The complete process of UV adhesive dispensing

In the field of precision electronics assembly and optical device manufacturing, UV adhesive dispensing process quality directly impacts product performance and yield. As a professional fluid control solution provider, we have compiled the following key operational points for you:

I. Environmental Control Key Points

The work area should be kept clean and dust-free.

The ambient temperature is recommended to be maintained within the process requirements.

Avoid direct sunlight and strong light.

Maintain proper air circulation.

II. Material Preprocessing Suggestions

• Thoroughly stir before use to ensure uniform components.
• Adjust the temperature appropriately according to process requirements.
• Seal and store carefully after opening.
• Check the material expiration date.

III. Equipment Debugging Specifications

Dispensing needle selection should consider the adhesive properties.

Air pressure parameters need to be adjusted according to viscosity.

The dispensing volume needs to be verified through multiple tests.

UV lamp intensity needs to be calibrated regularly.

IV. Key Process Control

The dispensing path needs to be optimized.

Glue volume control must remain stable.

Curing time must be strictly controlled.

Clean immediately after dispensing.

V. Common Problem Solutions

→ Glue stringing: Adjust the dispensing height and back suction parameters.
→ Incomplete curing: Check the UV lamp status and irradiation time.
→ Bubble problems: Optimize the deaeration process and dispensing speed.
→ Poor adhesion: Perform proper surface pretreatment.

VI. Safety Operation Instructions

• Operators must wear safety glasses.
• Avoid direct skin contact with the adhesive.
• No open flames are allowed in the work area.
• Waste adhesive must be professionally disposed of.
