Below bed die MD2, be formed with the driven pulley FW of the wheel shape rolled on cam surface CPa and rotatably support the support SP of driven pulley FW.
As shown in Figure 2, according to the position of rotation of the first disk DC1 and the second disk DC2, become the first handling part A, the second handling part B, the 3rd handling part C, the 4th handling part D.The point gum machine DSP that can spray light-cured resin is in right amount configured with at the first handling part A.Light source OPS is configured with at the second handling part B.The arm-type mechanical arm RB taking out in type optical element OE is configured with at the 4th handling part D.
The first mold component MD1a in Fig. 2 and the second mold component MD2a is amplified the figure represented by Fig. 3.As shown in Figure 3, first mold component MD1a entirety is discoid, in central authorities, there is curved first optical surface transfer surface MD1b, there is the first flange surface transfer surface MD1c of face wheel band shape around the first optical surface transfer surface MD1b, around the first flange surface transfer surface MD1c, be formed with cylindrical portion MD1d.The inner peripheral surface MD1e of cylindrical portion MD1d forms the first location division.In addition, the front end of cylindrical portion MD1d is the bearing surface MD1f as plane, is formed with the taper surface MD1g as chamfered section between inner peripheral surface MD1e and bearing surface MD1f.
On the other hand, the second mold component MD2a has: the second mold component MD2b, the air slide block AS being fixed on the ring-type of the second mould MD2, fixing maintenance second mold component MD2b by the support HLD of air slide block AS floating support.Second mold component MD2b entirety is discoid, has curved second optical surface transfer surface MD2c in central authorities, has the second flange surface transfer surface MD2d of face wheel band shape around the second optical surface transfer surface MD2c.Surrounding's formation drum of the second flange surface transfer surface MD2d, its outer peripheral face MD2e forms the second location division.The outside of outer peripheral face MD2e is the plane MD2f extended radially.
Air slide block AS passes through from the face blow out air relative with support HLD, can with low-frictional force floating support support HLD.
The manufacture method of the optical element of present embodiment is described.At this, be conceived to a pair mold MD1 and bed die MD2 and manufacture is described.First, by the confession electric drive actuator AC from not shown power supply, rotating shaft SFT is rotated, thus the first disk DC1 and the second disk DC2 is synchronously rotated.At this, at the leading portion of the first handling part A, the driven pulley FW of bed die MD2 is in the lower curtate CPb of the cam surface CPa of lobe plate CP, therefore, the first mold component MD1a of mold MD1 and the second mold component MD2b of bed die MD2 is in the state opened, therefore, via point gum machine DSP, light-cured resin PL can be made to drop on the second optical surface transfer surface MD2c.
Then, light-cured resin PL is supplied to middle mold MD1 and bed die MD2 to be moved by the synchronous rotary of the first disk DC1 and the second disk DC2.At this, the driven pulley FW of bed die MD2 rolls on the upward slope inclined-plane CPc of the cam surface CPa of lobe plate CP, and therefore, bed die MD2 moves closer to mold MD1.
Now, with reference to Fig. 4 (a), the axis AX2 of the axis AX1 of the first optical surface transfer surface MD1b of the first mold component MD1a and the second optical surface transfer surface MD2c of the second mold component MD2b departs from.As shown in Fig. 4 (b), when the second mold component MD2b is close to the first mold component MD1a, that the inclined-plane MD1g of the cylindrical portion MD1d of the first mold component MD1a abuts with the outer rim P of the second flange surface transfer surface MD2d in the second mold component MD2b at first, inclined-plane MD1g is subject to the power with the direction composition of axis vertical take-off from outer rim P, therefore, moved to optical axis orthogonal direction relative to the first mold component MD1a by each support HLD, the second mold component MD2b that air slide block AS supports and center, thus, make axis AX1, AX2 consistent.
Under the state that axis AX1, AX2 are consistent, bed die MD2 is further close to mold MD1, therefore, the outer peripheral face MD2e of the second mold component MD2b chimeric with the inner peripheral surface MD1e of the cylindrical portion MD1d of the first mold component MD1a (with reference to Fig. 4 (c)).
In fig. 2, when arriving the high portion CPd in the cam surface CPa of lobe plate CP at driven pulley FW, both touch and become matched moulds (back segment of the first handling part A).Now, as shown in Fig. 4 (c), the plane MD2f of the second mold component MD2b abuts with the bearing surface MD1f of the cylindrical portion MD1d of the first mold component MD1a, can guarantee the interval between the first optical surface transfer surface MD1b and the second optical surface transfer surface MD2c accurately.In addition, at driven pulley FW during high portion CPd rolls, the matched moulds state of mold MD1 and bed die MD2 can be maintained.
Then, mold MD1 and bed die MD2 maintains matched moulds state, while moved to the second handling part B by the synchronous rotary of the first disk DC1 and the second disk DC2.At this, the light penetrated from light source OPS arrives light-cured resin PL via mold MD1, and light-cured resin PL is solidified.Mold MD1 and bed die MD2 passes through the below of the multiple light source OPS be fixed, and therefore, by irradiating light from all directions, can guarantee the uniform curing of the curable resin given in the chamber of mold MD1 and bed die MD2.
In addition, mold MD1 and bed die MD2 is moved to the 3rd handling part C by the synchronous rotary of the first disk DC1 and the second disk DC2.At this, the driven pulley FW of the bed die MD2 descending inclined-plane CPe in the cam surface CPa of lobe plate CP rolls, and therefore, bed die MD2 separates with mold MD1 gradually, thus, carries out die sinking.
After driven pulley FW terminates rolling on descending inclined-plane CPe, again roll on lower curtate CPb, therefore, the first mold component MD1a of mold MD1 and the second mold component MD2b of bed die MD2 maintains the state opened, therefore, then at the 4th handling part D, stretch by making the arm of mechanical arm RB, in type optical element OE can be taken out, and be delivered in other operation.Above, be conceived to a pair mold MD1 and bed die MD2 and describe shaping, but other mold MD1 and bed die MD2 also carry out identical molding procedure on opportunity of staggering, therefore, high-precision optical element OE can be produced in a large number.
Fig. 5 is the sectional view of the example representing the optical element OE manufactured by the manufacturing installation of present embodiment.The first optical surface S1 of optical element OE is formed by the first optical surface transfer surface MD1b transfer printing of the first mold component MD1a, the first flange surface FL1 of flange part FL is formed by the first flange surface transfer surface MD1c transfer printing, and the outer peripheral face FL3 of flange part FL is formed by the inner peripheral surface MD1e transfer printing of cylindrical portion MD1d.On the other hand, the second optical surface S2 of optical element OE is formed by the second optical surface transfer surface MD2c transfer printing of the second mold component MD1b, and the second flange surface FL2 of flange part FL is formed by the second flange surface transfer surface MD2d transfer printing.
Fig. 6 is the figure of the molding procedure representing the first mold component that the manufacturing installation of present embodiment uses.First, the master mold MM corresponding with the first mold component is formed.As shown in Fig. 6 (a), the raw material such as super-steel are installed on rotating disk etc., rotate the rotary cut utilizing cutting element T to carry out female transfer surface.Thus, master mold MM is formed female optical surface transfer surface MMa, female flange surface transfer surface MMb and female location division transfer surface MMc.
Then, as shown in Fig. 6 (b), master mold MM is carried out matched moulds relative to the end face of another mould MM2, supply the thermoplastic resin HPL of melting to the space (chamber) resulting from inside.Then, carrying out heating and resin HPL being solidified, as shown in Fig. 6 (c), by making master mold MM from another mould MM2 demoulding, the first mold component MD1a can be obtained.The the first mold component MD1a obtained by such injection-molded resin is had: by transfer printing molded the first optical surface transfer surface MD1b of female optical surface transfer surface MMa, by transfer printing molded the first flange surface transfer surface MD1c of female flange surface transfer surface MMb, by the transfer printing molded cylindrical portion MD1d of female location division transfer surface MMc.Then, as shown in Fig. 6 (d), the first mold component MD1a is installed on as on the mold base MD1f (by engaging, becoming mold MD1) of glass baseplate.In addition, when injection moulding, as shown in Fig. 6 (e), also can one-body molded with mold base MD1f be the first mold component MD1a.Thus, do not need glass baseplate, and do not need the joint of mold base MD1f and the first mold component MD1a.
Also can use master mold MM, be that raw material form the first mold component MD1a with glass.In this case, the shaping or glass thermoforming again of glass mold is adopted.
Fig. 7 is the figure of the variation representing location division.Compared to above-mentioned embodiment, the outer rim of the second flange surface transfer surface MD2d in the second mold component MD2b is set to taper surface MD2g by the variation of Fig. 7 (a).Thereby, it is possible to more easily carry out the chimeric of the second mold component MD2b and the first mold component MD1a.
The difference of the variation of Fig. 7 (b) is, the inner peripheral surface of the cylindrical portion MD1d of the first mold component MD1a is set to taper surface MD1e, and the outer peripheral face of the second mold component MD2b is set to taper surface MD2e.During matched moulds, taper surface MD1e, MD2e are against each other chimeric.
In the variation of Fig. 7 (c), the inner peripheral surface of the cylindrical portion MD1d of the first mold component MD1a is set to taper surface MD1e, but the outer peripheral face MD2e of the second mold component MD2b is directly set to barrel surface.During matched moulds, taper surface MD1e abuts with the outer rim P of the second flange surface transfer surface MD2d in the second mold component MD2b.
Fig. 8 is the first mold component of another embodiment and the stereogram of the second mold component, and the structure of Fig. 8 is cut off with IX-IX line and the figure observed with the direction of arrow by Fig. 9.In present embodiment, between the first mold component MD1a and the second mold component MD2b, configure the pad SPS of tabular.
In Fig. 9, be formed with the projection MD2h of roughly crescent shape in the both sides of the second flange surface transfer surface MD2d of the second mold component MD2b.The lateral surface MD2i of projection MD2h is the local barrel surface of formation second location division, and inner side is plane MD2j.Second flange surface transfer surface MD2d arranges pad SPS in the mode abutted with plane MD2j both sides.Pad SPS has open S PSa in central authorities.
The concavity of the lower surface of the first mold component MD1a becomes shallow disc shape, be formed with the first optical surface transfer surface MD1b and the first flange surface transfer surface MD1c in this its bottom surface, be formed with the otch MD1h of the width of pad SPS in the radial both sides of the first flange surface transfer surface MD1c.The outside of otch MD1h becomes the protuberance MD1i of roughly crescent shape.The inner peripheral surface MD1j forming the protuberance MD1i of the second location division is partial cylinder face, with the same footpath of lateral surface MD2i of projection MD2h.
If supply light-cured resin and carry out matched moulds in the open S PSa of pad SPS, first mold component MD1a and the second mold component MD2b is close to each other, the lateral surface MD2i of projection MD2h is chimeric with the inner peripheral surface MD1j of protuberance MD1i, thus, the first optical surface transfer surface MD1b becomes consistent with the axis of the second optical surface transfer surface MD2c.In addition, the first flange surface transfer surface MD1c of the first mold component MD1a and the upper surface of pad SPS are adjacent to.Then, by irradiating light from the first mold component MD1a side, make inner light-cured resin solidification, can shaping optics.Now, the outer peripheral face of the open S PSa shaping optics of pad SPS is utilized.In addition, pad SPS also can be used as the carrier of the in type optical element of conveying.
The invention is not restricted to the embodiment described in this description, the embodiment described in this description or technological thought, the practitioner of this area obviously can understand and also comprises other embodiment, variation.
