Close to the position of this irradiation unit 24 on direction, the underface Z of irradiation unit 24.This wavelength limits and filters
Device 33 cuts off the light of the wavelength that the photocuring to the light-cured resin 39 solidifying object does not contributes, should
Wavelength restricting filters 33 is arranged in from irradiation unit 24 to focus F, and is formed as covering housing 31
The overall size shape of irradiation opening 31A (Fig. 1).
First reflector 26 and the second reflector 27 are the reflection parts irradiating light to carrying face 3A obliquely.
Specifically, as it has been described above, be coated with in the rear side of the marginal area 18 of touch panel display 2
The light-cured resin 39 of solidification object.Thus, when irradiating light from the face side of touch panel display 2,
Marginal area 18 works, due to marginal area 18 as the lightproof area (not transmissive portions) blocking light
Shading and produce solidification bad.
Especially, in touch panel display 2, as shown in Fig. 3 (A) and Fig. 3 (B), due to this limit
Edge region 18 also includes the limit of wider width, the therefore light-cured resin of the rear side on the limit of this wider width
Easily produce solidification bad.In this case, although can by touch panel display 2 is overturn and from
Display floater 8 side (i.e. rear side) is again carried out light and irradiates that to reduce solidification bad, but so, needs
Irradiating at least twice, therefore volume of production is deteriorated, it addition, there is a problem in that: even if by workpiece
Upset is irradiated, and there is also because electrical connection distribution, installing component cause irradiating the position that light cannot arrive.
Then, in order to realize inhibiting solidification not by once being irradiated by formula of being carried out by Handling device 4
Good photocuring processes, following this photocuring system 1 of composition.
That is, photocuring system 1 is not that directly the touch panel display 2 in carrying irradiates above-mentioned irradiation dress
Put the light of 24, but as shown in Figure 4, possess be arranged on direction, the underface Z of this irradiation unit 24 and
First incident for the irradiation light H1 reflector 26 of irradiation unit 24, this first reflector 26 is towards carrying
Direction A reflected illumination light H1, and the reflection light D1 produced by this reflection is exposed to touch panel display
2。
Additionally, light in this photocuring system 1 on carrying direction A relative to the optical axis of irradiation unit 24
C has the relation of mirror image.In other words, the optical system of photocuring system 1 has phase on carrying direction A
Optical axis C symmetrical structure for irradiation unit 24.In this irradiation unit 24, utilize from linear light source
The axle that the center O of 28 extends to direction, underface Z defines optical axis C.
It addition, the first reflector 26 is configured to as follows: relative with do not produce between irradiation unit 24
The mode of position skew, on direction, the underface Z of irradiation unit 24, utilizes not shown fixed component solid
Fixed.
More specifically, the first reflector 26 has relative to carrying face 3A with inclining that the angle of regulation tilts
Oblique incidence reflecting surface 40, reflects the irradiation from surface from this first reflector 26 towards the distant place of transport road 3
The irradiation light H1 of device 24 incidence.
Oblique incidence reflecting surface 40 has and extends parallel to the touch surface for being used for workpiece with linear light source 28
The shape that panel display 2 is longer.
Fig. 5 and Fig. 6 is the explanatory diagram of the radiation modality of the light during carrying representing touch panel display 2.
Additionally, in Figure 5, represent and including carrying on the face of direction A cuing open of touch panel display 2 of cutting
View.
As it has been described above, the edge 8B of the display floater 8 possessed in touch panel display 2, it is coated with light
Curable resin 39, the marginal area 18 of the panel 10 that is touched on the upside of this covers.This touch panel display
The 2 workpiece holding station 42 that touch panel 10 side (face side) is handled upside down road 3 upward keep and carry.
It addition, in this workpiece holding station 42, as shown in Figure 6, with rectangular box-like marginal area 18
The attitude that two limit 18A is parallel with carrying direction A, two other limit 18B is orthogonal with carrying direction A keeps
Touch panel display 2 is also carried.
As it has been described above, by the first reflector 26 to carry out reflecting by the way of the distant place of carrying direction A
Reflection light D1 exposes to the carrying face 3A of photocuring system 1.Owing to this reflection light D1 is incident to remove obliquely
Fortune face 3A, therefore, as it is shown in figure 5, be incident to the transmissive portions of touch panel display 2 obliquely the most effectively
Region 16, and arrive the light-cured resin 39 at the back side of marginal area 18, and this light-cured resin
39 by this reflection light D1 by photocuring.
It addition, in this touch panel display 2, touch panel 10 is configured to more than display floater 8.Cause
This, as it is shown in figure 5, the marginal area 18 of touch panel 10 edge compared with the edge 8B of display floater 8 is removed
Fortune road 3 extends out, and for the light irradiated from face side, plays the effect of the so-called the brim of a hat.Therefore, from
The reflection light D1 of touch panel display 2 is incided in the edge of the outer circumferential side of marginal area 18 i.e. outer rim 18T side
Blocked by this marginal area 18, do not arrive light-cured resin 39.
In other words, the photocuring of light-cured resin 39 is mainly by from effective district of touch panel display 2
The reflection that territory 16 (that is, from the edge of the inner circumferential side of marginal area 18 i.e. inner edge 18V side) is incident obliquely
The irradiation of light D1 produces.But, at light-cured resin 39 by the inner edge 18V of marginal area 18 it is
Benchmark (x=0) and till the direction of outer rim 18T is coated to deeper position (x=Wb) in the case of,
Solidification is easily produced owing to irradiating deficiency in light quantity bad in this outer rim 18T side.
Especially, in this touch panel display 2, it is as noted previously, as from the incidence of outer rim 18T side
Reflection light D1 is blocked by marginal area 18, therefore solidifies bad problem obvious.
Then, in this photocuring system 1, the incident angle θ of this reflection light D1 is set, so that from interior
Coating position Wb of the light-cured resin 39 of the reflection light D1 arrival outer rim 18T side that edge 18V side is incident.
Thickness based on light-cured resin 39 i.e. curing materials thickness b, coating position Wb, effective coverage 16 is (i.e.
Transmissive portions) refractive index calculate the value substantially of this incident angle θ.Inventor has obtained following opinion:
In the laminating of this touch panel display 2, when incident angle θ is of about 80 degree, ultraviolet arrives fully
Reach coating position Wb.Then, in this photocuring system 1, with the light component of incident angle θ=80 degree with
The regulation ratio mode in reflection light D1 contained above, carries out optical design to oblique incidence reflecting surface 40.
Thus, even if outer rim 18T of edge region 18 extends out as the brim of a hat and from this outer rim
In the case of the reflection light D1 of 18T inclination tiltedly incidence is blocked, from 18V side, inner edge, (i.e. transmissive portions) enters
The reflection light D1 penetrated arrives the outer rim 18T side of light-cured resin 39 fully, therefore can suppress to solidify not
Good.
It addition, as shown in Figure 6 above, under the carrying state of touch panel display 2, marginal area 18
Limit 18A extend, and relative to the oblique incidence reflecting surface 40 of the first reflector 26 along carrying direction A
Extend in an orthogonal manner.Therefore, from the first reflector 26 to carrying direction A advance substantially in parallel anti-
Penetrate light D1 and can not enter sufficiently into the rear side of this limit 18A, the photo-curable tree of the rear side of limit 18A
It is bad that fat 39 produces solidification.
Then, in this photocuring system 1, as shown in Figure 6, reflection light D1 is except including and carrying direction
The light component D1a that A advances abreast, also includes having the angle of 0～90 degree relative to this carrying direction A
Degree mode advance (that is, from oblique incidence reflecting surface 40 towards carrying face 3A width B) light
Components D 1b.
Specifically, in this photocuring system 1, as shown in Figure 6, the light source of irradiation unit 24 is and removes
Transport the linear light source 28 that direction A extends orthogonally, and oblique incidence reflecting surface 40 is configured to and wire
Light source 28 extends at least than the touch panel displays in carrying state (i.e. along width B) abreast
The width Wc of the width B of device 2 is longer (i.e. width is wider).
By making oblique incidence reflecting surface 40 extend along the width B of transport road 3, can not only be to from line
The irradiation light H1a that shape light source 28 is advanced to direction, underface Z reflects, additionally it is possible to relative to underface
The irradiation light H1b that direction Z advances with angle [alpha] (α ＞ 0) reflects.This irradiation light H1b is carried out instead
The light component D1b of the reflection light D1 penetrated, with irradiate light H1b the corresponding angle of angle [alpha] along transport road 3
Width B (i.e. towards carrying face 3A side 3A1) advance.
Exposing to touch panel display 2 by this light component D1b, light component D1b enters from 18V side, inner edge
It is mapped to along the limit 18A of carrying direction A extension, therefore, it is possible to utilize light component D1b to make to be coated in this
Light-cured resin 39 photocuring fully of the rear side of limit 18A.
It addition, in this light component D1b, with the light component D1a of the reflection light D1 advanced along carrying direction A
Similarly, also including the light of above-mentioned incident angle θ, therefore, in the 18A of limit, light component D1b also arrives at
The outer rim 18T side of light-cured resin 39, can be adequately suppressed solidification bad.
