在工业生产的众多环节中，封胶是确保产品密封性、稳定性与耐久性的关键步骤。从建筑材料到电子产品，从汽车制造到包装行业，封胶工艺无处不在。而全自动封胶线的出现，更是革新了封胶作业模式，成为众多企业提升生产效率与产品质量的得力助手。

Sealing is a crucial step in ensuring the sealing, stability, and durability of products in various stages of industrial production. From building materials to electronic products, from automobile manufacturing to packaging industry, sealing technology is ubiquitous. The emergence of fully automatic sealing lines has revolutionized the sealing operation mode and become a powerful assistant for many enterprises to improve production efficiency and product quality.

一、工作原理深度剖析

1、 In depth analysis of working principle

全自动封胶线以先进的自动化控制技术为核心，融合精密机械传动与精准的胶水计量系统，实现封胶流程的全自动化操作。其工作流程主要分为以下几个关键环节：

The fully automatic sealing line is based on advanced automation control technology, integrating precision mechanical transmission and accurate glue metering system to achieve fully automated operation of the sealing process. The workflow mainly consists of the following key steps:

物料输送：通过高精度的皮带输送机、链条输送机或滚筒输送机等，将待封胶的产品平稳且准确地输送至各个工位。在输送过程中，传感器实时监测产品位置，确保其精准定位，为后续的封胶作业提供基础。例如在电子元件的封胶中，传感器可精确识别元件位置，保证胶水涂抹在指定区域。

Material transportation: The products to be sealed are smoothly and accurately transported to various workstations through high-precision belt conveyors, chain conveyors, or drum conveyors. During the conveying process, sensors monitor the position of the product in real-time to ensure its precise positioning, providing a foundation for subsequent sealing operations. For example, in the sealing of electronic components, sensors can accurately identify the position of the components, ensuring that the glue is applied to the designated area.

胶水供给与混合（针对双组份胶水）：对于单组份胶水，储胶桶直接通过管道与涂胶设备相连，利用气压或泵压将胶水输送至涂胶头。而双组份胶水则需要更复杂的供给系统，通过专门的比例泵或混合管，按照预设比例精确混合两种胶水，确保胶水性能稳定。像汽车车身密封胶的涂覆，双组份胶水的精确混合能保证密封效果和强度。

Glue supply and mixing (for two-component glue): For single component glue, the glue storage tank is directly connected to the glue application equipment through a pipeline, and the glue is transported to the glue application head using air pressure or pump pressure. And two-component glue requires a more complex supply system, which precisely mixes the two types of glue according to the preset ratio through a specialized proportioning pump or mixing tube to ensure stable glue performance. The precise mixing of two-component adhesive, such as the application of car body sealant, can ensure the sealing effect and strength.

涂胶作业：这是封胶线的核心环节，根据产品的形状、尺寸和封胶要求，选用不同类型的涂胶设备。如点胶阀适用于小剂量、高精度的点胶作业；喷射阀可实现高速、非接触式涂胶，适用于对速度要求高的场景；螺杆泵则常用于高粘度胶水的均匀涂布。在手机外壳的封胶中，喷射阀能快速准确地在外壳边缘涂布胶水，提高生产效率。

Gluing operation: This is the core link of the sealing line, and different types of gluing equipment are selected according to the shape, size, and sealing requirements of the product. The dispensing valve is suitable for small dose, high-precision dispensing operations; The spray valve can achieve high-speed, non-contact adhesive coating, suitable for scenarios with high speed requirements; Screw pumps are commonly used for uniform coating of high viscosity adhesives. In the sealing of mobile phone cases, the spray valve can quickly and accurately apply glue to the edges of the case, improving production efficiency.

固化与检测：涂胶完成后，产品进入固化区域，根据胶水类型选择合适的固化方式，如紫外线固化、热固化或自然固化。固化后的产品通过视觉检测系统或压力检测设备，检查封胶质量，包括胶线的宽度、高度、连续性以及密封性等，确保产品符合质量标准。

Curing and Testing: After the adhesive is applied, the product enters the curing area and the appropriate curing method is selected based on the type of adhesive, such as UV curing, heat curing, or natural curing. After curing, the product is inspected for sealing quality through a visual inspection system or pressure testing equipment, including the width, height, continuity, and sealing of the adhesive line, to ensure that the product meets quality standards.

二、在各行业的应用实例

2、 Application examples in various industries

建筑行业：在中空玻璃的生产中，全自动封胶线发挥着不可替代的作用。它将丁基胶、聚硫胶或硅酮胶等密封胶均匀地涂布在玻璃边缘，形成密封层，有效阻止空气和水分进入，提高中空玻璃的隔热、隔音性能。例如山东广汇力数控机械有限公司的 ZNJ2540 -Ⅰ/Ⅱ 中空玻璃全自动封胶线，适合大规模玻璃深加工企业，能降低生产劳动强度、节省人力，涂胶后玻璃周边饱满无气线，角部充实，表面平整无需修角，还可配备两套供胶系统，两种密封胶切换快捷 。

In the construction industry, fully automatic sealing lines play an irreplaceable role in the production of insulating glass. It evenly applies sealant such as butyl rubber, polysulfide rubber, or silicone rubber on the edge of the glass to form a sealing layer, effectively preventing air and moisture from entering and improving the insulation and sound insulation performance of the insulated glass. For example, the ZNJ2540-I/II fully automatic sealing line for insulated glass from Shandong Guanghuili CNC Machinery Co., Ltd. is suitable for large-scale glass deep processing enterprises, which can reduce production labor intensity and save manpower. After coating, the glass perimeter is full and free of air lines, the corners are full, and the surface is smooth without the need for corner repair. It can also be equipped with two sets of adhesive supply systems, and the two types of sealants can be switched quickly.

汽车制造：汽车车身的密封和零部件的固定都离不开封胶工艺。全自动封胶线用于涂抹车身密封胶、结构胶等，提高车身的密封性、强度和耐久性。在汽车车灯的生产中，封胶线精确地在灯壳边缘涂胶，确保车灯防水、防尘，延长使用寿命。

Automobile manufacturing: The sealing of car bodies and the fixation of components cannot be separated from the process of sealing with sealant. The fully automatic sealing line is used to apply body sealant, structural adhesive, etc., to improve the sealing, strength, and durability of the body. In the production of car headlights, the sealing line is precisely applied to the edge of the lamp housing to ensure that the headlights are waterproof, dustproof, and extend their service life.

电子领域：电子元器件的固定、电路板的防护等都需要高精度的封胶。全自动封胶线为电子元器件涂抹固定胶、导电胶等，确保电子产品的稳定性和可靠性。如在芯片封装中，封胶线将胶水精确地涂覆在芯片周围，保护芯片免受外界环境影响。

In the field of electronics, high-precision sealing is required for fixing electronic components and protecting circuit boards. The fully automatic sealing line applies fixing adhesive, conductive adhesive, etc. to electronic components to ensure the stability and reliability of electronic products. In chip packaging, the sealing line precisely applies glue around the chip to protect it from external environmental influences.
