Introduction:

Some electronic products have high quality requirements and cannot have bubbles during gluing. However, ordinary gluing equipment can only achieve vacuum gluing of glue and cannot achieve a vacuum gluing environment at the end of the product gluing process; The intelligent fluid control automation manufacturer has developed an intelligent device for this process end that can inject glue in a vacuum environment; The vacuum glue filling equipment of Zhonghui Hanqi has been upgraded and renovated on the original equipment and process, which can achieve zero bubbles in the glue filling product, no dripping or leakage in the vacuum state, and can be used for filling complex structured products. The design has added an online track with a high degree of automation, suitable for 5:1~1:1 two-component glue filling and sealing (can also be customized according to customer processes).

The widespread use of vacuum gluing equipment in the electronics industry is increasing, especially in the packaging of electronic products such as transformers, relays, power supplies, motor coils, etc., which require gluing work to be completed in a vacuum environment. This is also something that ordinary glue filling machines cannot replace. Simply put, a vacuum glue filling machine is based on a regular glue filling machine, which exhausts the air in the material tank and maintains a vacuum state, and then the environment for product glue filling is also maintained in a vacuum state, which can prevent the formation of bubbles. And its use is basically not affected by external environment interference, so the equipment performance is stable, the glue injection accuracy is high, and the operation is reliable. Due to these characteristics, compared to pouring under normal pressure, the adhesive adhesion is too high and bubbles are extremely difficult to eliminate. There are bubbles inside the product and the adhesive is extremely difficult to penetrate, resulting in uneven surfaces and vastly different performance of the poured product. At this point, the function of the vacuum glue filling machine can be reflected. The vacuum glue filling machine operates by maintaining an absolute negative pressure state to fill the product 3-4 times. Using the force of negative pressure, the air inside the vacuum box is first evacuated during the filling process, and then the product is filled. The glue can quickly penetrate into the interior of the product, and the bubbles generated by the filling impact and the contact between the glue and the product can also be quickly evacuated under negative pressure, thereby ensuring the high performance of the product.
