UV light curing of mobile phone camera (camera module)

UV light curing of mobile phone camera (camera module)

The mobile phone camera (camera module) is composed of CMOS components / plastic parts / lenses and other components. UV glue is widely used in the production process. In the selection of light curing equipment, depending on the application, a UV curing box or a UV conveyor curing equipment will be selected .

UV curing box application: The size of the mobile phone camera is generally small and sensitive to temperature.The Intelliray 400 curing box can cure 50-200 pieces at a time according to the size of the camera.The usual UV glue completes curing in 30-60 seconds, and the curing temperature is low At 70 degrees. No external cooling system is required, the compact shape is very suitable for the production of workbench. And it can be used with 4 different lamps to meet different applications. The following is a typical case

# 1 Visible light VISBLE (420NM) enhanced lamp tube to solve IR filter

A company needs IR filters on cameras.Among them, the IR filter can pass through the wavelength range of 390-600nm, blocking most UVA (320-390nm) .After switching to UV / visible light curing glue, it encountered curing problems. The main peak of most UV curing equipment is at 365nm.To achieve the required visible light intensity, it is usually necessary to extend the curing time. The ultraviolet light in it will be converted into heat, which will cause the camera of the mobile phone to overheat and affect the performance of the product. 1 hour curing time.

For this application, our company proposes INTELLIRAY 400 with visible light 420nm enhanced light bulb, the main spectrum is concentrated in 395-445nm, which can complete UV curing in 30-60 seconds. Power consumption does not exceed 400W, temperature does not exceed 70 degrees, perfect Solve the actual problems of customers,

# 2 Improve from traditional large curing machine to multiple small curing boxes:

The camera mass production process, the current method of many factories, is that multiple manual or automatic dispensing stations share a large set of UV curing equipment, usually 8-10KW. The noise is large, the dust is large, and the electrical power consumption is large. The efficiency of the curing method is actually very small due to the fact that the curing components are very low. For many products, the cleanliness is very high and the temperature requirements are also very high. This production method is obviously not suitable. Plus a large number of invalid turnover processes , Is another way of waste.

The current improvement method is to use an efficient small curing box, which is directly placed next to the dispensing station, and a set of 2 stations can be shared.

Application of small conveyor belt curing equipment: For some productions organized in assembly line, you can use low temperature, small, low power UV CONVEYOR 40 conveyor belt curing system, or use SUNRAY400 or 600 to form a customized conveyor belt system, generally 2000mJ / cm2, The conveyor belt speed can reach 1200mm / min. For mobile phone cameras, the curing efficiency is very high. At the same time, the power consumption is less than 6800W, and the curing temperature does not exceed 70 degrees.
