Umbrella frame turntable of lens coating machine

Abstract

The invention relates to an umbrella frame turntable of a lens coating machine. The umbrella frame turntable of the lens coating machine consists of a pot body fixing ring (1), a movable connecting arm (2), a lower connecting seat (3) and an upper connecting seat (4), wherein a pot body lifting lug (1-1) is arranged on the upper circumference of the pot body fixing ring; four pot body lifting lugs(1-1) evenly distributed at 180 degrees of the circumference of the pot body fixing ring (1), and the included angle of two adjacent pot body lifting lugs (1-1) is 60 degrees; and the lower connecting seat (3) is provided with lower seat lifting lugs (3-1), four lower seat lifting lugs (3-1) distributed at 180 degrees outside the circumference of the lower connecting seat (3), one end of each four movable connecting arms (2) is connected together with each pot body lifting lug (1-1), and one end of each four movable connecting arms (2) is connected together with each lower seat lifting lug (3-1). According to the umbrella frame turntable of the lens coating machine, the vibration caused by the rotation of the pan body is effectively prevented, and the umbrella frame turntable is fixed ina manner of the upper and lower connecting seats, so that the concentricity is high and the stability is good.

Description

technical field [0001] The invention relates to the field of lens processing equipment, in particular to an umbrella frame turntable for lens coating. Background technique [0002] Resin lenses are more and more widely used in various glasses. They have the following advantages: light weight, impact resistance, non-fragile and safe, comfortable to wear, easy to process, wide application, and rich product series (such as single vision, double vision, etc.) light, multi-focal, cataract, discoloration, etc.), the ability to attract ultraviolet rays is higher than that of glass lenses; it can be dyed into various colors; the thermal conductivity is low, and the situation of "water mist" caused by water vapor is better than that of glass lenses. The general processing flow of resin lenses mainly includes the following parts: monomer preparation, module casting, polymerization curing (first curing), mold opening and edging, lens cleaning, post-curing, testing). The function of ad...
