment.

It should be noted that in the present embodiment, as one to electric discharge output is set as 800W in the case of The position of the width of blooming is illustrated with the relation of light quantity grade, but not limited to this.For example, electric discharge output removes this 1200W, 1000W, 600W, 400W, 300W, 230W etc. can also be set as according to suitable needs in addition.So, changing It is also possible to apply the present invention in the case of the setting value of electric discharge output.
