Recently, digital camera, camera phone, web camera, etc. have become smaller and thinner, and the size of camera module is gradually decreasing. As the camera module is miniaturized, the demand for aspheric lenses instead of conventional spherical lenses is greatly increased.

Such an aspherical lens can be produced by a grinding method or a press molding method, and the grinding method is unsuitable for mass production. Therefore, recently, a press molding method in which a raw material is placed in an upper mold and a lower mold, the upper mold and the lower mold are assembled together, and the mold is mounted on a molding machine and molded through a high temperature heating process, a pressing process and a cooling process.

For example, Korean Patent Laid-Open No. 10-2006-0001861 discloses an example of an automatic lens forming apparatus for press forming as shown in Fig.

In the automatic lens molding apparatus described in the above-mentioned prior art, the mold taken out from the lens molding apparatus is disassembled, the mold lens is taken out, the mold is placed on the lens alignment plate, the new raw material is put into the disassembled mold, And a rectangular coordinate type robot for sequentially aligning the molding lenses arranged on the carry-out robot and the lens alignment plate to the lens holder and aligning the original material sequentially from the new original holder to the original material alignment plate.

However, since the lens aligning plate and the original material aligning plate are arranged in a fixed state close to each other, it is possible to prevent collision with the carry-in / carry-out robot while the carry-in / carry- Cartesian co-ordinated robots do not work.

Therefore, it is not possible to carry out the operation of transferring the raw materials in the raw material holder to the raw material alignment plate, which causes an increase in the entire lens molding cycle period.

The mold gripping portions 173 are formed so that the surfaces facing each other are rounded so as to cover the outer surface of the mold. The pair of mold gripping portions 173 can be gripped by the close proximity of the mold by the cylinder .

The finished article suction unit 176 is configured to suck the finished article by generating a suction force. The finished article suction unit 176 is opened in the lower direction to generate a suction force in the upward direction, so that the finished article of the lens can be sucked to the lower end.

The finished product suction unit 176 is preferably configured to selectively control generation and elimination of a suction force.

As described above, the ball lens transit apparatus 100 is configured so as to include a mold receiving portion 172 for transferring the mold and a lens receiving portion 175 for transferring the finished lens product, and the cooperative robot 110, It is possible to reduce the size of the ball lens transferring apparatus 100 itself.

Hereinafter, the detailed structure of the mold position adjustment unit 120 will be described with reference to FIG.

7 is an enlarged perspective view showing a mold position adjusting unit 120 which is a component of the ball lens transferring apparatus 100 according to the present invention.

As shown in the drawing, the mold position adjusting unit 120 is formed in a columnar shape and rotatable by itself, and has a mold seating part 122 on which a mold is seated on the upper surface, A planar position adjustment section (124) for making a movement in a planar direction by making contact with an outer surface of the mold by reciprocating motion, and an angle adjustment section (128) for adjusting the mold mount section (122) do.

The mold seating part 122 is configured to be rotatable in a state where a metal mold is seated on the upper surface and is maintained at a constant height. The mold seating part 122 is held on the upper surface by a mold gripping part 173, The transferred mold is in a stable state.

A planar position adjustment unit 124 is located at a position spaced apart from both sides of the mold seating unit 122. The plane position adjustment unit 124 adjusts the outer surface of the mold, which is seated on the upper surface of the mold seating unit 122 and can not move in the height direction, to be placed at a set position.

More specifically, the planar position adjustment unit 124 includes a one-directional restriction unit 125 for selectively restricting one-direction movement of the mold by selectively contacting the outer surface of the mold, And an orthogonal direction restricting section (126) for limiting movement in a direction orthogonal to the restricting direction of the one-direction restricting section (125) by contact.

The one-direction restricting portion 125 is located on the left side of the mold seating portion 122 and extends in the right direction so as to push the outer surface of the mold in the right direction.

Therefore, when the right end of the one-way limiter 125 is located at the rightmost position, the movement of the mold in the left direction can be restricted.

The orthogonal direction restricting portion 126 is operated simultaneously with the one-direction restricting portion 125 and is extended in the opposite direction so that the left side portion is in contact with the outer surface of the mold at a plurality of locations, Direction).

Therefore, the orthogonal direction restricting portion 126 and the inner end portions of the one-direction restricting portion 125 come close to each other and come in contact with the outer surface of the mold at three places, so that the mold can be set at the set position.

A roller 127 is provided at the left end of the orthogonal direction restricting portion 126 so as not to be scratched when the mold is contacted with the roller 127. The roller 127 rotates about the center of rotation perpendicular to the paper surface, As shown in FIG.

The angle adjusting unit 128 adjusts the setting angle of the mold by sensing the change in the shape of the outer circumferential surface of the mold and restricting the rotation of the mold seating unit 122. [

That is, the mold rotates in a state of being seated in the mold seating portion 122, and the outer circumferential surface of the mold is partially cut. Accordingly, the angle adjusting unit 128 may be provided with a separate sensor so as to stop the rotation of the mold seating unit 122 when the mold is not sensed.

On the other hand, in the mold whose position is adjusted by the mold position adjusting unit 120, the upper mold and the lower mold are in a state of being merged with each other. Accordingly, the upper mold must be separated so that the finished lens product can be taken out. To this end, the upper mold type pick-up unit 130 is provided on the right side of the mold position adjusting unit 120 (as viewed in FIG.

The detailed configuration of the image forming unit 130 will be described below with reference to FIG.

As shown in the figure, the upper mold pick-up unit 130 has a configuration for picking up only the upper mold positioned on the upper side among the constituent elements of the mold and possessing the upper mold for a predetermined period of time.

The upper adsorption unit 132 functions to lift the upper shape by a suction force generated selectively at the lower end.

The upper adsorption unit 132 can move linearly in the up / down direction. For this purpose, a lifting unit 134 is provided above the upper adsorption unit 132. When the length is increased, the lower end portion can be lifted by the suction force, and the lower end portion is lifted up by the suction force. When the length is reduced, the lifted portion 134 is lifted up .

A sliding portion 136 is provided on the right side of the upper adsorption unit 132. The sliding part 136 is long left and right with the upper adsorption part 132 and the elevation part 134 being supported at the same time and the left part is elongated to the left side so that the upper adsorption part 132 is left / It can be transported in the right direction.

Therefore, if the length of the sliding part 136 is reduced in a state where the upper mold is attracted to the upper adsorption part 132, the mold keeps the inside open. Therefore, the charging of the lens raw material B, The finished product can be taken out.

Also, since the length of the sliding part 136 is reduced to prevent the upper mold from being present on the upper side of the mold, the interference of the diaphragm unit 170 can be avoided.
