Abstract: A method for making a plurality of light blocking plates is provided. Firstly, a plurality of conical frustums are formed on a metal substrate, and each of the conical frustums tapers in a direction away from the metal substrate. Secondly, an opaque to-be-solidified film is formed on the metal substrate, and each of the conical frustums extends through the to-be-solidified film. Thirdly, the to-be-solidified film is solidified. Fourthly, the solidified film is separated from the metal substrate and the conical frustums, thus obtaining a light blocking plate module comprising a plurality of light blocking plates. Lastly, the light blocking plate module is cut into a plurality of individual light blocking plates.

Abstract: A portable electronic apparatus includes a main body, a camera device, and a supplementary light device. The camera device and the supplementary light device are fixed on the main body. The supplementary light device includes a light module, a lens module, and a motor. The light module includes a circuit board, a light source, and a heat sink opposite to the light source. The lens module includes a lens barrel and a plurality of lenses received in the lens module. The motor drives the lens module to change the intensity distribution of the light from the light module.

Abstract: A mold core includes a substrate, rounded deposition islands distributed on the substrate, and molding layer portions formed on the deposition islands. Each of the molding layer portions encloses a corresponding deposition island.

Abstract: One present embodiment provides a method for manufacturing a mold. In the method, firstly, a master die is provided. The master die includes a molding surface, the molding surface having a plurality of predefined structures thereon. Secondly, a melted PDMS material is applied on the molding surface using a spin coating process. Thirdly, the melted PDMS material is cured to form a mold. Finally, the master die is removed.

Abstract: An exemplary adhesive dispenser includes a container configured for supplying an adhesive, a plurality of nozzles configured for dispensing the adhesive, and a temperature controller connected between the container and the nozzles. The temperature controller has a chamber defined therein, and the chamber is configured for accommodating the adhesive. The container and each nozzle communicate with the chamber respectively. The temperature controller is configured for maintaining the adhesive therein in a predetermined temperature.

Abstract: An exemplary a method for manufacturing a lens is provided. In the method, a first lens preform and a second lens preform is formed. The first lens preform includes a first surface and an opposite second surface. The second lens preform includes a third surface and an opposite fourth surface. An oxygen plasma is applied to the second and fourth surfaces so as to form a number of groups capable of being irreversibly bonded. The second surface is contacted with the fourth surface. The groups capable of being irreversibly bonded take place an irreversible bonding reaction to chemically combine the second and fourth surfaces, thereby obtaining a double sided lens preform. The double sided lens preform is diced into a number of double side lenses.

Abstract: An exemplary light blocking plate includes a through hole defined at the center thereof and an opaque portion surrounding the through hole. The light blocking plate is comprised of a blackening agent and a PDMS.

Abstract: An exemplary glue dispenser for dispensing a glue on a workpiece includes a nozzle for dispensing the glue on the workpiece, a working platform for supporting a workpiece thereon, and a heating device mounted on the working platform. The heating device is configured for maintaining the workpiece in an elevated temperature, which is higher than a temperature of the glue.

Abstract: An exemplary alignment apparatus can align a first layer with a second layer. The first layer has a first alignment pattern. The second layer has a second alignment pattern. The alignment apparatus includes a supporting device for supporting the first layer and the second layer, a light pervious reference plate, and a viewing and adjusting mechanism. The light pervious reference plate has a first reference pattern spatially corresponding to the first alignment pattern on the first layer, and a second reference pattern spatially corresponding to the second alignment pattern on the second layer. The viewing and adjusting mechanism is adapted for assisting a human operator to align the first reference pattern with the first alignment pattern and the second reference pattern with the second alignment pattern.
