Mobile phone plastic lens manufacturing method and device

Abstract

The invention discloses a mobile phone plastic lens manufacturing method and a device. The device comprises a female die cavity, a male die cavity and a controller. The female die cavity is provided with a first upper heating unit, a second upper heating unit and a third upper heating unit. The male die cavity is provided with a first lower heating unit, a second lower heating unit and a third lower heating unit. The first upper heating unit, the second upper heating unit and the third upper heating unit are disposed corresponding to the first lower heating unit, the second lower heating unit and the third lower heating unit respectively. The surface of the female die cavity comprises a first inclined plane, a female die cavity plane and a second inclined plane. The first inclined plane, the female die cavity plane and the second inclined plane are connected in order. The surface of the male die cavity is provided with a first bulge and a second bulge. When the female die cavity and the male die cavity are closed together, the first bulge is outside the first inclined plane, and the second bulge is outside the second inclined plane. According to the method and the device provided by the invention, the mobile phone plastic lens is easy to manufacture, and the manufactured mobile phone plastic lens has high quality.

Description

【Technical field】 [0001] The invention relates to the field of manufacturing mobile phone lenses, in particular to a method and device for manufacturing mobile phone plastic lenses. 【Background technique】 [0002] At present, high-end and mainstream mobile phone screens are made of glass. Due to the high cost of glass and complicated processing and production processes, the unit price of glass screens is relatively high, and the glass itself is fragile and not resistant to falling (especially 2.5D and 3D lenses); compression Injection molding lenses require professional molds and compression injection molding machines, and the production costs are relatively high. 【Content of invention】 [0003] In order to solve the above technical problems, the present invention provides a method and device for manufacturing mobile phone plastic lenses. Through simple equipment and processing, mobile phone plastic lenses with obvious slope transition, good light transmittance and non-pol...
