Abstract

A lens assembly system comprises a holder, a lens assembly fixture on the holder, an elastic element and a push rod. The lens assembly fixture comprises a first shell, a second shell connected with the first shell and a post rod sleeved on the second shell. The first shell is used to contain the drawtube of the lens module. A through hole is provided at one end of the second shell. The post rod is contained with the through hole to push an optical element contained in the second shell out of the second shell and connected with the holder. The push rod is coaxially arranged towards one end of the first shell in interval. The lens assembly system and the assembly fixture make the lens not been sloped so as to improve the nondefective assembly rate. The invention also relates to a assembly method of the lens assembly system.

Description

technical field [0001] The present invention relates to a lens module assembly technology, in particular to a lens assembly fixture, an assembly system and an assembly method having the assembly fixture. Background technique [0002] With the continuous development of science and technology, portable electronic devices such as mobile phones are widely used and tend to be light, beautiful and multi-functional. The camera function is an additional function of the popular mobile phones in recent years. A digital camera module used in a mobile phone must not only meet the requirements of thinness, lightness and compactness, but also have high photographic performance. The digital camera lens module assembly method is one of the main factors that determine the photographic performance. In the digital camera lens module assembly process, the lens assembly fixture and its assembly system become the key factors to improve the lens module assembly ability and product yield. One, the...
