Background
Recently, digital video cameras, camera phones, network cameras, and the like have been gradually miniaturized and thinned, and accordingly, the size of camera modules has been gradually reduced. With the miniaturization of camera modules, the demand for non-curved lenses has increased day by day, replacing conventional curved lenses.
Such a non-curved lens may be produced by a grinding method or a press molding method, but the grinding method is not suitable for mass production. Therefore, recently, a press molding method has been widely used in which a material is put into an upper mold and a lower mold, the upper mold and the lower mold are assembled with each other, and then the assembly is mounted on a molding machine, and molding is performed by a high-temperature heating step, a pressing step, and a cooling step.
For example, as shown in fig. 1, korean laid-open patent No. 10-2006 and 0001861 discloses an example of an automated molding apparatus for press molding.
The above-described automated lens molding apparatus according to the related art includes: a carrying-in and carrying-out robot which is configured on the lens arraying plate after taking out the molded lens by disassembling the mold carried out from the lens molding device, and inputs new raw materials into the disassembled mold and assembles the disassembled mold; and an orthogonal coordinate type robot for aligning the molded lenses aligned on the lens aligning plate on the lens holder in sequence, and aligning the raw materials from the new raw material holder to the raw material aligning plate in sequence.
However, since the lens array plate and the material array plate are arranged in a state fixed in close proximity, the orthogonal coordinate robot does not operate to prevent collision with the carrying-in and carrying-out robot while the carrying-in and carrying-out robot carries out transfer of the molded lens to the lens array plate.
Therefore, the work of transferring the raw material existing in the raw material holder to the raw material arranging plate cannot be performed, and thus, there is a problem that the entire lens molding cycle period is prolonged.
Thus, as shown in fig. 2, korean patent No. 10-1452709 discloses a raw material feeding and molded lens taking-out automation device that reduces the overall cycle time for transferring a lens to a lens holder by feeding a raw material in a raw material holder to a lens molding device and taking out a molded lens from a mold.
However, the above-described prior art has the following problems.
That is, since the molding apparatus is configured by a plurality of robots including the
Further, as a plurality of robots are provided, the volume of the apparatus increases, and therefore, the degree of space usage also decreases.
On the other hand, the above-mentioned conventional techniques all involve an apparatus for molding a lens by feeding a previously molded material. That is, the material of the related art shown in fig. 1 is formed into a shape similar to a finished lens by preliminary molding, and the material of the related art shown in fig. 2 is formed into a low-height cylindrical shape and has a chamfer formed at an edge of an upper end portion.
Therefore, when the raw material is placed inside the mold, directivity is considered, and thus, productivity is reduced.
Further, since it is difficult to transfer and pick up the product, it is not preferable because the manufacturing cost of the device increases when designing a more precise product.
Thus, as shown in fig. 3, korean laid-open patent No. 10-2008-0076922 discloses an optical device molding apparatus for molding a lens using a raw material in a ball shape.
However, the conventional technique in fig. 3 has a problem that it is not described how to pick up and transfer the ball-shaped material, and even if the ball-shaped material is used, it is difficult to store, pick up, transfer, and position the lens to be molded when the size of the lens is extremely small.
