Dispensers are indispensable in the production process of 3C electronic products for dispensing and coating fluids of various viscosities to precise locations on the surface or inside the product. Because different products need to use different viscosity glue, the higher the viscosity, the more likely to produce pulling phenomenon in the dispensing process, resulting in poor fluidity, uneven coating, can not play the role of bonding, sealing.

How to solve the dispensing pull, not limited by the viscosity of the fluid, to maintain a stable and consistent, the hardware level can choose to use the dispensing valve, the use of pneumatic principle of operation, to regulate the working air pressure of the fluid, to avoid the phenomenon of dispensing pull. The speed of automatic dispensing is fast, usually up to 30mm/s, so it is necessary to use the high-speed camera to study the phenomenon of dispensing and pulling under different air pressures, which is used to experiment and finalize the optimal value of the working condition air pressure corresponding to different viscosity fluids.

Goertek precision equipment dispenser using Revealer thousand frame-level 1080P high-speed camera M220, take advantage of small size, set up in the narrow space within the dispenser, to look down at a 15° angle, clearly capture the 10cm square field of view of the dispensing and drawing of the state of the different air pressures, to improve the production process.
