A lens automatic pressing device for a projection unit

Abstract

The invention provides an automatic lens press-fitting device for a projection unit. The automatic lens press-fitting device comprises a workbench (1), and is characterized in that a portal frame (2) is arranged on the workbench (1), and a cross beam (21) on the portal frame (2) stretches over the workbench (1); guide rails (3) are arranged on the cross beam (21), one end of each guide rail (3) is movably connected with a pressing ring grasping part (4), and the other end of each guide rail (3) is movably connected with a lens grasping part (5); the portions, at the two ends of the guide rails (3), of the cross beam (21) are provided with transverse moving parts (6) connected with the pressing ring grasping part (4) and the lens grasping part (5); and the installing position of a pressing ring positioning mechanism (8) corresponds to that of the pressing ring grasping part (4), and the installing position of a lens positioning mechanism (10) corresponds to that of the lens grasping part (5). By means of the automatic lens press-fitting device, labor intensity is greatly reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of auxiliary processing of automobile lamp parts, in particular to an automatic lens pressing device for a projection unit. Background technique [0002] At present, the projection unit used in the headlights of automobiles mainly includes a lens, a lens bracket, a reflector, and a light source; the light source is fixedly installed at the bottom of the reflector, and the lens is fixedly installed in the lens bracket; The strength must be controlled well, so as to avoid the quality problems of shaking and breaking of the installed lens; the current lens installation method mainly relies on manual installation. When installing, first put the lens in the lens holder, and then Put the pressure ring on the lens, and then press the fixed piece on the lens bracket on the pressure ring with clamps; because the installation is manual, the production efficiency is low, the labor intensity is high, and the strength during the i...
