IEE Jpn., pp. 494-497, 2002); and injection molding is mainly used for injection molding. Microlens arrays can also be fabricated by mass production of optical lenses up to 100 mm in diameter. To manufacture optical lenses by injection molding, firstly, the quantitative optical plastic heated into a fluid is injected into the molding cavity of the mold through a runner, and then formed under heat and pressure conditions, and finally cooled and solidified to open the mold. An initial product of an optical lens can be obtained.

The lens pick-up device 2A includes a robot arm 22 and four pickers 24. The mechanical machine 22 includes a mechanical rod 22 and a chassis 222. The chassis 222 is a regular square or a truncated cone. In the present embodiment, the bottom helmet 222 is a regular square. The mechanical rod 22 is perpendicular to the chassis π] and is fixed to the center of the chassis 222. The _ °Hao suction hoist 24 includes an evacuation tube 240 for evacuation and a suction tube 242 for sucking the lens. One end of the exhaust pipe 24 is connected to a vacuum pump (not shown), and the other end is connected to one end of the suction pipe 通过 through a pneumatic valve 244. The other end of the suction tube 242 has a suction head 246 which is a disc-shaped nozzle. The suction tube is made of metal such as iron or stainless steel, and can also be made of materials such as hard plastic. The suction head 246 can be made of rubber and is detachable. In the present embodiment, the air pressure valves 244 of the four suction devices 24 are respectively fixed to the four side walls of the bottom plate 222. The four suction devices are in parallel with each other and are perpendicular to the chassis 222. When picking up the lens, the four suction tubes 242 - the end of the suction head 240 are respectively opposed to the four lenses to be picked up. It will be appreciated that the size of the chassis 222, the spacing between each of the pickers 24, and the number of pickers 1379804 24 can be designed according to the settings of the mold cavity. ‘ The process of picking up the lens by the above lens picking device 20 will be described in detail below with reference to the accompanying drawings. Referring to Fig. 3, first, a four-hole injection molding die is formed (not shown) to form a lens preliminary product, and the lens 26 is separated from the material head by a shearing machine. The position of the robot arm 22 is then adjusted so that the four pick-up heads 246 of the lens pick-up device 20 are respectively opposed to the four lenses to be picked up. Referring to Figure 4, the robot arm 22 is moved in the negative direction of the Z-axis such that the disc-shaped nozzle of the suction head 246 just falls on the upper surface of the lens 26. At this time, four air pressure valves are simultaneously opened • 244 and vacuumed by a vacuum pump, and the pressure in the suction pipe 242 is so small that the air pressure valve 244 can be closed when the lens 26 can be sucked. The robot arm 22 is moved in the positive direction of the Z-axis so that four lenses 26 can be picked up simultaneously. Finally, the machine arm 22 is moved to the tray, the lens 26 is placed in the tray and the air valve -244 is opened, the lens 26 is disengaged from the suction head 246, and the robot arm 22 is returned to the original position for the next picking action.
