Description

Technical Field

[0001] This utility model relates to the technical field of lens bonding, specifically to a dual-station P-lens bonding machine. Background Technology

[0002] In lens assembly design, a bonded lens is typically used, consisting of a convex lens and a concave lens glued together. The convex lens focuses light and produces positive chromatic aberration, while the concave lens diverges light and produces negative chromatic aberration. By designing the curvature and materials of the two lenses, their chromatic aberrations can cancel each other out, significantly reducing or even eliminating overall chromatic aberration and improving image sharpness and color reproduction accuracy. Furthermore, the contact surface between the bonded lenses is no longer an air interface, thus reducing the number of reflective surfaces and increasing light transmittance.

[0003] Our company previously developed an integrated assembly equipment for cemented lenses with authorization announcement number CN110877002B. The two centering mechanisms of this equipment are set side by side on the same side of the turntable mechanism. When the centering and picking robot transfers the semi-finished lenses, it needs to move along three directions: the X-axis, Y-axis, and Z-axis. Moreover, the robot basically spans across the turntable mechanism, which is too large. Therefore, it has to be set up as a gantry structure, which makes the structure of this centering and picking robot complex and inconvenient to maintain. Utility Model Content

The upper lens feeding mechanism is docked with the carrier fixture at the third position to place the upper lens onto the lower lens that has been glued on the carrier fixture, thereby obtaining the P lens semi-finished product. The transfer mechanism, which docks with the carrying fixture at the fourth position, is used to transfer the P-lens semi-finished product. Two centering mechanisms are provided, located at opposite ends of the transfer mechanism, to alternately receive the P-lens semi-finished products transferred by the transfer mechanism, and to center and solidify the P-lens semi-finished products to obtain the finished P-lens.

The lower lens alignment cylinder gripper 11, the lower lens inspection camera 12, and the lower lens NG material cylinder 13 are all located below the feeding trajectory of the first X-axis lens handling module 35. During the process of the lower lens handling suction pen 352 moving the lower lens from the lower lens Y-axis material tray handling module to the carrier fixture 21, it is first aligned by the lower lens alignment cylinder gripper 11, and then the lower lens inspection camera 12 inspects the front and back and appearance of the lower lens. If the inspection is unqualified, the lower lens is moved to the lower lens NG material cylinder 13; if the inspection is qualified, the lower lens is moved to the carrier fixture 21. The upper lens inspection camera 14 and the upper lens NG material cylinder 15 are both located below the feeding trajectory of the second X-axis lens handling module 53.
