Camera module dispensing process solution provider

A good dispensing solution can do twice as much with half the effort. For mobile phone terminal brand manufacturers, the smaller the camera is, the better the function integration is, and the higher the cost performance is. Therefore, the application of functional technologies such as VCM, OIS, dual cameras and optical zoom will be more and more popular. This requires more and more precise parts of the camera module, and it will be more and more difficult to dispensing. There are 8-11 dispensing processes in a camera module. It can be said that the whole camera module is bonded and fixed by glue step by step.

Camera module mainly includes: mobile phone front and rear cameras, tablet front and rear cameras, notebook cameras, car cameras, etc. In recent years, the camera module has developed rapidly, from low pixel to high pixel, from fixed focus to automatic focusing. In the future, advanced functions such as optical anti shake and 3D imaging will be added.

The camera module mainly includes the following parts: FPC, sensor, lens, VCM, etc. its internal structure is complex and precise. Many components need to be assembled by dispensing, and the assembly of VCM is more difficult. At present, there are the following difficulties in the automatic dispensing process of camera modules on the market:

The components are too small, and the traditional dispensing equipment can not meet the requirements;

High requirements for visual system recognition and positioning ability;

Taking the production process of attaching the filter after dispensing the lens base in the camera module as an example, the dispensing width of the step on the base is only 0.4mm, and the dispensing line width is required to be within 0.3mm without glue overflow; The error of attaching the filter to the base is less than 0.05mm. In this way, the efficiency is very low, and the mounting accuracy can not be guaranteed.

How can we improve the production capacity and position accuracy of mounting? Our recommended solution is to use the same machine for dispensing and mounting filters. Firstly, CCD is used to identify and automatically locate the lens base, and then precise dispensing is carried out on the base; First grab the filter, adjust its angle through CCD to ensure the position accuracy of the filter and the base, and then paste it. Adopting the machine integrating dispensing and mounting filter to realize dispensing of lens base and assembling filter can first save labor cost; The second is to improve energy saving, and the production capacity can reach more than 1500 pieces / hour, which is more than twice that of manual mounting; The key is that the mounting accuracy can be controlled within 0.05mm, which is higher and more stable.
