Description

Technical Field

[0001] The invention relates to the field of UV light curing equipment, in particular to a UV curing furnace with digital control of light energy. Background Art

[0002] In order to ensure the waterproof performance and stability of circuit boards during operation, it is necessary to perform glue dispensing operations at important contact points of the sheet material, and then use UV light to fix the sheet material after dispensing. This dispensing solution generally uses UV glue. After the dispensing is completed, the sheet material needs to be placed in a UV curing oven for curing.

[0003] However, the existing UV curing oven has only one power switch. After the sheet is placed in, the curing time needs to be controlled according to the actual situation. At present, the residence time of the sheet in the UV curing oven is generally adjusted by adjusting the chain speed. If the residence time is too short, the UV glue will not be cured firmly. If the residence time is too long, it will affect the production efficiency of the sheet. Therefore, it is difficult to accurately control the curing time.
