Automotive headlight lens, production line and manufacturing method

Abstract

The invention provides a car headlamp lens and a production line and production method thereof. The car headlamp lens comprises a plane mirror and a curved mirror and is characterized in that the bottom of the curved mirror is integrally connected with the plane mirror, and a sealed cavity is formed between the plane mirror and the curved mirror. The production line comprises a first branch line and a second branch line and is characterized in that a welding device is arranged at the intersection of the first branch line and the second branch line, the first branch line is provided with a hotforming device and a first conveying device, the second branch line is provided with a second conveying device, the first conveying device is used for conveying a first board for processing the curvedmirror along the first branch line, the second conveying device is used for conveying a second board for processing the plane mirror along the second branch line, the hot forming device is used for processing the curved mirror on the first board, and the welding device is used for integrally welding the bottom of the curved mirror and the plane mirror. The production method includes: producing the curved mirror and the plane mirror through pressure forming, and integrally connecting the bottom of the curved mirror with the plane mirror. The car headlamp lens and the production line and production method thereof have the advantages that easiness in processing is achieved, and high production efficiency and yield are achieved.

Description

technical field [0001] The invention belongs to the field of lens processing, and more specifically relates to an automobile headlight lens, a production line and a manufacturing method. Background technique [0002] In the field of car lights, LED headlights have begun to replace traditional halogen lamps and xenon lamps. Models equipped with LED headlights have been launched, but the manufacturing technology of the lens, a key part of the car light, is still restricted due to its thick-walled structure. Model mass production bottleneck. [0003] Plastic thick-walled lens is a new type of innovative product. It has extremely high requirements for weight, appearance, and surface shape, and must meet the requirements of light distribution. This thick-walled transparent product is generally made of PMMA or PC plastic materials. The general injection molding is different, and its technical difficulty is relatively high. At present, there are two methods: one-time injection mol...
