(the main effect of present embodiment)
As discussed above, in the transfer device 70 of the module punching device 1 of present embodiment, repeating to rise, to advance, to descend, to retreat by carriage 71a, 71b is moving of one-period, and a plurality of shaping pieces are risen simultaneously, and constantly transfer off and on length by length along transfer direction by carriage 71a, 71b.For this reason, can the vibration suppression of the shaping piece 50 in transferring is extremely minimum.Therefore, because the position of (in the shaping die 51) raw shaping material does not misplace on shaping piece 50, therefore can suppress the bad of face shape that the uneven thickness by raw shaping material causes, and, can stably produce high-precision optical element by bad etc. the generation of the inhomogeneous surface accuracy that causes of load.
In addition, shaping piece 50, owing to only contact with carriage 71a, 71b in handover, therefore when being shifted into arbitrary place, mutual contact area all position is certain.Correspondingly, because shaping piece 50 is all only accepted equal temperature variation when being shifted into any place, therefore can carry out the temperature treatment of each handling part iwis.Therefore, can seek the raising of forming accuracy.In addition, as long as owing in handling part, guarantee to make the space of carriage 71a, 71b action, therefore can be with unnecessary space reduction, and miniaturization that can implement device.
In addition, because shaping piece 50 has test portion platform 55 and shaping die 51, and carriage 71a, 71b transfer shaping piece 50 by the bottom surface that is connected to test portion platform 55, thereby carriage 71a, 71b directly do not contact shaping die 51, so can avoid mutual temperature to interfere.Therefore, can carry out the temperature treatment in each handling part definitely, the stabilization of the densification that thus can implement device and the precision of optical element.
In addition, carriage 71a, 71b are connected to and depart from the position of its central axis in the bottom surface of shaping module 50 and shaping piece 50 is risen, thereby in shaping piece 50, can not form the handover of piece 50 with the position of accepting shaping load with producing location conflicts.
Also have in addition, in the present embodiment, transfer device 70, being constituted as carriage 71a, 71b carries out carrying out forward motion after the vertical motion, and in any action of carrying out vertical motion, forward motion and down maneuver, the speed of when beginning action and release eve all is set to, than from each action begin to the speed the intergrade that finishes slow.For this reason, can be minimum with the vibration suppression of shaping piece 50 and raw shaping material.
(other embodiment)
Other embodiment of the present invention are described.Preferably between carriage 71a, 71b and shaping piece 50, be assembled with the anti-locking mechanism of location dislocation of shaping piece 50 location dislocations that prevent carriage 71a, 71b surface.As the anti-locking mechanism of this location dislocation, can utilize for example magnetic attraction.For example, shown in Fig. 5 (a) like that, at the position that the shaping piece with carriage 71a, 71b keeps, form shaping piece 50 by the recess 71c of sliding embedding, and in these recesses 71c configuration permanent magnet 71d.In addition, in shaping piece 50, test portion platform 55 is made of the magnetic material of stainless steel (stainless steel) etc.Constitute if so, the piece 50 that then is shaped is positively carried, is remained on carriage 71a, the 71b, and does not produce location dislocation in handover.
In addition, shown in Fig. 5 (b), permanent magnet 71d also can be arranged at the side of shaping piece 50 (the platform 55-1 of test portion platform 55).Under the situation of considering carriage 71a, 71b thermal expansion, the recess 71c of preferred carriage 71a, 71b keeps surplus and formation significantly than the mounting surface of shaping piece 50.
According to the anti-locking mechanism in the position that utilizes this magnetic force, different with the anti-locking mechanism of the location dislocation of machinery, can shaping piece 50 be risen from the fixed support platform by carriage 71a, 71b.In addition, when it makes carriage 71a, 71b and 50 thermal distortions of shaping piece from driving beginning along with the repetition of punching press number of times, if mechanically chimericly then can not play a role, if but magnetic attraction then has and constantly brings into play the advantage that location dislocation prevents function.
In addition, in the example shown in Fig. 5 (a), form the structure of test portion platform 55 contact permanent magnet 71d.In contrast, also can adopt following structure, promptly reduce recess 71c, test portion platform 55 and permanent magnet 71d are non-contacting state still, and prevent the location dislocation of the shaping piece 50 on carriage 71a, the 71b by magnetic attraction.
In addition, as the anti-locking mechanism of the location dislocation of the location dislocation that prevents the shaping piece 50 on carriage 71a, the 71b, also can be by implementing processing such as asperitiesization at least one side in the position of the maintenance shaping piece 50 of the bottom surface of shaping piece 50 and carriage 71a, 71b, and improve friction resistance.In addition, also the location dislocation that utilizes this frictional force can be prevented to be combined in based in the anti-locking mechanism of the location dislocation of above-mentioned magnetic attraction.
In addition, in the above-described embodiments, though the action that carriage 71a, 71b rise independently, advance, descend, retreat, while the progressive action of for example also can carrying out rising, while or the action that descends and retreat.In addition, though the motion track of carriage 71a, 71b is a rectangle, being not limited thereto, also can be for example oval, oval and just round.
