Rapid aa assembly method and device for camera

Abstract

The present invention provides a quick AA assembly method of a camera. In the assembly method, a reference chip is fixedly arranged at the AA station so that the lens is actively aligned with the reference chip at the AA station to obtain the position and posture data of the lens, that is, the first data; By obtaining the position and posture data of the chip to be installed on the assembly station and the reference chip on the AA station, that is, the second data, the target of the lens located on the assembly station is obtained by calculating the first data and the second data location, so that the chips to be installed with glue are solidified at the assembly station and the lens to obtain finished materials, without the need to power on and actively align the chips to be installed on the assembly station; the assembly station does not need to be powered on, and the lens and The chip is not blocked during the curing process, which improves the curing effect; the dispensing station and the AA process are executed in parallel to improve the efficiency of assembly; in addition, the reference chip is always fixed on the AA station, which simplifies the fixture mechanism and circuit design, reducing the assembly cost.

Description

technical field [0001] The invention relates to the field of semiconductor manufacturing, in particular to a camera fast AA assembly method and device. Background technique [0002] Semiconductors are widely used in mobile phones, automobiles, sensors and other fields. As a core component of mobile phones and computers, semiconductors are becoming more and more technological, social demand is gradually increasing, semiconductors tend to be miniaturized, and the manufacturing quantity is huge. [0003] With the gradual increase in camera requirements, the requirements for semiconductor manufacturing precision also increase. In the manufacturing process of semiconductors, it is usually necessary to use optical active alignment equipment, that is, active alignment (Active Alignment Machine, AA) process. The AA process can adjust all six degrees of freedom of the camera to realize the alignment function, and is a commonly used adjustment process in the prior art. [0004] At p...

Problems solved by technology

When the AA is running, the dispensing module is idle; when the dispensing module is running, the AA is idle; the efficiency of the equipment is limited and it is difficult to improve

[0005] In addition, during the AA process, each chip needs to be energized and imaged, and the chip transmission module needs to be equipped with movable energized fixtures, which require high stability and high cost. Accuracy of dispensing module curing
