TW200708789A - Jig for precisely assembling optical lens and method thereof - Google Patents

Abstract

The present invention discloses a machine for precisely assembling optical lens and method thereof. This method is mainly to use flexible and automatic alignment, and at the same time, a circular multidirectional extrusion method that can achieve to precisely assemble optical lenses. A device of the method uses a motor to vertically drive a circular rolling jig. The motor is placed on the top of an upper seat. A rolling head that can automatically calibrate its horizontal position is disposed underneath the upper body. In this rolling head, there is a connecting block used to connect a rotatable machine. A screw is used to fasten the connecting block. There is a tube bore designed in the connecting block. The tube bore is fastened to the jib with a bolt. There is a spring disposed beside the bolt to connect and support the jig. The bore diameter of the tube is bigger than the diameter of the bolt in order to reserve space for horizontal displacement. At the same time, a horizontal limiting rod and a spring are used to stabilize the rotation so as to automatically calibrate the horizontal position. The jig is connected with an shaft to drive and rotate. An annular rolling device containing a plurality of balls in the jig is fixed by a ball bearing. When the jig is pressed down, the arc surfaces of balls can be turned to tightly urge against the metal on the side of an optical lens, so that the metal on the side can be gradually and closely attached onto a lens to precisely stabilize the lens together with a fixing apparatus beneath the lens. Besides, a guiding pillar is used to connect and support the upper and the lower seat. After the upper seat is connected with a fixing plate of a gas cylinder with a guide rode, the upper seat is guided to have its up and down strokes. Moreover, there is a fixed positioning device disposed under the jig to coordinate with the movable jig atop, thereby achieving the object of automatically calibrating and directly embedding a lens.
