Lens Automatic Sorting Machine

Abstract

The invention discloses an automatic lens sorting machine and belongs to the technical field of lens manufacturing. The sorting machine comprises a frame (1); the frame (1) is provided with a feeding mechanism and a PLC control unit (2); a thickness detection mechanism and a focal power detection mechanism are arranged in order on the feeding mechanism; a sorting mechanism is arranged at the end of the feeding mechanism; the sorting mechanism comprises a sorting platform (3) and a lens recovery conveyor belt; a feeding part is arranged on the sorting platform (3); and a sorting platform driving device is arranged on the frame (1) below the sorting platform (3). The lens the recovery conveyor belt comprises a salable product recovery conveyor belt (4) and a waste product recovery conveyor belt (5). The PLC control unit (2) is respectively connected with the signals of the feeding mechanism, the thickness detection mechanism, the focal power detection mechanism and the sorting mechanism. The invention can realize automatic feeding, automatic detection and sorting of the lenses, has high degree of automation, and can completely replace the manual sorting, improve the detection quality and work efficiency and reduce production cost.

Description

technical field [0001] The invention belongs to the technical field of lens manufacturing, and relates to a sorting machine, in particular to an automatic lens sorting machine capable of distinguishing whether the quality of produced lenses is qualified or not. Background technique [0002] In the lens production process, including the production of glass lens materials and resin lens materials, due to different requirements for thickness, diopter, etc., lenses have various specifications. Even in the production process of lenses of the same specification, the quality of the produced lenses is also different due to the difference in processing technology and the degree of sophistication of the production equipment. For example, in the production process of resin lenses, it is necessary to pour the mold and the rubber ring first, then send the mold to the curing furnace for curing, then open the mold and grind the edge, clean, and then heat-cure. Due to many processes, the pr...

Problems solved by technology

For example, in the production process of resin lenses, it is necessary to pour the mold and the rubber ring first, then send the mold to the curing furnace for curing, then open the mold and grind the edge, clean, and then heat-cure. Due to many processes, the produced The quality of the lens may not be all qualified. Therefore, the produced lenses must be inspected, including light transmittance, central thickness, hardness, vertex, etc. The traditional method is that workers use lens thickness measuring instruments and focal power machines, etc. The instrument detects the lenses one by one, analyzes and judges the quality of the lenses, and if it finds out-of-standard lenses such as thickness and focal power, it will be rejected. Due to manual inspection of lenses, the efficiency is relatively low
