Then, see through 101 pairs of ultraviolet hardening resin layer ultraviolet radiation device 14 irradiation ultraviolet radiations of base lens by metal die 9 moulding on base lens 101.Make the sclerosis of ultraviolet hardening resin layer by this ultraviolet ray irradiation.
At this moment, in this compound lens manufacturing installation, use the nitrogen introducing mechanism, with nitrogen import the ultraviolet hardening resin layer around.That is, in this compound lens manufacturing installation, the sclerosis of ultraviolet hardening resin layer is to carry out under the state around the nitrogen importing ultraviolet hardening resin layer.By the importing of nitrogen, the ultraviolet hardening resin layer that makes base lens 101 peripheral sides also can be rapidly, sclerosis effectively.
The nitrogen introducing mechanism imports the periphery of base lens 101 to nitrogen from the nitrogen steel cylinder of scheming not show, the periphery of process positioning component 2.On endless member 30, as shown in Figure 9, be provided with the through hole 32 that makes air effusion usefulness, like this, can import nitrogen effectively.In addition, the importing of nitrogen is to carry out simultaneously by the valve of operation nitrogen steel cylinder and ultraviolet irradiation time to the ultraviolet hardening resin layer.
In the nitrogen introducing mechanism, also shielding portion can be set, this shielding portion is used to prevent that the nitrogen that imports from making unhardened ultraviolet hardening resin layer distortion.This shielding portion can form like this: the wall segment that covers base lens 101 is set on the importing road of nitrogen.By this shielding portion, when importing nitrogen, can prevent that the nitrogen that imports from directly contacting unhardened ultraviolet hardening resin layer and making this ultraviolet hardening resin layer distortion.In addition, nitrogen imports road 33 and also can be located at metal die 9 sides as shown in Figure 9.
The sclerosis of ultraviolet hardening resin layer makes metal die 9 leave base lens 101 after finishing, and carries out the demoulding.When this demoulding, rotation motor 27 and lift motor 19 are driven, Yi Bian metal die 9 is pivoted, Yi Bian break away from base lens 101.Like this, on the lens face of base lens 101, form the ultraviolet hardening resin layer hardened, finished compound lens.
The invention effect
As mentioned above, in compound lens manufacturing installation of the present invention and the compound lens manufacture method, base lens is located and maintained in bail card division with positioning component, under the state that has carried out this positioning component and metal die, the ultraviolet hardening resin layer that is molded on the base lens by metal die is hardened with ultraviolet radiation device to the center.
Because positioning component and metal die are being kept by housing by linear guide and Throw bearing respectively, so even position the loading and unloading with respect to this housing of assembly and metal die, the position between positioning component and metal die can the changing of the relative positions yet.
Promptly, according to compound lens manufacturing installation of the present invention and compound lens manufacture method, on the face of glass base lens, form the ultraviolet hardening resin layer, when making the compound lens of lens as a whole, between the metal die of base lens and moulding ultraviolet hardening resin layer to the center, available easy operation is carried out exactly.
In addition, in compound lens manufacturing installation of the present invention and the compound lens manufacture method, on the face that is held the base lens that mechanism keeping, with metal die moulding ultraviolet hardening resin layer, when making this ultraviolet hardening resin layer sclerosis, around nitrogen importing ultraviolet hardening resin layer with ultraviolet radiation device.
Therefore, the ultraviolet hardening resin layer does not contact with air, available ultraviolet irradiation, make the ultraviolet hardening resin layer rapidly, effectively the sclerosis.
Promptly, according to compound lens manufacturing installation of the present invention and compound lens manufacture method, on the face of glass base lens, form the ultraviolet hardening resin layer, when making the compound lens of lens as a whole, can be rapidly and make the sclerosis of ultraviolet hardening resin layer effectively.
